Definitions

  • the invention relates to a device for packaging cylindrical strands from a number of cattle, preferably in each case the same number of disc-shaped workpieces arranged next to one another, in particular a lid made of metal, in a wrapping made of paper, to which the workpieces are fed from an upstream counting device via one or two conveyor troughs and the a wrapping station to the side of the or the conveyor troughs, a device for unrolling, feeding and cutting and gluing the wrapping paper, a device for transferring the strand or strands into the wrapping station and for closing the wrapping at the end, a folding device and a device for applying a sealing tape to the has folded end faces of the envelope.
  • Movable table is provided in the longitudinal direction of the strand, on which the cover strands are transferred from the conveying direction by means of a slide-guided gripping and clamping device.
  • the movable table with the cover strand held thereon is moved against a hanging apron of the wrapping paper and a fixed table of the device and, with partial wrapping in the paper wrapping, is pushed onto the stationary table of the device, a section for wrapping the strand is cut off the web and with the help of pressure elements, which partly encompass the strand, are wrapped in the paper wrapping after the one end section of the wrapping paper has been provided with a glue strip via a glue strip.
  • the strands encased in this way are transported further transversely to their longitudinal direction by the subsequent strand pushed into the wrapping station and thereby come under the influence of folding elements which act on the end face and fold the protruding sections of the paper wrapping in the manner of a cross-shaped base before, in the course of the further, transversely to the longitudinal direction of the strands-running feed the strands come between stationary pressure rails, which at the same time form the guide of a sealing adhesive tape on their sides facing the end faces of the strands, which adhesive tape is glued to the ends of the strands and is cut between adjacent strands with a knife.
  • the known device builds relatively wide by the laterally displaceable table and the laterally protruding stationary table for receiving the strands advanced transversely to their longitudinal direction until the envelope is completed, so that their placement in the course of the conveying paths, in particular of metallic lids, due to the space requirement leads to considerable difficulties.
  • the strands of the counted lids are sometimes so different in length that one of the two rails which engage on the end face and the associated folding elements cannot be used. If the second face cannot be folded automatically, the excess paper must be folded over manually.
  • the invention is based on the object, the device mentioned in the introduction so that it can be arranged with a very narrow design in the course of the conveyor troughs for the workpieces to be packed without any significant change in the conveying path of the workpieces and even with larger differences in length of the cylindrical strands a uniform Packing density of the workpieces is achieved within the strands.
  • the receptacles provided for accommodating the cylindrical strands in the device enable the strands to be transferred easily into the effective area of the clamping rails, which, by virtue of their arrangement which can be raised and lowered and laterally displaced in the raised position, make it possible to first convert a strand supplied to the device into a Transfer waiting position and clear the receiving channel or channels of the device for the next line.
  • fluctuations in the supply of the workpieces to the device in particular a temporarily higher or faster supply of the workpieces, can be accepted without having to adapt the working speed of the device to the supply of the workpieces to be packaged.
  • the device Since the strands are wrapped directly to the side of the respective receiving channels, the device is of narrow construction, so that it is used in the course of conveyor systems for such disc-shaped workpieces can be incorporated.
  • a uniform packing density of the workpieces within the strand is achieved by means of the pressure limiting buttons which can be moved towards the strand in the wrapping station.
  • the pressure limiting buttons which can be moved towards the strand in the wrapping station.
  • different longitudinal dimensions of the strands result with the same packing density.
  • the provided device which can be moved in the direction parallel to the longitudinal direction of the strand, for trimming the edge of the wrapping paper, its dimensions are adapted to the respective strand length in such a way that constant closure rosettes are produced on both sides of the strand.
  • These closure rosettes can be formed with the help of the folding fingers during the rotation of the strand with its covering in the wrapping station and can also be fixed in the wrapping station.
  • the entire arrangement is practically a single-station machine, in which the strand transferred to the drivable support rollers for wrapping is maintained while maintaining an adjustable axial pressure which is the same for all strands until the wrapping, including the closure rosettes, and their fixing is completed.
  • a particularly favorable and space-saving design is achieved by training with the features of claim 2.
  • the deep arrangement in the device makes it easier to insert the relatively heavy new supply rolls.
  • the gluing device and the unrolling device are easily accessible from the outside, as is the device provided below the wrapping station for applying and cutting off the sealing tape.
  • the device for trimming the edge of the wrapping paper is equipped with a cutting knife perforating the wrapping paper at a distance and parallel to the edge.
  • the wrapping paper is perforated at a distance from one end of the strand around the strand, so that when the sheath is subsequently removed for further processing of the workpieces, the tearing of the sheath along the perforation is made considerably easier.
  • Claims 10 to 12 describe the design of a device with a lowerable pressure bar provided above the wrapping station and its design. With this solution, the packaging is completely finished including the application of the fastener tapes in the wrapping station.
  • the device is designed so that the closure tape ends are pressed above the wrapping station, so that a new strand can be transferred to the wrapping station while the closure tape ends are being pressed, thereby increasing the cycle times of the device.
