[0004] The measuring device is equipped with an electrical equipment section for measuring the controlled object. The electrical equipment section is mounted on a support section. In conventional measuring devices, it is difficult to change the installation position of the electrical equipment section after the measuring device is manufactured, and it is difficult to respond to requests to change the installation position of the electrical equipment section according to the installation location of the measuring device and its surrounding environment.

Figure 2 This is a schematic diagram showing the general structure of the measuring device according to Embodiment 1 of the present invention, and a diagram showing the mounting position of the opposite parts.

[0022] exist Figures 1 to 4 In order to set each component to a recognizable size, the scale of each component is appropriately changed. Figures 1 to 4 In this context, one side of the measuring device 1 is designated as position 1 P1, and the other side of the measuring device 1 is designated as position 2 P2. Furthermore, "one side" refers to one side along the moving direction of the sensor head 20, as described later. Figure 1 and Figure 2 The middle section refers to the side indicated by arrow X. "The other side" refers to the side along the direction of movement of the sensor head 20, as described later. Figure 1 and Figure 2 The middle section represents the side indicated by arrow Y. Furthermore, the "movement direction of sensor head 20" will also be simply referred to as the "movement direction," and the "transportation direction of the object" will also be simply referred to as the "transportation direction." The transport direction is... Figures 1 to 4 The middle part is represented by arrow D.

[0023] The measuring device 1 measures parameters of the sheet-like object S. In this invention, the "measuring device 1" includes, for example, an online thickness gauge. The "object S" includes, for example, a battery electrode sheet. The "parameters" include, for example, basis weight, unit coating amount, thickness, and surface position.

[0024] The measuring device 1 is, for example, assembled on a production line for producing sheet-like objects S, to measure the parameters of the continuously manufactured objects S that are conveyed along the conveying direction without stopping the conveying of the objects S. The measuring device 1 includes a support body 10, a pair of sensor heads 20, an electrical equipment section 30, a counter section 35, a first operating section 36, a second operating section 37, a cable 40, and a pair of switches 50. Although omitted in the drawings, the measuring device 1 also has an operation panel for the operator to input instructions.

[0025] exist Figure 1 In the diagram, a solid line indicates the state where a pair of sensor heads 20, electrical equipment 30, and cables 40 are installed on the first position P1 side. In contrast, a double-dotted line indicates the state where a pair of sensor heads 20, electrical equipment 30, and cables 40 replace the first position P1 side and are located on the second position P2 side. Figure 1 Descriptions of the relative section 35, the first operation section 36, and the second operation section 37 are omitted.

[0026] exist Figure 2In the diagram, solid lines represent the opposite portion 35 and the first operating portion 36 located on the first position P1 side, while dashed lines represent the second operating portion 37 located on the first position P1 side. Conversely, a double-dotted line represents the situation where the opposite portion 35, the first operating portion 36, and the second operating portion 37 replace the first position P1 side and are located on the second position P2 side. Figure 2 The description of electrical equipment section 30 and cable 40 is omitted.

[0027] like Figure 3 As shown, when the electrical equipment section 30 is provided on the first position P1 side, the opposing section 35, the first operation section 36, and the second operation section 37 are provided on the second position P2 side. Figure 4 As shown, when the electrical equipment section 30 is provided on the second position P2 side, the opposing section 35, the first operation section 36 and the second operation section 37 are provided on the first position P1 side.

[0028] The support 10 is configured such that its length direction is orthogonal to the conveying direction D relative to the object S. The support 10 is formed symmetrically with respect to the object S. More specifically, the support 10 is formed to be vertically and horizontally symmetrical with respect to the object S located at the center of the support 10.

[0029] A pair of sensor heads 20 are supported on the support body 10 in a manner that allows them to move horizontally. More specifically, the support body 10 supports the pair of sensor heads 20 so that they can move horizontally along the length of the support body 10. Furthermore, in the following description, the direction perpendicular to both the direction of movement and the vertical direction is defined as the depth direction. One side along the depth direction is designated as the near-front side, and the other side as the inner side. In the measuring device 1, the upstream side along the conveying direction D is the near-front side, and the downstream side is the inner side. Figure 2 In the diagram, the front side of the paper is called the front side, and the inside side of the paper is called the inside side. The support 10 has a pair of beams 11 that support a pair of sensor heads 20 respectively. The support 10 has a first bracket 12a that connects one end of the pair of beams 11 to each other. The support 10 has a second bracket 12b that connects the other end of the pair of beams 11 to each other.

