Abstract

A corner lap folder for a cardboard tray consists of a lever, whose resistance arm 1 is angular and rotates about a shaft 2 while the power arm 3 is pivoted (4) to the rod 5 of a cylinder 6. It is all supported by a base 7. A folder is provided at each corner for the simultaneous folding of the four laps onto corner reinforcements 12 (13, Fig 5, not shown) to which they are glued. <IMAGE>

Description

1.1. -4 -dl E5 0 1 CORNER LAPS FOLDER FOR CARDBOARD TRAYS The invention
relates to a corner laps folder for cardboard trays.
- Its purpose, just as inferred from the title, is to fold the laps of cardboard trays, which determine a double connection of the sides of the trays with the reipforcemen ts of the angles thereof, by means of glue.
- A certain.type of cardboard_.trays have in the inside of their angles some corner reinforcements whose aim is to be able to pile some trays on top of o-thers.
In some cases said corner reinforcements have the shape of a-triangular column. In others, they are formed by folding the laps, extension of the.front ends, which instead of forming triangular co-lumns are backed.to each other to obtain thickened walls.
Generally, the sides are glued on one surface of said columns or thickenings.
One variant of embodiment of this connection consists of providing the sides with some small laps of the tray, gluing, for the purpose of reinforcing the connection of these sides with the front ends.
This assembly is done by hand, therefore, the manufac turing of - the trays of the type described turns out-to be very expensive.
For the purpose of obtaining the mechanization -of assembly and gluing of the described reinforcement laps, the invention proposes a folder that is incorporated at the final stage of assembly in a box assembly machine in such a way that the four laps of one box are folded and glued automatically and simultaneously.
The folder consists of a lever whose resistance arm shapes an angular head which presses on the lap and folds 2 - -it in a rotation movement, against the triangular column or corner reinforcement of the tray at its inside surface.
The lever has its power arm connected to the rod of 4 pneumatic cylinder, articulated to a support,. on which the rotation-shaft of the lever also'rests.
This lever really constitutes half a clamp for each angle of the tray.
It is mounted in an-arrangement so that all the levers-act simultaneously, one for each angle, in such a waythat in a single operation the four laps, which have been pre- -viously gummed,-of a tray are folded and glued.
For a better understanding of the above, the-present specification is accompanied by some drawings which show the structure_of the folder and in several stages of work.
- Figure 1.- It is a plan view of the folder when it.
is about to start the folding action of one of the corner laps of a tray, which is shown partially, against one triangular reinforcement column.
Figure 2. The same planview-as above in which the folder has effected a rotation movement, moving the lap for its backing against the triangular corner reinforcement column.
Figure 3.-' It is a plan view of the folder when it is about to start the folding action of one of the corner laps of a tray, which is shown partially, against a triangular corner_reinforcement.
Figure 4.- It represents the same plan view of the previous figure, seeing the folder in action, collapsing the lap against the triangular corner-reinforcement.- Figure 5.- It shows the plan view of the folde2 inthe position of starting to fold one lap against the inner part of a flat corner reinforcement.
Figure 6.- previous figure, It represents the sameplan view of the in which the folder has moved the lap, 1 1 until taking it against the inside of the corner reinforcement. In this. specific case the shape of the head of the holder has undergone a modification so' that it adapts to the shaping of the -reinforcemeh.t.
5. Figure 7.- 'It repre'sents a perspective view of a folder acting against one of the corners of a tray, which is also shown complete in perspective. In the corne'rs opposite the ones to which the folder is acting, there are the laps already folded. The folder itself is shown-in 10- the foldinq-acti. on- As is inferred from the drawings, the folder consists of a lever, whose- resistance arm (1)-consists_of-an.angular,body which rotates resting.on shaft (2), while the power arm (3) is articulated by the shaft (4) to the -rod (3) of a pneumatic cylinder (6.) The unit is-supported by a base (7) upon which the _shafts (2) and (8) of the pneumatic cylinder rest.
Each one-of these levers form an attack lip (9) whereby they act against the laps (10) of the-sides (11). of the tray, in such a way that it collapses them and backs against the corner reinforcements, either of a triangular shape (12) like the ones shown in figures 1, - 2, 3 and 4, or else of double wall (figures 5 and 6.) In this last case, the attack lip (9) of the lever is supplemented by a triangular head (14) which obviously can have a different shape, depending on the corner reinforcement.
In accordance with what has been described, it is -30 understood that a_folder will operate in each tray angle.

Claims (4)

1 CLAIMS
1.- Corner laps folder for cardboard trays, characterized by consisting of-one lever-whose resistance arm (l)-is formed by an angular head which rotates resting on shft (2), while the power arm (3) is articulated by a shaft (4) to the rod (5) of a pneumatic cylinder (6); this all arranged horizontally upon a support (7) on which- the shafts (2) of the lever and (8) of the end of the cylinder in such a way that the rotatioh movement:of- the angular head W_ moves the corresponaing lap (10) of the sides of the- tray (12) backing them against the corner reinforcement of the tray itself, to which it is glued.
2.-..Corner'laps folder for-cardboard trays, in ac- cordance with claim 1, characterized by-the arrangement_ of a folder unit, for each angle of the tray, which are operated simultaneou.ly._
3.- Corner laps folder for cardboard tr ays, in accordanc,e with_claims 1 and 2, characterized because the 20- _attack lip 0) of the angular head (1) of the rotating lever is- supplemented by another head (14), shaped depending on the type of angular reinforcement of the tray.
4.- A corner laps folder subst-aintially as hereinbefore described with reference to the 'accompanying dra.wings.
