Definitions

  • the invention relates to a device for opening an end region of a tubular bag body, according to the preamble of claim 1.
  • Chest bags also called cross-bottom bags, are bags of cuboidal shape which are made in bag making machines by providing tubular bag bodies whose end portions are opened and folded into cross bottoms. The bag bodies are guided lying flat when folding through the clothing plant, so that the tube walls of the tubular bag body abut each other, especially at the end portions of the tubular bag body.
  • the two tube walls are separated from each other at the end regions of the tubular bag body and folded over 180 ° with respect to each other, usually one of the two tube walls is folded over with the help of a spreading tool as a side flap on itself, creating an open bottom, in which the another hose wall forms a second side flap.
  • valve sheets can be inserted for the production of box valve bags, which are formed by further folding operations to a valve through which the bags can be filled by means of a filler neck.
  • the final bottom configuration is made by overlapping the bottom side flaps.
  • the overlapping bottom side flaps are glued or welded depending on the material.
  • bottom cover sheets can be placed on the overlapping bottom side flaps and adhesively bonded or welded thereto.

  • On both sides of the bottom center line are arranged transversely to the transport direction reciprocally driven suction devices which are movable until it rests against the tube walls of the intermediate end portion of the bag body and thereafter, while exerting a suction force on the respective tube wall away from each other, whereby they move the Pull hose walls away from each other, wherein the suction devices are additionally movable in and against the transport direction.
  • the suction devices are mounted on first joints, wherein at each first joint, two pivot arms are pivotally hinged relative to each other, wherein each pivot arm is pivotally connected by means of a second joint with a Stellschwenkarm, each Stellstell arm is driven to move.
  • the suction devices can be driven at a higher speed, whereby compared to the prior art, the transport speed of the transport device further increased and thus the production rate of bags can be further increased.

Due to the variability of the angle of the working plane, the device according to the invention can be particularly easily adapted for the mounting of different widths of floors and different width bag bodies. For narrow floors, an angle of 0 ° or a flat angle to the bag conveying plane is chosen, and for steeper floors a steeper angle can be set. With such a construction, it is further ensured that the opening device correctly transfers the opened end region to a subsequent processing station, in particular to a spreading device, without having to accept an unguided or undefined state between the opening of the end region and its further processing.
