Abstract

The invention relates to a warp drawing machine for arranging harness elements such strands or lamellae on warps. Such a warp drawing machine is normally fitted with a device for receiving a stack of individualized harness elements and for feeding harness elements to a separating device, wherein the separating device has at least one separating and one individualizing member which separate the first harness element from the stack and guides the harness element already separated from the stack in the direction of a transport device for further separation from the stack. The transport device then brings the harness element to a warp drawing station. A warp drawing machine also normally includes at least one retaining means that can be placed against the stack. In order to reduce the structure of said machine while ensuring high functional safety, displacement means (64) of an individualizing organ (30) of the separating device and at least one retaining means (70) in a transfer means (60) are structurally assembled together and can move together in a direction deviating from the direction of displacement (25) of the harness elements.

Description

TECHNICAL DEVICE AND METHOD FOR TRANSFERRING INDIVIDUAL HARNESS ELEMENTS TO A TRANSPORT DEVICE}

In order to weave, orna elements such as carp or dropper are inclined by warp threading means. This is generally done due to the pile of each ordinal element fed to the separation station. Separation stations of this kind for carp or dropper are known in the art. Although the separation station for the carp is different from the dropper's separation station by design, a common feature is to pull the up and down elements in each case, in particular in each case by removing the best two elements from the pile up and down the transfer device. To move to. The individual separate up and down elements are then moved to another position in the warp thread where the up and down device is aligned to the slope. In order for the warp threader to operate without failure, it is important for the individual up and down elements to be pulled out of the corresponding pile by each separating station, to be separated separately, and to move at the scheduled time.

Thus, for example, in a warp tube of this type, the carp is first separated from the pile by a movable separating knife and driven dummy compactor means. The carp is removed from the dummy simultaneously with the two conveying members and replaced by two conveying bands. The dummy compactor is supported in advance against the dummy so that the dummy is held.

In the separation devices of the prior art, it is considered a disadvantage that the moving individual parts have a relatively large number and each must have its own drive. It is also considered to be a disadvantage that the operating stability depends on precise movement in synchronization with the individual components of the separation device.

The present invention relates to a warp tube for an ordinal element device, such as a carp or dropper, on an incline, comprising a device for receiving a pile of individually separable ordary elements and a device for supplying the ordary elements to the separating device, The separating device has at least one release member and separating member that separates the headmost up and down element from the dummy, and then moves the already separated up and down element from the dummy to the transfer device, in order to escape again from the dummy, Moves the up and down elements to the warp tube, and there is at least one retaining means that can bear against the pile. In addition, the invention also relates to the method for claim 12 described above.

It is an object of the present invention to simplify the design of warp threaders and to have high operational stability.

The warp warp mentioned in the introduction can be achieved as follows. In the at least one retaining element and the detachment member of the separating device the displacement means are structurally or physically combined with each other in the conveying means, both of which can move together in a direction away from the direction of displacement of the up and down elements.

In the separating device of the warp warp, on the one hand it functions to "separate the leading carp and move one of its rails to the conveying means," and on the other hand to "keep the carp." Performed by subassemblies. According to the invention, the two operatively connected means are connected in one piece to each other to perform these two functions. You can also use only one drive for both functions. As the number of defect sensitive components decreases, the operational stability of the device for the present invention can be increased.

The one-piece rigid body connection, preferably provided between the displacement means and the retaining means, may have the further advantage that the two means are permanently determined to move synchronously with each other. The two components of the device cannot move relative to each other during operation, especially when they are monolithic or rigidly connected to one another. Thus increasing operational stability.

A simple design is achieved when the displacement and retaining means are integrated in the lever so as to be rotatable about the axis. The lever has at least two protrusions, one protrusion forming an integrated part of the displacement means and the other protrusion forming an integrated part of the retaining means.

In order to perform two functions of "displacement of the leading carp" and "holding the carp", the lever vibrates between two dead points in the direction opposite to the direction of rotation or in the direction of rotation. These two functions can be effectively combined with such levers as long as the direction of movement has no element in the displacement direction of the infant.

The object of the present invention is achieved by means of the method and apparatus according to claims 10 and 12.

Also, the precision mentioned in the present invention can be made from the dependent clause.

The invention has been described in more detail with reference to the illustrative embodiments shown in the drawings.

