Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a container separation device for separating a plurality of folding containers, which are stacked and supplied in a flatly folded state, and supplied to an assembling device.

[0002]

[Prior art]

 Foldable containers are well known, and they are used in large numbers because they can be stacked in a flat plate shape for easy storage or transportation, and this folding container is used as a box. At that time, it was used by assembling them after manually picking them up one by one from the stacked ones, but recently, a device was developed that automatically separates and supplies the folding containers in a stacked state. The ones described in Japanese Patent Application Laid-Open No. 55-111324 and Japanese Utility Model Laid-Open No. 2-97324 are known.

[0003] Among the above-mentioned ones, in Japanese Patent Laid-Open No. 55-111324, the lowermost container upper frame of stacked folding containers is held by an impeller arranged opposite to each other. It is described that the containers are separated one by one by releasing the holding of the container upper frame by rotating.

In Japanese Utility Model Laid-Open No. 2-97324, the lowermost upper frame of the stacked foldable containers is hooked, and the bottom plate is also pinched by the holding part, and the bottom plate is hooked from below. It is described that the container is separated by holding by hooking with and the container is separated by releasing the holding of the container by these hooks and the holding part.

[0005]

[Problems to be solved by the invention]

 However, the foldable containers are folded and stacked in a flat plate shape during storage or transportation, but when they are used as boxes, they are manually taken out from the stacked ones and assembled. Supply was irregular and the work efficiency was poor.

Therefore, a device for separating and supplying the foldable containers in the stacked state described above in the related art has been devised, but in JP-A-55-111324, the foldable container in the stacked state is proposed. Although it is possible to separately supply containers one by one, the bottom plate is not held because the bottom frame of the container is held only by the engagement of both impellers, so the bottom plate falls due to its own weight. If the bottom plate falls, it will contact the upper frame of the collapsible container that has been separated downward, and the container transportation position will change, which will hinder the transportation to the assembly equipment and will ensure proper supply. There was a problem that it was often impossible to do.

According to Japanese Utility Model Laid-Open No. 2-97324, although the stackable collapsible containers can be separately supplied one by one, a failure occurs because each mechanism constituting the device is minute and complicated. The bottom plate is not securely clamped due to a decrease in the clamping force of the clamping part, so the bottom plate opens by its own weight, and since this bottom plate opens, it is no longer possible to hook the bottom part of the bottom plate with the hook. It will fall due to its own weight and it will not be possible to reliably separate it, and the dropped bottom plate will contact the upper frame of the foldable container that has separated downwards and the transfer position of the container will change, obstructing the transfer to the assembly equipment. However, there was a problem in that it often happened that appropriate supply could not be achieved.

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 provide a stackable collapsible container with a simple structure having a small installation area. Further, the present invention intends to provide a container separating device in a folding container assembling machine which can surely achieve separation and can efficiently supply at a constant interval.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the container separating device in the folding container assembling machine according to the present invention separates one by one from the folding containers which are stacked in a flat and plate-like folded state, and is sequentially assembled into assembling devices. In the separation device of the folding container to be supplied, the upper frame of the lowermost container is attached and detached via the pulley on which the air cylinder protruding from the base is suspended inside the machine frame of the separation device. The upper frame holding part that holds the bottom plate of the bottom container and the bottom plate holding part that holds the bottom plate of the lowermost container in a detachable manner are chained together. A pair of vertically connected lifting devices are provided so as to face each other, and the lowering motion of the lifting devices causes the holder to move synchronously while holding the upper frame and bottom plate of the lowermost container and transport the stacked containers. At the same time, the tension springs that connect the upper edges of the holding body lifting plate and the protrusions on both ends of the fixed shaft that traverses approximately the front end of the upper frame holding section are retracted and the holding body is out of synchronization. The lowermost container is released from the holding by tilting inward, and immediately after that, the holding body is guided by the guide plate mounted on the support of the machine frame by the ascending motion of the ascending / descending device, and the second inward is tilted in synchronization. It was found that the purpose can be achieved by holding the upper frame and the bottom plate of the container at the same time, and further raising the containers synchronously while holding the stacking container to separate the lowermost container. I arrived.

A rectangular rectangular holding body lifting plate (16) to which the above holding body (15) is fixed, is attached to the inward rising surface of the groove formed in a substantially U-shape that continuously extends. A slide rail (17) that is attached to a plate (18), and a sliding body (19) provided on the back surface of the slide plate (18) is slidably engaged. Is vertically installed from the bottom edge of the machine casing (1), and is closely attached to the inner surface of the machine casing (1) so that the inward facing back plate (36) and door plate (37) face each other. On the ceiling plate (4) of the base (2), the tip of the cylinder rod of the air cylinder (22) for raising and lowering the holder and the holder raising / lowering plate (16) projecting with the cylinder rod facing upward, the slide rail (17). ) Is connected by a chain (21 1,2) via a pulley (20 1,2) suspended in the center of the bottom edge of the beam (11) above the installation location of ) Foldable containers (9 1,2, ... n) that are piled up and sent in the inside of), project the tip of the cylinder rod onto the transport surface on the center line of the accumulator roller conveyor (10). A stopper cylinder (23) is provided so as to abut and stop at a position where the holding body (15) can be securely held.

