Multi-track vibratory bowls usually need to maintain a consistent feed rate across the various tracks. However, variables such as tooling and parts falling onto lower tracks can cause the feed rates of each track to vary. For most parts, the upper most track features the highest feed rate while the lower tracks have a lower feed rate. This fluctuation, if not accounted for when determining parts feeding system requirements, may cause delays in production due to missed machine cycles or in worse cases, damage.

As a bowl's amplitude is turned up to achieve a desired feed rate out of the slowest rate track, the faster rate tracks may begin to experience problems associated with back pressure such as overlap and jamming.

Determine whether or not you need tooling to control back pressure
Block the flow of parts at the exit of the bowl and allow them to back up. If the parts naturally relieve their own back pressure, likely, you will not need to do anything. However, if the back up produced jams or bypassed tooling, then consider the following options.

Several options exist for eliminating the problem:

1. Build pressure break tooling.
2. Use air-jets to blow parts off of a track when it is full.
3. Mechanically actuated tooling, such as wipers, can be used to clear parts until they are needed.

Sometimes, the characteristics of a part do not permit the use of pressure break tooling. In cases such as these, the other options may be used. However, the tooling option is often the more simple and less costly choice.

Purpose of a "Pressure Break"

Pressure break tooling prevents parts from jamming into each other when the feed rate of the bowl exceeds the rate at which the parts are used. Overlap and disoriented parts may jam tooling. As above, this is often a problem in multi-track bowls.

How Does It Work?

The tooling relieves pressure on the parts by creating sort of 'by-pass'. When the parts would normally jam, the tooling forces the parts off of the track and back into the bowl or onto a lower track. The technique shown below works exceptionally well with cylindrical parts.

In this particular example, once the parts begin to back up, the parts from behind are forced out and over the next part. The track is not wide enough to support two parts. The excess part falls onto one of the successive tracks below, enhancing feed rate.

Notes for Designing the Tooling

1. Make sure the pressure wedge is at least as wide as the outside diameter (O.D.) of the part.
2. Start with the upper track and place successive lower track tooling after the previous break. This will prevent falling parts from interfering with oriented parts below.

Here are the most common causes of poor vibratory feeder performance:

Electrical Settings

Electrical settings on the controller are a common cause of poor feeder performance. Here are some of the things that should be inspected prior to placing a feeder back into production:

• Check the AC/DC Setting on the Controller and the Vibratory Drive Unit.
  Are they the same?

• Is the cycle output of the controller the same as what the drive unit is tuned for?
  For instance, the controller may output 60 HZ but the base unit may be tuned for 50HZ or vice versa. A variable frequency controller may be able to fix this issue for you automatically.

The feeder controller's internal max adjustment is turned down too low.

This happens quite often when a controller set for one unit is used to power a different unit. The max adjustment may have been turned down to reduce coil hammering on a smaller unit, but when used on a larger unit, it will seem as the the coil is "losing its strength". Refer to the controller instructions, in the vibratory feeder controller section for turning up the max adjustment

Cracked Vibratory Base Unit Springs

A cracked spring will often cause a feeder to slow down. If this seems to happen often to units that are turned on and off, try increasing the soft-stat ramp-up. This helps reduce the shock to tooling as well as springs. Refer to the vibratory base units section for instructions on how to detect broken springs, tune and repair base units.

Tooling Added After the Unit was Tuned

Adding feeder bowl tooling after a base unit is tuned is a very common problem that causes the slow down symptoms. Make sure that the base unit is re-tuned after all tooling is added. This will save a lot of trial and error in the future.

These are just a few of the common problems and oversights we see. Never hesitate to contact ADI for assistance or call 1-(814)-474-5561. We are always eager to help.

Below are excerpts pertaining to the manufacturing sector from the 4th Quarter U.S Productivity and Costs release from the BLS. A complete version of the release is available: 4th Quarter 2006 U.S. Productivity and Costs

Manufacturing Productivity

Output and hours in manufacturing, which includes about 12 percent of U.S. business-sector employment, tend to vary more from quarter to quarter than data for the aggregate business and nonfarm business sectors.

