Description

[0001] The invention relates to a device for processing the running edges of a sports device, in particular a ski or a snowboard, according to the preamble of claim 1.

[0002] Such devices are already known and are used for the automated processing of skis, in particular for preparing the running surface and grinding the edges, as can be seen, for example, from DE 43 21 450 A1 or US 2013 / 178136 A1.

[0003] In previous devices, the individual processing units for the running edge were arranged in such a way that first the side surface of the running edge was processed and then the lower edge was processed with a so-called tuning angle of a few degrees deviating from the orientation of the running surface covering.

[0004] The object of the invention is to provide a device for processing the running edges of a sports device, in particular a ski or a snowboard, according to the preamble of claim 1, with which more precise and sharper cutting edges and thus improved grip of the ski can be achieved. Furthermore, minimal removal of the metallic material of the running edges and thus a long service life of the ski should be achieved.

[0005] To solve this problem, the invention proposes a device with the features of claim 1.

[0006] In contrast to known devices according to the prior art, the invention (after a planar pre-machining of the running surface and the underside of the running edge) involves an automated movement sequence in which the underside is first machined – preferably at a specific tuning angle of a few degrees – and then the side surface of the running edge. In the latter step, an initially undesirable burr is formed, which points downwards from the side surface of the running edge. According to the invention, this burr is then removed in a preferably final machining step by means of a deburring device, ultimately resulting in a precise and sharp cutting edge between the underside, which was machined first, and the side surface, which was machined subsequently.

[0007] The movement of the sports equipment is automated by the transport device. This movement can include straight sections, particularly in the area of ​​the individual processing stations, where the direction of movement runs parallel to a longitudinal direction of the sports equipment. However, the movement does not have to proceed continuously in a straight direction. It is essential that the sports equipment is guided by the automated movement sequence first to the bottom edge processing unit, then to the side edge processing unit, and finally to the deburring unit, and preferably moved through these units. Prior to the bottom edge processing unit, a running surface processing unit is positioned, which flattens the running surface of the sports equipment and a flush-adjacent underside of at least one running edge.

[0008] Further advantages and details of the invention are explained in more detail with reference to the following description of the figures.

[0009] The Fig. 1 A schematic view shows the devices for processing the sports equipment in the embodiment of the invention, which they will pass through one after the other.

[0010] The Fig. 2 Figure 1 shows a schematic side view of a further embodiment with a transport device that can be temporarily connected to the sports equipment for the automated movement of the sports equipment relative to the individual devices that process the sports equipment, in particular the running surface and the running edge.

[0011] The Fig. 3 Figure 1 shows an embodiment of a running surface processing device in a schematic cross-section perpendicular to the longitudinal direction of the sports equipment or perpendicular to the direction of movement of the same in a device according to the invention.

[0012] The Fig. 4 shows an embodiment of a bottom edge machining device according to the invention in a similar representation to the Fig. 3 .

[0013] The Fig. 5 shows an embodiment of a side-edge machining device, also in a representation similar to that in the Fig. 3 .

[0014] The Figures 6a, 6b, 6c and 6d Each shows exemplary embodiments of a deburring device according to the invention in a similar representation to the Figures 3 to 5 .

[0015] Fig. 7 shows the last section of the embodiment of a device according to the invention, as seen in the direction of movement x, in a perspective view.

[0016] As described in the following exemplary embodiments, the invention involves, on the one hand, side edge processing following bottom edge tuning, and on the other hand, a deburring device is used as a preferably final step.

[0017] The Fig. 1 schematically shows a running surface machining device 1, which - viewed in the direction of movement x - is followed by a bottom edge machining device 2, a side edge machining device 3 and a deburring device 4.

[0018] According to the invention, the lower edge processing device 2 is arranged in front of the side edge processing device 3, in contrast to the prior art, and is followed by a deburring device 4 which removes the burr formed on the running edge by the side edge processing device.

[0019] At the in Fig. 2In the illustrated embodiment, a frame 5 or support or the like is generally shown, which is fixed in space and holds the individual components of the device according to the invention. A transport device 6, for example, can be temporarily connected to the top of the sports equipment 9 by means of retaining elements 8 that can be raised and lowered via the direction of arrow 7, for example by applying a vacuum. However, other mechanical retaining elements are also conceivable and possible.

[0020] The transport device 6 moves the sports equipment 9 in the direction of movement x past the individual processing devices 1 - 4. This is done automatically and controlled by a computer unit (not shown), which is known per se.

[0021] In the illustrated embodiments, the first step involves processing the running surface covering and the adjacent underside of the running edge.

[0022] This is illustrated in detail using one of the two running edges of the sports equipment. In the illustrated embodiment, the running surface processing device 1 has two rotary grinding elements arranged one behind the other. Several, in particular four, such rotary grinding elements can also be provided to implement the following steps: Coarse pre-grinding (high processing intensity with high material removal), pre-grinding (completes the pre-grinding with a finer structure), smooth grinding (smoothing all fine hairs and fibers of the running surface and the edge), structure grinding to create a perfect surface design.

[0023] In Fig. 3The running surface is designated 10. It is located on the underside of the ski body 11 of the sports equipment 9. The metallic running edge 12 has an edge leg 12a, which is anchored in the ski body 11 in a manner known per se. The actual running edge is formed by the edge web 12b, which has a bottom surface 13 and a side surface 14. The bottom surface 13 is sometimes also referred to as the bottom edge, and the side surface 14 sometimes as the side edge.

