Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a kneader. More specifically, the present invention relates to a device that can be easily and safely cleaned when switching materials to be kneaded and can be made compact by reducing the overall height of the device.
[0002]
[Prior art]
In recent years, for example, with the improvement in quality and functionality of tires and other rubber products, the role played by a kneader for mixing and kneading rubber and compounding chemicals has become increasingly important.
As such a kneader, the one shown in FIG. 6 is common. This kneading machine is for mass processing, has high processing capacity, and is also called a mixer (mixer). On the other hand, the one for small amount processing is called a kneader (not shown).
[0003]
An outline of the structure of the kneader shown in FIG. 6 will be described.
The kneader includes a housing 100. A pedestal 109 is provided at the lower part of the kneader. The housing 100 has openings at the top and bottom of the internal kneading chamber 101. Two rotors 102 are provided inside the kneading chamber 100. The opening on the lower side of the kneading chamber 101 can be closed by closing the rotatable discharge door 103. Further, the opening on the upper side can be closed by closing the pressure lid 104 (floating weight). The pressure lid 104 is provided at the tip of the rod of the hydraulic cylinder unit 105 with the rod facing downward.
[0004]
The hydraulic cylinder 105 is fixed vertically to an upper portion of a hopper stand 106 provided vertically. 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 so that sliding is possible. Reference numeral 108 denotes an openable / closable hopper door for placing material, and is provided above the cylinder portion 107.
Further, the pressure lid 104 is positioned further above the lower end of the opening of the hopper door 108 during standby (the standby position is indicated by a dotted line).
[0005]
When kneading rubber or the like, the discharge door 103 is closed, the material is put into the kneading chamber 100, the pressure lid 104 is closed, and the rotor 102 is kneaded. When changing the rubber, the pressure lid 104 is raised, the discharge door 103 is opened and the kneaded rubber is discharged, and then remains attached to the inside of the kneading chamber 101, the rotor 102, the pressing surface of the pressure lid 104, or the like. Remove the rubber and add a new material.
[0006]
[Problems to be solved by the invention]
However, the conventional kneaders described above have the following problems.
That is, when a kneader is used for operations such as rubber kneading, one type of rubber is not exclusively kneaded with one kneader, but usually a plurality of types of rubber are kneaded with one kneader. It is done while switching appropriately.
When switching the rubber to be kneaded, the pressure lid 104 is raised as described above, the discharge door 103 is opened and the kneaded rubber is discharged, and then the inside of the kneading chamber 101, the rotor 102, or the pressing surface of the pressure lid 104 It is necessary to remove the rubber remaining on the surface.
[0007]
This cleaning operation is an operation in which an operator puts his hands through the upper and lower openings of the kneading chamber 101 and wipes with a cloth soaked with alcohol. However, the operation is performed in a narrow space and is difficult to perform. In particular, work from the upper opening is not accessible unless the hopper door 108 is opened and the upper body is inserted. This not only prevents sufficient cleaning, but also has a high risk of serious accidents such as the pressure lid 104 being lowered due to malfunction of the hydraulic cylinder 105 and the operator being injured.
[0008]
Further, the hydraulic cylinder 105 that lowers the pressure lid 104 to apply pressure to the rubber in the kneading chamber 101 has a vertical axis direction. That is, in the conventional kneader, the length of the housing 100 plus the total length of the hydraulic cylinder 105 and the forward / backward stroke of the rod needs to be taken in the vertical direction. For this reason, the size of the mixer increases, and a facility with a high ceiling is required to install the mixer, and the installation location is limited.
[0009]
An object of the present invention is, for example, in a kneader for mixing and kneading rubber and a compounding drug, by making it easier to clean the device when switching the material to be kneaded and to improve safety during cleaning. is there.
Another object of the present invention is to reduce the overall height of the apparatus so that it can be made compact, so that a facility with a high ceiling is not required to install the apparatus, and the installation location is limited by the ceiling height. It is to avoid.

