Abstract

The invention relates to a robot-based feeder device for feeding any starting molds heated to forging temperature to a forging machine. The object of the invention is to shorten the feed cycle to increase the productivity of the forge machine while achieving a trouble-free, layered delivery of any desired shape. The invention has for its object to influence the arrangement of robotic devices and its movement. Geloest this task by diametrical arrangement of two identical robot units with each other independent movement of the gripper on a common turntable, which confront each other of the Erwaermungsanlage and the forging and after each turn to 180 simultaneously take a heated output form of the Erwaermungsanlage and a heated output form to the Hand over the forging machine.

Explanation of the essence of the invention

The object of the invention is to influence the arrangement of robotic devices and their sequence of movements on a feeder of the type mentioned at the outset.

According to the invention, this object is achieved in that two robot units are arranged on a common rotary unit whose gripper units are preferably diametrically opposite, perform independent movements and alternately facing each rotation of the rotary unit of the heating system and the press, thereby simultaneously adopted a heated output form of the heating system and a previously transported heated output form is transferred to the supply station or first forming station in a defined position " ,

The execution of the rotary unit can be done in the same or changing direction of rotation, preferably by 180 °. Since a heated starting shape of the forging machine is supplied after each rotation of the rotary unit, it is thus possible to significantly reduce the loss times compared to the use of a single, one-armed robot unit, so that the automation of small and medium quantities is economical / ^: .. '' , '. '..'. , In another feature of the invention, the robotic units are mounted in adjustable positions on the turntable for additional adaptation to different pitch conditions.

The inventive device allows a particularly space-saving installation of heating © plant and forging machine when robotic units been with swivel gripper ven & © nd © t _e before the rotation of the rotary unit a © total buckled position before "preferably by 90 °, taking" so that the transport radius is significantly reduced «

Ausführungebeispiel

The invention will be explained in more detail below using an exemplary embodiment 10.

Heating system ejected output form and upper IC give an output form to the supply station of the forging machine »

Fig. 2 is a schematic perspective view of the feeder in the position before the rotation of the rotary unit and

Fig. 3 is a scheroatische perspective Aneicht the feeder after rotation of the Dr h heinheit by 180 °.

The feeder consists of zwsi _e on a rotary unit diametrically arranged robot units 1 and 6 "These are '25 in an adjustable position, z 'B. by T-slots and T-bolts, with the mounting flange 5 and 10 screwed to the rotary unit 11.

The robot units are equipped, as is known, with horizontally movable linear units 2 or 7 and vertically movable linear units 3 and 8 for programmable rapid adaptation to different dimensions and positions of the outward forms and pivotable grippers 4 and 9, respectively . The rotating unit which is designed and driven in a known manner has a base frame 12 which is either fixed or movable "on the floor according to the respective requirements".

The mode of operation of the feeders is as follows:

In the illustrated position of the feeder, the first robot unit 1 faces with buckling gripper 4 a heating system 13 and engages a lying in the outlet chute 14 limited by a longitudinal stop 15, heated to forging temperature output form 21. At the same time, the second robot unit 6 is stretched Gripper facing a forging machine 18 and passes a heated starting mold 22 in a standing position to a supply station 17 · ^; ; \ From here you enter the first forming tool

in a known manner "z" B * with the aid of a swiveling wrench 20. ^w '· Dies® is, however, inevitably omitted if the transfer of the heated external mold takes place directly into the first forming tool. "

Prior to rotation of the rotary unit 11, the two robot units perform the following movements with time overlay:

The first robot unit 1 travels by a defined stroke; The second robot unit 6, on the other hand, likewise drives upward by a defined stroke and pivots the gripper 9 90 ° in order to reduce the transport radius The robotic units thus assume the position shown in FIG. 2. Subsequently, the rotary unit is rotated by 180 °, while maintaining the bent position of both grippers. After this rotation, the first robot unit 1 of the press now stands and the second robot unit 6 face the heating equipment (Fig. 3), and the robots then perform the following movements: the first robot unit 1 pivots the gripper 4 upwards by 90 °, thereby bringing the transported lying parent mold 21 into the vertical position down by a defined stroke and passes the output form to the staging station 17, then the first robot unit 1 moves up again by a defiled stroke and pivots the gripper down by 90 °.