[0024] The underside is flush with the lower surface of the tread covering 10 and is in the Fig. 3 The work step shown involves machining the running surface to obtain a flat geometry across the running surface covering 10 and the underside 13 of the running edge 12. This machining is carried out, for example, using a sanding belt (especially corundum sandpaper) or – as shown in Fig. 2This is demonstrated using grinding wheels, whereby grinding tools with ceramic-bonded abrasive particles can be used in particular. Fig. 3 This essentially corresponds to the state of the art.

[0025] New to the device according to the invention is a lower edge processing device 2, as described in Fig. 4 shown is the - seen in the direction of movement x - in front of the side edge processing device 3 according to Fig. 5 lies. These two processing facilities are followed according to the Figures 4 and 5 then also a deburring device 4, exemplary embodiments of which are described in the Figures 6a, 6b, 6c and 6d are shown.

[0026] In Fig. 4The lower edge processing device 2 is explained in more detail using an exemplary embodiment. It advantageously produces an underside surface on the running edge that runs straight in cross-section to the longitudinal direction of the sports equipment 9 and is aligned at an adjustable tuning angle α to the flat running surface 10 – more precisely, its underside. The tuning angle is very relevant for the ski's handling characteristics and can preferably be set between 0.2° and 1°. A small lateral burr 15 may form during this step, but this is not relevant because it is removed in the following step according to... Fig. 5 This small burr is automatically removed during edge machining anyway.

[0027] At the in Fig. 5In the illustrated embodiment of a side edge processing device 3, the side edge 14 is processed at an angle β to a perpendicular angle to the underside of the running surface covering 10, thereby creating a burr 16 that points downwards.

[0028] For processing the bottom and side edges, motor-driven grinding belts, preferably corundum sandpaper, are particularly suitable. Motor-driven grinding wheels, especially those with ceramic-bonded abrasive particles, are also a viable option. Likewise, motor-driven cup wheels, particularly those with ceramic-bonded abrasive particles, are possible. In addition to corundum-based abrasive particles, diamond-based particles can also be used.

[0029] The device according to the invention is, as the example in Fig. 2The diagram shows that the machine is designed so that deburring is the last step in the process, carried out by a deburring device that is the last one positioned in the direction of movement.

[0030] The Figures 6a, 6b, 6c and 6d show exemplary embodiments of such a deburring device.

[0031] In the Fig. 6a In the illustrated embodiment, the deburring device 4 comprises a machining element that is stationary relative to the frame 5 of the device during operation, and the transport device 6 moves the sports equipment 9 past it. The burr 16 rubs against the stationary machining element 17 and is thereby removed.

[0032] Such a stationary machining element 17 can be, for example, a stationary grinding wheel, a file, or a grinding rubber, particularly with diamond abrasive particles. The position of the stationary machining element 17 can be advantageously adjusted relative to the frame 5. With a flat grinding surface, the position will be adjusted so that it corresponds essentially to the tuning angle α according to Fig. 4 corresponds.

[0033] The Fig. 6d also shows fixed machining elements 17, which here consist of dimensionally stable pins with ceramic-bonded abrasive particles.

[0034] In the exemplary embodiments according to the Figures 6b and 6c Movable machining elements are provided, in particular machining elements driven rotaryally by means of a motor (not shown). In the case of the Fig. 6bThe illustrated embodiment is a brush 18 whose axis of rotation is parallel to the direction of movement. This lies in Fig. 6b perpendicular to the plane of the drawing and is labelled 19.

[0035] At the in Fig. 6c The illustrated embodiment also uses a brush as a processing element, which is driven by a rotary motor. Here, the axis of rotation 20 is perpendicular to the direction of movement x.

[0036] At the in Fig. 7The illustrated embodiment shows the output-side end region of a device according to the invention with a side-edge machining device 3 in the form of a rotating grinding wheel and a deburring device 4 with a stationary machining element 17 in the form of a grinding pad 17. This grinding pad 17 rests on a carrier 21, the position of which relative to the frame 5 is adjustable. For this purpose, the carrier 21 is pivotable about the axis 22. The pivot position can be adjusted via the adjusting wheel 23. The design essentially corresponds to the Fig. 7 the schematic representation of the Fig. 6a .

[0037] In the Figures 6a, 6b, 6c and 6d as well as in the present Figures 3 to 5 and in the Fig. 7Only one of the two sides of the sports equipment 9 is shown in each case. Typically, the sports equipment is essentially symmetrical to its longitudinal direction (center line) and has mirror-symmetrical running edges on the left and right. Accordingly, the processing devices are advantageously designed to process both the left and right running edges simultaneously in a single pass. This feature, in itself, represents the state of the art.

[0038] A further step is required for the complete preparation of the ski, namely the waxing of the running surface, which, however, is not directly related to the preparation of the running edge according to the invention and is therefore not described in more detail here.

[0039] Overall, the device according to the invention allows for the formation of a more precise and sharper cutting edge on the running edge of a sports device, in particular a ski or snowboard, thereby increasing the grip of the sports device. The process can be carried out in such a way that the abrasive wear of the metallic running edge is kept to a minimum, thus ensuring a long service life for the sports device.

[0040] The angles shown above, namely the tuning angle α and the side edge angle β, can preferably be set electronically via a control computer. However, manual adjustments are also conceivable and possible. The same applies to the angle, orientation, and position of the deburring device 4. This, too, can be set either manually or automatically from a central control computer.

[0041] The individual components can be mounted on a common frame or support. However, it is also possible, for example, to design the deburring unit separately or to arrange it outside the rest of the system, perhaps with a wax station. This also allows for easy retrofitting of existing systems that otherwise require only minor modifications. Reference symbol list:
