Description

Technical field

The present invention relates to a guiding machine for automatically guiding warp yarns to leaf-braking elements of a mechanical state with a guiding device, means for handling leaf-braking elements, and a control stage for controlling the guiding machine.

BACKGROUND OF THE INVENTION

In a guiding machine of this kind known from US-A-3 681825, the individual functions are controlled by mechanical organs, such as eccentrics, control discs and the like, and are therefore self-bound together. Therefore, individual functional tasks cannot be performed separately and independently of other tasks, but a full cycle containing all functions always runs. As a result, erroneous operations of the individual function stages cannot be repeated and thus automatically corrected, but are either bearable and left, or must be removed manually when the machine is at a standstill.

If, for example, the separation heald is not properly separated, then the separation procedure cannot be repeated two or three times, since the guiding device always performs the appropriate number of guiding operations, and the beam would be removed by a suitable number of teeth. However, such separation errors occur more and more frequently in practice and therefore lead to a reduction in productivity also in the known guidance machines.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a warp yarn guiding machine which does not have the above disadvantage and in which it is thus possible to intervene in the course of the individual functional stages so that the other functional stages are not actuated.

SUMMARY OF THE INVENTION

This task is accomplished by a guiding machine for automatically guiding the warp threads to the leaf brake elements of a mechanical state with a guiding device, means for manipulating the leaf brake elements, and a control stage for controlling the guiding machine according to the invention. of the control module, from the programming module and at least one working module to carry out the guidance process, the individual modules form separate functional units connected to each other by interconnections, and the modules are connected to the master computer, whereby the intermediate computers run the transverse lines between the modules.

The control module constitutes a control stage and comprises a master computer, wherein the programming module is connected to the control module and is provided with a programming connection and a connection as a connection to the master computer.

Each working module has a module computer controlled and controlled by the master computer of the control module.

The guiding machine may comprise at least one of the following working modules: a yarn warp handling module and a warp thread layer, a warping module for a warping module, a heald module for heald manipulation, a warp stop module for manipulating a warp stop plate, a beam module for beam manipulation .

The working modules are divided into sub-modules into individual functions of the respective modules, an internal material flow controlled by the respective module computer is performed between the sub-modules, and a detection means is provided to detect material transfer between the sub-modules.

The machine further comprises an overall module for carrying out static auxiliary structures, in particular holding and fastening functions.

The overall module includes a connection for connection to the power supply of the homing machine and an adjustment of this energy.

The working modules have a feed and take-off connection, at the feed connection, the feeding of the leaf brake and the yarn is carried out and the guided leaf brake is removed at the removal side.

The control module is equipped with a service interface.

The programming module is equipped with a programming link and a connection to the master computer.

Accordingly, the solutions of the invention are individual functional stages formed by independent modules, each practically constituting a separate computer. Since these independent modules only communicate with each other via a master computer, there is no problem to let the module run isolated processes as needed, limited only to the module concerned, which have no effect on the other modules. Thus, for example, if the heald has not separated properly, the procedure may be repeated several times, with the computer remaining at this time so-called, and only working normally after a successful separation attempt. A further advantage of the solution according to the invention is that the modular assembly of the homing machine allows easy adaptation to the individual requirements of the customer.

BRIEF DESCRIPTION OF THE DRAWINGS

In the following, the invention will be explained in more detail by way of example with reference to the drawings, in which:

Fig. 1 shows a perspective overview of the guiding machine according to the invention, FIG. 2 is a functional diagram of the drawing machine of FIG. 1 and FIG. 3 shows a detail of FIG. Second

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, the guiding machine comprises a main stand 1 and various assemblies arranged therein, each representing a functional module. In front of the main stand 1, it is possible to distinguish a carriage 2 with a warp turret 3 disposed thereon. In addition, the warp trolley 2 comprises a lifting device 4 for attaching a frame 5 on which the warp threads KF are tensioned. This tensioning takes place before the actual guidance and at a location separate from the guidance machine, the frame 5 being located at the lower end of the hoisting device 4 in the immediate vicinity of the warp beacon 3. The guiding carriage 2 with the warping bait 3 and the hoisting device 4 arrives on the so-called supply side and the frame 5 in the lifting device 4 is lifted up and hung into the main stand 1, where it then assumes the position shown.

