Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] According to a first aspect, the invention relates to an apparatus and a method for accommodating and holding a wedge element in a warp retractor, in particular a sheet for a loom. According to a second aspect, the invention relates to an apparatus and a method for distributing these wedge elements to a support member provided for placement in a loom.

[0002] Such sheets are usually stored in magazine form and inserted into a sheet separating device for a warp pull-in machine, as is evident, for example, from Swiss Patent No. 687027. The bending or bulging of the lamellas (see FIG. 3 here) is characteristic of such a separation, whereby the front lamella is
It is moved away from the second sheet so that it can be easily grasped in the central area. It is also known to set the height of the thread eye of such a sheet by turning a contact rail slit, which contact rail slit is provided in the region of the upper end of such a wedge element. This contact rail slit is used for supporting or suspending the wedge element or sheet.

[0003] Apparatus and methods according to the analogy—for distributing the sheets used in looms—
For example, it is known from Swiss patent 682577. These devices accommodate the lamellae in a separation position and-in a first step-
Mounted on a so-called "merry-go-round" or sheet distribution module (see here FIGS. 3 or 7), which holds the sheet and feeds it to the retracted position, where the thread is drawn through the sheet eye. . This is effected by means of a retracting device, for example, as described in Swiss patent 679598. In a second step, the lamellas-together with the retracted thread-are fed to a dispensing position and are arranged here on one or more support members, for example contact rails.

[0004] While the use of merry-go-rounds has its advantages,-if the number of interfaces and sources of error between the individual parts of the warp puller can be reduced- Especially the so-called “jump report”
In other words, it is erroneous if the lamination is carried out in such a way that the lamellas with the drawn-in thread are distributed in any order to a plurality of normally arranged side-by-side feed members or to contact rails. There is a danger of retraction. In this case, the jump report means that the distribution of the sheets is in the order 1, 4, 2, 5, 3, 6, or 3, 4, in the contact rails having, for example, six consecutive numbers and arranged side by side.
2, 5, 1, 6.

It is an object of the present invention to propose an apparatus or a method which can accommodate and hold a wedge element, such as a sheet, and which can execute a jump report when dispensing the sheet. is there.

[0006] According to a first aspect, this is achieved as follows by the features of claim 1. In other words, a device is proposed for receiving and holding a wedge element between two opposing holding surfaces, in particular a sheet for a loom, which is movable and has a first holding device in a first cylinder. It is characterized by a first piston having a surface and a second piston movable in a second cylinder and having a second holding surface. Advantageous variants are evident from the dependent claims 2 to 13.

[0007] According to a second aspect, the object is met by claim 14 as follows. In other words, a method has been proposed for accommodating, holding and distributing the wedge element, in particular for the looms, for a loom, which comprises the following work steps: Storing of the lamella in the separating position; Aligning the lamella; feeding the lamella into the retracted position; holding the lamella during the retraction of the thread; and feeding the lamella into the transfer position; and the method comprises receiving and holding the lamella and It is characterized by the use of a device according to one or more of claims 1 to 8 for sending. Advantageous modifications are evident from the dependent claims 15 to 17.

[0008] The arrangement of the apparatus and method will now be described graphically, in the form of schematic representations of examples and without limiting the scope of the invention in any way.

FIG. 1 shows a warp pull-in machine. It consists of a base frame 1 and various constituent groups arranged therein, each of these constituent groups being 1
Form one functional module. In front of the base frame 1, a warp beam wheel 2 having a warp beam 3 arranged thereon is seen. The warp beam wheel 2 further includes a lifting device 4 for holding a frame 5, on which a warp yarn KF is stretched. Warp yarn 3 and lifting device 4 for retraction
The warp beam wheel 2 with the drive travels on the so-called equipment side of the retractor, and the frame 5 is lifted and suspended by a lifting device 4, where it now occupies the position shown. .

The frame 5 and the warp beam 3 are moved in the longitudinal direction of the base frame 1. During this movement, the warp yarn KF is guided close to the yarn separating stage 6 and
Separated and partitioned. After the separation, the warp yarn is cut to length and transferred to a retraction needle 7, which forms a component of a so-called retraction module.

