Definitions

  • the present invention concerns a transport device for a drawing-in machine.
  • the present invention also concerns a drawing-in machine for drawing-in warp threads into harness components of a loom, said drawing-in machine including, amongst others, a transport device.
  • the present invention concerns a method for transporting harness components in a drawing-in machine.
  • the present invention belongs to the technical field of drawing-in warp threads into harness components of a loom.
  • a harness component is a part of a loom configured to be crossed by a warp thread when it is used on a loom.
  • a harness component can be a heddle or a dropwire.
  • WO92/05303A1 discloses a transport device with holding elements arranged next to one another and moved by a chain. Each holding element is capable of transporting a heddle from a transfer position into a discharge position via a threading position. Movements of the single carrying chain are regular and they cannot be adapted to different yarns without penalizing the movement of the other holding elements. Because of the close arrangement of the holding elements in the discharge zone, entanglement of yarns can occur.
  • a transport device comprises a first holding element and a second holding element configured to be moved cyclically and rotatably between a feeding device and a receiving device.
  • the first holding element can move, on a portion of its path, between the feeding device and the receiving device, while the second holding element stays stationary.
  • Two motorized carrying members are provided and each of them carries a single holding element, which must run over a complete closed transport path to get another harness component when necessary. This requires high-speed movements and can make the harness components unstable, in particular when one holding member stops at a threading position or at a discharge position, where stability is essential.
  • the movement of the holding elements is a rotation and the closed path of the holding elements is circular, which is not adapted to straight parallel feeding magazines and straight parallel receiving devices.
  • FR2930950A1 discloses a transport device with several holding elements movable between a transfer position, next to a feeding device, and a discharge position, next to a receiving device. Some holding elements are driven on a first portion of the transport device by a constant pitch motor, from the transfer position to a threading position, while at least one of the holding elements is driven on a second portion of the transport device by a non-constant pitch motor between this threading position and a discharge position.
  • This layout needs two types of motors, namely a constant pitch motor and a non-constant pitch motor, and two kinematic chains to generate independent movements of the holding elements.
  • WO00/11252A1 discloses a single rotating carousel with several holding elements combined with a discharging belt.
  • the carousel transports some harness components on a first portion of the transport device from a transfer position to a threading position.
  • a discharging belt transports the harness components on a second portion of the transport device between the threading position and one of the discharge positions.
  • Different technologies are needed to transport harness components on their whole path.
  • a switch of harness components must be operated from the carousel to the discharging belt.
  • Each holding element carries pistons able to hold a harness component and moved for loading/unloading a harness component when the holding element is at the transfer position or at the switch position, while the pistons are stationary and firmly hold the harness component when the holding element moves between the transfer and the switch positions.
  • the switch of the harness components between the first and second portions of the transport device reduces the operational speed of the transport device and may cause some jamming of the harness components.
  • the purpose of the present invention is to avoid the drawbacks of the prior art with a new transport device capable of moving each harness component with a differentiated speed profile and without any switch between different portions of the transport device.
  • the invention concerns a transport device for a drawing-in machine, said transport device being configured to move harness components relative to a frame of the transport device, between at least one transport transfer position and several discharge positions, via at least one threading position, where a thread is inserted into a transported harness component, the harness components being exclusively heddles or exclusively dropwires.
  • the transport device includes several transport conveyors, each transport conveyor including at least one carrying member and at least a drive for moving the carrying member relative to the frame separately from any other transport conveyor.
  • a controller is connected to the drives of the several transport conveyors.
  • Each carrying member is configured to transport at least a harness component, which is different from the harness components transported by the other transport conveyors, from the at least one transport transfer position, where a harness component can be loaded onto the carrying member, to one of the several discharge positions, where a harness component can be transferred from the transport conveyor onto a receiving module of the drawing-in machine, via the at least one threading position.
  • several harness component-holding elements are secured to each carrying member, each harness component-holding element is configured to hold a harness component and to move along a closed transport path common to all transport conveyors and going through each transport transfer position, through each threading position and through each discharge position. I harness component-holding elements of the several transport conveyors are adjacent to each other along the closed transport path.
  • the several transport conveyors of the transport device can be used in parallel to carry one or several harness components from the transport transfer position, to the threading position and to the discharge positions.
  • the several harness component-holding elements secured to each carrying member of the transport conveyors efficiently hold the harness components during their displacement between the above-mentioned positions.
  • Speed profile of movement of each transport conveyors can be optimized with the discharge positions of each harness component, with the warp thread to drawn in the harness component, with the type of harness component, etc. With optimized speed profiles, harness components remain stable, during transport by the transport device and when they reach the threading and discharge positions.
  • the different conveyors make it possible to optimize the movements according to the time taken by each operation, e.g. feeding, threading and discharging the harness components. These different conveyors also make it possible to carry out certain movements in masked time.
  • a harness component can be a heddle or a dropwire and, more generally, any element which needs to be equipped with a warp thread prior to being integrated into the harness of a loom.
  • the invention concerns a drawing-in machine for drawing-in warp threads in harness components for a loom.
  • This drawing-in machine comprises a transport device as mentioned here above, a harness components-feeding device where the harness components are provided in the form of at least one stack and a harness component-separating device configured to separate one harness component from the at least one stack.

  • the duplex heddles can be of two types, namely left heddles 60L or right heddles 60R.
  • a heddle is an example of a harness component usable on a loom.
  • the drawing-in machine 2 also includes a heddles-separating device 8, a heddles-sorting device 10, a heddles-transport device 12, a heddles-detection device 14, a controller 16, a thread-insertion device 18, a heddles-receiving module 20, a dropwire module 22, a warp-clamping frame 24 for clamping warp yarns of a non-represented warp beam, a heddles-transfer device 26 and a heddles-discharging device 28.

  • the reference axis Y is a longitudinal axis of the heddles-feeding device 4 and, within the stack 6, the heddles 60 are adjacent to each other along the longitudinal axis Y.
  • A60 denotes a longitudinal axis of a heddle 60. This axis A60 extends between the end loops 62 of each heddle 60 and is parallel to their longest dimension. This longitudinal axis A60 is parallel to the reference axis Z when the corresponding heddle is mounted on the heddles-feeding device 4, on the heddles-sorting device 10 and on the heddles-transport device 12.
  • the heddle stack 6 can be directly extracted from a heddle frame that has been previously used on a loom.
  • a stack 6 includes right and left heddles 60L, 60R but their alternation might be altered by heddles added on the frame during its previous period of use on a loom. Thanks to the heddles-sorting device the distribution of heddles 60 in the stack 6 does not have to be precisely known nor controlled in advance
