[0002]

2. Description of the Related Art A perforating apparatus for forming a predetermined opening in a band-shaped material such as filter tip paper in a cigarette is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 8-196257. It is configured such that it is guided to a laser processing machine while being conveyed at a speed, and the belt-shaped material is irradiated with pulsed laser light to perform a hole forming process. At this time, in order to secure a high-speed stable running of the strip material, a reserve chamber for drawing the strip material using negative pressure on the entrance side (supply mechanism side) and the exit side (winding mechanism side) of the transport path is provided.

The feeding mechanism and the winding mechanism of the strip in this type of opening apparatus are generally designed to form a conveying path for the strip and to realize a stable high-speed feeding. It is arranged side by side on both sides of the laser beam machine. However, when the strip material supply mechanism and the winding mechanism are arranged on both sides of the laser processing machine, it is unavoidable that the width of the entire apparatus is increased.

There were problems such as difficulty in grasping and managing it. SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has as its object to simplify the entire apparatus and improve operability, and to simplify the operation state of the apparatus. It is an object of the present invention to provide a belt-shaped hole opening device having a simple structure.

An air permeability measuring unit 8 for measuring is provided. Reference numeral 9 in the figure denotes a control screen (operation panel) having a touch panel structure, which is located above a transport path formed by the transport mechanism 4 and is provided to cover a front panel of the housing 1. It is arranged flush with the front cover so that it can be operated without opening.

FIG. 2 is a front view showing a traveling path (conveying path) of the tip paper P in the laser aperture device configured as described above. The configuration of the laser opening apparatus will be described in more detail with reference to FIG. 2. The tip paper P to be subjected to the opening processing is supplied by being wound around a reel (not shown).
It is mounted on the reel shaft 21 of the supply mechanism 2. The reel shaft 21 is rotationally driven by, for example, a belt 23 by a servo motor 22 disposed on the back side of the front panel, and rewinds the chip paper P, so that the chip paper P is moved to the first position. Transfer mechanism 4 through the reserve chamber 6

The supply speed of the tip paper P is controlled to be constant.

On the other hand, a reel shaft 31 of the winding mechanism 3 is driven to rotate by a servo motor 32 disposed on the back side of the front panel, for example, via a belt 33.

And the tip paper P discharged through the second reserve chamber 7 is sequentially and continuously wound. In the figure, reference numeral 34 denotes a tension roller for applying a predetermined tension to the belt 33. The servo motor 32 basically controls the rotation speed of the reel shaft 31 in accordance with the change in the winding diameter of the tip paper P, and controls the winding speed of the tip paper P to be constant.

Now, the first and second reserve chambers 6,
7, two guide plates 61, 61, 71, 71 each having the width of the tip paper P are arranged in parallel at a predetermined interval, and these guide plates 61, 61, 71,
The side surfaces of 71 (front and rear surfaces in the reserve chamber) are respectively closed by a panel plate (not shown), and a lower portion thereof is connected to a suction pump (not shown) to apply a negative pressure. These first and second reserve chambers 6 and 7 are positioned on the side of the supply mechanism 2 and the winding mechanism 3 and are vertically arranged on the front panel of the housing 1. Part of the transport path of the tip paper P supplied from the supply mechanism 2,
And a part of the conveyance path of the tip paper P drawn out to the winding mechanism 3. And each of these reserve rooms 6,
7 guides the tip paper P guided to the upper end openings thereof to the guide plates 61, 61, 7 by the negative pressure.
Along the inner wall surfaces of the first and the first 71, they are drawn into a U-shape.

A pair of guide rollers 62, 63, 72, 73 are provided at the upper end openings of the reserve chambers 6, 7, respectively.
Guided by 2, 63, 72, 73, each reserve room 6
(7) Each is smoothly drawn into. Therefore, the tip paper P is continuously transported from the supply mechanism 2 to the transport mechanism 4 via the first reserve chamber 6, and from the transport mechanism 4 to the winding mechanism 3 via the second reserve chamber 7. And are conveyed continuously.

At a position above each of the reserve chambers 6 (7), laser light is applied to a U-shaped curved bottom of the tip paper P drawn into the reserve chamber 6 (7) as described later. While irradiating and receiving the reflected light, the distance L from the change in the optical path length to the U-shaped curved bottom portion,
Further, a laser length measuring device 64 (74) for measuring the length of the tip paper P drawn into the reserve chamber 6 (7) is provided.

