  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 the specified range name.

1. 1st Embodiment (FIGS. 1-4)
In this embodiment, as shown in FIG. 1, the article inspection apparatus 1 and the sorting apparatus 22 are arranged at predetermined positions on the conveyance path 21 of the inspection object W that is intermittently conveyed by the conveyance conveyor 20. The article inspection apparatus 1 includes an inspection unit 2, a determination unit 3, a general control unit 4, 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 of the conveyance conveyor 20 where the inspection object W is stopped on the conveyance path 21 by intermittent conveyance, from the stop position P1 to the stop position P5 in order. The workpiece W inspected by the inspection unit 2 moves from the stop position P1 on the transport path 21 to the stop position P5 according to the operation of the transport conveyor 20, stops, 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 at the sorting position P6.

  The inspection unit 2 outputs 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. The inspection timing at the inspection position P0 of the inspection unit 2 may be whether the inspection object W is moving or stationary, and when it is moving, a position close to a stop position where the inspection object W stops. It is preferable to carry out.

  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 outputs a signal corresponding to a change in the magnetic field due to an object passing through the alternating magnetic field. It is supposed to be. 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. The X-ray detector detects X-rays that have passed through the inspection object W, and outputs 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 line sensor is used, and X-rays transmitted through the object W are received by a scintillator and converted into light, and the light is converted into an electrical signal by a photodiode disposed below the X-ray and output. It has become.

  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 detection signal 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 or not the weight of the inspection object W is within a predetermined range. In addition to performing the pass / fail determination, the inspection result (determination result) is displayed on the display operation unit 5.

  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 correlates with each stop position where the inspection object is intermittently conveyed and stops, the determination result of the determination unit 3 (OK or NG of the inspection result), and the detection signal of the inspection unit used for the determination Inspection data (weight measurement value, maximum value of detection signal in inspection object, maximum value in inspection object that processed detection signal, etc.), inspection time (inspection data acquisition time, determination time, etc.) Etc. are stored as inspection result data.

  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.

  When the display control unit 8 acquires the timing at which the inspection result data stored in the storage unit 6 is moved from the stop state to the next stop position by the intermittent operation of the transport conveyor 20, the inspection object W is stopped next time. A new association is performed as if it were stationary at the position, and the inspection result data corresponding to each stop position is updated.

  Specifically, as shown in FIG. 2, the inspection result data stored in the storage unit 6 is stored in a storage area configured 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 position information of the stored inspection result data 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 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.

  Note that the timing for updating the position information is the timing for moving from the stop state to the next stop position, for example, the movement start timing, the timing during movement for a predetermined distance or a predetermined time from the start of movement, and the next stop position. The movement end timing or the like that arrived at can be used. In addition, if the inspection result data stored in the storage unit 6 is updated using the inspection end timing of the inspection that is moving or after the arrival of the next stop position, the position information is updated and a new inspection is performed at the same time. The result data can also be stored in the storage unit 6.

  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.

  The display operation unit 5 also transfers the inspection result data of each inspection position stored in the storage unit 6 in the order of the conveyance direction at the timing when the display control unit 8 updates the position information to the storage unit and the inspection result. They are displayed side by side. That is, the inspection result of the inspection object stationary at the stop positions P1 to P5 of the downstream conveyor 20 including the inspection position P0 and the inspection result of the inspection object W discharged by the selection device 22 at the selection position P6 are displayed. It has become.

  In this embodiment, as shown in FIG. 3, inspection data corresponding to the inspection result (weight in this example) is displayed as the inspection result under the display of P0 to P6 corresponding to the selection position P6 from the inspection position P0. Furthermore, when the inspection result is OK, the background color of the inspection data is white, and when the inspection result is NG, the background color of the inspection data is set to another color (for example, red) to identify the inspection result of the inspection object. It is displayed as a list. Further, the latest inspection result at the inspection position is enlarged (emphasized) separately from the list display, and the inspection data and the inspection result (OK or NG) are displayed side by side.

  Here, when, for example, “100.0 g + 0.3 g” is predetermined as the prescribed range (threshold value) of the weight, as shown in FIG. 3, the inspection result of the inspection object at the inspection position P0 position is shown. Is 100.0, the inspection result of the inspection object at the stop position P1 and the stop position P5 is 100.1, the inspection result of the inspection object at the stop position P2 position and the stop position P4 is 100.2. Since it falls within the range, the background color of the inspection data indicating that the inspection result is OK is white.

