Sorting out defective products. Further, a conventional X-ray foreign object detection device irradiates an object to be transported with X-rays, and detects whether or not foreign objects are mixed in the object to be inspected from the amount of transmitted X-rays. Yes. In addition, the conventional metal detection device generates an alternating magnetic field in the transfer line, passes the object to be inspected in the alternating magnetic field, and whether or not metal is mixed from the detection output when passing through the magnetic field. Is detected.

  In such an article inspection apparatus, a sorting unit such as a sorting apparatus sorts out a non-defective product determined to be OK and a defective product determined to be NG according to the inspection result, so that the non-defective product is transported from a normal production line. Good products are excluded. Then, for example, a predetermined distribution direction corresponding to the inspection result is determined based on the distribution direction information set in advance by associating at least the inspection result representing the defective product with the distribution direction, and for each distribution direction. An example in which the count integration value is displayed side by side with the distribution direction is disclosed in Patent Document 1.

  Embodiments of the present invention will be described below with reference to the drawings.

  The article inspection apparatus according to the present invention is incorporated in a production line (not shown) in which an object to be inspected W such as raw meat, fish, processed food, and pharmaceuticals is conveyed, for example, inspection of foreign matter mixed in the object to be inspected, Alternatively, it is inspected whether or not the weight of the inspection object W is within a specified range.

1. 1st Embodiment (FIGS. 1-4)
In the present embodiment, as shown in FIG. 1, a configuration in which the article inspection device 1 and the sorting device 22 are disposed at predetermined positions on the conveyance path 21 of the inspection object W conveyed by the conveyance conveyor 20 by intermittent feeding. The article inspection apparatus 1 includes an inspection unit 2, a determination unit 3, a general control unit 4, a passage detection sensor 9 as a sorting detection unit, and a display operation unit 5 as a display unit. .

  A sorting device 22 is disposed at a sorting position P6 on the downstream side of the testing position P0 of the inspection unit 2 of the article inspection device 1. Between the inspection position P0 and the selection position P6, there are five stop positions, the stop position P1 and the stop position P5, in order, where the inspection object W stops on the transport path 21 by the intermittent transport of the transport conveyor 20. . The inspection object 2 inspected by the inspection unit 2 moves and stops from the stop position P1 on the transport path 21 to the stop position P5 according to the operation of the transport conveyor 20, and arrives at the sorting position P6 of the sorting device 22. . At the sorting position P6, the sorting device 22 sorts the product into the non-defective product direction or the defective product direction according to the inspection result of the inspection object moved to the sorting position P6.

  The inspection unit 2 outputs inspection data for pass / fail determination based on a detection signal corresponding to the type and size of the foreign matter contained in the inspection object W or a detection signal corresponding to the weight of the inspection object W. ing. The inspection timing at the inspection position P0 of the inspection unit 2 may be whether the inspection object W is moving or stationary. If the inspection object W is moving, the inspection result can be obtained immediately before stopping. It is preferable to carry out at a position close to the stop position where the inspection object W is stationary.

  When the article inspection apparatus 1 is configured as a metal detection apparatus, the inspection unit 2 generates an alternating magnetic field having a predetermined frequency on the inspection object W and inspects from a signal corresponding to a change in the magnetic field due to an object passing through the alternating magnetic field. Data is output. A configuration may be adopted in which the metal contained in the inspection object W is magnetized by a magnetizer such as a magnet and the residual magnetism of the magnetized metal is detected by a magnetic sensor.

  The inspection unit 2 in the case where the article inspection apparatus 1 is configured as an X-ray foreign matter detection apparatus is composed of an X-ray generation source and an X-ray detector, and is covered when X-rays are irradiated from the X-ray generation source. An X-ray detector detects X-rays transmitted through the inspection object W, and outputs inspection data from a detection signal corresponding to the transmission amount. The X-ray detector includes, for example, a plurality of photodiodes arranged in a line in a direction orthogonal to the conveyance direction of the inspection object W conveyed by the conveyance conveyor 20, and a scintillator provided on the photodiode. An array of line sensors is used, X-rays transmitted through the object W to be inspected are received by a scintillator and converted into light, and the light is converted into an electrical signal by a photodiode disposed below the inspection data. It is designed to output.

