Description

Earband printing device for mask {Printer for mask earband}

The present invention relates to a printing device for an ear band for a mask, and more specifically, to a printing device for an ear band for a mask that can simultaneously print both sides of the ear band.

As the wearing of masks becomes more common, the importance of the wearing comfort of the mask in addition to the filtering performance of the mask is emerging. Since typical masks are worn over the ears and on the face, if worn for a long time, the ear bands may press on the ears and cause pain. Because of this, in order to improve the wearing comfort of the mask, the material and shape of the ear band became important factors in selecting the mask.

In the case of a typical mask, the ear bands have a circular cross-section and are manufactured by woven, braided, or drawn and injected from elastic natural or synthetic resin yarns.

In the case of ear bands with a circular cross-section, they are simple to manufacture and have a low unit price, which is advantageous in terms of cost reduction due to mask manufacturing. However, if worn for a long time, they have the problem of compressing the skin, blocking blood flow, or easily causing pain. there was.

Accordingly, flat ear bands are sometimes used in masks to solve the above problems by increasing the contact area with the skin.

In the case of these flat ear bands, since they have a larger area compared to ear bands with a circular cross-section, design elements are added by printing a specific pattern on the surface, or a company's trademark is printed to use the mask as a promotional material.

When wearing a mask, the earband is worn without any particular direction, so the earband is easily turned over and worn. Therefore, the printed surface formed on the earband must be formed on both sides of the earband to be effective. Usually, the earband is used as an earband. It was common to print on both sides.

However, in order to print both sides, it was necessary to first print one side of the ear band raw material formed long in the longitudinal direction, then retrieve the ear band with one side printed, turn it over, and print the other side again. Since the printing process for both sides was performed separately, there was a problem of very low productivity and workability.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that identical members in each drawing may be indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

The mask ear band (1) printing device (hereinafter referred to as the printing device) according to the present invention can print a certain pattern on both sides before dividing the mask ear band (1) into equal parts in the length direction in order to couple it to the mask body. there is. At this time, pattern can be understood as a concept that includes specific phrases, trademarks, images, etc. For convenience of explanation, one side of the ear band 1 will be referred to as the flat surface 1a, and the surface opposite to the flat surface 1a will be referred to as the back surface 1b.

The printing device according to the present invention largely includes a table 10, a supply unit 20 for supplying the ear band 1 to the table 10, and an ear installed on the table 10 and supplied to the table 10. A flat printing unit 30 is installed on the table 10 and prints on the flat surface 1a of the band 1, and prints on the back surface 1b of the ear band 1 supplied to the table 10. The back side printing unit 40 and the flat surface printing unit 30 are installed between the back printing unit 40 and the ear band 1 passing through the flat printing unit 30 is twisted to form the flat surface 1a and the back surface (1a). 1b) may be defined as including an inversion unit 50 that inverts the positions of each other.

First, the supply unit 20 includes a storage roll 21 on which the ear band 1 before the pattern is printed is wound, and the ear band 1 unwound from the storage roll 21 is stretched across the table 10. It can be continuously pulled by the rewinding unit 60 installed at the rear end of the table 10.

At this time, the ear band 1 may be supplied to the table 10 in a state in which it is set to extend for a certain length in front of the table 10.

The ear band 1 is usually made of an elastic material, and when tension is applied to the ear band 1 between the supply unit 20 and the rewinding unit 60 due to the traction force of the rewinding unit 60, the ear band 1 Since the pattern is printed while the surface of the band 1 is stretched, there may be limitations in implementing an accurate pattern. Accordingly, a certain length margin is provided before the ear band 1 is supplied to the table 10, so that the ear band 1 is not easily stretched even when the rewinding unit 60 applies traction to the ear band 1. Equipped with

The rewinding unit 60 is installed at the rear end of the table 10 to continuously pull the ear band 1 supplied from the supply unit 20 toward the rear end of the table 10. The ear band 1 towed by can be recovered into the storage box 70 provided at the bottom of the rewinding unit 60.

Next, the table 10 is a plate-shaped structure that supports the flat printing unit 30, the back printing unit 40, the inversion unit 50, and the rewinding unit 60, and has an ear band (1) on the upper surface. ) may be formed with guide blocks 11 and 12 that guide the forward and backward directions. At this time, guide grooves 11a and 12a through which the ear band 1 passes may be formed in the guide blocks 11 and 12 to be long and recessed in the front-back direction.