The kneading chamber 20 is closed except for an inlet 22 and an outlet 24 described later. Further, the side surface portion 21 of the kneading chamber 20 has a structure having a curved surface with an arc-shaped cross section, and is formed so as to essentially follow the rotation trajectory of the tip of the blade portion 41 of the rotors 4 and 4a described later. A water cooling jacket 29 is provided inside the wall of each side portion 21. In the jacket 29, water is supplied by a water circulation device (not shown), and a workpiece to be kneaded and heated to high temperature and pressure can be appropriately cooled.
[0025]
Inside the kneading chamber 20, rotors 4, 4a, which are kneading members, are arranged side by side.
The rotors 4 and 4a are provided in parallel to each other so that the axial directions of the respective rotary shafts 40 are in the front-rear direction (the depth direction in FIGS. 3 to 5) and are horizontal. Protruding blade portions 41 for efficiently kneading the material are provided on the peripheral surfaces of the rotors 4 and 4a. The shape of the peripheral surface of the rotors 4 and 4a is not particularly limited as long as the materials can be efficiently kneaded.
[0026]
The rotors 4 and 4a are driven by a driving device such as a motor (not shown). The rotors 4 and 4a are meshing types (interlocked by meshing gears provided on shafts) and have a structure that can withstand high loads. The rotors 4 and 4a rotate in the same direction, but may rotate in the opposite direction, and the rotation direction is not particularly limited.
[0027]
An inlet 22 is provided in the upper part of the kneading chamber 20. The inlet 22 has a large opening so as to facilitate the charging of the material to be kneaded and the cleaning of the kneading chamber 20 and the rotors 4 and 4a, and the edge of the inlet 22 is the rotational axis 40 of the rotors 4 and 4a. It extends to the outside further from the upper position.
[0028]
Further, on the upper side of the housing 2, a curved cylinder portion 23 that communicates with the inlet 22 from the outside is provided. The horizontal cross-sectional shape of the curved cylinder portion 23 is a quadrangular shape. Of the side surfaces of the bending cylinder portion 23, the front and rear side surfaces (not shown for convenience in FIGS. 3 to 5) are flat surfaces, and the left and right side surfaces 230 and 231 shown in FIGS. 3 to 5 are curved.

The platform 1 is provided with a discharge door 3 that can block the outlet 24. The discharge door 3 is provided on an arm 30 that is attached to the base 1 by a rotation shaft 31. The shape of the surface 32 of the discharge door 3 is formed into a curved surface (an arc having the same cross-sectional shape) that is continuous with the curved surface of each side surface portion 21 of the kneading chamber 20, and the cross-sectional shape is a mountain shape with a high center. ing. Inside the discharge door 3, a water cooling jacket 39 is provided. Water is supplied into the jacket 39 by a water circulation device (not shown).
[0031]
The structure for rotating the rotating 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 is engaged with the pinion. As the rack reciprocates (advances and retreats) by the operation of the hydraulic cylinder 33, the rotary shaft 31 rotates in both forward and reverse directions. Thereby, the arm 30 rotates and the outlet 24 can be opened and closed by the discharge door 3.
[0032]
The discharge door 3 is configured to be pressed by a stopper 8 (see FIG. 1) so as not to open when closed. The stopper 8 is attached to a rod of a hydraulic cylinder 80 that is fixed horizontally on the right side of the base 1 with the rod facing leftward. A slope 81 is provided on the upper surface side of the tip of the stopper 8 so as to prevent the stopper 8 from moving when the stopper 8 is moved below the discharge door 3.
[0033]
A movable body 5 is provided on the side (side) of the base portion 1 so as to be rotatable in the vertical direction about the coaxial 50 via the shaft 50. The movable body 5 is formed in an inverted U shape (at the time of standby in FIG. 3) in a front view.
The base end portion of the movable body 5 is pivotally supported by a shaft 50 fixed to the base portion 1. Near the base end portion of the movable body 5, brackets 51 are provided at two places (parallel to the depth direction in FIGS. 3 to 5). Each bracket 51 is attached with a rod tip portion of a hydraulic cylinder 53 provided corresponding to each bracket 51 so as to be rotatable with respect to each other via a pin 52. Each hydraulic cylinder 53 is attached to the end of the pedestal 10 via the bearing 530 so that the cylinder portion can rotate as described above (see FIG. 2).
