Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for arranging and arranging articles, particularly minute thin articles, on a pallet or jig (hereinafter referred to as a pallet).
The present invention relates to a device for storing, supplying, and positioning pallets so that articles are placed in predetermined positions and postures on the pallets during storage.

Generally, when arranging and storing items on pallets,
You can fix the pallet and use a transfer arm such as a robot that can freely select the transfer position, or you can use a transfer arm that can only move in a fixed, repeated trajectory and move the pallet side in an A method is adopted in which the articles are moved and positioned using a table or the like and then transferred onto a pallet. However, in the former case, since the transfer arm itself positions and postures the article, the arm needs to have a large degree of freedom, and the control becomes complicated. In addition, the latter requires a mechanism for transporting and fixing the pallet from the pallet stock position onto the XY table.

An object of the present invention is to eliminate the above-mentioned drawbacks and provide an article alignment device that does not require a special pallet transfer mechanism when aligning articles using an article transfer arm that performs simple repetition. . The present invention will be explained below based on embodiment figures.

FIGS. 1 and 2 are diagrams showing one embodiment of the present invention. In the figure, a pallet supply table 1 is provided with a large number of circular stepped holes 1a on its circumference. Circular pallets 2a, 2b, 2c, . . . are inserted into the stepped holes 1a and fixed to the table 1. Further, the pallet supply table 1 can be rotated by a constant angle in the direction of arrow B by a rotary indexing device 1b. Reference numeral 3 denotes an article supply device that stores a large number of articles 4, such as a magazine hopper. Between the pallet supply table 1 and the article supply device 3,
A transfer device 5 is installed for supplying articles 4 from the magazine hopper 3 to the pallets 2a, 2b, . . . on the pallet supply table 1. Transfer device 5
In this case, a suction arm 5a for vacuum suctioning the article 4 moves back and forth between the magazine hopper 3 and the article supply position A of the pallet supply table 1.

Below the stepped hole 1a of the pallet supply table 1 at the article supply position A, a pallet positioning table 6 is rotatably provided by a rotating shaft 6a. Reference numeral 7 denotes a drive device for rotating the pallet positioning table 6. Further, the pallet positioning table 6 can be raised and lowered by rotating an elevator shaft 6b by a drive device 7a, and can be moved back and forth and left and right by driving a front-rear shaft 6c and a left-right shaft 6d. Note that the diameter of the pallet positioning table 6 is made smaller than the diameter of the stepped hole 1a.

Next, a method of operating the apparatus of the present invention will be explained. First, the rotary indexing device 1b is driven to rotate the pallet supply table 1 by a certain angle, and the pallet 2a on the pallet supply table 1 is positioned at the article supply position A. Next, the lifting shaft 6b is inserted from below the stepped hole 1a made in the pallet supply table 1.
to move the pallet positioning table 6 to the second position.
As shown in the figure, the pallet 2a is raised to the position 2a', and the pallet 2a is positioned in the height direction. At this time, Fig. 3a and Fig. 3b
As shown in FIG. 2, a gap 2δ is created between the rotary shaft 6a supporting the pallet positioning table 6 and the stepped hole 1a formed in the pallet supply table 1. By moving the front-rear shaft 6c and the left-right shaft 6d through this gap, the pallet 2a can be moved forward, backward, left, and right by δ, respectively. Therefore, as shown in FIG. 4a, after placing the article 4a on the pallet 2a,
By rotating the rotating shaft 6a by α degree as shown in FIG. 4b, and then moving the left and right shaft 6d by x, the article 4
b can be placed in the position shown in Figure 4b. Furthermore, as shown in FIG. 4c, the rotating shaft 6a is
The article 4c can be placed on it by rotating the article 4c by y and moving the front-rear axis 6c by y. After placing the article 4 in a predetermined position on the pallet 2a in a predetermined posture as described above, the rotating shaft 6a, the front-rear shaft 6c, and the left-right shaft 6d are returned to their original positions, and the elevating shaft 6b is lowered. Depending on the situation, the pallet positioning table 6
is lowered, and the pallet 2a on which the workpiece 4 is placed is again installed in the stepped hole 1a on the pallet supply table 1. In this manner, when the workpieces have been aligned on one pallet 2a, the next pallet 2b can be moved to the article supply position A by indexing the pallet supply table 1 by the indexing device 1b.

The pallet 2a on which the articles have been arranged is carried out of the pallet supply table 1 from a pallet take-out position B by a take-out device (not shown). Also, apply adhesive to each pallet in advance,
To prevent workpieces aligned on a pallet from shifting.

The present invention described above has the following effects.

In the present invention, by using a pallet supply table with holes drilled and drilled to match the shape of the pallet, it is sufficient to simply lift the pallet from below, eliminating the need for special pallet transport equipment such as a pallet transfer arm. This makes the device more compact and reduces operating time. In addition, pallets with items arranged and stored can be stored on the pallet supply table simply by lowering them.
The risk of objects shifting on the pallet is also reduced. Furthermore, it becomes possible to arbitrarily arrange the articles on the pallet.

In the above example, the case where articles are arranged and stored on a pallet on a disk has been described.
Even if the shape of the pallet changes, this can be dealt with by changing the shape of the holes and holes in the pallet supply table.
