Description

The invention relates to a method and an auxiliary device for reading threads into guide members a treatment device for treating the threads and such a treatment device with the features of the preamble of independent claims 7 and 14.

A method for reading threads in a guide member and an auxiliary device and treatment device according to the preambles of claims 7 and 14 are known from DE-A-1 535 181.

In preparation for weaving, individual threads in thread sheets are treated with treatment devices performed, for example, for treating the threads, but also for slip or warping of the threads can serve. A typical treatment for warp threads is that Arbitration.

Such treatment devices are usually provided with guide elements in which the threads are run. For example, up to 16,000 threads can be used for finishing be treated at the same time. Here, e.g. up to 16 threads in 1,000 side by side Gaps in such a management body. Management bodies are, for example Combs or reeds.

If (for example during the sizing process) the warp beams with the threads to be treated empty, they must be replaced by full warp beams. This means that the threads of the new warp beams must be carried out individually by the management bodies. This process is also called reading. Reading up to 16,000 warp threads, for example in several successive management organs is time consuming and can take up to Take 6 hours. During this time, the plant is idle and it is not a productive one Operation of the device possible.

It is therefore an object of the present invention. to avoid the disadvantages of the known in particular a method and an auxiliary device for reading threads create a quick and safe reading of the threads into one or more management bodies allow a device for treating the threads. The method and the auxiliary device should also ensure that the threads in an orderly manner in the management bodies can be read that in particular no crossovers take place. A Another object of the invention is a treatment device with guide members to create which is a simple and quick reading of threads in management bodies allows. The method according to the invention and the auxiliary device should also be based on can be carried out or manufactured in a simple manner and without major modifications to existing ones Treatment devices can be used.

According to the invention, these objects are achieved with a method according to claim 1 and with an auxiliary device and Device with the features of the characterizing part of the independent claims 7 and 14 solved.

The method is used to read threads into guide elements of a treatment device to treat the threads. In particular, the method for reading in warp threads can be for example in a sizing system. The executive bodies are, for example Comb or reed of such a sizing system.

To read the threads, they are read into and on at least one reading comb attached. The threads are then passed through the treatment device with the reading comb drawn. The threads are taken over by the management bodies.

The reading comb forms an auxiliary device for reading the threads. It is enough the threads once in the reading comb and fasten them on the reading comb. So that's it Position of the threads precisely defined. When the reading comb is pulled through the treatment device is, the individual threads can be done without much effort due to their orderly location be introduced directly into the management bodies.

In a preferred embodiment of the method, the reading comb is gradual passed through the treatment device. The movement of the reading comb is interrupted as soon as the reading comb has passed a management body. The reading comb is obtained positioned on the management body before the threads are taken over by the management body become. The threads are thus pulled from the reading comb over the guide element. After that the movement of the threads is interrupted and the threads can be introduced into the guide members become.

In a further preferred exemplary embodiment, the guide members are read in before removed from the path formed for the threads in the treatment device. typically, the guide members can be lowered or raised in the treatment device become. After passing through the reading comb, the guide organs are in the way again moved back for the threads. The threads are taken over by the management bodies.

The method can be used particularly advantageously with a reading comb, the reading gaps for receiving the threads. The arrangement of the reading gaps corresponds to the arrangement of gaps in the executive bodies. The reading comb can also with alignment projections be provided, which extend away from the reading gaps. In the inventive The read-in comb is aligned with the management bodies by the alignment projections are brought into engagement with the gaps of the management bodies. The Alignment projections ensure that the reading gaps of the reading comb match the gaps of the Executive bodies are in alignment. The threads can be handed over safely and easily.

Alignment can be carried out particularly easily if the guide members are moved back whose gaps are pushed over the alignment projections.

The reading comb can be moved particularly easily through the treatment device by it is attached to the remaining threads from a previous treatment process and with the remaining threads are pulled through the device

The auxiliary device according to the invention for reading threads, for example warp threads in management organs of a treatment device for treating the threads is particularly for Implementation of the method mentioned is advantageous. The auxiliary device is a reading comb formed, which has an arrangement for orderly fastening of the threads.