In this embodiment, a hydraulic cylinder is used as a drive source, but other actuators or motors such as an air cylinder may be employed.
[0034]
A pressure lid 6 is attached to the tip of the movable body 5 so that the cross-sectional shape is a quadrangle like the curved cylinder portion 23 and can be inserted into the curved cylinder portion 23 and slid up and down. There is a slight gap between the side surface (circumferential surface) of the pressure lid 6 and the inner surface of the curved cylinder portion 23 so that the material does not leak, and the pressure lid 6 can be smoothly fitted and slid. .
[0035]
The shape of the pressure surface 60 of the pressure lid 6 is formed into a curved surface (an arc having the same cross-sectional shape) connected to the curved surface of each side surface portion 21 of the kneading chamber 20, and the cross-sectional shape is a mountain shape with a high center. It has become. A water cooling jacket 69 is provided inside the pressure lid 6. Water is supplied into the jacket 69 by a water circulation device (not shown).
[0036]
The movable body 5 is rotated by the operation of the hydraulic cylinder 53, and the rod of the hydraulic cylinder 53 is reduced during standby, and the pressure lid 6 at the tip is removed from the upper side of the bending cylinder portion 23 and is positioned on the side ( (See FIG. 3).
Further, at the time of pressurization (at the time of kneading work), the movable body 5 is pivoted downward, and the pressurization lid 6 is inserted into the curved cylinder portion 23 from the upper opening and descends while sliding. The pressure lid 6 that has been lowered can block the inlet 22 at the top of the kneading chamber 20.
[0037]
As shown in FIG. 2, a cover 7 is attached to the upper portion of the housing 2. The cover 7 is formed of a plate body and is hollow inside. An opening 70 through which the movable body 5 can pass is provided on the left side of the cover 7. The opening 70 is formed so as to be substantially closed by the pressure lid 6 (shown in phantom lines in FIG. 1) during standby.
An upper surface plate 71 is provided near the opening 70 in the cover 7. The upper surface plate 71 is provided with a connecting pipe 72 connected to a dust collector (not shown). The connecting pipe 72 communicates with the inside of the cover 7.
[0038]
A hopper port 73 is opened to the right of the upper side of the cover 7. The hopper port 73 is provided with a folding lid 74 that can be folded and opened upward. A chute plate 75 connected to the hopper port 73 is provided at the right end of the cover 7.
[0039]
(Work)
With reference to FIG. 1 thru | or FIG. 5, the effect | action of the kneading machine A which concerns on this Embodiment is demonstrated.
At the time of standby, the rod of the hydraulic cylinder 53 is reduced, and the pressure lid 6 at the tip of the movable body 5 is located on the side of the curved cylinder 23 from the upper side. The discharge door 3 is closed and pressed by a stopper 8 (see FIG. 3). Cooling water is supplied to each jacket 29, 39, 69 and circulates.
[0040]
(1) The folding lid 74 of the cover 7 is opened, and materials to be kneaded (kneaded rubber and compounding chemical) are put into the inlet 22. At this time, even if some amount of dust such as compounded medicine is generated, it is sucked by the dust collector through the connecting pipe 72, so there is no problem in the work. Then, after the closing, the folding lid 74 is closed.
(2) Operate the hydraulic cylinder 53 to rotate the movable body 5 downward. As a result, the pressure lid 6 is inserted into the curved cylinder portion 23 from the upper opening and descends while sliding. The lowered pressure lid 6 closes the inlet 22 at the top of the kneading chamber 20 (see FIG. 4). In this state, hydraulic pressure is applied to the hydraulic cylinder 53 so that the pressure lid 6 does not rise.
[0041]
(3) The rotors 4 and 4a are driven to rotate. As a result, the materials are kneaded and the compounding agent is evenly mixed and dispersed in the rubber. By kneading the material in the sealed kneading chamber 20, the material and the inside of the kneading chamber 20 become high temperature and high pressure, but are cooled by the cooling water circulating through the jackets 29, 39, and 69, so that they relax. This reduces the burden on the machine.
