Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rubber coating device, a rubber coating method, and a liner adhesion device for coating an appropriate number of filaments with raw rubber material.

[Number 10 out of 31 problems to be solved with conventional technology]
Appropriate number of filaments of books (width, e.g.: 0.8-30m5)
When trying to obtain a rubber material coated with a raw rubber material, such as a tire or a narrow ribbon-like nylon band,
Conventionally, wide yarns (for example: 9
There is a method in which a band-shaped rubber-covered cloth obtained by applying rubber to a filament (00 to 1200 s+m) with a wide topping calender is slit into a desired narrow band.

However, when slitting a rubber-coated band-shaped blind fabric into a predetermined width, there is a risk of cutting or damaging the threads along with the rubber material, so narrow rubber-coated bodies (rubber-covered tape) are used. It was difficult to obtain. Furthermore, since the width of the topping calender is designed to match the maximum material width, even if a narrow blind weaving material is obtained, the work with rubber attachment is inefficient.

Therefore, the object of the present invention is to provide a rubber coating device and a rubber coating device that can easily and quickly produce a rubber coated body in which one to several dozen (appropriate number) filaments are coated with a raw rubber material. An object of the present invention is to provide a coating method.

In addition, when a rubber-coated material such as the above-mentioned rubber covering is formed, a liner such as cloth or a thin plastic plate is usually interposed between the raw rubber coverings to prevent the upper and lower raw rubber coverings from adhering to each other. The raw rubber covering is wound onto a drum, but the required length of the raw rubber covering is determined by the specifications and production volume of the product that requires it, and does not necessarily match the length of the liner.

Therefore, in the past, in such cases, the production of raw rubber coverings (rubber coating work) was stopped, a new liner was manually replaced, and production was restarted. , productivity was poor.

Therefore, another object of the present invention is to connect the liner during operation and continuously supply the liner to the winding drum for the rubber coated body without stopping the production of rubberized materials such as rubber coated bodies. An object of the present invention is to provide a liner connecting device that can be used.

[Means to solve the problem]

In order to achieve the above-mentioned object, a first invention related to a rubber coating device of the present invention is a rubber coating device that coats a suitable number of filaments with a raw rubber material; a filamentous body feeding mechanism that feeds out the filamentous body of the bobbin in a downstream direction; when the filamentous body fed out from the filamentous body feeding mechanism passes along the downstream direction, the interior of the extrusion head is adjusted according to the characteristics of the filamentous body; a small extruder that coats the filament with a raw rubber material to form a rubber coating while maintaining an optimal rubber pressure; a pull roll mechanism that pulls the rubber coating formed by the extruder in a downstream direction; a winding mechanism disposed further downstream of the pull roll mechanism and winding the rubber covering from the pull roll mechanism onto a winding drum; interposed between the winding mechanism and the pull roll mechanism; , a supply amount adjustment mechanism that adjusts the winding speed of the winding mechanism in response to changes in line speed and winding diameter; and a supply amount adjusting mechanism that is interposed between opposing upper and lower rubber coverings of the winding drum of the winding mechanism; and a liner supply mechanism that supplies a liner that does not join the upper and lower rubber coatings to the winding mechanism while the rubber coating is being wound on the winding drum.

In this case, it is preferable to provide a traverse mechanism that reciprocates the rubber coating in a direction substantially perpendicular to the running direction and winds it up on a winding drum. It is preferable to include a pull roll mechanism having a pair of upper and lower rolls disposed in the same direction, and in which the respective axes of the rolls are shifted from each other by a small angle.

A second invention related to the rubber coating device of the present invention is a rubber coating device for coating an appropriate number of filaments with raw rubber; the rotation of a screw having a screw diameter of 2011I11 or more is perpendicular to the axis of the filaments. a crosshead for extruding the raw rubber material into the cavity from the direction; a detector for detecting the rubber pressure in the crosshead; and a detector for determining the rotation speed of the screw based on the detection signal of the detector; A control mechanism that maintains the inside at an optimal rubber pressure according to the characteristics of the thread-like body; and a screw rotation motor such as a servo motor that rotates the screw based on a rotation command from the control mechanism. be.

The liner adhesion device of the present invention includes a pair of adhesion rollers each disposed near a pair of liner winding bodies that are detachably attached to a holding body; With the starting end of one liner being held by one of the holding mechanisms, when feeding out the vicinity of the end of the other liner being fed, the rollers are moved in a direction that approaches each other. and a pressing mechanism that connects the one liner held by the one holding mechanism to the liner being fed by closely contacting the liner by the roller.

