Therefore, a device for adsorbing and conveying the upper surface of the object to be conveyed is used. As shown in FIG. 5, this device adsorbs an object to be conveyed 11 surrounded by a packaging film 10 by an adsorbing device 12 and conveys it, and the inside of the cup-shaped adsorbing device 12 by a vacuum pump (not shown). The object to be conveyed is lifted by depressurizing and sucking the packaging film 10.

を提供することを技術的課題とする。However, since the pressure is reduced in the portion in contact with the suction device, it is inevitable that the portion expands and deforms like a dome. Therefore, in the above-mentioned conventional one, there is no problem when the transported object is lightweight, but when the transported object is a heavy object, the packaging film cannot withstand the weight of the transported object and is destroyed. There is a risk that objects will fall. In this case, if the packaging film is made thick, it can handle a certain amount of weight, but deformation of the suction surface is unavoidable, and there is always a risk of falling. The present invention has been made in view of the above-mentioned matters, and an object thereof is to provide an adsorption / conveyance device capable of adsorbing and conveying a heavy object to be conveyed regardless of the strength of a packaging film.

That is, a cut portion for air circulation is formed on the suction surface of the packaging film, and when the suction surface of the packaging film is sucked, the transported object is sucked while sucking the air in the packaging film from the cut portion. The technical means is configured as described above. The cut portion may be formed by cutting the packaging film into a curved shape, for example, a semicircular shape. Further, the suction device has a suction port, and if a flexible material such as sponge rubber is provided on the edge of the suction port, the packaging film will not be damaged. Further, if a net is installed inside the suction port, excessive suction of the packaging film is suppressed.

され包装フィルムを傷める虞れがない。When the object to be conveyed is conveyed, the adsorption device is adsorbed on the adsorption surface to reduce the pressure inside the adsorption device. Then, the air in the packaging film is sucked from the cut portion and the transported object is adsorbed. In this state, the suction device is moved vertically or horizontally and conveyed to a desired position. In this way, the suction force of the suction device is received not by a specific portion but by the entire transported object, so that if the upper surface of the transported object is smooth, the weight of the transported object itself up to the suction strength limit can be reduced. Can be lifted. The shape, size and number of the cut portions are not particularly limited as long as the air is not accumulated in the adsorption portion and the air can be released uniformly, but the shape thereof is preferably
If it is formed by cutting in a curved shape, for example, a semicircular shape, the flow of air will be extremely smooth, the load on the packaging film in a depressurized state can be minimized, and it will be in a substantially sealed state in a state other than conveyance, so that it will be covered. It is possible to prevent damage and stains on conveyed items. Further, if a flexible material such as sponge rubber is provided on the edge of the suction port of the suction device, the packaging film will not be damaged. Furthermore, a net is installed inside the suction port,
Moreover, by appropriately adjusting the position of the net body from the edge of the suction device, deformation of the packaging film due to excessive suction is suppressed and there is no risk of damaging the packaging film.

き、安定した吸着搬送が可能となった。Embodiments of the present invention will be described with reference to FIGS. The transported object 2 is EPDM which is a kind of synthetic rubber.
(Ethylene / Propylene / Non-conjugated diene copolymer rubber)
This is a so-called EPDM veil obtained by press-molding pellets, and is molded into a size of about 36 cm × 72 cm × 50 to 200 cm, and the weight is 10 to 35 kg. This transported object 2 is surrounded by a packaging film 1, and the periphery is sealed by heat sealing. This packaging film 1
Is made of polyethylene film and has a thickness of 35 to 100 μm. As described above, the central portion of the upper surface of the packaging film 1 that surrounds the transported object 2 is the suction surface 4, and the cut portion 5 is formed within the range of the suction surface 4. As shown in FIG. 3, the cut portion 5 has a semicircular shape along a circle having a diameter of 6 mm, and is provided at a total of 6 positions. The load having the above configuration is adsorbed by the adsorption device 3 and conveyed. The suction device 3 is provided at the tip of an arm of an industrial robot (not shown), is formed in a substantially cup shape, and has an air suction hole 3a formed in its bottom plate.
The air suction hole 3a is connected to a vacuum pump (not shown). A flexible material 7 made of an annular sponge rubber is provided on the edge of the suction device 3. The flexible material 7 prevents the packaging film from being scratched, and can prevent air leakage even if the top surface of the transported object 2 has some irregularities. A mesh 8 is installed inside the suction port. This net body 8 has an air suction hole 3a.
Is to prevent the film from being deformed, and its mounting position is set at a height of 25 mm from the lower edge of the flexible material 7. When the object to be conveyed 2 is conveyed, the adsorption device 3 is adsorbed on the adsorption surface 4, and the pressure in the adsorption device 3 is set to -300 to -400 mmHg. Then, the air in the packaging film 1 is sucked from the cut portion 5 and the transported object is sucked. In this state, the suction device 3 is moved vertically or horizontally to convey it to a desired position. In this case, no substantial force is applied to the packaging film 1 and it is not damaged. As shown in FIG. 4, the suction device is configured by providing a large capacity first valve A and second valve B in the middle of a pipe connecting the vacuum pump P and the adsorption device 3. The second valve B has a small capacity and can control the opening degree with high accuracy. When sucking with this device, first, the second valve B is first opened to reduce the pressure inside the adsorption device 3 to a predetermined pressure, and then the first valve is opened. As a result, the suction time etc. can be adjusted freely regardless of the shape and weight of the transported object, and stable suction transportation becomes possible.
