Description

Technical Field

[0001] The invention relates to a packaging device for independently packaging cotton pad cosmetics in small bags. Background Art

[0002] Generally, cosmetic cotton pads are made by cutting 100% pure cotton non-woven fabric along the length direction, and then cutting a certain length of cotton pads along the longitudinal direction to produce rectangular cosmetic cotton pads. The cosmetic cotton pads produced in the above manner are usually sold as dry products. Users can wet the dry cosmetic cotton pads with makeup remover, toner, essence and other lotions and apply them to the skin or use them as facial masks. However, when used in an external environment other than home or company, it is actually cumbersome and inconvenient to carry cosmetic cotton pads and lotions and use them after wetting the cosmetic cotton pads with lotions. Therefore, some cosmetic cotton pads that are not in a dry state have recently been introduced. Instead, they are products that are sold after a certain number of cosmetic cotton pads are wetted with various lotion liquids and stored in a cylindrical container. When using multiple wet cosmetic cotton pads stored in a cylindrical container as described above, there is also the problem of inconvenience in carrying the container. Moreover, because it is necessary to open the lid and tear off the wet thin cotton pads by hand when using them, the remaining cotton pads will be contaminated, and the remaining cotton pads may become dry and unusable due to forgetting to cover the lid.

[0003] In order to compensate for the shortcomings of cotton pad cosmetics packaged in barrel-shaped containers as described above, it is possible to improve the packaging of cotton pad cosmetics into independent small bags. However, the cut cotton pad materials need to be located at the correct positions in the packaging film and perform continuous processes (vertical joining of the packaging film, horizontal joining, filling of lotion, horizontal joining, vertical cutting of the small bags, and horizontal cutting) under the above-mentioned conditions. However, it is very difficult to accurately align the raw cotton pads of the cotton pads into the packaging film made of polyolefin resin (mainly linear low-density polyethylene plastic (LLDPE) or low-density polyethylene plastic (LDPE)) in order to effectively complete thermal bonding and to improve the stability of the packaging film process.

[0004] <Patent document> KR101470134 (published on December 5, 2014) "Rotary cutting method for manufacturing and packaging cosmetic cotton"

[0005] The prior art disclosed in the <Patent Document> also relates to a continuous cosmetic cotton manufacturing and packaging device, but in the cosmetic cotton packaging method, each cosmetic cotton is not individually packaged in a packaging film, but a certain number of stacked cosmetic cottons are packaged as a bundle.

[0006] Therefore, there is a particular need for a packaging device that can stably supply a specified length of cosmetic cotton material cut along the longitudinal direction or independently package the cut cosmetic cotton material pads and improve the stability of the process, while also being able to align and arrange the independently packaged small bags on a conveyor belt and automatically count them.

[0030] The present invention adopts a structure in which the rollers on one side of a pair of material pad supply rollers and a pair of packaging film supply rollers are fixed respectively while the rollers on the other side are pressurized by a separate elastic pressure component (and an elastic adjustment component).

[0044] Next, the preferred embodiment of the small bag independent packaging cotton pad type cosmetic packaging device for improving the process stability of the cosmetic cotton material pad according to the present invention will be described in detail with reference to the accompanying drawings. It should be noted that for the same components in the accompanying drawings, the same number is used in all positions as much as possible. Unless otherwise defined, the meaning of all terms in this specification is the same as the general meaning of the corresponding terms commonly understood by personnel with general knowledge of the technical field to which the present invention belongs, and when there is a conflict with the meaning of the terms used in this specification, the definition used in this specification is followed. Throughout the specification, when it is recorded that a certain part "includes" a certain component, unless otherwise clearly stated to the contrary, it does not mean that other components are excluded, but that other components may also be included. In addition, terms such as "... part" and "... module" recorded in the specification refer to units that process at least one function or action, which can be implemented by hardware or software or a combination of hardware and software.

