Definitions

  • the invention relates to an apparatus and a method for opening an end region of a tubular bag body, which end region extends between an open hose end and a bottom center line, with a transport device on which the bag body with adjacent hose walls with a transport speed in a transport direction is transportable, wherein Bottom center line is aligned in the transport direction, and with transversely to the transport direction reciprocally driven suction devices that are movable towards each other until they rest 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 pull the tube walls away from each other.
  • 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.
  • the bottom opening device with the aid of which the two layers are separated from one another at the end region of the tubular bag body, is designed as a pneumatic bottom opening device in which suction devices lying opposite each other with respect to the material layers to be separated are provided, which engage the tube walls of the bag body and the sequence are moved apart, whereby the tube walls are separated from each other, so that the spreading tool can intervene therebetween.
  • Known floor opening devices such as the AT 408 427 B can be seen, are relatively large-sized constructions in which a linear opening movement is realized by means of cylinder / piston units. It is obvious that such a solution is relatively bulky and cost and maintenance intensive.
  • the present invention is therefore an object of the invention to provide a bottom opening device for Sackkon Anlagenionsanlagen, with a continuous operation of the system is reliably ensured at a high production rate, the bottom opening device should be simple, inexpensive and robust and wear resistant as possible. Furthermore, the bottom opening device should also allow the safe opening of different widths of floors and a correct transfer to the following processing station and of course be suitable for continuous operation.

  • the point of application of the suction devices on the tube walls can be controlled with respect to the mid-center line and even adjusted during operation, whereby the opening device can be adapted to end regions of different lengths which are formed into bag bases of different widths.
  • the opening device according to the invention it is possible with the opening device according to the invention to adjust the points of application of the suction devices on the tube walls to be separated so that they are as close as possible to the outer end of the bag body, whereby the precision of the opening operation is increased.
  • the device according to the invention is particularly suitable for processing bag bodies made of stretched plastic tapes and / or plastic film, wherein the plastic material is preferably selected from polyethylene, polypropylene and / or PET. Also composites of the materials mentioned can be processed, and the bag body can be provided with a plastic coating.
  • the web of stretched plastic tape may be provided with a plastic coating to achieve the tightness of the web, to improve printability, and to adjust other desirable properties. Sacks of stretched plastic tape have superior strength over paper or plastic film bags, but tend to slip in the manufacturing process and are also harder to fold than, for example, paper. Therefore, it is of particular advantage that these bag bodies can be handled by the present invention.
  • bottoms can be formed at both opposite end regions of the tubular sack body, or a bottom can be formed only at one end region.
  • the opening device according to the invention can be adapted particularly easy for the mounting of different wide bottoms and different width bag bodies become.
  • a shallow angle is chosen against the mid-ground line, and for steeper soils, a steeper angle can be set.
  • the precision of the opening operation is increased when the angle of the oblique direction to the center of the ground line is less than 45 °, preferably less than 30 °.

  • the pivot arms are displaceable together in the oblique direction and can therefore in continuous operation of a bag making machine in a simple manner during the opening process with the continuously conveyed bag bodies be moved.
  • the pivot arms of the respective parallelogram unit can be driven in any desired manner. It is conceivable to actuate the pivot arms by means of servo motors or motor / gear groups, hydraulic or pneumatic cylinder-piston units or via cables. According to a preferred embodiment of the present invention, however, it is provided that in each case a pivoting arm is driven via an angle lever and connected to the angle levers rods which are hinged to a control slide. Due to the parallelogram arrangement of the pivot lever, it is sufficient to actuate only a single pivot arm of a parallelogram unit, since the other elements of the parallelogram are forcibly guided.

  • peripheral drives in particular toothed belt drives, are preferred as drives for the carrier slide and the control slide.
  • Timing belt drives are known to be reliable even with long running times and can be quickly replaced if necessary without the need for specially trained personnel.
  • the displacement of the carrier carriage and the control slide could also be done by means of cylinder / piston drives, spindle drives or servomotors.
  • the present invention is preferably further developed such that opposing suction devices are arranged offset from one another, whereby they attack each other offset to the tube walls to be separated. With such a positioning of the suction devices to each other succeeds a reliable separation of the tube walls.
  • the guide rail is adjustable by means of adjustable storage with an adjustable angle in the oblique direction to the bottom center line.
  • the adjustable bearing comprises elongated holes with recesses defined by recesses, a rapid change between different settings of the angle to the ground center line is possible. Switching between positions can be done with simple tools and, if necessary, by a single person.
  • a particularly advantageous embodiment can be achieved if the mounting of the guide rail is adjustable by means of a motor drive.
