It is preferable to include a rubber string winding pipe 76 wound around P2.

(Operation) The operation of the method and apparatus for manufacturing the disposable mask having the above configuration will be described. In step (I), sheet roll PO
A breathable long belt-shaped raw sheet P is wound around the sheet roll PO, and the raw sheet P is continuously fed out from the sheet roll PO by the feeding means 1, and in the step (n), the raw sheet P is rolled in the width direction by the folding means 2. It is continuously gathered and folded. As the raw sheet P, air-permeable paper, non-woven fabric, or even a non-woven fabric laminated and coated with a large number of pores is used.

In step [III), the raw fabric sheets stacked at predetermined intervals in the longitudinal direction of the raw fabric sheets P continuously gathered and folded as described above are bonded together by thermocompression by the heat fusion/cutting means 3, In addition, the raw sheet P is cut into cut sheet pieces P' at regular intervals in the longitudinal direction so that the thermocompression bonded portions P1 in the width direction are located at both ends. The cut sheet pieces P' are sequentially transported and placed one by one on each table 5 of the conveyor 50.

The cut sheet pieces P' placed on the table 5 of the conveyor 50 are successively conveyed by the intermittent drive of the conveyor 50, and in step (IV), the end pieces P2 are raised by the end piece upright means 6. ．． The standing up process of P2 is performed. The narrow grooves 51, 51 and the wide groove 52 on the top surface of the table 5...
is formed and the end piece upright means 6 is configured as shown in FIG. The center portion of the upper sheet piece P' becomes concave and slack.

Next, the restraining member 62 rises, and the vertically movable plate 6
1.61 descends and its lower end portions fit into the narrow grooves 51, 51, the central portion of the sheet piece P' is pulled in both directions, and both end pieces P2. P2 stands up. At this time, since the central part of the sheet piece P' has been loosened in advance, the above-mentioned tensile force is absorbed by this slack part, so that the surface perpendicular movable plate 6
Even if there is a slight deviation in the lowering timing of 1.61, the end pieces P2, P2 will not be offset and will all stand up with the same width.

As mentioned above, both end pieces P2. Sheet piece P' with P2 standing up
is sent to the next rubber string winding step (V) together with the table 5 by the intermittent drive of the conveyor 50. Main process〔■
], the above-mentioned upright end pieces P2. The rubber string S is wound in a ring around P2, and the winding is performed as follows in the rubber string feeding/winding means 7 and table 5 preferably employed in the present invention. That is, in FIGS. 6 and 7, a rubber string S is unwound from a rubber string raw roll SO supported by a roll support section 71, and the rubber string S is connected to a rubber string guide tube 73 and a second rubber string. It passes through a string guide tube 75 and hangs down from the tip of a rubber string winding pipe 76. When the rubber string S in the second rubber string guide tube 75 is stopped by the rubber string stopper 75a and the feeding rod 74 is swung as if hitting, the rubber string S is caught by the feeding rod 74, and the rubber string S is caught by the feeding rod 74. As for the hook, the rubber string S is let out from the roll SO by a length corresponding to the slack. Then, compressed air is supplied from the supply lower 3a to cause the excess amount to be fed back, so that the rubber string S is slightly stretched around the feeding rod 74. The surplus string S caused by this reverse feeding is received by the cover plates 72, 72 and is prevented from hanging. At this time, the length of the rubber string S that is fed out by the hook of the feeding rod 74 corresponds to the length of one winding.

Thereafter, when the stopper 75a is released and the winding pipe 76 is rotated, the rubber string S hanging from the tip of the pipe 76 is unwound while the rubber paper presser pin 5
3.53 and the guide pin 54... At this time, the holding pins 53 and 53 are pushed upward by a push-up member 77 as shown in an embodiment described later. Immediately before the winding pipe 76 rotates approximately one turn and the table 5 begins to move, the stopper 75a operates to stop the rubber string S in the guide tube 75. Thereafter, the restraining pins 53, 53 move downward to restrain and fix the cross-shaped portion Sl of the rubber string S. Then, the next table 5 is moved to a position directly below the winding pipe 76 by the intermittent driving of the conveyor 50, and the same operation as described above is repeated with the rubber string S being under tension between each table 5, 5. The operation of the feed rod 74, the compressed air supply timing, the operation timing of the stopper 75a, the rotation timing of the winding pipe 76, etc. are performed based on a predetermined timing chart.

