Abstract

The apparatus has several drive motors (e.g. 40, 41, 42) for moving the movable part subgroups (e.g. 35, 36, 37) and a controller, by which the drive motors can be controlled independently of each other. One of the subgroups (35) is coupled to one of the drive motors (40), and at least one more of them to another drive motor, so that the respective parts of the subgroups can be moved independently of the subgroups themselves. The control process is also described.

Description

  The present invention relates to a device for connecting a warp thread from a thread layer of a first warp thread to a warp thread from a thread layer of a second warp thread, the device comprising a plurality of movable parts and operating the movable parts A first warp thread and a second warp thread of the first warp thread, one of the warp thread of the first warp thread and one of the warp thread of the second warp thread, respectively, at the ends of these threads. It can be influenced by moving each of these parts in such a way that they are interconnected. The invention further relates to a method for connecting a warp thread from a thread layer of a first warp thread to a warp thread from a thread layer of a second warp thread by moving a plurality of moving parts.

  In many industrial processes based on the processing of threads (for example, methods of producing fabrics, textiles, etc.), a thread composed of a plurality of adjacently arranged, for example, parallel threads Layer handling plays a central role. For example, warp threads in warp yarns as processed on a loom are generally arranged more or less close to each other, thus forming an almost flat (warp) thread layer.

  Techniques for connecting threads from the first thread layer to threads from the second thread layer are used, inter alia, in connection with looms. For example, when weaving a warp thread using a loom, if one warp warp thread is processed according to length, the ends of the processed warp warp thread are joined to a new warp warp thread, It is customary to continue the weaving process with new warp.

  Many processes such as tying, winding, bonding, splicing, heat-sealing, etc. are used to connect the individual threads. These processes often require moving parts to affect the threads to be joined.

  Most recently, movable binding devices have been utilized to connect the warp yarns, these binding devices are inserted directly into the loom, and using a knot, one warp warp thread to another warp warp yarn Used to connect to a thread. The main components of such a binding device are (i) a movable frame (binding frame) for clamping two thread layers (warp threads), and (ii) two threads placed on that frame and An alternative tying machine that replaces individual threads in a layer.

Existing binding devices are designed to differ in detail, but operate according to substantially the same basic principles. The binding machine typically performs the following process steps to connect a thread in the first thread layer to a thread in the second thread layer. These processes are:
・ The machine on the binding frame moves forward (progress) toward the top (end) of one of the thread layers.
A process step that moves the second thread layer in such a way that the tops (ends) of the two thread layers overlap each other vertically; the foremost thread (positioned at the end) in the first thread layer And the process step of separating the foremost thread (located at the end) in the second thread layer, the process step of combining the two separated threads and cutting them A process step that connects two threads. A process step that removes the connected threads from the space occupied by the binding machine during forward movement.

  These process steps are typically repeated in successive cycles to connect all of the threads in the two thread layers.

  To perform each process step, typically many different parts are moved using a single drive, for example an electric motor or a crank handle. For this purpose, the main shaft is rotated using its drive and the rotation of the shaft is transmitted to the mechanical actuators involved in each process step, for example via gears and / or cam disks. Each of the movements of all the moving parts takes place (temporally and spatially) according to the instantaneous rotation angle of its main shaft according to a predetermined schedule (workflow).

  This concept is known from FR2190963 or DE2316625 or EP0206196A2, DE3543536C1, DE1970623C1 and has various disadvantages. First, each cycle of the aforementioned process steps must be carried out completely in accordance with each connection between its main shaft and the parts driven through the main shaft. This reduces the efficiency of the binding device.

  For example, one of those process steps may not be performed correctly during the cycle. The situation can occur, for example, when a thread has not been detached from the first and / or second thread layer at the start of a cycle. As a result, threads may not be supplied to the binding machine and cannot be connected to each other. Nevertheless, the cycle must be run through until the end, and thus further cycles or cycles, and all of the given process steps are between the desired seams between each thread. It must be repeated frequently enough until is made. As a result, errors in the execution of individual process steps result in a significant decrease in the operating speed of the binder (measured as the number of seams created between threads per unit time). A further disadvantage is seen in that when a thread with different characteristics is processed, the mechanical settings of the machine have to be changed mostly by manual intervention. A further disadvantage is seen in that the machine usually has to have a large number of moving parts in order to accurately control all (spatial and temporal) movements. A large number of related parts, such as cam disks, gears, and / or couplings between moving parts, for controlling their operating sequence, require high precision and as a result are usually expensive. End up.