[0045] See also Figures 1 to 4 According to one embodiment of the present invention, a small bag independently packaged cotton pad cosmetic packaging device for improving the process stability of cosmetic cotton material pads, its basic structure may include: a cosmetic cotton supply unit 1, which supplies cosmetic cotton to be accommodated in the packaging film; a packaging film supply unit 3, which supplies packaging film for packaging the cut cosmetic cotton material pads; and a small bag arrangement unit 5, which aligns and arranges the cut small bags on the conveyor belt.

[0046] First, a brief description is given of the process of placing a cotton pad in a packaging film and manufacturing it into a small bag (referring to a product form in which each cotton pad is individually packaged using a packaging film, which is not shown in the attached drawings). When a cotton pad cut into a certain unit size (referring to a cotton pad in which the cotton pad material is cut into a certain (horizontal and vertical) size) is placed at a certain interval in a pair of packaging film discs forming the front and back sides, the vertical parts of the two sides of the packaging film and the horizontal parts of the lower end of the packaging film are sealed along the outer periphery of the cotton pad, and a liquid product (such as makeup remover, toner, lotion, and essence, etc.) that meets the purpose is injected into the interior, and then the horizontal part of the upper end of the packaging film is sealed, and then the overall disc-shaped packaging film is cut longitudinally and transversely, thereby manufacturing an independent small bag containing a cotton pad in the packaging film.

[0047] To this end, the cosmetic cotton supply unit 1 is a component that serves to supply / seal / cut cosmetic cotton material (generally speaking, the disc-shaped cosmetic cotton material is unrolled and supplied in a rolled state, which is not shown in the accompanying drawings) and manufacture and supply cosmetic cotton material pads that need to be individually packaged. The packaging film supply unit 3 is a component that serves to supply / seal / cut packaging film for packaging the cut individual cosmetic cotton material pads and manufacture and supply independent small bags. The small bag alignment unit 5 is a component that serves to align and arrange the cut small bags on the conveyor belt.

[0048] Next, the general working process of each component is described. First, the cosmetic cotton supply unit 1 may include: a cosmetic cotton material supply part, which supplies cosmetic cotton material wound into a roll form (at this time, the supplied cosmetic cotton material can be a layer, but two to three layers or more of cosmetic cotton material can also be used); a plurality of cosmetic cotton material guide rollers, which guide the conveying of the cosmetic cotton material unwound from the roll form; a cosmetic cotton longitudinal cutting part, which cuts the cosmetic cotton material supplied in a disc state longitudinally (in the direction consistent with the conveying direction) at a certain interval (usually the width interval of the cosmetic cotton material pad); a guide roller, which drives the cosmetic cotton material cut along the longitudinal direction to move and guide it to the cosmetic cotton transverse cutting part; and a cosmetic cotton transverse cutting part, which cuts the cosmetic cotton material cut along the longitudinal direction transversely at a certain interval (usually the length interval of the cosmetic cotton material pad), thereby producing a cosmetic cotton disc cotton pad of a certain unit size.

[0049] The packaging film supply unit 3 is a component part that supplies / seals / cuts the packaging film for accommodating and packaging the (cut) cosmetic cotton material pads manufactured into a certain unit size at a different position from the cosmetic cotton supply unit, and may include: a pair of packaging film material supply parts, which supply the packaging film in a disc state wound into a roll form from both sides (in order to package the cut cosmetic cotton material pads from both sides, the packaging film is supplied from both sides); a pair of packaging film supply and conveying rollers, which accommodate the cut cosmetic cotton material pads inside by supplying / conveying a pair of packaging films from both sides; a packaging film sealing part, which seals the outer peripheral surface of the packaging film along the outer periphery of the cosmetic cotton material pad in a state where the unit cosmetic cotton material pad is accommodated in the packaging film; a liquid product supply part, which injects the liquid product into the inside of the pair of packaging films in a state where the pair of packaging films are sealed into a bag shape; and a packaging film cutting part (including a packaging film longitudinal cutting part and a packaging film transverse cutting part), which longitudinally and transversely cuts the packaging film disc in a state where the liquid product is injected and sealed, thereby manufacturing an independent small bag containing a cosmetic cotton material pad in the packaging film.

