As seen above, masks for wearing on the human body are used to prevent substances to be filtered, such as fine dust, droplets, and bacteria, from entering the human respiratory tract. In the past, there has been a continuous demand for masks in health facilities such as hospitals, and due to the increase in yellow dust and fine dust, there has been a significant demand for masks among general consumers. In addition, in addition to infectious diseases such as MERS and SARS, the recent COVID-19 pandemic has progressed worldwide, leading to an explosive increase in the demand for masks. Due to the increased health awareness of the global population, steady demand for masks is expected to continue even when COVID-19 stabilizes.

Despite this demand for masks, improvements in mask production facilities are minimal. No active improvements have been made to mask production facilities over the past 20 years. However, due to the global COVID-19 epidemic in 2020, as the excellent quarantine function of masks has come into the spotlight, the demand for equipment to produce masks has also surged. However, as a result of hastily introducing and using designs for mask production facilities that had been neglected for improvement for a long time, many mask production companies ended up spending additional operating manpower/cost on various operational issues, including responding to frequent breakdowns, thereby reducing profitability. I am experiencing this worsening problem. However, considering, for example, the increasing consumer awareness of masks due to COVID-19 and the selling price of masks, it is expected that demand for mask production will continue, and it is expected that the demand for mask production will continue to reduce operational losses on mask production facilities. is required.

Although COVID-19 is currently entering a phase of gradual calming down through the efforts of each country, there is a possibility that leaf diseases will become prevalent again in the future, so preparations for this will also be necessary. Considering awareness of responses to yellow dust and fine dust, etc., there will be a future demand for mask production. is expected to continue to be maintained. Accordingly, the opinion that national or local governments should have emergency mask production facilities in preparation for mask shortages in the event of a resurgence of infectious diseases is gaining ground.

Equipment for the production of masks can generally be divided into a mask body molding device that forms the main body of the mask, and a device for joining ear straps to the produced mask body. Considering that the processing speed of the ear strap bonding device is relatively low compared to the production speed of the mask body forming device, which generally forms the mask body based on fabric and filter wound in roll form, a single mask body forming device and a plurality of ear straps are used. Mask production equipment including a combination of bonding devices has been mainly utilized. However, this type of combination includes multiple combination types in order to expand production facilities to meet the ever-increasing demand for masks, making it difficult to design the layout of the entire production facility, space utilization is also low, and management supervision is required. There is also the problem of requiring significant human resources for human resources.

More specifically, mask equipment can be classified as a type of R to R equipment, and major R to R equipment companies have also developed high-speed (e.g., over 400 sheets/min) machines, but the pre- and post-processes do not keep up with the mask production speed. There are many cases where it is useless. Additionally, in the case of high-speed production machines, there are many limitations to slowing down production until COVID-19 is suppressed and other infectious diseases become prevalent again.

In relation to this, Figure 1 is an exemplary diagram of a mask mass production facility according to the prior art. As shown in FIG. 1, the basic unit 100 of the mask production equipment for mask production may include a mask body molding device 110 for manufacturing the main body of the mask and a plurality of ear strap bonding devices 151 and 152. there is. Typically, the working speed of the main body molding 110, which forms the mask body using fabric and filters wound in a roll, is faster than the processing speed of the ear strap joining devices 151 and 152, so a large number of ear strap joining devices are used. can be placed. However, even for the basic unit (100) of this mask production facility, the number of masks that one unit can produce within a given time is limited. Therefore, for mass production of masks, a plurality of basic units 100 of such mask production equipment are provided. According to the layout 10 according to the prior art, as shown in FIG. 1, the basic units 100 ) Even if you try to maximize space utilization in order to place a plurality of them, space waste is bound to occur.

For example, in the case of installing 10 sets of basic units 100 in a space of 25 m × 15 m as shown in FIG. 1, the maximum production speed may be limited to 1000 sheets/min. In relation to this, if a reason for downtime occurs, such as failure, inspection, or material replacement of any one of the main body molding devices (110), the operation of the entire basic unit (100) is stopped, and the ear strap joining devices (151, 152) are also work will stop. Conversely, if a reason for stopping the operation of the ear strap joining devices (151, 152) occurs, the main body molding device (110) also stops working.

In addition to limitations in production speed, the operating manpower for the mask production facilities is also excessively required. Since the arrangement or location of the main body molding device 110 and the ear strap joining devices 151 and 152 are different, the movement of operating personnel for inspection may be inefficient and more personnel may have to be invested. Even if personnel with expertise in both the main body molding device 110 and the ear strap joining devices 151 and 152 are employed to reduce the number of workers, it will inevitably take longer in terms of work efficiency.

