Operation and Cycle

Allied Bowling-Control-Box Actions That Start a Machine Cycle Depending on the control-box that is used any of the following occurrences will cycle the pinsetter 1 I Pushing the reset buttons on the control-box 2 I Switch “ON” by the main switch ore scoring 3 I Pushing the reset buttons on the ball rack 4 I A bowling ball knocking over one or more pins 5 I The second ball in a frame breaking the photo cell beam and hit pins. Otherwise it goes in the first ball 6 I Sending a “RESET-Signal” over the RS232

Description of Cycles During Bowling Strike Approximately three seconds after the first pin falls, all ten pins are raised to the full up position and reset.

First Ball Thrown is a Gutter Ball The machine will receive and remember the ball detect signal.

There is no machine activity and after approximately five seconds the machine is ready for the second ball.

First Ball Thrown Part of Pins Knocked Down Approximately three seconds after the first pin is knocked over all ten pins will be raised. Those that were left standing will be re-spotted.

>> PAGE 7 // 28

After Second Ball of Frame is Thrown Approximately three seconds after receiving a ball detect signal the machine will go into the first.

Pinsetter Switch Functions

Allied Bowling-Control-Box Disentangle Switch If the cord of two or more pins become tangled as they are being raised, the tension lever assembly will rotate and actuate the disentangle switch. Reference Figure 3-1

Figure 3-1 Disentangle Switch Activation

When the disentangle switch is actuated and the pins are not fully up, the machine will stop raising the pins and start shaking them up and down.

This shaking action will continue until the pins are no longer tangled or a service person turns off the machine and manually corrects the problem. Reference Figure 3-2

Pinsetter Switch Functions Pin Setting Cam The pin setting cam`s function is to slow down the speed at which the pins are moving as they are being set on first ball or re-spotted on second ball. There is one of these cams on each side of the frame at the pit end of the pinsetter. This cam changes the path of the string during the down motion which slows the travel of the pins. Reference Figure 3-6.

Adjustments String Tension Adjustments The string tension adjustments can only be made after the pins have been secured to the strings. This adjustment can effect all other adjustments.

1 I Turn the pinsetter power on and move the pins up switch until pins are pulled up in the centering cone.

2 I If pins won`t come into centering cone turn off power to the machine and got to Step 3.

3 I Slide the string spool to the left away from locking pin. Reference Figure 5-1.

Figure 5-1 String Tension Adjustments 1 I Pinsetter Cycled to Pins Up Position 2 I Limiter Bar 3 I Turns As Arrow Shows to Increase Extension 4 I Turns As Arrow Shows to Decrease Extension 5 I Away From Locking Pin 6 I Toward Locking Pin 7 I Locking Pin

4 I Rotate the spool as required to obtain a gap of 1mm to 5mm between the limiter bar and the tension lever. Reference Figure 5-1.

>> PAGE 14 // 28

Note: Rotating the spool as arrow (4) shows will reduce the tension. Rotating the spool as arrow (3) shows will increase the tension 5 I When the proper gap has been obtained, move the spool to the right and rotate it as required to align one of its holes with the locking pin. Reference Figure 5-1.

6 I Turn “pins up� switch to the off position.

Adjustments String Brake Adjustments 1 I With the pinsetter power on, knock over some pins. The machine will cycle and should keep the knocked over pins in the up position.

2 I Check the amount that the pin cam move up by pulling up on the string until the pin bottoms out. The amount of travel is to be 80mm ± 20mm. Reference Figure 5-2.

Figure 5-2 String Brake Adjustment

>> PAGE 15 // 28

3 I If the travel is greater than 100mm move the cam switch brake toward “C”. If it is less then 60mm, move the cam switch brake toward “D”. Reference Figure 5-2.

Adjustments Pin Slow Setting Adjustments 1 I With the pinsetter turned on, knock over some pins. When the string wagon comes all the was forward, turn off the power to the machine. Reference Figure 5-3.

Figure 5-3 Slow Setting Adjustment

2 I Using the large drive pulley, manually rotate the machine in reverse until the roller on the string wagon just touches the delay cam. Reference Figure 5-3.

3 I With the machine at this position, measure the distance from the bottom of pins 1, 2 and 3 to the pin deck. The distance should be 60mm Âą 20mm. Measure the distance between the bottom of the remaining pins, 4 through 10. The distance should be 80mm Âą 20mm.

