◎ Description of the tape feeder device As shown in Fig. 2, the guide rail 12-1 is fixed to the side surface of the suction box 6 in the longitudinal direction.
The tape feeder 12 is movably guided,
Servo motor 12-1 shown in FIGS. 5 to 7
It is driven to travel by 3. Servo motor 12-
The output shaft of No. 13 has a chain wheel 12-14 and a chain wheel 12-14 with a one-way clutch.
15 is installed, but the chain wheel 12
-14 is a drive source for running the tape feeder 12, and is a chain wheel 12 that rotates in only one direction.
-15 drives a top feed roller 12-16 which feeds out the adhesive tape base 11a. What is indicated by numerals 12-19 is a chain wheel 12.
This is a rotary encoder that detects the rotational status of -14 and 12-15.

The bottom feed rollers 12-17 are pressed against the top feed rollers 12-16 by an air cylinder (not shown), and an electromagnetic brake (not shown) is attached to the shaft of the top feed rollers 12-16. A mechanism is adopted in which the base 11a is strongly held by the feed roller when the motors 12-13 rotate in reverse, and the one-way clutch is fully operated.

Further, the upper and lower feed rollers are coated with rubber to prevent them from slipping against the base 11a.

This adhesive tape 11b is attached to the left side of the suction box in FIG.
1-2, tape cutter 11-3, pass rollers 11-4, 11-5, 11-6, etc., and the tape feeder 12 as shown in the pass line. 8 and 9 show a cutter adjustment device.

As described above, the double-sided adhesive tape 11 is held and pulled by the tape feeder 12 and fed out from the operation side to the transmission side, and the tape feeder 12 is provided with a photoelectric switch 12-18 to set the feed amount. Also, pass rollers 11-4 and 11-
A tape cutter 11-3 is provided between the tape cutter 11-3 and the tape cutter 11-3.

◎ Description of the tape cutter device Next, the details of the tape cutter device shown in FIGS. 8 and 9 will be described.
It is held by a swing lever 11-8 connected to 1, is pressed with appropriate nip pressure onto a Teflon plate 11-12 that serves as a pedestal, and is guided to a slide rail 11-14 by the operation of another air cylinder 11-13. Then slide the adhesive tape 11
Make a notch in b. The accuracy of this cut is an important point in the process of this automatic machine. Therefore, a structure is adopted in which the pressing force of the two score cutters 11-7 can be adjusted separately by using a spring 11-9 and an adjusting bolt 11-10 that can always apply a constant pressure to the adhesive tape 11b.

Also, the reason why two score cutters are used together is to increase the certainty of cutting.

◎ Explanation of the sheet cutter device Next, the tape feeder and sheet cutter device shown in Figures 6 and 7 will be explained.
The entire device is suspended on a guide rail 12-1 by a linear bearing case 12-2, and is pulled by a chain 12-3 and travels.

Sheet cutter 12-4 and press roll 12-5
are incorporated coaxially, and the guide roller 12
-6 together with the bracket 12-7,
It is guided by a ball spline 12-8 and raised and lowered by an air cylinder 12-9. A rubber sheet 5-34 is embedded in the surface of the suction drum 5 to prevent damage to the cutting edge of the sheet cutter 12-4 and to help bond the adhesive tape.

The guide roller 12-6 is made of Teflon material to improve peeling of the adhesive tape. The pressure roll 12-5 is coated with soft rubber, which improves the pressure bonding of the adhesive tape, improves the cushioning when the sheet cutter 12-4 cuts the web 4, and improves the compression sheet cut. Simultaneous machining begins to run smoothly.

◎ Explanation of the attachment mechanism of the adhesive tape 11b In Fig. 6, the base holder 12-10 is located above the guide roller 12-6, and the air cylinder 12-9 operates on the pressure side, so when this air pressure is released, the spring 12-11 pulls up the guide roller 12-6 etc. via the hanging bolt 12-12, holds the base 11a,
The double-sided adhesive tape 11 can be pulled to the right and positioned on the web width. At this time, the top feed rollers 12-16 are also rotated and the base 1
Send out 1a. At this time, in FIG. 6, there is no adhesive tape 11b on the right side of the pressure roll 12-5, and the tip of the adhesive tape 11b is positioned directly below the vertical line of the pressure roll 12-5. Next, the tape feeder is lowered and travels to the drive side end of the web 4, where it stops. As shown in FIGS. 5 and 6, the base 11a is connected to the feed roller 12-
16 and 12-17, the air cylinder 12-9 is pressurized, the adhesive tape 11b is adhered to the web 4, and in this state, the chain 12-
3, it reaches the 4th end of the web on the operation side and stops.