The frame 5 is movable in the longitudinal direction of the main stand 1 by means of a drive (not shown). In this displacement, the warp threads KF are guided around the separating group 6 and are separated and separated. After separation, the warp threads KF are cut off and presented to a guide needle 7 which forms part of the so-called guide module. Said partition group 6 is part of a so-called yarn module; it corresponds essentially to the warp thread separation device of the binding device described in EP-A-206 196.

Next to the guiding needle 7, a display unit 8 can be seen that belongs to the operator station and serves to display machine functions, machine malfunctions and input data. The operator station, which forms part of the so-called programming module, also contains an input stage for manual output of certain functions, such as pulling, start / stop, repetition of procedures, etc.

The guiding machine is controlled by a control module comprising a control computer which is located in the control box 9. This control box 9 comprises, beside the control computer, one module computer for each so-called main module, the individual module computers being controlled and controlled by the control computer. The main modules of the homing machine are next to the aforementioned modules: homing module, yarn module, control module and programming module. heald module, lamella module and beam module.

The splitting group 6, which presents the warp threads KF for guiding the guide needle 7, and the path of the guide needle movement 7, which extends vertically to the plane of the tensioned warp threads KF, define a plane in the region of the support 10 which is part of the main stand 1. the supply side and the so-called removal side of the homing machine lie to the right.

On the supply side, the warp threads KF and the individual elements to which the warp threads KF are guided are fed, and on the removal side, the so-called leaf block (healds, lamellas and beam) with warp yarn KF is taken. During guidance, both the warp yarn frame 5 and the warp bait carriage 3 move to the right around the divider group 6, the guiding needle 7 gradually withdrawing the warp yarn KF tensioned therefrom from the frame 5.

When all the warp threads KF have been guided and the frame 5 is empty, the frame 5, along with the carriage 2 and the warp spool 3, is located on the removal side and can be removed from the main stand 1.

Immediately behind the plane of the warp threads KF are warp stop plates LA, behind them the healds L1 and even further at the rear the beam WB. The slats LA are accumulated in the hand trays and the full hand trays are suspended on the inclined, arranged supply rails 11 on which they move to the right on the guide needle 7. There they are separated and brought to the guide position. After the guiding has been carried out, the slats LA reach the removal side on the support rails 12.

The healds L1 are aligned on the rails 13 and are moved manually or automatically to the separation step on them. Thereafter, the healds L1 are individually brought into their guidance positions and, after having been guided, divided into the corresponding heald blades 14 on the removal side. The beam WB also moves sequentially around the guide needle 7, opening the respective guide tooth. After guidance, the WB beam is also located on the removal side. A part of the beam WB can be seen on the right next to the heald blades 14. This illustration is purely illustrative for clarity, since the beam WB is of course on the removal side in the position shown of the frame 5.

As further shown in FIG. 1, a so-called leaf brake carriage 15 is disposed on the removal side. The carriage 15, together with the supporting rails 12 of the slats LA, the heald plates 14 and the beam holder WB, moves to the main stand 1 in the position shown and carries it. leaf bed 14 with guided warp threads KF. At this point, the warp trolley 2 is located immediately in front of the leaf brake carriage 14. Now, by means of the hoisting device 4, the leaf beam 14 is transferred from the trolley 15 onto the trolley 2, which then carries the warp beam 3 and guided leaf beam 14 and may go to the appropriate state or intermediate storage.

The mode of operation of the individual assemblies is not an object of the invention and therefore need not be further explained here. What is essential is that the activities are divided into several modules and that these modules are virtually independent computers that are controlled by a common control computer. The cross-links between the modules run through this master computer and there are no direct cross-links between the modules. When considering the structure of the described beacon machine, the beacon machine system receives beacon data or also data, control data, a boom and yarn, and energy and supplies the processed traffic data or data, status information and a guided leaf.

