Definitions
- ABSTRACT A machine for forming trays and the like, which com- 7 A prises a'device for removing blank sheets of cardboard from a magazine, another device for inserting the sheets individually into a hopper for forming the sides, a further device for folding the sides inwardly, doubling the thickness of the cardboard, and a still further device to compress the folds inside the container folding tray.
- FIG. 1a is a side elevation of FIG. 1;
- FIG. 2a is a plan view of a blank from which the finished tray is produced.
- FIG. 4 is a top plan view of FIG. 3a
- FIG. 5 is an elevational view of a longitudinal lateral folder
- FIG. 6 is a view of FIG. 5 in another position
- FIG. 7 is an elevational view of the operating mechanism for several units
- FIG. 8 is a side elevational view of FIG. 7;
- FIG. 9 is a plan view of the final folding stage
- FIG. 10 is a side view of a portion of FIG. 9.
- FIGS. 11-14 are elevational views of a transverse internal folder in different positions respectively.
- the production of the containers is effected by the machine, commencing with a blank 2, as seen in FIG. 2, in such a way that after a sequence of operations has been carried out, the sides and ends are formed with double thickness folds. At no time does anything have to be done manually and the finished container is proucked in a fully automatic fashion.
- the object of the invention is to enable an automatic machine of the aforementioned type to be built and to be constituted by a combination of a plurality of operational units, suitably synchronized one with the other; each .unit being responsible for one particular stage in the production; this ensemble allowing the containers to be continuously and rhythmically produced.
- FIG. I provides a general view of the machine, seen from one side, wherein the following can be seen: a Geneva wheel 3 for providing an intermittent motion, operated by acontinuously variable speed drive 4 (FIG. 3) with a handwheel 5 to regulate the speed; a double chain drive 6 with articulated and interchangeable container forming trays 7, the sizes of which vary according to the dimensions of the containers to be formed, made by the Geneva drive mechanism 3 to undergo displacements or constant steps P for each working cycle.
- On shaft 8 of the drive of the Geneva wheel which turns the machine are mounted the cams 9 and the microswitches 10 belonging to all the electrovalves used to operate the pneumatic cylinders distributed throughout the machine, mention of which will be made in more detail later on in this text.
- FIG. 2a shows the magazine 1 for the blanks with the guide walls 12 and a terminal member 13 provided with micrometer adjustment which makes it possible for one blank to be removed at a time.
- the cardboard blanks rest on the bottom of special lattice supports 14 (FIG. 4) andare disposed alternately with respect to the teeth 15 on the bars 16 mounted on the chains 17.
- the plate 24, operated by the pneumatic cylinder 25 tripped by the microswitch 23, is lowered and pushes the blank inside the hopper 26 until it reaches the bottom of the container forming tray 7. Whilethe blankis being pushed down'inside the hopper, the tray is folded along the score lines into a box shape and, due to its insertion in the container forming tray 7 and to the fixed walls 27, it remains in this condition.
- the hopper 26 has a special open shape through which the tall flaps of the smaller side of the tray can pass, it is possible, unlike that which is the case with other similar types, to quickly change from one size to another.
- the tray is transferred along the axis of the D-E units (FIG. 4).
- the longitudinal lateral foldef D is duplicated on the two sides (FIG. 5) and its operation is as follows: Through the fork 29 and the shaft 30, the cylinder 28 (FIG. 4) moves the folders 31 which, as can be seen from FIG. 5, are initially raised since the roller of the lever 32, to which they are connected, is pulled by the spring 33 so that it rests on the lower part of the fixed cam 34. As it moves, however, the roller of the lever 32 moves up on the profile of the cam 34, causing the folder 31 to be lowered.
- FIG. 5 shows the folders in their non operative position, on the opposite side the folders 31 are visible after they have performed their operation.
- This operation is carried out with a combined forward thrust and top to bottom rotation.
- the longitudiv nal internal folders E which are operated by the pneumatic cylinder 35 (FIG. 5) and slide along the guides 36, are lowered into the position shown in FIG. 6 and further fold the flaps 37 while the folders 31 and 31 return to their non-operative position as shown in FIG. 5.
- the internal folders are made to expand by the pneumatic cylinder 38 and this permits the double folders 39 to undergo a travel x so that the tabs 40 (FIG. 2) are put inside their respective grooves 41.
- FIG. 7 shows the operating mechanism used for the E-G units.
- the pneumatic cylinder 42 connected with a spiral pipe 43, operates a rack 44, the far extremity of which has mounted on it either the double folder 39 (FIG. 8) of the unit E or the triple folder 45 (unit C).
- the movement of the rack '44 is split by means of the double spool 46 (FIGS. 7 8: 8), on to the rack 47, the lower extremity of which can have mounted on it either the part 39 or the part 45.
- the action of the cylinder 42 generates two expansion paths for the internal fold and these are identical and symmetrical. It should be noted that, as indicated in FIGS. 7 & 7a), the displacements y towards the outside or towards the inside, make the necessary variations in sizes possible.
- FIG. 9 provides a planview of the final folding stage I in which the operations are as follows: the shafts 48 driven by the cylinders 49 through the racks 50 and the spools 51 (FIG. 10) have mounted on them the rotary folders 52 which, as can be seen from F IG. 11, are horizontal at the time they arrive at the tray. The unit G internal folders is also raised. In FIG. 12, the folders 52 have rotated through 90 and have commenced folding the inside of the flaps 53. At this juncture, the units F-E-G which are all together on one common frame (FIG. 11) which, operated by the pneumatic cylinder 54 (FIG. 12), slides along the guides 55-56 (FIG. 9), is lowered and this contributes in completing the folding of the flaps 53. During the transition from FIG. 12 to FIG. 13, the folders 52 have returned to their original position whilst the triple folders 45 have further plunged the flaps 53.
