Claims

[Scope of Claim for Utility Model Registration] 1. A main body that is movably or fixedly provided in front of the frame of a roving frame, so that the full bobbin mounting peg and the empty bobbin mounting peg can be moved to an exchange position opposite to the bobbin wheel. In addition, it is equipped with an exchange arm for hanging the bobbin that can move back and forth and up and down, and after the exchange arm takes out the full bobbin on the bobbin wheel onto the peg, it supplies the empty bobbin on the peg onto the bobbin wheel. In the tube changing device of the roving machine that operates, a first bobbin locus, through which the empty bobbin passes when the changing arm returns from the bobbin wheel position to the peg position with the empty bobbin suspended, and the empty bobbin are attached to the machine stand or main body. The light is projected across at least one of the second bobbin locus that the bobbin passes when it falls forward on the bobbin wheel, and the third bobbin locus that it passes when the full bobbin falls backward on the peg. A safety device for a tube switching device for a rover machine, characterized in that it is equipped with a phototube and a control device that stops the tube switching operation when the light emitted from the phototube is interrupted during a predetermined period of time. . 2. The main body is fixedly disposed in front of the machine, and the main body is equipped with a conveyor that can move left and right, in which a large number of pegs for loading full bobbins and pegs for loading empty bobbins are alternately arranged in two rows, and a bobbin rail. Exchangeable arms for hanging bobbins corresponding to the bobbin wheels arranged alternately in rows were provided so as to be movable back and forth and up and down, and full bobbins on each bobbin wheel were taken out all at once onto the pegs by the exchangeable arms. The tube switching device is configured to feed the empty bobbins on the rear peg onto the bobbin wheel all at once, and one phototube is placed between the front and rear peg rows, between the two peg rows on the top of the conveyor, and between the bobbin rail and the conveyor. A safety device in a tube switching device for a roving frame according to claim 1, characterized in that the safety device comprises: 3 The main body is arranged in front of the machine so that it can be moved left and right, and the main body is equipped with a peg for loading a full bobbin and a peg for installing an empty bobbin that can be moved up and down, as well as an exchangeable arm for hanging the bobbin that can be moved back and forth and up and down. In preparation for this, the tube changing device is configured so that a predetermined number of full bobbins on the bobbin wheel are taken out onto the peg by the changing arm, and then empty bobbins on the peg are fed onto the bobbin wheel, and the phototube is aligned with the first bobbin trajectory. In the tube changing device for a roving frame as claimed in claim 1, the device is arranged so as to project light across the overlapping portion of the second bobbin trajectory and the third bobbin trajectory. Safety device. 4. A safety device in a tube switching device for a revolving frame as set forth in claim 3, characterized in that the phototube is disposed only in the main body which can be moved left and right.
