Description

Technical Field

[0001] The present invention relates to an inkjet device and an inkjet method.

Background Art

[0002] In the inkjet work on the floor surface (for example, a concrete surface) at a construction site, multiple workers perform surveying, and while referring to the design drawing, they perform inkjet at the grid point positions of the center lines on the floor surface. Two workers fix both ends of the ink pot string at two grid point positions and stretch it. After pulling the ink pot string upward and then releasing it, the center line is inkjet. Inkjet of a large number of center lines that are orthogonal to each other on the floor surface is performed, and runners along which columns (intermediate columns) such as studs are to be erected are attached to the floor surface along each center line. For example, runners are attached to the floor surface along the center lines in the X direction (X1 center line, X2 center line, ···) and the center lines in the Y direction (Y1 center line, Y2 center line, ···) that are orthogonal to each other. In addition, this inkjet work includes not only the inkjet for building walls and columns but also the inkjet for setting the installation positions of various facilities installed inside the building.

[0003] In the above inkjet work, workers perform surveying and reading of the design drawing. However, surveying requires a certain amount of experience, and reading of the design drawing also requires knowledge and experience. Therefore, surveying errors and reading errors of the design drawing become problems. In addition, building materials such as runners attached along each center line may have different sizes for each location. Therefore, it is necessary to appropriately display the size of the building material according to the center line on the floor surface, which is a time-consuming task. Also, since it is an inkjet based on the surveying by workers and reading of the design drawing, it takes a considerable amount of time to perform inkjet over the entire floor surface.

[0004] Here, Patent Document 1 relates to a method of marking a concrete surface for positioning. After assembling the formwork, prior to placing the concrete, on the concrete placement surface of the assembled formwork, using a coloring paint that can be transferred to the surface of the hardened concrete, markings for positioning such as boundary lines and attachment positions are drawn. After the placed concrete has hardened and the formwork is removed, the drawn positioning markings are transferred to the surface of the in-situ cast concrete structure to perform marking for positioning on the concrete surface. A method of marking the concrete surface has been proposed.

[0005] On the other hand, Patent Document 2 relates to a method of marking a reference level during the construction of a building. During formwork construction, a magnet is attached to the steel bars to align its center position with the reference level. During concrete placement, the magnet is embedded in the concrete as it is. During finishing work, the center position of the magnet is detected from the concrete surface, and using the detected position as the reference level, a marking method for marking on the concrete surface is proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0007] Both of the marking methods described in Patent Documents 1 and 2 have a common characteristic configuration that eliminates the marking of the reference position by the worker. However, instead of being a marking method by the worker, problems related to surveying errors and reading errors of the design drawings, and problems such as the time required for marking the entire floor area are still included.

[0008] The present invention has been made in view of the above problems, and an object thereof is to provide a marking device and a marking method that can eliminate surveying errors and reading errors in design drawings and can shorten the time required for marking.

Means for Solving the Problems

[0009] To achieve the above object, one aspect of the marking device according to the present invention is a marking device that self-runs on a marking surface to perform marking, incorporates a control device, and the control device includes a traveling unit, a position specifying unit that specifies its own position information, a reading unit that reads marking source drawing data, and a drawing unit that performs marking, The drawing unit is characterized by drawing grid markings corresponding to the intersection form at the grid positions where a plurality of members intersect based on the drawing rule information.

[0010] According to this aspect, the marking device reads the marking source drawing data by the reading unit, the position specifying unit specifies the position of the device itself, moves to the position to be drawn by the traveling unit, and performs marking by the drawing unit at a predetermined position on the floor surface. Thus, marking on the floor surface can be performed only by the marking device, eliminating surveying errors and reading errors in design drawings by the operator and shortening the time required for marking. Here, the drawing method by the drawing unit is to draw grid markings corresponding to the intersection form at the grid positions where a plurality of members intersect based on the set drawing rule information. Therefore, the marking device that has read the marking source drawing data by the reading unit sequentially moves to the grid positions such as the center lines that intersect each other, and draws grid markings corresponding to the intersection form at each grid position.

