摘要:
A plant for unloading stacks (5) of thermoformed products from a cage (4) containing stacks (5), which comprises a support structure (2), at least one support plate (3) for a respective cage (4) containing stacks (5), which is mounted for rotation on said support structure (2), drive means (8) to cause said support platen (3) to effect angular movements of a preset amplitude around a horizontal axis, so as to angularly move its respective containing cage (4) between an erect position, in which the stacks (5) of thermoformed products contained therein extend in a substantially vertical direction, and an inclined unloading position, expeller means (12) designed to expel stacks (5) of thermoformed objects from said cage (4) when said support plate (3) is in inclined unloading position, and a conveyer (20) for receiving stacks (4) of thermoformed objects unloaded from said containing cage (4) located downstream of the unloading position of said support plate (3).
摘要:
The present invention relates to a container having a tub body (2; 36) with a bottom (3), a side wall (4), and a lid (5; 37) with top wall (6) and side wall (7). The side walls of both the container and the lid have complementary flanged rims that can fit together by snap engagement with one another. The rim (8) of the body of the container has, in sequence, a first flat flange section (11) extending outwards on the one hand, integral with the side wall (4) of the body of the container and, on the other hand, an inwardly bent section (12) at least partly extending over said flat section (11), an intermediate outwardly convex section (13), a second flat flanged section (14) substantially parallel to the first flat section (11), and a protruding terminal volute-shaped section (15) delimiting an uninterrupted undercut recess (16) with the second flat section (14). The rim (9) of lid (5; 37) has, in sequence, a volute-shaped section (18) being an extension of the side wall (7), a first protruding section (19) designed to engage, in use, with the first flat section (11), an inwardly extending section (20) designed to engage and overlap the inwardly bent section (12), a flat protruding flanged section (21) designed be located at an intermediate area of the outwardly convex section (13), and a flared section (22) ending with a flat flanged section (23) suitable for engaging engage with the undercut recess (16) to form a snap-engaging coupling with a plurality of peripheral uninterrupted sealing areas.

Process and plant for handling and stacking a plurality of thermoformed containers or lids, which comprises the following sequence of phases: obtaining during a thermoforming phase mouldings of lids and containers, having at least three stacking protrusions or spacers, all having the same space arrangement in all the thermoformed products of the same moulding, at least one of the stacking protrusions or spacers of a same thermoformed object being set out in a non specular symmetric way with respect to at least a centre line of the respective container or lid and at a distance from the same centre line of the respective container or lid different from that of the others, arranging one or a moulding of said containers or lids in at least one support template to keep them in order according to the spatial arrangement that they had during the thermoforming phase, turning through a predetermined angle every other object or moulding of objects either containers or lids before or during their transfer to a stacking station, and stacking mouldings of thermoformed containers or lids with alternate mouldings turned through said predetermined angle, so as to obtain stacks of containers or lids, where the stacking protrusions of a container or lid are offset with respect to those of the next container or lid in each stack.

The invention relates to a method of thermoforming and partly cutting thermoforming objects, which comprises intermittently feeding a tape or plate (2) of thermoformable material to a thermoforming press (46); thermoforming and cutting the tape or plate in a mould (48, 50) to obtain at least one thermoformed article (51) surrounded by residual web or waste (57), wherein partial cutting is carried out by means of punch-and-die cutting means (52, 54) and cutting affects the whole outline of each thermoformed object (51) and has at least one discontinuity (55) which results in one or more tiny connection sections or witness beads (58) connecting each thermoformed object (51) to the waste (57).

摘要:
A handling apparatus for groups of thermoformed objects constantly held in a correct axial alignement, which apparatus includes at least one picking up-release head (2) having as many receiving seats extending parallel to one another from said head (2) as are the stacks (4, 4a, 4b) to, be handled, and drive means (7, 19) arranged to move a respective pick up and release head (2) between a stack pick up station (10) and a stack release station (12, 17) of one or more stacks (4) of thermoformed objects and to position it correctly both at the said stack pick up station (10) and at the said stack release station (17, 12), at least one mobile pusher member (21) arranged to be moved between, and parallel to, the said receiving seats in order to engage at the top thereof the stacks (4, 4a, 4b) of thermoformed objects (5) located in each receiving seat, and control drive means (23) for each mobile pusher member (21), thereby following and hold down each stack (4, 4a, 4b) while the same is being released from its respective receiving seat.
