Description

[Technical field]

[0001] The present invention relates to an embossing device, an embossing system, and a method of using the same. [Background technology]

[0002] In piping work, in order to install pipes on site according to design drawings, it is necessary to cut standard length pipes (pipe 1 in FIG. 13; for example, length: 5.5 m, 11 m, etc., nominal diameter: 150A, 200A, 400A, 4B, 6B, 8B, etc.) shipped from the factory to the required length (1a, 1b in FIG. 16). Before cutting the standard length pipe, the outer periphery of the standard length pipe is marked with a cutting position (20 in FIG. 13) and a groove preparation start position (21, 22 in FIG. 13; positions at a predetermined distance on both sides of the cutting position 20 as the center) for forming a welding groove (23, 24 in FIG. 16) when the pipes are butted together. When marking, it is necessary to measure the length from the end of the fixed-length pipe (including the remaining fixed-length pipe after cutting) to determine the marking position, but when the length is beyond a person's reach, it is impossible for one person to determine the marking position, so two people work together to use a tape measure to mark the cutting position and the start position of the groove preparation.

[0003] In addition, when standard length pipes are shipped from the factory, a stencil indicating the material, pipe diameter, and charge number (melt code number) is printed on the outer surface. When standard length pipes are cut, some of the cut pipes will not have a stencil, but it is necessary to be able to identify the stencil for each pipe. Therefore, before cutting the standard length pipe, the same content as the stencil printed on the standard length pipe is transcribed onto each section that will become a pipe in the future.

[0004] Furthermore, when the fixed length pipe is cut, it is necessary to be able to identify which part on the design drawing the cut pipe corresponds to, so before cutting the fixed length pipe, each part that will become the pipe in the future is stamped with a marking corresponding to the part number that corresponds to the pipe on the design drawing. Since the stamping work cannot be done until the cutting position is decided, it is done after the marking work. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 5-23475 [Patent Document 2] Japanese Patent Application Publication No. 11-57855 Summary of the Invention [Problem to be solved by the invention]

[0006] The following analysis is provided by the present inventors.

[0007] However, when two people work together to mark the work using a tape measure, it is difficult to perform the marking work when there is a shortage of manpower and it is not possible to form pairs. Also, if the stamping work is performed after the marking work, it is difficult to proceed with the work efficiently.

[0008] Therefore, it is conceivable to carry out marking and stamping work successively on a fixed-length pipe using a stamping device as described in Patent Documents 1 and 2. However, the stamping device described in Patent Documents 1 and 2 is much larger than the steel billet to be stamped, and is a large-scale device that is installed in a factory, so the places where marking and stamping work can be carried out successively are limited. In addition, with the stamping device described in Patent Documents 1 and 2, the burden of transporting the fixed-length pipe to the place where the stamping device is installed increases, so even if the fixed-length pipe can be transported and the marking and stamping work can be carried out successively, it is difficult to proceed with the work efficiently overall.

[0009] The main objective of the present invention is to provide a stamping device, stamping system, and method of use thereof that can contribute to enabling a single worker to efficiently perform marking and stamping work without being limited to a specific location. [Means for solving the problem]

[0010] A stamping device according to a first aspect comprises a base plate, a plurality of wheels rotatably arranged on the base plate and configured to roll on the outer peripheral surface of the tube in the tube axial direction, an optical distance meter fixed to the base plate and configured to measure and display the distance from a reflective surface of a reflector aligned with the end face of the tube using optical means to a predetermined reference position, an stamping machine fixed directly or indirectly to the base plate, stamping on the outer peripheral surface of the tube and arranged so that the stamping reference position is aligned with the predetermined reference position, and a controller fixed to the base plate and configured to receive stamping information from an operation terminal and control the stamping operation of the stamping machine based on the received stamping information.

[0011] The stamping system according to a second aspect includes the stamping device according to the first aspect, the reflector jig having the reflector and configured to be removably fixed to the tube with the reflective surface of the reflector aligned with the end face of the tube, and the operation terminal configured to transmit the stamping information to the controller in the stamping device.

