DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is directed to a heavy rollable transport object, such as a roll of newspaper before printing, which is installed orthogonally to each other. 1, second transfer device (conveyor)
The present invention relates to a swivel transfer device for a rolled conveyed object for transferring between conveyed objects and converting the conveying direction of the conveyed object by, for example, 90 °.

2. Description of the Related Art Conventional techniques and problems Conventionally, there is an apparatus shown in FIGS. 3 and 4 as an example of a swivel transfer device for converting the transfer direction of a transferable object by 90 °.

That is, first, the transported object W linearly transported to the swivel transfer device 11 by the first transport device (conveyor) 10.
The tilting arm 15 tilts about the shaft 14 by the operation of the hydraulic cylinder 13 of the pusher 12.
Pushes while rolling. In the turning transfer device 11, the table 16 is preliminarily inclined to a downward slope (downward left in FIG. 4), the rolling of the conveyed article W is received, and the arm 18 and the shock absorber 19 having the shaft 17 as the tilt center function. The article W is received and held so as to soften the impact. After that, the turning transfer device 11 places the conveyed article W and rotates 90 ° to the right in FIG. 3 by the roller 20, and the hydraulic cylinder 21 and the cam 22 operate to move the table 16 to the shaft 23.
Is tilted in the opposite direction to the above-mentioned tilt, and by utilizing the tilt and the own weight of the conveyed object W, the conveyed object W is rolled and sent to the second conveying device (conveyor) 24. The conveyed article W is
The rolling is temporarily received by the shock absorber 26 of the stopper 25 and the arm 28 that tilts around the shaft 27, is reliably placed on the second transfer device 24, and is transferred in the direction orthogonal to the first transfer device 10. To go.

However, with the swing transfer device 11 having such a structure,
Since the pusher 12 and the stopper 25 are required for loading and unloading the transported article W, the entire transport line is complicated, a mechanism for tilting the table 16, a mechanism for rotating the table 16, and a mechanism for receiving the rolling of the transported article W. Must be provided on the lower surface of the table, and a pit 29, which is formed by deeply digging the lower surface of the table 16, is required. The opposite edge 16a is high when carrying in and low when carrying out, and in response to this, the second transfer device 10 is moved to the first transfer device.
There is a problem that it must be installed lower than 10 and that it takes time and effort for construction.

Further, as a second example of the turning transfer device, although not shown, there is a device which is installed at the orthogonal portion of the first and second conveying devices which are orthogonal to each other and which is equipped with a conveyor and rotates horizontally. The swivel transfer device stops at a position where the conveyor is aligned with the first transfer device, loads the conveyed product W onto the conveyor, and then 90 °
It rotates so that it is stopped again at a position where the second carrying-in device and the conveyor are aligned to carry out the conveyed product W. Therefore, the connection with each conveying device is not smooth, and small conveyed products are There is a problem that it is damaged by the connection.

Further, this swivel transfer device has problems that the transfer processing speed is slow, it takes a long time to transfer the transported object, and various devices are required to control the conveyor.

Means for Solving the Problems The present invention has a frame provided with a space for accommodating rolling objects to be horizontally swiveled, and a lower part of the frame is inclined downward from the inside toward the outside. An inclined portion is provided, and an arm is provided on the upper portion of the frame so as to be capable of inclining in a vertical plane. When the arm is inwardly inclined, a rolling object is held on the inclined portion and outwardly inclined. The above-mentioned problems have been solved by a rolling transfer device of a rolled conveyed object which is adapted to cause the rolled conveyed object to roll out from the inclined portion.

By the inward tilting of the arm, the transported object is rolled from the first transporting device so as to be held in the inclined portion and placed on the turning transfer device. The swivel transfer device horizontally rotates, for example, 90 ° while holding the conveyed product by the arm, and stops at the position where the conveyed product faces the second conveying device. After that, the arm tilts outward to release the hugging of the conveyed object, and the conveyed object rolls down from the inclined portion by its own weight and is transferred to the second conveying device.

As a result, the swivel transfer device swivels the transferred object from the first transfer device to the second transfer device, changes the transfer direction by 90 °, and transfers the transferred product.

It should be noted that if a roller is attached to the tip of the arm, the contact with the conveyed product becomes a rolling contact, and the occurrence of scratches on the conveyed product is suppressed.

Embodiment Hereinafter, the same embodiment of the present invention will be described with reference to the drawings.

The swivel transfer device of the present invention is a conveyor which is a conveyor installed at right angles to each other on the same horizontal plane.
It is installed inside the right-angled installation part A.

