In an embodiment that is not shown, the pressing part has a guiding part into which the pressing part can be pushed. Here, the displacement path extends the farthest from the normal position to the pressing position. The attachment part 140 and the pressing part 150 cannot be displaced further away from each other or further displaced toward each other after reaching these two final positions, and are mutually displaced along the entire displacement path (including these two positions). Keep it together. The compression spring arranged in the guide portion is compressed when the storage bin attachment 130 is pressed onto the base and ensures that when the storage bin attachment 130 is lifted away from the base, the attachment portion 140 and the pressing portion 150 Shift to the normal position. In addition, the storage accessory 130 includes a transport mechanism (not shown in detail) for transporting the fastening element strip 100 carrying the fastening element 115 in the transport direction 105, wherein, for example, by pressing the storage accessory 130 to The transport mechanism is manipulated on the base and/or by lifting the bin attachment 130 away from the base.

The fastening element strip 100 has a plurality of accommodating parts arranged one after another in the transport direction, in which fastening elements 115 are respectively accommodated. The bin attachment 130 (especially the pressing portion 150) includes a separating device 200 for separating the fastening element 115 from the fastening element strip 100 accordingly. The separating device 200 includes a transport channel 210 having an inlet port 220 and an outlet port 230, which is used to transport the fastening element strip 100 in a transport direction 105 from the inlet port 220 to the outlet port in a guided manner. Port 230, in which the outer side of the transportation channel 210 can be seen in FIG. 1. The separating device 200 has a passage for driving an element that separates the fastening element from the fastening element strip in the separating direction and comes out of the receiving part to be driven into the base. Therefore, the driving element forms a separating element so that the separating direction and the fastening direction defined by the fastening element 115 coincide. The fastening element 115 has, for example, a rod portion with a longitudinal direction that defines the fastening direction. In particular, the fastening element 115 has a head at one end and/or a tip at the opposite end. In an embodiment not shown, the separation direction and the fastening direction are offset from each other and are oriented perpendicular to each other, for example.

Figures 2 and 3 each separately show the first half-shell 240 (Figure 2) and the second half-shell 250 (Figure 3). The first half-shell and the second half-shell combined form a transportation channel 210. In the figure The inner side of the transportation channel can be seen in 2 and 3. The transport channel 210 has a separation section 260 between the inlet port 220 and the outlet port 230 in which the fastening element 115 is separated from the fastening element strip 100 in the separation direction 265. In addition, the transportation channel 210 has a section 270 twisted around the transportation direction 105 between the separation section 260 and the outlet port 230.

The first half of the shell 240 (Figure 2) has a first guide element 245 designed as a guide groove between the two guide tabs, the first guide element extending along the transport channel 210 from the inlet port 220 to the outlet port 230. Correspondingly, the second half-shell 250 (FIG. 3) has a second guide element 255 designed as a guide groove between the two guide tabs, which extends along the transport channel 210 from the inlet port 220 to Exit port 230. In this transport channel 210, the first guide element 245 and the second guide element 255 are arranged opposite to each other and define a strip plane for the fastening element strip 100 guided therein. The first guide element 245 and the second guide element 255 extend parallel to each other from the inlet port 220 to the separation section 260 and preferably extend throughout the separation section 260 so that the fastening element strip 100 runs along during transportation. The transport channel 210 is guided without twisting. In this way, it is ensured that the fastening element 115 is undisturbed in the separation section 260 to be separated. In the twisted section 270, the first guide element 245, the second guide element 255, and therefore the transport direction 105 are bent so that the fastening element strip 100 exits the outlet port 230 by moving the part away from the base come out. As a result, the risk of the fastening element strip 100 being trapped between the storage attachment 130 and the base after exiting the outlet opening 230 is reduced.

In addition, in the twisted section 270, the radius of curvature of the first guide element 245 is different from the radius of curvature of the second guide element 255, so the first guide element 245 and the second guide element 255 are in common and therefore there is also a transport channel 210 The direction of transport 105 is twisted by a twist angle A of, for example, 8° (FIG. 4 ). This causes the strip plane defined by the first guide element 245 and the second guide element 255 to twist between the separation section 260 and the outlet opening 230, and thus causes the fastening element strip 100 to be removed from the separation section 260 The period of transportation to the exit port 230 is reversed. With this twisting, the fastening element strip 100 will not bend and return to the bin attachment 130, so the interference to the work process is reduced by the fastening system.

Figure 4 shows the bin attachment 130 in a top view. The strip plane 280 defined by the first guide element 245 and the second guide element 255 is inclined at the outlet opening 230 by a torsion angle A relative to a plane 290 oriented perpendicular to the separation direction 265.

The present invention is shown by taking a separation device for the storage bin attachment of the driving device as an example. However, it should be pointed out that the separation device according to the present invention is also suitable for other purposes.
