- 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 support to 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 improve a known handling device in terms of their operation. This object is solved by the features of claim 1.
- a handling device comprising a drive carriage which is movable relative to a carrier, wherein a plurality of scissors links having scissors is arranged on the drive carriage, wherein at the second end of the scissor a movable by means of the scissors relative to the drive carriage carrier plate is arranged , wherein on the support plate, a gripping tool is arranged, wherein on the drive carriage a drive for operating the scissors and at least one guide rod is arranged, wherein the guide rod is coupled to the scissors for the purpose of their leadership in a coupling point when the scissors is moved.
- the guide rod is used for the purpose of forcing the scissors during their up and down movement.
- a length of the guide rod is for example approximately the distance of the scissors in the retracted state, so that it extends from the distance of the arrangement of the stroke scissor members on the drive carriage to the gripping tool, in particular its Rajpiatte, when the scissors has been completely collapsed.
- the at least one guide rod can be arranged either on the drive carriage, in particular its underside, and / or also on the gripping tool, in particular its upper side, in particular the upper side of the carrier plate.
- means are provided which are suitable and designed to determine the travel of the scissors in response to the operation of the drive of the scissors. With these means it is possible to determine the exact position of the gripping tool with respect to the position of the drive carriage. Since the drive carriage is always at a defined height in relation to a footprint or work surface of the handling device, these means can also be used to determine the distance between the gripping tool (and thus also the recorded object) with respect to this footprint or work surface.
- the height position of the gripping tool is determined from the operation of the drive of the scissors, for example the rotations of an electric motor
- the at least one guide rod preferably only one guide rod, a sensor element which is movable relative to the at least one guide rod is associated, wherein the sensor element is connected to one of the stroke scissor members of the scissors.
- a relatively movable coupling element is arranged on the guide rod and the coupling. Located in a crossing point of two associated Hub Scherengüeder.

- a suitably designed coupling element can then at least one strand of the scissors, but if necessary, both strands of the scissors can be coupled with this single guide rod for the purpose of forced operation.
- a sensor element can be provided on at least one guide rod or on the coupling element assigned to it in order to be able to determine the height position of the gripper tool at any time.
- a sensor element can also be arranged on both coupling elements or on both guide rods.
- the drive for the scissors is arranged centrally between the two guide rods arranged next to it.
- the effective drive for the scissors is also in a plane in which the vertical axis of the handling device is located. This arrangement and the positive guidance thereby improve the rest of the movement of the gripping tool (alone or with recorded object), if this is moved horizontally and / or vertically. This means that significantly reduced by this type of forced operation and the central arrangement of the drive for the scissor swing tendency of the gripping tool or vibration of the gripping tool is almost completely eliminated.

- these suction tulips 19 are operated in a controlled manner in order to absorb an object by suction by means of the vacuum. Thereafter, the object can be brought by means of the scissors 7 and / or the method of the drive carriage 2 in a different position and released by removing the vacuum on the suction tulip 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.
- 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 compressed air is transmitted via the interior of the lifting scissor members 8 from the device 21 to the gripper members 14.
- the connecting points of the scissor members 8 with each other and the attachment points 9, 10 seals are formed to avoid that at these points, where movable parts are connected to each other, compressed air (or vacuum) can escape.
- 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 members 14 are operated controlled by the drive motor 15 and in addition 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 output value of the sensor element 23 is transmitted wirelessly or by wire to the control device 6 (and possibly another control and / or monitoring device outside the handling device 1).
- the sensor element 23 is coupled via suitable coupling means, not shown, in a coupling point K with its associated scissors link 8. In this case, the guide rod 22 only serves the guided movement of the sensor element 23.
- 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 the scissor 7 up or moved together by means of the drive 18 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.

- 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 support to which in turn a trolley is arranged. For this purpose, open designs are known, so that these known trolleys very quickly pollute, only allow straight travels and are complex and voluminous in terms of their construction.
- the Schwenkhubantrieb with which the gripping tool is arranged on the movable carriage, has two guide rods, with which two functions are realized.
- a guide is realized with the two guide rods and, on the other hand, these guide rods serve to delimit the path.
- the way of the guide rods can be measured and is thus a measure of the projection of the scissors, that is, for each achieved lifting height of the Schwenkhubantriebes.
- the displacement measurement takes place advantageously wear-free indirectly by rotation of the drive motor, which is for example a stepper motor.
- the two guide rods cause a centering, so that there is also a forced centering in the region of the gripping tool.