Reference Figure 5-3.

4 I If the dimensions are incorrect, move the delay cams forward or backward to obtain the required dimension. Reference Figure 5-3.

>> PAGE 16 // 28

Note: The fore and aft position of the cams must be the same on both sides of the machine.

Adjustments Fallen Pin Detection Adjustments The detection sensitivity level for pin fall can be adjusted in a range of 1 to 15. There is a sensitivity level adjusting gear for each of 10 pins. They are located at the front of the machine just above the string spools. Reference Figure 5-4.

>> PAGE 17 // 28

The recommended sensitivity level setting is 10. The gears are marked every fifth tooth with numbers 1, 5, 10, and 15.

By 1 the pin are very fast detected by 15 very slow.

Maintenance / Service Pin Strings Important: When performing any maintenance, make sure the main power is turned off and / or the power plug has been disconnected.

Pin String Inspection and Repairing Worn String

NOTE: Strings should be inspected at least twice a month.

Check the strings for wear paying particular attention to the area the head of the pin. If worn, remove the section of string by performing the following steps.

1 I If the strings are worn or frayed, cut the string off above the worn area.

2 I Using a match or a lighter, melt the end of the string which will be inserted into the head of the pin. While the string is still hot, taper the end so it easily be threaded through the holes in the head of the pin.

Important: Wear gloves and use a rag to taper the melted string end to avoid burning your hands.

3 I Thread the string through the head of the pin and tie a knot in the end of the string. Leave approximately ½” (12,7 mm) of string extended beyond the end of the knot. Reference Figure 6-1.

>> PAGE 18 // 28

Figure 6-1Thread String Through Pin

1 I Thread String Into Head of Pin 2 I The Knot In String Leaving Excess of ½” (12 mm) 4 I Pull the string back through the pin until the knot bottoms out in the pin. Reference Figure 6-1.

5 I Adjust the string tension for any pin where the string has been cut, and pin installed.

Maintenance / Service To control the way the pins are lowered to the pin deck, a limiting bar is installed between the pinsetter side frames. The strings for pins 4 through 10 go over the limiting bar.

The strings for pins 1 through 3 do not go over the limiting bar. Reference Figure 6-2.

>> PAGE 19 // 28

Figure 6-2 String Paths

Maintenance / Service New String Installation 1 I Cycle the pinsetter to first ball with ten pins on the pin deck.

Turn off the pinsetters main power switch and unplug the power cord.

2 I Cut the string if any pin being replaced just above its head. Reference Figure 6-3.

>> PAGE 20 // 28

Figure 6-3 Restring Machine

3 I From a spool of replacement string cut off a piece 16`5� (5m) long for each pin having its string replaced.

4 I Melt the cut end of the old string and one end of the new string. While the string ends are still hot, press them together and hold until they cool and form a joint. Cover the joint with electrical tape to increase its strength. Reference Figure 6-3.

5 I Thread the new string up to the spool by carefully pulling up the old string until the new string is at the spool. Remove the tape at the joint between the old and the new string. Cut off and discard the old string. Reference Figure 6-3.

Maintenance / Service New String Installation 6 I Remove the old string from the spool. Tie a knot in the end of the new string. Slide the knot through the key slot in the spool shaft and secure it. Reference Figure 6-3.

7 I Secure the string to the pin following the procedure detailed for Repairing Worn String.

8 I Wind the extra string onto the spool by rotating the spool as arrow (3) shows in Figure 5-1.

9 I Adjust the spring tension for each new string, following the String Tension Adjustment.

Lubrication Routinely

>> PAGE 21 // 28

Regular lubrication of the machine is necessary for a long machine life and good performance. The interval should be appropriate for the amount the machine is used. The more the machine is used, the more frequently it should be serviced.

• Every moving machine part should be lubricated from time to time.

• Every working part such as drive gears and drive chains, require more maintenance than low load parts.

• For large parts drive gears and chains sprockets grease is the best lubricant • For small parts, (small parts) oil should be used.

Maintenance / Service Lubrication Routinely Quarterly (Every 3 Months) • Apply grease to chain with a paint brush to lubricate chain`s exterior. Reference Figure 6-4.

• Oil chain with special chain sprays (foam). This oil will penetrate chain links to lubricate the chain interior. Reference Figure 6-4.

• Apply chain spray (foam) to the pivot point where the string wagon is attached to the chain.

Reference Figure 6-4.
