Description

  The present invention relates to a portable marking device that can be carried by an operator among marking devices that print characters, numbers, or other symbols on an object.

  For example, each steel produced through the steel production process is marked with a unique symbol, and thereafter product management is performed based on this symbol.

  As symbols to be marked on steel, Arabic numerals, alphabets, or a combination of both are frequently used.

  Usually, marking on steel is performed by an operator handwriting with paint, ink or other colored liquid on each steel.

  Symbols to be marked on each steel are predetermined, and the operator writes a symbol corresponding to the steel with a colored liquid on each steel while looking at the list in which the symbols are described for each steel. .

  Often, however, the operator misreads the list and writes the wrong symbol on the steel. Or, although you read the list correctly, you may accidentally write other symbols when writing symbols on steel.

  As described above, it is almost impossible to eradicate a list reading error or a symbol writing error by a conventional method in which an operator manually writes a symbol on each steel.

  Also, various marking devices using a robot have been proposed in order to reduce the work amount of the worker.

  For example, Japanese Patent Laid-Open No. 6-246476 (Patent Document 1) discloses a printing robot that is movable in the front-rear, left-right, and up-down directions above a surface plate on which a steel plate member is placed, and a marking laser attached to the printing robot. A marking device comprising a head and a sheet feeder of a thermal transfer material that is thermally transferred by laser light from a laser head, marked on the surface of the steel plate member, and homogenized on the surface of the steel plate member is proposed.

  Japanese Patent Laying-Open No. 2005-257429 (Patent Document 2) discloses a robot hand, a CCD camera attached to the robot hand, extraction means for extracting a defective part from an image captured by the CCD camera, and the defective part. A surface inspection apparatus with a marking function is provided.

  FIG. 8 is a block diagram of the portable marking device 100 according to the present embodiment having the following structure.

  The portable marking device 100 according to the present embodiment has a function of marking Arabic numerals, alphabets and other symbols on a surface 1601 of a steel 1600 (see FIG. 8), for example.

  The portable marking device 100 according to this embodiment includes a nozzle 110 (see FIGS. 3, 4, and 7) that sprays paint on the steel 1600 to be marked, and a horizontal direction 1702 (see FIG. 3). The first nozzle driving device 120 that is moved in Step 1, the second nozzle driving device 130 that moves the nozzle 110 in the vertical direction 1703 (see FIG. 3) orthogonal to the horizontal direction 1702, and the coating material that stores the coating material supplied to the nozzle 110 A tank 140, a compressed air tank 150 for storing compressed air, a control device 160 for controlling the operation of each of the nozzle 110, the first nozzle driving device 120 and the second nozzle driving device 130, a first nozzle driving device 120, A battery 170 as a power source for supplying power to each of the second nozzle driving device 130 and the control device 160. , A nozzle 110, a first nozzle driving device 120, a second nozzle driving device 130, a paint tank 140, a compressed air tank 150, a control device 160 and a housing 180 (see FIGS. 1 and 2) holding the battery 170, and the housing 180 The housing attachment means 190 which attaches | detaches with respect to the steel 1600, and the heat-resistant board 210 (refer FIG. 1) which has the opening part 211 are provided.

  The nozzle 110 is moved in the horizontal direction 1702 by the first nozzle driving device 120 and further moved in the vertical direction 1703 by the second nozzle driving device 130, and operates according to an on / off control signal transmitted from the control device 160. That is, a desired symbol (number, alphabet, barcode, etc.) is marked on the surface 1601 of the steel 1600 by repeatedly turning on / off the paint spray according to an on / off control signal transmitted from the control device 160.

  The nozzle 110 marks the steel 1600 with a symbol in a continuous one-stroke type according to an instruction by a transmission signal transmitted from the control device 160. The “continuous one-stroke type” is a format in which the nozzle 110 continuously moves along each line segment constituting the symbol to be marked, so that the nozzle 110 writes the symbol without stopping the marking operation halfway. Point to.

  The second nozzle driving device 130 that moves the nozzle 110 in the vertical direction 1703 includes a ball spline 121 (see FIGS. 3, 4, and 7) that extends in the horizontal direction 1702 and a first servo motor 122 (see FIGS. 3, 4, and 4). (See FIG. 7).

  As shown in FIGS. 3, 4 and 7, the ball spline 121 is rotatably supported between two support plates 181A and 181B which are spaced apart from each other in parallel.

