As discussed above, a mask for human body wear is used to prevent substances to be filtered, such as fine dust, droplets, and bacteria, from entering the respiratory tract of the human body. Conventionally, there has been a continuous demand for masks in health facilities such as hospitals, and the demand for masks among general consumers has been considerable due to the increase in yellow dust and fine dust. In addition to this, in addition to infectious diseases such as MERS and SARS, the demand for masks has exploded as the COVID-19 pandemic has progressed worldwide in recent years. Even if COVID-19 is stabilized due to the strengthening health awareness of the world population, steady demand for masks is expected to continue.

Despite such demand for masks, improvements in mask production facilities are insignificant. For more than 20 years, there has been no active improvement work on mask production facilities. However, due to the worldwide epidemic of COVID-19 in 2020, the era of attention to the excellent quarantine function of masks has arrived, and the demand for equipment to produce masks has also exploded. However, as a result of hastily introducing and using designs for mask production facilities that had been neglected from improvement for a long time, many mask manufacturers had to spend additional operating manpower/cost on various operational issues, including responding to frequent breakdowns, resulting in profitability. I have experienced this exacerbating problem. However, considering, for example, consumer awareness of masks and mask sales prices caused by COVID-19, demand for mask production is still expected to continue, which reduces operational losses for mask production facilities. that is required

Although COVID-19 is currently entering a gradual calming phase thanks to the efforts of each country, there is a possibility that deciduous blight will be prevalent again in the future, so it will be necessary to prepare for it, and considering the response to yellow dust or fine dust, demand for mask production will continue is expected to remain constant. Accordingly, the opinion that emergency mask production facilities at the national or local government level should be maintained even in preparation for a shortage of masks in the event of a re-epidemic of the epidemic is also gaining strength.

Equipment for mask production can be generally divided into a mask body molding device for forming a mask body and a device for bonding ear straps to the produced mask body. In general, considering the fact that the processing speed of the ear strap bonding device is relatively low compared to the production speed of the mask body forming device that forms the mask body based on fabric and filters wound in a roll form, a single mask body forming device and a plurality of ear straps A mask production facility that includes a combination of bonding devices has been mainly utilized. However, in order to expand the production facility to meet the ever-increasing demand for masks, this type of combination includes a plurality of combinations, making it difficult to design the layout of the entire production facility, space utilization is low, and management supervision is required. There is also a problem that requires considerable human resources for this.

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 (eg, 400 sheets/min or more) machines, but the front and back processes do not keep up with the mask production speed. There are many cases in which it was useless. In addition, in the case of high-speed production machines, there are many restrictions on operating at a slower production speed until COVID-19 is suppressed and other infectious diseases are prevalent again.

In relation to this, FIG. 1 is an exemplary view of a mask mass production facility according to the prior art. As shown in FIG. 1, a basic unit 100 of a mask production facility for mask production may include a mask body forming device 110 for manufacturing a mask body and a plurality of ear strap bonding devices 151 and 152. there is. Typically, since the working speed of the body molding 110 for forming the mask body using the fabric and the filter wound in a roll form is faster than the processing speed of the ear string bonding devices 151 and 152, a plurality of ear string bonding devices can be placed. However, the basic unit 100 of such a mask production facility also has a limited number of masks that can be produced within a given time. Therefore, for mass production of masks, a plurality of basic units 100 of such a mask production facility are provided. According to the layout 10 according to the prior art, as shown in FIG. 1, such a basic unit 100 ), in order to arrange a plurality of them, even if you try to increase the space utilization as much as possible, a waste of space inevitably occurs.

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/minute. In relation to this, if any one of the main body molding devices 110 has a malfunction, inspection, or material replacement, etc., the operation of the entire basic unit 100 is stopped, so that the ear strap bonding devices 151 and 152 also will stop working. Conversely, when a reason for stopping the operation of the ear strap bonding devices 151 and 152 occurs, the main body molding device 110 also stops working.

In addition to the limitation of production speed, the operation manpower for the mask production facility is also excessively required. Since the main body molding device 110 or the arrangement or position of the ear string bonding devices 151 and 152 are different from each other, the movement of operating personnel for inspection may be inefficient and require more manpower. Even if manpower with expertise in both the main body molding device 110 and the ear strap bonding devices 151 and 152 is put in order to reduce the number of manpower, it is inevitable that it takes a longer time 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 devices 110 or the ear strap bonding devices 151 and 152 are different and the complexity of the position difference is high. , it is impossible to automate the supply of raw materials such as fabrics, 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 facility is also impossible.

The multi-unit integrated mask production system according to an embodiment of the present invention is intended to solve this problem, and rearranges the conventional old and unreasonable modular production line to improve speed, operational convenience and flexibility, system automation and scalability, etc. It is a system that can see improvement effects in many ways, and at the same time, it can be an exemplary operation case of a smart factory.

In relation to this, FIG. 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 junctions It is possible to implement a multi-unit integrated mask production system 200 based on a multi-multi smart factory by organically coupling the ear loop junction 250 including the unit through the transfer unit 230. As shown in FIG. 2, it can be configured to have a rather higher production speed of 1000 sheets/minute or more within a much smaller installation space than, for example, 14 m × 14 m production equipment with a layout according to the prior art. there is.

