Definitions

  • the present invention relates to a warp-processing textile machine with a first warp beam receiver and a second warp beam receiver, which differs from the first warp beam receiver.
  • the invention relates to a method for operating a warp-processing textile machine with a first warp beam receiver and a second warp beam receiver.
  • a warp beam placed in a warp beam receiver is unwound.
  • the warp beam must be changed.
  • the empty warp beam must be removed from the textile machine, which can only be accomplished by lifting devices in conjunction with a lifting harness due to the dimensions and weight of the warp beam.
  • the lifting harness is applied to the empty warp beam, as a result of which the warp beam can be removed using the lifting device, for example a crane.
  • the empty warp beam is put aside and the lifting harness is removed.
  • the lifting harness can be applied to a new, full warp beam, whereby the new warp beam can be inserted into the textile machine using the lifting device.
  • the process can be accelerated by using several lifting devices and lifting gear. However, many handles and lifting operations are required. This is time-consuming and labor-intensive.
  • DE 10 2012 205 890 B4 describes a warp beam changing arrangement in which three warp beams are arranged in a turning device. In this case, a warp beam is unwound while a second warp beam is in a waiting position, and a third warp beam can be exchanged. By rotating around the axis the rotating device transfers the second warp beam to the position of the first warp beam, so that the empty warp beam can be replaced by a full warp beam.
  • GB 111 12 21 A describes a warp beam receiving device with two warp beam receptacles, in which two warp beams are arranged next to one another in an axial direction.
  • One of the two warp beam holders is height-adjustable. Loaded warp beams are placed on the warp beam receiving device by a forklift truck or the like. With the height-adjustable warp beam mount, the axes of the warp beams are aligned in such a way that a mandrel can be pushed through both warp beams. As a result, the warp beams are connected to one another and can be laid as a composite in a further processing machine, for example a warp knitting machine.
  • U.S. 3,219,206 A describes an automatic textile support transfer device.
  • the device has an inclined surface on which empty carriers can be stored. Textile carriers are held by holding devices on one side and a stop device is provided on the other side.
  • U.S. 4,629,143 A describes an arrangement in which support elements are placed in a gate assembly to reduce loading and unloading times.
  • the carrier elements are arranged on different levels, with the carrier elements being formed by rails.
  • U.S. 1,655,226 A describes a roll holder for two or more rolls. One of the reels is held in an active position while the other reels are placed in an inactive or standby position.
  • the object on which the invention is based is to achieve high productivity.
  • the first warp beam receiver and the second warp beam receiver are connected to one another by a guideway, with a start of the guideway on the second warp beam receiver being arranged higher in the direction of gravity than an end of the guideway on the first warp beam receiver.
  • a first warp beam can be arranged in the first warp beam receiver and a second warp beam can be arranged in the second warp beam receiver and prepared there.
  • the warp beam receptacles are connected to one another by the guideway, with the beginning of the guideway being higher in the direction of gravity than the end.
  • the second warp beam receptacle preferably has a detachable holder.
  • the detachable holder prevents the warp beam from moving unintentionally out of the second warp beam receptacle, thereby preventing a collision with a warp beam located in the first warp beam receptacle. If the first warp beam receptacle is free, the detachable holder can be released or moved in order to release the warp beam. The warp beam can be transferred to the first warp beam receiver. This holder enables the warp beam to be moved in a targeted manner and increases safety.
  • the first warp beam receptacle preferably has a catching device.
  • a catching device stops the movement of the warp beam, which can be transferred from the second warp beam receiver into the first warp beam receiver.
  • the warp beam can thus assume a defined position in which the now inserted warp beam can be unwound.
  • the catching device can also have a braking arrangement that can gently brake the movement of the warp beam, such as a spring and/or damper arrangement or the like.
  • the catching device is preferably designed as part of a bearing shell receptacle.
  • the catching device can fulfill a dual purpose in that it also acts as a bearing shell mount. Multiple use saves costs, both in production and in assembly.
  • the bearing shell mount is preferably designed in multiple parts and part of the bearing shell mount is movable. As a result, part of the bearing shell be moved so that an open bearing shell is created from which the warp beam can be removed or inserted into it. This arrangement makes it easy to change the warp beam.
