Page 6-3

Operating manual Automatic single head serging unit 1220/4

The production cycle of the machine is divided into several sections:

1. The operator inserts a trouser part from the right side (see white arrow in Pict. 6) under contour guiding (C) and photo cell (B).

2. After photo cell (B) switched dark, the sewing process starts (needle Pos. (A) in Pict. 6); the contour guiding will be lowered.

3. The trouser part will be sewed.

4. After the photo cell (B) switches light, the seam will be ended and the stamp comes down.

5. The contour guiding drives up.

6. The stacker clamp advances to the front.

7. The stamp drives up.

8. The trouser part is stacked with an air-blow.

6.2.2 Program operation

The machine is operated with programs, which are stored in the memory and can be opened by the operator. He can choose from several possibilities:

 he can select an existing program  he can change an existing program  he can create and adjust a new program

All possibilities will be explained in the following.

Page 6-4 © Beisler GmbH, Hösbach

Chapter 6: Operation

6.2.3 Select a program

In the daily production process, the machine operator will only have to select an existing program. The following programs exist as a factory setting:

Program 1: 1 main seam Program 2: 1 pre-seam with consecutive main seam Program 3: 2 pre-seams with consecutive main seam Program 4: 2 pre-seams, 1 seat seam with consecutive main

seam

Program 5: 1 seat seam, 2 pre-seams with consecutive main

seam

Program 6: 1 main seam without stop after photo cell lighted

The currently selected program is displayed in the left upper corner of the display (program 1 is selected in Pict. 5).

To select a different program, you have to move the cursor on the program number and press the ‘+’ / ‘-‘ keys repeatedly, until the desired program number is displayed.

6.3 Create own programs

ATTENTION

The changing and creation of programs should be done by experienced personell. The functionality of the machine can be influenced badly by wrong programming.

Hint

All functions and options are displayed as icons in a rectangle in the programs. Generally, a rectangle striked out twice means: function disabled. If the rectangle isn’t striked out, the function is enabled.

To create an own program, you will first have to adjust the setup data and then create the program. Setup data can only be displayed, if the machine code has been entered before:

7.1 Maintenance of the machine

This machine works nearly free of maintenance. To achieve the maximum ability of the machine for a long term, some regular maintenance duties are required.

DANGER

Before starting maintenance and repair duties, the following power down procedures are to be executed. Otherwise there could be danger to life.

Cut off mains power

 switch the mains / emergency stop switch to ‘0’ and assure

that it can’t be switched on

 check whether the machine is without current and that there

is no statical loading

Switch off pneumatic system

 close the main gauge  ventilate all pipes and gauges

Chapter 7: Cleaning and maintenance

7.1.3 Check the drive belt

Pict. 43 Check the drive belt

The drive belt (A) must have tension at all time but show a certain play (it must be possible to move it est. 1 cm up- and downwards).

If it is too loose, loosen the fixing screws of the motor (B) and push it in a waym that the drive belt gets more tension. Tighten the fixing screws again.

7.2 Required cleanings

To achieve the value and function of the machine, we recommend to keep it always clean and free of spare materials and waste.

Blow off threats and cloth rests daily or use an industrial vacuum cleaner.
