Description

[Detailed Description of the Invention] This invention relates to an article reversal transfer device.

Generally, in car assembly work, the parts necessary for assembly are first placed on pallets, with large parts placed directly on pallets, and smaller parts placed in containers and placed on pallets before being transported to predetermined locations in the assembly plant. .
This article is then transferred to an article unloading position near the assembler on the assembly line, where it is transferred and
An assembler uses the parts to assemble the parts.

By the way, some of the above-mentioned parts are easily damaged, so they are stored in the above-mentioned container in a lined state and placed on the pallet, so when transferring such parts to the above-mentioned article unloading position, , it is necessary to carefully transfer the parts so as not to damage them, which is very time-consuming.

This idea was devised in view of the above situation, in which containers containing items stored in an array are held between the arms of the transfer mechanism, transferred to the lower part of the receiving plate of the article receiving mechanism, and then transferred to the next place. By inverting the container using a rotary drive means and transferring the article onto the receiving plate, the article is reversely transferred from the loading position to a predetermined article unloading position while maintaining the aligned state of the article. It is an object of the present invention to provide an article reversal transfer device that enables the transfer of articles.

An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 to 4 show an embodiment of the present invention, with Figure 1 being an overall layout thereof, Figure 2 being a front view thereof, and Figure 3 being a sectional view of a container in which articles are housed in an array. , FIG. 4 is a diagram for explaining the operation of this embodiment. In the figure, a pallet 1 is placed at a predetermined placement position 2, and a large number of containers 3 are placed on top of the pallet 1 in a stacked manner. A large number of articles 4 are stored in an array.

Furthermore, the upper surface of the starting end of the belt conveyor 5 for conveying the articles to the side of the assembler (not shown) is
Article unloading position 6 where items are removed from the container 3 and transferred.
An article receiving mechanism 7 is installed to the left of the article unloading position 6, and a robot 8 serving as a transfer mechanism is installed between the article receiving mechanism 7 and the pallet 1.
is installed. Then, the robot 8
is transferred to a location where an article receiving mechanism 7 is located, where the container 3 is reversed and the article 4 is transferred to an article unloading position 6.

A handling part 8a is provided at the tip of the robot 8 so as to be horizontally rotatable.
Arms 9a, 9b are attached at right angles to both ends of the handling portion 8a, and the arms 9a, 9b are attached at right angles to both ends of the handling portion 8a.
b can be moved left and right by the handling section 8a. Clamp heads 10a and 10b are rotatably fitted into the distal ends of the arms 9a and 9b so as to face each other inwardly at right angles.

Also, the left arm 9 of the handling section 8a
A 180° reversal motor 11 is attached to the tip of the clamp head 10a as a rotation drive means for rotating the clamp head 10a.

Further, the left and right legs 12 of the article receiving mechanism 7 are fastened to the floor surface 16 with anchor bolts 12a, and each upper end has a horizontal shaft facing inward at right angles thereto. 13a and 13b are inserted and fixed.

Further, a receiving plate 14 is provided inside the leg 12, the area of the receiving plate 14 is slightly larger than the opening of the container 3, and the receiving plate 14 has side plates 14a and 14b at both ends thereof. , cutouts 14c on both sides of which the arms 9a and 9b can enter,
It has 14d. The receiving plate 14 has the horizontal shafts 13a, 13 on its side plates 14a, 14b.
b is inserted and rotatably supported by the horizontal shafts 13a and 13b.

A spring 15 is fitted in a portion of the horizontal shaft 13b between the side plate 14b and the right leg 12, and the spring 15 is attached to the receiving plate 1.
4 is urged to rotate in the counterclockwise direction as shown in FIG. . Note that 12e is a lower stopper, which is used when the receiving plate 14 is rotated clockwise.
When rotated by 180 degrees, the receiving plate 14 comes into contact with the locking piece 14f to stop the rotation of the receiving plate 14.

Next, the operation will be explained using FIG. 4.

First, the arms 9a and 9b are opened and closed by the handling section 8a of the robot 8, and the clamp heads 10a and 10b at their tips clamp the center of the side surface 3a of the container 3 in which the articles 4 are housed in an aligned state. The container 3 is then transferred to the article receiving mechanism 7 by the robot 8 while keeping its opening surface horizontal. At this time, the receiving plate 14 of the article receiving mechanism 7 is
The spring 15 rotates and urges the locking piece 14f to rotate in the counterclockwise direction in FIG.
It is in contact with d and becomes horizontal. Then, the arms 9a and 9b are moved downward so that the height of the center axes of the clamp heads 10a and 10b match the height of the center axes of the horizontal shafts 13a and 13b of the article receiving mechanism 7, and then the arms 9a and 9b are moved downward. The arms 9a and 9b are moved in the horizontal direction to enter the lower part of the receiving plate 14 of the container 3, and when the two central axes coincide as shown in FIG. 2B, the arms 9a and 9b are stopped.

Next, the clamp head 10a is rotated by the 180° reversing motor 11, and the container 3 is rotated clockwise in the figure (b). As a result, the upper left end of the container 3 comes into contact with the lower surface of the receiving plate 14 and urges the receiving plate 14 to rotate clockwise, and the receiving plate 14 has its locking piece 14f engage with the lower stopper 12e of the leg 12. Until it locks, i.e. rotates 180 DEG and becomes horizontal as shown in FIG.

Next, as shown by the two-dot chain line in FIG. It will be transferred and placed as it is. Then, the container 3 can be further lifted upward, and the empty container 3 can be returned to a predetermined place near the original loading position 2. Also, the articles 4 in other containers 3 can be reversely loaded in the same manner as above. Bye.

According to the article reversal transfer device configured and operated in this manner, the containers 3 in which the articles 4 are stored in an aligned state
are transferred by the robot 8 to below the receiving plate 14 of the article receiving mechanism 7, where the container 3 is reversed 180° by the 180° reversing motor 11, so that the articles 4 can be kept in their aligned state with a simple structure. It is possible to reverse transfer while preserving the .

In the above embodiment, the 180° reversing motor 11 is attached to the arm 9a to rotate the container 3, but this 180° reversing motor 11 is attached to the article receiving mechanism 7 to rotate the receiving plate 14. , The container 3 may be rotated by this, and in this case as well, the same effect as in the above embodiment is produced.

As described above, according to the article reversal transfer device according to the present invention, containers in which articles are stored in an aligned state are held between the arms of the transfer mechanism and transferred to below the receiving plate of the article receiving mechanism, and are driven to rotate. Since the containers are transferred to the unloading position by inverting the container using a means, the simple structure allows the articles to be automatically transferred while maintaining their alignment, reducing man-hours. This has the effect of reducing assembly costs.
