Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a reversing device for containers used when discharging processed materials from processing containers in a metal removal line.

(Prior Art) A conventional container inverting device that inverts the containers and discharges the product inside the containers in order to send the products placed in the containers to the next process is to transfer the containers sent by a conveyor to an elevator. Usually, the container is placed on a holder that moves up and down and lifted upwards, and when the holder reaches the top of the elevator, the holder is automatically rotated to invert the container (for example, Utility Model Publication No. 52-25781 (Publication) (Problems to be Solved by the Invention) However, in all of the conventional container reversing devices as described above, the reversing position of the containers is high, so when incorporated into a series of processing lines, it is difficult to connect to other processes. In addition, there are other problems such as the overall height of the device becomes high, and the structure becomes complicated, large-sized, and expensive.

(Means for Solving the Problems) The present invention has been completed for the purpose of a reversing device for containers that solves the above-mentioned problems. A rotating body is provided in parallel with the direction, and a rearward-facing guide rail is integrally attached to both upper rails.A rotating body is engaged and supported by a wheel provided on the outer surface of its center, and the guide rail is attached to the rear of the rotating body. Each support member has a receiving frame body in which the front end of the support member is pivotally attached to both front sides of a rectangular frame member that has a front wheel that is always engaged with the rail and a rear wheel that is freely engageable and detachable from the guide rail at the upper end. A guide wheel provided at the rear end is engaged with and supported by the lower rail, and a drive device for moving the receiving frame forward and backward is connected to the receiving frame, and a drive device is connected to the front part of each guide rail of the rotating body. The present invention is characterized in that a stopper is provided, which is brought into contact with a front wheel when the receiving frame moves forward, and causes the rotating body to rotate together with the guide rail and the receiving frame supported thereon.

(Function) This kind of container reversing device uses a drive to pull the receiving frame with the container placed on the receiving frame, and engages the rear wheels with the guide rail, which the front wheels are always engaged with. At the same time, the receiving frame body that engages the guide ring at the rear end of the support member with the lower rail is advanced. When the front wheel continues to pull the support frame even after reaching the stopper, the rotating body is pushed by the support frame and starts rotating, so the guide rail that is integrated with the rotating body also rotates, and this guide rail The receiving frame, which is supported by engaging the front and rear wheels, also rotates, and the containers placed on the receiving frame are turned over as the receiving frame rotates, and the stored articles are discharged at the front end position. After being ejected, the drive device is reversely driven to return to the old position in the completely reverse procedure to the above, and this operation is repeated thereafter.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. 1, 1 and 2, 2 are stretched in parallel in the lateral direction from the container loading location to the container reversing location. An upper rail and a lower rail made of groove-shaped steel, and the upper rails 1, 1 are equipped with rotating bodies 3, 3.
are supported by engaging wheels 10, 10 provided on the outer surface of the center thereof, and a guide rail 4 made of groove-shaped steel is integrally attached to the inner surface of each rotating body 3 facing backward. Reference numeral 5 denotes a receiving frame body on which a container is placed and reversed, and the receiving frame body 5 has front wheels 6, 6 that are always engaged with the guide rails 4, 4, and wheels that are always located behind the guide rails 4, 4. A frame member 5a is provided with rear wheels 6', 6' that can be freely engaged and detached from the guide rails 4, 4, and the front end is pivotally connected to the shafts of the front wheels 6, 6 on both front sides of the frame member 5a. The guide wheels 8, 8 provided at the ends are connected to the lower rail 2,
2 and supporting members 7, 7 engaged with each other. 9 connects each rotating body 3 with a tube 9' to hold the opposing rotating bodies 3, 3 in the same relative position.
This connecting member 9 also serves to prevent the tube member 9' from falling off when the container is turned over. Further, in this embodiment, there are provided two parts on the outer circumferential surface of the rotating body 3 so that the rotating body 3 is rotated when pushed by the receiving frame body 5.
A chain of books is wound, and one chain 11 is connected to a rotating body 3 from a fastener 12 attached to a lower rail 2.
The end of the chain 11 is fixed to a stopper 13 provided on the rotating body 3, and
The other chain 11' is wound clockwise around the rotating body 3 from a fastener 12', and the end of the chain 11' is fixed to a stop 13' provided on the rotating body 3. 14
is a holding piece fixed to the receiving frame 5 by coming into contact with the supporting member 7 so that the receiving frame 5 is positioned horizontally at the container mounting location, and a wheel 6' is pivotally supported at the rear end of the receiving frame 5. has been done. Reference numeral 16 denotes a drive device for moving the receiving frame body 5 forward and backward. The connecting tool 19 attached to is connected to the supporting member 7 of the receiving frame body 5 via a connecting rod 20. Further, the guide rail 4 of the rotating body 3
When the receiving frame body 5 moves forward along the guide rail 4, the front wheel 6 comes into contact with the front part of the receiving frame body 5, and the rotary body 3 is moved between the guide rail 4 and the receiving frame body 5 supported by the guide rail 4.
A stopper 21 is provided for rotation together.
Note that 22 is a stopper that prevents the rotating body 3 from rotating counterclockwise, and 23 is a conveyor that transports the product in the inverted container I to the next process.

