Description

The present invention relates to an inspection system, an inspection method and an inspection program.

For example, Patent Literature 1 proposes a delivery system by tagging containers with traceability information.

JP 2020-135204 A

In the case of packing relatively small manufactured products in a cardboard box for shipment, for example, such a cardboard box has been managed as one unit. In particular, in the case of a manufacturing process in which many manufactured products are conveyed on a conveyor line at high speed, even if each manufactured product is inspected while being conveyed, the inspection results are associated with each manufactured product. difficult to manage. That is, it has been difficult to simultaneously obtain identification information for identifying an individual product and inspect the individual product at the same location on the transfer line. Nonetheless, if the acquisition of identification information and the examination were performed at different times in different places, there was a risk that the identity of the individual could not be guaranteed.

The present invention has been made to solve such problems, and even in the case of a manufacturing process in which many manufactured products are conveyed at high speed on a conveying line and inspected, inspection information can be produced. It provides an inspection system or the like that manages each product and realizes traceability of each manufactured product.

An inspection system according to a first aspect of the present invention includes a reading device that reads identification information given to each of inspection objects that are continuously conveyed along a conveying line, and a reading position where the reading device reads the identification information. An inspection device that inspects the preset inspection items of the inspection target product, the inspection position being set within a range where the inspection target product is not missing and the change in the transportation order does not occur, and the reading position, the inspection position, and the inspection target product a storage control unit that associates inspection information inspected by the inspection device with identification information of the inspection object read by the reading device based on the conveying speed, and stores the inspection information in the storage device. According to the inspection system configured in this manner, the identification information of the inspection target product and the inspection information can be associated with each other, so accurate traceability of the manufactured product, which is the inspection target product, can be achieved.

In the inspection system described above, the inspection apparatus has a plurality of inspection modules each of which performs an inspection of an inspection item assigned in advance, and the storage control unit inspects the inspection items to which each of the plurality of inspection modules is assigned. It is also possible to aggregate the inspection results inspected by each of the plurality of inspection modules and use them as inspection information based on the respective inspection positions and transport speeds. Since one inspection module inspects one inspection item, the inspection speed can be increased, and even if the inspection modules are separated from each other, the inspection results for the same inspection object can be reliably associated with each other.

In the inspection system described above, the reading device may be installed so as to read the identification information from a direction orthogonal to the rotation direction in which the inspection object is transported along the transport direction. In order to read the identification information reliably in a shorter time, it is desirable to have such a configuration that the identification information does not appear or disappear due to the rotation of the inspection object.

An inspection method according to a second aspect of the present invention includes a reading step in which a reading device reads identification information given to each of inspection objects that are continuously conveyed along a conveying line; an inspection step in which an inspection device whose inspection position is set within a range where no missing of an article to be inspected and a change in the order of transportation from a reading position to be read inspects preset inspection items of the article to be inspected; and a storing step of associating the inspection information inspected in the inspection step with the identification information of the inspection object read in the reading step based on the position and the conveying speed of the inspection object and storing them in a storage device.

An inspection program according to a third aspect of the present invention includes a reading step in which a reading device reads identification information given to each of inspection objects that are continuously conveyed along a conveying line; an inspection step in which an inspection apparatus, whose inspection position is set within a range from a reading position where information is read, to a range in which no shortage of an inspection object or a change in transportation order occurs, inspects preset inspection items of an inspection object; and a storing step of associating the inspection information inspected in the inspection step with the identification information of the inspection object read in the reading step based on the inspection position and the conveying speed of the inspection object and storing them in a storage device.

Even in the second and third aspects, as in the first aspect, it is possible to reliably associate the identification information of the inspection target product with the inspection information. Accurate traceability can be achieved.

According to the present invention, an inspection that realizes traceability of each manufactured product by managing inspection information for each manufactured product, even in cases involving manufacturing processes in which many manufactured products are transported at high speed on a transport line and inspected. system etc. can be provided.

It is a schematic diagram which shows a mode that the inspection system which concerns on this embodiment is operate|used. It is an explanatory view explaining association of identification information and inspection information. FIG. 4 is a flow diagram showing a processing procedure of processing executed by the inspection system;

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described through embodiments of the invention, but the invention according to the scope of claims is not limited to the following embodiments. Moreover, not all the configurations described in the embodiments are essential as means for solving the problems.

