Abstract

A fiberboard splice apparatus is made up of a fiberboard splice part for adhering an old fiberboard fed from one roll fiberboard to an end portion of a new fiberboard fed from the other roll fiberboard to accomplish fiberboard splice therebetween, and a fiberboard feed device for forwarding the new fiberboard from the other roll fiberboard to the fiberboard splice part. The fiberboard feed device includes one fiberboard feed roll placed along an axial direction of the roll fiberboard to make the other roll fiberboard rotatable in a state brought into contact with a surface of the other roll fiberboard and a pair of pickup members located to interpose the fiberboard feed roll therebetween for picking up a tip portion of the other roll fiberboard while coming into sliding contact with the surface of the other roll fiberboard.

4. A fiberboard splice apparatus according to claim 1, further comprising pickup member rocking means for rocking said pickup members independently with respect to said fiberboard feed roll.

5. A fiberboard splice apparatus according to claim 4, wherein said pickup member rocking means includes a pickup member supporting member made rockable, a supporting member actuator for rocking said pickup member supporting member, and a controller for controlling said supporting member actuator.

6. A fiberboard splice apparatus according to claim 4, wherein said pickup member rocking means includes a fiberboard detection sensor for detecting a tip portion of the other roll fiberboard picked up by said pickup member.

7. A fiberboard splice apparatus according to claim 1, wherein said pickup member includes:

a finger having a function to pick up a tip portion of the other roll fiberboard and a function to guide said new fiberboard fed from the other roll fiberboard; and

a cutter having a function to pick up said tip portion of the other roll fiberboard and a function to cut a tape used for adhering said tip portion of the other roll fiberboard to a roll outer circumferential surface thereof.

8. A fiberboard splice apparatus according to claim 7, wherein said finger is constructed as a flat-plate-like member extending along a cross direction of the other roll fiberboard, and

said cutter is made so that its tip portion has a function to cut said tape and made to be movable in said cross direction of the other roll fiberboard.

9. A fiberboard splice apparatus according to claim 8, further comprising:

a fiberboard detection sensor for sensing a tip portion of the other roll fiberboard picked up by said pickup member;

a cutter actuator for shifting said cutter in a cross direction of the other roll fiberboard;

a fiberboard feed roll actuator for rotating said fiberboard feed roll; and

a controller for issuing a control signal for operating each of said cutter actuator and said fiberboard feed roll actuator,

said control means, when said fiberboard detection sensor senses the tip portion of said roll fiberboard, issuing a signal to said fiberboard feed roll actuator for stopping the rotation of said fiberboard feed roll and further issuing a signal to said cutter actuator to shift said cutter in a cross direction of the other roll fiberboard for cutting a tape used for adhering a tip portion of the other roll fiberboard to a roll outer circumferential surface thereof.

10. A fiberboard splice apparatus according to claim 1, further comprising:

a fiberboard feed roll actuator for rotationally driving said fiberboard feed roll; and

a clutch made to establish connection and disconnection of a driving force from said fiberboard feed roll actuator.

11. A fiberboard splice apparatus according to claim 1, further comprising:

a pair of roll supporting frames for supporting said fiberboard feed roll at their end portions; and

guide members fixedly secured to said roll supporting frames to guide, to said fiberboard splice part, the other roll fiberboard picked up by said pickup member.

12. A fiberboard splice apparatus according to claim 1, further comprising:

a tape detection sensor for detecting the presence of a tape used for adhering a tip portion of the other roll fiberboard to a roll outer circumferential surface thereof;

a fiberboard feed roll actuator for rotating said fiberboard feed roll; and

a controller for outputting a control signal for operating said fiberboard feed roll actuator,

said controller, when the presence of said tape is sensed by said tape detection sensor, driving said fiberboard feed roll actuator to set a rotational speed of said fiberboard feed roll at a value lower than a predetermined rotational speed.

13. A fiberboard splice apparatus according to claim 1, further comprising a fiberboard end processing device for cutting the new fiberboard, fed by said fiberboard feed device, by a predetermined length from its tip portion.

14. A fiberboard splice apparatus according to claim 1, further comprising a tape adhering device for adhering a pressure sensitive adhesive double coated tape onto an end portion of the new fiberboard.

15. A corrugate machine comprising a fiberboard splice apparatus according to claim 1.

16. A fiberboard splice apparatus comprising:

a fiberboard splice part for adhering an old fiberboard fed from one roll fiberboard to an end portion of a new fiberboard fed from the other roll fiberboard to accomplish fiberboard splice therebetween; and

a fiberboard feed device for forwarding said new fiberboard, fed by unrolling the other roll fiberboard, to said fiberboard splice part,

wherein said fiberboard feed device includes;

one fiberboard feed roll placed along an axial direction of the other roll fiberboard; and

a pair of pickup members disposed one on each side of said fiberboard feed roll for picking up a tip portion of the other roll fiberboard;

a fiberboard feed roll actuator for rotationally driving said fiberboard feed roll, and

a controller for controlling said fiberboard feed roll actuator,

said fiberboard feed roll being rotated by said fiberboard feed roll actuator in accordance with a control signal from said controller for fiberboard feeding in a state where said fiberboard feed roll and said pickup member are brought into contact with a surface of the other roll fiberboard.

17. A fiberboard feed method of feeding a new fiberboard to a fiberboard splice part for adhering an old fiberboard fed from one roll fiberboard to an end portion of said new fiberboard fed from the other roll fiberboard to accomplish fiberboard splice therebetween, said method comprising:

a first step of rocking one fiberboard feed roll and a pair of pickup members, disposed one on each side of said fiber board feed roll according to an unrolling direction of the other roll fiberboard and of rocking said pickup member independently of said fiberboard feed roll; and

a second step of picking up a tip portion of the other roll fiberboard to feed said tip portion to said fiberboard splice part while rotating the other roll fiberboard through the use of said fiberboard feed roll in a state where said fiberboard feed roll and said pickup member are brought into contact with a surface of the other roll fiberboard.

18. A fiberboard feed method according to claim 17, wherein said first step includes:

in a case in which the other roll fiberboard is in a face-winding condition in which fiberboard is wound in a state where its fiberboard face appears on an outer surface thereof bring said fiberboard feed roll into contact with a surface of the other roll fiberboard so that said fiberboard feed roll reaches a first position and bring said a tip portion of one of said pickup members into contact with said surface of the other roll fiberboard;

while

in the case in which the other roll fiberboard is in a back-winding condition in which fiberboard is wound in a state where its fiberboard back appears on an outer surface thereof, bring said fiberboard feed roll into contact with a surface of the other roll fiberboard so that said fiberboard feed roll reaches a second position different from said first position and bring a tip portion of the other pickup member into contact with said surface of the other roll fiberboard.

19. A fiberboard feed method according to claim 17, wherein said second step includes, in a state where the other roll fiberboard is picked up, cutting a tape used for adhering said tip portion of the other roll fiberboard to a roll outer circumferential surface thereof.
