Description
本発明は、負圧を利用して物体表面に吸着する負圧吸着盤において、スレート屋根材のような、波形の襞を備えた表面形状を備える物体表面へも負圧吸着することが可能な負圧吸着盤に関する。 The present invention relates to a negative pressure suction cup that uses negative pressure to adhere to the surface of an object, and is capable of negative pressure adhesion to the surface of an object with a surface shape that has corrugated pleats, such as slate roofing materials.
従来、負圧を利用して物体表面に吸着する負圧吸着盤の構成について；
物体表面に対面する面が開口している、立体形状の吸着盤函体と；
前記の吸着盤函体の前記の開口している面を規定している吸着盤内枠に装着されており、且つ、前記の吸着盤内枠に装着された内縁の部分すなわちシール内縁部を備えており、前記のシール内縁部から外側に伸びた部分すなわちシール本体部を備えており、且つ、伸びきった外縁の部分すなわちシール外縁部を備えている吸着盤シール；から構成されている。
従来の負圧吸着盤において、スレート屋根材のような、波形の襞を備えた表面形状を備える物体表面へ負圧吸着することが可能な負圧吸着盤に関する技術としては、吸着盤シールの素材としてゴムスポンジを使用した負圧吸着盤が公知である。
Conventionally, the configuration of a negative pressure suction cup that uses negative pressure to adhere to the surface of an object has been described as follows:
a three-dimensional suction cup box having an open surface facing the object surface;
a suction cup seal attached to an inner suction cup frame defining the open face of the suction cup box, the suction cup seal having an inner edge portion or seal inner edge portion attached to the inner suction cup frame, an extending portion or seal body portion extending outward from the inner seal edge portion, and an extending outer edge portion or seal outer edge portion.
Among conventional negative pressure suction cups, a known technology for negative pressure suction cups that can be negatively suctioned onto the surface of an object with a corrugated surface shape, such as slate roofing materials, is a negative pressure suction cup that uses rubber sponge as the material for the suction cup seal.
吸着盤シールの素材としてゴムスポンジを使用した負圧吸着盤においては、吸着盤シールの体積が大きく、且つ、機械的強度が弱く、且つ、耐摩耗性に乏しい、という欠点がある。 Negative pressure suction cups that use rubber sponge as the suction cup seal material have the disadvantages of a large suction cup seal volume, weak mechanical strength, and poor abrasion resistance.
以下、上記の課題を達成するための手段を説明する。
上記の課題を達成するために、本発明によれば、吸着盤シールの素材として、体積が大きくなるなどの欠点を有するゴムスポンジを使用せず、膜状の素材を使用することを提案している。
吸着盤シールの素材を膜状の素材とすれば、耐摩耗性が大きいポリウレタンシートや、アラミド繊維など高強度の繊維から成る織布を、ゴムスポンジの代わりに吸着盤シールの素材として使用できるので、上記のゴムスポンジに係る課題を達成することが可能となる。
一方、吸着盤シールに要求される更なる機能について、物体表面が例えばスレート屋根材のような波形の襞を備えた表面形状を備える場合、吸着盤シールは、スレート屋根材の形状に倣って変形できる機能を有していることが重要である。なお、ゴムスポンジは、スレート屋根材の形状に倣って変形できる機能、を備えている。
吸着盤シールの素材を膜状の素材とした場合において、物体表面の形状に倣って変形できる機能、に係る問題点として、例えば、ポリウレタンシートの硬度を例えば硬度が３０度まで小さくすれば伸縮性が増大するので、而して、スレート屋根材の形状に倣って変形できる機能、を備えることになるが、一方で、伸縮性の増大に起因して機械的強度が弱くなる。
よって、吸着盤シールの素材を、例えば、ポリウレタンシートとする場合においては、機械的強度を大きくするために、ポリウレタンシートの硬度を小さくすることを諦め、すなわち伸縮性を犠牲にする必要がある。
なお、吸着盤シールの素材をアラミド繊維から成る織布とする場合においては、伸縮性が無いので、スレート屋根材の形状に倣って変形できる機能、を備えることは無い。
而して、素材が膜状である吸着盤シールがスレート屋根材の形状に倣って変形できる機能、を備えるために、すなわち本発明の課題を達成するための手段として、本発明においては、例えば、下記の負圧吸着盤が提供される。
すなわち、
物体表面に対面する面が開口している、立体形状の吸着盤函体と；
前記の吸着盤函体の外周部分に具備された吸着盤外枠と；
前記の吸着盤函体の前記の開口している面を規定している吸着盤内枠に装着されており、且つ、前記の吸着盤内枠に装着された内縁の部分すなわちシール内縁部を備えており、前記のシール内縁部から外側に伸びた部分すなわちシール本体部を備えており、且つ、伸びきった外縁の部分すなわちシール外縁部を備えている、膜状の吸着盤シールと；
前記の吸着盤外枠に前記のシール外縁部が装着されている、負圧を利用して物体表面に吸着する負圧吸着盤において；
物体表面が例えば波形スレート屋根材である場合において、波の軸線と交差する方向に伸びている前記のシール内縁部の断面形状は、言い換えれば、前記のシール内縁部の切断面が波の軸線と交差する方向に伸びた面であって且つ物体表面と交差する面である断面形状は、前記のシール内縁部は波形の襞を備えた断面形状を備えており；
波の軸線と交差する方向に伸びている前記のシール外縁部の断面形状は、言い換えれば、前記のシール外縁部の切断面が波の軸線と交差する方向に伸びた面であって且つ物体表面と交差する面である断面形状は、前記のシール外縁部は波形の襞を備えた断面形状を備えている；
ことを特徴とする、負圧吸着盤、が提供される。
The means for achieving the above object will be described below.
