Description

Sheet printed two dimensions-bar code and floor materials pieced on sheet}

The present invention relates to a sheet printed with a two-dimensional barcode and a flooring sheet adhered to the sheet. In particular, the barcode reader mounted on the autonomous mobile robot develops a colorless secret ink which is not visually identified, and scans the two-dimensional barcode to autonomously. It enables the mobile robot to recognize the current position quickly, and since the two-dimensional barcode is printed on the back of the seat, it can be used for a long time without fear of damage or damage to the two-dimensional barcode even by surface abrasion or damage by the autonomous mobile robot and the user. It relates to a sheet on which two-dimensional barcodes are printed and a sheet on which two-dimensional barcodes are printed and a flooring on which the sheets are bonded.

In general, in homes, officetels, and public offices, vinyl flooring, marble, tiles, and the like are installed on the floor to make a person's feet comfortable or beautiful.

In addition, autonomous mobile robots, which are essentially unmanned operation, are emerging as a topic in modern home automation. Currently, autonomous mobile robots are moving in order to perform autonomous mobile robots in a moving space or area. Or, the most important part is to correctly recognize the absolute position information where the autonomous mobile robot to start moving is located.

Therefore, in the related art, in order for the autonomous mobile robot to recognize the absolute position in the moving area, the absolute coordinate information is installed on the bottom surface so that the autonomous mobile robot acquires the absolute coordinate, thereby calculating the relative coordinates from the absolute coordinates and the direction of movement, The distance can be calculated quickly and accurately.

Here, the conventional method of installing the absolute coordinate information on the bottom surface is a method of embedding the RFID card 1 on the bottom surface 2, this method is a bottom surface having a double structure (as shown in FIG. It has a structure for embedding the RFID card 1 in 2), the structure is complicated and the embedding work is very troublesome.

In addition, in the position and direction recognition method using the RFID, the accuracy of position and direction recognition of the autonomous mobile robot 3 is determined according to the distribution density of the RFID card 1. If the distribution density of the RFID card 1 is too low, the precise position and direction recognition of the autonomous mobile robot 3 cannot be expected. If the distribution density of the RFID card 1 is too high, the RFID card ( An error may occur in reading the unique number due to mutual interference between RF signals output from 1a) (1b) and 1c.

Therefore, in order to prevent an error from occurring, the embedding distribution density of the RFID card 1 must be limited to an appropriate range, which causes a decrease in the accuracy of the position and orientation recognition method using the RFID. In addition, an error may occur when there is an object absorbing a magnetic field in a place where the RFID cards 1 are embedded.

In addition, in the RFID method described above, in order to recognize a direction, the RFID card reader 4 must simultaneously recognize at least two RFID cards 1a, 1b, and 1c. If the density is not high enough, it becomes difficult to recognize the direction.

In particular, the RFID method is inconvenient to embed the RFID card (1) on the bottom surface 2, if the RFID card (1) is damaged, repair the entire floor or extract only the RFID card (1) In addition, since the RFID card 1 needs to be embedded again, there is a problem in that the appearance is not good.

In addition, when the RFID card 1 is used in a large area, a plurality of RFID cards 1 must be used, so that an expensive installation cost is required in operating the autonomous mobile robot 3 as well as during maintenance. In addition, it is necessary to pay attention to damage, and expensive maintenance costs are caused.

Accordingly, in order to solve the above problem, the applicant filed a 3D bar code printed plate (Application No. 20-2004-0008728) on March 30, 2004, but the direct printing of the 2D bar code on the surface of the flat plate The method can be applied and adopted to flooring materials such as floor coverings and tiles that are newly manufactured, but it is difficult and inconvenient to print and print on flooring materials such as floor coverings and tiles or wooden floors, which are already manufactured. There is a need for a separate means.

The present invention devised by solving the above problems and demands does not directly print two-dimensional barcodes printed for securing absolute coordinates of autonomous mobile robots on flooring materials such as flooring sheets or tiles, and has two-dimensional barcodes having different information on transparent sheets. After printing, this sheet can be attached to the flooring material so that it can be used for pre-made products, and in order to make maintenance easier by replacing easily in case of damage in use. have.

