Short Seam Automat 2112-4 Working Instructions

B.2.1 Sewing functions of the machine

The short seam automat 2112-4 can perform three different, automated sewing functions:

• Crimping over of the pocket edge and sewing the pokket edge to a pocket bag.

• Clipping and crimping over of the left slash selvage with subsequent sewing of the slash selvage to the left trousers component.

• Sewing the slash selvage to the right trousers component.

B.2.2 Pocket edge function

The machine cycle "Sewing on pocket edge" is performed as follows:

• Pocket edge and pocket bag are positioned manually.

• The pocket edge is crimped over and picked up.

• The folder transports the pocket edge to the pocket bag.

• The transport system automatically transports the pokket edge and the pocket bag to the sewing head where they are tucked.

• The finished piece is transported to the stacking table by the stacking system and put down.

Fig. 2

Fig. 3

B.2.3 Lining up pocket edge/pocket bag

Depending on how the pocket edge and the pocket bag are to be sewn to one another, the two pieces must be aligned at the line-up positions. The exact line-up position of the edge to the bag can be marked at the working plate or at the pick-up plate using tape or pen. Please note that the pocket bag must be lined up within the operating range of the pocket bag clamp (Fig. 3, 4).

Handwheel for stitch width, Fig. 2:

The handwheel 1 is used to set the correct stitch width for the pocket edge. The stitch width depends on the thickness of the fabric. The thicker the fabric, the larger the stitch width.

Line-up position for pocket edge, Fig. 3:

The pocket edge 1 is lined up at the stop rail 3 of the pick-up plate. The exact alignment to the pocket bag is marked by a marking 2 at the pick-up plate.

Folder

The folder 6 moves to the left with the pocket edge, is lowered and puts the pocket edge onto the pocket bag.

Pocket bag clamp

The pocket bag clamp 7 fixes the pocket bag to the working plate until the main clamp picks up the sewing pieces and transports them to the sewing head. The pocket bag clamp closes while the folder moves to the left.

Main clamp

The main clamp 8 moves to the inserting station and picks up the sewing pieces. The folder moves back up to its start position. The main clamp pushes the sewing piece on the working plate from the inserting station to the sewing head.

Fig. 5

Sewing head

The sewing head 5 performs only the functions sewing stitch and thread cutting. All other functions, such as seam length or determining the beginning and the end of the seam, are acquired by the sensor system and controlled by the program control unit in accordance with the set values. The thread stock and the thread supply of the sewing head are monitored by sensors (top thread monitor and spool residual thread monitor). The thread holder can hold two thread spools.

Transport stamp

After tucking, the sewing piece is blown even and transferred by the transport stamp 3 to the stacker.

Stacker

The stacker consists of a sliding table 4 and a lift table 1. The sewing pieces are put down on the sliding table of the stacker. The sliding table then moves backward, and the sewing pieces 2 fall onto the lift table where they are stacked. The lift table is lowered automatically (photocell control) or is lowered in preset steps in accordance with the input numbers.

B.3.1 Safety instructions for operation

Beisler Automated Sewing Equipment

Machine operation:

WARNING - Machine operation intervention!

The machine is driven by electric motors and by compressed air. Any attempt to stop the moving parts of the machine or to tamper with the movements by hand may cause severe injuries.

• Keep hands away from machine during machine operation!

• During the sewing process, keep hands away from the operating range of the needle!

• If a failure is encountered during machine operation, press the program stop switch immediately!

Clothing:

CAUTION - Unsuited work clothing!

The moving parts of the machine may catch and draw in loose clothing which may cause severe injuries.

• When operating the machine, do not wear wide or open clothing!

• Make sure that sleeves are tight-fitting and properly closed!

Handling the guide laser:

CAUTION - Damage of the retina!

If the eye is directed toward the laser beam for some time, the retina may be damaged.

• Do not look directly into the laser beam!

• Do not direct laser beam into eyes!

CAUTION - Laser beam change!

An optical change of the laser beam may increase its luminous intensity and cause eye injuries.

• If the direction of the laser beam is changed, if the laser beam is misadjusted or if the laser optics are damaged, turn the machine off and shut it down.

• Do not allow optical equipment (burning glasses or lenses) to interfere with the laser beam path.

B.3.2 Preparing the machine

Prior to the production start, check the supply connections, connect the machine to the compressed air and power supply systems and prepare the sewing head.

1. Insert needle, pass top thread through needle and insert spool for bottom thread into sewing head (see working instructions of sewing head manufacturer or supplier).

2. Fig.17: Connect machine to compressed air supply by inserting the plug-in connector 2 of the compressed air supply hose into the compressed air receptacle in the operating room. The pressure of the compressed air is reduced to the required operating pressure of 6 bar by a pressure reducer 1. Check manometer to see if the correct operating pressure is set. The pressure reducer is installed at the side mounting wall of the worktable.

3. Connect machine to power supply system.

WARNING - Electric shock!

Fig. 17

Contact with current-carrying components may cause a lethal electric shock. Check plug and cable before connecting machine to power supply system.

• Do not use damaged plugs, sockets or cables to connect the machine to the power supply system!

• The machine is connected to a power source of 230 V ±10 % at 50/60 Hz.

• Before connecting the machine to the power supply system, check to see if the ratings of the power supply system in the operating room correspond with the ratings on the nameplate at the rear of the machine.

• If the ratings for voltage (V) and maximum current (A) do not match, the machine must not be connected.

• Insert the grounding plug into a properly grounded and fused power socket.

B.3.3 Selecting the sewing program

After the machine has been turned on and the control program has been activated, the sewing program that had been selected last is set. Sewing programs 1 are stored in the memory (M). The program control memory can store up to 50 sewing programs (M 01-M 50). Fig. 18: For each sewing program, up to six seam numbers2 (01, 02, 03, 04, 05) can be assigned.

The program control of the machine is equipped at the factory with two standard programs:

• Sewing program M 01 with five different seams for crimping over and tucking the pocket edge (see Section D, Programming Instructions),

• Sewing program M 02 with one seam each for tucking the left slash selvage (12) and the right slash selvage (11) on the trousers component. In addition, this sewing program is programmed for a test seam (13) that is restricted to two functions:

• Clamp movement from the insertion station to the sewing head,

• Starting/ending the complete sewing process.

The test seam is used for checking the clamp transport and the sewing process when the machine is set up.