An image screen 8 is visible alongside the retraction needle 7 and belongs to the operating position and is used for displaying machine functions and machine malfunctions and for data entry. The operating position is part of a so-called programming module and additionally comprises an input stage for manual input of certain functions and processes. The control of the retractor is performed by a control module, which includes a control computer and is arranged in a control box 9. The control computer preferably comprises a separate module computer for each control module, which is controlled and monitored by the control computer.
In addition to the modules already described, the main modules of the pull-in machine also include elementary wire, sheet and sheet modules.

The yarn separating stage 6 for transferring the warp yarn KF to be drawn into the drawing needle 7 and the movement path of the drawing needle 7 extending perpendicularly to the plane of the stretched warp yarn KF determine one plane, which plane is In addition, the above-mentioned equipment side is separated from the so-called release side of the retractor. On the equipment side, the warp yarns and the individual wool elements are supplied, ie the strands or sheets into which the warp yarns are drawn. On the release side, the so-called stitches (strands, sheets and plates) with the drawn in warp can be removed. Immediately after the plane of the warp yarn KF,
The warp monitoring lamina LA is arranged, after which the woven strands LI are arranged, and still further behind the leads. The sheets are stacked in a manual magazine,
And it is suspended in the supply rail 11. On these, the wire stack is
In the separating position for separation and the individual strands are retracted by a retracting needle 7 to retract the warp thread.
Sent to After the retraction is performed, the sheet is released on the release side by the sheet supporting rail 1.
Reach 2

[0013] The strands LI are arranged on rails 13 and are automatically moved to a separating position on them. The strands are then individually conveyed to their retracted position and, after having performed the warp retracting, are distributed on the corresponding weaving shaft 14 on the release side.

The reed is likewise moved over the step and close to the retraction needle, whereby the corresponding plate teeth are opened for retraction. After performing the retraction, the lead WB (
(Partially shown on the right side alongside the weaving shaft 14) is also on the release side.

A so-called toothed wheel 15 is provided on the release side. It is inserted into the base frame at the position shown in the figure with the support members mounted thereon--the sheet metal support rails 12, the weaving shaft 14 and the holding part for the leads--and, after retraction, has a warp thread. I support.

The above functions are distributed to a plurality of modules, and these modules are
They are actually self-contained machines or devices, which are controlled by a common control computer. The already mentioned main module of the retraction machine is preferably modularized again by itself and includes partial modules. This modular configuration is described in Swiss Patent 6,798,871, the disclosure of which is hereby expressly cited.

This FIG. 1 is to be understood purely by way of example: a warp puller in which the device according to the invention for accommodating and holding the stitch elements is incorporated, for example, as a module, is shown in FIG. May differ to a considerable extent from the machines shown in the above.

As can be seen from FIG. 2, the retraction needle forming the main component of the retraction module comprises a gripper belt 16 and a clamp gripper 17 supported thereby. The retraction needle 7 is guided in a path direction (arrow P) in a passage-shaped guide portion 18, and the guide portion extends from the frame 5 in a straight line direction to an arc-shaped end portion 19. The guide part 18 passes through the retraction machine and has a ridge element (thin plate LA,
In the area of the strands LI) and of the leads WB, respectively, they are interrupted, so that the supply of the thread elements to the retracted position and the retraction are carried out until they are transferred to the support member (sheet support rail 12 or woven shaft 14). Of the warp yarn into the lead WB (so-called plate insertion).

The supply of the sheet LA or the wire LI to the drawing-in position and its subsequent feeding until it is transferred to the respective support members are carried out by a partial module, a sheet distribution LD or a wire distribution H
D. Both partial modules LD or HD deliver their successively or stepwise fed wool elements, send them to the retracting position, and after the warp retracting continue to the transferring position, where the In other words, basically, the same function is performed by transferring to the thin plate contact rail 12 or the woven shaft 14.

