Next, an example of use and operation of the above-described device of the present invention will be described. Here, it is assumed that a container-shaped tofu w, in which a square-shaped tofu is sealed in a resin container, is used as a package and is aligned and housed in a single layer in the upper surface open container T. In a state in which a work start switch of a control panel (not shown) for controlling the whole of the device of the present invention is turned on and not operated, the left and right locking claws 9 and 9 of the container sequential supply unit 1 are the main body frame 6
8A, the empty upper surface open containers T1 and T shown in FIG. 8A are placed on the support member 11 at the initial position p1 shown in FIG. Pile up in a shape.

After that, the work start switch is turned on and operated, and in connection with this, the following processing is automatically carried out. First, the container up-and-down drive unit 8 raises the stacked upper surface-opening containers T1 and T group mounted on the support member 11, and the second uppermost open container T from the bottom causes the locking claw 9 to move. , 9 and the locking claws 9, 9 are displaced toward the center of the width of the main body frame 6 and engaged in the recesses in the left and right side walls of the second upper open container T. To enter. After this engagement is performed, the support member 1
1 is further lowered and displaced so that only the lowest open container T1 is lowered and displaced.

When the lowest open container T1 faces the left and right locking members 19, 19 of the container carrying and supporting mechanism 12, the locking members 19, 19 are located outside the left and right sides of the main body frame 6. The container is displaced from the initial position in the displaced state toward the center of the width of the main body frame 6, and the lowermost upper surface opened container T
The container T1 is inserted into the handle holes h shown in FIG. 8A on the left and right side walls of the container 1 to support the container T1.
It is in a state of being supplied to No. 2. After this, the supporting member 11 further descends and returns to the initial position p1.

Next, the left and right locking members 19, 19 are moved forward together with the sliding members 17, 17, whereby the upper surface open container T1 supported by the left and right locking members 19, 19 is loaded. The aligned storage part 2 is moved to the first load storage position p2 shown in FIGS. 5 and 7 and stopped at the position.

In one of the operations, a large number of cuboid container-shaped tofu w prepared in advance in the vicinity of the transport starting end a1 of the load body arranging mechanism 13 are supplied to the transport starting end a1 one by one, As a result, the tofu w with a container supplied to the transport start end a1 is moved toward the transport end a2 while being supported by the transport surface a.

As shown in FIG. 9, the container-containing tofu w conveyed on the conveying surface a is swung downward around the fulcrum shaft 24 and abuts on the vertically oriented surface portion 25a close to the conveying surface a, and Movement in the transport direction f3 is restricted. Even in this regulated state, the transport surface a continues to be fed and moved, so that the tofu w in each container, which is sequentially transported on the transport surface a, is transported first and locked by the vertical surface portion 25a as shown in FIG. Since the movement of the container-shaped tofu w is impinged against the rear end surface of the container tofu w and the movement of the container-shaped tofu w is regulated in the conveyance direction f3, when the five container-containing tofu w are conveyed on the conveyance surface a in this way, the conveyance direction f3 of the load stopper 222 is determined. The five container-containing tofu w is aligned on the upstream transport surface a in a row in the transport direction f3. At this point, the transport movement of the transport belt 21 is temporarily stopped.

Under the stop, the telescopic cylinder device 27 is shortened, and in conjunction with this, the vertical surface portion 25a is displaced upward, and the tofu w in the container at the frontmost position aligned on the conveying surface a is moved. Then, the pressing member 41 of the load pressing and moving mechanism 15 is displaced downward from the initial position p4 shown in FIG. 5 by the extension operation of the vertically extending telescopic cylinder device 40, and then the telescopic cylinder device 39 is shortened. By the operation, the main body frame 6 is horizontally moved toward the starting end portion 6a side. In the process of this horizontal movement, the load contact portion d of the pressing member 41 abuts the front side surface of the main body frame 6 of the five container-containing tofu w aligned on the transport surface a, and these container-containing tofu w are The tofu row in the container is preliminarily overhanged at the basic height position as shown in FIG. 5, because the tofu row in the container is pushed and moved through the transport surface a and the slide guide surface c without breaking their aligned state. Two support guide plates 32, 32 held by
Is located at the central portion p6 in the front-rear direction of the horizontal upper surface.

Next, the pressing member 41 is a telescopic cylinder device 39.
6 and 7 is returned to the initial position p4 by the operation of the vertical telescopic cylinder device 40, and the vertical surface portion 25a of the load stopper 22 is initialized by the extension operation of the telescopic cylinder device 27 as shown in FIG. Returned to position.

In association with the return of the pressing member 41 and the vertically oriented surface portion 25a, the telescopic cylinder device 35 which has been in the extended state until then is shortened, and the two support guide flat plates 32, 32 are shown in phantom lines in FIG. As shown by b and b, the support guide flat plate 3 has a vertical posture.
The five container-containing tofu w located on the positions 2 and 32 fall due to its own weight. Since the tofu w in the container thus falling is guided to the vicinity of the bottom surface of the upper surface open container T1 by the front and rear support guide flat plates 32, 32 whose front and rear end surfaces are in the vertical orientation, the first row in the upper surface open container T1. Position p
3 will be correctly accommodated in the aligned state.

After this, the left and right bearing members 30, 30 are raised by the contracting operation of the telescopic cylinder devices 29, 29,
The two support guide flat plates 32, 32 are moved to the upper side of the upper surface open container T1 in the vertical posture, and in association with this movement, the telescopic cylinder device 35 of the shaft drive mechanism 33 is shortened to make each rotation. The fulcrum shafts 31 and 31 are rotated in the opposite direction to the front, and the two support guide flat plates 32 and 32 are returned to the extended horizontal posture again. After this return, the telescopic cylinder devices 29, 29 are extended to operate the left and right bearing members 33, 3
0 is lowered, and the two support guide flat plates 32, 32 are returned to the basic height position again.