[0011] The "intersection form" described above can be exemplified by a form in which two members (e.g., runners) that intersect each other are orthogonal, a form in which three members (or two members) that intersect each other intersect in a T shape, and the like. Further, the "drawing rule information" means information in which the type of drawing (drawing stamp) is set for each intersection form of a plurality of members at the grid point position. For example, in the intersection form in which two members are orthogonal to each other, the drawing stamp set corresponding to the orthogonal form is drawn at the grid point position.

[0012] Identifying the position information of the device itself (corresponding to surveying) and reading the original drawing data for inking are tasks that the device is good at compared to the operator and can be executed without error. Therefore, by having at least the inking device execute the drawing of the grid markings for each grid point position based on these tasks, high-precision inking can be performed in as short a time as possible.

[0013] Here, if the inking device executes the drawing of the grid markings for each grid point position and, for example, two operators perform the inking of the connection line markings that connect the grid markings to each other, the inking of the connection line markings can be executed all at once simply by pulling the inking string upward and then releasing it. Therefore, by separating the inking work content that the inking device is good at and the inking work content that the operator is good at (the operator is more efficient than the inking device), it is possible to realize an inking operation without errors while shortening the time required for inking.

[0014] Another aspect of the inking device according to the present invention is In the process of self-running by the traveling unit, the drawing unit is characterized by drawing connection line markings that connect a plurality of the grid markings according to the intersection form.

[0015] According to this aspect, in addition to drawing the grid markings for each grid point position, the inking device draws connection line markings that connect the grid markings to each other while self-running, so that the inking device executes all the inking on the floor surface, and the inking work by the operator can be eliminated.

[0016] In another aspect of the inkjet device according to the present invention, the grid marking includes a grid stamp including the sizes of the members intersecting with each other, and an intersection pattern stamp corresponding to an intersection pattern in which two or more of the members intersect at the grid positions, which is characterized in that.

[0017] According to this aspect, since the grid marking includes a grid stamp including the sizes of the members intersecting with each other and an intersection pattern stamp corresponding to an intersection pattern in which two or more members intersect at the grid positions, when building members along the inkjet, it is possible to eliminate construction mistakes in which workers install members of sizes different from the design, and further, it is possible to eliminate construction mistakes in which workers install members in an intersection pattern different from the design.

[0018] In another aspect of the inkjet device according to the present invention, the position specifying unit includes a target of a measuring instrument and a receiver that receives its own position data transmitted from the measuring instrument, which is characterized in that.

[0019] According to this aspect, for example, light waves are irradiated from a measuring instrument provided at a reference position to a target (such as a prism) provided in the inkjet device, and the measuring instrument measures the light waves reflected by the target, thereby obtaining the distance, vertical angle, and horizontal angle between the target, and specifying the three-dimensional position of the target (inkjet device). By the receiver receiving this three-dimensional position data, the inkjet device can specify its own three-dimensional position information (position information on the floor surface). Note that the inkjet device may be provided with, for example, GPS (Global Positioning System), but unlike moving means outdoors such as vehicles, when trying to obtain three-dimensional position information by GPS on the floor surface below where the ceiling such as a roof has already been constructed, it is often difficult to obtain sufficient position information. Therefore, it is desirable to apply a measuring instrument installed at the reference position of the floor surface to be inkjet as in this aspect.

[0020] Also, one aspect of the inkjet method according to the present invention is A printing method in which a printing device is made to run automatically on a printing surface while performing printing, causing the printing device to read printing source drawing data, making the printing device run automatically while specifying its own position information based on the printing source drawing data, and drawing grid markings corresponding to the intersection form at grid positions where a plurality of members intersect based on drawing rule information.

[0021] According to this aspect, by using a printing device to read printing source drawing data, moving the device to the position to be drawn while the device specifies its own position, and performing printing at a predetermined position on the floor surface, printing on the floor surface can be performed only by the printing device, eliminating measurement errors and drawing reading errors by workers, and shortening the time required for printing. Also, by drawing grid markings corresponding to the intersection form at grid positions where a plurality of members intersect based on drawing rule information, efficient drawing of grid markings by the printing device can be realized, and workers who understand the drawing rule information can install members of the designed size in the designed intersection form based on the drawn grid markings.

