DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handling apparatus suitable for a work for mounting a double-glazed frame.

[0002]

2. Description of the Related Art FIG. 14 is a sectional view of a double glazing having a sash.
01 and 102 are arranged with a gap therebetween, dry air is sealed in the gap, and a resin or metal spacer 10 is provided around the gap.
3 and excellent in sound insulation and heat insulation.

In recent years, the double-glazing unit 100 has come to be used for a glass door in a living room as part of improvement of housing equipment. The glass door 105 is attached to the double glazing 100 via a packing 106 called a bead.
For example, a sash 108 is provided with a door wheel 109. In addition, a sash means a window frame and a frame of a glass door, and is also called a sash.

Generally, a glass door 105 is a rectangular plate of 0.9 mx 1.8 m having the same size as a tatami mat.
It has a weight of 40 to 50 kg. A conventional single-pane glass door with a sash attached to only one piece of glass weighs 20 to 25 kg.

[0005] On the other hand, it is said that the weight that can be carried by one worker is 30 kg.
The sash mounting work is easy, but the double-layered glass door is too heavy to work by one person, and requires two people.

FIG. 15 is a view showing an example of a conventional sash mounting operation.
With the sheets loaded, send them to the sash installation work site. At the sash installation work site, one piece of double-glazed glass 100 is taken out of the double-glazed glass carrier 111, and the work table 11
3 and the packings 106 and 106 are put on the double glazing 100 on the work table 113, and then the sashes 107 and 1 are placed.
08 to complete the glass door 105. Then, the glass door 105 is moved to the glass door carrier 1 in the manner indicated by an arrow.
Place on 15. Reference numeral 116 denotes a fence, which can be inserted into and removed from the glass door carrier 115, and is set in front of the glass door 105 every time the glass door 105 is leaned. It is of the form.

[0007]

As indicated by the arrow or the arrow, the vertically placed double glazing 100 is placed horizontally, and the horizontally oriented glass door 105 is placed vertically, that is, the work is rotated by 90 °. Burden on the elderly. This is because the sash mounting operation is performed in a horizontal position, while the transport is performed in a vertical position to prevent breakage of the glass.

[0008] If the arrow ~ is called a handling operation,
This handling operation can be performed by a robot. However, since the sash mounting operation is generally performed in a home glass shop or the like, it is impossible to introduce an expensive robot. Therefore, the object of the present invention is to
It is an object of the present invention to provide an inexpensive handling device which can easily carry a plate-shaped body exceeding the above-mentioned conditions, such as carrying or changing the posture, by one person.

[0009]

In order to solve the above-mentioned problems, a first aspect of the present invention is a lift frame attached to a lateral moving means such as a bogie or a crane; an elevating plate attached to the lift frame so as to be able to move up and down; A swivel plate attached to a plate so as to be rotatable around a horizontal axis, and a pair of brackets attached to the swivel plate
And a first shaft rotatably mounted on the pair of brackets.
An L-shaped member extending from one end of the first shaft;
The first orthogonal to one axis and rotatably attached to the L-shaped member
A biaxial shaft, a suction cup supporting frame attached to the second shaft, a suction cup mounted to the suction cup supporting frame, a vacuum generator for bringing the suction cup into a suction state, and an elevating device for elevating the elevating plate along the lifting frame A plate-like body handling device comprising:
When the plate is inclined with respect to the vertical line, the first
Tilting the suction cup support frame about the axis or the second axis
It is characterized in that it is configured to be able to .

A vertically oriented plate-like body is sucked by a suction cup and rises,
By rotating around the horizontal axis as needed, sash installation and other operations can be performed.
Can be handled by humans. If the plate is a sheet glass,
Since it is possible to carry in, work, and carry out the sheet glass while standing upright, the work area can be small and the posture of the work does not change, so that the work efficiency is improved.

According to a second aspect of the present invention, the lifting means is an air cylinder. The air cylinder can absorb an impact force by an air cushion effect. When attaching the sash to the plate, the sash must be driven hard,
Since this impact force is sufficiently absorbed, there is no danger of damaging the handling device and no danger of damaging the plate-like body.

