The present invention relates to an improvement in an automatic varnish wiping device suitable for removing impurities.

[Conventional technology]

Conventionally, this technology removes dust adhering to the surface of a flat plate by bringing a dust removal roller made of a roll of urethane elastomer, which has self-adhesive polymer properties and elasticity, into contact with the flat plate during the transport process of the plate. It was hot.

And, such technology, for example,
-Disclosed in Publication No. 242659.

However, conventionally, when removing impurities adhering to the surface of an automobile, a worker manually wipes the varnish along the surface of the automobile body.

At the very least, no technology has been found to date that allows a car to reliably wipe varnish on a curved surface such as the surface of a car body.

[The problem that the idea aims to solve]

However, the conventional method involves wiping by hand, so when wiping the side surfaces of automobile fenders, doors, quarters, etc., it is necessary to take a bent position, which poses problems such as lower back pain for the worker. It was hot.

In addition, despite the need to reduce product costs, there is the problem of not being able to reduce the amount of varnish gauze used, and the problem of varnish gauze being replaced frequently because it is usually used in a palm-sized shape folded in four. It was hot.

Therefore, an object of the present invention is to automatically and reliably wipe the varnish of a painting body.

[Means to solve the problem]

Therefore, the present invention includes a machine body 2 that is slidably mounted on a base 22 and can move forward and backward with respect to the painting body 17, and a machine body 2 that protrudes from the machine body 2 toward the painting body 17. 1
A wiping head 4 is attached to the machine body 2 at a position opposite to the wiping head 7, and one end is connected to the machine body 2, and further extends to the wiping head 4 side, returns from the front surface of the base 22, and passes below the base 22. A weight mechanism 6 that has a wire 66 whose other end is stretched over a support frame 65 attached to the rear of the base 22 and a weight 62 suspended from the other end of the wire 66, and which moves the machine body 2 forward.
A cylinder body 31 is fixed to the base 22, a cylinder 3 is connected to the machine body 2 by a rod 32, a main shaft 8 is attached to both sides of the machine body 2 with the wiping head 4 sandwiched therebetween, and The winding shaft 9 is connected to the winding shaft 9 from the main shaft 8 via the wiping head 4.

[Effect]

When the body to be painted is transported to the varnish wiping process by the above-mentioned means, the operation of the cylinder that maintains the machine body in the retracted position is stopped,
Set the rod in a free state. As a result, the machine body moves toward the body side via the wire due to the load of the weight, the wiping head attached to the machine body is pressed against the body, and as the body moves due to transportation, the roll varnish on the wiping head is transferred to the body. Wipe the surface.

When the varnish has been wiped off, the cylinder is actuated with a force greater than the load of the weight, and the rod is moved in the direction of contraction. This causes the machine body and the wiping head to move backward, and the wiping head to separate from the body. Further, as the machine body moves backward, the ratchet gear engages with the hook gear and rotates. Along with this, the winding shaft rotates via the chain, the roll varnish is fed by a predetermined width, and the roll varnish is ready for the next wiping.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 is a perspective view showing a schematic configuration of an automatic varnish wiping device according to the present invention, and FIG. 2 is a plan view thereof.

The automatic varnish wiping device 1 detects when a painting body 17 of an automobile is transported to a varnish wiping process, and varnishes it from both the left and right sides.

Further, in order to cope with the unevenness of the painting body 17, the automatic varnish wiping device 1 adopts a contact surface division method, and three devices are provided on each of the left and right sides of the painting body 17.

The automatic varnish wiping device 1 includes a machine body 2, a wiping head 4, a weight mechanism 6,
It is composed of a cylinder 3, a main shaft 8, a winding shaft 9, a roll varnish 11, a ratchet gear mechanism 13, and a chain 15.

The machine body 2 has a slider 5 on the base 22.
It is slidably attached to the painting body 17 and can move forward and backward with respect to the painting body 17.

The wiping head 4 slightly protrudes from the machine body 2 toward the body 17 and has a support member 7 extending from the machine body at a position facing the painting body 17.
is attached to.

The wiping head 4 is connected to the painting body 1.
It is made of cushion rubber so that it can cope with the unevenness of 7.

The weight mechanism 6 is a mechanism that moves the machine body 2 forward (moves it toward the body 17 side), and the weight mechanism 6 is a mechanism that moves the machine body 2 forward (moves toward the body 17 side).
and a weight 62. in particular,
One end of the wire 66 is connected to a mounting plate 64 attached to the bottom of the machine main body 2, further extends to the wiping head 4 side, and is returned by a pulley 63 attached to the support member 7 to connect the base 22 from the front surface of the base 22. The other end is stretched over a pulley 61 of a support frame 65 attached to the rear of the base 22. Furthermore, a weight 62 is suspended from the other end of this wire 66.

