[Prior Art] A paper core cutting machine generally includes a chucking device or a paper core driving device for driving a target paper core, uses a cutting core, and employs a disc blade system. In this method, with the cutting core inserted in the paper tube, the tip of the cutting core is gripped and driven by the chucking device together with the paper tube, the disc blade is cut into the paper tube, and the cutting operation is performed. Since it is equipped with a device or a paper tube driving device, it has a large target paper tube diameter and is applied to a relatively large machine. [Problems to be Solved by the Invention] However, a conventional paper core cutting machine generally includes a chucking device or a paper core driving device for driving a target paper core, has a complicated mechanism and operation, and can be automated. When the target paper tube diameter is complicated, it is relatively difficult to apply to a small machine. In order to solve these problems, the present invention adopts a method of receiving a paper tube on a pair of receiving rolls (or called underrolls) and rotating the paper tube by the rolls instead of the chucking device or the driving device. However, it is an object of the present invention to automate a series of operations from the supply, cutting and discharging of the target paper tube with a simple configuration. [Means for Solving the Problems] In order to achieve the above object, in the paper tube cutting machine of the present invention, a cutter is installed in parallel in the machine frame, and an inclined chute from the machine frame side position to the inner side is provided. The feed claw is pivotally supported at the inner end of the machine frame of the chute, a pair of receiving rolls is pivotally supported by the roll support rod near the lower part of the feed claw, and the support roll drive device is attached. Each roll can be driven in the same rotation direction, the roll support rod is rotated in advance according to the target paper tube to set the gap between the rolls, and the feed claw is rotated to move the paper tube. It is mounted and supported inside the same roll gap below the cutter, and the roll drive device drives the paper tube to rotate through the roll and allows the cutter to cut into and cut the paper tube. A stopper is pivotally provided on the machine frame adjacent to the receiving roll support bar, and when the roll support bar is rotated to the closed side of the roll interval, the rotation stop position of the support bar is moved by the stopper. After setting the gap between the rolls, after cutting the paper tube inside the gap, rotate the roll support rod to open the gap between the rolls larger than the diameter of the paper tube and receive the cut paper tube. It can be released to the lower part of the roll. Further, a reciprocating driving core device is continuously provided on the machine frame, and the core core can be inserted into and removed from the target paper tube supported in the receiving roll gap. The paper roll is driven to rotate by the receiving roll, the cutter is cut into the paper core, the cutting operation is performed, and after the paper core is cut, the cutting core can be removed from the paper core. Further, a roller-shaped pressing roll is pivotally provided on the machine frame above the receiving roll so that the target paper tube can be pressed in the upper space of the roll, and when the cutting core is inserted into the paper tube, the paper core and The eccentricity with the core is prevented, and the paper tube is pressed against the inside of the receiving roll gap to promote the rotational drive of the paper tube by the roll. Further, when a cutter sequential operation control device is attached to the cutter, the paper roll is rotationally driven by the receiving roll, and the cutter can be sequentially cut and cut from the side closer to the core center of the paper pipe. [Operation] In the paper core cutting machine configured as described above,
When the target paper tubes are fed in parallel on the chute, the paper tubes reach the inner end of the machine frame of the chute and are blocked by the convex part of the feed claw, but when the feed claw is rotated, the paper tube is fed. Only one piece is accommodated in the claw concave part and transferred along the concave part. In the vicinity of the lower part of the claw, the support rod of the receiving roll is set in advance according to the diameter of the target paper tube. The paper is fed and supported in the gap between the rolls, and at this time, the roll driving device drives the paper tube to rotate through the rolls and cuts and cuts the paper tube with the cutter. Further, a stopper is pivotally provided on the machine frame adjacent to the receiving roll support rod, and when the roll support rod is rotated to the closed side with the same roll interval, it is previously adjusted to the size of the paper tube diameter. Since the stopper determines the rotation stop position of the support rod and sets the gap between the rolls, the paper tube is supported in an appropriate inner position of the gap between the rolls, and the roll drive device rolls the paper tube through the rolls. And the cutter is cut into the paper core to perform the cutting operation, and after the cutting operation, the roll support rod is rotated to open the gap between the rolls to be larger than the diameter of the paper core, and to receive the cut paper core. Release to the bottom. Further, since the same core can be inserted into and removed from the target paper tube supported in the roll gap inside the roll core, the paper tube can be rotationally driven by the roll while the same core is inserted into the paper tube. The cutter is cut into the paper tube and the cutting operation is performed. After cutting the paper tube, the cutting core is released from the paper tube. Further, when the target roll is pressed by the pressure roll in the upper position of the roll gap, eccentricity between the roll core and the cut core is prevented and the cut core is smoothly inserted into the roll, and at the receiving roll gap. The paper core is pressed against the paper, and the rotation of the paper core is encouraged by the receiving roll.
