Description

Coating tool and coating method

Technical Field

The present invention relates to a coating tool and a coating method.

The present application claims priority based on patent application 2018-.

Background

Conventionally, a coating tool called a slit Die (Slot Die) or the like is known. In Slot Die Coating (Slot Die Coating), as a method for discharging a Coating liquid uniformly in a Coating width direction, there is a method capable of moving a throttle lever (hook bar) into and out of a flow path and regulating a discharge amount by arbitrarily restricting the flow path. This method is used in extrusion molding or the like, as in a T-die shown in patent document 1. In the T-die, the throttle lever is operated mainly using an adjusting bolt, and the lever movement amount is controlled according to the rotation amount and the pitch of the bolt.

As in the extrusion molding die disclosed in patent document 2, measures such as accurately measuring the amount of movement of the throttle lever have been taken.

As in the die coating apparatus shown in patent document 3, a method using a micrometer head is also considered in order to adjust the movement amount of the throttle lever more finely. The die coating device comprises: a throttle lever main body which is arranged to face the coating liquid flow path and is formed by connecting a plurality of partition levers partitioned in a direction of the coating liquid flow path; and a forward/backward adjuster provided for each of the partition rods. The amount of clearance in the coating liquid flow path is adjusted for each of the partition bars by advancing and retracting each of the partition bars using each of the advance and retreat adjusters.

Patent document 3: japanese patent laid-open publication No. 2007-44643 (A)

In the die coater, the advance/retreat adjuster extends to protrude upward from the die main body. Therefore, when the device is set, a space must be secured above the device. Since a large installation space is required, it is sometimes difficult to install, and it is difficult to operate the advance and retreat adjusters during coating. Further, it is difficult to visually recognize a portion of the object to be coated with the coating liquid (hereinafter, referred to as a coating portion).

Disclosure of Invention

In view of the above, an object of the present invention is to provide an application tool capable of controlling an installation space to be small, easily adjusting a position of a throttle lever even during application, and easily visually recognizing an application portion, and an application method using the application tool.

One embodiment of the coating tool of the present invention includes: a first head member 1 and a second head member 2 which are disposed adjacent to each other in a 1 st direction and extend in a 2 nd direction orthogonal to the 1 st direction; a slit provided between an inner surface of the first head member 1 and an inner surface of the second head member 2 facing each other in the 1 st direction, the coating liquid flowing inside the slit and opening outward from between a distal end portion of the first head member 1 and a distal end portion of the second head member in a 3 rd direction orthogonal to the 1 st direction and the 2 nd direction; a throttle lever extending in the 2 nd direction in the 1 st head member and capable of protruding from the 1 st direction into the slot; and an adjustment mechanism for adjusting a protruding amount of the throttle lever protruding into the slot, the adjustment mechanism having: a shaft extending in the 1 st direction in the 1 st head member and fixed to the throttle lever; a moving portion movable in the 3 rd direction with respect to the 1 st head member; and a cam portion for converting a movement amount of the moving portion in the 3 rd direction into a movement amount of the shaft in the 1 st direction.

In this coating tool, when the moving portion of the adjustment mechanism is moved in the 3 rd direction, the shaft is moved in the 1 st direction by the cam portion. Thus, the throttle lever moves in the 1 st direction together with the shaft, and the amount of protrusion of the throttle lever into the slot can be adjusted.

According to the present invention, the adjustment mechanism can be suppressed from largely protruding from the 1 st head member in the 1 st direction. This makes it possible to reduce the installation space of the application tool in the 1 st direction, and thus to easily install the application tool. Further, the moving portion is moved by an operation or the like during the coating, and the position of the throttle lever is easily adjusted. Also, a portion (coating portion) of the coated object to which the coating liquid is to be applied is easily observed during coating. Specifically, for example, when the coating state is confirmed at the start of coating or when the coating conditions are to be adjusted, the coated portion can be easily visually recognized.

In the above-described application tool, it is preferable that the cam portion converts a movement amount of the moving portion in the 3 rd direction into a movement amount of the shaft in the 1 st direction that is smaller than the movement amount.

At this time, the cam portion controls the amount of movement of the shaft in the 1 st direction to be smaller than the amount of movement of the moving portion in the 3 rd direction, and therefore, the amount of protrusion of the throttle lever into the slot can be easily finely adjusted.

In the above coating tool, it is preferable that the cam portion includes: an inclined surface disposed on the moving portion and extending in the 1 st direction as the inclined surface extends in the 3 rd direction; and a contact portion provided on the shaft and contacting the inclined surface from the 1 st direction.

At this time, when the moving portion moves in the 3 rd direction, the contact portion is pressed in the 1 st direction by the inclined surface, and the shaft moves in the 1 st direction together with the contact portion. According to the above configuration, the amount of movement of the shaft in the 1 st direction can be further reduced, and the position of the throttle lever can be finely adjusted. Specifically, for example, the position of the throttle lever can be adjusted on the order of micrometers (in units of several micrometers).

