Description

Device for processing a ski bearing a binding

Technical area

The invention relates to a device for machining a ski bearing a binding with a roller table for the ski, with each other with respect to the roller table in pairs opposite conveyor rollers, transversely movable to the roller conveyor for the conveyor rollers whose axes of rotation transverse to the support surface of the roller table and each other in pairs are inclined, and with a resilient actuator for the carrier for lateral hiring the conveyor rollers to the ski.

State of the art

The promotion of skis with mounted binding along a roller table, for example, to edit the steel edges makes it difficult because on the ski attachable conveyor rollers generally require a bridging of the bond. Of course, this also applies to monoskiers and snowboards, so that in the following, the term ski also includes monoskiers and snowboards.

So that the mounted binding can not interfere with the use of conveyor rollers the Skivorschub, has already been proposed (EP 1 129 748 A1) to hire the conveyor rollers each other in pairs opposite to the side walls of the skis. For this purpose, the conveyor rollers are mounted on carriers in the form of mutually opposing pivot levers, which are drivingly connected via a pair of meshing gears, so that when pivoting one of the pivot lever by means of a pivoting cylinder of the drive-connected pivot lever is swiveled in opposite directions. Because of these mutually symmetrical pivoting movements of the pivot lever, the ski to be processed is centered between the bearing on the pivot levers, acting laterally on the ski conveyor rollers relative to the longitudinal center of the roller table. However, the axes of rotation of the conveyor rollers do not run perpendicular to the support surface of the roller table, but to each other and inclined in the conveying direction to additionally press the ski to the roller table. A disadvantage of this known device, however, is that due to the relatively large for the processing of skis and snowboards pivoting range of the conveyor rollers pivoting lever not only the point of the conveyor rollers on the ski depending on the ski width relative to the machining tool is axially displaced, but with the Swing angle and the inclination of the conveyor rollers relative to the ski changes, which affects the machining accuracy. In addition, because of the inclination of the axes of rotation of the conveyor rollers, the ski can only be processed in one conveying direction.

Presentation of the invention

The invention is therefore based on the object, an apparatus for processing a binding bearing ski of the type described in such a way that regardless of the respective ski width consistent machining conditions can be ensured due to an editable ski guide during processing.

The invention solves the problem set by the fact that each acted upon by a resilient actuator support in slidably mounted transversely to the roller guides and are pivotable about a lying in a normal plane to the longitudinal direction of the roller table pivot axis to both sides, the transverse to the in the Normal plane pivoted axis of rotation of the associated conveyor roller runs. Since the carriers are slidably mounted in accordance with these measures in transverse to the roller guide and can be acted upon by a resilient actuator, the mutual distance of the pairwise opposite carrier for the conveyor rollers can be adapted to the respective ski width, without an axial displacement to be feared by the conveyor rollers certain supports against the processing tool. The loading of the carrier on separate, resilient actuating drives also allows a preset of the carrier at least on one side of the roller table according to the width of the ski to be processed, which simplifies the sequential processing of skis in a predetermined width range. Due to the displacement guide of the carrier, the inclination of the pivoted into the normal plane axes of rotation of the conveyor rollers relative to the roller table and thus does not change with respect to the leading ski. However, the additional pressing of the ski to the roller table due to the inclination of the axes of rotation of the conveyor rollers in the conveying direction is dependent on the direction, so that in a ski processing in opposite directions of conveyance, the axis of rotation of the conveyor rollers must be pivoted accordingly. This pivoting is made possible by the support of the carrier on corresponding pivot axes, wherein for the axes of rotation of the associated conveyor rollers on both sides of the normal plane ver limited inclination positions for each conveying direction of the ski arise.

Run the guides for the carrier parallel to the pivot axis of the carrier, so there are simple construction conditions. However, it must be taken into account that results in the displacement of the conveyor rollers transversely to the support surface of the roller table with the adjustment of the carrier along the guides.

If the pivot axes for the carriers are fastened to support plates connected to the associated actuating drives and displaceable along the guides, this results in an advantageous embodiment, which on the one hand slidability and on the other hand taken into account the pivotability of the wearer, with a small footprint.

As has already been stated, the loading of the carriers via separate actuating drives offers the possibility of displacing at least the carriers on one side of the roller table transversely to the roller table independently of the opposite carriers for adaptation to a predetermined ski width. However, this adaptation to different widths does not need to be done via the actuators themselves. Since all carriers of a page must be adjusted together to adapt to a ski width, the guides for the support of the conveyor rollers on one side of the roller table can be arranged in a transverse to the roller table adjustable slide, with the help of the joint adjustment of the carrier together with their guides can be made so that serve the carrier resiliently acting actuators only for hiring the conveyor rollers to the side walls of the ski. This means a comparatively small stroke for these resilient actuator drives.

