Definitions

  • the invention relates to a circulating transport system for drawn goods baskets of a drum drawing machine, consisting of a self-contained conveyor track on which several drawn goods baskets can be fed one after the other to the loading station, fishing station, drainage station, inlet station and removal station, the functions carried out in the individual stations delayed or overlapping.
  • the known transport systems for drawn baskets are part of the drum drawing units, because several basket stations are always necessary for the economical drawing of pipes for the sequence of the work cycle. In order of time, it is necessary to first insert the basket into the circulation system, prepare the pipe for fishing and fish, run the bundle in front of the pulling unit and let it run up under the pulling drum after the pulling unit. Finally, the basket with the finished tube is either to be fed to a second drawing process or to be removed from the circulation.
  • unbound circulation systems In addition to so-called forced circulation systems, in which all baskets of wagons that are endlessly connected by chains, ropes, etc. pass through the stations, unbound circulation systems are known in which all drawn goods baskets individually pass through the various stations, for example on roller conveyors. Depending on the dimensions to be created, all of the drawn goods baskets in the circulating transport system pass through the stations once or several times.
  • the resulting time delay continues in subsequent moves to the finished dimension and extends the total pulling time. This increases the cost of pulling.
  • the present invention is based on the object of creating a circulation transport system of the type described at the outset and a working method for separating and introducing drawn goods baskets after a pipe ripper, with which the effectiveness of the system is increased significantly and the drawing time is also shortened taking into account inevitable pipe tears.
  • the conveyor track in the area between the discharge station and the inlet station has a branch for extending and retracting drawn goods baskets.
  • the branch is a conveyor track segment inserted into the conveyor track between the discharge station and the entry station and rotatable about a vertical axis, with which the direction of transport of the drawn goods basket that can be moved from the conveyor track to the conveyor track segment can be changed and that the conveyor track segment can be connected in alignment with either a conveyor for extending and retracting the drawn goods baskets.
  • the drawing drum is designated by 1, via which the drawing material 2 coming from the drain basket 6d is pulled through the drawing rings 4 and from which it is thrown into the inlet basket 6e arranged below the drawing drum. Details of this pulling device are state of the art and need not be described in more detail here.
  • FIG. 2 shows a conventional circulating transport system.
  • the roller conveyor 5 which is guided endlessly in a loop, seven drawn baskets 6a to 6f, shown in dashed lines, are placed in the exemplary embodiment and are transported in the direction of arrow 7.
  • the drawn goods basket 6a is placed on the roller conveyor 5 at the point shown, for example with the aid of a forklift, and transported by one work cycle to the position in which the drawn goods basket 6b is located in the drawing.
  • the drawn goods basket 6b and all other drawn goods baskets are transported by one position, so that the drawn goods basket 6b arrives at the fishing station 8, where the front end of the drawn goods is prepared for insertion into the drawing unit.
  • the drawn goods basket 6b is brought into the position in which the drawn goods basket 6d is located in the drawing. It is then located in the discharge station 9, from where the drawing material is wound through the drawing ring 10 onto the drawing drum 1 of the infeed station 11, which is located above the drawing material basket 6c which has now arrived below the drawing drum and which is intermittently with the others Has moved baskets, so that the drawing goods basket 6e located in the drawing within the infeed station is now in the position of the basket 6h.
  • the finished tube is removed from the system after a further or several passes, for example in a position in which the drawn goods basket 6h is located in the drawing.
  • the invention can be seen in Figures 3 and 4.
  • a conveyor track segment 14 which can be rotated about a vertical axis 12 in both arrow directions 13 and which interrupts the two conveyor track branches 5a, 5b.
  • this can be connected in alignment to a conveyor track section 15 or 16, which is intended for the retraction or extension of drawn goods baskets 6.
  • the operating cycle of the device according to the invention is comparable to that according to the prior art.
  • a certain number of tube turns are wound onto the drum and fixed by closing the pressure rollers, which are numbered 18 in FIG. 1.
  • the pulling process is continued until the end.
  • the full drawn goods basket 6e goes one step further and the drawn goods basket 6d emptied in the discharge station 9 is transported to the inlet station 11.
  • the time before the fishing piece is sheared off the pipe for the subsequent drawing process is sufficient to move the empty basket into the entry station without impeding the cycle sequence.
  • the drawn goods basket 6d emptied in the discharge station 9 is transported onto the conveyor track segment 14; the latter is rotated by 90 degrees, so that the empty basket can be moved into the inlet station under the drawing drum 1.
  • the basket 6d located in the drain station with the torn off residual tube bundle is transported directly and straight ahead onto the roller table 15 out of the circulation in the position shown in FIG.
  • the conveyor track segment 14 is rotated 90 degrees into the position shown in FIG. 4, and an empty drawing basket 19 deposited there is conveyed straight from the conveyor track 16 directly into the entry station.
  • the partially filled drawn goods basket 6e previously located there was transported one cycle further with all other baskets.
  • the drawn goods basket which has been moved out of circulation in this way and which is numbered 20 in FIG. 3, but corresponds to the drawn goods basket 6d, can be used independently of the drawing cycle, e.g. can be returned to production by forklift trucks at the feed station without the cycle sequence being adversely affected by moving the conveyor belt back.
