Description

The present invention relates to the selection of an article inspection device that inspects the quality of an inspected object while transporting the inspected object such as raw meat, fish, processed food, and medicine.

Conventionally, as an article inspection device for inspecting the quality of an object to be inspected, an inspection device such as a weight measuring device, an X-ray inspection device, and a metal detection device is known. Such a conventional weight measuring device measures the mass of the object to be transported, determines whether or not the obtained measured value is within the reference range, and is a non-defective product within the reference range and other non-defective products. We are sorting out good products. Further, the conventional X-ray inspection apparatus irradiates the transported object with X-rays, and inspects foreign matter contamination, mass, defects, etc. in the inspected object from the transmitted amount of the irradiated X-rays. Further, in the conventional metal detection device, an alternating magnetic field is generated in the transport line, the object to be inspected is passed through the alternating magnetic field, and whether or not metal is mixed in from the detection output when the magnetic field is passed. Is being detected.

In such an article inspection device, good products and defective products are sorted and sorted by a sorting unit such as a sorting device according to the inspection result (judgment result), and defective products are excluded from the normal production line where the good products are transported. I have to.

Such a sorting device for the sorting unit includes a sorting conveyor, and a drop-out type sorting in which the sorting conveyor is tilted downward to drop articles by a downward tilt or the transport upstream side of the sorting conveyor is tilted upward. An up-out type sorting method in which an article is dropped (see Patent Document 1), or a flipper type sorting method in which a sorting arm is swung to discharge a work out of a conveyor along a sorting arm (patented). Reference 2) is known

Since the dropout method selection is a vertical swing, it is effective for thin objects with thin thickness and objects to be inspected with short length in the transport direction, but it is effective for thick objects with thickness and length in the transport direction. Long objects with a long edge are not suitable when their abilities increase. Further, the up-out method selection is characterized in that thick and thick materials are not suitable.

On the other hand, since the flipper type sorting swings in the horizontal direction, there is a gap between the transport surface of the sorting conveyor and the sorting gate, which is not very suitable for thin materials. For this reason, in the flipper type sorting, a method has been devised in which an air outlet for blowing air so as to raise the work W is provided on the sorting surface of the sorting arm 5 so that lightweight and thin objects can be sorted (patented). See Document 3).

As described above, since the items that can be sorted are limited depending on the sorting method, a sorting device of the sorting method according to the object to be inspected is incorporated in the inspection line to perform sorting.

However, in such an inspection line, a plurality of types of objects to be inspected having different shapes, sizes, weights, etc. may be inspected by one inspection line. In this case, the inspection is performed by switching the setting of the inspection conditions, but in order to sort by the optimum distribution method according to the conditions such as the shape, size, and weight of the inspected object, a dedicated line may be constructed or the inspection may be performed. The setup of the sorting section must be changed according to the object to be inspected.

Therefore, in many cases, sorting is usually performed by a fixed sorting method, the types of objects to be inspected are limited, and the inspection is performed at the maximum capacity due to the operation time of the sorting operation by the sorting method. Sometimes not. Furthermore, in recent years, high-mix low-volume production has increased in order to meet various needs, and it is becoming more common to inspect a plurality of types of objects to be inspected by such a single inspection line.

Therefore, the present invention has been made in view of the conventional situation as described above, and is an article capable of performing sorting suitable for the inspection conditions for each type of the object to be inspected without changing the setup of the sorting portion. It is intended to provide inspection equipment.

The article inspection apparatus according to the present invention has an inspection unit that inspects the quality of the transported object to be inspected according to the inspection conditions corresponding to the inspected object, and an inspection unit that inspects the inspected object in a predetermined direction according to the inspection result of the inspection unit.

The inspection unit 3 is adapted to obtain a detection signal according to the type and size of the foreign matter contained in the inspected object W or a detection signal according to the weight of the inspected object W. Then, based on this detection signal, the determination means (not shown) is good or bad, such as whether or not the inspected object W contains a foreign substance, or whether or not the weight of the inspected object W is within a predetermined range. A determination is made, and the inspection result (pass / fail determination result) is displayed on the display operation unit 5.

When the article inspection device 1 is configured as a metal detection device, the inspection unit 3 generates an alternating magnetic field of a predetermined frequency and obtains a detection signal corresponding to a change in the magnetic field due to the object W to be inspected passing through the alternating magnetic field. It has a simple structure. The metal contained in the object W to be inspected may be magnetized by a magnetizer such as a magnet, and the residual magnetism of the magnetized metal may be detected by a magnetic sensor.