FIG. 1 is a schematic diagram schematically showing how an inspection system 100 according to this embodiment is operated. In the present embodiment, it is assumed that permeable PET bottles 310 that are sequentially conveyed in a line on the conveying line 300 are inspected. The PET bottle 310 in the target inspection process is already filled with a predetermined amount of beverage, sealed with a cap 314 having an identifier 311 indicating individual information printed on the top surface, and a label 312 is attached to the side surface. ing.

Each PET bottle 310 is continuously transported at a constant speed in the direction of the white arrow while standing upright on the transport line 300 . In FIG. 1, the PET bottles 310 that are being processed by the inspection system 100 at a certain point in time are indicated by solid lines, and the other PET bottles 310 are indicated by dotted lines.

The inspection system 100 includes a reader 110 that reads an identifier 311 assigned to each PET bottle 310, and an inspection device (a label inspection device 120, a liquid volume inspection device 130, a cap inspection device) that inspects various inspection items of the PET bottle 310. 140).

Reader 110 includes controller 111 and camera module 112 . The controller 111 includes a processor (CPU: Central Processing Unit) functioning as a control calculation unit, and executes various processes instructed by the inspection program. The control calculation unit may include a calculation processing chip such as a GPU (Graphic Processing Unit) or an ASIC (Application Specific Integrated Circuit) in addition to the CPU, and a processing circuit for processing various electrical signals. The controller 111 also includes a communication unit that communicates with an external device.

Camera module 112 captures an image of identifier 311 printed on the top surface of cap 314 of PET bottle 310 that has reached a predetermined position in response to an instruction signal from controller 111 , and outputs the image signal to controller 111 . The identifier 311 is identification information including a serial number assigned to each PET bottle 310, and is represented by, for example, a two-dimensional code. The controller 111 analyzes the image signal acquired from the camera module 112 to extract identification information, and manages time information when the camera module 112 captured the identifier 311 in association with the extracted identification information.

It is desirable that the identifier 311 is printed on the upper surface of the cap 314 as described above. If the identifier 311 is printed on the upper surface of the cap 314, the identifier 311 always faces upward even if the PET bottle 310 is rotated during transportation. That is, if the camera module 112 is installed so as to be able to take an overhead view from the direction orthogonal to the rotation direction of the PET bottle 310, the entirety of the identifier 311 can be reliably imaged. The controller 111 may extract the identification information by correcting the rotation of the captured image.

In this embodiment, the inspection apparatus has three inspection modules, each of which performs an inspection of a pre-assigned inspection item. Specifically, they are a label inspection device 120 , a liquid volume inspection device 130 , and a cap inspection device 140 . The label inspection device 120 is an inspection module that inspects deviation of the label 312 attached to the side surface of the PET bottle 310 . The label inspection device 120 includes a controller 121 and four camera modules (first camera module 122, second camera module 123, third camera module 124, fourth camera module 125). The controller 121 includes a processor (CPU) functioning as a control calculation unit, and executes label inspection processing instructed by the inspection program. The control arithmetic unit may be configured to include an arithmetic processing chip such as a GPU or an ASIC in addition to the CPU, and a processing circuit for processing various electrical signals. The controller 121 also includes a communication unit that communicates with an external device.

The four camera modules synchronously take images of the sides of the PET bottle 310 that has reached a predetermined position according to an instruction signal from the controller 121 , and output the image signals to the controller 121 . The four camera modules are installed so that each of the 360° side circumferences of the PET bottle 310 can image a range of 90° or more. A full-circumference image of the side of 310 is acquired. That is, even if the PET bottle 310 rotates around the vertical axis during transportation, the image of the label 312 can always be obtained. The controller 121 analyzes the image signals acquired from the four camera modules to inspect the misalignment of the label 312 with respect to sticking, and uses the time information when the label 312 was imaged by the four camera modules as the inspection result of the label misalignment inspection. Associate and manage.

The controller 121 inspects the amount of shift and the amount of rotation with respect to the correct position and orientation defined on the side surface of the PET bottle 310 as deviation from the attachment of the label 312 . If they are within the allowable range, the inspection result of "no label deviation" is output, and if not, the inspection result of "label deviation is present" is output. The controller 121 is interconnected with the controller 111 of the reader 110 by, for example, EtherCAT (registered trademark). The controller 121 associates the analyzed inspection result with the time information as described above, generates inspection data, and transmits the inspection data to the controller 111 .