[0030] The first support 12a and the second support 12b are each self-supporting structures that support the beam 11. The first support 12a is connected to one end of a pair of parallel beams 11. The second support 12b is horizontally separated from the first support 12a and is connected to the other end of the pair of beams 11. The pair of beams 11 are vertically separated and parallel. The pair of beams 11 have: an upper beam 11a, which is disposed on the upper side; and a lower beam 11b, which is disposed on the lower side.

[0031] The support 10 is an O-shaped frame with an O-shaped opening 13 surrounded by an upper side beam 11a, a lower side beam 11b, a first support 12a, and a second support 12b. The first position P1 is the position on one side of the O-shaped frame along its length. The second position P2 is the position on the other side along the same length. A sheet-like object S, which is the target of the measurement parameter, passes through the opening 13 and is continuously conveyed in one direction from the near-front side towards the inward side of the support 10.

[0032] The support 10 has: an upper surface 14a of an O-shaped frame; a first side 14b, which is orthogonal to the conveying direction D of the object S; and a second side 14c, which is orthogonal to the length direction of the support 10. The support 10 has a first corner C1 where the second side 14c and the upper surface 14a intersect on one side of the support 10, i.e., the right side. The support 10 has a second corner C2 where the second side 14c and the upper surface 14a intersect on the other side of the support 10, i.e., the left side.

[0033] The support 10 has a first avoidance area R1 and a second avoidance area R2 on the first position P1 side and the second position P2 side, respectively, where the object S is not located. The first avoidance area R1 is located on one side of the length direction of the support 10 relative to the object S within the internal space of the O-shaped frame surrounded by the upper side beam 11a, the lower side beam 11b, the first bracket 12a, and the second bracket 12b. The second avoidance area R2 is located on the other side of the length direction of the support 10 within the same internal space relative to the object S. In the first avoidance area R1 and the second avoidance area R2, the object S does not overlap with the pair of sensor heads 20 in the vertical direction.

[0034] A pair of sensor heads 20 are positioned opposite each other while moving horizontally to scan an object S located between them. More specifically, two sensor heads 20 are arranged vertically, separated by an area through which the object S passes. The pair of sensor heads 20 are each fixed to a moving mechanism (not shown) and supported by the moving mechanism to be able to move horizontally relative to the beam 11.

[0035] A pair of sensor heads 20 are horizontally moved along the beam 11 via a moving mechanism. The upper sensor head 20a, positioned on the upper side of the pair of sensor heads 20, is supported on the upper beam 11a via the moving mechanism and moves horizontally along the upper beam 11a via the moving mechanism. The lower sensor head 20b, positioned on the lower side of the pair of sensor heads 20, is supported on the lower beam 11b via the moving mechanism and moves horizontally along the lower beam 11b via the moving mechanism.

[0036] like Figure 3 As shown, when the electrical equipment section 30 is in the first position P1, the pair of sensor heads 20 set the first avoidance area R1 as the origin area. Figure 4 As shown, when the electrical equipment unit 30 is in the second position P2, the second clearance area R2 is set as the origin area. That is, the clearance area of ​​the pair of sensor heads 20 that is on the same side as the electrical equipment unit 30 relative to the support body 10 is set as the origin area.

[0037] When the first clearance area R1 is set as the origin area, the pair of sensor heads 20 scan the object S while moving horizontally along the length of the support 10 in the area on the left side, which is closer to the support 10 than the first clearance area R1. When the second clearance area R2 is set as the origin area, the pair of sensor heads 20 scan the object S while moving horizontally along the length of the support 10 in the area on the right side, which is closer to the support 10 than the second clearance area R2. The origin areas of the pair of sensor heads 20 are on both sides of the first clearance area R1 and the second clearance area R2, and have a space that is the same as the sheet width relative to the object S.

