Glove Leak Tester – Common Failures and Causes of Equipment

1. Common Head Failures

1.1 Automatic stoppage of a machine head

Reason 1: A higher failure rate of products or glove operation by employees leads to a higher failure rate; thus, rejecting the same machine head many times in a row occurs rather than a problem with the equipment.
Solution: The operator clicks the ‘Alarm Initialisation ’button on the function setting interface to release the alarm. The machine head starts to operate normally, and continuous rejecting no longer occurs (see the relevant contents of the operation manual for details).

Cause 2: Air leakage from the machine head.
Solution: After the operation of Cause 1 solution, the machine head stops again due to continuous rejecting, which means that the clamps or related air leakage, four
possible causes of air leakage of the clamps are air leakage from the small cylinder, air leakage from the check valve of the small cylinder, air leakage from the internal air pipe of the machine head, and broken sealing ring of the clamps, the operator detects and finds out the leaking components, and replaces the leaking components with new ones.

Reason 3: Air leakage from the butt joint male head.
Solution: Replace the male butt joint with a new one (as shown in Figure 1.1.1).

1.2. Gloves don’t deflate.

Cause 1: Head solenoid valve failure.
Solution: Replace the solenoid valve (as shown in Figure 1.2.1).

Cause 2: The Circuit conductive wheel does not conduct electricity.
Solution: Repair the conductive wheel circuit or replace the wheel with a new one (Figure 1.2.2).

Reason 3: The fixed conductive guide is disconnected.

Solution: The fuse of the conductive rail in the electric control cabinet is blown;
replace the fuse and repair the circuit of the conductive rail (as shown in Fig. 1.2.3 and Fig. 1.2.4).

1.3. Inconsistency between head number and test data display

Solution: If the alarm interface indicates that the head number is incorrect, turn the device over for one revolution, then the detection head number can be initialized automatically.

2.. Common Fuselage Failures

2.1 Fuselage rattles

Cause 1: Foreign matter at the track. Solution: Remove the foreign matter. Cause 2: Other reasons.
Solution: Find out if there is any other reason for the stationary part of the fuselage and the moving part of the head to come into contact with each other, and if so, exclude it in time.

3. Common Air Circuit Failures

3.1 Low air pressure

Cause 1: The main valve of the air circuit is not opened.
Solution: Open the main valve.

Cause 2: The air line is blocked or broken.
Solution: Repair the main airline.

4. Reciprocating mechanism common failure

4.1. Misalignment of the butt connector on the head and the butt connector on the guide rod cylinder.

Failure 1: The pair of connectors corresponding to one of the guide rod cylinders is misaligned.

Solution: This may be caused by a loose rod between the cylinders. Check the connecting rods between the cylinders (indicated by the arrows in Fig. 4.1.1) and tighten them after adjusting their position if they are loose.

Fig. 4.1.1-Check the connecting rods between the cylinders

Failure 2: all pairs of connectors are misaligned at the same time.

Solution 1: This may be caused by a loose or damaged, driven roller bearing. Check the driven roller bearing (arrowed in Fig. 4.1.2). If it is loose, re-tighten it; if it is damaged, replace it with a new one. If there is no problem here, refer to solution 2.

Fig. 4.1.2-check the driven roller bearing

Solution 2: This situation may be caused by the belt jumping teeth or loosening of the large synchronous pulley of the reciprocating mechanism, and it is necessary to readjust the phase of the reciprocating mechanism. Loosen the four screws and the screw in the middle of the arrow in Fig. 4.1.3, remove the upper layer of the middle tensioning sleeve, loosen the middle layer of the sleeve, and then rotate the cam to align the positioning nylon sleeve with the positioning block on the head, and then re-tighten the tensioning sleeve and the loosened screws.

After the adjustment is completed, drive the car to the normal production speed and check whether the positioning nylon sleeve and the positioning block on the machine head are correct; if there is any deviation, fine-tune it again until they are correct under average production speed. (Note: Under average production speed, the position of the positioning nylon sleeve should be about 2mm ahead of the positioning block on the machine head.)

5. Other faults

If there are faults in other places, you can solve them according to the touch screen prompts, and if you can’t find the reason in time, you can consult our company.
