Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary cylinder type processing apparatus, and more specifically, it supplies synthetic resin, crushed fish and meat products to be cooled or heat-treated in an appropriate form such as a sheet. The present invention relates to a device that presses against the surface of a rotating cylindrical body that is being cooled or heated to perform processing.

[0002]

2. Description of the Related Art Conventionally, this type of device has been used as a cooling device which is a part of a crushing device in the manufacturing process of thermoplastic and thermosetting synthetic resins and the like. It is disclosed in Japanese Patent No. 225882. The conventional rotary cylinder type processing apparatus described in this publication has a cylindrical body 1 rotatably supported as shown in FIG. 9 and a cooling or heating mechanism 2 for cooling or heating the cylindrical body 1. And a supply unit 3 for supplying the object to be processed to the surface of the cylindrical body 1, and an object 4 to be processed which is disposed adjacent to the supply unit 3 and comes out of the supply unit, is pressed against the surface of the cylindrical body 1 and rolled. The pressure roll 5 and an endless belt 6 which is stretched along the outer periphery of the cylindrical body 1 and transfers the object to be treated 4 supplied to the surface of the cylindrical body 1 while being in close contact with the cylindrical body 1.
It was mainly composed of and.

By the way, as shown in FIG. 10, the endless belt 6 is made of a belt-shaped belt formed by weaving glass fibers 6a, which is coated with fluororesin. A reinforcing plate 7 (made of the same material as the belt) is fixed to the back surface (the surface on the side not contacting the object to be processed 4) with an adhesive 8 such as a heat seal film type binder or a coating type binder so as to straddle the abutting portion. Was formed.

[0004]

However, in the above-described conventional rotary cylindrical processing apparatus, the endless belt 6 has the glass fiber 6a inside which is exposed at the end butting surface when forming the endless belt 6 on the surface side in a fluffy manner. There is a problem that the object to be treated adheres to the fluff 6b and grows. Especially, the endless belt 6 is attached to the pressure roll 5
If the object 4 to be processed is a molten resin, for example, the resin in a molten state immediately contacts the endless belt 6, so that this phenomenon occurs remarkably and the object 4 is evenly processed. Since it becomes impossible to send it out of the cylindrical body 1 as a plate-shaped body having a uniform thickness, the endless belt 6
There was a problem that the machine had to be stopped frequently in order to remove the resin adhering to the seam.

An object of the present invention is to solve the above-mentioned conventional problems and uses an endless belt formed by abutting and connecting both ends of a belt-shaped belt portion containing glass fibers inside. However, it is an object of the present invention to provide a rotating cylinder type processing apparatus which does not cause adhesion of an object to be processed to the belt joint and has high joint strength at the joint.

[0006]

According to the present invention, there is provided a rotary cylinder type processing apparatus for carrying out transfer processing of an object to be processed while closely contacting the surface of a cooled or heated rotary cylinder with an endless belt, wherein the endless belt is made of glass fiber. Of the at least one belt-shaped belt portion formed by coating with a fluororesin, the non-linear end portions of the belt-shaped portion are intermeshed with each other and butted against each other, and the rotary cylinder of the object to be processed is laid across the butted portion. It is characterized in that a thin fluorocarbon resin sheet is fixed to the surface of the body that is pressed against the body.

[0007]

According to the rotary cylinder type processing apparatus of the present invention, the object to be processed is transferred while being sandwiched between the endless belts and in close contact with the outer peripheral surface of the cylindrical body, while being subjected to cooling or heating operation from the cylindrical body. Finally, it is cooled or heated to a predetermined temperature. At that time, in an endless belt in which both ends of a belt-shaped belt with glass fibers inside are butted against each other, the belt joint should straddle the butted portion on the surface (the surface on the side where the workpiece is in contact) side. The adhered thin fluororesin sheet hides the fluff of the glass fiber protruding from the joint to the surface side, and prevents the fluff from directly contacting the object to be treated. Moreover, since the sheet covering the fluff is formed to be very thin, the portion of the object sandwiched between the endless belt and the cylindrical body where the sheet is located in the object to be processed having a certain thickness by the pressure roll is sandwiched. It is possible to obtain an object having a substantially uniform thickness as the object to be processed which is cooled or heated by the cylindrical body without giving a large change in the thickness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The rotary cylinder type processing apparatus of the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 2 shows a rotary cylinder type processing apparatus 10 according to an embodiment of the present invention. The rotating cylindrical processing device 10 includes a casing 1
A cylindrical cooling or heating medium inlet 13 rotatably installed inside 1 is provided to cool or heat the outer peripheral surface. A supply unit 15 that supplies the object to be processed 14 to the surface of the cylindrical body 12 is installed above the cylindrical body 12.