[Operation] According to the first invention, one to several dozen filaments sent out from the filament supply mechanism are introduced into the extruder, and the raw rubber material is added to the filaments in the extruder. The rubber coating is coated to form a spill-free rubber coating, which is pulled against the pressure inside the extruder by a pull roll mechanism and guided downstream via a feed adjustment mechanism, which adjusts the winding speed to the line speed. The film is adjusted in accordance with the change in the winding diameter and is wound onto the winding drum of the winding mechanism. At that time, during the winding, the liner is supplied from the liner supply mechanism to the winding drum, and the liner is interposed between the upper and lower rubber coverings of the winding drum, and the upper and lower rubber coverings are not bonded. The rubber coating is sequentially wound onto a winding drum.

Further, in the case where the traverse mechanism is provided, when the rubber covering is wound around the winding drum, the rubber covering is not wound up concentrated in one place. Furthermore, a pull roll mechanism having a pair of upper and lower rolls whose axes are disposed in different horizontal planes and whose respective axes are mutually shifted by a minute angle, is equipped with a pull roll mechanism. The rubber covering does not overlap even if it is wrapped several times.

Further, according to the second invention, a screw with a screw diameter of 2 ha or more is used, and the rotation speed is such that the rubber pressure in the head is a normal value of ik that matches the characteristics of the linear body to be coated based on the detected rubber pressure. Since the shape is determined as follows, the extrusion molded product has a predetermined constant shape without a spew.

Next, according to the liner connecting device according to the present invention, when one of the liner rolls is fed out and the liner approaches the terminal end, the pair of rollers are moved in a direction toward each other by the pressing mechanism. The starting end of the liner held by one of the holding mechanisms is automatically adhered to the delivered liner by abutting each other. Therefore, by releasing the hold on the liner by the holding mechanism when the liner is bonded, one liner can be connected to the other liner without stopping the operation, and the liner can be continuously fed out to the desired length. The rubber coating can be rolled up.

〔Example〕

Examples will be described below with reference to the drawings.

Figures 1 and 2 show the entire rubber coating device according to the present invention, which coats an appropriate number of filaments 1 (see Figure 3) with raw rubber material 2 (see Figure 3). A thread-like material supplying mechanism 3 that sends out the thread-like material 1 in the downstream direction, and a rubber coating material 2 coated on the thread-like material 1 from the thread-like material supplying mechanism 3 to form a rubber coating 4 (see FIG. 3). An extruder 5 for forming the rubber covering 4, a pull roll mechanism 6 for pulling the rubber covering 4 in the downstream direction against the rubber pressure in the pressing machine 5, and a winding drum 7 for winding the rubber covering 4 from the pull roll mechanism 6. a winding mechanism 8 for taking up the rubber coating, and a supply amount adjustment device interposed between the winding mechanism 8 and the pull roll mechanism 6 to adjust the winding speed of the rubber coating 4 in accordance with line speed and changes in the winding diameter. It includes a mechanism 9 and a liner supply mechanism 11 that supplies the liner 10 interposed between the opposing upper and lower rubber coverings 4 and 4 of the winding drum 7 to the winding mechanism 8.

Thus, the filament supply mechanism 3, extruder 5, and pull roll mechanism 6 are provided on a cart 13 equipped with casters 12, and are movable.

The filament supply mechanism 3 includes a base 14 erected on a table 13, a motor (DC servo motor) 15 provided on the base 14, and a helical coupling 16 connected to the drive shaft of the motor 15. A bobbin 18 on which the filament 1 is wound is attached to the shaft 17. Note that the bobbin 18 refers to the shaft 1
The filament 1 is wound around a paper tube (not shown) inserted into the tube 7. That is, a paper tube around which the filament l is wound is inserted into the shaft 17, and air is injected to expand the expansion member within the shaft 17, causing the expansion member to protrude from the slit portion of the shirt H7. Make sure to attach the cough tube.

Further, the base 14 is provided with a tension detector 19 (;
The filamentous body 1 fed out from the feeding bobbin 18 passes through the filamentous body guide member 20 and passes through the tension detector 19 . Then, this tension detector 19 measures the tension.

Note that, specifically, for example, a tension meter is used as the tension detector 19. This tension meter includes a pair of guide rollers and a detection roller interposed between the guide rollers, and measures tension using an image sensor.