[0012] A method of using the stamping system according to a third aspect is a method of using the stamping system according to the second aspect, and includes the steps of attaching and fixing the reflector jig to the tube so that the reflective surface of the reflector of the reflector jig is aligned with the end face of the tube, installing the stamping device on the tube, moving the stamping device to a predetermined position on the tube while measuring the distance from the reflective surface of the reflector of the reflector jig to the predetermined reference position of the optical rangefinder with the optical rangefinder of the stamping device, and transmitting stamping information from the operation terminal to the controller of the stamping device to operate the stamping machine to stamp. Effect of the Invention

[0013] The first to third aspects described above can contribute to enabling one worker to efficiently perform marking and stamping work without being limited to a specific location. [Brief description of the drawings]

[0017] The stamping device 100 is a device that stamps a mark (e.g., the marking portion 2 in FIG. 13) and an inscription (e.g., the inscription portion 3 in FIG. 13) at a predetermined position on the pipe 1 (see FIG. 1). Here, the pipe 1 includes not only a fixed length pipe at the time of shipment from the factory, but also a pipe with a part of the piping cut off. The stamping device 100 has a function of being movable along the pipe axis direction on the outer circumferential surface of the pipe 1 (see FIG. 14). The stamping device 100 can be made light enough to be carried by one user. The stamping device 100 has a function of calculating a distance 11 from a reference position 156 of the optical distance meter 150 to the reflective surface of the reflector 201 from the difference between the wavelength of the reflected light reflected by irradiating light (e.g., a laser) onto the reflective surface of the reflector 201 of the reflector jig 200 positioned on the end face of the pipe 1 and the wavelength of the internal reference (see FIG. 1). The main components of the stamping device 100 include a base plate 110, shaft members 112a, 112b, wheels 113a-113d, levels 114a, 114b, handles 115a, 115b, brackets 120, 121, knurled knobs 122a, 122b, a stamping machine 130, a weight member 140, an optical rangefinder 150, a stopper 160, and a controller 170 (see Figures 2-10).

[0018] Here, in the marking section 2 of the pipe 1, a circular arrow mark is stamped at the cutting position, and an arrow mark is stamped at the start position of groove preparation (a position at a predetermined distance on both sides in the longitudinal direction from the cutting position) for forming a groove for welding when the pipes are butted together (see Fig. 13). In addition, in the marking section 3 of the pipe 1, for example, the material is stamped in the first line, the charge number (factory shipment number) in the second line, and a mark (stencil) relating to the part number in the third line is stamped (see Fig. 13).

[0019] The base plate 110 is a plate-like member (see Figs. 1 to 8 and 10). Shaft members 112a, 112b are attached and fixed to predetermined positions on the bottom surface of the base plate 110. Levels 114a, 114b, handles 115a, 115b, bracket 120, weight member 140, optical rangefinder 150, and controller 170 are attached and fixed to predetermined positions on the top surface of the base plate 110. The base plate 110 has a window 111 that opens the main body. Part of the components of the stamp machine 130 is inserted through the window 111. A stopper 160 is attached to a predetermined position of the base plate 110 so as to be movable in the axial direction (perpendicular to the surface of the base plate 110) by rotation.

[0020] The shaft members 112a and 112b are axially shaped members fixed at predetermined positions on the bottom surface of the base plate 110 (see FIGS. 2, 3, 6, 7, and 10). The shaft members 112a and 112b are spaced apart from each other. The axes of the shaft members 112a and 112b are arranged substantially parallel to each other. Wheels 113a and 113b are rotatably attached to both ends of the shaft member 112a. Wheels 113c and 113d are rotatably attached to both ends of the shaft member 112b.

