Reference numeral 13 denotes an engaging projection protruding from one side of the support portion 10.

As shown in FIG. 3, 14 is a roller supported at both ends of both the front and rear connecting shafts 8 on the outside of the support plate 6.7, and is installed so as to extend in the front and back direction on the outside of both the support plates 6.7. It is supported so as to be movable in the front and rear directions on a pair of left and right rails 15. Reference numeral 16 denotes an engaging piece whose base end is supported by the free end of a leaf spring 17 fixed to the inner edge of both the front and rear sides of the running groove 2, and has slanted portions 168 on both upper and lower surfaces. 16b.

As shown in FIG. 2, 1B is an anti-slip band as an anti-slip member attached to the transfer surface 1a of the transfer table 1 along the transfer direction on both left and right sides of the running groove, and in this embodiment, the transfer surface is Item W1 for 1a. Tray 1 containing W2
Artificial turf with a friction coefficient greater than 9 (with flexible protrusions made of synthetic resin planted on the surface)
is cut into strips and molded, and the top surface of the product W is cut into strips.
1. The tray 19 containing W2 runs.

Reference numeral 20 denotes a guide rod rotatably attached to support members 21 fixed to both left and right sides of the front portion of the transfer table 1, the tip of which passes over the transfer surface 1a and connects to the penetration groove 3 on the rear side.
It extends to the vicinity and prevents the tray 19 from shifting in the left and right direction during travel.

Reference numeral 22 denotes a fixing member that tightens and fixes the base end of the guide rod 20 to the support member 21, and fixes the guide 51 member 20 at a predetermined guide position.

Next, the operation of the article supply device configured as described above will be explained.

Now, in FIG. 1, item W1. Tray 19 containing W2
are placed at the positions shown by the two-dot chain lines, the first running member 9A is at the front end position not shown by the two-dot # line, and the second running member 9B is at the position of the first running member 9A shown by the solid line. When the chain rotates in the direction of arrow Δ from the state (hereinafter referred to as the standby position), both running members 9A and 9B are always moved in the direction of arrow A at equal intervals. Both running members 9A, 9B
As the trays 19 move, each tray 19 is pushed and transferred by the transfer portions 11 of the traveling members 9A and 9B.

During this transfer, the lower surface of each tray 19 is transferred while slidingly contacting the upper surface of the anti-slip band 18, so the anti-slip band 18 prevents the tray 19 from slipping too much and shifting in the left-right direction, and provides appropriate sliding resistance. It will be transferred smoothly. Also, in the unlikely event that 1 item -6- item W1. For some reason, W2 becomes, for example, item Wl.

Even if W2 deviates in the left-right direction due to improper placement, etc., the guide rod 20 corrects the movement direction to the appropriate direction.

As the first and second traveling members 9A and 9B move further to the position shown by the solid line in FIG. is supplied to the stand device. On the other hand, the tray 19 containing the item W1 is transferred to the position of the tray 19 containing the item W2, which is indicated by a chain line in FIG.

When the supply of the article W2 to the article receiving device is completed, the chain 4 is reversed. With the reversal of chain 4,
Both running members 9A and 9B start moving in the opposite direction of the △ arrow,
The engagement protrusions 13 of both running members 9A and 9B are connected to the engagement piece 16.
The traveling members 9A and 9B are brought into contact with the lower inclined surface 16a, and are tilted against the urging force of the spring 12.

-7- Due to this tilting, the transfer portions 11 of both traveling members 9A and 9B enter the transfer table 1 through the penetration groove 3 and move along the inner surface of the transfer surface 1a.

When both traveling members 9A and 9B reach the standby position, they are erected again by the biasing force of the spring 12. When the next item is placed in the position where the item W1 was placed before being stood up, the item is transferred again in the same manner as in the case described above, and the item W1 is transferred onto the pedestal device. .

In this way, in this embodiment, the anti-slip band 1 is placed on the transfer surface 1a.
8 and attach the belt 18 to the item W1. Since the tray 19 containing the W2 is moved, the tray 19 is accurately transferred to a predetermined supply position without being shifted in the left-right direction due to excessive slippage.

In addition, since the anti-slip strip 18 is made of artificial grass cut into strips, even if the bottom surface of the tray 19 is uneven, there are no protrusions, folds or hairs of the artificial grass on the inside of the four parts. This allows for efficient slip prevention.

In addition, in this embodiment, the anti-slip band 1 is used as an anti-slip member.
8 is formed by cutting artificial grass into strips, but any material may be used as long as it reduces the slippage of the tray 19, and the running surface may be covered with it like a carpet, which is outside the scope of this invention. You may change it as appropriate within the range.

As described in detail above, in the article supply 4A position where the articles placed on the transfer table-F are transferred by the traveling member that moves along the transfer table by the reciprocating mechanism, a slip prevention member is placed on the transfer surface of the transfer table. By attaching the holder, it is possible to accurately transfer the article to a predetermined supply position without causing the article to slip excessively during transfer and shift in the left-right direction, which is excellent for industrial use.
