2. Description of the Related Art In recent years, as the quality of tires and other rubber products has been improved and the functionality thereof has been improved, the role of a kneader for mixing rubber and a compounding agent and kneading has become more important. As such a kneader, the one shown in FIG. 6 is generally used. This kneader is for mass processing and has a high processing capacity, and is also called a mixer (mixer). On the other hand, those for small-volume processing are called kneaders (not shown).

An outline of the structure of the kneading machine shown in FIG. 6 will be described. The kneader includes a housing 100. A base 109 is provided below the kneading machine. Housing 1
00 has openings at the top and bottom of the internal kneading chamber 101. Two rotors 102 are provided inside the kneading chamber 100. The lower opening of the kneading chamber 101 can close and close the rotatable discharge door 103. Also,
The opening on the upper side can close and close the pressure lid 104 (floating weight). The pressure lid 104 is provided at the rod tip of the hydraulic cylinder unit 105 with the rod facing downward.

The hydraulic cylinder 105 is vertically fixed to the upper part of a vertically provided hopper stand 106. The pressure lid 104 moves up and down between the hopper stand 106 and the cylinder portion 107 above the opening of the kneading chamber 101 by the operation of the hydraulic cylinder 105. A slight gap is provided between the outer surface of the pressure lid 104 and the inner surface of the cylinder portion 107 to allow sliding. Code 1
08 is a hopper door that can be opened and closed to put ingredients in,
It is provided above the cylinder portion 107. Further, the pressure lid 104 is positioned above the lower end of the opening of the hopper door 108 during standby (the standby position is shown by a dotted line).

When kneading rubber or the like, the discharge door 103 is closed, the material is put into the kneading chamber 100, and the pressure lid 1
Close 04 and knead with the rotor 102. When switching the rubber, the pressure lid 104 is raised and the discharge door 103
And the kneading chamber 101 is discharged after discharging the kneaded rubber.
The rubber remaining attached to the inside or the pressing surface of the rotor 102 or the pressure lid 104 is removed, and a new material is added.

[0006]

However, the above-mentioned conventional kneading machine has the following problems. That is, when using a kneading machine for operations such as kneading rubber, one kneading machine does not exclusively knead one kind of rubber, but usually one kneading machine kneads a plurality of kinds of rubber.

Reference numeral 1 denotes a structure having a curved surface with an arcuate cross-sectional shape, and is formed so as to essentially follow the rotation locus of the tip of the blade portion 41 of the rotors 4 and 4a described later. Inside the wall of each side part 21,
A water cooling jacket 29 is provided. Water is supplied into the jacket 29 by a water circulating device (not shown), and the object to be kneaded and brought to high temperature and high pressure can be appropriately cooled.

Inside the kneading chamber 20, rotors 4 and 4a, which are kneading members, are arranged in parallel. Rotor 4, 4a
Indicates that the axial direction of each rotary shaft 40 is the front-back direction (see FIGS.
They are provided parallel to each other so as to be horizontal (in the depth direction in FIG. 5). Protruding blades 41 are provided on the peripheral surfaces of the rotors 4 and 4a for efficiently kneading the materials. The shape of the peripheral surfaces of the rotors 4 and 4a is not particularly limited as long as the materials can be kneaded efficiently.

The rotors 4 and 4a are driven by a driving device such as a motor (not shown). Rotors 4 and 4
Reference character a is a meshing type (a gear provided on a shaft is meshed and interlocked), and has a structure capable of withstanding a high load. Also,
The rotors 4 and 4a rotate in the same direction, but may rotate in opposite directions, and the rotation direction is not particularly limited.

An inlet 22 is provided at the top of the kneading chamber 20. The inlet 22 has a large opening in order to facilitate the introduction of the material to be kneaded and the cleaning of the kneading chamber 20 and the rotors 4, 4a, and the edge of the inlet 22 is the rotor 4,
4a is further extended to the outside from the position above the rotary shaft 40.

On the upper side of the housing 2, there is provided a curved cylinder portion 23 which communicates with the inlet 22 from the outside. The horizontal cross-sectional shape of the curved cylinder portion 23 is quadrangular. Of the side surfaces of the curved cylinder portion 23, the front and rear side surfaces (not shown in FIGS. 3 to 5 for convenience) are flat surfaces, and the left and right side surfaces 230 and 231 shown in FIGS. 3 to 5 are curved.