  The inspection unit 2 in the case where the article inspection apparatus 1 is configured as a weight measuring apparatus is a weighing mechanism such as an electromagnetic balance mechanism disposed below the weighing table with a part of the transport path 21 being a weighing table. The load of the inspection object W placed on the weighing table is measured by the configured load sensor. The load sensor may be a scale mechanism that can measure the weight, and may be configured by a scale mechanism such as a differential transformer mechanism or a strain gauge mechanism.

  Based on the inspection data from the inspection unit 2, the determination unit 3 determines whether or not a foreign object is included in the inspection object W or whether the weight of the inspection object W is within a predetermined range. A pass / fail judgment is made and an inspection result (OK or NG) is output.

  The general control unit 4 controls the entire article inspection apparatus 1 and includes a storage unit 6, a control unit 7, and a display control unit 8.

The storage unit 6 stores various programs for the control unit 7 to control the article inspection apparatus 1, and various parameters for the determination unit 3 to perform pass / fail determination on the inspection object W.
In addition, the storage unit 6 sets the stop positions P1 to P5, the inspection position P0, and the selection position P6 where the inspection object is conveyed and stopped stationary by intermittent feeding as the conveyance positions where the inspection results are sequentially temporarily held by intermittent feeding. Information relating to the inspection result is temporarily stored by associating with each other. The temporarily stored information includes the inspection result output by the determination unit 3, the inspection data output by the inspection unit 2 used for the determination (the weight measurement value, the maximum value of the detection signal in the inspection object, and the detection signal are signal-processed) The maximum value in the inspected object), the inspection time (inspection data acquisition time, determination time, etc.), etc., and these are collectively referred to as inspection result data. In addition, statistical basic data for calculating basic statistics (representative values such as average value, maximum value, minimum value, and dispersion, standard deviation, etc.) to be displayed on the display / operation unit 5 and aggregated values of test results It comes to hold.

  The control unit 7 executes a program stored in the storage unit 6 to change parameters of the determination unit 3 and perform various controls on the article inspection apparatus 1. Further, when the inspection result data held in the storage unit 6 is acquired at a timing when the inspection result data is moved from the stop state to the next stop position by the intermittent transfer operation of the transfer conveyor 20, the inspection object W is stopped at the next stop position. As a result, new association is performed, and the association of the transport position with the inspection result data is updated.

  Specifically, as shown in FIG. 2, the inspection result data held in the storage unit 6 is held in a storage area formed by a ring buffer. The ring buffer has a predetermined number of IDs, and the ring buffer is configured to be the first ID after the final ID. Then, the correlation between the inspection result data held in the storage unit 6 and the transport position is updated by moving the pointer of the inspection position P0 with respect to this ID.

  For example, the first ID is 1 and the final ID is 7 in order to have IDs for 7 positions from the inspection position P0 to the sorting position P6. With respect to the ID of the ring buffer, the pointer at the inspection position P0 (outlined arrow) is moved by one in the moving direction of the pointer, and new inspection result data is written at the ID position of the moved pointer. Further, the ID position before the movement remains as inspection result data of the stop position P1, as the object to be inspected has moved from the inspection position P0 to the next stop position P1 by intermittent conveyance. If repeated several times, the inspection result data of the selection position P6 farthest from the inspection position P0 exists at the ID position where the pointer of the inspection position P0 moves next.

  The timing at which the transfer position correspondence is updated is the timing for moving from the stop state to the next stop position, for example, the movement start timing, the timing during the movement after a predetermined distance or a predetermined time from the movement start, the next The movement end timing or the like arriving at the stop position can be used. In addition, if updating is performed using the inspection end timing of the inspection being performed or the inspection after the arrival of the next stop position, new inspection result data is also held in the storage unit 6 simultaneously with the update of the transport position association. Can do.

  Further, the control unit 7 outputs a sorting command to the sorting device so that the sorting device performs the sorting operation based on the inspection result corresponding to the sorting position P6 held in the storage unit 6, and inspected in the sorting direction. The presence / absence of the movement of the object W is determined by the detection status of the passage detection sensor 9 described later. Specifically, a sorting command is output so that the sorting device performs a sorting operation based on the timing of starting movement from the stopped state to the next stop position, and the passage detection sensor 9 is inspected within a predetermined time from that point. It is determined whether or not an object has been detected. If the inspection object is detected, it is determined that the selection is confirmed, and the inspection result corresponding to the selection position P6 is determined to be valid. Is not performed normally, the test result is determined to be invalid. If the test result is determined to be valid, the statistical basic data held in the storage unit 6 is updated.