This assembly with system and module interconnections is shown schematically in FIG. 2. The guidance machine SE comprises a programming module PM, a control module SM, a so-called total AM module and at least one operating module XM, which may represent one of the aforementioned modules, yarn module, lamella module, heald module, beam module and guidance module. When more than one of these modules is available, the corresponding number of XM working modules must be arranged in parallel. In FIG. 2, three types of connections are indicated, where the solid line indicates a software connection, the dashed line indicates the hardware connection and the semicolon line the mechanical connection.

The PM programming module has a PRO programming link and a UER link to the host computer. The PRO programming link supplies PM programming data to the PM programming module and receives PM2 status information from it. The PM programming module supplies the processed PM3 operating data as well as the PM2 status information to the host computer via the UER link. In addition, there is a hardware link LA, consisting of a local area network (LAN), located between the PM programming module and the host computer.

The functions of the PM programming module are as follows, the program creation and machine operation menu, data communication with the control computer (SM), data management, processing of raw raw data taken from program creation, machine malfunction indication and communication with the master system.

The SM has a BED control interface to receive SM1 control data and to which it supplies SM2 status information. In the embodiment shown, the control module SM is also coupled to the programming module PM and the work module or work modules XM. The SM provides the SM3 raw operating data and the SM4 raw status information to the PM programming module, the SM5 module input data and the SM6 module commands to the XM.

The SM receives the modified PM4 input data and stabilized electricity from the PM programming module. In addition, an SM7 snap connection and an AT bus connection BU are located between the two PM and SM modules. The SM receives the XM3 module status data and the XM4 module questions from the work module (from each work module). Hardware connections between XM work module and

The control modules SM represent the emergency stop NS and the fieldbus FB.

As already mentioned, the SM includes a master control computer that controls and monitors the computers of each XM work module in real time processing. Each of the mentioned XM working modules contains one separate module computer. Tracking control functions are used to generate scanned data and for further routing to a master computer by UER connection.

The overall AM module serves to perform static auxiliary functions, especially in the hold and hold functions, and has two ELC and AIR interconnections to supply the SE machine with electrical and pneumatic energy. Electricity and air are processed by the total AM module and further transferred to the PM programming module (modified electricity only) and to the XM working module (modified electricity and conditioned air).

The XM work module is equipped with AUF feeder and ABR take-off. It receives the AUF feed link XM1 data of the leaf brake and the yarn and feeds the data of the XM2 of the guided leaf brake to the ABR pickup. In addition to these connections and the connections to the control module SM, there are three connections for the overall AM module: one attachment connection XM5 and two connections AM1 and AM2, which connect the XM working module for air or electricity.

As already mentioned, the XM working module is a replacement for one or more of the following yarn module, guide module, heald module, lamella module, beam module. These modules themselves are again divided into sub-modules, which are described below with their functions.

The yarn module takes over all the manipulation functions with the warp spool and the warp thread layer and includes the following sub-modules:

- Warp X handling: Transport along the machine and removal, allowing the yarn layer to be taken over by the other sub-modules, presenting the yarn layer and enabling removal.

- Yarn separation: separation of warp yarns and transfer to the presentation of the yarn.

- Presenting the yarn: Taking the yarns from the yarn separator, transporting the yarn ends to the guidance position and submitting to the guidance module, holding the yarn before and during the guidance in a defined state.

The guide module takes the threads from the presentation of the yarn and guides each thread through the lamella, heald and spoke. In addition, it is ensured that the guided yarn is removed from the guiding mechanism before the next guiding.

The heald module separates healds from the storage bundle to the guided heald on heald sheet 14 and consists of the following sub-modules:

- Creation of heaven heavens: Receiving healds by users, intermediate storage of healds, passing healds to another sub-module.

- Division of healds: This sub-module, which is used only when double healds come into the machine in a single bundle, is used to classify these healds into left and right healds.

- Separation of healds: Receiving the heald bundle, separating the healds from the bundle, passing each heald to the heald positioning sub module.

