Definitions

  • the invention relates to a diameter (cf. US 4,872,382 A) which can be changed Knife roller with one extending parallel to the roller axis and knives standing radially on a diameter plane, that on a radially outward and inward adjustable knife carrier is attached.
  • Knife rollers for making cross cuts or cross cuts are in different embodiments known. Under “knives” are both smooth cuts as well as knives that perform perforated lines. According to the different formats of workpieces and preferably bag workpieces must have sheets of paper or plastic at different intervals with cross sections and in particular with cross perforation cuts. It is hence a need to cut knife rollers quickly and easily to different To be able to set formats.
  • the object of the invention is therefore a knife roller of the beginning to create specified type that is quick and easy to different formats, i.e. to different distances to be carried out on a continuously conveyed track Cuts, adjust.
  • this object is achieved with a knife roller of the generic type Art solved in that the knife holder with the the two links connecting two scissor lever joints or each with one of the arms protruding from these joints one of the Handlebar of the two scissor levers is articulated and that each an inner joint of a handlebar one of the two scissor levers firmly on a cutter block shaft and the other inner joint of the other handlebars adjustable in the axial direction or is arranged in the knife roller shaft.
  • the radial distance of the knife holder and thus the format of a web to be separated or separated by cross perforation lines Sections can be in through the knife roller according to the invention simply by adjusting one of the inner joints the handlebars of the scissors levers adjust in the axial direction.
  • the knife roller shaft is expediently a hollow shaft, in which a slide arrangement is guided axially displaceably which arranged the adjustable inner joints of the other handlebars are, the slide assembly with an actuator is provided.
  • the actuator can be connected to the slide assembly Spindle nut and an adjustment screw that can be screwed into this consist.
  • the spindle is immovable in the axial direction relative to the hollow shaft held and after loosening a holding or locking device be rotatable relative to this.
  • the Spindle on a radially extending carrier of the hollow shaft in this is freely rotatably mounted on an end section the spindle is a non-rotating and axially displaceable bush is stored, which is on an annular shoulder on a Counter ring shoulder of the hollow shaft or one connected to it Braking housing can support and that of a section enclosing compression spring is applied, the one hand on the socket and on the other hand on a collar or on supports a nut screwed onto the spindle, and that a device for moving the socket out of its braking position is provided for non-rotatable holding of the socket.
  • Embodiment of the invention enables simple adjustment the knife holder in that when pressed and rotatable held sleeve, the hollow shaft is rotated so that on the Spindle nut moved the slide assembly in the hollow shaft and the knife carrier is adjusted in the desired manner.
  • the device for moving away and holding the socket can a pressure-piston-cylinder unit arranged fixed to the frame exist, the piston rod of a non-rotatable coupling with claws, which engage in receptacles of the socket, these are non-rotatable hold and push out of their braking position.
  • the braking effect to increase, is expediently between the ring shoulder and the counter ring shoulder is a brake ring made of friction-increasing Material inserted.
  • the Hollow shaft is driven by a controllable stepper motor.
  • This stepper motor can be controlled by a computer in this way be that the hollow shaft for adjusting the knife carrier is rotated to a position in which the claws of the coupling piece aligned with the receptacles of the socket. Are the claws in the receptacles of the socket retracted and the claws have the Pushing the socket out of its braking position can via the Computer the hollow shaft is rotated through a certain angle, to effect the desired radial adjustment of the male connector.
  • Knife holder can be held adjustable. Are preferably mirror images to a diameter plane of the cutter block shaft two Knife holder holding scissor levers arranged, the inner Handlebars are mounted on common pins. Offset by 90 ° These two knife carriers can hold two more knife carriers be arranged adjustable in the same way.
  • the knife carriers are expediently made up of two in pairs arranged scissor levers worn, for stability the knife carrier increased.
  • Knife is attached to a male header by pairs Clamping levers mounted on the side of the knife carrier can be released with this connected is. This arrangement enables quick replacement the knife when these have become blunt or a another cut or perforation cut is desired.
  • the clamping levers expediently consist of pivotable on the Knife carrier mounted angle levers, each of which is supported by a Compression spring is applied in the opening direction and one after has inside pointing arm, on which the clamping lever in his Device holding the locking position attacks.
  • This Device can be axially displaceable in the knife carrier guided locking rod or consist of a slide, which is provided with cams or rollers for locking the clamping lever on ramp surfaces of their inner arms come up and can be moved to unlock them.
  • the Slider can be loaded by a spring in the unlocking direction and in its locking position detachable from one in its Be held above dead center position pivotable lever.
  • An adhesive application roller can also be used in the same way as the knife roller be designed, the format is a continuous Web with adhesive applications or transverse adhesive applications provides. According to a further embodiment of the The invention is therefore provided for the knife holder to be a holder for an adhesive application bar.
