Description

  The present invention relates to an article inspection apparatus and an article inspection system for inspecting quality of an inspection object.

  In general, an article inspection device that is installed in a production line for food, medicine, etc. and inspects the quality such as its weight, shape, and presence of foreign matter, has various inspection parameters (inspection) according to the characteristics of the inspection object. Conditions) can be adjusted and set to maintain and improve the reliability of the inspection results.

  Conventionally, as this kind of article inspection apparatus, inspection parameters such as an upper limit value, a lower limit value, a reference value, etc. for determining the quality of an inspection object are stored for a number of types such as 50 to 200 and switched according to the inspection object. In addition, there is known a method in which data including inspection results of an inspection object is stored as statistical data for each type of inspection object (for example, see Patent Document 1).

  FIG. 6 shows a table structure of a conventional article inspection apparatus. As shown in the figure, the conventional article inspection apparatus is configured to make basic settings used for the product name, inspection result statistics, and inspection for each management number. For example, the management number “001” includes the product name as the product name. “Sandwich” is also a basic setting for inspection of the weight of this sandwich. Parameters such as “200 mm” for workpiece length, “300 g” for reference value, “280 g” for lower limit value, “320 g” for upper limit value, etc. Are registered, and data such as “1000” for the total number, “998” for the OK product, and “2” for the number of NG products are stored as the inspection results after the inspection. In this table structure, an inspection object having a management number “002” and an item name “rice ball (鮭)”, an inspection object having a management number “005” and an item name “rice ball (ume)”, and the management number The inspection object whose product name is “006” and the product name is “Tsunamayo” and the inspection object whose management number is “007” and the product name is “rice ball” are both a kind of “rice ball”. Therefore, although the basic settings of the inspection are the same, they are managed with different management numbers for reasons such as managing statistics individually.

  By the way, in recent years, due to reasons such as an increase in private brands (PB) and diversification of consumer tastes, the production of high-mix low-volume products has progressed. An increasing number of products are sold as limited items. For this reason, there is a possibility that the storage area is insufficient with the number of varieties that can be stored in the conventional article inspection apparatus.

  Therefore, in this type of article inspection apparatus, the inspection management data includes the expiration date information, and the inspection management data is organized by deleting the inspection management data after the expiration date, etc. There is known a technique for reducing the above (for example, see Patent Document 2).

  Embodiments of an article inspection apparatus according to the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1 and 2, a weighing device 1 as an article inspection device includes an apparatus body 2, a transport unit 3, and a carry-in sensor 4. A sorting unit 5 is connected to the subsequent stage of the weighing device 1.

  The weighing device 1 is installed on the downstream side of the belt conveyor 14 constituting a part of the production line, and inspects meat, fish, processed foods, pharmaceuticals, etc. that are sequentially conveyed in the direction of arrow A at a predetermined interval. The weight of the object W is measured, and the obtained measurement value is output as a measurement result. Furthermore, it compares with the reference value of the upper limit and the lower limit of the preset weight, respectively, determines whether or not the obtained measurement value is within the range of the reference value, makes the one in the range a non-defective product, and out of the range It may be determined whether the product is defective or not, or the weight rank is determined corresponding to a plurality of reference values. In addition, the measurement result, the pass / fail determination result, and the weight rank determination result are displayed on the display unit 10 and are output to the selection unit 5 connected to the subsequent stage of the weighing device 1. The sorting unit 5 distributes the inspection object W according to the measurement result output from the weighing device 1, the pass / fail determination result, and the weight rank determination result.

  The apparatus main body 2 includes a weighing unit 21, a control circuit 7, a display unit 10, an operation unit 11, and a storage housing 2 a that stores these units.

  The transport unit 3 transports the inspection object W transported in the direction of arrow A from the belt conveyor 14 under predetermined transport conditions. The inspection object W is conveyed by being accelerated or decelerated so as to have an optimum speed for measurement by the running conveyor 31, further conveyed by the weighing conveyor 32, and the weight is measured by the weighing unit 21 while being conveyed. It has become so. The weighing conveyor 32 is configured to convey an object to be weighed according to predetermined conveyance conditions. Further, the inspected object W is further transported to the sorting unit 5 in the subsequent stage after the weighing and is distributed.

