6 Claims, 7 Drawing Figures ilh MACHINE FOR THE AUTOMATIC FORMATION AND INSERTKON OF CONTAINER PARTITIONS The present invention relates to a machine for auto matically manufacturing partition baffles forming beehive bodies adapted to separate various articles contained within a box or container and for contemporaneously introducing said beehive bodies into the respective boxes or containers.
At present, in the packing industry, the beehive separation bodies (usually made of corrugated cardboard) used for separating various articles (in particular breakable ones such as bottles and the like) contained in a box, case or container are separately manufactured by special machines and then manually inserted into the corresponding boxes.
This manually performed operation requires considerable time, which results in an increase of the final packing costs.
The machine according to the present invention eliminates this inconvenience since it permits the manufacture of the beehive" body with the simultaneous introduction of same into the respective box or case in a completely mechanized and automatic manner without any need for further manipulation.
The machine in question utilizes the beehive baffle bodies according to US. Pat. application Ser. No. 160,424 of the same applicant, said beehive bodies comprisin each a horizontal element constituted by a flat elongated strip adapted bent in a U-shape and having at least one pair of longitudinal aligned and spaced slots and at least a vertical insert element adapted to be perpendicularly inserted into the pair slots of said first element.
The machine of the invention is characterized by:
a. a first magazine having the strip elements stacked therein in horizontal alignment; a horizontal pushing means suited to push the lowest horizontal element of the pile into conveying members; a bending platform suited to receive said horizontal element conveyed by the above mentioned conveying members; and registering means forming part of the bending platform to exactly define the entering position of the horizontal element,
b. at least a second magazine containing the vertical insert elements placed side by side, said magazine being placed above the bending platform; a vertical pusher associated with each second magazine and suited to push an insert element down into conveying and accelerating members which, while holding said vertical element in exact vertical position, throw it into the pair elongated slots of the horizontal strip located on the bending table, and
c. conveying means suited to bring each empty box below said bending platform to hold the same stationary while the insertion of the beehive body takes place and to move it on, once the beehive body has been completely inserted, the motion of the various members being synchronized with each other.
In the accompanying drawings:
FIG. 1 is a view of the horizontal strip element adapted to be U-bent, thereby allowing to manufacture a beehive" body with six compartments.
FIG. 2 is a view of the vertical element adapted to be inserted into the pair of elongated slots of the horizontal element.
FIG. 3 shows the beginning of the insertion phase of the two elements into the box.
FIG. 4 shows the end of the insertion phase of the two elements into the box to complete the beehive" body.
FIG. 5 shows a plan view of the boxcompleted with a beehive body placed thereinto.
FIG. 6 is a diagrammatic lateral view of the machine according to the invention for insertion of the beehive bodies obtained with the strips 1 and insert element 2 illustrated in the preceding figures.
FIG. 7 is a front view of the machine illustrated in FIG. 6.
With reference to FIGS. 1 to 5; each horizontal element illustrated in FIG. 1 is constituted by a flat elongated strip comprising a central portion 1 and the lateral wing portions 1 and 1" adapted to be U-bent as indicated in FIGS. 3 and 4.
Said lateral wing portions are provided with a pair of coaxially elongated slots 3 and 4 adapted to receive the vertical element 2 illustrated in FIG. 2.
The insertion operation takes place by disposing the horizontal element ll, 1, 1" on the bending Table 17 (FIG. 6) of the machine and by inserting the element 2 vertically into the slots 3, 4, thereby gradually determining the bending of the elements 1, 1, 1 into a U- shape as indicated in the FIGS. 3 and 4, while it is being introduced into the box 5 below.
At the end of the operation, the box is completed with a beehive" body as shown in the plan view of FIG. 5.
The machine permitting the automatic manufacture of the beehive body and the insertion of the same into the respective box or container comprises:
a first magazine 10 having the strip elements 1 piled therein in horizontal alignment; a horizontal pusher 13, 14 comprising a blade 13 pushed by piston, sliding within a pneumatic or hydraulic cylinder 14 and operable to push the lowest horizontal element of the pile into the conveying means. This conveying means is constituted by belts 15 and 16 which convey the unfolded strip element to the bending Table 17. Registering means 18 adapted to ensure the perfect positioning of the strip on the table.
Above the table, there is provided a second magazine 19 containing the vertical insert elements 2 and having mounted thereabove a pusher comprising the vertical blade 22 pushed downward by a piston sliding within the pneumatic cylinder 23. The blade is disposed so as to feed the vertical element emerging from the forwardmost end of the magazine into and between the pair of accelerating conveying belts 26, 26' actuated by rollers 24, 25. The insert element is thus subjected to acceleration in order to throw it with a certain impact against the strip element 1 so as to start, keep on and finally complete the formation of the beehive body into the box 5 below, as illustrated in FIGS. 3 and 4.
The bending table 17, in case of a beehive combination with six compartments, comprises 4 wings portions 17a, 17b, 17c, 17d (this last wing portion not being shown in the drawings). The front wing portion 17a, 17c and the back wing portion 17b, 17d (FIG. 7) are spaced from each other at a distance therebetween corresponding to at least the width of the central section 1 (FIG. 1) of the horizontal strip, while the lateral wing portion 17a, 17b (FIG. 6) are spaced at a distance corresponding at least to the thickness of the vertical strip 2.
The machine is completed by a conveying belt 28 (H6. 7)' adapted to transport each bolt 5, to keep it stationary below the bending table 17 during the time required for insertion of the beehive combination, and finally to move it on so that the successive box may take its place.
The belt 28 can also keep moving continuously while a stop element holds the box stationary during the insertion of the beehive combination, in this case there being a relative motion between the bottom of the box and the belt 28.
All the movements of the various members constituting the machine are synchronized with each other.
As it clearly appears from the above illustrations, the formation of the beehive" body and its insertion into the box takes place completely automatically with a minimal working time, which favorably affects the production cycle and packing costs.
Should the horizontal strip 1 be provided with a plurality of slot pairs 3-4, to form beehive bodies having for instance nine, 12 or more compartments instead of the six illustrated, there will be obviously provided more vertical pushers 22, 23 and more accelerating conveying means 26-26, one for each insert element 1. in this case the bending table 17 is subdivided to a larger number of parts.
The shape of the horizontal and of the vertical elements constituting the beehive.body as well as the shape of the various components of the specified machine may vary in compliance with the appending claims without departing from the spirit of the present invention.