[0050] The small bag alignment unit 5 is a component used to improve the problem that the independent small bags manufactured in the traditional way directly fall onto the conveyor belt and are arranged disorderly on the conveyor belt for transportation. It is a component that aligns and arranges the cut small bags on the conveyor belt.

[0051] In addition, the present invention is particularly intended to solve the problem that occurs in the cosmetic cotton supply unit 1, that is, after the cosmetic cotton material supplied in a disc state is cut at a certain interval (usually the width interval of the cosmetic cotton material pad) along the longitudinal direction (the direction consistent with the conveying direction), the cosmetic cotton material cut along the longitudinal direction is conveyed and guided (supplied) to the transverse cutting portion of the cosmetic cotton, such as Figure 3 As shown, in the conventional method, a pair of guide rollers 400 that are simply arranged in parallel are used to align the cosmetic cotton material cut along the longitudinal direction between the pair of guide rollers 400 for conveying and supplying. However, under the conventional structure as described above, there will be no major problems in always supplying cosmetic cotton materials of a certain thickness, but it is very difficult to always maintain a uniform thickness of the cosmetic cotton material throughout the material, especially when the next cosmetic cotton material is conveyed after completing the conveyance of one cosmetic cotton material (generally speaking, in the case as described above, the thickness at the connection part of each material will increase to 2 times). In the conventional structure, the cosmetic cotton material cannot be smoothly conveyed and supplied. The purpose of the present invention is to solve the above-mentioned problems, which will be described in detail below.

[0052] In order to improve the problems occurring in the conventional pair of guide rollers 400 for conveying the longitudinally cut cosmetic cotton material and supplying it to the transverse cutting portion of the cosmetic cotton as described above, the present invention proposes a new structure that can actively cope with the thickness changes of the cosmetic cotton material being supplied.

[0053] For this purpose, see Figure 4 , the cosmetic cotton supply unit 1 comprises: a cosmetic cotton material guide roller 110, which supplies a certain length of cosmetic cotton material cut along the longitudinal direction (not shown); at this time, the cosmetic cotton material guide roller 110 comprises: a first guide roller 111 and a second guide roller 112, which clamp the cosmetic cotton material cut along the longitudinal direction (not shown) from both sides and supply a certain length; the rotating axes of the first guide roller 111 and the second guide roller 112 are connected by a separate second rotating linkage device 120, so that the two are linked to each other and rotate synchronously, and the second guide roller 112 is fixed and the first guide roller 111 is composed of a structure that is pressurized and moved by a separate second elastic pressure component 130, so that the thickness of the cosmetic cotton material cut along the longitudinal direction (not shown) being transported can be flexibly adjusted and a certain length of cosmetic cotton material cut along the longitudinal direction (not shown) can be stably supplied.

[0054] The cosmetic cotton material guide roller 110 is configured to supply a certain length of the longitudinally cut cosmetic cotton material (not shown) to its subsequent process, i.e., the transverse cutting part of the cosmetic cotton during the conveying process. Specifically, it adopts a structure including a first guide roller 111 and a second guide roller 112 that clamp the longitudinally cut cosmetic cotton material (not shown) from both sides and supply a certain length.

[0055] In addition, in the first guide roller 111 and the second guide roller 112, a separate rubber coating A may be formed on the outer peripheral surface of the roller in order to more stably clamp the cosmetic cotton material (not shown) cut along the longitudinal direction. The rubber coating A formed at this time is to more stably clamp the cosmetic cotton material (not shown) in contact with its surface through the friction force of its surface, etc., and the raw material of the rubber material is used as its basic raw material, and the compound raw material with functional additives for strengthening the friction force etc. mixed inside can be used.

[0056] The second rotating linkage device 120 connects the rotating axes of the first guide roller 111 and the second guide roller 112 working in pair so that the pair of first guide rollers 111 and the second guide roller 112 are linked to each other and rotate synchronously. The second guide roller 112 connected to a separate driving unit (not shown) for rotation can be linked to and synchronized with the first guide roller 111, thereby supplying the conveyed and supplied cosmetic cotton material (not shown) to the subsequent process (cosmetic cotton transverse cutting unit) at an accurate speed and a certain length.

