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]

As in the example of this prior art, a large number of the clamping tools are attached to a chain conveyor, etc., and a flexible membrane with insertion holes provided at appropriate intervals is also stretched on the front surface of the paint tank. If a large number of thin rod-like bodies are painted at once, it is suitable for so-called undercoating work in which a large number of thin rod-like bodies are painted with the same type of paint. On the other hand, according to the 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 fixed in position. The thin rod cannot be moved while the paint tank is moving back and forth.

In other words, the feeding and discharging process is time-consuming, as it requires intermittent drive to feed untreated thin rods into the coating position while moving the coated thin rods away from the coating position. If the number of thin rods to be processed is small, the efficiency of the painting operation will be extremely poor.

Therefore, if the above-mentioned prior art is applied to a painting operation in which a small number of thin sticks are coated with many different types of coatings, such as the surface finishing coating of chopsticks, the efficiency of the painting operation will deteriorate, and the above-mentioned problem will occur. If such a supply/discharge device is made into a large-scale mechanism such as a chain conveyor, there is a problem in that the cost of the entire device increases and the device becomes larger.

Furthermore, in the prior art, when the paint tank is moved back after the paint in the paint tank has been applied to the vicinity of the base of the thin rod-like body, a flexible membrane made of rubber or the like is stretched around the outer circumference of the thin rod-like body. Since it has the action of handling the surface, there is a clamping tool that firmly and firmly holds the root of the thin rod-like object against the force of this handling action, and a clamping tool that bites into the vicinity of the root to prevent it from falling out. There is also the problem that a device such as a knife-shaped support is required, making the entire coating device even larger and more complicated.

The present invention solves the above two problems at once,
The purpose is to provide a compact coating device.

[Means to solve the problem]

In order to achieve this objective, the invention as set forth in claim 1 provides a flexible material with an insertion hole on the front surface of a paint tank containing paint such as lacquer, into which a thin rod-like body such as a chopstick material can be inserted from its tip. A membrane is stretched over the membrane, and the thin rod-shaped body is configured to be pushed toward the insertion hole of the flexible membrane by a supply means disposed on the front side of the paint tank, while being pushed into the paint tank. A support body facing into the paint tank so as to be in contact with the tip of the thin rod-like body is provided so as to be movable back and forth along the longitudinal axis of the thin rod-like body, and the paint tank is placed inside the paint tank. With the thin rod-like body being pushed in, the thin rod-like body is horizontally reversed so as to approach the ejection means that pinches and pulls out the base of the thin rod-like body, and after the reversal movement, the ejecting means is removed from the paint tank. The supporting body is configured to push the tip of the thin rod-like body in the paint tank back toward the flexible membrane in synchronization with the movement away from the paint tank.

The invention described in claim 2 is characterized in that the thin rod-shaped body coating apparatus according to claim 1 includes: a pressing part of the thin rod-shaped body by the supply means; a root part holding part of the thin rod-shaped body by the discharge means; The contact portion of the tip of the thin rod-like body of the support body is arranged in a straight line in a plan view, and the supply means, the interlocking mechanism of the support body, and the discharge means are mounted on a single operating shaft. The operating shaft is configured to be driven back and forth.

[Operation and effect of the invention]

According to the structure of the invention described in the first claim, there is provided a means for supplying the thin rod-like body toward a paint tank having a flexible membrane with an insertion hole stretched on the front surface, and a means for supplying the thin rod-like body after painting into the paint tank. The paint tank is placed in a separate location from the discharge means to be pulled out from the paint tank, and the paint tank is reversely moved to approach the discharge means side while the thin rod-shaped body is pushed into the paint tank. Therefore, after the thin rod-like object is pushed into the paint tank, at the supply means, a preparatory process is carried out in which the next untreated thin rod-like object is supplied to the supply means while the paint tank is rotating in reverse. On the other hand, even at the discharge means, while the supply means is pushing the thin rod into the paint tank, the thin rod can be moved to a predetermined location after painting is finished, etc. Since the preparatory work for supplying and discharging the thin rod-shaped bodies before and after the work can be carried out substantially in parallel, it has the effect of increasing the efficiency of the painting work even in the case of small-volume production of a wide variety of products.