Further, when a cutter sequential operation control device is attached to the cutter, the paper roll is rotationally driven by the receiving roll, and the cutter is sequentially cut and cut from the side closer to the cutting core base of the paper pipe. The cutter prevents the target paper tube from being displaced toward the base of the cutting core. [Embodiment] An embodiment will be described with reference to the drawings.
Cutters (2), (2), ... Are installed side by side on the machine frame (1), and an inclined chute (3) is installed from the machine frame side position to the inside, and the machine frame inner end of the chute is installed. The feed claw (4) is pivotally supported on the lower part, and a pair of receiving rolls (5),
(5) is pivotally supported by roll supporting rods (6) and (6), and roll driving devices (7) and (7) are attached to the supporting rods so that the respective rolls can be driven in the same rotation direction. , The roll support rod is set in advance according to the target paper tube (S) to set the gap between the rolls, and the feeding claw is rotated to bring the paper tube into the roll gap position below the cutter. It is supplied and supported, and the roll drive device drives the paper tube to rotate through the roll, and the cutter can cut into and cut the paper tube. Further, the receiving roll supporting rod (5),
Adjacent to (5), stoppers (8) and (8) are pivotally provided on the machine frame, and when the roll support rod is rotated toward the closed side of the roll interval, the roll support rod is supported by the stopper. Set the gap between the rolls by setting the rotation stop position of the roll, and after cutting the paper tube inside the gap, rotate the roll support rod to open the gap between the rolls and receive the cut paper tube. It can be released to the lower part of the roll. Further, a reciprocating driving core device (9) is continuously provided in the machine frame, and the core core (10) can be inserted into and removed from the target paper tube supported inside the receiving roll gap. When the paper roll is inserted into the paper core, the paper roll is rotationally driven by the receiving roll, a cutter is cut into the paper core to perform a cutting operation, and after the paper core is cut, the cutting core can be removed from the paper core. In addition, roller-shaped pressing rolls (11) and (11) are pivotally provided in the machine frame above the receiving roll, and the target paper tube can be pressed in the upper roll gap, and the cutting core (10) is provided. When it is inserted into the tube, the eccentricity between the paper tube and the cutting core is prevented, and the paper tube is pressed against the gap between the receiving rolls, so that the rotational driving of the paper tube by the roll can be promoted. Further, when a cutter sequential operation control device (not shown) is attached to the cutter, the paper roll is rotationally driven by the receiving roll, and the cutter can be sequentially cut and cut from a side closer to the core center of the paper pipe. There is. [Effects of the Invention] Since the present invention is configured as described above, it has the effects described below. When the target paper tubes are fed in parallel onto the chute, the paper tubes reach the inner end of the machine frame of the chute and are blocked by the convex parts of the feed claws. Only the books are transferred along the recesses of the feed claws, and they are securely separated one by one and fed and supported in the gap between the receiving rolls. At this time, the roll drive device drives the paper tubes to rotate through the rolls. In addition, the cutter can be cut into the paper tube and the cutting operation can be performed. In addition, a stopper adjacent to the receiving roll support bar sets a gap between the rolls in advance according to the size of the paper tube diameter, and the paper tube is supported inside the gap to cut the paper tube. After cutting the paper core, the roll support rod is rotated to open the gap between the rolls larger than the diameter of the paper core, and the cut paper core is discharged to the lower part of the roll. Can be applied accordingly. Also,
The cutting core is inserted into the target paper core supported in the gap between the rolls and the paper roll is driven to rotate by the receiving roll, so that the paper core rotates stably and the cutter cuts into the paper core to smoothly cut. You can take action. Further, when the target paper tube is pressed by the pressure roll in the upper space of the roll, the eccentricity between the paper tube and the cutting core can be prevented and the cutting core can be smoothly inserted into the same paper tube. The present invention can be applied even if the tube is slightly curved, and the paper tube is pressed against the clearance between the receiving rolls, so that the rotation of the paper tube by the receiving roll can be reliably performed. Furthermore, when the cutter sequential operation control device is attached to the cutter, the cutter is sequentially cut from the side closer to the core center of the paper tube to perform the cutting operation, and the cutter cutting operation moves the cutter core to the core center side of the target paper tube. Displacement can be prevented and the cut length of the paper tube can be accurately secured. It should be noted that instead of the chucking device or drive device in the conventional paper core cutting machine, a system is adopted in which the paper core is received and driven to rotate within the gap between the pair of receiving rolls.・ Since each operation from cutting to discharging can be performed by the simple configuration as described above, the series of paper tube cutting operations can be automated by a simple sequence control device and the length of the target paper tube can be increased. It can be applied to both large-sized machines and small-sized machines regardless of the size and the diameter of the paper tube.