FIG. 3 shows a spatial partial view of the device 20 for containing, holding and distributing the sheet metal as a partial module in a warp pull-in machine. The head 22 for containing, holding and transferring the wedge elements movably arranged about the axis of rotation 21, in particular the sheets for the loom, comprises four devices 23, which are arranged with respect to the axis of rotation 21. And are symmetrically arranged. Each of the four devices shown for accommodating and holding the wool elements, in particular the sheets for the loom, has two holding surfaces 2 facing each other.
4, 25. The first holding surface 24 is connected to a first piston 26, which is movably arranged in a first cylinder 28. The second holding surface 25 is connected to a second piston 27, which is movably arranged in a second cylinder 29. At this time, the first and second cylinders 28, 2
9 is arranged such that the application of fluid to the pistons 26, 27 causes the holding surfaces 24, 25 of both pistons to move away from each other.

The basics of the operation of these devices 23 for accommodating and holding the whip elements will be explained in detail with reference to FIG.

A first piston 26 simultaneously serves as a second cylinder 29 for a second piston 27
4A is evident from FIG. At that time, the first cylinder 28 and the second cylinder 29 are arranged in a pressure conduit so that the action of the first piston 26 (large arrow) causes the action of the second piston 27 (small arrow) by the same fluid. 30. The load relief passage 54 is connected to the second piston 27.
To allow air to escape from the back of the car. The first and second pistons 26, 27
Here, both holding surfaces 24, 25 are widely separated from each other because they are acted upon by a gaseous or liquid fluid under pressure (small and large arrows). The lamina LA is in the separating position; the other lamina which still have to be separated first are to the right of the angle 36 holding the first holding surface 24 in this figure (not shown). The return elements 31, 31 'formed as coil springs are in a taut position.

It is clear from FIG. 4B that return elements 31, 31 ′ are provided which move both holding surfaces toward one another when the application of fluid to the pistons 26, 27 is stopped. In fact, the pressure of the compressed air used here as the fluid is reduced. However, instead of compressed air, hydraulic oil may be used with a corresponding return member, for example in the form of a hose. In addition, the cylinder or both holding surfaces 24,
The 25 can also be moved by electromagnets or by a mechanical (curved disk) drive, for example, via two pistons which are movable axially opposite or into one another.

Due to its small mass, the smaller second piston 27 (small arrow) is firstly directed by its second holding surface 25 towards the first holding surface 24 of the heavier first piston 26. As a result, the sheet LA is gripped between both holding surfaces. The coil spring 31 'for the second piston 27 is already in the final position, while the coil spring 31 for the first piston 26 has not actually been de-tensioned yet. FIG. 4 does not show that a positioning hook 32 is additionally provided for aligning the wedge element LA stored in place. This locating hook 32 (and guide hook 39) is shown in FIG. 3 and is used to position the lamella (and thus the thread eye) in height and to align it roughly vertically. At this time, the position of the thin plate at the height should be
Due to the mechanical contact between the lower centering element referred to as 2 and the lateral bridging piece 35 separating the thread eye 38 from the contact rail slit 42, the lateral bridging piece is moved via the hook back 41 of the positioning hook. This is done by sliding. At the same time, FIG.
The upper centering element, referred to as the guide hook 39, and the positioning hook 32,
Used as guides, these guides engage between the two longitudinal bridges 40 of the sheet LA and thus make them substantially vertical. This positioning and vertical positioning takes place immediately after the first gripping of the sheet by both holding surfaces 24, 25 and a smaller holding force exerted only by the spring or return element 31 'for the second piston 27. Made possible by The lamella is thus fixedly gripped in this situation, just as it is moved into the correct position and position, but without being lost.

