[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coiled plate, sheet, film or linear material such as metal, plastic, paper, etc. More particularly, the present invention relates to a coiled material insertion device for an uncoiler machine for inserting a coiled material into the uncoiler machine.

[0002]

2. Description of the Related Art Currently, in various industrial fields, an uncoiler machine is used which unwinds a coiled material and sends it to a processing machine in the next process. FIG. 5 shows an example of an uncoiler machine. This uncoiler machine has a base 71
And a headstock 7 slidably mounted on the base 71.
2 and a spindle 73 rotatably supported by the headstock 72.
A motor 75 mounted on the headstock 72 to rotate the main shaft 73 via a gear box 74, and a drum 76 attached to the tip end of the main shaft 73 to insert and hold the coiled material 80. Have been. The coiled material 80 is positioned by an end plate 77 attached to the drum 76 on the gear box 74 side.

As shown in FIG. 6, a coiled material insertion device for an uncoiler machine for inserting the coiled material 80 into the drum 76 is installed in front of the drum 76 in the front end direction.

Hereinafter, a conventional coil-shaped material insertion device for an uncoiler machine will be described with reference to FIG. FIG.
It is the top view which omitted a part which shows the conventional coil-shaped material insertion apparatus for uncoiler machines. As shown in FIG. 6, the first rail 3 and the second rail 5 for transporting the coiled material 80 are arranged at substantially right angles with the direction of the tip of the drum 76 of the uncoiler machine intersecting. Therefore, the crossing portion is a position where the coiled material 80 is inserted into the drum 76.

The drum 7 of the first rail 3 and the second rail 5
The end opposite to 6 is the carry-in / out and standby position for the coiled material 80 to be inserted next into the drum 76. That is, the used coiled material is carried out at the carry-in / out position, a new coiled material to be used from now on is carried in, and when not in use, the coiled material is in a standby state at this position.

[0006] In the uncoiler machine, when the processed product changes under the high-mix low-volume production, it is necessary to replace the coiled material 80 to be inserted into the drum 76 accordingly. Accordingly, the coiled material used so far is returned to the carriage by moving the drum of the uncoiler machine forward, and the carriage is moved to the carry-in / out position at the other end of the rail. Thereafter, the carriage on the other rail side is loaded with the new coiled material and moves from the loading / unloading position to the intersection of the rails to insert the new coiled material into the drum.

[0007] The operation of inserting the coil-shaped material is specifically described as follows. The intersection 7 of the first rail 3 and the second rail 5 is located near the tip of the drum 76 of the uncoiler machine. The work of inserting 76 is performed. That is, the first transport vehicle 81
When the insertion work is performed, the first carrier 81 is moved from the carry-in / out position to the front of the drum 76 on the first rail 3.

When inserting the coiled material 80 placed on the second transport carriage 82 into the drum 76, the carriage 3 provided with the auxiliary rail 84 for extending the second rail 5 is moved to the second carriage 5. This is performed by providing on the first rail 3 separately from or exchanged with the one carrier 81. That is, when the carriage 83 provided with the auxiliary rail 84 stops on the first rail 3 in a state where the positions of the second rail 5 and the auxiliary rail 84 are aligned, the second carriage 82 that has moved on the second rail 5 Moves on the auxiliary rail 84 on the carriage 83.
Then, the second transfer cart 82 is placed on the
Stops when the center axis of the coil-shaped material 80 coincides with the center axis of the coil-shaped material 80. Thereafter, when the carriage 83 slightly moves to the drum side and stops, the drum 76 moves in the direction of the coiled material 80, and the drum 76 is inserted into the coiled material 80. The entire second rail 5 is higher than the first rail 3 by the height of the carriage 83.

[0009]

However, as the operation of replacing the coil-shaped material becomes more frequent in small-lot production of many kinds, the following problems have become prominent. In the conventional coiled material insertion device for an uncoiler machine described above,
When transporting the coiled material 80 placed on the second transport trolley 82, there is a problem that a trolley 83 provided with an auxiliary rail 84 must be mounted on the first rail 3, which requires a lot of means. .

Further, it is necessary to accurately position the carriage 83 in order to allow the second carriage 82 to run smoothly on the auxiliary rail 84 of the carriage 83, and the positioning operation is troublesome and time-consuming. There was a point.

Further, since the height of the carriage is different between the first carriage 81 and the second carriage 82, the carriage cannot be shared, and a carriage provided with an auxiliary rail must also be prepared. Therefore, it was necessary to prepare various types of carts.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in consideration of the above-described problems. The height of a plurality of rails is made substantially the same to utilize a lower space where a plurality of rails intersect. An object of the present invention is to provide a coil-shaped material insertion device for an uncoiler machine having a simple structure capable of efficiently performing an insertion operation to a drum in a short time and easily exchanging the coil-shaped material.

The lower part of the hydraulic cylinder 23 is provided rotatably via an upper part of the cylinder support 21 and a pin 29, and the hydraulic cylinder 23 itself is rotatable about the pin 29. Therefore, the movement of the piston 25 in the left-right direction due to the rotation of the engagement member 17 can be absorbed by the rotation of the hydraulic cylinder 25 itself.

[0019] By this way, the upper and lower operation and the hydraulic cylinder 23 rotates itself in the piston 25 of the hydraulic cylinder 23, the engagement member 17 is made rotatable around the first rotation axis 11. Thereby, the first switching rail 9 can rotate around the first rotation shaft 11.