The transport mechanism 4 to which the tip paper P is continuously supplied via the first reserve chamber 6 described above.
Is provided with first and second guide rollers 41 and 42 for transporting the tip paper P toward the laser processing machine 5 disposed on the side of the housing 1 and is disposed on the laser processing machine 5 side. Third to sixth guide rollers 43, 44, 45,
46, and these guide rollers 43, 44, 45, 46
7th and 8th guide rollers 47, 48 for transporting the tip paper P, which is returned from the laser processing machine 5 side via the laser processing machine 5 and conveyed, toward the second reserve chamber 7.
And a drive roller 49 for transporting the tip paper P at a constant speed. In particular, the drive roller 49 is a chip paper P formed by the guide rollers 41 and 48.
Is disposed at the most downstream position of the transfer path, and by driving the transfer while pulling the tip paper P on the transfer path,
The tip paper P travels at a constant speed over the entire stroke without causing slack in the middle of the transport path.

The second and third guide rollers 4
Reference numeral 2 and 43 denote a first for horizontally transporting the tip paper P to a laser beam irradiation area (a hole processing section) in the laser processing machine 5.
Of the transport path. The tip paper P that has passed through the laser beam irradiation area is transported downward through the third guide roller 43, and then further changed from the fourth guide roller 44 to the fifth and sixth guide rollers. The transfer direction is changed via the transfer rollers 45 and 46, so that the transfer direction is reversed and the transfer direction is turned back to the transfer mechanism 4 side. At this time, the third to sixth guide rollers 4
The second transport path formed by 3, 44, 45, and 46 plays a role of cooling the tip paper P that has been subjected to the opening processing by the laser beam.

The seventh and eighth guide rollers 4
The above-described air permeability measurement unit 8 is provided in the middle of the transport path formed by the reference numerals 7 and 48. For example, when the tip paper P is sucked from the lower surface side, the air permeability meter side portion 8 captures the amount of air sucked through the opening formed by the laser processing machine 5 as a change in the suction force. , And measures the air permeability depending on the opening diameter and the opening pattern. The accuracy (quality) of the hole processed by the laser processing machine 5 is monitored by the air permeability meter.

The laser processing machine 5 will be briefly described. This laser processing machine 5 comprises, for example, four laser aperture heads 51a, 51b, 51c arranged at a predetermined interval in the conveying direction of the tip paper P. , 51d. Each of these laser aperture heads 51a, 51b, 51
The positions c and 51d are provided so as to be position-adjustable in the width direction of the chip paper P, so that the irradiation position of the laser light can be changed in the width direction of the chip paper P. Thus, each laser aperture head 51a, 51b, 5
1c and 51d are each driven at a predetermined timing in conjunction with the transport of the tip paper P, and form a fine opening of a predetermined diameter in the tip paper P by irradiating a pulse laser beam.

Each of the laser aperture heads 51a, 5
1b, 51c and 51d, and the position of each laser aperture head 51
a, 51b, 51c, 51d, by adjusting the irradiation timing of the pulsed laser light, the tip paper P continuously conveyed at a constant speed, for example, in a two-row staggered pattern. A plurality of apertures are sequentially formed.

Thus, according to the laser opening apparatus configured as described above, the supply mechanism 2 and the take-up mechanism 3 are arranged one above the other, and the transport mechanism 4 positioned on the side of the supply mechanism 2 is separated from the supply mechanism 4. After the supplied tip paper P is continuously conveyed at high speed toward the laser processing machine 5 on the side thereof, the conveying direction is turned back and conveyed to the winding device 3 side, so that the lateral width of the entire apparatus is reduced. As a result, a compact configuration can be obtained. Moreover, since the supply mechanism 2 and the winding mechanism 3 are arranged side by side vertically, the work of attaching and detaching the reel to and from the supply mechanism 2 and the winding mechanism 3 is easy.

Accordingly, after the reel on which the opening of the tip paper P has been wound has been removed from the winding mechanism 3, the reel which has been emptied after the supply of the tip paper P has been wound off from the feeding mechanism 2. The work of transferring to the mechanism 3 can be easily executed. Then, since new chip paper P may be attached to the supply mechanism 2, it is not necessary for an operator to go back and forth between the supply mechanism and the take-up mechanism with the laser processing machine interposed therebetween as in the related art. Effects such as shortening the paper P replacement work time and efficient operation of the hole opening device can be obtained.

