Definitions

  • the invention relates to a method and a device for inserting cores into the molding boxes of a box-molding plant.
  • Box-forming plants are used in foundries and serve for the production of molded parts from metallic materials in the casting process.
  • the outer contour of the molded parts is determined by the inner contour of the respective molding box. If the castings have cavities, it is necessary to insert cores to image the cavities of the castings.
  • the cores are usually made of compacted sand and are manually or mechanically stored in the molding box.
  • the invention is therefore based on the object to provide a method and a device suitable for carrying out the method, with which or a dropping of cores in mold boxes under reduced effort is possible.
  • the loading of the holding device with the at least one core of storage facilities - so-called core shelves - takes place directly on the robot.
  • the supply of cores via transport devices is therefore completely eliminated. Expenses for the latter are therefore unnecessary.
  • only one core die is required, namely that of the holding device itself. It is thus also possible to dispense with a large number of edge dies, which are necessary in the prior art.
  • the holding device is - activated with pneumatic negative pressure.
  • the embodiment of the method according to the invention sient that the holding device is initially facing the operator for inserting the at least one core and is pivoted after activation about an approximately horizontal axis by an angle greater than 90 ° so that the at least one core facing down, in other words, hangs.
  • the at least one core can then be inserted by the operator by a displacement with a downward movement component in the core die of the holding device, which has the advantage that the core already in the holding device remains due to gravity and the loading process of the operator in a pleasant Posture can be observed. Only then is the activation of the holding device and the required pivoting of the holding device such that the at least one core can be delivered down to the molding box.
  • the device for carrying out the method according to the invention comprises a robot arranged next to or above the box molding machine and a holding device for at least one core which can be moved between the robot by means of the robot Insertion position, in which the at least one core is inserted by the operator in the holding device, and the dispensing position, in which the at least one core is delivered to at least one molding box, is displaced.
  • the holding device may be formed mechanically acting, wherein their operation, for example, can also be done mechanically, hydraulically, electrically or pneumatically. It is preferably designed as a pneumatically actuated suction pad. If, as is particularly preferred, it is arranged pivotably about an approximately horizontal axis on the robot, the insertion of the at least one core-as already described above-can take place in a particularly simple manner by the operating personnel.
  • guide means are preferably provided for positioning the holding device during the dispensing operation of the at least one core on the at least one molding box.
  • a quick-change system is preferably provided, via which the holding device on or can be decoupled from the robot. It is understood that the quick-change system can be designed both manually, as well as automatically operable.
  • the robot is designed as articulated-arm robot.
  • the designated in the drawing with 100 box molding plant comprises a production line 1, with the molding boxes 2 in the direction of arrow P of a core insertion station 3 are supplied and transported away from this.
  • the Kerneinlegestation 3 comprises a designated as a whole with 4 device for inserting not shown in the drawing cores in the molding boxes 2, which has a articulated arm robot 5.
  • the latter carries at the free end 6 of its arm 7, a holding device 8, which is configured in the illustrated embodiment as a pneumatically operated suction gripper.
  • the generation of the vacuum required for its operation is an aggregate 9, which is operatively connected via a vacuum line 10 to the holding device 8.
  • Fig. 2 various positions of the articulated arm robot 5 are shown, with reference to which the operation of the device and the procedure to be explained.
  • the position indicated by I is a rest position. In this access to the mold box 2 is released, so that the same can be done manually with a core.
  • the implementation of a method step with the robot according to the invention begins with the position indicated by II.
  • the holding device 8 by pivoting about a horizontal axis A with its Kernauf- or Kernabgabeseite 11 operator 12 faces that inserts manually not shown in the drawing cores of core shelves 13 in the holding device 8.
  • the unit 9 is activated to generate the negative pressure or the vacuum line 10 by a not in the drawing shown valve assembly with running unit 9 operatively connected to the holding device 8 and then displaced by pivoting and bending of the arm 7 of the bending robot 8 and by pivoting the holding device 8 about the axis A in the position III, to there by decoupling the negative pressure from the holding device 8 to deliver the core to the molding box 2.
  • For positioning serve on the holding device 8 provided guide pins 14, which together with provided on the forming boxes 2 guide bushings 15 guide means 16 form.
  • the core insertion station 3 is surrounded by protective fences 17.
  • the safeguarding of the insertion of the cores in the holding device 8 betechnikstelligenden operating personnel 12 is a light barrier assembly 18th
  • the respective operating state of the device is displayed by means of a signal light 19.
  • the holding device 8 is mounted on the arm 7 via a quick-change system, so that holding devices 8 with core matrices (not shown in the drawing, adapted to different cores) can be mounted in a simple manner for equipping molding boxes 2 with different cores.
