Description

[Detailed description of the invention] The present invention relates to a valve inspection device.

In FIG. 1 the pulp (1) is shown. That is, inside the ring-shaped main body (2), a pair of bearing devices +31 (41) are disposed so that the square (5) can be opened and closed, and the main body (2)
) K is provided with an operating device (6) for opening and closing the diarrhea valve.

^ Such pulp (1) is inspected immediately after production.

That is, it is checked whether there is any leakage with the valve (5) closed. Conventionally, such inspections have been carried out manually, which is inefficient and cannot be expected to be accurate.

The present invention proposes a valve inspection device that can solve the above problems.

In other words, the present invention has a valve mounting table having an air supply port configured to be movable between a valve delivery position and a leak detection position, and a pulp holding device and a solution supply device are installed at the leak detection position. The present invention provides a valve inspection device equipped with a valve inspection device. According to this configuration, the mounting table on which the pulp is placed is moved in a short distance to the detection position, and with the upper surface of the pulp being held down by the pulp pressing device, the solution is supplied to the upper surface side of the pulp, and the lower surface of the pulp is By pressurizing the side with air from the air supply port, the pulp leakage test can be performed mechanically and efficiently, and a more accurate test can be expected.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 8. Reference numeral (7) designates the inspection section frame. A pair of left and right rails (8) are laid on the top surface of the inspection section frame. A valve mounting table (9) guided by these rails (8) allows the valve to be opened by the operation of the cylinder device (11). It is configured to be movable between the delivery position tft++21 and the leakage detection position (1□□□.O1
There is an air supply port (

An inspection section frame (7) is provided opposite to 12E so as to be perpendicular to the inspection section frame (7). This relocation part frame 1° (81D is a pair of left and right rails 13g) is installed, and between these rails are wheels (4
A movable table (41) guided via 01 is provided. This movable table (411) is moved between the above-mentioned pulp delivery position 1 tOa and the transport conveyor (41) disposed below the transfer section frame (2) by the operation of the moving cylinder device +421 provided between the transfer section frame (1). The forward movement limit of the movable table (41) is the cough movable table f4.
It is determined by bringing the stopper body attached to I into contact with the stopper body (451KVi) provided on the relocation part frame (to). An elevating table (461) is attached below the movable table 141. That is, the elevating table (It passes through the cylinder (481) housed in the vertical slide rod (471 is the movable table 141) that stands up from the top of the fence, and the end stopper (481) for preventing falling is attached to the upper end of the slide rod 14η.

The conveyor 1431 consists of an upper conveyor section (end), a lower conveyor section (6 holes), a starting end elevating conveyor section, and an end elevating conveyor section B, and the valve (1) is transported by a pallet 162.
It is done through.

The action will be explained below. The valve to be inspected (
1) is the pulp delivery position (12) V by crane etc.
c carried. Here, at the pulp delivery position (14), a valve mounting table (9) is located due to the extension of the cylinder device (Ill).Furthermore, the valve mounting table (9) is pivoted by the operation VC of the swinging device (19). (2d) and is tilted as shown by the imaginary line in FIGS. 4 and 5.

Because of this inclination, it is easy to transfer the valve (1) from the glue lanes.

Also pulp mounting table (91K 51. Pulp (1)
is positioned by the protruding piece (241), and ff1ifl+ is blocked.Then, the valve mounting table (9) is positioned as shown in FIGS. 4 and 5.
It is returned to the horizontal position as shown by the solid line in the figure. Then, due to the contraction of the cylinder device (II), the valve mounting table (9) is moved to the leak detection position f t+31 K #, thereby moving to a position opposite to the pressure receiving plate (width) for the pulp (1). Pressure receiving plate (
The scream is adjusted according to the size of the pulp (1). That is, if the pulp (1) has a large diameter, it remains as is, but if it has a small diameter, a corresponding auxiliary pressure receiving member head is attached. Its installation is done in the pressure receiving plate (Sho's hollow part (311
Insert the auxiliary pressure receiving member @, and rotate the auxiliary pressure receiving member ζ to engage the engagement protrusion Cl41 with the protrusion C3'h,
This is then done by inserting the bin ia). With the pulp (1) positioned below the pressure-receiving plate (Incorporated), the lifting cylinder device (29) is extended from 1 to 1, and the pressure-receiving plate is lowered to press the pulp (1) onto the upper surface of the pulp (1). As a result, the pulp (1) is placed between the valve mounting table (9) and the pressure receiving plate (30).
It is squeezed by. In this state, a solution such as soap liquid is supplied into the pulp (1) through the hollow part t311 by using the solution supply device. At this time, the valve (5) of the pulp (1)
) is closed, so the solution is located on the top side of the valve (5). Next, air is forced into the lower surface of the valve (5) through the air supply port.If the valve (5) is incorrect at this time, air leakage will occur and the liquid will foam. If the i! is accurate, there will be no fuss. This allows the leakage test to be carried out. After the test is complete, the pressure receiving plate (?A) is raised, and the valve mounting table (
9) is moved and the pulp (1) is moved to the valve delivery position (1).
2). At this time, the moving cylinder device 142
1, the movable metal (41) moves to the valve delivery position [1
Therefore, the pulp (1) is located at both pulp lifting plates 155) tR as shown in FIG.
I will do it. Next, the lifting platform (461) is lowered by the operation of the lifting cylinder device group, and the pulp holding plate (5η) is brought into pressure contact with the upper surface of the pulp (1).Then, the cylinder device f
+541 f Activate both slide levers (531
are moved toward each other to bring the pulp lifting plate (55) into contact with the outer peripheral surface of the pulp (1). Next, the lifting platform (fence) is raised, and the pulp lifting plate (kasumi) is engaged with the protrusion of the pulp (1) to lift the pulp (11).
In 1), the swinging and the like are regulated by the pulp holding plate f571. Due to the contraction of the moving cylinder device (14), the pulp (1) is transferred to the upper part of the starting end lifting conveyor section by the movement VC of the moving cylinder (14), and then the lifting table 146) is lowered and the valve holding plate 65) is separated. Pulp (1

It will be dropped to G21. The pulp (1) on which the pulp (1) is placed is transferred via the upper conveyor section to the terminal elevating conveyor section +611ff, where the pulp (1) is unloaded from the pants) +67J. empty pants) +6
21 is returned to the starting end lifting conveyor section ((support)) via the lower conveyor section (5 (support)).

According to the above-mentioned Komei, the mounting table on which the pulp is placed is moved to the detection position, and while the upper surface of the pulp is pressed by the pulp pressing device, a solution is supplied to the upper surface of the pulp, and the pulp is By pressurizing the lower surface of the pulp with air from the air supply port, the pulp can be mechanically tested for leaks with a high Tik rate, and more accurate tests can be expected.

In addition, by adopting an annular pressure receiving plate as shown in the embodiment, it is possible to easily supply the solution by utilizing the hollow part of this pressure receiving plate, and furthermore, the configuration allows for attaching and detaching the auxiliary pressure receiving member to the pressure receiving plate. This makes it possible to handle pulp of various diameters.