In order to achieve the above object, the present invention proposes to use a film-like material as the material for the suction cup seal, rather than using rubber sponge, which has drawbacks such as being large in volume.
If the suction cup seal is made of a film-like material, a polyurethane sheet with high abrasion resistance or a woven fabric made of high-strength fibers such as aramid fiber can be used as the suction cup seal material instead of rubber sponge, making it possible to achieve the above-mentioned problems associated with rubber sponge.
On the other hand, when the surface of an object has a corrugated surface shape, such as a slate roofing material, it is important that the suction cup seal has the ability to deform to conform to the shape of the slate roofing material. Note that rubber sponge has the ability to deform to conform to the shape of the slate roofing material.
When the suction cup seal is made of a film-like material, there is a problem with the ability to deform to follow the shape of the surface of an object. For example, if the hardness of the polyurethane sheet is reduced to, for example, 30 degrees, the flexibility increases, and therefore the seal has the ability to deform to follow the shape of the slate roofing material. However, on the other hand, the increased flexibility weakens the mechanical strength.
Therefore, when the material of the suction cup seal is, for example, a polyurethane sheet, in order to increase the mechanical strength, it is necessary to give up on reducing the hardness of the polyurethane sheet, i.e., to sacrifice elasticity.
Furthermore, if the material of the suction cup seal is a woven fabric made of aramid fiber, it has no elasticity and therefore does not have the ability to deform to fit the shape of the slate roofing material.
Therefore, in order to provide a suction cup seal made of a membrane-like material with the ability to deform to conform to the shape of the slate roofing material, i.e., as a means for achieving the object of the present invention, the present invention provides, for example, the following negative pressure suction cup.
That is,
a three-dimensional suction cup box having an open surface facing the object surface;
an outer suction cup frame provided on the outer periphery of the suction cup box;
a membrane-like suction cup seal attached to an inner suction cup frame defining the open face of the suction cup box, the membrane-like suction cup seal having an inner edge portion attached to the inner suction cup frame, an outer edge portion extending outward from the inner edge portion, and an outer edge portion extending outward from the inner edge portion;
A negative pressure suction cup that uses negative pressure to adhere to the surface of an object, wherein the outer edge of the seal is attached to the outer frame of the suction cup;
In the case where the surface of the object is, for example, a corrugated slate roofing material, the cross-sectional shape of the inner edge of the seal extending in a direction intersecting with the axis of the waves, in other words, the cross-sectional shape of the cut surface of the inner edge of the seal extending in a direction intersecting with the axis of the waves and intersecting with the surface of the object, is such that the inner edge of the seal has a cross-sectional shape with corrugated pleats;
The cross-sectional shape of the outer edge of the seal extending in a direction intersecting the wave axis, in other words, the cross-sectional shape of the cut surface of the outer edge of the seal being a plane extending in a direction intersecting the wave axis and intersecting with the surface of the object, the outer edge of the seal has a cross-sectional shape with wave-like folds;
A negative pressure suction cup is provided.