As shown in FIGS. 4 and 5, the holding body (15) is a flat plate shape in which both ends in the longitudinal direction are cut in a wedge shape inclining from the upper surface to the bottom surface, and the planar central portion of the rectangular parallelepiped is formed into a rectangular shape. An upper frame holding part (24) formed by opening and a flat plate shape with a tip cut off from the bottom surface to the top surface in a wedge shape, and a rear end of a substantially rectangular parallelepiped tilted downward from the substantially central portion of the bottom surface. The bottom plate holding part (25) is formed by projecting to the bottom, and the tip of the wedge part projecting downward at the rear end of the bottom plate holding part (25) projects from the bottom surface of the upper frame holding part (24). A shaft that is fitted into the opening and is rotatably provided on the side surface of the upper frame holding portion (24) in the longitudinal direction and the side surface of the wedge portion that is fitted into the opening. The fixed shaft (26) is transversely extended in parallel with the both ends protruding to the approximate center through the hole. A compression spring (27) is attached to one side surface of the rear wedge portion of the holding portion (25), and the outside of both protruding ends is locked to the widened surface of the front wedge portion. It is fixed and wound. Further, the protrusions at both ends of the fixed shaft (26) that crosses the substantially central portion of the upper frame holding portion (24) of the holding body (15) face the lower side edge of the front surface of the holding body elevating plate (16). Are supported by a pair of fixed bearing bases (28) and extend through the projections at both ends of the fixed shaft (26) that crosses approximately the tip of the upper frame holding part (24) and the tension springs (29). The holding body elevating plate (16) is fixed to the holding body elevating plate (16) by connecting the upper edge of the front surface of the holding body elevating plate (16). Holds a substantially prismatic tilting body (31) with a cam follower (30) protruding from the lower end of the outer side that is attached to one end of the protrusions on both ends of the fixed shaft (26) that traverses each side surface On the other hand, the inboard back plate (36) of the machine frame (1) and the pillars (12 1,4) of the door plate (37) that face each other are attached to the body (15) and follow the shape of the back surface Roll over In particular, a guide in the shape of a prism in which the upper and lower ends are tilted from the front to the back at a position where the holder (15) can be tilted in conjunction with the tilting body (31) that tilts in response to this. The plate (32) is installed vertically with the sides fixed.

The foldable containers (9 1, 2, ... N) that are configured as described above and are stacked on the accumulation roller conveyor (10) in a folded state are When it is fed onto the accumulator / roller conveyor (10) in (1), it is brought into contact with the extended cylinder rod of the stopper cylinder (23) projecting from the base (2), and onto the conveyor (10). The holding body (15) at this point is fixed to the holding body lifting plate (16) and tilted outward by the contraction of the tension spring (29) and folded upright. At the lowest point on the slide rail, the air cylinder (22) for raising and lowering the holder operates in conjunction with the suspension of feeding of the foldable container (9) to retract the cylinder rod, and Accordingly, the holding body (15) also rises from the lowest point on the slide rail (17) and further rises. And the cam follower (30) protruding outward from the side surface of the tilting body (31) comes into contact with the guide plate (32) provided on the support columns (12 1, 4), and the cam is lifted when passing through the guide plate (32). The holding body (15) gradually tilts inward as the follower (30) follows the undulating surface of the guide plate (32), but this holding body (15) tilts inward while rising. The upper frame (13) and the bottom plate (14) of the second-stage container (92) of the foldable containers (91,2, ... n) that are stacked by this are gradually and simultaneously held from below. The holding body (15) that has passed through the guide plate (32) holds the second-stage container (92), and therefore is prevented from tilting outward. Further, the holding body (15) holds the second-stage container (92) and continues to move up the slide rail (17), then stops at the highest point, and this rise causes the second-stage container (92) and the lowest stage. The container (91) is separated, the stopper cylinder (23) is activated at the same time when the rising is stopped, the cylinder rod is retracted, the stopper is released, and the container is separated and placed on the accumulation roller conveyor (10). The placed lowermost container (9 1) is supplied to the assembling apparatus. Immediately after the lowermost container (91) is supplied to the assembling device, the holding body (15) descends from the uppermost point while holding the second-stage container (92) and moves up on the accumulation roller conveyor (10). Then, the holding body (15) further descends to release the holding of the container (92), and the tension spring (29) retracts to tilt outward and fold upright. It becomes a state and stops at the lowest point. By repeating the above-mentioned operation, the foldable containers (9 1,2, ... n) that are stacked and conveyed in the folded state are separated one by one and sequentially supplied to the assembling device.