The reading comb is preferably with a plurality of reading gaps arranged next to one another Mistake. The reading gaps serve to pick up the threads. The arrangement of the import gaps is coordinated with the arrangement of the gaps in the management bodies. In order to is a transfer of the threads from the reading gaps of the reading comb into the gaps of the Management bodies possible in an orderly manner.

The reading comb is also advantageous with alignment elements for aligning the reading comb related to the management bodies. This ensures that not only the relative position of the threads to each other but also their position in relation to the guide members is defined.

The alignment elements are typically designed as alignment projections. The alignment tabs preferably extend from the reading gaps and are with the gaps in the Management bodies can be brought into engagement. With the read-in comb aligned with the guide elements the alignment protrusions, the reading gaps in the reading comb and the Gaps with each other.

The reading comb is particularly advantageously designed as a stack of platelets. Here are the first Tiles to form the reading gaps arranged at a distance from each other. Second tile serve as spacers and are arranged between the first plates. The second tiles also advantageously form a contact surface for the threads in the reading gaps. The second plates can also be provided with projections, which act as alignment elements serve. With projections designed in this way it is automatically achieved that the projections aligned with the gaps in the reading. Because the thickness of the spacers. that is the second tile, corresponds to the width of the reading gaps and thus the width of the gaps in the management bodies is adapted, the second plates with their protrusions can be particularly easily in the gaps in management bodies are introduced. To facilitate the introduction, the Projections also have tapered noses.

The read-in comb can also be provided with holding elements for temporary recording and mounting of the reading comb in the receiving devices assigned to the guide members serve.

Alternatively, it is also conceivable to form a reading comb in one piece and the reading gaps by suitable material processing, for example milling or eroding. The Alignment projections can be formed by slices inserted into the reading gaps become. The slices can be combined to form a comb.

Instead of removing the guiding elements from the path for the threads, it is also conceivable that Not to move the guide elements and instead the reading comb for transferring the threads to move and align with the governing bodies.

The inventive treatment device for treating threads is characterized by this that the treatment device is assigned at least one reading comb. The The reading comb can be designed in particular in the manner described. On the The comb can be fastened in an orderly manner. The threads are from governing bodies in the Treatment device can be taken over from the reading comb.

It is advantageous for the management bodies to have at least one pick-up device for temporary use Holding the reading comb assigned. As soon as the reading comb has passed the management organs, the movement of the reading comb is interrupted and this can be held in by means of holding elements the receiving device can be kept precisely positioned.

This arrangement is particularly advantageous if the guide members are removed from the treatment device formed path for the threads are designed to be movable. typically, the governing bodies can be lowered or raised.

This arrangement has the advantage that the reading comb through the treatment device can be pulled until it hits a cradle. The one out of the way for the guide elements moved away from the threads, the movement of the reading comb does not interfere. As soon as the reading comb is positioned in the receiving device, the guide members again in the way for the threads to be moved. The threads are automatically correct in the governing bodies introduced.

The device according to the invention is particularly advantageous if it has multiple frames Includes the threads to be treated, in particular several frames for warp beams. The threads of at least one frame can be read into a reading comb, while the threads of another frame are passed through the treatment device and can be treated. The downtimes of such a treatment device are reduced.

In Figure 1, a treatment device 1 is shown schematically, in which the inventive The method and the auxiliary device according to the invention can be used. The treatment device 1 is used for finishing threads F. The threads are on warp beams held in a frame 5 and fed by the device 1. The device 1 comprises a sizing unit 6, an adjoining dryer 7 and one Broaching machine 8 for winding up the treated threads F. The threads F become continuous conveyed by the treatment device 1, that is to say from the frame 5 to the building machine 8.

Figure 2 shows a plan view of the device 1 according to Figure 1. The threads F are from the frame 5 through the sizing unit 6, the dryer 7 and via unspecified deflection arrangements led to the broaching machine 8. At the same time, a group of threads of treated about 1,000 times 16 threads. Located on each of the 16 warp beams held in frame 5 1,000 threads.

To guide the threads F in the device 1, the latter is provided with various guide elements 2 Mistake. The guide members are designed as combs or reeds through which the threads be performed.

In addition to the frame 5, a further auxiliary frame 5 'is arranged, which also has 16 warp beams contains 1,000 threads each.