[0021] The wheels 113a to 113d are wheel-shaped members that roll on the outer circumferential surface of the tube 1 in the tube axial direction (see Figs. 1 to 6 and 10). The wheels 113a and 113b are rotatably attached to both ends of the shaft member 112a. The wheels 113c and 113d are rotatably attached to both ends of the shaft member 112b. The wheels 113a to 113d are rotatably disposed on the base plate 110 via the shaft members 112a and 112b. The outer circumferential surfaces (contact surfaces) of the wheels 113a to 113d are configured such that the diameter of the inner side of the rotating shaft (the body side of the shaft members 112a and 112b) is smaller than the outer diameter. This can improve the linearity of the marking device 100 in the tube axial direction on the outer circumferential surface of the tube 1. An elastic member can be used for at least the outer circumferential surfaces of the wheels 113a to 113d. This makes it possible to suppress slippage of the wheels 113a to 113d relative to the tube 1.

[0022] The levels 114a and 114b are instruments for measuring the horizontality of the base plate 110 (see FIGS. 1 to 4, 6, 7, and 10). The levels 114a and 114b are attached and fixed to predetermined positions on the upper surface of the base plate 110 (for example, positions near the shaft members 112a and 112b).

[0023] Handles 115a and 115b are hand-held members that facilitate handling of marking device 100. Handles 115a and 115b are attached and fixed to predetermined positions on the upper surface of base plate 110 (for example, positions at both ends in the longitudinal direction).

[0024] Bracket 120 is a support member for fixing bracket 121, which is fixed to stamp machine 130, to base plate 110 in such a manner that the position of bracket 121 can be adjusted (see Figs. 1 to 3, 5, 6, and 8). Bracket 120 is attached and fixed to a position near window 111 on the upper surface of base plate 110. Bracket 120 has a portion extending above the upper surface of base plate 110, and has grooves 123a and 123b in that portion. Grooves 123a and 123b are through openings for fixing bracket 121 so that it can be moved up and down by rotating and fastening knurled knobs 122a and 122b. Grooves 123a and 123b make stamp machine 130 height adjustable so that it can be applied to standard length pipes of various pipe diameters (for example, 150A to 400A).

[0025] Bracket 121 is a support member for fixing stamp machine 130 to bracket 120 so that its position can be adjusted (see Figs. 1 to 3, 5, 6, and 8). Bracket 121 is fixed to stamp machine 130. Bracket 121 is fixed to bracket 120 so as to be movable up and down by rotational fastening of knurled knobs 122a and 122b inserted into grooves 123a and 123b.

[0026] The knurled knobs 122a and 122b are fastening members for fixing the bracket 121 to the bracket 120 in a position adjustable manner. The knurled knobs 122a and 122b allow the bracket 121 to move up and down along the grooves 123a and 123b when loosened, and fix the bracket 121 to the bracket 120 when tightened.

[0027] The stamping machine 130 is a device that stamps a mark (e.g., the marking section 2 in FIG. 13) and a mark (e.g., the marking section 3 in FIG. 13) at a predetermined position on the pipe 1 (see FIGS. 1 to 9). The stamping machine 130 is attached and fixed to the bracket 121. The stamping machine 130 is supported on the base plate 110 via the bracket 121, the knurled knobs 122a and 122b, and the bracket 120. The stamping machine 130 may be supported directly on the base plate 110. The stamping machine 130 can be moved up and down relative to the base plate 110 by loosening the knurled knobs 122a and 122b and moving the stamping machine 130 up and down along the grooves 123a and 123b of the bracket 120. A part of the components of the stamping machine 130 is inserted through the window 111 of the base plate 110. The stamp machine 130 stamps the pipe 1 disposed under the base plate 110. The stamp machine 130 is connected to the controller 170 so as to be able to communicate (by wired communication or wireless communication). The stamp machine 130 stamps under the control of the controller 170. The stamp reference position (e.g., the stamp start position) of the stamp machine 130 is disposed so as to coincide with the reference position 156 of the optical rangefinder 150.

[0028] Weight member 140 is a member for suppressing vibrations that occur when stamping machine 130 is in operation (see Figs. 2 to 5 and 8). Weight member 140 also plays a role in balancing the weight of stamping device 100. Weight member 140 is disposed in the vicinity of stamping machine 130. Weight member 140 is attached and fixed in a position in the vicinity of window portion 111 on the upper surface of base plate 110, on the opposite side of window portion 111 from the attachment position of bracket 120.

