Definitions

  • the invention relates to a device for punching a stack which is formed from leafy material, in particular a device for punching a stack of labels.
  • the stack is pushed into the punch knife by a relative movement of the punch and a hollow cylindrical punch knife.
  • the actual punching process is in As a rule, the punching knife is at a standstill, while the punch stamps the stack into the
  • a device of the aforementioned type is known from WO 96/12593.
  • the essence of the punching device described there is seen in the fact that an additional counter pressure stamp is provided, which serves the purpose of moving the punched stack out of the punching knife against the direction of insertion.
  • the object of the present invention is to provide a punching device in which an optimal positioning of the stack in the area of the punch is guaranteed, regardless of different stack sizes.
  • the invention proposes a device for punching a stack of leafy material, as defined in claim 1. It is proposed that the stack to be punched be positioned between a stop element and a movable insert element, the insert element being positioned against a stop and the stop element and the stop being adjustable.
  • the adjustment of the stop element serves the purpose of being able to position stacks with different, in particular rectangular, sheet surfaces symmetrically to the punch, in that the stop element is moved further away or closer perpendicular to the direction of travel of the punch.
  • the stop against which the insert element is positioned in its retracted end position is adjustable for the same purpose.
  • the stop element and the stop are preferably adjustable both with respect to the stack center and with respect to the stack format. The center adjustment is not necessary if the above-described adjustability of the punching knife relative to the punch is guaranteed.
  • the stop element and the movable insertion element preferably have a plurality of insertion fingers arranged parallel to one another and oriented in the insertion direction of the insertion element.
  • the insertion fingers are in particular plate-shaped and extend in the punching direction of the stack in grooves in the punch.
  • a hold-down should be able to be lowered onto the stack between the stop element and the insertion element.
  • an element is expediently movement-locked with the hold-down device connected, which detects a stack level exceeding the hold-down level of the hold-down device when the stack is inserted by means of the insertion element. If a stack is to be inserted into the area of the punch, which has larger dimensions in the direction of the hold-down device than the set hold-down level, the element detects the interference contour and at least interrupts the advance of the insert element, or even switches it
  • Insert element specifically the movement of the insert finger is not interpreted in the sense of an accident
  • an element for detecting the insert element is preferably additionally provided which, after the stack, the element for detecting the
  • Element for recognizing the interference contour arrives, is activated and the interference contour detection deactivated.
  • elements for the punching space cover are connected to the stop element and / or the insertion element and / or the hold-down device. If the stop element and the insertion element are adjusted synchronously, that is to say by means of an adjusting device, the cover elements assigned to them can also be moved synchronously.
  • the cover element which is firmly connected to the hold-down device, is also automatically adjusted when the hold-down device is adjusted, so that the area surrounding the stack is optimally covered by the punching space covers.
  • the punching knife is held in an adjustable manner in a frame which can be inserted perpendicularly to the relative travel direction of the punching punch and punching knife into a removal device and can be fixed in a centered position, the receiving device being mounted in a punching head plate so as to be relatively adjustable relative to the latter.
  • the frame that receives the punching knife is therefore not folded into the receiving device, which would require a relatively large amount of space between the punch and the punching head plate.
  • the device is very compact because the frame can be positioned in the narrowest space between the punch and the punching head plate, instead being inserted into the receiving device and perpendicular to the relative travel direction of Stamp and punch knife.
  • the frame can be fixed in a centered position, which presets the frame relative to the punching head plate. The frame and thus the punching knife can be further adjusted in that the pick-up device in the punching head plate is adjustable.
  • the frame can be guided in a particularly simple manner in the receiving device if it has two strips arranged in parallel, between which the frame can be inserted.
  • the frame itself is preferably adjustable in a plane parallel to the punching head plate, in particular adjustable in a superimposed manner in two main axis directions arranged substantially perpendicular to one another, and pivotable in this plane. So that the frame can follow the movement of the receiving device in a centered manner, it is provided, for example, with a groove which runs essentially in one main axis direction and into which a centering bolt which can be moved essentially in the other main axis direction and which is in particular mounted in the punching head plate is inserted.
  • the receiving device and / or the centering bolt are expediently adjustable by motor, the adjustment preferably being carried out synchronously. Electric motors are particularly suitable as actuators.