FIG . 2 is a plan view showing a main part of the coiled material insertion device for an uncoiler machine when the second switching rail 31 is used, and the first rail 3 is omitted. One end of the pair of second switching rails 31 is connectable to the second rail 5, and the other end is fixed to the second rotating shaft 32. The rotation mechanism 3 of the second switching rail 31
3 has the same configuration as the rotating mechanism 33 of the first switching rail 9. However, the rotation mechanism 33 of the first switching rail 3
Is provided on the uncoiler machine side of the rail crossing section 7, whereas the turning mechanism 33 of the second switching rail 31 is
It is provided at a position 90 degrees away from the rotation mechanism 15 of the first switching rail 3.

Further , on the drum 76 side of the uncoiler machine of the first switching rail 9, on the right side in FIG. 4, there is provided a stopping means 59 for positioning and stopping the wheels 55 of the carriage 57. . As shown in FIG. 4, the stop means 59 is variably provided on a support base 61 fixed on the first switching rail 9 via an adjusting member 63 having a nut and a screw structure. Thus, by finely adjusting the position of the stopping means 59 with the adjusting member 63, the transport vehicle 57
Can be accurately adjusted to be appropriate for the insertion operation.

Next, the first switch rail 9 first les - concatenated with Le 3 will be described with reference to FIGS. 3 and 4 for the stopper mechanism 35 for positioning the horizontally. The same stopper mechanism as the stopper mechanism 35 is used when connecting the second switching rail 31 to the second rail 5. FIG. 3 shows a plan view of a stopper mechanism 35 for positioning the first switching rail 9 and connecting with the first rail 3.

When the switching rail and the rail are connected, the stopper mechanism 35 keeps both rails horizontal and also has a function of supporting the weight of the carrier when the carrier is placed on the switching rail. And this stopper mechanism 3
5 is mainly composed of the stopper member 37 and the stopper member 37
And a hydraulic cylinder 41 with a switch provided on the stopper table 39. The stopper base 39 is formed in a box shape, and has a stopper member 37 provided therein. The stopper member 37 is provided in the piston 4 of the hydraulic cylinder 41 with switch.

As shown in FIG. 4, a second tapered portion 47 is formed at the contact portion of the stopper member 37 with the first switching rail 9, and a first tapered portion 49 provided at the tip of the first switching rail 9. And can be positioned. The switch-equipped hydraulic cylinder 41 is operated by a signal from a limit switch or a control device (not shown) so as to operate in synchronization with the movement of the first switching rail 9. That is, when turning the first switching rail 9 downward, the switch-equipped hydraulic cylinder 41 moves the stopper member 37 backward and separates it from the first switching rail 9.

On the other hand, when rotating upward from the position shown the first switch rail 9 by a two-dot chain line in FIG. 4, until the first switch rail 9 is pivotally moved upward from the stopper member 37 retracted After that, when the first switching rail 9 rotates to a position above the stopper member 37, the stopper member 37
Is moved forward, thereby bringing the second tapered portion 47 of the stopper member 37 into contact with the first tapered portion 49 of the first switching rail, and positioning the first switching rail 9.

Next, the operation of the coil-like material insertion apparatus for Anko Ira machine configured as described above. FIG.
FIG. 3 is a plan view showing the coiled material insertion device for an uncoiler machine when the first switching rail 9 is used.
When it becomes necessary to replace the coiled material 80 inserted in the drum 76 of the uncoiler machine, the drum 76 moves forward and the remaining amount of the coiled material 80 is reduced by the first switching rail 9.
It is placed on the upper carrier 57 (see FIG. 4).

A carriage 57 on which the coiled material 80 is placed
Is moved to the carry-in / out position on the first rail 9 and is put on standby for the next use (the coil-shaped material is replaced if necessary). Thereafter, the stopper member 37 of the first switching rail 9 is retracted by the operation of the hydraulic cylinder 41 with the switch, and the second tapered portion 47 of the stopper member 37 and the first tapered portion 49 of the first switching rail 9 are moved. Leave.

The hydraulic cylinder 41 with switch
Is performed after confirming that the carrier has passed the crossing section 7 by a synchronization device 69 such as a limit switch or a control device (not shown). Then, after the contact between the first switching rail 9 and the stopper member 37 is released, the first switching rail 9 rotates downward via the engagement member 17 and the first rotating shaft 11 by driving the hydraulic cylinder 23. Move.
Thereafter, as shown by the two-dot chain line in FIG. 4, the first switching rail 9 stops at a position substantially perpendicular to the device stand 19.

[0029] After confirming the stop of the first switch rail 9, upward rotation of the second switching rail 31 starts. The upward rotation of the second switching rail 31 is also performed by the same rotating mechanism 33 as the rotating mechanism 33 of the first switching rail 9. That is, first, the second switching rail 31 is rotated upward by the driving of the hydraulic cylinder 23 via the engagement member 17 and the second rotating shaft 32. At this time, the stopper member 37 is retracted to avoid interference with the second switching rail 31,
Must be within 9. This confirmation is performed by confirming the position of the second switching rail 31 with a limit switch (not shown) or the like.

When it is detected by a limit switch or the like (not shown) that the position of the second switching rail 31 has been rotated above the stopper member 37, the switch-equipped hydraulic cylinder 41 of the stopper mechanism 35 is driven to stop the stopper member. Move 37 forward. Then, the second switching rail 3
When the rotation of 1 is stopped, the second switching rail 31 is positioned and supported by the stopper member 37 to enable the movement of the carriage, thereby enabling the insertion of the coiled material.

In the present embodiment, the case where two of the plurality of rails intersect at a substantially right angle has been described. In addition to this, the state in which the switching rail has stopped rotating downward. The present invention can be implemented even if three or more rails cross each other as long as they do not interfere with each other.