The above object is to reverse-print the two-dimensional bar code 102 having different predetermined position information on the back surface of the transparent sheet 101 having a predetermined area so that it can be placed in the right position when viewed from the surface, and the adhesive on the back surface. The two-dimensional bar code 102, which is characterized in that the coated adhesive layer 103 is formed, is achieved by a printed sheet.

Here, the two-dimensional bar code 102 is preferably printed with any one of the color ink 102a that can be visually identified and the colorless secret ink 102b that is not visually identified.

On the other hand, the above object is to reverse-print the two-dimensional bar code 102 having different predetermined position information on the back surface of the sheet 101 of the transparent material having a predetermined area so as to be placed in the correct position when viewed from the surface, It is also achieved by a flooring material characterized in that at least one or more sheets 101 on which the adhesive layer 103 is formed are adhered to the surface.

Here, the two-dimensional bar code 102 is preferably printed with any one of the color ink 102a that can be visually identified and the colorless secret ink 102b that is not visually identified.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings, FIGS. 2 to 4.

First, according to the first embodiment of the present invention, as shown in FIGS. 2 and 3, a plurality of two-dimensional barcodes 102a with colored ink on one side (back side or back side) of a film or sheet 101 having a transparent material. Print

Here, the two-dimensional bar code 102a is set in a conventional bar code printer (not shown) to have different position information.

For example, when the two-dimensional barcode 102 is printed at a distance of 30 cm up, down, left, and right, six two-dimensional barcodes 102 are printed in the horizontal direction if the length and width of the film paper or the sheet 101 are 180 cm × 180 cm. Six two-dimensional barcodes 102 may be printed in the longitudinal direction, and each of these two-dimensional barcodes 102 may have (0,1) (0,1), (0,2), (0,3). ), (0,4), (0,5), (1,1) (1,1) ... (1,5) ... (5,4), (5,5) It is possible to have information, which applies equally to the two-dimensional bar code 102 printed in the second embodiment.

In this case, the information of the two-dimensional bar code 102 is unique position information, so that the plurality of two-dimensional bar codes 102 have different position information.

Therefore, the autonomous mobile robot 105 moving above the two-dimensional bar code 102 scans the two-dimensional bar code 102 each time the two-dimensional bar code 102 passes, and acquires unique position information, and obtains the obtained position information. With reference to the current position in the moving area, the path, direction, speed, etc. to be moved forward can be set and maintained.

In addition, the two-dimensional barcode 102a printed on the film or sheet 101 has a printed surface on the back or the back surface as shown in FIGS. 2 and 3, and the two-dimensional barcode 102a is placed on the front surface or the front surface. The two-dimensional barcode 102a can be protected from frictional force or damage applied to the surface because it is reverse printed so that it can be expressed and identified.

3A and 3B, the adhesive layer 103 is formed by applying an adhesive to the printing surface, that is, the back surface of the two-dimensional barcode 102a manufactured as described above. 104 may be adhered to, and in some cases, an adhesive layer 103 protective film (not shown) is attached to the adhesive surface of these sheets 101 to remove the protective film when the sheet 101 is used, and then the sheet 101 is plated. It may be attached to the flooring material 104, such as flooring or the like is preferred, but the present invention is not limited thereto.

Meanwhile, when the sheet 101 is attached to a predetermined area of the flooring 104 such as a floor covering or a floor, the two-dimensional bar code 102a printed on the plurality of sheets 101 may have different position information. The absolute coordinate value of the two-dimensional barcode 102a is read out by the barcode reader 106.

The sheet 101 as described above may be used to enable the autonomous mobile robot 105 to obtain the absolute coordinate value in the flooring 104, such as floor coverings, tiles, floors, and the like.

On the other hand, when manufacturing the flooring material 104, such as the flooring sheet is printed by printing a pattern on the surface of the predetermined length by cutting the unit rolls, at this time, by attaching the sheet 101 to the surface of the floorboard to be rolled, As shown in FIG. 4, the flooring 104 can be installed in a state in which an absolute coordinate value obtained by the autonomous mobile robot 105 can be obtained, and a separate operation for attaching the seat 101 is excluded. And it is desirable to be able to shorten the working time required for the installation of the flooring 104.

