Definitions

  • the invention relates to an assembly of an OE spinning machine with a spinning device for the sliver provided and a mobile can changing device cooperating with the OE spinning machine, which has a device for automatically replacing empty with filled sliver cans, parts of this device on the one hand on the OE spinning machine and on the other hand are arranged on the can changing device, with a device arranged on the mobile can changing device for detecting the lack of sliver at a spinning station and triggering a can changing request signal and a control device.
  • This reference discloses a can changing device which can be moved along an OE spinning machine and which receives filled sliver cans at a loading station arranged on the spinning machine end and exchanges them at the spinning stations for empty sliver cans.
  • sliver cans are arranged on rotary tables, which are combined to form spinning station groups.
  • Empty cans are rotated by the can changing device into an exchange position, taken from their turntable position and replaced with full sliver cans.
  • the can changing device has a sliver button for recognizing empty spinning cans or missing sliver and manipulators for picking up empty and inserting full spinning cans.
  • a device for inserting the sliver end arranged on the full sliver cans into the sliver compactor of the opening roller housing is arranged on this known can changing device.
  • a disadvantage of this known device is, inter alia, that empty sliver cans are generally only recognized when the remaining sliver piece has already been drawn into the spinning box. Since this piece of fiber sliver often differs from the normal sliver in terms of its fiber mass, the spinning box produces defective yarn in this case, which must then be removed from the package.
  • the invention has for its object to make the automatic replacement of the sliver cans more effective.
  • the transmitter for a can change request signal which cooperates with a belt monitoring device, acts on the receiver of the mobile can change device in order to cause it to carry out the can change as effectively as possible, that is to say quickly and safely, at the requesting spinning station. This also includes creating the prerequisites for the spinning station to be able to go back into operation immediately after changing the can.
  • the can changing device which is parked in front of the spinning station on request, opens and closes the guide eyelet according to the program, inserts the fiber sliver into the guide eyelet and connects the two fiber sliver ends to one another. She carries out these activities in addition to her main activity, changing the cans.
  • the can changing device advantageously carries at least one filled can with it. It advantageously takes the replaced empty jug back with you. As soon as they no longer have filled cans available, they can drive to an unloading point for empty cans and a loading point for filled cans, for example to receive several filled cans there.
  • FIG. 1 shows a spinning station 2 of an OE automatic spinning machine 1.
  • a mobile can changing device 3 is parked in front of the spinning station 2.
  • the spinning station 2 processes the fiber sliver 7 drawn upward from the can 4 and entering the sliver entry point 5 of a dissolving unit 6 into a thread 8 which is wound on a cheese 9.
  • the resolving unit 6 is located together with a rotor 10 in a spin box 11.
  • the fibers of the fiber sliver 7 which are dissolved by the opening unit 6 pass through a fiber channel 15 into the rotor 10, where they form a fiber ring from which the thread 8 is finally formed.
  • the thread 8 is continuously drawn out of the draw-off tube 14 by a draw-off roller 16 in cooperation with a pivotably mounted contact roller 17, guided over a thread guide wire 18 and through a reciprocating thread guide 19 and from there out of the cross-wound bobbin rotating in the direction of arrow 20 9 fed.
  • the cheese 9 is driven by a drive roller 22 rotating in the direction of the arrow 21 by friction.
  • the cheese 9 is mounted in a pivotable bobbin frame 23 on the machine frame 24 of the spinning station 2 in such a way that it always bears against the drive roller 22 from above.
  • the opening unit 6 can be driven on its shaft 12, the rotor 10 on its shaft 13, for example by tangential belts 47, 48.
  • the sliver 7 runs at a distance from the sliver entry point 5 through a guide eyelet 25, which is shown in FIGS. 4 and 5 in natural size.
  • the guide eyelet 25 is formed by the combination of a fixed guide piece 26 with a movable guide piece 27.
  • a groove 28 guiding the sliver 7 is incorporated into the fixed guide piece 26, into which the movable guide piece 27 is located the influence of gravity, because it is arranged at the lower end of a pivoted lever 29.