  The nozzle 110 is attached to the ball spline 121 so as to be slidable along the ball spline 121, and the ball spline 121 is attached to a first servo motor 122 at one end thereof. As the first servo motor 122 rotates (forward or reverse), the nozzle 110 rotates in the vertical plane around the ball spline 121, and the tip of the nozzle 110 changes the position (height) in the vertical direction 1703. .

  The rotation direction (forward rotation or reverse rotation) and rotation amount of the first servo motor 122 are determined according to a control signal transmitted from the control device 160.

  Thus, the nozzle 110 moves in the vertical direction 1703 to the vertical position (height) designated by the control signal transmitted from the control device 160 via the first servo motor 122 and the ball spline 121. .

  The heat-resistant plate 210 is attached to the support plates 181A and 181B so as to be rotatable in the vertical plane, and the nozzle 110 is fitted into the opening 211 of the heat-resistant plate 210 from the inside. For this reason, when the nozzle 110 rotates around the ball spline 121, the heat-resistant plate 210 also rotates together with the nozzle 110 in synchronization therewith. For this reason, even if the nozzle 110 rotates, the tip of the nozzle 110 always faces the outside through the opening 211 of the heat-resistant plate 210.

  The first nozzle driving device 120 that moves the nozzle 110 in the horizontal direction 1702 includes a ball spline 121 (see FIGS. 3, 4, and 7) that extends in the horizontal direction 1702, and a second servo motor 131 (see FIGS. 3, 4, and 4). 7) and a timing belt 132.

  The nozzle 110 is attached to the ball spline 121 so as to be movable (slidable).

  The timing belt 132 is stretched between a timing pulley 133 disposed adjacent to the support plate 181A and a pulley (not shown) driven by the second servo motor 131. Therefore, the timing belt 132 is driven so as to travel in one direction or the opposite direction according to the rotation direction of the second servo motor 131 and moves by a distance corresponding to the rotation amount of the second servo motor 131.

  Further, the timing belt 132 is fixedly coupled to the nozzle 110 at one point. Therefore, the nozzle 110 moves in the horizontal direction 1702 (right or left direction in FIG. 3) according to the moving direction of the timing belt 132, and further moves in the horizontal direction 1702 according to the moving amount of the timing belt 132.

  Thus, in the horizontal direction 1702, the nozzle 110 moves to the horizontal position designated by the control signal transmitted from the control device 160 via the ball spline 121, the timing belt 132, and the second servo motor 131. .

  The two support plates 181A and 181B form part of a housing 180 (described later).

  As shown in FIG. 4, the paint tank 140 is attached to the inside of the housing 180 so as to be removable on the back side of the portable marking device 100.

  The paint tank 140 is filled with paint supplied to the nozzle 110, and the paint tank 140 and the nozzle 110 are connected via a paint pipe 141. The paint in the paint tank 140 is supplied to the nozzle 110 through the paint pipe 141 by the action of the compressed air supplied from the compressed air tank 150.

  As shown in FIG. 4, the compressed air tank 150 is attached to the inside of the housing 180 so as to be removable adjacent to the paint tank 140.

  The compressed air tank 150 is connected to both the paint tank 140 and the nozzle 110 via an air pipe 151, and the paint in the paint tank 140 is fed to the nozzle 110 by the compressed air supplied from the compressed air tank 150, Further, it is sprayed outward from the nozzle 110.

  As described above, the control device 160 transmits a control signal to each of the first nozzle driving device 120 and the second nozzle driving device 130, and determines the rotation direction and the rotation amount of the first servo motor 122 and the second servo motor 131. Control. The control device 160 further transmits an on / off control signal for controlling the opening / closing of the nozzle 110 to the nozzle 110 to control on / off of the spraying of the paint. The control device 160 marks a desired symbol on the surface 1601 of the steel 1600 by controlling the operations of the first nozzle driving device 120, the second nozzle driving device 130, and the nozzle 110 in this way.

  As shown in FIG. 4, the control device 160 is attached to the housing 180 so as to be removable adjacent to the paint tank 140 and the compressed air tank 150 on the back side of the portable marking device 100.

  As shown in FIG. 4, the battery 170 is attached inside the housing 180 so as to be removable adjacent to the paint tank 140, the compressed air tank 150 and the control device 160.