The guide block can be divided into a first guide block (11) and a second guide block (12) spaced a certain distance apart in the front and rear directions, and a semi-circular block is formed between the first guide block (11) and the second guide block (12). All 50 can be arranged.

That is, the ear band 1 is first guided by the first guide block 11, and then in the section between the first guide block 11 and the second guide block 12, the guide groove of the first guide block 11 ( After exiting from 11a), it passes through the inversion part 50 and then is guided back into the guide groove 12a of the second guide block 12.

The flat surface printing unit 30 and the back printing unit 40 have the same configuration and follow a known structure in that a pattern can be printed on the flat surface 1a and the back surface 1b of the ear band 1, respectively. Detailed explanation is omitted.

However, in the case of the flat printing unit 30, it is installed directly above the first guide block 11 and can print a pattern on the flat surface 1a of the ear band 1 being guided by the first guide block 11. In the case of the back side printing unit 40, it is installed directly above the second guide block 12 and can print a pattern on the back side 1b of the ear band 1 being guided by the second guide block 12. there is. At this time, in the first guide block 11, the plane 1a of the ear band 1 is guided to face the top, and in the second guide block 12, the back surface 1b of the ear band 1 is guided to face the top. By being guided to view, the flat surface 1a and the back surface 1b of the ear band 1 are placed in the printing areas of the flat printing part 30 and the back printing part 40, respectively.

Meanwhile, the ear band 1 that has passed through the first guide block 11 is in a state where the plane 1a is facing upward, and is connected by the inversion portion 50 disposed at the rear of the first guide block 11. The band 1 is switched to an inverted state with the flat surface 1a facing downward and the back surface 1b facing upward and is supplied to the second guide block 12, so that the back surface 1b is facing upward.

That is, the inversion unit 50 twists the ear band 1 at least once between the first guide block 11 and the second guide block 12 to align the flat surface 1a and the back surface 1b of the ear band 1. They can be reversed. However, in some cases, when it is desired to form a pattern only on at least one of the plane 1a and the back surface 1b of the earband 1, the earband 1 may be configured not to be particularly twisted.

To this end, the inversion unit 50 may be illustrated as largely including a disk member 100 and a carrier 200 as shown in FIGS. 4 to 8 .

First, the disk member 100 is made in the shape of a disk and has a structure in which a slit 110 through which the ear band 1 passes is formed in the center. At this time, a plurality of disk members 100 may be provided and may be placed on the carrier 200 while being aligned in the front-back direction.

Each slit 110 has a structure that communicates with each other, and the ear band 1 can continuously pass through the communicated slits 110.

At this time, if the user arbitrarily rotates each disc member 100 at a certain angle, the path of the ear band 1 passing through the slit 110 is twisted due to the rotation of the disc member 100.

That is, as shown in FIG. 9A, when the slits 110 of each of the plurality of disk members 100 are aligned parallel to each other, no rotational resistance is applied to the ear band 1 passing through the inside of the slit 110. As a result, the ear band 1 passes through the inversion portion 50 in a straight unfolded state, so that the plane 1a and the back surface 1b of the ear band 1 are not inverted, as shown in Figure 9b. Likewise, when the user arbitrarily rotates a specific disk member 100 at a certain angle, but gradually increases the amount of rotation toward the rear within an angle range of 180 degrees, and manipulates the plurality of disk members 100, each slit 110 ) forms a rotation path and twists the ear band (1).

In this embodiment, the ear band 1 is gradually twisted using at least seven disk members 100. If the ear band 1 is not twisted gradually but is twisted radically at a specific part, the ear band 1 may be twisted gradually. As the frictional resistance with the ear band 1 increases within the slit 110, problems such as damage to the pattern that has not been completely dried on the surface of the ear band 1 or wrinkles in the ear band 1 occur.

On the other hand, when a plurality of disk members 100 are arranged adjacent to each other, it is difficult to check the rotation amount of the internal slit 110 from the outside. In this case, a plurality of disk members 100 are provided so that the user can easily determine the rotation amount of the disk member 100 with the naked eye. A marker 120 may be formed on the outer peripheral surface of each disk member 100.

That is, the user can determine the relative rotation amount of the disk member 100 based on the marker 120 formed on the outer peripheral surface of the disk member 100.