Manufacturing productivity grew 2.2 percent in the fourth quarter of 2006 as output declined 1.6 percent and hours fell 3.7 percent (seasonally adjusted annual rates). The decrease in output was the first since the
second quarter of 2003, when output decreased 2.4 percent. In the third quarter, manufacturing productivity had increased 6.3 percent, reflecting a 4.8-percent rise in output and a 1.5-percent decline in hours (table 3). In durable goods manufacturing, productivity rose 3.3 percent in the fourth quarter as output edged down 0.5 percent and hours fell 3.7 percent (table 4). Among nondurable goods manufacturers, productivity rose 0.9 percent in the fourth quarter as output fell 3.0 percent and hours at work fell 3.9 percent (table 5).

In manufacturing, labor productivity rose 3.9 percent in 2006, slightly less than the 4.2-percent average annual rate from 2000 through 2005. Output increased 5.0 percent and hours rose 1.1 percent in 2006 (table B). There was a 6.2-percent increase in durable goods manufacturing productivity in 2006, as output increased 7.6 percent and hours increased 1.3 percent. Output per hour increased 1.5 percent in nondurable goods manufacturing, as output grew 2.2 percent and hours rose 0.7 percent.

Compensation

Average hourly compensation of manufacturing workers increased 7.3 percent in the fourth quarter of 2006, reflecting increases in hourly compensation of 7.9 percent in durable goods manufacturing and 6.1 percent in
nondurable goods manufacturing. When the decrease in consumer prices was taken into account, real hourly compensation in total manufacturing jumped 9.8 percent in the fourth quarter.

The hourly compensation of manufacturing workers increased 4.1 percent in 2006, slightly less than the 4.6-percent growth rate in 2005. In 2006, hourly compensation rose 5.0 percent in durable goods manufacturing and 2.5 percent in nondurable goods manufacturing. Taking into account the rise in consumer prices, real hourly compensation in manufacturing rose 0.9 percent in 2006 after increasing 1.2 percent one year earlier.

Labor Costs

Unit labor costs for the manufacturing sector increased 5.0 percent in fourth-quarter 2006, following declines of 2.9 percent in the third quarter and 8.8 percent in the second quarter. Unit labor costs rose 4.5 percent in durable goods manufacturing and 5.1 percent in nondurable goods industries in the fourth quarter.

Unit labor costs in manufacturing edged up 0.2 percent in 2006, after decreasing 0.1 percent in calendar year 2005. Unit labor costs in durable goods manufacturing decreased 1.2 percent in 2006, similar to the 1.1-percent decline in 2005. Unit labor costs in nondurable goods manufacturing rose 1.0 percent in 2006 and 0.9 percent in 2005.

THE EMPLOYMENT SITUATION: DECEMBER 2006

Nonfarm employment increased by 167,000 in December, and the unemployment rate was unchanged at 4.5 percent, the Bureau of Labor Statistics of the U.S. Department of Labor reported today. Job gains occurred in several service- providing industries, including professional and business services, health care, and food services. Average hourly earnings rose by 8 cents, or 0.5 percent, in December.

Unemployment (Household Survey Data)

The number of unemployed persons (6.8 million) was about unchanged in December,
and the unemployment rate held at 4.5 percent. Over the year, these measures declined
from 7.3 million and 4.9 percent, respectively.

In December, unemployment rates for the major worker groups--adult men (4.0 percent),
adult women (3.9 percent), teenagers (15.2 percent), whites (4.0 percent), blacks (8.4
percent), and Hispanics (4.9 percent)--showed little or no change. The unemployment
rate for Asians was 2.4 percent not seasonally adjusted. (See tables A-1, A-2, and A-3.)

Total Employment and the Labor Force (Household Survey Data)

In December, both total employment, at 145.9 million, and the employment- population ratio, at 63.4 percent, were little changed. Over the year, total employment grew by 3.1 million and the employment-population ratio rose by 0.6 percentage point. The civilian labor force edged up in December to 152.8 million.
The labor force participation rate, at 66.4 percent, was little changed over the
month, but the rate was 0.4 percentage point higher than a year earlier. (See
table A-1.)

Persons Not in the Labor Force (Household Survey Data)

About 1.3 million persons (not seasonally adjusted) were marginally attached to the labor force in December, 337,000 fewer than a year earlier. These individuals wanted and were available for work and had looked for a job sometime in the prior 12 months. They were not counted as unemployed because they had not searched for work in the 4 weeks preceding the survey. Among the marginally attached, there were 274,000 discouraged workers in December, down from 451,000 a year earlier. Discouraged workers were not currently looking for work specifically because they believed no jobs were available for them. The other 978,000
persons marginally attached to the labor force in December had not searched for
work in the 4 weeks preceding the survey for reasons such as school attendance or
family responsibilities. (See table A-13.)