French Patent No. 2190963 German Patent No. 2316625 European Patent No. 0206196 German Patent No. 3543536 German Patent No. 19706233

  The object of the present invention is to avoid the above disadvantages and to provide a seam between the end of the warp thread from one thread layer of the first warp and the end of the warp thread from the one thread layer of the second warp. It is an object of the present invention to provide a device and a method that can be generated with high efficiency and can simplify the control of the entire operation sequence.

  This object is achieved according to the invention by a device having the features of claim 1 and a process having the features of claim 8.

  In the following, the term “thread” will be used in place of the term “warp thread” as necessary (for the sake of simplicity), and “thread from the first thread layer” or “second thread layer”. The designation "thread from" is used instead of "warp thread from the first warp thread layer" or "thread from the second warp thread layer".

  The device according to the present invention has a plurality of movable parts, and each of the movable parts in such a manner that one warp thread of the first warp and one warp thread of the second warp are connected to each other at the ends of the threads. By operating each of these, the warp threads from the first warp thread layer and the warp threads from the second warp thread layer can be affected.

  According to the invention, the device has a plurality of drive motors for moving the movable parts, the partial number of movable parts being moved by one of the drive motors and at least one other part. An appropriate number of moving parts can be moved by a separate drive motor.

  The various drive motors can be operated independently of each other and can be controlled independently of each other using a controller.

  In addition, one partial number of parts is coupled to one drive motor, and each of the other partial numbers of parts is one partial number of each part of the other. A partial number is connected to each of the other drive motors in such a way as to be moved independently of each part. In this way, various partial numbers of parts can be moved independently of each other and their operation can be controlled independently of each other.

  Based on this concept, the number of moving parts required to implement each function of the device can be kept small. Compared to a conventional binding machine, in particular, mechanical components that control the operation sequence of other movable parts (for example, cam disks) can be omitted. The function of such mechanical components can be replaced each time by a drive motor combined with a controller that appropriately controls each drive motor. This replacement has several advantages. On the one hand, its mechanical components are usually expensive due to high demands on manufacturing tolerances, and on the other hand, relatively inexpensive drive motors can be used appropriately, so use multiple drive motors. Manufacturing costs can be saved. Furthermore, the control of the individual drive motors can be easily changed, for example, by changing the control program or by operating a specific control option that can be selected from a plurality of predetermined control options. This can be necessary or appropriate if, for example, yarns with different properties have to be processed and the function of the device can be optimized by a suitable control program. Thus, by using multiple drive motors, the operating sequence of different partial numbers of moving parts can be adapted to each other, or without changing or changing part of the structure of the device. It can be changed by affecting the control of the motor (by changing or adapting the control). In this way, the control of the device according to the present invention is simplified and more complex operation sequences are realized and selective by using relatively simple means (eg programming). Can be changed.

  Independent drive of multiple drive motors allows more flexible control of the device's operating sequence than devices with all moving parts connected to a single main shaft driven by a single drive motor Provides various possibilities.

  In a further embodiment of the device according to the invention, for example, the operation of the component in at least one partial number can be repeated independently of the component in each of the other partial numbers. Repeating the operation of the individual parts makes it possible, for example, to efficiently deal with inaccurately performed sequences and in some cases to eliminate errors efficiently. In the case of an error, it may be sufficient to repeat only the operation of the part associated with the incorrectly performed process step, regardless of the respective state of the other moving parts. This strategy allows for more efficient removal of errors and efficient and flexible process management, thus improving the operating speed of the device.

  In a further embodiment of the device according to the invention, the operation of the component in at least one partial number can be reversed independently of the component in the other partial number. This strategy also allows for more efficient error removal and efficient and flexible process management, thus improving the operating speed of the device.

  In each device design, the method for connecting a thread from the first thread layer to a thread from the second thread layer by moving a plurality of moving parts is usually considered an iterative process in a series of process steps, It can be taken into account that in each of these process steps, a partial number of moving parts specific to each process step can be moved.