The controller 121 is also connected to the image storage server 210 via, for example, Ethernet (registered trademark). The controller 121 assigns a predetermined file name to image data generated from image signals output by the four camera modules, and transmits the image data to the image storage server 210 . The image storage server 210 stores these image data that are sequentially transmitted.

The liquid volume inspection device 130 is an inspection module that inspects the volume of the beverage filled in the PET bottle 310 . Liquid level inspection device 130 includes controller 131 and camera module 132 . The controller 131 includes a processor (CPU) functioning as a control calculation unit, and executes liquid volume inspection processing instructed by the inspection program. The control arithmetic unit may be configured to include an arithmetic processing chip such as a GPU or an ASIC in addition to the CPU, and a processing circuit for processing various electrical signals. The controller 131 also includes a communication unit that communicates with an external device.

The camera module 132 is installed so as to horizontally image the liquid surface 313 observed when the PET bottle 310 is filled with a specified amount of beverage. The camera module 132 takes an image of the PET bottle 310 that has reached a predetermined position in response to an instruction signal from the controller 131 and outputs the image signal to the controller 131 . The controller 131 analyzes the image signal acquired from the camera module 132 to inspect whether the amount of the filled liquid is appropriate, and the time information when the camera module 132 images the liquid surface 313 is used for the inspection of the liquid amount. Manage in association with results.

The controller 131 checks whether or not the liquid level extracted from the image is positioned within a prescribed range with respect to the contour of the container of the PET bottle 310 to determine whether or not the liquid volume is appropriate. If it is positioned within the specified range, the "appropriate" inspection result is output, and if it is not positioned, the "inappropriate" inspection result is output.

The controller 131 is interconnected with the controller 111 of the reader 110 by, for example, EtherCAT (registered trademark). The controller 131 associates the analyzed inspection result with the time information as described above, generates inspection data, and transmits the inspection data to the controller 111 .

The controller 131 is also connected to the image storage server 210 via, for example, Ethernet (registered trademark). The controller 131 assigns a predetermined file name to image data generated from the image signal output by the camera module 132 and transmits the image data to the image storage server 210 . The image storage server 210 stores these image data that are sequentially transmitted.

The cap inspection device 140 is an inspection module that inspects sealing of the PET bottle 310 with the cap 314 . Cap inspection device 140 includes controller 141 and ranging sensor module 142 . The controller 141 includes a processor (CPU) functioning as a control calculation unit, and executes sealing inspection processing instructed by the inspection program. The control arithmetic unit may be configured to include an arithmetic processing chip such as a GPU or an ASIC in addition to the CPU, and a processing circuit for processing various electrical signals. The controller 141 also includes a communication unit that communicates with an external device.

The ranging sensor module 142 is installed so as to measure the distance to the top surface of the cap 314 . The distance measurement sensor module 142 measures the distance to the top surface of the cap 314 of the PET bottle 310 that has reached a predetermined position in response to an instruction signal from the controller 141 and outputs the detection signal to the controller 141 . The controller 141 converts the detection signal acquired from the distance measurement sensor module 142 into a distance, inspects whether the cap 314 is sealed without floating, and the distance measurement sensor module 142 measures the top surface of the cap 314. The time information obtained is managed in association with the inspection result of the cap inspection.

The controller 141 checks whether the cap 314 is sealed without floating by checking whether the distance obtained by converting the detection signal is included in the specified range. If it is included in the specified range, the inspection result of "no float" is output, and if it is not included, the inspection result of "with float" is output.

The controller 141 is connected to the controller 111 of the reader 110 by, for example, EtherCAT (registered trademark). The controller 141 associates the analyzed inspection result with the time information as described above, generates inspection data, and transmits the inspection data to the controller 111 .