  Further, the inspection result of the inspection object at the stop position P3 is 100.5, and the inspection result of the inspection object is 100.4 at the selection position P6, which is outside the specified range. The background color of is a color other than white (here, gray).

Further, the latest inspection result displayed separately from the list display is the same value as the inspection result of the inspection object at the inspection position P0, and OK is displayed with a measured value of 100.0 g.
In this embodiment, the inspection data of the inspection position is included in the list, but the inspection result data corresponding to the selection position P6 from the stop position P1 downstream from the inspection position not including the inspection position P0 In addition to the list, the latest inspection result at the inspection position P0 may be displayed. Alternatively, only OK or NG pass / fail judgment results may be displayed as a list.

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

  FIG. 4 shows a schematic processing procedure of a display control program for displaying the inspection result, which is executed by the control unit 7 of the article inspection apparatus 1. Here, the timing at which the position information in the storage unit 6 is updated will be described by taking as an example a case in which the position information is updated by using the inspection end timing at which the inspection is performed and the determination result is output.

  As shown in FIG. 4, the control unit 7 determines whether or not the inspection unit 2 is at the inspection start timing (step S1), and if it is not at the inspection start timing (NO in step S1), the control unit 7 sets the inspection start timing. This determination process is repeated in a short cycle until

  At the inspection start timing, the determination unit 3 acquires a detection signal from the inspection unit 2 (step S2), and compares the inspection data based on the acquired detection signal with a preset reference value to determine whether or not pass / fail. (Step S3).

  Next, the control unit 7 updates the pointer at the inspection position P0 in the storage area of the inspection result data stored in the storage unit 6 by moving it one by one in the direction of the pointer movement (step S4), 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 as inspection result data in the ID area to be processed (step S5).

  Next, the control unit 7 acquires the inspection result data corresponding to the stop position in the transport direction and another position in order from the ID based on the pointer of the inspection position P0 in the storage area of the inspection result data stored in the storage unit 6. The inspection results corresponding to the selection position P6 from the inspection position P0 are identified and displayed as a list (step S6).

  As described above, in the article inspection apparatus 1 according to the present embodiment, the inspection position P0 of the inspection unit 2 and the stop position P0 in a predetermined range downstream from the inspection position P0 where the inspection object W is stopped by the intermittent operation of intermittent conveyance. ... P5 includes a storage unit 6 for storing the inspection result of the inspection object W in association with each position, and the display operation unit 5 can identify the inspection result at each position based on the storage unit 6. The display is performed in the order of positions in the transport direction.

  With such a configuration, the pass / fail judgment result at each stop position downstream from the inspection position is displayed in an identifiable manner. For example, the inspection line is stopped and the inspected inspection object remaining on the transport path is displayed. Since the inspection results are displayed in the order of conveyance in the display operation unit 5 so as to be identifiable, the operator can easily distinguish these inspected items from non-defective products and defective products from above the conveyance path 21 by confirming the display. It can be taken out.

  The storage unit 6 stores inspection data corresponding to the inspection result, and the display operation unit 5 displays the inspection data at each position.

  With such a configuration, inspection data such as weight is displayed corresponding to each stop position P0... P5, so that it is possible to visually confirm on the display screen that the operator is measuring correctly.

  Further, the sorting device 22 is provided in the subsequent stage of the transport conveyor 20, and the storage unit 6 stores the inspection result of the inspection unit 2 and the corresponding inspection data in the sorting position P6 of the sorting device 22 in association with each other as the last stage position, and displays The operation unit 5 displays the inspection data of the inspection object W selected by the selection device 22.

  With this configuration, the measurement value of the inspection object W at the selection position P6 is displayed. Therefore, the inspection object W that has been excluded as a defective product by the selection device 22 is measured with another measurement device. The performance of the article inspection apparatus 1 can also be confirmed.