Here, the roles of the first and second reserve chambers 6 and 7 described above, and the laser length measuring devices 64 and 64 provided above the first and second reserve chambers 6 and 7 respectively.
3 will be described in detail with reference to FIG. 3. The reserve chamber 6 into which the tip paper P is drawn in a U-shape is described.
(7) functions as a buffer mechanism (buffer) for preventing interference between the supply mechanism 2 (the winding mechanism 3) and the transport mechanism 4. That is, the reserve chamber 6 (7) draws the tip paper P in a U-shape by a predetermined negative pressure applied to the chamber, and the transport mechanism 4 that transports the tip paper P at a constant speed.
When the supply speed of the tip paper P continuously supplied from the supply mechanism 2 or the take-up speed of the tip paper P continuously taken up by the take-up mechanism 3 changes, according to the speed difference. Retraction amount of chip paper P (retraction length)
By changing the speed, the difference between the speeds is absorbed.

The reserve chamber 6 (7) is provided with a pair of guide panels 61, opposing each other at a predetermined distance d.
It is configured such that the tip paper P is drawn in a U-shape between 61 (71, 71). The laser length measuring device 64 (74) arranged above the reserve chamber 6 (7) has a U-shaped curved bottom of the tip paper P drawn into the reserve chamber 6 (7) for distance measurement. A laser beam is irradiated, and a distance L from the light receiving timing of the reflected light to the curved bottom portion is calculated as follows:
It is detected as the length of the tip paper P drawn into the reserve chamber 6 (7).

The drawing length (distance L) of the tip paper P detected by such a laser length measuring device 64 (74).
Is connected to the supply mechanism 2 via a preamplifier 65 (75).
It is provided to the servo controller 25 (35) of the (winding mechanism 3) and used for controlling the rotation speed of the servo motor 22 (32). Specifically, when the length of the tip paper P drawn into the reserve chamber 6 increases, the servo controller 25 of the supply mechanism 2 compares the tip paper P with the transport speed of the tip paper P by the transport mechanism 4. 2 that the supply speed of the tip paper P from the servo motor 22 is high.
When the length of the tip paper P drawn into the reserve chamber 6 is reduced, the transport mechanism 4
Feeding mechanism 2 in comparison with the transport speed of the tip paper P by
The control for increasing the rotation speed of the servo motor 22 is performed assuming that the supply speed of the tip paper P from the printer is low. Basically, by controlling the speed of the servo motor 22 to keep the length of the tip paper P drawn into the reserve chamber 6 constant, the supply speed of the tip paper P from the supply mechanism 2 fluctuates. Regardless, the transport of the tip paper P in the transport mechanism 4 at a constant speed is realized.

Similarly, the servo controller 3 of the winding mechanism 3
5 is a tip paper P drawn into the reserve chamber 7
Is longer, the rotation speed of the servo motor 32 is increased, assuming that the winding speed of the tip paper P in the winding mechanism 3 is slower than the feeding speed of the tip paper P by the feeding mechanism 4. When the length of the tip paper P drawn into the reserve chamber 7 is reduced, the servo is determined on the assumption that the winding speed of the tip paper P by the winding mechanism 3 is faster than the transport speed of the tip paper P by the transport mechanism 4. Control for reducing the rotation speed of the motor 32 is executed. Basically, the servo motor 32 is used to keep the length of the tip paper P drawn into the reserve chamber 7 constant.
By performing the speed control described above, the transport of the tip paper P at the transport mechanism 4 at a constant speed is realized irrespective of fluctuations in the winding speed of the tip paper P in the winding mechanism 3.

The transfer mechanism 4 is provided with the reserve chambers 6 and 7 functioning as described above at the supply end and the discharge end, respectively, thereby causing interference with the supply mechanism 2 and the winding mechanism 3. The chip paper P is driven at high speed at a constant speed. Also, within a variable permissible range of the retraction length of the tip paper P in the reserve chambers 6 and 7, high-speed transport start-up of the tip paper P and its fall can be realized.

At this time, the laser length measuring device 64 (74) can detect a change in the drawing length of the tip paper P in each of the reserve chambers 6 and 7 in real time (at a high speed) and with high accuracy. The servo motor 22 (32) in the (winding mechanism 3) can be operated with good control responsiveness. Therefore, the transport mechanism 4 is operated to operate the tip paper P
When the high-speed transfer of the paper is started, if the drawing length of the tip paper P in the reserve chamber 6 is shortened accordingly, this phenomenon can be quickly detected and the supply mechanism 2 can be started up with good responsiveness. , The winding mechanism 3 can be started up with good responsiveness by quickly detecting an increase in the drawing length of the chip paper P.

