Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller type coating jig capable of simultaneously coating both the front and back sides of the peripheral edge of a cut plate material such as a steel plate.

[0002]

2. Description of the Related Art Among steel plates used for construction of gas tanks and the like, members such as bottom plates and side plates of tanks are coated with a groove rust preventive agent on the front and back of their peripheral portions and welded during construction. I am able to handle work.

Special coating jigs are used for coating such steel sheets, but most of them rotate with a handle held by an operator and a posture substantially orthogonal to the axis of the handle. It is provided with a roller freely attached. Then, using this roller as a felt or the like, the coating material is impregnated,
The coating material can be applied by rotating the roller along the coating surface.

In addition to such a coating jig, for example, as disclosed in Japanese Utility Model Laid-Open No. 62-109781, the handle is attached to the tip of the handle so that the rotation axes of the two rollers are orthogonal to each other, and coating is performed. There are also products that allow painting on both sides of the corners of the product that intersect at right angles.

[0005]

However, the one described in this publication can only coat two surfaces of orthogonal corners at the same time, and cannot be used as a coating jig for coating the front and back of a steel sheet.

Further, in the case of having one roller, it is necessary to first coat the front surface of the steel sheet and then coat the back surface. For this reason, after the front side is coated, the work for reversing the steel plate so that the back side can be coated is also added, and when the weight of the steel plate is large, the burden on the operator is large. Furthermore, since the front and back are painted separately,
It requires a considerable amount of skill to make the width of the coating uniform from the edge of the steel plate toward the central portion, and the coating time will also increase.

As described above, the conventional coating jig has a problem in that the front and back surfaces of the steel sheet cannot be coated at the same time, so that the work is troublesome and the coated surface becomes unbalanced.

An object to be solved in the present invention is to provide a roller type coating jig capable of easily coating both front and back surfaces of an edge portion of a plate material with the same coating width.

[0009]

According to the present invention, a frame integrally provided with two arms arranged at parallel intervals and a handle arranged in a direction extending parallel to the opposite direction of the arms, A coating roller that is rotatably arranged around the arm and has an outer diameter with a space between the peripheral surfaces of the arm, and a coating roller that is provided on the base end side of the arm and receives one end surface of the coating roller. It is characterized by comprising a copying flange larger than the outer diameter of.

[0010]

In such a structure, the copying flange is provided so that the position thereof can be changed in the axial direction of the arm, and the lock nut for restraining the end surface of the coating roller is moved in the axial direction of the arm on the tip side of the arm. Be prepared for it,
By changing the position of the lock nut, it is possible to change the axial length of the paint roller and change the paint width.

[0011]

FIG. 1 is a perspective view of a coating jig of the present invention, and FIG. 2 is a front view when it is set on a steel plate.

In the figure, a frame 1 using a steel wire or the like
A handle 2 is attached to one end of the arm, two arms 1a and 1b are extended in a direction opposite to the protruding direction of the handle 2, and coating rollers 3 and 4 are rotatably attached to the arms 1a and 1b, respectively.

The arms 1a and 1b are arranged so that their axes are located in the same plane including the axis of the handle 2, and
The relationship is an axis parallel to the axis of. And
Male screws 1a-1, 1b- are attached to these arms 1a, 1b.
1 is formed, and at the base end side thereof, copying flanges 3a, 4a for receiving one end surfaces of the coating rollers 3, 4 are rotatably provided. As shown in FIG. 2, these copying flanges 3a and 4a are retained by being screwed onto the male screws 1a-1 and 1b-1 respectively and loosely sandwiched between the retaining nuts 5a and 5b to enable rotation. Holding nuts 5a, 5
By changing the position of b, the copying flanges 3a, 4
The position of a can be changed.

The coating rollers 3 and 4 are made of a felt material which can be impregnated with a coating material.
It is rotatably attached around these arms 1a and 1b by penetrating b. The one ends of the coating rollers 3 and 4 are constrained at the other ends by a lock nut 5c screwed to the male screws 1a-1 and 1b-1 so as to abut on the copying flanges 3a and 3b. The binding force of the lock nut 5c is the same as that of the copy flanges 3a, 4
The frictional resistance due to the contact with a should not be applied.

FIG. 3 is a side view of the state where the handle 2 is positioned below the steel plate S, as viewed from the left side of FIG.

When the coating jig is set on the steel plate S, the end of the steel plate S is inserted between the coating rollers 3 and 4,
After that, as shown in FIG. 3, the handle 2 is turned so that the coating rollers 3 and 4 come into contact with the lower surface and the upper surface of the steel plate S in the figure. In FIG. 2, the coating roller 3 abuts on the upper surface of the steel plate S, and the other coating roller 4 abuts on the lower surface of the steel plate S. In both cases of FIG. 2 and FIG. 3, if the copying flanges 3a and 4a are abutted against the end portions of the steel plate S as shown in FIG. The direction can be positioned with respect to the steel plate S.

In the above structure, when the handle 2 is grasped and positioned so that the upper and lower surfaces of the steel plate S are held by the coating rollers 3 and 4 as shown in FIGS. The coating rollers 3 and 4 cover the coated surface of the steel plate S. Then, when the handle 2 is moved along the edge of the steel plate S in a state where the copying flanges 3a and 4a are abutted against the end of the steel plate S, the coating rollers 3 and 4 rotate and the peripheral edge of the steel plate S moves. Both the front and back sides can be coated simultaneously, and as shown in FIG. 4, coated surfaces A and B can be obtained on the front and back surfaces of the steel plate S, respectively.

In such a coating operation, since the copying flanges 3a and 4a follow the end portions of the steel plate S, the coating width of the coating rollers 3 and 4 is always kept constant, and the lengths of the coating rollers 3 and 4 are kept constant. Equalize and copy flanges 3a, 4
If the positions of a are also matched, the coated surface having the same width can be obtained on the front surface and the back surface of the steel plate S.

If the nuts 5a and 5b are moved to the left side in FIG. 2 to hold the copying flanges 3a and 4a and the coating rollers 3 and 4 also have a short axial length, the coating width can be reduced. On the contrary, if the copying flanges 3a and 4a are moved to the right and the coating rollers 3 and 4 are made long, a coating surface with a wide coating width can be obtained.

As described above, since both the front and back surfaces of the steel plate S can be simultaneously coated by the coating rollers 3 and 4, there is no need to reverse the steel plate S as in the conventional case, and the time required for coating is halved. And work efficiency is improved.
Further, by providing the copy flanges 3a and 3b,
Good coating that keeps the coating width uniform is possible, and the desired coating can be performed without requiring skill.

[0021]

According to the present invention, it is possible to simultaneously apply a uniform width on both the front and back sides of a flat plate-shaped product along the periphery thereof, and the coating can be completed in half the time compared with the conventional coating method. Therefore, the work efficiency is significantly improved.

Further, the coating width can be arbitrarily set by a combination of setting the position of the copying flange and changing the length of the coating roller, so that the coating surface can be formed according to the object to be coated. However, a good coated surface can be easily obtained.