[0057] As an embodiment of the second rotation linkage device 120, a gear connection structure can be used to connect the rotation axes of the first guide roller 111 and the second guide roller 112. In addition, various structures such as timing belts that can connect multiple rotation axes and synchronize their rotation can also be used.

[0058] The second elastic pressure component 130 is used to pressurize the first guide roller 111 that rotates in conjunction with the fixed second guide roller 112. As mentioned above, there will be no major problems when a certain thickness of cosmetic cotton material (not shown) is always supplied, but it is very difficult to always maintain a uniform thickness of the cosmetic cotton material (not shown) throughout the material, especially when the next cosmetic cotton material is continued to be delivered after the delivery of one cosmetic cotton material is completed (generally speaking, in the above case, the thickness of the connection part of each material will increase to 2 times). Under the traditional structure, the cosmetic cotton material (not shown) cannot be smoothly delivered and supplied. Only by flexibly adjusting the thickness of the locally changed cosmetic cotton material can the above problem be solved. In order to solve the above problem, the present invention adopts a structure in which the second guide roller 112 is fixed and the first guide roller 111 is pressurized by the second elastic pressure component 130, so that the thickness of the supplied cosmetic cotton material (not shown) can be flexibly adjusted, and thereby a material supply process of stably supplying a certain length of cosmetic cotton material (not shown) cut along the longitudinal direction is realized. As the second elastic pressing member 130 , various structures such as an elastic spring that can apply elastic force may be used.

[0059] The second elastic pressure component 130 may include a single-row adjustment component (not shown) for controlling its elastic force individually, so that the elastic force of the second elastic pressure component 130 can be adjusted for use according to the use environment. That is, basically, in the case of using two-layer cosmetic cotton materials and three-layer cosmetic cotton materials, only by changing the set value of the basic elastic force of the second elastic pressure component 130 can different processes be appropriately handled. Therefore, according to the changes in the use environment as described above, the elastic force of the second elastic pressure component 130 is controlled and adjusted through the elastic adjustment component, so that the device can actively handle changes in various use environments, thereby expanding the application range of the device.

[0060] In addition, the present invention can also improve the problem occurring on the packaging film supply unit 3, that is, although the cut cosmetic cotton material pads 200 need to be respectively arranged at the correct positions in the packaging film 300 and the subsequent processes are performed in the state as described above, it is difficult to accurately arrange the cosmetic cotton material pads 200 in the smooth packaging film 300, thereby resulting in an increase in the defective rate and thus it is difficult to improve the stability of the packaging process as a whole. This problem will be described in detail below.

[0061] First, the structure (connection relationship) of the connection part between the conventional cosmetic cotton supply unit and the packaging film supply unit is as follows. That is, in a state where the end portion of the cosmetic cotton material cut in the longitudinal direction is clamped by the packaging film supply conveyor roller 100 that guides the packaging film supplied from both sides for packaging (that is, the end portion of the cosmetic cotton material cut in the longitudinal direction is clamped by the packaging films on both sides) (see Figure 5 ) performs a transverse cut on the cosmetic cotton material. At this time, due to the characteristics of the packaging film 300, because its surface is smooth, the packaging films 300 on both sides will find it difficult to firmly clamp the end portion of the cosmetic cotton material cut along the longitudinal direction. Figure 5 As shown in the figure, the end of the cosmetic cotton material cut along the longitudinal direction cannot be correctly inserted into the packaging films 300 on both sides. Even if the packaging films 300 on both sides correctly clamp the end of the cosmetic cotton material cut along the longitudinal direction, the cosmetic cotton material may slide due to the cutting force during the transverse cutting of the cosmetic cotton material, resulting in the following situation: Figure 6 The packaging film 300 shown in FIG. 1 is separated from the two sides or as shown in FIG. Figure 7 The problem of obliquely inserting the packaging film 300 into both sides as shown occurs. In particular, the above-mentioned problem occurs not only because the smooth packaging film 300 cannot firmly clamp the end portion of the cosmetic cotton material cut along the longitudinal direction, but also because of the difference in the amount of sliding caused by the difference in thickness of the cosmetic cotton material that locally varies, and it is difficult to properly deal with the above-mentioned problem in the conventional device.