A third aspect of the present invention is characterized in that the vacuum generator is mounted on a suction cup supporting frame, and the ejector type vacuum generator generates a vacuum by blowing compressed air.
Since the vacuum generator is mounted on the suction cup support frame, the distance to the suction cup is extremely short, and the vacuum hose can be shortened. When the vacuum generator is placed outside the handling device, it is necessary to route a thick and long vacuum hose, but this is not necessary because the vacuum generator is mounted on the handling device. In addition, since the ejector type vacuum generator operates only with compressed air, it is only necessary to branch the compressed air supplied to the air cylinder as the lifting / lowering means, eliminating the need for electrical wiring work, simplifying the equipment and reducing equipment costs. Can also be reduced.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings should be viewed in the direction of reference numerals. FIG. 1 is a front view of a plate-shaped body handling apparatus according to the present invention.
A gate-shaped or mouth-shaped lift frame 2, guide rods 3, 3 erected on the lift frame 2,
A lifting plate 4 that moves up and down while being guided by 3;
Rotary drum 5 mounted to be rotatable about a horizontal axis
And a revolving plate 6 attached to the rotary drum 5, a suction cup supporting frame 8 attached to the revolving plate 6 via a frame swinging mechanism 30 (details will be described later), and 5 attached to the suction cup supporting frame 8.
Are composed of individual suction cups 9. These suction cups 9 are vacuum cups.

The suction cup supporting frame 8 includes left and right vertical frames 8a, 8b,
It is composed of intermediate frames 8c and 8d, upper and lower horizontal frames 8e and 8f, and other reinforcing materials. However, since the suction cup support frame 8 is pivotable, the terms left, right, up and down are names for convenience.

FIG. 2 is a side view of the plate-like body handling apparatus according to the present invention.
3 (for example, a truck 13 provided with a small-diameter wheel 11 and a caster 12). Reference numeral 14 denotes a handle, which indicates that the operator can freely move the lift frame 2 horizontally by gripping and pushing and pulling the handle 14.

FIG. 3 is a rear view of the plate-like body handling apparatus according to the present invention, in which rodless air cylinders 15 as lifting means are arranged along the vertical frame of the lift frame 2, and cylinder attachments 16, Reference numeral 16 indicates that the lifting plate 4 is supported, and the lifting plate 4 is connected to the guide rods 3 via the slide blocks 17. By supplying or discharging compressed air to the rodless air cylinders 15, 15, the lifting plate 4 can be freely raised and lowered.

Further, a brake mechanism 20 is mounted on the rotary drum 5 mounted on the lift plate 4. The brake mechanism 20 includes, for example, the rotary drum 5 and the brake shoe 2.
1, 21; link plates 22, 22 for moving the brake shoes 21, 21; and a brake spring 24 for pulling the link plates 22, 22 toward the brake side. 23 and 23 are brake release cylinders.

By supplying compressed air to the brake release cylinders 23, 23, a brake release state is established, and the rotary drum 5 can be freely rotated. When the compressed air is discharged from the brake release cylinders 23, 23, the brake spring 24 strongly presses the brake shoes 21, 21 against the rotary drum 5, and the rotary drum 5 is stopped by the frictional force. The brake mechanism 20 is safe because it operates on the brake side even when the supply pressure to the brake release cylinders 23 becomes zero due to a power failure, compressor failure, or the like.

FIG. 4 is an exploded perspective view of the frame swing mechanism according to the present invention. The frame swing mechanism 30 includes brackets 31 attached to the revolving plate 6 and these brackets 31 3.
1, a first shaft 32, an L-shaped member 33 extending from one end of the first shaft 32, a tip (lower end) of the L-shaped member 33, and a second shaft 34 passed to the first shaft 32. Consists of The second axis 34 is orthogonal to the first axis 32. By joining the second shaft 34 to the intermediate frame 8 d of the suction cup support frame 8, the suction cup support frame 8 can be tilted around the first shaft 32 with respect to the revolving plate 6, and
The frame swing mechanism 30 can be tilted around the axis 34.

FIGS. 5 (a) and 5 (b) are rear views of the suction cup supporting frame according to the present invention, and are separately shown in FIGS. 5 (a) and 5 (b) for the sake of simplicity. (A) shows an arrangement of an ejector type vacuum generator 41, a first vacuum chamber 42, a vacuum on / off valve 43, and a second vacuum chamber 44. 45 and 46 are vacuum hoses and 47 and 47 are filters. (B) shows that the second vacuum chamber 44 and the suction cups 9 are connected by vacuum hoses 48.

