Section 1: OperationsOverview

This manual is designed to help you prepare for the service, repair and preven-tive maintenance of the GS Certified Pre-Owned Pinsetters in a safe andefficient manner. Prior to working on one of these pinsetters, you should readthe Safety Guidelines located at the beginning of the manual.

This manual also provides troubleshooting guidelines that will help reducedowntime and can be used to provide years of reliable operation of yourpinsetters.


Pinsetter OrientationWhenever any position or motion is described in the text of this manual such asright, left, forward or rearward, the description is as if viewed from the foul line.Clockwise (CW), counterclockwise (CCW), is determined while looking at thepinsetter from the left side or top. Refer to Figure 1-1.

Pinsetter DescriptionThe GS Certified Pre-Owned Pinsetter consist of eight subassemblies:

Ball PitBall AcceleratorPin ElevatorDistributorSetting TableSweep WagonDrive FrameElectronic Control

Ball Pit

The primary purpose of this area is to handle the initial impact of the pins andball and to direct them to the proper part of the machine.

The ball pit is made up of the following components.

1. Ball Cushion - Stops the ball and guides it into the ball accelerator. Refer toFigure 1-2.

2. Pin Curtain - Stops the rearward movement of the pins and creates a blackbackground behind the pin decks. Refer to Figure 1-2.

3. Transport Band - Brings the pins to the elevator assembly and holds the ballagainst the ball cushion while it is guided to the accelerator. Refer toFigure 1-3.

Ball Accelerator

Mounted between the two pinsetters is a ball accelerator that returns balls to thebowler from either lane. The ball enters from the transport band through a balldoor and onto a track. A large flat belt mounted on two drums grips the ball andpropels it forward to the ball lift. See Figure 1-4. Power to run this belt isfurnished by a three phase motor incorporated into the rear drum.

To prevent balls from opposite lanes from entering the accelerator at the sametime, the accelerator has ball doors and ball door locking assemblies. See Figure1-5. A button on the door must be pressed to allow the door to open. Thisprevents a pin from entering the accelerator as it is being carried rearward by thetransport band. A ball door locking solenoid is energized for three seconds afterball detection to prevent pins from accidentally opening the door as they fall offthe pin deck. Once a door is open, the door for the other lane is blocked fromopening.

Pin Elevator

The pin elevator receives the pins from the transport band and raises them up tothe distributor. The elevator has 14 shovels that lift the pins, one per shovel.See Figure 1-6. The shovels are moved by two parallel chains that are beltdriven by the distributor motor. At the bottom of the elevator two pin feeddeflectors guide the pins into the elevator. As the shovels lift the pins, pindeflectors position the pins in the middle of the shovel. If more than one pin ison the shovel, this deflecting action will knock one of the pins off the shovel.Halfway up the right side of the elevator frame is an ejector. This will gentlywiggle each shovel to knock off any pin that is not securely held by the shovel.

A pair of pin centering wedges position the pin to the center of the shovel. Thisassures proper pin alignment when entering the shark assembly.

At the top of the elevator, a shovel guide on the right side tips the shovel toallow the pin to roll out onto the pin guide wedges of the shark assembly.

Distributor

The distributor moves the pins from the elevator and places them in position sothe setting table can receive them. The distributor consists of a shark assembly,four pin feed lanes, two cross over lanes, 10 pin stations, and right/left over-flow chutes. See Figure 1-7.

The shark switch assembly’s pin guide wedges turn the pin so that it will bepositioned onto the distributor round belts bottom first.

A pincount switch on the top of the elevator counts pins leaving the elevator.See Figure 1-8. The electronics then sends a signal to the shark solenoid tocontrol the position of the shark fin while feeding pins to the distributor lanes.

The pins move down the distributor lanes until an empty pin station is found.See Figure 1-9. At the empty pin station, an ejector flap sticking between thetwo round belts will cause the pin to fall onto the pin station’s retaining bow.This will lower the ejector flap and allow any other pins traveling along thedistributor lane, to move onto the next available pin station. The pin is held inthe pin station until the setting table is ready to receive that pin. The retainingbow will release the pin when the pin holder’s gripper pushes up on the pinrelease lever.

There are three styles of pin stations:• Left-hand for pins 2, 3, 4, and 9• Right-hand for pins 1, 5, 6• Short retaining bow flap - pins 7 and 10

Any pin that does not find an empty pin station is returned to the transport bandthrough the overflow chute at the end of each outside distributor lane. SeeFigure 1-10. If no bowler activity occurs within 45 seconds, the distributormotor will shut off to save energy and reduce wear on the pins and pinsetter.

Setting Table

The setting table is a multipurpose assembly. It must:

A. Detect for standing pins after a ball has been rolled. Figure 1-11.B. Close the spotting tongs and pick up the pins standing on the lane to

allow the sweep to clear the dead wood. Figure 1-12.C. Receive pins from the distributor and set them on the lane for a new

frame. Figure 1-13.


Figure 1-11. Detecting Pins.

Figure 1-12. Spotting Tongs Closed - Picking Up Pins.


Figure 1-13. Setting New Pins.

The setting table contains ten pin holders that are mounted on four swing shafts.The pin holders are held in the horizontal position by a latch assembly located atthe back left side of the setting table. The holders remain horizontal when thesetting table is loading pins, waiting for a ball, or when it is detecting pins. Theonly time the ten pin holders are rotated to a vertical position is when the tablelowers all the way down to set new pins onto the lane surface.

Each pin holder has a switch that serves two purpose.