[0022] Another aspect of the printing method according to the present invention is characterized in that two workers connect the grid markings drawn by the printing method by printing, or draw and connect connection line markings while making the printing device run automatically.

[0023] According to this aspect, the inking device executes the drawing of the grid markings for each grid point position, and for example, two workers perform the inking of the connecting line markings that connect the grid markings to each other. Since the inking of the connecting line markings can be executed all at once simply by pulling up the ink pot thread and then releasing it, by separating the inking work content that the inking device is good at from the inking work content that the worker is good at and executing them, it is possible to realize an inking operation without mistakes while shortening the time required for inking. On the other hand, when the inking device draws the connecting line markings that connect the grid markings to each other while self-propelling in addition to drawing the grid markings for each grid point position, the inking device will execute all the inking on the floor surface, and the inking work by the worker can be eliminated.

Effect of the Invention

[0024] As can be understood from the above description, according to the inking device and the inking method of the present invention, measurement errors and reading errors of the design drawings can be eliminated, and the time required for inking can be shortened.

Mode for Carrying Out the Invention

[0026] Hereinafter, an inkjet device and an inkjet method according to an embodiment will be described with reference to the accompanying drawings. In the present specification and the drawings, substantially the same components may be denoted by the same reference numerals, and redundant descriptions may be omitted.

[0027] [Inkjet Device and Inkjet Method According to Embodiment] With reference to FIGS. 1 to 8, an example of an inkjet device and an inkjet method according to an embodiment will be described. Here, FIG. 1 is a diagram showing a state in which an inkjet device and a measuring instrument according to an embodiment are disposed on a floor surface to be inkjet. FIG. 2 is a diagram showing an example of the hardware configuration of a control device included in the inkjet device according to the embodiment together with peripheral devices, and FIG. 3 is a diagram showing an example of the functional configuration of the control device.

[0028] The inkjet device 30 shown in FIG. 1 is a device that reads inkjet source drawing data, self-propels on a concrete floor surface F while specifying its own three-dimensional position information, and performs inkjet on the floor surface F which is the inkjet surface.

[0029] The inkjet device 30 has a traveling carriage 10 that travels on wheels 12, and the traveling carriage 10 incorporates a control device 20 that controls various devices. Further, the traveling carriage 10 is equipped with a plurality (two in the illustrated example) of targets 14A and 14B with different heights that receive light waves L1 and L2 irradiated from a measuring instrument 40 installed at a reference position P on the floor surface F. Additionally, the traveling carriage 10 is equipped with a receiver 13 such as an antenna that receives the three-dimensional position data of the traveling carriage 10 transmitted from the measuring instrument 40. The targets 14A and 14B are formed by, for example, prisms, and due to the different heights of both, it becomes possible to clearly distinguish the received data from both targets 14A and 14B. Note that three or more targets with different heights may be mounted on the traveling carriage 10.

[0030] The reference position P is a point whose three-dimensional position information is specified, and the measuring instrument 40 installed at the reference position P has its three-dimensional position information. Here, the measuring instrument 40 is, for example, a total station that automatically tracks the self-propelled inkjet device 30.

[0031] The light waves L1 and L2 irradiated from the measuring instrument 40 are respectively reflected by the targets 14A and 14B of the traveling inkjet device 30, and the measuring instrument 40 receives the reflected light waves L1 and L2. By measuring the received light waves L1 and L2 with the measuring instrument 40, the distance, vertical angle, and horizontal angle between the target 14 and the target 14 (inkjet device 30) are obtained, and the three-dimensional position of the target 14 (inkjet device 30) is specified.

[0032] The three-dimensional position data specified by the measuring instrument 40 is transmitted from the measuring instrument 40 to the receiver 13 as a signal S. Through the receiver 13, the inkjet device 30 receives its own three-dimensional position data and specifies its position information on the floor surface F each time.

