Definitions

  • the present invention relates to a retaining device for a stack of products according to the preamble of claim 1 and a method for supporting stacked Products for a transport device according to the preamble of claim 15.
  • US 5,447,302 is a device for removing paper products from one disclosed in a magazine or a pre-stack arranged stack.
  • the device comprises a rotatably arranged gripper drum, which is the lowest Subtracts sheet or the lowest signature of a stack of sheets or signatures.
  • Fig. 3 of the cited document a stack of sheets or signatures is shown, of which the Sheets or signatures are to be removed individually from the gripper drum. A part the sheet or signatures rests on a platform in such a way that a front one Section of the stack extends beyond the end of the platform. This front section is supported by a restraint.
  • Retainers hold the front portion of the stack in place and prevent the stack from sloping down over the platform edge. Moreover reduce the risk of having a second sheet or signature together with the sheet to be fed to the gripper device or the signature to be fed is sucked in.
  • the retention device described in the cited document prevents suction of double sheets but not reliable, so that sometimes more than one sheet in reaches the gripper area. There is a risk of malfunction, damage the arc and blocking the feeder.
  • the disclosed Retention device no sufficient adjustment options to the device z. B. to adapt to different types of paper or other products in the stack.
  • the object of the present invention is to provide a restraint device for a Product stack as well as a method of supporting a product stack to create a enable easy adjustment.
  • An additional or alternative object of the invention is a reliable and effective restraint device as well as a reliable one to provide an effective method of supporting a stack.
  • a retaining device according to the invention for a stack in a feed device comprises a base body and a retention knife attached to it, which during the operation of the feed device with respect to the base body is adjustable in angle.
  • the restraint device Due to the angular adjustability, the restraint device according to the invention can even can be adjusted during the operation of the associated feed device, so that a more precise and repeated adjustment of the retention function of the feed device is possible.
  • the "retention knife” does not have to be a Act knife.
  • the so-called “restraint knife” can be any object that the contacted the front section of the products in the stack, e.g. B. also an arcuate Extension, a bar or a ledge.
  • the restraint knife is preferably adjustable along an axis of the base body, where z. B. the height is adjustable via a pin.
  • the restraint preferably further comprises a lever arm on which the Retention knife is attached, the retention knife preferably from that Lever arm is removable.
  • a spring can be provided which turns the knife into a open position moves, the lever arm comprises a straight surface.
  • To the Adjusting the angle of the restraint knife can be against the straight surface acting set screw screwed into the body.
  • the Set screw is preferably outside a front guide of the feed device arranged.
  • the restraint preferably further comprises a support for supporting the Base body and for attaching the base body to the front guide of the Feeding device.
  • the base body is preferably slidable within the support adjustable so that the height of the restraint knife is adjustable.
  • One in the base body screwed, against the support rotating adjusting screw can be used to adjust Position of the base body with respect to the support.
  • a feed device comprises a front guide and at least a restraint, each of the restraints with the front Guide is connected and a base body and an attached to this Retention meter includes that in the operating state with respect to the base body is adjustable.
  • the restraints are preferably in the manner with the front guide connected that they are easily interchangeable, e.g. B. by means of a support plate and one Bolt.
  • the restraints are preferably along the front Guide adjustable in a direction perpendicular to the height.
  • the inventive method for supporting a stack of sheets in a Feeder provides that a sheet stack in the manner of a feeder that the front portion of the stack is positioned by a restraint is held and that an angular position of the restraint is adjusted, while the feeder is in an operating state.
  • the method preferably also provides that the restraint device is used during the Is adjustable.
  • the present invention advantageously enables height and Angle adjustment and other adjustments during the operation of the Feeding device without the need for tools.
  • the removable one Restraint knife and the removability of the entire restraint device enable a quick exchange.
  • Fig. 1 shows a feed device 1 with a front guide 5 and two Restraints 10 and 20.
  • the restraint 10 includes a support bar 11, a support plate 12 and bolts 13, which support plate 12 in the direction of Support bar 11 can push, so that the restraint 10 around the front Guide 5 is excited.
  • the support bar 11 may have a notch 14 have, which cooperates with the support bar 11.
  • the bolt 13 can over a Thread be screwed into a support arm 15 which is fixedly connected to the support strip 11.
  • a base body 22 with two at its upper end through an upper cross piece 26 and one lower crosspiece 28 and connected at its lower end by a pin 27
  • Side walls 24 are movably mounted with respect to the support arm 15 and the support plate 12.
  • the crosspiece 26 has a bore with an internal thread into which a height adjustment screw 30 is inserted with an external thread.
  • the screw 30 is rotatable on the support arm 15 arranged and causes rotation of the screw 30 due to the Screw action of the threads an upward or downward movement of the base body 22nd with respect to the support arm 15, as indicated by the arrow 70.
  • the screw 30 also has an unthreaded inner bore, into which an extension 42 an angle adjustment screw 40 can be inserted.
  • the extension 42 instructs its lower end has an external thread that mates with an internal thread of a hole in the lower crosspiece 28 can cooperate.
  • Contacted at its lower end Extension 42 has a straight surface 52 of a lever 50 that is rotatable about pin 27 is stored.
  • the lever 50 is clockwise around the pin 27 by means of a spring 53 spring loaded to counteract extension 42.
  • the extension 42 is due to the screw action with respect to the cross piece 28, the side wall 24 and the pin 27 moves up or down and thus the lever 50 around the Pin 27 rotated as arranged by arrow 80.
  • On the straight surface 52 A retaining knife 60 is attached to the side of the lever 50 facing away from the lever.
  • the restraint knife 60 may e.g. B. made of metal, preferably spring steel, have any shape consistent with the definition above, and either form an integral part of the lever 50 or be firmly connected thereto.
  • 3A a preferred embodiment of a restraint knife 60 is shown that is fixed is connected to the lever 50 which is biased by a spring 53 around the pin 27.
  • the restraint knife 60 has a curved support extension 62 at one end is held between a retaining pin 54 and a support surface 57. At the other end of the Extension 62, the retention knife 60 is held by a releasable pin 55 which fits exactly into a slot 56 of the lever 50. If the detachable pin 55 in the in Fig.
  • the restraint knife 60 can run through a recess 90 in the support strip 11, as shown in Fig. 1.
  • the retention knife 60 is preferably removable for easy replacement arranged as shown in Fig. 3B.
  • the releasable pin 55 can be in the slot 56 a Release position in which the restraint knife 60 is moved down along the Support surface 57 and can be moved away from the holding pin 54 and removed.
  • the present invention thus enables an exact height and Angle adjustment of the restraint knife 60 during the operation of the feed device.
  • Setting scales 95, 96 may be provided.
  • the restraint 20 can of course be substantially like that Restraint device 10 may be constructed. By loosening the bolts 13, the Retainers 10, 20 may be slidable along the front guide 5, such as is indicated by the arrow 92 in Fig. 1. To optimize their impact on the Printed products in the stack can position the retention members 10, 20 along the front section of the bow can be adjusted.