[0038] One of the upper sensor head 20a and the lower sensor head 20b has a radiation source that radiates X-rays. The other has a detector that detects X-rays radiated from the radiation source and transmitted through the object S. The radiation source and the detector are positioned opposite each other during the scanning of the object S by the pair of sensor heads 20. The pair of sensor heads 20 detect parameters of the sheet-like object S using radiation. The pair of sensor heads 20 continuously outputs the detection signals of the acquired parameters to the electrical equipment unit 30 via cable 40.

[0039] The electrical equipment unit 30 controls the measurement of parameters using the sensor heads 20. The electrical equipment unit 30 integrally includes a transformer, power supply, control equipment such as a PLC (Programmable Logic Controller), a control board, a driver for driving the moving mechanism that moves the pair of sensor heads 20, a measurement and calculation unit, and input / output ports. The various structural components included in the electrical equipment unit 30 are not directly mounted to the support body 10, but are housed in a storage box, such as a local toolbox, forming a single unit.

[0040] The electrical equipment unit 30 can be reconfigured at either a first position P1 on one side or a second position P2 on the other side of the support 10, depending on the installation location of the measuring device 1. The first position P1 and the second position P2 are located on opposite sides of the support 10 along its length. More specifically, the first position P1 is located on the second side 14c of one side along the length of the support 10. The second position P2 is located on the second side 14c of the other side along the length of the support 10. For example, if a different configuration of the electrical equipment unit 30 is required due to a change in the installation location of the measuring device 1, the electrical equipment unit 30 can be moved from the first position P1 to the second position P2.

[0041] The electrical equipment unit 30 has a mounting structure 31 that mounts the electrical equipment unit 30 to the support 10 at either a first position P1 or a second position P2. The mounting structure 31 includes, for example, a structure that allows it to be attached to or detached from the support 10 via screwing, fitting, or snapping. The mounting structure 31 includes a suspension structure 31a that allows the electrical equipment unit 30, which serves as a local toolbox, to be easily replaced and mounted on the support 10. Furthermore, the mounting structure 31 includes a screw fixing structure 31b that is screwed to the side of the support 10 via a fixing metal member that is screwed to the side of the local toolbox.

[0042] For example, in position P1, the electrical equipment unit 30 is hooked onto the first corner C1 on one side of the support body 10 via the suspension structure 31a, and fixed to the second side 14c on the right side of the support body 10 via the screw fixing structure 31b. If the electrical equipment unit 30 moves, for example, from position P1 to position P2, it is hooked onto the second corner C2 on the other side of the support body 10 via the suspension structure 31a, and fixed to the second side 14c on the left side of the support body 10 via the screw fixing structure 31b.

[0043] The electrical equipment unit 30 of the measuring device 1, such as a control device and a driver, controls and generates power to move the pair of sensor heads 20, thereby moving the pair of sensor heads 20 along a pair of beams 11. The electrical equipment unit 30 moves the upper sensor head 20a and the lower sensor head 20b synchronously. The electrical equipment unit 30 continuously acquires detection signals of the parameters of the object S output by the sensor heads 20 as they move along the beams 11 via the moving mechanism.

[0044] The electrical equipment unit 30 of the measuring device 1, such as the measurement calculation unit, uses a pair of sensor heads 20, including an upper sensor head 20a and a lower sensor head 20b, to measure the transmission attenuation of radiation caused by the object S based on the acquired detection signal. The electrical equipment unit 30 performs the same measurement in advance on multiple samples with known parameters and calculates a calibration line. The electrical equipment unit 30 can calculate the parameters of the object S based on the relationship between the transmission attenuation and the pre-calculated calibration line.

[0045] The opposing part 35 is mounted on the support body 10. The opposing part 35 is located opposite the electrical equipment part 30. Specifically, as shown in the figure... Figure 3 As shown, when the electrical equipment section 30 is installed in the first position P1, the opposing section 35 is installed in the second position P2. The opposing section 35 is configured to block the side opening 10b formed on the second side surface 14c of the support body 10 when the electrical equipment section 30 is installed in the first position P1. Figure 4 As shown, when the electrical equipment section 30 is installed in the second position P2, the opposing section 35 is installed in the first position P1. The opposing section 35 is configured to block the side opening 10a formed on the first side surface 14b of the support body 10 when the electrical equipment section 30 is installed in the second position P2.