[0033] Note that a plurality of measuring instruments 40 may be installed on the floor surface F. Further, if the inkjet device is equipped with a GPS, instead of receiving the measurement data from the measuring instrument and specifying its own position information, it may receive and specify its own position information with the GPS.

[0034] Next, with reference to FIGS. 2 and 3, the hardware configuration and functional configuration of the control device 20 included in the inkjet device 30 will be described.

[0035] As shown in FIG. 2, the control device 20 includes a CPU (Central Processing Unit) 21, a main storage device 22, an auxiliary storage device 23, a communication IF (interface) 24, and an input / output IF 25 that are interconnected by a connection bus 26. The main storage device 22 and the auxiliary storage device 23 are computer-readable recording media. Note that the above-described components may be provided individually, or some of the components may not be provided.

[0036] The CPU 21 is also called an MPU (Microprocessor) or a processor, and the CPU 21 may be a single processor or a multi-processor. The CPU 21 is a central arithmetic processing unit that controls the entire control device 20 composed of a computer. The CPU 21, for example, expands a program stored in the auxiliary storage device 23 so that it can be executed in the work area of the main storage device 22, and controls peripheral devices through the execution of the program, thereby providing a function that meets a predetermined purpose.

[0037] The main memory device 22 stores computer programs executed by the CPU 21, data processed by the CPU 21, and the like. The main memory device 22 includes, for example, a flash memory, a RAM (Random Access Memory), and a ROM (Read Only Memory). The auxiliary storage device 23 reads and writes various programs and various data to and from a recording medium, and is also called an external storage device. The auxiliary storage device 23 stores, for example, an OS (Operating System), various programs, various tables, and the like. The OS includes, for example, a communication interface program that transfers data to and from external devices connected via the communication IF 24. The external devices include, for example, communicators (none of which are shown) provided in the measuring instrument 40. Note that the network includes public networks such as the Internet, wireless networks such as mobile phone networks, private networks such as VPNs (Virtual Private Networks), LANs (Local Area Networks), and the like.

[0038] The auxiliary storage device 23 is used, for example, as a storage area that supplements the main memory device 22, and stores computer programs executed by the CPU 21, data processed by the CPU 21, and the like. The auxiliary storage device 23 is a silicon disk including a non-volatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD) device, a solid state drive device, or the like. In addition, as the auxiliary storage device 23, a drive device for a removable recording medium such as a CD drive device, a DVD drive device, or a BD drive device is exemplified, and as the removable recording medium, a CD, a DVD, a BD, a USB (Universal Serial Bus) memory, an SD (Secure Digital) memory card, or the like is exemplified.

[0039] The communication IF24 is an interface with the network to which the control device 20 is connected. The three-dimensional position data of the inkjet device 30 transmitted from the measuring instrument 40 is received by the receiver 13 via the network, and the three-dimensional position data is sent from the receiver 13 to the communication IF24 of the control device 20.

[0040] The input / output IF25 is an interface for inputting and outputting data with the devices connected to the control device 20. Connected to the input / output IF25 are, for example, input devices such as a keyboard, a pointing device such as a touch panel or a mouse, and a microphone. The control device 20 receives operation instructions and the like from an operator who operates the input device via the input / output IF25.

[0041] Also, connected to the input / output IF25 are, for example, display devices such as a liquid crystal panel (LCD: Liquid Crystal Display) and an organic EL panel (EL: Electroluminescence), and output devices such as a printer and a speaker. For example, the inkjet source drawing data and the like read into the control device 20 are displayed on the display device constituting the input / output IF25.

[0042] As shown in FIG. 3, the control device 20 provides various functions of at least the communication unit 201, the position specifying unit 202, the reading unit 203, the traveling unit 204, and the drawing unit 205 by executing a program by the CPU 21. Note that at least a part of the above processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or the like. Similarly, at least a part of the above processing functions may be a dedicated LSI (large scale integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, an image processing processor, or other digital circuits.

[0043] The communication unit 201 receives the three-dimensional position data of the inkjet device 30 transmitted from the measuring instrument 40 to the receiver 13 via the network.

