BACKGROUND OF THE INVENTION
The present invention relates to a post-processing apparatus for a used web roll when replacing a web roll of a wrapping paper or chip paper used for manufacturing a filter cigarette.
[0002]
[Prior art]
With the increase in the speed of the hoisting machine for producing cigarettes, the consumption speed of the web fed from the web roll increases, and the web roll needs to be replaced frequently. For this reason, this type of hoisting machine is equipped with a web roll roll exchange connecting device, and the roll exchange connecting device can continuously supply the web. More specifically, when the remaining amount of the web roll in use is reduced to a predetermined amount, the roll exchange connecting device switches the web feeding to a new web roll that is on standby, and then winds up the used web roll. It is removed from the machine and replaced with a new web roll.
[0003]
By the way, since the web always remains in the used web roll removed by the roll connection exchange device, the used web roll is used in order to reuse the core of the used web roll. A post-processing operation for separating the core into the remaining web is required.
[0004]
[Problems to be solved by the invention]
In the above-described post-processing operation, the remaining web is easily separated because its leading end is a free end, and since the end is bonded to the core, the remaining web is separated from the core without breaking. Is not easy. Therefore, post-processing work of the spent web roll is not to rely on manual, fully automated roll-switched connection device is difficult and Tsu Do not.
[0005]
The present invention has been made on the basis of the above-mentioned circumstances, and its object is suitable for achieving full automation of the roll exchanging and connecting device, and the remaining web and the core of the used web roll can be reliably and easily provided. An object of the present invention is to provide an aftertreatment device for a used web roll which can be separated.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the post-processing apparatus of the used web roll according to the first aspect of the present invention has an expansion receiving port that is expanded upward at an upper portion and extends from the expansion receiving port. Hold the used web in a horizontal position while holding the used web from the inside of the winding core above the collection path with the air duct and the expansion receptacle, and hold the tip of the remaining web that hangs down from the used web. An inner chuck that can be moved up and down that is guided into the expansion receiving port, and an air flow is generated in the air feeding pipe, and the remaining web guided into the expansion receiving port is blown through the air feeding pipe, so that the winding core Provided with an air feeding means for unwinding the remaining web and a shutter that is provided at a portion of the air duct on the side of the expansion receiving port and that can open and close the air duct, and adheres the end of the remaining web to the core. after the remaining web has melted from the winding core, leaving, shut other remaining web closes the aeolian conduit Temporarily fasten in the air feed conduit, and in this temporarily secured state, the inner chuck rises with the core and peels off the bond between the core and the end of the remaining web. Open the temporary stop.
[0007]
According to the above-described post-processing apparatus, when the used web roll is held in the horizontal posture by the inner chuck above the receiving opening of the collection path, the remaining web wound around the core is The tip hangs down and is guided to the expansion receptacle. On the other hand, since the airflow in the air duct that is connected to the expansion receiving port generates a suction flow from the expansion receiving port to the air feeding conduit, the tip of the remaining web guided into the expansion receiving port Is immediately sucked into the air duct. Therefore, the remaining web of the used web roll is continuously unwound, and the remaining web that has been unwound is blown through the air duct.
[0008]
Even if the remaining web is completely unwound, the end of the remaining web is bonded to the winding core, so that the remaining web extends from the winding core into the air duct through the expansion receiving port. In this state, the shutter closes and the aeolian conduit, residual web at between the inner surface of the shutter and aeolian conduit is sandwiched been made temporarily fixed residual web 71 then core is the inner chuck When lifted together, the end of the remaining web is peeled off from the winding core. As a result, the remaining web becomes free from the winding core and is blown in the air feed conduit.
[0009]
Preferably, the inner chuck is attached to the tip of the multi-axis robot arm, and its posture can be arbitrarily changed.
The used web roll post-processing apparatus according to a second aspect of the present invention further includes a plurality of air nozzles for generating an air flow toward the air feed pipe in the expansion receiving port. Such air flow helps guide the tip of the remaining web into the air duct.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, there is shown a used web roll aftertreatment device applied to a hoist for producing cigarettes. This post-processing apparatus includes a box-shaped frame 2, and an expansion receiving port 4 is provided in an upper portion of the frame 2. The expansion receiving port 4 has an inverted quadrangular truncated pyramid shape opened upward, and has a flange 6 at the upper end thereof. The expansion receiving port 4 has a flange 6 locked to the periphery of the frame 2, and a lower end portion supported by the frame 2 via a support shelf 8. More specifically, the support shelf 8 partitions the inside of the frame 2 up and down, and has a mounting opening into which the lower end of the expansion receiving port 4 is inserted.
