DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to an apparatus for assembling foundry cores to form ready-to-cast core packs. The apparatus comprises a conveying device operating between a removal station of a core shooting machine and a transfer station, a packing assembly having at least one first manipulator and adhesive applicators, and a dip bath, if need be, as well as a subsequent drying oven.
Apparatus of the type described above have been known from practice for years. Only by way of example, reference may be made to DE-PS 35 26 265 and corresponding U.S. Pat. No. 4,744,853. This prior art discloses a core packing machine for a fully automatic assembly of ready-to-cast core packs. In this machine, the cores produced on a core shooting machine are removed therefrom, placed on a pallet, raised therefrom to a core swiveling device, where they are laterally engaged by a clamping device, and provided jointly--in spaced-apart relationship--with adhesive from adhesive applicators. Only thereafter, are the cores moved by lifting devices into a packing assembly and pressed together after retraction of the clamping device.
The apparatus known from DE-PS 35 26 265 is, however, problematic in practice, since it allows to pack only cores produced in a single core shooting machine. In particular, in the case of core packs comprising a very large number of cores or having a very complex structure, it is, however, necessary to produce the individual cores with different tools on different core shooting machines and to assemble same to a core pack. Furthermore, in the known apparatus, the handling of the cores, via the step of applying adhesive, to the pressing is costly and requires a considerable expenditure in apparatus.
It is therefore the object of the present invention to improve and further develop an apparatus for packing cores of the initially described kind, so that it permits a rapid automatic assembly of even complex core packs with the least possible amount of equipment.
SUMMARY OF THE INVENTION
The core assembling apparatus of the present invention accomplishes the foregoing object and comprises a transfer station, and a pair of core shooting machines positioned on opposite sides of the transfer station and so that the core shooting machines define a transverse direction extending therebetween. A pair of pallets are mounted for movement along the transverse direction between respective ones of the core shooting machines and the transfer station, and each pallet is configured for supporting a plurality of side-by-side cores which are aligned in the transverse direction and so that the cores supported on the pair of pallets may be aligned at the transfer station in a side-by-side arrangement extending in the transverse direction. At least one manipulator is provided for grasping the cores while in the side-by-side arrangement at the transfer station and stacking the cores on top of each other, and at least one adhesive applicator is provided for applying adhesive to a surface of at least some of the cores so as to secure together the stacked cores and form an integral core pack. Accordingly, the apparatus of the present invention is designed and constructed such that the packing assembly receives, via the transfer station, cores from at least two core shooting machines. Also, the apparatus of the present invention is designed and constructed such that the one manipulator serves to grasp and deposit or stack the cores, and that the cores may be placed, one on top of the other, on a carriage or running gear.
In accordance with the invention, there are basically two alternatives of an apparatus in accordance with the invention, namely on the one hand with respect to supplying cores from at least two different core shooting machines and, on the other hand, with respect to depositing, or with respect to stacking the cores for purposes of packing.
In accordance with the invention it has thus been recognized that with simple constructional means cores from different core shooting machines may be transp
