BRIEF SUMMARY
DESCRIPTION
The invention relates to a machine for collecting plastic and paper cups or the like, both of the single-use and of the reusable types.
The machine comprises: an identification device of the type of cup suitable for acceptance by the machine; a dispenser for supplying a coin to a user in return for introduction of an acceptable cup; an inlet for the cups, through which a cup is introduced into the machine; a container, situated internally of the machine, in which the cups are collected once accepted; an internal track connecting the inlet for the cups with the container. Machines of this type are described in European Patents Nos. 94830165.0 and 94830589.1, both belonging to the same Applicant.
The main aim of the present invention to to provide a machine which is constructionally simple and economical and which permits of collecting the cups in the container in such a way as to reduce the empty spaces between one cup and another, and thus of exploiting the container volume more rationally than in known machines.
One advantage of the present invention is that it permits both of less frequent emptying of the container, and of the use of a somewhat smaller container than in known machines.
A further advantage is that the accumulated cups in the container are stacked in such a way as considerably to facilitate their subsequent transport towards a cleaning or destruction point. The invention also obviates hygienic problems which might arise due to the presence of drinks or foods residues left in the cups; this advantage extends to during the subsequent transport of the cups for destruction or cleaning.
The above advantages and more besides are all achieved by the machine of the invention, as it is characterized in the claims that follow, which comprises an operative group, arranged along the transport track and crossed by the transiting cups along the track itself, which operative group composes a stack of cups and locates said stack in a predetermined position internally of a container.
Further characteristics and advantages of the present invention will better emerge from the detailed description that follows, of an embodiment of the invention, illustrated in the form of a non-limiting example in the accompanying drawings, in which:
FIG. 1 shows a schematic view from above of a detail of the machine, comprising the operative group 1;
FIG. 2 is a schematic lateral view from below of FIG. 1, with some parts removed better to evidence others;
FIG. 3 shows, in enlarged scale, a lateral view from the left of a detail of FIG. 1, with a part of the washing device evidenced;
FIGS. 4 and 5 are two vertical elevations of a detail of a second embodiment of the invention, showing some sequential operative positions of the cup exiting from the washing device 3.
The machine comprises an inlet for the cups, through which a cup 6 is introduced into the machine.
The machine further comprises an identification device of the type of cup 6 which the machine will accept, which device, once it has recognised and accepted the type of cup, allows the second work cycle to begin. This identification device is of known type and is disclosed in European Patent Application no. 94830589.1.
A container 2 is predisposed internally of the machine; the cups introduced into the machine are sent to be collected in this container 2. The cup inlet is connected to the container 2 by an internal track in the machine.
The machine further comprises a dispenser which returns a deposit to a user in exchange for a cup once said cup has been identified and accepted by the identification device.
The machine further comprises a washing device for the cups, arranged along said track, which washing device empties the transiting cups by turning them upside down. In the figures the washing device 3 is only partially represented. The washing device 3 comprises two seats 4, each of which houses a cup 6. The seats 4 are mounted on a frame 5 which is rotatable about a horizontal axis. The two seats 4 are arranged on the frame 5 at diametrically oppos
