Definitions

  • the invention relates to a hotplate stacking aid for electric hotplates.
  • Stacking aids of this type which can have different stacking inserts for the structural units to be stacked one above the other and possibly next to one another, generally serve as aids in order to ensure that the stacked structural units stand securely and to keep them at a sufficient distance from one another.

Adjacent adjacent flat shells are expediently connected to one another by their bond in the common pallet plate, so that the stacking columns standing in the area of a pallet plate are directly connected to one another in the associated stacking layer, so that they are directly connected to one another against transverse or tilting forces, in particular, occurring as tensile forces.
  • Superimposed flat shells or pallet plates which can be of the same or different design, are preferably supported against one another completely without contact, essentially only by mediating the hot plates lying between them, although an almost slightly supportive contact of stacked pallet plates in the areas between the flat shells and / or in Edge area of the pallet plates is conceivable, for example in such a way that in each case one pallet plate forms a lid for the adjacent pallet plate and thus the one in between intended hotplates are in a room that is essentially completely closed to the outside and can thus be protected against the ingress of atmospheric moisture.
  • each flat pan is expediently in centering engagement with only a single hotplate, wherein flat shells or hotplates lying one above the other can lie axially aligned with one another over the entire height of the associated stacking column.

  • the side of the pallet plate facing away from the shell openings can be essentially continuously flat, so that the pallet plate has different wall thicknesses and a relatively high rigidity, but it is particularly expedient if the pallet plate is designed to be elastically resiliently flexible in such a way that Moving adjacent flat shells against each other in an articulated manner and resiliently deforming in such a way that they adapt themselves under the stack pressure to ensure constant specific surface pressures in the area of their supporting surfaces.
  • the pallet plates in the case of such a design, for example formed by a deep-drawn plastic plate of approximately 1 mm in thickness, it is also possible in a simple manner to design the pallet plates to be stacked in an interlocking manner so that the associated stacking height multiplies the number of stacked pallet plates by their wall thickness plus the thickness or height of a pallet plate. This means that the pallet plates can be transported in a space-saving manner for reuse after the hot plates have been removed.
  • Carrying pallet provided, which can be formed for example by a so-called. EURO pallet or a pool pallet.

  • a clamping part 42 which is also supported opposite the upper underside of the mounting plate 41 and is adjacent to its elevations around each electric hotplate 2, is formed, which in the area of each hotplate 2 forms a substantially flat-shell-shaped clamping shell covering its underside .
  • the clamping part 42 is also placed fully automatically aligned with the same or another programmable handling device.
  • a fastening bolt 47 in the form of, for example, a cap screw is inserted through a through opening in the bottom of each clamping shell and screwed into a threaded bore in the center pin 48 of the electric hotplate 2, the clamping shell being spring-loaded in this manner that on the one hand their edge rests on one side and the support ring 9 on the other side under resilient tension on the mounting plate 41.
  • the bottom of the clamping shell can have a shape in the area of the fastening bolt 47, the end wall of which is braced against the end face of the central pin 48.
  • Each clamping shell has in the area of the connecting members 33 of the associated electric hotplate 2 a window opening 49 which is continuous over part of its shell bottom and approximately over the entire height of its shell casing, through which the connecting members 33 remain accessible for connection. 8 is gripped through this window opening 49 with a lifter tool 50 and with this tool 50 the connecting members are bent by bending away from the top side of the electric hotplate 2 into the desired connection location transferred.
  • the lifting tool 50 can be actuated fully automatically by the same or a separate handling device.
  • a connector 43 is brought fully automatically through the window opening 49 to the connecting members 33 with the same or a separate handling device in such a way that its freely projecting connecting counter-members 51 come into engagement with the connecting members 33 and two of these members each lie in pairs next to each other, the inherently rigid but resiliently articulated connecting members 33 automatically aligning themselves with guide and threading surfaces which are provided on the counter members 51 or on an insulating body of the connecting piece 43 receiving them.
  • the connector 43 is not designed for the plug connection, but for a spot weld connection with the connecting members 33.
  • a multi-fine-point welding gun 52 is introduced to the pairs of connecting and counter-links fully automatically with a programmable handling device either through the window opening 49 or a separate, further window opening in the clamping shell, this welding gun 52 being one of the number of these pairs has a corresponding number of individual pliers.
  • a transverse movement of the connecting piece 43 can ensure that the connecting and counter-members 33, 51 for the production of the welded connections already abut one another in a punctiform manner. All welded connections for all connecting members 33 are made simultaneously.
  • the connecting counter-members 51 are electrically conductively connected to insulated, inherently rigid connecting lines 44 which connect to the connecting piece 43 or its insulating body on the side remote from the counter-members 51.
  • the Connector 43 is then completely within the clamping shell, while the connecting lines 44 are led out through the window opening.
  • the window opening 49 or the window openings can be covered with a cover or the like. are closed fully automatically except for the passage of the connecting lines 44 with the same or a separate handling device.
  • Any existing earth connection, which can be fastened to the tensioning part 42, and a connection strain relief for the connection piece 42 can also be attached fully automatically using the same or a separate handling device.
  • the mounting plate assembled in the manner described is removed from the assembly table or from the supporting surface 40 using the same or a separate programmable handling device and placed on a stack, so that a further assembly cycle can begin.
  • the training according to the invention is not only for mounting plates made of sheet metal, but also for those made of tempered glass or the like. suitable, as described for example in DE-OS 33 17 624, which is referred to for further details and effects.
  • the pallet plates 10 can have mutually alignable or stacked engagement members 53 in the form of holes, for example, which are provided outside the plate field 26 in the region of their corners in the channel bottom. These engagement members are suitable for the pallets, for example, by inserting rods that reach above the stack height plates 10 to align with each other. However, they can also serve as markings for a sensor of the handling device in order to detect the position of the stack. Furthermore, orientation aids for a search camera or a similar sensor can be attached to the four corners of the plate pallets or to their parts or regions of the stack, which pass on the information for alignment to the robot. These orientation aids are formed in particular by the links 53.
