Description

The present invention relates to an apparatus for manufacturing a face mask in a container and a method for manufacturing a face mask in a container, which are formed by accommodating a plurality of face masks in a container.

Conventionally, in a face mask containing a container, for example, as disclosed in Patent Document 1, in order to improve portability, a single material sheet impregnated with a beauty essence is wound in a spiral shape to form a wound body. In some cases, the wound body is housed in one tray in the shape of a bottomed container.

This face mask in a container is conventionally manufactured by the following method. The material sheet is punched out from the material web continuously supplied from the original roll, and while the obtained material sheet is conveyed by a conveyor, it is a bending line in the vertical direction parallel to the conveying direction and is located in the center in the left-right direction. The material sheet is folded in half by a line, and the beauty essence is impregnated into the material sheet by spraying the beauty essence on the surface of the folded material sheet during transportation from a nozzle, and the material sheet impregnated with the beauty essence is swirled by a molding device. It is wound into a wound body, which is discharged from the molding apparatus, stored in a tray, and sealed and packaged in a packaging bag.

This sealed and packaged face mask in a container is convenient when carrying it, but for example, when a large number of face masks are stocked in a dressing room or the like and used regularly on the spot. Is inconvenient in terms of storage and handling. In other words, this face mask in a container has a relatively large individual occupied space because the face mask itself is wound and stored in a tray and sealed in a packaging bag, and it has a capacity to stock a large number of them. A large storage space is required, which may make the dressing room small. In addition, each time it is used, it is necessary to tear the packaging bag in order to remove the face mask, and since the torn packaging bag and empty tray become garbage, it is also necessary to dispose of it. Become.

On the other hand, face masks in containers, which are made by stacking and accommodating a large number of face masks in a single container in a folded state, have a relatively small occupied space and are easy to handle. There is also increasing demand for this type of containerized face mask.

Japanese Unexamined Patent Publication No. 2017-52532

However, when the face mask is stored in a container in a folded state, in order to minimize the bottom area of the container, the face mask is folded with at least one vertical bending line, and then with at least one horizontal bending line. Need to fold. Then, after spraying the chemical solution onto the surface of the material sheet folded by the vertical bending line as in the conventional method, the material sheet that has received the sprayed chemical solution is folded in half by the horizontal bending line and stored in the container. In this case, the chemical solution must permeate from the front surface of the upper material sheet to the back surface of the material sheet at the folded portion, and further permeate from the front surface of the lower material sheet to the back surface of the material sheet.

At this time, if the chemical solution has a relatively high viscosity, the chemical solution does not easily penetrate into the material sheet, so that a sufficient amount of the chemical solution does not easily penetrate to the back surface of the material sheet under the folded portion, and the face. There is a problem that the mask becomes a defective product with uneven impregnation of the chemical solution and causes a decrease in yield.

When the material sheet is wound in a spiral shape, the front surface of the wound material sheet and the back surface of the material sheet wound on the upper layer face each other, but the material sheet is folded in half and laminated. In that case, the front surface and the front surface of the folded material sheet or the back surface and the back surface face each other, and there is an opportunity for the beauty essence adhering to the front surface of the material sheet to directly adhere to the back surface of the material sheet. It is considered that the main cause of the problem of uneven impregnation of the chemical solution is that it does not easily penetrate into the material sheet if the chemical solution has a high viscosity.

Therefore, in order to eliminate impregnation unevenness, it is conceivable to continuously spray the chemical solution on both the front and back surfaces of the running material web before punching from the material web to the material sheet. In that case, the material sheet may be sprayed continuously. Since the rest of the material web that has been punched out is discarded, a large amount of wasted chemicals will be generated, and if the chemicals adhere to the material web, subsequent punching and folding will be difficult. Become.

