Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for painting the outer peripheral surface of a thin rod-shaped object such as chopsticks with paint such as lacquer.

[Conventional technology]

A device for applying lacquer or other paint to the outer circumferential surface of bamboo or wooden chopsticks, etc., which have a narrow tip and become thicker toward the base.
Publication No. 58791 discloses that, in front of a plurality of clamping tools that clamp the root portion of a thin rod-like body in a substantially horizontal state from above and below, a flexible insertion hole is provided on the front surface through which each thin rod-like body can be inserted from its tip. A paint tank with a membrane stretched thereon is provided so as to be movable back and forth, and a knife-like support is provided near the front end of each clamping tool so as to be movable up and down. A configuration is disclosed in which the root portion of the thin rod-like body is pushed up and brought into contact with each other, and the root portion of the thin rod-like body is held between the knife-like support and the holding tool in a self-centering manner so as to be swingable.

[Problem to be solved by the invention]

According to this prior art, the paint tank is moved back and forth toward the tip of the thin rod-like body held by a clamping tool that is held in a fixed position. When the paint tank retreats, the elastic flexible membrane made of rubber or other material stretched over the front of the paint tank has the effect of handling the outer peripheral surface of the thin rod-shaped body, so it resists the force of this handling action. This requires equipment such as a clamping tool to tightly and firmly hold the base of the thin rod-like body and a knife-shaped support to bite into the vicinity of the base to prevent it from coming off, making the coating equipment large and complicated. There was a problem of becoming

Such a problem also occurs when the thin rod-like body is pulled out even when the thin rod-like body is pushed from the tip toward the front flexible membrane of a fixed-position paint tank.

The object of the present invention is to solve this problem and provide a compact coating device.

[Means to solve the problem]

In order to achieve this purpose, the present invention has an insertion hole on the front surface of the paint tank containing paint such as lacquer, into which a thin rod-like object such as chopstick material placed approximately horizontally can be inserted from its tip. A flexible membrane is stretched, and one or both of the thin rod-like body or the paint tank is moved toward and away from the other party, and the thin rod-like body is passed through the insertion hole of the flexible membrane. While the support is configured to be pushed into the paint tank, the support faces the paint tank and is configured to push back the tip of the thin rod-like body in the paint tank toward the flexible membrane. Alternatively, it is configured to drive one or both of the paint tanks.

[Operation and effect of the invention]

According to this configuration, a thin rod-like body is pushed toward a paint tank having a flexible membrane with an insertion hole stretched on the front surface, and then pulled out. While holding the base of the thin rod-like body to hold it, a paint tank with a flexible membrane similar to that described above stretched on the front was brought close, and the thin rod-like body was pushed into the paint tank from the tip. After that, the paint tank is moved backward and the thin rod-like body is pulled out, and the means for holding the thin rod-like body at its base and the paint tank are brought close together and pushed together, and then the two are separated. be.

In any of these cases, when pulling out the thin rod-like body that has been pushed in with its root portion left outside from the insertion hole in the flexible membrane of the paint tank, the outer periphery of the thin rod-like body must be Since a handling action occurs, a force that causes the root portion to fall off is likely to act at the location where the thin rod-shaped body is held between the root portions.

Therefore, in the present invention, in the step of discharging the thin rod-like body, either or both of the support body supporting the tip of the thin rod-like body facing into the paint tank and the paint tank are driven. In other words, one or both of the support and the paint tank,
The flexible membrane and the support in the collapsed paint tank are driven to move closer to each other.

As a result, the tip of the thin rod-like body pushed into the paint tank is pushed back by the support facing inside the paint tank, so the force applied to the outer peripheral surface of the thin rod-like body by the flexible membrane is exerted. This makes it extremely easy to push the thin rod-like object out of the paint tank, and the root portion of the thin rod-like object will not be pulled out and fall off from the clamping means, and the root portion will not be held by the clamping means. Only a light force is required.

Therefore, it has the excellent effect that the structure of the means for holding the root portion of the thin rod-shaped body and, by extension, the structure of the coating device can be simplified.

The longitudinal movement distance (L1) that the thin rod-like body A moves so that the root part of the thin rod-like body A fits into the hole 30 of the support 10 after being pulled out from the paint tank 4 while holding the thin rod-like body A is set equal to However, the supply means 8 and the discharge means 9 should be connected to the paint tank 4 by separate actuators.
When operating the vehicle to approach or move away from the target, the moving distances of the two means may be set to be different.

Reference numeral 31 denotes a gate-shaped frame-shaped movable body that is movable along the longitudinal direction of the paint tank 4, and the lower ends of the movable body 31 on both left and right sides are guide rails arranged parallel to the lower left and right sides of the paint tank 4. 32, 32
It is slidably fitted into the.