  Thus, according to the present invention, a specific partial number of movable parts provided for one of the process steps is moved by at least one of the drive motors and provided for another of the process steps. It is appropriate to use at least two or more drive motors for moving the movable parts in such a way that a certain partial number of the movable parts given is moved by at least one of the other drive motors. Within this conceptual framework, for example, each of the drive motors for executing a plurality of process steps in each process can be used, for example, to execute a part of each process. However, it is also possible to assign one or more drive motors to each of these process steps, which are provided for performing each process step.

  Dividing the process into individual process steps, selecting the number of drive motors, and assigning each of the drive motors and process steps can be done arbitrarily depending on what is appropriate according to the circumstances of the individual case .

  In one variation of the invention, for example, the process steps in the process were separated from the first thread layer and the steps of separating the thread from the first thread layer and separating the thread from the second thread layer. Having at least two process steps of “making a seam between a thread and a thread separated from its second thread layer”, and at least two drive motors are available to perform the method , At least one of the drive motors is used to perform one process step (“separation of each thread”) and at least one other of the drive motors is used to perform another process step (“creating a seam between each thread”) ) To be used to perform

  A variant of the device according to the invention is used to carry out the process steps of the above-mentioned process, the first partial number of moving parts separating the warp threads from the thread layer of the first warp And / or having movable means for separating the warp threads from the thread layer of the second warp, one of these drive motors being provided for moving this partial number, and The second partial number of movable parts has movable means for creating a seam between the warp thread separated from the first warp thread layer and the warp thread separated from the second warp thread layer. One of these drive motors is then provided to move the movable means in this partial number. Accordingly, in this variation, it is possible to execute the process step “separate each thread” independently of the process step “create a seam between threads”. If the “separate” process step is performed incorrectly during operation of the device (eg, at least one of the threads to be separated will not be separated from each thread layer). The “separate thread” process step may be repeated initially (as frequently as necessary) before the “connect each thread” process step is executed. In this way, an improvement in the working efficiency and operating speed of the device is clearly realized.

  In a further development in the previous variant, the separation of the threads from the two thread layers is two process steps that can proceed independently of each other, and a dedicated drive motor is provided for each of the two process steps. In two process steps consisting of one process step "detach thread from first thread layer" and a further process step "detach thread from second thread layer" Is done. One of the drive motors is provided for driving a movable means for separating the thread from the first thread layer, and another drive motor is a movable means for separating the thread from the second thread layer. It is provided to drive. Accordingly, as in the previous variant, the further drive motor is movable means for creating a seam between the thread separated from the first thread layer and the thread separated from the second thread layer. It is provided to drive.

  If the separation of each thread is performed incorrectly during the operation of the device (for example, as a result, there are threads to be separated from the first thread layer and / or threads to be separated from the second thread layer) The process step “separate threads from the first thread layer” and / or the process step “separate threads from the second thread layer” is followed by the process of “connecting each thread”. It may be repeated alone or both together (as frequently as necessary) before the steps are performed. An improvement in the working efficiency and operating speed of the device is clearly realized by this means. Furthermore, in this variant, the fact that thread separation from the first thread layer and thread separation from the second thread layer are processes that can be performed independently of each other can be used. If only one of the threads to be detached during operation is detached but the other thread to be detached is not detached, repeat only the previously performed unsuccessful "detach" process step Just enough. On the other hand, the already separated thread may be held in a stationary position. In this way, the separation of the thread can be performed particularly gently, in particular so that unnecessary interaction between the moving part and the thread is avoided. This is advantageous when processing the thread layer of sensitive threads.

  In a further development of the foregoing embodiment, each process in these process steps may preferably have further process steps that may be performed independently of other process steps.

Each process in these process steps may include at least one of the following process steps a) to d), for example.
a) Holding and / or clamping the separated threads b) Cutting the separated threads c) Transporting the separated threads to a position where a seam is made between each of the separated threads d) Combined threads In order to carry out each of the additional process steps a) to d), one or more drive motors may be provided, which are exclusively engaged in carrying out the process steps a) to d). To do.

