Definitions

  • the invention relates to a pallet for storing any parts in the foundry technology, in particular for storing cores, wherein for the production of ready-to-cast masks or core packages in core shooters, fired and solidified cores are removed from the core shooters, optionally processed and on the pallet carried by a conveyor to which Core package to be completed.
  • the present invention relates to the field of foundry technology.
  • foundry cores or molds are usually produced in separate parts, brought together and connected to one another to form a casting mold or a core package.
  • These core packages are then filled with molten metal to produce, for example, a metallic workpiece, with the core packages to be filled with molten metal passing through the production line in series in series production.
  • the core shooters that shoot the required cores are arranged in a row - linearly, whereby the shot cores, which have been removed from the core shooter and possibly processed, are placed on an assembly line rigidly coupling the core shooters or on pallets of the row carried by the assembly line after being filed.
  • the core package is completed from core shooter to core shooter, namely in the mostly rigidly predetermined order of their arrangement, which usually corresponds exactly to the order in which the cores are packaged.
  • the present invention is based on the object of taking a measure to increase the flexibility of the manufacturing facility while reducing the storage of different types of pallets, the manufacturing facility itself being intended to remain unchanged.
  • the generic pallet is designed as a reversible pallet with two storage sides.
  • the flexibility of the production device can be increased and the storage relating to different pallets can be reduced by using a single pallet for storing two different parts or cores.
  • the pallet is designed as a reversible pallet, the pallet having two mutually independent storage sides for storing different parts or cores.
  • the pallet is positioned with one or the other storage side up on the conveyor, so that the need for different pallets - due to the two differently designed storage sides - is halved.
  • each of the two storage sides has an at least partially designed support for protecting the parts.
  • This edition can be applied interchangeably to the respective storage side.
  • the pad is made of a soft rubber, foam rubber being particularly suitable here.
  • each storage side can be assigned a special receptacle for different parts.
  • the receptacle is adapted to the contour of the parts or even has appropriately adapted receptacle elements. These receiving elements can partially engage in recesses in the part to be put down and thereby virtually fix the part in its position.
  • a pallet can be adapted to respective parts or cores.
  • the receptacle itself and / or the receptacle elements could thereby be tiltable and pivotable or exchangeable as a whole or even with individual receptacle elements.
  • Arbitrary arrangements of differently dimensioned or designed receiving elements can thus be generated in accordance with the parts to be positioned.
  • the receptacle and thus also the receptacle elements forming the receptacle could be designed as a teaching and at the same time serve to deburr the parts to be placed thereon. In this case, it could be necessary to provide a special compressed air device for cleaning separated particles or for removing core sand residues, in order to ensure that the parts rest correctly on the pallet.
  • each storage side of the pallet has a double function.
  • This double function can be realized in a particularly advantageous manner in that the pallet is divided into the two areas and that the two areas of the pallet can be handled and connected independently of one another, this being true for both storage sides.
  • the pallets are carried by the conveyor or are placed on the conveyor.
  • the pallet could have lateral running edges in the form of strips projecting downwards and upwards, so that the respectively downward-directed receptacle does not come into contact with the conveyor device. Lateral rolled edges could also be provided instead of lateral running edges.
  • the pallet is provided with any lateral boundaries that protrude above the receiving elements, which serve on the one hand to position the pallet and on the other hand to protect the downward-facing receptacle or the corresponding receiving elements.
  • the pallet is made of steel. Adequate corrosion protection would be ensured in the case of a construction made of stainless steel.
  • the pallet according to the invention has the advantage that it can be used at least for storing two different parts or cores, namely because of the two different receptacles. Consequently, it is necessary to provide a special device for handling the pallets, namely to selectively position one or the other storage side upwards.
  • turning stations are provided in a very particularly advantageous manner in the area of the conveying device, where the pallet can be turned over, for example by means of a manipulator or a special tilting and turning device. To this extent, it is advisable to provide the turning station exactly where pallets are discharged from the conveyor or other pallets are fed to the conveyor.
  • Such a pallet change is also for cleaning or maintenance of the Pallets, but also required for the exchange of the pallet type, the need for exchange and thus also the storage of different pallets being reduced by half due to the design as a reversible pallet compared to conventional production facilities.
  • Fig. 1 is a schematic side view of a reversible pallet
  • Fig. 2 is a schematic plan view of the reversible pallet from Fig. 1, where connection options of different receiving elements are provided.
  • the two figures show a pallet for the storage of any parts in the foundry technology, specifically for the storage of cores, whereby for the production of ready-to-cast masks or core packages in core casting machines, shot and solidified cores are removed from the core shooting machines, possibly processed and on the pallet carried by a conveyor to be completed to the core package.
  • a representation of the cores on the one hand and the conveyor device on the other hand is omitted here.
  • the pallet is designed as a reversible pallet 1 with two storage sides 2, 3.
  • Each of the storage pages 2, 3 has a support 4 to protect the parts to be placed thereon, which is a soft rubber.
  • Figures 1 and 2 show together that each storage side 2, 3 is assigned a receptacle 5 for different parts or cores.
  • the receptacle 5 is adapted to the contour of the parts or cores and has corresponding receptacle elements 6.
  • FIG. 2 it is indicated that the position of the receptacle 5 or the receptacle elements 6 can be changed or can be exchanged as a whole, free positioning positions 7 being indicated there.
  • the receptacle 5 is designed as a teaching, which teaching can also serve for deburring the parts in addition to the actual function as a receiving 5.
  • the reversible pallet 1 according to the invention is further advantageously equipped with lateral running edges 8 which, in the exemplary embodiment selected here, serve to rest on the conveyor device not shown in the figures. In this respect, the downward-facing receiving elements 6 are protected against unwanted contact of the conveyor.
  • the pallet is made of stainless steel in the embodiment chosen here.

Abstract

La présente invention concerne une palette (1) conçue pour y déposer toutes sortes de pièces en fonderie, notamment des noyaux. Pour la fabrication de masques ou de paquets de noyaux de coulée, des noyaux tirés et solidifiés dans des machines à tirer les noyaux sont retirés de celles-ci, voire traités et acheminés sur la palette portée par le système transporteur, à seule fin de compléter le paquet de noyaux. La palette selon l'invention est conçue comme palette réversible (1) à deux faces de dépôt (2, 3), de manière à rendre l'usage des palettes plus flexible et à réduire la diversité des types de palette à stocker.