On the other hand, as shown in the line control mechanism 81 of FIG. 10, the set tension set by the setting lever 21 and the measured tension are compared and become one signal. Further, the speed command and torque command to the motor 15 directly connected to the delivery bobbin 18 are determined based on the line speed at that time, and the tension to be delivered is controlled. In other words, the DC servo motor 15 applies regenerative braking force. That is, the optimum tension can be obtained by generating torque and braking in the opposite direction to the rotational direction. In FIG. 11, 38 is a motor for rotating the pull roll mechanism 6, which will be described later, and 70 is a motor for rotating the take-up roll, which is controlled by position detection and line speed setting of the supply amount adjustment mechanism 9. This makes it possible to respond to changes in line speed and winding diameter. Further, 80 is a position detector for the lower roll 51 of the supply amount adjustment mechanism, which will be described later.

Next, as shown in FIG.
This is a small extruder having a screw diameter of 20 mm or more and capable of extruding without a spewer.
The flow guide 24 is equipped with a flow guide 24, a die 25, etc. installed in the thread body 1, and the filament 1 has the same axis.
is inserted into the axial center hole of the filament 1 and the hole of the die 25, and is rotated from a direction perpendicular to the axial center of the filament l by rotation of a screw (not shown) that is rotated by the drive of a motor 33 such as an AC servo motor. The raw rubber material 2 is the cavity 28
The teacher rubber material 2 is extruded into the thread body 1 to form a rubber covering 4, and the rubber covering 4 is extruded into the extruder 5.
go out from

Since the thickness of the coated rubber varies depending on the pressure of the rubber in the head (i.e., the extrusion speed) and the speed of the material running in the crosshead, in order to obtain an extrudate with a predetermined shape, it is necessary to It is necessary to understand this relationship and determine the pressure inside the head. Therefore, in order to keep the pressure constant, the pressure is detected and the extrusion rotation speed is controlled. Furthermore, when extruding without a spewer, the pressure inside the head changes faster than when using a spewer, so it is necessary to use, for example, an AC servo motor that has good controllability of the extruder's rotational speed. or,
As mentioned above, the extruder size, that is, the screw diameter must be selected to be 2 screws or more so that the rubber is sufficiently plasticized at the extrusion rotation speed when a predetermined head pressure is obtained.

As shown in FIG. 12, the extrusion fi5 is controlled by the control mechanism 32 independently of the line control.

That is, the head (that is, the extrusion head) 22 depends on the characteristics of the filament 1, that is, the material (nylon, aramid fiber, steel, etc. are used in the embodiment), size, shape, and configuration.
The optimum value of the rubber pressure in the extruder is different, and there is an extruder screw rotation speed setting device 29 for startup and manual operation, and a head pressure setting device 30 to set the head pressure when controlling the head pressure.
There is. During manual operation, the screw of the extruder 5 only rotates according to the speed setting, and during pressure control, the signal from the pressure detector 31 is compared with the setting signal to ensure that a constant pressure is always maintained on the extruder 5. It gives the rotation command so that the 33 is a motor such as an AC servo motor for screw rotation that can follow the rotation command.

The extruder 5 is equipped with a cart 1 as shown in FIGS. 1 and 2.
An extruder main body 35 is held by legs 34 . Furthermore, the motor 33 may be a DC servo motor or a DC motor.

Therefore, the rubber covering 4 formed in the extruder 5 is Plurono? It is pulled downstream at machine side 6, but here,
The pull roll mechanism 6 includes upper and lower rolls 36 and 37 and a motor 38 that rotates the rolls 36 and 37, and the rubber covering 4 is wound around the upper and lower rolls 36 and 37.
The filament 1 is pulled out against the rubber pressure within the head 22. That is, as shown in FIG.
Upper and lower rolls 36 and 37 are rotatably supported, and a motor 38 is mounted on a motor holder 41 attached to the base 39.
A drive shaft 38a of the motor 38 is connected to a shaft 43 of the upper roll 36 via a coupling 42. Further, a pulley 44 is fitted onto the shaft 43, and a similar pulley 46 is fitted onto the shaft 45 of the lower roll 370, and a belt 47 is stretched between the boots IJ-44 and 46. Therefore, when the motor 38 is driven, the upper and lower rolls 36, 37 rotate.

Thus, the axial center of the upper roll 36 is perpendicular to the axial center of the rubber covering, but the axial center of the lower roll 37 is slightly shifted from the axial center of the upper roll 36 in the horizontal plane. This is to prevent the filament 1 from overlapping even if the filament 1 is wound several times.

Note that it is the surface speed of the upper and lower rolls 36 and 37 that determines the line speed of this device.