In the above-described coating tool, the contact portion is preferably a roller rotatable on the inclined surface.

In this case, the frictional resistance between the contact portion and the inclined surface can be reduced, and the function of the cam portion can be stabilized.

In the above coating tool, it is preferable that the cam portion includes: a rotation shaft extending along the 2 nd direction; and a rotating member that is rotatable around a center axis of the rotating shaft, the rotating member including: a 1 st contact part contacting the moving part in the 3 rd direction; and a 2 nd contact portion which is in contact with the shaft in the 1 st direction.

At this time, when the moving portion moves in the 3 rd direction and presses the 1 st contact portion of the rotating member, the rotating member rotates about the rotating shaft. Thereby, the 2 nd contact portion of the rotating member pushes the shaft in the 1 st direction, and the amount of protrusion of the throttle lever into the slot is adjusted. The cam portion is provided with a simple structure, and the moving amount of the moving portion in the 3 rd direction is stably converted into the moving amount of the shaft in the 1 st direction.

In the above-described application tool, it is preferable that the adjustment mechanism includes a biasing portion that biases the shaft in the 1 st direction toward either one of the moving portion and the cam portion.

At this time, since the biasing portion maintains a state in which the shaft is biased toward either the moving portion or the cam portion, even if the moving portion moves in either the 3 rd direction, the cam portion stably acts, and the shaft stably moves in either the 1 st direction. That is, by moving the moving portion, the throttle lever can be moved forward into the slot and also moved backward from the slot. Therefore, the position adjustment of the throttle lever is easily performed. Further, the biasing force of the biasing portion can suppress the play (gap) of the cam portion, and the function of the cam portion can be stabilized.

In the above coating tool, it is preferable that a plurality of the adjustment mechanisms are provided side by side in the 2 nd direction.

At this time, the amount of protrusion of the throttle lever into the slot can be adjusted at each position in the 2 nd direction by the plurality of adjustment mechanisms. Therefore, the film thickness of the coating liquid applied to the object to be coated can be adjusted at each position in the 2 nd direction of the slit.

In the above-described coating tool, it is preferable that the coating tool further includes a fixing portion that fixes the adjustment mechanism to the 1 st head member, the adjustment mechanism includes a body portion that movably supports the moving portion in the 3 rd direction, and the fixing portion extends along the 2 nd direction and supports the body portions of the plurality of adjustment mechanisms.

In this case, the main body portions of the plurality of adjustment mechanisms are supported by the fixing portion, and the plurality of adjustment mechanisms and the fixing portion are unitized. By fixing this unit to the 1 st head member, the coating tool can be easily assembled. Further, the unit can be easily removed from the coating tool or replaced, and the time required for maintenance can be reduced. Therefore, the time for stopping the operation of the coating tool for maintenance or the like can be controlled to be small, and the coating efficiency (production efficiency) can be improved. Further, zero point alignment (positioning) of the plurality of unitized adjustment mechanisms can be easily performed, the amount of protrusion of the throttle lever into the slot can be accurately controlled, and the application accuracy can be stably improved.

In the above coating tool, the fixing portion preferably includes: a fixing rod fixed to the 1 st head member and extending along the 2 nd direction; and a main body supporting portion that is provided on the fixing lever at intervals in the 2 nd direction, and that independently supports the main bodies of the plurality of adjustment mechanisms.

In this case, the above-described operational effect of the fixing portion can be obtained by a simple configuration.

In the above coating tool, it is preferable that the fixing lever and the plurality of body supporting portions are integrally formed as a single member.

In this case, since the fixing lever and the plurality of body supporting portions are formed as a single member, the number of components of the application tool can be reduced, and the assembly can be easily performed. Further, the fixing lever and the plurality of main body supporting portions are not displaced relative to each other, and the coating accuracy can be maintained well. Moreover, the fixing rod does not need to be aligned with the plurality of main body supporting parts, and the operability during maintenance and the like is improved.

In the above-described application tool, only one fixing portion may be provided.

In this case, the number of components of the coating tool can be reduced.

In the above-described application tool, a plurality of the fixing portions may be provided in parallel in the 2 nd direction.

In this case, the fixing portion is prevented from becoming too long in the 2 nd direction, the fixing portion is easy to handle, and the application tool is easy to assemble.

In the above-described application tool, it is preferable that the moving portion is disposed on a rear end side in the 3 rd direction with respect to a connection portion between a front end surface of the 1 st head member in the 3 rd direction and an outer side surface of the 1 st head member in the 1 st direction.

In this case, the moving portion is less likely to be an obstacle when observing the coating portion. Therefore, the coated portion can be more easily seen.