  Additional drive motors may be used to perform the following process steps. That is, at least one of the drive motors may be provided to position the thread layers relative to each other. Also, at least one of the additional drive motors may be provided to position the movable parts relative to each of the thread layers and thus to provide a progression of the movable parts relative to the thread layers.

  If a drive motor is provided for advancing the moving parts and is provided exclusively for this purpose, it is possible to carry out the progression independently of other process steps. This has several advantages. The progress depends on, for example, the state of each thread layer (for example, the thickness of each thread, the distance between the threads, the wear resistance of the threads, etc.) (by appropriately controlling the drive motor). It may be adapted individually in a simple manner, for example (in terms of distance and time or speed). Furthermore, the direction of travel may be reversed, in other words, the movable parts can be moved towards or away from each thread layer. In case of an error, regardless of the instantaneous position of the movable parts, all of the movable parts may be moved away from the thread layer (reverse movement).

  As shown in FIG. 2, the lower part 2 has a support frame 4 which is a means for supporting all the components of the device 1. Attached to the support frame 4 is a clamping frame 10 with two clamps 10.1 for threads in the thread layer 5 and a clamp with two clamps 11.1 for threads in the thread layer 6. Frame 11.

  In the clamping frame 10, the section of the warp thread in the first warp is held in the region of one end of the warp threads, which are shown only in the immediate vicinity of the clamping frame 10 ( The rest of the first warp is not shown.) Accordingly, in the tightening frame 11, the section of the warp thread in the second warp thread is held in the region of one end of the warp thread, which is shown only in the immediate vicinity of the tightening frame 11 in the figure. (The rest of the second warp is not shown.) The threads of the thread layer 5 are held by clamps 10.1 at two spatially separated arms in the clamping frame 10. Accordingly, the threads of the thread layer 6 are held by clamps 11.1 at two spatially separated arms in the clamping frame 11. The clamping frames 10 and 11 are arranged in the region between the two clamps 10.1 or between the two clamps 11.1, in such a way that each of the clamps 10.1 and 11.1 is spaced apart from each other. The upper part 3 is dimensioned in such a way that the upper part 3 is brought close to the thread layers 5 and 6 (FIGS. 1, 6 and 9).

  The clamping frames 10 and 11 are arranged parallel to each other so that the thread layers 5 and 6 are (substantially) aligned parallel to each other. Furthermore, it is assumed that the threads of the thread layer 5 are aligned parallel to each other in one plane.

On the other hand, the fastening frame 11 is a linear guide (not shown) in such a manner that the fastening frame 11 can move in parallel to the fastening frame 10 as shown by the double-headed arrow 12 in FIGS. Is mounted on the support frame 4. In this way, the thread of the thread layer 6 can be positioned relative to the thread of the thread layer 5.

  A rack 16 is attached to the support frame 4 via the support 15. A driveable worm gear 43.2 attached to the upper part 3 is used to engage the teeth of the rack 16 and to transmit force to the upper part 3 in the longitudinal direction of the rack 16 so that along the rack 16 The upper part 3 is moved.

According to FIGS. 1 and 3, the upper part 3 has a base frame 30 in which the following components are arranged, which are:
A drive motor 40 having separating means 35 for separating the threads of the thread layer 5 placed on the drive shaft, the separating means 35 being rotated around the (rotary) axis 40.1 of the drive motor 40 And a drive motor 40 configured in such a manner that it can be moved along the axis 40.1 (back and forth);

A drive motor 43 having a worm gear 43.2 placed on its drive shaft, the drive being configured in such a way that the worm gear 43.2 is rotated around a (rotation) shaft 43.1 of the drive motor 43 Motor 43;
A drive motor 44 having a worm gear 44.2 placed on its drive shaft, the drive being configured in such a way that the worm gear 44.2 is rotated about the (rotation) axis 44.1 of the drive motor 44 Motor 44;

  The drive motors 40, 41, 42, 43 and 44 are connected to the controller using the corresponding control signals via the respective connections 60.0, 60.1, 60.2, 60.3 and 60.4. 60 can be driven independently of each other.

  As shown in FIG. 3, in this case, the separating means 35 and 36 are designed as (conventional) separating needles, and the knotting means 37 is a knotting rod ("knot in the conventional hook").・ Also designed as “knot twister”.