The threads F are treated while the frame 5 is in a position P1. At the same time, it is possible to diagrammatically show the threads of the frame 5 'in the position P2 read comb 11 shown.

Thanks to the additional frame 5 'and the reading combs 11, it is possible in position P2 to fasten the threads F 'on the read-in comb 11, while the threads F des in Position P located frame 5 are still treated. As soon as the warp beams on the Frame 5 are empty, the frame 5 is moved to the position P3 and replaced by the frame 5 '. The frame 5 'is shifted from position P2 to P1. The threads of now Full warp beams can easily be inserted into the guide members 2 of the treatment device 1 can be read in by means of the reading comb 11 in direction A through the Treatment device 1 are pulled. With each guide element 2, the reading comb 11 aligned with the guide member 2 and connected to the reading comb 11 Threads F are transferred to the guide member 2, that is, read into it. Under reading in this context, the passage of the threads F through openings or gaps in the Management bodies 2 understood.

FIG. 3 shows a reading comb 11 in a perspective representation. The reading comb 11 exists from a stack 16 of thin platelets. First plates 17 are at a distance a from one another arranged side by side. Second plates 18 are arranged between the first plates 17, that define the distance a. The distance a forms reading gaps 13 between the first Tile 17.

The plates 17, 18 are provided with bores 24 through which a holding device, for example, a pin or a clamp can be made to to hold the stack 16 together.

The reading comb 11 is also provided with a clamping device 15 which against a can be pressed by the first plate 17 and the second plate 18 surface formed together is.

Before threads F of a new warp beam are passed through the device 1, they are in read the comb 11. For this purpose, the threads F through the reading gaps 13 of the reading comb 11 out. For illustrative reasons only a small number of threads are shown. Usually, up to 16 threads are read in each of the reading gaps 13. The strings F extend over the contact surface 19 formed by the surface of the second platelets 18 and over the jointly formed by the first plate 17 and the second plate 19 Surface 26. By pressing the threads F with the clamping device 15 against the Surface 26, the threads F are fixed on the reading comb 11. The fixation is included ordered because the threads F are guided through the reading gaps 13.

The reading comb 11 is also provided with holes 25 through which pins 23, 23a are pluggable. The pins 23 prevent the threads F by themselves from the reading gaps 13 devices. The pin 23a allows the ends of the threads F to be fastened.

The reading comb 11 is also provided with a further bore 22 through which a further pin 23b can be plugged in, to which residual threads R can be attached. The remaining threads R can Threads from a previous treatment process. The reading comb 11 will then pulled with the remaining thread R through the device 1.

Figures 4a and 4b show different embodiments of a reading comb 11 in one Side view.

The reading combs 11 are, in the manner shown in FIG. 3, from a stack of platelets 17, 18 built up. According to the exemplary embodiment in FIG. 4a, the platelets have openings, which form a cavity 21. The plates 17, 18 can be held together by the cavity 21 is poured out. In the exemplary embodiment according to FIG. 4b, the Holes 24 introduced suitable fasteners to hold the plates 17, 18 together. Otherwise the read-in combs from FIG. 4a and FIG. 4b do not differ.

The threads F are the alignment projection 14 and the bearing surface 19 of the second plate 18 through the reading gaps 13 between the first plate 17 performed. The alignment projections 14 serve to align the reading comb with respect to the guide members 2 (see Figures 5, 6 and 8).

The clamping device 15 is shown schematically as a pivotable lever, the one Clamp member 27 presses against the surface 26. Of course, there are other mounting options like knots or wraps.

In the area of the surface 26, the upper edges of the first plates 17 and the second are aligned Plates 18 with each other, so that a closed surface is formed. Outside the surface 26, the platelets 17 protrude from the support surface 19 of the platelets 18, so that between the reading gaps 13 are formed.