The second embodiment of the present invention has the same structure as the sheet 101 of the first embodiment, except that the two-dimensional bar code 102b printed on the sheet 101 is a transparent ink or a secret ink which is not visually identified. Occurs.

That is, as shown in FIG. 3B, ink which is not visually identified is currently used as colorless and is colorless, even if printed on securities or security paper such as banknotes, checks, gift certificates, etc. This is not visible and scanning and copying are not performed by scanning, copying, or the like.

The secret ink may be an organic fluorescent material, a quencher, and a curable resin composition that emit light in the wavelength region of 651 nm to 900 nm by a light emitting element that emits a wavelength of 550 nm to 850 nm. EC (EC: 2-ethoxyethanol (2 -ETHOXYETHANOL; Molecular formula: C4H10O2)), 40% to 20% of MT (methyl alcohol) is mixed to prepare 1L of solution A, and to the solution A, puenonor futadan and fusiral resin or CKR resin (Mgo-reactive Alkyl Phenol). Resin) 10g to 20g and 130g to 170g, and 15cc to 25cc of OX (orenoic acid: C17H23CO2H) heated to 180 ℃ ~ 220 ℃ and may be made by mixing 0.01g ~ 0.001g Si The present invention is not limited to this, but the transparent ink or the secret ink should be visually identified by the light emitting device irradiating light in the wavelength range of 550 nm to 850 nm.

The ink is not usually visually identified and can be obtained by irradiating light only when the absolute coordinate value is obtained by the autonomous mobile robot 105, thereby maintaining the appearance of the beautiful flooring material 104.

Therefore, as in the first embodiment, the two-dimensional barcode 102b is inversely printed with a transparent ink on the back surface of the film or sheet 101 so that the light emitting element 107 irradiates light from the surface to the two-dimensional barcode. When the color 102b is developed, the two-dimensional barcode 102b reads information by the barcode reader 106 so that an absolute coordinate value can be obtained, and by applying an adhesive to the printing surface to form an adhesive layer 103, Even if the sheet 101 is attached to the surface of the flooring 104, such as a floor covering, tiles, floors, etc., the two-dimensional bar code 102b cannot be recognized by a person, and thus, the autonomous mobile robot 105 maintains the beauty of the floor surface. Can be used.

The two-dimensional bar code 102 shown in FIG. 4 is a virtual illustration of the two-dimensional bar code 102b which is not visually identified. The floor plate 104 is provided with a floor covering 104 installed in a rolling state, that is, the flooring 104. Attaching the sheet 101 to all is shown.

In addition, as in the first embodiment, the sheet 101 having the two-dimensional barcode 102b printed thereon is adhered to the flooring 104 so that the flooring 104 having the two-dimensional barcode 102b is commercially available as a sleeve. It is desirable to make it possible to achieve a convenient installation.

That is, according to the present invention, the two-dimensional bar code 102a on the back surface of the sheet 101 may be printed with colored ink, and may be printed by ink which is difficult to visually identify and distinguishable by light irradiation.

In addition, the sheet 101 may be attached to a flooring material 104 such as a floor covering or a floor installed in the past, or may be attached in the process of manufacturing the flooring material 104.

As described above, the present invention eliminates the hassle and inconvenience of embedding an RFID card on the floor surface or changing the structure of the flooring to a structure in which the RFID card can be buried in order to utilize the autonomous mobile robot. Without the use of expensive RFID cards, the two-dimensional barcode-printed sheets can be attached to flooring materials such as floor coverings, floors, tiles, etc. to utilize autonomous mobile robots. The autonomous mobile robot can be utilized to greatly contribute to the popularization of the autonomous mobile robot, and it is easy to assign two-dimensional barcodes to existing flooring materials or newly manufactured floorings, and to prevent the two-dimensional barcodes from being visually identified. It can also help to maintain the beautiful appearance of the flooring. The.
