BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for continuously expanding and folding a folding container.

[0002]

2. Description of the Related Art There are folding containers that are reduced in height and folded flat. This folding container is supplied with the contents in a three-dimensional state and makes the transportation of the contents rational, while it is folded after the contents are taken out and the volume is significantly reduced. It is reduced to make it more reasonable to move and store yourself.

When a large number of such folded containers are used, a great deal of time and labor is required for the process of unfolding the three-dimensional container in a folded state. 2. Description of the Related Art A folding container continuous unfolding three-dimensional apparatus for continuously unfolding three-dimensionally has appeared.

The above-described apparatus for continuously expanding and folding a folding container tends to be larger than the size of the folding container, and moreover, there is much useless movement accompanying the processing for expanding and folding the folding container. In addition to a relatively long developing three-dimensional processing time, the driving mechanism tends to be complicated and expensive. An object of the present invention is to provide a folding container continuous deployment three-dimensional apparatus which can solve such a problem.

[0005]

In order to achieve the above object, according to the present invention, there is provided a transport unit for transporting a folding container in a specific lateral direction,

And a side part standing displacement applying part for pushing outwardly in a specific direction to stand up.

According to this, the folding container transported to the specific position by the transport unit is provided with only the displacement necessary for the unfolding and three-dimensional processing from each unit while the bottom is fixed by the bottom position holding unit. As a result, the three-dimensional state can be relatively quickly expanded from the folded state. Further, the bottom position holding section, the upper rising displacement applying section, and the side section standing displacement applying section operate properly in a state where they are vertically arranged.

The above invention may be embodied as follows. That is, as described in claim 2, the bottom position holding portion, the upper rising displacement applying portion, and the side portion standing displacement applying portion are connected by the link mechanism, and a driving force is applied to a specific portion of the link mechanism. And According to this, each part is operated by a single driving means such as a motor, and the driving mechanism is simplified.

According to a third aspect of the present invention, the lowermost one of the plurality of folded containers stopped at a specific position on the trajectory of the transporting surface of the transporting unit on the trajectory upstream of the bottom position holding unit in the transporting direction. After lifting the upper one including the second one from above, and transporting the lowermost foldable container to the specific position of the bottom position holding part under the lifting state, the second one is included. The upper container is lowered to be supported by the conveying surface of the conveying section, and the upper container including the second container from the bottom of the folding containers thus supported is again lifted. Provide a container lifting part.

According to this, the folding container group placed on the transport surface of the transport section transfers each of the folding containers to the bottom position holding section accurately with a relatively small vertical displacement of the folding container. Will be supplied.

Next, an example of use and operation of the above-described device of the present invention will be described. A group of folded containers w obtained by stacking a large number of folded containers w in a stacked state is positioned inside the container guide frame 8c of the loading unit 3 by using a forklift or the like, and guided by the guide frame 8c. While being placed on the transport surface g1. At this time, the container guide frame 8c acts to maintain the verticality of the group of folded containers w stacked high, and prevents the folded containers w from falling down.

The group of folded containers w placed in this way is conveyed inward into the relatively low vertical frame 2 at an appropriate timing by the rotation of the drive roller 6 forming the conveying surface g1. After the conveyed folding container w group is appropriately conveyed forward from the mounting position, the next group of the folding container w group is again containerized by using a forklift or the like as necessary. It is placed inside the guide frame 8c.

The folding containers w placed one after another in the carry-in section 3 are sequentially conveyed to the conveyance start end of the conveyance surface g2 of the center section 4 by the rotation of the drive roller 6, where the conveyance of the center section 4 is performed. The transfer surface g2 in the vertically-oriented frame 2 is transferred to the pair of right and left transfer belts 7 forming a surface g2, and thereafter, the belt 7 is rotated around.
It is conveyed toward the upper specific position h0. When the group of folding containers w reaches the specific position h0, this is detected by a sensor (not shown) of the loading unit 3 and the group of folding containers w on the transport surfaces g1 and g2 of the loading unit 3 and the central unit 4 performs transportation. Stopped.

At this time, the left and right frontward and rearward plates 49 of the container lifting portion E are both at the standby position where the height is slightly larger than the height of the folded container w in the folded state from the transport surface g2. Are also displaced outward in the left-right direction, so that the pressing members 50 of the front-rearward plates 49 do not contact the side portions a1, b1 of the folding container w.

