Description

APPARATUS TO REMOVE A SINGLE HAIR / FIBER AT THE SAME TIME OF A BUNCH USING A GRIPPING DEVICE FIELD AND OBJECTIVES OF THE INVENTION The invention relates to an apparatus for removing a single hair / fiber at a time from a bundle using a grasping device. The object of the invention is to obtain an apparatus for removing a single hair / fiber at the same time from a bundle using a grasping device that allows the directed removal of a single hair / fiber at the same time of a bundle with a maximum precision - which means an error rate close to zero. If by chance the apparatus does not collect a single hair / bunch fiber, this must be considered respectively by the apparatus in accordance with a sub-object. The objective is reached when a first grip element has a wedge-shaped slot facing the second grip element and a second grip element has an essentially flat counter-pressure zone, further characterized in that the first grip element is conical in shape. the side of the wedge-shaped groove (cone A), whereby a hair / fiber individually removed from a bundle is fixed between the wedge-shaped groove and the counter-pressure zone. The invention is described in more detail by means of an illustrative embodiment.

DETAILED DESCRIPTION OF THE INVENTION Figures 1 to 16 show an apparatus 1 for removing a single hair / fiber 2 at a time from a bunch 3 using a gripping device 4, having a first and a second opposing gripping element 5, 6. The first element of grip 5 is connected to a first handle 21, and the second grip element 6 is connected to a second handle 22. The first and the second grip elements 5, 6 or the first handle 21 and the second handle 22 are relatively movable relative to each other or can be moved, for example, as if a pair of pliers were used. Optionally, both the first and the second gripping element 5, 6 can be arranged in a fixed location so that only one gripping element 5, 6 or only one handle 21, 22 can be moved precisely as appropriate by, for example, an automatically controlled hydraulic / pneumatic device (not shown). The first element The gripper 5 has a wedge-shaped groove 7 facing the second gripper 6, further characterized in that the second gripper 6 has an essentially flat counter-pressure zone 8, for retaining a single hair / fiber 2 which has been removed from a bundle 3 between the wedge-shaped groove 7 and the counter-pressure zone 8 when the first and second grip elements 5, 6 are pressed together (eg, Figure 10), and to pull said hair / bunch 3 fiber (automatically). Then the hair / fiber 2 is automatically fixed at both ends with a handle for an additional process, for example, with a prescribed length, to treat or test or examine it with a corresponding apparatus (not shown). The first gripping element 5 is conical on the side of the wedge-shaped groove 7 (cone A). The gripping element 5 is thus precisely routed upwards towards a first position of the multiple hairs / fibers 2 through a bunch 3 which is suspended in a fixed position and then collects, usually with the wedge-shaped groove 7, a single hair 2 or single fiber 2 (Figure 1 and 2). During the gripping process, there is a contact loaded with a spring between the first gripping member 5 and the second gripping member 6 using a spring device 37, disposed in a first or a second handle 21, 22 of the first or second element of grip 5, 6 and consists of a hole 38 with a lateral groove 39 (Figure 1). The wedge-shaped groove 7 has an edge width C of approximately 40 μm and an alpha angle of approximately 45 degrees (Figure 3). The cone A of the first gripping element 5 is formed by a cone with tip 31 (Figure 4). The slot 7 has at least the length D1 of the diameter of a hair / fiber. The average diameter of the hair is approximately 60 to 80 μm. The cone A of the first gripping element 5 is formed by a tip rectangular pyramid 32 (Figures 5 and 6), further characterized in that a pyramidal surface, in accordance with Figure 5, has an elongated rectangle and slot length D2 and, in accordance with Figure 6, a quadratic rectangle and slot length D3. Figure 7 shows the second gripping element 6 with a back pressure zone 8 arranged transverse to the length of the groove D1-3. Figure 8 shows a top view of the apparatus 1 according to Figure 2, but with a first and second handle 21, 22. Both gripping elements 5, 6 consist of a current conducting material (metal) and each is connected through a conductor 35, 36, wherein the first and second grip elements 5, 6 communicate with an electrical detection device 13 to control the collection of a single fiber / hair 2 of a bundle 3. The first and the second gripper element 5, 6 are formed as an electric current bridge 14 when they come into mechanical contact B (Figure 13) with one another, further characterized in that a current flow 15 indicates that there is no single hair / fiber 2 of a bunch 3 between the first and second grip elements 5, 6, and, respectively, another automatic process is possible. Figure 9 shows a top view of the apparatus 1 according to Figure 8, but in a first phase of the removal process for a single hair / fiber. Figure 10 shows an enlarged representation of the view according to Figure 9; Figure 1 1 shows another enlarged representation of the view in accordance with Figure 10, but in a phase of removal of a single hair / fiber 2 of a bunch 3.

Figure 12 shows the representation in accordance with Figure 11, but in an enlarged view and in a reduced perspective from above; Figure 13 shows a representation of compliance with Figure 9, but in an exceptional state of non-collection of the hair / fiber 2, which is detected by the detection device 13 (Figure 8). In accordance with figures 14 to 16, the first gripping element 5 is designed as a symmetrical rotation disc 9, further characterized in that the wedge-shaped groove 7 is designed as a groove of the peripheral ring 10 with a bevel 33 on each side (figures 15 and 16) as the cone A. The second grip element 6 is a cylindrical disk 11, further characterized in that the groove of the peripheral ring 10 and a surface 12 of the cylindrical disk 11 communicate with each other. The symmetrical rotation disk 9 consists of two similar sheets of symmetrical rotation 34, whereby a groove of the ring 10 with a width of the edge C of approx. 40 μm Reference list 1 device 2 hair / fiber 3 bunch 4 gripper 5 first gripper 6 second gripper 7 slot 8 counter-pressure area 9 symmetric rotation disc 10 ring groove 11 cylindrical disk 12 surface 13 detection device 14 current bridge 15 current flow 21 first handle 22 second handle 31 cone with tip 32 tip of pyramid 33 bezel 34 half disc 35, 36 conductor 37 spring device 38 perforation 39 slot A cone B mechanical contact C edge width / groove 7 D1 -3 slot length alpha angle / slot 7 SUMMARY An apparatus (1) for removing a single hair / fiber (2) at a time from a bundle (3) using a grasping device (4), having a first and a second opposing grip element (5,6).
