    • D01H9/185—Transporting cans

Definitions

  • the invention relates to a can transport trolley with a can changing device for changing empty sliver cans at the spinning positions of a spinning machine against filled sliver cans with a turntable on which the cans stand and in which the rotary table can be delivered to the can changing location in such a way that a can change can be carried out with the can changing device.
  • Can transport trolleys are used to facilitate and automate can transport and changing empty cans for full cans at the spinning stations and empty cans for full cans at the loading stations on the lines.
  • a can transport trolley with a turntable is known.
  • the cans each have predetermined storage locations on the rotary table, all of which are equidistant from the rotary axis of the rotary table.
  • the can changing device of the can transport vehicle has a specific can unloading position and a specific can unloading location.
  • this can transport trolley and the can changing device it is only possible to change cans set up in rows at the spinning positions of a spinning machine. This means that only very small cans can be positioned at the spinning positions that empty very quickly.
  • the can transport trolley according to the invention has a further parking space for a can next to the turntable, on which the filled sliver cans to be delivered and the cleared empty cans are located.
  • the sliver can standing in the first row, which releases the sliver and stands in front of the empty can, can be temporarily parked on the parking space next to the turntable replace the empty jug from the second row with a filled jug.
  • the sliver does not need to be withdrawn from the can on the additional storage space.
  • the way is cleared for an automatic jug change of the empty jug in the second row.
  • the sliver can from the first row, temporarily parked in the additional storage space of the can transport wagon, is returned to its old place.
  • the sliver cans advantageously retain the locations once related to the respective spinning station. This means that the sliver cans can be automatically changed at any time in relation to their assigned spinning station.
  • the can transport trolley has three slots for sliver cans on the rotary table, each of which occupies a 120 degree sector around the central axis of the rotary table.
  • the arrangement of the cans in a triangular shape on a turntable enables optimal use of the footprint with a correspondingly narrow dimensions of the can transport trolley.
  • the can contour which extends beyond the contour of the can transport carriage when the turntable and thus the cans are rotated, only slightly exceeds the dimensions of the can transport carriage.
  • the turntable is set so that the space on the turntable that corresponds to the space for the company
  • the jug that dispenses the tape is adjacent and faces the cans on the spinning machine, there is an empty space.
  • this intended position of the turntable it is possible to either immediately pick up an empty jug from the first row or to place a sliver-dispensing jug from the first row on the space provided for it during the jug change.
  • an empty jug from the first row has been placed on the turntable, it only needs to be rotated by one division of a sliver can to position a filled jug for storage.
  • the can transport trolley can continue driving immediately. Before the trip, he can turn the empty jug into such a position by means of the turntable that there is again an empty parking space on the turntable on the side of the can transport carriage opposite the spinning machine.
  • the empty can is placed on the empty space on the turntable, which then rotates into a position such that a filled sliver can is ready for replacement. After depositing this filled jug in the second row, the canister that has temporarily stored fiber sliver is moved back to its old location via the empty space on the turntable.
  • a telescopic slide with at least one gripping element is provided on the can transport carriage as the can changing device.
  • This carriage is arranged above the cans and can be moved transversely to the direction of movement of the can transport carriage.
  • the telescopic design of the carriage enables space-saving installation in the can transport carriage so that no parts protrude beyond the contour of the can transport carriage. Nevertheless, to handle the cans in the second row, it is possible to extend the carriage over a distance of at least two diameters of the cans.
  • the gripping element is designed for the vertical lifting and lowering of the cans.
  • gripping fingers can be provided which allow one-sided gripping and simultaneous centering of the cans during handling.
  • a gripping element is provided on both sides of the slide, which is designed for gripping the cans at their upper edge and for vertical lifting and centering on centering elements on the can changing device and for lowering and parking the cans in the respective parking spaces.
  • the can changing device is arranged to be movable above the rotary table. It is arranged so that it moves above the parking space in the transfer position on the turntable, which is adjacent to the space for the empty jug.
  • the can changing device is dependent on the spinning position and can be moved in a can-oriented manner. This makes it possible to carry out a can change at each spinning station in a targeted manner with a minimum of can movements.
