Patent number: 4899532Abstract: A residual roving clearing apparatus for clearing a residual roving remaining on a roving bobbin. The residual roving clearing apparatus comprises a bobbin holding device for rotatably holding a roving bobbin, a cutting device for cutting layers of coils of residual roving remaining on the roving bobbin held by the bobbin holding device, and a rotary brush device for clearing the residual roving from the roving bobbin. The residual roving clearing apparatus is capable of efficiently clearing the residual roving from the roving bobbin by cutting layers of coils of the residual roving along a cutting line parallel to the axis of the roving bobbin held by the bobbin holding device, and stripping off the cut layers of coils of the residual roving from the roving bobbin by the rotary brush of the rotary brush device.Type: GrantFiled: March 16, 1989Date of Patent: February 13, 1990Assignee: Murao Boki Kabushiki KaishaInventor: Hiroaki Sanno

Patent number: 4840124Abstract: The present invention relates to a system for transporting rove bobbins between a flyer frame and a spinning frame wherein transporting operation of rove bobbins can be assured for a long period of time. The system comprises a plurality of driving devices provided at fixed positions along a transport rail. A carrier for hanging rove bobbins thereon is smoothly moved along the transport rail by way of a mechanical engaging structure which establishes motion transmission between the carrier and a successive one of the driving devices.Type: GrantFiled: May 20, 1988Date of Patent: June 20, 1989Assignee: Murao Boki Kabushiki KaishaInventor: Fumio Tadashima

Patent number: 4770354Abstract: A cop magazine for use in association with an automatic winding apparatus the cop magazine including an open-topped cylindrical drum; a tube creel provided inside the cylindrical drum, the creel including cells adapted to house a plurality of cops individually; a rotating member for rotating the tube creel intermittently cop by cop; a suction cap provided at the top end of a suction pipe passed through the tube creel, the suction cap including a slit faced to the delivery-ready position and the delivery position in the tube creel; and a rotary blade for opening and closing the slit so as to release and retain the yarns, the rotary blade being operable in association with the rotation of the tube creel. This structure provides a cop magazine having a simplified construction whereby the yarn ends leading from the cops are retained under suction during movement of the cops from the magazine to the winder.Type: GrantFiled: April 1, 1987Date of Patent: September 13, 1988Assignee: Murao Boki Kabushiki KaishaInventor: Hiroaki Sanno

Patent number: 4765043Abstract: An apparatus for removing residual rovings on roving bobbins in a most efficient manner. A roving bobbin has an annular sticking cloth secured to a portion of the peripheral surface thereof for attaching of a wind-starting end of a roving wound around the roving bobbin. The roving bobbin is rotated in a direction in which the roving is wound around the roving bobbin. A jet of air is directed toward the sticking cloth substantially in a tangential direction thereof in such a manner as to oppose the rotation of the roving bobbin, thereby removing residual portions of the roving attached to the surface of the sticking cloth.Type: GrantFiled: October 16, 1986Date of Patent: August 23, 1988Assignee: Murao Boki Kabushiki KaishaInventor: Osamu Yamashita

Patent number: 4742967Abstract: A system for delivering packages wound by ring spinning frames to an automatic winder including cop magazines, wherein the leading yarn end of each package is caught and previously put into the top opening of the bobbin. The system includes a disposal machine for disposition of leading yarn end; a circulating conveyor line laid along the row of cop magazines, and provided with circulating trays for transporting packages from the disposal machine; and a transfer machine arranged so as to move along the row of cop magazines freely in opposite directions of travel on the conveyor line for transferring each package from one tray to any cop magazine as desired.Type: GrantFiled: January 12, 1987Date of Patent: May 10, 1988Assignee: Murao Boki Kabushiki KaishaInventors: Hiroaki Sanno, Takaharu Matsuoka, Kenji Katada

Patent number: 4667807Abstract: A bobbin feeding device includes a plurality of trays placed on a running belt under guidance of the side walls of the feeding device. Each tray includes a seat having a larger diameter than that of the bobbin, a bobbin supporting pin erected on the seat, and a boss having a smaller diameter than the bottom diameter of the bobbin. A shovel is pivotally connected to a terminating end of the bobbin feeding device. The shovel includes a groove having a width sufficient to enable the boss of the tray to fit into it. An actuator rotates the shovel so that each bobbin is scooped from its tray and slid down the shovel to a downstream production line.Type: GrantFiled: December 5, 1985Date of Patent: May 26, 1987Assignee: Murao Boki Kabushiki KaishaInventor: Hiroaki Sanno

Patent number: 4606509Abstract: An apparatus for facilitating the finding of the picking end of a yarn wound around a bobbin. The picking end of yarn is passed through the bore of the bobbin from top to bottom so as to be separated from the other and thereof and the yarn lines coiled around the bobbin, thereby avoiding the picking end of the yarn becoming lost or tangled with the other portions of the yarn.Type: GrantFiled: June 19, 1985Date of Patent: August 19, 1986Assignee: Murao Boki Kabushiki KaishaInventor: Sanno Hiroaki

Patent number: 4474525Abstract: The present invention relates to the construction of a storage apparatus for temporarily storing a large number of yarn packages (yarn wound on cones or taper cones). The storage apparatus is so arranged that many yarn packages automatically aligned are accommodated in a small space so as to be readily taken out when required, while, for the storing, the large number of yarn packages fed thereinto are aligned on conveyers narrow in width in the direction of take-up axis, and through utilization of a yarn package holding frame which is adapted to be raised while simultaneously holding opposite sides of the yarn packages thus aligned, said holding frame is lowered during taking out of the yarn packages so as to leave the yarn packages held thereby on the conveyers, as the holding frame being further lowered.Type: GrantFiled: February 22, 1982Date of Patent: October 2, 1984Assignee: Murao Boki Kabushiki KaishaInventor: Yoshio Murao