1. Detect standing pins2. Detect when a pin is loaded in the pin holder


The GS machine is able to detect standing pins with the pin holders loaded orwith empty pin holders. By checking whether the switch has changed statusduring pin detection. Refer to Figures 1-14 .

When the table must go all the way down to set new pins, the left square shaft isrotated by a stroke limiter solenoid to release the latch. A large spring mountedon the front swing shaft pulls the pin holders into the vertical position. Refer toFigure 1-16.

After the pins have been set, a roller on the rear shaft will press against the TS1Jam Assembly Arm to overpower the spring on the front swing shaft and rotatethe pin holders back to the horizontal position. Refer to Figure 1-17. The latchwill keep them in this position until the stroke limiter solenoid is energizedagain.

On the right hand side of the table is another square shaft. This square shaftrotates when the spotting tong solenoid energizes, engaging the gear clutch withthe table drive. This square shaft uses a series of gears and toothed racks todrive all ten spotting tongs closed when the table motor is turning counterclock-wise. The shaft turns in the opposite rotation reopening the tongs when the tablemotor is turning clockwise. Refer to Figure 1-18.

The bottom of the setting table has a 9" (229 mm) round cutout for each pinlocation. During bowling the pin may be moved off spot but still within thecutout when the table lowers during detection. The spotting tongs are designedto allow them to close on the pin regardless of the position of the pin within theopening. Refer to Figure 1-19.

When the tongs are closed, the connecting links are driven over center to lockthe tongs closed and prevent pins from dropping from the table when raised forclearing deadwood. Refer to Figure 1-20.

There are two types of spotting tongs:

At each side of the setting table is a table rack tube. These are used for guidingthe table as it raises and lowers. The right-hand tube has a chain attached to itthat routes over a sprocket mounted on the top of the guide tower to a crank armattached the table drive shaft. Refer to Figure 1-21.


The left-hand table rack tube has a “T” stop on the top of it. It stops the lower-ing of the setting table at the pin detection height when it comes in contact withthe stroke limiter plate. The plate is pulled out of the path of the “T” stop by thestroke limiter solenoid when the table is to be lowered all the way down to thenew pin setting height. Refer to Figure 1-22.

Sweep Wagon

The sweep wagon assembly has three functions:

1. Upon ball detection or manual triggering (SET or RESET), the sweep islowered immediately to prevent pins from rolling forward on the lane.

2. To guard the table as it lowers to detect and set new pins.

3. To sweep any pins that are no longer needed on the pin deck.

The sweep consists of four major components.

1. Sweep motor and drive gear

2. Sweep release assembly

3. Sweep attenuator/shock assembly

4. Sweep wagon


The sweep wagon is held up by the sweep release assembly. To lowerthe sweep wagon, the sweep release assembly’s solenoid pulls the swinglever rearward, allowing the tipper to rotate and drop the sweep wagon.A sweep attenuator, along with its hydraulic shock absorber, slows thedropping motion. When the sweep is in the guarding position, functionswitch “G” is actuated by the attenuator. Refer to Figures 1-23 and 1-24.

Figure 1-24. Sweep Motion.

Once the sweep is down in the guarding position, the sweep motor turns thesweep shaft clockwise. This rotates the sweep crank arms and drives the sweepshaft rearward then forward. The six guide rollers mounted on the sweepwagon, assure that the wagon rolls smoothly and squarely in its sweep path.When the cam on the right side crank arm activates the Sweep Motor (SM)switch, the sweep motor shuts off and its internal brake engages to prevent themotor from coasting. This allows the sweep to be stopped exactly at the fullyforward position. Refer to Figure 1-25.

Figure 1-25. SM Switch Closed - Sweep Forward.

Near the end of the pinsetter cycle, the table motor and sweep release assemblywork together with a pivot link to raise the sweep. During a pinsetter cycle, thetable motor runs twice. The first time it runs counterclockwise. During thistime it will be unable to raise the sweep, because of the position of the releasechain and sweep release assembly. During the second half of the cycle, the tablemotor will run clockwise. This rotation positions the tipper on the sweeprelease arm under the tipper roller on the sweep wagon lifting the sweep alongwith the table.

The tipper can only come in contact with the roller when the table motor isturning clockwise. Refer to Figures 1-26 and 1-27.

Drive Frame

The left drive frame assembly consists of the three pinsetter motors along withtheir drive systems and the stroke limiter assembly. See Figure 1-28.

The front motor is the distributor motor. It is a 1/2 HP motor without an internalbrake, that uses a double pulley system to drive the front distributor shaft, all thedistributor belts, the shark assembly, the elevator and the transport band.


The center motor is the sweep motor. Its function is to drive the sweep rearwardand forward. This 1/4 HP motor has an internal brake that stops the sweep inthe forward position and prevents coasting when power is turned off.

The rear motor is the table motor. Its main purpose is to raise and lower thesetting table. This motor is the only one on the machine that turns both clock-wise and counterclockwise. It also drives spotting tongs open and closed and itraises the sweep wagon at the end of a cycle. The 1/2 HP motor has an internalbrake that locks the motor shaft when the motor is turned off.

The stroke limiter assembly determines whether the table lowers to the detectingheight or the new pin setting height. It consists of a stroke limiter plate, ahydraulic shock absorber, a solenoid and a square shaft. The plate and shockabsorber slows the table as it lowers for a short stroke to detect or respot pins.A solenoid pulls the stroke limiter plate out of the path of the “T” stop located atthe top of the left-hand table rack so the table can lower fully to the new pinsetting height. It also rotates the left-hand square shaft to unlatch the swingshafts allowing the pin holders to rotate vertical so new pins can be set on thelane.
