Definitions
- the invention relates to a control for the electric motor of a device for forming a leno edge on a weaving machine with heald frames according to the preamble of claims 1 and 2.
- a device for forming a leno edge is known for example from DE 44 05 776 C1.
- an electrically controllable servomotor is provided which drives a rotating disk, the rotating disk forming the rotor of the electrically controllable servomotor.
- the rotating disc itself has at least two guide elements for the leno threads, the leno edge being formed by twisting the leno threads around the weft thread.
- a device for forming a leno edge is known, the rotor of an electric motor having arms for guiding leno threads.
- the leno edge is formed by twisting the leno threads passed through the arms around the weft thread.
- the control of the leno edge device is dependent on the heald frame; rather, the control and correspondingly the rotational movement of the rotor of the electric motor of the leno selvedge device are independent of the heald frame, because a direct mechanical coupling between the heald frames and leno selvedge device is not provided.
- the leno selvedge device is coupled to the weaving machine insofar as the movement of the leno selvedge device, that is to say the rotor of the electric motor, runs synchronously with the movement of the drive shaft of the weaving machine or correspondingly with the movement of the heald frames.
- the invention is therefore based on the object of providing a control of the type mentioned at the outset, with which the electric motor of a device for forming a leno edge can be controlled in such a way that the setting takes place independently of the movement of the heald frames, but nevertheless in the period between and shed locking.
- the object is accordingly achieved in that the control of the electric motor is supplied with a start pulse at the time at which the weaving machine starts the opening of the compartment or the beginning of the closing of the compartment.
- Another variant for solving the problem is to make the control of the electric motor dependent on the weft thread entry.
- the control of the electric motor is supplied with a start pulse at the point in time at which the insertion of the weft thread begins or the weft entry is ended. In both cases, however, the speed of rotation of the rotor of the electric motor for opening and closing the compartment is higher than the speed of the heald frames for opening and closing the compartment.
- FIG. 1 shows schematically the device according to the invention in relation to its position in relation to the tissue, the stems and the reed being omitted because of the better overview;
- Figure 2 shows a schematic representation of the course of the path of the heald frames or rotation of the rotor of the electric motor of the leno device over time.
- an electric motor generally designated 10
- two pairs of arms 60, 70 are provided in the illustrated embodiment, in which the axis of rotation is transverse to the warp threads 40, i.e. H. runs essentially parallel to the weft threads 50.
- the device works with only one pair of arms 60, which is arranged on the fabric side of the rotor of the electric motor. These pairs of arms are designed similarly to propeller blades and are arranged on the rotor. Every pair of arms
- 60, 70 consists of two arms 61, 62 and 71, 72 designed like a propeller blade, respectively.
- the two pairs of arms 60, 70 run parallel to one another and are fastened to the respective front end of the rotor of the electric motor 10, as can be clearly seen from FIG .
- 61, 62 and 71, 72 are bent in the shape of a hook at the end and have the eyelets 73, 74 and 63, 64 in the region of the hook-shaped bend. These eyelets serve to pass the leno threads 20, 30, which are drawn off from the bobbins 80, 90.
- the arm pairs 60, 70 and here in particular the arm pair 60 rotate, the full-turn edge 100 is created in the area of the fabric. In the area of the feed of the Twisting of the threads (at 1 10), which is canceled again by reversing the direction of rotation of the rotor in one direction after a certain number of revolutions. This means that the rotor of the electric motor runs forwards and backwards. Untwisting of the leno edge 100 is avoided in that the weft threads 50 lie between the leno threads.
- FIG. 2 shows the sequence of movements on the one hand of the heald frames over time, and on the other hand of the rotor of the electric motor of the leno selvedge device also over time. From this it can be seen that by the time the heald frames are finally open, the rotor is already holding the leno threads in the open position. It also follows from the course of the curve that the rotor of the electric motor is able to keep the compartment open much longer than the heald frames.
- the device according to the invention can work with a smaller compartment and, which is also essential, can be mounted particularly far forward, namely between the shafts directly on the reed. By keeping the compartment open for such a long time, the special requirements of rapier weaving machines are taken into account insofar as the period for the rapier to remain in the compartment becomes longer.
- control is much easier to accomplish, since significantly fewer control signals have to be processed, because no electrical shaft or electrical cam plate has to be simulated with a lot of control technology. This means that such a control is also much cheaper to manufacture. It also shows that such a control is less susceptible. In addition, this type of control is very useful for the use of simple and therefore inexpensive stepper motors.
