Description

[0001] MASK PACK AUTOMATIC BREAK APPARATUS [0002]

The present invention is applied to an apparatus for manufacturing a mask pack by folding a mask sheet used for facial skin care into a pouch into which a skin cosmetic agent such as a folding essence is inflated and sealed after folding the mask sheet to 1/3 width, To simplify the structure of the mask sheet feeding portion, to simplify the structure of the mask sheet folding portion, to pursue quick filling of the mask sheet, to improve the folding quality of the mask sheet, and to reduce the manufacturing cost.

The facial beauty massaging mask pack is formed by perforating the eye holes and the mouth holes in a mask sheet made of a nonwoven fabric cut in a shape and size suitable for covering the face, then folding and sealing in a pouch filled with a facial skin cosmetic agent such as essence.

The actual buyer who bought the mask pack opens the pouch, takes out the sheet of the mask, attaches it to the face, and massage the facial skin with the method of removing it after the effective use time.

When the mask pack was opened for the first time in the market, the process of folding the mask sheet to 1/3 width and folding it to 1/2 length and putting it in the pouch charged with skin beauty treatment was a manual-dependent type, and the manual inefficiency and unsanitary problem It has been attempted to automate a series of mask pack manufacturing operations such as injection, folding, pouch entry, and pouch sealing of the mask sheet.

Japanese Patent Application No. 10-1297461 discloses an image forming apparatus in which an extraction conveying means for separating a mask sheet laminated on a far-end lift sheet by a sheet by sheet and transferring the mask sheet to a work plate and returning the mask sheet is conveyed to the beginning of a folding means A first push bar-air nozzle for spraying compressed air from the side where the two-third portion of the mask sheet transferred to the first folding position of the folding means is pressed and folded upward, and a second push- A folding means consisting of a second pushbar-air nozzle that presses the picked portion of the mask sheet folded and folded by the first pushbar-air nozzle and folds the compressed portion of the mask sheet portion that has not been folded, A guide which guides the folded mask sheet to be conveyed to the position where the pouch guiding means is located, And a pouch feeding means for bringing the pouch into the waiting pouch in the lower portion thereof.

This prior art is an indispensable requirement that the mask sheet is taken out and conveyed, the first and second pressing means, and the guide for guiding the folded mask sheet inward, which complicate the construction of the mask pack automatic packaging apparatus It has been pointed out that the assembly difficulty is high and the production cost burden is also increased.

Further, there is a possibility that when the mask sheet exits from the first pressing bar and the second pressing bar, which are the strips having a large contact area after the first and second folding, the friction between the mask sheet and the mask sheet is large and the folded state is disturbed.

Japanese Patent No. 10-1571624 discloses a method for producing a mask sheet by supplying a rolled nonwoven fabric raw material to a blanking portion at a predetermined pitch to prepare a mask sheet through a line outline blanking, a posterior eye hole, a perforation hole and a connecting piece cutting process, And the remaining portion is folded over the folded mask sheet portion in advance and transferred to the pouch inlet portion to be packed.

Since this prior art is a mask sheet non-stacked type mask pack folding device, the seat lift and the mask sheet removal transfer device are meaningless. However, in the process of being conveyed to the pouch inlet after the second folding, the sheet lifting preventing means for pushing and guiding the folded mask sheet so as not to lift the folded mask sheet is too long, so that there is a large friction with the sheet lifting preventing means, There is a concern about quality, and the automatic design of the mask pack automatic packaging system is inevitable, and the production cost is also burdensome.

Further, since the pressing means for guiding the mask sheet to be folded to the 1/3 size is a belt plate having a large contact area with the mask sheet, the folded mask sheet is disadvantageously in friction with the mask sheet during the escape from the pressing means It is also a problem that can not be ruled out.

The present invention relates to an apparatus for producing a mask pack by folding a mask sheet made of a nonwoven fabric into a width of 1/3 and then inserting the mask sheet into a pouch filled with a facial skin cosmetic agent such as a folding essence, By simplifying the structure of the folding means, it is possible to improve the fabrication of the mask pack automatic packaging apparatus and reduce the manufacturing cost, increase the efficiency of folding by simplifying the folding process, and, in the course of escaping the mask sheet folding means, It is an object of the present invention to provide a mask pack automatic folding apparatus capable of obtaining a high quality mask pack by stabilizing the folded state.

A belt conveyor for conveying the mask sheet while intermittently orbiting the orbit in accordance with the feeding and folding of the mask sheet and the feeding cycle to the feeding station, A mask sheet feeding means for separating the uppermost mask sheet out of the mask sheets stacked on the sheet lift and returning to the feeding station of the belt conveyor and returning the mask sheet; A first air nozzle for folding one side (1/3 portion) of the sheet portion not pressed by the mask sheet on which the center 1/3 portion is pressed by the sheet pressing means, The other 1/3 portion of the unpressed mask sheet is folded forward And a second air nozzle which is folded so as to overlap on the mask sheet portion, wherein the mask sheet inputting means comprises a separating bar for an in-situ rotary mask sheet for taking up and separating the uppermost mask sheet and separating rod driving means, The folding means is provided with a pair of round bar guides having less friction with the mask sheet, and the first and second air nozzles are provided so as to face each other on the outside of the guide bars on both sides so that the first folding by the first air nozzle and the second folding by the second air nozzle And the second folding by the mask pack automatic folding device is performed in one place.