With this structure, for example, at the Metsuki factory, a product that has been subjected to centrifugal dehydration after chromate treatment is placed in a container A, and the container A is placed on the horizontal receiving frame 5 at the container loading location. , the motor 17 of the drive device 16 is activated, and the support member 7, which is connected to the chain 18 through the connector 19, moves along with the receiving frame 5 through the guide wheel 8 toward the container reversal point on the motor 17 side. do. In this case, the front wheel 6, which is always engaged with the end of each guide rail 4, moves forward toward the center of the stationary rotating body 3, and the rear wheel 6, which is normally detached from the guide rail 4, moves forward toward the center of the stationary rotating body 3. The wheels 6' are also engaged with the guide rail 4 and move forward along it, so that the front wheels 6'
When the support frame 5 moves forward until it comes into contact with the stopper 21 of the guide rail 4, the movement of the receiving frame 5 with respect to the guide rail 4 is stopped, but the chain 18 continues to move forward together with the support member 7, so that the chains 11' and 11' The wound rotating body 3 is unwound from the other chain 1 at the same time as one chain 11 is unwound from the circumferential surface of the rotating body 3.
1' is wound around the circumferential surface of the rotating body 3, and the rotating body 3 rotates clockwise through the wheels 10 while moving the upper rail 1.
The support member 7 also moves in the same direction via the guide ring 8 along the direction of the container inversion point. As the rotating body 3 moves forward while rotating clockwise in this way, the guide rail 4 also rotates in the same direction.
The receiving frame 5 is moved from a horizontal state to an inclined state as shown in FIG. 4, and then as the chain 18 continues to move forward, the receiving frame 5 is sequentially moved from the inclined state to an inverted state due to the rotation and movement of the rotating body 3. The frame body 5a
The upper container A is turned over 180 degrees as shown in the figure, but at this time, a limit switch (not shown) stops the rotation of the motor 17, and the container I, which is in the inverted state, stops moving, and therefore everything inside the container The products will be discharged to the conveyor 23 and carried out to the next process, and when the container A is turned over, the pipe material 9' of the connecting member 9 will be located directly below the opening of the container A, preventing the container A from falling off. Prevented. In addition, since the container A to be inverted is inverted while moving at a position away from its center plane, when moving from the tilted state to the inverted state, the lower end of the opening of the container A is displaced in height and in the front-back direction. Since the product in the container A is small in number, the product in the container A can be concentrated and transferred onto the conveyor 23, etc., without being scattered over a wide area when being discharged. Note that after the container 1 is reversed, if the drive device 16 is operated in reverse to move the receiving frame 5 in the opposite direction, the rotation of the receiving frame 5 is stopped by a limit switch (not shown), and the frame of the receiving frame 5 is in a horizontal state. The material 5a can be replaced with the next container A containing the product, and thereafter the same action as described above is repeated, and the container A is turned over and the product inside is continuously discharged. Although the rotating body 3 in this embodiment has two chains 11 and 11' wound around its outer circumferential surface, the rotating body 3 may be a gear and a rack may be provided to mesh with the gear. .

(Effects of the Invention) As is clear from the explanation of the above embodiments, the present invention allows the container to be inverted at a low location, so it can be incorporated into a part of the line and removed from the container at the same height as other processes. It has various advantages, such as being able to discharge water, reducing the overall height of the device, making the entire device more compact, and having a simple structure with fewer failures. It has an extremely large impact on the industry as it solves the problems of the industry.