  Here, the update timing of the correspondence between the inspection result and the transport position held in the storage unit 6 is a timing for moving from the stop state to the next stop position, and the detection timing of the passage detection sensor 9 is the next from the stop state. Therefore, the inspection result corresponding to the selection position P6 for determining the distribution direction is obtained by updating the correspondence after the movement from the stop state to the next stop position is started. The test result is used. That is, the inspection result (corresponding to the stop position P5 and the next update) stored in the ID position five points ahead of the ID position of the pointer of the inspection position P0 in the storage unit 6 immediately before starting the movement to the next stop position. The inspection result corresponding to the sorting position P6 is used.

  Based on the statistical basic data held in the storage unit 6, the display control unit 8 collects, as the original data, only the test results determined to be valid by the control unit 7 as the selection position P6 in the storage unit 6. The display operation unit 5 displays the inspection data obtained from the inspection result data held at the corresponding ID position, the inspection result, and the total value of the inspection result. That is, the inspection data, the inspection result, the total value of the inspection result, and the statistic that are confirmed to be displayed on the display operation unit 5 at the timing when the movement of the inspection object W in the distribution direction is detected by the passage detection sensor 9. Is supposed to be updated.

  When the inspection object moved to the sorting position P6 is sorted by the sorting device 22 into the non-defective product direction or the defective product direction according to the inspection result, the passage detection sensor 9 detects the inspection object in the sorting direction. A non-defective product passage detection sensor 9a that detects the passage of an inspection object that is arranged at a predetermined position in the non-defective product direction and moves in the non-defective product direction, and is not disposed at a predetermined position in the defective product direction. It consists of a defective product passage detection sensor 9b that detects the passage of the inspection object moved in the non-defective direction.

  These passage detection sensors 9 are photoelectric sensors such as a reflection type sensor that detects a detection object based on a reception state of emitted signal light (visible light such as infrared rays and lasers), and a light projection / reception sensor including a light projector and a light receiver. In this embodiment, a retroreflective photoelectric sensor is used that detects the passage of the inspection object by blocking the light coming out of the sensor and returning from the reflector. Although the passage detection sensor 9 is constituted by a photoelectric sensor, it may be a detection sensor that performs non-contact detection or contact detection of another type. Further, although the selection detection unit is the passage detection sensor 9, the image acquired by the imaging unit may be detected by detecting the passage in the non-defective product direction or the defective product direction by image processing.

  The display operation unit 5 is composed of a touch panel that also functions as an input operation function and a display function. As an input operation, an operation for setting the type of the inspection object W to be transported by the transport conveyor 20 or a foreign object of the inspection object W. Various setting operations and instruction operations related to detection and weighing are performed.

  Further, the display operation unit 5 performs various displays such as a set value when the setting operation of the type of the inspection object W is performed, an instruction value when the instruction operation is performed, and various determination results as the display operation. It is like that.

  The display operation unit 5 may be configured such that the input operation function and the display function are independent. In this case, for the input operation function, a plurality of keys, switches, and the like for input operation for setting and instructions are provided. At the same time, a liquid crystal display or the like can be provided for the display function.

  In addition, the display operation unit 5 displays statistics and inspection results including inspection data of the inspected object whose sorting has been confirmed at a timing when the display of the inspection results performed by the display control unit 8 is updated. In the present embodiment, as shown in FIG. 3, the weight measurement value as the inspection data of the inspected object whose sorting has been confirmed, and the weight measurement of the inspected object that has been confirmed so far after the statistics are cleared. The average value and the inspection result (OK or NG) are displayed.

  Here, assuming that the prescribed range of weight is, for example, “100.0 g ± 1.0 g” is determined in advance, as shown in FIG. 3, a reference value 100.0 g, an upper limit value 101. 0 g and a lower limit of 99.0 g are displayed as basic information. In addition, the inspection data of the inspection object that has been sorted and sorted at the sorting position P6 and confirmed to be sorted in the sorting direction is displayed as 100.0, and the inspection data is within the specified range, so the inspection result is displayed as OK. To do. Furthermore, the average value of the inspection data of the inspected objects that have been confirmed so far after the statistics are cleared is displayed as 100.2 g, and the total number of inspection results, the number of selections, the number of OKs, and the number of NGs The inspection result is reflected and displayed on the upper right of the display screen.

