The front and rear plates 9, 9 are respectively erected vertically, and the front and rear plates 9, 9
This prevents the left and right side plates from bending inward to maintain the shape of the box. Furthermore, this foldable container has cutout recesses 10, 10 formed at the four corners of the upper frame 1 in order to prevent the upper and lower containers from shifting laterally when stacked in either the folded state or the boxed state. , a fitting protrusion 11 corresponding to the cutout recesses 10, 10 at the bottom of the bottom plate 2,
11 is provided protrudingly, and a recess 12 is formed in the middle lower part of the front and rear frame members of the upper frame 1, and a gripping hole 13 is formed in the folded state. It is designed to be easy to grasp.

(Problem that the invention attempts to solve) The foldable container configured in this way is
When stored or transported, they are folded and stacked, but when they are used, they must be assembled into a box. Previously, all of the container assembly work was done manually, resulting in poor work efficiency.

The inventor focused on the above-mentioned inefficiency of manual assembly work and thought of proposing an automatic assembly machine that performs assembly work with high efficiency.

The present invention provides a device for completely box-forming a container in the final step of the assembly work of the automatic assembly machine, and aims to form a plurality of containers at the same time.

(Means for solving the problem) For this purpose, in the present invention, of the two sets of opposing side surfaces, the left and right side panels have a hinge part in the middle part that allows the side plates to be folded in half, and The plate is pivoted at both ends to an upper frame so as to be rotatable inward. A device for assembling a plurality of containers in a folding container assembly machine, in which the plurality of containers are connected together. An operating cylinder is installed downward on the immovable frame on the conveyor to be transferred, and an operating cylinder is fixedly attached to the downward operating rod of the operating cylinder.
The horizontal horizontal rod of the book, each of which is a set of two, the upper end is pivotally supported by the horizontal horizontal rod, and a storage elasticity is given so that it spreads downward, and a plurality of sets each have a roller at the lower end. The present invention is characterized in that the distance between the lower end rods of each assembled box arm in the expanded state is approximately equal to the distance between the front and rear plates of the container.

(Function) This device operates the above-mentioned actuating cylinder downward to move the horizontal horizontal rod when a plurality of pre-boxed containers are transferred in series and sent directly under each box-making arm. and move each box making arm down at the same time. Each of the box-forming arms presses the front and rear plates of the corresponding pre-boxed container in the front-back direction, thereby automatically forming each container.

(Embodiment) The drawings show the device of the present invention as part of an automatic assembly machine for folding containers.

First, the outline of the automatic assembly machine will be explained. First, B shown in FIGS. 3 to 5 is a container separation and supply device, which separates stacked containers by a pair of impellers 15, 15 that rotate synchronously in response to the driving force of a drive source 14.
A' is supported, and by the inward rotation of the impellers 15, 15, the containers A at the lowest stage are successively dropped and fed. and refill stacking container
A'' is put on standby, and when the remaining amount of the stacking container A' becomes low, the replenishing stacking container A'' is sent to the remaining stacking container via the receiving plate 16 that comes in and out.
It is arranged to replenish the supply on A′. Container A fed by this container separation and feeding device is laterally transferred by a conveying device D.

This conveying device D consists of a pair of chains 19 in which push rods 18 having support claw pieces 17 are installed at regular intervals in the middle, a pair of guide bars 20 that support the container A, and a pair of guide bars 20 located at the terminal ends to allow the movement of the chains 19. It has a rapid advance part E consisting of a circulation belt 21 that advances faster than the speed, and the part located below the container separation and supply device B is inclined upward in the traveling direction as shown in FIG. The bar 20 has been lowered. And the support claw piece 17
through the gripping hole 13 (8th
(shown in the figure), the container A is advanced, and when the guide bar 20 is in the lowered position, the container A is preliminarily formed into a box.

C is a container preliminary box making device, and operating rod 2
2, and the downward projecting action of the actuating rod 22 pushes down the front plate 9 of the container A, thereby preliminarily forming the container A. Container A pre-boxed in this way
is rapidly advanced by the rapid advancement portion E, and the support claw piece 17
and drive roller conveyors 24, 25.
sent to the top.

1 and 2 show the container box forming apparatus F of the present invention. In the figure, 26 is a roller conveyor, on which the containers A are conveyed in a vertically connected manner. For this reason, this conveyor 26 is connected to the above-described driving roller conveyor 25, and the container A is pushed by the transporting force of this driving roller conveyor 25. 27 is a fixed frame for the device of the present invention, and the roller conveyor 26 is
The roller conveyor 26 is installed so as to straddle the roller conveyor 26, and guide guides 28, 28 are fixed to the immovable frame 27 along both upper sides of the roller conveyor 26. In the illustrated embodiment, there is shown an apparatus for forming four containers A at the same time. For this purpose, an actuating cylinder 29 is installed facing downward on the upper part of the immovable frame 27, and a horizontal rod 31 is fixed to the lower end of the actuating rod 30, and each container A is mounted on this horizontal rod 31. A pair of box making arms 32 are pivotally supported for this purpose. Each pair of these box-forming arms has a roller 33 at the lower end, and the lower part is inclined in the direction of expanding from side to side, that is, expanding downward in a V-shape, and an elastic force in the expanding direction is applied by the expanding elasticity of the spring 34. It is always positioned facing the transfer area of container A. The distance between the lower ends of these box-making arms 32, 32 in the fully expanded state is made approximately equal to the distance between the front and rear plates 9, 9 of the container.

35, 35 are intermediate supports 36, 36 of the immovable frame 27
Guide rods 37 erected at the left and right positions of the horizontal beam 31 are pushed through by a horizontal beam installed between them, so that the horizontal beam 31 moves up and down while maintaining its horizontal state.

In the device of the present invention described above, the actuating cylinder 29 is adjusted to operate at the same timing every time a fixed number (four in the illustrated embodiment) of containers A are pushed. Of course, when the actuating cylinder 29 is in its inoperative state, the actuating rod 30 is positioned at the retracted position, and each box-forming arm 32 is retracted so as to face the passage area of the container A. Then, when the containers A preliminarily made by the preparatory box making device are connected and sent directly under each pair of box making arms 32, the actuating cylinder 29 is actuated,
The respective box making arms 32 move downward at the same time.

The box-making arm 32 presses the front and rear plates 9, 9 of the corresponding container A, and expands the front and rear plates 9, 9 by the expanding elasticity of the spring 34, thereby completing the box-making process. Then, the post-actuating rod 30 is immediately retracted to return each box-forming arm 32 upward and stand by for the next box-forming operation. The container A thus formed is sent out.

(Effect of the invention) As mentioned above, in the device of the present invention, the downward operating rod of the operating cylinder provided downward on the immovable frame has one
The horizontal rods of the book are fixed, facing the moving area of multiple containers that are transported in a connected manner, and are paired so as to correspond to the front and rear plates of each container, and elastic force in the direction of expansion is applied. The box-making arms are pivoted to the horizontal rods, and the downward movement of the operating rod causes each of the box-making arms to press and expand the front and rear plates of the container. Box work can be done automatically with a simple structure,
Furthermore, it is possible to carry out the box-making work for a plurality of containers at once, and it has the effect of making it possible to perform the box-making work with high efficiency.
