Gripping device for at least 2 different gripping goods

The invention relates to a gripping device for at least 2 different gripping goods.

Gripping devices are designed such that the gripping surfaces hold the gripping material over a contact surface. A line contact could lead to a deformation of the gripping material. The gripping levers are adapted to the gripping material. If the gripping device, instead of a small pipe, grips a larger pipe surface, the gripping lever with the gripping surface is exchanged according to the prior art.

The invention has for its object to provide a universal tool for several items to be gripped and also to avoid set-up time.

This is achieved according to the features of the independent claim 1, characterized in that the gripping lever of a gripping device has a gripping surface with two faces, wherein the first faces of the gripping surfaces may comprise a first gripping surface, while the other faces of the gripping surfaces may comprise a different gripping surface ,

Advantageous embodiments of the invention will become apparent from the features of the dependent claims.

The invention will now be explained in detail with reference to FIGS. 1 shows the gripping device in engagement with a small gripping product and FIG. 1 shows the same gripping device in engagement with a larger gripping material.

FIG. 1 shows a gripping device with two gripping levers t, wherein each gripping lever 1 has a gripping surface 2. The gripping device has a further illustrated adjusting device for moving at least one of the gripping levers 1. The right gripper lever 1 has a pivot point 7 around which the gripping lever 1 can be rotated. The gripping surfaces 2 are each divided into two parts: centrally in the gripping surfaces 2 is in each case a first partial surface 5, which are surrounded by respective second partial surfaces 6. FIG. 1 shows that a first gripping material 3 is held flat by the first partial surfaces 5 of the gripping surfaces 2. The two gripping levers 1 form a relatively small angle.

FIG. 2 shows the same gripping device, wherein the second partial surfaces 6 hold a second, larger gripping product 4 flat. For this purpose, the right grip lever 1 is rotated counterclockwise about the pivot point 7, so that the two gripping levers 1 form a relatively large angle compared to Figure 1,

For gripping only the right gripping lever 1 is opened in the counterclockwise direction, the gripping material 3, 4 applied to the left gripping lever 1 and the gripping tool closed by turning the right gripping lever 1 clockwise.

According to the invention not only pipes can be kept flat. This is also possible with other cross sections.

Also, at least one of the gripping levers can be moved linearly instead of by rotation.

In general, it is particularly advantageous if the first partial surfaces 5 in the middle region of the gripping surfaces 2 can comprise the smallest gripping material 3 flatly, and the second partial surfaces 6 are arranged around this central region for covering larger gripping products 4 in a planar manner. The invention is not limited to two different gripping goods 3, 4, but can be continued as desired, wherein it makes sense that from the central region outwardly several areas for planar gripping larger gripping goods 3, 4 are arranged, wherein from the inside out the areas for larger and larger items 3, 4 are arranged. The adjusting device adjusts the gripping levers 1 in such a way that the gripping lever 1 and / or its angle increases relative to each other with the gripping material 3, 4 becoming larger in area.

In principle, however, it is also possible that the gripping surfaces 2 side by side have different partial surfaces 5, 6; However, this inevitably drops the gripping lever 1 longer.

The gripping device is usually in a more complex machine, which also supplies the gripping material 3, 4 and further promotes integrated. Furthermore, the gripping device can be located on a gripper arm, not shown, which moves the two gripping levers 1.
