Definitions
- the invention relates, according to the preamble of independent claim 1, to a device for tensioning warp threads on a warp threading machine, with a frame for tensioned warp threads arranged essentially vertically and next to a thread severing device for severing the warp threads, the thread severing device in a first edge region of the frame is arranged in a stationary manner and the frame is guided in the first edge region in a direction transverse to a plane formed by the stretched warp threads and is slidably connected to the thread separating device in one direction and the frame is movably mounted in a second edge region and for displacement in one Direction as well as across and parallel to the plane.
- a disadvantage of this known device can be seen in particular in the fact that both the thread cutting device and the frame are mounted on the base frame and their position relative to one another is defined by the position relative to the base frame. That means that ultimately the location of the Level of the stretched warp threads as well as the position of the thread separating device is ensured by guides and support elements which are attached to the base frame. Such guides and support elements are sometimes long, deformable and have play.
- the position of the thread cutting device in front of the warp threads is only accurate with restrictions. This means that the more precise the position, the stiffer and heavier the supports and guides mentioned.
- the invention as characterized in the claims, therefore solves the problem of creating a simple and light device of the type mentioned, in which the warp threads to be separated and the thread separating device lie as precisely as possible with respect to one another.
- the frame is mounted in a mobile manner in an edge area and is guided for displacement in one direction and in a further edge area it is displaceable and directly connected to the thread cutting device in the same direction is.
- the frame is preferably guided at at least three objectionable points that lie in the corners of a triangle, specifically at two points. len against gravity and lateral displacement in one direction and at least in one place only against lateral displacement in one direction. This last position is always at or in the immediate vicinity of the thread cutting element or the thread cutting device. This also applies to another possible position for guiding against lateral displacement.
- Preferred developments of the device according to the invention result from the dependent claims.
- the advantages achieved by the invention can be seen in particular in the fact that the warp thread to be separated always comes to lie exactly in the right place in front of the thread separating device. This is irrespective of whether a base frame is locally deformed by the weight of the frame or whether the frame is distorted. On the one hand, the removal of the warp thread can be carried out safely and with a device that is not particularly heavy and stiff.
- Figure 1 is a perspective view of the device
- Figure 2 shows a section through the device
- the frame 1 shows a device according to the invention with a frame 1 for tensioning warp threads, which are not shown here.
- the frame 1 consists essentially of two horizontal supports 2, 3 and two vertical supports 4, 5.
- guide rails 6, 7 for the warp threads, so that these are next to one another lie in a surface or plane.
- On the upper horizontal support 2 a further guide rail 8 is also attached, which for guiding the Frame 1 is used.
- Two rollers 9, 10 are movably supported on the lower horizontal support 3 or possibly also on the supports 4, 5. These run and are supported on a stationary rail 11.
- a thread cutting device 13 is mounted in a stationary manner next to the frame 1.
- the thread cutting device 13 has on the housing 14 as guide rollers a pair of rollers 15 in which the rail 8 can pass.
- the rollers 9, 10 already mentioned are arranged, which support the frame 1 in a mobile manner.
- a further roller 19 is likewise mounted in a stationary manner, on which a clamping rail 27, which is only partially shown here, is supported laterally.
- Further devices such as a brush tree 17 for tensioning the warp threads, etc., are attached to the frame 1.
- a brush tree 17 for tensioning the warp threads, etc. are attached to the frame 1.
- such devices are known per se and are not important for the present invention.
- FIG. 2 again shows the same elements as FIG. 1, which are therefore also provided with the same reference symbols. However, these are not mentioned again individually here.
- the housing 14 of the thread cutting device 13 is only partially shown. For this it can be seen better here that the rail 8 is guided in the pair of rollers 15 or between the rollers 15. Here, however, a warp thread family 18 is shown, which is positioned by the guide rail 6, 7.
- the mode of operation of the device according to the invention is as follows:
- a warp thread sheet 18 is stretched in front of the guide rails 6, 7, for example further stretched by the brush tree 17 and by rails, as the clamping rail 27 (Fig. 2) attached, ie clamped on the guide rail 6, 7.
- the frame 1 can be brought into a position by displacement on the rail 11, in which the pair of rollers 15 lies at one end of the rail 8.
- the clamping rail 27 rests on the roller 19 at the bottom.
- the warp thread sheet 18 spans a surface or plane 20 which is parallel to the main axes 21, 22 of the rails 8 and 11.
- the frame 1 is moved in the direction of the main axes 21, 22. It is guided in the edge region 16 by the rollers 9, 10 on the rail 11 against displacements transverse to the rail 11 or its main axis 22 in two directions according to arrows 23, 24.
- the frame 1 is guided by the fixed pair of rollers 15 and the rail 8 only against displacements in the direction of the arrow 23.
- the frame 1 is additionally guided in the direction of arrow 23 by the fixed roller 19.
- the frame 1 is pressed against the roller 19 by its own weight.
- the rollers 9, 10 are preferably pivotally or tiltably connected to the frame via joints 30. These joints are preferably arranged on the side of the center of gravity of the frame facing the thread separating member, so that the frame 1 with the resulting, essentially horizontal component of its own weight rests securely on the roller 19.
- the frame 1 is supported or guided at least at three points A, B, C and optionally additionally at one point D.
- the frame is guided along the main axis 22.
- the frame is guided in the direction of arrow 23.
- the warp thread sheet 18 has a constant distance 25 in the vicinity of the thread cutting device 13, which is given here, for example, between the warp thread sheet 18 and an outer boundary 26 of the housing 14, but in reality to a separating element which is not shown here but is known per se is guaranteed.
- the warp threads are separated for separation even when, for example, the rail 8 is bent.
- the pair of rollers 15 could also absorb gravity with a suitable design, so that the frame 1 would then be at least partially attached to the thread cutting device 13.
- the roller 19 together with the clamping rail 27 guides the frame 1 particularly precisely when the roller 9, 10 on the rail 11, in particular also because of the pivotable or tiltable connection of the rollers 9, 10 to the frame 1, no precise guidance in the direction of arrow 23 can guarantee, or if the frame 1 allows certain deformations.
