[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold block connecting mechanism, and more particularly to a technique effective when applied to, for example, a manifold block connecting mechanism for connecting adjacent pneumatic manifold blocks to each other.

[0002]

2. Description of the Related Art As a connecting mechanism of a manifold block of this kind, for example, there is the following one.

That is, the manifold block connecting mechanism has a stacking structure in which adjacent manifold blocks are connected to each other via connecting metal fittings or connecting screws.

[0004]

However, since the manifold block connecting mechanism described above has a stacking structure in which adjacent manifold blocks are connected to each other via a connecting bracket or a connecting screw, the manifold block is connected using a tool. There is a problem that the work has to be performed, the work is troublesome, and the workability is poor.

[0005] For this reason, there has been a problem that the manifold blocks adjacent to each other cannot be reliably connected.

SUMMARY OF THE INVENTION An object of the present invention is to provide a manifold block connecting mechanism which can eliminate a tool, facilitate connecting work, and improve workability.

Another object of the present invention is to provide a manifold block connecting mechanism that can reliably connect adjacent manifold blocks.

[0008] The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0009]

Means for Solving the Problems Of the inventions disclosed in the present application, the outline of a representative one will be briefly described.
It is as follows.

That is, the manifold block connecting mechanism of the present invention has a structure in which adjacent manifold blocks are provided with a built-in fluid pressure clamper for connecting these manifold blocks by fluid pressure.

[0011] In this case, the fluid pressure clamper is provided with a locking claw provided on one of the manifold blocks adjacent to each other, a locking hole provided on the other, and an operation for temporarily fixing the locking claw and the locking hole. A structure including a lever and a fluid pressure cylinder portion for locking a hook state between the locking claw and the locking hole can be provided.

[0012]

According to the manifold block connecting mechanism of the present invention described above, since the manifold blocks adjacent to each other are provided with a built-in fluid pressure clamper for connecting these manifold blocks by fluid pressure,
With the built-in fluid pressure clamper, the manifold blocks adjacent to each other can be easily connected.

[0013] Therefore, it is possible to eliminate the need for tools, to facilitate connection work, and to improve workability.

Further, since the connection state is locked by the built-in fluid pressure clamper, the adjacent manifold blocks can be reliably connected to each other.

In this case, the fluid pressure clamper is provided with a locking claw provided on one of the adjacent manifold blocks, a locking hole provided on the other, and an operation for temporarily fixing the locking claw and the locking hole. Since the structure includes the lever and the fluid pressure cylinder portion that locks the hook state between the locking claw and the locking hole, the structure can be simplified by using the fluid pressure from the common input port.

have. The air flow path 1 is provided at the upper end of the cylinder chamber 7.
The air flow path 11 communicates with a common input port, and a piston 10 with an O-ring 9 is slidably provided on the inner peripheral surface.

A groove 12 extending in a direction perpendicular to the stacking direction is formed at the lower end of the piston 10, and an operation lever 14 having an operation rod 13 having a semicircular cross section is pivotally supported in the groove 12. The lever 14 has a function of inverting the operation rod 13 having a semicircular cross section upward or downward by operating the lever 14 to raise or lower the piston 10 of the pneumatic cylinder portion 6.

Reference numeral 8 denotes a blind cover, and A and B denote output ports for solenoid valves, respectively.

Next, the operation of this embodiment will be described.

FIG. 4 is a sectional view showing a first step taken along line IV-IV in FIG. 2, FIG. 5 is a sectional view showing a second step taken along line IV-IV in FIG. 2, and FIG. 7 is a cross-sectional view showing a third step taken along line IV, FIG. 7 is a cross-sectional view showing a first step taken along line VII-VII of FIG. 3, and FIG. 8 is a second step taken along line VII-VII of FIG. FIG. 9 is a sectional view, and FIG.
FIG. 14 is a cross-sectional view showing a third step along the I line.

In the above configuration, the connection between the adjacent manifold blocks 1a and 1b is performed through the following steps.

That is, in the first step, as shown in FIGS. 4 and 7, first, the second manifold block 1
When the operation lever 14 is inverted to the open position at (b), the operation rod 13 having a semicircular cross section hits the groove 12 and the piston 10 moves up.

Next, the second manifold block 1b
The engaging claw 4 of the first manifold block 1a is inserted into the engaging hole 5 so that the hook 4a faces the hook hole 5a.

In the second step, as shown in FIGS. 5 and 8, in the second manifold block 1b, when the operating lever 14 is inverted to the lock position, the operating rod 13 having a semicircular cross section is inverted downward. Then, the locking claw 4 is pushed down so that the hook portion 4 a is hook-engaged with the hook hole 5 a of the locking hole 5.

As a result, the first and second manifold blocks 1a and 1b adjacent to each other are temporarily connected, and the piston 10 can be lowered.

The same operation as in the first and second steps is performed in all the other manifold blocks adjacent to each other.

In the third step, as shown in FIGS. 6 and 9, when air is supplied to the common input port, the first and second manifold blocks 1a and 1b adjacent to each other are supplied.
, The air pressure in the cylinder chamber 7 causes the piston 10
Is lowered, and the locking claw 4 is completely locked in the locking hole 5.

As described above, the first and second manifold blocks 1a and 1b adjacent to each other can be easily connected by the built-in pneumatic clamper 2.

Therefore, it is possible to eliminate the need for tools, to facilitate the connecting operation, and to improve the workability.

Further, since the connection state is locked by the built-in pneumatic clamper 2, the first and second manifold blocks 1a and 1b adjacent to each other can be connected reliably.

Further, the pneumatic clamper 2 includes a locking claw 4 provided on the first manifold block 1a,
The structure provided with the locking hole 5, the operation lever 14, and the pneumatic cylinder portion 6 provided in the manifold block 1b of the above can be simplified by utilizing the air pressure from the common input port.

Although the invention made by the present inventors has been specifically described based on the embodiments, the invention is not limited to the above-described embodiments and can be variously modified without departing from the gist of the invention. Needless to say, there is.

For example, in the above-described embodiment, the case where the locking pawl is provided on the connecting surface of the first manifold block and the locking hole is formed on the connecting surface of the second manifold block has been described. An engaging hole can be formed on the connecting surface of the first manifold block, and an engaging claw can be provided on the connecting surface of the second manifold block.

In the above embodiment, the case where the hook portion of the locking claw is locked in the hook hole portion of the locking hole and the hook state is locked by the piston of the pneumatic cylinder portion has been described. Instead, a tapered surface is formed in the hook portion of the locking claw, and the operation of the tapered surface allows the manifold blocks adjacent to each other to be connected more firmly.