A support 33 is provided on the upper piece 31a of the moving body 31.
The support body 33 has a thin rod-like shape inserted through the insertion hole 7 of the front flexible membrane 6 of the paint tank 4 on one side of the support body 33 near the lower end. A support portion 33a (projecting like a shelf at the lower end) is configured to support the tip of the body A so that it does not fall. In this case, it is preferable to form a recessed part 34 in the support part 33a, into which the tip of the thin rod-like body A can be fitted and held in place so as not to be displaced.

Reference numeral 35 denotes an interlocking mechanism for moving the gate-shaped frame-shaped movable body 31 and the supporting body 33 back and forth along the longitudinal direction of the paint tank 4. A gripping arm 36 in the interlocking mechanism 35 is attached to the operating shaft 11 in the axial direction and A bifurcated gripping portion 38 at the tip of the gripping arm 36, which protrudes from a boss portion 37 that is slidably fitted around the axis, rotates upward from the upper piece 31a of the movable body 31 when the gripping arm 36 rotates downward. The gripping arm 36 can be engaged with the protruding engagement pin 39.
It is configured so that it comes off from the engagement pin 39 when it rotates upward.

Reference numeral 40 denotes a drive actuator that moves the gripping arm 36 up and down, and in the embodiment, it is composed of an air cylinder.

The stopper body 48 is a stopper body that prevents the support body 33 from moving beyond a predetermined distance (L2) when it moves away from the flexible membrane 6, and the stopper body 48 protrudes from an immovable part such as the support base 2 or the guide rod 14. The stopper body 48 is brought into contact with a location that can move integrally with the movement of the support body 33 such as the gripping arm 36, the support bracket 41, and the movable body 31.

Note that the boss portion 37 and both fixed collars 45, 4
A biasing spring is installed between both the support body 33 and the paint tank 4 to bias the boss portion 37 in either direction along the operating axis 11 in a balanced manner. Stopper bodies may be provided on both sides so that only the movement can be made.

In addition, the supply means 8 and the discharge means 9 move back and forth integrally with the operating shaft 11 so that the support 33 is moved back and forth only within the paint tank 4, so that the back and forth movement distance (L2) of the support 33 is adjusted. It is natural to set it short compared to the forward and backward movement distance (L1) of .

Then, the actuator 40 is driven so as not to drive the support body 33 when the support body 33 has moved to the rear side of the paint tank 4, and the movable body 3
After releasing the engagement between the engagement pin 39 of No. 1 and the gripping arm 36, the paint tank 4 is removed from its front surface (the flexible membrane 6
The side with which the thin rod-shaped body A was provided was configured to move in reverse so that the side with which the thin rod-shaped body A was provided was moved in a reverse direction toward the side of the discharge means 9, and the base portion of the thin rod-like body A was held close to the paint tank 4 that was moved in reverse. Thereafter, as the discharge means 9 moves away from the paint tank 4, the support body 33 is pushed back toward the flexible membrane 6 in synchronization with the movement.

Therefore, in order to engage the gripping arm 36 with the engagement pin 39 on the movable body 31 located on the rear side of the paint tank 4 that has been reversely moved, the actuator 40
operate.

Reference numerals 49, 50, and 51 denote actuators 1 for moving the supply means 8 and the discharge means 9 back and forth.
This is a sensor such as a limit switch for automatically executing the timing of operation 3 and the timing of horizontal reversal of the paint tank 4.

Next, the operation and other effects of the device with this configuration will be explained.

First, as shown in FIG. 1, the thin rod-shaped body A is placed on a pair of belt conveyors 22 with its tip end facing the paint tank 4, and the guide body 2
Convey in the 0 direction.

Next, the thin rod-shaped body A is placed across the guide body 20 and the centering body 21, and the thin rod-shaped body A is pressed by the pressing part 19 at the tip of the actuator 17 in the supply means 8 which is far away from the front surface of the paint tank 4. The actuator 13 is turned on so as to push the end face of the base of the body A forward (arrow B).

With the tip of the thin rod-shaped body A entering the insertion hole 7 in the flexible membrane 6 on the front surface of the paint tank 4 to some extent, only the guide body 20 is lowered, and with the supply means 8 brought closer to the paint tank 4, the centering body is moved. 21 is lowered.

At this time, the operating shaft 1 moves in the direction of the arrow B.
1 is also equipped with an interlocking mechanism 35 and a discharge means 9 in addition to the supply means 8, and the gripping arm 36 is moved by the operation of the drive actuator 40 in the interlocking mechanism 35.
is in the lowered state, the bifurcated gripping portion 38 of the gripping arm 36 engages the engagement pin 3 of the movable body 31.
9, the movable body 31 also moves to the rear side of the paint tank 4 in conjunction with the movement of the interlocking mechanism 35, so the support body 33 attached to the movable body 31 also moves away from the flexible membrane 6. Moving.