The controller 111 of the reading device 110 collects the inspection data obtained from the label inspection device 120, the liquid volume inspection device 130, and the cap inspection device 140, collects them as inspection information, and associates them with the self-generated identification information. Then, these pieces of information are transmitted to the database server 200 and stored. The controller 111 is connected to the database server 200 via, for example, Ethernet (registered trademark). The database server 200 functions as a storage device that collectively stores the identification information of each of the PET bottles 310 continuously transported along the transport line 300 and the inspection information associated therewith. For example, these pieces of information are structured as data and stored in a non-volatile memory such as an attached HDD (Hard Disk Drive).

Next, association between identification information and examination information will be described. FIG. 2 is an explanatory diagram illustrating association between identification information and examination information. In this drawing, a state in which a specific PET bottle 310a is conveyed on the conveying line 300 over time is shown in one diagram.

In the first place, when performing multiple inspections while transporting many PET bottles on a transport line at high speed, in order to manage the inspection results in association with each individual PET bottle, it is necessary to acquire identification information that identifies the individual and use it. It is preferred that the examination of individuals be performed simultaneously at the same location. However, acquisition of identification information and each inspection require different times depending on the complexity of the processing, and it is physically impossible to install various devices in one place. It's difficult to run in place at the same time. However, if the acquisition of identification information and the inspection are performed in separate locations at different times, there is a risk that the identity of the individual cannot be guaranteed.

Therefore, in the present embodiment, the inspection position of the inspection device is set within a range from the reading position P ₀ at which the reader 110 reads the identifier 311 to a range in which the transported PET bottle 310 is not missing (including sampling) and the transport order is not changed. are arranged, and based on these positions and the conveying speed v of the PET bottle 310, the inspection information corresponding to the identification information is correctly associated. The reading position P ₀ and the respective inspection positions P ₁ , P ₂ and P ₃ are defined with reference to the vertical axis of the PET bottle 310, for example. The reading device 110 and each inspection device detect the timing at which the sequentially arriving PET bottles 310 pass through these positions using a photointerrupter or the like, and perform imaging and distance detection.

The label inspection device 120 captures an image of the label 312 of the PET bottle 310a along the transport line 300 at an inspection position P ₁ separated from the reading position P ₀ by a distance D ₁ . Assuming that the PET bottle 310a passed the reading position P ₀ at time t=0, the imaging of the label 312 was performed at time t=D ₁ /v.

The liquid level inspection device 130 captures an image of the liquid surface 313 of the PET bottle 310a at an inspection position P ₂ which is separated from the reading position P ₀ by a distance D ₂ along the transport line 300 . Assuming that the PET bottle 310a passed the reading position P ₀ at time t=0, the imaging of the liquid surface 313 was performed at time t=D ₂ /v.

The cap inspection device 140 measures the distance from the PET bottle 310a to the cap 314 at an inspection position P ₃ which is separated from the reading position P ₀ by a distance D ₃ along the transport line 300 . Assuming that the PET bottle 310a passed the reading position P ₀ at time t=0, the distance measurement to the cap 314 was performed at time t=D ₃ /v.

The conveying speed v is set according to requirements such as the time required for each device to process, the interval between the PET bottles 310 moving back and forth on the conveying line 300, and the like. In this embodiment, each device has a controller and can independently execute control calculation processing, so that the processing time can be shortened and the transport speed v can be increased. In other words, the number of PET bottles 310 passed per unit time has been greatly increased.

As described above, the controller 111 of the reader 110 sequentially generates the identification information of the passing PET bottles 310 and sequentially receives respective inspection data from other controllers. The controller 111 refers to the time information described in the identification information and the time information described in the inspection data, and associates the corresponding inspection data with the identification information.

As illustrated, in DATA0 generated as identification information by the controller 111, the time when the identifier 311 was captured and the serial number recognized from the identifier 311 are described. DATA1, which is label inspection data received by the controller 111, describes the time when the label 312 was imaged and the inspection result of the label deviation. Similarly, DATA2, which is the liquid level inspection data, describes the time when the liquid surface 313 was imaged and the inspection result of the liquid volume, and DATA3, which is the cap inspection data, describes the time when the cap 314 was measured. and the inspection results of the cap floating are described.