In addition, in the conventional layout as shown in FIG. 1, for example, the material input positions for the main body molding device 110 and the ear strap joining devices 151 and 152 are different, and the complexity of the position difference is high. , it is not possible to automate the supply of raw materials such as fabric, filters or ear straps. In addition, since the output positions of the ear strap bonding devices 151 and 152 for the completed mask are also different and the complexity of the position difference is high, automation of the mask packaging equipment is also impossible.

The multi-unit integrated mask production system according to an embodiment of the present invention is intended to solve such problems, and improves speed, operational convenience and elasticity, system automation and scalability, etc. by rearranging the conventional old and unreasonable modular production line. It is a system that can see improvements in many areas, and at the same time, it can be an exemplary operation example of a smart factory.

In relation to this, Figure 2 is a conceptual diagram of a multi-unit integrated mask production system according to an embodiment of the present invention. As shown in FIG. 2, according to an exemplary layout of a multi-unit integrated mask production system 200 according to an embodiment of the present invention, a body forming unit 210 including a plurality of body forming devices and a plurality of joints It is possible to implement a multi-unit integrated mask production system 200 based on a multi-multi smart factory by organically combining the ear strap joint 250 including the unit through the transfer unit 230. As shown in FIG. 2, for example, it can be configured to have a higher production rate of 1000 sheets/min or more within a much smaller installation space than the production facility with a layout according to the prior art of 14 m × 14 m. there is.

For example, in the multi-unit integrated mask production system 200 as shown in Figure 2, a device with a main body production speed of 100 sheets/min and an ear strap bonding processing speed of 150 sheets/min is used, resulting in a total of 1000 sheets/min. It is possible to implement a mask production system of more than 100%. It occupies only about 2/3 of the installation space compared to the layout according to the prior art as shown in FIG. 1, and can have an aligned logistics line. In addition, it is easy to further expand the main body molding device or joining unit, and it is possible to significantly reduce the number of specialized manpower for mechanical device management. By minimizing the movement of workers, it is possible to operate with only about 1/3 of the operating personnel compared to before. In addition, as shown in Figure 2, the material input positions for the main body molding devices or joining units can be lined up, making it possible to automate the supply of raw materials such as fabric, filters, or ear straps (Material Auto Feeding). there is. In addition, the output position of the ear strap bonding device for the completed mask can also be aligned, so automation of the mask packaging equipment (to Auto Packing) can also be implemented.

The multi-unit integrated mask production system according to one aspect of the present invention may be configured so that the entire system does not stop even when raw materials such as body fabric, ear straps, etc. are periodically replaced. Additionally, the system does not stop even when some equipment is maintained. For example, according to one aspect of the present invention, the main body process and the ear string process are separated and the two systems are organically integrated (M2M), so that the operation of the entire system is not interrupted even when some equipment is stopped. .

Additionally, the multi-unit integrated mask production system according to one aspect of the present invention can implement a multi-to-multi (M2M) work flow or communication system. For example, the mask body produced in the body molding device can be automatically distributed to the corresponding ear strap jointer according to programmed situations. Additionally, according to one aspect, the speed of the body molding device may be automatically controlled according to the processing speed of the ear strap joining unit. Furthermore, various types of masks, such as panel/3D, large/small, can be configured to be automatically distributed to appropriate ear strap bonding units by the transfer system.

Here, according to one aspect of the present invention, a Transformable Ear loop Bonding System (Auto changing) may be applied. For example, the ear strap bonding unit can be set to correspond to anything from a panel type mask to a 3D (fish type) mask with just a touch operation. Additionally, minor changes to other detailed models can be set to be joined according to pre-memorized dimensions.

Meanwhile, as discussed above, according to the multi-unit integrated mask production system according to one aspect of the present invention, it is possible to implement an optimized machine layout. For example, the movement lines of workers/raw materials/finished products can be organized in an arrangement that suits logistics. Therefore, it is possible to allow more room in the arrangement of work personnel based on organized movement lines. In addition, it can be easily connected to factory automation (Smart Factory) functions such as automatic fabric replacement system and automatic packaging system.

Additionally, even minor changes to the detailed model can be configured to be joined according to pre-memorized dimensions.

For example, according to one aspect of the present invention, the main control unit 270 provided in the multi-unit integrated mask production system according to one embodiment of the present invention may be implemented by a computing device including a processor and memory. The memory may be configured to store data, and the processor may be configured to perform operations or generate instructions for controlling components.

