BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint supply device, and more particularly to a manifold in the paint supply device.

[0002]

2. Description of the Related Art With the increasing number of colors applied to automobiles and the like, it becomes necessary to successively change colors with a single coating machine, and therefore the coating machine of a desired color is switched and supplied. A paint supply device has been proposed (for example, Japanese Patent Laid-Open No. 57-2
(See Japanese Patent Publication No. 00768). The paint supply device schematically shown in FIG. 5 is provided with a manifold 2 provided with a paint passage 3 communicating with the painter 1, and a plurality of paint valves for supplying different paints to the paint passage 3 in the manifold 2. By arranging 4, ... And selectively operating these paint valves,
A paint of a desired color is supplied to the coating machine 1 from any one of the paint valves 4. Then, when changing the color to be painted in this paint supply device, in order to prevent color mixture, a cleaning liquid such as thinner is poured from the base end 5 side of the paint flow path 3 to wash the paint flow path 3. However, since the number of paint valves installed in the paint supply device, in other words, the number of colors required for coating varies depending on the object to be coated, in the above-mentioned known paint supply device, the length depends on the number of paint valves required. There is a problem that a plurality of different types of manifolds are required.

In order to solve this problem, it is conceivable to connect a plurality of manifold bases having paint valves in series according to the required number of paint valves. However, the manifold bases are connected or the manifold bases are connected. In order to easily and quickly increase or decrease the number of the manifolds, special consideration needs to be given to the connecting means of the manifold base.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a paint supply device having a connecting means for easily connecting and increasing / decreasing the manifold base.

[0005]

In order to solve the above-mentioned problems, the present invention provides a manifold having a paint flow path leading to a painting machine with a plurality of paint valves for supplying different color paints to the paint flow path. And a paint supply device for supplying a paint of a desired color to the coating machine by selectively operating these paint valves, in the manifold, the paint passage, the paint valve, and both side surfaces in the connecting direction. A manifold base having a connector insertion portion that is formed in a lateral direction is formed as a series of a desired number of paint valves, and the connector that connects the manifold bases is connected to both ends in the axial direction. An intermediate coupling body having engaging portions that can be engaged, and an axial length between engaging surfaces of these engaging portions is substantially equal to a width in a continuous installation direction of the manifold base; The end part with a bolt at the other end Configure I, a continuously provided to the manifold base, is characterized in that linked together by nut is screwed mutually engaged so bolts of the coupling member engaging portion.

[0006]

Operation: The manifold bases are connected according to the required number of paint valves, and the connecting body in which the intermediate connecting body and the end connecting body are connected by mutual engagement of these engaging portions is connected in series. By inserting the nuts into the bolts of the end connecting body by inserting the base into the connecting body insertion portion of the base, the desired number of manifold bases connected in series are integrally connected. in this case,
Since these connecting bodies can be connected by mutual engagement of the engaging portions provided in each connecting body, no tools are required,
Easy to connect. Further, since the connecting body can be inserted into the manifold bases that are continuously provided from the opening on the side of the connecting body inserting portion, the connecting body can be easily attached to the manifold base.

1 to 4 show an embodiment of the present invention, in which a paint supply device includes a manifold base 12 having a paint flow passage 13 leading to the coating machine 1, ... With each manifold base 12
And a paint valve 1 for supplying a different color paint to the coating machine 1.
4, 14 are installed.

The manifold base 12 has the paint passage 13 penetrating in the connecting direction and the connector insertion portions 15, 15 which are substantially parallel to the paint passage 13 formed on both side surfaces in the connecting direction and open sideways. , And an opening 16 for mounting the paint valve 14.

The connecting body 20 for connecting the manifold bases 12, ... Is composed of a desired number of intermediate connecting bodies 21 ,. The intermediate coupling body 21, which is shown in detail in FIG. 2, has a rectangular cross section, and has key-shaped engaging portions 23, 2 facing opposite directions at both axial ends.
3, the length 1 between the engaging surfaces 23a, 23a of the engaging portions 23, 23 that engage with each other is substantially equal to or slightly shorter than the width b of the manifold base 12 in the connecting direction. Has been done. The end connection body 21 includes the engagement portions 23,
Mutual engagement of the engaging portions is easy because there is no directivity in the connecting direction because the 23 are oriented in opposite directions. On the other hand, the end connecting body 22 is the same as the intermediate connecting body 21 except that the end connecting body 22 has the engaging portion 23 at one end and the bolt 24 to which the nut 25 is screwed at the other end, as shown in detail in FIG. It has the configuration of. Therefore, it is possible to connect to the left and right of the intermediate connector by one kind of connector 22. The paint valve 14 attached to the opening 16 has the same structure as the paint valve in a known paint supply device.

In the above embodiment, the manifold base 12 is connected in a desired number of paint valves, and the required number of intermediate connectors 2 are provided in the connector insertion portions 15 ,.
.. and the end connecting bodies 22, 22 are connected by mutual engagement of the engaging portions 23, 23 of these connecting bodies, and the connecting body 20 is inserted, and the manifold plates 12, 12 at both ends are provided with sub-plates. 27, 27 are brought into contact with each other, and the end connector 22,
22 by screwing nuts 25, ... to the bolts 24 ,.
・ Is integrally connected. In this case, the connecting body 20 includes the engaging portions 23, ...
.. can be connected by mutual engagement, and can be inserted into the manifold base 12, ..
It is easy and quick to connect 2, ...

[0011]

The paint supply device of the present invention can form a manifold corresponding to the paint color of the object to be painted by connecting one type of manifold base according to the number of paint valves required. The score can be reduced. Further, since the connecting body can be configured by mutual engagement of the engaging portions, the manifold base can be easily connected and increased / decreased.