[0046] Furthermore, the side openings 10a and 10b not blocked by the opposing part 35 are blocked by the electrical equipment part 30. As described above, in the measuring device 1, the frame 2 surrounding the pair of sensor heads 20 is configured to include the support body 10, the electrical equipment part 30, and the opposing part 35.

[0047] The first operating unit 36 ​​and the second operating unit 37 are mounted on the opposite part 35. Figure 5 This is a diagram showing the first operating part and the opposite part of the second operating part installed at the second position, viewed along the depth direction. Figure 6 Viewed from above Figure 5 The diagram shows the opposite part. Figure 7 This is a diagram showing the opposite parts of the first and second operating units installed at the first position, viewed along the depth direction. Figure 8 Viewed from above Figure 7 The diagram shows the opposite part. Figure 9 This is an oblique view of the opposing portion installed at the second position, viewed from the inside of the frame. The opposing portion 35 has: a first surface 35a facing the outside of the frame 2; and a second surface 35b facing the inside of the frame 2.

[0048] The first operating part 36 is configured to protrude outward from the first surface 35a of the opposing part 35 toward the outer side of the frame 2. The first operating part 36 can be operated by pressing it into the first surface 35a.

[0049] The second operating unit 37 is mounted on the second surface 35b. A key 38 can be inserted into the second operating unit 37. The second operating unit 37 can rotate the inserted key 38. Figure 5 As shown, the surface of the second operation unit 37 facing the key 38 (the side facing the key 38) becomes the information display surface 37a. Information related to the operation of the key 38 is displayed on the information display surface 37a. For example, such as... Figure 5 and Figure 7 As shown, information is displayed that establishes a correlation between the rotational position of key 38 and the radiation state (on / off) of X-rays. The information is displayed symmetrically above and below the information display surface 37a.

[0050] The second operating unit 37 can change its mounting position relative to the opposing unit 35. For example... Figure 6 and Figure 8 As shown, a fixing part 37b is formed in the second operating part 37. The fixing part 37b is fixed to the second surface 35b of the opposing part 35 by means of screws 63, thereby installing the second operating part 37 onto the opposing part 35.

[0051] Figure 10 This is a view of the opposing portion from the second side. On the second side 35b of the opposing portion 35, a hole 65 for screwing in the screw 63 is formed along the depth direction from the center of the frame 2 at both a position moving towards the front and a position moving inward. Therefore, regardless of whether the opposing portion 35 is installed in the first position P1 or the second position P2, there is a hole 65 located further inward than the center of the frame 2 in the depth direction. Therefore, by using the hole 65 located further inward than the center of the frame 2 in the depth direction to fix the second operating part 37, as... Figure 6 and Figure 8 As shown, when the opposing part 35 is installed in either the first position P1 or the second position P2, the second operating part 37 can be installed further inward than the center of the frame 2 in the depth direction. Furthermore, the unused hole 65 can be sealed by a locking ring.

[0052] Furthermore, the holes 65 are formed symmetrically vertically, allowing the second operation unit 37 to be mounted in an orientation that differs by 180° from the orientation of its information display surface 37a. More specifically, the orientation of the information display surface 37a relative to the opposing part 35 can be 180° different when the opposing part 35 is mounted in the first position P1 and when the opposing part 35 is mounted in the second position P2, yet this mounting of the second operation unit 37 is still achievable.

[0053] The orientation of the information display surface 37a is changed according to the mounting position of the opposing part 35, thereby also changing the direction in which the key 38 is pulled. For example, when the opposing part 35 is installed in the first position P1 and the second position P2, the direction in which the key 38 is pulled is changed to the forward side by making the information display surface 37a face forward.

[0054] A terminal portion 61 is provided on the inner side of the first operation portion 36 in the second surface 35b of the opposing portion 35. A terminal portion 62 is provided on the inner side of the information display surface 37a of the second operation portion 37. Figure 9 As shown, terminal 61 and terminal 62 are connected by wiring 64. In the measuring device 1, a circuit for supplying power to a pair of sensor heads 20 is formed via terminal 61 and terminal 62 connected by wiring 64. The power supply to the pair of sensor heads 20 is cut off by pressing the first operating part 36 or rotating the key 38 inserted into the second operating part 37, thereby disconnecting the contacts.

