Description

  The present invention relates to a measuring device.

  In the business of handling courier packages, the person in charge measures the dimensions of the package using the measure, and measures the vertical, horizontal, and height dimensions, and further measures the weight using a platform scale, and uses the conversion table from these data. Thus, the package size and the fee for each destination are calculated.

  Therefore, the shape of the luggage can be measured also by measuring the shape and dimensions by hand.

  However, depending on the manual measurement, there may be individual differences in the person in charge of measuring the baggage, the sizing criteria for irregular packages other than the box type may vary, and the measurement of the size may be neglected during busy periods. Problems such as being unable to determine an appropriate fee will occur.

  In addition, depending on the manual measurement, the data such as the size and the delivery destination is not accumulated as the data of the handled baggage, so that the measured data is wasted.

  Various techniques related to such a background are known (see, for example, Patent Document 1).

  For example, Patent Document 1 describes a luggage shape measuring device used for measuring the size of a courier cargo. More specifically, this load shape measuring apparatus measures the projected area of the load to be measured. The luggage shape measuring apparatus measures the height of the luggage to be measured. Then, the luggage shape measuring apparatus calculates vertical, horizontal, and height data of the measured luggage from the measured height and the projected area. The luggage shape measuring apparatus measures the weight of the luggage to be measured. The package shape measuring apparatus calculates the charge of the delivery destination of the package to be measured from the measured weight and the calculated data. The package shape measuring apparatus transmits the calculation result to the host processing system. In this way, depending on the package shape measuring device, it is possible to unify the standard of receiving charges that have been mixed up to now, and to collect and manage the measurement data of the package that has been wasted. The package size can be measured by simple operation.

  Also, when transporting parcels such as parcel delivery, when receiving parcels from the shipper, determine how large a truck is required to carry the collected parcels together and how much the transportation fee will be charged. In order to do this, it is necessary to measure the weight of each piece and the vertical, horizontal and height dimensions of the piece.

  As a technology for measuring the vertical, horizontal, and height dimensions of this type of luggage, the light emitting / receiving elements are arranged in a straight line in the vertical, horizontal, and height directions, and the rectangular parallelepiped is placed on the weighing conveyor along the positioning guide member. There are devices that can perform these measurements at the same time by loading the package.

  However, delivery packages are also accepted at convenience stores, and the above devices are often operated by people who are not familiar with operations such as part-time jobs. Such a person may not correctly position the load when measuring the weight and size of the load, and may not be able to accurately measure the weight and size of the load.

  As a technique that does not require the positioning operation as described above, there is an apparatus in which a television camera is installed and the height, width, and dimensions of a load are obtained by image processing.

  However, some of the above devices may not be able to measure depending on the color of the baggage, and in order to enable image processing, it is necessary to provide an advanced arithmetic device and a TV camera, which is expensive. There is also a problem of becoming.

  Various techniques relating to such a background are known (see, for example, Patent Document 2).

  For example, Patent Document 2 describes a weight dimension measuring apparatus that measures the weight and dimension of a package such as a rectangular parallelepiped delivery. More specifically, the weight dimension measuring device includes a measuring unit that measures the weight of the load placed in a mounting table shape. The weight dimension measuring device also includes a height sensor that measures the height dimension of the load placed on the placing table. In addition, the weight dimension measuring device includes a bottom surface sensor unit that measures the dimension of the bottom surface of the luggage disposed on the mounting table. The bottom sensor portion is composed of a membrane switch sheet having a large number of contacts arranged in a matrix, and the top surface of the membrane switch sheet is covered with a flexible material having a predetermined thickness. In this way, depending on the weight dimension measuring device, it is possible to accurately measure the weight, the bottom dimension and the height by simply placing a rectangular parallelepiped-shaped baggage to be measured on the mounting table. Even unskilled people can accept luggage and measure its weight and dimensions.

Japanese Patent Laid-Open No. 03-246406 Japanese Patent No. 3460624

  However, the invention described in Patent Document 1 measures the projected area and height of the measured luggage, and calculates the vertical, horizontal, and height data of the measured luggage from the measured projected area and height. It takes time.

  Moreover, since the membrane switch sheet | seat which comprises many contacts arrange | positioned at matrix form is arrange | positioned at the bottom face sensor part, invention of patent document 2 requires many measurement time, and shortens measurement time. I can't.

  The objective of this invention is providing the measuring device which solves the subject mentioned above.

