[Technical field to which the invention belongs]

 The present invention is a container assembly in a folding container assembling machine that automatically assembles a plurality of folding containers that are stacked in a flat folded state and separately supplied into a box. It relates to the device.

[0002]

[Prior art]

 Folding containers are well known, and they are used for many purposes because they can be easily stacked or stacked by stacking them in a flat plate shape. Conventionally, this folding container is used. At that time, it was used by assembling each of the stacks manually, one by one, and then assembling them into a box. Assembling devices have been developed, and those disclosed in JP-B-58-55055, JP-A-62-287826 and JP-A-63-137703 are known.

In the publication of Japanese Patent Publication No. 58-55055 mentioned above, either one of the front and rear plates is pushed down by an actuating rod to be rotated during the transportation of the separated and fed container to make a preliminary box. It is described that box making is completed by rotating the box making arm from the inside to the outside.

Further, in Japanese Unexamined Patent Publication No. 62-287826, a holding body for detachably holding an upper frame of a container holds the upper frame, and a holding body elevating device for raising and lowering this holding body holds the holding body. When the box is in the raised position, the box-making arm elevating device raises and lowers a pair of box-making arms that face each other so as to correspond to the front and rear plates of the container. It is described that the box making is completed by doing this.

In Japanese Utility Model Laid-Open No. 63-137703, a machine frame is provided with a holding body that moves up and down via an endless chain, and a hook provided on the holding body holds the upper frame portion of the container. It is described that the box making is completed by abutting the lower ends of the push-down parts provided on the upper part of the machine frame against the front and rear plates of the container to push and spread them.

[0006]

[Problems to be solved by the invention]

 However, when the foldable container is used as a box as in the past, the supply intervals are irregular because the containers are assembled by hand after they are taken out one by one from the stacked ones. Was bad.

Therefore, a device has been devised for automatically assembling the stacked containers, which are separately supplied one by one, as described in the prior art, into a box body. Among the devices described in the prior art, According to Japanese Patent Publication No. 58-55055, a foldable container can be automatically assembled, but since this device can be assembled while moving the container in the horizontal direction, the entire device becomes large in size. There is a problem that the place where the box can be installed is limited, and the pre-made box is returned to its original folded state during transportation to the box making device, making it impossible to make the box. .

In Japanese Patent Application Laid-Open No. 62-287826, a folding container can be automatically assembled, but since a prime mover using pneumatic pressure or the like is used for all the operations of the device, a device for activating the prime mover. However, there is a problem in that the device becomes large and complicated because it also has a device for controlling them.

According to Japanese Utility Model Laid-Open No. 63-137703, a folding container can be automatically assembled, but if the separately supplied container is not conveyed to an appropriate position, the upper frame of the container will be recessed. Since the upper frame of the container cannot be pulled up without being able to securely hook it with the hook provided on the holder, it cannot be boxed in the box, and each mechanism that constitutes the device is minute and Due to its complexity, there was the problem that failures were likely to occur.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to reliably assemble a separately supplied foldable container with a simple structure. An object of the present invention is to provide a container assembling apparatus for a folding container assembling machine that can be assembled and can be efficiently supplied at regular intervals.

[0011]

[Means for Solving the Problems]

 In order to achieve the above object, the container assembling device in the folding container assembling machine according to the present invention is supplied separately from the folding containers that are stacked in a flat state. In a folding container assembling apparatus for automatically assembling objects into a box, an inner surface of a machine frame of the assembling apparatus is provided with an air cylinder protruding from a base and a pulley suspended above the air cylinder. A pair of elevating devices, which are constructed by connecting an assembly hook lifting plate that holds the upper frame of the separation and supply container to the assembly hook, by chains, are provided facing each other, and at the approximate center of the machine frame. An assembly head, which integrally constitutes a pantograph-shaped press head projecting downward and a spreading head projecting on both sides, is hung on a fishing abutment which is horizontally mounted in the transport direction at the center of the machine frame. Has been installed, By the lifting motion of the lifting device, the assembly hooks rise synchronously while holding the upper frame of the supply container, and at the same time the assembly head also descends and presses and spreads while contacting the front and rear plates of the container. I found out that I could achieve the purpose and completed this device.