The supply means may have the function of simply pushing the substantially horizontal thin rod-like body toward the flexible membrane of the paint tank by pushing its base portion toward the flexible membrane of the paint tank.

On the other hand, in the process of discharging the thin rod-shaped body, the tip is pushed into the paint tank at the flexible membrane of the paint tank, and the protruding root part is held by the discharge means so that the thin rod-shaped body leaves the paint tank. When the discharging means is driven, the tip of the thin rod-like body pushed into the paint tank is pushed back by the support body facing inside the paint tank, so that the outer periphery of the thin rod-like body is The root portion of the thin rod-like body will not be pulled out and fall off from the ejection means due to handling of the surface, and the force required to clamp the root portion by the ejection means may be light.

Therefore, the structures of the supply means and the discharge means are extremely simple, and the structure of the coating apparatus can be simplified and made compact.

Further, according to the second aspect of the invention, the supply means is disposed on one side of the paint tank and the discharge means is disposed on the other side, and the supply means presses the base of the thin rod-like body. The abutting part of the tip of the thin rod-like body on the support in the paint tank and the gripping part of the base by the discharge means are arranged in a straight line in a plan view, and the back and forth movement of the supply means and the support is controlled. The interlocking mechanism for the discharge and the ejection means are attached to one operating shaft, and the operating shaft is moved back and forth, so even if the three are located at different locations, they can be moved by one driving means. This has the effect that it is possible to carry out the work of supplying and discharging thin rod-shaped bodies, and that the number of parts is reduced, contributing to the simplification of the structure of the coating apparatus.

Note that the notch portion 29 is formed so that the tips of the pair of upper and lower gripping claws 26a, 26a do not come closer than a predetermined value.

The longitudinal support 10, which has a substantially rectangular cross section, has holes 30 formed at a certain pitch on one side thereof into which the bases of the thin rod-like bodies A can be inserted. It is fed in the longitudinal direction at the constant pitch.

When the supply means 8 and the discharge means 9 are installed so as to move back and forth integrally with the actuation shaft 11 which moves back and forth by the actuator 13 such as the air cylinder, the distances of movement of both means are equal. Should be set.

That is, the thin rod-like object A is pushed into the paint tank 4 by pushing the root part of the thin rod-like object A with the supply means 8.
is stopped with the root portion protruding from the flexible membrane 6 of the paint tank 4 by an appropriate dimension;
Before horizontally inverting the paint tank 4, move distance L1 to move backward away from the paint tank 4, and after the paint tank 4 inverts, the root part of the thin rod-shaped body A is The length L1 of the forward and backward movement of the thin rod-like body A when it is held and pulled out from the paint tank 4 so that the root of the thin rod-like body A fits into the hole 30 of the support 10 should be set equal to When the supply means 8 and the discharge means 9 are operated by separate actuators to approach and move away from the paint tank 4, 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 moving 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 the supporting body 33. 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 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.

In addition, so that the support body 33 can be moved back and forth only within the paint tank 4, the distance L2 of the support body 33 can be changed back and forth between the supply means 8 and the discharge means 9, which move back and forth integrally with the operating shaft 11. Travel distance L1
It is set short.

Then, the actuator 40 is driven so as not to drive the support body 33 while the support body 33 has moved to the rear side of the paint tank 4, and the engagement pin 39 of the movable body 31 and the gripping arm 36 are engaged with each other. After the paint tank 4 is released, the paint tank 4 is configured to be reversed so that its front surface (the side on which the flexible membrane 6 is provided) is directed toward the discharge means 9 side, and the paint tank 4 is configured to be reversely moved so that the front surface (the side on which the flexible membrane 6 is provided) is directed toward the discharge means 9 side. After the discharging means 9 is brought close and the root portion of the thin rod-like body A is clamped, the support body 33 is pushed back toward the flexible membrane 6 in synchronization with the discharging means 9 moving away from the paint tank 4. It is composed of:

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, while the support body 33 in the paint tank 4 does not retreat too much. As shown in FIG. The tip of the holder is supported so that it cannot fall (see Figure 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 not necessary to set the moving direction of the support in the paint tank 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 apparatus, the degree of freedom in layout of the coating apparatus is increased.
