[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net-shaped object holding device, and can be applied to, for example, a flat-shaped air filtering net holding device when inspected.

[0003]

2. Description of the Related Art Conventionally, when a mesh filter (hereinafter referred to as a work) is imaged by a video camera and optically inspected, the work is generally held by an inspection jig. If the held work is warped at this time, the height of the focus on the entire work surface becomes non-uniform, and a correct inspection result cannot be obtained. Therefore, the warped work is manually corrected and held by a jig, or is pressed by glass or the like.

The work after the inspection is transferred from the inspection jig onto the ejection table, and is ejected while being inclined in different directions according to the inspection result. As a result, the work is sorted into a good product or a defective product. When the ejection table rotates to change the ejection direction of the work, the work slips due to inertia, and the work may slip or drop from the ejection table. In order to prevent this, a method of providing a rotation stopper stopper for the work on the discharge table or a method of directly clamping the work and removing the clamp after rotation has been adopted.

[0005]

However, in order to manually correct the warp of the work, it is necessary to have experience and intuition, and there is a problem that the manual work takes time. There are multiple types of work shapes, and different warps are manually corrected according to the types. Therefore, it is difficult to automate the work inspection.

On the other hand, the method of pressing the work with glass is
There is a drawback that a dedicated mechanism is required, the configuration is complicated, and a space for arranging the mechanism is required. Also, it is necessary to clean the glass regularly. Furthermore, since a dedicated glass presser is used, it is necessary to change the glass presser each time the type of work is changed.

Next, as a measure for preventing slipping of the work, the method of providing the stopper for rotation on the discharge table requires a mechanism for inclining the discharge table and removing the stopper when discharging the work. The problem was that it became complicated. In addition, this method requires a stopper according to the type of work, so when changing the type of work,
There is a drawback in that the work of changing the stopper is required and it is complicated. On the other hand, in order to directly clamp a work, a clamp mechanism and a drive unit according to the type of work are required. For this reason, when changing the type of the work, there is a drawback that the work of changing the clamp mechanism and the drive unit is required, which is complicated.

The present invention has been made in consideration of the above points, and a net-shaped object holding device capable of holding a net-shaped object by correcting the warp and slippage of the net-shaped object due to inertia during rotation. An object is to propose a net-shaped object holding device which can be prevented with a simple structure.

[0009]

In order to solve such a problem, in the present invention, the peripheral part mounting means mounts the net-shaped object on the peripheral part of the net-shaped object. The clamping means clamps the peripheral portion of the net-shaped object on the peripheral-portion mounting means to hold the net-shaped object. The central portion mounting means moves up and down to the opening formed on the inner peripheral surface of the peripheral portion mounting means, and mounts the net-shaped object at the central portion of the net-shaped object.

Further, according to the present invention, a mounting means for mounting a net-shaped object is disposed on the elevating and rotating table which moves up and down and rotates. Further, on the ascending / descending rotation means, there is provided a mesh insertion means having a plurality of wire rods each having a tip end directed upward, and inserting the tip end into a mesh opening of a mesh-shaped object.

[0011]

The central portion mounting means is elevated to the opening of the peripheral portion mounting means and regulates the height of the central portion of the net-shaped object to a predetermined height according to the peripheral portion mounting means. Then, the peripheral portion of the net-shaped object is clamped by the clamping means on the frame. As a result, the net-shaped object is
The warp is corrected and held by the peripheral mounting means.

When the lifting / lowering and rotating means is raised to place the net-shaped article on the placing means, the mesh insertion means inserts and holds the tip of the wire into the mesh opening of the net-shaped article. This makes it possible to prevent the net-shaped object from slipping due to inertia when rotating with a simple configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 shows a filter inspection system for inspecting a plate-like net-like object as a whole, for example, a rectangular work 2. In the filter inspection system 1, two rails 4 and 5 are laid in parallel on a rectangular base 3 placed on a pedestal. The filter inspection system 1 places a work 2 on a holding device, for example, a supply device 6 for the work 2,
It is conveyed to the inspection device 7 along the rails 4 and 5. The filter inspection system 1 conveys the work 2 inspected by the inspection device 7 along rails 4 and 5 to a holding device, for example, a discharge device 8 for the work 2. The filter inspection system 1 discharges the work 2 in different directions by the discharge device 8 according to the inspection result of the inspection device 7 and sorts the work 2 into a good product and a defective product.
The filter inspection system displays an inspection state on a monitor 9 arranged adjacent to the base 3.