In one of the operations of the support guide flat plates 32, 32, the transport belt 21 is again fed and moved in association with the return of the pressing member 41 and the vertically oriented surface portion 25a. While on the move, as before,
The tofu w in a container is supplied to the conveyance start end a1 of the load body alignment mechanism 13. As a result, the conveyance direction f3 of the load stopper 22 is
The five container-containing tofu w is aligned on the upstream transport surface a in the transport direction f3 as before.

On the other hand, on the other side of this alignment, the left and right locking members 19, 19 are moved forward by a distance substantially the same as the front-rear length of the tofu w in a container, whereby the left and right locking members 19, 19 are moved. The top open container T1 supported by FIG.
As shown in 0, it is moved to the second loader housing position p7 near the lower part of the loader aligned storage portion and stopped and held.

Next, the pressing member 41 pushes and moves the five container-containing tofu w aligned on the conveying surface a as before, and the horizontal upper surfaces of the two support guide flat plates 32, 32 are moved as shown in FIG. It is located at the central portion p6 in the front-rear direction.

It is precisely positioned at the position p7 of the second row in the open container T1. At this time, when the front side support guide flat plate 32 is rotated around its rotation fulcrum shaft 31 and the position of the first-row container-containing tofu w already stored in the upper surface open container T1 is disturbed, By pressing these container-containing tofu w to the front side, the container-containing tofu w of the second row can be easily accommodated.

After that, the operation of the load body aligning / accommodating mechanism 13 and the operation of the load carrying / supporting mechanism 12 are performed in the same manner as described above, so that the upper surface open container T1 is moved as shown in FIG. Will be moved to the third package housing position p8 near the lower part of the table and stopped and held. Next, the pressing member 41 and the two support guide flat plates 32, 32 operate in the same manner as above, and five new ones are added. The tofu w in the container is maintained in the aligned state and accurately positioned at the position p9 in the third row in the upper surface open container T1 and finally returned to the initial position p4 to prepare for the next operation. As a result, a plurality of container-containing tofu w are densely accommodated in the upper surface open container T1 in an aligned state, and a state in which the upper surface open container T1 can be transported forward by the load carrying and supporting mechanism 12 is possible. Becomes Even when the third-row container-containing tofu w is stored, the front-side support guide flat plate 32 is already stored in the upper surface open container T1 by the rotation around the rotation fulcrum shaft 31. When the positions of the container-containing tofu w in the second row and the second row are disturbed, the container-containing tofu w is pushed to the front side to facilitate the accommodation of the container-containing tofu w in the third row.

After this state, the left and right locking members 19, 19
Are moved further forward together with the left and right sliding members 17, so that the upper surface open container T1 is positioned on the drive roller 43 on the side of the main frame 6 starting end 6a in the roller conveyor section 3, where the main frame 6 Is displaced to the outside on the left and right to release the upper surface open container T1.

The series of operations and processes in the roller conveyor unit 3, the container stacking processing unit 4, and the container stacking unit 5 described above are repeatedly performed thereafter.

In the above embodiment, the rotation fulcrum shafts 31, 3
1 and the support guide flat plates 32, 32 are replaced with a configuration in which they are vertically displaced with respect to the upper surface open container T, instead of the rotation fulcrum shaft 3
1, 31 and the support guide flat plates 32, 32 may not be vertically displaced, and the top open container T1 transported by the container transport support mechanism may be vertically displaced with respect to the support guide flat plates 32, 32. Absent. With this configuration, the structure of the load-carrying and accommodating and accommodating portion 2 is simplified, and the speed of accommodating the load is increased.

Further, the container stacking processing unit 4 and the container loading unit 5
Can be arbitrarily modified, and may be omitted when unnecessary.

Further, the container sequential supply unit 1, the container stacking processing unit 4, and the container stacking unit 5 are omitted, and instead of the container transport support mechanism 12, the upper surface is located at a specific position in the vicinity of the lower part of the packing body alignment and storage mechanism. A container support mechanism 12 that supports the open container T in a stationary state is provided, and the load body alignment accommodating portion 2, the load body alignment mechanism 13, and the load are arranged for the upper surface open container w supported by the container support mechanism 12. The body pressing movement mechanism 15 may be automatically displaced relative to the front-rear direction f1. In this case, it is necessary for an operator to carry in and carry out the upper surface opened container T to and from the container supporting position (position of p2) of the container supporting mechanism 12, or it is necessary for another appropriate mechanism to carry it out. The container-containing tofu w is stored in the open container T in the same manner as described above.

According to the present invention described above, the following effects can be obtained. That is, according to the first aspect of the present invention, by a simple mechanism, a plurality of packages (such as tofu in a container) are not affected even if the shapes of these packages are slightly different. Since it can be surely aligned and tightly housed in the open-top container, and since no suction cup is used for moving the load, it is possible to eliminate accidents such as load drop due to loss of vacuum pressure.

According to the second aspect of the present invention, the empty upper surface open container is mechanically carried in to the package receiving position of the package aligning accommodation part or mechanically discharged from the package aligning accommodation part to another place. As a result, it is possible to reduce the labor of handling the open-top container and store the load with less labor.

According to the third aspect of the present invention, a plurality of loads arranged in a straight line in a single row are not affected by the individual loads even if the shapes of the loads are slightly different. Thus, the open container can be securely aligned and can be tightly accommodated.
