Description

The present invention relates to an embossing device, an embossing system, and a method for using the same.

In piping work, in order to install pipes on site according to the design drawings, factory-shipped standard-length pipes (pipe 1 in Figure 13; for example, length: 5.5 m, 11 m, etc., nominal diameter: 150A, 200A, 400A, 4B, 6B, 8B, etc.) must be cut to the required length (1a, 1b in Figure 16). Before cutting the standard-length pipe, the outer surface of the standard-length pipe is marked with the cutting position (20 in Figure 13) and the start position of the groove preparation (21, 22 in Figure 13; positions a specified distance on both sides of the cutting position 20 in the longitudinal direction) to form the welding grooves (23, 24 in Figure 16) when the pipes are butted together. During marking work, the length from the end of the standard length pipe (including the remaining standard length pipe after cutting) must be measured to determine the marking position, but when the length exceeds the reach of a human hand, it is not possible 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 for bevel processing.

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. However, it is necessary to be able to identify the stencil for each pipe. Therefore, before cutting the standard length pipe, the same stencil as that printed on the standard length pipe is transcribed onto each section that will become the pipe in the future.

Furthermore, once the standard length pipe is cut, it is necessary to be able to identify which part on the blueprint the cut pipe corresponds to. Therefore, before cutting the standard length pipe, each section that will become the pipe in the future is stamped with the same part number as the part number corresponding to the pipe on the blueprint. The stamping work cannot be done until the cutting position has been determined, so it is done after the marking work has been done.

Japanese Utility Model Application Laid-Open Publication No. 5-23475 Japanese Patent Application Publication No. 11-57855

The following analysis is provided by the inventors of the present application.

However, when two people work together to mark the work using a tape measure, it becomes difficult to carry out the marking work when there is a shortage of personnel and it is not possible to form pairs. Also, if the stamping work is carried out after the marking work, it becomes difficult to carry out the work efficiently.

One possible solution is to use a stamping device such as those described in Patent Documents 1 and 2 to perform scribing and stamping operations consecutively on fixed-length pipes. However, the stamping devices described in Patent Documents 1 and 2 are much larger than the steel billets that are the targets of stamping, and are large-scale devices that are installed in factories, limiting the locations where scribing and stamping operations can be performed consecutively. Furthermore, the stamping devices described in Patent Documents 1 and 2 increase the burden of transporting fixed-length pipes to the location where the stamping device is installed, so even if the fixed-length pipes can be transported and scribing and stamping operations can be performed consecutively, it is difficult to carry out the work efficiently overall.

The main objective of the present invention is to provide a marking device, marking system, and method of use that can help a single worker efficiently perform marking and marking work without being limited to a specific location.

The marking device according to the first aspect comprises:
A base plate and
a plurality of wheels rotatably disposed on the base plate and configured to roll on the outer circumferential surface of the pipe in the pipe axial direction;
an optical distance meter that is fixed to the base plate and configured to measure and display the distance from a reflective surface of a reflector that is aligned with the end face of the pipe to a predetermined reference position using optical means;
a stamping machine fixed directly or indirectly to the base plate, stamping the outer peripheral surface of the pipe, and disposed so that a stamping reference position is aligned with the predetermined reference position;
a controller fixed to the base plate, configured to receive embossing information from an operation terminal and control the embossing operation of the embossing machine based on the received embossing information;
Equipped with.
Furthermore, the wheel is configured so that the inner diameter of the axle is smaller than the outer diameter.
The marking device according to the first aspect of the present invention is
a first bracket fixed to the base plate and configured to have a groove extending in a direction perpendicular to an upper surface of the base plate;
a second bracket fixed to the stamping machine;
a knurled knob configured to threadably engage with the second bracket through the groove and to allow the position of the second bracket to be adjusted along the groove;
Further provided are:
The marking device according to the second aspect of the first aspect is:
a weight member fixed to a predetermined position on the base plate to suppress vibrations during operation of the marking machine;
The weight member is fixed to the base plate in a juxtaposed relationship with the stamping machine.

The stamping system according to the second aspect comprises an stamping device according to aspect 1 or 2 of the first aspect, a jig for the reflecting plate having the reflecting surface of the reflecting plate aligned with the end face of the tube so as to be removably fixed to the tube, and the operating terminal configured to be able to transmit the stamping information to the controller in the stamping device.