[0062] The present invention proposes a packaging film supply unit structure that can solve the problem caused by the need for the packaging film 300 to directly clamp the end portion of the cosmetic cotton material in the traditional method as described above. It can appropriately adjust the local thickness of the cosmetic cotton material, which will be described in detail below.

[0063] The packaging film supply unit 3 of the present invention is as follows Fig. 9As shown in the figure, it includes: a pair of packaging film supply rollers 320, which supply a pair of packaging films 300 from both sides for packaging the cut cosmetic cotton material pads 200 facing both sides; and a pair of material pad supply rollers 310, which clamp the cut (to be cut) cosmetic cotton material pads 200 from both sides at the front ends of the pair of packaging film supply rollers and supply and convey them into the pair of packaging films 300; at this time, the pair of packaging film supply rollers 320 rotate in conjunction with the supply speed of the supplied pair of packaging films 300, and the pair of packaging film supply rollers 320 and the pair of material pad supply rollers 310 located at the front ends thereof are connected by a separate rotation linkage device 330, so that the pair of material pad supply rollers 310 and the pair of packaging film supply rollers 320 are linked and rotate synchronously, so that the supplied cosmetic cotton material pads 200 can be supplied to the packaging film 300 at an accurate speed.

[0064] First, see Figure 8 In the conventional structure, the packaging film 300 used for packaging the cosmetic cotton material pad directly clamps the end portion of the cosmetic cotton material cut along the longitudinal direction. At this time, due to the characteristics of the packaging film 300, it is difficult to firmly clamp the end portion of the cosmetic cotton material because of its smooth surface, which leads to the problem that the end portion of the cosmetic cotton material cut along the longitudinal direction cannot be correctly inserted into the packaging film 300 on both sides as described above, or the cosmetic cotton material slides due to its cutting force during the transverse cutting of the cosmetic cotton material and detaches from the packaging film 300 on both sides or is obliquely inserted into the packaging film 300 on both sides. In order to solve the above problems from the source, the present invention, as described later, firmly clamps the end portion of the cosmetic cotton material cut along the longitudinal direction by a separate pair of material pad supply rollers 310 at the front end of a pair of packaging film supply rollers 320. At this time, by accurately synchronizing the rotation of the pair of material pad supply rollers 310 and the pair of packaging film supply rollers 320, the supplied cosmetic cotton material pad 200 can be supplied to the packaging film 300 at a correct speed and a certain interval.

[0065] The pair of material pad supply rollers 310 clamp the cut (to be cut) cosmetic cotton material pad 200 from both sides at the front end of the pair of packaging film supply rollers 320 and supply it into the pair of packaging films 300. As mentioned above, the conventional structure of directly clamping the cosmetic cotton material pad 200 by a pair of packaging film supply rollers described later is not adopted. Instead, the cosmetic cotton material pad 200 is clamped from both sides by a separate pair of material pad supply rollers 310 located at the front end of the pair of packaging film supply rollers 320, thereby solving the problem caused by the smooth packaging film directly clamping the cosmetic cotton material pad. That is, because the end portion of the cosmetic cotton material cut along the longitudinal direction is firmly clamped by the pair of material pad supply rollers 310, when the cosmetic cotton material is transversely cut in the firmly clamped state as described above, the cosmetic cotton material (which will become a cosmetic cotton material pad after cutting) can be prevented from sliding or detaching, and because the cut cosmetic cotton material pad 200 is supplied to the pair of packaging films 300 on the pair of packaging film supply rollers 320 in a firmly clamped state, it can be correctly inserted into the packaging film 300.

[0066] In order to enable the pair of material pad supply rollers to clamp the cosmetic cotton material pad 200 more stably and firmly, a separate rubber coating A may be formed on the outer circumferential surface of the material pad supply roller 310 .

