Definitions
- the invention relates to a weaving machine, in particular a ribbon loom, with a shedding device having a shank device and a shaft frame, according to the preamble of claim 1. Furthermore, the invention relates to a corresponding weaving method.
- Shedding apparatuses for looms comprising a shank device and a shaft frame are basically known from numerous documents.
- a weaving machine is known, in which for example a shaft frame having driving part is clamped for driving the warp threads of a loom between two springs. There, the driving part swings and a holding device is able to stop the vibration for a certain duration and so form a shed during the weft insertion.
- This shedding device was further developed in WO 2008/037 106 A1. Such shedding devices have proven to be quite advantageous, in particular for operation at high speeds, ie with high weaving speed, in particular for limiting the energy required.
- the object of the invention is to flexibly influence the weft insertion in a shuttle loom by means coupled to the shafts means.
- Examples are a weft color changing device or a device for producing differently sized weft loops at the strip edges at regular or irregular intervals.
- the object is - solved according to a first aspect - by a shuttle loom according to claim 1.
- the measures of the invention initially have an unexpectedly high level of flexibility. Characterized in that the control device for driving the linear motors is designed so that the driving of a predetermined position of the shaft frame between the upper maximum position and the lower maximum position is made possible at a given time, each shaft frame differently than eg in WO 2008/037106 A1 much be used more flexible. For example, to increase the weaving speed, it is possible to make the tray smaller, that is, to make the difference between the high and low shots smaller than the maximum difference.
- the control is basically able to "fully" train the subject very quickly and then leave it at best for a certain period of time.
- the weft insertion device is more likely to enter the shot - preferably by means of a weft needle, alternatively also by means of a gripper device or a pneumatic - enter.
- a gripper device or a pneumatic - enter.
- the "middle specializations" do not all have to be the same, but rather - programmable - can differ from one another, for example, depending on whether they are taken from the upper subject position or the lower subject position.
- the controller is designed so that it essentially corresponds to the time point of the shaft frame movement controls, preferably in each case the beginning of the movement. This is particularly advantageous when the linear motors require the highest power consumption at the beginning of the movement, because thus the time points of the beginning of the movement can be decoupled and at least not all linear motors simultaneously request the highest power consumption.
- the weft insertion device has a multiplicity of positively driven weft feeders with which a predetermined amount of the corresponding weft thread can be fed, if the assigned color control means is selected for insertion of the weft thread.
- Control device preferably by means of a PID controller, by means of which a current desired position is determined for moving the respective shaft frame the difference between the instantaneous actual position and the current setpoint position of the respective shaft frame of the shaft device can then be regulated.
- the closed-loop control device is preferably set up such that the following error can essentially be made to disappear at the specified time, that is to say at the predetermined position, with the result that the predetermined position is reached at the given time.
- FIG. 1 shows a basic structure of an application of the present invention with a weft insertion device, wherein each one of the
- Color control means is associated with a shaft frame and the selective entry of the corresponding weft thread by the movement of said shaft frame is controllable;
- FIG. 2 shows the movement curves of the weaving elements according to the application according to FIG. 1 in a case that the first weft color is introduced into the compartment and the second weft color is woven into the selvedge;
- Figure 3 shows the movement curves of the weaving elements according to the application according to Figure 1 in a color change case, the first shot color read and the second shot color is read;
- FIG. 4a shows the entry of the first shot color
- Figure 4b shows the state shortly before the reading of the second shot color
- Figure 4c shows the weft needle at its left turning point
- FIG. 4d shows the weft needle just before it re-enters the shed
- FIG. 4e shows the entry of the second shot color. Ways to carry out the invention
- FIG. 1 shows a particularly advantageous embodiment of the present invention.
- Figure 1 shows the essential elements of a shuttle loom with a weft insertion device, each one of the color control means, in the illustrated embodiment the Fadenvorlege issued 18 for the first color and 20 for the second color a shaft frame 4 and 6 are assigned and the selective entry of the corresponding weft yarn Movement of said shaft frame 4, 6 can be controlled.
- the Fadenvorlege issued 18 for the first color and 20 for the second color a shaft frame 4 and 6 are assigned and the selective entry of the corresponding weft yarn Movement of said shaft frame 4, 6 can be controlled.
- Shaft frames 8 and 10 are conventionally assigned to the design of the shed.
- the other elements of the shuttle loom namely the reed 28 and the tarred Webgut 26 and the warp threads in the high-bay 22 and the warp threads in the Tieffach 24 are here representative of the other conventional elements of a known shuttle loom.
- the weaving machine comprises a control device for controlling the linear motors for the shafts, which is designed so that the driving of a predetermined position of the shaft frame between the upper maximum position and the lower maximum position is made possible at a given time.
- the shuttle loom comprises a sensor device by means of which the position of each of the shaft frames 4, 6, 8, 10 can be continuously determined.
- the weft insertion device is further associated with a plurality of positively driven weft supply means 30, 32, with which a predetermined amount of the corresponding weft yarn 40, 42 can be fed, when the associated color control means 18, 20 is selected for registering the weft thread 40, 42.
- the control device has a control device by means of a PID controller, by means of the movement of the respective shaft frame 4, 6, 8, 10 a current target position is determined and the following error, ie the difference of the current actual position to the current target position of the respective shaft frame the shaft device is regulated.
- the control device is set up in the present embodiment, that the following error to the mentioned Time, that is at the predetermined position is essentially made to disappear.
- FIG. 2 shows the phase sequence, namely the movement curves of the weaving elements as a function of the angle of rotation (phase angle) of the main shaft according to the application according to FIG. 1 in a case where the first weft color is entered into the shed 22, 24 and the second weft color is inserted into the selvage of the web Woven good 26 is woven.
- the essential phase times namely the phase point A "blade stop", the phase point B "weft needle entry into the shed" are shown in the diagram.
- FIG. 3 shows the phase sequence, namely the movement curves of the weaving elements as a function of the angle of rotation (phase angle) of the main shaft according to the application according to FIG. 1 in a case that the weft thread of the first weft color is read in and the weft thread of the second weft color is read out.
- the essential phase times namely the phase point A "sheet stop", the phase point B "weft needle entry into the shed", the phase time point C “reading the weft of the first shot color” and phase time point D "reading the weft of the second shot color” in the diagram.
- FIG. 4a shows the entry of the first
- FIG. 4b shows the state shortly before the picking of the weft thread 42 of the second weft color.
- the weft needle 14 moves out of the compartment.
- the color control needle 20 of the second color is brought into its upper position, the weft thread 42 of the second shot color touches the weft needle 14 from below and at the next moment in the opening at the top of

- the weft threads of both weft colors 40, 42 are in the opening at the tip of the weft needle 14.
- Figure 4d shows the weft needle 14 just before re-entry into the shed.
- the color control needle 18 of the first shot color is brought into its lower position, the weft thread 40 of the first shot color thereby jumps out of the opening at the tip of the weft needle 14.
- the weft yarn 42 of the second weft color remains in the opening at the tip of the weft needle 14 because the associated color control needle 20 remains in its upper position.
- FIG. 4e shows the entry of the weft thread 42 of the second weft color.
- the weft 42 is taken through the opening at the tip of the weft needle 14.
- the weft thread 40 of the first weft color is not taken along by the weft needle 14, but remains in the region of the left edge of the tape.
