Description

[Detailed description of the invention] A device that introduces warp threads into the reed The invention relates to a device for introducing warp threads into a reed according to the preamble of claim 1.

The contents of German Patent Publication No. 32 32 631 indicate a device of this type. . In this device, the top sinker is inserted between the first reed blades of the reed, and then The needle is inserted between these reeds, the warp thread is passed to the needle, and this warp thread is is drawn through the first reed feather. The base of the device has the ability to move in the axial direction with respect to the base. A possible shaft is mounted on which a fixed sinker and a stop are attached. A coil spring is provided between the stopper and the base. top sinker When the needle and needle are inserted between the first reed blades of the aforementioned reed, the cam plate comes into contact with the stopper and This ensures that this stopper, together with the shaft and fixed sinker, is relative to the base and the coil is It is moved by one section between the reed feathers against the elasticity of the springs. Fixed screen after this move is finished. The sinker performs a rocking motion, and in this rocking motion, the fixed sinker moves against the second reed wing of the reed. Insert between. At the same time, the top sinker is inserted into the first debris after the needle has completed its return movement. The base moves along the reed along with the top sinker and needle. The spring moves the reed by one section. In this one section, the stopper is placed in front of the axis. This corresponds to the movement in which the sinker slides with the fixed sinker and biases the spring. Then top The pushinker performs a swinging motion and is inserted between the third reed blades of the reed. This third reed hama is adjacent to the first reed, and the top sinker is inserted in front of it.

The needle then moves, the fixed sinker disengages from the second reed, and then The above-mentioned work process is repeated, but at this time the fixed sinker is placed between the second reed feathers. Insert between the adjacent fourth reed blades.

According to this known device The warp threads are placed on a reed that has a gap of about 30 reeds, that is, a measurement of 30 reeds. Can pass. It is possible to thread warp threads between up to 60 reed feathers in one minute of light. Ru.

However, it becomes necessary to thread the warp threads through a reed having even finer reed feather divisions.

Reeds of this type are used, for example, for silk fabrics and wire fabrics. For such a fine reed Threading the warp yarns has traditionally required manual introduction of the warp yarns one by one.

This is extremely arduous work, and only a few people are able to do it. , and prone to mistakes. In other words, the warp threads may not be passed between certain reed feathers, Or two warp threads may be passed between one reed feather.

In the case of reeds, the reed blades are precisely connected to each other between the pitch, tin and plastic strips. They often do not extend parallel to each other, and the division between the reed feathers is not necessarily constant over the entire length of the reed. Often not.

In the known device, the top sinker and the fixed sinker each perform a swinging motion. reed If the division between the reed feathers is not accurate and/or the reed is in a slightly slanted position If one or the other sinker touches the reed blades or is inserted between the wrong reed blades, Enter. The reason for this is, first of all, the rocking motion of the sinker.

Furthermore, in the case of known devices, if the top sinker is inserted into the reed, it is fixed. At the end of the sinker's movement relative to the base, and when the fixed sinker is inserted between the reed feathers, If the distance between both sinkers is correct at the end of the movement with respect to the fixed sinker of the base. The disadvantage is that it is not exactly an integral multiple of the reed-to-wing division. Therefore, the sinker If you insert the sinkers into the reeds at the same time, the sinkers will not be accurately centered between the reed blades. . Therefore, in this case as well, especially in the case of a reed with fine divisions, one syntax The car hits the reed or catches the wrong reed.

In the case of the known device, no means are provided for adjusting the distance between the sinkers.

The movement of the fixed sinker with respect to the base is also controlled by the cam plate that comes into contact with the stopper. It is caused by The cam plate acts on the stopper and thereby supports the fixed sinker. The steps acting on the movable shaft are always the same. This device has various divisions If you plan to use it on a reed, use a cam plate that matches the category. is necessary. In the case of reeds with particularly fine divisions, the cam stroke is 1 minute between the reed blades. Must match the category exactly.

The object of the invention is to improve a device of the type mentioned at the outset, having the finest divisions. It is an object of the present invention to provide a device capable of passing warp threads through a reed.

This problem is solved by the features of claim 1.

Preferred embodiments are set out in the dependent claims.

Next, embodiments will be described in detail using the drawings.

Figure 1 is a perspective view of the main part of the device, Figure 2 is a front view of the knife-shaped sinker, and Figure 3 is a perspective view of the main part of the device. FIG. 4 is a side view of the sinker and a perspective view of another embodiment of the sinker holder.

In the device shown in FIG. 1, the needle and its operating mechanism are not shown. These parts and and its functionality corresponds to that described in DE 32 32 631 . The same applies to the sinker, needle base, and spring.

Two rails 1, 1 and 1.2 are provided on the base 3 of the device, and these rails are It extends perpendicularly to the surface of the reed (not shown).

