Description

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

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

  In such an article inspection apparatus, according to the inspection result (judgment result), a non-defective product and a defective product are sorted and sorted by a sorting unit such as a sorting device, and the defective product is excluded from a normal production line on which the good product is conveyed. I have to.

  As a sorter for such a sorting section, it has a sorting conveyor, tilts the sorting conveyor downward and drops articles by dropping down, and tilts the transport upstream side of the sorting conveyor upward. Sorting by up-out method for dropping articles (see Patent Document 1), or sorting by flipper method that swings the sorting arm and discharges the work to the outside of the conveying path along the sorting arm (patent) Reference 2) is known

  The drop-out method is swinging in the vertical direction, so it is effective for thin objects with a small thickness or inspection objects with a short length in the transport direction. Long, long items are not suitable as their ability increases. In addition, the up-out method is characterized by the fact that thick materials with thickness are not suitable.

  On the other hand, since the flipper type sorting swings in the horizontal direction, there is a gap between the conveying surface of the sorting conveyor and the sorting gate, which is not very suitable for thin objects. For this reason, in the flipper type sorting, there has been devised an apparatus that is provided with an air blow-out port through which air blows out on the sorting surface of the sorting arm 5 so as to lift the workpiece W so that a thin and lightweight object can be sorted (patent) Reference 3).

  In this way, depending on the distribution method, the items that can be selected are limited. Therefore, a distribution device according to the inspection method to be inspected is incorporated in the inspection line for selection.

  The control unit 8 executes a program stored in the storage unit 7 and performs various controls of the article inspection apparatus 1 for executing parameter setting and inspection. The control content of the control unit 8 includes display content and display mode control of the display operation unit 5.

  The distribution method setting unit 9 sets inspection conditions for each product type in accordance with an operation for setting inspection conditions in the display operation unit 5, and in particular, sets parameters relating to distribution. Further, as parameters for setting the inspection conditions, for example, there are parameters relating to inspection such as determination limits.

  The distribution method setting unit 9 determines whether the distribution method is selected based on the comparison between the distribution parameter and the distribution method as shown in the distribution method selection table shown in FIG. Candidates are displayed.

  In the distribution method selection table, an item corresponding to the superiority or inferiority of the selection based on the characteristics of the distribution method is an option for the distribution method, and the selection method is optimal among the selection methods of the distribution method possessed by the selection unit 4. It is designed to show the proper distribution method.

  The characteristics of the sorting method described above are, for example, that sorting by the air jet method is effective for a lightweight and wide air-receiving surface, but a sheet-like thin or heavy object is disadvantageous. In addition, sorting by the dropout method is effective for thin objects and short objects (conveying direction), but long objects are disadvantageous. In addition, sorting by the up-out method is effective for long objects but disadvantageous for thick objects. In addition, sorting by the flipper method is disadvantageous for sheet-like thin objects. Further, the dropout method and the up-out method in which the conveyor swings and the flipper method in which the arm swings cannot perform high-speed sorting.

  Due to such characteristics of the distribution method, in the distribution method selection table shown in FIG. 3, the distribution method selection means affects the distribution by differences in “article shape”, “article size”, “ability”, and the like. It is a distribution parameter that affects.

  “Shape of article” has three choices of “thin” / “bag” / “box”, “drop-out” for “thin”, “flipper” for “bag” and “box” It shows that “method” is suitable. The “thin object” is distinguished by the thickness of the object to be inspected (the height of the conveyance unit 2 from the conveyance surface). For example, the “thin object” is 5 mm or less.

  In addition, “size of goods” has two choices of “long” and “short”, and “up-out” is suitable for “long” and “flipper” is suitable for “short”. It shows that. In addition, “long” / “short” is distinguished by the length in the transport direction, and for example, a “long” having a length of 250 mm or more is used.