  • a warp beam is arranged in the second warp beam arrangement, which beam has a first roll diameter and a second roll diameter, the second roll diameter differing from the first roll diameter, the guideway has a first section and a second section, the second section differing from the first section, and that the first roll diameter cooperates with the first section and the second roll diameter cooperates with the second section.
  • the first roll diameter can have a warp beam support tube and the second roll diameter can have a bearing arrangement of the warp beam.
  • the first rolling diameter, starting from the second warp beam arrangement first interacts with the first section of the guideway. If the warp beam moves in a rolling motion starting from the second warp beam receiver, this motion can be described by a certain angular velocity.
  • a translatory movement of the warp beam results from the angular velocity with a diameter. With the same angular velocity, a larger diameter achieves a greater translational movement than a smaller diameter. If the warp beam moves with its first roll diameter (large roll diameter) in the first section, the translational speed is greater than if the warp beam moves with its second roll diameter (small roll diameter) with the same angular velocity in the second section. In this way, the translatory movement is reduced and/or slowed down. As a result, the force to be absorbed is smaller, which means that the safety gear can be made smaller.
  • the second roll diameter of the warp beam is preferably arranged in an unwinding position in the catching device.
  • the warp beam is securely stored and can be unwound directly from the first warp beam pickup. There is no further movement of the warp beam, which increases productivity.
  • the object is achieved in a method of the type mentioned in that a warp beam is transferred from the second warp beam receiver, driven by gravity, along a guide track into the first warp beam receiver.
  • the warp beam is driven by gravity and transferred from the second warp beam receiver along the guideway to the first warp beam receiver.
  • additional peripherals such as a drive, a transmission, or the like, can be omitted, which keeps costs down.
  • downtime of the textile machine is reduced since the warp beam can be changed quickly by a single operator, which means that productivity can be increased.
  • a detachable holder preferably fixes the warp beam in the second warp beam receptacle.
  • the holder prevents the warp beam from moving unintentionally in the second warp beam receiver, which increases operational safety.
  • the holder can be arranged in different positions, such as a holding position or a release position.
  • the warp beam is preferably released by moving the holder.
  • the warp beam can be released by transferring the holder from the holding position to the release position.
  • the warp beam can be transferred to the first warp beam receptacle as soon as it is free. So you can insert another warp beam in reserve in the second warp beam receptacle.
  • the guide track has two sections, with the warp beam being braked in its movement in a second section. Braking in the second section reduces the speed of the warp beam, so that the forces to be absorbed by a safety gear can be reduced.
  • a translatory movement of the warp beam is slowed down by changing a support from a first roll diameter of the warp beam in the first section to a second roll diameter of the warp beam in the second section. If the warp beam reaches a certain angular speed during its movement, its peripheral speed can be determined from this angular speed in combination with the diameter on which the warp beam rolls. A speed of the translational movement can also be determined from the circumferential speed. If the diameter is reduced at the same angular speed, the peripheral speed and thus the speed of the translatory movement of the warp beam are also reduced. The warp beam is braked accordingly. Such an arrangement makes it possible to dispense with further braking devices.
  • a catching device preferably encloses the second roll diameter in an unwinding position. This arrangement eliminates the need for a further warp beam receiving device.
  • the first warp beam receiver can be arranged in the same position as previous warp beam receivers in textile machines. Therefore, there is no need to change over the textile machine, in particular a warp knitting machine.
  • the first warp beam mount 1 has a catching device 4, which can be designed as a bearing shell mount.
  • the second warp beam receiver 2 also has a detachable holder 5 which can be arranged in a first position (holding position) or a second position (release position) which differs from the first position.
  • the guide track 3 has a first section 6 and a second section 7 .
  • the first section 6 is arranged in the area of the second warp beam receiver 2 and the second section 7 in the area of the first warp beam receiver 1, with the two sections 6.7 overlapping at least partially.
  • a warp beam 8 has two different roll diameters 9 , 10 , a first roll diameter 9 and a second roll diameter 10 .
  • the first roll diameter 9 interacts with the first section 6 of the guideway 3 and the second roll diameter 10 with the second section 7 of the guideway 3 .
  • the first roll diameter 9 is larger than the second roll diameter 10.