In the above coating tool, it is preferable that the adjustment mechanism includes an operation portion that moves the moving portion in the 3 rd direction.

In this case, for example, a dial of the micrometer head or the like is used as the operation unit, and the operator manually operates the operation unit to move the moving unit in the 3 rd direction as appropriate. That is, by operating the operating portion, the amount of protrusion of the throttle lever into the slot can be appropriately adjusted.

In the above coating tool, it is preferable that the adjustment mechanism has a driving section that drives the moving section in the 3 rd direction.

In this case, for example, a motor of an electric linear actuator is used as the driving unit, and the driving unit is remotely operated by a control unit or the like electrically connected to the driving unit, whereby the moving unit can be appropriately moved in the 3 rd direction. That is, the amount of protrusion of the throttle lever into the slot can be appropriately adjusted by remote operation.

The coating tool preferably includes: a coating film thickness detection mechanism for detecting the film thickness of the coating liquid coated on the coated object from the narrow slot; and a control unit for moving the moving unit in the 3 rd direction by the driving unit so that the film thickness is within a predetermined range, based on a detection result of the coating film thickness detecting unit.

In this case, the thickness of the coating liquid applied to the object is automatically limited to a predetermined range, and the coating accuracy can be stably improved.

In addition, an aspect of the present invention is a coating method for coating a coating liquid on a coating object using the coating tool, wherein a plurality of the adjustment mechanisms are arranged in parallel in the 2 nd direction, data of a plurality of positions in the 2 nd direction and data of each of the film thicknesses at the plurality of positions are continuously acquired by the coating film thickness detection mechanism, the data of the positions and the data of the film thicknesses are collected to an external server via a network, a difference between the data of the film thicknesses and data of a preset reference film thickness is calculated, the difference is compared with a preset threshold value, and when the difference exceeds the threshold value, the moving unit of the adjustment mechanism closest to the position exceeding the threshold value in the 2 nd direction is driven by the driving unit in the 3 rd direction, adjusting a protruding amount of the throttle lever protruding into the slot so that the difference is below the threshold value.

According to the coating method of the present invention, the coating accuracy can be stably improved by automatically equalizing the film thickness of the coating liquid applied to the object to be coated at each position in the 2 nd direction.

According to the application tool and the application method of one aspect of the present invention, the installation space can be controlled to be small, the position of the throttle lever can be easily adjusted even during application, and the application portion can be easily visually recognized.

Manifold 4 is disposed between head 1 and head 2 members 1 and 2. The manifold 4 is a space (chamber) located between the head members 1 and 2, and temporarily holds the coating liquid inside. The coating liquid flows into the manifold 4 from the 1 st coating liquid supply passage (not shown) and the 2 nd coating liquid supply passage 2g, is temporarily held in the manifold 4, and flows to the slit 5. That is, the coating liquid flows through the manifold 4.

In the present embodiment, the manifold 4 is in the form of a groove that is recessed in the 1 st direction from the inner surface 2a of the 2 nd head member 2 and extends in the 2 nd direction. The manifold 4 is recessed from the inner side face 2a to the lower side. The length of the manifold 4 in the 2 nd direction is shorter than the total length of the 2 nd head member 2 in the 2 nd direction. The manifold 4 is not opened to the left side face 2e and the right side face 2f of the 2 nd head member 2. As shown in fig. 3, the manifold 4 has a substantially semicircular shape when viewed in a cross section perpendicular to the 2 nd direction.

[ Slot ]

The slot 5 is provided between the inner side surface 1a of the 1 st head member 1 and the inner side surface 2a of the 2 nd head member 2 which are opposed to each other in the 1 st direction. That is, the slit 5 is formed between the inner surface 1a of the 1 st head member 1 and the inner surface 2a of the 2 nd head member 2 which face each other in the 1 st direction. The coating liquid flows through the inside of the slit 5. The slot 5 opens outward in the 3 rd direction from between the front end (toe portion) of the 1 st head member 1 and the front end (toe portion) of the 2 nd head member 2. The front end portion (opening portion) of the slot 5 is disposed between the front end portion of the 1 st head member 1 and the front end portion of the 2 nd head member 2 in the 1 st direction, and opens toward the object to be coated on the front end side. The rear end of the slot 5 communicates with the manifold 4. Both ends of the slit 5 in the 2 nd direction are defined by the pair of 1 st portions of the gasket member described above.

[ throttle lever ]

The throttle lever 6 is made of, for example, stainless steel. The throttle lever 6 extends in the 2 nd direction in the 1 st head member 1, and is capable of protruding from the 1 st direction into the slot 5. The throttle lever 6 projects toward a portion of the slot 5 located between the manifold 4 and a front end portion (opening portion) of the slot 5 in the 3 rd direction. In the illustrated example, the throttle lever 6 can project into the slot 5 near a rear end portion of the slot 5 connected to the manifold 4. The throttle lever 6 adjusts the flow rate of the coating liquid flowing from the manifold 4 to the tip of the slot 5 in the slot 5.