Even for the same mask type, the length of the attached ear straps may vary depending on the preference of the consumer or manufacturer. In this case, the first subtype and the second subtype can be separated for the same mask body type so that the ear strap lengths for the corresponding subtypes are stored differently.

The input unit of the main control unit 270 may be configured to receive a mask type setting instruction for a specific bonding unit, for example, at least one of the first bonding unit and the second bonding unit, from the user. The mask type setting instructions may include, for example, selection information for a particular mask body type.

Therefore, the main control unit 270, based on at least one of the mask type information included in the mask type setting instruction input from the user through the input unit and a plurality of setting information stored in the memory, the first bonding unit and the second bonding unit It may be configured to set a mask type for at least one of.

According to one aspect, the mask type setting instruction may include information about at least one of the ear strap joining position or spacing, or the length of the ear strap being joined, according to the setting information acquired by the main control unit 270. The ear strap joint 250 or a specific joint unit can set the mask body type based on this (step 840) and change the settings to suit the corresponding mask body. The ear strap bonding unit 250 or a specific bonding unit may transmit mask type setting completion information indicating that the mask type setting has been completed to the main control unit 270 (step 850). Through this procedure, for example, after the first bonding unit is set to perform ear strap bonding to the first type of mask body, the main control unit 270 controls the first bonding unit to perform the first bonding unit. The transfer unit 230 can be controlled to transfer one type of mask body to the first mixing unit as above.

Meanwhile, in this specification, the 'length direction' of the mask body may refer to the direction from one side of the mask body where the ear straps can be attached to the other side where the other ear straps can be attached. For example, assuming that a mask is worn on the human body, the 'length direction' of the mask body may mean the left and right directions. Additionally, in this specification, the 'width direction' of the mask body may mean a direction perpendicular to the 'length direction'. For example, assuming that a mask is worn on the human body, the 'width direction' may mean the up and down direction.

When the mask body is input toward or output from a predetermined device or unit, input or output in the 'longitudinal direction' of the mask main body may mean that the mask main body is moved in the longitudinal direction to be input or output. . Therefore, when input or output is made in the 'length direction' of the mask body, the left or right end of the mask body may be input or output while leading the mask body.

It may include a plurality of main body grip assemblies 1400.

The rotation plate 1320 may be configured to rotate around the rotation center 1310. As the rotation plate 1320 rotates in this way, each of the plurality of body gripping assemblies 1400 moves the rotation plate 1320 along a circular movement trajectory including the first position 1301 and the second position 1302. It may be configured to move in the circumferential direction.

Each of the plurality of body gripping assemblies 1400 may be configured to grip the mask main body at the first position 1301 and release the mask main body gripped at the second position 1302. The main body gripping assembly 1400-1 located at the first position 1301 is configured to grip one end in the first direction of the mask main body in the first direction input from the main body input member 1100 to the first position 1301. The body gripping assembly 1400-2 located at the second position 1302 may be configured to release the mask body it is holding and deliver the mask body arranged in the second direction to the body output member 1900. there is. For example, the mask body is entered into the first position 1301 in the longitudinal direction, one end in the longitudinal direction is held by the body holding assembly 1400, and moves together according to the rotation of the rotary plate 1320 to be held in the second position. (1302) It may be released in a state oriented in the width direction.

As shown in FIGS. 17 to 20 , the rotating member 1300 may further include a sensor unit 1330 that detects whether the mask body is input to the first position 1301. The sensor unit 1330 may include, for example, an optical sensor configured to detect whether or not the mask body is input, but the sensor included in the sensor unit 1330 of the present invention is not limited thereto, and the first position 1301 It should be understood that any type of sensor capable of detecting whether the mask body is being input may be used. As shown in FIGS. 17 to 20, the sensor unit 1330 may be configured to include a guide unit formed so that the height of separation from the conveyor is lowered according to the direction of movement of the mask body to guide the input mask body.

The rotating member 1300 according to an embodiment of the present invention may be configured to operate in conjunction with the sensor unit 1330 determining that the mask body has been input into the first position 1301. For example, the body gripping assembly 1400-1 located at the first position 1301 is configured to grip the mask body in response to the sensor unit 1330 determining that the mask body has been entered into the first position 1301. Configured, the rotation plate 1320 moves each of the plurality of body gripping assemblies 1400 by a certain distance in the circumferential direction in response to the sensor unit 1330 determining that the mask body has been input to the first position 1301. It may be configured to rotate so as to. The main body gripping assembly 1400-2 located at the second position 1302 may be configured to release the mask main body being held in conjunction with the rotation of the rotation plate 1320 as described above.

