The base plate 113 becomes an object on which the pressure roller 112 is displaceable. The moving plate 115 is disposed to advance or retreat along the horizontal direction H toward the base plate 113. The adjustment link 116 is a link that adjusts the position of the pressure roller 112 so that the pressure roller 112 approaches or moves away from the central axis of the object O by interlocking with the movement of the moving plate 115. The moving driver 117 is a component that generates a driving force that moves the moving plate 115.

The rotation drive unit 131 is a configuration in which the rolling unit 111, specifically, the pressing roller 112, rotates the rolling unit 111 while pressing the object O. In this case, the rotation axis of the rolling unit 111 may be a straight line along the horizontal direction (H). The rotation drive unit 131 may have a motor 132, an intermediate shaft 136, and bushings 138a and 138b.

The motor 132 is a component that generates rotational force. The rotational force of the motor 132 is transmitted to the driving pulley 133 connected to its output shaft. Further, the driving pulley 133 rotates the driven pulley 135 by the rotational force via the belt 134.

Each shaft 136 is connected to the driven pulley 135 to rotate together with the driven pulley 135. Each shaft 136 may be arranged along the horizontal direction H, and may also extend along a direction generally perpendicular to the arrangement direction of the belt 134. Each shaft 136 may be a rod having a hollow portion 136a. Each shaft 136 may be rotatably supported by a support bracket 137. Each of these shafts 136 is connected to the base plate 113 and transmits the rotational force of the motor 132 to the rolling unit 111.

The bushings 138a and 138b are installed in the driven pulley 135 or the intermediate shaft 136, so that the relative rotation of the reference shaft 151 to be described later with respect to them occurs smoothly. The bushings 138a and 138b are a material that slides easily and may be formed in a cylindrical shape.

The correct positioning module 150 may include a reference shaft 151, a forward and backward driving unit 153, and a position limiting unit 156.

The reference shaft 151 is disposed to extend from the rotation drive unit 131 side to the rolling unit 111 side through each shaft 136. Specifically, the reference shaft 151 may be inserted into the hollow portion 136a (FIG. 2) of each shaft 136 and arranged along the same direction as the intermediate shaft 136. Furthermore, the reference shaft 151 is positioned corresponding to the object O at a height between the pair of pressing rollers 112.

The advance and retreat drive unit 153 is connected to the reference shaft 151 and is configured to advance it toward the rolling unit 111 in the horizontal direction H or vice versa. To this end, the advance and retreat driving unit 153 may be a cylinder 154 disposed along the horizontal direction H.

The position limiting unit 156 is configured to limit the forward and backward position of the forward and backward driving unit 153 by acting on the forward and backward driving unit 153. To this end, the position limiting unit 156 is connected to the forward and backward driving unit 153 and may be arranged along a vertical direction (V).

Referring to the drawings, the drive cylinder 154 has a pair of rods (155a and 155b) extending in both directions. Specifically, the first rod 155a is connected to the reference shaft 151 through the coupler 152, and the second rod 155b extends in a direction opposite to the reference shaft 151. The first rod 155a and the second rod 155b may be moved to the left or right in the drawing along the horizontal direction H according to the operation of the driving cylinder 154.

The position limiting unit 156 is configured to act on the second rod 155b. To this end, the position limiting unit 156 may have a dog 157 installed on the second rod 155b. The dog 157 is installed on the second rod 155b and may have an outer diameter larger than that of the second rod 155b.

Corresponding to the dog 157, the position limiting unit 156 may further have a stopper 158. The stopper 158 may be disposed along the height direction V crossing the extending direction of the second rod 155b. When the dog 157 moves in the horizontal direction (H) together with the second rod 155b, the stopper 158 meshes with the dog 157 at the set position, so that the dog 157 and the second rod 155b, furthermore reference It is a configuration that prevents the shaft 151 from moving any more.

The second rod 155b and the dog 157 may be wrapped by the housing 159. A stopper 158 may be installed in the housing 159.

5 is a partially enlarged front view mainly showing the stopper 158 of FIG. 4.

Referring to this drawing, the stopper 158 may have a locking member 158a and a stop cylinder 158b.

The stop cylinder 158b is configured to drive the locking member 158a forward and backward toward the second rod 155b. The stopper 158 allows the locking member 158a to move in the vertical direction V in the inner space of the housing 159. The driving force of the stop cylinder 158b is transmitted to the locking member 158a through the connecting rod 158c.

A spinning processing method using the above spinning processing equipment 100 will be described with additional reference to FIG. 6. 6 is a flowchart illustrating a spinning process method for an object according to another embodiment of the present invention.

Referring to this drawing (and FIGS. 1 to 5), the spinning processing method includes a reference surface providing step (S1), an object positioning step (S3), a reference shaft retracting step (S5), and a spinning operation performing step (S7). It may include.

In the step of providing the reference surface (S1), the reference shaft 151 is advanced toward the pressing roller 112 so that the reference surface 151a is located at a set position in the working area of the pressing roller 112. Thereby, the reference shaft 151 protrudes toward the working area beyond the end of each shaft 136 in a state located within each shaft 136 (see FIG. 1) (see FIG. 3).

In the object positioning step S3, the object O is introduced from the left side of the drawing in FIG. 1 toward the working area of the pressure roller 112, and then comes into contact with the reference surface 151a positioned at the set position. Thereby, the object O is stopped by the reference surface 151a and is positioned at that position.

In the reference shaft retraction step S5, the reference shaft 151 provided with the reference surface 151a is retracted in a direction away from the set position.

In the spinning operation performing step (S7), the rotation drive unit 131 rotates the rolling unit 111 through an intermediate shaft 136. Thereby, the pressure roller 112 presses the object O so that the diameter of the object O gradually decreases. Here, the moving drive unit 117 allows the pressure roller 112 to move in a direction from a distance away from the central axis of the object O through the moving plate 115 and the adjustment link 116 to a closer position, The outer diameter is reduced and the deformation is made.

Among these working steps, in the reference surface providing step (S1), a dog 157 must be prepared on the second rod 155b of the driving cylinder 154 connected to the reference shaft 151 through the first rod 155a. . In response to the dog 157, the stop cylinder 158b advances the locking member 158a. Accordingly, when the locking member 158a is caught by the dog 157, the reference shaft 151 is stopped and the reference surface 151a is positioned in place.

In addition, the reference shaft 151 may be used to discharge the object O after the spinning operation performing step S7. In this case, the reference shaft 151 may advance further toward the rolling unit 111 than when the reference surface 151a is provided at the set position.

The spinning processing equipment and method for the object as described above is not limited to the configuration and operation method of the embodiments described above. The above embodiments may be configured so that all or a part of each of the embodiments may be selectively combined and various modifications may be made.