That is, the supply means 8, the discharge means 9, and the support body 33 move integrally at the same speed and the same distance.

In addition, as the support body 33 moves away from the flexible membrane 6, the tip of the thin rod-like body A touches the support body 3.
Although the thin rod-like body A is not in contact with the support portion 33a of No. 3, it is supported by the centering body 21 and the flexible membrane 6 and can maintain a substantially horizontal state.

When most of the thin rod-like body A is inserted into the flexible membrane 6 of the paint tank 4, leaving only the root part, the centering body 21 descends, but the support body 33 in the paint tank 4 does not move back too much. As shown in FIG. The tip of the holder is supported so that it cannot fall (see Fig. 8).

When the sliding portion 18 or the like of the supply means 8 that moves toward the paint tank 4 comes into contact with one of the sensors 50, the approach movement of the supply means 8 is stopped, and at the same time, the drive actuator 40 is actuated to move the gripping arm 3
6 is rotated upward to release the engagement with the movable body 31 and stop the movement of the support body 33. On the other hand, the operating shaft 11 is rotated so that the supply means 8 moves away from the paint tank 4 by slightly delaying the timing. The actuation actuator 13 is actuated to move it in the direction of arrow C.

With this movement, the discharge means 9 is moved from the paint tank 4.
move closer to. During such operation, when the sliding part 18 etc. comes into contact with the sensor 51 in the middle, the drive motor 5 is turned on and the paint tank 4 is rotated 180 degrees (horizontal inversion) in plan view (the first (See arrow D in the figure).

In this way, when the paint tank 4 is horizontally reversed so that its front surface (the side on which the flexible membrane 6 is provided) faces the discharge means 9 side, the position of the support body 33 in the paint tank 4 is also rotated by 180 degrees in plan view. move.

Either bring the discharge means 9 closer to the paint tank 4 that has been reversely moved, or horizontally rotate the paint tank 4 to face the discharge means 9 that is stopped at the approaching position. The root portion of the thin rod-like body A protruding from the front surface is held by the holding tool 26 of the ejection means 9.

At approximately the same time as this operation, the interlocking mechanism 35 has already been moved in the direction of arrow C to correspond to the position of the movable body 31 located on the rear side of the paint tank 4, so the drive actuator 40 is turned on and the gripping arm 36 is rotated downward to engage the bifurcated gripping portion 38 and the engagement pin 39 in the gripping arm.

After the base of the thin rod-like body A is clamped by the ejection means 9 in this way, the actuator 13 is turned on.
When the operating shaft 11 is moved in the direction of arrow B, the support 33 is directed toward the flexible membrane 6 in synchronism with the movement of the discharge means 9 away from the paint tank 4 from the solid line state to the dot-dashed line state in FIG. It once pushed back and moved.

With this pushing back movement, the thin rod-like body A is pushed in the direction of the root part by the support body 33 along its longitudinal axis, so when the root side of the thin rod-like body A is handled by the insertion hole 7 of the flexible membrane 6. It is possible to overcome the resistance force, and the thin rod-shaped body A can be removed only by the gripping tool 26 of the ejection means.
When pulling out from the flexible membrane 6, the clamping tool 26
There is also no problem of the root part slipping through.

Note that as the support body 33 approaches the flexible membrane 6 in the paint tank 4, the cross-sectional area of the thin rod-like body A passing through the seven insertion holes of the flexible membrane 6 also becomes smaller.
It also has less resistance to handling.

Then, at a point where the support body 33 approaches the flexible membrane 6 to a certain distance, the interlocking mechanism 3 is stopped by the stopper body 48.
5 from approaching further, the ejection means 9 approaches the support 10, and the root of the thin rod-like body A fits into the hole 30 of the support 10, completing the ejection operation (No. 9 (See the dash-dotted line in the figure).

The thin rod-shaped body is produced by sequentially repeating such back and forth reciprocating movement of the operating shaft 11, horizontal reversing movement of the paint tank 4, and engagement/disengagement between the interlocking mechanism 35 and the movable body 33 in an appropriate order. The painting operations A can be performed one after another.

Note that one drive means may be provided so that the supply means 8 and the discharge means 9 move toward and away from the paint tank 4 in conjunction with each other, and only a drive means for moving the support body 33 along the paint tank 4 may be provided separately. ,
The driving means for moving the supplying means 8 and the discharging means 9 towards and away from the paint tank 4 are constructed separately, and furthermore, for the movement of the support 33 and the movable body 31 that move back and forth within the paint tank 4. The driving means may also be configured to be provided at the upper or lower part of the paint tank so that it can horizontally rotate integrally with the paint tank 4, and if the three driving means are configured separately in this way, , the moving distance of each means can be set and controlled freely.