The present invention has been made in view of such conventional circumstances. A main object of the present invention is to use a face mask in a container in which a large number of face masks are stacked in a folded state and stored in a container, even if each face mask uses a relatively high-viscosity chemical solution. To provide an apparatus for manufacturing a face mask in a container and a method for manufacturing a face mask in a container, which can be manufactured so as not to cause uneven impregnation of the chemical solution, and can be efficiently manufactured with less waste of the chemical solution. be.

In this embodiment, the face mask manufacturing apparatus 100 in a container shown in FIG. 3 is used to manufacture the face mask 1 in a container.
(Face mask manufacturing device 100 in a container)

An embodiment of the face mask manufacturing apparatus containing a container according to the present invention will be described with reference to FIGS. 3 to 6. As shown in FIG. 3, the face mask manufacturing apparatus 100 includes a driven feeding roller 4 for pulling out the material web W from a raw roll (not shown) and a rotary for continuously punching out the material web W fed out from the feeding roller 4. The main components are the die cutter 5, the folding device 8 that bends and folds the material sheet S sent out from the rotary die cutter 5 along the folding line L1 shown in FIG. 2, and the folding device 9 that bends and folds the material sheet S sent out from the rotary die cutter 5 along the folding line L2 shown in FIG. Prepare as a department.

Further, as shown in FIG. 3, the face mask manufacturing apparatus 100 includes a first roller 16 that rotates while adsorbing the material sheet S1 folded by the folding apparatus 8 and the folding apparatus 9, and a first roller 16. A second that rotates while placing the chemical liquid injection nozzle 17 that injects the chemical liquid onto the rotating material sheet S1 and the material sheet S2 that has received the chemical liquid injection from the chemical liquid injection nozzle 17 so that the surface side faces the outer peripheral surface. The roller 18, the chemical liquid injection nozzle 19 for injecting the chemical liquid toward the back surface of the material sheet S2 placed on the outer peripheral surface of the second roller 18, and the material sheet S3 on which the chemical liquid is sprayed on the back surface are bent as shown in FIG. The main part is a folding roller 20 that is folded along the line L3 and folded in half, and a receiving unit 30 that drops and accommodates the face mask 3 in which the material sheet S3 is half-folded in the container 2 prepared below. ..
(Punched part)

As shown in FIG. 3, the material web W is drawn out from the raw roll (not shown) by the driven roller 4, and is continuously supplied to the rotary die cutter 5 including the die cutter 5a and the anvil roll 5b. The material sheet S is punched out one after another by the rotary die cutter 5.

The punched material sheet S has its vertical direction oriented in the transport direction of the material web W, is sent out from the rotary die cutter 5 at regular intervals, and is sequentially adsorbed by the adsorption roller 6 and then adsorbed. It is passed from the roller 6 to the suction conveyor 7.

The suction roller 6 is a driven roller having a large number of suction holes capable of negative pressure suction only in a region of a certain rotation angle on the outer peripheral surface thereof, and the suction conveyor 7 is capable of suctioning a large number of negative pressures on the belt. It has a suction hole. The remaining part of the web W from which the material sheet S is punched is divided into left and right, and each becomes a waste web T, which is transported to another place and wound up.
(First folding part)

As shown in FIG. 3, a folding device 8 and a folding device 9 are arranged on the downstream side of the suction conveyor 7, and the folding device 8 holds the material sheet S passed from the suction conveyor 7 at the center of the lower surface thereof. The material sheet S is bent and folded along the folding line L1 shown in FIG. 2 by moving along the guide surface of the known folding plate 11 while sucking and transporting the material sheet S by the suction conveyor 10. After that, the folding device 9 folds the material sheet S along the folding line L2 shown in FIG. 2 by the suction conveyor 12 and the folding plate 13 in the same manner as the folding device 8. The material sheet S0 is transferred from the suction conveyor 10 to the suction conveyor 12 by the suction conveyor 14. The code of the material sheet folded by the folding device 9 is S1. Further, the material sheet S1 is supplied to the upper part of the first roller 16 by the suction conveyor 15.
(First chemical injection part)

As shown in FIG. 4, the first roller 16 is a driven suction roller having a suction hole on the outer peripheral surface like the suction roller 6 described above, and rotates in the direction indicated by the arrow A1 from the rotation angle θ1. It has an adsorption function in the region up to θ2. A chemical liquid injection nozzle 17 is arranged above the region having the suction function of the first roller 16 with the injection port facing the outer peripheral surface of the first roller 16.