  As shown in FIG. 8, the battery 170 supplies the first nozzle driving device 120, the second nozzle driving device 130, and the control device 160 with electric power necessary for their operation.

  As shown in FIGS. 1 and 2, the housing 180 including the support plates 181A and 181B as a part includes a nozzle 110, a first nozzle driving device 120, a second nozzle driving device 130, a paint tank 140, and a compressed air tank 150. The controller 160 and the battery 170 are entirely covered. As shown in FIG. 2, the storage box 182 that covers the paint tank 140, the compressed air tank 150, the control device 160 and the battery 170 and is a part of the housing 180 includes the paint tank 140, the compressed air tank 150, and the control device 160. In addition, the battery 170 can be opened and closed so that the battery 170 can be taken out.

  The housing 180 is made of aluminum having a high heat dissipation property, and in order to further improve the heat dissipation property, the housing 180 is formed with a heat dissipation opening 183 over the whole.

  The front side of the housing 180 is open (see FIG. 7), and the heat-resistant plate 210 is attached to the opening region so as to be removable from the housing 180, as shown in FIG.

  The heat-resistant plate 210 has an opening 211, and the paint sprayed from the nozzle 110 passes through the opening 211 and reaches the surface 1601 of the steel 1600.

  The heat-resistant plate 210 is made of aluminum, and protects the inside of the housing 180 from heat radiated from the steel 1600 when the steel 1600 is still in a high temperature state. For this reason, when the steel 1600 is in a normal temperature state, the portable marking device 100 can be used with the heat-resistant plate 210 removed (see FIG. 7).

  As shown in FIG. 11, the housing attachment means 190 includes a handle 191 attached to the housing 180, a permanent magnet 192 attached to the lower end of the handle 191 located on the front side of the portable marking device 100, and a permanent magnet 192. And a magnet moving mechanism 194 that moves the permanent magnet 192 in the direction away from the steel 1600 with respect to the housing 180.

  The handle 191 has a shape close to an inverted U shape and has a handle function. That is, the operator can carry the portable marking device 100 with the handle 191.

  FIGS. 9A and 9B are schematic views showing the internal structure of the magnet moving mechanism 194. FIG.

  The magnet moving mechanism 194 includes a trigger lever 196, a spiral spring 197, a link lever 198, and a permanent magnet moving lever 199.

  A pin 195 is fixed to the inner wall of the handle 191, and the trigger lever 196 is attached to the pin 195 so as to be rotatable about the pin 195.

  The trigger lever 196 includes a first portion 196A extending in one direction from the pin 195 and a second portion 196B extending at an angle (preferably an angle of 90 degrees or less) with the first portion 196A from the pin 195 as a base point. .

  The spiral spring 197 is fitted into the pin 195 and biases the trigger lever 196 in the direction of the arrow 1704. One end of the spiral spring 197 is locked to the inner wall of the handle 191 and the other end is locked to a pin 197A fixed to the trigger lever 196.

  The permanent magnet moving lever 199 is a lever extending substantially in the horizontal direction, and one end thereof is fixedly attached to the permanent magnet 192.

  The link lever 198 is rotatably coupled to the second portion 196B of the trigger lever 196 at one end and is rotatably engaged to a pin 198A fixed to the inner wall of the handle 191 at the other end. Yes. Further, the link lever 198 is rotatably connected to the other end of the permanent magnet moving lever 199 at a position between both ends thereof and close to the pin 198A.

  The tip of the first portion 196A of the trigger lever 196 protrudes to the outside of the handle 191, and the operator moves the first portion 196A in the direction of the arrow 1704 (see FIG. 9A) and the opposite arrow 1705 (FIG. 9B). ))).

  The permanent magnet 192 is positioned between the first position shown in FIG. 9A and the second position shown in FIG. 9B according to the operations of the trigger lever 196, the link lever 198, and the permanent magnet moving lever 199. Reciprocate.

  In the first position, as shown in FIG. 9A, the permanent magnet 192 is attracted to the steel 1600 with the cover 193 interposed therebetween. That is, when the permanent magnet 192 is in the first position, the portable marking device 100 is attracted to the steel 1600.

  In the second position, the permanent magnet 192 is separated from the steel 1600 as shown in FIG. That is, when the permanent magnet 192 is in the second position, the portable marking device 100 is in a state separated from the steel 1600, and in this state, the portable marking device 100 can be detached from the steel 1600.