[0067] The rubber coating A is intended to more firmly clamp the cosmetic cotton material pad 200 in contact with its surface through the friction force on its surface, and uses rubber raw materials as its basic raw materials, and can also use compound raw materials that have functional additives mixed inside to enhance friction force, etc.

[0068] The pair of packaging film supply rollers 320 supply a pair of packaging films 300 from both sides for packaging the cut cosmetic cotton material pads 200 from both sides (a separate rubber coating can be formed on the outer peripheral surface of the packaging film supply rollers 320 as needed). Each roller in the pair of packaging film supply rollers 320 will guide the packaging films 300 supplied from both sides, so as to package the cosmetic cotton material pads 200 from the front and back sides while accommodating the cut cosmetic cotton material pads 200 inside. In addition, the pair of packaging film supply rollers 320 will rotate in conjunction with the supplied pair of packaging films 300. At this time, it is very important to connect and synchronize the pair of packaging film supply rollers 320 and the pair of material pad supply rollers 310 located at the front end thereof, and for this purpose, the structure of the rotation linkage device 330 described later is required.

[0069] The rotating linkage device 330 connects the rotating shafts of the pair of packaging film supply rollers 320 and the rotating shafts of the pair of material pad supply rollers 310 located at the front end thereof, so that the pair of material pad supply rollers 310 are linked and rotate synchronously with the pair of packaging film supply rollers 320, thereby ultimately making the supply speed of the pair of packaging films 300 and the pair of packaging film supply rollers 320 and the pair of material pad supply rollers 310 linked and synchronized, so that the supplied cosmetic cotton material pad 200 can be supplied to the packaging film 300 at a correct speed and at a certain interval.

[0070] As an embodiment of the rotary linkage device 330, a timing belt can be used to connect the rotating shafts of the pair of packaging film supply rollers 320 and the rotating shafts of the pair of material pad supply rollers 310 located at the front ends thereof. In addition, various structures that can connect multiple rotating shafts and synchronize their rotation can also be used.

[0071] In addition, as mentioned above, because the supplied cosmetic cotton material cannot always maintain a certain thickness, it is necessary to flexibly adjust the thickness of the locally changed cosmetic cotton material in order to solve the problem of the cosmetic cotton material pad being obliquely inserted into the packaging film due to the difference in the thickness of the locally changed cosmetic cotton material. In order to solve the above-mentioned problems, the present invention adopts a structure in which the roller on one side is fixed and the roller on the other side is pressurized by a separate elastic pressure component 340 in the pair of material pad supply rollers 310 and the pair of packaging film supply rollers 320, so that the thickness of the supplied cosmetic cotton material pad 200 can be flexibly adjusted and the packaging film process can be stably performed. As an example, if Fig. 9 As shown, in the pair of material pad supply rollers 310 and the pair of packaging film supply rollers 320, a structure is adopted in which the roller on the left is fixed and the roller on the right is flexibly pressurized by a separate elastic pressure component 340, so that even if the thickness of the supplied cosmetic cotton material pad 200 changes, it can be firmly clamped and conveyed, so that it can be arranged in the packaging film 300 at the correct position and interval.

[0072] The elastic pressure member 340 can apply elastic force and pressurize the rollers on one side of the pair of material pad supply rollers 310 and the pair of packaging film supply rollers 320, and various structures such as elastic springs that can apply elastic force can be used.

[0073] like Fig. 9As shown, an elastic adjustment component 350 for controlling the elastic force of the elastic pressure component 340 may be included on one side of the elastic pressure component 340, so that the elastic force of the elastic pressure component 340 can be adjusted for use according to the use environment. That is, basically, in the case of using two layers of cosmetic cotton materials and three layers of cosmetic cotton materials, only by changing the set value of the basic elastic force of the elastic pressure component 340 can different processes be appropriately handled. Therefore, according to the changes in the use environment as described above, the elastic force of the elastic pressure component 340 is controlled and adjusted by the elastic adjustment component 350, so that the device can actively handle changes in various use environments, thereby expanding the application range of the device.

