Definitions

  • the invention relates to a method for automatic attachment of bags according to the preamble of claim 1 and one Device for this according to the preamble of claim 3.
  • EP-B-293615 It is known per se to automatically grab and close bags open to automatically attach it to a sack spout append and fill. This is how EP-B-293615 describes it a device for filling and closing paper gusseted bags.
  • individual sacks are made of suction cups taken from a package and moved between squeegees. This Squeegees are subsequently separated up to a stop hazards. Using the suction strips, the sack is opened so far that swiveling external grippers counteract the outer folds Able to press counterholders.
  • the pre-opened sack is then moved using a sled into a filling station under a stationary hopper moved and then gripped by swiveling grippers. While of the filling process, the carriage can move back to one to pick up a new sack.
  • a device for detecting individual, flat fabric parts preferably made of plastic according to EP-A-187 351.
  • Brushing is used here lifting or lifting individual tissue parts or tissue bags from done in a stack.
  • Each brush with its bristles is against the tissue to be detected can be pressed on and with it into the tissue part engaging bristles, in the direction transverse to the extension the bristles can be moved back and forth. In one direction of movement becomes the part of the tissue gripped by the brushes curious; excited. In the other direction of movement of the brushes give the Bristle the tissue part again.
  • the facility is included also applicable for opening sacks.
  • FR-A-21 07 176 shows a facility for roller application of fabrics on textile webs or the like.
  • a device for gripping foil bags describes the DE-AS 12 85 381 by means of grippers, wherein a bag to be opened on the top and on the bottom of two with adhesive strips provided roles is detected, then by pulling it apart to open the gripper.
  • the setup is comparative complicated.
  • a similar arrangement for opening and Guiding foil bags by means of grippers describes the DE-OS 14 86 061, which a method and an apparatus according to the Preambles of claims 1 and 3 disclosed.
  • the grippers contain gripper parts that are mutually movable and are provided with an adhesive and on the outside of the bags in the area of their opening act.
  • the gripper parts are each a device for Liability assigned, which is arranged so that a comb that can be pivoted against the adhesive bag surface represents. The arrangement is mechanically complicated and requires manual effort.
  • a device for opening foil bags according to GB-A 20 10 213, which includes gripping elements. These gripping elements are coated with nylon fabric, which in turn has hook-shaped elements and at the same time with is soaked in a gelatinous material.
  • the invention is therefore based on the object of a method and a device for automatically hanging bags, under Avoiding the disadvantages of the prior art indicated to create sacks made of different materials to grasp and access with simple means and reliable open to hang it on a sack nozzle.
  • sack materials are especially important also woven plastics, cotton and jute fabrics u. a.
  • the device for automatically attaching sacks exists from a gripping device 1 with gripping pin 2.
  • the gripping device 1 can be empty depending on the deployment position
  • Sacks 3 can be attached to a sack spout 4 by means of handling elements known per se, such as this z. B. is described in EP-A-522110.
  • the sack nozzle 4 is provided with bag clamps 5.
  • a high performance is given by the light construction.
  • the gripping pins 2 are equipped with self-renewing adhesion points 6. In the specific case, these are hot melt points with a lower number Adhesion to the gripping pins 2 as to the material of the bag 3rd
  • the device according to the invention can be described as follows:
  • An empty sack 3 is opened by means of a pair of gripping pins 2 a magazine not shown in detail in a lying position taken. Both gripping pins are with hot melt points as Detention areas 6 provided. When you grab the sack 3 it sticks Sack material at the points of detention 6 and simply by pulling apart the gripping pin 2 opens the sack 3 to the extent that after appropriate movement under the sack nozzle 4 attached to this and fastened by means of bag clamps 5 becomes.
  • the sack 3 stands with its bottom on a conveyor belt or the like
  • gripping pins 2 can be used simultaneously as well as one after the other to grasp and open the sack 3 on this.
  • the hot melt points tear by opening the gripping pins 2 from these and remain on the bag material.
  • the sack 3 is then in filled in the usual way and then closed. As well It would also be harmless to tear off the hot melt points from the sack material, however, in this case, the detention centers 6 would have to Gripping pins 2 are cleaned.
  • the hot melt points are used as self-renewing detention points 6 using conventional application equipment (e.g. nozzle application) gripping a bag 3 applied or they are inside the gripping pin 2 in a feed and heating device arranged.
  • the gripping pin 2 can optionally also include cooling, to achieve a quick cooling of the hot melt points.
  • the gripping pin 2 can be made from one reversible adhesive stamp 21 in a, also reversible Forcing sleeve 22 is made.
  • the glue point for the detention point 6 is applied by means of a nozzle 23, with rapid cooling. Also possible is to feed the adhesive through a hole in the adhesive stamp 21, which is more reliable but technically more complex.
  • the adhesive stamp 21 is liable, as described, via the adhesive point 6 on the sack 1 and by means of the reversible push-off sleeve 22 be separated from bag 1.
  • the gripping pins 2 could also be on clamped sack 3 remain to the filled sack 3 after the Detach from the sack nozzle 4 on a conveyor belt in a closing station respectively.