Industry Payroll Employment (Establishment Survey Data)

Total Employment

Total nonfarm payroll employment increased by 167,000 in December to 136.2 million, following increases of 86,000 in October and 154,000 in November (as revised). Over the year, payroll employment rose by 1.8 million. In December, employment growth continued in several service-providing industries. Employment in construction was about unchanged over the month, and the number of manufacturing jobs continued to trend downward. (See table B-1.)

Professional and Business

Professional and business services employment continued to expand in December with a gain of 50,000. Job gains occurred in services to buildings and dwellings
(13,000) and in management and technical consulting services (7,000). Employment
continued to trend up in architectural and engineering services and in computer
systems design and related services. Temporary help services employment was
little changed over the month and over the year.

Health Care

Health care added 31,000 jobs in December. Employment rose in ambulatory health care services (14,000), hospitals (11,000), and nursing and residential
care facilities (7,000). Over the year, health care employment increased by
324,000, with gains spread throughout the component industries.

Food Services and Drinking Places

Job growth continued in food services and drinking places (23,000) in December.
In the past 12 months, food services added 304,000 jobs, accounting for most of the
over-the-year increase in leisure and hospitality employment.

Finance

In financial activities, commercial banking added 5,000 jobs in December. Employment in financial activities was up by 153,000 over the year; job gains occurred in insurance (46,000) and in credit intermediation (62,000), which includes commercial banking.

Transportation

Employment in transportation and warehousing continued to trend up in December.
Over the year, the industry added 106,000 jobs. Telecommunications employment was
up by 6,000 in December; over the year, however, employment in the industry was essentially unchanged.

Retail Trade

Employment in retail trade was little changed over the month after rising by 39,000 in November. Building and garden supply stores lost 8,000 jobs in December.
Over the year, retail trade employment edged down.

Goods Producing

In the goods-producing sector, employment in mining continued to trend up in December. Job gains in the industry averaged 4,000 per month in 2006.

Construction

Employment in construction was about unchanged in December following losses
in October and November that totaled 53,000. After increasing by 295,000 in 2005, construction employment was little changed in 2006. Over the year, gains in non- residential specialty trades and in heavy construction were largely offset by a
decline in residential specialty trades.

Manufacturing

Manufacturing employment continued to trend down over the month with declines in motor vehicles and parts (-5,000), primary metals (-3,000), and textile mills (-2,000). Over the year, manufacturing employment fell by 72,000 with declines
widespread throughout the component industries.

Weekly Hours (Establishment Survey Data)

The average workweek for production and nonsupervisory workers on private nonfarm payrolls remained at 33.9 hours in December. Weekly hours for factory workers were unchanged at 41.0 hours while overtime increased by 0.1 hour to 4.3 hours. (See table B-2.)

The index of aggregate weekly hours of production and nonsupervisory workers increased by 0.2 percent in December to 105.9 (2002=100). The manufacturing index fell by 0.1 percent to 95.2. (See table B-5.)

Hourly and Weekly Earnings (Establishment Survey Data)

Average hourly earnings of production and nonsupervisory workers on private
nonfarm payrolls increased by 8 cents, or 0.5 percent, in December to $17.04.
Average weekly earnings also rose by 0.5 percent, to $577.66. Over the year,
hourly earnings were up 4.2 percent, while weekly earnings were up 4.5 percent.
(See table B-3.)

Revision of Seasonally Adjusted Household Survey Data

At the end of each calendar year, BLS routinely updates the seasonal ad- justment factors for the labor force series derived from the Current Popula- tion Survey (CPS), or household survey. This year, seasonally adjusted data
for January 2002-November 2006 were subject to revision.

As shown in table B, the revisions to seasonal adjustment did not change the overall civilian unemployment rate for any month of 2006. Revised seasonally ad- justed data for other major labor force series beginning in December 2005 appear
in table C.

The January 2007 issue of Employment and Earnings will contain an article describing the current seasonal adjustment methodology for the household survey data and revised data for the most recent months or quarters for all regularly published tables containing seasonally adjusted household survey data. A copy of the article is available at http://www.bls.gov/cps/cpsrs2007.pdf on the BLS Web site.

Historical data for the household series contained in the A tables of this re- lease can be accessed on the BLS Web site at http://www.bls.gov/cps/cpsatabs.htm.
Revised historical seasonally adjusted monthly and quarterly data for additional
series are available on the Internet at ftp://ftp.bls.gov/pub/special.requests/lf/.