This is central to the invention, but besides the secure holding and feeding of the sheet, the thread centering plays an important role, so that the application of the positioning hook 32 and / or the guiding hook 39 ( In addition to (indirect positioning)-an additional or alternative configuration of thread eye centering also involves the insertion of a sensor into the thread eye (direct positioning): non-contact thread eye centering in this way A light beam or a bundle of light beams is guided through the thread eye, with the detector on the other side of the strand monitoring whether the light beam has passed or not passed through the thread eye . In the mechanical configuration of thread eye centering, a pin snaps into the thread eye and a detector monitors the position of this pin. In both arrangements, it is advantageous to keep the lamellas at an optimum height just for the warp pull-in, so that in the case of a large number of (intact) lamellas, it is ensured that the height is justified. . If the thread eye is to be expanded somewhat (generally upwards), for example by heavy use, the device according to the invention requires, after gripping the sheet, the lower edge of the thread eye to occupy the desired height position. You can lift some according to.

FIG. 4C shows an advantageous configuration of the device according to the invention: the second holding surface 25 is formed by a plate 55-in contrast to the indications in FIGS. 4A and 4B- The plate is connected to the second piston 27 and extends over the housing 56. The plate 55 is in contact with the housing 56 when both pistons 26, 27 have been moved to their final position by the release of the return elements 31, 31 '. This in turn causes that the force exerted by both return elements 31 (large arrow), 31 ′ (small arrow) can be sufficient to more securely hold the wrist element LA. This is more reliable in the feeding of the aligned sheets to the drawing-in position 51, during the drawing-in of the warp yarns, in the feeding to the transfer-position 52 and possibly also in the feeding-out position 53. Means more secure retention of the wedge element. Corresponding to the fluid, air configuration, the housing 56 has an additional load relief hole 54 '. When using hydraulic oil, for example, a return conduit is mounted outside the housing 56 in the area of the load relief hole 54 '.

In addition, from FIG. 3, the device 20 comprises, in addition to the rotary head 22 having four devices 23, in addition to a feed element for delivering the wedge element from the rotary head and distributing the wedge element to the support member. Obviously, it has a dispensing slide 33 with hooks 34. An ejector known per se for scraping a sheet from the feed hook is not shown in FIG. The device 20 includes an electronic control unit for controlling the function of the rotary head 22 and the dispensing slide 33, which is connected to a common control computer as well as possible and which is monitored by this. And controlled.

The course of the process for accommodating and holding or distributing the wedge elements, in particular the sheets for a loom, is described in detail, for example using compressed air as the fluid:

In the separating position 50, as shown in FIG. 3 of Swiss Patent No. 687027, the first of the prepared sheets is bent or expanded. The first and second holding surfaces 24, 25 of the device 23 are filled with fluid, preferably compressed air, which presses the first and second cylinders 28, 29, and thereby the first and second cylinders. The pistons are moved away from each other by acting on them. The holding device 37 of the device 23 is thereby opened against the resistance of the return elements 31, 31 'formed as coil springs, as also shown in FIG. 4A.
At this time, the device 23 with the holding device 37 opened is swung about the axis of rotation 21 so that the inflated front sheet can be gripped in the central region. For this purpose, the first holding surface 24 attached to the angle 36
Is carried between the first and the second sheet LA, so that the first sheet is
4 and 25 (see FIG. 4A). The advantages of the device according to the invention are already evident here: the wide opening of the holding device 37 makes it possible to grip without difficulty even thin sheets having a very large deviation from the expected position.
Extreme positional tolerances of the inflated sheet also have little effect on the secure grip of the sheet LA.

At this time, the pressure of the fluid on the first and second pistons 26 and 27
25 are reduced towards each other-driven by the spring force of the return elements 31 (large arrows in FIG. 4B), 31 '(small arrows in FIG. 4B): the holding device 37 is closed. Due to the significantly smaller mass of the second piston 27, it moves forward faster (in the direction of the small arrow, as shown in FIG. 4B) than the first piston 26, which is simultaneously formed as a second cylinder 29. . This means that the sheet LA is first gripped by the device 23 and then only released from the separating position. Only after the holding device 37 has closed does the first piston 2
6 also returns rapidly (in the direction of the arrow, as shown in FIG. 4C), at which time the sheet is moved away from the separating position and at the same time is brought into position in the device. Alignment at a given location is important. This is because the exact position of the thread eye 38 of the sheet LA is carried to the height or level of the retraction needle 7.