  When no force is applied to the first portion 196A of the trigger lever 196 (that is, when the operator does not rotate the first portion 196A of the trigger lever 196 in the direction of the arrow 1705), the trigger lever 196 9A is urged in the direction of arrow 1704 by the urging force of the spiral spring 197 as shown in FIG. For this reason, the permanent magnet 192 is pushed in the direction of the steel 1600 through the link lever 198 and the permanent magnet moving lever 199, and is the most distal end on the front surface (surface facing the steel 1600) side of the portable marking device 100. Is located. That is, the permanent magnet 192 is located at the first position. For this reason, the permanent magnet 192 is attracted to the surface 1601 of the steel 1600 through the cover 193 by the action of magnetic force, and as a result, the portable marking device 100 is attracted to the surface 1601 of the steel 1600.

  When the portable marking device 100 is removed from the steel 1600, the operator places the first portion 196A of the trigger lever 196 in the direction opposite to the arrow 1704 around the pin 195, that is, the direction of the arrow 1705 (FIG. 9B ))). As a result, the link lever 198 rotates counterclockwise about the pin 198A by an angle θ, and as a result, the permanent magnet moving lever 199 moves to an angle θ of the link lever 198 (FIG. 9B). 9) is pulled toward the left side of FIG. 9B by a distance corresponding to the rotation of (see). Thereby, the permanent magnet 192 moves from the first position to the second position. By maintaining the state where the trigger lever 196 is rotated in the direction of the arrow 1705, the permanent magnet 192 is maintained at the second position.

  As a result, the adsorption by the magnetic force of the permanent magnet 192 on the steel 1600 is released. That is, since the portable marking device 100 is not attracted to the surface 1601 of the steel 1600 by the magnetic force of the permanent magnet 192, the portable marking device 100 can be separated from the steel 1600.

  After the portable marking device 100 is pulled away from the steel 1600, the operator releases the trigger lever 196 (that is, stops urging the trigger lever 196), so that the trigger lever 196 is a spiral spring. By the action of the urging force of 197, it rotates in the direction of the arrow 1704 and returns to the state shown in FIG.

  As described above, the portable marking device 100 can be attracted to the surface 1601 of the steel 1600 by the magnetic force of the permanent magnet 192, and further, the trigger lever 196 is rotated in the direction of the arrow 1705 to carry the portable marking device 100. It is possible to pull the type marking device 100 away from the surface 1601 of the steel 1600. That is, the portable marking device 100 according to this embodiment can be detachably attached to the steel 1600.

  Note that the cover 193 is made of a nonmagnetic material (for example, a synthetic resin such as plastic), and prevents iron powder or other metal powder having magnetic force from adhering to the permanent magnet 192.

  Note that the total weight of the portable marking device 100 according to the present embodiment is set to about 3 to about 3.5 kg to facilitate carrying.

  A method of using the portable marking device 100 according to this embodiment having the above structure will be described below.

  In the normal state, the permanent magnet 192 is in the first position shown in FIG. 9A by the action of the urging force of the spiral spring 197. For this reason, by bringing the front side of the portable marking device 100 into contact with the surface 1601 of the steel 1600, the permanent magnet 192 and thus the portable marking device 100 can be attracted to the steel 1600.

  Next, marking data is input to the control device 160. For example, the marking data can be input to the control device 160 via a radio signal from an upper central processing device at a remote location. Alternatively, it is also possible to input directly to the control device 160 via Bluetooth (registered trademark) or other wireless signals using a portable wireless transmission device held by an operator.

  When receiving the marking data and the marking operation start instruction signal, the control device 160 transmits a control signal corresponding to the received marking data to each of the first nozzle driving device 120 and the second nozzle driving device 130. The second servo motor 131 of the first nozzle driving device 120 and the first servo motor 122 of the second nozzle driving device 130 rotate in the direction instructed by the control signal and rotate by the amount instructed by the control signal.

  The control device 160 further transmits an on / off control signal for controlling the opening and closing of the nozzle 110 to the nozzle 110. The nozzle 110 turns on and off the paint spraying port according to an on / off control signal.

  The operations of the first nozzle driving device 120, the second nozzle driving device 130, and the nozzle 110 are controlled by the control device 160 in this manner, whereby the symbol designated by the marking data is marked on the surface 1601 of the steel 1600. .