For example, as shown in FIG. 9A, when the markers 120 of each of the plurality of disk members 100 are aligned to be connected in line, the slits 110 of each of the plurality of disk members 100 are aligned parallel to each other to form an ear band. (1) has a structure that can pass without twisting, or, as shown in FIG. 9B, when the markers 120 of each of the plurality of disk members 100 are aligned to be connected in line, the plurality of disk members 100 ) Each slit 110 is provided with an alternative structure in which each slit 110 is aligned in a rotated state at a certain angle to twist the ear band 1, so that the user uses the marker 120 when rotating the disk member 100. Please make it available for reference.

On the other hand, when the ear band 1 is twisted inside the slit 110, it may become stuck between adjacent disk members 100 or leave marks on the ear band 1 due to the front and rear end corners of the slit 110. As shown in FIG. 10, the penetration area of the slit 110 may be gradually expanded in the front-back direction.

Accordingly, even if the ear band 1 is twisted, the front and rear end corners of the slit 110 can be opened to a sufficient area, so that the ear band 1 is not wrinkled or has marks caused by being pressed against the corners.

Additionally, in order to allow the earband 1 to pass more smoothly inside the slit 110, a roller 140 may be installed on the inner wall facing the slit 110 so that it can rotate in place.

That is, when the ear band 1 passes through the slit 110, the roller 140 comes into rolling contact with the ear band 1, and thus the ear band 1 quickly passes through the slit 110 without frictional resistance. There is a structure in place to pass through.

At this time, a Teflon layer may be coated on the outer peripheral surface of the roller 140. Since Teflon has a low coefficient of friction, the flat surface 1a or the back surface 1b of the ear band 1 has a structure in which less-dried ink does not easily adhere to the surface of the roller 140. Therefore, even if the ink is not completely dried, color transfer due to the roller 140 coming into contact with the ear band 1 can be prevented.

Next, the carrier 200 is configured to rotatably support a plurality of disk members 100 in a row, and the plurality of disk members 100 are placed simultaneously while seated and coupled to the upper surface of the table 10.

Each disk member 100 placed on the carrier 200 can be rotated in place, and in some cases, some of the disk members 100 placed on the carrier 200 can be removed or added.

More specifically, the carrier 200 may be illustrated as largely including a support plate 210 and an upper frame 220 as shown in FIG. 5 .

First, the support plate 210 is formed in the form of a semi-cylinder with an empty interior, and on the inner peripheral surface, a plurality of support grooves 211 are formed to be recessed at equal intervals in the front and rear direction so that each of the plurality of disk members 100 is inserted and fixed, thereby forming a plurality of disk members 100. (100) is supported and spaced apart.

Each disk member 100 inserted and fixed into each support groove 211 is configured to be rotated in place while being spaced a certain distance apart from each other and restricted from moving forward and backward.

That is, the user can arbitrarily rotate each disk member 100 mounted on the support plate 210.

Meanwhile, each disc member 100 is prevented from being rotated arbitrarily unless the user arbitrarily rotates it on the support plate 210, so that the state rotated at a certain angle is properly maintained, thereby stably twisting the ear band 1. In addition, in the case of Depending on this, when the user applies torque to rotate it arbitrarily, the amount of rotation of the disk member 100 can be easily adjusted by allowing it to rotate appropriately.

For this purpose, as shown in FIG. 8, an installation hole 212 is recessed in each of the plurality of support grooves 211, and the installation hole 212 is provided with a locking piece that is elastically pressed upward by an elastic spring 213. 214) is installed, and a plurality of locking protrusions 130 are continuously formed on the outer peripheral surface of the plurality of disk members 100 and have a structure in which they are hooked and supported by the locking piece 214.

At this time, the locking protrusion 130 is formed to protrude in a continuous triangular shape along the circumferential direction of the outer peripheral surface of the disk member 100, and the end of the locking piece 214 has a complementary triangular shape between the adjacent locking protrusions 130.

The installation port 212 may be recessed to a certain depth from the bottom of the support groove 211 toward the bottom, and an elastic spring 213 and a locking piece 214 may be installed in the installation port 212.

The upper end of the locking piece 214 has a structure that protrudes to a certain extent upward from the top of the installation hole 212 and is caught by the locking protrusion 130 formed on the outer peripheral surface of the disk member 100 seated and fixed in the support groove 211. It can be supported by being caught between the jaws (130).

When the locking piece 214 is located between adjacent locking steps 130, the elastic pressing force of the elastic spring 213 acts so that the locking piece 214 is grounded between the adjacent locking steps 130, and thus the disk member ( 100) has a structure in which the rotation is restricted.