  Next, the operation of the article inspection apparatus 1 will be described.

  FIG. 4 shows an outline processing procedure of a control program related to inspection and inspection result display that are executed starting from intermittent feed start. Here, the inspection end timing at which the movement of the inspection object by the intermittent conveyance operation is resumed and the selection operation is performed based on the inspection result to be moved to the selection position P6 held in the storage unit 6, and the next inspection result is output. An example in which the conveyance position association in the storage unit 6 is updated will be described.

  As shown in FIG. 4, the control unit 7 determines whether or not the intermittent transfer operation of the transfer conveyor 20 has resumed movement from a stationary state (step S <b> 1). (If NO in step S1), this determination process is repeated in a short cycle until the movement is resumed from the intermittent transfer stationary state.

  When the movement is resumed from the stationary state of the intermittent conveyance operation, the presence / absence of the inspection result corresponding to the selection position P6 (the ID position corresponding to the selection position P6 after the association of the conveyance position in the storage unit 6 is updated) If there is no inspection result (in the case of NO in step S2), a display is made. The process proceeds to step 7 without updating, and if there is an inspection result, a sorting command is output to the sorting device 22, and the sorting operation by the sorting device 22, that is, the distribution according to the inspection result is executed. (Step S3).

  Next, the control unit 7 determines whether or not the movement of the inspection object in the distribution direction has been detected by the passage detection sensor 9, and if not detected (NO in step S4), the display is not updated. If the process proceeds to step 7 and is detected, the statistical basic data serving as basic data for calculating the statistical quantity stored in the storage unit 6 is updated (step S5). In this statistical basic data, the maximum number, the minimum value, and the integrated value of the inspection data are updated from the inspection data at the ID position from which the OK number, the NG number, the selection number, and the inspection result are obtained from the inspection result of the selection operation. Further, when the dispersion degree is displayed as a statistic, the inspection data is held.

  Next, the display control unit 8 displays the inspection data, the inspection result, the total value of the inspection result displayed on the display operation unit 5 based on the inspection result data and the statistical basic data corresponding to the selection position P6 held by the storage unit 6 and Update the statistics (step S6).

  Next, the determination unit 3 acquires inspection data from the inspection unit 2 at the inspection timing (step S7), and compares the acquired inspection data with a preset reference value to perform pass / fail determination processing (step S8). .

  Next, the control unit 7 updates the pointer at the test position P0 in the test result data storage area stored in the storage unit 6 by moving it by one in the direction of the pointer movement (step S9), and corresponds to the updated pointer. The inspection result determined by the determination unit 3, the inspection data used for the determination at that time, and the inspection time are written in the ID area as the inspection result data (step S10).

  As described above, the article inspection apparatus 1 according to the present embodiment provides each inspection result of the inspection object W with respect to the transport position in the section from the inspection position P0 of the inspection unit 2 to the selection position P6 of the selection apparatus 22. The storage unit 6 that stores the information in association with the transport position and the passage detection sensor 9 that detects that the inspection object W has moved in the sorting direction by the sorting and sorting as the sorting device 22 sorts and sorts. And the association of the transport position with the inspection result held in the storage unit 6 at a predetermined timing is updated, and the inspection result of the inspection object W whose movement in the distribution direction is detected by the passage detection sensor 9 is determined to be valid. And a display unit operation unit 5 for displaying the total value of the inspection results determined to be valid by the control unit 7.

    With this configuration, only the inspection results of the inspected object W in which the movement of the inspected object W that has been sorted and sorted in the sorting direction is tabulated and displayed, so that the correct tabulated result that matches the actual sorting status is displayed. can do.

  Further, the storage unit 6 stores the inspection data corresponding to the inspection result, and the display operation unit 5 collects the statistic obtained by collecting only the inspection data corresponding to the inspection result determined to be valid by the control unit 7 as the original data. It is characterized by displaying.

  With this configuration, statistics that are collected as original data only from the inspection results of the inspected objects that have been detected to be moved in the distribution direction are displayed. The result can be displayed.

