Definitions

  • the invention relates to a method for automatically attaching bags according to the preamble of claim 1 and an apparatus therefor.
  • This relates in particular to the gripping and opening of open sacks, preferably those made from air-permeable materials, in order to hang them on a sack support and then fill them.
  • EP-B-293615 describes a device for filling and closing paper gusseted bags.
  • individual bags of suction cups are removed from a package and moved between suction strips. These suction strips are then moved apart as far as they will go.
  • the suction strips By means of the suction strips, the sack is opened to such an extent that swiveling external grippers can press the outer folds against the counter-holder.
  • the pre-opened sack is then moved by means of a slide into a filling station under a stationary filling funnel and then gripped by swiveling grippers. During the filling process, the carriage can move back to pick up a new bag.
  • the invention is therefore based on the object of providing a method and a device for automatically attaching sacks, which allows sacks of various materials to be gripped and opened with simple means and in a functionally reliable manner in order to attach them to a sack spout.
  • the invention is based on known ⁇ ich ways to create adhesive connections, such means instead of suction pads u. Like. Are used. Temporary adhesive connections are made between the bag and the gripping element for gripping and opening, in particular air-permeable and open, empty sacks. This allows the gripping elements to be detached from the sack material without any problems after the open sack has been attached and clamped on the sack spout, with the sack material being scarcely or not at all damaged by the choice of suitable pulling movements or speeds.
  • sack materials are primarily woven plastics, cotton and jute fabrics, among others
  • Fig. 1 shows a principle solution of the inventive solution
  • Fig. 2 shows a possible embodiment of parts of the gripping device.
  • the device for automatically attaching sacks consists of a gripping device 1 with a gripping pin 2. Depending on the position of the empty sacks 3, the gripping device 1 can carry out any appending movement on a sack nozzle 4 by means of handling elements known per se. B. is described in EP-A-522110. In a known manner, the sack nozzle 4 is provided with sack clamps 5.
  • the gripping pins 2 ⁇ are equipped with self-sealing adhesive points 6. In the specific case, these are hot-melt points with only less adhesion to the gripping pins 2 than to the material of the sack.
  • the device according to the invention can be described as follows:
  • An empty sack 3 is removed in a lying position by means of a pair of gripping pins 2 from a magazine (not shown in detail). Both gripping pins are provided with hot-melt points as detent points 6.
  • the sack 3 is gripped, the sack material sticks to the adhesion points 6 and by simply moving the gripping pins 2 apart, the sack 3 is opened to such an extent that, after a corresponding movement, it is attached to the sack nozzle 4 and fastened by means of sack clamps 5.
  • the sack 3 is preferably standing with its bottom on a conveyor belt or the like.
  • gripping pins 2 can act on the latter both simultaneously and in succession to grasp and open the sack 3.
  • the hot-melt points tear away from them by opening the gripping pins 2 and remain on the sack material.
  • the bag 3 is then filled in the usual way and then closed. It would also be harmless to tear off the hot-melt points from the sack material, but in this case the grip points 6 of the gripping pins would have to be cleaned in each case.
  • the hot-melt points are applied as self-renewing adhesive spots 6 by means of conventional application devices (e.g. nozzle application) before gripping a sack 3 or are arranged inside the gripping pins 2 in a feed and heating device.
  • the gripping pin 2 can optionally also include cooling in order to achieve a rapid cooling of the hot melt points.
  • the gripping pin 2 can consist of a reversible adhesive stamp 21, which is guided in a, also reversible, push-off sleeve 22.
  • the adhesive point for the adhesion point 6 is applied by means of a nozzle 23, with rapid cooling. It is also possible to feed the adhesive through a hole in the adhesive stamp 21, which is more reliable but technically more complex.
  • the adhesive stamp 21 adheres to the bag 1 via the adhesive point 6 and can be separated from the bag 1 by means of the reversible push-off sleeve 22.
  • the gripping pins 2 could also remain on the clamped sack 3 in order to guide the filled sack 3 after it has been released from the sack spout 4 on a conveyor belt into a closing station.
  • adhesion points 6 are feed-controlled adhesive sticks or adhesive rolls or also on Velcro strips which are known per se. However, the latter tend to become dirty and cannot be used for all materials.
  • the sack 3 or the entire sack stack 7 can be fixed in its position in order to achieve a safe separation, opening and movement of the sack 1. This can be done by means of a counterholder to an upper gripping pin 2 ', or also by means of fixing the sack stack laterally in front of the removal point 8. Technically, this can be done by means of a fold-down holder.

Abstract

L'invention concerne un procédé et un dispositif pour suspendre automatiquement des sacs, notamment aussi pour les saisir et les ouvrir. L'invention trouve une application, de préférence, pour les sacs ouverts perméables à l'air ou tissés. L'invention a pour objet de permettre, d'une manière simple et sûre, de saisir, d'ouvrir et de suspendre automatiquement à un ajutage de remplissage des sacs réalisés dans les matériaux susmentionnés. A cet effet, les tenons de préhension (2) de dispositifs de préhension (1) connus en soi, sont pourvus de points adhésifs (6) renouvelés automatiquement.