  In order to solve the above-described problem, according to the first embodiment of the present invention, a measuring apparatus, which is provided with a mounting surface on which a measurement object is positioned in a predetermined position, With respect to the first end serving as a reference of the object to be measured in any of the detection direction among the width direction, the length direction, and the height direction of the object to be measured placed on the placement surface, and Is provided with a first detector for detecting a range in which the second end located on the opposite side is located, and movable in the detection direction, and within the range detected by the first detector, And a second detection unit for detecting the position of the second end.

  It should be noted that the above summary of the invention does not enumerate all the necessary features of the present invention. Also, a sub-combination of these feature groups can also be an invention.

  As is clear from the above description, according to the present invention, the dimension of the object to be measured can be measured in a short time.

It is the external appearance perspective view seen from diagonally upward which shows an example of the form of the measuring device 100 which concerns on 1st Embodiment. It is a top view which shows an example of the form of the measuring device 100 which concerns on 1st Embodiment. 3 is a front view of a first fixed sensor 12. FIG. 6 is a plan view for explaining a measurement operation of the measurement apparatus 100. FIG. It is a top view explaining measurement operation of measuring device 300 concerning a 2nd embodiment.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the claimed invention, and all combinations of features described in the embodiments are described below. However, this is not always essential for the solution of the invention.

  FIG.1 and FIG.2 shows an example of the form of the measuring device 100 which concerns on 1st Embodiment. The measuring device 100 is a device that measures the size and weight of the parcel P. The parcel P may be an example of the “measurement object” in the present invention.

  The measurement apparatus 100 includes a mounting table 11, a first fixed sensor 12, a second fixed sensor 13, a third fixed sensor 14, a movement sensor 15, and a control unit 16.

  In measurement by the measuring device 100, in the case of parcel P, in the case of parcel delivery, a charge is set based on the sum of the length dimensions of three sides and the weight. Therefore, the measurement needs to simultaneously acquire the length dimension and weight of the three sides of the parcel P.

  The mounting table 11 is formed in a rectangular block shape and has a mounting surface 18 on which the parcel P is placed. The parcel P has a width dimension L1 in the Y direction, a length dimension L2 in the X direction, and a height dimension L3 in the Z direction.

  The first fixed sensor 12 is disposed along the Y direction near the end of the mounting table 11 in the −X direction, and a plurality of reflection sensor unit sensors disposed along the Y direction along the mounting surface 18. It is constituted by a column S1. The first fixed sensor 12 is electrically connected to the control unit 16. The first fixed sensor 12 detects the width dimension L1 in the Y direction of the parcel P placed on the placement surface 18. The first fixed sensor 12 irradiates the parcel P with detection light in the X direction, and detects the presence of the parcel P by the reflected light that collides with the parcel P and is reflected. The first fixed sensor 12 has a second end N2 located on the side opposite to the first end N1 with respect to the first end N1 serving as a reference of the parcel P in the width direction of the parcel P. The range Q1 to be detected is detected. At this time, the control unit 16 recognizes, as an approximate value, the position of the reflection sensor unit sensor array S1 from which the reflected light has disappeared. The approximate value will be described later. The first fixed sensor 12 may be an example of the “first detection unit” in the present invention.

  The second fixed sensor 13 is arranged near the end portion in the −Y direction of the mounting table 11, and is configured by a plurality of reflection sensor unit sensor rows S <b> 2 arranged along the X direction along the mounting surface 18. The placement surface 18 is disposed near the end in the −Y direction orthogonal to the first fixed sensor 12. The second fixed sensor 13 is electrically connected to the control unit 16. The second fixed sensor 13 detects the length dimension L <b> 2 in the X direction of the parcel P placed on the placement surface 18. The second fixed sensor 13 irradiates the parcel P with detection light in the Y direction, and detects the presence of the parcel P by the reflected light that collides with the parcel P and is reflected. The second fixed sensor 13 has a second end portion N4 located on the opposite side to the first end portion N3 with respect to the first end portion N3 serving as a reference for the parcel P in the length direction of the parcel P. The located range Q2 is detected. At this time, the control unit 16 recognizes, as an approximate value, the position of the reflection sensor unit sensor array S2 where the reflected light has disappeared. The second fixed sensor 13 may be an example of the “first detection unit” or the “second guide member” in the present invention.

  The second fixed sensor 13 protrudes on the placement surface 18 during normal measurement, and is stored below the placement surface 18 during weight measurement. Thereby, the 2nd fixed sensor 13 can form the flat mounting surface 18 which can mount the parcel P stably.