  For example, a work end lamp may be provided in the portable marking device 100 and the work end lamp may be turned on when marking is completed.

  After marking, when the operator rotates the first portion 196A of the trigger lever 196 in the direction of the arrow 1705, as described above, the permanent magnet 192 is moved from the first position (FIG. 9A) to the second position. Move to the position (FIG. 9B). Thereby, the portable marking device 100 can be detached from the steel 1600.

  When the operator releases his hand from the first portion 196A of the trigger lever 196 (that is, when the biasing of the first portion 196A of the trigger lever 196 in the direction of the arrow 1705 is stopped), the biasing force of the spiral spring 197 is applied. The permanent magnet 192 returns from the second position (FIG. 9B) to the first position (FIG. 9A).

  Thereafter, the same operation can be repeated for the other steel 1600.

  As described above, according to the portable marking device 100 according to the present embodiment, it is no longer necessary for the operator to manually mark the surface 1601 of the steel 1600 as in the conventional case, and the amount of work in the marking operation is reduced. It becomes possible to make it.

  Further, it is possible to eliminate writing mistakes accompanying handwriting by the operator, and to improve the quality of subsequent product management for the steel 1600.

  Conventionally, even in a narrow space where the operator cannot perform marking without entering, as long as there is a space for inserting the portable marking device 100, desired marking is performed on the surface 1601 of the steel 1600. Thus, even if the space for writing work is limited, the writing work can be surely performed.

  In addition, the portable marking device 100 according to the present embodiment is not limited to the above configuration, and various modifications can be made with respect to the configuration.

  For example, in the portable marking device 100 according to the present embodiment, the nozzle 110 is driven in the horizontal direction and the vertical direction by the first nozzle driving device 120 and the second nozzle driving device 130. It is also possible to use other types of driving devices.

  Moreover, although the housing attachment means 190 in the portable marking device 100 according to the present embodiment is configured to have one permanent magnet 192, the number of permanent magnets 192 is not limited to one. Any number of permanent magnets 192 of two or more can be used, and the plurality of permanent magnets 192 can be moved between the first position and the second position by a single magnet moving mechanism 194. It is.

  The portable marking device 100 according to the present embodiment is configured to include a cover 193 that covers the permanent magnet 192. If there is no possibility that iron powder or other magnetic metal powder adheres to the permanent magnet 192, the cover is provided. It is also possible to remove 193.

  Moreover, although the portable marking device 100 according to the present embodiment is configured to include the heat-resistant plate 210, when the steel 1600 is at room temperature, the heat-resistant plate 210 is removed and the portable marking device 100 It is also possible to reduce the weight.

  Further, in the portable marking device 100 according to the present embodiment, the compressed air tank 150 is used as the compressed air source. However, instead of the compressed air tank 150, compressed air is generated using a small compressor. It is also possible.

  Moreover, although the magnet moving mechanism 194 in the portable marking device 100 according to the present embodiment is configured to have the spiral spring 197, it is not always necessary to use the spiral spring 197, and the spiral spring 197 is used. Alternatively, the magnet moving mechanism 194 may be configured. In this case, the operator manually moves the trigger lever 196 in the direction of the arrow 1704 or the direction of the arrow 1705 to move the permanent magnet 192 to the first position or the second position.

  In the portable marking device 100 according to the present embodiment, the nozzle 110 is configured to mark the steel 1600 with a symbol in a continuous one-stroke type according to an instruction by a transmission signal transmitted from the control device 160. However, the nozzle 110 may be configured to mark the steel 1600 with a dot matrix type format. The “dot matrix type” refers to a format in which a plurality of dots (circular dots) are continuously marked along the shape of the symbol marked by the nozzle 110 to thereby write the symbol.

  In addition, the portable marking device 100 according to the present embodiment is configured to include the paint tank 140, the compressed air tank 150, and the battery 170 as a power source, but if necessary, the paint tank 140, the compressed air The portable marking device 100 can also be configured with the tank 150 and the battery 170 omitted. In this case, as in a sixth embodiment (FIG. 21) described later, the paint tank 140, the compressed air tank 150, and the battery 170 are prepared separately from the portable marking device 100.

  Furthermore, the housing attachment means 190 is not limited to the configuration in the present embodiment, and various modifications can be made. Below, the modification of this embodiment which changed the structure of the housing attachment means 190 is shown.

