[Technical Field]

[0001] The present disclosure relates to a measurement device. [Background technology]

[0002] Conventionally, techniques related to measuring devices for measuring the basis weight of sheet-like objects have been known. For example, Patent Document 1 discloses an O-shaped frame having a pair of beams that support a sensor head so that it can move horizontally, and a measuring device that includes the O-shaped frame. The measuring device can easily and inexpensively obtain beams that satisfy shape accuracy and rigidity requirements. One example of the measuring device is an online thickness gauge.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-124104 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional measuring devices have had to be manufactured with clear specifications for each installation location on a production line for producing sheet-like objects. This has led to various problems related to the manufacture of measuring devices, such as not being able to start manufacturing the measuring device until the specifications are clearly defined, short delivery times for measuring devices after the specifications are clearly defined, and large fluctuations in the manufacturing load that reduce the manufacturing efficiency of measuring devices.

[0005] An object of the present disclosure is to provide a measurement device that can be easily manufactured with reduced dependency on specifications for each installation location of the measurement device. [Means for solving the problem]

[0006] In some embodiments, the measuring device measures parameters of a sheet-like object, and includes a pair of sensor heads that move horizontally while facing each other and spaced apart, scanning the object positioned between them; a support that supports the pair of sensor heads so that they can move horizontally; and an electrical unit that controls the measurement of the parameters using the sensor heads, and the electrical unit can be repositioned to either a first position on one side of the support or a second position on the other side depending on the installation location of the measuring device.

[0007] This reduces dependency on the specifications of each installation location of the measuring device, making it easier to manufacture the measuring device. In the measuring device, the position of the electrical equipment can be changed to either the first position or the second position depending on the installation location of the measuring device, so it is possible to always manufacture the same model of measuring device in the manufacturing of measuring devices. It is possible to manufacture and ship the same model of measuring device, and select the appropriate position from the first position or the second position depending on the installation location in the production factory where the target object is produced, and then arrange the electrical equipment in that position.

[0008] In one embodiment, the electrical component may have a mounting structure for mounting the electrical component to the support body at the first position or the second position, thereby enabling the electrical component to be stably and easily fixed to the support body at the first position or the second position.

[0009] In one embodiment, the support may have a first retraction area and a second retraction area, where the object is not present, on the first position side and the second position side of the support, respectively. This makes it possible to form the components of the measuring device, including the support and the pair of sensor heads, symmetrically. Therefore, as described above, it is possible to always manufacture the same model of measuring device in the manufacturing process without considering whether it is the wrong model or not, and to operate the measuring device symmetrically depending on the installation location on the production line.

[0010] In one embodiment, the pair of sensor heads may use the first retraction area as an origin area when the electrical component is in the first position, and use the second retraction area as an origin area when the electrical component is in the second position. This makes it easy to set both the origin areas of the pair of sensor heads and the electrical component on the rear side, which is the maintenance side of the device, in accordance with conventional practice.

[0011] In one embodiment, the measuring device may include a pair of switches attached to the support body on the first position side and the second position side of the support body, respectively, for switching between the function of defining the origin of the sensor head and the function of restricting the movement of the sensor head depending on the arrangement of the electrical component. This makes it possible to always manufacture the same model of measuring device without considering wrong-hand orientation, and to operate the measuring device symmetrically depending on the installation location on the production line, as described above.

[0012] In one embodiment, the measuring device may further include a cable connecting the pair of sensor heads and the electrical component, the cable having at least a portion disposed outside the support, whereby the cable can be appropriately routed relative to the support in response to movement of the electrical component from one of the first position and the second position to the other.

[0013] In one embodiment, the support may be an O-shaped frame having a pair of beams that respectively support the pair of sensor heads, a first stand that connects the ends of one side of the pair of beams together, and a second stand that connects the ends of the other side of the pair of beams together, thereby improving the robustness of the support.

[0014] In one embodiment of the measuring device, the first position may be a position on one side of the O-shaped frame in the longitudinal direction, and the second position may be a position on the other side of the O-shaped frame in the longitudinal direction, thereby making it possible to arrange, according to convention, the evacuation areas for the electrical component and the pair of sensor heads in a direction perpendicular to the transport direction of the object.

[0015] In one embodiment, the object of the measurement device may include a battery electrode sheet, thereby enabling the measurement device to measure parameters of the battery electrode sheet as a measurement object on a production line that produces battery electrode sheets.