  • a spinning station requests the can transport wagon to carry out a can change
  • the spinning station sends a detection code wirelessly or via induction lines or via fixed signal lines.
  • a microprocessor in the can transport trolley recognizes its destination.
  • the can transport trolley positions itself in front of the requesting spinning station.
  • the request and the positioning is state of the art and known for example from DE-OS 38 31 637.
  • the can transport carriage Based on the code sent by the spinning station, the can transport carriage recognizes whether the can to be replaced is in the first or in the second row. The can change program then runs accordingly. If the jug is in the first row, the replacement takes place in a known manner, as is known for example from DE-OS 38 31 638. If the jug is in the second row, the jug in front of it must first be temporarily parked on the space for the sliver-dispensing jug.
  • a device for moving the fiber-dispensing can from the turntable to the parking space provided for it and back.
  • the workflow of this device is coordinated with the workflow of the can changing device.
  • This facility can be simply constructed.
  • a gripper claw for example, is sufficient to move the cans back and forth.
  • the movement of the can changing device can be limited to a linear reciprocating movement.
  • the can changing device as a whole can additionally be moved in the longitudinal direction of the can transport carriage. This makes it possible to place the sliver-dispensing jug on the turntable with one and the same means of transport without a stopover immediately on the space provided for it for a temporary change of location.
  • Parking space for the sliver-dispensing can provided at least one guide element for the sliver running off.
  • the jug When the jug is moved to the parking space, the jug is moved laterally away from the spinning station, so that the sliver is no longer fed in in the direct direction of the spinning station.
  • a guiding element ensures that the sliver runs securely in the direction of the spinning position and the running sliver is kept out of the range of motion of the can changing device.
  • the change of the cans on the spinning machine and at a can loading station can easily be carried out with the can changing device on the side of the can transport carriage on which the parking space is provided for the temporary reception of a sliver-dispensing can.
  • the can changing location assigned to the spinning machine and the can changing location assigned to the can loading station on the can transport trolley are each arranged on the broad sides opposite one another. This configuration of the can transport vehicle helps to avoid a space-consuming and time-consuming change of direction of travel of the can transport vehicle if these two locations are not on the same side of the travel path of the can transport vehicle.
  • the can changing device is arranged to be movable over the two can changing locations.
  • the can transport trolley recognizes whether it is opposite a spinning machine and has to carry out a can change there, or whether it is located at the can loading station and should replace the empty cans with filled cans according to the location of the can changing locations the can changing device in each case to the corresponding side and carries out the intended can changing.
  • Fig. 1 shows the spinning station 1 of an open-end spinning machine S, which consists of a plurality of spinning stations lying side by side.
  • the can 5, seen from the front of the spinning machine S, has run empty. Therefore, no thread is drawn from the draw-off roller 7 from the draw-off roller pair 8 and wound onto the package 10 via the thread guide 9. Because of the lack of sliver, a thread breakage has occurred and the bobbin holders 11 have lifted the package 10 from the winding roller 12.
  • sliver 13 is drawn into the compressor 14 of the spinning box at the spinning station located behind it in its spin box.
  • the sliver 13 slides over the deflecting rod 15.
  • a can transport carriage 16 is positioned in front of the spinning stations.
  • the can transport carriage consists of a chassis 17 which has four flanged wheels 18a to 18d on the side facing the spinning machine, as can be seen in FIG. 2. Two flanges are combined to form a pair of flanges 18a, 18b and 18c and 18d.
  • each pair of wheel flange rollers is attached to the chassis in such an articulated manner that narrow curve radii can also be driven through.
  • the flanged rollers 18a to 18d run on a rail 19 which runs along the spinning machine and an exact track Management of the can transport carriage allowed.
  • the pair of flanged rollers 18a and 18b is driven by a motor 21 via a transmission 20.
  • the can wagon is supported on two further wheels 22 and 23.
  • the rear part of the can transport carriage is omitted in FIG. 1, so that a view of the can changing device and of the rotary table with the cans provided is possible.
  • a horizontally arranged turntable 24 is located above the chassis 17 of the can transport carriage 16. It can be rotated about a vertically arranged axis 25. On the axis is a gear 26, which is wrapped by an endless toothed belt 27. This toothed belt also wraps around a drive wheel 28, as can be seen in FIG. 2, which is driven by a motor 29.