A linear guide (not shown) for the upper part 3 is attached to the lower part 2 in such a way that it is moved parallel to the rack 16 and parallel to the thread layers 5 and 6. Guide 3 Axes 40.1, 41.1, 42.1, 43.1 and 44.1 or drive motors 40, 41, 42, 43 and 44 (as the upper part 3 is shown in FIGS. 1 and 2). To be placed on the lower part 2),
The worm gear 43.2 meshes with the teeth of the rack 16 (FIG. 2),
The worm gear 44.2 meshes with the teeth of the rack 21 (FIG. 2),
The shaft 40.1 is aligned parallel to the thread layer 5 and perpendicular to the thread of the thread layer 5, and one thread (thread 5.1 in FIG. 5) of the end of the thread layer 5 (of the drive motor 40) Approximately the same height as the thread layer 5 in such a way that the drive shaft is at a corresponding angular position and the upper portion 3 is properly positioned relative to the thread layer 5 and is captured using the separating means 35. Passing through (Figure 5),
The shaft 41.1 is aligned parallel to the thread layer 6 and perpendicular to the thread of the thread layer 6, and one thread (thread 6.1 in FIG. 5) of the end of the thread layer 6 is (of the drive motor 41). When the drive shaft is in a corresponding angular position and the upper part 3 is properly positioned with respect to the thread layer 6) in such a way that it is captured by the separating means 36, approximately at the same height as the thread layer 6. Street (Figure 5),

  When the worm gear 43.2 is rotated around the axis 43.1 with the help of the drive motor 43, this results in a linear movement of the upper part 3 in the longitudinal direction of the rack 16. The progression of the upper part 3 towards or away from the thread layer 5 depends on the respective direction of rotation of the worm gear 43.1 (using an appropriate control signal via the connection 60.3). May be brought under the control of the controller 60. In this way, the upper part 3 can be positioned relative to the thread layers 5 and 6.

  When the worm gear 44.2 is rotated around the axis 44.1 with the help of the drive motor 44, this leads to a linear movement of the rack 21 and the clamping frame 11 relative to the upper part 3 in the longitudinal direction of the rack 21. Bring. Progression toward or away from the upper part 3 of the clamping frame 11 depends on the respective direction of rotation of the worm gear 44.1 (using an appropriate control signal via the connection 60.4). May be brought under the control of the controller 60. In this way, the arrangement of the thread layer 6 with respect to the thread layer 5 can be changed.

  As a result, the distance between the thread layer 5 and the upper part 3 and the distance between the thread layer 6 and the upper part 3 may be changed independently of each other, or each may be a drive motor. It may be brought to a predetermined value by driving 43 and 44 appropriately.

  A method according to the invention for connecting threads from thread layer 5 to threads from thread layer 6 is described below with reference to FIGS. 1 and 3-11. A series of process steps (in this case 11 different process steps) are executed to connect one of the threads in the thread layer 5 and one of the threads in the thread layer 6.

  The process steps in each process are intended to separate the thread 5.1 at the end of the thread layer 5 and the thread 6.1 at the end of the thread layer 6 and connect them using a knot. Accordingly, all of the threads in thread layers 5 and 6 can be combined by periodically repeating the same series of process steps.

  In the first process step of the process, the upper part 3 is first brought into position with respect to the thread 5.1 of the thread layer 5. The upper part 3 is such that the thread 5.1 is within the range of the separating means 35 and can be separated in one of the subsequent process steps with the help of the separating means 35 by driving the drive motor 40. Positioned in a manner. The drive motor 43 is suitably controlled by the controller 60, and the worm wheel 43.2 is rotated to the corresponding rotation angle, and the instantaneous position of the upper part 3 relative to the thread layer 5 is determined by a sensor (not shown). .).