1 shows a basic design of a warp threader which may also be used in the present invention. This machine consists of several subassemblies which are aligned with the base stand 1, each forming a functional module. The warp beam conveyor 2, on which the warp beams 3 are arranged, is in front of the base stand 1. The warp beam conveyor 2 also consists of a lifting device 4 for fixing the frame 5 on which the warp KF is tensioned. The warp beam conveyor 2 of the lifting device 4 together with the warp beam 3 moves up to a place called the installation side of the hole, and the frame 5 is lifted by the lifting device 4 to make the diameter. It is suspended from where it is expected to be lifted and shown.

The frame 5 and the warp beam 3 are moved to the base stand 1 in the longitudinal axis direction. While this displacement takes place, the slope KF is led to the previous thread release step 6 and at the same time separates and divides. After being separated, the warp is guided to the penetrating needle 7 which is cut and forms an integrated part called a recovery module.

This can be seen through the video screen 8 at the operating station next to the telescopic needle 7, which displays the machine's operation, failure and data entry. An operating station is called a programming module and consists of input stages for manual entry of a specific function or sequence. The tuber is controlled by control module means composed of a control computer and aligned to the control box 9. This control computer preferably consists of a separate module computer which is controlled and monitored by the control computer for each functional module. The main module of the game machine includes a reed module, dropper and carp in addition to the module already mentioned.

In the warp escape step 6 the warp KF is passed through the diameter needle 7 and the path of the needle moves perpendicular to the plane of the tensioned warp KF, already mentioned in the so-called disassembly side of the warp machine. Form a plane to separate the installation side. On the installation side, the ingot or dropper individual up and down elements and the incline, which are inclined, are fed. On the disassembly side, so-called up and down devices (carp, dropper, body) come out with the diameter inclination. The warp stop dropper (LA) aligns immediately behind the plane of the slope (KF), behind the carp (LI) and behind the body (WB) far from the rear. After the inclination has passed, the dropper reaches the disassembly side of the dropper feed rail 12.

The carp LI is fixed to another feeder and is automatically replaced by a separator in the present invention in connection with the following description. Here, the carp is individually brought to its diameter position, and after the warp diameter has occurred, it is distributed in the corresponding carp frame 14 on the disassembly side.

The body WB is moved to the next step after the telescopic needle, and the corresponding body tooth is open for telescopic. After the passage, the body WB (shown partly to the right of the carp frame 14) is likewise located on the disassembly side.

What is called the up and down device feeder 15 is provided in the disassembly side surface. In particular, it is pushed to the base stand, which is the position shown with the transport member tightly fastened to the dropper conveyor lane 12, the carp frame 14 and the fixing device of the body, and conveys the device up and down with the slope after the passage.

The functions described correspond to a number of modules that make up a system or automatic machine controlled by a common control computer. The already mentioned main module of the competition is preferably a modular design itself and consists of sub-modules. The modular design is known from Swiss patent CH 679 871 and is hereby incorporated by reference.

1 is for illustration only. In inclined tillers, in connection with the present invention a device for the transport of separate ordinal elements has to be installed, for example as a module that can be described literally or in detail which can be quite different from the machine shown in FIG. .

As assembled in FIG. 2, the diameter needle 7 forms the main integral part of the diameter module, which consists of a gripper band 16 and a fixed gripper 17 conveyed thereto. The penetrating needle 7 moves in a reciprocating direction (arrow P) in a channel such as a guide 18, which guides the arched end 19 from the frame 5 in a straight direction. Stretched out The guide 18 passes through the tube, where it is cut off at the part with the up and down device (dropper LA, Ina LI) and at the part with the body WB, which is supplied to the down position. It is to convey them, and to move them to the conveying member (dropper conveyer 12 or the carp frame 14) after diameter, and to move until it pulls incline to the body WB.

The dropper LA or the carp LI is supplied to a diameter position, and these are conveyed until each conveying member is moved by the dropper dispenser LD or the carp dispenser HD means. In order for the two submodules to work stably, each lift mechanism element must be supplied individually and at the correct time. The two sub-modules LD and LH basically perform the same function. The two ore modules LD and LH are sequentially transported to the telescopic position by transporting the up and down elements supplied thereto. In other words, the dropper conveying lane 12 or the carp frame 14 is conveyed.

