DESCRIPTION:
BRIEF SUMMARY
The invention relates to a method of handling round flat substantially identical ends for tins wherein the ends are provided in the form of a plurality of elongated stacks of ends, each stack comprising a plurality of separate ends in abutting relationship and surrounded by a sheet of material such as paper.
When, in particular in the supply of the ends to the transport member, a gap is formed between the transported ends, they may fall over due to lack of support by preceding or following ends. This involves a disturbance in the transport of the ends.
The invention has for its object to carry out the method in a manner such that the risk of disturbances is reduced. For this purpose the invention provides the method and the device described in claims 1 and 2 respectively. The device embodying the invention preferably has one or more characteristics defined in the further claims in order to provide a particularly effective device for feeding a closing machine without interruption and with the required supply rate, in which machine the tins are provided with ends.
In general the invention provides a device combining a high transport rate with high reliability i.e. a very low sensitivity to disturbance.
To give a concrete idea reference is made to a known device for transporting ends serving to close preservation tins. It is capable of transporting at the most about 500 ends a minute. In practice it is found that this device is not sufficiently reliable so that constant supervision by the staff is necessary in order to avoid stagnation in the production.
The device according to the invention is capable of transporting about 1000 ends a minute with a considerably improved reliability.
The invention will now be described more fully with reference to the accompanying drawings showing a few embodiments. The drawings show in:
FIG. 1 a drastically simplified, schematic perspective view of a complex machine comprising a device embodying the invention,
FIG. 2 a sectional view II--II in FIG. 1,
FIG. 3 a sectional view III--III in FIG. 1,
FIG. 4 a perspective view of a further embodiment of a combined machine in accordance with the invention,
FIG. 5 a further detailed, fragmentary, perspective view of detail V of FIG. 4 on an enlarged scale,
FIG. 6 a schematic plan view of the detail of FIG. 5,
FIG. 7 a cross-sectional view VII--VII of FIG. 5,
FIG. 8 a cross-sectional view VIII--VIII in FIG. 5,
FIG. 9 on an enlarged scale detail IX of FIG. 1,
FIG. 10 a cross-sectional view of a stack supply device of a further device embodying the invention,
FIG. 11 on an enlarged scale the stack unpacking device of FIG. 10,
FIGS. 12 to 14 and 16 to 19 fragmentary longitudinal views of a stack supply device to be arranged at the inlet end of the transport device embodying the invention in consecutive operational positions,
FIG. 15 a cross-sectional view of the stack unpacking device of FIG. 10 to be arranged at the input end of the transport device embodying the invention,
FIGS. 20 and 21 schematic views of the inlet end of the transport device of FIG. 1 embodying the invention in two different positions,
FIG. 22 a fragmentary side elevation of an inlet end of a further transport device embodying the invention, with which the stack supply device of FIGS. 10 to 19 can be connected,
FIGS. 23 and 24 schematic sectional views taken on the lines XXIII--XXIII and XIV--XIV respectively in FIG. 22 and
FIG. 25 a preferred variant of the sectional view of FIG. 23 on an enlarged scale.
FIG. 1 shows a combined machine 1 for introducing stacks 4 of ends 3 to the closing devices 2, which comprise means for shutting tins by a supplied end 3.
The stacks 4 of ends 3 are successively supplied in a stack supply device 89 in the direction of the arrow 5 by means not shown in FIG. 1 to a guide chute 6 to which is adjoined a reciprocatory pestle 7 for supplying a stack 4 of ends 3 alternatively to transport devices 8 and 9 according to the invention. For this alternating supply the inlet ends of the transport devices 8, 9 are coupled and movable in the dire