Further, when the article inspection device 1 is configured as an X-ray foreign matter detection device, the inspection unit 3 is composed of an X-ray generation source and an X-ray detector, and is subject to X-ray irradiation from the X-ray generation source. The X-ray detector detects the X-rays that have passed through the inspection object W, and the X-ray detector is configured to obtain a detection signal according to the amount of the transmission. The X-ray detector includes, for example, a plurality of photodiodes arranged in a line in a direction orthogonal to the transport direction of the object W to be transported by the transport unit 2, and a scintillator provided on the photodiode. An array-shaped line sensor is used, and 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 electric signal by a photodiode arranged below the scintillator. ..

Further, when the article inspection device 1 is configured as a weight measuring device, the inspection unit 3 is a weighing mechanism such as an electromagnetic equilibrium mechanism, in which a part of the transport unit 2 is used as a weighing table and is arranged below the weighing table. The configured load sensor measures the load of the object W to be inspected on the weighing table. The load sensor may be any mechanism as long as it can measure the weight, and may be configured by, for example, a weighing mechanism such as a differential transformer mechanism or a strain gauge mechanism.

As shown in FIGS. 2A and 2B, the sorting unit 4 has an air jet type sorting means 41, a dropout type sorting means 42, an upout type sorting means 43, and a flipper type sorting. It is equipped with means 44.

Each sorting means of the sorting method provided in the sorting unit 4 is known, and details are not shown, but the sorting operation and configuration of each sorting means will be briefly described as follows.

The air jet type sorting means 41 is a method in which air is blown from one side of the object W to be inspected and discharged to the opposite side to sort defective products, and the air nozzle 41a for blowing air is used. And an air drive unit 41b for supplying air to the air nozzle 41a. Further, the air nozzle 41a is attached to, for example, a frame (not shown) that supports the dropout type sorting means 42 so as not to be affected by the swing of the conveyor of the dropout type sorting means 42. ..

The drop-out type sorting means 42 is a method in which the inspected object W is dropped by tilting the conveyor downward and discharged out of the transport path to sort defective products, and the two sorting conveyors 42a are lined up in the transport direction. A conveyor belt 42c is hung between the rollers 42d and is provided so as to be tiltable around the roller 42d on the upstream side. An air drive unit 42b that tilts the sorting conveyor 42a downward by air supply below the sorting conveyor 42a. Is provided.

The up-out type sorting means 43 is a method in which the inspected object W is dropped by ascending and tilting the upstream side of the conveyor to be discharged to the outside of the transport path to sort defective products, and the drop-out type sorting means 42. Similarly, the transport belt 43c is hung between two rollers 43d arranged in the transport direction of the sorting conveyor 43a, and is provided so as to be tiltable with the roller 43d on the downstream side as an axis, and is provided below the sorting conveyor 43a. Is configured to be provided with an air drive unit 43b for ascending and tilting the sorting conveyor 43a by supplying air.

The flipper type sorting means 44 is a method in which the inspected object W is discharged to the side of the conveyor by swinging the arm along the transport surface of the conveyor to sort out defective products, and one end side is a rotating shaft 44c. A sorting arm 44a rotatably supported on the shaft and an air driving unit 44b for rotating the sorting arm by air supply are provided. Further, for example, the rotating shaft 44c is attached to a frame (not shown) that supports the up-out type sorting means 43 so that the sorting arm 44a swings along the transport surface of the up-out type sorting conveyor 43a. In the normal state, the sorting arm 44a is outside the sorting conveyor 43a so that the sorting arm 44a does not interfere with the swing of the conveyor of the up-out type sorting means 43.

In this way, the air jet type sorting means 41 is arranged above the dropout type sorting means 42, and the upout type sorting means 43 is arranged after the dropout type sorting means 42, and the upout type sorting means 43 is arranged. By arranging the sorting arm of the flipper type sorting means 44 so as to swing on the sorting conveyor of the sorting means 43, the space of the sorting unit 4 can be saved without interfering with each other in each operation.

The display operation unit 5 is composed of a touch panel that has both an input operation function and a display function, and the input operation is an input operation necessary for setting inspection conditions for each product type for the object W to be conveyed by the transfer unit 2. , Various setting operations and instruction operations common to all types are performed.

In addition, the display operation unit 5 has various display operations such as a setting value when a parameter for each product type and a parameter common to the product product are set, an instruction value when an instruction operation is performed, various determination results, and the like. Is to be displayed.

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

The comprehensive control unit 6 controls the entire article inspection device 1, and includes a storage unit 7, a control unit 8, a distribution method setting unit 9, and a distribution control unit 10.

The storage unit 7 stores various programs for controlling the article inspection device 1 by the control unit 8, and various parameters for the inspection unit 3 to determine the quality of the inspected object W.
Further, the storage unit 7 has the quality determination result (inspection result OK or NG) determined by the inspection unit 3 and the inspection data (weight measurement value, maximum detection signal in the inspected object) based on the detection signal used for the determination. The value, the maximum value in the object to be inspected for which the detection signal has been signal-processed, etc.), the waveform data based on the detection signal, etc. are stored as inspection result data, and the operation history such as inspection time, alarm occurrence time, etc. is also stored. ing.