However, when the user applies arbitrary torque to the disk member 100 in order to twist the ear band 1 passing through the slit 110, the locking piece 214 moves along the slope of the adjacent locking ledge 130. As it exits between 130, the disk member 100 rotates. Meanwhile, when the fixing position of the disk member 100 is determined, the locking piece 214 is grounded between the locking protrusions 130, so that the disk member 100 can be fixed without rotating arbitrarily.

Next, the upper frame 220 is formed on the upper part of the supporting plate 210 and covers the upper part of the disk member 100 supported on the supporting plate 210.

That is, the upper frame 220 can restrict the upward movement of the disk member 100 mounted on the support plate 210, and in some cases, the disk member 100 can be replaced by opening the upper part of the support plate 210. It can be configured. A disk member 100 having slits 110 of different sizes may be provided depending on the thickness of the ear band 1, etc., and the user may provide a slit 110 of an appropriate size through which the ear band 1 to be printed can pass. ) It is possible to set up the printing device by replacing the original plate member 100 having a.

The upper frame 220 is rotatably coupled to the front and rear of the support plate 210 via, for example, a hinge 222, and includes a pair of arch frame members 221 and the pair of arch frame members. It may be illustrated as including a bar-shaped connecting frame member 223 supported on the upper part of a plurality of disk members 100 interconnected to the upper end of 221 and supported on the support plate 210.

Accordingly, a structure is formed in which a certain section is formed open between the connecting frame member 223 and the support plate 210, and a portion of the outer peripheral surface of the disk member 100 supported on the support plate 210 can be exposed through the open portion.

Therefore, even when the disk member 100 is supported on the carrier 200, the disk member 100 can be rotated to the open portion, thereby ensuring convenience of operation.

Meanwhile, magnifying glasses (13, 14) are combined with the first guide block (11) and the second guide block (12) to visually check whether the pattern is correctly printed on the ear band (1) running in the guide grooves (11a, 12a). You can zoom in and check, so you can check printing defects in advance before they are returned to the storage box (70).

Hereinafter, the process of printing a pattern on the ear band 1 will be described with reference to the attached drawings.

First, in order to connect and install the ear band 1 to the printing device, the user connects the ear band 1 unwound from the supply unit 20 to the first guide block 11, the inversion unit 50, and the second guide block 12. ) and connected to the rewinding unit (60).

At this time, when connecting the ear band 1 to the inversion portion 50, as shown in FIG. 9A, the slits 110 of each disk member 100 are set to be aligned parallel to each other, and the slits communicate with each other. Insert the ear band (1) between the (110) and pass the inversion portion (50), and when the ear band (1) completely penetrates each slit (110), the user guides each disk member (100). As shown in 9b, the path of the ear band 1 passing through the slit 110 is twisted by appropriately rotating and aligning.

Accordingly, the ear band 1 guided by the first guide block 11 is arranged with the plane 1a facing upward, and the ear band 1 guided by the second guide block 12 is arranged with the back surface 1b. It can be arranged to face the upper part, and at this time, the flat printing part 30 and the back printing part 40 are aligned with the guide grooves 11a and 12a of the first guide block 11 and the second guide block 12, respectively. Pattern printing is performed on the ear band (1) passing through.

Meanwhile, in some cases, as shown in FIG. 11, when the ear band 1 is twisted by the inversion part 50, a tensile force is applied to prevent the ear band 1 from being excessively stretched. Synchronous rollers (R1, R2) may be installed at the front and rear to rotate synchronously.

At this time, the ear band 1 may be installed to be wound around each of the synchronous rollers R1 and R2 at least one turn, and accordingly, even if a tensile force is applied when the ear band 1 is twisted in the inversion portion 50. It can be configured so that no tensile force is applied to the portion beyond the pair of synchronous rollers (R1, R2), for example, in the direction toward the flat printing unit 30 and the back printing unit 40. Each synchronous roller (R1, R2) can be operated to rotate synchronously in place by the synchronous motors (M1, M2).

Therefore, in order to print both sides of the ear band (1), the flat surface (1a) of the ear band (1) is first printed, and then the ear band (1) is turned over again and put into the printing device to print the back side (1b). As shown in FIG. 12, it is possible to form a printed surface on both sides of the ear band 1 with a single input of the printing device without the need to perform a process, thereby significantly improving productivity and work convenience.