A holder 4 supporting the top sinker 22 is guided on these rails 1.1 and 1.2. has been done. Parallel to these two rails 1.1 and 1.2 extending in parallel, Two rails 2.1 and 2.2 extend, on which a fixed sinker 1 is mounted. Another holder 5 supporting 1 is guided. These two other rails 2.1 and 2. 2 is fixed to block 7, and this block 7 can further slide in the axial direction. A fixed shaft 6 extends perpendicularly to the rails 2.1 and 2.2. ing. The block 7 is mounted on a rail 8 parallel to the axis 6 and connected to the base 3. Therefore, you are advised. A hollow shaft 10 is provided on the shaft 6, and this hollow shaft 1 0 can reciprocate in the axial direction with respect to the base 3 in the direction of the arrow 13 together with the shaft 6. I can do it. For this purpose, the hollow shaft 10 has holes 14.1 and 14 formed in the wall of the base 3. ．． It is supported by a shaft with plenty of room inside the 2.

A stopper 9 is fixedly arranged on the hollow shaft 10. This stopper 9 and base 3 A coil spring 12 is arranged between the wall 3.1. One end of the hollow shaft 10 is slotted. and is surrounded by a tightening device 15. The tightening device is tightened Then, the hollow shaft 10 is fastened onto the shaft 6. When the tightening device is loosened, the shaft 6 can be moved axially with respect to the hollow shaft 10.

On the opposite side of the stopper 9 from the spring 12, there is a two-arm arm extending approximately perpendicularly to the shaft 6. One arm 16 of the bar 17 is in contact. The other arm 18 of the lever 17 is It is engaged with a rotatable cam plate 19 supported within the base 3. This cam plate 19 is rotatable but cannot move axially. The cam plate 19 protrudes in the axial direction. A cam 20 is formed.

A swing shaft 21 of the lever 17 is arranged on a block 23. inside block 23 A threaded spindle 24 is screwed together, and the threaded spindle 24 is movable in the axial direction. It is supported by the base 3 so that it cannot move. The threaded spindle 24 is connected to the shaft 6 and parallel to each other and thus extend approximately at right angles to the lever 17. therefore The swing axis 21 can be moved parallel to the axis 6.

The holder 4 is connected to an angle lever rotatably supported on the base 3 through the mouth-shaped slit 25.1. 26,1. The other end of this angle lever 26 can be rotated to the base 3. The cam 27 is in contact with the cam 27 which is supported by the cam 27.

The holder 5 is also engaged with the angle levers 26 and 2 through the mouth-shaped slit 25.2. The angle lever 26,2 corresponds to the angle lever 26,1, and the other end is also in contact with the cam. This cam corresponds to cam 27, but the shape and shape of the cam and cam positions are different.

This device works as follows. In other words, the cam 27 moves the angle lever 26,1. The holder 4 is rotated clockwise so that the holder 4 and the top sinker 22 are attached to the rail. 1.1 and 1.2 in the direction of arrow 28.1. At this time, the top The anchor 22 is inserted between the first reed blades (more specifically, the reed blade gap). top sinker -22, the fixed sinker 11 is disengaged from the reed. Top After the sinker 22 is introduced between the first reed blades, the cam 2 of the rotatable cam plate 19 0 engages the arm 18 of the lever 17, thereby causing the arm 16 to release the spring 12. Move the stopper 9 to the right against the force. This movement to the right, indicated by arrow 13, Empty shaft 10, shaft 6, tightening device 15, rails 2.1 and 2.2 and holder 5 This is done for the block 7 as well as the fixed sinker 11. At that time, the spring 12 Forced.

After the top sinker 22 is inserted between the first reed blades and widens the first reed blades, Then, a needle (not shown) moves between the reed feathers.

The moving movement of the fixed sinker 11 brought about by the cam 20 moves one segment between the reed wings. corresponds to When the fixed sinker 11 has finished moving to the right as indicated by the arrow 13, the anchor The cam that operates the angle levers 26 and 2 swings the angle levers clockwise, Fixed sinker 11 is thereby moved between rails 2.1 and 2.1 as indicated by arrow 29.1. 2, and at this time it is inserted between the second reed blades of the reed. Konoto At this time, the top sinker 22 is still engaged with the first reed blade.

Before the fixed sinker 11 is inserted between the second reed, the needles are inserted with the received warp threads. As is well-known in Pushinker 22 has been introduced. The fixed sinker 11 is inserted between the second reed blades. At the same time, the angle lever 26,1 is swung counterclockwise by the cam 27. Then, the holder 4 performs a return movement as indicated by arrow 28.2. Therefore, the top The anchor 22 is disengaged from the reed.

The top sinker 22 and needle are disengaged from the reed, but the fixed sinker 11 is inserted. Therefore, the spring 12 connects the base 3 via the base wall 3.1 to one section between the reed blades. move the distance, that is, the part.

