Here, the positioning device 10 for a container with a handle will be explained in detail based on FIGS. 2 to 4. Reference numeral 13 denotes a column erected on the machine base 4, and a substantially disc-shaped cam plate 1 is attached to the upper part via a mounting member 14.
5 are arranged. As shown in FIG.
Circumferential cam 1 with 3rd circumference having a larger diameter than other parts
6 is formed.

Reference numeral 17 denotes a rotation axis of the star wheel 5, and around this rotation axis 17, the star wheel 5 is arranged, in which support recesses 18 for supporting the containers A to be transported are formed at predetermined intervals. Further, on the upper part of the rotating shaft 17, engaging arms 19 that engage with the handle B of the container A to be transported to determine the position of the handle B are provided at positions corresponding to the respective support recesses. A pair of rotating rollers 20, that is, a contact portion that allows contact rotation of the container, is provided at the tip of each engaging arm 19, and a recess formed between the pair of rollers 20, that is, between these rollers 20, Handle B of container A
can be engaged. The lower surface of each engaging arm 19 is connected to the upper surface plate 5a of the star wheel 5.
The cam follower 22 is slidably supported by a support protrusion 21 fixed to the cam 16, and a cam follower 22 that engages with the cam 16 is provided on the upper surface. Each engaging arm 19 has a circular hole 23 bored in the center and a rotating shaft 1.
The spring 2 loaded between the cylinder 24 fitted in the spring 7
5 is constantly urged outward in the radial direction. Therefore, the engaging arm 19 is configured to be able to move forward and backward in the radial direction along the cam 16, that is, with respect to the container. The cam plate 15 is supported at its center by the top of the rotating shaft 17 via a bearing 26. On the other hand, 27 is a holding roller that is rotatably provided on the lower surface plate 5b of the star wheel 5 and holds the container A to be transferred.

The guide member 7 is composed of an arcuate upper and lower guide plate 28 extending approximately half the circumference, and a friction member 29 disposed between the upper and lower guide plates 28. As shown in FIG. 4, this friction member 29 has a length spanning approximately 2/3 from the container supply side end of the guide plate 28, and has a friction material 30 made of rubber or the like provided on its surface. The inner circumferential surface of the friction material 30 projects slightly inward in the radial direction than the inner circumferential surface of the guide plate 28 . Therefore, the container A conveyed by the star wheel 5 has the star wheel 5 on the inner circumferential side.
This friction material 30 is supported on the outer peripheral side
Since it is transferred while being in contact with the roller, it is rotated by the frictional force of the friction material 30 that accompanies the transfer.

The operation of the handle-equipped container positioning device according to the above configuration will be explained. timing screw 6

At this time, the cam follower 22 of the engagement arm 19 moves from the small diameter side to the large diameter side of the cam 16, so that the engagement arm 19 is in a state where it can protrude outward. However, if the handle B is not engaged between the pair of rotating rollers 20, the rotating roller 20 interferes with the handle B or the outer peripheral surface of the container A and cannot move forward, but the container A does not move forward as described above. Since the container A is transferred while being rotated, the handle B can definitely engage between the rotating rollers 20 while the container A rotates once, and then the engaging arm 19 protrudes and the rotation of the container A is stopped. After that, the container A is moved to the center side of the star wheel 5 by the handle B.
The rotation is stopped in a state where the star wheel 5 is facing toward the star wheel 5, and the star wheel 5 is discharged onto the rotary table 8. The container A on the rotary table 8 is oriented in any direction by the rotation of the table 8, and is conveyed to a process subsequent to the labeling mechanism 9. In this way, according to the present apparatus, after the handle-equipped container A, which is transported with the handle facing in an irregular direction, is positioned in a certain direction, a process such as labeling can be performed.

Next, a second embodiment of the present invention will be described with reference to FIG. Descriptions of parts having the same configuration as those in the first embodiment will be omitted. In the figure, 40
is a disc-shaped cam plate provided above the star wheel 5, and the outer periphery of the lower surface of this cam plate 40 has an inclined surface part on the guide member 7 side, that is, on the left side in FIG. 5, and the other part is a horizontal surface. A cam surface 41 is formed.

On the other hand, the upper surface plate 5a of the star wheel 5 is provided with an engaging arm 19 that can swing around the pin 42 as a fulcrum. The engaging arm 19 includes an engaging portion 44 supported by an upright portion 43 provided on the outer peripheral side of the fulcrum 42, that is, on the side facing the container A, and a horizontal portion extending horizontally toward the inner peripheral side of the fulcrum 42. 45 and a cam follower 46 provided thereon. As shown in FIG. 6, the engaging portion 44 has a contact portion on the side facing the container A that contacts the outer periphery of the container A to allow rotation of the container, that is, an arc-shaped peripheral surface 47, and the peripheral surface thereof. 47 has an engaging recess 4 that engages with the handle B.
8 is formed. A spring 50 is elastically loaded between the support plate 49 which is erected slightly inwardly from the fulcrum 42 of the star wheel top plate 5a and the back surface of the upright portion 43, and this spring 50 causes the engagement portion 44 to The cam follower 46 is constantly urged downward and upward. Therefore, when the engaging portion 44 engages the handle B of the rotating container A when the cam follower 46 is located on the inclined side of the cam surface 41, the engaging arm 1
9 swings to stop the rotation of the container A, and the container A can be transported with the handle B positioned in a predetermined direction.