Sheet piece P' that has undergone the rubber string winding process (V) as described above
In the next step [VI], adhesive is supplied to the cross-shaped portion SL of the wound rubber string S by the forming means 8, and the raised end pieces P2 and P2 are turned inward. Folded back to form the above-mentioned shape portion Sl.

Sl is the end piece P2. It is sealed by P2. after that,
The continuous rubber string S is cut for each sheet piece P'...
Ear loops S2°S2 are formed on both sides of each sheet piece P'. When cutting the rubber string S, the tension is applied as described above, so that at the same time the cut end is cut, the elasticity of the cut end restores the elasticity of both end pieces P2. Since it is retracted into the folded portion of P2, it is not visible from the outside, which has the added advantage of improving the appearance.

After that, the above ear hooks were transferred to S2. S2 is pin 53°53.5
4..., and the product G... is transferred to the conveyor 50.
Then, the process moves to the arranging means 9, where they are arranged in an orderly manner and packed into predetermined quantities.

(Example) Next, an example will be described.

In the figure, the feeding means l for the raw sheet P consists of two biased raw sheet roll support parts 11.11 and a plurality of tension rolls 12...
The breathable long belt-shaped raw sheets P, P fed out are stacked one on top of the other and reach the folding means 2 via the tension rolls 12 . The folding means 2 arranges rod-shaped or plate-shaped finger members 21 in the feed line of the raw sheet P, and by appropriately combining them, the continuously fed raw sheet P is shaped into a desired pattern. It is intended to be folded continuously into the belt, and a conventionally known means for folding the belt-shaped material is adopted.

Reference numeral 22 denotes a pull-out roll, which forcibly pulls out the raw sheet P and presses it from above and below to form a regular folded shape. It is desirable that the rotational speed of this pull-out roll 22 can be adjusted by a transmission (not shown).

The heating fusing/cutting means 3 includes a heat roll 31°31,
It consists of a take-out roll 32.32 with a transmission and a rotary cutter 33.33. One circumference of the heat roll 31.31 has at least two parallel protrusions 31a each containing a built-in heater.

31a is formed along the thrust direction, and the other heat roll 31 is a heater receiving roll whose surface is plated or treated with silicon or Teflon. The raw sheet P that has passed through the heat rolls 31° 31 has at least two striped thermocompression bonded portions P at regular intervals.
L and PL are formed, and the upper and lower parts are thermally fused to each other at this location. Heat roll 31. Take-out roll 3 following 31
2°32 is arranged, and the detecting roll 32.32 is
It functions to take over the raw sheet P that has been heat-fused and supply it to the rotary cutters 33 and 33. A cutter 33a is fixedly installed on one side of the rotary cutter 33.33, and as the cutter 33a rotates, the raw sheet P is continuously supplied.
Cut into certain dimensions.

The rotation period of the cutter 33a is
The cutter 33a is set to have an action site between the adjacent striped thermocompression bonding parts PL, in accordance with the formation interval PL. Therefore, at least one striped thermocompression bonded portion P1 exists at both ends in the longitudinal direction of the cut sheet piece P'.

The cut sheet pieces P'' sequentially delivered by the heat fusing/cutting means 3 are transported by a conveyor 50 which is intermittently driven.
The sheets are placed one by one on the table 5 using the delivery bag W4. That is, as shown in FIG. 3, the delivery device 4 includes a frame 40 that is vertically swingable about a pivot 40d, and a frame 40 that is stretched in the front-rear direction of the frame 40.
an endless perforated timing belt 41.41; a pair of front and rear suction chambers 42.43 disposed so that the openings are in contact with the upper surfaces of the outgoing sides of the timing belts 41, 41;
It consists of a sheet piece lifting suction lift 44 installed at a receiving section for cut sheet pieces, and a sheet piece pushing up lift 45 installed directly below the suction lift 44. The frame 40 is horizontally suspended between the sheet piece delivery stand 30 and the starting end of the conveyor 50. Further, a solenoid valve 43a is installed in the suction hose connected to the suction chamber 43 at the front of the traveling side, and the suction in the suction chamber 43 is turned on and off as appropriate. The above-mentioned push-up lift 45 approaches the sheet piece P' that has been heat-fused and cut and delivered as described above, and the sheet piece P' is sucked to the suction pad 45a fixed at the tip thereof. A suction lift 44 descends from above and attracts the upper surface of the sheet piece P'. Then, the suction lift 44 and the push-up lift 45
simultaneously rises, and the sheet piece P' reaches the timing belt 41.
It touches the bottom surface of ゜41. The timing belt 41°41
The sheet piece P' is attracted to the lower surface of the timing belt 41, 41 by negative pressure in the suction chamber 42 through the holes 41a, which are spaced apart along the longitudinal direction. At this time, the support of the suction lift 44 and the push-up lift 45 is released, and the sheet piece P' is conveyed while being attracted to the lower surface of the belt 41.41 as the timing belt 41.41 is driven intermittently. When the sheet piece P' reaches below the second suction chamber 43, the frame 40 swings downward and the sheet piece P' is pressed onto the table 5 of the conveyor 50. At this time, the solenoid valve 43a of the suction chamber 43 is turned off, and the sheet piece P' separates from the timing belt 41, 41. Thereafter, when the frame 40 is swung upward, the sheet piece P' remains on the table 5. The frame 40 is vertically oscillated by a cam mechanism 40a driven by a motor, and a spring 40c is elastically loaded between the frame 40 and a crank 40b associated with the cam mechanism 40a. It is designed to prevent the pressing of the

