Definitions

  • the invention relates to a transport device for guiding a material web from an inlet side to an outlet side in a packaging machine with transport chains and chain wheels arranged on both sides of the web for guiding the transport chains, in which each transport chain has chain links and associated holding clips for gripping an edge of the material web a fixed bracket member connected to the associated link and a movable bracket member, and a compression spring for biasing the movable bracket member to the closed position, and a cage member engageable with the movable bracket member along a track portion of the chain.
  • Such a transport device is known from DE-OS 22 24 854.
  • the fixed clamp parts are fixedly connected to bushings in which a bolt which is fixedly connected to the movable clamp parts is slidably guided in such a way that skewing of the bolt and thus the movable clamp part is avoided.
  • a transport chain with lateral angle plates attached to the chain links is known, the lateral angle plates having horizontal bolts which engage in elongated holes on the movable bracket part.
  • the interacting with such a transport chain, designed as thrust washers have pocket-like recesses which cooperate with the chain links so that the movable bracket parts are raised and lowered obliquely.
  • the clamping jaw of the movable clamp part is not lowered vertically onto the clamping jaw of the fixed clamp part and can thereby cause the material web to shift when it is closed.
  • both the structure of the chain links and the thrust washer are complicated.
  • the object of the invention is to provide a transport device of the type described at the outset which enables unimpeded insertion and secure gripping of the material web even when the width of the material web fluctuates due to the production process. It is also intended to prevent the material web from being pushed against the center of the packaging machine when it is gripped.
  • a transport device of the type described at the outset which is characterized according to the invention in that the overrun element is designed such that the movable clamp part is lifted substantially perpendicularly from the fixed clamp part in a first section of the running track part and in a second part adjoining it Section of the track part is additionally moved laterally away from the material web edge to be gripped relative to the fixed clamp part.
  • the invention is used in particular in a deep-drawing packaging machine which is generally designated by the reference number 1 in FIG.
  • This has a machine frame 2, on the input side of which a roller 3 with foil material is arranged, from which the material web 4 is drawn off from this foil material and is guided via a deflection roller 5 to a transport device 6.
  • the transport device 6 has, in a known manner on both sides of the material web, enclose chain runs 7, which are guided and driven at their deflection points via chain wheels. Holding clips are fastened to the chain links in a known manner, with which the material web 4 is gripped laterally and guided through the processing stations of the thermoforming packaging machine. On the exit side, the material web is released again by the holding clips.
  • the transport chains 8, 9 run on chain wheels 10, 11, which are mounted in the machine frame 2 in a known manner by means of roller bearings and axles.
  • the right and left chain center with the associated drive devices are mirror-symmetrical. Therefore only one page is described.
  • each chain link has a retaining clip 12.
  • This has a fixed clamp part 13 in the form of an angle plate riveted onto the bolt 14 of the chain link.
  • a movable clamp part 15 is provided, which is designed in the form of a box-shaped clamp with a movable clamping jaw 151, side walls 154, 155 and abutments 156, 157 bent over at the bottom.
  • the fixed clamp part 13 has a fixed jaw 131 with a bore 132.

  • a fixing bolt 152 is provided which is riveted to the movable jaw, which is arranged so that it is aligned coaxially with the collar bush 133 in the closed state of the retaining clip, and the outside diameter of which is selected that it can slide in the flange bushing. Its length is chosen so that it is first a path in the flange bushing and then emerges from this.
  • the fixed bracket part 13 has two side parts 134, 135 in the form of substantially at right angles to the front bent tabs, in each of which guide pins 136, 137 are riveted.

  • the slide is held by the groove 71 near the sprocket 10 and the movable jaw 15 is returned perpendicular to the fixed jaw 131.
  • a predetermined curve shape of the groove 71 was described above as an example. However, it is the advantage of the third embodiment that the curve shape of the groove 71 is freely selectable and thus the pivoting or tilting of the movable bracket part 15 depending on the angular position of the holding bracket 12 is freely controllable by an appropriate design of the groove 71.
  • the obliquely arranged thrust washer 30 or the shape of the annular groove 71 ensures that the movable jaw 151 is first lifted vertically from the fixed jaw 131, then pivoted outwards or towards the sprocket or away from the material web, then into one position swung back vertically over the fixed jaw and lowered vertically onto it.
  • the material web can be easily gripped by the holding clip 12 without being pushed from the lateral holding clips to the center of the packaging machine.
  • both the thrust washer and the slide device described in connection with FIGS. 7-9 can be used in connection with each clamp, which allows the movable clamp part to be raised and pivoted.