[0042]
(4) When the kneading of the material is finished, the hydraulic cylinder 53 is actuated and the movable body 5 is raised and rotated, so that the pressure lid 6 comes out of the bending cylinder portion 23 and comes off from the upper side of the bending cylinder portion 23. (Standby state: see FIG. 3).
Next, the hydraulic cylinder 80 is activated and the stopper 8 is retracted, and the state where the discharge door 3 is pressed is released. Further, the hydraulic cylinder 33 is operated, the discharge door 3 is moved downward, and the outlet 24 is opened (see FIG. 5). In this state, the kneaded rubber is discharged from the outlet 24.
[0043]
The kneading operation is performed as described above. However, when the type of rubber to be kneaded (color, component, etc.) is switched, after the rubber kneaded is discharged from the kneading chamber 20, the inside of the kneading chamber 20, the rotors 4, 4a, or pressurization is performed. It is necessary to remove the rubber remaining on the pressing surface of the lid 6 and clean it.
[0044]
The cleaning work is performed in a state where the pressure lid 6 and the discharge door 3 are opened (the state shown in FIG. 5). When the inside of the kneading chamber 20 is cleaned from the lower outlet 24 side, the outlet 24 is greatly opened as described above, so that the operator can easily put his hand in, and the cleaning can be performed quickly and reliably.
Even when the inside of the kneading chamber 20 is cleaned from the upper inlet 22 side, the inlet 22 is greatly opened as described above, and the opening of the hopper port 73 (the upper edge of the chute plate 75) is also relatively low. Therefore, it is easy for an operator to put in his hand and cleaning can be done quickly and reliably.
[0045]
Further, by providing the pressure lid 6 on the movable body 5 that rotates in the vertical direction, the movement stroke of the pressure lid 6 is directed to the side instead of the vertical direction. The stop position is not on the curved cylinder part 23 but on the side.
Therefore, when cleaning is performed by putting a hand from the inlet 22 side of the kneading chamber 20, if the pressure lid 6 is kept waiting at the side, the work space is widened and the work is facilitated. Can clean enough. Further, unlike the conventional one where the standby place for the pressure lid 6 is provided above the curved cylinder portion 23, the safety at the time of cleaning is high and a serious accident does not occur.
[0046]
Further, since the hydraulic cylinder 53 for driving the pressure lid 6 is provided on the side portion of the housing 2, it is different from the conventional kneader in which the hydraulic cylinder is provided vertically along the advancing and retreating direction of the pressure lid. The overall height is low.
Therefore, the kneader 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.
[0047]
Note that the terms and expressions used in the present specification are merely explanatory and not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
[0048]
【The invention's effect】
(A) The kneader according to the present invention can take the moving stroke of the pressurizing body not in the vertical direction (vertical direction) but in the lateral direction (lateral direction). It is possible to set to the side rather than above.
Therefore, when cleaning by putting a hand from the inlet side of the housing (the inlet side of the kneading chamber), if the pressurizing body is kept waiting on the side, the work space will be widened and work will be performed. Since it becomes easy to do, sufficient cleaning can be performed. Further, unlike the conventional one where the standby place for the pressurizing body is provided above the housing, the safety at the time of cleaning is high, and a serious accident does not occur.
[0049]
(B) It is possible to provide a hydraulic cylinder or the like for driving the pressurizing body on the side, and unlike a conventional kneader in which the hydraulic cylinder or the like is provided vertically along the advancing and retreating direction of the pressurizing body. , The overall height can be reduced.
Therefore, the kneader can be made compact, a facility with a high ceiling is not required for installing the apparatus, and the installation location is not limited by the required ceiling height.
[0050]
(C) A device provided with a means for helping to prevent the discharge door from being opened when the workpiece is kneaded can be fixed more securely when the discharge door is closed and the outlet of the kneading chamber is closed. Therefore, the material to be processed can be kneaded satisfactorily.
[0051]
(D) Any one or all of the housing, the pressure lid, and the discharge door are provided with a cooling jacket. Can be adjusted.
