Pressure Bar (Rubber) Replacement; Anti-Jam Adjustment - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S14 Operation Manuals

4.11Pressure Bar (Rubber) Replacement

Located along the inside of the pressure bar is a strip of rubber, held on the pressure bar by a channel,
pressing on the edges of the rubber. The rubber compresses against the front (gripper) plate holding the
bag in place during sealing and bag tear-off. If the rubber becomes brittle, torn, gouged or otherwise
worn, it should be replaced to assure strong seals.
To replace the pressure bar rubber, simply pull one end of the rubber from the channel. The rubber will
come out of the channel quickly and easily. To install a fresh piece of rubber, press one edge of the rubber
into the channel, then the other edge. Work the rubber into the channel in small increments along the
length of the channel. See Figure 4-5 and 4-6. If you used Teflon tape to cover the surface of the rubber,
place the Teflon on the rubber along its length. If the Teflon extends beyond the rubber, cut off the
excess.
NOTE: Teflon may be added to the pressure bar rubber if the bag sticks to the rubber after loading and
sealing. The bag may stick to the rubber if the product and bag are lightweight and if the rubber is dirty.
NOTE: Frequently clean the rubber with alcohol to remove buildup of dirt or other contaminants.

4.12 Anti-Jam Adjustment

The anti-jam device is designed to protect the T-1000-S14 from damage when an obstruction is
encountered in the seal area (area between the pressure bar and front [gripper] plate). If properly adjusted,
the pressure bar will retract if an obstruction is encountered in the seal area. The pressure bar houses
springs that cause the rubber and holder to compress. When the rubber holder compresses, a sensor is
activated, causing the pressure bar to retract. The sensor is defeated when the pressure bar is
approximately 1/8" from the gripper plate. See Figure 4-7. The anti-jam device can quickly be tested
while the T-1000-S14 is operating using care, but it should be thoroughly tested by disconnecting air and
power and removing covers.
To quickly test the anti-jam device, place a 3/8" diameter flexible poly tube against the front (gripper)
plate perpendicular to the seal bar opening. Press the foot switch allowing the pressure bar to compress
the poly tube against the front plate. If the pressure bar does not immediately retract and place the T-
1000-S14 in the STOP mode, the anti-jam device is not properly adjusted. Test the anti-jam device along
the entire length of the pressure bar using the 3/8" poly tubing as a test device.
CAUTION: To avoid personal injury, do not place fingers or hands into the seal area of the
T-1000-S14 while power is ON or air is attached. Do not test the anti-jam device with hands or
fingers. Ensure the poly tube that is used for testing is long enough to keep fingers or hands away
from the seal area of the T-1000-S14.
To thoroughly test and adjust the anti-jam device, you must first turn the power to the OFF position,
disconnect the air line from the T-1000-S14 and remove the top and left side cover. With the covers
removed and air disconnected, turn the power to the ON position.
To test the pressure bar sensor, locate the "X4" LED on the PLC Board and ensure the light is illuminated
(ON). Then, compress the rubber and holder into the pressure bar (nylon holder). As soon as the rubber is
pressed into the nylon holder, the "X4" LED should turn OFF. The LED should remain off while the
rubber is held compressed into the nylon holder. If the "X4" LED shuts off while the rubber bar is pressed
into the nylon holder, the pressure bar sensor is functioning properly.
To test the anti-jam override sensor, locate the "X7" LED on the PLC board and ensure that the light is
off. Then, standing in front of the T-1000-S14, push the pressure bar slowly towards the front plate,
keeping hands and fingers out of the seal area. While pushing the pressure bar towards the front plate, do
not compress the rubber into the nylon holder or touch the round nuts on the pressure bar. See Figure 4-7.
