Definitions

  • the invention relates to a system for erecting Cardboard blanks - with machine frame, at least one Magazine slot for a stack of cardboard blanks, a take-off device with which the cardboard blanks in succession are individually peelable from the stack, and one Transport device, which the removed from the stack Cardboard blanks and a device for erecting feeds the carton blanks with the trigger device as a vacuum device to which vacuum can be applied is formed, wherein the transport device is an endless conveyor with parallel and spaced apart Has tension elements, and wherein the magazine shaft above and the trigger below Transport device are arranged.
  • cardboard blanks are all common types of cards, such as full cards, e-wave, B-wave, and the like can be used.
  • a system with the features described is from EP-A-0 164 585 known.
  • To ensure the transport of the Cardboard blanks are driver fingers on the endless conveyor arranged.
  • the correct alignment of the cardboard blanks for the subsequent erection process is by parallel aligned guide rails guaranteed, which are attached to the machine frame.
  • the magazine shaft is oriented obliquely downwards, and the suction device is by rotating against the bottom Carton blank of the stack movable.
  • the trigger device from a gripper that cuts the cardboard blanks on the top or Underside of the stack, a swivel and / or Executes transverse movement and the recorded Cardboard blanks on a side or bottom Transport device, which has drivers, stores.
  • the kinematics are relatively complex and their constructive Implementation mechanically complex. It is not possible, different formats of cardboard blanks in Manipulate change. Finally, the accessibility the magazine shafts in need of improvement.
  • the invention has for its object a flexible system of the type described at the outset characterized by a particularly simple kinematics, thereby high performance enables and without further ado System changes can be adjusted.
  • Magazine slot is aligned vertically and at its lower, open-ended end edge-side contact surfaces for the stack has that the tension elements in The upper run of the endless conveyor is guided over suction boxes and the carton blanks moved by the transport device under the effect of one generated in the suction boxes Negative pressure on the tension elements, and that the suction device in the longitudinal axis of the magazine shaft movable up and down and against the on Supporting areas of the lower carton blank of the stack is movable and this under suction between the Subtracts down and continuously on the moving endless conveyor.
  • the invention uses the realization that the cardboard blanks are elastically deformable are due to this elasticity and accordingly sufficient traction by a smaller, from limited opening at the bottom of the shaft can be deducted.
  • the suction device only leads a short stroke and lifts it by suction peeled cardboard blank on the tension elements from the endless conveyor, with the smallest possible distance below the Magazine shaft is arranged. Because the suction device only small vertical strokes are short Cycle times attainable. It also results in a more compact one Construction of the plant. Finally, it is advantageous that the Magazine shaft is freely accessible on the top and sides.
  • the suction device preferably has a linear one Actuating device, for example cylinder / piston arrangement, connected suction head with several suction cups.
  • a control device which controls the Suction cups during the upward movement of the piston with vacuum acted upon and the suction cups during the downward movement when depositing the cardboard blank on the endless conveyor ventilated.
  • the contact surfaces expediently consist of support strips or support blocks that are adjustable on the machine frame are attached.
  • the adjustment of the support slats or support blocks only occurs when the format is changed.
  • the magazine shaft preferably has an attachment that detachable on the machine frame by means of a plug connection is held. When changing the format, the attachment can easily be replaced.
  • the tension elements Possibilities. It is essential that the cardboard blanks are supported and the negative pressure generated in the suction boxes lies against the cardboard blanks and this thereby on the Tension elements fixed. Perforated tapes are suitable, for example and the same. According to a preferred embodiment of the Invention, the tension elements each consist of a pair cords arranged parallel to each other, the lateral one Distance between the cords essentially the width of the Suction boxes corresponds.
  • the invention teaches that a A plurality of magazine slots with assigned, identical trained suction devices in the direction of transport Endless conveyor are arranged one behind the other. Cardboard blanks can alternate from the one behind the other arranged magazine shafts can be removed. from that there are numerous practical advantages. That's the way it is possible to cut the cardboard with an even shorter time sequence on the tape by the Work cycles of the suction devices corresponding to one another be coordinated. There is also the possibility of Magazine slots with different cardboard cuts load, be it that the cardboard blanks with different prints are provided and / or have different formats. In any one the cardboard blanks from the given order Magazine slots are requested. This enables one very flexible operation of the system. In the further course the cardboard blanks into the erector station transported. Since the tension elements (transport belts) with a constant speed is a safe contact with the centering device of the Format tool guaranteed. Accordingly, the Precision of the erector ensured.
  • the device for erecting the cardboard blanks has usually a linear punch drive, preferably via servo-driven linear axes, with up and down movable erection stamp and one with the Raising stamp interacting format tool.
  • the scope of the invention is to select the punch drive to be arranged above or below the transport device, whereby flexible adjustments to the system according to the invention System changes are possible.
  • To manipulate The invention teaches container blanks that the linear Stamp drive above the transport device and that Format tool, which with the erection stamp cooperates, arranged below the transport device is. If the erection stamp is used to hold primary packaged products, e.g. filled plastic bags and the like can be set up in one operation of the container and the introduction of packaging goods in one Operation.
  • the invention teaches that the linear Stamp drive below the transport device and that Format tool arranged above the transport device is. There is a turning when straightening the lid blanks not necessary anymore. Furthermore, the lid on a Point that corresponds to the height of the cover, so that the lid on a container without an intermediate stroke can be put on.
  • the erection stamp as well as the Format tools preferably have adjustable surfaces and can automatically start according to a control program different formats can be adapted.
  • the invention teaches that a Gluing device along the transport route of the Endless conveyor between the magazine shaft and the Device for erecting the cardboard blanks provided is. Since the endless conveyor with preferably constant and compared to conventional low-speed systems is very uniform Gluing at the designated places of the Packaging cuts possible.
  • the system according to the invention is characterized by a compact structure. It allows high performance, so manipulating a large number of blanks per Unit of time at a relatively low transport speed of the endless conveyor. The high performance is achievable by a small stroke of the trigger device, if necessary in connection with a plurality of more coordinated with respect to the work cycle Magazine compartments.
  • the system according to the invention allows Manipulation of blanks with large blanking tolerances, whereby curved curved blanks are also processed can be. Large-format cuts can also be made handle.
  • the system according to the invention is flexibly adaptable with system changes, allows a quick format change and also enables the simultaneous processing of several Formats that can be made from different devices without retrofitting the device Magazine slots are deducted. There are special advantages compared to the state of the art Manipulation of lid blanks.