The throttle lever 6 has a square bar shape extending in the 2 nd direction, and one throttle lever 6 is provided in the present embodiment. The length of the throttle lever 6 in the 2 nd direction is shorter than the total length of the 1 st head member 1 in the 2 nd direction. The length of the throttle lever 6 in the 2 nd direction is substantially the same as the length of the manifold 4 in the 2 nd direction and the length of the slot 5 in the 2 nd direction. The throttle lever 6 is received in the 1 st recess 11 of the 1 st head member 1. The throttle lever 6 faces the inner surface 2a of the 2 nd head member 2 with a gap therebetween in the 1 st direction.

The throttle lever 6 slides in the 1 st direction in the 1 st recess 11. In the state shown in fig. 4, the lower surface of the throttle lever 6 is disposed at the same position as the inner surface 1a of the 1 st head member 1 in the 1 st direction. That is, the lower surface of the throttle lever 6 and the inner surface 1a of the 1 st head member 1 are flush with each other. In the state shown in fig. 5, the lower surface of the throttle lever 6 projects below the inner surface 1a of the first head member 1. The throttle lever 6 moves in the 1 st direction in the 1 st head member 1, thereby changing the amount of projection of the throttle lever 6 into the slot 5, and changing the internal dimension of the slot 5 in the 1 st direction.

[ adjusting mechanism ]

As shown in fig. 4, the moving unit 18 includes a micrometer head shaft 18a and a pressing block 18 b.

The micrometer head shaft 18a has a shaft shape extending in the 3 rd direction. The micrometer head shaft 18a protrudes from the micrometer head main body 17a toward the tip side. The micrometer head shaft 18a is supported by the micrometer head main body 17a so as to be movable in the 3 rd direction.

The pressing block 18b has a substantially rectangular parallelepiped shape. The pressing block 18b is fixed to the micrometer head shaft 18 a. The pressing block 18b is connected to the tip end of the micrometer head shaft 18a and is located on the tip end side of the micrometer head shaft 18 a. The pressing block 18b is disposed so as to overlap the shaft 15 and the throttle lever 6 when viewed from the 1 st direction.

The cam portion 19 converts the movement amount of the moving portion 18 in the 3 rd direction into the movement amount of the shaft 15 in the 1 st direction. Specifically, the cam portion 19 converts the movement amount of the moving portion 18 in the 3 rd direction into the movement amount of the shaft 15 in the 1 st direction, which is smaller than the movement amount.

The cam portion 19 has an inclined surface 19a and a contact portion 19 b.

The inclined surface 19a is disposed on the moving portion 18 and extends in the 1 st direction as it goes toward the 3 rd direction. The inclined surface 19a is disposed on a surface of the pressing block 18b facing the 1 st direction. In the present embodiment, the inclined surface 19a is disposed on the lower surface of the pressing block 18 b. The inclined surface 19a extends upward toward the front end side. In the inclined surface 19a, the amount of displacement in the 1 st direction per unit length along the 3 rd direction (i.e., the slope with respect to the horizontal direction) is constant over the entire length of the inclined surface 19a in the 3 rd direction. The inclined surface 19a is flat and inclined with respect to the 3 rd direction.

The contact portion 19b is provided on the shaft 15 and contacts the inclined surface 19a from the 1 st direction. The contact portion 19b is provided at the upper end portion of the shaft 15.

The biasing portion 21 biases the shaft 15 in the 1 st direction toward one of the moving portion 18 and the cam portion 19. In the present embodiment, the biasing portion 21 biases the pressing block 18b of the moving portion 18 and the inclined surface 19a of the cam portion 19 in the 1 st direction with respect to the shaft 15. Specifically, the biasing portion 21 biases the shaft 15 upward toward the pressing block 18b and the inclined surface 19 a.

The operation portion 22 rotates with respect to the micrometer head main body 17a about an unillustrated micrometer head center axis extending in the 3 rd direction. The operation unit 22 is, for example, a dial of a micrometer head.

The operation portion 22 rotates around the micrometer head center axis with respect to the micrometer head main body 17a, whereby the micrometer head shaft 18a moves in the 3 rd direction with respect to the micrometer head main body 17 a. That is, the operation portion 22 moves the moving portion 18 in the 3 rd direction with respect to the body portion 17 and the 1 st head member 1. When the operation portion 22 is rotated to one side around the center axis of the micrometer head with respect to the micrometer head main body 17a, the moving portion 18 moves to the leading end side in the 3 rd direction. When the operation portion 22 rotates to the other side around the micrometer head center axis with respect to the micrometer head main body 17a, the moving portion 18 moves to the rear end side in the 3 rd direction.