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 pipe so that the reflective surface of the reflector of the reflector jig is aligned with the end face of the pipe, installing the stamping device on the pipe, moving the stamping device to a predetermined position on the pipe 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.

The first to third aspects mentioned above can contribute to enabling a single worker to efficiently perform marking and stamping work without being limited to a specific location.

The stamping device 100 stamps a mark (e.g., marking portion 2 in FIG. 13) and an inscription (e.g., inscription portion 3 in FIG. 13) at a predetermined position on the pipe 1 (see FIG. 1). Here, the pipe 1 includes not only standard-length pipes shipped from the factory, but also pipes with a portion of the piping cut off. The stamping device 100 has the ability to move along the axial direction of the outer surface of the pipe 1 (see FIG. 14). The stamping device 100 can be lightweight enough for a single user to carry. The stamping device 100 has the ability to calculate the distance 11 from the reference position 156 of the optical distance meter 150 to the reflective surface of the reflector 201 based on the difference between the wavelength of the reflected light (e.g., laser) irradiated 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 and 112b, wheels 113a-113d, levels 114a and 114b, handles 115a and 115b, brackets 120 and 121, knurled knobs 122a and 122b, a stamping machine 130, a weight member 140, an optical rangefinder 150, a stopper 160, and a controller 170 (see Figures 2 to 10).

The marking section 2 of the pipe 1 stamps a circular arrow mark at the cutting position and an arrow mark at the start position of the groove preparation (a predetermined distance on both sides of the cutting position in the longitudinal direction) for forming a welding groove when the pipes are butted together (see Figure 13). The marking section 3 of the pipe 1 also stamps, for example, the material in the first line, the charge number (factory shipping number) in the second line, and a marking (stencil) relating to the part number in the third line (see Figure 13).

The base plate 110 is a plate-shaped member (see Figures 1 to 8 and 10). Shaft members 112a and 112b are attached and fixed to predetermined positions on the bottom surface of the base plate 110. Levels 114a and 114b, handles 115a and 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 to the main body. Some of the components of the engraving machine 130 are inserted through the window 111. A stopper 160 is attached to a predetermined position on the base plate 110 so that it can move axially (perpendicular to the surface of the base plate 110) by rotation.

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

Wheels 113a-113d are wheel-shaped members that roll along the axial direction on the outer surface of the tube 1 (see Figures 1-6 and 10). Wheels 113a and 113b are rotatably attached to both ends of shaft member 112a. Wheels 113c and 113d are rotatably attached to both ends of shaft member 112b. Wheels 113a-113d are rotatably disposed relative to base plate 110 via shaft members 112a and 112b. The outer surfaces (contact surfaces) of wheels 113a-113d are configured so that the diameter on the inside of the rotation axis (the main body side of shaft members 112a and 112b) is smaller than the diameter on the outside. This improves the linearity of the marking device 100 along the outer surface of the tube 1 in the axial direction. An elastic material can be used for at least the outer surfaces of wheels 113a-113d. This reduces slippage of the wheels 113a-113d relative to the tube 1.

Levels 114a and 114b are instruments used to measure the horizontality of base plate 110 (see Figures 1 to 4, 6, 7, and 10). Levels 114a and 114b are fixedly attached to predetermined positions on the top surface of base plate 110 (for example, positions near shaft members 112a and 112b).

Handles 115a and 115b are hand-held components that facilitate handling of the marking device 100. Handles 115a and 115b are attached and fixed to predetermined positions on the top surface of base plate 110 (e.g., at both longitudinal ends).

Bracket 120 is a support member that secures bracket 121, which is fixed to stamping machine 130, to base plate 110 in an adjustable position (see Figures 1 to 3, 5, 6, and 8). Bracket 120 is attached and fixed to the base plate 110 in a position near window portion 111 on the top surface of base plate 110. Bracket 120 has a portion that extends above the top surface of base plate 110, and this portion has grooves 123a and 123b. Grooves 123a and 123b are through openings that secure bracket 121 so that it can be moved up and down by rotating and tightening knurled knobs 122a and 122b. Grooves 123a and 123b allow stamping machine 130 to be height-adjustable, allowing it to be used with standard-length pipes of various diameters (e.g., 150A to 400A).