According to one aspect, the rotation angle at which the rotation plate 1320 rotates in response to the sensor unit 1330 determining that the mask body has been entered into the first position 1301 is determined by the installation of the plurality of body holding assemblies 1400. It can be determined depending on the number. For example, if four body gripping assemblies 1400 are installed on the rotation plate 1320, the rotation angle of the rotation plate 1320 according to the input of the mask body may be 90 degrees. Alternatively, for example, if eight body gripping assemblies 1400 are installed on the rotation plate 1320 as shown in FIGS. 17 to 18, the rotation angle of the rotation plate 1320 according to the input of the mask body is 45 It could be degrees.

Figure 21 is a side view of the body gripping assembly of the rotating member of Figure 18; Hereinafter, with further reference to FIG. 21, the body gripping assembly 1400 according to an embodiment of the present invention will be described in more detail.

18 to 21, according to one aspect of the present invention, each of the body gripping assemblies 1400 may include a pressing portion 1410 and a protruding portion 1430. For example, the pressing unit 1410 may press the mask body in a direction approximately perpendicular to the rotation plate 1320 so that the mask body is held. According to one exemplary embodiment, the pressing unit 1410 is pressed in a direction perpendicular to the rotating plate 1320 so that the pressing unit 1410 and the rotating plate 1320 come into contact with each other, so that the pressing unit 1410 and the rotating plate 1320 are pressed. ) may be configured to hold the mask body with one end interposed between them.

The protrusion 1430 may be combined with the pressing unit 1410 and configured to move linearly in a direction approximately perpendicular to the rotating plate 1320 as one body with the pressing unit 1410. For example, as shown more specifically in Figure 19 or Figure 20, the pressing unit 1410 may be disposed on the rotating plate 1320, and the pressing unit vertical shaft 1420 coupled to the pressing unit 1410 ) may extend through the rotation plate 1320 to the bottom of the rotation plate 1320. The protrusion 1430 is coupled to the pressing unit vertical shaft 1420 extending below the rotating plate 1320, so that the pressing unit 1410 and the protruding unit 1430 are integrated and move linearly in a direction approximately perpendicular to the rotating plate 1320. It can be configured to do so.

According to one aspect of the present invention, the protrusion 1430 protrudes in the direction of the rotation center 1310 of the rotating plate 1320 in relation to the pressing portion 1410 or the pressing portion vertical shaft 1420 of the main body gripping assembly 1400. It can be configured as follows.

Here, according to one aspect of the present invention, the upward or downward movement of the pressing portion 1410 and/or the protrusion 1430 in the vertical direction with respect to the rotating plate 1320 is, for example, caused by the rotation of the rotating plate 1320. It may be implemented by latch parts 1871 and 1872 configured to move linearly in a direction perpendicular to the rotation plate 1320 based on at least one cam 1851 and 1852 configured to rotate in conjunction with each other.

For example, as shown in FIG. 19 or FIG. 20, the body gripping assembly 1400 located at the first position 1301 allows the pressing portion 1410 to grip the mask body by the first latch portion 1871. It can be configured to move to a location.

More specifically, the first latch portion 1871 is configured to move linearly in a direction perpendicular to the rotation plate 1320, for example, based on the first cam 1851 configured to rotate in conjunction with the rotation of the rotation plate 1320. It can be. As the first cam 1851 rotates, the first cam shaft 1861, the first end of which is rotatably coupled to the first cam 1851, moves along a predetermined trajectory, and the first cam shaft 1861 moves along a predetermined trajectory. The first latch portion 1871 to which the second end is rotatably coupled may be configured to move upward or downward by the trajectory movement of the first cam shaft 1861. The first latch portion 1871 may move upward or downward along the first latch rail 1881.

With the main body gripping assembly 1400 positioned in the first position 1301, the first latch portion 1871 contacts the protrusion 1430 to move the protrusion 1430 in the first vertical direction, thereby creating a pressing portion ( 1410) may be moved in a first vertical direction toward the rotation plate 1320. As exemplarily shown in FIG. 19 , with the body gripping assembly 1400 positioned, for example, in the first position 1301, the first latch portion 1871 moves downward to lower the protrusion 1430. By moving, the pressing portion 1410 moves downward toward the rotating plate 1320 to grip the mask body.

Meanwhile, for example, as shown in FIG. 19 or FIG. 20, the body gripping assembly 1400 located at the second position 1302 allows the pressing portion 1410 to grip the mask body by the second latch portion 1872. It may be configured to move from a position to release the mask body.