  “Capacity” has two choices of “High speed / light weight” / “Low speed / heavy”, “Air jet” for “High speed / light”, and “Low speed / heavy” This indicates that the “flipper method” is suitable. “High speed / light weight” / “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 defined as “high speed / light weight”. Yes. Further, the capability may be estimated from the belt speed and the “size of the article”. For example, a belt speed of 60 m / min and 10 mm or less may be used as the “air jet system”.

  Further, the parameters of the sorting method selection table have a priority, and when a plurality of sorting methods are targeted by an input operation, the higher priority (the one with a smaller number in FIG. 3) is displayed as a sorting method candidate. It is supposed to be.

  For example, when the “ability” is “high-speed / lightweight” and the “shape of the article” is “box”, it means that the light-weight box is inspected at high speed. In accordance with the priority order, the “air jet method” corresponding to the “high speed / light weight object” with the priority order “1” is displayed as a candidate.

  Explaining a specific example of the distribution method setting unit 9, as shown in FIG. 4, whether or not the article inspection apparatus 1 is in an operating state inspecting the inspection object W is displayed on the upper left, and below that, For example, a number set in accordance with the type of the inspection object W (for example, the type of inspection of meat, fish, processed food, medicine, etc.) is displayed.

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

  The input of the parameters relating to the distribution shown in FIG. 4 shows the case where the weight is set in the parameter input of other inspection conditions as in the case where the article inspection apparatus 1 is a weight measuring apparatus. In the case of an article inspection apparatus for which no weight is set in the input, the weight is added to the input of parameters relating to sorting and displayed.

  Then, the operator confirms the “sorting method” candidates displayed after inputting the parameters, and presses the registration button in the lower left, whereby [Flipper] is entered in the “sorting method” input field, Setting of parameters related to distribution is completed. It is also possible to input and register a “sorting method” that is not a candidate, and in this case, the candidate and the input column are displayed differently.

  Further, when the operator operates the scroll marks of Δ and ▽ at the right end, other inspection conditions (parameters related to inspection) not displayed in FIG. 4 are displayed and other inspection conditions displayed. Is entered by the operator to set other inspection conditions.

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

  First, based on the flowchart of FIG. 5, a setting operation performed by the operator to set a distribution method according to the inspection condition for each type of inspection object W will be described.

  The operator inputs the product form, the product length and thickness, and the belt speed of the inspection object W as shown in FIG. S11). When a parameter relating to distribution is input by the operator, the article inspection apparatus 1 displays a distribution method candidate 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). If the operator does not select the displayed distribution method candidate, the distribution method is selected from the display operation unit 5. A method is input (step S14), and the input distribution method is determined as a distribution method to be controlled for sorting and classifying this type of inspection object (step S15), and the setting operation of the distribution method is completed.

  In step S13, when the operator's judgment selects a displayed distribution method candidate (in the case of YES at step S13), the displayed distribution method candidate is selected as an inspection object of this type. As a distribution method to be controlled for sorting and sorting (step S15), the setting operation of the distribution method is terminated.

  As described above, the article inspection apparatus 1 according to the present embodiment is a distribution method that is a control target for sorting and inspecting an inspection object by inputting parameters relating to the distribution among inspection conditions corresponding to the product type by the operator. Candidates can be displayed and the distribution method can be determined.

  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 select the non-defective product and the defective product with respect to the sorting method sorting means determined in this way. .

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

  Among the parameters relating to the distribution, it is determined whether or not the parameter indicating the capability including the weight information is “high speed / light weight” (step S21). If the “method” distribution method is valid (step S22), the process ends. If it is not “high-speed / light-weight”, 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 relating to distribution is “long” (step S23). If it is “long”, the distribution method of “up-out method” is effective. (Step S24), and if it is not “long”, the process proceeds to the next parameter determination.

  Next, it is determined whether or not the parameter indicating the shape of the article among the parameters relating to distribution is “thin” (step S25). If it is “thin”, the distribution method of “dropout method” is effective. If it is not “thin”, the distribution method of “flipper method” is effective (step S27), and the process ends.

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