Bracket 121 is a support member that secures stamping machine 130 to bracket 120 so that its position can be adjusted (see Figures 1 to 3, 5, 6, and 8). Bracket 121 is fixed to stamping machine 130. Bracket 121 is fixed to bracket 120 so that it can move up and down by rotating and tightening knurled knobs 122a and 122b inserted into grooves 123a and 123b.

Knurled knobs 122a and 122b are fastening members used to secure bracket 121 to bracket 120 in an adjustable position. When loosened, knurled knobs 122a and 122b allow bracket 121 to move up and down along grooves 123a and 123b, and when tightened, secure bracket 121 to bracket 120.

The stamping machine 130 is a device that marks (e.g., marking section 2 in Figure 13) and stamps (e.g., stamping section 3 in Figure 13) predetermined positions on the pipe 1 (see Figures 1 to 9). The stamping machine 130 is fixedly attached to the bracket 121. The stamping machine 130 is supported on the base plate 110 via the bracket 121, knurled knobs 122a and 122b, and bracket 120. The stamping machine 130 may also 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 it up and down along the grooves 123a and 123b of the bracket 120. Some of the components of the stamping machine 130 pass through the window 111 in the base plate 110. The stamping machine 130 stamps the pipe 1 arranged below the base plate 110. The stamping machine 130 is connected to the controller 170 so that it can communicate (wired or wireless communication). The stamping machine 130 stamps under the control of the controller 170. The stamping reference position (e.g., stamping start position) of the stamping machine 130 is arranged to coincide with the reference position 156 of the optical rangefinder 150.

The weight member 140 is a member that suppresses vibrations that occur when the stamping machine 130 is in operation (see Figures 2 to 5 and 8). The weight member 140 also serves to balance the weight of the stamping device 100. The weight member 140 is located near the stamping machine 130. The weight member 140 is attached and fixed near the window portion 111 on the top surface of the base plate 110, on the opposite side of the window portion 111 from the mounting position of the bracket 120.

The optical rangefinder 150 is a measuring instrument that uses optical means to measure 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 pipe 1) (see Figures 1 to 5 and 9). The optical rangefinder 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) onto the reflective surface of the reflector 201 of the reflector jig 200 positioned on the end face of the pipe 1, receives the reflected light, and detects the wavelength of the reflected light. The operation unit 153 is a functional unit that receives user operations. The display unit 154 is a functional unit that displays the measured distance, etc. The control unit 155 controls each of the functional units 151-154, and calculates the distance 11 from the reference position 156 of the optical rangefinder 150 to the reflecting surface of the reflector 201 based on the difference between the wavelength of the reflected light detected by the light receiving unit 152 and the internal reference wavelength.

The stopper 160 is a member that restricts the movement of the stamping device 100 (see Figures 1, 2, 4 to 7, and 10). The stopper 160 is attached to a predetermined position on the base plate 110 so that it can move axially (perpendicular to the surface of the base plate 110) by rotation. The stopper 160 penetrates the base plate 110, and a grounding member 161 is attached and fixed to the tip below the base plate 110. The grounding member 161 restricts the movement of the stamping device 100 by being pressed against the outer surface of the tube 1.

The controller 170 is a device that controls the engraving machine 130 (see Figures 1 to 7 and 9). The controller 170 is attached and fixed at a predetermined position on the top surface of the base plate 110. The controller 170 is connected to the engraving machine 130 so that it can communicate (wired or wireless communication). The controller 170 is connected to the operation terminal 300 so that it can communicate (wireless or wired communication). The controller 170 receives engraving information related to marking and stamping from the operation terminal 300, and controls the engraving operation of the engraving machine 130 based on the received engraving information.

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 Figures 1, 11, 12, and 14). The reflector jig 200 is configured to be removably 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 a mounting screw 207.

The reflector 201 is a plate-shaped member that reflects light from the optical rangefinder 150 (see Figures 1 and 11). The reflector 201 is attached and fixed to the bracket 202 so that the end face of the tube 1 and the reflective surface of the reflector 201 are aligned when the reflector jig 200 is fixed to the tube 1.

