In this type of rotary disk type article supply device, a large number of articles are put together on the rotary disk, but the articles are scattered on the rotary disk, and the articles do not overlap on the swivel truck and are sequentially mounted independently. It is preferable to move. If multiple articles are piled up on top of each other on a swivel track, a lot of overlapping articles will be dropped in the subsequent alignment process, which not only reduces the efficiency of alignment but also forces them to be dropped. This is because there is a risk of damage to some articles due to the damage. Therefore, it is necessary to rotate the rotating disk as slowly as possible so that the centrifugal force does not become larger than necessary.
Therefore, the shape, size, and material of the article to be supplied are various, and some of them, such as a polyethylene disk, cause a large frictional resistance on the contact surface with the rotating disk. When a large number of such articles are put together on a rotating disk, they do not easily come apart.

The tilted posture is stabilized by supporting each of them.

A rotary disk drive motor 39 is mounted on the lower surface of the mounting plate portion 31, and torque from the rotary disk drive motor 39 is transmitted to the rotary disk drive shaft 29 via a timing belt / pulley transmission system. As a result, the rotating disk 25 rotates about the axis. Due to this rotation, each position on the upper surface of the rotating disk 25 follows a circular orbit including the outer edge 27 and orbits. Then, of the inner side surfaces of the rotary container 11, the inner side surface exposed between the swivel track 21 and the rotary disk 25 acts as a fall prevention wall 19.
The rotary disk drive shaft 29 has a cylindrical shape, and both ends in the axial direction thereof are opened through. The above-mentioned support and torque transmission are realized by using the outer peripheral surface of the rotary disk drive shaft 29, and the hollow portion thereof can be used for shaft insertion.

Reference numeral 51 indicates an induction piece unit. A mounting hub 53 is provided at the center of the guide piece unit 51. The mounting hub 53 has a cap shape and a hexagonal top surface portion, and flat plate-shaped side surface portions 55 rise vertically from the edge of the top surface portion. Therefore, the side surface portions 55, 55, ... Are formed by connecting six plane portions in an annular shape.
Reference numeral 57 indicates a guide piece, and the guide piece 57 is composed of an elongated rectangular flat plate. One short edge side of the guide piece 57 is the base end side, and the plate surface on the base end side is overlapped and fixed to one side surface portion 55.

When it is determined, the shutter function is opened and the article B is inserted. As a matter of course, the articles B are put together, so that the articles B are piled up on the upper surface of the rotating disk 25.

The rotary disk type article supply device 1 of the present invention is configured as described above, and is characterized by including a guidance mechanism using a guide piece 57.
This article supply operation will be described below.
During the operation of the device, torque is transmitted to the rotary container 11, the rotary disk 25, and the guide piece 57 so as to rotate clockwise when viewed from above by the motor drive. Since the rotary container 11 and the rotary disk 25 are fixedly connected to each other on the motor side, they rotate at a set rotation speed. These rotation speeds are almost the same, and the speed is low so that the centrifugal force does not increase more than necessary. Torque is transmitted to the induction piece 57 via the permahis torque controller 47 so as to rotate clockwise. In the free state, the torque is transmitted at a speed faster than that of the rotating disk 25, and in the slip state, the torque is rotated. It rotates at the same speed as the disk 25.

In the above state, when a large number of articles B are put together on the rotating disk 25, they are in a heaping state immediately after falling on the rotating disk 25 rotating clockwise as shown by an arrow in FIG. However, the article B on the annular transfer waiting area 79 on the outer edge 27 side receives centrifugal force and is transferred to the turning track 21 by sliding movement at the transfer point 77, and after riding on the turning track 21. Is guided to the discharge path 67 according to the turning run of the turning truck 21. At that time, when the trucks are placed on the swivel truck 21 in an overlapping manner, the upper article B is dropped by the drop piece 65.

In parallel with the above, the article B located on the front side in the rotation direction of the guide piece 57 receives centrifugal force while being pushed by the plate surface 61 of the guide piece 57 from the rear side, as shown in FIGS. 5 and 6. Gradually, the guide piece 57 overcomes the load on the article B side and rotates faster than the rotating disk 25 as shown by the thick arrow. Therefore, the pile of the article B collapses and is gradually pushed out toward the outer edge 27 of the rotating disk 25 and spreads.
The outer edge 27 and the inner annular portion connected to the outer edge 27 form a transfer standby area 79, which is located ahead of the tip edge 59 of the guide piece 57. The transfer standby area 79 has a width dimension such that one article B can sufficiently pass through.

The guide piece 57 obtains torque and sends the article B to the transfer standby area 79, but the speed of the guide piece 57 is reduced to the same speed as that of the rotating disk 25 by inserting the perm hiss torque controller 47. If the transfer standby area 79, which is the destination of the transfer, is available, it can be sent by pushing out the article B, but if it is not available, the location is already available. It is not pushed back by another occupying article B and forcibly sent the article B into an overlapping state. That is, when the article B on the transfer waiting area 79 transfers to the turning truck 21 and the place becomes vacant, the subsequent article B is pushed by the guide piece 57 and sent to the transfer waiting area 79. It is possible to fill the vacant position, and a state in which the articles B are sequentially and individually sent to the transfer standby area 79 is realized.

Articles B, B, ... Are sequentially sent to the transfer standby area 79, and then the sent articles B, B, ... Are subjected to centrifugal force and sequentially become independent on the turning track 21 one by one. I will transfer with. Taking advantage of the low-speed rotation of the rotary disk 25 and the swivel track 21, the article B is transferred independently, and it is possible to supply the articles B in an aligned manner without deteriorating the efficiency of the alignment.
Further, since the three guide pieces 57 are used, the articles B, B, ... Are divided into three areas and placed on the rotating disk 25, and the articles B, B, ... The range of torque fluctuation, which is affected by the number of, is kept small, which helps to realize the above-mentioned gentle operation.
Since the set speed of the rotary container drive motor 23, the rotary disk drive motor 39, and the induction piece drive motor 45 can be adjusted, it can be optimized according to the actual shape / size and material of the article B. ..

Further, the timing of charging by the charging chute 75 is performed by using the speed detection pulse generator 49, and since the article B on the rotating disk 25 is transparent, the article B is transparent, so the article is used by using an optical sensor. It is possible to achieve a more accurate input timing than detecting B.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and the invention can be made even if there is a design change within a range not deviating from the gist of the present invention. included.
For example, it is possible to increase the number of guide pieces by exchanging the guide piece units.
