Definitions
- the invention relates to a rotary edge turner for weaving machines, by means of which the weft threads are tied at the fabric edges by means of a leno binding.
- the drive of the edge turner arranged on both sides of the weaving machine next to the edge warp threads takes place in such a way that the rotary disc forming the actual edge rotator is connected to a drive wheel in a rotationally driven connection via a toothed belt.
- the drive wheel is non-rotatably connected to and driven by a gear-driven countershaft.
- the countershaft is in turn connected to the main drive of the weaving machine by a toothed belt.
- the countershaft is connected to a hollow shaft protruding in the direction of the weaving width adjustment, in which a shaft part which drives the second rotator disk and the drive of the second rotator bobbin holder can be displaced.
- a shaft part which drives the second rotator disk and the drive of the second rotator bobbin holder can be displaced.
- the rotating disc has external teeth. Furthermore, the rotating disc is rotatably mounted in a bezel-like manner. The leno threads are drawn off from a bobbin winder, which is rotationally driven and operatively connected to the rotating disc, and fed to a guide opening located centrally in the rotating disc.
- the rotating disc also has two diametrically opposed eyelets in the rotating disc, through which the thread is guided to the weaving point of the fabric.
- the external toothing of the rotating disc is in engagement with the teeth of a drive gear which drives the rotating coil holder in synchronism with the rotating disc.
- edge turner In contrast to the prior art, the edge turner should not be separated from the weaving machine for the purpose of changing the article, and the edge turner should be readily adaptable to different weaving widths. This is intended to achieve considerable savings in makeready times in the weaving mills.
- Another object of the invention is to dispense with a separate drive for the holder (carousel) receiving the leno thread bobbins.
- a separate drive for the holder (carousel) receiving the leno thread bobbins According to the prior art, such a drive is intended to prevent the leno threads from looping around one another in the area of the back pocket. In order to avoid thread breaks, the leno threads must be fed to the rotating disc without twisting.
- the rotary edge turner should also have a simple construction and be driven directly, ie without the inclusion of a transmission means between the servomotor and the rotating disc.
- the object is achieved by the features of claim 1.
- the electromotive actuator it is now possible for the first time to control the sequence of movements of the individual edge twists independently of one another and independently of the weaving machine drive. It is conceivable, for example, that the setting of the weft threads can take place depending on the type of the weft thread and that the setting of the weft thread on the side of the weft thread insertion can be before the setting of the weft thread on the weft thread arrival side.
- a controlled reversal of the direction of rotation of the rotating disc which ultimately also includes an oscillating reversal of the direction of rotation, means that there is no need to drive the rotating bobbin holder, because in any case the twists or loops of the leno threads on the way between the rotating bobbins and the rotating disc, caused by a specific one Number of right turns of the rotator disc can be canceled by the same number of left turns of the same rotator disc.
- This edge turner can advantageously be positioned as close as possible to the weaving point of the fabric and between the frame and the healds of the first heald frames.
- the number of usable heald frames in the direction of the warp beam, ie opposite to the weaving direction, is thus not limited.
- edge turner Due to the compact design of the edge turner, it is possible to position the edge turner quickly to the changed conditions of the weaving machine in the event of an article change or a weaving width adjustment.
- Another advantage of the invention is that additional means which drive the rotating disc, such as e.g. a drive gear connected to the servomotor and a toothed belt transmitting the motor rotary drive to the rotator disc, between the servomotor and the rotator disc are eliminated.
- the rotary edge rotator 1 consists of a disk-like, electrically controllable servomotor 2 with a stator 3 and a rotor, which forms the rotating disk 4 with two passages 4a and 4b arranged symmetrically about the central axis 5 of the rotating disk 4.
- the passages are preferably designed in the form of a circular arc.
- a leno thread 6, 7 supplied by rotator bobbins, not shown, is passed through each passage 4a, 4b. Both leno threads 6, 7 form a front leno thread pocket 8 that is adequate for the shed (front pocket) by turning the rotating disc 4.
- the leno threads 6, 7 are brought together in the binding point 9 of the fabric 10. In the binding point 9, the ends of the respective weft thread 11 are tied by at least half a turn of the rotating disc 4 in the direction of arrow 12 or in the direction of arrow 13 to form a fixed fabric edge.
- the inside of the stator 3, together with an annular carrier part 14, forms a circumferential U-shaped groove in which the rotating disk 4 is received in a rotating manner.
- the servomotor 2 is a motor of known operating principle, the stator 3 carrying the windings and the rotor or the rotator disk 4 receiving magnets 15 arranged distributed on the outer circumference.
- the rotating disc 4 is preferably designed to save mass, namely as a ring.
- the annular carrier part 14 forms a holder 16 which is connected to a hub 18 by means of connecting elements 17.
- the hub 18 can also be connected in a rotationally fixed manner to a component 20 via a connecting element 19.
- the component 20 is firmly connected to a component 21 that can be adjusted to the weaving width of the weaving machine.
- the edge-turning device shown here is an edge-turning device arranged on the left-hand side of the weaving machine, another edge-turning device is arranged on the right-hand weaving machine side. Both rotary edge rotators are arranged in the area of the free space between the shaft frame, not shown here, and strands of the first heald frames, which are behind the reed not shown and are not shown.
- an electrically controllable servomotor 2 as a direct drive for the rotating disc 4 of the rotary edge rotator 1 allows the weaving machine manufacturer to dispense with a separate rotary drive for the leno thread bobbins, because e.g. by programming a number of rotations of the servomotor 2 and thus by a fixed number of revolutions of the rotary disc 4 in one direction and by the same number of revolutions in the opposite direction, a looping of the leno threads 6, 7 supplied by the rotator bobbins in the area of the rear compartment does not more occurs.
- a servomotor 2 as a drive for the rotating disk 4 also allows the direction of rotation of the rotating disk 4 weft 11 for weft 11 to be driven in an oscillating manner. In this case, too, a separate drive for the rotating coils is not necessary.
