Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a carrier tool is movably arranged on a carrier rail provided from the roving machine to the spinning machine, and the roving bobbin is supported by the carrier tool and is transported by a transfer device. The present invention relates to a transport tool connecting device in a roving bobbin transporting device configured to transport a roving bobbin.

[0002]

[Prior art]

 Generally, a fully wound roving bobbin spun by a roving spinning machine is guided to a spinning machine by a roving bobbin transport device. This roving bobbin transfer device has a hollow transfer rail that opens at the bottom in a closed loop between the roving frame and the spinning frame, and a plurality of bobbin holders are mounted on the transfer tool that runs on this transfer rail. Is configured to be suspended and the carrier can be moved by a transfer device.

By the way, in recent years, the number of spindles on one side of the spinning frame has become significantly larger than the number of spindles on the roving frame. Therefore, conventionally, a plurality of conveying tools are connected to adjust the number of weights fed into the spinning machine (Japanese Patent Laid-Open No. 63-295727).

[0003]

[Problems to be solved by the device]

 However, in the conventional roving bobbin transfer device, a disconnecting device that disconnects a plurality of connected transfer tools is arranged at the branch portion between the main transfer rail and the branch rail, and this disconnecting device is operated by operating the cylinder. Due to this structure, the structure of the separating device is complicated and the weight is heavy, and there is a problem that the structure of the entire bobbin transporting device must be firmly formed. The present invention focuses on such points, and an object thereof is to provide a carrier tool connecting device capable of connecting and disconnecting each carrier tool with a simple mechanism.

[0004]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention arranges a fixed side engagement connecting tool at a rear end portion in a moving direction of each transport tool and a movable side engagement at a front end portion. A connecting tool is arranged, and the movable side engaging connecting tool is elastically biased in a state where the elastic body holds the connecting attitude, and the movable side engaging connecting tool is released from the engaging posture against the elastic force of the elastic body. It is characterized in that the switching operation tool for switching to is pivotally supported on the side wall of the transport rail in the vicinity of the rail switching device in a state permitting swinging in one direction along the rail installation direction.

[0005]

[Action]

 According to the present invention, the fixed side engagement connecting tool is arranged at the rear end portion in the moving direction of each carrying tool, and the movable side engagement connecting tool is arranged at the front end portion. The switching actuator that elastically urges the connection posture to maintain the movable posture against the elastic force of the elastic body and switches the coupling device to the disengaged posture is located near the rail switching device on the side wall of the conveyor rail. Since it is pivotally supported in a state in which it is allowed to swing in one direction along the rail installation direction, the movable side engagement coupling tool and the fixed side engagement coupling tool engage with each other by the self-operated movement of the transport tool. Will be canceled.

[0006]

[Effect of device]

 The present invention has the following effects because it is configured and operates as described above. (A) Elastically engage the fixed-side engaging connecting device arranged at the rear end of the conveying device with the movable-side engaging connecting device arranged in the next conveying device, and close the side wall of the conveying rail near the rail switching device. In this case, the movable engaging connector is switched to the disengaged posture by the switching actuator pivotally supported while allowing the swinging in one direction along the rail mounting direction. It is possible to release the engagement between the movable side engagement coupling tool and the fixed side engagement coupling tool by the self-operation by the movement of the tool, which does not require a complicated engagement releasing mechanism as in the prior art, and the structure is simple. It can be implemented simply and inexpensively.

(B) The switching operation tool for releasing the engagement between the transport tools is pivotally supported on the side wall of the transport rail in a state in which the swing is permitted in one direction along the rail installation direction. Therefore, the load of the switching actuator that acts on the transport rail is light, and the transport rail can be composed of weak ones. Therefore, the entire transport rail can be made lighter and the entire equipment can be made lighter. it can.
