Definitions

  • the invention relates to a casting plant with a Transport device for the molds, in particular Chill molds, to the individual work stations for casting of metals.
  • the invention has for its object a flexible casting plant to propose for casting metals.
  • the casting unit or the manipulator is each arranged on an autonomous mobile unit which is coupled to a control system, so that he or she is responsible for an optimal workflow of the individual Casting required workstations supplied can be a variety in an extremely inexpensive manner of castings are produced at the same time the facility being operated continuously can, because during operation both on the manipulators Casting molds or independent casting units replaced as well as workstations or can be replaced.
  • the required mold movements can be done by the Manipulator or at the casting unit after coupling be carried out by the respective workstation.
  • the casting units or manipulators can expediently be conveyed from transport modules and swivel modules to the individual work stations, buffers and locks on the basis of a track guidance.
  • the manipulators or casting units can also be routed to the work stations on the factory floor and a sensor-controlled steering device by a controller.
  • the control of the manipulator can also directly control the work station approached, the control of the manipulator being programmable in accordance with the required workflow for producing the individual casting specified by the casting mold.
  • At least one of the work stations is advantageously designed as a charging station for an energy store arranged in the manipulator.
  • Further movements of the manipulator 2 can be done by the Transport modules 3 and 4 pivot modules are generated. In addition, additional movements can be made at the individual work stations 5 are executed.
  • the movements of the Mold carrier 11 are carried out hydraulically.
  • a pressure accumulator is provided in the manipulator 2, the special charging stations is charged or recharged.
  • the individual manipulators 2 have a decentralized one electrical manipulator control with battery buffer, all functions of the respective manipulator 2 and the transport and swivel modules 3.4 controls, where the controller is programmable so that a for the individual mold required process sequence is ensured. In addition, it can also at any time by hand on manipulator 2 or wirelessly in the manipulator control be intervened.
  • the individual workstations 5 the currently running Work program and the individual program steps via a screen or color and / or Light symbols are displayed.
  • too video surveillance at the individual workstations be provided.
  • a malfunction indicator and Fault diagnosis system for displaying fault locations and Error causes are provided so that a quick Troubleshooting and high system availability is guaranteed.
  • a cast body is produced using the system shown in FIG. 1 in the following manner: At the swivel module 4 at the point 9.3, a manipulator 2 is equipped with a casting mold 1 and is to be introduced into the square of the casting installation via a lock 41. First, the pivot module 4 is pivoted by 90 ° at the point 9.1 and then the pivot module 4 located at the point 9.3 is pivoted into the square, and the manipulator 2 is moved from the conveyor belt 33 to the work station 5 “spraying” at the point 10.1. Then the pivot module 4 is pivoted back to its starting position at the point 9.3. After the "spraying", the manipulator 2 is moved via the control to the location point 11.1, where temperature control of the casting mold 1 is started. The temperature continues to be at point 11.2.
  • the manipulator 2 arrives at location 12.1, where the manipulator is recharged with energy.
  • the pivot module 4 is pivoted by 90 ° at the point 9.4 to take over the manipulator 2, which then rotates 90 ° to the point 1.3 and 1.2 for further energy recharging and for inserting sand cores.
  • the manipulator 2 then moves to the location point 1.1, where appropriate steel cores can be inserted into the casting mold 1 if necessary.
  • the swivel module 4 rotates back by 90 ° at the point 9.5, so that after the steel cores have been picked up, the manipulator 2 in turn undergoes a change of direction by 90 ° and the mold 1 is blown out and closed at the point 2.1.
  • the manipulator 2 then moves to the location point 13.1 to a buffer 6. From here the manipulator 2 arrives at the location point 4.1, where the casting mold 1 is filled with molten brass. The manipulator 2 then arrives at the location point 13.2 at a buffer position, after which the manipulator 2 then passes through the location point 4.2, another casting furnace, and the steel cores are pulled out of the mold at the location point 6.1. The swivel module 4 then changes the direction by 90 ° to the location point 5.1, from where the manipulator reaches the location point 7.1, where the cast body is ejected from the mold 1 after opening. The manipulator 2 then moves to a buffer position at the point 13.3.
  • the manipulator 2 then moves to the point 8.1, where the mold is subjected to a high-pressure wash.
  • the pivot module 4 is pivoted back at the location point 9.1, so that the manipulator 2 is ready for a new working cycle. If, on the other hand, sufficient castings have been poured, the pivot module 4 is alternatively introduced into the casting square at the point 9.2 and the manipulator 2 with the casting mold is led out via the lock 41.
  • the location points 9.4, 9.6 and 9.7 further swivel modules 4 are arranged, at which manipulators 2 and / or casting molds 1 can be repaired or loaded. In the casting process described above, only the sequence for a manipulator 2 is shown. Of course, several manipulators 2 can circulate one after the other in the square of the casting installation. Different parts can be produced at the same time and different casting methods and molds (sand casting) can be used.
  • a rotary slide module 40 as shown in FIG. 6 of the drawing, can also be arranged in the square of the casting installation.
  • the rotary slide module 40 consists of a rotatable and radially displaceable column on which rails 31 and drivable transport elements for guiding the manipulator 2 are fastened.
  • two transport modules 3 connected in series are connected to one another, so that the manipulators 2 can be moved accordingly.
  • the manipulator 2 is first moved onto the rotary slide module 40.
  • the rotary slide module 40 is then shifted by the distance A and then rotated by the angle B of 90 °. Then the rotary slide module 40 is displaced by a further distance C, so that the rotary slide module 40 is connected to the left transport module 3. The manipulator 2 can now be moved onto the left transport module 3.
  • a redirection of a manipulator 2 to the right Transport module 3 takes place in a similar manner as described above Wise. Just instead of moving on the route C is here a return to Connection to the right transport module 3.
  • the mold with the associated Guide and tensioning elements an independent Form the casting unit.
  • the casting unit can be from the transport modules 3, swivel modules 4 and / or Rotary slide modules 40 of the respective required Workstation 5 are fed.
  • the mold movements are advantageous here from the respective Workstation 5 running.
  • the one used The casting mold can be identified by coding.
  • the work stations 5 are arranged in a square.
  • the workstations also in another formatting, such as as a polygon, etc.
  • the casting process takes place in a circuit via a square, the transport modules 3 and the swivel modules 4 are elevated, and the manipulators 2 above the individual workstations 5 can be moved.
  • the manipulators 2 above the individual workstations 5 can be moved.
  • alternative can also use the manipulators with the mold on the factory floor and a steering device the individual workstations according to an entered Program for the casting process for the individual Start up the mold. Interventions in the sequence program expediently take place wirelessly from one Control center.
