409839/0760

Then one can be actuated by pulling back the slide 36 Limit switch (LS-1) actuated.

When the block box 48 strikes the rear stop plate 16a (Fig. 6a) on the first section of the discs 1 and 2, a limiting air valve (LV-2) provided thereon is actuated so that compressed air is fed into the air cylinder 19a and the block box 48 is pressed against the side stop plate 17a (Fig. 6b). The side stop plate 17a has a restriction air valve (LV-3) so that when the block box 48 is pressed against the plate 17a is operated, the valve (LV-3) is operated to supply compressed air into the air cylinder of the upper press 12a and thereby its Lower the press head 14a (Fig. 6c). The press head 14a has a restriction air valve (LV-4) in the recess 20 on it Underside which is arranged so that it is actuated when it comes into contact with the battery hood 47. If that Valve (LV-4) is actuated, a vacuum is applied to the battery hood 47 through the suction part 21 in the recess 20. After a short period of time has passed via a compressed air timer (T-2), the upper press head 14a becomes the Press 12a is moved upward, and thus the battery hood 47 is raised together with the upward movement of the press head 14a (Fig. 6d). A number of guide rods run perpendicularly through the upper disk 1 from the edges of the press head 14a 49, on which a limiting air valve (LV-5) is provided, which in the raised position of the upper press head 14a is operated to stop it. A limit switch (LS-2) is similarly provided so that it is switched on when the upper press head 14a is moved up.

In the second step on the second section of the discs, compressed air is fed into the air cylinder of the upper press 12b, if the restriction air valve (LV-4), the first step

is operated so that the battery hood 47 together with the downward movement of the upper press head 14b (Fig. 7a) drops and comes into contact with the heating plate 25. The press head 14b has a limiting air valve on its underside (LV-6) protruding downward from the outside of the recess 20. The valve (LV-6) will then operated when the underside of the battery hood 47 comes into contact with the heating plate 25. This becomes a compressed air timer (T-3) excited. After a certain time has elapsed via the timer (T-3), compressed air is fed into the cylinder of the lower press 13b to raise the lower press head 15b and the block box 48 with the heating plate 25 in To bring contact (Fig. 7b), and a compressed air timer (T-4) is energized. Then the battery hood 47 and the Block boxes 48 both made of thermoplastic resin are partially melted by the heating plate 25. After this When a certain time has elapsed via the timer (T-4), the upper and lower press heads 14b and 15b become respectively raised and lowered and separated from the heating plate 25 (Fig. 7c), whereby the limiting air valves (LV-5) and (LV-7) operated on the guide rods 49 and 50 of the upper and lower press heads 14b and 15b are provided in the upper and lower positions of the heads, respectively. the Limitation air valves (LV-5) and (LV-7) switch on the limit switches (LS-3) and (LS-4).

In the third step on the third section of the discs, compressed air is fed into the air cylinder of the upper press 12c, after the timer (T-4) mentioned in the second step is operated so that the upper press head 14c moves downward will. With this, the battery hood 47 is pressed against the block box 48 for a time determined by a timer (T-5) pressed, which has the consequence that the melted areas of the battery hood and the block box in one piece with each other be connected (Fig. 8). After using the time

member (T-5) a time has passed, the vacuum applied to the battery hood 47 is released.

In the fourth step on the fourth section of the discs, the upper press head I4d is moved upwards (FIG. 9a) and the side press 19d is released after a certain time has elapsed via a timer (T-6) (Fig. 9b). Through the Upward movement of the press head I4d will be the limiting air valve (LV-5) and a limit switch (LS-5) actuated. The limit switch (LS-5) energizes a solenoid air valve (SV-2), so that compressed air is passed into the air cylinder 40 of the dispenser 30. Then the arm 28 moves inward towards the fixed axis 4, and the articulated hooks 49 capture the rear surface of the block box. In this situation comes the outer end of the arm extending through the elongated opening 32d in contact with a restriction air valve (LV-8) and operates this, which is provided at the inner end of the opening 32d, so that pressurized air is fed into the cylinder 40 is to move the arm 38 outward, whereby the Block box with the battery cover is loaded onto the delivery rollers 37. In the retracted position of the arm 38a a limit switch (LS-6) switched on.

As can be readily understood from the flowchart and description shown in Fig. 5, all of the above are implemented Process steps simultaneously on four different ones Sub-sections of the slices carried out. As shown in the flow chart of Fig. 5, the rotary actuator becomes 11 driven to rotate the disks up to 90 ° clockwise as shown by an arrow is when all limit switches (LS-1), (LS-2), (LS-3), (LS-4) and (LS-6) are switched on. By turning the gear 10 a limit switch (LS-7) is switched on, which actuates the stop 44 for discs 1 and 2 and the clutch in the actuator 11 solves. If the stop block 42 against the block
