(2) manufacturing installation of absorbent commodity
Below, the manufacturing installation 100 of the absorbent commodity 1 of embodiment is described.Fig. 2 is the diagram of the manufacturing installation 100 of expression embodiment.
As shown in Figure 2, manufacturing installation 100 has: a pair of conveying roller 110 (conveying roller 110A and conveying roller 110B), rotary body 120, a plurality of ultrasonic unit 130 (ultrasonic unit 130A and ultrasonic unit 130B), wobble drive portion 140, swing arm 150, linking arm 160 and guide part 170.
Conveying roller 110 is rotated centered by rotating shaft 111, and extend with the crisscross CD that throughput direction MD intersects on these rotating shaft 111 edges.Conveying roller 110 for example is columned cylinder.Conveying roller 110 is along with the rotation of conveying roller 110 is carried fabric 100W along throughput direction MD.
Fabric 100W is by constituting with front waist 10, back lumbar part 20 and with the corresponding fabric of lower crosspiece part.In addition, in embodiment, in the stage that is directed to ultrasonic unit 130, peristome 40 has formed.
Specifically, conveying roller 110A is rotated centered by the rotating shaft 111A that extends along crisscross CD.Conveying roller 110B is rotated centered by the rotating shaft 111B that extends along crisscross CD.
Here, the rotary speed of conveying roller 110A and conveying roller 110B is preferably variable.That is, the transporting velocity of fabric 100W is preferably variable.In detail, conveying roller 110A and conveying roller 110B preferably constitute, by the rotary speed of periodic variation conveying roller 110A and conveying roller 110B, thus the transporting velocity of periodic variation fabric 100W.
Rotary body 120 is rotated centered by the rotating shaft 121 that extends along crisscross CD.Rotary body 120 has the outer peripheral face 122 that contacts with fabric 100W along throughput direction MD at assigned position P.Rotary body 120 for example is columned cylinder.Rotary body 120 has seal edge portion 123 and heater 124.
Seal edge portion 123 is located on the outer peripheral face 122 of rotary body 120.Seal edge portion 123 has the edge sealing pattern that forms junction surface 50 usefulness.The edge sealing pattern is for example by radially constituting from outer peripheral face 122 outstanding a plurality of projections at rotary body 120.
Heater 124 rises the temperature of the seal edge portion 123 on the outer peripheral face 122 that is located at rotary body 120.Heater 124 is in the inboard that is arranged radially in seal edge portion 123 of rotary body 120.Heater 124 is preferably adjacent with seal edge portion 123.
Ultrasonic unit 130 is the devices that produce ultrasonic vibration.Ultrasonic unit 130 upward forms junction surface 50 by ultrasonic vibration being applied to the fabric 100W that is sandwiched between rotary body 120 (seal edge portion 123) and the ultrasonic unit 130.
In embodiment, a plurality of ultrasonic units 130 (ultrasonic unit 130A and ultrasonic unit 130B) carry out edge sealing to the same area on the fabric 100W.Ultrasonic unit 130A and ultrasonic unit 130B are along throughput direction MD and row arrangement.
Here, because ultrasonic unit 130A and ultrasonic unit 130B have identical structure, therefore, for the detailed construction of ultrasonic unit 130, be that example describes with ultrasonic unit 130A.
Ultrasonic unit 130A has transducer 131, amplifier 132, ultrasonic horn 133 and automatic regulating apparatus 134.
Transducer 131 produces ultrasonic vibration according to the signal of telecommunication.Transducer 131 is connected with amplifier 132.
The ultrasonic vibration that 132 pairs of transducers 131 of amplifier produce is amplified.Amplifier 132 is connected with ultrasonic horn 133.
Ultrasonic horn 133 utilizes by the ultrasonic vibration after amplifier 132 amplifications and vibrates.The top of ultrasonic horn 133 is located on the position corresponding with rotary body 120 outer peripheral faces 122 at assigned position P.
Thus, along with the rotation of rotary body 120, sandwiched at assigned position P fabric 100W between the top of seal edge portion 123 and ultrasonic horn 133.In addition, utilize the vibration of ultrasonic horn 133 and welding fabric 100W.Thus, form junction surface 50.
Automatic regulating apparatus 134 is maintained in predetermined distance with the interval (interval R shown in Figure 3) of the outer peripheral face 122 of the top of ultrasonic horn 133 and rotary body 120.
Specifically, when between the top that is sandwiched seal edge portion 123 and ultrasonic horn 133 at assigned position P fabric 100W, 134 pairs of automatic regulating apparatuses detect the stress that ultrasonic horn 133 is pressed into seal edge portion 123, and the interval of the outer peripheral face 122 of the top of ultrasonic horn 133 and rotary body 120 is controlled to detected stress for certain.
Perhaps, when between the top that is sandwiched seal edge portion 123 and ultrasonic horn 133 at assigned position P fabric 100W, the counteracting force of the seal edge portion 123 that 134 pairs of ultrasonic horns 133 of automatic regulating apparatus are subjected to detects, and the interval of the outer peripheral face 122 of the top of ultrasonic horn 133 and rotary body 120 is controlled to detected counteracting force for certain.
Wobble drive portion 140 produces the driving force that makes a plurality of ultrasonic units 130 (being ultrasonic unit 130A and ultrasonic unit 130B) swing usefulness in embodiment.Specifically, wobble drive portion 140 is rotated centered by the rotating shaft 141 that extends along crisscross CD.In addition, wobble drive portion 140 has the arm guide part 142 that is led in the 1st end 151 of swing arm 150.Arm guide part 142 arranges along the circumference centered by rotating shaft 141, along circumference is led in the 1st end 151 of swing arm 150.
Some (being ultrasonic unit 130A in embodiment) in swing arm 150 and a plurality of ultrasonic units 130 is connected.Swing arm 150, the driving force that utilizes wobble drive portion 140 to produce make a plurality of ultrasonic units 130 along guide part 170 swings, and this guide part 170 extends along rotary body 120 outer peripheral faces 122.
Specifically, swing arm 150 has the 1st end 151 and the 2nd end 152.The 1st end 151 is connected with the arm guide part 142 of wobble drive portion 140, and is directed to along the arm guide part 142 of wobble drive portion 140.Some (being ultrasonic unit 130A in embodiment) in the 2nd end 152 and a plurality of ultrasonic units 130 is connected, and by the some supports rotationally in a plurality of ultrasonic units 130.
In embodiment, wobble drive portion 140 and swing arm 150 constitute the swing mechanism that a plurality of ultrasonic units 130 are swung along guide part 170, and this guide part 170 extends along the outer peripheral face 122 of rotary body 120.
Linking arm 160 is connected a plurality of ultrasonic units 130 (being ultrasonic unit 130A and ultrasonic unit 130B in embodiment).In embodiment, linking arm 160 has along the outstanding projection 161 of the direction (be crisscross CD) identical with rotary body 120 rotating shafts 121.