[ shade ]

As shown in fig. 2, the cover 8 is detachably attached to the 1 st head member 1. The cap 8 is preferably detachable from the first head member 1 even during coating. The cover 8 is, for example, in the form of a box with a top, or the like. The cover 8 covers the moving portion 18, the cam portion 19, the upper end portion of the shaft 15, the 2 nd recessed portion 12, and the like of the adjustment mechanism 7 from the upper side in the 1 st direction, both sides in the 2 nd direction, and both sides in the 3 rd direction.

[ Effect of the present embodiment ]

In the coating tool 10 of the present embodiment described above, as shown in fig. 4 and 5, when the moving portion 18 of the adjustment mechanism 7 is moved in the 3 rd direction, the shaft 15 is moved in the 1 st direction by the cam portion 19. Thereby, the throttle lever 6 moves in the 1 st direction together with the shaft 15, and the amount of projection of the throttle lever 6 into the slot 5 can be adjusted.

According to the present embodiment, the adjustment mechanism 7 can be suppressed from protruding greatly in the 1 st direction from the 1 st head member 1. This makes it possible to reduce the installation space of the application tool 10 in the 1 st direction, and thus the application tool 10 can be easily installed. Further, the moving portion 18 is moved by an operation or the like during the coating, and the position of the throttle lever 6 is easily adjusted. Also, a portion (coating portion) of the coated object to which the coating liquid is to be applied is easily observed during coating. Specifically, for example, when the coating state is confirmed at the start of coating or when the coating conditions are to be adjusted, the operator can easily visually recognize the coating section through the space above the adjustment mechanism 7.

In the present embodiment, the cam portion 19 converts the movement amount of the moving portion 18 in the 3 rd direction into the movement amount of the shaft 15 in the 1 st direction, which is smaller than the movement amount.

At this time, the amount of movement of the shaft 15 in the 1 st direction is controlled to be smaller than the amount of movement of the moving portion 18 in the 3 rd direction by the cam portion 19, and therefore, the amount of protrusion of the throttle lever 6 into the slot 5 can be easily finely adjusted.

In the present embodiment, the cam portion 19 has the inclined surface 19a and the contact portion 19b, and when the moving portion 18 moves in the 3 rd direction, the inclined surface 19a presses the contact portion 19b in the 1 st direction, so that the shaft 15 moves in the 1 st direction together with the contact portion 19 b. According to the above configuration, the position of the throttle lever 6 can be finely adjusted by further reducing the amount of movement of the shaft 15 in the 1 st direction. Specifically, for example, the position of the throttle lever 6 can be adjusted on the order of micrometers (in units of several micrometers).

In the present embodiment, since the contact portion 19b is a roller that can rotate on the inclined surface 19a, the frictional resistance between the contact portion 19b and the inclined surface 19a can be reduced, and the function of the cam portion 19 can be stabilized.

Further, in the present embodiment, since the biasing portion 21 maintains a state in which the shaft 15 is biased toward either one of the moving portion 18 and the cam portion 19, even if the moving portion 18 moves in either one of the 3 rd directions, the cam portion 19 stably functions to stably move the shaft 15 in either one of the 1 st directions. That is, by moving the moving portion 18, the throttle lever 6 can be moved forward into the slot 5 and also moved backward from the slot 5. Therefore, the position adjustment of the throttle lever 6 is easily performed. Further, since the contact state between the inclined surface 19a and the contact portion 19b can be maintained satisfactorily by the biasing force of the biasing portion 21, the play (gap) of the cam portion 19 can be suppressed, and the function of the cam portion 19 can be stabilized.

In the present embodiment, a plurality of adjustment mechanisms 7 are provided side by side in the 2 nd direction.

At this time, the amount of protrusion of the throttle lever 6 into the slot 5 can be adjusted at each position in the 2 nd direction by the plurality of adjustment mechanisms 7. Therefore, the film thickness of the coating liquid applied to the object to be coated can be adjusted at each position in the 2 nd direction of the slit 5.

In the present embodiment, the moving portion 18 is disposed on the rear end side with respect to the connecting portion 1g located at the connecting portion between the front end surface 1c and the outer side surface 1b of the first head member 1.

In this case, the moving portion 18 is less likely to be an obstacle when the operator observes the application portion. Therefore, the coated portion can be more easily seen.

In the present embodiment, the adjustment mechanism 7 includes the operation unit 22, and the operation unit 22 moves the moving unit 18 in the 3 rd direction.

In this case, for example, a dial of a micrometer head or the like is used as the operation unit 22, and the operator can manually operate the operation unit 22 to appropriately move the moving unit 18 in the 3 rd direction. That is, the amount of protrusion of the throttle lever 6 into the slot 5 can be appropriately adjusted by operating the operating portion 22.