[0011]
The lower end of the expansion receiving port 4 is connected to an air supply line 5, and the air supply line 5 has a cylindrical connection pipe 10 at an upstream end thereof. The connection pipe 10 is attached to the lower surface of the support shelf 8 coaxially with the expansion receiving port 4, and the lower end of the expansion receiving port 4 enters the connection pipe 10. The connecting pipe 10 is supported by the frame 2 via the holder plate 12.
[0012]
The upper end of the suction pipe 14 is connected to the lower end of the connection pipe 10, and the flexible air feed tube 16 is connected to the lower end of the suction pipe 14. The air feeding tube 16 extends to a web collection box (not shown) and is connected to the web collection box.
A connector 18 protrudes from the outer surface of the intermediate portion of the suction pipe 14, and the outer end of the connector 18 is connected to the blower 20 through the tube. The inner end of the connector 18 is connected to one end of a venturi tube portion 15 built in the suction tube 14, and the other end of the venturi tube portion 15 opens into the air feeding tube 16 at the lower end of the suction tube 14. The throat of the venturi tube portion 15 communicates with the suction tube 14. Therefore, when air is supplied from the blower 20 via the connector 18, the air is jetted into the air feeding tube 16 through the venturi pipe portion 15, and an air flow toward the web collection box is generated in the air feeding tube 16. Further, the air flow flowing through the venturi section 15 and the I remote in the suction pipe 14 in the flared socket 4 a negative pressure, the negative pressure through the connecting pipe 10 and the suction tube 14 from expanding socket within 4 aeolian An air flow toward the tube 16 is generated.
[0013]
Furthermore, the connecting pipe 10 is provided with a shutter plate 22 that can open and close its internal passage. The shutter plate 22 is located in the vicinity of the lower end of the expansion receiving port 4 and is reciprocated in a direction crossing the connecting pipe 10 by the expansion and contraction of the air cylinder 24. The air cylinder 24 is supported by the frame 2, and a guide groove 26 for guiding the reciprocation of the shutter plate 22 is formed on the inner surface of the connection pipe 10.
[0014]
On the other hand, four air nozzles 28 are provided in the expansion receiving port 4, and these air nozzles 28 are connected to the blower 20 described above via a tube. As is clear from FIG. 2, the air nozzles 28 are respectively disposed at the corners of the widening receiving port 4, and their tips open toward two inclined surfaces of the widening receiving port 4 facing each other. Therefore, the air ejected from the air nozzle 28 flows along the slope of the widening receiving port 4 toward the air duct 5, that is, the connecting pipe 10.
[0015]
As shown in FIG. 1, an inner chuck 30 can be disposed above the expansion receiving port 4. The inner chuck 30 is attached to the hand of a multi-axis robot arm and can be opened and closed. The chuck claw 32 is provided. The hand of the robot arm is provided with an outer chuck (not shown) in addition to the inner chuck 30. More specifically, the robot arm, the inner chuck 30 and the outer chuck constitute a part of a roll exchange connecting device for a web roll for feeding the web, and the inner chuck 30 and the outer chuck can be moved up and down via the robot arm. It is possible to move in any direction of front, back, left and right, and these postures can also be arbitrarily changed via the hand.
[0016]
Specifically, the inner chuck 30 is that the chuck claws 32 engaged from inside the core C of the new goods web roll NR (see two-dot chain line in FIG. 1) to grip the web roll NR, and, Used to mount the gripped web roll NR on a hoist. The core C is made of a synthetic resin.
On the other hand, the outer chuck grips the remaining web W of the used web roll WR from the outside, removes the used web roll WR from the hoisting machine, and removes the used web roll WR while holding it in a vertical posture. Used to transfer to position.
[0017]
Thereafter, the inner chuck 30 can be engaged with the core C of the used web roll WR from the inside at the holding position, and can grip the used web roll WR.
When the used web roll WR held by the inner chuck 30 is transferred from the hoisting machine toward the above-described post-processing apparatus, the inner chuck 30 maintains the used web roll WR in a vertical posture. The remaining web W is prevented from unraveling from the finished web roll WR.
[0018]
After this, when the used web roll WR together with the inner chuck 30 reaches above the expansion receiving port 4 in the post-processing apparatus, the inner chuck 30 changes its posture and holds the used web roll WR in a horizontal state. Then, as shown in FIG. 1, it is lowered so as to be positioned immediately above the expansion receiving port 4. Therefore, the tip of the remaining web W unwound from the used web roll WR is reliably guided into the expansion receiving port 4.