The work 2 is made of plastic material,
Since it is used as a filter for filtering air, it is integrally injection molded into a substantially rectangular flat plate shape. As shown in FIG. 2, the work 2 has a peripheral portion formed by a thick frame 10 having a width of 5 to 7 [mm], for example, and is divided by the thick frame 10 in the longitudinal direction and the width direction, respectively. , 9 blocks 11
It is divided into ~ 19. Further, the work 2 has reinforcing ribs 22 near the periphery of the back surface except for the short sides 20 and 21 central portions.

Has a semicircular cross section and is formed in the width direction of the work 2.

The work 2 tends to be recessed at the central portion in the longitudinal direction where the reinforcing ribs 22 and 23 are not arranged. Therefore, as shown in FIG. 6, the lattice 28 on the back side is warped, and the directions of the V-shaped tips of the lattice 27 on the front side are not aligned. When the work 2 is illuminated from below in this state, the illumination light 29 emits the illumination light 29 on the front side.
The light is reflected in different directions on the side surfaces, and the amount of light becomes uneven at the edge portion of the grating 27 on the front side, as indicated by the diagonal lines in FIG. Therefore, there is a possibility that the aperture ratio cannot be measured correctly and that the threshold level for binarization cannot be set to an arbitrary value. Therefore, it is necessary to make the work 2 flat so that the transmission image of the work 2 can always be captured stably.

As shown in FIG. 8, the supply device 6 is provided with peripheral mounting means for mounting the work 2, for example, a rectangular inspection frame 30. On the base 3 below the frame 30, a central part mounting means for moving up and down, for example, a work receiving base 31.

A rotary actuator 43 is arranged on each positioning plate 38, and the work 2 is clamped and held by a holding means, for example, a clamper 44, which is connected to the rotary shaft of the rotary actuator 43.

The work receiving base 31 is moved up and down by a cylinder 45 with a detent to a rectangular opening formed on the inner peripheral surface of the frame body 30, and when the work 2 is set, rises to the rising end. The work cradle 31 can be adjusted so that the height of the upper surface when the work pedestal 31 is raised to the rising end is substantially the same as the upper surfaces of the positioning plates 37 and 38.

The lifter 32 lifts and lowers the box-shaped lift base 47 by the lift unit 46. Lifting base 47
A pair of long plate-shaped claws 48 for receiving the work 2 are fixed on the top. A portion 49 of the claw 48 that receives the work 2 is made of a thin and strong material, and when it descends, it stops in the gap between the work receiving base 31 and the frame body 30. The claw 48 clamps the workpiece 2 on the positioning plates 37 and 38 on the frame 30,
After the frame body 30 moves, it rises again.

In the work guide portion 33, a pair of overhanging length adjusting rods 51 are inserted into a square bar-shaped base 50, and work guides 52 and 53 are provided at the tip of the length adjusting rods 51 to form the mold member 5.
It is installed through 4. Work guides 52 and 53

The inspection device 7 detects whether the mesh is missing or clogged according to the detected opening area of the mesh, calculates the number of each, and determines the quality of the work 2 based on the reference data of the non-defective work 2. The inspection device 7 processes the calculation result and displays it on the monitor 9 or stores it in a memory (not shown).

As shown in FIG. 9, in the ejecting device 8, an elevating and rotating cylinder 59 is arranged on the base 3 between the rails 4 and 5. An elevating / lowering cylinder 59 is provided with an elevating / lowering bar 60 penetrating from the upper part to the lower part, and an elevating / lowering means, for example, a rectangular plate-shaped elevating / lowering table 61 is horizontally fixed to the upper end of the elevating / lowering bar 60. . Lifting rotation cylinder 59
Causes the lifting / lowering rotary table 61 to be lifted to transfer the work 2 from the frame 30, and the lifting / lowering rotary table 61 is rotated 90 ° in the horizontal plane according to the inspection result given by the inspection device 7.

A bearing 62 having a substantially U-shaped groove in the direction of the longitudinal direction of the lifting / lowering table 61 is provided near one short side of the lifting / lowering table 61. In the bearing 62, a plate-shaped bearing 63 is fitted in a substantially U-shaped groove, and a shaft 64 is horizontally inserted in common with the bearing 63 to pivot a mounting means, for example, a rectangular work receiving plate 65. I support you.

