(Problems to be Solved by the Invention) However, in the above-described conventional rotary cylindrical processing apparatus, the endless belt 6 gradually shifts in the axial direction of the roller during operation due to various causes, and the axial direction of the cylindrical body 1 is increased. Inconvenience that a part of the object to be processed 4 is relatively disengaged from the endless belt 6 due to deviation from the predetermined winding device, and the belt comes into contact with various components installed on both sides of the cylindrical body 1. Inconvenience such as breakage sometimes occurred. Therefore, in the conventional rotary cylinder type processing apparatus, it is necessary for a person to constantly monitor the operating state and stop the operation early to correct the position of the endless belt when such an abnormality, that is, the position shift of the endless belt starts to occur. There is
There was a problem of low reliability for stable continuous operation.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a rotating cylindrical processing apparatus that automatically corrects the positional deviation of the endless belt and enables stable continuous operation. It is in.

(Means for Solving the Problem) The present invention supplies at least the object to be processed to the surface of a cylindrical body that is rotatably supported and is heated or cooled, and rolls it with a pressure roll. In a rotary cylindrical processing device, which is wound around three belt supporting rollers and is pressed and transferred to the surface of the cylindrical body by an endless belt partially wound around the surface of the cylindrical body,

And an adjusting device.

(Operation) According to the rotating cylinder type processing apparatus of the present invention, when an object to be processed is supplied from the upper part to the surface of a rotating cylindrical body while being heated or cooled, the object to be processed is immediately rolled by a pressure roll to form a thin plate. Then, the endless belt is introduced into the winding area of the cylindrical body and is transferred while being in close contact with the surface of the cylindrical body, while the object to be treated is heated or cooled. When the position shift of the endless belt begins to occur during such operation, the detection device detects this and issues a signal. In response to this signal, the shaft inclination adjusting device adjusts the inclination of one belt supporting roller supporting the endless belt. When the inclination of the supporting roller changes, the moving belt tends to move in the direction opposite to the side (tensioned side) that is in strong contact with the entire width surface of the supporting roller, and therefore the supporting roller has a tendency to move. The endless belt is adjusted to the correct position by adjusting the inclination in accordance with the direction of displacement of the endless belt.

(Example) Hereinafter, the rotating cylinder type processing apparatus of the present invention will be described in more detail with reference to the examples shown in the accompanying drawings.

FIG. 1 shows a rotary cylinder type processing apparatus 10 according to an embodiment of the present invention.

The rotating cylindrical processing device 10 includes a cylindrical body 12 rotatably installed inside a casing 11. A heating or cooling medium introducing / discharging device (not shown) is provided inside the cylindrical body 12 to heat or cool the peripheral surface.
A supply unit (not shown) for supplying an object to be processed to the surface of the cylindrical body 12 is provided above the cylindrical body 12 as in the conventional rotary cylindrical processing apparatus shown in FIG. . Further, on the outer peripheral portion of the cylindrical body 12, adjacent to the object-to-be-processed supply portion and on the rotation direction side of the cylindrical body 12, the object-to-be-processed from the supply portion cooperates with the cylindrical body 12 to have a predetermined thickness. The pressure roll 13 for rolling into a sheet shape is installed.

From the installation position of the pressure roll 13 on the outer peripheral surface in the rotation direction of the cylindrical body 12 is an endless for transferring the sheet-shaped object rolled by the pressure roll 13 while being in close contact with the peripheral surface of the cylindrical body 12. The belt 14 is stretched. That is, the endless belt 14 is wound around the three guide rollers 15, 16 and 17, and at this time, the belt portion stretched between the guide roller 15 and the guide roller 16 in the endless belt 14 is a cylindrical body. Partially wrapped around twelve. In the partial winding range of the endless belt 14 around the circumferential surface of the cylindrical body 12, the guide roller 16 side is the inlet of the object to be processed and the guide roller 15 side is the outlet of the object to be processed.

A crusher 18 which is brought into close contact with the peripheral surface of the cylindrical body 12 and crushes a band-shaped object to be processed that has been heated or cooled is installed near the exit of the winding range of the endless belt 14. The crusher 18 finely crushes the object to be processed that has come out in the form of a sheet from the winding range outlet of the endless belt 14, and in order to prevent fine powder from scattering during the crushing, the cylindrical body 12 A cover 19 surrounds the side opposite to and the lower part for taking out the crushed material.

By the way, one end of the rotary support shaft 17a in the guide roller 17 supporting the endless belt 14 is supported by a bearing 17b mounted on a sliding body 21 which constitutes the shaft tilt adjusting device 20. As shown in FIG. 2, the sliding body 21 is composed of a movable cylinder portion slidably arranged on a support plate 22 using, for example, a floor plate of the present rotary cylindrical processing apparatus 10. Therefore, the piston portion 23 is located inside the sliding body 21, and both ends of the piston portion 23 are connected to one ends of piston rods 24a and 24b.
These piston rods 24a and 24b penetrate the movable cylinder portion, that is, both end plates of the sliding body 21 and extend to the outside, and each end is fixed to columns 25a and 25b standing on the support plate 22, respectively. As a result, the piston portion 23 in the sliding body 21 is held stationary, and as a result, either the right chamber 21a or the left chamber 21b in the sliding body 21 divided by the piston portion 23 is selectively pressurized with air or When pressure oil is supplied and the fluid used in the other chamber is discharged, the sliding body 21 moves left and right as seen in FIG. As a result, the bearing 17b moves in the radial direction of the guide roller 17, and the central axis of the guide roller 17 can be inclined with respect to the endless belt 14. Therefore, the inclination angle corresponds to the movement amount of the sliding body 21.