[ control section ]

Although not particularly shown, the control unit is electrically connected to the drive unit 24. The control unit is, for example, a control board. The control unit and the drive unit 24 may be electrically connected via wiring (i.e., wired) or may be electrically connected by radio.

The control section moves the moving section 18 in the 3 rd direction by the driving section 24 based on the detection result of the coating film thickness detecting means so that the film thickness of the coating liquid applied to the object to be coated is within a predetermined range.

[ coating method ]

Next, a coating method of applying a coating liquid to a coating object using the coating tool 20 of the present embodiment will be described. In the coating tool 20 of the present embodiment, a plurality of adjustment mechanisms 7 are also provided in parallel in the 2 nd direction.

In the coating method of the present embodiment, the coating film thickness detection means continuously acquires data of a plurality of positions in the 2 nd direction and data of each film thickness at the plurality of positions, collects the data of the positions and the data of the film thickness to an external server via a network, calculates a difference between the data of the film thickness and the data of the preset reference film thickness, compares the difference with a preset threshold value, and when the difference exceeds the threshold value, the drive section 24 drives the moving section 18 of the adjustment means 7 closest to the position exceeding the threshold value in the 2 nd direction in the 3 rd direction, and adjusts the amount of protrusion of the throttle lever 6 into the slot 5 so that the difference is equal to or less than the threshold value.

[ Effect of the present embodiment ]

According to the coating tool 20 of the present embodiment described above, the same operational effects as those of the above-described embodiment can be obtained.

In the present embodiment, the adjustment mechanism 7 includes the driving unit 24, and the driving unit 24 drives the moving unit 18 in the 3 rd direction.

That is, the amount of protrusion of the throttle lever 6 into the slot 5 can be appropriately adjusted by remote operation.

Further, since the coating tool 20 of the present embodiment includes the coating film thickness detection mechanism and the control unit, the film thickness of the coating liquid applied to the object to be coated is automatically limited to a predetermined range, and the coating accuracy can be stably improved.

In addition, according to the coating method using the coating tool 20 of the present embodiment, the film thickness of the coating liquid applied to the object to be coated is automatically made uniform at each position in the 2 nd direction, and the coating accuracy can be stably improved.

As shown in fig. 11, the main body portion support portion 25b is substantially C-shaped in a rear view of the application tool 30 as viewed from the rear end side. The main body support portion 25b has an insertion hole and a slit. The insertion hole penetrates the main body portion support portion 25b in the 3 rd direction. In the present embodiment, the insertion hole is a circular hole. The body 17 is inserted into the insertion hole. The distal end portion of the main body 17 is disposed inside the insertion hole. The slit opens to a side surface (in the present embodiment, the right side surface) facing the 2 nd direction of the main body portion support portion 25b and the insertion hole. Thereby, the main body portion support portion 25b can be elastically deformed to change the inner diameter of the insertion hole.

The clamp screws 25d are provided to the body support portions 25b, respectively. The clamp screw 25d extends in the 1 st direction at the upper and lower portions of the slit of the main body support portion 25 b. By tightening the clamp screw 25d, the main body portion support portion 25b is elastically deformed, and the inner diameter of the insertion hole is shortened. Thereby, the main body 17 is fixed to the main body support portion 25 b. Then, the deformation of the main body portion support portion 25b is restored by loosening the clamp screw 25d, and the inner diameter of the insertion hole is restored to the original size. This releases the state in which the body 17 is fixed to the body support portion 25 b.

[ Effect of the present embodiment ]

According to the coating tool 30 of the present embodiment described above, the same operational effects as those of the above-described embodiment can be obtained.

In the present embodiment, the main body portions 17 of the plurality of adjustment mechanisms 7 are supported by the fixing portions 25, and the plurality of adjustment mechanisms 7 and the fixing portions 25 are unitized. By fixing this unit to the 1 st head member 1, the coating tool 30 can be easily assembled.

[ fixed part ]

In the present embodiment, the fixing portion 25 includes a fixing rod 25a, a main body portion support portion 25b, a fixing screw 25c, a clamp screw 25d, a shaft support portion 25e, and a bolt member 25 f.

The shaft support portion 25e is connected to an end portion of the fixed rod 25a on the 3 rd direction leading end side. The shaft support portion 25e is fixed to the fixing rod 25a by a bolt member 25 f. In the present embodiment, the bolt member 25f extends along the 1 st direction. The shaft support portion 25e protrudes from an end surface of the fixed rod 25a toward the distal end side. The tip end of the shaft support portion 25e is located above the 2 nd recessed portion 12. That is, the tip end of the shaft support portion 25e is disposed so as to overlap the 2 nd recessed portion 12 when viewed in the 1 st direction, i.e., the vertical direction. The distal end portion of the shaft support portion 25e is formed in a U shape that opens toward the distal end side in the 3 rd direction when viewed from the 1 st direction. The shaft support portion 25e has a pair of arm portions 25g disposed at the distal end portion of the shaft support portion 25 e. The pair of arm portions 25g are arranged at intervals along the 2 nd direction. The lower surface of the portion of the shaft support portion 25e other than the distal end portion contacts the outer side surface 1b of the first head member 1.

