Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reciprocator for painting a hose in which a hose for supplying paint or air to the spray gun is built in a reciprocator that reciprocally drives the spray gun.

[0002]

[Prior art]

 Conventionally, when connecting a hose for feeding paint or air to a spray gun attached to a reciprocator, for example, in a vertical reciprocator, as shown in FIG. The hose a is connected to the gun b, and the hoses a are bundled into a single hose so as to have an appropriate slack, and the middle of the hose is fixed to a mounting portion c provided on the reciprocator.

In a horizontal type reciprocator, as shown in FIG. 4, hoses a are bundled and pulled into a cover d of the reciprocator, and the hoses a are inserted into a flexible protective tube e. The hose a is housed freely in the cover d while being protected, and the tip of the hose a projecting from the protective tube e is pulled out through the running opening groove g of the reciprocating arm f formed in the cover d to make a spray. I was trying to connect to gun b.

[0004]

[Problems to be solved by the device]

 In the case of the vertical reciprocator shown in FIG. 3, the hose a itself and the weight of the paint passing through the hose a always apply a load to the connection part of the hose a with the spray gun b and the fixed part to the mounting part c. There was a defect that a was easily broken in those parts.

Also, in the example of the horizontal reciprocator shown in FIG. 4, the hose a protruding and exposed from the protective tube e is pulled out from the narrow opening groove g, and the hose a moves along with the movement of the reciprocating arm f. Since the hose a was rubbed against the rim of the opening groove g, the hose a could also be damaged. Further, there is a drawback in that dust of the paint that has risen up adheres to the hose a protruding from the opening groove g and is easily accumulated and falls on the object to be coated.

[0006]

[Means for Solving the Problems]

 The reciprocator for painting with a built-in hose of the present invention was devised in view of the above points, and a reciprocating arm that penetrates through an opening groove formed in the cover and is reciprocally driven along the opening groove. Inside the cover of the paint reciprocator with a spray gun attached to the end of the hose, multiple hoses were inserted into a flexible protective tube and accommodated freely, and one end of each hose was provided on the cover. In addition to connecting to the hose joint, the reciprocating arm was made hollow, and the other end of each hose protruding from the protective tube was inserted into the reciprocating arm and connected to the spray gun.

[0007]

[Operation and effect of the device]

 When the reciprocating arm reciprocates, the part of the hose housed in the cover of the reciprocator moves in the cover while being protected by the protective tube, and also the part that penetrates the opening groove of the hose and projects to the outside. Is inserted into the hollow reciprocating arm and protected by the reciprocating arm itself, that is, the moving part of the hose is completely protected by the protective material, so that the hose is not rubbed and damaged. To be prevented.

Further, unlike the conventional method of suspending and fixing the hose, an excessive load is not applied to a part of the hose, so that the hose is prevented from being damaged.

In addition, since the hose can be built in and piped in advance from the hose joint provided on the cover to the tip of the reciprocating arm, the hose can be installed from the tip of the reciprocating arm at the reciprocator installation site. Simply connect the projecting built-in hose to the spray gun, and connect the supply hose drawn from the paint supply and the air supply to the hose joint of the cover, which makes piping work on site extremely easy. .

Further, when applied to the horizontal reciprocator, the surface area of the protruding portion becomes smaller than that when the hose protruding from the opening groove of the cover is covered with the reciprocating arm and the hose protrudes by being exposed. As a result, the amount of dust that adheres to the paint is reduced, and the amount of paint that falls on the object to be coated can be reduced.

【Example】

 An embodiment in which the present invention is applied to a horizontal reciprocator will be described below with reference to FIGS. 1 and 2.

In FIG. 1, reference numeral 1 is a cover of a reciprocator, and a reciprocating arm connected to a reciprocating drive device (not shown) from an opening groove 2 formed in the lower surface of the cover 1 along the length direction. 3 projects downward and reciprocates in the direction of the arrow along the opening groove 2, and a pair of spray guns 5 can be attached to the lower end of the reciprocating arm 3 via a fixture 4. ing.

As shown in FIG. 2, the reciprocating arm 3 includes a hose joint 8 having four connecting ports 9 communicating with each other on both inner and outer surfaces of the arm body 7 formed of a pipe. The hose 12 has a structure in which the four hose 12 with a built-in arm are inserted into the arm body 7, and both ends of each hose 12 are connected to the inside of the front and rear hose joints 8. The connection ports 9 are separately connected.

In the above-mentioned cover 1, four cover built-in hoses 13 are movably accommodated by being inserted into a flexible protection tube 14, and one end side of each hose 13 is The hose joint 8 is connected to the outside connection ports 9 of the hose joint 8 at the rear end of the reciprocating arm 3 described above, and the other end side of the same hose joint 8 is attached to the cover 1 at a predetermined position. It is connected to the inner connection port 9.

Further, a separate connection hose 15 is provided between the outer connection port 9 of the hose joint 8 at the tip of the reciprocating arm 3 and the paint supply port and the air supply port of each spray gun 5. It is connected.

This embodiment has such a structure. When a hose joint 8 provided on the cover 1 is connected to a supply hose drawn from a paint supply source and an air supply source (not shown), a hose 13 with a cover and a built-in arm Paint and air are supplied to each spray gun 5 through the hose 12 and the connection hose 15, respectively.

When the reciprocating arm 3 reciprocates, the hose 13 with a built-in cover moves inside the cover 1 while being protected by the protection tube 14, and the hose 12 with a built-in arm is protected by the reciprocating arm 3 itself. As a result, there is no possibility that the hoses 12 and 13 are rubbed by the reciprocating drive device or the opening groove 2 and damaged.

The hose 13 with a built-in cover and the hose 12 with a built-in arm can be preliminarily piped in the cover 1 and the reciprocating arm 3, respectively, and at the installation site of the reciprocator, the tip of the reciprocating arm 3 can be installed. It is enough to connect the hose joint 8 of No. 1 and the spray gun 5 with the connecting hose 15, and also to connect the supply hose drawn from the paint supply source and the air supply source to the hose joint 8 of the cover 1. The piping work in the is extremely easy.

In the portion of the hose protruding from the opening groove 2 of the cover 1 and connected to the spray gun 5, a part of the hose is covered by the reciprocating arm 3 as the hose 12 with a built-in arm. Compared to the case where the hose was pulled out from the opening groove and connected to the spray gun, the surface area of the protruding portion was smaller, and the amount of paint dust that had floated up was reduced, so that the paint was deposited on the object to be coated. The number of falling defects is reduced.

The present invention can be applied to a vertical reciprocator as well.