- heald positioning: receiving heald to heald separation module, heald transport to guide position, heald position laterally and vertically, heald transport with guided warp thread to the predetermined position of the heald shaft, passing heald to the appropriate heald shaft.

- Retaining the healds: During the guidance, the healds are held in order to allow the healds to be transferred from the healds to the healds, bringing the healds and the slats back and forth after guiding (associated with the warp warp handling sub-module), take-up procedure, enabling it to be played.

- Transport of healds: Transport of guided healds inside the healdsheets from the filling side to the other side, holding the healds rails also in the case of closed eyelets, allowing the feed and take-off procedure with the sub-module to hold the heald presses.

The lamella module removes the lamellae from the supply stack up to the guided lamellae on the support rail. It consists of the following sub-modules:

- Generating lamellar stock: Collecting lamellas by the user from the bundle, interim storage of lamellar bundles, passing lamellar bundles to another lamellar separation sub-module as needed.

- Separation of slats: Receiving slat bundles, separating each slat from the bundle, passing the slat to the slat separation sub module.

- Separation of the slats: Accepting the slat from the sub-module, separating the slats, transporting the slat to the guidance position, positioning the slat in the guidance position, transporting the slat with the thread guided to a certain position on the support rails.

- Transport of slats: Splitting the guided slats over the entire length of the support rails, retaining the support rails of the slats to allow passage of the slats and the entire length of the support rails;

The spoke module is designed to handle spokes and ensures that the guided threads no longer slide back. It consists of the following sub-modules.

Beam presentation: Movement of the beam to the desired position, presentation of the beam tooth in the guidance position, enabling guidance by the guidance module.

- Yarn fixing: Accepting the yarn from the guidance module, fixing the yarn after the guiding has taken place, continuing the transport of the guided yarn layer.

In FIG. 3 is one such operating module XM schematically shown. Analogously to FIG. 2, it is possible to recognize the supply-connection AUF and the take-off connection ABR, further the overall module AM and the control module SM and individual connections to these connections or modules. The illustrated working module has three (generally: n) TMI to TM3 sub-modules for performing the respective functions. The first sub-module TMI provides the leaf block or yarn XM1 elements, the last sub-blue 1 TM3 feeds the guided leaf block (SM2) to the ABR pick-up. All sub-modules are mechanically fastened (XM5) and are supplied ready in? spirit (AM1). There is an internal flow of material and detection between individual sub-modules, and there are internal attachments, as indicated by the connections between the sub-modules TMI and TM2 or TM2 and TM3.

As already mentioned, each XM work module contains one computer. This computer is shown in FIG. 3 is divided into two parts, namely the RE-HW hardware part and the RE-SW software part, wherein the RE-SW software part contains one SW1, SW2 or SW3 block for each TMI to TM3 sub-module. The hardware part of the RE-HW, which is provided with a power supply 16, consists of a microprocessor tag 17, an input / output tag 18, an excitation / adaptation stage 19, and an AT fieldbus. The hardware part of the RE-HW is supplied with the modified electricity (AM2) and supplies the signals 20 through the sensors of the individual sub-modules, processes these signals and sends the corresponding control signals to the sub-modules via the line 21.

The RE-SW software part contains, besides the blocks SW1, SW2 and SW3 assigned to the sub-modules, one additional hardware stage 22 and one communication stage 23. The hardware stage 22 is connected to the I / O tags 18 of the RE-HW hardware part via line 24 of control signals and line 25 sensor signals. Communication stage 23 sends status and polling data (XM3 / 4) to the control module SM and receives input data and commands (SM5 / 6) therefrom.

All working modules are assembled as described and are therefore replaceable. They can be adapted to the future needs of the market, ie refined and modified. Each module is an independent functional unit and the intelligence of the system is located in a decentralized manner. The system configuration can be completely customized to customer requirements. The independence of the modules allows for increased redundancy of the individual functions and allows for the individual choice of modules or functional units. The individual functions are interdependent only to a very small extent and errors can be easily localized.
