Definitions

  • the invention relates to a device for producing a carrier bag thermoplastic film with one on at least one of the pocket walls attached, designed as a handle loop handle made of thermoplastic Plastic film with a driven by a drive device, the ends of a the film strip forming gripping handle and towards the carrier bag body folding feeder and one of the ends of the handle with the Pocket wall firmly connecting welding device.
  • the invention has for its object a device of the type mentioned to create a faster and safer feed for the formation of loop-shaped Foil strips used for carrying handles and thus longer Guaranteed welding times or an increase in machine performance.
  • the feed device one each associated with one end of the swivel arm forming the handle strip having a substantially perpendicular to the plane of the film strip extending axis between a first lying in the area of the film strip Pivotal position and a second, essentially offset by 90 ° Pivotal position is pivotally mounted back and forth and each one assigned to the respective end region of the film strip or the handle Has clamping element that in the first pivot position of the swivel arm in a Clamping position and in the second swivel position of the swivel arm in a release position is feasible.
  • each swivel arm via an associated crank rod with the drive device in Connection is made, which is preferably a servo drive designed as a primary drive has, via a first drive means with a on a main drive shaft seated drive wheel is connected to the coaxial one on the main drive shaft seated idler gear is arranged with another drive means Orbital wheels in drive connection, the crank pin for the articulation of each have one ends of the crank rods.
  • crank rods are expedient in pairs each above and below a double-layered, essentially perpendicular to the direction of movement of the plastic film sheet forming the carrier bags movable film strip track arranged.
  • the double-layer film strip between a fixed Upper knife and a movably arranged lower knife of a strip cutting device passes through can be cut from the film strip web Cut two strips of film each corresponding to a handle.
  • the device shown in Figures 1 and 2 for producing a carrier bag made of thermoplastic plastic film has a feed device 1 and a drive device 2 on.
  • the strip film 3 becomes one
  • Strip cutting device 9 supplied, which a fixed upper knife 11 and a has substantially vertically movable lower knife 12. With the help of the strip cutter 9, a film strip 13 can be separated from the strip film 3 become.
  • An essentially horizontal one serves to guide the film strip 13 arranged guide plate 14 and lateral guide plates 15, 16 fastened thereon.
  • a guide table 20 (FIG.
  • the actual feed device 1 has above and below the strip film web 3 pivot arms 23 each arranged in pairs, which are essentially identical are trained so that only one is described in detail below.
  • everyone Swivel arm 23 is about a substantially vertical to the plane of movement
  • the swivel movement takes place essentially between one lying in the area of the film strip 13 first pivot position I and a substantially 90 ° offset to it second pivot position II.
  • Each are at the free ends of the pivot arms 23
  • a clamping effect can be generated as a result of in the guide plate 14 arranged, corresponding to the pivoting movement of the pivot arms 23rd curved and in the area of the first swivel position of the swivel arms laterally open guide recesses 28 between the upper clamp 25 and the lower clamp 27 of the film strips 13 are clamped directly can.
  • the ends of the film strip 13 in the actual handle position flipped, in which the legs 21 of the handle 18 in run essentially parallel to one another, with a weld, for example an oval weld 29 using the welding device shown in Figure 2 31 can be connected to the pocket wall.
  • the welding device consists of known manner from an upper welding head 32 and a lower welding head 33.
  • the feed device 1 is in each case via a Crank rod 34 connected to the drive device 2.
  • the drive device 2 itself has a drive motor 35 designed as a servo drive, which has a first drive means 36 communicates with a main drive wheel 37 which is on a main drive shaft 38 is seated. Sits coaxially on the main drive shaft 38 Intermediate wheel 39, which has a further drive means 41 with planet wheels 42, 43, 44 in Connection is established, crank pins 45 being arranged on the planet wheels 42, 43, at which the one ends of the crank rods 34 are articulated, with their engage the other end in an articulated manner on the swivel arms 23 via a joint 46.
  • This separated film strip then lies, as can be seen from the drawings, in the region of the guide plate 14 first in the area of the swivel position I of the feed device 1.
  • the clamp 25, 27 are brought into their clamping position, d. H. of the upper clamp 25 is moved downward by the adjusting cylinder 26. of the lower clamping punch 27 is always in the arcuate guide recess 28 held so that the upper clamp 25 on the lower clamp 27th can be driven.
  • a film section is corresponding the width of a carrier bag wall has been moved into the receiving position.
  • the drive device 2 and the crank rods 34 respectively move the swivel arms 23 from their swivel position I into the swivel position II, the leg 21 of the handle loops 18 in the in Figure 1 with dash-dotted lines shown location.
  • the welding device 31 then passes through Moving the welding heads 32, 33 a corresponding weld, z. Legs Oval weld 29 reached. So that z. B. on the inside of the pocket wall subsequent welding does not cause the grip loops to stick together the ends of the inn are painted with a release agent.
  • the invention is not limited only to the carrying handles be welded on. Rather, without leaving the core of the invention, the handles are also attached to the wall of the bag by gluing.