3 shows a supply device 20 for warp threading. The feeder has two sets of oblique conveying rails 21, 22 for the carp LI. The carp dummy 23 is arranged in two lanes, and the carp LI is pushed in the loops of the respective upper and lower rails. Carp LI is made to move in the direction parallel to the longitudinal axis of the rail (in the direction of arrow 24). Although not shown, the weight in the form of a slide aligned to move on the lower rail 21 portion bears the last carp of the pile 23. The arrow 24 therefore also indicates the effective direction of the pressure exerted on the dummy 23 by the slide. The angle where the two rails are slanted relative to the horizontal is chosen irrespective of the number of relies (LI) remaining in the ream pile (23), and the best head car (25) is almost relative to the separator (26). Withstands constant force. A feeder 20 of this type is known from Swiss patent application 1998 1864/98 and used by reference in the present invention.

FIG. 3 schematically shows the breakaway members 30 and 31 at the lower ends 21a and 22a of the two rails 21 and 22, respectively. 3 also shows the separating member 32 in dashed dashed line. The two separating members 30 and 31 separate the head of the carp 25 from the carp pile 23 and transfer the carp to the ends 21a and 22a of the rails 21 and 22. The separating member 32 then separates the carp 25 from the dummy 23 for the next step. At the rail end, each carp is conveyed from the separating device 26 to the conveying means 33.

In an illustrative embodiment, the conveying means 33 has two circular movement bands 34, 35, but the receiving spike 26 is arranged therein. The carp LI is pushed into the receiving spikes 36 of the upper and lower conveying bands 34 and 35 due to the release members 30 and 31 together with the ring shape thereof. The direction of movement of the conveying bands 34, 35, partly shown in cross section, is perpendicular to the drawing plane of FIG. 3. Therefore, the two transfer bands 34, 35 move in the plane by 37 in FIG. Therefore, the leading head carp 25 is firmly fixed to the transfer bands 34 and 35, and each receiving spike 36 of the lower transfer band 35 has an upper end opposite to the spring 38 force at the time when the carp is transferred. It can be moved in the direction of the conveying band 34. For example, the receiving spike can be transferred to an air cylinder means acting on it (not shown).

In FIG. 4, the edge 41 of the separating knife 40 in the separating member 32 is squeezed laterally with respect to the leading head carp 25 to separate the leading head carp 25 from the dummy 23. . As a result, the head of the chief 25 is in a deflected or bent direction, unlike the direction 42 perpendicular to the conveying direction (arrow 24). The nose 43 of the dummy compactor 45 in the separating member 32 rotates along the axis of rotation at the same time in the direction of the arrow 44 between the best head Ina and the dummy 23 compressed to the side. The dummy compactor 45 rotates back with a time difference for the return stroke of the knife 40 and moves the head head caravan to the opposite side of the separation knife 40. In this position, it is bent again by the carp. Separation members of this type are known from the applicant's international patent application PCT / CH98 / 00400. The contents of this application are presented for reference to match the function and design of the separating member 32.

The upper and lower release members 30 and 31 can be used continuously. In FIG. 5 and FIG. 6, the lower end release member 31 is composed of an air cylinder 48, and the piston rod 49 is rotatably engaged with the rotary lever 40 by a bearing contact 47. In order to move the head head ingot 25 in the direction of the lower feed band 35, the piston rod 49 must be pushed into the cylinder 48 from the maximum extended position shown in FIG. Since the rotary lever 50 moves along the home link (not shown), the driver 51 is in a free position, and the lever 50 is at the same time the direction of the moving band 35 and the conveying direction ( At the intersection of 24, rotate along the circular arch shape. Due to the fluid variation of the carp by the separating knife, the dummy compactor is displaced and the best head car is released, which is brought before the driver 51 of the lever 50. The rotary lever 50 therefore turns over the already best head carp 25 while the lever rotates (arrow 53 in FIG. 5). The driver 51 pushes the ingot 25 in the lower ring of the lower conveyor rail 22 into the receiving spike 36 of the lower conveying band 35.

