Definitions

  • the present invention relates to a method for transporting cans between fiber sliver processing or processing machines or devices, of which at least one of these machines or devices is assigned a can delivery point and a can delivery point, with a can transport means, between which the sliver be - or processing machines or devices can be moved in a predetermined way, and a device for performing such a method.
  • an automatic transport widget is the problem of the cans with a can-transporting means by a fiber ribbons treating or processing machine or such Vorrich ⁇ tung to bring another such machine or device.
  • the can transport means (wagons) are then shifted further by one pitch each so that the next cans can be pushed out.
  • This has the disadvantage that the can transport means must generally change its position when it leaves empty cans. ready before it can take up the full cans. This is not only cumbersome with regard to the corresponding drive and guide devices for the carriages, but also takes up a lot of space.
  • Another problem that occurs during automatic transport between two or more slivers of processing or processing machine or device is that these machine or devices can be of various types, so that the need for cans or the delivery of cans is also different.
  • the object of the present invention is to provide a method and an automatic can transport system which optimize the operation on and / or between the fiber bands processing or processing machines or devices and thus lead to a time and / or space saving.
  • the can transport means is loaded and unloaded simultaneously in one position on a machine or device processing or processing a fiber sliver.
  • time is saved since the cans are not removed from the can transport means only in the one working position of the can transport means and later, after the can transport means has assumed a new working position, new cans are loaded onto the can transport means are, but the Kannen ⁇ transport takes such a position in which loading and unloading can be carried out simultaneously.
  • Such a method inevitably also leads to a more compact design of the machines or devices in the area of their can delivery point and their can delivery point, since these are to be provided in such a relative arrangement that a similar movement enables loading and unloading.
  • Such a machine or device becomes particularly compact when the can transport means can travel between the can delivery point and the can delivery point, since then according to the invention the can transport means can be unloaded to one side and loaded from the other side.
  • the can transport means for the various machines or devices processing or processing fiber slivers which can be connected via the can transport means advantageously only one full / empty one is always used Jug loaded and at the same time unloading an empty / full jug. In this way, one and the same loading or unloading device for loading and unloading can be provided on each of these different slivers of processing or processing machines or devices.
  • the loading and / or unloading process takes place essentially without lifting and lowering the can.
  • the loading and / or unloading process is carried out with essentially only one translational movement of the can. It is particularly advantageous if separate loading and unloading devices on the individual sliver processing or processing machines or devices are unavoidable when the loading and / or unloading process is then carried out on the can transport means.
  • a can which is operated by a first fiber sliver does not have to be coordinated with one another so that the working methods of the machines or devices which process or process fiber slivers connected to one another via the can transport means. or processing machine or device must be brought to another fiber sliver or processing machine or device must be temporarily brought into a can store if the can on the other fiber sliver processing or processing machine or device is not at the moment is required, and is only called up from this can storage when this can is used on this other sliver processing or processing machine or device. This temporary storage of cans compensates for the different working speeds and the different cycle sequences on the different machines or devices.
  • a can between two fiber slivers that process or process machines or devices is checked.
  • This can be done in connection with temporary storage, but also independently of it.
  • a can storage unit in connection with a can inspection offers the advantage that a relatively large amount of time is available to subject the cans to a check, to remove damaged cans or to empty cans which for some reason have not been completely emptied ⁇ empty so that a pot always contains a single, uninterrupted sliver after it has been filled.
  • Such a method can be used both in connection with the simultaneous loading and unloading of the can transport means and independently of it. It can also be used regardless of how the can exchange is carried out on long spinning or twisting machines.
  • the check can take place at different points. Expediently, it does not take place on the sliver processing or processing machines or devices themselves, since this would presuppose that a large number of test points would have to be provided. In order to avoid this, it is provided according to the invention that the jug is either checked in the predetermined way of the can transport means or that the jug is removed from the predetermined way for the check, for example in a memory, where this check can then be carried out . In order to avoid impairment of the later work due to faulty or not completely empty cans, it is expedient to exclude the disputed cans from being forwarded to a machine or device that processes or processes these fiber slivers.
  • the can to be filled is advantageously checked for its filling status. This can be done in different ways, for example by scanning the inside of the can to determine the filling status by means of a sensor. However, it is also possible to weigh the pot to determine its filling level.
  • At least the can delivery point and the can delivery point of a sliver processing or processing machines or devices are arranged close to each other and on the way for the can transport means and that a can displacement means is provided, through which at the same time a can from the can transport means can be brought into the can delivery point and another can from the can delivery point to the can transport means.
  • the can delivery point and the can delivery point are symmetrical to that in the unloading or Can transport means located in the loading position is arranged.
  • a can storage device is arranged in a further advantageous manner between the two sliver processing or processing machines.
  • the can store temporarily holds cans that cannot be fed to the next fiber sliver processing or processing machine or device until the can provided in this can store is needed.

  • the cans delivery point and / or the cans delivery point are located at the end of the respective can store facing away from the filling head.
  • the empty cans at the can delivery point must be moved in the direction of the filling head and the full cans must be moved from the filling head in the direction of the can delivery point. It is therefore not necessary to provide movements in several directions of transport in the can stores.
  • the can offset means assigned to the filling head has a conveyor belt or a conveyor chain which expediently extends to the end of the can store.
  • a conveyor belt or a conveyor chain which expediently extends to the end of the can store.
  • at least one filling piece filling the intermediate space is expediently provided between the can storage and the conveyor belt or the transport chain.

It is therefore expedient that the can offset means assigned to the filling head, alone or in addition to a transport chain or a conveyor belt, also comprises a gripper which brings the can into the exact relative position with respect to the filling head.
  • the can store is advantageously arranged independently of a sliver processing or processing machine or device. This is particularly advantageous if the cans stored in this can store are to be delivered to a spinning or twisting machine which has a large number of work stations where there is no space for such intermediate storage, since otherwise the accessibility to the machine is impaired would be.
  • the path for the can transport means expediently forms a rail system consisting of three interconnected can circuits, a first can circuit having two sliver processing or processing machines and devices and the other two can circuits each processing or processing one of these sliver cycles or Devices and the can store included.