[0016] In one embodiment, the parameters of the measuring device may include a basis weight of the object, thereby enabling the measuring device to measure the basis weight of a sheet-like object on a production line that produces sheet-like objects. [Effects of the Invention]

[0017] According to the present disclosure, it is possible to provide a measurement device that can be easily manufactured with reduced dependency on the specifications of each installation location of the measurement device. [Brief explanation of the drawings]

[0018] [Figure 1] 1 is a schematic diagram illustrating a schematic configuration of a measurement device according to an embodiment of the present disclosure. [Figure 2] 2 is a schematic diagram of the measuring device of FIG. 1 as viewed from the direction in which the object is transported. [Figure 3] FIG. 2 is a schematic diagram showing an example of the layout of a coating line for battery electrode sheets. DETAILED DESCRIPTION OF THE INVENTION

[0019] The background and problems of the prior art will now be described in more detail.

[0020] There is a known technology related to an online thickness gauge that uses radiation such as beta rays and X-rays to measure the basis weight of battery electrode sheets, which are produced by thinly coating a mixture of active material or the like on a metal foil and then drying it. In the battery electrode sheet production process, the positive electrode and negative electrode are each formed on a different production line. For example, the positive electrode is formed by thinly and uniformly coating a slurry on the front surface of aluminum foil, drying it in the next process, and then coating the back surface of the aluminum foil in the same way after drying, and then drying it in the next process.

[0021] Inspections during the coating and drying processes may involve measuring the coating weight (i.e., the coating basis weight), measuring the shape of the coated edge, i.e., the edge, and performing image diagnosis of the dried surface condition. The following mainly describes the measurement of coating basis weight using an online thickness gauge.

[0022] For example, as shown in Patent Document 1, an upper sensor head and a lower sensor head are respectively anchored to the upper and lower beams of an O-shaped frame that constitutes an online thickness gauge. The upper and lower sensor heads move horizontally left and right within the O-shaped frame in synchronization with each other to scan a battery electrode sheet as an object. One of the upper and lower sensor heads has a radiation source that emits radiation such as beta rays and X-rays. The other has a detector that detects radiation emitted from the radiation source and transmitted through the battery electrode sheet. The radiation source and detector face each other during scanning of the battery electrode sheet.

[0023] The online thickness gauge uses a pair of sensor heads, including an upper sensor head and a lower sensor head, to measure the amount of radiation transmitted through a battery electrode sheet, which is an object. The online thickness gauge performs similar measurements in advance on multiple samples with known basis weights and calculates a calibration curve. The online thickness gauge can calculate the basis weight of the object from the relationship between the amount of transmission attenuation and the previously calculated calibration curve.

[0024] Online thickness gages are broadly divided into two types: those with integrated electrical components and those with separate electrical components. The electrical components include a transformer, power supply, and control equipment, and control the measurement of basis weight using a pair of sensor heads. The integrated electrical components type has the electrical components built into the O-frame. The separate electrical components type has the electrical components stored in a separate console, not built into the O-frame, and the pair of sensor heads and the electrical components are connected to each other with a cable.

[0025] In both types, a sensor head retreat area is provided outside the width direction of the sheet-like target. In this retreat area, automatic periodic calibration of the sensor head is performed without the target being present, and maintenance is performed during idle periods. Conventional online thickness gages have an asymmetric footprint relative to the target.

[0026] Figure 3 is a schematic diagram showing an example of the layout of a coating line for battery electrode sheets. In a battery electrode sheet production factory, multiple similar production lines may be installed in parallel. For example, an operator, or worker, must simultaneously manage and operate multiple production lines L1 and L2. Typically, a worker manages two production lines L1 and L2 separated by an aisle.

[0027] The operating terminals of each device, including the online thickness gauge, face the aisle. Each device is installed with its operating surface, i.e., the front of the device, facing the aisle. The battery electrode sheet passes through the inside of each device. For example, the battery electrode sheet passes through device M1, online thickness gauge M2, and device M3 in that order. Although each device is different in size, they are designed so that the space on the operating terminal side of each device is narrow, and the electrical components, which require more space, are located on the opposite side from the operating terminal. Maintenance of each device is performed by accessing each device from a separate work aisle located on the opposite side of the aisle.

[0028] As described above, production line equipment, including online thickness gauges, is designed and manufactured with the operation side as the front side and the equipment maintenance side as the back side. Therefore, it is common for some equipment to have mismatched specifications depending on its installation location on the production line. For example, in Figure 3, such mismatched specifications occur between online thickness gauge M2 installed on one production line L1 and online thickness gauge M2 installed on another production line L2 located across the aisle.

[0029] Therefore, when receiving an order for the manufacture of each device, it was necessary to clarify the specifications for each installation location on the production line before starting manufacture of each device. This caused the following various problems related to the manufacture of measuring devices such as online thickness gauges.