  In addition, although this embodiment demonstrated the case where it conveys by intermittent feed, it is the same also when it is the case where it conveys by a belt conveyor. In that case, the stop positions P1 to P5 are held in the storage unit 6 as passing positions of the inspection object conveyed by the belt conveyor. Here, the interval between the stop positions is preferably set shorter than the interval at which the inspection object is carried in, and the inspection position P0 to the sorting position P6 are preferably divided at equal intervals. In addition, the update of the correspondence of the transport position in the storage unit 6 is performed by setting an internal timer for a delay time obtained from the length between the passing positions and the transport speed of the belt conveyor based on the detection timing of the transport to the inspection position by the transport sensor or the like. By using it, even if there is no next object to be inspected, the sorting position is updated in order. Note that the passing position may be eliminated, and the transport position associated with the storage unit 6 may be configured with two inspection positions P0 and sorting position P6.

2. Second Embodiment (FIGS. 5 to 7)
As shown in FIG. 5, the article inspection apparatus according to the present embodiment is a multiple-structure weight measuring apparatus 30 that measures the weight of a capsule filled with a medicine or the like. A plurality of parallel configurations. The transport path 31 of the capsule Wc that is the inspection object W includes an intermittent transport unit 34 that transports the capsule Wc intermittently for each row, and measures the weight of the capsule Wc disposed on the transport path 31 to measure the weight of the capsule Wc. An inspection unit 32 that outputs weight as inspection data, a sorting unit 50 as a sorting device, and a passage detection sensor 59 as a sorting detection unit are provided. The configuration of the first embodiment is that a weight measuring device 30 as an article inspection device includes a transport path 31 and a sorting unit 50, a passage detection sensor 59 is a non-defective product passage detection sensor 59a, a first defective product passage detection sensor 59b, and The second defective product passage detection sensor 59c is different, and the structure of this one-line conveyance path is different, and a processing unit (determining unit 3) (not shown) that processes inspection data from the inspection unit 32. The general control unit 4, the display operation unit 5, the storage unit 6, and the control unit 7) are the same. Therefore, the description of the first embodiment is appropriately incorporated within a consistent range and the description thereof is omitted.

  FIG. 6 shows a row of transport paths 31. The transport path 31 includes a weighing table 33 connected to a weighing mechanism (not shown) which is a main part of the inspection unit 32, a supply unit 40 for carrying the capsule Wc into the weighing table 33, and a weight measurement by the weighing table 33. The capsule Wc is unloaded and is substantially constituted by an intermittent transport unit 34 that transports the capsule Wc by intermittent transport to the distribution unit 50 that distributes the capsule Wc to a subsequent discharge destination. The inspection unit 32 measures the weight of the capsule Wc placed on the weighing platform 33 with a measuring mechanism, and outputs the measured weight as inspection data.

  The supply unit 40 includes a magazine 41 as a transport path 31, a stopper 42, a pusher 43, a curved recess 44 and a transport groove 45 that constitute a part of the transport path 31. The magazine 41 drops the capsule Wc in accordance with the periodic vertical reciprocation, and when the magazine 41 moves upward from the lower end position, the stopper 42 closes the supply path at the lower end of the magazine 41, thereby Capsules Wc are supplied one by one. Then, the capsule Wc that is obliquely received in the curved recess 44 moves to the conveying groove 45 while changing the axial direction of the capsule Wc by the sliding pusher 43, and sends the capsule Wc to the weighing table 33. The conveyance groove portion 45 is a groove having a V-shaped cross section perpendicular to the conveyance direction, and a slit is formed at the lowermost end of the V shape so that the pusher 43 can slide.

  The weighing platform 33 is formed with a V-shaped groove in the same manner as the conveying groove 45 described above, and can continuously carry the capsule Wc from the conveying groove 45. The capsules Wc sent out from the conveying groove 45 are placed one by one on the weighing table 33, and the weight is measured one by one.

  The intermittent transport unit 34 has a function of intermittently transporting the capsule Wc in synchronization with the operations of the supply unit 40 and the inspection unit 32 described above. The intermittent transport section 34 includes a claw-shaped transport body 35 and a step-shaped transport mechanism 36 as transport means for the capsule Wc.

  The transport body 35 has, for example, a claw-like structure having an E-shaped downward space, holds the capsule Wc of the weighing platform 33 from above, and sends it to the next-stage step-shaped transport mechanism 36. The transport body 35 moves up after transporting the capsule Wc and returns to the initial position in the transport direction deviating from the transport path of the capsule Wc. By repeating this circulation operation, the capsule Wc can be conveyed intermittently in synchronization with the movement of the supply unit 40.