Further, the winding mechanism 8, the supply amount adjustment mechanism 9, and the liner supply mechanism 11 are provided on the base 48, and the supply amount adjustment mechanism 9 adjusts the winding speed to a line speed of several 100,111 per minute. As shown in FIGS. 5 and 6, there is a roller holder 49 erected on a base 48, an upper roller 50 rotatably supported on the upper end of the holder 49, and A slide roller 51 is movably supported, and the fitting of both rollers 50, 51 1i50a, 51a...
The rubber coating 4 from the pull roll mechanism 6 is wound around the winding drum 7, and the speed of the winding drum 7 is controlled by the vertical position of the slide roller 51. In other words, the stroke of the roller 51 is several tens of centimeters. Since it is applied several times, it functions as if the stroke has been expanded several times, and even at a line speed of several hundred meters, it can sufficiently cope with speed changes and changes in the winding diameter of the winding drum 7. in particular,
In the example, the maximum speed of the rubber covering 4 is 200 m, '+
In this case, the supply amount adjustment mechanism 9 sets the change in the winding speed to 1/10, detects this, and adjusts the winding speed so that the change in speed becomes 0.

Thus, the slide roller 51 has rollers 53 that run up and down along the guide member 52 in front of the holder 49.
・Move up and down guided by.

Further, a traverse mechanism 54 is provided at the upper end of the holder 49 of the supply amount adjustment mechanism 9, and the rubber covering 4 is fed to the winding drum 7 while being traversed over the entire width of the roll. That is, the traverse mechanism 54 includes a pulley 55 on which the rubber covering 4 is guided and moved, a holder 56 that rotatably holds the pulley 55, a holding rod 57 that holds the holder 56, and a holding rod 57. The holding rod 57 reciprocates in the direction of the arrow (that is, the direction perpendicular to the running direction of the rubber covering 40) to move the pulley 55 perpendicular to the running direction of the rubber covering 4. Let me go to the direction, rubber? mff body 4 liner 10
The rubber covering 4 is traversed within its width to prevent the winding from collapsing and to increase the length of the rubber covering 4 to be wound. The length of the filamentous body is also measured.

Next, as shown in FIG. 8, the winding mechanism 8 is connected to a base 59,
It includes a winding drum holder 60 erected on the base 59, the winding drum 7 rotatably held by the holder 60, and the like.

Thus, the holding body 60 consists of a front holding part 60a that holds the front part of the drum 7, and a rear holding part 60b that holds the rear part of the drum 7. The drum 7 is inserted and fixed into the end of the section 63, and the drum 7 is held rotatably. Further, the shaft members 61 and 62 are respectively reciprocated in the axial direction as shown by the arrows by cylinder mechanisms 64 and 65, and the drano 7 is detachably attached to the holder 60.

Further, the base 59 is placed on guide members 66, 66 provided on the base 48 via intervening members 67, and a cylinder mechanism 6 provided at a lower position on the base 4.
It is connected to the piston rod 68a of No. 8 through a connecting rod 69. That is, due to the reciprocating movement of the piston rod 68a of the cylinder mechanism 68, the base 59 is moved between the guide member 66,
66, it reciprocates in a direction perpendicular to the running direction of the rubber covering 4. 70 is a motor for rotating the shaft members 61 and 62 to rotate the winding drum 7. Note that the speed of the take-up roll is determined by the line speed and the stroke of the supply amount adjustment mechanism 9.

Next, the liner supply side 11 is shown in FIGS. 1, 2, and 9.
As shown in the figure, a holder 71 erected on the base 48;
guide rollers 72 and 73 pivotally supported by the holding body 71;
A shaft member 75, 75' that rotatably supports a pair of liner winding bodies 74, 74', etc., and during operation,
A liner connection mechanism 76 is provided on the main body frame 71 for adhering the liner 10 of the other liner roll 74' to the one liner 10' when the liner 10 of one liner roll 74 runs out. is provided.

