Definitions

  • the invention is in the field of packaging technology and relates to a method and a device according to the preambles of the corresponding independent Claims.
  • the method and device according to the invention are used for packaging of flat objects or of small groups of flat objects with the help of a packaging material that is fed as an almost endless web becomes.
  • the packaging material is, in particular, weldable from a roll Plastic film.
  • a well-known, continuous process for packaging individual printed products or of small groups of printed products using plastic film from a roll consists of a flow in which the products to be packaged are essentially aligned parallel to the conveying direction one behind the other and spaced apart are encouraged to run between two film webs or with a film web merge and this to lay the products of the flow. Then the film webs or the film web are welded parallel to the conveying direction and in the distances between the products across the conveying direction also welded and cut.
  • Such a method and a corresponding one Devices are described for example in publication EP-1188670 (F533).
  • a corresponding device is described in more detail in the publication DE-3838985 (MAN) described for batch operation.
  • MAN plastic film is stretched from the roll in a zigzag pattern, whereby a predetermined Number of V-shaped pockets open on three sides, in which to packaging printing products are positioned. Then the bags separate from each other separately to close the products positioned therein and to the open ones welded on three sides and released from the device. Only then will again a predetermined number of pockets are formed and the procedure is repeated. For every a pocket to be formed in a batch is essentially the same sub-device provided and all sub-devices are operated simultaneously.
  • the invention has the task of a method and a Device to create the continuous packaging of flat objects with the help of a packaging material fed as a virtually endless web serve and compared to corresponding methods and devices according to Prior art are simpler and in particular also in a simple manner Have it adapted to different formats of the objects to be packaged.
  • the packaging material becomes continuous fed, advantageously such that the width of the quasi-endless path of the Packaging material is aligned substantially horizontally. Then it will Packaging material taken at regular intervals from above and the distances then reduced between the gripping points, the packaging material between the gripping points, for example by gravity (if necessary supported with additional measures) is deflected downwards. It forms such a pocket string with arranged between the gripping points on three sides open and closed pockets on one side, those of the closed Side opposite, open pocket sides is directed upwards.
  • This pocket string is held at the gripping points past a loading position transported where an object to be packed in each pocket of the pocket string or a corresponding small group of flat objects is advantageously supported by gravity, that is, from above the open pocket side opposite the closed side. While the filled bags are transported further, they are separated from each other and then closed. For closing, the pockets are between, for example Closing elements equipped with welding jaws are positioned, which advantageously take over the bags and promote them further.
  • the method described above can also be carried out when the packaging material is gripped from below for the formation of the pocket strand.
  • the packaging material can also be fed in any position and between the grab points by appropriate measures (e.g. Air flow) relative to the gripped surface in one direction or the other are deflected, the loading of the pockets then also being set up accordingly is.
  • appropriate measures e.g. Air flow

  • the gripping elements of the conveyor system are designed to grip the packaging material from its one surface and without the subsequent pocket formation and the loading of objects to be packed in the way his.
  • the gripping elements are arranged, for example, on gripper rods, the Gripper bars project beyond the width of the packaging material on both sides and their Ends in guides that run parallel to the longitudinal edges of the packaging material stored and driven accordingly.
  • To support the gripping elements when gripping the packaging material there may be support elements provided which are conveyed synchronously with the gripping elements and which attacking from the surface of the packaging material other than the gripping elements, Insert the packaging material into the gripping elements before they are closed become.
  • the means for closing the pockets has pairs of closing elements, which can be brought into an open and a closed position, one after the other are eligible for funding and for the sealing function, for example with welding jaws are equipped.
  • the means for closing is advantageously equipped around the pocket strand or possibly already separated from the pocket strand Bags before or after loading and separating the bags to take over from the pocket strand from the grippers. For this function they are Closing elements optionally equipped with fixing elements with which they Can hold packaging material, and / or are a means of holding the bottom of the bag intended.
  • FIG. 1 and 2 show a first, exemplary embodiment of the method according to the invention on the basis of a very schematically illustrated device.
  • Figure 1 shows the device from a viewing direction parallel to the width of the packaging material,
  • Figure 2 with a viewing direction perpendicular to the gripped surface of the packaging material.
  • the general conveying direction (F) runs essentially from left to right in the figures, the packaging material 1 being fed, for example, from a roll 2, in order then to a gripping zone I, a pocket formation zone II, a loading point III, a transfer zone IV, a separation point V to pass through a closing zone VI and a discharge point VII, the fully packaged objects being released from the device at the discharge point.
  • the conveyor system 3 through the action of which the packaging material from the gripping zone I is promoted to the transfer zone IV, for example, a couple of parallel guide rails 4, in which the ends of gripper bars 5 can be conveyed at varying intervals, can be rolled or slidably mounted and are driven accordingly.
  • On the gripper bars 5 are, for example, in the middle Gripping elements 6 are arranged which cooperate with support elements 7 in the gripping zone I.
  • the support elements 7 are on their own rotating conveyor 8 arranged. Their distance corresponds to the distance that the gripping elements 6 in the gripping zone I have from each other, or the length of packaging material that must be separated from the virtually endless web for each packaging to be created.
  • the Promotion of the support elements 7 is synchronized with the promotion of the gripping elements 6, such that one supporting element 7 on one side of the packaging material 1 occupies the same position as a gripping element 6 on the other Side of the packaging material. Furthermore, the support elements 7 are transverse to it Movable direction of conveyance, from a first position in which it is not on the packaging material 1 act in a second position in which they engage in the gripping elements. By moving the support elements from the first to the second Position, the packaging material is pushed into an open gripping element 6.
  • the distances between the gripping elements 6 reduced and the packaging material extending between the gripping elements 6 1 optionally actively deflected against one of its surfaces, such that pockets 1 'are created which all protrude onto the same side of the gripping elements.