That is, the tip of the base 11a is reliably held by the feed rollers 12-16 and 12-17, which remain stationary.

As shown in FIG. 6, the clearance angle of the base 11a from the pressure roll 12-5 of the tape feeder 12 toward the guide roller 12-6 is approximately 32 degrees, and the adhesive tape 11b is pressed against the web 4 while moving toward the operation side. When the base 11a is pulled, it is separated from the adhesive tape 11b, and the pasting operation is performed while being squeezed. The above is the adhesive tape application mechanism.

◎ Effects of the splicing device according to this embodiment When the winding roll 3 wound on the winding drums 1 and 2 is wound to a predetermined length,
Stop the rotation of the drum. In this way, as the paper on the unwinding roll 8 is wound up into two or three sheets on the take-up roll 3, the web 4 becomes 4a in the case of upward pulling.
It reaches the line , and in the case of a downstroke, it reaches the line 4a'.

The suction drum was waiting below this line, but by operating the lifting motor 5-30, it was raised by the screw 5-24 and the web 4
It stops at the line of the web 4b while lifting it.

This position corresponds to the guide roller 12 in FIG.
-6 is separated from the base holder 12-10, the adhesive tape base 11a is released, the tape feeder 12 is in a state where it can run freely, and the sheet cutter 12-4 comes into contact with the web on the suction drum 5. A state in which no

The second suction chamber 5-2 of the suction drum 5 is vacuumed and the web 4 on the unwinding roll 8 side is
Even if d becomes slack, the tension of the winding web 4b is maintained.

In this state, the tape feeder 12 is run from the origin I to the origin J shown in FIG. 10, and is memorized by the attached photoelectric switch 12-18.

Next, the suction drum 5 is raised so that the web contacts the web 4E line, that is, the lower surface of the suction box 6. Of course, chain wheel 5-28 for overwork.
A safety device using a torque limiter is taken into consideration, and in addition to stopping the web line 4b, it can also be stopped by a signal based on the number of pulses from the rotary encoder 5-35 at the end of the interlocking shaft 5-21. The relative position of the web cutter 5-10 of the suction drum 5 and the suction box 6 is shown in FIG. Then run the cutter to cut the web.

Stop vacuuming the suction drum 5, take out the empty spool 7, and load a new roll.

Leave the web end of the new rewind roll 8 hanging slightly longer.

The suction drum 5 is lowered and rotates after a while.

In Fig. 2, the first intake chamber 5-1 is located at the lower left,
Turn about 225 degrees and contact the web at point R.

Since a vacuum is applied to the first intake chamber 5-1, a vacuum sensor (not shown, but installed in a fixed pipe) is activated at the same time as the suction, and the signal is sent to the elevator motor 5-30.
stops, and the suction drum 5 also stops descending at point R.

The suction drum 5 continues to rotate in the clockwise direction, and when the first intake chamber is closed by the front web, the vacuum sensor is activated, and its signal causes the motor 5-30 to stop and rotate in reverse. At the same time, the sheet cutter 12-4 continues to rise until it comes into contact with the web in response to a pulse signal from the rotary encoder 5-35, and stops at a position where it can properly cut the web.

Also, the pulse of the swing motor 5-19 is set so that the position at which the swing movement is stopped is maintained at the position shown in FIG. Stop.

When the above conditions are set, the tape feeder 12, which had been stopped at the origin J, travels to the origin I. During this time, the new web 4d is cut by the sheet cutter 12-4, and the width is cut by the photoelectric switch 12-18. The size and cross-sectional position are detected as described above, but the computer is made to calculate the amount of overlap between the old and new webs, and also indicates the travel distance.

This will be explained using an example shown in FIG.