As mentioned above, the sheet piece P delivered onto the table 5...
' is intermittently transferred by the drive of the conveyor 50, and processed in the next steps (IV) to [VI].

As described above, the end piece upright means 6 is composed of a pair of left and right vertically movable plates 61, 61, and a soft elastic sheet restraining member 62 disposed at the center thereof. The sheet holding member 62 is made of a soft elastic material such as sponge, and has a cylinder 6 that expands and contracts vertically.
It is attached to the lower end of 2a. Directly below the end piece upright means 6 is a suction pipe 63 M! 1t, and when the table 5 is transferred and installed at a predetermined position, the suction pipe 63 rises, and the hole 52a opened approximately in the center of the wide groove 52 of the table 5 is opened.
Start suctioning more. At about the same time, the sheet holding member 6
2 is lowered, and due to the above-mentioned suction action, the center portion of the cut sheet piece P' is pushed into the wide groove 52 and loosened.

After that, the sheet pressing member 62 pushes the suction tube 6
3, the vertically movable plate 61.61 is lowered, and the vertically movable plate 61.6 is inserted into the slit-like narrow grooves 51, 51.
When the lower end of 1 is inserted, both end pieces P2 of sheet piece P'
．． P2 stands vertically. At this time, the center part of the sheet piece P' is subjected to a pulling action in the left-right direction,
Since this tensile force is absorbed by the slack portion, both end pieces P2. No interaction is added to P2, and both end pieces P
2. P2 will definitely stand up with the same width.

The sheet piece P' that has been subjected to the above-mentioned raising process is conveyed to a location where the rubber string feeding/winding means 7 is installed by intermittent movement of the table 5. Since the structure and operation of the rubber string feeding/winding means 7 are as described above, a supplementary explanation thereof will be given here. Posts 70 (70) are erected on both sides of the conveyor 50, and roll support portions 71 (71) are formed laterally on the posts 70 (70). And each roll support part 71
Plastic sagging cover plates 72 are placed on the top and bottom of the
゜72 is arranged. The rubber string S drawn out from the rubber string raw roll SO supported by the roll support part 71 is
It is inserted through the rear tube and second copper rubber string guide tubes 73 and 75 which are engaged with double rings 71a and 71b. The feeding rod 74 installed between the first and second rubber string guide tubes 73 and 75 is curved and can swing up and down about a pivot point 74a in the middle as a fulcrum. The proximal end of the feeding rod 74 is tied to the tip of the telescopic rod of the cylinder 74b, and the feeding rod 74 is connected to the cylinder 74b. It swings up and down by the telescopic drive of 4b. The rubber string S is fed out from the raw roll SO by a stopper 65a in the second rubber string guide tube 75.
This is done by activating and fixing the rubber string S, and then swinging the feeding rod 74 downward to hook and loosen the rubber string S between the rubber string guide tubes 73 and 75. At this time, the excess slack is reversed by supplying compressed air from the supply lower 3a, so that the rubber string S is kept taut on the feeding rod 74. The second rubber cord guide tube 75 is bent into an elbow shape,
It is cut out in the middle, and the actuating part of the stopper 75a is inserted into this cut-out part. The stopper 75a uses an air cylinder or the like as a driving source, and when turned on, presses the rubber string S in the guide tube 75 against the tube wall, making it impossible to draw it out or draw it in.