[0044] Based on the three-dimensional position data received by the communication unit 201, the position-specific unit 202 specifies the current three-dimensional position data of the inkjet device 30 each time.

[0045] Based on the inkjet source drawing data obtained by transmission via a detachable recording medium or a network, the reading unit 203 reads the position information of each grid line recorded in the inkjet source drawing data, the position information of the grid points of the grid lines that intersect each other, etc. (inkjet information). Further, based on the read inkjet information, the reading unit 203 sets the order of inkjet at each inkjet point.

[0046] Based on the inkjet order set by the reading unit 203 and the position information of the inkjet device 30 specified by the position-specific unit 202, the traveling unit 204 drives the wheels 12 to move the carriage 10 to a predetermined position. The wheels 12 are provided with a motor as a drive source, and the motor is driven using the battery 15 as a power source. Here, the carriage 10 incorporates a gyro sensor 16 and an encoder 17, and these are connected to the control device 20 wirelessly or by wire. The gyro sensor 16 specifies the traveling direction of the carriage 10, and the encoder 17 specifies the traveling distance of the carriage 10 from the rotation speed of the wheels 12.

[0047] Based on the drawing rule information stored in the storage unit 206, the drawing unit 205 draws grid markings corresponding to the intersection form at the grid positions where a plurality of members (building materials such as runners) intersect each other. Further, connection line markings that connect a plurality of grid markings according to the intersection form are drawn. Note that the latter connection line markings may be drawn by a plurality of workers.

[0048] When drawing, the drawing unit 205 drives the XYZ plotter 18 to move the inkjet 19 to the drawing point, and operates the inkjet 19 at the drawing point to execute the drawing.

[0049] Next, referring to FIG. 4, the drawing rule information referred to by the drawing unit 205 during drawing will be described. Here, FIG. 4 is a diagram showing an example of grid markings included in the drawing rule information, FIG. 4(a) is a diagram showing a grid stamp, and FIGS. 4(b) to (d) are diagrams showing cross-shaped stamps.

[0050] The grid stamp s1 shown in FIG. 4(a) is a stamp indicating the grid positions where a plurality of members, including the sizes of members such as runners that intersect each other, intersect, and is included in the grid marking m1.

[0051] The grid stamp s1 in the illustrated example is a square stamp, and inside it, "65" indicating that the size of a member such as a runner intersecting this grid is 65 mm is illustrated. This size includes various sizes such as 50 mm, 75 mm, 90 mm, 100 mm, etc. The reading unit 203 reads the size of the member from the inked original drawing data, and a number corresponding to the size is stamped together with the square stamp.

[0052] The cross-shaped stamp s2 shown in FIG. 4(b) is a stamp indicating a cross shape where, for example, two members such as runners intersect at a grid position, and this is also included in the grid marking m1. The cross-shaped stamp s2 in the illustrated example is an L-shaped stamp.

[0053] The cross-shaped stamp s3 shown in FIG. 4(c) is a stamp indicating a cross shape where two or three members such as runners intersect in a T shape at a grid position, and this is also included in the grid marking m1. The cross-shaped stamp s3 in the illustrated example is a T-shaped stamp.

[0054] The cross-shaped stamp s4 shown in FIG. 4(d) does not strictly indicate a cross shape but is a stamp indicating an opening such as a window or a door. In this specification, such a stamp indicating an opening is also formally included in the cross-shaped stamps. The cross-shaped stamp s4 regarding the opening in the illustrated example is a U-shaped stamp.

[0055] In this way, in the control device 20, the reading unit 203 reads the inkjet source drawing data, and the drawing unit 205 refers to the grid markings m1 (grid stamps s1, intersection form stamps s2 to s4, etc.) included in the drawing rule information stored in the storage unit 206 and executes inkjetting to draw the corresponding grid markings m1 on the floor surface F.