Further, on the outer peripheral portion of the cylindrical body 12, adjacent to the supply portion 15 and on the rotational direction side of the cylindrical body 12, the object 14 to be processed, which has come out of the supply portion 15, is pressed against the surface of the cylindrical body 12 and rolled. A pressure roll 16 is installed. As shown in FIG. 3, the pressure roll 16 has a center support shaft 17 supported by a bearing 19 attached to an intermediate portion of an arm 18, one end of which is provided with the shaft 2.
It is rotatably supported by a fixed portion such as the casing 11 by 0.

As a result, the pressure roll 16 swings the arm 18 about the shaft 20 so that the cylinder 1
Move closer to 2. The other end of the arm 18 is attached to a support plate 21 attached to a fixed portion such as the casing 11 by bolts 22 and 23 screwed so that its position and pressing force can be adjusted. That is, FIG.
When the space adjusting bolt 22 is moved up and down, the pressure roll 16 moves up and down with respect to the cylindrical body 12, and the space between them can be adjusted, and when the pressing force adjusting bolt 23 is moved up and down, the repulsive force of the spring 24 is adjusted. It is possible to adjust the pressing force of the pressure roll 16 against the object to be processed 14.

An endless belt 25 for transporting the object to be processed 14 rolled by the pressure roll 16 is stretched around the outer peripheral surface of the cylindrical body 12. That is, the endless belt 25 is wound around the drive roller 26, the two guide rollers 27, and the pressure roll 16, and at that time, the belt stretched between the drive roller 26 and the pressure roll 16 in the endless belt 25. The part is partially wrapped around the cylinder 12.

Since the endless belt 25 is wound around the guide roller 27 including the pressure roll 16 as described above, the object to be processed 14 discharged from the supply unit 15 is
Does not directly contact the pressure roll 16 and is not rolled, but is rolled through the endless belt 25.
However, the pressure roll 16 that the object to be processed 14 receives
Even if the endless belt 25 is interposed, the pressing force by is no different from that when it is directly pressed.

By the way, as shown in FIG. 1, the endless belt 25 has a total thickness of 0.5 to 7 mm in which a fluororesin 28b is laminated on a sheet-like material in which glass fibers 28a are woven and woven.
Both ends of a single cloth belt portion (single belt) 28 are connected to each other, and the connecting portion is configured as a belt joint 29. In this belt joint 29, both ends of the belt portion 28 are formed in a non-linear shape, that is, in this embodiment, as shown clearly in FIG. 4, a large number of protrusion portions 30 provided at intervals are provided. The shape of the portion 30 has a half-mayle shape, and the spacing portion 31 between them also has the same half-mayle shape with the orientation reversed, so that the protrusion portion 30 at one end of the belt portion meshes with the spacing portion 31 at the other end. It is configured by being fitted and connected to.

A reinforcing plate similar to the conventional one, which covers the belt joint 29 on the back surface of the belt joint 29, that is, the surface on the side not contacting the object to be treated 14 (of the same material as the belt portion 28).
7 are fixed by an adhesive 8 to connect them, and a thin fluororesin sheet 32 is further fixed on the surface by an adhesive.
This thin fluororesin sheet 32 has a thickness of about 0.12.
The length L (FIG. 1) of 5 mm along the longitudinal direction of the belt 25 is preferably about 100 mm to 300 mm.

In FIG. 2, reference numeral 33 is a cylindrical body 1.
The object to be processed 14 that has been pressed and moved by the endless belt 25 on the outer peripheral surface of the second member 2 moves out of the winding range of the endless belt 25 and should go to the crusher 34, while remaining in close contact with the outer peripheral surface of the cylindrical body 12. In this case, a scraper for removing this is shown.

Next, the operation of the rotary cylinder type processing apparatus 10 according to the above embodiment will be described. In the description of this operation, it is assumed that the rotary cylindrical processing device 10 is used as a cooling device which is a part of the crushing device in the synthetic resin manufacturing process. Therefore, the object to be processed by the device 10 means a synthetic resin in a molten state.