  • the turntable has the shape of an equilateral triangle.
  • a parking space A, B and C in a sector of 120 degrees is provided in the area of each corner.
  • the corners of the triangle are cut so far that the cans located on the three positions A, B and C each protrude with their lower edge over the surface on the turntable.
  • stop strips 30 To position the cans on the respective parking spaces, they are separated from one another by stop strips 30.
  • stop rollers 31 are arranged for precise positioning of the cans at such a height that they do not fall over when they are placed on the turntable or when the turntable is turned.
  • the rotary table is loaded with two cans filled with fiber sliver after the empty cans brought there have been cleared away.
  • the turntable 24 with the two cans located thereon is set such that the cans are arranged one behind the other in the direction of travel and the two parking spaces face the front of the spinning machine.
  • the can transport carriage has already been requested by a spinning station and has positioned itself in front of the corresponding can. 1 and 2, the situation in the can change sequence is shown, in which a can, which is positioned below a spinning station, is to be taken over to the opposite empty space on the rotary table.
  • the filled cans 32 and 33 which are brought up from a can loading station and which are in the positions A and B of the rotary table 24, have been rotated counterclockwise about the axis 25 from their transport position, as the arrow 34 symbolizes.
  • the rotation took place by 120 degrees, so that the empty parking space C on the rotary table 24 came to a position opposite the can 5 to be changed.
  • the empty parking space C is thus in the position in which the storage space B is currently in the representations of FIGS. 1 and 2.
  • the can 33 located on the parking space B projects with its circumferential contour beyond the contour of the can transport vehicle 16.
  • the transport of filled and empty cans according to the arrangement described therefore enables a narrow and space-saving design of the can transport vehicle because they are arranged one behind the other in the direction of travel and do not protrude beyond the profile of the can transport vehicle.
  • Fig. 3 shows a view of the can transport carriage 16 seen from the spinning stations.
  • the can 6 emitting sliver has already been moved to the parking space D in a waiting position.
  • the empty jug 5 is located on the parking space C of the turntable 24.
  • the situation can also be seen from the supervision in FIG. 4.
  • the sliver can 5 of which has run empty, further spinning stations of the spinning machine and the associated cans are indicated.
  • the can transport carriage has a portal-shaped structure.
  • the can changing device 35 is located above the cans arranged on the turntable 24. It consists of a telescopic slide 36 with gripping elements 37 for receiving and holding the cans. The carriage with the gripping elements can be moved transversely to the direction of movement of the can transport carriage 16, as indicated by the double arrow 38.
  • the can transport carriage 16 is requested via the control and monitoring system of the spinning machine, which is not shown in detail here. This communicates with the control system of the can transport vehicle. If a can runs empty at a spinning station, for example, as in the present exemplary embodiment, the can 5 of the spinning station 1, the can transport carriage 16 is requested. At the spinning machine, the requesting spinning station sends out a request signal via a signal transmitter 39, which is received by the receiver 40 on the can transport carriage 16 traveling along the spinning machine. The request and positioning signal is sent to the signal generator 39 via the signal line 39a by a control device of the spinning machine, not shown here.
  • the receiver 40 on the can transport carriage forwards the received signal via the signal line 40a to a control device 41 of the can transport carriage.
  • the control device 41 also controls the drive motor 21 of the flanged rollers 18a and 18b via the signal line 21.
  • the can transport carriage 16 is then stopped when it has positioned itself at the requesting spinning position opposite the can to be changed. To do this, the signal generator 39 and the receiver 40 must face each other exactly. While driving to the requesting spinning station, cans 32 and 33 are arranged one behind the other in positions A and B in the direction of travel.
  • the motor 29 receives a command from the control device 41 via the signal line 29a to rotate the turntable 24 in the direction of the arrow 34, that is to say counterclockwise, by 120 degrees.
  • the empty parking space C is positioned exactly opposite the sliver can 6.
  • the can changing device 35 is now in a position, with its gripping elements 37 after the telescopic slide 36 has been extended, to grip the projecting can 6, which releases fiber sliver, and to first set it down on the empty parking space C on the turntable 24.