Furthermore, if the three driving means are configured separately, it is necessary to set the moving direction of the support in the paint tank 4 and the reciprocating direction of the supplying means 8 and the discharging means 9 to be in a straight line. Instead, the paint tank 4 is configured to be horizontally rotated by an appropriate angle such as 90 degrees in plan view, and the supply means 8 is provided on one side so as to face the flexible membrane 6 on the front surface of the paint tank 4, and the supply means 8 is provided on the other side. Since the discharge means 9 can be disposed in the coating device, the degree of freedom in layout of the coating device is increased.

As shown in FIGS. 12 and 13, it is disposed between the front surface of the paint tank 67 and the clamping tool 64, and its upper end surface has a serrated shape that supports each tip of the thin rod-like body A. A notch groove 75 is formed,
The centering body 74 is attached to a lifting platform 76, and when the paint tank 67 moves back and forth, an actuator 77 such as an air cylinder or a drive motor is used to sink the tip of the centering body 74 below the base 61 to avoid collision. Driven up and down.

Reference numerals 78 denote supports that respectively support the tips of the thin rod-like bodies A pushed into the paint tank 67. Each support 78 is suspended from a frame 80, which will be described later, and the paint tank 6 is
The thin rod-shaped body A is inserted through the insertion hole 69 of the front flexible membrane 66 of the paint tank 67 on one side of the support body 78 near the lower end. A support portion 78a (which may protrude like a shelf from the lower end) is configured to support the tip portion so that it does not fall. In this case, it is preferable to form a recessed part 79 in the support part 78a so that the tip of the thin rod-like body A can be fitted into it and held in position so as not to be displaced.

Reference numeral 80 denotes a frame that suspends each of the supports 78 at a predetermined pitch (P), and the boss portion 8 of the frame 80
1 and 81 are slidably mounted on guide rails 82 and 82, such as a pair of round bars, arranged above the paint tank 67 and parallel to the moving direction of the paint tank 67.

Note that this guide rail 82 has one end connected to the vertical panel 62 and the other end connected to the gate-shaped frame 88 of the base 61.
It is stuck to.

Reference numerals 83 and 84 refer to fixed collars that are fixedly attached to the guide rails 82 using pins 85, respectively, and reference numerals 86 and 87 refer to fixed collars that are fitted onto the respective guide rails 82 and installed between the fixed collars 83 and 84 and the boss portion 81. The biasing springs shown in FIG.

Further, reference numerals 89 and 90 indicate stopper bodies projecting upward from the front and rear ends of the paint tank 67, and when the paint tank 67 moves back and forth by a distance (L3), the support body 78 stops at the front or rear side of the paint tank 67. In order to prevent collision between the two stopper bodies 8,
Reference numerals 9 and 90 push the front or rear surface of the frame 80 to regulate its position.

In this configuration, the tip end portion of the thin rod-like body A whose base portion is held between the clamping tools 64 is supported by the centering body 74 in the raised position, and the tip of the thin rod-like body A is placed on the front side of the paint tank 67. It is set so as to face the insertion hole 69 in the flexible membrane 66.

Next, turn on the air cylinder 68 and move the paint tank 67 containing paint such as lacquer to the thin rod-shaped body A.
move forward towards. With the tip of the thin rod-like body A fitted into the insertion hole 69 of the flexible membrane 66, the centering body 74
is lowered, and the paint tank 67 is further advanced.

At this time, the supports 78, which were regulated by the front stopper body 89 so as not to collide with the front surface of the paint tank, move forward along the guide rail 82 and fit into the recesses 79 of the support portions of the respective supports 78. The tip of the thin rod-like body A fits and supports it.

After the paint tank 67 moves forward to the vicinity of the base of the thin rod-like body A held by the clamping tool 64, the air cylinder 68 is operated in reverse to move the paint tank 67 backward.

In this state, the outer peripheral surface of the thin rod-shaped body A is painted with lacquer or the like. When the paint tank 67 retreats, the thin rod-like body A is handled by the insertion hole 69 of the flexible membrane 66, and the force of the handling acts in the direction of pulling the thin rod-like body A out of the clamping tool 64. As shown by the two-dot chain line, the tip of the thin rod-like body A is connected to the paint tank 67.
The thin rod-like body A is supported by a support member 78 inside the body so as to prevent it from coming off, and is pressed toward the base of the thin rod-like body A by the force of a biasing spring 87.

Therefore, when the thin rod-like body A is pulled out to the outside when the paint tank 67 is retreated, the thin rod-like body A can be held so as not to fall off from the clamping tool 64.

In this embodiment, the frame body suspending the plurality of supports 78 is actively moved back and forth by a drive actuator such as another air cylinder, and the frame body is moved back and forth in conjunction with the back and forth movement of the paint tank 67. The tip of the thin rod-like body A may be supported only during an appropriate range of movement.
