BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device for feeding a roll material such as paper or non-woven fabric to a processing step.

[0002]

2. Description of the Related Art Conventionally, in order to supply a roll winding material such as paper or non-woven fabric to various processing steps, both ends of a core rod of the roll winding material are rotatably supported on a mount and, for example, the outer circumference of the roll winding material is supported. The roll winding material is fed while being driven by the contact between the section and the belt surface of the belt conveyor.

[0003]

According to the above construction, when the roll winding material runs out, the operation of the machine is stopped, the core rod is first removed from the mount, and the core rod of the new roll winding material is attached to the mount. Since both ends are supported, there is a problem that it takes a lot of trouble and the operation time of the machine becomes long, resulting in a significant decrease in operating rate.

[0004] Therefore, an object of the present invention is to provide a feeding device capable of quickly supplying a new roll material.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a support bar at both ends of a core rod of rolled material, and the core bar rolls in from the support frame. Two guide rails whose lower ends are opened so as to guide downward while engaging both ends of the guide rail, a head pulley is positioned below the lower end of the guide rails, and the forward side surface and the guide rails extend upward. Of the guide rail, a stopper device that is retractable so as to engage with the end of the core rod on the receiving part, and a high side is located below the lower end of the guide rail. In addition, the feeding device is composed of a discharge chute of the core rod and a gate which is provided at the lower end of the guide rail so as to be opened and closed by an appropriate means so as to hold the core rod by closing the guide rail.

[0006]

[Function] When both ends of the core rod of the rolled material supplied to the receiving portion are received and the guide rails are engaged with both ends of the core rod to lower the rolled material, the conveyor surface of the conveyor and the roll winding material The contact with a part of the outer circumference of the material stops the fall of the rolled material.

The stopped roll-wound material is rotated in the feeding direction by the conveyor, and the material fed by the rotation is transferred by the conveyor.

Further, since the diameter of the roll-wound material gradually decreases as it is fed out, the roll-wound material descends along the guide rails, and the last remaining core rod remains on the chute.

The core rod on the chute is discharged by opening the gate. The gate should be closed after discharging the core rod.

Further, both ends of the core rod of the roll winding material supplied to the receiving portion are supported, and the core rod is engaged with the protruding stopper device to stop the roll winding material.

The stopped roll material is supplied by immersing the stopper device immediately before discharging the core rod.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, reference numeral 1 designates a slightly inclined left and right two-strand receiving portion which is provided so as to receive both ends of a core rod a of a roll material A. A guide rail 2 is provided which is open at the lower end and guides downward while engaging the end of the core rod a downward from the end.

The above-mentioned guide rail 2 is composed of two vertical portions which face upward with a clearance for the passage of the core rod a, and two bent portions which are continuous from the upper ends of the vertical portions and which face obliquely upward rearward. Further, a rail for the receiving portion 1 having a gentle slope is formed rearward from the lower bent portion.

Reference numeral 3 denotes a belt conveyor in which the head pulley 4'is located below the lower end of the guide rail 2 and the distance between the forward surface and the guide rail 2 is gradually increased toward the top.

Reference numeral 4 denotes a stopper device provided on the receiving unit 1 so as to be retractable. In the illustrated stopper device 4, the lower end portion of the stopper device 4 is rotatably attached to the frame 5 via a pin 6, and both ends of the lower end of the rotating piece 7 and the frame 5 are rotatable. The cylinder 8 is attached, and the upper and lower ends of the rotating piece 7 are projected and retracted with respect to the upper surface of the receiving portion 1 by the expansion and contraction actions of the cylinder 8.

Numeral 9 is a left and right double-shooting chute for discharging the core rod a whose high end is located below the lower end of the guide rail 2. In the middle of this chute 9, a contraction action of a cylinder 10 causes a lever 11 to intervene the chute 9. Bar a protruding upward from the
If the receiving piece 12 is provided, the receiving piece 12 stops the core rod a which is rolled and discharged at a high speed by the rotation,
After that, the extension action of the cylinder 10 can rotate the receiving piece 12 in the retracted direction to release the stop of the core rod a, so that the core rod a can be gently discharged.

Reference numeral 13 denotes a gate which is provided at the lower end of the guide rail 2 and which can be opened and closed. The gate 13 is rotatably attached to the lower end of the guide rail 2 located on the discharge side of the core rod a via a pin 14 so that both ends of the gate 13 and the frame 5 are rotatable. The gate 13 is opened and closed by the contraction and extension actions of the cylinder 15 attached to the.

With the above construction, both ends of the core rod a of the rolled material A supplied to the receiving portion 1 by an appropriate method are supported, and the core rod is guided to the guide rail 2 by rolling of the rolled material A. When the roll material A is lowered while engaging both ends of a, the conveying surface of the belt conveyor 3 and a part of the outer periphery of the material A come into contact with each other (as shown in FIG. Since it is supported by the row-side back surface and the group of rollers 16 so that the belt is not affected at all, the roll material A is stopped from falling and the roll material A is driven in one direction. Therefore, the rolled material A is unwound and sent to the next step by the belt conveyor 3.

Since the diameter of the rolled material A gradually becomes smaller as it is fed out, the rolled material A descends along the guide rails 2, and the core rod a left at the end remains on the chute 9. The core rod a on the chute 9 opens the gate 13 for discharging, and closes the gate 13 after discharging.

The roll winding material A supplied to the receiving section 1
If both ends of the core rod a are received and the ends of the core rod a are engaged with the protruding stopper device 4, the next supply roll winding material A can be put on standby.

The roll material A in the waiting state is supplied by releasing the engagement of the core rod a by retracting the stopper device 4 immediately before the core rod a falls on the chute 9.

As shown in the figure, the ends of the upper arm 22 are fixed to both ends of the rotary shaft 21, and the end of the core rod a is engaged with the tip located inside the guide rail 2, and the rotary shaft is rotated. The end of the lever 25 is fixed to the second gear 24 meshed with the first gear 23 fixed to 21, and both ends of the cylinder 26 are rotatably connected to the tip of the lever 25 and the frame 5, and the cylinder 26 When the roll winding material A is pushed up to the above and a pressure is applied to the roll winding material A, and the cam 27 and the switch 28 which rotate together with the first gear 23 control the pressure so as to follow the decrease in the diameter of the roll winding material A, The rolled material A makes a light contact with the belt conveyor 3. Therefore, it is possible to prevent the material from being deformed.

Further, a lower arm 29 having a pivotal fulcrum at the end and a lower end of the lower arm 29 and the frame 5 so that the core rod a deviated from the tip of the upper arm 22 is transferred to the lower end of the guide rail 2. Both ends of the cylinder 31 are rotatably connected to each other, a roll winding material A having a small remaining amount is pushed up to the cylinder 31, and a sufficient pressure is applied to the cylinder 31, and the roll winding material A is operated by a cam and a switch like the upper arm 22. If the pressure is reduced by following the decrease in the diameter of, the same effect as described above can be obtained.

Immediately before the core a falls on the chute 9, the lower arm 29 escapes downward so that the cylinder 3
Reduce the pressure of 1.