[0074] Furthermore, in the process of making independent small bags by final cutting of the rows of small bags in the state where the cut cosmetic cotton material pads are arranged in the packaging film in the traditional way, when the rows of small bags are cut longitudinally, the problem of uneven cutting on the left and right sides will occur because the rows of small bags move or tilt to one side, and the said problem will also occur during the transverse cutting, thereby resulting in the problem of reduced efficiency of the overall packaging process and reduced quality of the final product (small bag). The present invention proposes a new structure (construction) that can solve the above-mentioned problems.

[0075] That is, the packaging film supply roller 3 also includes: a punching guide roller (not shown), which clamps and arranges the rows of small bags before cutting the rows of small bags in a state where the cut cosmetic cotton material pads 200 are arranged in the packaging film 300; thereby solving the problem that when the rows of small bags are cut longitudinally and transversely in the traditional way, the rows of small bags move or tilt to one side, which ultimately leads to uneven cutting on the left and right sides.

[0076] The punching guide roller (not shown) clamps (a concept of preventing sliding by applying pressure) and aligns the rows of small bags when cutting, while conveying the rows of small bags in a state where the cut cosmetic cotton material pads 200 are arranged in the packaging film 300 to the subsequent cutting process. The punching guide roller can be located on one side of the row of small bags and pressurize the row of small bags.

[0077] In order to more stably clamp and align the rows of small bags, a separate rubber coating may be formed on the outer peripheral surface of the punching guide roller (not shown). The rubber coating may be considered to have the same structure as the rubber coating described above, and is used to more stably clamp the rows of small bags in contact with its surface by the friction force of its surface. The raw material of the rubber material is also used as its basic raw material, and a compound raw material may be used in which a functional additive for enhancing the friction force is mixed inside.

[0078] In addition, the present invention is particularly intended to solve the problems that occur during the transportation of the finally produced small bags (not shown), that is, after the rows of small bags in which a plurality of cosmetic cotton material pads 200 are sealed at a certain interval in the packaging film 300 material are finally cut longitudinally and transversely by the packaging film cutting part, the final product, i.e., the individual small bags (not shown) will be produced. At this time, the cut small bags (not shown) will directly fall onto the conveyor belt and be arranged in disorder on the conveyor belt for transportation, thereby making it impossible to quickly and accurately count the produced small bags, and also causing delays in subsequent processes such as the final packaging process of the small bags. The purpose of the present invention is to solve the problems mentioned above, which will be described in detail below.

[0079] In order to improve the above-mentioned problem caused by the inability to align and arrange the finally produced small bags on the conveyor belt, the present invention adopts and proposes a new structure for aligning and arranging the finally cut small bags on the conveyor belt after they are individually adsorbed.

[0080] For this purpose, see Fig.10 The pouch alignment unit 5 may include: a rotating adsorption portion 510, which rotates, aligns and arranges the cut pouches (not shown) on a conveyor belt after adsorbing them; and an adsorption guide portion 520, which allows the rotating adsorption portion 510 to easily adsorb the pouches (not shown).

[0081] The adsorption guide 520 can make the rotating adsorption unit 510 (plural adsorption pads 511) easily adsorb a small bag (not shown). Specifically, Fig.10 As shown, in order to enable the multiple adsorption pads 511 of the rotating adsorption part 510 described later to accurately adsorb each small bag in the row of small bags (not shown in the figure), the rear side of the small bags in the row serves as a support rod to prevent the small bags in the row from moving backwards during the adsorption process. The rotating adsorption part 510 (multiple adsorption pads 511) can easily adsorb the small bags (not shown in the figure) with the help of the supporting force provided.