The alignment of the sheets is caused by the positioning hooks 32 and the guide hooks 39,
They are both mounted on the first cylinder 28. The return force of the spring 31 is such that the positioning hook 32 acts on the lower edge of the contact rail slit 42 and pulls the sheet downward by means of its hook back 41 which is obliquely flat, so that the first cylinder is completely When the vehicle returns, it also aligns the sheet. Movement of the lamina LA between the holding surfaces 24, 25 is possible because the return force exerted by the spring 31 'is smaller than that of the spring 31. However, the movement is actually carried out in a controlled manner since the guide hooks 39 as well as the positioning hooks 32 engage in the contact rail slits 42 between the longitudinal bridging pieces 40, so that the movement of the thin plate actually gripped parallel downwards is performed. Only can do.

Preferably, simultaneously with the alignment of the grabbed sheet, the rotating head 22 is rotated by 90 °, so that the grabbed sheet is fed to its retracted position or to the retracted position 51.
Since the rotating head 22 comprises four identical devices 23, at the same time the next open holding device 37 (corresponding to FIG. 4A) is arranged on the next—albeit folded at this time—sheet. When the lamella is located at the retracted position 51, the warp is pulled through the eye 38 of the lamella LA.

During the retraction and also during the subsequent feeding to the transfer position 52, the sheet is held between the two holding surfaces 24, 25 and by the two hooks 32, 39 in the longitudinal bridging piece 40.
It is securely held between. Feeding to the transfer position 52 is performed again by the rotation axis 21.
Is carried out by a quarter rotation of the head 22 around the head. In the transfer position, the sheet LA is accommodated by a feed hook 34 arranged on a dispensing slide 33, from which the holding device 37 of the device 23 can be opened. The feed hook 34 is moved out of the holding device 37 in the direction of the arrow by the dispensing slide 33 and is fed until the sheet can be delivered to a predetermined support by means of an ejector. Only one support member in the form of a sheet support rail or sheet contact rail 12 or a woven shaft 14 (if wires are to be distributed) can be provided for accommodating the wedge element. However, two, three or many support members may be provided. Distribution slide 33
The sheet can be transferred to any support member for the receipt of the wedge element according to the invention, with the jump report being clearly possible in any sequence and order.

A fourth position which can be occupied when the device rotates stepwise around the axis 21 can also be considered to be referred to as a throw position 53. Sheets which are thus monitored for their shape by the monitoring device (not shown) used for this purpose and which are found to be unsuitable for subsequent use-for example due to too large deformation- In the unloading position, it can be discarded in a container (not shown). The rotating head 22 with the four devices 23 is then moved into four defined positions, respectively -separation-50, retraction-51, delivery-52 and delivery position 53-.
At the same time, the device 23 is an advantageous configuration. However, without having to abandon this possibility, it is also possible to consider a swivel 22 having three, two or even only one device 23.

When the projecting position 53 is omitted, the rotary head 22 having only three devices
Can be used. At this time, it is up to the expert to arrange the three devices in a similar manner symmetrically with respect to the axis of rotation 21 or in another manner which has been found suitable. Preferably, the synchronization of the movements of the rotating head 22, the pistons 26, 27; the dispensing slide 33, the feed hooks 34 and the ejectors is controlled or regulated via electronics which also monitor the retraction needle. If the control and mechanical properties of the dispensing slide 33 allow,-in order to increase the processing speed-a rotating head 22 with more than four devices 23 can be provided. It is up to the expert how to group the devices 23 around the axis 21 and which rocking radius (spacing of the gripped strand relative to the axis of rotation). To additionally increase the capacity of the device 20, a second dispensing slide 33 may be provided. The configuration of the drive of the rotary head 22 and the dispensing slide 33, and the configuration of their control, are in the hands of experts in important technical fields here and need not be described in detail.

The advantage of the device according to the invention or the method according to the invention is, inter alia, that the lamellas are defined in a defined position following the storage in the separating position 50 during retraction and until delivery by the dispensing slide. Evident from the fact that it is held securely by the clamp and protects the retraction device since it does not contact the sheet eye.