The turning transfer device 40 includes a base 43 installed on the floor and a base 43.
A support shaft 44 provided perpendicular to the support shaft 43, a substantially U-shaped frame 45 rotating about the support shaft 44, and an upper end 45 of the frame 45.
The horizontal shaft 46 provided in a, an arm 47 that tilts in a vertical plane about the horizontal shaft 46, and an air cylinder 48 that is connected to one end of the arm 47 and is installed above the frame 45. The lower portion 45b is formed with an inclined portion 49 which is inclined downward from the inner side to the outer side so as to face the roller 47a at the tip of the arm 47. The frame 45 has a space S for accommodating a rolling object. The air cylinder 48 is supported by a support shaft 48a on the frame 45 so as to swing in a vertical plane.

Further, in order to prevent the inclination of the frame 45, the frame 45 is provided with a floating rotation preventing guide roller 50 (lower left in FIG. 1), and the base 43 is provided with a receiving member 51 which is in contact with the roller 50 from above. They are provided respectively.

Further, in order to facilitate horizontal rotation of the frame 45, a sliding liner 53 made of a plate having a small friction coefficient, which is in contact with the upper surface of the ring-shaped sliding rail 52, is provided on the lower surface of the frame 45.

Further, an air cylinder 54 for rotating the frame 45 is installed on the upper surface of the base 43.

Next, the operation of the turning transfer device 40 will be described.

The swivel transfer device 40 is stopped at a position facing the first transport device 41, and the arm 47 is placed in a substantially horizontal state, which is the position indicated by the solid line in FIG. Leave it in a state.

When the transported object W is transported to the bottom of the arm 47 by the first transportation device 41, the first transportation device 41 temporarily stops. At the same time, the air cylinder 48 operates to tilt the arm 47 in the clockwise direction (inward direction) in FIG. Then, the tip roller 47a of the arm 47 pushes the side surface of the conveyed product W and rolls it toward the arm 45 so as to hold the conveyed product W. As a result, the article W is transferred from the first transfer device 41 to the inclined portion 49.

The frame 45 in which the object W is held by the arm 47 is a spindle.
The air cylinder 54 horizontally rotates about 90 ° in FIG. 2 around the center 44 and stops at a position facing the second transfer device 42.

At this stop position, the arm 47 tilts outward in the direction opposite to the tilting direction, and the hugging of the conveyed article W is released. Then, the conveyed article W rolls down the inclined portion 49 by its own weight and is placed on the second conveyor 42. At that time, in order to prevent the conveyed product W from rolling too much and passing through the second transfer device 42, the arm 47 is tilted and stopped to a position for receiving the conveyed product W. After the transported articles W are surely loaded on the second transfer device 42, the arm 47 returns to the initial position in the substantially horizontal state.
After that, the transported object W is transported by the second transport device 42, and the swivel transfer device 40 horizontally rotates in the counterclockwise direction by about 90 ° in FIG. 2 to face the first transfer device 41. Then, the standby state for receiving the next conveyed article W is set.

Although the conveyed object W has a large diameter in the above description, as shown in FIG. 1, even if the conveyed object Wa having a small diameter is operated in the same manner, the first conveyor device 41 to the second conveyor device 42. Can be transferred to.

Further, the conveyed article W is not limited to the rolled paper, and may be a rolled thin steel plate. The roller 47a is the object W to be conveyed.
It is provided at the tip of the arm that presses against the object and prevents the object W from being scratched by rolling contact with the object W, and may be omitted in the case of a hard object such as a steel plate. .

Further, although the first and second transfer devices 41 and 42 are installed at right angles to each other, they may be installed at obtuse angles or acute angles. In that case, the rotation angle of the turning transfer device 40 changes according to the installation angle.

According to the swivel transfer device 40 of the above-described embodiment, devices such as pushers and stoppers that have been conventionally required are not necessary, and the swivel transfer device itself has a simple structure, and the mechanism of the entire transfer line is simplified. To be done.

Furthermore, the pit that was required in the past is no longer necessary, and it is possible to install it on the second floor or higher of the building.

Also, since the frame 45 rotates horizontally without tilting,
The first and second transfer devices 41, 42 can be installed on the same horizontal plane, which facilitates construction.

In addition, the conventional swivel transfer device has a long rolling distance of the conveyed object (about 2.5 meters), but in the present invention, this can be shortened (0.85 meters), and the rolled paper may become loose. Even thin paper can be handled without any damage, and damage to the paper such as blurring, wrinkles, and kinks can be eliminated.

In addition, it is possible to deal with regardless of the length or diameter of the transported object.

Effect of the Invention As described above, according to the rolling transfer device of the rolling transport object of the present invention, the entire transport line is simplified, pits are not required, and it can be installed on the second floor or above of a building. Being able to transfer regardless of the size of the transported object,