Technical Note

This news release presents statistics from two major surveys, the Current Population Survey (household survey) and the Current Employment Statistics survey (establishment survey). The household survey provides the informa- tion on the labor force, employment, and unemployment that appears in the A tables, marked HOUSEHOLD DATA. It is a sample survey of about 60,000 house- holds conducted by the U.S. Census Bureau for the Bureau of Labor Statistics (BLS).

The establishment survey provides the information on the employment, hours, and earnings of workers on nonfarm payrolls that appears in the
B tables, marked ESTABLISHMENT DATA. This information is collected from payroll records by BLS in cooperation with state agencies. The sample
includes about 160,000 businesses and government agencies covering ap- proximately 400,000 individual worksites. The active sample includes
about one-third of all nonfarm payroll workers. The sample is drawn
from a sampling frame of unemployment insurance tax accounts.

For both surveys, the data for a given month relate to a particular week or pay period. In the household survey, the reference week is generally the calendar week that contains the 12th day of the month. In the establishment survey, the reference period is the pay period including the 12th, which may or may not correspond directly to the calendar week.

Coverage, definitions, and differences between surveys

Household survey. The sample is selected to reflect the entire civilian non institutional population. Based on responses to a series of questions on work and job search activities, each person 16 years and over in a sample household is classified as employed, unemployed, or not in the labor force.

People are classified as employed if they did any work at all as paid employees during the reference week; worked in their own business, profession, or on their own farm; or worked without pay at least 15 hours in a family business or farm. People are also counted as employed if they were temporarily absent from their jobs because of illness, bad weather, vacation, labor-management disputes, or personal reasons.

People are classified as unemployed if they meet all of the following
criteria: They had no employment during the reference week; they were available for work at that time; and they made specific efforts to find employment sometime during the 4-week period ending with the reference week. Persons laid off from a job and expecting recall need not be looking for work to be counted as unemployed. The unemployment data derived from the household survey in no way depend upon the eligibility for or receipt of unemployment insurance benefits.

The civilian labor force is the sum of employed and unemployed persons. Those not classified as employed or unemployed are not in the labor force. The unemployment rate is the number unemployed as a percent of the labor force. The labor force participation rate is the labor force as a percent of the population, and the employment-population ratio is the employed as a percent of the population.

Establishment survey. The sample establishments are drawn from pri- vate nonfarm businesses such as factories, offices, and stores, as well as federal, state, and local government entities. Employees on nonfarm payrolls are those who received pay for any part of the reference pay period, including persons on paid leave. Persons are counted in each job they hold. Hours and earnings data are for private businesses and relate only to production workers in the goods-producing sector and nonsupervisory workers in the service-providing sector. Industries are classified on the basis of their principal activity in accordance with the 2002 version of the North American Industry Classification System.

Differences in employment estimates. The numerous conceptual and method- ological differences between the household and establishment surveys result in important distinctions in the employment estimates derived from the sur- veys. Among these are:

--The household survey includes agricultural workers, the self-employed, unpaid family workers, and private household workers among the employed. These groups are excluded from the establishment survey.

--The household survey includes people on unpaid leave among the employed. The establishment survey does not.

--The household survey is limited to workers 16 years of age and older. The establishment survey is not limited by age.

--The household survey has no duplication of individuals, because individuals are counted only once, even if they hold more than one job. In the establishment survey, employees working at more than one job and thus appearing on more than one payroll would be counted separately for each appearance.

Seasonal adjustment

Over the course of a year, the size of the nation's labor force and the levels of employment and unemployment undergo sharp fluctuations due to such seasonal events as changes in weather, reduced or expanded production, harvests, major holidays, and the opening and closing of schools. The effect of such seasonal variation can be very large; seasonal fluctuations may account for as much as 95 percent of the month-to-month changes in unemployment.

Because these seasonal events follow a more or less regular pattern each year, their influence on statistical trends can be eliminated by ad- justing the statistics from month to month. These adjustments make non- seasonal developments, such as declines in economic activity or increases in the participation of women in the labor force, easier to spot. For example, the large number of youth entering the labor force each June is likely to obscure any other changes that have taken place relative to May, making it difficult to determine if the level of economic activity has risen or declined. However, because the effect of students finishing school in previous years is known, the statistics for the current year can be adjusted to allow for a comparable change. Insofar as the seasonal adjustment is made correctly, the adjusted figure provides a more useful tool with which to analyze changes in economic activity.

