3 -4

3.3 SAFETY PROTECTION DEVICES OF THE EQUIPMENT

The protection devices of the equipment are divided into three categories: 1. Fixed balustrade(including ladder, maintenance steps); 2. Fixed protection shield 3. Movable shield

1) Fixed balustrade

(1) Fixed balustrade: located on the front machine of the pin-setter. The balustrade arefixed to the step of the front machine with bolts to protectworking staff from stepping into the pin-setter accidentally. (as shown in thegeneral drawing)

(2) Ladder: located at the front machine side of the pin-setter, helping the working staffclimb from the floor to the step of the front machine of the pin-setter.

(3) Maintenance step: located in front of the front machine of the pin-setter, to be usedby staff during operation, maintenance & repair. It helps the maintenance staff dotheir work without entering the lane, and consequently avoids being hit by the balls.

2) Fixed Protection Shield

(1) Protection shields on both sides of the pin-setter: located on both sides of the pin-setter, of screen structure, and can prevent the hands, the sleeves of the workingstaff or other hard objects from entering the pin-setter by mistake, which may causeinjury of the staff or damage to the machine. It also enables the staff to observe therunning of the pin-setter.

(2) Protection shield in front of the pin-setter: located at the cam control part of the frontmachine of the pin-setter, and above the sweeper. Screen shield too; and canprotect the hands, the clothes of the working staff or other hard objects from enteringthe pin-setter by mistake, which may cause injury of the staff or damage to themachine.

3 ) Movable Protection Shield

(1) Back shield protection door: a pair of doors in the middle of the back shield of thepin-lifter of the back machine of the pin-setter ( as in Drawing 3.9), with a plug-inconnector on each door. When any of the doors is opened, the plug-in connector isseparated from the safety switch, and cuts off the power supply, and the backmachine stops working, thus the working staff can do the maintenance work. Whenboth doors are closed, the plug-in connectors enter the safety switch, and the back


3 -5

machine is connected with power and starts working. In order that the doors arefirmly closed, there is a locker on the door to lock the doors. This prevents thedoors from opening suddenly when the machine is running, and avoids the stop ofnormal operation of the machine.

(2) Manual protection cover of the reducer: located on the vertical motor of the frontmachine reducer of the pin-setter. It can be pushed in or pulled out along the rail(as in Drawing 3.10).When the cover is pulled out, the plug-in connector installed on it is separated fromthe safety switch, and the motor is power off. If align the hole on the cover with theouter axle of the motor, the manual handle can be inserted into the outer axle of themotor, turn the motor axle for manual adjustment.When the cover is pushed in, the plug-in connector is inserted into the safety switch,and the power to the motor is on. The motor can run normally. Meanwhile, thehole in the cover is not in line with the outer axle of the motor, and the manual handlecan not be plugged in. This avoids the injury to the staff or the damage to themachine parts which may be caused by inserting the manual handle when the motoris running.

(3) Ball-returning machine protection door: located at the ball exit of the ball-returningmachine, including the safety door devices and the movable plate with protectiveinching switch.The safety door device opens outwards in a single direction. The balls can roll outfrom the ball-returning machine and no one can push the door open from outsideand hold his hand into the hole. This guarantees the safety of the user. Duringmaintenance & repair, the staff can turn the safety plate and cut off the power to theball-returning machine to guarantee the safety of the staff.

Note: All safety protection devices must be installed before running the machine.

4.1.2 Electric operation of Pinspotter4.1.2.1 Motors

There are 5 asynchronous induction motors in a Pinspotter. These motors operate ondifferent frequencies and voltages and may be chosen to match the local powersupply .All motors have gear reducer unit attached.

1). Front end motors

Two vertical motors are mounted in the front endof the Pinspotter and drive table and sweep.These two motors can be switched. The tablemotor runs intermittently in one direction. Thesweep motor runs in both direction .

2). Other motors

There are also three horizontal motors :● Back end motor, mounted in the back end, drrves the distributor, thecarpet and the pin wheel. This motor runs continuously.● Fasttrack motor installed in the Fasstrack in the center of each pair of Pinspotterwhich is used to send the balls from the pinspotter to the ball return runs continuously.●Ball-return motor installed in the power lift is used to drive two V wheels to raise theballs delivered by the Fasttrack to the ball rack.

4·1·2·2 Switches

1) Sweep cams

The sweep is controlled by three cams and switches:

● SA cam and switch determine the second guard position and the position of the sweep.●SB cam and switch determine the first guard position .● SC cam and switch determine the interference zone of thesweep and the table.

These switches will start-up or shut down the motorIn accordance with the position of the cams.

2) Table cam

The table is also controlled by three cams and switches.

● TA cam and switch determine the zero position.

● TB cam and switch determine theinterference zone of the table and thesweep.