In the work receiving plate 65, the upper end of the bearing 63 is fixed near one short side of the lower surface. Work support plate 6
No. 5 is made of a material that is light and has a small friction coefficient, and the central portion 66 of the upper surface is formed to have a concave sectional shape. Work support plate 65
Is a cylinder 67 arranged on the lifting / lowering rotation table 61.
It is pushed up by and is tilted with respect to the up-and-down rotation table 61. As a result, when the work 2 whose long side is bent upward is placed on the work receiving plate 65 and tilted, the work receiving plate 65
Can be slid and discharged in a stable posture along the longitudinal direction of the central portion 66.

A work receiving plate 65 is provided near the center of both short sides of the elevating and rotating table 61 with a work receiving plate 65, for example, a mesh inserting means having wire rods, for example, bristles 68 planted at the upper end thereof, for example, a pair of detent brushes 69. In addition, they are arranged apart from the work receiving plate 65 by a predetermined distance. The whirl-stop brush 69 has, for example, a brush rod 70 disposed on the lower side, and the lower end thereof is fitted and inserted into the elevating and rotating table 61. The relative height between the bristles 68 and the work receiving plate 65 of the whirl-stop brush 69 is adjusted by a screw 71 that fixes the brush rod 70. This relative height is set so that the upper end of the bristles 68 is always higher than the upper surface of the work receiving plate 65.

As shown in FIG. 10, the non-rotating brush 69
A plurality of bristles 68 are planted in an annular shape on the edge of the upper end surface of the brush rod 70. The bristles 68 are made of a strong material that does not damage the work 2, for example, hard Teflon. As shown in FIG. 11, the bristles 68 have a thickness that allows one or more bristles to be inserted into the mesh openings 26 of the work 2, and are formed in a hemispherical shape with a substantially smooth tip. Further, the bristles 68 are regulated so as to be inclined outward from the center of the upper end surface of the brush rod 70 by a mushroom-shaped brush retainer 72. The brush holder 72 is fixed to the upper end surface of the brush rod 70 with a screw 73.

As shown in FIG. 1, on the rail 5 side of the work receiving plate 65, there is provided a shutter 74 with its tip facing downward. On the end side of the rails 4 and 5 of the work receiving plate 65, a shutter 75 with its tip facing downward is disposed. The shutter 74 drops the inspected work 2 discharged by the work receiving plate 65 onto the belt conveyor 76 as a good product. The work receiving plate 65 drops the tested work 2 discharged by the work receiving plate 65 into the defective product storage box 77.

In the above-described structure, the filter inspection system 1 operates according to the work processing procedure shown in FIG.
Are classified into good products and defective products. That is, the filter inspection system 1 enters from the start step SP0 and goes to step S
At P1, when the work 2 having the front side facing downward is supplied onto the claw 48, the process proceeds to step SP2. Step SP
In 2, the filter inspection system 1 lowers the claw 48, guides the work 2 by the work guides 52 and 53, and temporarily waits on the claw 48. After that, when the frame body 30 returns to the original position, the filter inspection system 1 raises the work receiving base 31 to the rising end.

Subsequently, the filter inspection system 1 is provided with the nail 4
8 is lowered and stopped near the frame body 30. As a result, as shown in FIG. 13 (A), the work 2 bent upward is bent.
Is placed on the work pedestal 31 at the center. Assuming that the warp amount of the work 2 at this time is d ₀ , a work having a width of 250 [mm] was d ₀ = 10 [mm]. When the work 2 is placed on the work cradle 31 in this manner, the filter inspection system 1 moves to step SP3.

At step SP3, as shown in FIG. 13 (B), the filter inspection system 1 regulates the height of the central portion of the work 2 to the height of the rising end of the work receiving base 31, and the work 2 The four corners are clamped simultaneously by clampers 42 and 44. As a result, the work 2 is warped so that the height of the center portion is the same as the heights of the four corners, the posture is corrected to be substantially flat, and the work 2 is positioned and held on the frame body 30. After that, as shown in FIG. 13C, the work cradle 31 is lowered, and the work 2 is held on the frame body 30 while maintaining a substantially flat state. Assuming that the amount of warpage of the work 2 at this time is d ₂ , the work 2 having a width of 250 [mm] was d ₂ = 2 [mm] or less.

