Definitions

  • the invention relates to a spool transfer device for forwarding spools between a spool delivery point, in particular a spool-forming machine, and a spool removal parts, in particular a spool-processing machine or a transport or. Collection system.
  • Devices of this type are used in particular for forwarding cylindrical or conical bobbins produced on cross-wound machines, open-end spinning machines or double-wire machines.
  • Such coil-forming machines generally have a buffer for a certain number of completed coils at the outlet.
  • the buffer consists, for example, of a trough in which the coils, in particular on a conveyor belt, are kept in a row ready for removal.
  • Robots are used as a means of transport between the bobbin delivery point and the bobbin take-off point, which pick up the individual bobbins one after the other at the delivery point and deliver them to the take-off point. In this way, the coils are passed on carefully and without the risk of damage, but the robots work relatively slowly, so that they can only serve a few delivery points at a time.
  • a coil removal parts is achieved with swivel conveyors, which can translate several coils at the same time on a swivel arm designed as a fork.
  • a swivel conveyor used in practice, several, e.g. to tip four or five bobbins out of the buffer at the exit of the bobbin-forming machine onto the swivel arm which is moved parallel to the row of bobbins provided. Then the swivel arm together with the coils lying on it, e.g. swiveled by 90 °, horizontally and moved laterally to the removal position so that the coils lying on the swivel arm can be tilted sideways from it.
  • the swiveling conveyors work faster than the aforementioned robots, which only translate individual coils, but several swiveling and lifting movements are required in each work step, so that the expenditure of time is still considerable; in addition, the swivel conveyor can only be used if the construction of the bobbin take-off point enables several bobbins to be tilted into the storage position at the same time.
  • the invention has for its object to provide a bobbin charger, in particular for conical cross-wound bobbins, which, like the robot which only transports individual bobbins in succession, acts as a connecting link between all types of bobbin-forming
  • Machines and all commonly used coil removal points is suitable, but works so quickly when translating the coils that the investment in relation to the robots that translate the coils one after the other is considerably reduced.
  • the solution according to the invention is characterized for the bobbin transfer device of the type mentioned at the outset by a loading bridge to be adapted in terms of height and inclination to the path between the bobbin delivery point and the bobbin removal point for a continuous transfer, the bobbin upstream side of the bobbin delivery point and the bobbin discharge side of the bobbin removal point and a loading bridge , controlled by a central material flow computer assigned to the spool delivery point and / or removal parts into the respective transfer position of the drive unit to be driven.
  • the invention creates a loading bridge as a straight connection for continuous translating coil-by-coil directly to the intended storage position at the coil take-off point. After the bridge has been aligned, the bobbins can "run through” smoothly from the delivery point to the removal point.
  • This continuous flow principle provided according to the invention enables an extraordinarily high clearing performance because coils running out of the coil-forming machine go directly to the take-off point,
  • a particular advantage of the invention is that the coils with the sleeve standing, lying with the end face forward or - especially in the case of cylindrical coils - are to be transported in a train on the loading bridge in a rolling manner.
  • the loading bridge is designed, stored or driven in such a way that it must be adapted to the delivery position of each coil-forming machine and the position of the coil take-off point provided in each case — if necessary, storey — for storey.
  • the bobbins can be removed from delivery machines which have a removal removal or two (or more) conveyor belt removal points.
  • the loading bridge according to the invention is suitable for moving over both superposed floors as well as adjacent channels of an acceptance system designed, for example, as a trolley or trolley.
  • Usual trolleys or trolley systems can also be operated optionally on one or the other end by using several coils, e.g. Up to five coils can be inserted in a row in the memory channels.
  • the loading bridge can be adjusted about an axis that is height-adjustable on the drive unit
  • each longitudinal end - i.e. the spool upstream side and the spool outflow side - of the loading bridge is assigned a pair of cylinders driven in the same direction, the two lifting cylinder pairs being actuated independently of one another in such a way that the entrance and exit of the loading bridge correspond exactly and with the respective positions of delivery and removal points are essentially adapted to a lifting cylinder movement.
  • the loading bridge on the drive unit should have a basic position or driving position in which it takes up as little space as possible when moving the drive unit from one machine to the next machine or into the preparation position.
  • the spools held ready at the delivery point are handed over, for example, either by a conveyor belt, by designing the delivery point as a roller conveyor or slide, or with the aid of a pusher assigned to the loading bridge.
  • the loading bridge together with the drive unit carrying it, is controlled by a central material flow computer, which preferably includes
  • the central computer should be programmed in such a way that it orders the drive unit and, if necessary, the respective bobbin take-off point, in particular a trolley or trolley system, to a bobbin delivery point whose buffer is filled with finished bobbins.
  • the computer should also be supplied with information about the respective coil type and the coil diameter as well as the position (standing, lying or rolling) in which the individual coils are to be transported.
  • the loading bridge After positioning the drive unit between the delivery point and the acceptance point, the loading bridge is extended and aligned between the delivery point and the respective acceptance point. It is also adapted to the requirements resulting from the type, size and location of the respective coils.
  • the lock, the pusher and / or a conveyor belt at the delivery point or at the loading bridge are actuated in such a way that a predetermined number of bobbins in one go, that is to say bobbin-by-bobbin, are to be transferred immediately.
  • This process should also be controlled directly or indirectly by the central computer.
  • the latter should finally be programmed in such a way that it automatically positions the loading bridge at the next storage compartment after the filling of a compartment in the take-off point for the acceptance of further coils.
  • the channel of the take-off system to be filled with coils must be aligned with the longitudinal direction of the loading bridge before transfer. This generally assumes that a trolley or trolley must be swiveled 90 ° at each loading point in order to align the longitudinal directions of the coil channel in the trolley or trolley on the one hand and the loading bridge on the other.
  • the described additional pivoting movement of the coil removal system can generally be carried out without any problems and with little expenditure of time since the pivoting only has to be carried out once for the entirety of the coils to be transferred.
  • it can be difficult to place the generally relatively elongated trolley or trolley on the machine.
  • it is provided according to a further invention to provide a space for several buffers to be arranged in a straight row between the bobbin discharge side of the loading bridge and the bobbin take-off point on the trolley or trolley, from which the bobbins are to be discharged to the side.
  • a buffer of the type specified should be inclined in a substantially horizontal plane, in particular
  • the buffer pusher for ejecting several coils - preferably for simultaneously ejecting the coils - should each have one level of a coil removal system.
  • the coils arrive, one by one, into the buffer, preferably with the help of a further pusher, individually as they arrive.
  • a further pusher preferably with the help of a further pusher, individually as they arrive.
  • the buffers can be used to fill several superposed tiers of a bobbin removal system with bobbins.