And a vacuum pump 252 that sucks air in the space 251 between the adsorbing rubber 250 and the object, and a switch 253 that turns the vacuum pump 252 on or off.

  When the adsorption rubber 250 is pressed against the object (it is not necessary to press it) and the switch 253 is turned on, the vacuum pump 252 starts to operate, and the air is released from the internal space 251 existing between the object and the adsorption rubber 250. Aspirate. Thereby, the adsorption rubber 250 is crushed and the adsorption rubber 250 is adsorbed to the object.

  When the adsorption rubber 250 is adsorbed to the object, the portable marking device 100 can be adsorbed to the object.

  When the portable marking device 100 is removed from the object, the switch 253 is turned off, and then a part of the adsorption rubber 250 is lifted to introduce outside air into the internal space 251, so that the adsorption rubber 250 and thus the portable marking are removed. Device 100 can be removed from the object.

  According to this modification, as in the third modification, the portable marking device 100 can be used for an object that does not have magnetism (for example, glass, stone, wood, ceramics, etc.). Become.

  Furthermore, since the vacuum pump 252 is used in the present modification, it is possible to obtain a suction force stronger than the suction force obtained by the suction rubber 240 used in the third modification.

(Second embodiment)
FIG. 14 is a perspective view when the portable marking device 200 according to the second embodiment of the present invention is viewed from the front, and FIG. 15 is a portable marking device 200 according to the second embodiment of the present invention. It is a perspective view at the time of seeing from the back.

  As shown in FIG. 14, the portable marking device 200 according to this embodiment includes two permanent magnets 201 attached to the front surface of the housing 180 as housing attachment means.

  Each permanent magnet 201 is attached at intervals in the horizontal direction, and is attached at a position higher than half of the total height of the portable marking device 200.

  Further, as shown in FIG. 15, the portable marking device 200 according to the present embodiment is provided with two detaching levers 202 for detaching the permanent magnet 201 from the steel 1600 on the back surface of the housing 180.

  Each detaching lever 202 is attached to substantially the rear of each permanent magnet 201.

  Each detaching lever 202 includes a first portion 202A extending from the back surface of the housing 180 in a direction (horizontal direction) orthogonal to the back surface, and a second portion 202B extending downward from the tip of the first portion 202A. It has a letter shape.

  The portable marking device 200 according to the present embodiment is attached to the steel 1600 via a pair of permanent magnets 201.

  When the portable marking device 200 is detached from the steel 1600, the portable marking device 200 is held with the second portion 202B of the removal lever and the entire portable marking device 200 is tilted upward with the permanent magnet 201 as a fulcrum. The device 200 is removed.

  Even if the portable marking device 200 is pulled in the horizontal direction, it is difficult to remove the permanent magnet 201 from the steel 1600. However, by easily tilting the portable marking device 200 around the permanent magnet 201 as a fulcrum, the permanent marking can be easily made. The magnet 201 can be removed from the steel 1600.

(Third embodiment)
FIG. 16 is a perspective view of the internal mechanism (with the housing 180 removed) of the portable marking device 220 according to the third embodiment of the present invention as viewed from above, and FIG. It is a perspective view at the time of seeing the internal mechanism of the portable marking device 220 concerning a third embodiment from the front side.

  As shown in FIGS. 16 and 17, impact cushioning materials 227 are attached to the four corners of the two support plates 181 </ b> A and 181 </ b> B via support fittings 226. The housing 180 is attached to the support plates 181A and 181B via the shock absorbing material 227, respectively. That is, the internal mechanism of the portable marking device 220 according to the present embodiment is connected to the housing 180 via the shock absorbing material 227.

  The shock absorbing material 227 is made of a material that absorbs shock. For example, the shock absorbing material 227 is made of rubber, soft resin, gel, or the like.

  When carrying the portable marking device 220, there is no risk of dropping it onto the ground. Even if the portable marking device 220 is dropped on the ground, the impact received by the housing 180 when it is dropped is absorbed by the shock absorbing material 227, so that the impact is not transmitted to the internal mechanism of the portable marking device 220.

  As described above, according to the portable marking device 220 according to the present embodiment, even if the portable marking device 220 is dropped on the ground, the internal mechanism of the portable marking device 220 can be protected from an impact at the time of dropping. .