[0055] That is, the first operation unit 36 ​​functions as an emergency stop button that stops X-ray radiation by pressing it in. In addition, the operation of the measuring device 1 can be stopped by pressing the first operation unit 36 ​​in.

[0056] Furthermore, the second operation unit 37 rotates the inserted key 38, switching between a state setting that allows X-ray radiation and a state setting that prevents X-ray radiation by varying the rotation angle of the key 38. For example, if the key 38 is removed beforehand with the setting that prevents X-ray radiation, then a state where someone without the key 38 cannot receive X-ray radiation will be in a condition where X-ray radiation is not possible.

[0057] Cable 40 connects a pair of sensor heads 20 and electrical equipment section 30 to each other. Furthermore, cable 40 also connects a pair of switches 50 and electrical equipment section 30 to each other. Cable 40 includes power lines, signal lines, and communication lines. At least a portion of cable 40 is disposed outside the support body 10. For example, cable 40 is configured such that a portion is built into the hollow portion of the O-frame constituting the support body 10, and the remaining portion extends from the center of the lower side beam 11b outwards from the O-frame, connecting externally to the electrical equipment section 30.

[0058] As the electrical equipment section 30 moves from position 1 P1 to position 2 P2, the external configuration of the O-frame changes. More specifically, when the electrical equipment section 30 is in position 1 P1, the cable 40 extends from the center of the lower beam 11b toward the support 10 to the electrical equipment section 30. On the other hand, if the electrical equipment section 30 moves from position 1 P1 to position 2 P2, the cable 40 extends from the center of the lower beam 11b toward the other side of the support 10 to the electrical equipment section 30.

[0059] Cable 40 is led out to the outside of the local toolbox, which serves as the electrical equipment section 30, with appropriate clearance so that it can move along with the electrical equipment section 30 to the opposite side of the O-frame even without altering the wiring inside the O-frame and the local toolbox. If the electrical equipment section 30 is flipped over and fixed to the support 10 by the mounting structure 31, cable 40 is properly positioned and fixed along the O-frame.

[0060] A pair of switches 50 are installed on the support body 10 at the first position P1 side and the second position P2 side, respectively.

[0061] For example, a pair of switches 50 are respectively installed on the first position P1 side and the second position P2 side along the upper beam 11a of the support body 10. The pair of switches 50 are located on the outer side of the support body 10 in the length direction, which is further than the upper sensor head 20a when the first avoidance area R1 and the second avoidance area R2 are in the origin area.

[0062] For example, a pair of switches 50 are respectively installed on the first position P1 side and the second position P2 side along the lower side beam 11b of the support body 10. The pair of switches 50 are located on the outer side of the support body 10 in the length direction of the lower sensor head 20b, which is further away from the first clearance area R1 and the second clearance area R2 than when the lower sensor head 20b is located in the origin area.

[0063] Switch 50 may include, for example, a limit switch. A pair of switches 50 are controlled by electrical equipment unit 30 and switch the definition of the origin of sensor head 20 and the function of limiting the movement of sensor head 20 according to the configuration of electrical equipment unit 30.

[0064] For example, when the electrical equipment unit 30 is in position 1 P1, the switch 50 mounted along the upper beam 11a on the side of position 1 P1 defines the origin of the upper sensor head 20a. The switch 50 mounted along the upper beam 11a on the side of position 2 P2 restricts movement in a manner that prevents the upper sensor head 20a from moving excessively toward the other side of the support 10. If the electrical equipment unit 30 moves from position 1 P1 to position 2 P2, the functions of the switch 50 mounted along the upper beam 11a on the side of position 1 P1 and the switch 50 mounted along the upper beam 11a on the side of position 2 P2 are switched.

[0065] For example, when the electrical equipment section 30 is in position 1 P1, the switch 50 mounted along the lower beam 11b on the side of position 1 P1 defines the origin of the lower sensor head 20b. The switch 50 mounted along the lower beam 11b on the side of position 2 P2 restricts movement in a manner that prevents the lower sensor head 20b from moving excessively toward the other side of the support 10. If the electrical equipment section 30 moves from position 1 P1 to position 2 P2, the functions of the switch 50 mounted along the lower beam 11b on the side of position 1 P1 and the switch 50 mounted along the lower beam 11b on the side of position 2 P2 are switched.