[0019]
On the other hand, when the lowering of the inner chuck 30 is started, the blower 20 supplies the compressed air to the venturi pipe portion 15 of the suction pipe 14 and the air nozzle 28. As a result, the air nozzle 28 is expanded and received as described above. An air flow is generated from the inside of the mouth 4 toward the air duct 5 , that is, the connecting pipe 10, while the venturi pipe portion 15 sucks air from the expansion receiving port 4 through the connecting pipe 10 into the suction pipe 14, and Then, an airflow is generated that flows in the air feeding tube 16 toward the web collection box.
[0020]
Thus, while the tip of the remaining web W guided into expansion socket 4 is guided toward the lower end of the expansion socket 4 without being caught on the inner surface of the expansion socket 4 by the air flow from the air nozzles 28, The air is reliably drawn into the suction pipe 14 through the connecting pipe 10 and is blown toward the web collection box through the blower tube 16.
Therefore, the remaining web W is smoothly unwound and is drawn into the air-feeding tube 16 from the expansion receiving port 4 through the connection pipe 10 and the suction pipe 14, and continuously winds toward the web collection box. Sent.
[0021]
Thereafter, even if the remaining web W is completely unwound, the end of the remaining web W is bonded to the core C of the used web roll WR, so that the remaining web W is completely extended without being separated from the core C. It will be in the state of taking out.
In this state, when the shutter plate 22 closes the connecting pipe 10, the shutter plate 22 sandwiches the remaining web W between the inner surface of the connecting pipe 10 and temporarily fixes it. Is raised by a predetermined distance. Such a rise of the winding core C tends to lift the remaining web W upward. However, since the remaining web W is temporarily fixed by the shutter plate 22, the end of the remaining web W and the winding core C are not fixed. The adhesion between them is peeled off, and the remaining web W is completely separated from the core C. Here, since the temporary fixing of the remaining web W is performed in the connecting pipe 10, the length from the temporary fixing position to the end of the remaining web W is short, and when the winding core C is raised, the winding core C is temporarily fixed. The remaining web W is not broken between the positions.
[0022]
Thereafter, when the shutter plate 22 opens the connecting pipe 10 and releases the temporary fixing of the remaining web W, the remaining web W becomes free, and the entire web is blown through the blower tube 16 and collected in the web collection box. . When all of the remaining web W is collected in the web collection box, the operation of the blower 20 is stopped.
On the other hand, the core C held by the inner chuck 30 is transferred by a robot arm to a core recovery box (not shown) and recovered in the core recovery box.
[0023]
Since the inner chuck 30 constitutes a part of the roll exchange connecting device as described above, the separation of the remaining web W and the core C of the used web roll WR from the exchange of the web roll and the recovery thereof are performed. The steps up to and including the post-treatment can be completely automated.
The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in one embodiment, a venturi pipe portion 15 is provided in the air duct 5 to generate an air flow in the air duct 5, but a suction source is connected to the downstream end of the air duct 5. Then, an air flow may be generated.
[0024]
Moreover, in one Embodiment, although the expansion receptacle 4 becomes a reverse quadrangular frustum shape, a reverse frustum shape may be sufficient.
Further, the inner chuck 30 does not necessarily have to be attached to the hand of the robot arm in the roll exchanging and connecting device, and may be anything as long as it can receive the used web roll WR and move up and down.
[0025]
【The invention's effect】
As explained above, according to the used web roll post-processing apparatus of the present invention according to claim 1, the used web roll held by the inner chuck is disposed above the expansion receiving port. The remaining web that has been unwound from the web roll is reliably guided to the expansion receiving port, and is then blown through the air duct so that the remaining web can be recovered while being smoothly unwound. Then, after the remaining web is completely unwound, the remaining web is temporarily fixed with a shutter, and the core of the used web roll is lifted by the inner chuck, so that the core is bonded to the end of the remaining web. Is reliably peeled off, allowing complete separation between the core and the remaining web, which can be collected separately. Therefore, it is possible to completely automate the process from the replacement of the web roll to the separation and collection of the remaining web and the core in the used web roll, that is, the subsequent processing.
[0026]
According to the post-processing apparatus of the present invention according to claim 2, since the air nozzle is provided in the expansion receiving port, the tip of the remaining web can be reliably guided into the air duct by the air flow from the air nozzle. .
