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 device includes one of the ends of a film strip forming the carrying handle and gripping towards the carrying bag body folding feeder with two swivel arms, one each End of the film strip are assigned.
  • the swing arms are essentially one pivotable through 90 ° perpendicular to the plane of the film strip mounted to move back and forth and each have a clamping element for Clamp the respective end area of the film strip.
  • FR 2 576 246-A Another feed device for film strips serving as handles at Manufacture of carrier bags with handles is known from FR 2 576 246-A.
  • the swivel arms can be swiveled by 90 ° on a bearing plate. attached by means of a cylinder in the direction of that forming the carrier bags Plastic sheet is movable. To turn around when moving forward 90 °, the swivel arms are in a corresponding link guide guided.
  • the invention has for its object a device of the type mentioned to create a faster and safer feeder for the formation of loop-shaped Foil strips used for carrying handles and thus longer welding times or an increase in machine performance.
  • the loop handles by folding the strip ends form and securely attach to the bag body.
  • crank rod with the drive device in Connection
  • a servo drive designed as a primary drive having 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 intermediate wheel is arranged, which has a further drive means with planet wheels is in drive connection, the crank pin for articulation of the one Have ends of the crank rods.
  • the device according to the invention is for attachment to both pocket walls provided handles to be attached. Therefore, the crank rods are useful in pairs in each case above and below a double-layered, in essentially at right angles to the direction of movement of the plastic film 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 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
  • 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
  • Strip film web 3 extending axis 24 pivotally mounted. 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 swivel position II.
  • each are at the free ends of the swivel arms 23 Clamping elements in the form of clamping stamps lying on both sides of the strip of film 3 25, 27 provided, the upper clamp 25 by means of a essentially coaxially arranged adjusting cylinder 26 in the vertical direction can be raised and lowered, while the lower clamp 27 in the height is not adjustable.
  • the adjusting cylinder 26 can in the first Pivotal position I create a clamping effect, 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 33rd
  • 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. A coaxially sits 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 each 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. the upper clamp 25 is moved down by the adjusting cylinder 26. the 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 section of film 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 legs 21 of the grip loops 18 in the dashed lines in Figure 1 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 legs painted with a release agent.
  • the invention is not limited to the carrying handles be welded on. Rather, without leaving the core of the invention, the carrying handles are also attached to the pocket wall by gluing.
