Stelron Vari-Pak

Stelron Vari-Pak

Linear Pick and Place

GENERAL: The Stelron VARI-PAK provides an integral, compact means for linear "pick and place" operations. Cam driven to handle demanding applications, the VARI-PAK is easily adapted to synchronous (continuous run) or non-synchronous (cycle on demand) applications. The VARI-PAK is available in five sizes with fixed or adjustable stroke ranges. The patented infinitely adjustable stroke range feature is unique to the STELRON VARI-PAK and makes it stand out above the rest. The VARI-PAK is available in two different standard versions; positive cam motion or spring loaded cam controlled motions. A wide variety of cam motions and sequences are available as standard.

CONSTRUCTION & OPERATION: The VARI-PAK unit consists of an X-Y linear ball-bushing slide mounted in rugged cast aluminum housing with a projecting tool plate, to which the user attaches the necessary tooling for the application. Controlled motion of the tool plate is derived from a single steel cam (VIP) or two steel cams (SVIP), both "X" and "Y" axis have independent flame hardened cam tracks. Intermediate lever assemblies, available as either FIXED or VARIABLE type and slide yokes provide the mechanical link from cam motion to the tool plate. Removable guards enclose the internal parts of the main housing.

MATERIALS: All rolling contact elements are hardened & ground for minimum wear and low friction. The yoke slider (when used) is hardened tool steel, contacting the hardened tool steel X & Y yoke members. Ball bearings, needle bearing cam followers and oscillating needle bearings are pre-lubricated and sealed. Linear ball bushings have felt wipers for excluding foreign matter and retaining oil lubricant. Cams are medium carbon steel flame hardened on track surfaces for long life and minimum distortion. The X-Y slide rods are high carbon steel case hardened and ground.

SIZE & RANGE: The VIP (positive cam motion) is available in four sizes with standard strokes up to 3" in the "Y" axis and 10" in the "X" axis. The SVIP (spring-loaded cam controlled) is available in five sizes with standard strokes up to 6" in the "Y" axis and 16" in the "X" axis.

ADJUSTABLE RANGES: The VARI-PAK is unique in providing infinite stroke adjustment within the specified range. The VARI-PAK can also be provided with a fixed, non-adjustable stroke. The fixed stroke model is available at a lower cost for any stroke up to maximum stroke of the specific unit.

SPECIAL DISPLACEMENT STROKES, CAM SEQUENCES & STROKE RANGES: Special stroke lengths or angular sequences other than standard shown may be provided. This would incur a one time only master cam charge.

VARI-PAK WORKSHEET: All orders should be accompanied with the customer worksheet. Motions should be sketched geometrically (in the space provided) relative to the example unit shown. Additionally the timing diagram should be shown sequentially with respect to the unit on the customer worksheet.

Application Examples

Synchronous Motion ~ Continuous Drive:

Synchronous linear pick and place applications are very common. Stelron has an extensive line of cam components that can provide synchronized motions in applications utilizing a high-speed continuous drive or line shaft drive. The examples show a STELRON RWB (Recirculating Walking Beam Pallet Transfer System) designed with multiple VARI-PAKS for a variety of pick and place or linear motions.

Cycle on Demand Drive Packages:

Many applications require non-synchronous operation of components. The Stelron VARI-PAK can be supplied with a cycling drive package allowing independent "Cycle on Demand" operation. The example below shows a STELRON PLC (Precision Link Chassis) with multiple VARI-PAKS for a variety of pick and place motions.

Here the smooth cam controlled movement of the VARI-PAK is maintained while adding the control flexibility of having an independent motor drive. The VARI-PAK is often used for "Cycle on Demand" applications.

How to design a STELRON “Vari-Pak”into your application.

4

When adjusting the “X” axis stroke, the “R” dimension changes in the retracted position by the exact amount of the change in stroke. The Fixed “X” dimension equals the “R” dimension plus the “X” stroke (as ordered) in the extended position.

