Abstract
A device (1) for the stepped displacement of workpieces inside a press (2) or similar processing equipment is provided. The device includes at least one or two gripper rails (4) that can be displaced back and forth in the direction of a longitudinal extent thereof and in the feed direction, the rails being displaced transversely in relation to one another in order to engage workpieces. To execute a gripping movement, the gripper rail (4) includes levers (5) that run at an angle and in opposite directions to one another, whereby the ends of the levers that face away from the gripper rail can be displaced towards or away from one another. Pivoting arms (11), which together with the levers (5) form scissors or half scissors type drives, are hinged on the levers (5) to guide the resultant transverse movement. A scissors drive of this type permits a parallel displacement of the gripper rail (4), even where space is limited, without the use of a drive that protrudes beyond the longitudinal extension of the gripper rails (4).
Claims (13)
1. Device (1) for stepped displacement of work pieces, in particular, within a press (2), comprising at least one or two gripper rail(s) (4), which can move back and forth in a feed direction for feed and return motions, which have gripper parts or gripper zones for engaging work pieces, and which can be moved for engaging the work pieces and for movements in the feed direction and then back into an original position, wherein at least two levers (5) that can pivot in parallel or mirror-symmetric to each other in a plane of motion, in a plane parallel to the plane of motion, or in a plane at an angle to the plane of motion are attached to the gripper rail(s) (4), and in a device with two parallel ones of the gripper rails (4), the levers (5) of one of the gripper rails (4) can pivot in an opposite direction to the levers of the other gripper rail (4), characterized in that the two levers (5) are hinged to the gripper rail (4) so that they can pivot and ends or zones thereof facing away from the gripper rail (4) are pivotably attached to sliding parts (6) that can move towards each other or away from each other parallel to a direction of the extent of the gripper rail (4), and a spacing of the sliding parts (6) is changeable for a back and forth movements of the gripper rail (4) perpendicular to a longitudinal extent thereof, and the gripper rail (4) is driven positively perpendicular to the direction of the longitudinal extent thereof.
2. Device according to Claim 1, characterized in that the levers (5) and a drive (7) of the sliding parts (6) are arranged at least partially within an outline of stands (3) of the press (2), especially between two press stands located adjacent to each other in the feed direction.
3. Device according to Claim 1 or 2, characterized in that the drive for the feed motions of the gripper rail (4) or gripper rails (4) is arranged in the direction of the longitudinal extent thereof at least partially within the outline of the stands (3) of the press (2).
4. Device according to one of Claims 1 to 3, characterized in that pivot arms (11), which are mounted pivotably with the ends thereof facing away from a hinge point (12) on the gripper rail (4) on displacement elements or stationary bearings (13), are hinged to the levers (5) between contact points (9) thereof to the gripper rail (4) and to the respective sliding part (6) and that a spacing of the sliding part (6), on one side, and the displacement element or bearing (13), on the other side, can be changed or enlarged for transverse adjustment or during the transverse adjustment of the gripper rail (4).
5. Device according to one of Claims 1 to 4, characterized in that the pivot arm (11) crosses the lever (5) at the hinge point (12) and also attaches to the gripper rail via a joint (14), wherein the hinge points (9, 14) of the lever (5) and the pivot arm (11) mounted pivotably to the lever on the gripper rail (4) can change in terms of a spacing therebetween when the gripper rail (4) moves perpendicular to a longitudinal extent thereof in a similar manner to a spacing between the sliding part (6) and the displacement element or bearing (13).
6. Device according to one of Claims 1 to 5, characterized in that the hinge point of the pivot arm (11) facing away from the lever and the gripper rail (4) is stationary and the hinge point (10) of the lever (5) adjacent to the other hinge point and located on the sliding part (6) can move relative to the other hinge point.
7. Device according to one of Claims 1 to 6, characterized in that the two sliding parts (6) of the two levers (5) attached to a gripper rail (4) can move towards each other for moving the gripper rail (4) closer to the sliding parts (6) and away from each other for an engaging motion and the hinge points (13) of the pivot lever (11) are, in particular, stationary.
8. Device according to one of Claims 1 to 7, characterized in that the gripper rail (4) or gripper rails (4) can move after engaging the work pieces in the direction of the longitudinal extent thereof, such that the hinge points (10) of the levers (5) and the pivot arms (11) each facing away from the gripper rail (4) can be moved by slides (15a) on a guide (15) arranged parallel to the gripper rail (4) and that, for example, a spindle motor or work cylinder or a linear drive is provided for the adjustment motion.
9. Device according to one of Claims 1 to 8, characterized in that for opposite-direction movements of the sliding parts (6), a spindle (16) having two opposite-direction threaded zones and spindle nuts (17), which have opposite-direction threads on the sliding parts (6) and to which the respective threaded zones of the spindle (16) attach is provided, and the spindle (16) has a separate drive motor (7).
10. Device according to one of Claims 1 to 9, characterized in that sleds (14) of the gripper rail having hinge points (10) of the lever (5) facing away from the gripper rail (4) are coupled with each other or connected via a connecting rod and a separate feed drive (8) is provided for each gripper rail (4).
11. Device according to one of Claims 1 to 10, characterized in that the pivot arm (11) for attachment to the respective lever (5) can move in a plane that extends at an angle to the plane in which the lever (5) can move.
12. Device according to Claim 11, characterized in that the pivot arms (11) extend at an angle upwards or downwards relative to the plane of motion of the levers (5) independent of whether the plane of motion of the levers (5) is arranged horizontally or also at an angle upwards or downwards relative to a horizontal plane.
13. Device according to one of the preceding claims, characterized in that the drive devices for the gripper rails are mounted on vertical supports (21) and/or threaded spindles (20) and can move up and down.
