[Prior art]

 With the increasing number of colors in automobiles, it is necessary to change the colors one by one with a single coating machine.Therefore, there is a paint supply device that supplies the coating machine with the desired color by switching it. It has been proposed (for example, see Japanese Patent Laid-Open No. 57-200768). In the paint supply device outlined in FIG. 5, a manifold 2 is provided with a paint flow path 3 communicating with the coating machine 1, and a plurality of paint flow paths 3 for supplying different color paints to the paint flow path 3 are provided in the manifold 2. By arranging the paint valves 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 mixing, a cleaning liquid such as thinner is poured from the base end 5 side of the paint flow path 3 to clean the paint flow path 3. To do. However, the number of paint valves installed in the paint supply device, in other words, the number of colors required for painting, differs depending on the object to be coated. There is a problem that multiple types of manifolds with different types are required.

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

[Problems to be solved by the device]

 The problem to be solved by the present invention is to provide a paint supply device having a connecting means that allows easy connection and increase / decrease of the manifold base.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a manifold having a paint flow path leading to a coating machine with a plurality of paint valves for supplying different color paints to the paint flow path. In a paint supply device for selectively operating a valve to supply a paint of a desired color to a coating machine, a side where the manifold is formed on both sides of the paint passage and the paint valve in the connecting direction. A manifold base having a connector insertion portion that is open at one side is configured as a series of desired paint valves, and the connector that connects the manifold bases can be engaged with each other at both axial ends. An intermediate connecting body having engaging portions and having an axial length between engaging surfaces of these engaging portions substantially equal to a width in a continuous installation direction of the manifold base, and the engaging portion at one end in the axial direction and the other end at the other end. It is constructed by connecting with an end connecting body that has a bolt on The two hold base, is characterized in that linked together by nut is screwed mutually engaged so bolts of the coupling member engaging portion.

[0006]

[Action]

 The manifold bases are connected according to the number of paint valves required, and the connecting body that connects the intermediate connecting body and the end connecting body by mutual engagement of these engaging parts is connected to the connected manifold bases. When inserted into the body insertion portion and screwed nuts onto the bolts of the end connecting body, a desired number of consecutively connected manifold bases are connected together. In this case, since these connecting bodies can be connected by mutual engagement of the engaging portions provided on the respective connecting bodies, no tools are required, so the connecting operation is simple. Further, since the connecting body can be inserted into the manifold bases that are continuously provided through the opening on the side of the connecting body insertion portion, the connecting body can be easily attached to the manifold base.

【Example】

 1 to 4 show an embodiment of the present invention. In this paint supply device, a manifold 11 having a paint flow passage 13 leading to the coating machine 1 is connected to a desired number of manifolds 11. Each manifold base 12 is provided with paint valves 14, 14 for supplying a different color paint to the painting machine 1.

The manifold base 12 has the paint passage 13 penetrating in the connecting direction, and the connector insertion portion 15, which is substantially parallel to and parallel to the paint passage 13 formed on both side surfaces in the connecting direction. 15 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, 23 facing in opposite directions at both axial ends, and these engaging portions are engaged with each other. The length 1 between the engaging surfaces 23a of the engaging portions 23, 23a is substantially equal to or slightly shorter than the width b of the manifold base 12 in the connecting direction. In the above-mentioned end portion coupling body 21, since the engaging portions 23, 23 face in mutually opposite directions, there is no directivity in the connecting direction, so mutual engagement of the engaging portions is easy. 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-described embodiment, the manifold base 12 is connected by a desired number of paint valves, and the required number of intermediate connectors 21, ..., And ends are provided in the connector insertion portions 15 ,. The connecting body 20 is formed by connecting the connecting bodies 22 and 22 by the mutual engagement of the engaging portions 23 and 23 of these connecting bodies, and the sub plates 27 and 27 are brought into contact with the manifold bases 12 and 12 at both ends. , And the nuts 25, ... Are respectively screwed onto the bolts 24, ... Of the end connecting bodies 22, 22, so that the manifold bases 12 ,. In this case, the coupling body 20 can be coupled by mutual engagement of the engaging portions 23, ... Provided in each coupling body without using a tool, and the coupling body inserting portions 15, 15 side Since it can be inserted into the manifold bases 12, ...