2. Second Embodiment (FIGS. 5 to 9)
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, which is the inspection object W, measures the weight of the capsule Wc by measuring the weight of the intermittent transport unit 34 that intermittently transports the capsule Wc for each row and the capsule Wc arranged on the transport path 31. It has the inspection part 32 which outputs as a detection signal, and the distribution part 50 as a selection apparatus. The configuration of the first embodiment is that the weight measuring device 30 as an article inspection device includes a transport path 31 and a sorting device 50, and further, the structure of this one-line transport path is different. A processing unit (not shown) (determination unit 3, comprehensive control unit 4, display operation unit 5, storage unit 6, and control unit 7) that processes the inspection data based on the detection signal from the inspection unit 32 is the same, so the first embodiment. The above description will be appropriately incorporated as long as there is no contradiction, and the description thereof will be 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 intermittently transports 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 a detection signal.

  The supply unit 40 includes a magazine 41 as a transport path 31, a stopper 42, a pusher 43, and a curved recess 44 and a transport groove part 45 that constitute a part of the transport path 32.

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 intermittently conveyed in synchronization with the movement of the supply unit 40. The time during which the intermittent conveyance operation is stopped substantially coincides with the weighing timing of the inspection unit 32.

  The stair-like transport mechanism 36 includes a fixed step member 37 configured to be lowered stepwise over the transport direction of the capsule Wc, and a stepped pusher 38 configured to be lowered stepwise similarly to this. Have. In each step portion of the fixed step member 37, the path through which the capsule Wc is conveyed is formed in the same V-groove shape as described above, and further, a pusher slit is formed in the same manner as described above. The stepped pusher 38 is made of an integral plate formed in a step shape substantially the same shape as the fixed step member 37 and is placed in the V-groove of each step of the fixed step member 37 by sliding back and forth in the conveying direction. The capsules Wc being pushed are pushed by the stepped pusher 38 and are sequentially sent to the lower stage, where they are conveyed in a questionable manner. In the intermittent transport section 34, a regulating member 39 is provided above the stepped transport mechanism 36, so that the capsule Wc jumps out of the specified direction while the capsule Wc is transported by the stepped transport mechanism 36. To prevent.

  The sorting unit 50 is provided on the downstream side of the intermittent transport unit 34. When the capsule Wc is transported from the intermittent transport unit 34, the sorting unit 50 switches the transport destination of the capsule Wc based on the determination result from the inspection unit 32. I can. The distribution unit 50 includes a drop port 51 and an opening / closing lid 52, and controls the opening / closing of the opening / closing lid 52 in synchronization with the operation of the intermittent conveyance unit 34, so that the upstream first transport destination A and the downstream side are controlled. The capsules Wc can be selectively dropped on any of the second transport destinations B, and sorting by weight can be performed. In the present embodiment, the first transport destination A is a place for transporting defective capsules Wc, and the second transport destination B is a place for transporting non-defective capsules Wc.

  The inspection unit 32 in the present embodiment is provided for each conveyance path, and the determination unit 3 is also provided for each conveyance path corresponding to the inspection unit 32. The general control unit 4 controls the entire weight measuring device 30, and the storage unit 6 and the control unit 7 perform the same operation as that of the first embodiment for each conveyance path.

Displayed as a list in rows. In each cell of the list, an inspection result at each position of each conveyance path and a weight measurement value as inspection data are displayed. As for the inspection result, when the determination result of the determination unit 3 is OK, the background color of the cell is white, and when the determination result is NG, the background color of the cell is another color such as red (indicated by hatching in FIG. 7). As a result, the inspection results of the capsules Wc are displayed in a list so that they can be identified. Further, a location where the inspection has not been performed due to some reason such as supply failure is left blank to indicate that there is no inspection result.

  In addition, as another display example, as shown in FIG. 8, the display is in the form of a list similar to FIG. 7, but each cell of the list shows that it has been inspected instead of the weight measurement value. The capsule mark is displayed, and the weight measurement value (each individual value) is displayed only in the row of the selection position P6. By doing in this way, an operator can grasp | ascertain the inspection condition of each row | line now more visually, and the comparison of the weight measurement value when checking the weight of the distributed capsule Wc becomes easier.

  Although a plurality of columns are displayed as a list, as shown in FIG. 9, only one column is displayed as in the first embodiment, and a CH switching button for switching the display columns is provided on the display operation unit 5. Each time the CH switching button is pressed, the column may be switched in order.

  As described above, the weight measuring device 30 according to the second embodiment of the present invention is configured by a plurality of parallel transport paths 31, and the display operation unit 5 has a plurality of rows of inspection results corresponding to the plurality of transport paths 31.