[0029] The optical range finder 150 is a measuring instrument that measures the distance from a reference position 156 to a target (here, the reflective surface of the reflector 201 of the reflector jig 200 positioned on the end face of the tube 1) by optical means (see Figs. 1 to 5 and 9). The optical range finder 150 mainly comprises a light output unit 151, a light receiving unit 152, an operation unit 153, a display unit 154, and a control unit 155. The light output unit 151 is a functional unit that outputs light of a predetermined wavelength (e.g., laser light). The light receiving unit 152 is a functional unit that irradiates light (e.g., laser) on the reflective surface of the reflector 201 of the reflector jig 200 positioned on the end face of the tube 1, receives reflected light, and detects the wavelength of the reflected light. The operation unit 153 is a functional unit that receives operations by a user. The display unit 154 is a functional unit that displays the measured distance, etc. The control unit 155 controls each of the functional units 151 to 154, and calculates the distance 11 from the reference position 156 of the optical rangefinder 150 to the reflecting surface of the reflector 201 from the difference between the wavelength of the reflected light detected by the light receiving unit 152 and the wavelength of an internal reference.

[0030] Stopper 160 is a member that restricts the movement of stamping device 100 (see Figs. 1, 2, 4 to 7, and 10). Stopper 160 is attached to a predetermined position on base plate 110 so as to be movable in the axial direction (perpendicular to the surface of base plate 110) by rotation. Stopper 160 penetrates base plate 110, and a grounding member 161 is attached and fixed to the tip portion below base plate 110. Grounding member 161 restricts the movement of stamping device 100 by being pressed against the outer circumferential surface of tube 1.

[0031] The controller 170 is a device that controls the stamp machine 130 (see Figs. 1 to 7 and 9). The controller 170 is attached and fixed at a predetermined position on the upper surface of the base plate 110. The controller 170 is connected to the stamp machine 130 so as to be able to communicate (wired communication or wireless communication). The controller 170 is connected to the operation terminal 300 so as to be able to communicate (wired communication or wireless communication). The controller 170 receives stamp information related to the marking and stamping from the operation terminal 300, and controls the stamping operation of the stamp machine 130 based on the received stamp information.

[0032] The reflector jig 200 is a jig equipped with a reflector 201 that reflects light from the optical distance meter 150 of the marking device 100 at a position aligned with the end face of the pipe 1 (see Figs. 1, 11, 12, and 14). The reflector jig 200 is configured so as to be detachably fixed to the pipe 1. The reflector jig 200 mainly comprises the reflector 201, brackets 202, 203, and 204, a handle 205, a level 206, and mounting screws 207.

[0033] The reflector 201 is a plate-like member that reflects light from the optical rangefinder 150 (see FIGS. 1 and 11). The reflector 201 is attached and fixed to a bracket 202 so that the end face of the tube 1 and the reflective surface of the reflector 201 coincide with each other when the reflector jig 200 is fixed to the tube 1.

[0034] The bracket 202 is a member that supports the reflector 201 (see Figs. 1, 11, and 12). When the reflector jig 200 is fixed to the pipe 1, the bracket 202 abuts against the end face of the pipe 1, and positions the reflector jig 200 with respect to the end face of the pipe 1. The reflector 201 is attached and fixed so that the abutment surface of the bracket 202 with the end face of the pipe 1 and the reflecting surface of the reflector 201 are flush with each other.

[0035] Bracket 203 is a member that comes into contact with the outer circumferential surface of pipe 1 when reflector jig 200 is fixed to pipe 1, and determines the position of reflector jig 200 relative to the outer circumferential surface of pipe 1 (see Figs. 1, 11, and 12). Bracket 203 is attached and fixed to bracket 202. A handle 205 and a level 206 are attached and fixed to predetermined positions on the upper surface of bracket 203.

