Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a main transport rail installed between a roving and a spinning process, a rail in a roving frame branched from the main transport rail, and a preliminary roving winding rail. A roving bobbin is hung on a carrier that travels along a branch rail such as the above, and the carrier is moved by a carrier to carry a preliminary roving winding onto the preliminary roving winding rail or an empty bobbin to a rail in the roving machine. The present invention relates to a connecting / disconnecting device for a carrier in a roving yarn conveying system for carrying in.

(Prior Art) Conventionally, as a roving yarn conveying system of this type, JP-A-61-194228
In the publication, a bridge rail for connecting a main transport rail and a branch rail to a transport machine is movably equipped at a connection position and a retracted position, and the bridge rail is accommodated in the bridge rail and the connection position and the retracted position of the bridge rail. It has been proposed to provide a connecting body having a connecting portion that is brought into contact with and separated from the transport body by moving between them. Further, in Japanese Unexamined Patent Publication No. 62-110928, a coupling releasing device that engages with a connecting mechanism provided at a predetermined position of the conveyor to release the connected state of the connecting mechanism is provided on the carrier carrying-in side of each spinning machine base. There has been proposed a bobbin carrier connection / disconnection device in which a drive device for driving the operating mechanism of the connection release device is provided in a transporter.

(Problems to be Solved by the Invention) However, in the former device, since the disconnection or connection between the carrier and the connector is performed by the rotation of the bridge rail mounted on the carrier, it is necessary to improve the stop position accuracy. Not only that, but it is also necessary to accurately store the connecting body in a predetermined position of the bridge rail. Further, in the latter device as well, since the driving device for driving the operating mechanism of the decoupling device is provided in the carrying machine, it is necessary to improve the accuracy of the stop position of the carrying machine. Furthermore, in this latter device, if the carrier is equipped with a carrier feeding device for feeding the carrier into the branch rail or sending it out from the branch rail, the installation position of the decoupling device is set to the carrier. The position can be close to the stop position, but in that case, since the carrier is equipped with a bridge rail, its drive unit, and a carrier feeding device, the carrier becomes large and heavy, There is a problem in that a rail dedicated to a carrier is required in addition to the rail on which the body travels. Further, the transporter itself is not equipped with a transporting device, and the transfer of the transporter to and from the branch rail separately proposed by the applicant of the present application is performed by retreating and advancing the transporter in a state of being connected to the transporter. If how to do,
When separating the carrier in the middle of the carrier, the distance between the carrier and the installation position of the decoupling device becomes large, and in some cases the distance may exceed 15 m. There is a problem in that the variation of the stop position of the connecting portion requiring the disconnection becomes 30 mm or more only by the rattling of the connecting links to be connected, and the disconnecting by the disconnecting device may not be performed smoothly.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, in the present invention, a rail in a roving frame branched from a main transport rail installed between a roving / spinning process and a preliminary roving winding. On a branch rail such as a rail, a reciprocating rotary position is arranged between an operating position at which the connecting mechanism provided at a predetermined position of the carrier can be engaged and a retracting position at which the engaging mechanism cannot be engaged, and at the operating position. Between the disconnecting lever that releases the connected state of the connecting mechanism by relatively moving in the state, and the engaging portion that is provided at a position near the connecting mechanism on the carrier and that is engageable with the engaging portion. An engaging lever provided with an engaging concave portion having a sufficient space in the moving direction of the engaging portion and a supporting member which is reciprocally movable along the branch rail and reciprocally moved by the drive device. And the engagement lever is Provided actuating means to arrange the working position the disconnecting lever when moved to the operative position of the engaging portion in engagement in the recess of position.

(Operation) In the present invention, the carrier travels along with the carrier along the main carrier rail in a state of being connected to the carrier, and needs to be detached into the branch rail which requires the carrier to be carried therein. When the connecting mechanism reaches a position substantially corresponding to the connecting / disconnecting device provided on the branch rail, the connecting mechanism is stopped together with the stop of the carrying machine. In this state, the disconnecting lever is arranged in a retracted position where it cannot engage with the connecting mechanism provided in the carrier, and the engaging lever is arranged in a retracted position where it cannot engage with the engaging portion provided in the carrier. There is. When the drive device is actuated in this state, the supporting member provided with the separating lever and the engaging lever is moved forward, and the engaging portion provided on the conveying body for the engaging lever is arranged in the engaging concave portion. The release lever is rotated to the position and the disengagement lever is disposed at the working position where the separation lever can be engaged with the rotation of the engagement lever. From this state, the support member is further moved in the forward direction or the carry machine is moved in the carry-out direction, so that the separating lever first engages with the connecting mechanism and the connecting mechanism is connected by relative movement with the carrier. The state is released, and then the engaging portion engages with the engaging concave portion to restrict the movement of the transport body located on the inner side of the branch rail with respect to the engaging portion. As a result, the transport body, which is engaged with the engaging recess of the engaging lever and whose movement is regulated as the transport machine moves, is disconnected from the transport body located closer to the transport machine than the engaging portion.

As described above in detail, according to the present invention, the separation of the roving bobbin transport units or the disconnection of the coupling mechanism for coupling the roving bobbin transport unit and the coupling body is performed at a position distant from the carrier by a large distance. Since it can be performed reliably even if the stop position of the machine is not so accurate, it is an excellent effect that it is possible to easily divide the carrier and easily cope with the case where the number of spindles of the spinning frame and the roving frame is different. Play.