  • a clamping element is provided in particular. This fixing and / or the fixing of the frame in the centering pin is preferably carried out pneumatically.
  • the above-mentioned designs of the device ensure that the punch knife held in the frame and inserted into the device can be oriented in a defined manner with respect to the punch to be stacked, in particular in a plane perpendicular to the relative travel direction of the punch and punch knife, both from a translational and a rotary aspect.
  • a further training relates to the presetting of the punching knife in the frame.
  • the frame is equipped with tensioning elements mounted in it, which are adjustable and fixable relative to the frame, for fixing the punching knife, and an adjusting element mounted in the frame is provided for the aligned alignment of at least one alignment edge of the adjusting element with a knife edge section of the punching knife before fixing the set clamping elements. It is therefore not necessary to fix the punching knife in the frame by feeling, but it is done by means of a separate adjusting element. It is sufficient to use a particularly straight knife-edge section of the punching knife as a reference variable, which is to be brought into alignment with an alignment edge of the adjusting element.
  • This setting element is placed at a defined point on the frame, so that when the alignment edge of the alignment is aligned
  • Cutting knife is ensured relative to the frame.
  • the lateral alignment of the punch knife relative to the frame can be done in a simple manner by means of a central marking which is attached to the punch knife on the one hand and to the frame on the other and is also in alignment
  • the setting element can be designed in different ways.
  • the setting element is particularly simple in terms of construction when it is used as
  • This rod-shaped element is placed on the frame in a defined manner and the punching knife is aligned on the one alignment edge of the setting ruler.
  • Setting ruler is preferably based on the leading knife edge of the
  • Align knife edge This can be done easily if that
  • Adjustment film is formed, which is provided with an opening corresponding to the opening cross section of the punching knife in the region of the knife edge.
  • the adjusting film is arranged, for example in front of the punching knife, in relation to the leading knife edge of the punching knife, and is aligned with the frame.
  • the punching knife is then positioned so that its circumferential knife edge matches the opening contour of the film opening. This configuration considerably simplifies the presetting of the punching knife in the frame, so that only a small amount when the frame is inserted into the punching device
  • Position corrections of the punch knife or frame with respect to the punch and the stack to be punched are required, if this is the case at all.
  • a further training relates to the special fixation of the punch knife in the frame. It is essential here that tensioning elements mounted in the frame, adjustable and fixable relative to them, are provided for fixing the punching knife.
  • the frame has a frame part and a first clamping beam, which is displaceable and fixable in the frame part, the punching knife being held in the first clamping beam and the frame part, in a section of the frame part which is arranged parallel to the first clamping beam. Parallel to the first A second clamping beam is arranged, which is displaceable and fixable in the frame part.
  • clamping means are provided for clamping the first and second clamping bars in such a way that the first clamping bar can be clamped against the punching knife.
  • the task of the frame part and the first clamping beam is thus to accommodate the clamping elements for fixing the punching knife.
  • These tensioning elements which are designed in particular as clamping claws, fix the tensioning knife on sides of the punching knife facing away from one another, so that, under the action of the tensioning means of the second tensioning bar, the tensioning elements of the first tensioning bar presses the punching knife into the tensioning elements of the frame.
  • the punching knife By adjusting the clamping means, which contact the first clamping bar, the punching knife is fixed tightly between the clamping elements via the slight displacement of the first clamping bar. The tight connection between the first clamping beam and the frame is then established, with which the punching knife is held particularly firmly in the frame.
  • the frame is preferably designed to be closed and therefore rigid.
  • the connection between the first and / or second clamping beam and the frame part can be made in a positive or frictional manner.
  • the first and / or second clamping beam can be connected to the frame part in a form-fitting manner along wedge-shaped bearing sections, the wedge of the respective bearing section expanding away from the punching knife.
  • Another design relates to the special design of the support of the frame on the punching head plate and the direct introduction of force of the punching forces from the punching knife via the frame area assigned to the punching knife into the punching head plate.
  • the punch knife is adjustably held in the frame which is held in the receiving device which is connected to the punch head plate.
  • the mounting plate has the two parallel strips, between which the frame is held.
  • the frame has a frame part and at least an adjustable clamping bar in the frame part for fixing the punching knife. It is the
  • Frame part which is used to hold the punching knife, on the punching head plate. This one
