PURPOSE:To solve the shortage of hands and shorten workhours by fixing the required places of both side parts of a conveyor pivotally to a frame, and making the conveyor itself tiltable around the turning fulcrums of the pivotally fixed parts so as to allow containers to be conveyed and reversed. CONSTITUTION:A truck 9 loaded with numerous containers filled with spent hand towels 12 is moved and thrusted onto the fork claw 7 of a belt conveyor 2 in the upright state, and positioned in such a way that the side face of the container 10 is brought into contact with the conveying face 11 of the conveyor 2. With the inclined face formed at the tip of the fork claw 7, the bottom plate of the truck 9 is brought into contact with the upper face of the fork claw 7 by the inclined rotation of the conveyor 2 so as to fix the truck 9. In this state, a hydraulic cylinder 6 is operated to place the conveyor 2 in the horizontal state, and when a belt driving motor is driven, the containers 10 move toward the front end of the conveying face, and the containers fall one by one in the reversed state with the opening part facing downward. A worker recovers the empty containers falling in the turned-over state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container reversing device for conveying and reversing a container by rotating a conveyor itself.

[0002]

2. Description of the Related Art For example, in the wet hand towel industry, used hand towels are conventionally stored in a container and returned. Therefore, as shown in FIG. In this method, the containers are taken out one by one, inverted, placed on a conveyor and moved to the next washing step. Therefore, considerable physical labor was required in this work process.

[0003]

Since a considerable amount of physical labor was required in the above-mentioned conventional process, by developing a device for automatically reversing the container, the labor shortage is solved by improving the work efficiency. It is possible to reduce labor cost, work time, and standardize work processes. The present invention provides a container reversing device that tilts and swivels the conventional conveyor itself so that even if a large number of heavy containers are loaded on a trolley, the containers can be transported and inverted to take out only empty boxes. The purpose is to do.

[0004]

In order to achieve the above object, the apparatus according to the present invention is such that required parts on both sides of the conveyor and a pedestal are pivotally mounted, and the conveyor itself is centered on a pivot fulcrum of this pivotally mounted portion. Is freely tilted, and a carriage receiver is provided on the rear end side of the conveyor.

It is effective to provide an inclination angle on the conveying surface at the front end of the conveyor for the reason described below.

It is also conceivable to dispose a bogie mooring body on the bogie receiving portion, and guide plates may be arranged on both sides of the conveyor conveying surface.

[0007]

In the container reversing device configured as described above, since a large number of containers are in contact with the transport surface of the conveyor together with the carriage, tilting the conveyor causes the container to tilt as it is, The container is conveyed sideways (or diagonally) on the conveyor, the container is inverted at the front end of the conveyor, and the contents are taken out.

The container can be conveniently turned upside down by providing an inclination angle on the conveyor surface at the front end of the conveyor, and if the bogie mooring body is arranged at the bogie receiving part, the bogie will move when the conveyor is inclined. If the guide plates are not separated from the main body and the guide plates are provided on both sides of the conveyor conveying surface, the container conveyance reversal can be more ordered during the tilting operation of the conveyor and the operation of the conveyor.

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that the technical scope of the present invention is not limited to the wording described in the embodiments, drawings, or claims, but extends to the scope equivalent to the claims. FIG. 1 is a perspective view of an embodiment, FIG. 2 is a side view showing an implementation state, and FIG. 3 is an explanatory view of a conventional technique.

