1 to 2, the rolled material (R) is generally a long rod-shaped, it should be transported in the horizontal or vertical direction to be placed in a predetermined position for processing.

The horizontal conveying apparatus of the rolled material according to an embodiment of the present invention for this purpose, the frame 10, the roller 20, the cylinder 30, the encoder 32, the transfer car 40 and control Unit 50 may be included.

The frame 10 may be a frame for supporting the plurality of rollers 20 so that the rolled material R may be vertically or horizontally transferred to the upper portion of the frame 10. It is connected to one side of the frame 10 may be formed of a plate-shaped upper plate 11 having a predetermined height.

The upper plate 11 is provided at the upper end of the frame 10 and is formed between the roller 20a and the roller 20b. The top plate 11 is preferably formed so that both ends do not contact each roller 20a, 20b so that rotation of the roller 20a, 20b is not obstructed. In addition, the upper plate 11 may be in the form of a plate formed to be spaced apart at regular intervals so that the body 41 of the transport car 40 can pass, so that the transport car 40 can pass.

The roller 20 may transfer the rolled material R in a longitudinal direction, that is, in a direction perpendicular to the axis of the roller 20. The roller 20 is provided with a plurality on one side of the frame 10, each of which is formed in a row arranged in a line at a predetermined interval, the rolling material (R) can be placed on the upper side.

The cylinder 30 is arranged in the axial direction of the roller 20. The cylinder 30 is driven by hydraulic pressure or pneumatic or the like, and the rod 31 may be provided at one side thereof to move forward and backward according to the driving.

The rod 31 is inserted into the cylinder 30 while one side protrudes out of the cylinder 30, and can be adjusted by the pressure applied to the cylinder 30. The rod 31 is to transport the rolled material R horizontally at a predetermined position, and an end thereof may be coupled to one side of the transfer car 40. The encoder 32 may be formed on one side of the cylinder 30 to detect the moving distance of the rod 31.

Encoder 32 is a device that can measure the movement occurring in the rod 31 formed in the cylinder 30, it may be to enable the movement control of the rod 31. Specifically, the encoder 32 is a converter that outputs an analog value, such as a rotation angle and a position movement amount, as a coded electric signal so that it can be treated as a digital value. For example, it serves as a measuring instrument that accurately measures displacements, such as the amount of movement and rotation generated in the rod 31.

One side of the transfer car 40 is coupled to the rod 31, the rolling material (R) by the operation of the cylinder 30 may be moving forward or retracted along a direction parallel to the axis of the roller 20. . Transport car 40 is provided with a body 41 having a wheel 43, the upper portion of the body 41 may be formed with a pressing portion 42 that serves to press and push the rolling material (R). .

The rod 31 for pushing and moving one side of the transfer car 40 is controlled by the encoder 32. The rod 31 is controlled to control the moving distance of the cylinder 30 based on the detection result of the encoder 32. It is possible for the unit 50 to be provided.

In addition, the control unit 50 receives the value output from the encoder 32 when the rod 31 does not reach the input position, and re-drives the rod 31 to control to accurately move to the desired position. It is preferable to

Figure 3 is a partially enlarged cross-sectional view showing a schematic view of the transport car of the rolled material horizontal transfer apparatus according to an embodiment of the present invention.

Referring to this figure, the rail 12 for guiding the path so that the wheel 43 of the transport car 40 can move can be installed on the top of the frame 10.

The rail 12 may be in the form of surrounding the wheel 43 so that the wheel 43 is not separated. Specifically, the wheel 43 may be a portion connected to the body 41 has a smaller diameter and the outside thereof has a larger diameter. The inner space of the rail 12 may be opposite to the shape of the wheel 43 so as to accommodate the wheel 43 so that the wheel 43 can move in the rail 12. The rail 12 is formed to be fixed to the upper end of the frame 10, and the height of the body 41 of the transport car 40 may be equal to the diameter of the roller 20. In addition, since the pressing portion 42 must push the rolled material R in the horizontal direction, the pressing portion 42 may be formed to protrude upward of the body 41.

Figure 4 is a flow chart for explaining the rolling material horizontal transfer method according to an embodiment of the present invention.

Referring to the drawings, the rolling material horizontal transfer method according to an embodiment of the present invention, the step of transferring the rolling material (R) in the direction crossing the axial direction of the roller 20 by using the roller 20 (S10) ) And driving the cylinder 30 so that the transfer car 40 connected to the cylinder 30 moves along the axial direction of the roller 20 (S20), and a rod 31 formed in the cylinder 30. Sensing the moving distance of the step S30 and horizontally transferring the rolled material R to the set position, and finally feeding back the position of the rod 31 moving to the set position (S40). .

In the step S10 of transferring the rolled material R in the direction intersecting the axial direction of the roller 20, the roller 20 is rotated to move the rolled material R in a direction parallel to the axial direction of the roller 20. Move to a certain position.

The rolled material R thus moved along the rotational direction of the roller 20 should be transferred to a predetermined position in a direction horizontal to the axis of the roller 20 for further processing.

To this end, the transfer car 40 moving along the rail 12 formed at the top of the frame 10 is used.

A wheel 43 is formed in the body 41 of the transport car 40 and moves along the rail 12 in a direction parallel to the axis of the roller 20. At this time, the cylinder 30 is driven to move the body 41 of the transfer car 40.

On one side of the cylinder 30, the rod 31 coupled with the transfer car 40 pushes and moves the transfer car 40 to a predetermined position by the pressure of the fluid or air applied to the cylinder 30. .

At this time, the rolling material (R) is moved to the upper plate 11 by pushing the rolling material (R) to the pressing portion 42 formed on the upper end of the transport car 40, the horizontal transfer of the rolling material (R) is made.

As such, when the rolled material R is transferred to the predetermined position by the transfer car 40, the step S30 of detecting the moving distance of the rod 31 is performed. At this time, the sensing distance of the rod 31 is the encoder 32, and measures the displacement of the cylinder 30, etc. and transmits an input value to the control unit 50.

The control unit 50 receives the input value from the encoder 32 and drives the rod 31 to the input position.

Finally, the step (S40) of feeding back the position whether the rod 31 has moved to the preset input position is executed.

After the rod 31 driven through the step S30 of detecting the moving distance moves the rolled material R to a predetermined position, the encoder 32 receives the displacement value of the rod 31 again and receives the rolled material ( Feedback is made whether R) has been moved to the desired position.

At this time, if the input value received from the encoder 32 is different from the set position, this input value is transmitted back to the control unit 50.

The control unit 50 completes the position feedback step S40 by driving the rod 31 again to move the rolled material R to the set position.

The rolled material horizontal transfer apparatus and method as described above are not limited to the configuration and operation of the embodiments described above. The above embodiments may be configured such that various modifications may be made by selectively combining all or part of the embodiments.
