Definitions

  • the invention relates to a loop taker handling device, a handling unit and a method for handling loop taker modules, in particular cut pile loop taker modules.
  • Loop gripper modules are known in principle from the prior art. For example, that describes EP 1 826 307 A1 a loop taker module comprising a number of flat gripper fingers oriented parallel to one another and held in a base body. Associated with each gripper finger is a slider which is movably supported on the loop taker module to be translationally moved relative to the loop taker module for control of the loop forming process. Each gripper finger is assigned a slider. The slides must be connected to the assembly of the module on the tufting machine with a drive element, so that the slides on the loop taker module can be moved individually or synchronously individually.
  • the DE 29 46 092 A1 describes a two-piece loop taker module. This includes a first base body, which holds mutually parallel gripper fingers, and a second base body, which holds an equal number of parallel to the gripper fingers oriented, this associated bracket. An axial relative movement between the gripper fingers and the brackets is not provided.
  • the package comprises a box having a block disposed therein, which has slots in which the flat parts are frictionally held.
  • the block may be made of wax or gelatin or other material.
  • the tool carrier is formed by a two-legged, thin-walled profile whose free legs are slotted. In the slots, the needles are kept. A lid closes off the rail to preclude losing the needles from the carrier rail.
  • the loop taker handling device is particularly suitable for handling cut pile loop taker modules or other tufting modules which have a number of longitudinally movable slides.
  • the loop taker handling device is a clamping device having a number of clamping receptacles arranged in a row. These clamping receptacles are assigned to the sliders of the loop taker module and can be connected to this.
  • the slides are held in their respective axial positions so that they do not change their axial position relative to the loop taker module during transport and also during insertion into a tufting machine. This makes it particularly easy to couple the entire group of all slides when attaching a tufting module to the tufting machine with the drive device.
  • the clamping device is designed such that the slides are held axially immovable in the individual clamping receptacles by frictional engagement.
  • the frictional force acting in the clamping receptacles between the slides and the corresponding surfaces of the clamping receptacle opposite one another is preferably greater than any occurring during the transport of the loop grippers the sliders acting acceleration force. This ensures that the slides do not change their position during transport.
  • the clamping receptacles are slot-like grooves, both of which facing each other surfaces are flat surfaces or curved surfaces, which are arranged with respect to an imaginary center plane of the slot mirror symmetry to each other and formed.
  • the surfaces of the clamping receptacle are preferably formed without interruption, so that between the respective slider and the voltage applied to it surface of the terminal receiving a large-scale system is formed. As a result, a high static friction and thus a high positional security of the slide is achieved.
  • the surfaces of the clamp receivers do not provide a preferential position of the clamp with respect to an axis of rotation of the clamp directed transversely to the directions of movement of the slides.
  • the clamping device preferably has a number of clamping receptacle whose number coincides with the number of slides a loop gripper module.
  • the clamping receptacles are like the slide preferably arranged at uniform intervals from each other.
  • the clamping device is preferably formed by a bar-like body, in which a series of slots is formed, which form the clamping receptacles.
  • the body is a cuboid, for example.
  • the body is made of a plastic, preferably a plastic, which has an inherent compliance which is at least so great that the clamping forces acting between each slider and its clamp receiver can be overcome by hand.
  • the clamping receptacles preferably have an extension on their open side opposite the bottom, whereby insertion bevels are formed, which facilitates the attachment of a clamping device to the slide of a loop taker module.
  • the seat of the individual slides in the clamping receptacles of the clamping device is preferably fixed so that all slides can be pulled out of the gripper module by a linear movement in the longitudinal direction of the slide with the clamping device.
  • the slides can be kept in the clamping device, for example, for regrinding or cleaning work and also used as a group in the loop taker module.
  • the loop taker module and the clamping device form a handling unit in which all the slides can be moved together axially.
  • the clamping device holds all slides in identical axial position, so that they can not be adjusted against each other even during transport.
  • the clamping is so strong that the axial position of the slide is not adjusted in relation to each other even with shaking movement of the loop taker module.
  • the invention brings particular advantages in the assembly of the loop taker module on a tufting machine.
  • the loop taker module is attached in a pivoting movement to the bar of the tufting machine, wherein all coupling ends of the slider come simultaneously with the corresponding coupling of the drive part of the tufting machine into engagement. After mounting the loop taker the clamping device is removed, so that now the slider, controlled by the drive device, can move freely.
  • FIG. 1 a handling unit 10 is illustrated, to which a loop taker module 11 and a clamping device 12 belong.
  • the loop taker module 11 corresponds to conventional design, as for example from the WO 2006/076558 A1 or the EP 1 826 307 A1 is known.