The back surface of the material sheet S1 supplied from the suction conveyor 15 is placed so as to face the outer peripheral surface of the rotating first roller 16, and in that state, the material sheet S1 is sucked and conveyed by the first roller 16 and is conveyed to the nozzle. While passing under the chemical solution 17, the chemical solution is ejected from the chemical solution injection nozzle 17.

In the case of this embodiment, as shown in FIGS. 5 and 6, the chemical liquid injection nozzles 17 are arranged at two locations on the left and right as the nozzles 17a and 17b so as to separately correspond to the right half and the left half of the material sheet S1. The chemicals are ejected from the chemical injection nozzles 17a and 17b arranged at the two left and right positions toward the material sheet S1. As shown in FIG. 6, the nozzle 17a is arranged so as to be inclined by approximately 45 ° counterclockwise with respect to the flow direction of the material sheet S1, and the nozzle 17b is substantially clockwise with respect to the flow direction of the material sheet S1. It is arranged at an angle of 45 °. As a result, the injection pitch of the chemical solution in the material sheet S1 can be made denser than in the case where the nozzle 17 is arranged perpendicular to the flow direction. Further, when one chemical liquid injection nozzle 17 is arranged in an inclined manner, the injection ports of the nozzles are usually arranged in a row, so that the chemical liquid is sprayed at the start of injection when the chemical liquid starts to be applied to the material sheet S1. Where most of the chemical solution does not hang on the material sheet S1 and the injection loss of the chemical solution is large, the injection loss of the chemical solution can be reduced by arranging the chemical solution injection nozzles 17 at two locations on the left and right. Here, it is designated as the reference numeral S2 of the material sheet in which the chemical solution is sprayed by the nozzle 17.

A second roller 18 that rotates in the opposite direction to the first roller 16 is provided in close proximity to the first roller 16 at the diagonally lower side of the first roller 16 on the region side where the material sheet S1 is adsorbed. be. The reason why the second roller 18 is placed diagonally downward so as to be close to the first roller 16 is that the vertical line in contact with the circumference of the first roller 16 always intersects the circumference of the second roller 18. This is so that the material sheet S1 released from the first roller 16 can be placed on the outer peripheral surface of the second roller 18. The second roller 18 has the same outer diameter as the first roller 16 and is rotationally driven so as to be synchronized with the same outer peripheral speed as the first roller 16.

When the material sheet S2 on the first roller 16 passes through the suction region of the first roller 16, it is released from the first roller 16, and the tip of the material sheet S2 is guided to the second roller 18 by gravity. It rests on the outer peripheral surface of the second roll 18.

Since the second roller 18 rotates in the reverse direction with respect to the first roller, the outer peripheral surface of the second roller 18 on which the material sheet S2 is placed moves downward at substantially the same speed as the opened material sheet S2. The front surface side of the material sheet S2 mounted on the second roller 18 is the side facing the outer peripheral surface of the second roller 18. Since the chemical solution is jetted and adhered to the surface side of the material sheet S2, the material sheet S2 adheres to the outer peripheral surface of the second roller due to the viscosity of the chemical solution.
(Second chemical injection part)