  In the second process step of the process, one sensor (not shown) determines whether the thread 6.1 has the same distance from the upper part 3 as the thread 5.1 within a predetermined tolerance. Used to check. Otherwise, the position of the thread layer 6 relative to the thread layer 5 is corrected as appropriate. For this purpose, the drive motor 44 is driven by the controller 60 and the worm wheel 44.2 is rotated to the corresponding rotation angle. This confirms that the thread 6.1 is within the range of the separating means 36, and that the thread 6.1 is separated in one of the subsequent process steps using the separating means 36 by driving the drive motor 41. It shall be

  In the third process step of the process, the separating means 35 is the working position for the thread 5.1, in other words, the position on the thread layer 5, from which the separating means 35 is connected to the thread 5.1 and the thread. It is brought to a position above the thread layer 5 where it can be introduced by rotation around the axis 40.1 into the intermediate region between the (adjacent) next threads in layer 5. The drive motor 40 is appropriately controlled by the controller 60 and the separating means 35 is moved along the axis 40.1 until the separating means 35 reaches a given working position and the shaft 40.1. Can be selectively rotated around. The schematics of FIGS. 1, 4 and 5 correspond to this situation.

  Accordingly, in the fourth process step of the process, the separating means 36 is in the working position for the thread 6.1, in other words, below the thread layer 6, from which the separating means 36 .1 and the intermediate region between the (adjacent) next thread in thread layer 6 is brought to a position below thread layer 6 where it can be introduced by rotation around axis 41.1. The drive motor 41 is appropriately controlled by the controller 60, and the separating means 36 is moved along the axis 41.1 until the separating means 36 reaches a given working position and the shaft 41.1. Can be selectively rotated around. The schematics of FIGS. 1, 4 and 5 correspond to this situation.

  In the fifth process step of the process, as shown in FIGS. 6, 7 and 8, the separating means 35 is caused to execute a “separating operation” for separating the thread 5.1 from the thread layer 5. The controller 60 first separates the drive motor 40 in such a way that the separating means 35 is introduced at least partly in the intermediate region between the thread 5.1 and the next thread (adjacent) in the thread layer 5. The means 35 is rotated around the axis 40.1 to a predetermined angle, after which the controller 60 is driven by the drive motor 40 from the remaining threads in the thread layer 5 in the direction of the arrow 40 ′ (FIGS. 7 and 8). The separating means 35 is moved so as to be separated by a distance. At this point, the separating means 35 is positioned at the test position. If the separating means 35 catches and pulls the thread 5.1 when performing the separating operation, then the thread 5.1 is transferred to the separating means 35 when the separating means 35 is positioned at its test position. In contact. In this case, the thread 5.1 has been successfully separated from the thread layer 5. In the situation shown in FIGS. 6-8, thread 5.1 is successfully separated.

  In the sixth process step of the process, the controller 60 checks (using a sensor not shown) whether one thread 5.1 was correctly separated as scheduled in the fifth process step. Otherwise (thus, if the thread is not separated, or if two or more threads are separated), the controller 60 will remove the test position from FIGS. 1, 4 and 5 from its test position according to FIGS. A command is given to the drive motor 40 to return the separating means 35 to the working position according to the above. The fifth and sixth process steps are then repeated sufficiently frequently until thread 5.1 is successfully separated in the fifth process step and moved to its test position (FIGS. 6-8).

  For thread 6.1, processing similar to the fifth and sixth process steps continues.

  In the seventh process step of the process, as shown in FIGS. 6 and 8, the separating means 36 is caused to execute a “separating operation” for separating the thread 6.1 from the thread layer 6. The controller 60 initially separates the drive motor 41 in such a way that the separation means 36 is introduced at least partially in the intermediate region between the thread 6.1 and the next thread (adjacent) in the thread layer 6. The means 36 is rotated around the axis 41.1 to a predetermined angle, after which the controller 60 is driven by the drive motor 41 by a predetermined distance from the remaining threads in the thread layer 6 in the direction of the arrow 41 ′ (FIG. 8). The separating means 36 is moved so as to leave. At this point, the separating means 36 is positioned at the test position. If the separating means 36 catches and pulls the thread 6.1 when performing the separating operation, then the thread 6.1 will be transferred to the separating means 36 when the separating means 36 is positioned in its test position. In contact. In this case, the thread 6.1 is successfully separated from the thread layer 6. In the situation shown in FIGS. 6-8, thread 6.1 is successfully separated.