The base 1 is provided with a discharge door 3 capable of closing the outlet 24. The discharge door 3 is provided on an arm 30 attached to the base 1 by a rotary shaft 31. The shape of the surface 32 of the discharge door 3 is the same as that of the kneading chamber 2 described above.
It is formed into a curved surface (arc shape having the same cross-sectional shape) that is continuous with the curved surface of each side surface portion 0 of 0, and the cross-sectional shape is a mountain shape with a high center. A water cooling jacket 39 is provided inside the discharge door 3. Water is supplied into the jacket 39 by a water circulation device (not shown).

The structure for rotating the rotary shaft 31 is as follows. The rotating shaft 31 is provided with a pinion (not shown). A rack (not shown) provided on the rod of the hydraulic cylinder 33 meshes with the pinion.
When the rack is reciprocated (moved back and forth) by the operation of the hydraulic cylinder 33, the rotary shaft 31 rotates in both forward and reverse directions. As a result, the arm 30 rotates, and the outlet 24 can be opened and closed by the discharge door 3.

The discharge door 3 is structured so as to be held by a stopper 8 (see FIG. 1) so as not to open when it is closed. The stopper 8 is attached to the rod of a hydraulic cylinder 80 that is horizontally fixed to the right side of the base 1 with the rod facing left. An inclined surface 81 is provided on the upper surface side of the distal end portion of the stopper 8 to prevent the stopper 8 from being caught when the stopper 8 is moved below the discharge door 3 to enable smooth operation.

On the side (side) of the base 1, a movable body 5 is provided via a shaft 50 so as to be vertically rotatable about a coaxial shaft 50. The movable body 5 has an inverted U-shape when viewed from the front (see FIG.
Waiting time). The base end of the movable body 5 is pivotally supported by a shaft 50 fixed to the base 1. Brackets 51 are provided at two locations (side by side in the depth direction in FIGS. 3 to 5) near the base end of the movable body 5. To each of the brackets 51, the rod tip end of a hydraulic cylinder 53 provided correspondingly is attached via a pin 52 so as to be rotatable relative to each other. Each hydraulic cylinder 53 is attached to the end portion of the pedestal 10 via the bearing 530 so that the cylinder portion can rotate as described above (see FIG. 2). Although the hydraulic cylinder is used as the drive source in the present embodiment, other actuators or motors such as an air cylinder may be used.

A pressure lid 6 is attached to the tip of the movable body 5 and has a quadrangular cross section similar to the curved cylinder portion 23 and is fitted in the curved cylinder portion 23 and can be slid up and down. There is a slight gap between the side surface (peripheral surface) of the pressure lid 6 and the inner surface of the curved cylinder portion 23 so that no material leaks.
Can be inserted and slid smoothly.

The pressurizing surface 60 of the pressurizing lid 6 is formed into a curved surface (arc shape having the same sectional shape) which is connected to the curved surface of each side surface portion 21 of the kneading chamber 20, and the sectional shape is centered. It is a high Yamagata. A water cooling jacket 69 is provided inside the pressure lid 6. Jacket 69
Water is supplied to the inside by a water circulation device (not shown).

The movable body 5 is rotated by the operation of the hydraulic cylinder 53, and during standby, the rod of the hydraulic cylinder 53 is contracted so that the pressing lid 6 at the tip end is located above the bending cylinder portion 23 and is located on the side portion. (See FIG. 3). Also,
During pressurization (during kneading work), the movable body 5 rotates downward, and the pressurizing lid 6 is fitted into the bending cylinder portion 23 from the upper port and slides downward. The lowered pressure lid 6 can block the inlet 22 at the upper part of the kneading chamber 20.

As shown in FIG. 2, a cover 7 is attached to the top of the housing 2. The cover 7 is formed of a plate and has a hollow inside. On the left side of the cover 7, an opening 70 through which the movable body 5 can pass is provided. The opening 70 is formed so that it can be almost closed by the pressing lid 6 (shown by phantom lines in FIG. 1) during standby.
An upper surface plate 71 is provided near the opening 70 of the cover 7. A connection pipe 72 connected to a dust collector (not shown) is provided on the upper plate 71. The connecting pipe 72 communicates with the inside of the cover 7.

A hopper opening 73 is provided on the upper right side of the cover 7 so as to open. In the hopper mouth 73,
A folding lid 74 that can be folded upward and opened is provided. A chute plate 75 connected to the hopper port 73 is provided at the right end of the cover 7.

(Operation) The operation of the kneading machine A according to this embodiment will be described with reference to FIGS. 1 to 5. During standby, the rod of the hydraulic cylinder 53 is contracted, and the pressure lid 6 at the tip of the movable body 5 is located on the side of the bending cylinder 23, which is separated from above. The discharge door 3 is closed and held down by the stopper 8 (see FIG. 3). Cooling water is supplied to each jacket 29, 39, 69 for circulation.

