Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention is for transferring roving bobbins doffed from a roving frame on one floor of a factory equipped with a lifting device such as an elevator to a spinning frame on another floor. The present invention relates to a method for transporting a roving bobbin to an installation position.

Conventional technology In the past, the roving bobbin doffed at the roving machine installation position was stored in the storage box of a transport car, the transport car was moved to the elevator installation position and placed on the elevator, and then the transport car was moved to the elevator installation position. After raising and lowering it to the N layer where the spinning frame is installed, the carrier is moved to the spinning frame installation position, where the roving bobbin is taken out from the storage box and hung on a bobbin hanger.

Problems to be Solved by the Invention As described above, in the case where the roving bobbin is stored in a storage box of a transport vehicle and transported, the roving bobbin is stored in the storage box so that the roving threads are not connected to each other or to the inner surface of the box. There was a problem that the rovings rubbed against each other and the rovings were biased.

Therefore, in order to solve the above problems,
As described in Publication No. 86, a pair of endless chains are rotatably arranged on a transport vehicle, and a plurality of horizontal support beams are swingably installed on these endless chains. A method in which the roving bobbin is inserted vertically has been proposed.

However, the method described in the above-mentioned publication requires complicated equipment such as endless chains for each transport vehicle, which increases the cost of the transport device.
It is necessary to suspend the roving bobbin from the bobbin hanger again at the spinning spinning a installation position, which poses a problem that requires a lot of labor and cost.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems by suspending the roving bobbin doffed from the roving machine from the bobbin hanger of the bobbin carriage supported by the first rail. , moving the carriage elements of the bobbin carriage in series to the lifting device position, changing the alignment of the carriage elements of the bobbin carriage to a parallel state, and supporting the parallel carriage elements on the third rail, and in that state.

By repeating the above operations, all the carriage elements 24af of the bobbin carriage 24f are connected in series, and in this state, the bobbin carriage 24f is moved to the spinning machine installation position Bf. The above-mentioned operation can be mechanized by a combination of well-known appropriate detection means and moving means, but it may also be performed by one operator's judgment and operation. Further, the engagement and disengagement between the coupling pin 77 and the coupling hole 78 may be performed manually by an operator.

In the present application, the first, second, and third rails may be arranged in double rows so that the bobbin carriage can be conveyed continuously. In addition, at the spinning machine position, instead of a spare rail, creel rails are installed in front of the creel and above the location where the rear row bobbin hangers are arranged, and the bobbin carriage is fed to the creel rail, and the bobbin hanger of the bobbin carriage is moved to the creel. It may be used as a bobbin hanger, and in that case, two rows of bobbin hangers in the bobbin carriage may be arranged in parallel, and the creel rail may be provided on one side of the spinning frame. Further, the elevating device may be constructed of a crane or the like that directly raises and lowers the third rail, and is not limited to an existing elevator.

Effects of the Invention As described above, in the present invention, the roving bobbin doffed from the roving machine is suspended from the bobbin hanger of the bobbin carriage guided by the first rail, and the bobbin carriage is transferred to the third rail. After supporting it, the lifting device is raised and lowered to the level where the spinning machine is installed, and then the bobbin carriage is guided to the second rail and moved to the spinning machine installation position, and the roving bobbin doffed from the roving frame is suspended. Since the roving bobbin is transported to the spinning machine installation position, even when transporting one roving bobbin to a different floor, damage to the roving of the roving bobbin can be minimized and yarn quality can be improved.Moreover, the bobbin hanger Since the roving bobbin suspended from the spinning machine can be mechanically transported to the spinning machine position, the labor required for transporting and loading and unloading the roving bobbin can be reduced, and labor savings can be achieved through automation. In addition, the carriage elements of the bobbin carriage are bent or separated at the connecting portion to change the alignment from a series state to a parallel state, and the bobbin carriage in that state is guided to the third rail and supported in the lifting installation. Therefore, a long bobbin carriage can be easily and quickly supported by a short R0 lowering device, which can shorten the transportation time, and also allows the existing elevator to be used to raise and lower the bobbin carriage. Eliminates the need for changes and reduces equipment costs.