Then, due to the load of the weight 62, the machine body 2
moves on the base 22 to the body 17 side, and moves the wiping head 4 connected to the machine body 2 to the body 1.
It will be pressed to the 7 side.

Note that three types of weights 62, large, medium, and small, are prepared, and the pressing force against the body 17 of the wiping head 4 can be adjusted.

The cylinder 3 moves the machine body 2 backward (body 1
7 side),
The cylinder body 31 is fixed to the base 22,
A rod 32 is connected to the bottom of the machine body 2.

Then, by operating the rod 32 in the direction of contraction with a force greater than the load of the weight 62, the machine body 2 is moved backward.

The main shaft 8 and the winding shaft 9 are both made of vinyl chloride pipes, and are attached to both sides of the machine body 2 with the wiping head 4 in between.

Roll varnish 11 is used as the varnish,
It is a one-way operation system in which varnish is wound on one side and wound on the other side, and is applied from a main shaft 8 via a wiping head 4 to a winding shaft 9.

However, at the end of the winding, the main shaft 8
By replacing the winding shaft 9, the back side of the roll varnish 11 can also be used, thereby reducing the cost.

The ratchet gear mechanism 13 is attached to the machine body 2 and rotates in conjunction with the backward movement of the machine body 2.

That is, when the machine main body 2 is retreating, the machine main body 2
A ratchet gear 132 that retreats together with the machine body 2 engages with a hook gear 134 attached to the base 22, and as the machine body 2 moves backward, the ratchet gear 132 engages with the hook gear 134 and rotates. As the ratchet gear 132 rotates, the ratchet gear 13
The winding shaft 9 is rotated via a chain 15 wound between the roll varnish 2 and the winding shaft 9, and the roll varnish 11 is fed by a predetermined width.

Note that 133 is a hook for preventing the ratchet gear 132 from reversing.

Further, in order to prevent the roll varnish 11 from shifting or sagging, a guide bar 24 is attached to the machine body 2, and tension is constantly applied to the roll varnish 11 in the outward direction.

To explain the operation of the embodiment according to the above configuration, when the painting body 17 is transported to the varnish wiping process, the operation of the cylinder 3 that maintains the machine body 2 in the backward position is stopped, and the rod 32 is in a free state. As a result, the machine body 2 moves toward the body 17 via the wire 66 due to the load of the weight 62, and the wiping head 4 attached to the machine body 2 is pressed against the body 17, and as the body 17 moves due to conveyance. The roll varnish 11 on the wiping head 4 is the body 17
wipe the surface.

When the varnish wiping is completed, the cylinder 3 is actuated with a force greater than the load of the weight 62, and the rod 32 is moved in the direction of contraction. As a result, the machine body 2 and the wiping head 4 move backward, and the wiping head 4 separates from the body 17.
Further, as the machine main body 2 moves backward, the ratchet gear 132 engages with the hook gear 134 and rotates. Along with this, the winding shaft 9 rotates via the chain 15, the roll varnish 11 is fed by a predetermined width, and the roll varnish 11 is in a waiting state for the next wiping.

In this way, the forward and backward movement of the machine body 2 having the wiping head 4 is controlled by the weight mechanism 6 and the cylinder 3.
Since this can be done automatically, varnish wiping of the painting body 17 can be automated.

This eliminates the need for the worker to bend over and improves work efficiency.

Further, when wiping off the varnish, an appropriate pressing force is always applied to the body 17 by the wiping head 4 via the weight mechanism 6, so that the body 17
varnish can be wiped off reliably.

Although specific embodiments of the present invention have been described above, the present invention is not limited thereto, and various other embodiments can be considered by those skilled in the art within the scope of the claims for utility model registration.

For example, in the above embodiment, the main shaft and the winding shaft are made of vinyl chloride pipes, but they may be made of metal pipes instead of vinyl chloride pipes.

[Effect of idea]

As explained above, in the present invention, the machine body having the wiping head can be automatically moved forward and backward using the weight mechanism and the cylinder, so that varnish wiping of the painting body can be automated. This eliminates the need for the worker to bend over and improves work efficiency.

Also, when wiping off the varnish,
Since an appropriate pressing force is always applied by the wiping head via the weight mechanism, the varnish can be reliably wiped off from the body.