(1) The folding lid 74 of the cover 7 is opened, and the materials to be kneaded (rubber and compounded chemicals) are introduced into the inlet 22. At this time, even if some dust such as a mixed drug is generated, it is sucked by the dust collector through the connecting pipe 72.
There is no hindrance to the work. Then, after the insertion, the folding lid 74 is closed. (2) The hydraulic cylinder 53 is operated to rotate the movable body 5 downward. As a result, the pressure lid 6 is fitted into the curved cylinder portion 23 from the upper port and slides down. The lowered pressure lid 6 closes the inlet 22 in the upper part of the kneading chamber 20 (see FIG. 4). In this state, the hydraulic cylinder 5
Hydraulic pressure is applied to 3 to prevent the pressure lid 6 from rising.

(3) The rotors 4 and 4a are driven and rotated. As a result, the materials are kneaded and the compounded drug is evenly mixed and dispersed in the rubber. By kneading the material in the sealed kneading chamber 20, the temperature of the material and the inside of the kneading chamber 20 becomes high temperature and pressure, but since they are cooled by the cooling water circulating through the jackets 29, 39, 69, they are alleviated. Therefore, the load on the machine is reduced.

(4) When the kneading of the materials is completed, the hydraulic cylinder 53 is actuated to move the movable body 5 upward,
The pressure lid 6 comes out of the bending cylinder portion 23, and is positioned laterally apart from above the bending cylinder portion 23 (standby state: see FIG. 3). Next, the hydraulic cylinder 80 operates and the stopper 8 retracts to release the state in which the discharge door 3 is held down. Further, the hydraulic cylinder 33 operates, the discharge door 3 moves downward, and the outlet 24 is opened (see FIG. 5). Then, in this state, the kneaded rubber is discharged from the outlet 24.

The kneading operation is carried out as described above. However, when the kind (color, component, etc.) of the rubber to be kneaded is changed, after the kneaded rubber is discharged from the kneading chamber 20, the inside of the kneading chamber 20 and the rotors 4 and 4a. Alternatively, it is necessary to remove and clean the rubber remaining attached to the pressing surface of the pressure lid 6 and the like.

The cleaning operation is performed with the pressure lid 6 and the discharge door 3 open (the state shown in FIG. 5). When the inside of the kneading chamber 20 is cleaned from the lower outlet 24 side, since the outlet 24 is wide open as described above, it is easy for the operator to put his / her hand, and the cleaning can be performed quickly and surely. Even when the inside of the kneading chamber 20 is cleaned from the upper entrance 22 side, the entrance 22 is largely opened as described above, and the opening of the hopper opening 73 (the upper edge of the chute plate 75) is also relatively low. Therefore, it is easy for the operator to put his / her hand in, and cleaning can be done quickly and surely.

Further, by providing the pressure lid 6 on the movable body 5 which rotates in the vertical direction, the movement stroke of the pressure lid 6 is not in the vertical direction but in the lateral direction, so that the pressure in the standby state is applied. The stop position of the lid 6 is not on the curved cylinder portion 23 but on the side. Therefore, when putting the hand from the inlet 22 side of the kneading chamber 20 to perform cleaning, if the pressure lid 6 is made to stand by on the side, it does not get in the way and the working space becomes wider and the work becomes easier. Can be cleaned sufficiently. Further, unlike the conventional one in which the standby position of the pressure lid 6 is provided above the curved cylinder portion 23, the safety during cleaning is high and a serious accident does not occur.

Further, since the hydraulic cylinder 53 for driving the pressing lid 6 is provided on the side portion of the housing 2, the conventional kneading machine in which the hydraulic cylinder is provided vertically along the advancing / retreating direction of the pressing lid. Unlike, the total height is low. Therefore, the kneading machine A is compact, does not require a facility with a high ceiling to install the apparatus, and the installation location is not limited by the ceiling height.

It should be noted that the terms and expressions used in the present specification are merely for the purpose of explanation and are not restrictive, and terms equivalent to the above terms and expressions and expressions are not excluded. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.

[0051]

It is possible to set the stop position of the vehicle not to the upper side of the housing but to the side thereof. Therefore, when putting the hand in from the inlet side of the housing (the inlet side of the kneading chamber) for cleaning, if the pressurizing body is kept on standby sideways, it will not get in the way and the work space will be wide, and the work will be easier. As it is easier to do, sufficient cleaning can be done.
Further, unlike the conventional one in which the waiting place for the pressurizing body is provided above the housing, the safety during cleaning is high and a serious accident does not occur.