With a limitation of the stroke of the resilient adjusting drives for the displacement of the carrier along their guides, the adjusting drives can be performed in a simple manner as a spring store, which act on the carrier in the sense of employment of the conveyor rollers on the ski. Since the ski to be processed between the pairwise opposed conveyor rollers must be guided aligned lengthwise, to ensure equal loading forces of the opposing actuator drives. For this reason, the spring-loaded with adjustable spring preload be carried out in order to achieve a corresponding adjustment of the spring forces for accurate skiing.

Spring storage as adjusting drives for employment of the conveyor rollers to the ski, however, require an additional return drive, which can be formed for example in the form of an actuating cylinder. To avoid such additional reset drives, the actuators can act on the carrier for the pairwise opposed conveyor rollers consist of adjusting cylinders. These adjusting cylinders are to act on to fulfill their leadership tasks synchronously. For this purpose, the pistons of this actuating cylinder are drivingly connected to the pistons of two mechanically coupled compensation cylinders via a hydraulic linkage, wherein the actuating cylinder and the compensating cylinder are acted upon in opposite directions for displacement of the carrier alternately. About the action of the balancing cylinder, the pistons of the actuating cylinder are displaced via the hydraulic linkage. An actuation of the actuating cylinder causes an opposite adjustment of the piston of the balancing cylinder, again via the hydraulic linkage. The mechanical coupling of the two compensating cylinder due to the respective matching displacement volume a synchronous movement of the two actuating cylinder.

The loading of the actuating cylinder must be resilient, to ensure that the conveyor rollers can follow the curved course of the side edges of the ski. This can be ensured in a simple manner that the actuating cylinder and the compensating cylinder are alternately applied pneumatically. About the pneumatic loading of the cylinder, the spring action of the application is achieved. But it is also possible to apply the actuating cylinder hydraulically. In this case, the compensation cylinders are to be applied pneumatically, while the adjusting cylinders are acted upon hydraulically via a pressure accumulator. This pneumatically actuated pressure accumulator in turn ensures the resilient compensation.

Way to carry out the invention

As shown in FIGS. 1 and 2 it can be seen, the apparatus shown for processing a binding bearing ski 1 a frame with two separate frame parts 2, 3, of which the frame part 2 a guide 4 for the designed as a carriage frame part. 3 wearing. Each of these frame parts 2, 3 is provided with rollers 5, 6 of a roller table 7 for conveying the ski 1 perpendicular to the guide 4. To drive and hold down the ski 1 on the roller table 7 serve conveyor rollers 8, which are driven by electric motors 9 with the interposition of an angle gear. For the storage of the conveyor rollers 8 supports 10 are provided, which preferably form the housing for the angular gear and are mounted on pivot axes 11. The pivot axes 11 themselves are mounted on support plates 12 which are mounted with the aid of guides 13 in brackets 14 transversely to the roller table 7 slidably. For hiring the pairwise with respect to the roller table 7 opposite conveyor rollers 8 to the side cheeks of the ski, the carrier 10 are each acted upon with resilient actuators 15. These actuators 15 are formed in the case of the embodiment of FIGS. 1 to 5 from spring 16, which engage the support plate 12. Since, with the aid of the elastic adjustment of the conveyor rollers 8 on the side cheeks, the ski 1 is extended in the longitudinal direction. directed to be performed on the roller table 7, the spring loading of the opposing conveyor rollers 8 must match. To set the spring preload of the spring 16 each spring 16 is provided with a screw 17 for adjusting the spring preload, as shown in FIG. 5 can be removed. Since the actuator drives 15 formed from spring memories 16 can apply the carrier 10 only in the sense of employment of the conveyor rollers 8 on the side cheeks of the ski 1, separate drives must be provided for the return of the conveyor rollers in a starting position. According to the embodiment, return cylinders 18 are used for this purpose. In order to achieve a secure against tilting guidance and loading of the support plate 12, the guides 13 composed of two ball roller guides which are diametrically opposite each other with respect to the restoring cylinder 18, as shown in FIG. 3 can be removed. Since the spring stores 16 are also constructed from two spring units diametrically opposite one another with respect to the return cylinder 18, a substantially symmetrical loading of the support plate 12 results, on the one hand, through the spring store 16 and, on the other hand, through the return cylinder 18.

As shown in FIGS. 2, 4 and 5, the axes of rotation 19 of the conveyor rollers 8 in a central pivot position of the carrier 10 in a normal plane to the roller table 7 are not perpendicular to the support surface of the roller table, but inclined to each other, so that over the peripheral surface of the conveyor rollers. 8 on the ski 1 directed against the roller table 7 hold-down force can be exercised. This hold-down force can be enhanced by an additional pivoting of the carrier 10 about the pivot axis 11 against the conveying direction. Such pivoting causes pivoting of the axis of rotation 19 from the normal plane with respect to the roller table 7, so that on the conveyor rollers 8 an additional transverse to the support surface of the roller table 7 directed component of the conveying movement occurs. The stop-limited pivotal position of the carrier 10 must therefore be changed depending on the conveying direction, so that the conveyor rollers the ski not a him from the rolling 7 granting subsidy component. In Fig. 3, two pneumatic diaphragm cylinder 20 are indicated, which are mounted on a support bracket 21 of the support plate 12 and provide by alternately acting for a pivoting of the dash-dotted lines indicated carrier 10 between the two stop positions.