  The third fixed sensor 14 is disposed near the ends of the mounting table 11 in the −Y direction and the −X direction, and a plurality of reflection sensor unit sensor arrays disposed along the Z direction orthogonal to the mounting surface 18. S3 is comprised. The third fixed sensor 14 is electrically connected to the control unit 16. The third fixed sensor 14 detects the height dimension L3 of the parcel P placed on the placement surface 18 in the Z direction. The third fixed sensor 14 irradiates the parcel P with detection light in the Y direction (or may be the X direction), and detects the presence of the parcel P by the reflected light that collides with the parcel P and is reflected. The third fixed sensor 14 has a second end portion N6 located on the opposite side to the first end portion N5 with respect to the first end portion N5 serving as a reference of the parcel P in the height direction of the parcel P. A range Q3 is detected. At this time, the control unit 16 recognizes the position of the reflection sensor unit sensor array S3 from which the reflected light has disappeared as an approximate value. The third fixed sensor 14 may be an example of the “first detection unit” or “first guide member” in the present invention.

  The third fixed sensor 14 is formed in an L shape in a horizontal sectional view, and is rotatably attached to a support base 19 disposed at an end portion of the placement surface 18 in the −X direction and the −Y direction. . The third fixed sensor 14 is rotated between a measurement position A1 orthogonal to the placement surface 18 and a storage position A2 along the placement surface 18 while being supported by the support base 19. The third fixed sensor 14 is folded to the storage position A2 when the measuring device 100 is mounted on a vehicle or held by hand. Thereby, the measuring apparatus 100 is made into a compact outer shape without a protrusion and can be easily carried.

  The movement sensor 15 is a reflection sensor that is electrically connected to the control unit 16, and is attached so as to be movable in the X direction near the end of the mounting table 11 in the −Y direction. The movement sensor 15 is, for example, a combination of a drive source such as a motor (not shown) and a gear reduction mechanism while being supported by a support portion 20 formed in the X direction near the end portion of the mounting surface 18 in the −Y direction. Thus, the entire range in which the parcel P exists is moved in the X direction parallel to the second fixed sensor 13. That is, the movement sensor 15 detects the position of the second end N4 within the range detected by the second fixed sensor 13. At this time, the movement sensor 15 irradiates the parcel P with detection light in the Y direction, and detects the presence of the parcel P by the reflected light that collides with the parcel P and is reflected. The control unit 16 uses the boundary where the reflected light from the movement sensor 15 does not return from the state where the reflected light is returning as a measurement point. Here, until the approximate value measured by the second fixed sensor 13 is approached, the movement sensor 15 is moved at a high speed in the X direction by being set to the high speed mode. Thereafter, the movement sensor 15 is moved at a low speed in the X direction by changing the setting from the high speed mode to the low speed mode when approaching the approximate value measured by the second fixed sensor 13. And the control part 16 calculates the position data by making into a measurement point the boundary where reflected light no longer returns in the movement sensor 15 which is moving in low speed mode. That is, when the second fixed sensor 13 detects the range Q2, the control unit 16 determines that the end point closer to the second end N4 among the end points R3 and R4 on both sides of the range Q2 within the range Q2. After moving the movement sensor 15 to the position corresponding to R4 without performing the detection operation, control is performed to detect the position of the second end N4 within the range Q2. The movement sensor 15 may be an example of the “second detection unit” in the present invention.

  In the mounting table 11, a load cell 22 is internally mounted on a square leg portion 21 on the bottom surface. The load cell 22 is electrically connected to the control unit 16. Therefore, the weight of the parcel P can be measured by the load cell 22. The load cell 22 may be an example of the “measurement element” in the present invention.

  As shown in FIG. 2, the second fixed sensor 13 and the third fixed sensor 14 set the measurement origin M on the placement surface 18. Therefore, the parcel P is brought into contact with the second fixed sensor 13 and the third fixed sensor 14 in the −Y direction and is brought into contact with the third fixed sensor 14 in the −X direction, with the measurement origin M as a reference. Measured.

  The tablet device 17 is wirelessly connected to the control unit 16, and is used by a handy person who decides a fee by hand. Since the charge analysis software is installed in the tablet device 17 in advance, it is automatically determined based on the length information calculated by the control unit 16 and other data such as a destination and a delivery condition inputted in advance. Calculate the fee. The tablet device 17 displays the calculated fee on the display unit 23 and is used by the person in charge to convey the fee to the client of the parcel P.