To read the threads F through the treatment device 1, as in FIGS. 3, 4a or 4b shown first read the thread sheet into the reading comb. Then the Reading comb 11 with the remaining threads R pulled through the treatment device 1. Once the Reading comb 11 has passed a guide member 2, we the movement of the reading comb 11th temporarily interrupted. Figure 5 shows the reading comb 11 in such a rest position P. Die Rest position P is based on the direction of movement A after the guide member 2. Das Guide member 2 consists of a plurality of juxtaposed slats, between which gaps 3 are formed. To read the threads F into the gaps 3, the Reading comb 11 aligned with the guide members 2. To do this, the alignment tabs 14 engaged with the gaps 3 of the governing bodies. The executive bodies are in curses 2, the reading gaps 13 of the reading comb 11 and the second plate 18 with each other. The first plates 17 are also aligned with the lamellae of the guide member 2 threads F held between the first platelets 17 in the reading gaps 13 thus become automatic read into the gaps 3. As soon as the engagement between the alignment projections shown in Figure 5 14 and the gaps 3 is made, the threads F are read and the reading comb 11 can be moved further in the direction A to a subsequent guide member 2. The process shown in FIG. 5 is repeated in the following guide member 2.

The transfer process is shown schematically in a side view in FIGS. 6a to 6c.

The guide members 2 are usually in the position shown in dashed lines in FIG. 6a. The guide members 2 lie in the path W formed for the threads F. According to the figure 6a, the guide members 2 are removed from the path W for the threads F.

The threads F are drawn through the device 1 in the direction A with the reading comb 11. The guide members 2 are designed to be lowerable and are lowered before the read-in process. Alternatively, it would also be conceivable to start up the guide members 2 or the guide members 2 and the reading comb 11 for reading the threads F into the guide members 2 lower or start up.

The reading comb 11 is pulled with the remaining threads R.

As soon as the reading comb 11 has passed the guide members 2 in direction A (see FIG. 6b), the movement of the reading comb 11 is temporarily interrupted. For this purpose, the reading comb 11 provided with holding elements 20, with a receiving device assigned to the guide member 2 4 can be engaged. The receiving device 4 allows a positioned Holding the reading comb 11. As soon as the reading comb 11 has reached position P. is, the guide members 2 are raised in direction B. The slats of the guide members 2 guided over the alignment projections 14 of the reading comb 11. To this An exact alignment of the gaps 3 with respect to the reading gaps 13 is ensured. When the guide members 2 are fully raised (see FIG. 6c), the threads F in the gaps 3 of the management bodies 2 and are thus read into the management bodies.

The reading comb 11 extends over the entire width of the device 1 the width 1.8 m to 2 m. It is also conceivable to use individual, smaller reading combs. The reading comb 11 is, for example, for holding 1,000 groups of 16 threads each educated. For this purpose, 1,000 second tiles 18 are provided, alternating with 1001 first Platelets 17 are arranged. The first and second plates 17, 18 typically exist made of steel and are manufactured or punched out, for example, by laser cutting. The The thickness d of the second plate 18 corresponds to the distance a between the first plate 17 and at the same time at least the thickness D between 2 elements of the guide members 2, that is the Width D of the gaps 3 (see Figure 8). The thickness of the first platelets 17 typically corresponds the thickness of the slats of the guide elements.

FIG. 8 shows in an enlarged representation how the threads F into the gaps 3 of the guide members 2 be handed over. The threads F lie on the support surface 19 through the second plate 18 is formed. The reading gaps 13, the second plate 18 and the gap 13 of the guide members 2 are aligned. This is ensured by the alignment projections 14 that intervene in the gaps 3. This ensures that the threads F are securely in the gaps 3 can be read.

The pin 23 prevents the threads F from jumping upwards from the reading gaps 13.

An alternative exemplary embodiment of a read-in comb 51 is shown schematically in FIG. The reading comb 51 is formed in one piece. There are gaps 53 in the reading comb 51 milled through which the threads F can be passed. On one side of the reading comb 51 are inserted into the reading gaps 53 projections 54 for aligning the Reading comb 51 serve based on the guide members 2.

Instead of individual alignment projections 14, 54, the reading comb 11, 51 with e.g. to align laterally arranged separate alignment elements on the guide elements 2. These alignment elements can for example laterally on the guide members and on be arranged the reading comb. It is also conceivable to insert the reading comb 11, 51 on guides to move through the device 1. Such guides can also laterally in the device be provided. Such guides allow a particularly stable movement of the reading comb 11, 51.