Here, the liner connection mechanism 76 includes a suppression mechanism 77, 77' consisting of a cylinder mechanism disposed on each side, two on the left and two on the left, as shown in FIGS. 2, 9, and 1O, and an adhesive roller 78.78' attached to the piston rod 77a... of the mechanism 77.77';
Due to the reciprocating movement of the pressing mechanisms 77 and 77', the left and right rollers 7
8.78' reciprocates from the state shown by the solid line to the state shown by the imaginary line. In other words, in the state shown by the imaginary lines, the left and right rollers 78, 78' are pressed against each other, and the left and right polyliners 10, 10' are adhesively connected. Further, the pressing mechanism 77, 77' is provided with a holding mechanism 8383' that can detachably hold the starting end portions of the liner windings 74, 74'. That is, the holding structure 83 includes a cylinder mechanism 84 in which a piston rod 84a reciprocates in the vertical direction, and a member 8 that receives the tip end surface of the piston rod 84a.
The starting end of the liner winding body 74 of the shaft member 75') is held between the distal end surface of the piston rod 84a and the member 85. Note that, like the holding mechanism 83, the holding mechanism 83' includes a cylinder mechanism 84.
', and the receiver consists of a member 85'. Further, in FIG. 10, 86 is a sensor for detecting the liner supply diameter of the liner wound body 74.

As shown in FIG. 10, when the liner supply diameter sensor 86 detects that the other (shaft member 75) is approaching the starting end of the liner 10 (left side in the drawing) that is being fed,
moving rollers 78, 78' toward each other;
They come into contact with each other and become in the state shown by the imaginary lines, and the starting end of one moving liner 10 is brought into close contact with the starting end of the other liner 10' and connected.

In this case, the starting end of the unfeeded liner 10' (on the right side in the drawing) is held by the holding mechanism 83', so if the holding mechanism is released when the adhesive rollers 78 and 78' move forward, 2 liners 10.10'
passes between the pair of adhesion rollers 78, 78' which are in contact with each other in an overlapping state, thereby ensuring mutual adhesion. When the liner 10 of the liner winding body 74 of the shaft member 75 is used up, the pressing mechanisms 77 and 77' are operated to return the rollers 78 and 78' to the position indicated by the solid line, and then a new liner winding body 74 is used. If the starting end of the liner roll body 74 is held by the holding mechanism 83 while the liner roll body 74 is placed on the shaft member 75, the supply of the liner 10 can be continued without stopping by operating in the same manner as described above. .

Note that an adhesive or adhesive tape is attached to the corresponding surface (m in the figure) of the liner winding body 74' near the starting end of the liner 10', and the liner 10.10 is attached with an adhesive or adhesive tape. ' is glued. Therefore, in the liner feeder mechanism 11, when the first liner winding body 7401 is used and near the end, it is connected to the adjacent liner winding body 74 during operation, and the operation is continued.

That is, when the liner 10 is used and the terminal end is near,
When the sensor 86 detects that the liner supply diameter has become smaller, the pair of rollers 78 and 78' come into close contact with each other, bonding to the liner 10 held by one holding mechanism 83' and holding both liners together. 10.10' is automatically connected during operation.

Further, the liner is a band-shaped body made of paper, cloth, polyfilm, thin metal plate, etc., and in the example, the width dimension thereof was about 100 m5+. In addition, in FIG. 9, 81
82 indicates a powder pre-ki, and 82 indicates a rotary joint.

Next, a process of coating the raw rubber material 2 onto the filament 1 using the rubber coating apparatus configured as described above will be explained.

are wound around the upper and lower rolls 36 and 37 of the pull roll mechanism 6,
While setting the feeding tension of the filament 1, the head 2
Set the rubber pressure setting value in 2.0 Next, attach the tip of the filament l to the winding drum 7 of the winding mechanism 8 via the supply amount adjustment mechanism 9 and the traverse mechanism 54 @preparation for stacking. .

And the pull roll machine fJ! 6. Drive the winding mechanism 8 to run the thread-like body 1, then start the extruder 18, and when the rubber pressure in the head 22 reaches about 90% of the set value, as shown in Fig. 1I. The control mechanism 32 shown is turned on.

When the rubber covering 4 is wound onto the winding drum 7, the liner 10 is supplied to the winding drum 7 by the liner supply mechanism 11, and the upper and lower rubber coverings 4 facing each other are
, 4, the liner 10 is interposed between them. In this case, the width of the liner 10 is about 1001111 as described above, and the width of the rubber covering 4 ranges from 1 ms or less to more than 10 mm, so the traverse mechanism 5
4, the rubber covering 4 is traversed within the width of the liner 10. Rubber covering 4 without protruding or traversing
This is because if the rubber covering 4 is wound on the winding drum 7, the rubber covering 4 may be concentrated and the winding may collapse.

In the above-described embodiment, there is only one filament L, but it is of course possible to use several filaments l.

In addition, the rubber covering body 4 has one filament 1 and the width dimension is about 0,8+m+a to 30 mm.