[0030] For example, manufacturing of measuring devices cannot begin until the specifications are clearly defined. If it takes too long to determine the specifications, it is expected that the delivery time for measuring devices after the specifications are clearly defined will be shortened. It is difficult to manufacture measuring devices and keep them in stock before the specifications are clearly defined, which leads to large fluctuations in manufacturing load before and after the specifications are clearly defined. As a result, the manufacturing efficiency of measuring devices decreases.

[0031] In addition, if the specifications differ depending on the installation location, a large number of different parts are required for each specification, and the assembly method also differs, reducing the efficiency of assembly work. If a sudden change in the installation specifications of a measuring device occurs on a production line for producing an object, the measuring device must be improved and a new measuring device must be manufactured to meet the new specifications. This can cause delays in operations related to the production of the object and delays in delivery of the object as a finished product.

[0032] In order to solve the above problems, the present disclosure aims to provide a measurement device that can be easily manufactured with reduced dependency on specifications for each installation location of the measurement device.

[0033] Hereinafter, one embodiment of the present disclosure will be mainly described with reference to the accompanying drawings.

[0034] FIG. 1 is a schematic diagram showing a general configuration of a measuring device 1 according to an embodiment of the present disclosure. FIG. 2 is a schematic diagram of the measuring device 1 of FIG. 1 when viewed from the direction in which an object S is transported. In FIGS. 1 and 2, the scale of each component has been appropriately changed so that the component is large enough to be recognizable. In FIGS. 1 and 2, the right side of the measuring device 1 is defined as a first position P1, and the left side of the measuring device 1 is defined as a second position P2. Hereinafter, "one side" refers to, for example, the right side in FIGS. 1 and 2. "The other side" refers to, for example, the left side in FIGS. 1 and 2. The configuration of the measuring device 1 according to an embodiment will be mainly described with reference to FIGS. 1 and 2.

[0035] The measuring device 1 measures parameters of a sheet-like object S. In the present disclosure, 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, basis weight, thickness, and surface position.

[0036] The measuring device 1 is incorporated into, for example, a production line for producing sheet-like objects S, and measures parameters of the objects S that are continuously manufactured and transported in one direction without stopping the transport of the objects S. The measuring device 1 has a support 10, a pair of sensor heads 20, an electrical component 30, a cable 40, and a pair of switches 50. Although not shown in the drawings, the measuring device 1 according to one embodiment also has an operation panel through which an operator inputs instructions.

[0037] 1 and 2, as an example, the state when the pair of sensor heads 20, the electrical component 30, and the cable 40 are positioned on the first position P1 side is shown by solid lines. In contrast, the state when the pair of sensor heads 20, the electrical component 30, and the cable 40 are positioned on the second position P2 side instead of the first position P1 side is shown by two-dot chain lines.

[0038] The support 10 is configured so that the longitudinal direction is perpendicular to the conveying direction D of the object S. The support 10 is formed symmetrically with respect to the object S. More specifically, the support 10 is formed so as to be vertically and horizontally symmetrical with respect to the object S located at the center of the support 10.

[0039] The support 10 supports the pair of sensor heads 20 so that they can move horizontally. More specifically, the support 10 supports the pair of sensor heads 20 so that they can move horizontally along the longitudinal direction of the support 10. The support 10 has a pair of beams 11 that support the pair of sensor heads 20, respectively. The support 10 has a first stand 12a that connects the ends of one side of the pair of beams 11 to each other. The support 10 has a second stand 12b that connects the ends of the other side of the pair of beams 11 to each other.

[0040] The first stand 12a and the second stand 12b are each a self-supporting support structure and support a beam 11. The first stand 12a is connected to one end of a pair of beams 11 arranged in parallel. The second stand 12b is arranged horizontally spaced apart from the first stand 12a and connected to the other end of the pair of beams 11. The pair of beams 11 are arranged parallel to each other and spaced apart from each other vertically. The pair of beams 11 includes an upper beam 11a arranged on the upper side and a lower beam 11b arranged on the lower side.

[0041] The support 10 is an O-shaped frame having an opening 13 surrounded by an upper beam 11a, a lower beam 11b, a first stand 12a, and a second stand 12b. A first position P1 is a position on one side in the longitudinal direction of the O-shaped frame. A second position P2 is a position on the other side in the longitudinal direction. A sheet-like object S, the parameter of which is to be measured, passes through the opening 13 and is continuously transported in one direction from the front side to the back side of the support 10.