When the separating bar comes into contact with the upper surface of the uppermost mask sheet of the mask sheet lift, the mask sheet is hooked onto the mask sheet. After the mask sheet is put on the hook, the sheet- The winding then ascends and moves to the input station and turns it on the belt conveyor.

The guide bar of the mask sheet folding means is a rod which makes a linear contact with the mask sheet unlike the conventional belt strip pressing bar which is in surface contact with the mask sheet. When the guide bar is removed after the folding, the frictional resistance is small, And is smoothly conveyed toward the inlet.

A plurality of mask sheets are stacked and the uppermost mask sheet is separated from the mask sheet lift during storage. When the uppermost mask sheet is taken out and put into the belt conveyor, the leading end portion of the mask sheet is drawn by the hooks of the sheet separating bar, The mask sheet feeding means of the present invention is simple in construction compared to the mask sheet feeding means of Patent No. 10-1297461 comprising a cylinder for elevating and lowering the upper and lower plates, And it has a large effect of reducing manufacturing cost, facilitates separation of mask sheet, and is also easy to input into a belt conveyor.

In addition, the guide bar of the mask sheet folding means made of a pair of left and right is smaller in contact resistance with the mask sheet than the belt-type push bars of the Japanese Patent No. 10-1297461 and No. 10-1571624, so that the folded mask sheet is easy to escape from the folding means , And the folded state is also stable, so that the folding quality of the mask sheet is improved.

1, a mask pack automatic folding apparatus according to the present invention comprises a frame 10, a belt conveyor 20, a mask sheet feeding means 30, and a mask sheet folding means 40.

A normal mask sheet lift 50 for storing the contour of the face and the ordinary mask sheet with the eye holes and the entrance holes formed thereon stacked and stored in the belt conveyor 20 is disposed at the front end side of the frame 10, The rail 11 to be carried by the mask sheet feeding means 30 which reciprocates in the feeding station of the belt conveyor 20 in the lift 50 is laid parallel to the folding direction of the mask sheet.

It is known that the mask sheet lift 50 is automatically lifted by the amount corresponding to its weight each time the uppermost mask sheet is inserted into the sheet from the stacked mask sheet, thereby waiting for insertion of the subsequent mask sheet.

The rear end of the frame 10 is a mask sheet pull-in means 60 for folding the folded mask sheet in half length into a pouch, which is also known.

2, the belt conveyor 20 is a conveying means for conveying the mask sheet while intermittently orbiting the orbit along the direction of the folding station S2 and the pulling-in station S3 in the loading station S1, (Not shown).

The distance between the folding station S2 and the folding station S2 in the loading station S1 is the same as the distance between the folding station S2 and the loading station S3, Is equal to the transfer cycle of the inter-station mask sheet. The process then proceeds smoothly. This is a well-known technique in the same field. Reference numeral (C) denotes the locus of the mask sheet feeding means (30).

3, the mask sheet inserting means 30 separates the mask sheet stacked on the mask sheet lift 50 into a sheet, moves the sheet to an input station, replaces it, and repeats the cycle of returning, A bogie 31 moving on the rail 11 mounted on the frame 10 in the process direction and a lifting plate cylinder 32 attached to the bogie 31 to lower and raise the platform, A pedestal 33 attached to the lower end of the piston, a separator bar 34 for a mask sheet rotatably mounted on the platform 33, and a separator rod driving means 35.

The carriage 31, the lifting plate cylinder 32, and the platform 33 are well known in the mask pack automatic folding apparatus. Note here that the separation rods 34 are. The separation rods 34 are placed on the platform 33 in a direction orthogonal to the direction of conveyance of the mask sheet and descend to the top of the topmost mask sheet among the mask sheets stacked on the mask sheet lift 50, After the uppermost mask sheet is rotated by spinning, the uppermost mask sheet is separated while rising by the lifting plate cylinder 32, and then the mask sheet is transferred to the charging station

The mask sheet is lowered by the lifting plate cylinder 32 so that the mask sheet is lowered by the lifting plate cylinder 32 and then moved toward the mask sheet lift 50 which is the starting point together with the carriage 31 Return.

A hook 36 is attached to the main surface of the separating rod 34. The hook 36 is wound around the rotating sheet separating rod 34 so that the mask sheet is attached to the rotating shaft 32 so that the mask sheet is lightly stuck and is similar to or similar to the male portion of the Velcro if the mask sheet made of nonwoven fabric is an arm (female) And is useful for releasing the mask sheet at the charging station of the belt conveyor 20. [ The hook 36 may be attached to the entire surface of the sheet separating rod 34, or the hook 36 may be attached at a predetermined distance as shown in Fig.