  • the fixed guide piece 26 sits at the lower end of a tab 31 which is connected to the machine frame of the OE spinning machine 1 and which carries a bracket 33 above the guide piece 26, which has a pivot joint 35 for the lever 29.
  • the lever 29 is provided with a handle 37 which serves to pivot the lever 29 back and thus to pull back the guide piece 27, as a result of which the guide eyelet 25 is opened from the side for inserting the sliver 7.
  • the spinning station 2 is also provided with a belt monitoring device 39, which is designed as a sliver monitor.
  • the sliver monitor 39 has an electrical operative connection 42 to a shutdown device 43 of the spinning station 2, so that the spinning station can be stopped as quickly as possible in the absence of a sliver presence signal.
  • the shut-off device 43 which is designed as an electromagnetic drive, advances a switching rod 45 in the direction of arrow 44, which is articulated to the spinning box 11.
  • the spin box 11 pivots forward about a swivel 46 so that the shafts 12 and 13 lose their contact with the tangential belts 47 and 48 driving them.
  • the sliver monitoring device 39 which is designed as a sliver monitor, has a sliver thickness measuring device 49 which is arranged in the fixed guide piece 26 and which is shown in particular in FIG. 5. It is designed as an optoelectrical measuring device, the beam path 50 of which extends transversely through the sliver 7 leading groove 28.
  • a light transmitter 55 is supplied with electrical energy from the band monitoring device 39 via electrical lines 51, 52.
  • a lens 56 parallelizes the light beams emitted by the light transmitter 55. The parallel Rays of light are deflected 90 degrees by a first mirror 58 and directed across a groove 28 through a first window 60.
  • the light rays pass through a second window 61 and are then deflected again by 90 degrees by a second mirror 59, so that they meet a second lens 57 designed as a converging lens, in the focal point of which there is a light receiver 62 which receives the luminous flux received corresponding electrical current via electrical lines 53, 54 to the tape monitoring device 39.
  • the beam path 50 is shaded, so that the band monitoring device 39 receives a smaller electrical current than when the groove 28 is empty.
  • the shutdown signal going to the shutdown device 43 takes place via the electrical active connection 42. This is the case, for example, when a sliver can runs empty and the sliver end 63 (FIG. 4) leaves the groove 28. Since the spinning station 2 or its sliver feed is switched off very quickly, the sliver end 63 hanging out of the sliver entry point 5 remains in the position shown in FIG. 4.
  • Fig. 1 shows that the can changing device 3 parked just in front of the spinning station 2 has a chassis 64 which is provided with two grooved castors 65 and two smooth casters 66.
  • the castors rest on rails 67, 68, which are attached to floor 69 parallel to the OE spinning machine.
  • a controllable undercarriage motor 70 drives one of the driving rollers 66.
  • Filled or empty cans can be transported on a platform 71 of the can changing device 3. 1 shows that an empty jug 72 is currently on the platform 71 located. The can 72 was previously removed from the spinning station 2 and replaced with the filled can 4 transported by the can changing device 3
  • the can changing device 3 has a manipulator 74 which can be moved on rollers 75, 75 'in a horizontal rail 76 transversely to the direction of travel of the can changing device 3 in the direction of the spinning station 2 and away from the spinning station 2. It can be moved back and forth along the rail 76 by a belt drive 80.
  • the rail 76 carries brackets 90 and 91.
  • the bracket 90 carries two rollers 77 and the console 91 two rollers 77 '.
  • the rollers 77 are in a rail 78.
  • the rails 78 and 78 ' are arranged on the can changing device 3 in the direction of travel, so that the manipulator 74 can also be moved along the rails 78 and 78' for a limited distance in the direction of travel.
  • An adjusting spindle 79 is used for this purpose, which is rotatably mounted on the machine frame of the can changing device 3 and engages in a spindle nut 73 connected to the bracket 91.
  • the manipulator 14 is used to bring can grippers 81 connected to it over a can to be transported.
  • Fig. 1 shows that the can grippers 81 of the manipulator 14 grip just under the bead 88 of the can 72.
  • the can grippers 81 can be pivoted against the can and away from the can and can also be lifted up.
  • the can grippers 81 have a special, controllable drive device 92.
  • the manipulator 74 of the can changing device 3 is also provided with a device designated overall by 93, which serves to connect the sliver 7 inserted in the guide eyelet 25 of the new can 4 to the end 63 of the old sliver protruding from the sliver entry point (FIG. 4).