  • To the loop taker include gripper fingers 13 to 22, which are held in a base body 23 and extending parallel to each other and at uniform lateral distances apart from the base body 23 away.
  • the gripper fingers 13 to 22 are axially fixedly secured in the base body 23.
  • Each gripper finger 13 to 22 is associated with a slider 24 to 36.
  • the slides 24 to 33 are mounted axially movable in the base body 23.
  • the slide 24 to 33 sit in corresponding channels which are formed in the gripper fingers 13 to 22.
  • the sliders 24 to 33 protrude from their guide channels with their respective rear coupling portion 24a.
  • the slides 24 to 33 are straight, flat sheet metal parts, which are held by the clamping device 12 in a predetermined axial position.
  • the clamping device 12 is a preferably one-piece, for example, cuboid body made of plastic or another, somewhat yielding material, as in FIG. 2 is illustrated.
  • clamping receptacles 37 to 43 are formed, which are preferably formed by slot-like, straight, mutually parallel grooves.
  • FIG. 3 illustrates the groove 37 exemplarily for all evenly spaced grooves 37 to 46. The distances between the grooves 37 to 46 correspond to the distances between the sliders 24 to 33.
  • a terminal receptacle 34 representative of the other terminal receptacles 34 to 43 illustrated. It is bounded by one of two preferably flat walls 35, 36 Slit formed. The two walls 35, 36 are arranged symmetrically to a center plane 37. If the wall surfaces 35, 36 are formed curved, they are also arranged symmetrically to the center plane 37.
  • FIG. 4 illustrates a modified terminal receiving 34, in which the wall surfaces 35, 36 at its furthest from the slot arc 38 place inclined surfaces 39, 40 which form a wedge-like extension of the terminal receiving 34 and serve as insertion bevels for each associated slide.
  • the lying between the individual clamping receptacles 34 to 43 wall portions of the preferably formed as a solid part body of the clamping device 12 may have a certain low compliance, so that each slide 24 to 33 clamped, i. held frictionally held in the respective terminal receiving 34 to 43.
  • the excess of the slider with respect to the terminal receiving is preferably such that hand forces for applying the clamping device 12 to the slide 24 to 33 and for removing the clamping device 12 are sufficient.
  • FIG. 5 The loading of the tufting machine takes place as in FIG. 5 indicated.
  • a bar 41 which is equipped with a series of loop gripper modules 11 and performs a swinging motion to grasp and hold loops and possibly cut open.
  • the barre are associated with one or more drives 42, which carry a coupling structure 43 at their respective module-side end. This is adapted to engage with the coupling end 24a of the respective slider 24 in positive engagement.
  • the coupling structure 43 and the coupling end 24a are formed complementary to each other and fit into one another in a form-fitting manner. You can through a clutch movement in and disengaged.
  • the coupling movement typically differs from the longitudinal movement of the sliders 24-33.
  • the handling unit 10 For mounting the loop taker module 11, the handling unit 10, such as FIG. 5 illustrated, brought to the bar 41, wherein a positioning projection 44 must engage in a corresponding recess 45 of the bar 41.
  • the attachment of the handling unit 10 to the bar 41 is carried out as in FIG. 5 indicated by arrows 46, 47, 48, in a slight pivotal movement, wherein the positioning projection 44 or any other positioning structure in the associated recess 45 and the coupling end 24a in the coupling structure 43 find.
  • the clamping device 12 After attachment of the loop taker module 11 to the bar 41, the clamping device 12 can be removed. The machine is thus able to work.
  • the loop taker modules 11 can be removed from the bar 41. Before loosening the loop taker modules 11 from the bar 41, a clamping device 12 is first attached to all slides 24 to 33 of each loop taker module 11. Thereafter, the loop taker module 11 is released from the bar 41 and removed.
  • the slides 24 to 33 can not move axially relative to each other now. But they can be considered as a whole, i. all at once pulled out of the base body 23 and supplied for example, a cleaning or other processing.
  • the handling unit 10 comprises a loop taker module 11 and a clamping device 12, which is in frictional connection with the slides 24-33 of the loop taker module 11, but preferably not with the hook finders 13-22.
  • the slides 24 - 33 are in corresponding slots of the Clamping device slightly clamped and can not slip against each other even with shaking movement and in particular not slip out of the loop taker module 11.
  • the slides 24 - 33 are thus all in the same axial position and must not be moved by hand during assembly.
  • the clamping device 12 formed, for example, as a plastic clip, it only has to be pressed to the loop taker module 11 or pulled away from the loop taker module 11, both if necessary connected to a rotational movement about an axis of rotation directed transversely to the direction of movement of the slides 24-33.
  • the plastic clip can be levered in a rotating movement of the sliders 24 - 33.