3, the reciprocating means 37 for bogie moving the mask sheet by the separating bar 34 of the mask sheet lift 50 and moving it up to the feeding station of the belt conveyor for returning and returning the bogie 31, 10 between the input station and the transverse beams 12 attached on the fold line of the folding station.

It is usually a cylinder. This reciprocating means is also known from the same field.

When the separating bar 34 moves downward when the mask sheet of the mask sheet lift 50 is wound up, the separating bar driving means 35 rotates the separating bar 34 forward, And the one side shaft 38 of the separating rod 34 provided in the lateral direction so as to rotate in place in the left and right bearings of the pedestal 33 and the cylinder is connected to the link (39). ≪ / RTI >

5, the mask sheet folding means 40 injects the compressed air sequentially from both sides in a state in which the mask sheet fed from the input station to the folding station is pressed and stabilized, thereby folding the mask sheet in 1/3 size Elevating cylinders 41 and 42 for guide bars installed at a predetermined distance on the transverse beams 13 of the frame 10 and guide bars 43 and 42 attached to the lower ends of the pistons of the elevating cylinders 41 and 42, 44 and air nozzles 45, 46 provided on the frame 10 outside the guide bars 42,

The elevating cylinders 41 and 42 are identical to the existing elevating and lowering means for the mask sheet pressing bar, except that they are made up of two sets. Air nozzles 45 and 46 are also known. Another point to note is the guide bars (43, 44) corresponding to the existing push bars. The guide bars 43 and 44 are thin round bars.

The push bars disclosed in the above-mentioned prior art are wide band and face-contacting band plates, especially when the mask sheet is conveyed by the second folding step after the first folding and when the mask sheet completely folded out is subjected to a large frictional force As a result, the received transfer resistance may interfere with the smooth transfer of the folded mask sheet, and the folded state may not be disturbed.

On the other hand, the guide bars 43 and 44 are arranged at the same position as the folding width of the mask sheet by 1/3 as in the conventional pressing bar, but the space between the guide bars 43 and 43 is empty, The resistance received by the mask sheet when the folded mask sheet is simultaneously moved out of the guide bars 43 and 44 can be transferred smoothly to the subsequent feeding station, The folded state of the mask sheet can be maintained even without pressing means.

6, when the lifting plate 32 is lowered by the lifting plate cylinder 32, all the loads of the lifting plate including the sheet separating rod 34 are lowered together. The bottom dead center is the time when the claw 36 of the separating bar 34 is in contact with the upper surface of the uppermost mask sheet a in the mask sheet of the mask sheet lift 50 and the claw 36 is in contact with the contact pressure at this time Take the topmost mask sheet (a).

Then, the separation rod driving means 35 rotates the separation rod 34 counterclockwise. The rotation angle of the separation rods 34 corresponds to the advancing stroke of the piston by the separation rod driving means 35. The mask sheet (a) is wound by the amount corresponding to the rotation of the separation rod (34) while the tip end portion is caught on the hook (36).

2 and 3, in the above-described situation, the lifting plate 33 is pulled up by the lifting plate cylinder 32 to separate the mask sheet a, and the lifting plate 32 is lifted up by the lifting cylinder 37 The mask sheet a is lowered on the belt conveyor 20 by the lifting plate 33 lowered by the lifting plate cylinder 32 and separated by the separating rod driving means 35 When the rod 34 is reversely rotated

The mask sheet (a) falls off the hook 36.

The belt conveyor 20 is operated to move the mask sheet a to the folding station S2 at the moment when the separating bar 34 ascends and returns by the lifting plate cylinder 32. [

The elevating cylinders 41 and 42 immediately operate as soon as the mask sheet a is detected by a photosensor which is not shown in the folding station S2 to descend the guide rods 42 and 43, ).

7 and 8, the compressed air is blown from the first air nozzle 45 to fold the mask sheet portion a1 outside the one guide bar 43, and the second air nozzle 46 blows compressed air, The outer mask sheet portion a2 of the bar 44 is folded.

In this process, the mask sheet portion a1 is brought into close contact with the mask sheet portion a3 between the both side guide bars 43 and 44 and the outer end thereof is hid inside the guide bar 43 to form the second air nozzle 45, When the compressed air is blown in, it is not influenced by it. Therefore, a pressing means for preventing the folded mask sheet portion a1 from being lifted is unnecessary.

Since the mask sheet portion a2, which is folded later, is first brought into close contact with the folded mask sheet portion a1, there is no need to prevent lifting of the mask sheet portion a2.

After the mask sheet a is folded into three sections, the belt conveyor 20 is again operated to convey the folded mask sheet a 'to the draw-in station S3, and the elevating cylinders 41 and 42 guide the guide bars 42, 43).

Thereafter, as shown in FIG. 2, the pouch inserting means 70 is inserted into the lower portion of the pull-in station S3 and is detected by a photosensor (not shown) provided on the pull- The pulling means 60 is operated in accordance with a signal obtained by lowering the length of the folded mask sheet a '

After the entry, the pouch is taken out and sealed, and the completed mask pack is taken out of the air.