- 9 -

Most seasonally adjusted series are independently adjusted in both the
household and establishment surveys. However, the adjusted series for many
major estimates, such as total payroll employment, employment in most super- sectors, total employment, and unemployment are computed by aggregating in- dependently adjusted component series. For example, total unemployment is
derived by summing the adjusted series for four major age-sex components;
this differs from the unemployment estimate that would be obtained by directly adjusting the total or by combining the duration, reasons, or more
detailed age categories.

For both the household and establishment surveys, a concurrent seasonal adjustment methodology is used in which new seasonal factors are calculated
each month, using all relevant data, up to and including the data for the
current month. In the household survey, new seasonal factors are used to adjust only the current month's data. In the establishment survey, however,
new seasonal factors are used each month to adjust the three most recent
monthly estimates. In both surveys, revisions to historical data are made
once a year.

Reliability of the estimates

Statistics based on the household and establishment surveys are subject to both sampling and nonsampling error. When a sample rather than the en- tire population is surveyed, there is a chance that the sample estimates may differ from the "true" population values they represent. The exact difference, or sampling error, varies depending on the particular sample selected, and this variability is measured by the standard error of the estimate. There is about a 90-percent chance, or level of confidence, that an estimate based on a sample will differ by no more than 1.6 stand- ard errors from the "true" population value because of sampling error. BLS analyses are generally conducted at the 90-percent level of confidence.

For example, the confidence interval for the monthly change in total employment from the household survey is on the order of plus or minus 430,000. Suppose the estimate of total employment increases by 100,000 from one month to the next. The 90-percent confidence interval on the monthly change would range from 330,000 to 530,000 (100,000 +/ 430,000). These figures do not mean that the sample results are off by these magnitudes, but rather that there is about a 90-percent chance that the "true" over-the-month change lies within this interval. Since this range includes values of less than zero, we could not say with confidence that employment had, in fact, increased. If, however, the reported employment rise was half a million, then all of the values within the 90-percent confidence interval would be greater than zero. In this case, it is likely (at least a 90-percent chance) that an employment rise had, in fact, occurred. At an unemployment rate of around 5.5 percent, the 90-percent confidence interval for the monthly change in unemployment is about +/- 280,000,
and for the monthly change in the unemployment rate it is about +/- .19
percentage point.

In general, estimates involving many individuals or establishments have lower standard errors (relative to the size of the estimate) than estimates which are based on a small number of observations. The precision of esti- mates is also improved when the data are cumulated over time such as for quarterly and annual averages. The seasonal adjustment process can also im- prove the stability of the monthly estimates.

- 10 -

The household and establishment surveys are also affected by nonsampling error. Nonsampling errors can occur for many reasons, including the failure to sample a segment of the population, inability to obtain information for all respondents in the sample, inability or unwillingness of respondents to provide correct information on a timely basis, mistakes made by respondents, and errors made in the collection or processing of the data.

For example, in the establishment survey, estimates for the most recent
2 months are based on substantially incomplete returns; for this reason, these estimates are labeled preliminary in the tables. It is only after two successive revisions to a monthly estimate, when nearly all sample reports have been received, that the estimate is considered final.

Another major source of nonsampling error in the establishment survey is the inability to capture, on a timely basis, employment generated by new firms. To correct for this systematic underestimation of employment growth,
an estimation procedure with two components is used to account for business births. The first component uses business deaths to impute employment for business births. This is incorporated into the sample-based link relative estimate procedure by simply not reflecting sample units going out of busi- ness, but imputing to them the same trend as the other firms in the sample.
The second component is an ARIMA time series model designed to estimate the
residual net birth/death employment not accounted for by the imputation.
The historical time series used to create and test the ARIMA model was de- rived from the unemployment insurance universe micro-level database, and
reflects the actual residual net of births and deaths over the past five
years.

The sample-based estimates from the establishment survey are adjusted once a year (on a lagged basis) to universe counts of payroll employment obtained from administrative records of the unemployment insurance program. The difference between the March sample-based employment estimates and the March universe counts is known as a benchmark revision, and serves as a rough proxy for total survey error. The new benchmarks also incorporate changes in the classification of industries. Over the past decade, the benchmark revision for total nonfarm employment has averaged 0.2 percent, ranging from less than 0.05 percent to 0.4 percent.