The control unit 8 executes a program stored in the storage unit 7 to perform various controls of the article inspection device 1 for setting parameters and executing inspection. The control content of the control unit 8 includes control of the display content and display form of the display operation unit 5.

The distribution method setting unit 9 sets the inspection conditions for each product type according to the operation of setting the inspection conditions in the display operation unit 5, and in particular, sets the parameters related to the distribution. Further, as the parameter for setting the inspection condition, for example, there is a parameter related to inspection such as a determination limit.

The distribution method setting unit 9 determines the distribution method from the comparison between the distribution method parameters and the distribution method as shown in the distribution method selection table shown in FIG. 3 when there is an input operation of the distribution-related parameters among the inspection conditions. Candidates are displayed.

In the distribution method selection table, items corresponding to the superiority or inferiority of selection based on the characteristics of the distribution method are selected as options, and the selection method is optimal among the selection means of the distribution method possessed by the selection unit 4. It is designed to show a simple distribution method.

The above-mentioned characteristic of the distribution method is that, for example, sorting by the air jet method is effective for a lightweight object having a wide surface to receive air, but a sheet-like thin object or a heavy object is disadvantageous. In addition, sorting by the dropout method is effective for thin and short objects (transportation direction), but is disadvantageous for long objects. In addition, sorting by the up-out method is effective for long products, but disadvantageous for thick products. Further, in the sorting by the flipper method, the thin sheet-like material is disadvantageous. In addition, the drop-out method and up-out method in which the conveyor swings, and the flipper method in which the arm swings cannot be used for high-speed sorting.

Due to these characteristics of the sorting method, in the sorting method selection table shown in FIG. 3, the difference in the sorting means of the sorting method, such as "shape of article", "size of article", "ability", etc., affects the sorting. It is a distribution parameter to be exerted.

There are three choices for "article shape": "thin" / "bag" / "box". "Dropout format" for "thin" and "flipper" for "bag" and "box". It shows that "method" is suitable. The "thin material" is distinguished by the thickness of the object to be inspected (height of the transport portion 2 from the transport surface), and for example, a "thin object" having a thickness of 5 mm or less is defined as a "thin object".

In addition, there are two options for "size of goods", "long" / "short", and "up-out method" is suitable for "long" and "flipper method" is suitable for "short". It shows that there is. It should be noted that "long objects" / "short objects" are distinguished by the length in the transport direction, and for example, those having a length of 250 mm or more are referred to as "long objects".

In addition, "capacity" has two options, "high speed / lightweight" / "low speed / heavy", "air jet method" for "high speed / lightweight", and "low speed / heavy" for "low speed / heavy". It shows that the "flipper method" is suitable. "High-speed / lightweight" / "low-speed / heavy" is distinguished from the belt speed and the weight of the object to be inspected. For example, a belt speed of 60 m / min or more and 50 g or less is regarded as "high-speed / lightweight". There is. Further, the capacity may be estimated from the belt speed and the "size of the article", and for example, the belt speed of 60 m / min and 10 mm or less may be referred to as the "air jet method".

Furthermore, the parameters of the distribution method selection table have priorities, and when multiple distribution methods are targeted by input operations, the one with the higher priority (the one with the smaller number in FIG. 3) is displayed as a candidate for the distribution method. It is designed to do.

For example, if the "ability" is "high-speed / lightweight" and the "shape of the article" is "box", the priority means to inspect the lightweight box at high speed. In this case, According to the priority, the "air jet method" corresponding to the "high-speed / lightweight object" whose priority is "1" is displayed as a candidate.

Explaining a specific example of the distribution method setting unit 9, as shown in FIG. 4, it is displayed on the upper left whether or not the article inspection device 1 is in the operating state of inspecting the inspected object W, and below that, it is displayed. For example, the number set according to the variety of the object W to be inspected (for example, the type of inspection such as meat, fish, processed food, and pharmaceutical product) is displayed.

As shown in FIG. 4, there are four input items of "product form", "product length", "product thickness" and "belt speed" for inputting parameters related to distribution, and these four input items are input. Then, the candidates for the "distribution method" are displayed from the comparison between the distribution method parameters and the distribution method such as the distribution method selection table. In FIG. 4, the "product form" is [box], the "product length" is [200 mm], the "product thickness" is [100 mm], and the "belt speed" is [40 m / min]. [Flipper] is displayed as a candidate for "Distribution method".

The input of the parameters related to the distribution shown in FIG. 4 indicates the case where the weight is set in the parameter input of other inspection conditions as in the case where the article inspection device 1 is a weight measuring device, and the parameters of the other inspection conditions are set. In the case of an article inspection device in which the weight is not set in the input, the weight is added to the input of the parameters related to the distribution and displayed.

