Patent number: 7258291Abstract: A destructive device, wherein treated material (1) including a foam body is pre-compressed in thickness direction and fed to the opposed part of a pair of compression rolls (21, 22), partition walls forming independent air bubbles in the foam body is destructed by the compression rolls (21, 22) and foam gas is arrested into a cover (3) installed on the outlet side of the compression rolls (21, 22), the foam gas is liquefied and separated by a cooling and liquefying device (6) through a cooling device (15) after pressurized, together with medium gas (41) for collection, by a pressurizing device (5), and the medium gas for collection from which the foam gas is separated is returned into the cover (3), whereby, since the foam gas is liquefied and separated in pressurized state by the cooling and liquefying device (6) by arresting the foam gas in high density inside the cover (3), the device can be remarkably downsized and simplified, and a device cost and an operation cost can also be remarkably reduced.Type: GrantFiled: January 22, 2003Date of Patent: August 21, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Yotsumoto, Yutaka Matsuda, Susumu Saitou, Masayuki Makino, Kazuo Kimura, Yasuo Sasaki

Patent number: 7134387Abstract: A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of equipment and an installation space.Type: GrantFiled: July 12, 2001Date of Patent: November 14, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Yotsumoto, Yutaka Matsuda, Takayuki Gyoubu, Katsuya Sawada

Patent number: 6938318Abstract: A method for disassembling a discarded refrigerator that uses a foamed resin as a heat insulator according to the present invention includes the processes of cutting and separating a heat-insulating housing of a refrigerator into pieces having a predetermined size and shape; obtaining the foamed resin by passing the pieces between a pair of compression rollers arranged so as to oppose each other and compressing the pieces, thereby peeling off and separating an incompressible plate-like object layered at least on one surface of the pieces; and collecting a foaming gas by passing the foamed resin (301) between a pair of compression rollers (331, 332) arranged so as to oppose each other and compressing the foamed resin, thereby allowing the foaming gas in the foamed resin to leak out. This makes it possible to collect a foaming gas in a heat insulator while maintaining a high concentration with small equipment at low cost.Type: GrantFiled: September 20, 2001Date of Patent: September 6, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Yotsumoto, Yutaka Matsuda

The heat exchanger is cut while a top layer of an impact portion being smashed. It is possible to disassemble an air conditioner efficiently using a cutting device having a simple configuration and a long lifetime.Type: GrantFiled: August 13, 2001Date of Patent: January 4, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Yotsumoto, Yutaka Matsuda, Takayuki Gyoubu, Katsuya Sawada

Publication number: 20030131707Abstract: First and second rotating units (110, 120) include a pair of rotors (111, 121) opposing each other, a spindle (113, 123) provided between the pair of rotors, and an impacting body (130, 140) mounted rotatably on the spindle (113, 123). The impacting body (130, 140) is mounted so that a predetermined fitting gap is provided between the impacting body and the spindle and a part of a periphery of the impacting body can be positioned beyond a periphery of the rotor. The impacting bodies of the first and second rotating units impact on an object to be processed sequentially while the rotating units are rotated at a high speed, thereby cutting the object to be processed. A cutting depth by the impacting body of the second rotating unit is larger than that by the impacting body of the first rotating unit, and the impacting body of at least one of the rotating units impacts on the object to be processed at least at a critical impact velocity.Type: ApplicationFiled: August 13, 2002Publication date: July 17, 2003Inventors: Mikio Yotsumoto, Yutaka Matsuda