● TC cam and switch start-up the operation ofthe sweep.

These switches will start-up or shut down themotor in accordance with the position of thecams.

4.1.2.3 Other switches:

1) Off-spot switch

This switch closes when the table touches a pin that moved from.It is used to preventdamages to the machine.

2) Bin switch

This switch closes when pin # 9 (the last pin filled in) is fed into the bin. The purposeis to make the machine to spot pins only bin is full.

4.1.2.4 Motors and gearboxes

4.2.4. Operation and adjustment of the distributor

4.2.4.1 Operation of the distributor

The distributor transfers the pins from the pin elevator to the bin assembly. Thedistributor is driven by an adjustable clutch through its various positions. The nyloncam gear has two functions:

a. At the outside of the gear there is a cam that moves the distributor left and right tothe various bin locations.

b. The inside of the gear has a cam that controls the telescoping action of the frontportion of the distributor. Springs keep the cam followers against the cams.

4.2.4.2 Distributor belt replacement

1. Remove the Belt Tightener Spring.

2. Locate the belt lacing and remove the belt pin. Then the belt can be removedfrom the distributor, The finished length of belt is from 2972mm to 2978 mm.

3. To increase the belt tension, cut off a little from one end of the belt, belt tightenerspring length will increase one-half of the amount of the cut off of the belt.

4. Mount the new belt clip in the belt, then mount it into distributor and insert thepivot of belt.

5. Reinstall the Belt Tigthener Spring.

4.2.4.4 Replacement of the distributor

1.To replace the distributor drive assembly, follow the removal procedure in thereverse order.

2.Check if the marks of the pinion and nylon gear are in correct alignment.

3.Retationg the spring’s clip to set the clutch spring tension.Turn on the power of the machine and start feeding.(1) If the spring tension is not strong enough, the distributor will stall between the7th and 10th position. Increase the tension to correct the problem.(2) If too much tension is applied, it will cause stalling of the distributor or failure to

index.

4.When the distributor is at the #1 pin feed position, the space between distributororiental pan and pin elevator should be around 6.5 mm. If it is necessary to makeadjustment, loosen the oriental pan mount bolt and position accordingly.

4.2.4.5. Operation of nylon cam gearThe cam has a timing mark along its outer edge at the base of a valley between twoteeth. This bump and a notched tooth on the pinion gear must be aligned for propertiming. See previous section for instructions on how to realign the cam and piniongear. The outer face of the large cam is marked for the feed position of the pins,which are attained as the outer cam follower traces the path laid out by the camsections.

The inside of the cam controls the telescoping of the distributor using cam sectionsand a cam follower in a manner similar to the operation described in the previousparagraph. During operation, the distributor is forced inward by the action of the innercam follower, and telescopes outward because of a combination of return springtension and a moving belt’s tendency to straighten out whenever the cam follower’slinkage allows it to do so.

4.2.4.7 Distributor roller adjustments

1. Start distributor at 1# bin position, telescope the distributor to its shortest length.

2. Position front lower eccentric roller down to the lowest position to obtain themaximum distance between roller and carriage tube (refer to Figure 4.2.31).

3. Bring the top rear eccentric roller down until there is a noticeable drag against thecarriage tube when you turn the roller. (It will influence the extension of the distributorto have a too big friction.)

4. Adjust upper front eccentric roller until trip rod tube and carriage tubes are parallelto each other.

5. Adjust lower front eccentric roller and make it just touch the carriage tube.

6. Recheck the rear eccentric roller to ensure it is not exerting too much pressureagainst the carriage tube. Adjust as necessary.

7. Adjust the steel cable to obtain equal clearance between the nylon roller and triprod tube. The clearance between the nylon roller and the trip rod tube should beapproximately 1.5 mm in all position of the distributor. (Refer to Figure # 4.2.31)

4.2.5 Shuttle and Bin operation and adjustments:

4.2.5.1. Operation of Shuttle and Bin:

The shuttle located below the bin, holds pins in the bin until a new reset required.When the shuttle cam follower travels to the low position of the shuttle cam, theshuttle momentarily moves forward to allow a set of pins to drop through from the binto spotting cups.

The bin assembly will stores two sets of pins.

4.2.5.2 Shuttle and Bin adjustment

Note: Adjustment would be made with no pins in bin.

1.There should be approximately 43.5 mm between the back channel to the leadingedge of the shuttle assembly measured at the center. To make this adjustment,loosen lock nut on connecting rod and adjust accordingly, tighten the jam nut.

2. The Shuttle assembly should be centered directly under the bins, adjustment isaccomplished by reposition spring.

3.The distance from the rear channel of the bins to the shuttle assembly should be22mm, adjust the length of the two side rods to obtain this dimension.

Note: The threads on rods on both sides of the shuttle are right handed.So, to make the adjustments, one of the ends must be removed.