As a result, the high speed conveyance of the chip paper P is
Since it is possible to start up quickly and the supply mechanism 2 and the winding mechanism 3 respond at high speed, the tip paper P
In addition, it is possible to prevent accidents such as breakage of the tip paper P due to an undesired tension being applied. Incidentally, in the conventional system in which the retraction length of the tip paper P is detected from the pressure change in the pressure detection chamber communicating with the reserve chamber, a slight response to the pressure change itself which responds to the change in the retraction length of the tip paper P is provided. It is unavoidable that there is a delay, and it is necessary to convert the pressure change into a pull-in length via a conversion table. Therefore, as compared with this type of conventional method, the laser length measuring device 64 as described above is used.
According to the method of detecting the drawing length of the tip paper P in the reserve chamber 6 (7) using (74), it can be said that the responsiveness can be easily increased and highly accurate control can be realized.
Further, compared with the conventional method, it is not necessary to detect the pressure change while controlling the negative pressure applied to the reserve chamber with high accuracy. For example, the first and second reserve chambers 6 and 7 are provided with a common suction system. Since it is also possible to collectively use the suction device to perform suction, there is also an effect that the configuration of the suction system can be greatly simplified.

By the way, in the present apparatus in which a predetermined opening is formed in the laser processing machine 5 while continuously transporting the tip paper P at a high speed as described above. As shown in FIG. 2, static eliminators 10 are provided on the downstream sides of the reserve chambers 6 and 7, respectively. Each of these static eliminators 10
For example, as shown in FIG. 4, a conductive brush 10b is planted on the base 10a, and the brush 10b is grounded. Each of the static eliminators 10 is provided with the brush 10 on the surface of the tip paper P which is conveyed and driven as described above.
b, and has a role of discharging static electricity accumulated in the tip paper P to the ground line. Note that the static eliminator 10 is a non-contact type that generates ions having a polarity opposite to that of static electricity by using, for example, corona discharge, thereby canceling static electricity accumulated on the tip paper P. Is also good.

According to the apparatus in which the static eliminator 10 is incorporated, the installation environment of the apparatus is supposed to be dry, and the tip paper P and the reserve chamber 6, which are driven at high speed, are driven.
Even if static electricity is generated due to the contact friction caused by sliding contact with the guide panels 61 and 71 of 7, the static electricity is quickly accumulated by the static electricity removing device 10 without being accumulated in the tip paper P. In particular, in the present apparatus that forms the transport path as described above, the places where static electricity is most likely to occur are the reserve chambers 6 and 7, and at a position close to the location where the static electricity is generated, particularly downstream of the tip paper P in the transport direction. Since the static electricity accumulated in the chip paper P is quickly removed by the arranged static electricity removing device 10, it is possible to effectively prevent the adverse effect of the static electricity from spreading to the whole.

As a result, it is possible to prevent the tip paper P from being wound around the guide roller or the like due to the static electricity accumulated in the tip paper P on the downstream side of the reserve chamber 6, and the transport mechanism 4 is formed. It is possible to effectively prevent the adverse effects of the static electricity from affecting the entire process of the transport path. Therefore, it is possible to prevent a breakage accident due to the winding of the tip paper P around the guide roller or the like beforehand, assure the stable running of the tip paper P at a high speed, and to enhance the processing production efficiency. On the downstream side of the reserve chamber 7, it is possible to prevent problems such as irregular winding of the tip paper P in the winding mechanism 3. Further, when the tip paper P wound on the take-up reel is removed from the take-up mechanism 3, there is an effect that there is no fear that the operator may feel uncomfortable due to the generation of electrostatic spark. In particular, with a simple configuration in which the static eliminator 10 is provided downstream of each of the reserve chambers 6 and 7, it is possible to effectively solve the problem of static electricity that may be accumulated in the chip paper P. Say,
A great effect can be obtained in practical use.

Then, the control unit 11 operates the hole opening control unit in conjunction with the conveyance of the chip paper P, and drives the laser oscillator incorporated in the laser processing machine 5, thereby opening the hole in the chip paper P as described later. Is formed to oscillate and output a laser beam.

An end detector 15 and a brake mechanism 16 are incorporated in the transport mechanism 4 along the transport path. For example, when the end detector 15 detects breakage of the tip paper P, the brake mechanism 16 To stop the conveyance of the chip paper P promptly, and at the same time, stop the operation of the laser beam machine 5. Such control is also entrusted to the control unit 11.

Used for monitoring the processing quality. That is, from the information on the air permeability displayed on the execution screens B and C, the processing status of the opening by the laser processing machine 5 is monitored.

By the way, the laser aperture device is operated while selectively displaying such execution screens B and C, and the aperture is formed by the laser processing machine 5 while continuously transporting the tip paper P. [Referenc] in the execution screens B and C
