Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an upper roll, a lower roll, a motor for periodically rotating and stopping the upper roll and the lower roll, and a motor provided on a motor output shaft. The present invention relates to a high-speed NC roll feeder that includes a drive gear that transmits a rotation torque to upper and lower rolls and intermittently supplies a material between the upper and lower rolls.

<Prior Art> Conventionally, as a roll feeder of this type, Japanese Patent Publication No. 59-16
Those described in Japanese Patent No. 853 (see especially FIG. 3)
It has been known.

This roll feeder is integrated with the upper and lower rolls, the upper and lower roll spur gears are arranged on the lower roll shaft so that they mesh with each other, and the lower roll shaft has a lower roll that meshes with the motor bevel gear. Bevel gears are arranged and the rotational torque of the motor is controlled by the motor bevel gear, the lower roll spur gear,
Rotate the lower roll by transmitting to the lower roll through the lower roll shaft in order, and then from the lower roll spur gear to the upper roll spur gear,
Rotate the upper roll by transmitting it to the upper roll through the upper roll in order, and rotate the upper and lower rolls at the same peripheral speed, but in opposite directions to each other, so that the thin plate-shaped material between the upper and lower rolls is rotated. It is supplied intermittently by frictional force.

<Problems to be Solved by the Invention> However, in this roll feeder, since the upper and lower rolls are integrated with the upper and lower roll shafts, the motor load and inertia are large, and the starting of the upper and lower rolls. However, there is a problem that braking control is difficult and it is difficult to supply the material at high speed and with high accuracy.

It is an object of the present invention to provide a high speed NC roll feeder capable of supplying a material at high speed and with high accuracy, focusing on the above problems.

<Means for Solving the Problem> In order to solve this problem, a high-speed NC roll feeder according to the present invention includes an upper roll, a lower roll, a motor for periodically rotating and stopping the upper roll, the lower roll, and In a high-speed NC roll feeder, which is provided on a motor output shaft, comprises a drive gear for transmitting the rotation torque of the motor to the upper and lower rolls, and intermittently supplies the material between the upper and lower rolls, The upper and lower rolls are separated from the upper and lower roll shafts, respectively, and are rotatably externally fitted to the lower roll shaft, while supporting the respective ends of the upper and lower roll shafts, the upper,
An upper roll gear and a lower roll gear are respectively arranged on the lower rolls, one of the upper roll gear and the lower roll gear is meshed with the drive gear, and the other is meshed with an intermediate gear meshed with the drive gear. To do.

<Advantageous effects of the invention> According to the high-speed NC roll feeder according to the present invention,
Since the lower roll shaft is supported separately from the upper and lower rolls and does not load the motor, the motor load and inertia can be greatly reduced, and high-speed and highly accurate material supply can be performed. .

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

The high speed NC roll feeder 1 according to this embodiment is
As shown in FIG. 2, a motor 4 for rotating and stopping the upper and lower rolls 2 and 3 and the upper and lower rolls 2 and 3 periodically.
And a drive gear 5 for transmitting the rotational torque of the motor 4 to the upper and lower rolls 2, 3 side, and intermittently supplies a material (not shown) between the upper and lower rolls 2, 3.

The upper and lower rolls 2 and 3 are separated from the upper and lower roll shafts 6 and 7, and are rotatably fitted on the upper and lower roll shafts 6 and 7, respectively. Both ends of the lower roll shaft 7 are fixedly supported by the frame 8. Upper and lower roll gears 9 and 10 are arranged on the upper and lower rolls 2 and 3, respectively.
Meshes with the drive gear 4.

On the other hand, the high speed NC roll feeder 1 includes an intermediate gear 11 that meshes with the drive gear 5 and the upper roll gear 9, and an intermediate gear 11.
A release shaft 12 that rotatably supports 11 and both ends of which are rotatably supported by a frame 8, and a release shaft 12 at one end 13a side.
Release arm 13 fixedly supported by
Presser spring 1 that presses 13 downward at the other end 13b side
4 and are provided. The upper roll shaft 6 is fixed to the other end 13b side of the release arm 13.

In the high-speed NC roll feeder 1 having the above structure, the rotation torque of the motor 4 is transmitted to the lower roll 3 via the drive gear 5 and the lower roll gear 10 in this order. At the same time, the rotation torque of the motor 4 is transmitted to the upper roll 2 via the drive gear 5, the intermediate gear 11, and the upper roll gear 9 in this order. Therefore, the rotation directions of the upper and lower rolls 2 and 3 are opposite to each other. The peripheral speeds of the upper and lower rolls 2 and 3 are set to be the same.

As is clear from the above description, the high speed according to this embodiment
According to the NC roll feeder 1, the upper roll shaft 6 is supported by the release arm 13 which is fixedly supported by the release shaft 12 which is rotatably supported by the frame 8, while the lower roll shaft 7 is fixedly supported by the frame 8. Therefore, the upper and lower roll shafts 6 and 7 do not act as a load on the motor 4, and therefore,
The motor load and inertia can be greatly reduced, and high-speed and highly accurate material supply can be performed.