[0042] The support 10 has an O-shaped frame upper surface 14a, a first side surface 14b perpendicular to the conveyance direction D of the object S, and a second side surface 14c perpendicular to the longitudinal direction of the support 10. The support 10 has a first corner C1 where the second side surface 14c located on one side of the support 10, i.e., the right side, intersects with the upper surface 14a. The support 10 has a second corner C2 where the second side surface 14c located on the other side of the support 10, i.e., the left side, intersects with the upper surface 14a.

[0043] The support body 10 has a first retraction region R1 and a second retraction region R2, where the object S is not present, on the first position P1 side and the second position P2 side of the support body 10, respectively. The first retraction region R1 is located on one side of the support body 10 in the longitudinal direction with respect to the object S in the internal space of the O-shaped frame surrounded by the upper beam 11a, the lower beam 11b, the first stand 12a, and the second stand 12b. The second retraction region R2 is located on the other side of the support body 10 in the longitudinal direction with respect to the object S in the internal space. In the first retraction region R1 and the second retraction region R2, the object S does not overlap with the pair of sensor heads 20 in the vertical direction.

[0044] The pair of sensor heads 20 move horizontally while facing each other at a distance, and scan the object S positioned between them. More specifically, the two sensor heads 20 are provided spaced apart in the vertical direction, leaving a space for the area through which the object S passes. Each of the pair of sensor heads 20 is fixed to a moving mechanism (not shown), and is supported via the moving mechanism so as to be horizontally movable relative to the beam 11.

[0045] The pair of sensor heads 20 are moved horizontally along the beam 11 by a movement mechanism. The upper sensor head 20a, which is located on the upper side of the pair of sensor heads 20, is supported by the upper beam 11a via a movement mechanism and moves horizontally along the upper beam 11a by the movement mechanism. The lower sensor head 20b, which is located on the lower side of the pair of sensor heads 20, is supported by the lower beam 11b via a movement mechanism and moves horizontally along the lower beam 11b by the movement mechanism.

[0046] The pair of sensor heads 20 use the first retraction region R1 as their origin region when the electrical component 30 is at the first position P1, and use the second retraction region R2 as their origin region when the electrical component 30 is at the second position P2. That is, the pair of sensor heads 20 use the retraction region on the same side as the arrangement position of the electrical component 30 relative to the support body 10 as their origin region.

[0047] When the first retraction region R1 is defined as the origin region, the pair of sensor heads 20 scan the object S while moving horizontally in the longitudinal direction of the support body 10 on the other side of the support body 10 relative to the first retraction region R1, i.e., the left side region. When the second retraction region R2 is defined as the origin region, the pair of sensor heads 20 scan the object S while moving horizontally in the longitudinal direction of the support body 10 on one side of the support body 10 relative to the second retraction region R2, i.e., the right side region. The origin regions of the pair of sensor heads 20 have the same space with respect to the sheet width of the object S on both sides of the first retraction region R1 and the second retraction region R2.

[0048] One of the upper sensor head 20a and the lower sensor head 20b has a radiation source that emits radiation such as beta rays and X-rays. The other has a detector that detects radiation that is emitted from the radiation source and passes through the object S. The radiation source and the detector face each other while the pair of sensor heads 20 scans the object S. The pair of sensor heads 20 detect parameters of the sheet-like object S using radiation. The pair of sensor heads 20 continuously output detection signals of the acquired parameters to the electrical equipment unit 30 via a cable 40.

[0049] The electrical equipment unit 30 controls the measurement of parameters using the sensor heads 20. The electrical equipment unit 30 integrally includes a transformer, a power supply, control devices such as a PLC (Programmable Logic Controller), a control board, a driver for driving a movement mechanism that moves the pair of sensor heads 20, a measurement calculation unit, and an input / output connection port. The electrical equipment unit 30 is not individually mounted directly on the support body 10 as a housing, but is configured by storing each component in a storage case in the form of a single block, for example, a local box.

[0050] The position of the electrical equipment unit 30 can be changed to either a first position P1 on one side of the support body 10 or a second position P2 on the other side, depending on the installation location of the measuring device 1. The first position P1 and the second position P2 are located on both sides of the support body 10 in the longitudinal direction of the measuring device 1. More specifically, the first position P1 is a position along the second side surface 14c on one side of the longitudinal direction of the support body 10. The second position P2 is a position along the second side surface 14c on the other side of the longitudinal direction of the support body 10. In FIGS. 1 and 2, as an example, the electrical equipment unit 30 is located at the first position P1 on one side of the support body 10. The electrical equipment unit 30 can be moved from the first position P1 to the second position P2, for example, when the installation location of the measuring device 1 is changed and different specifications are required for the placement of the electrical equipment unit 30.

