(Prior Art) FIG. 11 shows a pipe thread bobbin with a peg tray used in the present invention. In the figure, 1 is a disc-shaped peg tray, 2 is a bobbin standing on the peg tray 1, and 3 is a bobbin. It is a tube thread wound around 2.

Further, FIGS. 12 and 13 show an example of a conventional vertical conveying device for a bobbin bobbin, in which 4 is a base frame provided on a floor surface 5 and 6 is a conveyor erected on the base frame 4. As shown in FIG. 13, the conveyor frame 6 is integrally formed by dividing the forward path and the backward path into upper and lower parts. And in FIG. 12, 6a is a lower curved portion, and 6b
Is an intermediate vertical portion, and 6c is an upper curved portion. Reference numeral 7 is an endless transmission belt, 7a (see FIG. 13) is a wide base belt guided by the conveyor frame 6, and 7b is a rough top belt attached to the central portion of the base belt 7a. Further, in FIG. 12, 8 is an end roller provided at each of the folded back end portions of the transmission belt 7, 9 is a drive roller provided in the base frame 4, 10 is a guide roller, and 11 is a tension roller.

However, this device drives the transmission belt 7 by rotating the driving roller 9, and the friction transmission between the transmission belt 7 and the peg tray 1 raises or lowers the bobbin 2 integral with the peg tray 1 along the conveyor frame 6. It is like this.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional device, as shown in FIG. 12, when the radius of curvature R of the lower curved portion 6a of the conveyor frame 6 is small, the tube yarn 3 interferes, The radius of curvature R cannot be made smaller than the state shown in FIG. Therefore, there is a problem that a large installation space for the transfer device is required, the layout between the conveyors is limited, and the economical burden is increased.

In addition, the vertical conveyor that uses the elasticity of the base belt 7a and the frictional force of the rough top belt 7b not only cannot be conveyed due to the slight wear of the belt, but it also causes a malfunction if dust such as cotton wool accumulates in the conveyor frame 6. There was a problem that it was easy to raise.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, in a bobbin bobbin conveyor that is mounted on a peg tray and conveyed, an endless transmission belt that frictionally transmits in contact with the bottom surface of the peg tray is provided. , Extending along a desired path including a vertical portion via a grooved belt guide and a guide pulley so that it can be driven, and two guides slidably contacting the upper surface of the peg tray are provided along the transmission belt, The peg tray is elastically pinched between the guide and the transmission belt, and the passage of the peg tray composed of the transmission belt and the guide is laid at a desired position while being twisted, so that the pipe bobbin is conveyed while being twisted. Thus, a transport device for the bobbin thread bobbin is configured.

(Operation) As described above, in the present invention, the passage including the vertical portion of the peg tray including the transmission belt and the guide is laid at a desired position while being twisted. Therefore, for example, the radius of curvature of the concave curved portion of the conveyor frame is set. There is no risk of the bobbin bobbins interfering with each other even when the diameter is significantly smaller than the conventional one. Therefore, a large installation space for the transfer device is not required as in the conventional case, the layout between the conveyors is facilitated, and the economical burden is reduced.

Further, in the device of the present invention, an endless transmission belt that frictionally transmits in contact with the bottom surface of the peg tray is stretched along a desired path including a vertical portion via a grooved belt guide and a guide pulley, and can be driven. Since the two guides slidably contacting the upper surface of the peg tray are provided along the transmission belt and the peg tray is elastically clamped between the guide and the transmission belt, the peg tray is elastically pressed by the transmission belt. . Therefore, even if the power transmission belt is slightly worn, there is no possibility that the belt cannot be conveyed as in the conventional device, and the passage of the peg tray has much more vacant spaces than the conventional device. It almost never occurs.

Furthermore, since the peg tray is elastically held, even if there is some dimensional variation in the peg tray, it can be absorbed sufficiently, and if the pressure applied to the peg tray is properly selected, the bobbin bobbin during continuous transfer can be obtained. It is also possible to accumulate.
