Definitions

  • Pressing device for bags provided with glued bottoms
  • the invention relates to a pressing device for bags provided with glued bottoms according to claim 1.
  • the glued bottoms of sacks especially paper sacks, must be pressed together immediately after gluing in order to prevent the bottom folds from erecting while loosening the glue.
  • a durable bond is achieved by pressing the floor areas.
  • the sacks are first placed on top of one another in a scale-forming station.
  • the bottoms of the sacks are then pressed in the pressing device.
  • the bags are stacked in a bag stacking station and transported away.
  • the bag bottoms are conveyed in conveyor belts comprising press belts, the press belts compressing the bottoms of the bags.
  • the latter has at least two press cylinders which are wrapped around by the press belts, so that the press belts cover an S-shaped or a multiple S-shaped path.
  • Known pressing devices are designed for operation on one long side of the machine frame. Often these crimping devices are part of a larger system like a floor layer. In the daily operation of such a However, the operator must also partially carry out work on the other long side of the pressing device or the system. However, operating the pressing device on both sides is not possible since the operating personnel cannot get to the other long side of the pressing device without leaving the operating area of the pressing device for a certain time.
  • the object of the present invention is therefore to propose a pressing device which enables the pressing device or the system comprising the pressing device to be operated on both sides.
  • the drive means, guide means and / or press cylinder pairs guiding and / or driving the press belts are arranged in the machine frame in such a way that the press belts are guided over at least one bridge-like location on the machine frame.
  • the machine frame has an accessible space in the area under the bridge-like area. This free space can be used by the operating personnel to get from one long side of the machine frame to the other long side.
  • the machine frame can have one or more supports in which or in which the guide means guiding the press belts are mounted.
  • Guide means can be rollers or rollers on which the press belts are guided. The rollers or rollers can also be driven so that they represent drive means for the press belts.
  • the press belts can also be guided in the region of the bridge-like location without any support from drive or guide means.
  • the machine frame can be interrupted at this point.
  • the bridge-like location of the machine frame is located directly behind the scale formation station.
  • the press belts following the scale formation station advantageously initially rise in order to then reach a height which allows sufficient free space in the adjoining area.
  • a carrier can be provided in which the drive and / or guide means guiding the press belts are mounted.
  • the carrier can be attached at one end to the machine frame, so that it represents a projecting component of the machine frame. In this case, the support does not need to be additionally supported at its second end.
  • the free space extends to the level on which the pressing device is constructed.
  • this is the floor of a factory hall, which carries both the scale formation station, the pressing device and the bag stacking station.
  • the lower end of the free space is therefore in particular not limited by components of the machine frame.
  • a particularly preferred embodiment of the invention has a free space which has a dimension of at least 500 mm in the direction of transport of the bags. This dimension represents a passage width of the free space in which the operating personnel can change the operating side very easily.
  • This separating device can be formed by sheets. In order to allow a view of the machine parts and the bags to be pressed, this separating device can also consist of a grid or plexiglass panes.
  • the free space is arranged between the scale formation station and a device for deflecting the scale flow consisting of the shingled sacks, in which the scale flow is deflected by at least 120 °.
  • a device for deflecting the scale flow usually consists of a pair of press cylinders.
  • the bags describe an approximately S-shaped path along the surfaces of these press cylinders.
  • the bags are at an angle of at least 120 ° over each press cylinder.
  • Such a device for deflecting the scale flow can, however, also be implemented with a large number of rollers of relatively small diameter. The rollers are arranged in such a way that the bags are also conveyed along an S-shaped path and are strongly compressed in the process.
  • the single figure shows a side view of the pressing device according to the invention.
  • the figure shows a pressing device 1 for bags provided with glued bottoms. These bags are first fed to the scale formation station 2 in the transport direction A and arranged in a scale-like manner in a generally known and therefore not described manner. After the formation of flakes, the bags are taken over by two press belts 3 lying one above the other, the bag bottoms between the press belts 3 being conveyed by clamping. For the sake of simplicity, the press belts 3, which are placed twice over one another, are shown in the figure only as a single line. The press belts 3 are guided or driven via rollers or rollers, not shown, which are mounted in the machine frame 4. On the way through the pressing device 1, the press belts 3 are guided over a pair of press cylinders 5, 6.
  • the press belts 3 loop around each of the press cylinders by at least 180 °. After the sacks have passed the press cylinders 5, 6, they arrive at the sack stacking station 7, in which the sacks which have now been produced are arranged in stacks. The stacks of bags can be removed from there.
  • the press belts 3 are arranged to rise.
  • the machine frame 4 is designed in a bridge-like manner, so that a free space 9 remains under the machine frame 4.
  • This free space 9 provides a passage for the operating personnel of the machine, so that it can get from one side to the other side of the pressing device 1.
  • the free space 9 is separated from the pressing device 1 by a separating device 10, so that unintentional reaching into the device by the operating personnel is prevented.

Abstract

L'invention concerne un dispositif de pressage (1) pour sac pourvu d'un fond collé, dans lequel au moins deux rubans de pressage (3) placés l'un au dessus de l'autre forment des zones de pressage dans lesquelles les zones de fond des sacs reposant l'une sur l'autre en se chevauchant peuvent être pressées. Les sacs peuvent être, au moyen des rubans de pressage (3), transportés entre une station de mise en chevauchement (2) et une station d'empilage de sacs (7), lesdits rubans de pressage (3) placés l'un au dessus de l'autre, qui sont au moins deux, pouvant être guidés par l'intermédiaire de moyens d'entraînement, de moyens de guidage et/ou de paires de cylindres de pressage (5, 6) montés dans le châssis de machine. L'invention se caractérise en se que les moyens d'entraînement, moyens de guidage et/ou paires de cylindres de pressage (5, 6) montés dans le châssis de machine sont disposés de telle sorte que les rubans de pressage (3) sont guidés par l'intermédiaire d'au moins une région en forme de pont du châssis de machine (4), ce dernier présentant un espace libre (9) accessible sous la région en forme de pont.