  • a start of the guide track 3 is arranged in the area of the second warp beam receptacle 2 . This area is higher than one end of the guide track 3 in the direction of gravity.
  • the guide track 3 can be designed as a rail, profile, shaped element or the like. Furthermore, in addition to a linear embodiment, the guide track 3 can have other embodiments, such as a parabola or the like. However, the course of the guide track 3 should be aligned so that the warp beam 8 proceeds through a release can be transferred from the second warp beam receptacle 2 to the first warp beam receptacle 1, driven by gravity.
  • the holder 5 holds the warp beam 8 in a waiting position.
  • the warp beam 8 can be released by moving the holder 5 from a first position, a holding position, into a second position, a release position. As a result, the warp beam 8 can move along the guide track 3 and be transferred from the second warp beam arrangement 2 to the first warp beam arrangement 1 .
  • the warp beam 8 moves, driven by gravity, in the direction of the first warp beam receiver 1.
  • the warp beam 8 is first in the first section 6, with which the first roll diameter 9 interacts.
  • the warp beam 8 rolls along the guide track 3 and reaches a certain angular velocity (T out ), from which a translatory movement (arrow) of the warp beam 8 can be determined in connection with the roll diameter 9 .
  • the first section 6 and the second section 7 overlap in a certain area. Starting from this area, the second rolling diameter 10 and the second section 7 interact. Since the second roll diameter 10 is smaller than the first roll diameter 9 in this exemplary embodiment, the movement of the warp beam changes. Because, as already described above, the translational movement depends on the angular velocity and the rolling diameter.
  • the catching device 4 can therefore intercept a smaller force of the warp beam 8 being moved.
  • the warp beam 8 is positioned by the catching device 4 in such a way that it can be unwound in this position, an unwinding position. This will the warp beam 8 is arranged in bearing shells of the safety device 4 .
  • the bearing shells can be designed to be divided so that the warp beam 8 can be easily inserted and removed.
  • the second roll diameter 10 is arranged at least temporarily for processing the warp beam 8 .
  • a change of the warp beam 8 of the first warp beam receiver 1 is described below.
  • a first, empty warp beam 8 is unwound in the first warp beam receiver 1 and a second, full warp beam 8 is wound in the second warp beam receiver 2 ready.
  • the catching device 4 or the bearing shells are brought into a removal position so that the unwound warp beam 8 can be removed from the first warp beam receiver 1 .
  • the second warp beam 8 can be transferred from the second warp beam receiver 2 into the first warp beam receiver 1 .
  • the holder 5 is transferred from the holding position to the release position, as a result of which the second warp beam 8 is released in the second warp beam receptacle 2 .
  • the second warp beam 8 moves along the guide track 3, driven by gravity, in the direction of the first warp beam receiver 1. The movement can take place by rolling, sliding or a combination of rolling and sliding.
  • the first roll diameter 9 is in contact with the first section 6 in the process.
  • the contact of the first roll diameter 9 separates from the first section 6, and contact between the second roll diameter 10 and the second section 7 of the guideway 3 is formed.
  • the second roll diameter 10 of the warp beam 8 interacts with the second section 7 .
  • a rolling movement is accompanied by a certain angular velocity.
  • the angular velocity results in a translatory movement velocity. If the roll diameter 9,10 changes from the first roll diameter 9 to the second roll diameter 10 while the angular velocity of the warp beam 8 remains the same, the translatory movement speed of the warp beam 8 changes Translational movement of the warp beam 8 is braked.
  • the catching device 4 finally catches the warp beam 8 completely and transfers the warp beam 8 to an unwinding position in which the warp beam 8 can be unwound.
  • the second roll diameter 10 is arranged in the catch device 4 or the bearing shells.
  • a new warp beam 8 can be placed in the second warp beam receiver 2 .
  • the holder 5 is brought into the holding position. The process can start again from .
  • the warp beam arrangement described can be used, for example, on a warp knitting machine. Alternatively, the warp beam arrangement described can also be used on other textile machines working with warp beams 8 or on machines that equip a warp.
  • An empty warp beam 8 can lie in the second warp beam receptacle 2 while a warp beam 8 is being wound by the warp beam winding machine. After the warp beam 8 has been wound, the empty warp beam 8 can be transferred to the first warp beam receptacle 1, as described above.