For machining a ski 1 by means of machining tools 22, which are shown in FIG. 1 as cup-shaped grinding wheels, the device is first adapted to the maximum width of the ski to be machined by the frame part 3 is displaced on the guide 4 accordingly. Since the rollers 5 and 6 of the roller table 7 are assigned on the one hand to the frame part 2 and on the other hand the frame part 3, with the adjustment of the frame part 3 and the roller table 7 is adapted to the width of the ski 1 to be processed. By manually advancing the launched on the roller table 7 ski 1 against the inlet side conveyor roller pair 8 is first actuated by the ski 1, a rocker switch 23 so that the conveyor rollers 8 by means of the resilient actuators 15, in the case of the embodiment with the help of the released spring 16 , are made to the side cheeks of the ski 1 to feed the ski 1 aligned editing tools 22 in the longitudinal direction, which are turned on and employed when a arranged between the inlet side conveyor roller pair 8 and the machining tool 22 rocker 24 is operated by the incoming ski 1 , In addition, the outlet-side conveyor rollers 8 are also delayed in time employed on the ski 1 in order to continue conveying the ski until the ski end releases a further switching rocker 25 between the machining tool 22 and the outlet-side conveyor rollers 8. With the release of this switching rocker 25, the outlet-side conveyor roller pair 8 can be reversed in its direction of rotation with a corresponding setting of the control program to subject the ski 1 during a return to a second processing operation. The reversal of the inlet-side conveyor rollers 8 can be made with the release of the switching rocker 24. The renewed changeover of the conveying direction for a third work cycle is initiated with the release of the rocker switch 24. passes. After completion of the processing of the ski 1 of the device can be removed on the outlet side. Since the inclination of the axes of rotation 19 of the conveyor rollers 8 parallel to the roller table 7 depends on the conveying direction of the ski 1, the pneumatic diaphragm cylinder 20 must be reversed with the direction of rotation of the conveyor rollers 8, which can be ensured via the associated paddle shifters 24 and 25.

According to the embodiment of FIGS. 1 to 5, the resilient employment of the conveyor rollers 8 takes place on the side cheeks of the ski 1 by means of the spring 16, which return cylinder 18 requires to move the conveyor rollers 8 against the force of the spring 16 in their starting position. Of course, the invention is not limited to such an embodiment of the actuator 15. 6 and 7, two possible embodiments of such actuators 15 are shown in the form of Stellzylindem 26, the resiliently act on the support plate 12 for pivotally receiving the carrier 10 and retract back to the starting position. According to FIG. 6, the necessary synchronization of the loading of the support plates 12 is achieved by two compensating cylinders 27, the pistons of which are drivingly connected by a coupling 28. The pistons of the actuating cylinder 26 are coupled to the piston of the balancing cylinder 27 by a respective hydraulic linkage 29, so that a movement of the piston of one cylinder forces a corresponding movement of the other of the two connected by the hydraulic joint 29 cylinder 26, 27. The actuating cylinder 26 and the compensating cylinder 27 are alternately acted upon pneumatically via a control valve 30, which is connected to a pneumatic pressure line 31 and a corresponding return line 32. If the compensating cylinder 27 is pressurized in the drawn valve position, the actuating cylinders 26 are actuated via the hydraulic linkage 29 in the sense of setting the conveyor rollers 8 against the ski 1, the pneumatic action bringing about the spring effect. To reset the conveyor rollers 8, the actuating cylinders 26 are to be acted upon, which requires a changeover of the control valve 30. The adjusting drives 26 according to the exemplary embodiment of FIG. 7 are in turn drive-connected via a hydraulic linkage 29 with compensating cylinders 27, whose pistons carry a mechanical coupling 28. The loading of the compensating cylinder 27 via the control valve 30 pneumatically, but the actuating cylinder 26 but hydraulically. For this purpose, a pressure accumulator 33 is provided, via the hydraulic part, the loading of the actuating cylinder 26 takes place. The pneumatic part of this pressure accumulator 33 is connected to the control valve 30, so that despite the double-sided hydraulic actuation of the actuating cylinder 26 results in a resilient employment of the conveyor rollers 8 to the ski 1.

Instead of the actuating cylinder 26 could also mechanical actuators 15 occur, which are actuated by pneumatic cylinders to ensure the spring action in the employment of the conveyor rollers 8 to the ski 1. In a one-sided action on these mechanical actuators via the pneumatic actuating cylinder, however, the provision of the conveyor rollers would have to be made via a return spring.