[0082] The rotating adsorption unit 510, after adsorbing the cut small bags (not shown) (preferably, the adsorption of the rotating adsorption unit 510 and the transverse cutting of the rows of small bags are performed almost simultaneously), rotates, aligns and arranges them on the conveyor belt. Specifically, the rotating adsorption unit 510 may include: a plurality of adsorption pads 511, respectively adsorbing and clamping the cut small bags (not shown); a vacuum generator (not shown), generating the vacuum required for the adsorption of each adsorption pad 511; an adsorption pad driving unit 512, used to move the plurality of adsorption pads 511 forward and backward; a rotating shaft 513, used to transmit the plurality of adsorption pads 511 between the adsorption guide unit 520 and the conveyor belt; and a control unit (not shown), used to control the rotating plurality of adsorption pads 511 to be located at an accurate position.

[0083] The multiple adsorption pads 511 respectively adsorb and clamp the multiple small bags (not shown) cut and produced from the rows of small bags. Generally speaking, the number of the multiple adsorption pads 511 should correspond to the number of small bags (not shown) produced in a horizontal column in the row of small bags.

[0084] The vacuum generator generates the vacuum required for each of the plurality of adsorption pads 511 to perform adsorption. The vacuum generator can generate the suction force required for adsorbing a small bag (not shown) in each adsorption pad 511 .

[0085] The adsorption pad driving unit 512 is a driving unit for moving the plurality of adsorption pads 511 forward and backward. In order to make the plurality of adsorption pads 511 adsorb each small bag (not shown) in a row of small bags, the plurality of adsorption pads 511 need to be moved forward and close to the small bag (not shown). After the adsorption is completed, the plurality of adsorption pads 511 are moved backward and rotated in the direction of the conveyor belt. Next, when the vacuum formed on each adsorption pad 511 is eliminated and the suction force is eliminated, the small bag (not shown) adsorbed on each adsorption pad 511 will be placed on the conveyor belt. Next, the plurality of adsorption pads 511 are rotated in the opposite direction so that they are directed toward the small bag (not shown) in the row of small bags that need to be adsorbed again. As the adsorption pad driving unit 512, various structures such as a cylinder that can move forward and backward can be used.

[0086] The rotating shaft 513 is a central rotating shaft for transmitting the plurality of adsorption pads 511 between the adsorption guide 520 and the conveyor belt.

[0087] The control unit is used to control the rotating multiple adsorption pads 511 to be located at an accurate position. First, it controls the rotation angle and speed of the rotating multiple adsorption pads 511 (usually, it can be achieved by controlling the position / operation of the servo motor, etc.), and then the control unit can also flexibly control the loading form of the small bags (not shown) loaded on the conveyor belt and accurately count the number of small bags (not shown) produced. Specifically, the control unit includes: a counting module (not shown), which counts the number of small bags loaded on the conveyor belt through the rotating multiple adsorption pads 511; a rotation interval control module (not shown), which controls the rotation interval of the rotating multiple adsorption pads 511; and a conveying speed control module, which controls the conveying speed of the unidirectional conveyor belt; it can flexibly control the loading form of the small bags (not shown) loaded on the conveyor belt and accurately count them.

[0088] The counting module is used to count the number of small bags loaded on the conveyor belt by rotating the multiple adsorption pads 511. It can be used to count the number of multiple adsorption pads 511 and the number of times the multiple adsorption pads 511 perform actions (rotate), and thereby count the production volume of small bags (not shown) produced within a specific time.

[0089] The rotation interval control module is used to control the rotation interval of the rotating multiple adsorption pads 511, and the conveying speed control module is used to control the conveying speed of the unidirectionally moving conveyor belt. By controlling the rotation interval of the multiple adsorption pads 511 and the conveying speed of the conveyor belt in the manner described above, the loading form of the small bags (not shown) loaded on the conveyor belt can be flexibly controlled. As an example, when the rotation of the multiple adsorption pads 511 is performed 5 times without moving the conveyor belt for a period of time, the small bags (not shown) on the conveyor belt will enter a 5-layer stacked form. On the contrary, when the conveying speed of the conveyor belt is controlled to be accelerated, the small bags (not shown) placed on the conveyor belt can be loaded and conveyed in a form of almost no overlap or no overlap. Through the structure and function of the control unit as described above, the present invention can flexibly control the loading form of the small bags (not shown) loaded on the conveyor belt while accurately counting.