Incidentally, in the case where the work holder 31 is not provided, as shown in FIG. 14A, the work 2 is transferred directly from the claw 48 onto the positioning plates 37 and 38. Then, in FIG.
As shown in (B), the work 2 includes clampers 42 and 4
It is clamped by 4 and held. Assuming that the warp amount of the work 2 at this time is d ₁ , a work having a width of 250 [mm]
d ₁ ≒ Atsuta at 8 [mm].

In this way, the warp of the work 2 can be further reduced and held on the frame 30 with a simple structure. When the work 2 is held on the frame 30, the filter inspection system 1 moves to step SP4. Step SP
In 4, the filter inspection system 1 moves the work 2 held on the frame 30 to the inspection device 7 along the rails 4 and 5, and moves to step SP5.

In step SP5, the filter inspection system 1 inspects the shape of the work 2 by the inspection device 7.
At this time, since the posture of the work 2 is corrected to be substantially flat, the filter inspection system 1 can more stably image the mesh of the whole work 2 within the focal depths of the first to fourth cameras 55 to 58. You can In step SP5, if the quality is determined and a positive result is obtained, the filter inspection system 1 determines that the work 2 is a good product and moves to step SP6. In step SP6, the filter inspection system 1 conveys the work 2 inspected on the frame 30 to the discharging device 8 and stops it, and releases the clampers 42 and 44.

Subsequently, in the filter inspection system 1, the lifting / lowering rotary table 61 is lifted by the lifting / lowering rotary cylinder 59 to transfer the work 2 to the work receiving plate 65. At this time, as shown in FIG. 11, the tip of the bristle 68 of the rotation preventing brush 69 positioned slightly above the upper surface of the work receiving plate 65 is inserted into the mesh opening 26 of the work 2. As a result, the work 2 is held stationary in a state of being entwined with the bristles 68, and is held on the work receiving plate 65 without being displaced.

After that, the filter inspection system 1 tilts the work receiving plate 65 by the cylinder 67. At this time, the tip of the bristles 68 of the whirl-stop brush 69 is removed from the mesh opening 26 of the work 2 as the inclination angle of the work receiving plate 65 increases. As a result, the work 2 can be discharged to the shutter 74 without being blocked by the hair transplant 68. When the work 2 is discharged, the filter inspection system 1
Moves to step SP7 and ends the processing of one work 2. The workpiece 2 slides on the shutter 74, and the conveyor 7
6 is dropped onto 6 and is carried out as a non-defective product in the next process.

On the other hand, if a negative result is obtained in step SP5, the filter inspection system 1 judges that the work 2 is a defective product and moves to step SP8. Step SP
8, the filter inspection system 1 conveys the inspected work 2 to the discharging device 8 and stops it, and the work receiving plate 6
Reprinted in 5. After that, in the filter inspection system 1, the work receiving plate 65 is rotated 90 ° clockwise by the lifting / lowering rotation cylinder 59. At this time, the work 2 rotates without being displaced from the work receiving plate 65 because the holding force in the in-plane direction in the state where the bristles 68 are entangled is larger than the inertial force during the rotation.

After changing the direction of the workpiece 2, the filter inspection system 1 moves to step SP9. Step SP
At 9, the filter inspection system 1 tilts the work receiving plate 65. At this time as well, the work 2
Can discharge the work 2 to the shutter 74 without being blocked by the hair transplant 68. When the work 2 is discharged, the filter inspection system 1 moves to step SP7 and finishes the processing of one work 2. The work 2 falls in the storage box 77 as a defective product. In this way, the filter inspection system 1
The work 2 can be sorted into a good product and a defective product with a simple configuration.

According to the above configuration, the frame body 30 and the frame body 3
Clampers 42 and 44 for clamping the peripheral part of the work 2 on 0, and a positioning plate on the frame 30 for raising the height of the central part of the work 2 before rising to the rectangular opening of the frame 30 to clamp the peripheral part. By disposing the work pedestal 31 that is regulated to be substantially the same height as 37 and 38, the warp of the work 2 can be corrected and held on the frame body 30. Therefore, the inspection accuracy of the held work 2 can be improved.

Further, an inclined work receiving plate 65 and a rotation preventing brush 69 for inserting the tip end of the bristle 68 into the mesh opening of the work 2 when the work 2 is placed on the work receiving plate 65.
Lifting and turning table 6 which is held so that it can be lifted and lowered and rotated.
By disposing the work piece 1 on the work piece 1, the work piece 2 can be prevented from slipping due to inertia when the work piece 2 is rotated.