Then, the operator confirms the candidate of "distribution method" displayed after inputting the parameter, and presses the registration button at the lower left, so that [flipper] is input in the input field of "distribution method". The setting of parameters related to distribution is completed. It is also possible to input and register a "distribution method" that is not a candidate, in which case the candidate and the input field will be displayed differently.

In addition, the operator operates the scroll marks of △ and ▽ at the right end to display other inspection conditions (parameters related to inspection, etc.) not displayed in FIG. 4, and the displayed other inspection conditions. Is input by the operator to set other inspection conditions.

The distribution control unit 10 controls the sorting means corresponding to the distribution method set by the distribution method setting unit 9 so that the distribution operation is performed, and the distribution method set according to the inspection result. On the other hand, it is controlled so that the distribution operation is performed at a predetermined timing.

Next, the operation and the action effect will be described.

First, a setting operation for setting a distribution method according to the inspection conditions for each type of the object W to be inspected, which is performed by the operator, will be described based on the flowchart of FIG.

Among the inspection conditions corresponding to the product type, the operator inputs the product form, product length and thickness, and belt speed of the inspected object W as shown in FIG. 4 from the display operation unit 5 as parameters related to distribution (step). S11). When the parameter related to the distribution is input by the operator, the article inspection device 1 displays the distribution method candidates on the display operation unit 5 based on the distribution method selection table. (Step S12).

Next, the operator determines whether or not to select the displayed distribution method candidate (step S13), and if the operator does not select the displayed distribution method candidate, the distribution method is distributed from the display operation unit 5. A method is input (step S14), the input distribution method is determined as a control target distribution method for sorting and sorting the inspected object of this type (step S15), and the distribution method setting operation is completed.

In step S13, when the operator's judgment selects the displayed distribution method candidate (in the case of step S13-YES), the displayed distribution method candidate is selected as the inspected object of this type. It is determined as the distribution method to be controlled for distribution selection (step S15), and the setting operation of the distribution method is completed.

As described above, the article inspection device 1 of the present embodiment is a sorting method that is a control target for sorting and sorting the inspected object by inputting a parameter related to sorting among the inspection conditions corresponding to the product type. Candidates are displayed and the distribution method can be determined.

Then, at the time of inspection, the sorting control unit 10 controls the sorting operation according to the inspection result by the inspection unit 3 to sort out the non-defective product and the defective product with respect to the sorting method determined in this way. ..

Next, a procedure for deriving and displaying candidates for the distribution method from the parameters related to distribution will be described based on the flowchart of FIG.

Among the parameters related to distribution, it is determined whether or not the parameter indicating the ability including the weight information is "high-speed / lightweight object" (step S21), and if it is "high-speed / lightweight object", "air jet". It ends when the distribution method of "method" is effective (step S22), and if it is not a "high-speed / lightweight object", the process proceeds to the next parameter determination.

Next, it is determined whether or not the parameter indicating the size of the article among the parameters related to sorting is "long" (step S23), and if it is "long", the "up-out method" sorting method is effective. (Step S24), and if it is not a "long product", the process proceeds to the next parameter determination.

Next, it is determined whether or not the parameter indicating the shape of the article is "thin" among the parameters related to sorting (step S25), and if it is "thin", the "dropout method" sorting method is effective. If it ends as a certain (step S26) and is not a “thin material”, it ends as a “flipper method” distribution method is effective (step S27).

Then, the distribution method that is considered to be effective from the parameters related to the distribution is displayed as a candidate for the distribution method so that the operator can finally determine the selection means.

As described above, according to the article inspection device 1 of the present embodiment, the distribution control unit 10 sorts the inspected object W in the direction according to the inspection result, and the sorting unit 4 has a plurality of different sorting methods. The sorting means is controlled so as to sort and sort by using the sorting means of the sorting method suitable for the inspection condition of the object W to be inspected set by the sorting method setting means 9.

With this configuration, other sorting means are arranged on the upper part of the transport surface of the sorting means having a conveyor, and even if each sorting means performs a sorting operation individually, the arrangement does not interfere with the other sorting means. It is possible to construct the sorting unit 4 having good space efficiency even if the number of sorting means is increased for the purpose of using a more adapted sorting means.

Further, according to the article inspection device 1 of the present embodiment, the distribution method is set based on the distribution parameters including the shape, size, weight, and speed of the object W to be inspected.

With this configuration, the sorting method is set based on the sorting parameters including any of the shape, size, weight, and speed that affect the sorting in the inspection conditions for each type of the object W to be inspected. , The optimum sorting means can be set among the sorting means possessed by the sorting unit 4.
