[Conventional technology]

When conveying an annular body by a chute or a conveyor, many devices have been used to change the direction of conveyance, and examples of conventional techniques include, for example, Japanese Utility Model Application Publication No. 55-23330. There are inversion units such as the one shown in .
Additionally, devices such as manipulators are also used as orientation devices for conveyed objects depending on the purpose.

[Problem that the invention attempts to solve]

Although the above-mentioned reversing unit can arbitrarily select the conveying direction and has a simple structure, when it is used as a conveying device for different types of annular bodies with similar shapes, the annular bodies become clogged in the passageway, causing problems during conveyance. There were some points that lacked certainty, such as being the cause of Further, there was a drawback that the device could not be used as a device for rapidly changing the direction of conveyance in conjunction with a conveyance control device. Furthermore, in the case of conveyance devices such as manipulators, they have excellent functions such as reliable conveyance, versatility for handling annular objects of varying sizes and shapes, and adaptability for use in conjunction with control devices. However, the device is expensive and has the drawback of unavoidable limitations in terms of use.

are connected by a connecting pin 26 fixed to the end 22 of the rod 21 of the fluid cylinder. The connecting pin 26 is inserted into the long hole 2 bored in the side plate 27 of the frame 8.
It is now possible to move by being guided by 8.

[Effect]

The operation of the apparatus for changing the conveyance direction of an annular body according to the present invention constructed as described above will be explained below.

First, the fluid cylinder 20 is activated and the rod 21
is at the retracted end position, the end 2 of the rod 21
A pair of parallel passage plates 12 installed inside the cylindrical body 11 connected to the cylindrical body 11 by a link 23 are positioned perpendicular to the longitudinal direction of the slit hole provided at the bottom 15 of the bottomed cylindrical hole of the frame body. Retained. In this state, when the annular body 7 is carried between the pair of passage plates 12 of the movable body, the outer surface of the annular body 7 comes into contact with the bottom 15 of the bottomed cylindrical hole and the bottomed part of the frame body An annular body 7 is held within the cylindrical hole 9. Also, at the retracted end position of the rod 21 of the fluid cylinder, the end 22 of the rod 21
The stopper 18 connected to the stopper 18 stops at a raised position relative to the frame 8, and the annular body 7 supplied from the supply chute 17 is held within the supply chute 17 in a state in contact with the side surface of the stopper 18.

Next, the fluid cylinder 20 is actuated and the rod 2
1 moves forward from the backward end, the movable cylindrical body 11 connected to the rod 21 via the link 23 rotates within the bottomed cylindrical hole 9 of the frame, and at the forward end position of the rod 21, The movable body stops when the passage plate 12 of the movable body becomes in the same direction as the longitudinal direction of the slit hole 16 provided in the bottom portion 15 of the closed cylindrical hole.
An annular body 7 is placed between a pair of parallel passage plates 12 of the movable body.
When the annular body 7 is carried in, as the movable body 10 rotates with respect to the frame body 8, the outer surface of the annular body 7 rotates while being supported by the bottom 15 of the bottomed cylindrical hole and changes its posture. Immediately before the forward end of the rod 21, the annular body 7 passes through the slot 16 and falls into the guide channel 4 of the conveying device. Also, the stopper 18 connected to the end of the rod 21 of the fluid cylinder is lowered relative to the frame 8 as the rod 21 moves forward, and at the forward end of the rod 21 it stops at the lower end position shown by the chain line in FIG. do. At the lower end position of the stopper 18, the annular body 7 within the supply chute 17 moves forward until it abuts against the side plate 27 of the frame, and is supported by the upper end surface of the stopper 18.

Next, when the rod 21 of the fluid cylinder starts to retreat from the forward end position, the stopper 18 rises relative to the frame 8 while supporting the annular body 7 on the upper end surface of the stopper 18. When the rod 21 of the fluid cylinder is at the retracted end, the stopper 18 reaches the raised end;
The annular body 7 that has risen while being supported by the upper end surface of the stopper 18 climbs over the upper end of the side plate 27 of the frame body, is guided by the guide auxiliary plate 19, and is carried between the passage plates 12 of the movable body to form a bottomed cylinder. It is held at the bottom 15 of the hole.

As described above, the annular body 7 supplied from the supply chute 17 is quickly changed in its conveying direction by 90 degrees by the operation of the fluid cylinder 20 of the conveying direction changing device 2, and is transferred to the guide path 4 of the conveying device. It becomes possible.
Conversion of conveyance direction is not limited to 90 degrees;
The conversion angle can be selected by adjusting the stroke of the rod 21 of the fluid cylinder, that is, the forward and backward stop positions.

In the conveying direction changing device 3, the same reference numerals as those shown in FIGS. 1, 3, and 4 indicate that they are formed with the same structure. The conveying direction changing device 3 is installed below the guide passage 4 of the conveying device 1, and the fluid cylinder 20
At the forward end position of the rod 21, the path plate 12 of the movable body 10 is in the same direction as the conveyance direction of the guide path 4 of the conveyance device, and at the backward end position of the rod 21, the path plate 12 of the movable body is in the same direction as the conveyance direction of the guide path 4. It is perpendicular to the direction. The guide passage 4 has a shape in which the bottom is not provided in the part where the upper end surface of the frame body 8 comes into contact and the part where the upper end part 13 of the passage plate 12 of the movable body approaches and rotates. A discharge chute 29 is fixedly installed below the frame 8, and the conveyance direction of the discharge chute 29 is arranged to coincide with the longitudinal direction of the slit hole 16 provided in the bottom 15 of the cylindrical hole with a bottom. Reference numeral 30 denotes a side plate fixed to the side surface of the frame 8, and the side plate 30 is provided with a long hole 31 for guiding the end 22 of the rod 21 of the fluid cylinder.