For example, in the multi-unit integrated mask production system 200 as shown in FIG. 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, so that a total of 1000 sheets/min. It is possible to implement a mask production system of more than a minute. 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 it is possible to have an aligned distribution line. In addition, it is easy to additionally expand the main body molding device or bonding unit, and it is possible to drastically reduce the number of manpower specializing in machine device management. By minimizing the movement of workers, it is possible to operate with only about 1/3 of the operating personnel compared to the conventional one. In addition, as shown in FIG. 2, the material input positions for the main body molding devices or bonding units can be aligned, respectively, so that the supply of raw materials such as fabric, filters, or ear straps can be automated (Material Auto Feeding). there is. In addition, since the output position of the ear strap bonding device for the completed mask can also be aligned, automation of the mask packaging facility (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 such that the entire system does not stop even during periodic replacement of raw materials such as body fabric and ear straps. Also, the system does not stop even when some equipment is being serviced. For example, according to one aspect of the present invention, the operation of the entire system can be prevented from being stopped even when some equipment is shut down by separating the main process and the tail process and integrating the two systems organically (M2M). .

In addition, 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 by the body shaping device may be automatically distributed to a corresponding ear string splicer according to a programmed situation. In addition, according to one aspect, the speed of the main body molding device may be automatically controlled according to the processing speed of the ear string bonding unit. Furthermore, various types of masks, such as panel/3D, large/small, can be configured to be automatically dispensed by the conveying system to appropriate ear strap bonding units.

Here, according to one aspect of the present invention, a transformable ear loop bonding unit (Transformable Ear Loop Bonding System) (Auto changing) may be applied. For example, the ear strap bonding unit may be set to correspond to a panel type mask to a 3D (fish type) mask only by touch manipulation. In addition, it can be set so that fine changes in other detailed models can be joined according to the previously 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 flow of workers/raw materials/finished products can be arranged in a layout suitable for logistics. Therefore, it is possible to create room in the arrangement of workers based on the organized movement. In addition, it is possible to easily implement a connection with factory automation (Smart Factory) functions such as an automatic fabric replacement system and an automatic packaging system.

In addition, it can be configured to join even minute changes in detailed models according to pre-memorized dimensions.

For example, according to one aspect of the present invention, the main controller 270 provided in the multi-unit integrated mask production system according to an embodiment of the present invention may be implemented by a computing device including a processor and a memory. The memory may be configured to store data, and the processor may be configured to generate operations or instructions for controlling components. Also, for example, the main control unit 270 may have an input unit capable of allowing the user to perform mask body type setting for the bonding unit. The input unit may be, for example, a touch screen, and at least one of a button for selecting a specific bonding unit and a button for selecting a mask body type for the bonding unit may be displayed on the touch screen. However, note that the input unit according to the present invention is not limited thereto, and any means for enabling a user to set a mask body type for at least one bonding unit may be employed.

More specifically, according to one aspect of the present invention, in the memory of the main control unit 270, i) mask type information and ii) position information of ear loop junction points for the mask type of the mask type information, distance between ear loop junction points, Alternatively, a plurality of setting information each including information about at least one of the lengths of the ear string to be bonded may be stored. That is, the plurality of setting information is at least one of information on a plurality of mask body types, information related to a bonding position required for ear string bonding corresponding to the corresponding mask body type information, or information about the length of the ear string to be bonded. is included Even for the same type of mask, the length of the ear string to be joined may be different according to the preference of the consumer or manufacturer. In this case, the first sub-type and the second sub-type may be separated for the same mask body type so that different ear strap lengths for the corresponding sub-type are stored.

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

Therefore, the main controller 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 may be configured to set a mask type for at least one of That is, when the user simply selects a specific mask body type for a specific bonding unit through the input unit, the main control unit 270 determines the ear strap bonding position or interval so that the corresponding bonding unit can bond ear straps to the mask body of that type. , Or information on at least one of the lengths of the spliced ears may be obtained from setting information and applied to the splicing unit.

In relation to this, Fig. 8 is an information flow chart between the main control unit and the ear loop joint of the multi-unit integrated mask production system. As shown in FIG. 8 , the main controller 270 may receive a mask type setting instruction from the user through the input unit (step 810). The mask type setting instruction may include information on selection of a specific mask body type for a specific bonding unit. Then, the main controller 270 can select at least one of a plurality of pieces of setting information stored in the memory, for example (step 820). This may be to select setting information corresponding to the mask body type included in the mask type setting instruction. Subsequently, the main control unit 270 may transmit the mask type setting instruction to the ear loop bonding unit 250, more specifically to the specific bonding unit included in the mask type setting instruction (step 830). According to one aspect, the mask type setting instruction may include information on at least one of an ear string bonding position or interval according to setting information obtained by the main controller 270 or a length of an ear string to be bonded. The ear strap bonding unit 250 or a specific bonding unit may set the mask body type based on this (step 840) and change the setting to be suitable for the corresponding mask body. The ear loop bonding unit 250 or the 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 such a procedure, for example, after setting is completed to perform ear loop bonding on the first type of mask body with respect to the first bonding unit, the main control unit 270 transmits the first bonding unit from at least one body molding device. The transfer unit 230 can be controlled to transfer the mask body of one type to the first combination unit as above.

Meanwhile, with reference to FIG. 4 again, an exemplary first layout of a multi-unit integrated mask production system according to an embodiment of the present invention will be described in more detail.

On the other hand, in this specification, the 'length direction' of the mask body may mean a direction from one side to which ear strings can be bonded to the other side to which ear strings can be bonded based on the mask body. For example, assuming that a mask is worn on a human body, the 'longitudinal direction' of the mask body may mean a left-right direction. Also, 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 a human body, 'width direction' may mean a vertical 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 body may mean input or output by moving the mask body in the longitudinal direction. . Therefore, in the case of input or output in the 'length direction' of the mask body, the left end or right end of the mask body may be input or output while leading the mask body. Also, the mask body oriented in the 'longitudinal direction' may mean that the mask body is oriented to move in the longitudinal direction.

Conversely, inputting or outputting the mask body in the 'width direction' of the mask body may mean that the mask body is moved in the width direction and input or output. Therefore, when input or output is performed in the 'width direction' of the mask body, the upper or lower end of the mask body may be input or output while leading the mask body.