  • a telescopically extendable gripper 42 is located below the turntable 24, in the chassis 17. This device is provided in order to temporarily transfer the sliver-dispensing can, here the can 6, to the parking space D.
  • the head of the gripper is a pivotable claw 43 which reaches under the can rim of a can located in position C and shifts the can to position D, as can be seen from position 43 'in FIG. 3.
  • the pivotable claw 43 slides in a slot 44 in the parking space D.
  • a guide rail 45 serves for the lateral positioning of the can to be set down.
  • a fiber sliver guide contour 46 is provided, which in the present exemplary embodiment consists of a vertically downward deflecting rod.
  • FIG. 5 to 7 show in detail the pivotable claw 43 of the telescopic gripper 42 for shifting the cans to the parking space D of the car 16.
  • the gripper 42 has a telescopically extendable and retractable rod 47, as indicated by the double arrow 48 .
  • the extension and retraction can be controlled by the control device 41 via the signal line 42a, for example hydraulically or pneumatically.
  • a rack 50 is drawn in the direction of the arrow 51 via a motor 49, which is controlled by the control device 41 via the signal line 49a.
  • a pivotable claw 43 is pivoted about the axis 53 via a gear mechanism 52 and raised in the direction of the arrow 54.
  • FIG. 7 shows a top view of the swiveling claw 43 which has been erected. If the telescopically extendable rod 47 is moved in the direction of the arrow 57, the gripped can is moved to position D. Once the can change has been carried out, the control device 41 gives the command via the signal line 42a to the telescopic rod 47 to contract and pull the can back onto the turntable. Positioned there, the motor 49 receives the command to retract the rack 50 via the signal line 49a. As a result, the claw 43 is pivoted back into its rest position and its fingers 55 release the edge 56 of the can.
  • a jug can also be transported to parking space D by other means, for example using a drag chain with drivers. It is also conceivable for the carriage of the can changing device to be provided such that it can be moved transversely to its direction of travel when changing the can, that is to say in the longitudinal direction of the can transport carriage.
  • FIG. 8a shows a gripping element 37 of the can changing device 35 for handling the cans in the unactuated state.
  • 8b shows a gripping element in the actuated state.
  • a gripping element 37 is located on the telescopic slide 36 of the can changing device 35 on the right and left on the long sides of the slide.
  • Each gripping element 37 consists of a gripping claw 58 which is pivoted horizontally and lifted vertically by a lever linkage 59. This sequence of movements takes place simultaneously and is triggered by a hydraulically, pneumatically or magnetically acting thrust cylinder 60. The movements of the gripping elements are controlled by the control device 41 via the signal lines 60a. In the unactuated state, the gripping claws 58 are pivoted sideways.
  • the plunger 61 of the thrust cylinder is retracted. It can be extended and retracted in the direction of arrow 62. It is flexible connected to an angle lever 63 which is pivotable about a pivot point 64. This is indicated by the double arrow 65. The swivel path is limited by a limit switch 66, the push cylinder being switched off via the signal line 66a.
  • the gripping claw 58 is articulated to the angle lever 63. Below the attachment point, a rotatably mounted compression spring, for example a gas pressure spring 67, engages. This gas pressure spring keeps the gripping claw open in the non-actuated state.
  • the can transport trolley is positioned on the spinning machine for changing an empty can to a full can and the can changing device 35 has received the command via the control device 41 to extend the telescopic slide 36, this slide 36 moves in the direction of movement 38 towards the front of the spinning machine positions itself with its gripping elements 37 above the jug that is to be changed.
  • the location of the can to be changed is communicated to the control device 41 of the can transport vehicle 16 via the signal transmitter 39 via the receiver 40.
  • the extension of the can changing device 35 is controlled accordingly via the signal line 35a.
  • a precise determination of the can location can either be made by sensors, as not shown here, or else the cans are located on parking spaces that allow the cans to be displaced by stop bars 68 located on the side of the cans and between the cans, along the stop bars 69 running along the spinning machine , do not allow.
  • the sledge then extends to a specified length, which is based on the locations of the cans.
