DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for collecting an air core held by a chucking device of an unwinding machine.

[0002]

2. Description of the Related Art An unwinding machine is designed to rewind roll paper supported by a chucking device to supply continuous paper to a printing unit of a rotary press. This roll paper is
When the core is rewound to an empty core state with little or no remaining paper, it is collected and replaced with new roll paper. The work of collecting the air core is performed manually.

[0003]

However, manual collection of the air core places a heavy burden on the operator and may be accompanied by danger. Therefore, an object of the present invention is to provide a roll paper air core transfer device capable of efficiently collecting an air core without manual operation in order to solve the above problem.

[0004]

Means adopted by the present invention is to receive an air core held by a chucking device positioned at an air core transfer position of an unwinder, and to apply the air core to a roll paper pallet. An air core receiving portion that can be tilted, an elevating device that raises and lowers the air core receiving portion, and an elevating device that moves up and down with the air core receiving portion, and one end of the device rests on the bottom of the roll paper pallet. And a link mechanism for tilting the air core receiving portion to a transfer state by contacting the air core receiving portion.

In the present invention, the air core receiving portion is moved up and down by the elevating device to the air core receiving position gripped by the chucking device positioned at the air core transfer position, and the gripping of the chucking device is released. Then, the air core is delivered to the air core receiving portion, and the link mechanism is moved up and down by an elevating device together with the air core receiving portion that has received the air core, so that one end of the link mechanism is brought into contact with the bottom of the roll paper pallet to be air cored. The receiving portion is tilted to the transfer state, and the air core can be transferred from the tilted air core receiving portion onto the roll paper pallet.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roll paper transfer apparatus according to the present invention. 1 to 3 show an embodiment of the present invention. FIG. 1 is a side view showing an air core receiving portion in a standby state by a solid line and an air core receiving portion receiving an air core by a two-dot chain line. FIG. 2 is a front view, and FIG. 3 is a side view showing a state where an air core is transferred from a tilted air core receiving portion onto a roll paper pallet.

[0007] The unwinding equipment according to the present embodiment comprises an unwinding machine 1
And an air core transfer device 2 for roll paper. The unwinder 1 includes a plurality of sets of left and right turret arms 3 and 4 extending in the radial direction from the rotation center C, and chucking devices 5 and 6 provided near the ends of the turret arms 3 and 4, While rotating the turret arms 3, 4, the chucking devices 5, 6 can be stopped between the air core transfer position F (see FIG. 1) and the new roll paper receiving position G (see FIG. 3). The chucking devices 5 and 6 are connected to both ends of the core Ra of the roll paper R and rotatably support the roll paper R, and are detached and not connected to both ends of the core Ra of the roll paper R. You can choose.

[0008] The air core transfer device 2 for the roll paper R is disposed in the pit P, and is provided with a tiltable air core receiving portion 7;
The apparatus includes a lifting device 8 for raising and lowering the air core receiving portion 7 and a link mechanism 9 for raising and lowering the air core receiving portion 8 to tilt the air core receiving portion 8 to a transfer state. The elevating device 8 includes a lower base 11 fixedly disposed, an upper elevating platform 13, an intermediate elevating guide 12 including a link mechanism for guiding the elevating platform 13 movably up and down, and elevating the elevating platform 13. An operating tool (not shown) is provided from an air cylinder or the like, and the lift 13 is moved up and down from the lower standby position B to the upper transfer position A by the output of the operating tool.

The air-core receiving portion 7 includes a base 16 supported on a frame 13a forming a lift 13 of the lift device 8.
And a pillow part 1 long in the left-right direction attached and fixed on the base 16
7, and the air core Ra is received by a V-shaped or other concave groove 17 a formed on the upper surface of the pillow portion 17. The link mechanism 9 includes a base 13a and a base 1 that are four links.
6, a four-bar rotating link consisting of a connecting rod 18 and an input link 19, and the input link 1
9, the bottom end 10 of the roll paper pallet 10 stopped at the transfer position D (see FIG. 3).
The air core receiving portion 7 is configured to be tilted to the transfer state by abutting on a.

The roll paper pallet 10 has a V-shaped concave groove 10b for supporting the roll paper R and the air core Ra.
And 10c are formed, and the conveying position 20 including a chain conveyor and the like on both the left and right sides causes the standby position and the transfer position D
And move between them.

Next, the operation of the air core transfer device 2 will be described in accordance with the procedure for mounting the new roll paper R on the unwinder 1. As shown in FIG. 1, the air core Ra supported by the chucking devices 5 and 6 of the unwinder 1 is stopped at the air core transfer position F, and the air core receiving portion 7 of the air core transfer device 2 is moved up and down. The device 8 is moved up to the delivery position A, and the chucking devices 5 and 6 are released so that the air core Ra is transferred to the air core receiving portion 7. Next, after the air core receiving portion 7 that has received the air core Ra is once lowered to a position where it does not hinder the loading of the pallet 10, the pallet 10 on which the new roll paper R is placed is moved to the transfer position D by the transport device 20. Bring in and stop.

Subsequently, as shown in FIG. 3, while the air-core receiving portion 7 of the air-core transfer device 2 is being raised to the transfer position A by the lifting device 8, the input end 19a of the input link 19 of the link mechanism 9 is connected. The air core receiver 7 is tilted in the transfer state by contacting the bottom 10 a of the roll paper pallet 10, and the air core Ra is transferred from the tilted air core receiver 7 onto the concave groove 10 c of the pallet 10. Finally, the air core receiving unit 7 of the air core transfer device 2 is lowered by the elevating device 8 to the standby position B, and the transfer position D
Roll paper R placed on the stopped pallet 10
After the chucking devices 5 and 6 stopped at the new roll paper receiving position G of the unwinding machine 1 are connected to both ends of the pallet 10, the pallet 10 receiving the air core Ra is retracted to the standby position and unwound. One cycle of loading the new roll paper R into the machine 1 is completed.

[0013]

According to the roll paper air core transfer device according to the present invention, the air core received by the air core receiving portion can be efficiently collected by smoothly transferring the air core onto the roll paper pallet. This has an excellent effect that the load can be remarkably reduced and the worker can be released from dangerous work.