(Fourth embodiment)
For example, as shown in FIG. 2 or FIG. 15, the housing 180 is provided with a storage box 182 that can be freely opened and closed, and a paint tank 140 that supplies paint to the nozzle 110 is stored inside the storage box 182. Yes.

  The paint tank 140 includes a first pouch bag 510 and a second pouch bag 520.

  FIG. 18 is a plan view of the first pouch bag 510.

  The first pouch bag 510 has a hollow bag shape in which a valve 511 is sandwiched between two identical rectangular aluminum sheets (or sheets made of an elastic material), and the outer periphery of the aluminum sheet is bonded by thermocompression bonding. I am doing. That is, the first pouch bag 510 has one opening (no reference symbol), and has a structure in which a valve 511 is attached to this opening. The inside and the outside of the first pouch bag 510 communicate with each other via a valve 511.

  The valve 511 can be closed, for example, by fitting a cap (not shown). That is, the valve 511 can be freely opened and closed, and FIG. 18 shows a state where no cap is attached.

  Since the first pouch bag 510 has a bag-like shape, if a liquid material is injected into the first pouch bag 510, the entire first pouch bag 510 expands, and further, the liquid material. The first pouch bag 510 contracts when the bag is extracted.

  As will be described later, the first pouch bag 510 is filled with paint.

  The second pouch bag 520 is the same size as the first pouch bag 510 and has the same structure.

  The inside of the storage box 182 has a size capable of storing the first pouch bag 510 and the second pouch bag 520 side by side.

  The accommodation box 182 has a first opening 531 and a second opening 532 (see FIG. 3A described later) formed in parallel. The first opening 531 has a size capable of fitting the valve 511 of the first pouch bag 510, and the second opening 532 can fit the valve 511 of the second pouch bag 520. It has a size.

  The first pouch bag 510 is housed inside the housing box 182 with the valve 511 fitted into the first opening 531, and the second pouch bag 520 is fitted with the valve 511 into the second opening 532. Is accommodated in the accommodation box 182. Accordingly, the inside of the first pouch bag 510 communicates with the outside of the storage box 182 through the valve 511, and similarly, the inside of the second pouch bag 520 is connected to the outside of the storage box 182 through the valve 511. Communicate.

  The paint tank 140 having the above structure is used as follows.

  FIGS. 19A to 19C are schematic vertical cross-sectional views showing how the paint tank 140 is used.

  A first pouch bag 510 that is pre-filled with paint is mounted inside the storage box 182. At this time, the valve 511 of the first pouch bag 510 is fitted into the first opening 531 of the storage box 182.

  Nothing is filled in the second pouch bag 520, that is, the second pouch bag 520 is mounted inside the storage box 182 while being empty. At this time, the valve 511 of the second pouch bag 520 is fitted into the second opening 532 of the storage box 182.

  FIG. 19A is a longitudinal sectional view of the inside of the storage box 182 in this state.

  As shown in FIG. 19A, the first pouch bag 510 and the second pouch bag 520 are adjacent to each other (specifically, one aluminum sheet constituting the first pouch bag 510). And the aluminum sheet constituting the second pouch bag 520 are attached to each other in the storage box 182).

  Thereafter, the first hose 541 is connected to the valve 511 of the first pouch bag 510. The first hose 541 is connected to a paint supply destination, for example, a nozzle 110 that sprays the paint. That is, the first pouch bag 510 is connected to the nozzle 110 via the first hose 541.

  Similarly, the second hose 542 is connected to the valve 511 of the second pouch bag 520. The second hose 542 is connected via a pressure reducing valve 543 to a compressor or other high-pressure air source 552 that supplies compressed air. That is, the second pouch bag 520 is connected to the pressure reducing valve 543 and the high pressure air source 552 via the second hose 542.

  The pressure reducing valve 543 reduces the pressure of the high pressure air sent from the high pressure air source 552 to a predetermined pressure, and then sends it to the second pouch bag 520.

  In the initial state, that is, the state shown in FIG. 19A, the first pouch bag 510 is filled with the paint, and therefore the first pouch bag 510 is in an inflated state as a whole.

  Since the second pouch bag 520 is in an empty state, it is pressed by the expanded first pouch bag 510 and is in a contracted state.