本発明においては、負圧を利用して物体表面に吸着する負圧吸着盤において、スレート屋根材のような、波形の襞を備えた表面形状を備える物体表面へも負圧吸着することが可能であり、且つ、吸着盤シールは耐摩耗性と高強度を備えているので、耐久性に富み、且つ、高機能を有した負圧吸着盤が提供される。 In this invention, a negative pressure suction cup that uses negative pressure to adhere to the surface of an object can also be used to adhere to the surface of an object with a corrugated surface, such as slate roofing materials. Furthermore, the suction cup seal is abrasion-resistant and highly strong, providing a highly durable and highly functional negative pressure suction cup.

a three-dimensional suction cup box 21 having an open surface facing the object surface 1;
an outer suction cup frame 22 provided on the outer periphery of the suction cup box 21;

In the negative pressure suction cup 2, the seal outer edge portion 233 is attached to the suction cup outer frame 22, and the negative pressure suction cup 2 is attached to the surface 1 of an object by using negative pressure;
For example, in the case of an object surface 1 which is a corrugated slate roofing material, the cross-sectional shape of the seal inner edge portion 231 extending in a direction intersecting with the wave axis, in other words, the cross-sectional shape of the cut surface of the seal inner edge portion 231 which is a plane extending in a direction intersecting with the wave axis and intersecting with the object surface 1, the seal inner edge portion 231 has a cross-sectional shape with corrugated pleats;
The cross-sectional shape of the seal outer edge portion 233 extending in a direction intersecting the wave axis, in other words, the cross-sectional shape in which the cut surface of the seal outer edge portion 233 is a plane extending in a direction intersecting the wave axis and intersecting with the object surface 1, means that the seal outer edge portion 233 has a cross-sectional shape with wave-shaped folds.
The seal inner edge portion 231 is fixed to the suction cup inner frame 212 by a seal inner edge fastening member 213 and a seal inner edge fastening bolt 214 .
The seal outer edge portion 233 is fixed to the suction cup outer frame 22 by a seal outer edge fastening member 223 and a seal outer edge fastening bolt 224 .
In the first embodiment of the present invention, as shown in the top view of Figure 3, the shape of the upper surface of the seal outer edge portion 233, the shape of the upper surface of the suction cup outer frame 22, and the shape of the upper surface of the seal outer edge fastening member 223 are flat rather than wavy.
Although not shown in the top view of Figure 3, the shapes of the upper surfaces of the seal inner edge portion 231, the suction cup inner frame 212, and the seal inner edge fastening member 213 are flat rather than wavy.
A fluid coupling 211 is drilled into the suction cup box 21, and the fluid coupling 211 is connected to a vacuum pump (not shown) via a fluid hose (not shown).
吸着盤函体２１の外周部分に具備された吸着盤外枠２２について述べると、本発明の第１の実施例の吸着盤外枠２２は、吸着盤函体２１の外周部分を包囲している函体の形状であり、物体表面１に対面した部分が開口している。

Regarding the suction cup outer frame 22 provided on the outer periphery of the suction cup box 21, the suction cup outer frame 22 in the first embodiment of the present invention is in the form of a box that surrounds the outer periphery of the suction cup box 21, and the portion facing the object surface 1 is open.
A fluid coupling 221 is drilled into the suction cup outer frame 22, and the fluid coupling 221 is connected to a flow path switching valve (not shown) via a fluid hose (not shown). The flow path switching valve has a flow path configuration that can be selectively connected to a low-pressure air compressor (not shown) and a low-pressure vacuum pump (not shown).
The suction cup outer frame 22 in the first embodiment of the present invention comprises an airtight housing that surrounds the outer periphery of the suction cup housing 21, but the suction cup outer frame 22 does not necessarily have to comprise an airtight housing, and there may also be an embodiment in which the suction cup outer frame 22 comprises only a frame to which the seal outer edge portion 233 is fixed.
なお、図７の上面図に示す本発明の第２の実施例においては、シール外縁部２３３の上面の形状と、吸着盤外枠２２の上面の形状と、シール外縁部締付部材２２３の上面の形状とは、波形である。

In the second embodiment of the present invention shown in the top view of Figure 7, the shapes of the upper surfaces of the seal outer edge portion 233, the suction cup outer frame 22, and the seal outer edge fastening member 223 are all wavy.
Although not shown in the top view of Figure 7, the shape of the upper surface of the seal inner edge portion 231, the shape of the upper surface of the suction cup inner frame 212, and the shape of the upper surface of the seal inner edge portion tightening member 213 are wavy.
In the drawings of the second embodiment of the present invention, the plan view of FIG. 1, the right side view of FIG. 2, the cross-sectional view taken along line B-B of FIG. 5, and the rear view of FIG. 6 are common to the drawings of the first embodiment of the present invention.