Below the first roller 16, a chemical liquid injection nozzle 19 is arranged with the injection port facing the outer peripheral surface of the second roller 18. The material sheet S2 placed on the outer peripheral surface of the second roller 18 is conveyed downward by the rotation of the second roller with its back surface facing outward, and at that time, the chemical liquid is conveyed to the back surface of the material sheet S2 from the chemical liquid injection nozzle 19. Is jetted. As a result, the central portion of the material sheet S2 in the width direction is impregnated with the chemical solution by the injection from the back surface side by the second chemical solution injection portion, so that the chemical solution can be supplied from the back surface side of the material sheet S2 to the inside thereof as well. .. In other words, even when a chemical solution having a relatively high viscosity is used, the chemical solution can be sufficiently permeated to the inside of the portion of the material sheet S2 that is folded by the first folded portion. Here, the reference numeral of the material sheet on which the chemical solution is sprayed on the back surface is S3.
(Second folding part)

In order to fold the material sheet S3 along the folding line L3 shown in FIG. 2 and fold it in half, a folding roller 20 is placed diagonally below the side of the second roller 18 on which the material sheet S2 passes. A folding table 21 is provided on the outer peripheral surface of the second roller 18. The folding table 21 is composed of an edge portion of a plate member mounted on the second roller 18, extends parallel to the rotation center axis of the second roller 18, and projects from the outer peripheral surface of the second roller 18. In the case of the apparatus shown in FIG. 3, the folding table 21 is arranged at a position where the circumference of the second roller 18 is divided into four equal parts.

The folding roller 20 has the same outer diameter as the second roller, and is rotationally driven to synchronize with the second roller 18 at the same outer peripheral speed. The folding roller 20 is provided with a grip portion 22 so as to face the folding table 21, and the grip portion 22 extends in the width direction on the outer peripheral surface of the folding roller 20 provided on the outer peripheral surface of the folding roller 20. It has a groove 23 and a sandwich plate 24 pivotally supported in the width direction of the folding roller 20, and is provided at four locations on the peripheral surface of the folding roller 20 in the device shown in FIG.

As shown in FIG. 4, the groove 23 includes an inner wall 25, accommodates the sandwich plate 24, and has a depth and width at which the sandwich plate 24 can swing. The sandwich plate 24 is a plate extending in the width direction of the folding roller 20, and is formed to have a height that does not protrude from the peripheral surface of the folding roller 20 and a thickness that allows swinging in the groove 23. Holds the material sheet S3 with.

The second roller 18 is phase-adjusted with respect to the first roller 16 so that the vertical center portion of the material sheet S2 supplied from the first feed roller 16 is directly above the folding table 21. As shown in FIG. 4, the folding roller 20 is phase-adjusted with respect to the second roller 18 so that the folding table 21 enters the groove 23.

As shown in FIG. 4, when the folding table 21 enters the groove 23, the sandwich plate 24 turns from the standby position, sandwiches the material sheet S3 between the folding table 21 and the inner wall 25, and then sandwiches the material sheet S3 between the folding table 21 and the inner wall 25. As the second roller 18 and the folding roller 20 rotate, the folding table 21 having a relatively small surface friction coefficient is extracted from the groove 23.

Then, the material sheet S3 whose central portion is sandwiched between the sandwich plate 24 and the inner wall 25 remains on the folding roller 20, and is conveyed to the open position together with the folding roller 20. At this time, the front half of the material sheet S3 that preceded on the second roller 18 is also pulled back to the folding roller 20 side along the guide plate 26 by the rotation of the folding roller 20 and folded over the rear half of the material sheet S3. The face mask 3 is folded in half.

In order to scrape the face mask 3 that has reached the open position under the folding roller 20 from the folding roller 20, a groove 27 is formed in the circumferential direction on the outer peripheral surface of the folding roll 20, and the folding roller 20 is formed. A plate-shaped swing claw 28 is attached to the rotation shaft 29 provided in parallel with the rotation center axis of the above.