[0066] In the measuring device 1 described above, the installation positions of the electrical equipment section 30 and the opposing section 35 can be changed according to the installation conditions of the measuring device 1 on the production line. For example, when a passageway is provided that allows the operator to pass through only one side or the other side relative to the measuring device 1, it is preferable to install the opposing section 35 of the first operating section 36, which functions as an emergency stop button, on the passageway side, and install the electrical equipment section 30 on the opposite side. Furthermore, it is not limited to the above description, and the installation positions of the electrical equipment section 30 and the opposing section 35 can be arbitrarily determined according to the operator's situation on the production line.

[0067] Maintenance of the measuring device 1 is typically performed from the side where the electrical equipment unit 30 is located. Therefore, the clearance area for the pair of sensor heads 20 can also be set on the side where the electrical equipment unit 30 is located, and this clearance area can be designated as the origin area, from which the scanning of the pair of sensor heads 20 begins. Furthermore, it is not limited to the above description; the clearance area for the pair of sensor heads 20 can be arbitrarily determined by the operator according to the production line conditions. The origin area can be aligned with other devices on the production line by utilizing the software processing of the electrical equipment unit 30.

[0068] According to the measuring device 1 of the above-described embodiment, the mounting positions of the electrical equipment section 30 and the opposing section 35 can be changed to a first position P1 and a second position P2. Furthermore, by operating the first operating section 36, which functions as an emergency stop button, and the key 38, the second operating section 37, which is set to either a state where X-ray radiation can be enabled or a state where X-ray radiation cannot be enabled, can be positioned on the opposing section 35. Thus, the positions of the first operating section 36 and the second operating section 37, along with the opposing section 35, can be changed to the first position P1 and the second position P2.

[0069] The first operating unit 36 ​​is located on the outside of the frame 2, so that X-ray radiation can be stopped immediately by pressing it in an emergency. The second operating unit 37 is located on the inside of the frame 2, thus preventing accidental operation of the second operating unit 37 from stopping X-ray radiation.

[0070] The second operating unit 37 can be installed on the opposing unit 35 in different postures. By changing the posture, it can be installed in either the first position P1 or the second position P2 in a posture that allows the key 38 to be pulled forward. Therefore, regardless of whether the opposing unit 35 is installed in either the first position P1 or the second position P2, the key 38 can be operated to rotate through the opening 13 on the forward side of the measuring device 1.

[0071] On the information display surface 37a of the second operation unit 37, information related to the operation of the key 38 is displayed symmetrically from top to bottom. When the second operation unit 37 is installed in the first position P1, in a posture where the key 38 can be pulled out towards the front, and in the second position P2, the installation posture of the second operation unit 37 is rotated vertically. As described above, since the information display surface 37a of the second operation unit 37 displays information related to the operation of the key 38 symmetrically from top to bottom, even when the posture of the second operation unit 37 is rotated vertically, the information is displayed in a state easily recognizable by the operator of the measuring device 1.

[0072] The second operating part 37 can be installed further inward than the center of the frame 2 in the depth direction, whether the opposing part 35 is positioned at the first position P1 or the second position P2. Sometimes, the second operating part 37 is positioned in the measuring device 1 behind the first side 14b of the first bracket 12a or the first side 14b of the second bracket 12b. In this case, if the second operating part 37 is positioned near the center in the depth direction, the first bracket 12a and the second bracket 12b may become obstructions, making it difficult to insert or remove the key 38. As described above, the second operating part 37 can be installed further inward than the center of the frame 2 in the depth direction, whether the opposing part 35 is positioned at the first position P1 or the second position P2. Therefore, the first bracket 12a and the second bracket 12b will not become obstructions, and the measuring device 1 can be configured to facilitate the insertion or removal of the key 38.

[0073] In the measuring device 1, the electrical equipment unit 30 can be configured to change relative to either the first position P1 or the second position P2 depending on the installation location of the measuring device 1. Therefore, it is possible to always manufacture the same model of the measuring device 1 during its manufacturing process. Since it is possible to manufacture and ship the same model of the measuring device 1, the electrical equipment unit 30 can be configured at an appropriate position between the first position P1 and the second position P2 depending on the installation location of the production plant for the production object S.

