Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hanging jig for a spray gun for spraying glaze on the surface of, for example, ceramics.

[Conventional technology]

In the process of manufacturing a ceramic product, a glaze is applied to the surface of the dried green body before firing. As a method, a method of spraying glaze with a spray gun is generally adopted.

For example, FIG. 7 shows an example of the work, in which the operator manually operates the spray gun 3 to spray the glaze on the dry green body 2 placed on the rotary table 1. 4 in the figure
Is a hose for supplying the glaze and pressurized air to the spray gun 3, and 5 is a booth for preventing the glaze from scattering.

As described above, conventionally, the operator holds the spray gun 3,
I was glazing it while moving it up and down, left and right, taking care to avoid spray spots.

[Problems to be solved by the device]

However, such a conventional method has the following problems.

The total weight of the spray gun that the operator must carry (the weight of the spray gun and the glazed hose) is, for example, about 1 kg.
Because of the heavy weight, work illness (arms and back pain) occurred frequently, and work efficiency decreased.

Since the total weight of the spray gun is heavy, it is necessary to hold the spray gun in a state of being close to the human body, and it is easy to inhale dust, which is not preferable from the viewpoint of worker's hygiene.

Comparing the first half and the second half of the operating time of the worker,
Since the latter half was tired, the work time per product was long and the work efficiency was low.

Therefore, an object of the present invention is to provide a spray gun suspension jig that reduces worker fatigue, improves the work environment, and improves work efficiency.

[Means for Solving the Problems]

In order to achieve this object, the spray gun suspension jig of the present invention comprises a balancer for vertically suspending the spray gun and a barrel of the spray gun by a pulling force that reduces the total weight of the spray gun and the hose. It is characterized in that it comprises a fulcrum which is supported so as to be raised and lowered, and a ring having a free ring which supports the barrel so as to be tiltable in the left-right direction, and a hanging string from the balancer is connected to the free ring of the ring.

〔Example〕

Hereinafter, the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a schematic view showing an embodiment of the present invention. In the figure, reference numeral 1 is a rotary table, on which a dry green substrate 2 is placed. 3 is a spray gun, 4 is a hose for supplying glaze and pressurized air to the spray gun 3, and 5 is a booth for preventing the glaze from scattering. In the present invention, the balancer 6 is attached to the ceiling above the booth 5, and the spray gun 3 is connected to the lower end of the hanging string 7. As the balancer 6, a spring type can be used. As a result, the total weight of the spray gun 3 and the hose 4 is reduced, and the spray gun can be operated with a light supporting force.

When connecting the hanging strap 7 to the spray gun 3 through a hole provided in the ceiling of the booth 5, if the hanging strap 7 is only a hole, the hanging strap 7 will be worn at the inner circumference circle of the ceiling hole of the booth 5 when operating the spray gun 3. However, there is a risk of fraying and breaking. For this reason, the suspension cord 7 is directly passed through the center hole of the pipe 10 having the rotatable ball 9 in the center by the support plate 8 and the booth 5
To prevent it from coming into contact with the ceiling hole (see FIG. 2). As the hanging string 7, a material that is strong and does not obscure the field of view, such as nylon fishing line or piano wire, can be used. Friction can be reduced by using a material having a smooth surface such as a ceramic insulator having a glaze as the material of the pipe 10.

Next, when the lower end of the hanging strap 7 is directly connected to the spray gun 3, as shown in FIG. 6 (a), when the spray gun 3 is swung left and right in the same manner as the movement of the wrist, the center of gravity of the spray gun 3 is changed. I feel resistance as the position moves up and down. Also, the sixth
As shown in FIG. 6B, resistance also occurs when the spray gun 3 is moved back and forth.

Therefore, in this embodiment, as shown in FIG. 3, a hook metal fitting 11 having engaging portions at both ends and the hook metal fitting 11 are provided.
And an arcuate ring 12 having a ring 12a whose both end engaging portions are rotatably engaged with each other, and an idle ring 13 slidably attached to the ring 12.
Is provided, and the twist return 14 attached to the lower end of the hanging string 7 is connected to the loose coupling ring 13. The loose ring 13 is preferably made of a fluororesin having a small abrasion resistance.

As shown in FIG. 4, the hook metal fitting 11 having such a structure is attached to the main body of the spray gun 3 with the adjusting screw 15. FIG. 5 is a side view.

With the above-described structure, the spray gun 3 can be pivoted around the ring 12a as a fulcrum without vertically moving the hanging string 7, and when the tilting is performed left and right, the position of the hanging string 7 remains unchanged. By smoothly sliding the ring 12 in the loose ring 13, the spray gun 3 can be tilted freely. In this way, by supporting the spray gun 3 on the hanging string 7 from the balancer 6 so as not to hinder the movement of the spray gun 3 due to the movement of the wrist of the operator, the weight of the spray gun 3 is reduced and the burden on the operator is increased. Can be reduced.

For example, with the device of this embodiment, the total weight of the spray gun can be reduced from about 1 kg to 250 g, and work illness (arm and back pain)
Was reduced.

Also, comparing the first half and the second half of the operating time of the worker, the working time per product does not become long in order to reduce the total weight of the spray gun and improve the operability.

By attaching the jig of the present invention together with the spray gun to the tip of the painting robot, it is possible to prevent the robot hand from being overloaded.

[Effect of device]

As described above, in the present invention, the spray gun and the glazed hose are hung by the hanging string via the balancer.
In addition, by supporting the spray gun tiltably in the front-rear and left-right directions with a ring, the total weight of the spray gun is reduced and the burden of wrist movements is lightened, and work illness (arms and back pain) can be reduced. Is improved.
Furthermore, by reducing the total weight of the spray gun, it is possible to extend the hand so that the dust from the glaze etc. sprayed from the spray gun is significantly reduced, the adverse effect on the human body can be reduced, and the working environment can be improved. You can

Further, even when comparing the first half and the second half of the operating time of the worker, since the total weight of the spray gun can be reduced, the working time per product does not become long, so the working efficiency is improved.