If the crank 98, at the end of which the combination 94, 95 is attached, is pivoted out of the tape take-up position A by 90 degrees from this position , the combination reaches an intermediate position labeled B, also called the transport position. If the can changing device 3 is to be moved further on the rails 67 and 68, the combination 94, 95 must be in the intermediate position or transport position B in order not to knock against machine parts of the OE spinning machine.
  • crank 98 is pivoted out of intermediate position B by a further 90 degrees in the direction of arrow 89 and at the same time advanced in the direction of arrow 97, that is to say in the axial direction of crank 98, splicer 95 reaches the splice position in which band gripper 94 stands vertically above the splicer 95.

  • the feed of the crank 98 in and against the direction of the arrow 97 is ensured by a telescopic arrangement 85 which can be acted upon pneumatically, for example.
  • the manipulator 74 As soon as the manipulator 74 is pushed out of the position shown in FIG. 1 to the left, for example in order to transfer a can to the spinning station 2, it pushes a linkage 86 forward, which as a device for opening and closing the guide eyelet 25 a control rod 87 owns.
  • the control rod 87 takes the handle 37 of the lever 29 with it, so that the lever 29 pivots counterclockwise and thereby pulls the movable guide piece 27 out of the groove 28, whereby the guide eye 25 is opened.
  • the beginning of the sliver hangs down over the bead 88 'of the jug, as is indicated by dash-dotted lines in Fig. 1 on the jug 4.

  • the control rod 87 releases the handle 37 of the lever 29 again, so that the guide piece 27 engages again in the groove 28 of the guide eyelet 25 and the guide eyelet 25 thereby closes. It is now capable of guiding the sliver 7 properly, with the sliver thickness measuring device 49 continuously monitoring the sliver 7.
  • Fig. 1 shows that the spinning station 2 is equipped with a transmitter 111, which cooperates with the belt monitoring device 25 and is intended to output a can change request signal.
  • the transmitter 111 is designed as an optoelectric transmitter. It is connected to the belt monitoring device 39 (FIG. 5) by an active connection 112. As soon as the belt monitoring device 39 responds, that is to say as soon as the sliver is no longer present in the guide eyelet 25, the transmitter 111 emits a light beam which is received by a receiver 113 provided on the chassis 64 of the can changing device 3 and identified as a request signal.
  • the receiver 113 is designed as an optoelectric receiver. It has active electrical connections 114 and 115 to the program control device 99. After receiving a can change request signal, the program control device 99 first causes the can changing device 3 to be positioned and then parked in front of the requesting spinning station 2.
  • Fig. 6 shows an alternative embodiment of a strip thickness measuring device 49 '. It has an electrical plate capacitor, the capacitor plates 116, 117 to both Sides of the sliver leading groove 28 'are arranged opposite one another.
  • the capacitance of the electrical capacitor formed from the capacitor plates 116 and 117 differs depending on whether there is only air or additionally fiber sliver between the two plates. The presence or absence of the fiber sliver is inferred from the change in capacitance, which can be determined, for example, in a sensitive electrical measuring bridge.
  • Such a capacitive measuring device takes the place of the optoelectric monitoring device 49 in the belt monitoring device 39.

This happens as soon as the switching extension 125 switches on the microswitch 40, which is always the case when the roller 120, which engages in a groove 128 machined in the roller 119, no longer finds sliver 7 there, but instead scans to the bottom of the groove.
  • a belt monitoring device 41 can be arranged in the form of a counter Z, which responds to the revolutions of the roll 129 and relates the number of revolutions to the sliver length that has passed. It can be an electrical counter 41, for example, which generates a pulse each time a switching extension 129 present on the roller 119 passes and adds the pulses.
  • the transmitter 111 can have a second active connection 130 to the counter 41, which is activated as soon as the counter has counted the predetermined number of pulses.
  • the transmitter 111 then sends out a first request signal, which the program control device 99 of the can changing device 3 identifies as a first request signal, with the result that it first positions and parks the optional changing device 3 by switching the undercarriage motor 70 accordingly in front of the requesting spinning station 2. It then waits for a second request signal on the part of the transmitter 111, which is emitted, for example, by the microswitch 40 at the moment in which the sliver end 63 is just leaving the pair of rolls 119, 120.
  • the can change can now begin practically at the same time as the spinning station 2 is switched off by the switch-off device 43. You do not have to wait until the can changing device 3 passes the requesting spinning station 2 because it is already ready.