[0051] 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. The mounting structure 31 includes a structure that enables the electrical equipment unit 30 to be attached to and detached from the support body 10 by, for example, screwing, fitting, or engagement. The mounting structure 31 includes a hanger structure 31a that enables the electrical equipment unit 30 as a local box to be easily remounted on and removed from the support body 10. In addition, the mounting structure 31 includes a screw fastening structure 31b that fastens the local box to the side surface of the support body 10 via a fixing bracket that is screwed to the side surface of the local box.

[0052] For example, at the first position P1, the electrical equipment unit 30 is hooked onto a first corner C1 on one side of the support body 10 by a hanger structure 31a, and is fixed to a second side surface 14c on the right side of the support body 10 by a screw structure 31b. When the electrical equipment unit 30 moves from the first position P1 to the second position P2, for example, the electrical equipment unit 30 is hooked onto a second corner C2 on the other side of the support body 10 by the hanger structure 31a, and is fixed to the second side surface 14c on the left side of the support body 10 by the screw structure 31b.

[0053] The electrical equipment unit 30 of the measurement device 1, such as a control device and a driver, controls a movement mechanism that moves the pair of sensor heads 20 to generate power, and uses the power to move each of the pair of sensor heads 20 along the pair of beams 11. The electrical equipment unit 30 moves the upper sensor head 20a and the lower sensor head 20b in synchronization with each other. The electrical equipment unit 30 continuously acquires detection signals of parameters of the object S output from the sensor heads 20 as the sensor heads 20 move along the beams 11 using the movement mechanism.

[0054] The electrical equipment unit 30 of the measurement device 1, for example, a 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 amount of transmission attenuation of radiation through the object S based on the acquired detection signal. The electrical equipment unit 30 performs similar measurements in advance on multiple samples whose parameters are known, and calculates a calibration curve. The electrical equipment unit 30 can calculate the parameters of the object S from the relationship between the amount of transmission attenuation and the previously calculated calibration curve.

[0055] The cable 40 connects the pair of sensor heads 20 and the electrical component section 30 to each other. In addition, the cable 40 also connects the pair of switches 50 and the electrical component section 30 to each other. The cable 40 includes a power line, a signal line, a communication line, etc. At least a portion of the cable 40 is arranged outside the support body 10. For example, a portion of the cable 40 is built into the hollow portion of the O-shaped frame that constitutes the support body 10, and the remaining portion extends from the center of the lower beam 11b to the outside of the O-shaped frame and is arranged to be connected to the electrical component section 30 from the outside.

[0056] The position of the cable 40 outside the O-frame changes as the electrical component 30 moves from the first position P1 to the second position P2. More specifically, when the electrical component 30 is at the first position P1, the cable 40 extends from the center of the lower beam 11b toward one side of the support body 10 to the electrical component 30. On the other hand, when the electrical component 30 moves from the first position P1 to the second position P2, the cable 40 extends from the center of the lower beam 11b toward the other side of the support body 10 to the electrical component 30.

[0057] The cable 40 is pulled out to the outside of the local box serving as the electrical equipment unit 30, and has an appropriate amount of slack so that it can be moved to the opposite side of the O-shaped frame together with the electrical equipment unit 30 without having to change the wiring inside the O-shaped frame or the local box. Once the electrical equipment unit 30 has been turned over and secured to the support body 10 by the mounting structure 31, the cable 40 is appropriately positioned and secured along the O-shaped frame.

[0058] The pair of switches 50 are attached to the support 10 on the first position P1 side and the second position P2 side of the support 10, respectively.

[0059] For example, the pair of switches 50 are attached to both sides of the first position P1 and the second position P2 along the upper beam 11a of the support body 10. The pair of switches 50 are located outside the longitudinal direction of the support body 10 in the first retraction region R1 and the second retraction region R2 relative to the upper sensor head 20a when it is located in the origin region.

[0060] For example, the pair of switches 50 are attached to both sides of the first position P1 and the second position P2 along the lower beam 11b of the support body 10. The pair of switches 50 are located outside the lower sensor head 20b in the longitudinal direction of the support body 10 in the first retraction region R1 and the second retraction region R2, respectively, when the lower sensor head 20b is located in the origin region.

[0061] The switch 50 includes, for example, a limit switch. The pair of switches 50 are controlled by the electrical equipment unit 30 and switch between the functions of defining the origin of the sensor head 20 and restricting the movement of the sensor head 20 according to the arrangement of the electrical equipment unit 30.