C is the center line of the sheet cutter 11-3, B is the distance from origin I to C, D is the distance from origin I to origin J, X1, Y1, Z1 are the relative positions of the old and new webs,
X2, Y2, and Z2 are the positional relationships of the new webs, and M is the amount of overlap between the old and new webs, that is, the length of the adhesive tape 11b actually traveling and bonding.

Tape feeder 1 located at origin I as described above
2 has traveled to the origin J and stopped. During this time, the photoelectric switch 12-18 detects the cross-sectional positions (A) and (B), and reads the width Y2 of the new web 4d. The width dimension of the old web 4a being wound up on the winding roll 3 has already been stored in the computer by the above-mentioned means, and based on this data, the computer calculates the wrap amount M. Instructs the means of travel and the distance.

The base 11a is a feed roller 1 as shown in the figure.
It is sandwiched between 2-16 and 12-17 and sent together with the double-sided adhesive tape 11. Adhesive tape 11
It is assumed that the tip of b is always at the origin I. Air cylinder 1 of tape feeder 12
2-9 is operating, so tape feeder 12
The guide roller 12-6 on the right side of the base 11a
The guide roller 12-6 on the left side presses and holds the double-sided adhesive tape 11. In this state, the tape feeder 12 travels only m2.
Stop at position (c).

Next, the adhesive tape 11b is cut with a tape cutter 11-3 and a score cutter 11-7. Next, the tape feeder 12 travels a distance of m1 and stops at position (A). Now adhesive tape 1
1b is placed above and near the tip of the new web 4d that satisfies the wrap amount M.

Next, when the press roll 12-5 is pressed onto the base 11a of the double-sided adhesive tape 11 at the right end (A) position of the new web 4d by the air cylinder 12-9, the tip of the adhesive tape 11b will stick on one side. become.

In this state, move the pressure roll 12-5 to the old web 4E.
Rolling is carried out to the position of the already cut end face (d). At this time, the base 11a is lifted by the guide roller 12-6 on the right side, so that it separates from the adhesive tape 11b and moves away from the adhesive tape 11b, as shown in FIG.
1b is adhered to the new web 4d.

At the same time, the sheet cutter 12-4 disposed along the pressure roll 12-5 cuts the leading end portion of the new web 4d along the edge of the adhesive tape 11b.

Since the adhesive tape 11b has already been cut at position (D), the pressure roll 12-5 is not placed in the position.
When the double-sided adhesive tape 11 is stopped at (d) and raised by the air cylinder 12-9, the double-sided adhesive tape 11 is also lifted up and separated from the already bonded tape 11b.

The portion of the new web 4d where the difference E between X1 and X2 shown in FIG. 10 is not cut by the sheet cutter 12-4, but if the value of E is minimized, it will be substantially cut. Or sheet cutter 12-4
If it is fixed to the main body of the tape feeder 12 so that it does not have a disk shape and does not rotate, and the blade at the lower end is formed long into a knife shape along the adhesive tape, the new web 4d can be completely cut from start to finish. disconnected.

These controls are attached to the tape feeder 12, detecting the moving photoelectric switch 12-18, and transmitting its signal to the rotary encoder 12-18.
The entire process can be performed by computer processing using a combination of 19 pulses.

At this position, the air cylinder 12-9 of the tape feeder 12 is released and the bracket 12-7
Rise and wait. The base 11a is the holder 12
-10. The leading end of the new web 4d is cut by the sheet cutter 12-4, and although it was sucked into the first intake chamber 5-1, it is released and falls downward. The suction drum 5 turns about 45 degrees and stops.

The suction drum 5 is raised by the drum lift motor 5-30 to the web 4E line, that is, the line held by the old web, and the adhesive tape joins the new and old webs by its contact pressure.

The drum 5 descends to the web 4B line, rotates about 60 degrees so that the center of the rolling roller coincides with the joining point, and then rises to the web 4E line. The rolling pressure roller 5-11 is pressurized by the spring 5-9 and rolls on the joint portion of the web to strengthen the adhesive force.

The suction box 6 attracts the spliced web, and is slowly moved by a geared motor (not shown) installed separately to take up the slack in the web on the unwinding side. ), the web is stopped before it breaks.

With the above steps, the joining of the old and new webs is completed, and the machine starts the winding operation again.

This invention is not limited to the above embodiments, but
Other embodiments may be made within the scope of the invention as set forth in the claims.