The movement of the sliding body 21, that is, whether the sliding body 21 moves to the right or to the left and the amount of movement thereof are determined by the endless belt.
It is controlled by a signal from the positional deviation detection device 26 of 14. The positional deviation detection device 26 includes an elongated sensor plate 26c called a filler palm having one end fixed to a rotation shaft 26b extending from the detection device body 26a.
6c is disposed obliquely with respect to the side edge portion of the endless belt 14 at a proper position near the guide roller 17, and the action force which is constantly pressed against the side edge portion is applied via the rotary shaft 26b and is in contact therewith. According to this position shift detection device 26,
With reference to the position of the sensor plate 26c in contact with the side edge of the endless belt 14 at a predetermined position, for example, if the endless belt 14 is displaced to the left as viewed in FIG. It rotates in the direction indicated by the arrow 27, and if it is displaced to the right, it rotates in the opposite direction, that is, in the direction indicated by the arrow 28 by its own action force, and the rotation direction and the amount of rotation of the rotary shaft 26b. The positional deviation direction and the positional deviation amount of the endless belt 14 are detected by being transmitted to the detection device main body 26b via the detection device main body 26b, and a signal corresponding thereto is emitted from the detection device main body 26a. Since such a positional deviation detecting device 26 itself is already commercially available and is known, further description of the configuration will be omitted.

In FIG. 1, reference numeral 29 is a medium introducing section for introducing a heating or cooling gas-liquid mixture into the cylindrical body 12, and 30 is a heating or cooling gas-liquid mixture inside the pressure roll 13. The medium introducing portion to be introduced, 31 is the pressure roll 13
The arm that holds the support shaft, 32 is a motor, 33 is a sprocket attached to each shaft to be rotated, 34 is a chain wound around each sprocket 33, and 35 is a dry air inside the casing 11 if necessary. The respective air supply pipes for supplying the air are shown.

Next, the operation of the rotary cylindrical processing device 10 according to this embodiment will be described.

The cylindrical body 12 and the pressure roll 13 are rotated by the driving force of the motor 32. Then, when the object to be processed is supplied from the supply unit to the upper surface of the rotating cylindrical body 12, it is immediately rolled by the pressure roll 13 to be spread into a thin plate shape, and then introduced into the cylindrical body winding range of the endless belt 14. Then, it is brought into close contact with the outer peripheral surface of the cylindrical body 12 for a predetermined rotation range, and is sufficiently heated or cooled to be processed.

The sheet-shaped object processed in this manner is a cylindrical body at the exit of the cylindrical body winding range of the endless belt 14.
12 Pressing force on the surface is released and endless belt 14
It is dropped from the crusher 18 and is crushed here.

In this way, the sheet-shaped object to be processed rolled by the pressure roll 13 is continuously fed to the endless belt 14 and the cylindrical body 12.
Endless belt 14 while being sandwiched between the surfaces and being transported
May deviate from the predetermined surface position of the cylindrical body 12 in the axial direction. When such positional displacement of the endless belt 14 occurs, the sensor plate 26c of the positional displacement detection device 26 rotates by the amount of positional displacement in the direction corresponding to the positional displacement direction of the endless belt 14, and the rotation of this sensor plate 26c Rotating shaft 26b
And is detected by the detection device main body 26a via the.

A signal from the position deviation detection device 26 is input to a control device (not shown) or the like, and the control device causes the left and right cylinder chambers 21a, 21a in the sliding body 21 of the shaft tilt adjusting device 20 to be input.
Which of the compressed air is supplied to b and the amount of the supplied air are controlled according to the input signal. As a result, the bearing 17 is adjusted by the sliding body 21 so as to adjust the endless belt 14 in accordance with the direction of displacement and the amount thereof.
b is moved in the radial direction of the guide roller 17 so that the roller 17 is inclined with respect to the surface of the endless belt 14, and as a result, the displacement of the endless belt 14 is corrected. As a result, the endless belt 14 is always automatically controlled to the proper position, and the reliability of the rotating cylindrical processing device 10 for stable continuous operation can be improved.

(Effects of the Invention) As described above, according to the rotating cylinder type processing apparatus of the present invention, the endless process of pressing the object rolled by the pressure roll against the surface of the cylindrical body for a predetermined rotation range to perform heating or cooling is performed. With respect to the belt position deviation, the position deviation detection device and the shaft inclination adjustment device automatically adjust the position, so that the device does not have to be stopped and the position of the belt changed each time as in the conventional case. The need for monitoring is eliminated and stable continuous operation is guaranteed.