[0074] The ease of movement of the local toolbox within the electrical equipment section 30 reduces the likelihood of major malfunctions, such as the inability to install the manufactured measuring device 1 on the production line due to incorrect specifications or non-standard features, as was the case with conventional technologies. Regarding the measuring device 1, the necessity of starting its manufacture after specifying its specifications for each installation location on the production line when accepting a manufacturing order is reduced; manufacturing can begin before specifications are determined. Therefore, the delivery time of the measuring device 1 is extended, improving its productivity.

[0075] The ability to plan and produce the measuring device 1 in the manner described above also facilitates the manufacture of the measuring device 1 before specifications are clearly defined, thus maintaining inventory. This suppresses fluctuations in manufacturing load corresponding to the quantity load. As a result, the manufacturing efficiency of the measuring device 1 is improved. For example, even with large orders exceeding 100 units, the superior delivery time compared to competing companies can be demonstrated through inventory production.

[0076] In measuring device 1, there is no need to manufacture a large number of non-standard parts, and the assembly method is the same, thus improving assembly efficiency. Assembly errors in measuring device 1 are also reduced. Furthermore, even if a sudden change in the specifications of measuring device 1 occurs on the production line for the object S, it can be addressed simply by changing the configuration of the electrical equipment section 30, etc., on the production line. Therefore, operational delays related to the production of object S and delivery delays when object S is delivered as a finished product are reduced.

[0077] The electrical equipment unit 30 has a mounting structure 31 that mounts the electrical equipment unit 30 to the support body 10 at the first position P1 or the second position P2, thereby enabling the electrical equipment unit 30 to be stably and easily fixed to the support body 10 at the first position P1 or the second position P2.

[0078] The support 10 has a first clearance area R1 and a second clearance area R2, thereby enabling the symmetrical formation of the structure of the measuring device 1, which includes the support 10 and a pair of sensor heads 20. Therefore, as described above, it is possible to manufacture the measuring device 1 with the same model in the manufacturing process, regardless of non-standard features, and to make the measuring device 1 perform operations symmetrically according to the location of the production line.

[0079] The pair of sensor heads 20 have their origin area set on the same side as the electrical equipment section 30, so that the origin area of ​​the pair of sensor heads 20 and the electrical equipment section 30 can be set on the maintenance side, i.e. the inner side, in accordance with convention.

[0080] A pair of switches 50 switch each other according to the configuration of the electrical equipment section 30, defining the origin and limiting the movement of the sensor head 20. Thus, as described above, it is possible to manufacture the same model of the measuring device 1 in the production of the measuring device 1 without considering non-standards, and to make the measuring device 1 perform operations symmetrically according to the location of the production line.

[0081] At least a portion of the cable 40 connecting the pair of sensor heads 20 and the electrical equipment section 30 is disposed outside the support body 10. Thus, the cable 40 can be properly positioned along the support body 10 in accordance with the movement of the electrical equipment section 30 from one of the first position P1 and the second position P2 to the other.

[0082] The support 10 is an O-shaped frame having: a pair of beams 11; a first bracket 12a that connects one end of the pair of beams 11 to each other; and a second bracket 12b that connects the other end of the pair of beams 11 to each other. This improves the stability of the support 10.

[0083] Position 1 P1 is the position on one side of the O-frame along its length, and position 2 P2 is the position on the other side of the same length, thereby enabling the electrical equipment section 30 and the pair of sensor heads 20 to be arranged in a direction orthogonal to the transport direction D of the object S, as is customary.

[0084] The object S includes a battery electrode sheet, so the measuring device 1 can measure parameters by setting the battery electrode sheet as the object of measurement on the production line that produces battery electrode sheets.

[0085] The parameters include the basis weight of the object S, so that the measuring device 1 can measure the basis weight of the sheet-like object on the production line that produces the sheet-like object.

[0086] The O-frame support 10 and the electrical equipment section 30, which serves as a local toolbox, are structurally separated, thereby enabling the separation of the aforementioned manufacturing processes. This facilitates the handling of mass production of the measuring device 1. For example, if electrical equipment, control equipment, and communication equipment are separately installed within the hollow space of the O-frame for wiring, piping configuration, and testing, a bottleneck in production volume can occur during mass production; however, the measuring device 1 can suppress the occurrence of this bottleneck.

