Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a tow storage device for storing spun synthetic fiber tow in a can.

[Prior art]

As a method of storing tow in a can placed on the floor, there is a method described in Japanese Patent Publication No. 58-51867, in which the tow is sucked with an ejector or the like and is stored by pendulum movement back and forth and left and right. method is known.

As a swinging means, two motors are generally arranged in orthogonal directions, one of which is installed on a fixed frame, and the other motor installed in a perpendicular direction. A method is used in which the motor is swung together with a motor stand, an ejector is attached to an extension of the motor shaft, and both are swung back and forth and left and right.

However, with these methods, the capacity of one motor becomes large because one motor swings the ejector together with the other drive system.

In addition, in order to load the tows evenly, it is preferable to keep the moving speed of the tow falling trajectory constant, but when the tow is directly oscillated by the rotational movement of a motor as in these methods, the rotational speed must be changed from time to time. The drawback is that the motor control system becomes quite complex because of the need to move the motor.

〔Effect of the invention〕

As described above, one aspect of the present invention includes a swinging frame that is swingably attached to a fixed frame installed on a fixed frame via a first support shaft, and a swinging frame that is orthogonal to the first support shaft. a tow swing-out tube that is swingably attached via a third support shaft in the direction of the tow swing-out tube; It is swingably installed in the frame,
and a swinging arm that swings the tow swinging tube in a direction perpendicular to the swinging direction of the swinging frame, and a swinging arm that is installed on the pedestal and that rotates the first support shaft and the second support shaft in forward and reverse directions, respectively. Since it is composed of two rotating drive means, both motors can have the same capacity.

Another aspect of the present invention is a tow storage device having a driving means for swinging a tow ejecting tube back and forth and left and right, the driving means having a grooved structure fixed to a support shaft for swinging the tow ejecting tube. an arm, an endless chain installed in a direction perpendicular to the support shaft, a slider fixed to the endless chain and slidably fitted in the groove, and a drive motor for rotating the endless chain. Since the endless chain is parallel to the floor surface (tow loading surface), the movement speed between the rotation of the drive motor and the tow falling trajectory (the intersection of the tow delivery pipe extension axis and the tow loading surface) can be established in a linear relationship. It can be done. In other words, when the moving speed of the tow falling trajectory is made constant, the rotational speed of the drive motor can be kept constant.

Therefore, the control system for the drive motor becomes simple.