Said guide tube 75.75 is connected to a winding pipe 76.76 mounted rotatably about a vertical axis. The winding pipe 76 includes a vertical straight guide pipe 76a and a bent finger pipe 76b connected to the lower end of the guide pipe 76a. And the guide pipe 76a,
The upper end of 76a is rotated about a vertical axis by power transmission via horizontal drive shafts 76c, 76c' and bevel gears 76d, 76d. The horizontal drive shafts 76c, 76c' incorporate a clutch brake or the like and drive it based on a desired setting mode. The rubber strings S, S are the guide pipes 76a, 76a.
and the finger pipes 76b, 76b, and are suspended from the tips of the finger pipes 76b, 76b. Due to the rotation of the finger pipes 76b, 76b, the inserted rubber strings S, S stand up on both end pieces P2. It will be wound around P2, but at this time the lock by the stopper 75a is released and the feed rod 74
As explained above, the hook is retreating from the position. Reference numeral 78 is a sheet presser installed between the winding pipes 76 and 76, which descends when the rubber string S is wound and presses both ends of the paper piece P' on the table 5 in the traveling direction from above. This is intended to prevent the sheet piece P' from shifting during winding. The sheet piece restrainer 78 includes a vertical driving means 78a such as an air cylinder, and a pair of front and rear restraining members 78b, 78b made of urethane or the like fixed in a gate shape at the lower end of the driving means 78a (however, only one is shown in the drawing). ), which makes it desirable to be adopted.

In the vicinity of both ends of the narrow groove 51 of the table 5, rubber restraining pins 53.53 that can freely swing up and down are installed, but the pins 53.53 are normally elasticized downward by compression springs 53a, 53a. Forced. And table 5
A push-up member 77 is installed below the push-up member 77, and the pins 53 and 53 are pushed up as the push-up member 77 rises against the elasticity of the springs 53a, 53a. When the rubber strings S, S are wound in this state, they are sandwiched between the heads of the pins 53, 53 and the table 5, and when the push-up member 77 is lowered, the springs are released. The elastic strings S, S are pressed and fixed between them and the table 5 by the elasticity of the elastic members 53a, 53a. The rubber strings S, S are wound around the pins 53, 53 and the guide pins 54 on the auxiliary plates 55, 55 connected to both sides of the table 5. A plurality of guide pins 54 with different planting patterns are prepared and are detachable from the table 5, and these are replaced as appropriate depending on the size of the ear hook.

With the intermittent movement of the table 5, the piece of paper P' on which the rubber string has been wound is fixed with an adhesive, the adhesively fixed portion is sealed, and the rubber string is cut. That is, the ear loop forming means 8 includes a hot melt adhesive pouring device 81, and both end pieces P2. P2 folding device [82 and both folded end pieces P2. A holding device that holds down P2 from above! 83 and.

It consists of a rubber cord cutting device 84. Adhesive pouring [8

The folding device 182 is reciprocated by a driving means such as a cylinder from both sides of the paper piece P', and folds the two upright end pieces P2, P2 toward the center of the paper piece P'. The restraining device 83 is composed of a pair of left and right lifting members 83a, 83a, and holding members 83b, 83b, which are fixed to the lower ends and have a built-in heater. P2 from above to spread and harden the adhesive, and at the same time apply the adhesive to both end pieces P2. It functions to fuse P2 and seal the adhesively fixed portion. With this, the ear hooks can be transferred to S2. S2 are formed on both sides of the paper piece P''.Furthermore, the cutting devices 84, 84 cut the continuous rubber string S for each paper piece P'... on each table 5 using an air chuck type driving means. It functions as it should.

(Effects of the Invention) As described above, according to the present invention, a disposable mask can be efficiently manufactured using a consistent system.

In the process of winding the rubber cord to form the ear loop, both end pieces of the sheet piece are made to stand up in advance, so the winding pattern is stable and there is no variation in dimensions. No manual product modifications are required. In particular, when the rubber cord feeding/winding means is configured as claimed in claim 5, by appropriately setting the operation timing of each component, ear hooks of a certain size can be reliably formed into a loop and cut. At the same time, the cut end portions can be automatically drawn into the folded portions of both end pieces, thereby eliminating the need to cut off the end portions of the rubber cord and dramatically increasing the efficiency of the work. Therefore, production at an extremely low cost is guaranteed, and the disposable mask thus obtained literally exhibits full practical value as a disposable mask, and its useful value is extremely large.