  In the eighth process step of the process, the controller 60 checks (using a sensor not shown) whether one thread 6.1 was correctly separated as scheduled in the seventh process step. Otherwise, the controller 60 commands the drive motor 41 to return the separating means 36 from its test position according to FIGS. 6-8 to the working position according to FIGS. The seventh and eighth process steps are then repeated sufficiently frequently until thread 6.1 is successfully separated in the seventh process step and moved to its test position (FIGS. 6-8).

  Since the drive motors 40 and 41 can be operated and controlled independently of each other, the fifth and seventh process steps of the process may be performed at any point (independently of each other), for example, It may be executed simultaneously or continuously. Thus, the fifth or seventh process step of the process may be repeated as often as appropriate (independently of each other) until each of the threads 5.1 and 6.1 is separated.

  The process steps of each process are such that the total time of the process corresponds to a predetermined cycle time, and the total time of each process is a repetition of the fifth and sixth process steps, or the seventh and eighth processes. It can be controlled so as not to be lengthened by repetition of the step (provided that the total number of each repetition does not exceed a predetermined upper limit. When the total number of actual repetitions reaches or exceeds the predetermined upper limit, Longer cycle times can be predefined for all times.) After threads 5.1 and 6.1 are separated, they are connected to each other. This process is illustrated in FIGS.

  In the ninth process step of the process, the spatial arrangement of the separated threads 5.1 and 6.1 is changed in such a way that the threads 5.1 and 6.1 come into contact with the tying means 37. The For this purpose, the sleds 5.1 and 6.1 are driven by the drive motors 40 and 41 further in the direction of the arrows 40 ′ or 41 ′ and thus in the direction of the knotting means 37. Moved with help. Thereafter, the clamping device 50 with two movable arms 50.1 placed next to the knotting means 37 and controlled by the controller 60 is closed (by moving the arm 50.1), so that the thread 5 .1 and 6.1 are grouped between the arms 50.1 and pass behind the hook-shaped tying means 37 as shown in FIGS. 10 and 11 (FIGS. 9-11 are in a closed state). A clamp 50 is shown.) The separated sled 5.1 is then cut at the part between the separating means 35 and the clamp 10.1 on the clamping frame 10. For this purpose, a device 55 controlled by the controller 60 is provided for cutting (indicated symbolically by scissors in FIGS. 10 and 11). Accordingly, the separated thread 6.1 is then cut at the part between the separating means 36 and the clamp 11.1 on the clamping frame 11. For this purpose, a device 56 controlled by the controller 60 is provided for cutting (shown symbolically by scissors in FIGS. 10 and 11).

  In the tenth process step of the process, a seam is created between the thread 5.1 and thread 6.1 in the area of the thread's detached end. For this purpose, the drive motor 42 is driven by the controller 60 and thereby the knotting means 37 is rotated about the axis 42.1. At the same time, the separated ends of the threads 5.1 and 6.1 are captured by the hook-shaped ends of the knotting means 37 and are brought together to form a loop, the ends of the threads 5.1 and 6.1 being The knot is formed from the loop, and the knot is guided (by a conventional guide not shown in FIGS. 1-11) in such a way that the separated ends of the threads 5.1 and 6.1 are brought together.

  In the eleventh process step of the process, the combined ends of threads 5.1 and 6.1 cause the upper part 3 to be advanced in the direction of the thread layers 5 and 6, threads 5.1 and 6.1. Is further transported to a position where it does not interfere. Conventional transport means not shown in FIGS. 1 to 11 are provided for further transport of the threads 5.1 and 6.1.

  Finally, the series of process steps described above can be applied continuously to all other threads in thread layers 5 and 6.

  To drive the clamping device 50, the device 55 for cutting, the device 56 for cutting and the conveying means provided for further conveying of the threads 5.1 and 6.1 in the eleventh process step Multiple alternatives are provided within the framework of the present invention. In a variant, each of these devices or transport means may be fitted with its own drive motor that provides the respective movement of the moved part. The devices and transport means may also be connected to a common drive motor. The drive motor 42 may be used as this common drive motor, for example.

  The device 1 is designed as a tying machine. The concept according to the invention is likewise mobile to threads in the thread layer to be connected, for example winding, bonding, splicing, heat-sealing, etc. It can also be applied to other ways in which the part works. In these applications, only the tying means 37 of the device 1 need only be replaced by corresponding other means.