As shown in FIG. 1, an inverted T having the same shape on the left and right sides.
A swivel fulcrum 4 is provided on the side surface of the character-shaped mount 1. The pedestal 1 may have any shape. The point is that it can support the main body of the belt conveyor 2 from both sides. The belt conveyer 2 is configured such that the driving surface of the belt is moved by the drive motor 5. Conveyor is container 1
As long as 0 can be conveyed, a belt conveyor or a chain conveyor may be used. Although a drive type conveyor is preferable, driving with a motor is not an essential requirement, and a configuration in which the container on the conveyor is moved manually may be used. Both sides of the belt conveyor 2 are located on both sides of the gantry, and required portions on both sides are pivotally attached by a mandrel, and can be freely rotated vertically or horizontally by a swivel fulcrum 4. . The turning fulcrum 4 is shown near the center of both sides of the belt conveyor 2, and the turning motion is more likely to occur in that direction, but it may be closer to the upper part or the lower part apart from the vicinity of the center. Further, the belt conveyor 2 and the mount 1 are hydraulic cylinders 6
Are connected by. Since the hydraulic cylinder 6 serves as power for turning the belt conveyor 2,
Alternatively, it may be replaced with an air-hydro cylinder or an electric cylinder, or it may be a method of directly driving a swivel axis such as worm & wheel drive, chain drive, rack & pinion drive, or a method in which a chain is hung on a belt conveyor and hoisted by a crane. . The point is that any mechanism can be used as long as it can tilt the belt conveyor about the turning fulcrum.

Next, on the rear end side of the belt conveyor 2, a carriage receiving body made up of a fork melon 7 is provided so as to project at a right angle to the conveying surface 11. The dolly carrier may be in the shape of a melon or a plate, as long as it has a structure for receiving the dolly for carrying containers. In addition, it is preferable to dispose a bogie mooring body such as the magnet 8 in the bogie receiving portion. This is for the purpose of preventing the trolley from tilting forward due to the gap between the trolley and the container when the containers are sequentially sent forward when the belt conveyor 2 is tilted in the horizontal direction. . When the dolly is made of iron or magnetic metal, the dolly mooring body may be a permanent magnet. It is sufficient that the belt conveyor 2 is returned to the vertical state and the casters of the carriage land on it so that it can be naturally separated from the fork melon. Not limited to permanent magnets, means such as hooking a dolly or caster to a dolly receiving part such as a fork gourd can be considered.

The carrying surface of the belt conveyor 2 may be parallel to the top and bottom, but an idle roller 12, etc., which can be adjusted back and forth as shown in FIG. 2, is interposed on the front end side thereof so that the carrying surface has an appropriate inclination angle. For example, the container can be successfully turned over and dropped on the next process surface. The guide plates 3 may be arranged on both sides of the conveyor surface of the belt conveyor. This guide plate prevents the container itself and its contents from falling off the conveyor.

Now, the trolley 9 on which a large number of containers filled with the used hand towels 12 are loaded is moved, and the trolley 9 is placed on the fork melon 8 of the belt conveyor 2 in the upright state.
Is pushed in, and the side surface of the container 10 is positioned so as to abut the conveying surface 11 of the conveyor 2. Fork melon 7
If the tip of the fork melon 7 is slightly lower than the position of the bottom plate of the dolly 9, the tilting of the conveyor-2 causes the bottom plate of the dolly to come into contact with the top face of the fork melon 7 and the magnet 8 The dolly is fixed. In this state, the hydraulic cylinder 6 is operated as shown in FIG. 2 to make the conveyor 2 horizontal. Then, when the belt drive motor is driven, the container moves toward the front end of the transport surface, and the container 10
Are dropped one by one with their openings facing down. In the next step, a separate sorting conveyor is usually installed, so the worker collects the empty containers that have fallen face down.
When all the containers on the belt conveyor are exhausted, the belt conveyor 2 may be returned to its original state. The above description has been given by taking the hand towel collection work as an example, but for example, in the work of collecting agricultural products, tomatoes, onions, carrots, etc. are carried on a pallet, and heavy boxes are manually turned over to perform sorting work. It is also possible to use this reversing device.

[0014]

Since the present invention is constructed as described above, it has the practical effects as described below.

Since the carriage is provided on the belt conveyor and the belt conveyor itself is tilted, it is possible to invert the containers as they are without having to take out a large number of heavy containers loaded on the carriage one by one. Can be realized, labor costs can be reduced, work time can be shortened, and work processes can be standardized.

By providing an inclination angle on the front end conveying surface of the conveyor, the container can be accurately inverted.

By attaching the bogie mooring body to the bogie receiving body, it is possible to prevent the bogie from falling on the belt conveyor in a horizontal state.

By disposing the guide plates on both sides of the conveyor conveying surface, it is possible to prevent the container itself and its contents from dropping off from the conveyor.
