Definitions

  • the invention relates to a punching and binding machine for sheet stacks with a punching mechanism which has an insertion gap delimited on one side by a punching die, preferably with adjustable depth and / or side stops for the sheets of the sheet stack to be provided with a number of binding holes near the edge, and which has a number of punching knives arranged at defined distances from one another along the insertion gap and movable through a first actuating member across the insertion spacing and the punching die, preferably individual punching knives as switching knives optionally being able to be decoupled from the other punching knives, and with a binding mechanism for binding the sheet stack by means of a through the binding holes elastic spine, which has two expansion bodies for spreading the spine, which is limited by a second actuator preferably by an adjustable stop relatively z are mutually movable.
  • Combined punching and binding machines of this type have different adjustment mechanisms for the depth stop and the side stop of the punching mechanism and for the limitation of the spreading bodies of the binding mechanism, which are each to be set separately from one another by hand.
  • the punching mechanism has an actuating lever, the rotational movement of which is converted into a translational movement of the punching knife.
  • individual punching knives arranged on a knife carrier can optionally be uncoupled by hand.
  • there is a binding mechanism with two expansion bodies, which have a large number of hook elements for hanging the back of the binding and which are operated with the aid of an Actuating lever trained actuator can be moved apart by spreading a suspended ridge.
  • the width of the spread can be limited using a manually adjustable stop.
  • the object of the invention is to improve the known punching and binding machines of the type specified at the outset in such a way that the setting processes are simplified and the risk of incorrect operation is largely avoided.
  • the solution according to the invention is based on the knowledge that the various settings to be made on the punching and binding machine partially correlate with one another, taking into account the sheet formats and stack dimensions present in each case.
  • this knowledge is used, several adjustment devices are coupled to one another in such a way that only a few, clear settings are necessary for each change in size of the punched and bonded goods.

With this measure it is possible to stack a sheet with to provide a given sheet format with a symmetrical perforation pattern with respect to the lower and upper edge and at the same time to ensure that no forbidden edge openings occur in the given format setting.
  • the setting member has a plurality of positioning positions, preferably defined via a scale and / or locking positions, with predefined assignments of the side stop and the coupling state of the switching knives.
  • the adjusting mechanism for the side stop expediently has a plunger which has a stop element at its end and can be displaced via the adjusting element in the longitudinal direction of the insertion gap.
  • the adjusting element which is expediently designed as a rotary knob, is advantageously coupled to a cam wheel which has an adjusting curve for receiving a slide block which is fixed to the tappet.
  • the adjusting element has an adjusting element for the fine adjustment of the side stop in every setting position of the adjusting element.
  • the fine adjustment can be achieved technically by the cam wheel being connected to the rotary knob in a rotationally fixed and axially displaceable manner, while the adjusting member can be rotated to a limited extent with respect to the rotary button and engages with at least one sliding block in a preferably helical fine adjustment curve of the cam wheel.
  • the cam wheel has at least two, preferably three of the same type, fine-adjustment curves arranged at an angular distance from one another for receiving a corresponding number of sliding blocks arranged at an angular distance from one another on the adjusting member.
  • the clutch mechanism for the switching knives has a camshaft coupled in a rotationally fixed manner to the adjusting element designed as a rotary knob, each having a cam curve assigned to one of the switching knives, and each having a locking element that is radially adjustable via the associated cam curve.
  • the punching knives including the switching knives, are expediently arranged on a knife shaft which is concentric with the camshaft and have a stamped part which is curved at a radial distance from the surface of the knife shaft, so that they can be actuated by rotating the knife shaft, triggering a punching process.
  • the switching knives and the knife shaft are advantageously axially immovable relative to one another and rotatable relative to one another about the common axis of rotation.
  • the locking element designed as a locking pin engages through a radial bore in the knife shaft, in the locking position under the action of the cam cam in question it engages in a radial bore of the switching knife which is open to the radially inner knife shaft and in the switch-off position from the radial hole of the switching knife in Is pushed out in the direction of the knife shaft and thereby releases the relative rotation between the switching knife and the knife shaft.
  • the switched-off switching knife is taken along under the action of static friction up to the stop against the sheet stack.
  • the friction is not sufficient to trigger a punching process due to the lack of a positive coupling.
