Definitions

  • the invention relates to a can changer and a method for changing a can according to the preamble of the independent claims.
  • Can shifting devices are used in can changers, in particular as part of a textile machine, to move a full can away from a filling position and advantageously at the same time to move an empty can into the filling position.
  • the can changer places sliver in the can located there in a known manner until the can is full.
  • the lowering of the production speed from 500 m / min can be limited to around 100 m / min by means of a belt loop storage system.
  • the object of the invention is to increase the efficiency of the spinning preparation machine through the design of the can rest. This object is achieved by the subject matter of the independent claims. Advantageous further developments are given in the subclaims.
  • the can changer according to the invention comprises a receiving area which is designed to receive three cans with regard to its longitudinal extension.
  • the can changer further comprises a first can pusher which is designed to move along the entire receiving area and to pick up two cans.
  • the first can pusher is designed to pick up an empty can from a feed area and to push this empty can against a full can by moving it along the removal area and thus to move it into the area of a discharge path, the empty can remaining in a filling position as a can to be filled.
  • the invention is characterized in that the can changer has a second can pusher in the area of the discharge path of the receiving area which is designed to move the full can onto the discharge path.
  • the invention has the advantage that a very quick can change is possible, whereby, for example, the card only has to be reduced from a production speed of 500 m / min to 300 m / min when changing cans in combination with the belt loop storage. This increases the efficiency of the card with the draw frame integrated in the can depositing device.
  • the first can pusher preferably has a substantially elongated frame with an open longitudinal side.
  • the frame can be rectangular, curved or kidney-shaped. It is designed to accommodate two cans at the same time, so that the can pusher can move around the filling position along the receiving area.
  • the first and the second can pusher engage the cans at a height which is above the lower quarter of the can height ensures that the cans are secure against tipping.
  • the first and the second can pusher engage the can at the minimum height of 225 mm to 385 mm.
  • the second can slide can be actuated independently of the first can slide. This means that the second can pusher can push the full can onto the discharge path and at the same time the first can pusher can already move back without waiting for the end position of the second can pusher. This allows the shift cycle to be shortened.
  • the second can pusher can preferably be actuated transversely or orthogonally to the travel path of the first can pusher.
  • the different travel paths of the two can pushers increase the speed at which the cans are changed.
  • the second can pusher engages the cans at a height which is below the gripping height of the first can pusher, so that the latter can dive under the frame of the first can pusher.
  • an engagement height of the second can pusher on the can which is at least a quarter of the can height, can increase the stability of the can and make the can change process safer.
  • the can to be filled is held in the filling position by means of pivotable retaining elements.
  • the sliver deposit can already be started while the full can is being transported away and while the first can slide moves back into its starting position and picks up the new empty can. This can shorten the time in which the machine runs at a lower speed.
  • the retaining elements are arranged by means of supports at a height that is above the lower quarter of the can height, on the one hand the can can be held securely and secured against tipping over, on the other hand the first can changer can be moved into its own independently of the retaining elements and the can to be filled Move to the end position or its starting position.
  • the receiving area preferably has an open longitudinal side, at the first end of which a feed area with a transport path is arranged, and at the opposite end of the longitudinal side a discharge path is arranged.
  • the method according to the invention for operating a can changer has a receiving area with a first can pusher, one of which is a feed area Empty can is pushed into the first can pusher, and the can pusher moves the empty can into a filling position in which the can is filled with sliver as a can to be filled, while the first can pusher moves back to its starting position to pick up another empty can.
  • the method according to the invention is characterized in that after completion of the filling process, the further empty can is pressed against the filled can (full can) by means of the first can slide, and by moving the can slide the full can is moved into a position for removal via a discharge path.
  • the first can pusher thus moves around the filling position, which is occupied with a can to be filled for as long as possible, around the changing process and thus the shutdown of the
  • the full can is preferably transported onto the discharge path by means of a second can pusher. In this way the time to change the cans can be further shortened, since during this time the can to be filled is filled with sliver.
  • the process of changing the cans is further accelerated, since during the shifting time of the first can changer and second
  • Can changer the can to be filled is filled with sliver.
  • FIG. 1 an arrangement with a card and a downstream can changer
  • FIGS. 3 to 12 show a can changer in plan view with the process of can changing
  • FIG. 13 shows a can changer in side view.
  • FIGS. 1 to 13 is intended for use on a spinning preparation machine (e.g. a card, draw frame or combing machine) for cotton, synthetic fibers or the like.

  • the same features in the drawing are each provided with the same reference symbols.
  • the drawing is only shown in a simplified manner and, in particular, without a scale.
  • the device 100 it is possible to deposit a carded, drawn or combed fiber sliver 6 in cans 5a-5c.
  • the exemplary representation of a card does not restrict the use of the can changer to this, since combers and draw frames also have to adapt their production when changing cans.
  • FIG. 1 shows an arrangement 1 with a card 2 and a downstream can depositing device 3 and an associated can changer 100.
  • the card 2 produces a sliver 6 which is fed to a can depositing device 3 via a sliver store 4.
  • the can depositing device 3 can have an integrated drafting system and a subsequent depositing plate, which is designed in combination with a rotation device for a can 5b to be filled, to deposit the fiber sliver in the can 5b, for example in the form of a cycloid.
  • the can changer 100 has a receiving area 104 which, with regard to its longitudinal extension, is designed to receive an empty can 5a, a can 5b to be filled and a full can 5c, even if a maximum of two cans are located in the receiving area 104 over time.
  • the jug 5b to be filled is in a filling position 105 and is held in its position by four pivotable retaining elements 106.
  • the receiving area 104 is essentially rectangular and has a feed area 101 with a transport path on a longitudinal side that is kept open 102 and a discharge path 107 spaced therefrom. The cans are transported from the feed area 101 with the transport path 102 to the receiving area 104 and displaced in the direction of movement by 90 ° transversely into the filling position 105.
  • the can changer has a first and a second can pusher 110, 120.
  • the fact that the first can pusher 110 engages the cans 5a, 5b, 5c at a height that is above the lower quarter of the can height prevents the cans from tipping.

  • the first can pusher 110 does not move each can separately, but engages the empty can 5a, which presses against the can 5b to be filled or the full can 5c, so that both cans are shifted in position at the same time.
  • FIG. 2 shows a plan view of the part of the can changer 100 below the can depositing device 3. That is, the view of the one can 5b to be filled here is released.
  • the can changer 100 is shown in a state in which a can 5b to be filled, which is or has just been filled, is located on the receiving area 104.