As is clear from the drawing, the first vacuum chamber 42 and the second vacuum chamber 44 are formed in the horizontal frames 8e and 8f of the suction cup supporting frame 8. If the horizontal frames 8e and 8f are formed of square pipes or round pipes and the ends of the pipes are made airtight, a vacuum chamber can be easily formed in the strength member. That is,
Generally, this kind of vacuum chamber employs a spherical container, but when the spherical container is attached to the suction cup supporting frame 8, it becomes heavy and obstructive, and its appearance is poor. In this regard, according to the present embodiment, the weight does not become heavy, does not interfere, and the appearance does not deteriorate.

FIG. 6 is a vacuum system diagram for adsorption according to the present invention. When compressed air of 5 kg / cm ² is supplied through a rotary joint 51, if the on / off valve 52 is in communication, the compressed air will be edgy. It reaches the E compactors vacuum generator 41, blow through silencer 53. In this process, a vacuum is generated in the vacuum generator 41. Therefore, the first vacuum chamber 4
In No. 2, the degree of vacuum increases with time. The vacuum generator 4
The maximum value of the generated vacuum of 1 is -90 kPa (-indicates a negative pressure based on the atmospheric pressure. Others are the same). At this time, since the vacuum on / off valve 43 is open to the atmosphere, the second vacuum chamber 44 is at atmospheric pressure. When the degree of vacuum in the first vacuum chamber 42 reaches a predetermined value (for example, −60 kPa), the pilot valve 55 is switched through the pilot line 54.

FIG. 7 is an operation diagram of FIG. 6, in which the pilot line 55
, The on / off valve 52 is switched to the “closed” side, and the operation of the vacuum generator 41 is stopped. Therefore, when the second vacuum chamber 44 approaches atmospheric pressure than a predetermined pressure, the pilot valve 55 and O
Driving a vacuum generator 41 automatically under the action of turnoff valve 52, always maintain the first vacuum chamber 4 the second vacuum level. To perform the suction operation, the operator manually switches the manually operated valve 57. Then, the pressure reaches the vacuum on / off valve 43 through the pilot line 58, and the vacuum on / off valve 43 is switched as shown in the figure. Then, the second vacuum chamber 44 becomes the first vacuum chamber 4
2, and the plate-shaped body 60 can be sucked by the suction cups 9. If the manually operated valve 57 is further switched (see FIG. 6)
Adsorption can be eliminated.

What is important here is that only compressed air is used for control and that the first vacuum chamber 42 is interposed. Generally, this type of control uses a solenoid valve. However, the use of a solenoid valve naturally requires electric wiring work, and a long cable must be drawn out to the handling device for power supply. Further, when a step of cleaning the plate-like body with a volatile solvent is included, there is a risk of ignition. Since only compressed air is used in the present embodiment, electric wiring is unnecessary, there is no danger of ignition, and work can be performed with confidence even in a coating line or a cleaning line that handles a solvent.

When the second vacuum chamber 44 is directly pulled by the vacuum generator 41, if there is a trouble such as a failure of the compressor or a disengagement of the rotary joint, the plate-like body being adsorbed falls. On the other hand, in the present embodiment, the suction is performed using the first vacuum chamber 42 which is substantially independent of the vacuum generator 41. There is no worry that 60 will fall.

FIG. 8 is a layout view of the lock mechanism of the suction cup supporting frame according to the present invention, wherein the suction cup supporting frame 8 includes the first shaft 32 and the second shaft 32.
It is structured to be rotatable about a shaft 34. In this state, the suction cup supporting frame 8 is not stabilized. Therefore, a frame pushing tool 61 and a stopper 62 are provided on the intermediate frame 8c of the suction cup supporting frame 8. 9A and 9B are detailed views of the lock mechanism according to the present invention. (A) is a sectional view taken along line aa of FIG. 8. The frame pushing tool 61 is, for example, an eccentric cam. By turning the eccentric cam, the intermediate frame 8 c is pushed as shown by an arrow. (B)
FIG. 9 is a sectional view taken along the line bb of FIG. 8, and the stopper 62 includes, for example, a hook member 63 attached to the revolving plate 6 and a hook member 64 attached to the intermediate frame 8c. The movement of the frame 8c downward in the drawing is indicated by the hook member 6.
3, 64.

As a result, in FIG. 8, the suction cup supporting frame 8 is apparently a frame pushing tool 61, a stopper 62 and a first shaft 32.
Will be supported at three points with the right end 32a of the
Since the remaining point serves as a support even if the user tries to incline about the line connecting the two points, there is no concern that the suction cup support frame 8 swings in the front and back directions in the drawing.