A plurality of shaft support portions 25e are provided at intervals along the 2 nd direction. The number of the shaft supporting portions 25e is the same as the number of the shafts 15.

[ adjusting mechanism ]

In the present embodiment, the shaft 15 of the adjustment mechanism 7 does not have the roller support portion 15 c. The flange 15b is screwed to the shaft 15. Therefore, the flange portion 15b is rotated about the central axis of the shaft 15 with respect to the shaft 15, whereby the position of the flange portion 15b in the vertical direction can be adjusted with respect to the shaft 15. The portion of the shaft 15 located above the flange 15b, i.e., the upper end portion, is substantially cylindrical and extends in the 1 st direction. The upper end surface of the shaft 15 is flat and perpendicular to the 1 st direction.

In the present embodiment, the moving portion 18 of the adjustment mechanism 7 does not have the pressing block 18 b. The front end surface of the actuator shaft 18c is flat and perpendicular to the 3 rd direction.

In the present embodiment, the cam portion 19 of the adjustment mechanism 7 includes a rotation shaft 19c and a rotation member 19d instead of the inclined surface 19a and the roller (contact portion) 19 b.

The rotation shaft 19c has a shaft shape extending along the 2 nd direction. Both ends of the rotating shaft 19c are supported by a pair of arm portions 25g of the shaft support portion 25 e.

The rotating member 19d has a plate shape, and the pair of plate surfaces face the 2 nd direction. The rotating member 19d has a portion located between the pair of arm portions 25g and attached to the rotating shaft 19 c. The rotating member 19d is rotatable about the center axis C of the rotating shaft 19C.

The rotating member 19d has a 1 st contact portion 19e and a 2 nd contact portion 19 f.

The 1 st contact portion 19e constitutes a part of the outer surface of the rotating member 19 d. In the present embodiment, the 1 st contact portion 19e is disposed at the upper end portion of the rotating member 19d and faces the rear end side in the 3 rd direction. The 1 st contact portion 19e is located on the upper side than the center axis C of the rotation shaft 19C. The 1 st contact portion 19e is located on the rear end side in the 3 rd direction with respect to the center axis C. The 1 st contact portion 19e has a convex curved surface shape protruding toward the rear end side in the 3 rd direction. The 1 st contact portion 19e contacts the front end surface of the actuator shaft 18 c. That is, the 1 st contact portion 19e contacts the moving portion 18 in the 3 rd direction. The moving portion 18 moves toward the distal end side in the 3 rd direction, whereby the 1 st contact portion 19e can be pressed toward the distal end side by the moving portion 18.

The 2 nd contact portion 19f constitutes a part of the outer surface of the rotating member 19 d. In the present embodiment, the 2 nd contact portion 19f is disposed at the lower end portion of the rotating member 19d and faces downward in the 1 st direction. The 2 nd contact portion 19f is located on the 3 rd direction leading end side with respect to the center axis C of the rotating shaft 19C. The 2 nd contact portion 19f is located below the center axis C. The 2 nd contact portion 19f is formed in a convex curved surface shape protruding downward in the 1 st direction. The 2 nd contact portion 19f is in contact with the upper end surface of the shaft 15. That is, the 2 nd contact portion 19f contacts the shaft 15 in the 1 st direction. When the moving portion 18 presses the 1 st contact portion 19e toward the 3 rd direction distal end side, the rotating member 19d rotates about the center axis C of the rotating shaft 19C, and the 2 nd contact portion 19f presses the shaft 15 toward the 1 st direction lower side.

In the present embodiment, the cam portion 19 also converts the movement amount of the moving portion 18 in the 3 rd direction into the movement amount of the shaft 15 in the 1 st direction.

As shown in fig. 17, when viewed in a cross section perpendicular to the center axis C of the rotating shaft 19C, the distance between the contact point where the 1 st contact portion 19e and the moving portion 18 contact (hereinafter referred to as the 1 st contact point) and the center axis C is different from the distance between the contact point where the 2 nd contact portion 19f and the shaft 15 contact (hereinafter referred to as the 2 nd contact point) and the center axis C.

Specifically, in the present embodiment, the distance between the 2 nd contact and the central axis C is smaller than the distance between the 1 st contact and the central axis C. Therefore, the cam portion 19 converts the movement amount of the moving portion 18 in the 3 rd direction into the movement amount of the shaft 15 in the 1 st direction which is smaller than the movement amount.