  The transport unit 3 includes a running conveyor 31 and a weighing conveyor 32. The run-up conveyor 31 performs the run-up of the inspection object W before the inspection object W conveyed from the preceding belt conveyor 14 moves to the weighing conveyor 32, and includes two rollers 31a and 31c, And an endless conveying belt 31b wound around the roller. The weighing conveyor 32 is supported by the upper part of the weighing unit 21 for weighing the inspection object W, and includes two rollers 32a and 32c and an endless conveying belt 32b wound around these rollers. Yes.

  The carry-in sensor 4 is configured by a transmission photoelectric sensor including a pair of light projecting units 4 a and light receiving units 4 b, and is disposed between the run-up conveyor 31 and the weighing conveyor 32. Specifically, the light projecting unit 4a is disposed on the apparatus main body 2 side of the transport belt 32b, and the light receiving unit 4b is disposed on the other side of the transport belt 32b so as to face the light projecting unit 4a. When the inspection object W passes between the light projecting unit 4a and the light receiving unit 4b, the light receiving unit 4b is shielded by the inspection object W, so that it is detected that the carry-in of the inspection object W is started. It has become. The detected carry-in start signal is output to the control circuit 7 in the apparatus main body 2.

  The weighing unit 21 is a load sensor that supports the weighing conveyor 32 and outputs a weighing signal based on the load of the object W to be inspected. The weighing unit 21 includes a scale mechanism such as an electromagnetic balance mechanism. While being conveyed, the load applied to the weighing unit 21 is measured. The weighing unit 21 may be a measuring mechanism that can measure the weight, and may be configured by a measuring mechanism such as a differential transformer mechanism or a strain gauge mechanism.

  The control circuit 7 includes a signal processing unit 71, a weighing unit 72, a setting management unit 73, and a control unit 74.

  The signal processing unit 71 receives the weighing signal from the weighing unit 21 and performs signal processing based on predetermined signal processing conditions to output a signal processed signal. The signal processing unit 71 converts an analog signal into a digital signal. A D converter is provided. Specifically, the signal processing unit 71 performs signal processing on only the low-frequency component of the weighing signal using a filter selected from a plurality of low-pass filters of different types and characteristics with respect to the weighing signal from the weighing unit 21. It is designed to pass as a signal. Note that there may be one low-pass filter selected by the signal processing unit 71 or a combination of a plurality of low-pass filters.

  The weighing unit 72 calculates a measured value of the inspection object W based on the signal processed signal output from the signal processing unit 71. Further, in the weighing unit 72, a predetermined reference time Tk has elapsed after the inspection sensor 4 detects that the inspection object W has been carried into the weighing conveyor 32, and a weighing signal is output from the weighing unit 21. A measurement value is calculated for the inspection object W. The individual weights calculated by the weighing unit 72 are stored in the setting management unit 73 as calculation data.

The weighing unit 72 performs weighing when a preset reference time Tk elapses after the carry-in sensor 4 detects that the inspection object W has been carried into the weighing conveyor 32. Here, the reference time Tk is detected by the carry-in sensor 4 that the inspection object W has started to be carried into the weighing conveyor 32, and then the inspection object W is completely transferred to the weighing conveyor 32, and further from the weighing unit 21. This means the time required for the output weighing signal to stabilize. Specifically, the reference time Tk is the speed of the weighing conveyor 32 (m / min), the length of the weighing conveyor 32 in the arrow B direction (mm), and the length of the inspection object W in the direction of arrow B. (Mm), the size of the inspection object W, the processing capacity of the line, and other conditions. Although not shown, the reference time Tk has elapsed, the test object W is moved by L ₁ reaches the mass measuring position P _S from the loading start detection position P _O, metering is performed.