More specifically, the second latch portion 1872 is configured to move linearly in a direction perpendicular to the rotation plate 1320, for example, based on the second cam 1852 configured to rotate in conjunction with the rotation of the rotation plate 1320. It can be. As the second cam 1852 rotates, the second cam shaft 1862, the first end of which is rotatably coupled to the second cam 1852, moves along a predetermined trajectory, and the second cam shaft 1862 moves along a predetermined trajectory. The second latch portion 1872, the second end of which is rotatably coupled, may be configured to move upward or downward by the trajectory movement of the second cam shaft 1862. The second latch portion 1872 can move upward or downward along the second latch rail 1882.

With the body gripping assembly 1400 positioned in the second position 1302, the second latch portion 1872 contacts the protrusion 1430 to move the protrusion 1430 in a second vertical direction opposite to the first vertical direction. By moving to , the pressing unit 1410 can be moved in the second vertical direction, which is a direction away from the rotating plate 1320. As exemplarily shown in FIG. 20 , with the body gripping assembly 1400 positioned, for example, in the second position 1302, the second latch portion 1872 moves upward to raise the protrusion 1430. By moving, the pressing portion 1410 moves upward in a direction away from the rotating plate 1320, thereby releasing the mask body being held.

According to one aspect of the present invention, at least one of the protrusion 1430, the first clasp portion 1871, or the second clasp portion 1872 is directed toward the rotation center 1310 of the rotating plate 1320 and is positioned at the rotating plate 1320. A roller unit configured to rotate based on a roller rotation axis orthogonal to the rotation axis may be provided. For example, as shown in FIGS. 18 to 21, the protrusion 1430 is directed toward the rotation center 1310 of the rotation plate 1320 and rotates about a roller rotation axis orthogonal to the rotation axis of the rotation plate 1320. It may be configured as a configured roller unit. Accordingly, even when the protrusion 1430 is in contact with the first latch part 1871 or the second latch part 1872, the rotation plate 1320 can be easily rotated by the roller part rotating.

Meanwhile, according to one aspect of the present invention, the pressing portion 1410 of the main body gripping assembly 1400 moved to the gripping state by the first latch portion 1871 in the first position 1301 is moved to the second position 1302. It can maintain its grip state until it moves to . In addition, the pressing portion 1410 of the main body gripping assembly 1400, which has been moved from the second position 1302 to the released state by the second latch portion 1872, is moved back to the first position by rotation of the rotating plate 1320. The released state can be maintained until moved to 1301). According to one aspect, maintenance of the gripped state and/or the released state may be implemented by an elastic member, such as an elastic spring 1460, for example.

In relation to this, referring to FIG. 21 , each of the plurality of body gripping assemblies 1400 may further include a pressing unit shaft support 1440, a pressing unit shaft 1450, and an elastic spring 1460. As shown in FIG. 21, the pressing unit shaft support 1440 may be arranged to be fixedly coupled to the rotating plate 1320, and may be formed integrally with the rotating plate 1320.

For example, the pressing unit shaft 1450 may be configured such that one end is rotatably connected to the pressing unit 1410 and the other end is rotatably connected to the pressing unit shaft support 1440. For example, the pressing unit shaft 1450 has one end connected to the pressing unit 1410 so as to be rotatable based on the pressing unit rotational coupling point 1415, and is connected to the pressing unit shaft support rotational coupling point 1445. The other end may be connected to the pressing portion shaft support 1440 so as to be rotatable.

As shown in FIG. 21, an elastic spring 1460 may be disposed between the rotational engagement point 1515 of the pressure shaft and the rotational engagement point 1445 of the shaft support. The elastic spring 1460 may have a predetermined elastic force or more. Therefore, based on the elastic force of the elastic spring 1460, the pressing portion 1410 keeps the first clasp portion 1871 or the second clasp portion 1872 even if the contact between the protrusion 1430 and the protruding portion 1430 is released. It may be configured to maintain the position moved in the first direction or the second direction by (1871) or the second latch portion (1872). The elastic force of the elastic spring 1460 has a larger value than the elastic force for maintaining the gripping and/or released state of the pressing part 1410, but the elastic force according to the first latch part 1871 or the second latch part 1872 It can be set to a size that does not limit the change in position of the pressing unit 1410.

Referring again to Figures 12-17, a power transmission member 1800 is shown. According to one aspect of the present invention, one or more of the main body input member 1100, the rotating member 1300, and the main body output member 1900 are interconnected by operating based on power transmitted from the power transmission member 1800. It can work. The power transmission member 1800 may include, for example, a power source 1810, as shown in FIGS. 12-17. The power source 1810 may be, for example, but is not limited to an electric drive motor.
