Definitions
- the invention relates to a punch from the contour punching of a precut Stack of benefits by means of a punching iron, with a feed plate for supporting the Benefit stack, a feeder for feeding the benefit stack to be punched to the punching iron, one the benefit pile against the punching iron pressing stamp and a device for conveying the finished punched Pile of sheets.
- the mentioned punch is used in particular for punching one out of a Variety of superimposed, printed labels formed benefit stack.
- This benefit stack of leafy good consists in particular of printed Paper.
- the individual labels are made of plastic, in particular plastic film. It is a very flexible one Material that also charges, leaving individual sheets of the benefit stack stick to each other.
- the precut benefit stacks are cuboidal.
- the punch serves to give benefit stacks their finished contour. This is how labels usually become printed on large printed sheets that range from several hundred to over a thousand be stacked on top of each other. Such printing sheet stack are pre-cut longitudinally and transversely, forming a plurality of benefit stacks be isolated.
- a closed contours punching punch To make the finished labels is a used a closed contours punching punch. After this the respective benefit stack by means of the feeder under the punch iron supplied, the benefit stack is by means of a punch against the punch iron pressed and punching performed. Then the finished punched out benefit stacks.
- the punching iron passes through a counter-pressure plate which is operatively connected with the benefit stack on its side facing away from the stamp can be brought.
- this counter-pressure plate can the finished punched stack of benefits pushed out of the punching iron and carried away by separate means become.
- a punch of the type mentioned is known from DE-U-91 15 347.
- the feeder consists of lateral, substantially vertical standing guide jaws, based on the feed direction of the feeder in the region of its rear end einschwenkbare transport jaws have, which laterally or end the precut benefit stack cross tabs are assigned.
- This transporting jaws comes solely the task to, one after the cut due to the wedge shape of the cutting knife parallelogram in pre-cut shifted Take advantage pile in the area of the lowest sheet layers and in Advance direction of the punch, being against the leading oblique Surface of the precut benefit stack an alignment stop is moved to align the stack of benefits in its cuboid shape. The aligned ' The load pile is advanced further to the punch by means of the transport jaws.
- the precut benefit stack can not properly pushed onto the stamp, as the lowest sheet position of the precut benefit stack gets stuck on the ridge. This is especially true when the individual sheet layers of flexible material, in particular consist of a plastic film.
- Object of the present invention is a punch of the aforementioned To provide a way to automatically load the punch, i. automatic Transfer the benefits stack into the scope of the stamp, with simple Structural effort and process is possible.
- the feed device has a loading trolley for the benefit stack, in the feeding direction of the benefit stack in the area of the punch and opposite the supply direction of the benefit stack is movable from this area, wherein the loading carriage relative to means for positioning the benefit stack assigned to the loading wagon.
- the actual displacement of the precut benefit stack to stamp by means of the loading carriage takes place.
- this loading wagon are the means for positioning the benefit stack movable relative to the loading cart. These means position the Use stack exactly, so that when reaching the desired position on the Stamp or precisely punched in the punch alignment of the punching iron can.
- the means for positioning the benefit stack relative to the loading wagon can be formed differently.
- a preferred embodiment provides that these means, with respect to the feed direction, a first, front feeder and a second, rear feeder, and the investors, for positioning of the benefit stack, are mutually adjustable. Is the distance the both investors greater than the dimension of the benefit stack between them, The benefit stack can be easily placed between investors, where this is done in particular by machine. Subsequently, the two investors moved towards each other, to a distance measure, according to the relevant Measure the benefit stack so that they position it between themselves.
- At the Procedure of the loading wagon becomes the benefit stack between the two investors held and moved along the feeder plate.
- This feed plate is tilted horizontally and / or transversely in the feed direction of the benefit stack arranged.
