In FIG. 5, when the first link 51 rotates 90 ° counterclockwise due to the rotation of the output shaft of the motor 38, both the second link 52 and the turning shaft 35 rotate 90 °. As a result, both the revolving unit 34 and the revolving arm 47 are rotated by 90 °, and the conveyor 36, the guide rod 31 and the tray 5 held by them are turned from the vertical direction to the horizontal direction. At this time, the peg 15 on the lower side of the peg stand 2 faces the guide rod 31 with the package P hooked. Then, when the backing plate 17 of the pusher device 16 protrudes and pushes the end of the package P as shown by an arrow, the package P is inserted into the peg portion 26 of the tray 5 while being guided by the guide rod 31 as shown by a two-dot chain line. It is. In particular, the tip of the guide rod 31 further projects beyond the center of gravity G of the package P inserted laterally into the tray 5, and the package P is prevented from dropping in the next step.

In FIG. 6, when the first link 51 rotates 90 ° clockwise due to rotation of the output shaft of the motor 38, both the second link 52 and the turning shaft 35 rotate 90 °. As a result, both the revolving unit 34 and the revolving arm 47 are rotated by 90 °, and the conveyor 36, the guide rod 31 and the tray 5 held by them are turned from the horizontal to the vertical. At this time, since the guide bar 31 protrudes from the center of gravity of the package P as shown in FIG. 5, even if the package P comes off the tray 5 due to the centrifugal force, the package P is not caught by the guide bar 31 and dropped. Then, as shown in FIG. 6, when the peg portion 26 of the tray 5 is in the vertical vertical position, the package P is in a state of being inserted into the peg portion 26 of the tray 5. Next, when the support base 32 is lowered, the pecking shaft 31 is lowered to a position away from the tray 5. And the belt 49 of the conveyor 36
The tray 5 is carried out in the direction of the arrow b in FIG. 2 and is carried on the actual tray carry-out conveyor 4 and carried out to the package inspection device, the package stocker, and the like.

Returning to FIG. 1, when the entire peg stand 2 is lowered by an interval P1 with respect to the peg stand 2 in FIG. 5, the peg 15 on the inner side of the peg stand 2 faces the guide rod 31. Then, the package P hung on the peg 15 on the middle side of the peg stand 2 is transferred by repeating the operation of FIGS. In this way, the upper, middle, lower, three rows of pegs 1
The three operations of the package transfer device 1 and the three movements of the peg stand 2 can efficiently transfer all 12 packages P to the peg stand 2 having three in three.

The peg stand 2 is not limited to the suspension type, but may be a type capable of running on the ground. In this case, the peg stand can be raised and lowered by a lifter. The number of guide rods 31 is arbitrary, and may be one. Further, even if the tray is in the horizontal direction, the peg portion does not need to be strictly changed from vertical to horizontal, and the peg portion may be set to be horizontal so that the package can be directly transferred from the peg stand. The peg stand 2 and the package transfer device 1 only need to be able to move up and down relatively, and the entire package transfer device 1 may be moved up and down. Further, the lifting mechanism 33 of the support base 32 is not limited to the one using the cylinder device, but may be one using a rack and a pinion or one using a screw shaft. Further, the link mechanism 37 for rotating the revolving unit 34 within a predetermined angle may use a gear or a chain.

[0030]

As described above, according to the first aspect of the present invention, since the tray is positioned by using the peg portion for inserting the package, only the peg portion is pushed up from below. Thus, reliable positioning around the peg portion can be performed. Further, since the tray always has the peg portion, it is not necessary to provide a special member for holding the tray on the tray, and the tray can be easily positioned. Further, when the package hung on the peg stand is pushed in, the package is inserted in the peg portion of the tray in a predetermined direction, so that there is an effect that a package reversing device or the like becomes unnecessary.

According to the second aspect of the present invention, in addition to the effect of the first aspect, the guide rod not only positions the tray but also guides the package to be inserted.

According to the invention of claim 3, claim 1 or 2