For example, as shown in the figure, for DATA0 whose identifier 311 is imaged at time t= _T0 and whose recognized serial number is " _02a4s ", the controller 111 selects _T0 to D1 from the received DATA1. Extract DATA1 in which the time t=T1 after _/ v is described. Similarly, from the received DATA2, DATA2 describing time t=T ₂ after D ₂ /v from T ₀ is extracted. Furthermore, from the received DATA3 _, DATA3 describing time t=T3 after _D3 /v from _T0 is extracted. The controller 111 aggregates the specific DATA1, DATA2, and DATA3 extracted in this way, defines them as mutually related inspection information, and associates them with the identification information whose serial number is "02a4s." The controller 111 thus associates the corresponding inspection information for each piece of identification information.

The identification information and examination information thus associated with each other are sent to the database server 200 and stored. That is, the administrator can check the inspection information for each PET bottle 310 after the fact. In other words, even when many PET bottles 310 are transported on the transport line 300 at high speed and inspected, the traceability of each PET bottle 310 can be achieved.

FIG. 3 is a flow diagram showing a processing procedure of processing executed by the inspection system 100. As shown in FIG. The illustrated flow starts when an instruction to start inspection is received from an administrator or the like. The controller 111 acquires initial information about installation information and setting information of the inspection system 100 and the transfer line 300 in step S101. Specifically, at least the reading position P ₀ of the reading device 110, the configuration of the inspection devices (the label inspection device 120, the liquid volume inspection device 130, the cap inspection device 140), the inspection positions P ₁ , P ₂ , P ₃ , and the transport speed Get information about v.

Proceeding to step S102, the controller 111 resets its own timer and transmits a timer reset signal to the controllers of the inspection apparatuses (controllers 121, 131, 141) to synchronize the timers of the inspection apparatuses. Start a timer.

When the PET bottle 310 to be inspected starts to be transported, the process proceeds to step S103, and the reader 110 reads the identifier 311 attached to the PET bottle 310 to generate identification information. In step S104, the inspection device performs inspection of the given inspection item and generates inspection data. Step S103 is executed each time the PET bottle 310 reaches the reading position _P0 , and step S104 is executed _each time the PET bottle ₃₁₀ reaches the inspection positions P1, P2, _P3 . . Focusing on _one PET bottle ₃₁₀ , the processing is executed in the order of steps _S103 and _S104 . The inspection device may generate inspection data for the (n−1)th PET bottle 310 at the timing after the identification information for the bottle 310 is generated.

In step S105, the controller 111 refers to the time information described in the identification information and the time information described in the inspection data, and associates the identification information with the inspection information. Specifically, by referring to the time information of each inspection data, the inspection data corresponding to each other are aggregated as inspection information, and this is associated with the corresponding identification information. The controller 111 transmits the associated identification information and examination information to the database server 200 for storage.

In step S106, the inspection system 100 confirms whether or not an instruction to end the inspection has been received. If not, the process returns to step S103 to repeat each inspection process. If received, the series of processing ends.

As described above, the present embodiment has been described through one example, but the inspection system 100 is not limited to the above-described configuration and processing method. For example, the reader 110 reads the identifier 311, which is a two-dimensional code printed on the top surface of the cap 314 of the PET bottle 310, but the configuration of the reader is not limited to this. For example, if the article to be inspected has a serial number managed by an RFID tag, the reader includes an RFID reader. In the above example, the label inspection device 120, the liquid volume inspection device 130, and the cap inspection device 140 are provided as inspection devices, and are configured to inspect label misalignment, liquid volume, and cap lift, respectively. is not limited to There are various kinds of inspections for inspection objects, and any inspection item can be adopted as long as inspection objects conveyed along a conveying line are inspected. Moreover, the above-described inspection method is only an example, and various inspection methods can be adopted for one inspection item according to the properties of the inspection target product.

In addition, although the PET bottle 310 was used as the inspection object in the above embodiment, the inspection object is of course not limited to this. Products to be inspected are not limited to processed foods, for which traceability is especially required, and may be parts of industrial products.

Also, in the above example, the controller 111 of the reading device 110 functions as a storage controller of the inspection system 100, but the system configuration is not limited to this example. A control server connected to the controller 111 of the reading device 110 and the controllers of the respective inspection devices may function as the storage controller of the inspection system 100 . In this case, the control server executes the process of associating the identification information with the examination information. Moreover, the inspection system 100 may be configured to include the database server 200, and in this case, the database server 200 may function as a control server.

Here, the main configuration of the control program for the inspection system, inspection method, and inspection program described above will be summarized.