[0062] For example, when the electrical component 30 is at the first position P1, the switch 50 attached at the first position P1 along the upper beam 11a defines the origin of the upper sensor head 20a. The switch 50 attached at the second position P2 along the upper beam 11a restricts the movement of the upper sensor head 20a so that it does not move excessively toward the other side of the support body 10. When the electrical component 30 moves from the first position P1 to the second position P2, the functions of the switch 50 attached at the first position P1 along the upper beam 11a and the switch 50 attached at the second position P2 along the upper beam 11a are switched back and forth.

[0063] For example, when the electrical component 30 is at the first position P1, the switch 50 attached at the first position P1 along the lower beam 11b defines the origin of the lower sensor head 20b. The switch 50 attached at the second position P2 along the lower beam 11b restricts the movement of the lower sensor head 20b so that it does not move excessively toward the other side of the support body 10. When the electrical component 30 moves from the first position P1 to the second position P2, the functions of the switch 50 attached at the first position P1 along the lower beam 11b and the switch 50 attached at the second position P2 along the lower beam 11b are switched back and forth.

[0064] In the measuring device 1 described above, the installation location of the local box serving as the electrical equipment unit 30 is generally on the rear side, which is the maintenance side of the device, depending on the installation conditions of the measuring device 1 on the production line. For example, when the measuring device 1 is placed on the production line L1 as the online thickness gauge M2 in FIG. 3, the electrical equipment unit 30 is located on the opposite side of the aisle. In correspondence with FIGS. 1 and 2, the electrical equipment unit 30 is located at a second position P2. For example, when the measuring device 1 is placed on the production line L2 as the online thickness gauge M2 in FIG. 3, the electrical equipment unit 30 is also located on the opposite side of the aisle. In correspondence with FIGS. 1 and 2, the electrical equipment unit 30 is located at a first position P1. However, the installation location of the local box serving as the electrical equipment unit 30 is not limited to the above, and may be determined arbitrarily based on the convenience of the workers on the production line, etc.

[0065] It is customary to set a retreat area for the pair of sensor heads 20 on the equipment maintenance side, and to start scanning of the pair of sensor heads 20 from the retreat area, which serves as an origin area. For example, when the measurement device 1 is placed on the production line L1 as the online thickness gauge M2 in FIG. 3, the retreat area for the pair of sensor heads 20 is located on the opposite side of the aisle. In relation to FIGS. 1 and 2, the retreat area for the pair of sensor heads 20 corresponds to the second retreat area R2. For example, when the measurement device 1 is placed on the production line L2 as the online thickness gauge M2 in FIG. 3, the retreat area for the pair of sensor heads 20 is also located on the opposite side of the aisle. In relation to FIGS. 1 and 2, the retreat area for the pair of sensor heads 20 corresponds to the first retreat area R1.

[0066] However, without being limited to the above, the retraction area of ​​the pair of sensor heads 20 may be determined arbitrarily according to the convenience of the worker in relation to the production line, etc. The origin area may be adjusted to match other devices in the production line by software processing using the electrical equipment unit 30.

[0067] According to the measuring device 1 of the embodiment described above, it is possible to easily manufacture the measuring device 1 with reduced dependency on the specifications of each installation location of the measuring device 1. In the measuring device 1, the position of the electrical equipment unit 30 can be changed to either the first position P1 or the second position P2 depending on the installation location of the measuring device 1, so it is possible to always manufacture the same model of measuring device 1. It is possible to manufacture and ship the same model of measuring device 1, and to select an appropriate position from the first position P1 or the second position P2 and arrange the electrical equipment unit 30 depending on the installation location in the production factory where the target object S is produced.

[0068] Because the local box serving as the electrical equipment unit 30 can be easily moved, the occurrence of major problems such as the inability to install the manufactured measuring device 1 on the production line due to specification errors or misunderstandings about which side is used, as in the prior art, is suppressed. When receiving an order for the manufacture of the measuring device 1, the need to clarify the specifications for each installation location on the production line before starting manufacture of the measuring device 1 is reduced, and it becomes possible to start manufacture of the measuring device 1 before the specifications are clarified. This allows for a leeway in the delivery date of the measuring device 1, improving the productivity of the measuring device 1.

[0069] As described above, by enabling planned production of the measuring device 1, it becomes easy to manufacture and stock measuring devices 1 before the specifications are clearly determined. This reduces fluctuations in the manufacturing load in response to material load. As a result, the manufacturing efficiency of the measuring device 1 improves. For example, even for large orders with a lot size of over 100 units, it becomes possible to demonstrate a lead time advantage over competitors through inventory production.