When the face mask 3 reaches the open position, the sandwich plate 24 retracts from the inner wall 25 to open the face mask 3, and then the rotation shaft 29 rotates and the rocking claw 28 waiting in the groove 27 The face mask 3 protrudes from the groove 27 and is scraped off from the lower outer peripheral surface of the folding roller 20 and falls to the receiving portion 30 provided on the lower side of the folding roller.
(Accommodation)

The receiving unit 30 includes a pair of opening / closing plates 31 that can be opened / closed in the horizontal direction, and receives the face masks 3 falling one after another from the folding roller 20 into the pair of opening / closing plates 31 in the closed state, and receives the faces. When the number of masks 3 reaches a predetermined number, the pair of opening / closing plates 31 are opened, and the face masks 3 are dropped and accommodated in the container 2 prepared below. When the number of face masks 3 housed in the container 2 reaches the required number, the face mask 1 in the container is completed. The face mask 1 in a container is sent to a packaging process for packaging.
(Third chemical injection part)

In the pre-stage of this packaging process, in order to obtain a face mask in a container containing a large amount of chemical solution, the face mask 1 in a container is further conveyed to a third chemical solution injection step after the above-mentioned storage step is completed, and the inside of the container 2 is provided. It is advisable to inject the required amount of chemical solution into the product. At that time, by pressing the bundle of face masks 3 stacked in the container 2 from above, a large amount of chemical solution can be further impregnated into the material sheet S.
(Flow of manufacturing method of face mask in container)

FIG. 7 is a flowchart showing an example of the flow of the face mask manufacturing method containing a container. As shown in FIG. 7, first, in the punching process, the driven roller 4 pulls out the material web W from the raw fabric roll (not shown), and the rotary die cutter 5 punches out the material sheet S one after another (step). ST101). Next, in the first folding step, the folding device 8 bends and folds the material sheet S along the folding line L1 shown in FIG. 2, and then the folding device 9 bends the material sheet S as shown in FIG. 2 in the same manner as the folding device 8. Bend and fold along the line L2 (step ST102).

Next, in the first chemical injection step, the first roller 16 rotates while adsorbing the folded material sheet S1, and the chemical injection nozzle 17 rotates on the material sheet S1 rotated by the first roller 16. The chemical solution is sprayed (step ST103). Then, in the second chemical injection step, the second roller 18 rotates while being placed so that the surface side of the material sheet S2 that has received the chemical injection from the chemical injection nozzle 17 faces the outer peripheral surface. The chemical solution injection nozzle 19 injects the chemical solution toward the back surface of the material sheet S2 placed on the outer peripheral surface of the second roller 18 (step ST104). Subsequently, in the second folding step, the folding roller 20 bends the material sheet S3 on which the chemical solution is sprayed on the back surface along the folding line L3 shown in FIG. 2 and folds it in half (step ST105). Next, in the accommodating step, the receiving unit 30 drops the face mask 3 formed by folding the material sheet S3 in half into the container 2 prepared below and accommodates it (step ST106).

After accommodating the face mask 3 in the container 2, the face mask 1 in the container may be further conveyed to the third chemical liquid injection step, and a required amount of the chemical liquid may be injected into the container 2 (step ST107). Finally, in the packaging process, the face mask 1 in a container is packaged (step ST108).

As described above, according to the present invention, a face mask in a container in which a large number of face masks are stacked in a folded state and stored in a container is used, and each face mask uses a chemical solution having a relatively high viscosity. Even if it is, it can be manufactured so that the impregnation unevenness of the chemical solution does not occur, and moreover, the waste of the chemical solution can be suppressed and the production can be performed efficiently.

The device for carrying out the method for manufacturing the face mask in a container of the present invention is not limited to the device shown in FIG. For example, the material sheet folded in the first folding step may be supplied from the first roller to the second roller by using another transport means such as a suction conveyor. Further, the device for carrying out the second folding step may not be provided with the folding roller shown in FIG. 3 as long as the material sheet can be automatically folded.

The method for manufacturing a face mask in a container of the present invention can be applied to an application for manufacturing a face mask in a container in which a large number of face masks are stacked in a folded state and housed in a container.