Inside the cylindrical body 12, a cooling medium introducing port 13 is provided.
A liquid or gaseous cooling medium usually used as a cooling medium, such as water, an ethylene glycol aqueous solution, a calcium chloride aqueous solution, freon gas, or ammonia gas, is introduced, and the outer peripheral surface of the cylindrical body 12 is cooled from the inside. The molten resin 14 supplied from the object supply unit 15 to the surface of the cylindrical body 12 moves in accordance with the rotation of the cylindrical body 12, and is a pressure roll 16 and an endless roller to make the thickness uniform so as to prevent uneven cooling. The belt 25 is rolled with the belt 25 interposed therebetween, sandwiched by the endless belt 25 as it is, and transferred while being in close contact with the outer peripheral surface of the cylindrical body 12. During that time, the molten resin 14 is cooled by the cylindrical body 12.

At this time, in the endless belt 25, the belt joint 29 at the time of forming the endless belt 25 has a thin fluororesin sheet 3
Since it is covered with 2, the fluff of the glass fiber 28a protruding from the belt joint 29 to the surface is the fluororesin sheet 3 concerned.
Since it is hidden by 2 and contact with the object to be processed 14 does not occur, adhesion of the object to be processed 14 does not occur at this portion.

Next, the resin 14 in the solid state, which has come out of the winding range of the endless belt 25 around the cylindrical body 12, is finely crushed by the crusher 34 and is housed in the receiving groove 35. Then, the crushed resin pieces in the receiving groove 35 are discharged to the outside of the casing 11 by the rotation of the screw conveyor 36. In addition, the endless belt 25 includes the cylindrical body 1.
If a speed difference is generated between the two, the resin 14 that is the object to be processed may be displaced or broken, so that a drive device (not shown) that drives the belt 25 via the drive roller 26 The traveling speed is controlled so as to be synchronized with the speed of the resin 14 on the surface of the cylindrical body 12.

Although the above description of the operation is for the case where the rotary cylinder type processing apparatus 10 is used in the synthetic resin manufacturing process, the apparatus 10 of the present invention is a heat treatment for fish or meat surimi. It can also be applied to cases such as In this case, hot water, steam,
An appropriate heating medium such as doubtham oil, SK oil, mineral oil, silicone oil, or molten salt is supplied from the heating medium inlet 13. Further, it is also effective to provide a cooling or heating mechanism inside the pressure roll 16 to cool or heat the pressure roll 16 itself.

Further, in the above-described embodiment, the endless belt 25 is one cloth-like belt portion 28, that is, a single belt, but it is formed of two or more belt portions 28 and 37 as shown in FIG. It may be configured. In this case, the structure of the belt joint of the belt portion 37 arranged on the side of the endless belt 25 which does not come into contact with the object to be processed 14 is the same as that of the belt portion 28 described above, or the linear end portions are the same as in the conventional case. It may be a match.
The reinforcing plate 7 is arranged on the surface of the belt portion 37 and covers the belt joint of the belt portion 37.

The non-linear shape of the end portion of the belt portion 28 constituting the belt joint 29 of the endless belt 25 used in the rotary cylindrical processing apparatus 10 in the above-mentioned embodiment is
As shown in FIG. 3, a large number of half-mayu-shaped projections 30 are formed with a space 31 having the same shape.
As shown in FIG. 6, an inverted trapezoidal protrusion 38 and a trapezoidal gap 39 are formed in a non-linear shape, or as shown in FIG. 7, a square protrusion 40 and a gap 41 having the same shape. It may be a non-linear shape, or a non-linear shape composed of a triangular protrusion 42 shown in FIG.

[0023]

As described above, according to the rotary cylinder type processing apparatus of the present invention, the non-linear ends of the belt-shaped belt portion containing the glass fiber are connected so as to mesh with each other. Since the thin fluororesin sheet is fixed to the surface of the joint of the endless belt (the surface on the side where the object to be processed comes into contact) so as to straddle the belt joint, the glass protruding from the belt joint to the surface side The fluff of the fiber is covered with this fluororesin sheet so that the fluff does not come into direct contact with the object to be treated. Moreover, since the sheet covering the fluff is formed to be very thin, the portion of the object sandwiched between the endless belt and the cylindrical body where the sheet is located in the object to be processed having a certain thickness by the pressure roll is sandwiched. It has an excellent effect that the object to be processed which is cooled or heated by the cylindrical body and has a substantially uniform thickness can be obtained without giving a great change in the thickness.

Further, since the belt joint of the endless belt in the rotary cylindrical processing apparatus of the present invention is constructed by connecting the non-linear belt end portions so as to mesh with each other, the joint area is large and therefore the joint area is large. The joint portion, that is, the belt joint has a large counter force against the tension, and the durability can be remarkably improved.
