Thereafter, the object can be brought by means of the scissors 7 and / or the method of the drive carriage 2 in another position and released by removing the vacuum on the Ansauguipen 19 again and stored with it. If the vacuum is transmitted through the interior of the lifting scissor members 8, these are sealingly connected together. This means that not only the connection points of the scissors members 8 with each other, but also the attachment points 9, 10 are formed correspondingly tight to allow the transmission of the vacuum. The same applies to the connection of the upper ends of the lifting scissor members 8, which on the
- Drive carriage 2 are arranged, up to the device 20 for generating a vacuum.
- a device 21 for generating compressed air is provided in the drive carriage 2.
- the compressed air generated by the device 21 can be transmitted via compressed air hoses to the gripping elements 14.

- the two devices 20, 21 may each be present alone, so that the gripping tool is operated either only with a vacuum or only with compressed air. It is also conceivable that the gripping elements 14 are operated controlled by the drive motor 15 and additionally the suction tulips 19 are present, so that in this case in addition to the drive motor 15 and the device 20 for generating a vacuum is present. In this case, the device 21 for generating compressed air can be omitted. In addition, it is conceivable that the gripping elements 14 are operated by means of compressed air, so that in this case in addition to the Ansaugulpen 19 and the device 20 for generating a vacuum and the device 21 for generating compressed air is present.
- the scissor lift 7 comprises two strands of scissor lift members 8

- FIG. 4 shows that the guide rod 22 does not have a sensor element
- the coupling element 23 is coupled, but has a coupling element 24.
- the coupling element 24 is coupled, but has a coupling element 24.
- the coupling 24 can be moved relatively linearly to the guide rod 22 when using the Drive 18 the scissors 7 up or moved together and thus the height H is changed.
- the coupling ensures a targeted positive guidance of the scissors 7. It is thus avoided that the scissors 7 can come into vibration during their process.
- the height H ie its change or current value (such as, for example, the end points or points therebetween) by further detection means (such as a laser distance measurement between the drive carriage 2 and the carrier plate 11).

- the angle of the lifting scissor members 8 arranged there can be changed with respect to the surface of the support plate 11. This is done when the scissor 7 is opened or closed.
- the respective guide carriage 41 is slidably disposed on a guide rail 42 and thus is positionally variable with the guide carriage 41 in operative connection.
- the carrier plate 1 and thus the entire gripping tool always centered (in the sense of a defined position) with respect to the drive carriage 2 or in relation to the scissors 7 is aligned.
- This centering is not always given for example by shocks when receiving the object.
- the scissors 7 can on the operative connection of the guide carriage 41 with the guide rail 42 with respect to the gripping tool be aligned.
- compensation means 44 are arranged on a base 43 of the support plate, is effected with the compensating means 44 that then, if the scissors 7 is no longer aligned centrally to the gripping tool, a return to the centrally aligned position is ensured .
- These compensating means 44 may be, for example, spring elements. It is also conceivable not to arrange the compensating means 44 on the base 43 of the carrier plate 11, but to arrange and secure the compensating means 44 (for example in the form of a cable) to the two opposite guide carriages 41 and via at least two, preferably three deflecting rollers are arranged and fixed on the support plate 11, to deflect.
- the carrier plate 1 is designed as a one-piece planar structure.
- the support plate 1 in sandwich construction. This means that there are two flat structures (similar design and / or dimension or different design and / or dimension), which are rotatable about a central pivot point relative to each other.
- the guide rods are located with the gripping elements and their associated storage.
- the gripper members can be rotated about the vertical axis of the handling device 1. This twist can be stepped (for Example by 90 °) or steplessly controlled.
- an adjustment of the position of the gripping elements 14 with respect to the male object is possible.
- the detection of the position of the male object can be done for example by suitable image capture means.
- FIG. 8 a particularly preferred embodiment of the centering of the gripping tool with respect to the center vertical axis of the scissors 7 and the drive carriage 2 is shown.
- the respective scissor members 8 are in turn arranged on a respective guide carriage 41.
- a guide carriage 41 is associated with a fixed to the support plate 11 guide rail 42 and is in operative connection with this.
- deflection rollers 45, 46 and 47 are mounted on the support plate 11 in the arrangement shown.
- One end of a cable 48 is attached to the one end of the guide carriage 41 of the one strand of the scissors 7 and the other end to the opposite guide carriage 41 of the same strand of the scissors 7. Due to this staggered arrangement of the deflection rollers 45,46 and 47 and the corresponding offset and the resulting leadership of the cable 48 on the one hand a guided linear reciprocating motion of the gripping tool is allowed, but on the other hand also causes, if a deflection of the centered position occurred (for example, due to an external impact), the gripping tool returns to its center position with respect to the vertical axis of the handling device 1.
- the arrangement shown in Figure 8 the deflection rollers 45, 46 and 47 and the cable 48 on the other side of the scissors 7, that is, on the opposite strand of the scissors 7, are arranged.
- this in 8 arrangement can also be an arrangement of only two deflection rollers into consideration, wherein the one deflection roller on the support plate 11 is arranged approximately in the region between two guide carriage of a strand of the scissors 11 and causes an offset of the cable.
- a further deflection roller is present on the support plate, which realizes a deflection of the cable to about or exactly 180 °.
- the latter arrangement is preferably realized in the one strand of the scissors 7, in which case in the other strand of the scissors 7, the arrangement shown in Figure 8 is present.
- pallet robots that are used for moving objects.
- Objects are, for example, flat structures such as cardboard, wooden boards and the like. But it can be offset with such a pallet robot and other items such as europallets, boxes and the like.
- the pallet robot has a gripping tool, wherein the gripping tool height is movably arranged on a carrier also movable. It is known to arrange for moving the gripping tool, for example on a ceiling of a machine shop or on an elevation a T-shaped carrier on which in turn a trolley is arranged. For this purpose, open configurations are known, so that these known trolleys pollute very quickly, only allow straight travels and are complex and bulky in terms of their construction.
- the invention has for its object to provide a pallet robot with a drive for a gripping tool available, which is improved over the known prior art.
- an H-shaped support in which the drive, the power supply for the drive, the data transmission for the control of the drive and optionally the gripping tool and support means between the two legs of the H-shaped support are arranged and covered.
- This compact design avoids soiling and thus wear and significantly reduces the weight. This makes it possible, in particular in an elevation of the H-shaped beam to realize larger travels, without having to intervene against the ground must be done.
- the motor is integrated in the region between the legs of the H-shaped carrier.
- the drive wheel which is driven by the motor, is decoupled from the supporting wheel, so that the drive wheel is located in the middle of the "H", while on the other side of the "H” counter wheels are present for support. These mating wheels are spring-mounted, so that cornering is possible.
- the power rail for powering the drive motor can be integrated within the two legs of the H.
- the drive wheel which carries counter-wheels and other important elements required for the function, can be closed on one or both sides with a cover to prevent soiling, and one side of the movable carriage can be folded away so that not only simple assembly but also easy assembly Even a simple replacement or easy maintenance is possible.
- the H-shaped support is given a very stable arrangement over its longitudinal extent, so that either no central supports or very little central supports are required.
- such a carrier has very high moments of inertia relative to the slide, so that it is not only very stable, but ideally no anchors are required on the ground.
- the dynamic loads are minimized and there are very low shear forces during operation in the process of the carriage and thus in the process of gripping tool.