  In the weighing unit 72, inspection conditions (parameters) such as the measurement range, measurement capability, and inspection accuracy are selected according to the type (particularly size) of the object W to be inspected. According to the type of the inspection object W, for example, the measurement range is selected from 6 g to 600 g, and the measurement capability is selected at a maximum of 150 pieces / min. In this case, the reference time Tk per inspection object W is set to a minimum of 400 msec, and the reference time Tk may be 400 msec or more. It is set according to capacity, production and other conditions. Since the reference time Tk is measured in a shorter time as it is closer to 400 msec, the inspection efficiency is increased, and as the distance is longer, the inspection time is longer, but the weighing accuracy is increased because it is stably conveyed on the weighing conveyor 32. Become.

  Further, according to the type of the inspected object W, for example, the measurement range is selected from 1 g to 300 g and the measurement capability is selected at a maximum of 600 pieces / min. When the measuring capacity is 600 pieces / min at the maximum, the measuring time per piece of the inspected object W is set to a minimum of 100 msec, and the size of the inspected object W, the processing capacity of the line, production, etc. It is set according to the conditions. Since the reference time Tk is measured in a shorter time as it is closer to 100 msec, the inspection efficiency is increased. As the distance is longer, the inspection time is longer, but the weighing accuracy is increased because the weighing conveyor 32 is stably conveyed. As described above, in the weighing unit 72, the inspection conditions (parameters) such as the range and capability are selected according to the type of the inspection object W.

  The weighing unit 72 is configured to determine whether the inspection object W is acceptable or not, and includes a determination circuit and the like. The basic setting (inspection) included in the calculated measurement value and the inspection table stored in the setting management unit 73. With reference to (Condition), the quality of the inspection object W is judged using this basic setting as a quality judgment criterion. Specifically, the weighing unit 72 reads the weight upper limit value Ga and the lower limit value Gb stored in advance in the setting management unit 73 with respect to the weight signal of the inspection object W, and calculates the calculated inspection object W. The weight is compared with the upper limit value Ga and the lower limit value Gb, respectively, and it is determined whether or not the weight of the inspection object W is within the allowable weight range determined by the upper limit value Ga and the lower limit value Gb. ing.

  The determination result determined in the weighing unit 72 is output to the display unit 10 and displayed as a non-defective product or a defective product. The determination result is output to the sorting unit 5 connected to the subsequent stage of the weighing device 1 so that the inspection object W is sorted as a non-defective product or a defective product. Further, the determination result is output to the operation unit 11 and statistics of the determination result for each inspection object W are stored.

  The operation unit 11 includes a storage medium, an arithmetic circuit, keys for input operation, an interface for acquiring information from an external device, and the like, and is information other than the inspection conditions and inspection conditions used in the weighing unit 72. It is inspected by the setting of a plurality of setting information relating to the inspected object W including production management information, generation of correspondence information that defines the correspondence between production management information and inspection conditions, and production management information, correspondence information, and the weighing unit 72 In addition, the statistical information of the inspection result of the inspection object W is stored. Note that “setting” in the operation unit 11 includes not only setting information setting using keys for input operation, but also setting setting information acquired from an external device via an interface.

It has become. Among these pieces of information, the product name as production management information is set by a setting operation acquired from an external device through key input or an interface. The production management information may include bar code information, package photos, registration date / time, final date / time, etc. in addition to the product name.

  The inspection number as correspondence information is generated and stored by the operation unit 11 as correspondence information that defines the correspondence between the product name set by the setting operation and the inspection condition. The operation unit 11 stores statistics as statistical information on the inspection result of the inspection object W inspected by the weighing unit 72.

  In the product table of the operation unit 11, for example, as shown in FIG. 3A, the product code “490000111111” has “sandwich” as the product name, and the basic setting (inspection for the weight of the sandwich) “001” is stored as correspondence information for defining the correspondence relationship with the “condition”, and the total number “1000”, the number of OK products “998”, and the number of NG products “2” are stored as statistics of this sandwich.

  In the operation unit 11, "rice balls", "rice balls", "rice balls", "rice balls", and "rice balls", which are one type of "rice balls", are assigned different product codes. Although stored together with individual statistics, the inspection number that defines the correspondence with the basic setting (inspection conditions) is “002”, which is the same.

  For example, when the product code “49900000222222” having the product name “rice ball (鮭)” is input, the operation unit 11 notifies the setting management unit 73 of the inspection number “002” corresponding to the product code. ing.