For purposes of describing a second embodiment of the present invention, the inventors have described a second embodiment of the present invention for purposes of the following explanation.
That is, as shown in the top view of Figure 7, even if the shape of the upper surface of the seal outer edge portion 233, the shape of the upper surface of the suction cup outer frame 22, and the shape of the upper surface of the seal outer edge fastening member 223 are wavy rather than flat, there is no problem with the function and performance of the negative pressure suction cup.
Although not shown in the top view of Figure 7, the shape of the upper surface of the seal inner edge portion 231, the shape of the upper surface of the suction cup inner frame 212, and the shape of the upper surface of the seal inner edge fastening member 213 may be wavy rather than flat, without causing any inconvenience to the function and performance of the negative pressure suction cup.
以下に、上述した負圧吸着盤２の作用について説明する。
負圧吸着盤２の吸着盤シール２３が物体表面１に対面し接触している時に、吸着盤函体２１と吸着盤外枠２２と吸着盤シール２３とにより包囲された空間へ、流体継手２２１を介して、低圧エアコンプレッサ（図示しない）から、低圧の空気を流入させると、吸着盤シール２３は物体表面１の方向へ膨張する。
次に、真空ポンプ（図示しない）が動作すると、物体表面１と負圧吸着盤２を包囲している大気は、吸着盤函体２１に穿設されている流体継手２１１と流体ホース（図示しない）を経由して真空ポンプ（図示しない）に吸引されるので、吸着盤シール２３は物体表面１に密着し、すなわち、負圧吸着盤２は物体表面１へ負圧吸着する。
次に、低圧エアコンプレッサ（図示しない）から低圧真空ポンプ（図示しない）へ、前記の流路切換弁の流路が変更される。
なお、低圧エアコンプレッサ（図示しない）から低圧真空ポンプ（図示しない）へではなく、低圧エアコンプレッサ（図示しない）から大気との連通へ、前記の流路切換弁の流路が変更されても良い。
負圧吸着盤２が物体表面１へ負圧吸着している時、吸着盤シール２３は、スレート屋根材の形状に倣って変形しており、よって、吸着盤函体２１と吸着盤外枠２２と吸着盤シール２３とにより包囲された空間の圧力が、吸着盤函体２１の内部の圧力より高いことに起因して、吸着盤シール２３は物体表面１へ押付けられ、すなわち、吸着盤シール２３は物体表面１に気密に密着している。
The operation of the negative pressure suction cup 2 will now be described.
When the suction cup seal 23 of the negative pressure suction cup 2 faces and contacts the object surface 1, if low-pressure air is flowed from a low-pressure air compressor (not shown) via the fluid coupling 221 into the space enclosed by the suction cup box 21, the suction cup outer frame 22, and the suction cup seal 23, the suction cup seal 23 will expand toward the object surface 1.
Next, when the vacuum pump (not shown) is operated, the atmosphere surrounding the object surface 1 and the negative pressure suction cup 2 is sucked into the vacuum pump (not shown) via the fluid coupling 211 drilled into the suction cup box 21 and a fluid hose (not shown), causing the suction cup seal 23 to adhere tightly to the object surface 1, i.e., the negative pressure suction cup 2 is negatively pressure-adsorbed to the object surface 1.
Next, the flow path of the flow path switching valve is changed from the low-pressure air compressor (not shown) to the low-pressure vacuum pump (not shown).
The flow path of the flow path switching valve may be changed from a low-pressure air compressor (not shown) to communication with the atmosphere, rather than from a low-pressure air compressor (not shown) to a low-pressure vacuum pump (not shown).
When the negative pressure suction cup 2 is negatively pressure-sucked to the object surface 1, the suction cup seal 23 is deformed to follow the shape of the slate roofing material. Therefore, because the pressure in the space enclosed by the suction cup box 21, suction cup outer frame 22, and suction cup seal 23 is higher than the pressure inside the suction cup box 21, the suction cup seal 23 is pressed against the object surface 1, i.e., the suction cup seal 23 is airtightly adhered to the object surface 1.

以上に本発明の装置の好適実施例について説明したが、本発明の装置は前記の好適実施例の他にも特許請求の範囲に従って種々実施例を考えることができる。
なお、以上の本発明の装置の好適実施例についての説明は、本発明の装置が大気中の物体表面上に在るものとして説明を行ったが、本発明の装置は水中においても適用されることができる。かかる場合の負圧生成手段については、真空ポンプに代えて水ポンプや水駆動エゼクタを用いることができる。