[0056] Next, with reference to FIGS. 5 to 8, an inkjet method executed by the inkjet device 30 based on the actual inkjet source drawing data will be described. Here, FIG. 5 is a diagram showing an enlarged part of an example of the inkjet source drawing data. FIGS. 6(a), (b), and (c) are diagrams showing the grid markings of the VIa part, VIb part, and Vic part of FIG. 5, respectively. Further, FIG. 7 is a diagram showing the grid markings drawn at a predetermined position based on the inkjet source drawing data shown in FIG. 5, and FIG. 8 is a diagram further showing the connection line markings connecting the respective grid markings drawn at the predetermined position shown in FIG. 7.

[0057] In the inkjet source drawing data d shown in FIG. 5, members such as a plurality of runners intersect in various modes, and there are also openings.

[0058] In the control device 20, in the reading unit 203, for example, regarding three locations of the VIa part, VIb part, and Vic part shown in FIG. 5, grid markings are drawn based on the drawing rule information.

[0059] Since the VIa part shown in FIG. 5 is a grid position where two members such as runners intersect in an orthogonal mode, as shown in FIG. 6(a), for the cross-shaped grid stamp s1 with the size 65 (mm) of the orthogonal runners drawn, an intersection form stamp s2 with an L shape rotated as desired according to the orthogonal mode is further drawn. Here, in the illustrated example, two intersection form stamps s2 are drawn so that the intersection form is easily visible, but only one intersection form stamp s1 may be drawn.

[0060] On the one hand, since the VIb part shown in FIG. 5 is the grid point where members such as two runners intersect in a T shape, as shown in FIG. 6(b), with respect to the square grid stamp s1 on which the size 65 (mm) of the runner intersecting in a T shape is drawn, a T-shaped intersection form stamp s3 is further drawn at the position where the vertical line of the T shape intersects (in the example shown in the figure, the lower position).

[0061] Furthermore, since the VIc part shown in FIG. 5 is the location of the left and right ends of the opening, as shown in FIG. 6(c), two U-shaped intersection form stamps s3 including the size of the stud formed by a channel steel or the like are drawn in a manner where the webs of both face each other.

[0062] Based on the drawing rules shown in FIG. 6, while the inkjet device 30 travels on the floor surface F according to the set inkjet order, as shown in FIG. 7, at each grid point position on the floor surface F, a grid marking m1 corresponding to the intersection form is drawn.

[0063] Next, as shown in FIG. 8, while the inkjet device 30 travels, by drawing a connection line marking m2 that connects the grid markings m1 drawn on the floor surface F, the inkjet onto the floor surface F based on the inkjet original drawing data shown in FIG. 5 is executed.

[0064] As shown in FIGS. 7 and 8, by having the inkjet device 30 execute all the drawings of the grid marking m1 and the connection line marking m2, the inkjet by the operator can be completely eliminated and full automation of the inkjet can be achieved. Therefore, for example, by operating the inkjet device 30 at night to execute the inkjet, when the operator arrives at the site the next morning, the inkjet on the floor surface F will be completed.

[0065] On one hand, the inking device 30 executes the drawing of the grid marking m1 shown in FIG. 7, and the connection line marking m2 shown in FIG. 8 may be executed by a plurality of workers. By having the inking device 30 execute the drawing of the grid marking m1 for each grid position and having, for example, two workers perform the inking of the connection line marking m2 that connects the grid markings m1 to each other, the inking of the connection line marking m2 can be executed all at once simply by pulling the ink string upward and then releasing it. By separating the inking operation content that the inking device 30 is good at (reading the original drawing data for inking, specifying the position information of the device itself (equivalent to surveying), and the inking operation content that the worker is good at) and executing them separately, it is possible to realize an inking operation without mistakes while shortening the time required for inking.

[0066] In any method, it is possible to eliminate the surveying errors and the reading errors of the design drawings, which are problems in the inking by only workers, and it is possible to shorten the time required for inking.

[0067] In addition, other embodiments in which other components are combined with the configurations and the like described in the above embodiments may be possible, and the present invention is not limited to the configurations shown here at all. In this regard, it is possible to make changes without departing from the spirit of the present invention, and it can be appropriately determined according to the application form.