[0070] With the measuring device 1, there is no need to manufacture a large number of parts with different orientations, and the assembly method is the same, improving the efficiency of assembly work. Assembly errors during the assembly work of the measuring device 1 are also reduced. In addition, even if a sudden change in the installation specifications of the measuring device 1 occurs on the production line for producing the object S, this can be addressed by simply changing the layout of the electrical component 30, etc., on the production line. Therefore, operational delays related to the production of the object S and delivery delays when delivering the object S as a finished product are reduced.

[0071] Since the electrical equipment part 30 has an attachment structure 31 that attaches the electrical equipment part 30 to the support body 10 at the first position P1 or the second position P2, the electrical equipment part 30 can be stably and easily fixed to the support body 10 at the first position P1 or the second position P2.

[0072] The support body 10 has the first retraction area R1 and the second retraction area R2, so that it is possible to form symmetrically the components of the measuring device 1, including the support body 10 and the pair of sensor heads 20. Therefore, as described above, it is possible to always manufacture the same model of measuring device 1 in the manufacture of the measuring device 1 without considering whether it is reversed or not, and to operate the measuring device 1 symmetrically according to the installation location on the production line.

[0073] By using the retreat area of ​​the pair of sensor heads 20 on the same side as the electrical equipment section 30 as the origin area, it becomes easy to set the origin areas of the pair of sensor heads 20 and the electrical equipment section 30 together on the back side, which is the equipment maintenance side, in accordance with convention.

[0074] The pair of switches 50 alternately define the origin and restrict the movement of the sensor head 20 depending on the arrangement of the electrical component 30. This allows the same model of measuring device 1 to be manufactured without consideration of whether it is used in the wrong position, as described above, and allows the measuring device 1 to operate symmetrically depending on the installation location on the production line.

[0075] At least a portion of the cable 40 connecting the pair of sensor heads 20 and the electrical component 30 to each other is disposed outside the support body 10. This allows the cable 40 to be appropriately routed along the support body 10 in response to movement of the electrical component 30 from one of the first position P1 and the second position P2 to the other.

[0076] The support body 10 is an O-shaped frame having a pair of beams 11, a first stand 12a connecting the ends of one side of the pair of beams 11, and a second stand 12b connecting the ends of the other side of the pair of beams 11. This improves the robustness of the support body 10.

[0077] Since the first position P1 is a position on one side of the O-shaped frame in the longitudinal direction and the second position P2 is a position on the other side of the longitudinal direction, it is possible to arrange the evacuation areas for the electrical part 30 and the pair of sensor heads 20 in a direction perpendicular to the transport direction D of the object S, according to convention.

[0078] By including a battery electrode sheet in the target object S, the measuring device 1 can measure parameters by using the battery electrode sheet as a measurement target on a production line that produces battery electrode sheets.

[0079] By including the basis weight of the object S as a parameter, the measuring device 1 can measure the basis weight of the sheet-like object on a production line that produces the sheet-like object.

[0080] The support 10 as an O-shaped frame and the electrical component 30 as a local box are separated from each other in terms of configuration, which allows for separation of their manufacturing processes. This makes it easier to mass-produce the measuring device 1. For example, if electrical equipment, control equipment, communication equipment, etc. were individually mounted inside the hollow O-shaped frame and then wiring, piping, and testing were performed, a bottleneck in production volume would occur during mass production, but the measuring device 1 can prevent such bottlenecks from occurring.

[0081] Configuring the electrical equipment unit 30 as a local box also enables compatibility between multiple electrical equipment units 30. In this case, even if a problem occurs in an electrical equipment unit 30 and a quick recovery is required, recovery can be completed simply by preparing and replacing another unit of the electrical equipment unit 30. In addition, inspecting and managing the replaced unit of the electrical equipment unit 30 makes it easier to identify the problem that caused the problem.

[0082] It will be apparent to those skilled in the art that the present disclosure may be embodied in other specific forms other than the above-described embodiments without departing from the spirit or essential characteristics thereof. Therefore, the foregoing description is illustrative and not limiting. The scope of the disclosure is defined not by the foregoing description but by the appended claims. All modifications within the range of equivalents of any modifications are intended to be embraced therein.

[0083] For example, the shape, size, arrangement, orientation, and number of each of the above-mentioned components are not limited to those shown in the above description and drawings. The shape, size, arrangement, orientation, and number of each component may be configured arbitrarily as long as the function can be realized. The components of the illustrated measuring device 1 are functional concepts, and the specific form of each component is not limited to those shown.