  The control unit 16 has a built-in calculation unit 24, and uses a general 100V AC power source or a rechargeable battery as a power source. When the parcel P is not detected at a position in the middle of each reflection sensor unit sensor array S1, S2, S3 of each fixed sensor 12, 13, 14, the control unit 16 is in a state where each reflection sensor unit sensor array S1, S2, The size of the parcel P is detected giving priority to the detection of both ends of S3. That is, for example, the control unit 16 has a dent in the parcel P so that the detection light from each of the fixed sensors 12, 13, and 14 does not reflect, or the parcel P is black and from each of the fixed sensors 12, 13, and 14 The dimensions can be detected even when the detection light is not reflected.

  FIG. 3 shows a front view of the first fixed sensor 12. As shown in FIG. 3, the reflection sensor unit sensor row S1 of the first fixed sensor 12 has a position D0, a position D1, a position D2, a position D3, a position D4, a position D5, a position D6, a position D7, a position in the X direction. It is arranged at D8, position D9, and position D10. The positions D0 to D10 have a pitch length L3 of 25 mm, for example, and the position D10 is arranged away from the measurement origin M by a length dimension L4 of 325 mm, for example. Therefore, the calculation unit 24 calculates an approximate value obtained by multiplying the detection position of the reflection sensor unit sensor array S1 of the first fixed sensor 12 by the pitch length L3. Since the other second fixed sensor 13 and the third fixed sensor 14 have the same configuration as the first fixed sensor 12, their description is omitted.

  FIG. 4 is a plan view for explaining the measurement operation of the measurement apparatus 100. As shown in FIG. 4, first, after the measurement device 100 is activated, the parcel P is placed on the placement surface 18 and brought into contact with the fixed sensors 13 and 14. As a result, the parcel P is positioned at a predetermined position with reference to the measurement origin M on the placement surface 18. Then, by driving each of the fixed sensors 12, 13, and 14, the control unit 16 obtains an approximate value of the width dimension L <b> 1 in the Y direction by the first fixed sensor 12, and by the second fixed sensor 13 in the X direction. An approximate value of the length dimension L2 is obtained, and the approximate value of the height dimension L3 in the Z direction is obtained by the third fixed sensor 14. The control unit 16 calculates approximate values in the Y direction, X direction, and Z direction to obtain approximate dimensions.

  At the same time, the movement sensor 15 is moved at high speed in the X direction in the high speed mode until it approaches the approximate value of the length dimension L2 in the X direction measured by the second fixed sensor 13, and then the second fixed sensor 13 At the time C1 when approaching the approximate value of the length dimension L2 in the X direction measured by the above, the mode is changed from the high speed mode to the low speed mode and moved in the X direction at a low speed. Then, the control unit 16 calculates the position data using the boundary point C2 at which the reflected light is no longer returned by the movement sensor 15 moving in the low speed mode as a measurement point, and acquires an accurate measurement value. The movement sensor 15 is also attached in the Y direction and the Z direction, and acquires accurate measurement values of the length dimension L1 in the Y direction and the length dimension L3 in the Z direction.

  Here, as shown in FIG. 1, the second fixed sensor 13 detects the range Q2, and the movement sensor 15 detects the second end of the end points R3 and R4 on both sides of the range Q2 within the range Q2. After moving to the position corresponding to the end point R4 closer to the portion N4 without performing the detection operation, the position of the second end portion N4 is detected within the range Q2. At this time, the calculation unit 24 calculates the position of the second end portion N4 within the range Q2 based on the detection result of the second fixed sensor 13. Specifically, the calculation unit 24 determines the boundary between the range Q2 where the parcel P exists and the range Q4 where the parcel P does not exist based on the detection result of the second fixed sensor 13, and the second fixed sensor 13 before and after the boundary. The size of the parcel P is calculated from the above data. Then, the control unit 16 obtains the weight value measured by the load cell 22.

  That is, the movement sensor 15 is moved at a high speed to a position C1 corresponding to a value close to the approximate value, and when moving closer to the position C1, the movement sensor 15 is switched from the high speed mode to the low speed mode and continues to move. Then, the control unit 16 calculates the measurement value by calculating the position data using the boundary position C2 where the reflected light is no longer returned in the movement sensor 15 as the measurement point. Therefore, the control unit 16 transfers the calculation results of the accurate measurement values of L1, L2, and L3 obtained by the movement sensor 15 and the weight value measured by the load cell 22 to the tablet device 17, and the operator The charge of the parcel P displayed on the display unit 23 of the tablet device 17 is transmitted to the requester of the parcel P.