[0087] The electrical equipment unit 30 is configured as a local toolbox, thus enabling interchangeability among multiple electrical equipment units 30. In this case, for example, even if a fault occurs in the electrical equipment unit 30 and prompt repair is required, the repair can be completed simply by preparing and replacing units from other electrical equipment units 30. Furthermore, by inspecting and managing the replaced units of the electrical equipment unit 30, it is easy to identify the cause of the fault.

[0088] Those skilled in the art will understand that the present invention can be implemented in other prescribed ways besides the embodiments described above without departing from its spirit or essential characteristics. Therefore, the preceding description is illustrative but not limiting. The scope of the invention is not defined by the preceding description but by the additional technical solutions. Several modifications falling within its equivalent scope are also included.

[0089] For example, the shape, size, arrangement, orientation, and number of the above-described structural parts are not limited to the illustrations in the above description and figures.

The pair of sensor heads 20 may also set the clearance area on the opposite side of the arrangement position of the electrical equipment unit 30 relative to the support body 10 as the origin area. The pair of sensor heads 20 may not change the clearance area from one of the first clearance area R1 and the second clearance area R2 to the other according to the movement of the electrical equipment unit 30, or the clearance area may be fixed to either the first clearance area R1 or the second clearance area R2.

[0093] In the above embodiment, the function of a pair of switches 50 switching the definition of their origins and restricting the movement of the sensor heads 20 according to the configuration of the electrical equipment unit 30 is described, but it is not limited to this. For example, when the avoidance area of ​​the pair of sensor heads 20 is fixed regardless of the movement of the electrical equipment unit 30, the pair of switches 50 may switch the definition of their origins and restrict the movement of the sensor heads 20 without switching them according to the configuration of the electrical equipment unit 30.

[0094] In the above embodiment, it is described that the measuring device 1 has a cable 40, but it is not limited to this.

It is described that the cable 40 extends from the center of the lower side beam 11b to the outside of the O-frame, but it is not limited to this. The cable 40 may replace the lower side beam 11b and extend to the outside of the O-frame from any of the upper side beam 11a, the first bracket 12a, and the second bracket 12b.

[0095] In the above embodiment, the support 10 is described as an O-shaped frame, but it is not limited to this. The support 10 may also be formed by a frame structure or a box structure of any shape, in which a pair of sensor heads 20 can move horizontally to scan the object S. In addition, the support 10 may be formed by a box structure that completely covers the other parts of the opening 13, leaving only an area for the object S to pass through in the opening 13.

[0096] In the above embodiment, it is stated that the first position P1 on one side of the support 10 is the position of the second side surface 14c on one side of the support 10 along the length direction, but it is not limited to this. The first position P1 on one side of the support 10 can also be the position of the portion of the first side surface 14b of the support 10 along one side of the length direction. Similarly, it is stated that the second position P2 on the other side of the support 10 is the position of the second side surface 14c on the other side of the support 10 along the length direction, but it is not limited to this. The second position P2 on the other side of the support 10 can also be the position of the portion of the first side surface 14b of the support 10 along the other side of the length direction.

[0097] In the above embodiment, it is stated that the first position P1 is the position on one side of the O-frame in the length direction, and the second position P2 is the position on the other side of the length direction, but it is not limited to this.

[0098] In the above embodiments, it is stated that the object S includes battery electrode sheets, but it is not limited to this. The object S may also include any other product manufactured in sheet form on a production line.

[0099] In the above embodiments, it is described that the measuring device 1 includes an online thickness gauge disposed on the production line, but it is not limited thereto. The measuring device 1 may also include any other devices, such as smaller and medium-sized ones, that are currently possible to be non-standard due to the production line. Medium-sized devices, for example, include devices that are about the size of a unit constituting the device that can be moved by about two operators.

[0100] Based on the description of the above embodiments, the storage box of the electrical equipment section 30 with the local toolbox structure can be equipped with functions corresponding to the specifications, such as dustproof, dripproof and EMC (Electromagnetic Compatibility), by appropriately selecting functions.

[0101] Based on the description of the above embodiments, when air is used in the support body 10, the electrical equipment unit 30 may also include air-related instruments for controlling the air in a local toolbox.