Next, the output shafts 48a of the left and right pneumatic cylinder devices 48 of the container lifting portion E are simultaneously displaced downward, and in conjunction with this, the left and right frontward facing plates 49 are displaced inward in the left and right direction. Due to the displacement, the pressing member 50 of the left and right frontward facing plate 49 is moved to a specific position h on the transport surface g2.
Since the right and left sides a1, b1 of the plurality of folding containers w, including the second one from the bottom of the stack of folding containers w supported at 0, are almost simultaneously pressed. With this, the container lifting unit E is in a state where the plurality of folding containers w are sandwiched from left and right.

Thereafter, the second drive motor 51 rotates to rotate the intermediate shaft 52 and the arm member 55 through the arm member 52, the link member 54, and the arm member 53 by a fixed angle, and further through the link member 57. Third slide body 47

Thereafter, the first drive motor 37 rotates to rotate the intermediate shaft 38 by a fixed angle via the arm member 40, the link member 41, and the arm member 39, and further, the arm members 42, 42 and the link member 43, The first slide bodies 16, 16 are raised to the height of the upper part b of the folded container w in the unfolded three-dimensional state via 43, whereby the upper part b is placed under the state in which the bottom part a is supported by the transfer surface g2. And the left and right side plates c, c attached thereto are developed in a flat state from the folded state. At this time, the front and rear side plates d, d tend to slightly swing around the left-right axis e due to their own weight.

On the one hand, the rotation of the intermediate shaft 38 is carried out via the arm member 44 and the link member 45.
Is lowered toward the position of the imaginary line i, whereby the circular members 34 of the front and rear lateral coupling members 32a and 32b approaching each other as shown by solid lines in FIGS. As a result, the side plates d, d before and after the upper portion b being raised at the specific position h1 are pressed from above, and further swung around the horizontal axis e.

When the second slide body 27 is lowered or after the second slide body 27 is lowered to the position indicated by the imaginary line i, the output shaft 30a of the pneumatic cylinder device 30 is displaced downward, and the front and rear arm members 31a and 31b are linked. The front and rear circular members 34 are opened to the front and rear as indicated by phantom lines via the 36 and 36, whereby the arm members 31a and 31b
Together with the front and rear side plates d, d, which had been pushed only downward until now, are pushed outwardly in the front-rear direction f1 to stand upright.

As described above, the folding container w at the specific position h1 is completely unfolded and formed into a three-dimensional state. After that, the first drive motor 37 rotates in the reverse direction to return each part to the original position.

One of the operations of the bottom position holding section B, the upper rising displacement applying section C, and the side section standing displacement applying section D, the second drive motor 51 rotates in the reverse direction to lower the third slide body 47. The foldable container w including the second one, which is sandwiched, including the second one, is supported by the transport surface g2 at the specific position h0. Next, the output shafts 48a of the left and right pneumatic cylinder devices 48 are displaced upward to displace the left and right frontward facing plates 49 outward in the left and right direction, thereby releasing the folding containers w including the second one and above. Thereafter, the second drive motor 51 rotates to position the left and right front-facing plates 49 at the standby position. Under this state, the left and right pneumatic cylinder devices 48 operate as before, and Left and right side portions a1, a plurality of folding containers w above this, including the second one from the bottom,
b1 presses the left and right pressing members 50, and the second drive motor 51 is further rotated to lift up the folding containers w above this, including the second surface again, and bring these containers into contact with the transport surface g2 at the lowermost stage. Is separated from the folding container w.

In this state, the transport belts 7, 7 in the central portion 4 are operated to send out the processed folding container w onto the transport surface g3 of the unloading section 5, and to move the folded container w into the relatively low vertical frame 2. Is conveyed toward the specific position h1 in the relatively high vertical frame 1 at the specific position h0. On the other hand, the processed folding container w that has reached the unloading section 5 is further unloaded backward by the unloading section 5.

After that, the folded container w which has reached the specific position h1 is expanded and three-dimensionalized in the same manner as described above, and then conveyed to the unloading section 5, and in connection with this conveyance, the container is in contact with the conveying surface g2 at the specific position h0. The process in which the lower folding container w is transported toward the specific position h1 as before is repeated. After the processing of the group of tiered folding containers w is completed, the next group of tiered folding containers w is automatically conveyed to the specific position h0 in the same manner as described above. Will be done.