  As described above, according to the measuring apparatus 100 of the present embodiment, the second fixed sensor 13 is relative to the first end N3 that is the reference of the parcel P in the detection direction in the length direction of the parcel P. The movement sensor 15 detects the position of the second end N4 within the range Q2 detected by the second fixed sensor 13 and detects the range Q2 where the second end N4 located on the opposite side is located. To detect. Therefore, the measuring apparatus 100 can measure the size of the parcel P in a short time.

  Further, according to the measuring apparatus 100, when the second fixed sensor 13 detects the range Q2, the control unit 16 detects the end point R3 of the first end N3 and the second end N4 on both sides of the range Q2. After the movement sensor 15 is moved to the position corresponding to the end point R4 closer to the second end portion N4 among the end points R4 without performing the detection operation, the second end portion N4 is within the range Q2. The control to detect the position of is performed. Therefore, the control unit 16 can perform energy-saving measurement by using the minimum power for sensing.

  Further, according to the measuring apparatus 100, the calculation unit 24 determines the boundary between the range Q2 where the parcel P exists and the range Q4 where the parcel P does not exist based on the detection result of the second fixed sensor 13, and before and after the boundary. The size of the parcel P is calculated from the data of the second fixed sensor 13. Therefore, the calculation unit 24 can calculate the exact size of the parcel P.

  Further, according to the measuring apparatus 100, the parcel P placed on the placement surface 18 is brought into contact with the fixed sensors 13, 14, so that the parcel P can be measured with reference to the measurement origin M on the placement surface 18. It can be positioned at a predetermined position.

  In addition, according to the measuring device 100, by folding the third fixed sensor 14 to the storage position A2, the measuring device 100 can be easily carried with a compact outer shape without any protrusions.

  Further, according to the measuring apparatus 100, the load cell 22 can measure the weight simultaneously with the measurement of the size of the parcel P.

  Further, according to the measuring apparatus 100, when the weight measurement by the load cell 22 is performed, the second fixed sensor 13 is stored in a position where it does not jump out of the placement surface 18, so that the parcel P can be stably placed. The mounting surface 18 can be formed.

  Next, the second embodiment will be described with reference to FIG. 5, but the same parts as those in the first embodiment are denoted by the same reference numerals, the description thereof will be omitted, and only different points will be described. FIG. 5 is a plan view for explaining the measurement operation of the measurement apparatus 300 according to the second embodiment. As shown in FIG. 5, the measuring apparatus 300 includes three first movement sensors 31, second movement sensors 32, and third movement sensors 33. Each of the movement sensors 31, 32, and 33 is a reflection sensor that is electrically connected to the control unit 16, and is mounted side by side with an interval in the X direction near the end of the mounting table 11 in the −Y direction. . Each of the movement sensors 31, 32, and 33 is independently moved in the X direction while being supported by the support portion 20 formed in the X direction near the end portion of the mounting table 11 in the −Y direction. At this time, the 1st movement sensor 31 makes the measurement range from the measurement origin M which is a part of measurement range to the 1st boundary point E1. The second movement sensor 32 has a measurement range from the first boundary point E1 to the second boundary point E2, which is a part of the continuation of the measurement range following the first boundary point E1. The third movement sensor 33 has a measurement range from the second boundary point E2, which is the remaining part of the measurement range following the second boundary point E2, to the third boundary point E3 at the end of the mounting table 11 in the X direction. .

  When the measuring device 300 measures the length L2 of the parcel P in the X direction, the approximate value measured by the second fixed sensor 13 exceeds the measurement range of the first movement sensor 31, and the second When the measurement range of the movement sensor 32 is exceeded, the first movement sensor 31 and the second movement sensor 32 do not move, and only the third movement sensor 33 is moved from the second boundary point E2 in the X direction at a low speed. At this time, the calculation unit 24 determines the size of the parcel P from the data of the movement sensors 31, 32, and 33 and the position data of the movement sensors 31, 32, and 33 having the boundary points E1, E2, and E3 as measurement ranges. calculate. And the control part 16 calculates the measured value by calculating the position data by using the 4th boundary point E4 from which the reflected light stopped returning in the 3rd movement sensor 33 as a measurement point.

  According to the measurement apparatus 300 of the present embodiment, only one of the movement sensors 31, 32, 33 close to the approximate value is moved according to the size of the parcel P, so that the measurement time can be greatly shortened. At the same time, since power is not continuously used, power consumption can be significantly reduced.
