Abstract

PURPOSE:To make a table device, which is to put small and thin articles in alignment to load on a jig, in a small size by furnishing a rotary table on its circumference with a numver of stepped holes for fitting of pallets, and by installing a pallet lifting device and a fore-and-aft, right-and-left moving device in the position of feeding. CONSTITUTION:A pallet feed table 1 is revolved for a certain angle by an indexing device 1b, and a pallet 2a is located in the article feed position A. A pallet locating table 6 is lifted from under a stepped hole 1a by an elevating shaft 6b so as to make vertical location of the pallet 2a. The pallet 2a is moved fore and aft and to the right and left by a fore-and-aft shaft 6c and a left-and-right shaft 6d for an amount corresponding to the dimensional difference between the stepped hole 1a and shaft 6a, to place the article in the specified position on the pallet 2a. Then the pallet 2a is fitted back into the stepped hole 1a, and the table 1 is turned for a specified angle. Repetition of this procedure will transfer the pallet to the takeout position. Thus the device is made in small size and can work with a shortened operating time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for placing articles at predetermined positions on the pallet in a predetermined posture when arranging and storing articles, particularly minute thin articles, on a pallet or jig (hereinafter referred to as a pallet). This relates to a device for stocking, supplying, posture and positioning of pallets.

Generally, when arranging and storing items on pallets, the pallets are fixed and the transfer arm of a robot is used to freely select the transfer position, or the pallets are simply moved in a fixed trajectory repeatedly. A method is adopted in which a transfer arm that cannot be moved is used, the pallet side is moved and positioned using a table, etc., and then the articles are transferred onto the pallet. However, in the former case, since the transfer arm itself positions the article and adjusts its posture, the arm needs to have a large degree of freedom and the control becomes complicated.

In addition, in the latter case, 9α from the stock position of the pallet
A mechanism was required to transport and secure the pallet onto the table.

An object of the present invention is to eliminate the above-mentioned drawbacks, and to provide the following advantages when aligning articles by means of an article transfer arm that performs simple repetition.
To provide an article alignment device that does not require a special pallet transfer mechanism. 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 charged 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 60, articles 4 are transferred from the magazine hopper 3 to the pallet 2 of the pallet supply table 1.
A marking device 5 is installed for supplying data to a, 2b, . In the # loading device 5, a suction arm 5a for vacuum suctioning the article 4 is configured to reciprocate between the magazine hopper 3 and the article supply position of the pallet supply table 1.

Stepped hole 1a of pallet supply table 1 at article supply position A
Below the pallet positioning table 6 is a rotating shaft 6a.
It is rotatably provided. 7 is a drive device that rotates the pallet positioning table 6. In addition, the pallet positioning table 6 moves the lifting shaft 6b to a drive device 7a.
It can be raised and lowered by rotating it, and can be moved back and forth and left and right by driving the front and rear shafts 6c and the left and right shafts 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. Next, the lifting shaft 6b is operated from below the stepped hole 1a made in the pallet supply table 1, and the pallet positioning table 6
As shown in Figure 2, raise the pants) 2a to 2a'
The pallet 2a is then lifted up to the position , and the pallet 2a is positioned in the height direction. At this time, as shown in FIG. 6(a) and the third enclosure, the rotating shaft 6 supporting the pallet positioning table 6
5 gaps 2c are formed between a and the stepped hole 1a formed in the pallet supply table 1. By moving the front-rear axis 6C and the left-right axis 6d through this gap, the pants 2a can be moved forward, backward, left, and right by 6, respectively. Therefore, as shown in FIG. 4(a), first, after placing the article 4a on the panties 2a, rotate the α ipsilateral axis 6a as shown in FIG. Article 4 by moving only
b can be placed in the position shown in FIG. 4(b). Furthermore, as shown in FIG. 4(C), the rotating shaft 6a is rotated by β ipsilaterally, and the front-rear shaft 6C is moved by y, thereby making the article 4C.
You can put . After placing the article 4 at a predetermined position on the pants 2a in a predetermined posture as described above, the rotating shaft 6a and the front-rear shaft 6c are moved.

By returning the left and right shafts 6d to their original positions and lowering the lifting shaft 6b, the pallet positioning table 6 is lowered.
The panties 2a on which the work 4 is placed are again fitted into the stepped holes 1aK on the pallet supply table 1.

In this manner, when the workpieces have been arranged on one pallet 2a, the first pallet 2b can be moved to the article supply position A by indexing the pallet supply table 1 using the opening device 1b.

Note that the panties 21 in which the articles have been arranged are carried out of the pallet supply table 1 from the pallet take-down position B by a take-out device (not shown). Furthermore, adhesive is applied to each pallet in advance to prevent the workpieces aligned on the 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 only necessary to lift the pallet from below, and a special pallet transporting device such as a pallet transfer arm is not required. 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 postures of the articles on the pallet.

In this embodiment, we have described the case where articles are arranged and stored on a pallet on a disk, but even if the shape of the pallet changes, this can be handled by changing the shape of the holes and holes in the pallet supply table. can.
