Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a lifting guide device for yarn tows raised at the end of a transfer conveyor, and is particularly suitable for transferring synthetic fiber tows from a drying process to a cutting process. , relates to a guide device for raising yarn tows from the end of a setter conveyor.

[Prior art]

In the process of drying the synthetic fiber yarn tow, as shown in Figure 3, the yarn tow T that has been dried in a dryer is
At the end of the setter conveyor 31 of the dryer, the material is vertically raised by a take-up roller 33 provided above while being guided by a fixed guide 32 along the way, and then passed through a group of guide rollers 34 and a dancer roller 35. Cutter 36 in the cutting process
The cutter 36 cuts the staple into a predetermined length.

In the connection process between the drying process and the cutting process, if the cutter 36 is to be stopped due to some abnormality occurring, the setter conveyor 31 is moved immediately before the tow T falls from the conveyor because it is desired to avoid stopping the process before the drying process as much as possible. I won't stop until
On the other hand, even if the setter conveyor 31 is stopped at the same time as the cutter 36 is stopped, the setter conveyor 31
1 does not stop immediately due to its inertia, but stops after a slight time lag. Therefore, the end of the yarn tow T on the setter conveyor 31 passes directly below the fixed guide 32 and stops at a position further forward, where the retention portion A of the yarn tow is located. Occur. If operation is resumed in a state where such a retention section A exists, interference between the rising yarn tow T and the retention section A, and reversal of the retention tow may occur, resulting in single yarn breakage or tow disturbance. , it also causes cutting spots caused by the cutter 36.

[Purpose of invention]

The purpose of this invention is to solve the above problems,
To provide a yarn tow raising device in which the raised yarn tow does not interfere with a retention part or cause disturbance when restarting operation after stopping the device.

[Structure of the idea]

To achieve the above object, the yarn tow raising guide device of the present invention includes a taking means above the terminal end of the conveyor, and while raising the yarn tow transferred to the terminal end of the conveyor by the taking means, In a device that continuously processes the yarn by the next yarn processing means such as a cutter, a yarn guide is provided between the terminal end of the conveyor and the take-up means to guide the yarn tow raised from the conveyor, and this yarn It is characterized in that the strip guide is movable in the transport direction of the conveyor.

[Example of idea]

The present invention will be explained below with reference to embodiments shown in the drawings.

In Figures 1 and 2, 1 is a synthetic fiber yarn tow T
This is a setter conveyor that conveys the setter conveyor 1 in a dryer, and the figure shows the terminal end of the setter conveyor 1 at the outlet of the dryer. A take-up roller 2 is provided on the upper floor 7 above the end of the setter conveyor 1, and the take-up roller 2 lifts up the yarn tow T that has been conveyed to the end of the conveyor vertically upward. ing. Between the terminal end of the setter conveyor 1 and the upper take-up roller 2, a start-up guide device 8 of the present invention, which will be described later, is fixedly provided on a base 9 on the middle floor, and further fixed above it. A guide 2 is provided. The above take-up roller 3
The yarn tow T taken up is then guided to a cutter 6 via a guide roller group 4 and a dancer roller 5, where it is cut into staples.

The start-up guide device 8 has a pair of rails 11, 11 fixed on the pedestal 10, which are parallel to the moving direction of the setter conveyor 1, and
A cart 12 is provided that can reciprocate along 1. The carriage 12 has a yarn guide 13 extending laterally.
is fixed, and the yarn guide 13 is adapted to reciprocate along with the carriage 12 along the moving direction of the setter conveyor 1. At both ends of the cart 12, there are sprockets 14 provided at both ends of the frame 10,
Both ends of the chain 15 wound around the sprocket 14' are connected to each other, and one of the sprockets 14 is
It is designed to be driven by a motor 16 that can freely rotate in forward and reverse directions. Therefore, by controlling the motor 16, the carriage 12 is moved to the yarn guide 1.
3, it can be moved back and forth along the rails 11, 11.

17 is a monitor camera, and 18 is a monitor television. A monitor camera 17 monitors the terminal end of the setter conveyor 1 and the start-up guide device 8, and displays the situation on a monitor television 18. This monitor camera 17 can be remotely controlled by a control panel 19 provided near the cutter 6 and monitor television 18.
9, the motor 16 can be controlled to rotate in forward and reverse directions.

In the above-mentioned apparatus, when the cutter 6 is stopped due to some abnormality during steady operation, the setter conveyor 1 is stopped as explained in the conventional apparatus shown in FIG.
A retention portion A of the yarn tow T is formed at the terminal end of the yarn tow T. However, when restarting the operation, the motor 16 is controlled while the terminal end of the setter conveyor 1 and the start-up guide device 8 are monitored via the monitor camera 17 and the monitor television 18.
2 and operate the yarn guide 13 to position it directly above the end of the yarn tow T on the setter conveyor 1. By moving the yarn guide 13 in this way, it is possible to correct the condition so that the yarn tow T does not accumulate in the part A, so when restarting the operation, the yarn tow T can be moved without causing interference etc. Can be set up smoothly. Therefore, it is possible to reduce the occurrence of single yarn breakage, tow disorder, or cut spots caused by the cutter.

In addition, in the above embodiment, the yarn tow T after startup
Although this process is cutting by the cutter 6, the present invention is also applicable to other processes other than cutting.

[Effect of idea]

As described above, the present invention provides a yarn guide between the end of the conveyor that conveys the yarn tow and a take-up means provided above the conveyor for raising the yarn tow, and the yarn guide is connected to the end of the conveyor that conveys the yarn tow. Since it is configured to be movable in the direction, when restarting operation after stopping the device, by moving the yarn guide to an arbitrary position, it is possible to correct the condition so that there is no accumulation of yarn tows on the conveyor. As a result, the yarn raised from the conveyor can be raised without interfering with the above-mentioned retention section. Therefore, it is possible to reduce the occurrence of single yarn breakage, tow disorder, cut spots caused by the cutter, and the like.