In the present embodiment, the biasing portion 21 of the adjustment mechanism 7 biases the shaft 15 toward the cam portion 19 in the 1 st direction. Specifically, the biasing portion 21 biases the shaft 15 upward toward the 2 nd contact portion 19f of the cam portion 19.

[ Effect of the present embodiment ]

According to the coating tool 50 of the present embodiment described above, the same operational effects as those of the above-described embodiment can be obtained.

Specifically, when the moving portion 18 moves in the 3 rd direction and presses the 1 st contact portion 19e of the rotating member 19d, the rotating member 19d rotates about the rotating shaft 19 c. Thereby, the 2 nd contact portion 19f of the rotating member 19d pushes the shaft 15 in the 1 st direction, and the amount of protrusion of the throttle lever 6 into the slot 5 is adjusted. The cam portion 19 is provided with a simple structure, and the amount of movement of the moving portion 18 in the 3 rd direction is stably converted into the amount of movement of the shaft 15 in the 1 st direction by the cam portion 19.

In the present embodiment, by appropriately setting the distance between the 1 st contact and the center axis C and the distance between the 2 nd contact and the center axis C, the ratio of the amount of movement of the moving portion 18 in the 3 rd direction to the amount of movement of the shaft 15 in the 1 st direction corresponding to the amount of movement can be adjusted.

In the present embodiment, since the cam portion 19 is coupled to the fixing portion 25 and is unitized, the assembling property of the application tool 50 can be improved or maintenance can be efficiently performed by attaching and detaching the unit to and from the 1 st head member 1.

[ other structures encompassed by the invention ]

The present invention is not limited to the above-described embodiments, and for example, as described below, structural changes and the like can be made without departing from the scope of the present invention.

In the above embodiment, the slit 5 is opened to the outside in the horizontal direction, but the 3 rd direction in which the slit 5 is opened is not limited to the horizontal direction.

The throttle levers 6 may be fixed independently of the shafts 15 of the adjusting mechanisms 7.

In the above-described embodiments 1 to 4, the contact portion 19b of the cam portion 19 is a roller, but is not limited thereto. The contact portion 19b may be a sliding member or the like that is slidable with respect to the inclined surface 19a, for example. However, when the contact portion 19b is a roller, the frictional resistance between the inclined surface 19a and the contact portion 19b can be significantly reduced, which is more preferable.

In the above embodiment, the manifold 4 has a groove shape recessed in the 1 st direction from the inner surface 2a of the 2 nd head member 2 and extending in the 2 nd direction, but the present invention is not limited thereto. The manifold 4 may be in the form of a groove that is recessed from the inner surface 1a of the first head member 1 in the 1 st direction and extends in the 2 nd direction. At this time, the manifold 4 is recessed from the inner side surface 1a to the upper side.

The manifold 4 may further include: a 1 st groove portion recessed upward from an inner surface 1a of the 1 st head member 1 and extending in the 2 nd direction; and a 2 nd groove portion recessed downward from the inner surface 2a of the 2 nd head member 2 and extending in the 2 nd direction. The 1 st groove and the 2 nd groove are opposed to each other in the 1 st direction and communicate with each other. At this time, the manifold 4 as a whole is formed into, for example, a substantially circular shape when viewed in a cross section perpendicular to the 2 nd direction.

In the above-described embodiments 3 to 5, an example in which only one fixing portion 25 is provided is described, but the present invention is not limited to this. The fixing portions 25 may be provided in parallel in the 2 nd direction. In this case, the fixing portion 25 is prevented from becoming too long in the 2 nd direction, the fixing portion 25 is easy to handle, and the application tools 30, 40, and 50 are easy to assemble.

In the above-described embodiment 5, the example in which the shaft support portion 25e is fixed by the fixing rod 25a and the bolt member 25f is described, but the present invention is not limited to this. The shaft support portion 25e, the fixing lever 25a, and the main body portion support portion 25b may be integrally formed as a single member. In this case, since the fixing lever 25a, the plurality of body portion supporting portions 25b, and the plurality of shaft supporting portions 25e are formed as a single member, the number of components of the application tool 50 can be reduced, and the assembly can be easily performed. Further, the fixing lever 25a, the plurality of body supporting portions 25b, and the plurality of shaft supporting portions 25e are not displaced relative to each other, and the coating accuracy can be maintained well. Further, the fixing lever 25a, the plurality of body supporting portions 25b, and the plurality of shaft supporting portions 25e do not need to be aligned, and workability at the time of assembly, maintenance, and the like is improved.

In addition, the respective configurations (constituent elements) described in the above embodiments, modifications, descriptions, and the like may be combined and additions, omissions, substitutions, and other modifications of the configurations may be made without departing from the spirit of the present invention. The present invention is not limited to the above-described embodiments, but is defined only by the claims.