Example: Part number VIP-3-A-M-P-3.0Qx-1.25Ry-1.0-LH

In this example the Fixed “X” dimension (fully extended) equals 4.0” (3.0 “X” stroke + 1.0 “R” dim.) from the back surface of the tooling plate to the outer surface of the cover panel. If an adjustment is made to increase the “X” stroke from 3.0” to 3.125”, the “R” dimension would be automatically reduced from 1.0” to .875”.

At the bottom of each size unit dimension page is a “How To Order” chart with sample information in the data fields and page reference tabs to help guide you through the selection process. Below is a check list to get you started. If you have trouble determining any of the selections consult Stelron’s knowledgeable engineers.

1) Determine the available sizes based on the desired strokes from the “Standard Sizes & Stroke Ranges” chart on page 5 then, use the engineering information on pages 20 and 21 to more accurately size the unit by calculating the loads and capacities for your application.

2) Determine if you want an adjustable stroke or fixed stroke unit. If adjustable, select the stroke range “A” or “B” from the chart at the top of the dimensions page for the selected size unit.

3) Select the mounting position of the unit for your application from the chart on page 16.

4) Add optional mounting plates if desired.

5) Select standard cam sequences from the “Standard “X” and “Y” Cam Sequences” chart on page 5. If no standard sequences apply use the worksheets on pages 22 and 23 and consult Stelron engineers.

Specify the “R” dimension using the information below. The “R” dimension defined is a customer specified distance between the back surface of the tooling plate, in the fully retracted position, and the outer surface of the cover panel. If you have selected a fixed stroke unit simply specify the “R” dimension to suit your application needs however, if you have selected an adjustable unit the information below may prove valuable for determining the “R” dimension. This information will provide you with a better understanding as to what happens when you make an adjustment in either the “X” or “Y” stroke.

7) Select a Left Hand unit or Right Hand unit.

8) Determine if a spring type unit would be right for you application. A few factors that must be considered are speed, weight of tooling

When adjusting the “Y” axis stroke, the distance from the bottom of the tooling plate to the bottom of the unit housing

changes by the exact amount of the change in stroke. The Fixed “Y” dimension is given for each size unit on their respective dimension page.

Note: This information does not apply to the SVIP-5.

Standard Size & Stroke Ranges

Adjustment & Calibration : By referring to the example on the left it will be observed that the “X” & “Y” strokes may be

changed by repositioning the yoke pin block. This is done by loosening the clamp screw “S” and adjusting the lever screw “T” through access holes provided in the main housing. When the desired stroke is obtained retighten the clamp screw “S”. Note: The “X” & “Y” lever adjustments are identical.

It will be noted that changing the stroke does not affect the fixed extended up position of the external end plate. The termination of the “X” & “Y” strokes will always return the slide yoke position “inline” vertically & horizontally with respective lever pivot shafts.

It is recommended that orders for variable stroke units specify the “X” & “Y” strokes so that initial calibration can be performed prior to shipment

“SVIP” Vari-PakThe SVIP provides full stroke compliance in both axes thus reducing the risk of major damage to expensive tooling while improving repeatability and reducing backlash. There is no dimensional difference to the VIP unit. There is however, a minimum “R” dimension required for different length “X” strokes. The formula for determining the minimum “R” dimension is: (“X” Stroke x 0.25 + 0.5”) Note: Formula is valid for SVIP-1 through SVIP-4.

2) Static and dynamic deflection of the transfer rods (as it relates to the "r" dimension).

3) Spring loads (in the case of optional SVIP units).

Stelron application engineers can provide this additional data to ensure peak performance.

Accelerations above 1g (386 in/sec2) must be approved by Stelron.

The minimum cam angle is the first listing for each output stroke.

Most applications should be sized for a minimum of 50,000-hour life.

Each table listing has (2) ratings. The "B-10" Capacity is for calculating the life at a given speed. The Variable and Fixed Lever Capacities are the maximum allowable load on the lever mechanism.

For lesser strokes than given in the capacity tables use the minimum value shown for the respective axis.
