DETAILED DESCRIPTION OF THE INVENTION

[0026] The following description is provided, so as to enable any person skilled in the art to make use of the invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, are adapted to remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide a machine for assembling a container accommodating perishable goods and a method of doing the same.

[0027] Reference is now made to FIG. 1, presenting a general view of assembling machine 200. The aforesaid machine comprises bag placing module 250 and bag securing module 260. An operation principle of bag placing module 250 is on the market (for example, Pattyn poly bag inserter). Operation of bag securing module 260 will be described in detail below. Machine 200 includes infeed conveyor 210 and outfeed conveyor 220. Belts of conveyers 210 and 220 move in directions indicated by arrows 270 and 280, respectively. Bags (not shown) are secured to frames 10. According to one embodiment of the present invention, frames 10 are releasably placed onto mountings 12 to be transported by conveyors 210 and 220. The aforesaid conveyors are cyclically interconnected by pushers 330 and 340 which push frames 10 from one conveyor to another during the machine operation. Unequipped frame 10 is placed onto conveyor 210 and pushed by pusher 230 to conveyor 220, which conveys frame 10 to bag placing module 250. After placing the bag (not shown), frame 10 is moved to bag securing module 260 where the bag is thermally welded to frame 10. Other technologies are also in the scope of the present invention. The frame equipped with the bag is indicated by numeral 10a.

[0028] Reference is now made to FIGS. 2 and 3, presenting bag securing means. The principle of operation is in the following. When s main portion of the bag is placed into frame 10 and a rim portion of the bag is everted around frame 10, internal member 20 is inserted into the main portion of the bag, while external members 30, 40, 50 and 60 are outside of the bag. Internal member 20 is carried by bar 27 and provided with heatable body (effector) 25. Similarly, external members 30, 40, 50 and 60 have heatable bodies (effectors) 35, 45, 55 and 65 (respectfully).

[0029] As seen in FIG. 3, the internal member is reciprocatively movable between positions 20a (standby position) and 20 (working position) in the vertical direction. External members are reciprocatively movable between positions 30a-30, 40a-40, 50a-50 and 60a-60 in the horizontal direction.

[0030] In the working position, effectors press and weld the rim and main portion of the bag to each other.

[0031] Reference is now made to FIG. 4, presenting an operation of securing the bag having main portion 100 and rim portion 110 to frame 10. As disclosed above, rim portion 110 is everted around frame 10. In FIG. 4, external members 30 and 40 with the corresponding effectors (not shown) and internal member 20 with effectors 25 press rim portion 110 and main portion 100 to each other and form weld lines 120 and 130. After securing the bag to the frame, a ready container is removed by the conveyor from the bag securing module.