After this movement of the base 3 is completed, the angle lever 26,1 is moved again by the cam 27. Since the holder 4 and the top sinker 22 are rotated clockwise, the holder 4 and the top sinker 22 move in the direction of arrow 28.1. At this time, the top sinker 22 is inserted between the third reed blades. this The third reed space is adjacent to the first reed space, and the top sinker is placed in front of this third reed space. It is inserted between the reed feathers of No. 1. Top sinker 22 is inserted between the adjacent third reed feathers After the angle levers 26, 2 are swung counterclockwise, the holder 5 along rails 2.1 and 2.2 with fixed sinker 11 in the direction of arrow 29.2 Moving. Therefore, the fixed sinker 11 is inserted between the second reed feathers inserted before it. be disengaged from the

The above-mentioned operations are then repeated. The shaft 6 is rotated by the cam 20 of the rotating cam plate 19. It is newly moved to the right as shown by the arrow 13, and at this time the spring 12 is energized. The fixed sinker 11 is moved to the right by one reed interval. The needle is top sinker 2 The fixed sinker moves into the third reed space widened by 2 and exits there. 11 moves in the direction of arrow 29.1 and is adjacent to the second reed blade introduced in front of it. It is inserted between the fourth reed feathers. The top sinker 22 engages with the third reed blade. The base 3 is inserted together with the top sinker 22 and the needle by the pressure of the spring 12. The fixed sinker is moved in one direction by one section between the reed blades.

The cams that operate the cam plate 19, cam 27, and angle levers 26, 2 are the same. It rotates in time.

The fixed sinker 11 and the top sinker 22 simultaneously engaged with the reed blades of the reed. Sometimes, the distance from each other is such that both sinkers are positioned in the middle between the reed feathers each introduced. selected to be placed. Therefore, the distance between both sinkers is exactly the same as the vibe section. Corresponds to an integer multiple. To do this, a tightening device 15 is used. Both sides When the anchors 11 and 22 are inserted between the reed blades and the tightening device 15 is released, The fixed sinker 11 can be adjusted relative to the top sinker 22. That's called The reason is that the shaft 6 is movable relative to the hollow shaft 10, and thereby the shaft 6 is movable relative to the lever 17. This is because it becomes a movement. If this adjustment is made at the beginning of introducing the warp threads into the reed, the tightening Then the device 15 is tightened, whereby the shaft 6 is fixedly connected to the hollow shaft 10. Ru.

The axial strokes of the shafts 6 and 10 and the accompanying axial strokes of the fixed sinker 11 are: Continuous adjustment is possible using the threaded spindle 24. Block 23 When adjusted to the right by the same spindle 24, the entire stroke of the cam 20 of the cam plate 19 acts on the lever arm 18, so the shafts 6, 10 and the fixed sinker 11 are connected to the base 3. The maximum possible distance corresponding to one division between the coarse reed blades is made with respect to the reed. Block When the cam 23 is moved to the left, the rate at which the cam 20 acts on the lever arm 18 becomes smaller. Therefore, the movement step performed by the fixed sinker 11 becomes smaller. This is a reed This corresponds to one detailed classification. When the cam 20 no longer contacts the lever arm 18, The stroke becomes zero. Therefore, by 240 revolutions of the spindle and with it By moving the rotating shaft 21 of the lever 17 parallel to the shaft 6, it is fixed. The sinker 11 can be adjusted steplessly in the direction of the arrow 13, and accordingly. It can be adapted to each reed feather division.

Figures 2 and 3 show the preferred shapes of the top sinker and fixed sinker. be. As is clear from the figure, the sinker is placed just above the lower flange of the reed. between the reed blades of the reed, thus sensing the parallelism errors that may occur in the reed blades of the reed. Insert it between the reed feathers of the reed at the wrong place.

The rear region 30 of the sinker has a rectangular base. There are sharp edges below the front area. 31 is provided. The edge 31 extends diagonally upward from the lower point 32. As shown in FIG. 2, the slope 33 becomes narrower toward the tip 32.

The tip 32 is inserted between the reed blades, and the pipe is gradually removed due to the conical slope 33. It will be expanded to . In this way, the reed was widened by the top sinker 11. The needle is introduced between the reed feathers.

For tightening, use the device shown in Figure 4 instead of device 15, and adjust between sinkers 11 and 22. It is also possible to perform a section. This device consists of a fixed sinker 11 and/or a top It is provided in the sinker 22. In the illustrated range, it is provided on the fixed sinker 11. .

The fixed sinker 11 is fastened to a member 34, and the member itself is The clamp is fixed within the holder 5. Holder 5 is divided into two for this purpose. , the image parts 5.1 and 5.2 are mutually connected by bolts introduced into the holes 35.1 and 35.2. is combined with An L-shaped notch is formed in the holder portion 5.1. A tightening member 34 is disposed within the notch. Tighten the member 34 and the holder part 5. 1 is orthogonal to the axis 6 by means of a wedge-shaped mesh 36 extending parallel to the axis 6. Can be fixed in a corner.

Both sinkers 11.22 are inserted between the reed blades of the reed, respectively, and the holes 35.1 and 35. When the bolt screwed into the bolt 2 is loosened, the tightening piece 34 is released. Then Tighten the fixed sinker 11 with piece 34 in the same way as when the device 15 is loosened. Both can be adjusted in the axial direction of the shaft 6 with respect to the holder 5.