[0036] The bracket 204 is a member that is disposed radially inwardly away from the inner circumferential surface of the pipe 1 when the reflector jig 200 is fixed to the pipe 1 (see FIG. 12). The bracket 204 is screwed with the mounting screw 207 so that the mounting screw 207 passes through the bracket 204.

[0037] The handle 205 is a member that can be gripped by hand to facilitate handling of the reflector jig 200 (see FIGS. 1, 11, and 12). The handle 205 is attached and fixed to a predetermined position on the upper surface of the bracket 203.

[0038] The level 206 is an instrument for measuring the horizontality of the bracket 203 (see FIGS. 1, 11, and 12). The level 206 is attached and fixed to a predetermined position on the upper surface of the bracket 203.

[0039] The mounting screw 207 is a screw for attaching and fixing the reflector jig 200 to the pipe 1 (see FIG. 12). The mounting screw 207 is screwed into the bracket 204 so as to penetrate through the bracket 204. By tightening the mounting screw 207, the tip of the mounting screw 207 can be pressed against the inner circumferential surface of the pipe 1. By loosening the tightening of the mounting screw 207, the tip of the mounting screw 207 can be released from the inner circumferential surface of the pipe 1, and the reflector jig 200 can be removed from the pipe 1.

[0040] The operation terminal 300 is a terminal for operating the stamp machine 130 via the controller 170 (see Figs. 1 and 9). For example, a smartphone, a tablet terminal, or a notebook personal computer can be used as the operation terminal 300. The operation terminal 300 is connected to the controller 170 so as to be able to communicate (wireless communication or wired communication). The operation terminal 300 receives input of stamp information related to the marking and stamping for controlling the stamp machine 130, and transmits the input stamp information to the controller 170.

[0041] Next, a method of using the embossing system according to the embodiment 1 will be described with reference to the drawings. Fig. 15 is a flow chart that shows a schematic diagram of a method of using the embossing system according to the embodiment 1. Note that, for the configurations of the embossing device, the reflector jig, and the operation terminal, please refer to Figs. 1 to 14.

[0042] First, the reflecting surface of the reflector 201 of the reflector jig 200 is aligned with the end face of the tube 1 and the level 206 of the reflector jig 200 indicates horizontality, and the reflector jig 200 is attached and fixed to the tube 1 (step A1).

[0043] Next, the stamping device 100 is placed on the pipe 1 so that the levels 114a, 114b of the stamping device 100 indicate the horizontal state (step A2).

[0044] Next, while measuring the distance 11 from the reflective surface of the reflector 201 of the reflector jig 200 to the reference position 156 of the optical rangefinder 150 of the stamping device 100 with the optical rangefinder 150 of the stamping device 100, the stamping device is moved to the marking position (cutting position, groove preparation start position) of the pipe 1 so that the spirit levels 114a, 114b of the stamping device 100 indicate horizontality (step A3).

[0045] Next, stopper 160 of stamping device 100 is applied so that grounding member 161 of stamping device 100 comes into contact (presses) with pipe 1 at the marking position (cutting position, groove preparation start position) on pipe 1 (step A4).

[0046] Next, the operation terminal 300 transmits marking information to the controller 170 of the marking device 100 to operate the marking machine 130, and marks (marking related to the cutting position and the groove processing start position) (step A5). Note that the marking may be performed by separately aligning the cutting position and the groove processing start position.

[0047] Next, at the marking position (cutting position, groove preparation start position) on the pipe 1, the stopper 160 of the stamping device 100 is released so that the ground contact member 161 of the stamping device 100 moves away from the pipe 1 (step A6).

[0048] Next, the marking device 100 is moved to the marking position on the tube 1 (step A7).

[0049] Next, the stopper 160 of the stamping device 100 is applied so that the grounding member 161 of the stamping device 100 comes into contact (presses) with the tube 1 at the marking position on the tube 1 (step A8).

[0050] Finally, the operation terminal 300 transmits stamping information related to the marking to the controller 170 of the marking device 100 to operate the marking machine 130 and stamp the mark (step A9). Note that although the process ends after step A9, if the marking and marking are to be further added to another position, steps A3 to A9 are carried out.
