The invention relates to a device for removing sheets, labels and others Blanks from a stack, which together and individually to the treatment station of a paper processing machine, for example, the application roller must be fed to a gluing machine. Here the foremost blank is removed with a back and forth to a removal roller. of this retractable stacking container.

When working with gluing machines, in which sheets, labels or other blanks with a Adhesive application provided and then applied by hand to the object to be glued, the individual insertion of the blanks to be glued into the machine has proven to be cumbersome and time-consuming proven. The use of separating and feeding devices in cause the feeding of a blank with a uniform work cycle, proved to be inexpedient because the manual operation that follows the gluing process is different in terms of working hours. About that In addition, the construction resources for such a device in connection with a relatively simple gluing machine too big.

The object of the invention is now to create a device for removing individual sheets, labels and other blanks from one Stack, which is characterized by particular simplicity and which allows the operator to use the To determine the feeding sequence in coordination with the subsequent manual work process. Of the For this purpose, the stacking container is slidably arranged on the machine frame. To move forward of the stacking container is a manual operation, the return movement of the stacking container after removal the blank automatically triggering lever linkage provided. About the feeding of the blank To secure, a counter roller cooperating with the removal roller is arranged. The order is made so that a spring is arranged between the stacking container and the machine frame, so that the stacking container moves non-positively against the force of this spring in the direction of the feed roller and the blank to be removed is placed against the feed roller, after which it is canceled the frictional connection of the stacking container automatically into its starting position under the action of the spring force moved back. The forward and backward movement is regulated by a ratchet mechanism.

The lever linkage causing the forward movement of the stacking container forms part of this ratchet mechanism, which is provided with a nose and is arranged on the lever linkage in such a way that, at the end of its pivoting range, it moves against a blank singling and feeding device on the machine frame
for gluing machines

provided stop and thus brings about the release of the spring-loaded stacking container.

In order to ensure that the leading edge of the blank to be removed is safely inserted into the through the removal roller'c and to ensure the gap formed by the counter roller is the one that supports the stack of blanks Plate of the sliding stacking container in the removal area with one over the front edge of the stack protruding, so shaped extension provided that the lower edge of the blank to be removed deflected from the intended direction of movement and inevitably into the inlet area of the Removal and the counter roller is brought.

In the following the invention with reference to the embodiment illustrated with the drawings described.

1 to 3 show a side view of the device in various working positions;

Fig. 4 shows a top view of the device.

The gluing machine consists in a known manner from the storage container 1 for the adhesive from which Scoop 2, the applicator roller 3, the feed rollers 4, 5 and against the peripheral surface of the Application roller 3 abutting strippers 6. The gluing machine is the one shown with the figures Removal and feed device for the blanks to be glued upstream. This device consists of the holder 7 attached to the machine frame with the guide track 8 for the sliding Stacking container. The stacking container is through

Claims (5)

the frame 9 is formed, to which the guide rollers 10 are attached and which carries the stack of blanks 12 with its inclined stacking plate 11. On an extension 13 of the frame 9, retaining strips 14 are attached, which rest against the end face of the blank stack 12 and support it. A weighting plate 15 rests against the rear side of the stack of blanks 12, which slides with guide pins 16 into a slot 17 in the stacking plate 11 and holds the stack of blanks 12. The holder 7 attached to the machine frame carries an angle lever 18 which can be pivoted about a fixed pivot point and which is placed against the stop pin 20 under the influence of the tension spring 19. The leg 21 of the angle lever 18 carries a pawl 23 which is under the influence of the tension spring 22 and which grips an extension 24 of the frame 9 of the stacking container. The pawl 23 is provided with a nose 25 which is acted upon by the fixed, adjustable stop 26. An abutment 27 for a compression spring 28 is also provided on the frame 9, the other end of which is supported against a fixed point on the machine frame. The mode of operation of the device is as follows: Starting from the position shown in FIG placed against the feed roller 4 and is withdrawn from the stack plane by rotating it downwards .. The protruding over the front stack plane extension 29 of the stacking plate 11 causes, as illustrated with FIG 5 nip formed. At the same time, at the end of the forward movement of the stacking container, the nose 25 of the pawl 23 touches the stationary stop 26, whereby, as shown in FIG Force of the compression spring 28 moves back into its starting position. As the feed rollers 4, 5 continue to rotate, the blank reaches the area of the applicator roller 3 and is peeled off from its peripheral surface by the scraper 6. P A T Ii N T REQUESTS: 1. Device for removing blanks from a stack and feeding them, in particular to gluing machines, with one that can be moved to and from a removal roller Stackable container, characterized in that for the forward movement of the stackable container one of Manually operated, the return movement of the stacking container automatically after removing the blank triggering lever linkage provided and for feeding the blank one with the removal roller cooperating counter roller is arranged. 2. Apparatus according to claim 1, characterized in that the back and forth movement of the stacking container a latch mechanism (23 to 25) is provided. 3. Apparatus according to claim 1, characterized in that between the stacking container and Machine frame a spring (28) which is tensioned during the forward movement of the stack is arranged. ' 4. Apparatus according to claim. 1, characterized in that the pawl (23) has a nose (25) provided and so on the angle lever causing the forward movement of the stacking container (18) is arranged that it is at the end of its pivoting range against one on the machine frame provided stop (26) and thus the release of the spring pressure Caused stacking container. 5. Apparatus according to claim. 1, characterized in that the stack of blanks (12) carrying Plate (11) of the displaceable stacking container (9) in the removal area with an over the front stack edge protruding extension (29) is provided, which the lower edge of the to be removed Diverting the blank from the initial direction of movement and into the inlet area of the feed roller pair (4, 5) brings.