[0084] In the above embodiment, the electrical component part 30 has been described as having the mounting structure 31 for mounting the electrical component part 30 to the support body 10 at the first position P1 or the second position P2, but this is not limited thereto. The electrical component part 30 does not have to have such a mounting structure 31. In this case, the electrical component part 30 may be disposed at a position separated from the support body 10 at the first position P1 or the second position P2.

[0085] In the above embodiment, the support 10 has been described as having a first retreat area R1 and a second retreat area R2 where no target object S is present on the first position P1 side and the second position P2 side, respectively, but is not limited to this. The support 10 may have only one of the first retreat area R1 and the second retreat area R2.

[0086] In the above embodiment, the pair of sensor heads 20 have been described as using the first retraction region R1 as the origin region when the electrical component 30 is at the first position P1 and using the second retraction region R2 as the origin region when the electrical component 30 is at the second position P2, but this is not limiting. The pair of sensor heads 20 may use a retraction region on the opposite side of the position of the electrical component 30 relative to the support body 10 as the origin region. The pair of sensor heads 20 do not need to change the retraction region from one of the first retraction region R1 and the second retraction region R2 to the other in response to movement of the electrical component 30, and may fix the retraction region to either the first retraction region R1 or the second retraction region R2.

[0087] In the above embodiment, the pair of switches 50 are described as switching between the definition of the origin and the function of restricting the movement of the sensor head 20 depending on the arrangement of the electrical component 30. However, this is not limiting. For example, if the retraction areas of the pair of sensor heads 20 are fixed regardless of the movement of the electrical component 30, the pair of switches 50 do not need to switch between the definition of the origin and the function of restricting the movement of the sensor head 20 depending on the arrangement of the electrical component 30.

[0088] In the above embodiment, the measuring device 1 has been described as having the cable 40, but is not limited to this. The measuring device 1 may not have the cable 40, and may instead communicatively connect the pair of sensor heads 20 and the electrical component 30 via, for example, wireless communication. The cable 40 has been described as extending from the center of the lower beam 11b to the outside of the O-shaped frame, but is not limited to this. The cable 40 may extend to the outside of the O-shaped frame from any of the upper beam 11a, the first stand 12a, and the second stand 12b instead of the lower beam 11b.

[0089] In the above embodiment, the support 10 is described as an O-shaped frame, but is not limited to this. The support 10 may be formed of a frame structure, a housing structure, or the like of any shape that allows the pair of sensor heads 20 to move horizontally and scan the target S. Alternatively, the support 10 may be formed of a box structure that covers the entire opening 13, leaving only the area through which the target S passes.

[0090] In the above embodiment, the first position P1 on one side of the support body 10 is described as being a position along the second side surface 14c on one side in the longitudinal direction of the support body 10, but this is not limited thereto. The first position P1 on one side of the support body 10 may be a position along a portion of the first side surface 14b of the support body 10 that is located on one side in the longitudinal direction. The second position P2 on the other side of the support body 10 is described as being a position along the second side surface 14c on the other side in the longitudinal direction of the support body 10, but this is not limited thereto. The second position P2 on the other side of the support body 10 may be a position along a portion of the first side surface 14b of the support body 10 that is located on the other side in the longitudinal direction.

[0091] In the above embodiment, the first position P1 is a position on one side in the longitudinal direction of the O-shaped frame, and the second position P2 is a position on the other side in the longitudinal direction. However, this is not limiting. For example, the first position P1 may be a position on one side in the lateral direction of the O-shaped frame, and the second position P2 may be a position on the other side in the lateral direction.

[0092] In the above embodiment, the target object S is described as including a battery electrode sheet, but is not limited thereto. The target object S may also include any other product that is produced in sheet form on a production line.

[0093] In the above embodiment, the measuring device 1 has been described as including an online thickness gauge placed on a production line, but is not limited to this. The measuring device 1 may also include any other relatively small or medium-sized device that would conventionally be misaligned on a production line. A medium-sized device includes, for example, a device large enough that a single unit constituting the device can be moved by approximately two workers.

[0094] In addition to the description in the above embodiment, the storage case of the electrical equipment unit 30 having a local box structure may be provided with functions according to specifications such as dustproofness, watertightness, and EMC (Electromagnetic Compatibility) by appropriately selecting the functions.

[0095] In addition to the explanation in the above embodiment, when air is used in the support 10 or the like, the electrical equipment unit 30 may also include an air device for controlling the air integrated into the local box. In this case, in the measuring device 1, an air tube for supplying air may be arranged along the support 10 in the same manner as the cable 40.