7 and 8 show the release member 30 in the top conveyor lane 21. For the sake of clarity, no separation member or bottom release member or bottom conveyor rail in FIG. 8 is shown. The upper detachment member 30 is composed of a conveying means designed as a double protrusion lever (61). The lever 61 is provided at the top end between the two projections together with the rotatable shaft 62. To operate the rotating member, although not shown, an air cylinder is connected to the shaft 62 of the lever 61 via a groove link. The rotary shaft 62 is approximately horizontal and is aligned above the end 21a of the rail 21 opposite the transfer band 34. Since the rotary shaft 62 lies in the plane of the head extending in the longitudinal axis of the two lanes 21, 22, the rotating member is perpendicular to this plane. This plane 63 coincides with the plane of the figure in FIG. 7.

The first bent limb of the lever is designed as a displacement means 64 and serves to move the leading head carp 25 in the direction of the feed bands 34, 35. For this purpose, the face of the lever 61 is located facing the conveying band, which is designed with an oblique displacement face 65. The displacement surface 65 operates only on the rim part, in particular up to the free end 67 of the rim up to the kink 66 just below the rail 21.

The displacement surface 65 is inclined as if the lower free end 67 of the lever is far from the most plane 68 formed by the transfer bands 34, 35. The distance between the lever 61 and the plane 68 decreases starting with the free end 67 of the first rim and continuing to the kink 66 of the rim. Conversely, the face 69 (back) of the lever 61 is located opposite to the pile 23, parallel to the plane 68 and perpendicular to the rotary shaft 62 and perpendicular to it. Plane 68 and face 69 should be at an angle of about 10 degrees.

The second rim is provided with retaining means 70 and is located above the end 21a of the upper rail 21. Between the kink 72 and the free end 73, the rim is provided with a retaining portion 74. The retaining portion 74 has a length determined in a direction substantially perpendicular to the plane 63 of the two rails. In a particular rotational position of the lever 61, the pile 23 is held by the wedge-shaped retaining portion 74 on the upper rail 21. As shown in FIG. 7, the retaining portion 74 of the second rim is farther from the plane 68 of the transfer band than the displacement surface 65 of the lever.

The lever 61 rotates as soon as the separation device 26 separates the head of the carp from the pile, which is already pressed by the lower release member 31 to the receiving spike of the lower transport band 35. The lower end of the first rim of the lever (displacement means 64) penetrates between the leading head carp 25 and the carp pile 23. As a result, the first rim is in contact with the face of the carp 25 at a point on its own displacement surface 65, which face is positioned towards the carp pile 23. This step is shown in FIG. The leading head carp 25 is placed at the upper end 25a to the retaining portion 74. Due to the rotational member, the retaining portion 74 releases the leading head carp 25 and the entire pile 23, after which the displacement surface 25 bears the leading head carp 25. However, instead of holding the retaining portion 74, the dummy 23 bears the face 69 of the first rim facing the carp pile 23 below the bottom rail 21.

Due to the continuous rotational movement of the lever 61, the contact point between the carr 25 and the displacement means 64 moves along the displacement surface 65 in the direction of the top ring (end 25a) of the carr 25. Done. In addition, since the displacement surface 65 of the lever is inclined along the plane 68 direction, the lever 61 pushes the ingot together with the upper end 25a in the upper conveying band 34 direction. In this step, the dummy 23 also bears the rear face of the displacement means 64 of the lever 61 and is held by the lever. The displacement plane 65 of the lever should slide along the hed without squeezing or damaging the hed in the transverse direction to the plane of Fig. 7 (to avoid self-locking). The appropriate angle formed to be perpendicular to the displacement plane 65 is chosen depending on the material of the lever and the carp.

After the carp 25 is pressed in the receiving spike 36 of the upper feed band 34 in this way, the lever 61 reaches a maximum deviation (second dead point) and the lever rotates back toward the initial position. do. In this case, the wedge-shaped retaining portion 74 reaches the point where it meets the free end 74a in front of the carp dummy 23, but is not yet in contact with the head of the carp dummy. Because of the offset of the free end 74a with respect to the face 69 in the direction of the feed bands 34, 35, this contact takes place only during the continuous rotational movement of the lever 61 in the direction of the first dead center. . Then, instead of the rear of the displacement means 64, the retaining portion 74 again performs the function of holding the pile. Due to the shape of the lever, the pile is not squeezed laterally while the lever 61 vibrates from the first dead point to the second dead point and does not go back again. After the lever has reached its initial position (first dead point), a new cycle begins, ie a cycle in which the carb of rotation leaves the dummy.

In another embodiment, a dropper separating device provided as a conveying means in connection with the present invention may be supplied.