  After the first pouch bag 510 and the second pouch bag 520 are mounted in the storage box 182 as described above, high-pressure air is sent from the high-pressure air source 552 to the second pouch bag 520 via the pressure reducing valve 543. To start.

  As the amount of high-pressure air fed from the high-pressure air source 552 into the second pouch bag 520 increases, the second pouch bag 520 starts to inflate.

  Since the storage box 182 is a rigid body, the internal volume of the storage box 182 is unchanged (constant). For this reason, as shown in FIG. 19B, as the second pouch bag 520 is inflated, the first pouch bag 510 is pressed by the second pouch bag 520, and the state shown in FIG. The contraction begins gradually.

  As the first pouch bag 510 contracts, the paint filled in the first pouch bag 510 is pushed out of the first pouch bag 510 through the valve 511. The extruded paint is fed into the nozzle 110 via the first hose 541. The nozzle 110 sprays the paint sent from the first pouch bag 510 onto the steel 1600 that is the object.

  Since the high pressure air continues to be supplied from the high pressure air source 552 to the second pouch bag 520 via the pressure reducing valve 543, the second pouch bag 520 continues to expand. For this reason, the first pouch bag 510 continues to contract, and the paint is continuously fed from the first pouch bag 510 to the nozzle 110 via the first hose 541.

  As shown in FIG. 19C, the second pouch bag 520 continues to expand until it is blocked by the inner wall of the storage box 182 (the inner wall on the left side of FIG. 19C). When the second pouch bag 520 is inflated by the inner wall of the storage box 182, the operation of the high pressure air source 552 is stopped, and the supply of the high pressure air to the second pouch bag 520 is completed.

  At this point, the first pouch bag 510 is maximally shrunk due to the expansion of the second pouch bag 520, and all the paint filled in the first pouch bag 510 passes through the first hose 541. Via the nozzle 110.

  Thereafter, the first hose 541 is removed from the first pouch bag 510, and the second hose 542 is removed from the second pouch bag 520.

  Next, the first pouch bag 510 mounted inside the storage box 182 is taken out.

  The second pouch bag 520 does not need to be taken out and is mounted in the storage box 182 as it is. However, the air inside the second pouch bag 520 is removed beforehand.

  Next, in place of the first pouch bag 510 in which the paint is emptied, a new first pouch bag 510 filled with the paint is mounted inside the storage box 182. Thus, the preparation for supplying the paint to the nozzle 110 for the second time is completed.

  As described above, the following effects can be obtained by using the paint tank 140 in the present embodiment.

  First, it is possible to prevent the paint filled in the first pouch bag 510 from scattering.

  Since the paint is filled in the first pouch bag 510, it does not come into direct contact with the high-pressure air. For this reason, it is possible to prevent scattering of the paint caused by direct contact of the high-pressure air with the paint.

  Second, a certain amount of paint can be supplied to the supplier.

  Since the first pouch bag 510 has a constant volume, it is possible to always supply a fixed amount of paint to the nozzle 551 by supplying the paint to the nozzle 551 using the first pouch bag 510. is there.

  Third, since the first pouch bag 510 filled with the paint can be disposable, it is not necessary to fill the empty first pouch bag 510 with a new paint. The paint can be filled simply by replacing the pouch bag 510 with a new first pouch bag 510.

(Fifth embodiment)

  As shown in FIG. 20, the portable marking unit 300 according to this embodiment includes a portable marking device 100 </ b> A and a portable control unit 310.

  The portable marking device 100A according to this embodiment has the same structure as the portable marking device 100 according to the first embodiment described above, except that the control device 160 is not provided.

  The portable control unit 310 has the same structure and function as the control device 160 in the portable marking device 100 according to the first embodiment.

  In the first embodiment, the control device 160 is incorporated as a component of the portable marking device 100. However, like the portable marking unit 300 according to the present embodiment, the control device 160 corresponds to the control device 160. It is possible to configure the portable control unit 310 to be separate from the portable marking device 100A.

  Thus, by making the portable control unit 310 separate from the portable marking device 100A, for example, one portable control unit 310 is made to correspond to a plurality of portable marking devices 100A. Therefore, the number of portable control units 310 can be reduced. In such a case, for example, as shown in FIG. 20, the portable control unit 310 collectively receives a command signal from the host controller 320, and receives a plurality of portable signals corresponding to the command signal. It can be transmitted to each of the marking devices 100A.