The bracket 202 is a member that supports the reflector 201 (see Figures 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, positioning the reflector jig 200 relative to the end face of the pipe 1. The reflector 201 is attached and fixed so that the abutting surface of the bracket 202 that abuts against the end face of the pipe 1 and the reflective surface of the reflector 201 are flush with each other.

Bracket 203 is a component that abuts against the outer surface of pipe 1 when reflector jig 200 is fixed to pipe 1, and positions reflector jig 200 relative to the outer surface of pipe 1 (see Figures 1, 11, and 12). Bracket 203 is attached and fixed to bracket 202. A handle 205 and a level 206 are attached and fixed at predetermined positions on the top surface of bracket 203.

The bracket 204 is a component that is positioned radially inward from the inner circumferential surface of the pipe 1 when the reflector jig 200 is fixed to the pipe 1 (see Figure 12). The bracket 204 is threadedly engaged with the mounting screw 207 so that the mounting screw 207 passes through it.

The handle 205 is a handheld component that makes it easy to handle the reflector jig 200 (see Figures 1, 11, and 12). The handle 205 is attached and fixed at a predetermined position on the top surface of the bracket 203.

The level 206 is an instrument used to measure the horizontality of the bracket 203 (see Figures 1, 11, and 12). The level 206 is attached and fixed at a predetermined position on the top surface of the bracket 203.

The mounting screw 207 is used to attach and secure the reflector jig 200 to the pipe 1 (see Figure 12). The mounting screw 207 threads into the bracket 204, passing through the bracket 204. By tightening the mounting screw 207, the tip of the mounting screw 207 can be pressed against the inner surface of the pipe 1. By loosening the mounting screw 207, the tip of the mounting screw 207 can be released from the inner surface of the pipe 1, allowing the reflector jig 200 to be removed from the pipe 1.

The operation terminal 300 is a terminal for operating the embossing machine 130 via the controller 170 (see Figures 1 and 9). The operation terminal 300 can be, for example, a smartphone, tablet terminal, or laptop personal computer. The operation terminal 300 is connected to the controller 170 so that it can communicate (wireless or wired). The operation terminal 300 receives input of embossing information related to marking and engraving to control the embossing machine 130, and transmits the input embossing information to the controller 170.

Next, the method of using the embossing system according to embodiment 1 will be explained using the drawings. Figure 15 is a flowchart that schematically illustrates the method of using the embossing system according to embodiment 1. Please refer to Figures 1 to 14 for the configuration of the embossing device, reflector jig, and operation terminal.

First, align the reflective surface of the reflector 201 of the reflector jig 200 with the end face of the pipe 1, and attach and fix the reflector jig 200 to the pipe 1 so that the level 206 of the reflector jig 200 indicates horizontality (Step A1).

Next, the stamping device 100 is placed on the pipe 1 so that the levels 114a and 114b of the stamping device 100 indicate horizontality (Step A2).

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 distance meter 150 of the stamping device 100 using the optical distance meter 150 of the stamping device 100, the stamping device is moved to the marking position (cutting position, groove processing start position) on the pipe 1 so that the levels 114a, 114b of the stamping device 100 indicate horizontality (Step A3).

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 pipe 1 at the marking position (cutting position, groove preparation start position) on the pipe 1 (step A4).

Next, marking information is sent from the operation terminal 300 to the controller 170 of the marking device 100, which activates the marking machine 130 and marks the markings (markings for the cutting position and the bevel processing start position) (step A5). Note that markings may be performed by aligning the cutting position and the bevel processing start position separately.

Next, at the marking position on the pipe 1 (cutting position, bevel processing start position), 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).

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

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 (pressed against) the pipe 1 at the marking position on the pipe 1 (step A8).

Finally, the operation terminal 300 sends stamping information to the controller 170 of the stamping device 100, which activates the stamping machine 130 and stamps the mark (step A9). Note that the process ends after step A9, but if you wish to further mark and stamp in another position, steps A3 to A9 will be performed.

According to embodiment 1, by using the portable marking device 100, marking and stamping related work can be performed in a single flow process, which contributes to efficient marking and stamping work by a single worker without being limited to a specific location.