The operation of the above-described plate-like body handling apparatus will now be described. FIGS. 10A and 10B are explanatory diagrams (first half) of the operation of the handling device according to the present invention.
In (a), the multi-layer glass 60 as a plate-like body placed on the multi-layer glass carrier 65 is taken. At this time, the suction cup support frame 8 is made to be able to swing, and the double glass 60 inclined about 5 ° is sucked by the suction cups 9..., And the double glass 60 is raised by a rodless air cylinder (not shown). In (b), the trolley 13 is pulled sideways to the work area, and the double glazing 60 is raised or lowered to a height at which work is easy. In the figure, the double-layer glass 60 is raised for convenience. At that position, packing 6 is placed around double-glazed glass 60.
Wrap 6 and drive in a sash 67.

FIGS. 11A and 11B are explanatory diagrams (second half) of the operation of the handling device according to the present invention. (A)
By rotating the suction cup supporting frame 8 in units of 90 °, each side of the double-glazed glass 60 can be ranked higher. In particular, the driving of the sash 67 is burdensome in the "upward operation", so that it can be changed to an easy "downward operation". (B)
Then, the completed glass door 68 is placed on the glass door carrier 69.

As is apparent from FIGS. 10 and 11, the mounting operation of the sash is performed with the double glazing 60 in the vertical position.
Therefore, the double-glazed glass 60 is characterized in that all of the loading → work → unloading remains vertical. As a result, the work area becomes smaller as compared with the case where the double glazing is made horizontal.

FIG. 12 is an operation diagram of the lifting / lowering means of the present invention. A rodless air cylinder as the lifting / lowering means is schematically shown by air cylinders 71 and 72, wires 73 and the attachment 16 for convenience. The sash 67 must be hammered with a hammer 74 (preferably a rubber hammer or a wooden hammer). The impact force can be absorbed by Eakussho emissions of air cylinders 71, 72. When the elevating means is a mechanical jack or an electric cylinder based on a screw or a ball screw, a spring or rubber must be separately provided for absorbing shock, but this is not necessary in this embodiment.

FIG. 13 is a view showing another embodiment of the handling device according to the present invention. In this handling device 1B, the lift frame 2 is suspended from a trolley type crane 76. The other configuration is the same as that of FIG. 2, and the description is omitted by using the reference numerals. The trolley type crane 76 is suitable for mass production because the transfer route is fixed. As described above, the lateral moving means for mounting the lift frame 2 of the present invention may be any of a trolley, an overhead conveyor, a forklift, and a crane. In short, any means for horizontally moving the lift frame 2 may be used.

The plate-shaped body may be any of laminated glass, ordinary plate glass, metal plate, resin plate, and wood plate, in addition to double-glazed glass.

In the first aspect, the lifting means may be any one of a hydraulic cylinder, an electric cylinder, a mechanical cylinder, a chain and a sprocket, in addition to the air cylinder. The vacuum generator may be a rotary pump type, a reciprocating pump type, or a plunger pump type vacuum pump using an electric motor as a drive source.

[0035]

According to the present invention, the following effects are exhibited by the above configuration. According to the first aspect, the work such as sash mounting can be performed by sucking the vertically oriented plate-like body with the suction cup, ascending, and rotating it about the horizontal axis as necessary. Can be handled by one person. At this time,
When the target plate is inclined with respect to the vertical line,
By tilting the board support frame, the suction cups
You can come. In addition, a state where the plate-shaped body is inclined
When lowering, the suction cup support frame may be inclined. If the plate-like body is a sheet glass, the work can be carried in, worked, and carried out while the plate glass is standing up, so that the work area can be small and the posture of the work does not change, thereby improving work efficiency.

According to the second aspect, the air cylinder can absorb an impact force by an air cushion action. When attaching the sash to the plate, the sash must be strongly driven in. However, since this impact force is sufficiently absorbed, there is no danger of damaging the handling device, and there is no fear of damaging the plate.

According to the third aspect, since the vacuum generator is mounted on the suction cup supporting frame, the distance to the suction cup becomes extremely short, and the vacuum hose can be shortened. When the vacuum generator is placed outside the handling device, it is necessary to route a thick and long vacuum hose, but this is not necessary because the vacuum generator is mounted on the handling device. In addition, since the ejector type vacuum generator operates only with compressed air, it is only necessary to branch the compressed air supplied to the air cylinder as the lifting / lowering means, eliminating the need for electrical wiring work, simplifying the equipment and reducing equipment costs. Can also be reduced.
