Description

  The present invention relates to an article processing apparatus, and more particularly to an article processing apparatus suitable for an article inspection apparatus configured by combining a plurality of unit parts.

  Conventionally, an article conveying apparatus, an article inspection apparatus, an article sorting apparatus, and other article processing apparatuses, which are configured by combining a plurality of unit parts, are often used. For example, metal detection used in a production line for foods, etc. An apparatus is known in which main functional parts are unitized together with peripheral parts and the like, or a sorter is united and combined so as to exhibit a required product function (for example, Patent Document 1 (paragraph). 0003) and Patent Documents 2 and 3).

  In addition, regarding the combination of unit parts of such article processing equipment, we will prepare custom specifications and modified specifications to deal with cases where standard units cannot meet the required specifications or cannot meet low-cost requirements.

  However, in the conventional article processing apparatus as described above, depending on the type of unit parts, there may be a plurality of similar unit parts of the same type and different specifications as the maintenance parts, or there may be newly introduced unit parts. It was a lot.

  Further, in such a conventional article processing apparatus, a unit that performs its main function and a control-side unit that controls the operation of the unit are separated, and these control-side and controlled-side units are required by the apparatus. In many cases, they are selected in a predetermined combination that satisfies the performance and are connected to each other so that signals can be exchanged between them.

  Therefore, for example, at the time of maintenance work in a factory or the like that has various types of maintenance parts, either the control-side unit or the controlled-side unit may be mistakenly replaced with the same type unit other than the predetermined combination. If such an incorrect replacement is made, the controlled unit cannot respond sufficiently to the control signal of the controlling unit and cannot operate at the normal timing and speed, resulting in a decrease in efficiency, There is a possibility that the actuators of the control unit are likely to break down.

  In addition, for example, when the user switches and uses a plurality of similar unit parts of the same type and different specifications, for example, because the weight and size of the inspected object are greatly different, a combination of predetermined unit parts If the product type of the inspection object is changed without changing to, the operation cannot be performed with sufficient timing and speed within the control parameter range of either the control-side unit or the controlled-side unit, resulting in a decrease in inspection efficiency.

For example, all the control side units C11 and the like and the controlled side unit D11 and the like can be individually attached and detached.

  Further, among the control side unit C11 and the like and the controlled side unit D11 and the like that can be exchanged, at least one specific unit on the control side or the controlled side, for example, the controlled side unit D11 is exchanged with the same specifications as the unit At least one similar type unit that can be used for the same application as a specific unit and has different specifications is prepared. The unit information management control unit 25 includes the specific unit and the replaceable same type unit. Accordingly, the same type of units that have the same or similar uses and are managed as a plurality of same type units having different detailed specifications.

  A readable ID (identification information) is set in each of the control side unit C11 and the controlled side unit D11.

In addition, for a plurality of parameter types related to the control-side unit C11 and the like that control these, a plurality of control parameters set in correspondence with the type setting parameters set and input by the user for each type of article W to be inspected For example, it is stored as a plurality of parameter tables for each product type.

  The allowable setting range of the control parameter here corresponds to the characteristic range of each unit defined by the specifications of each unit, and the allowable setting range of the control parameter acquired by the parameter acquiring unit 51 is the connection destination. To determine whether or not the control parameter conforms to the specification of the unit is within the characteristic range defined by the specification of the controlled unit D11 including the transport drive motor 11 (motor output, torque, rotation speed, drive current) Etc.) is included in the allowable setting range of the control parameters according to the control specification of the control side unit C11 which is the connection destination unit (the range in which the motor output, torque, rotation speed, drive current, etc. can be set) This means that it is determined whether or not the unit D11 is within a range that can be adapted as a control target of the control side unit C11.

  As shown in FIG. 3A, when the specific unit is either the control-side unit C11 or the controlled-side unit D11, the product setting parameters (for example, motor output, conveyance speed, conveyance belt width, inspection section length) The allowable setting range of the control parameter set for a specific unit, for example, the controlled unit D11 is, for example, the torque T, the rotational speed N corresponding to the output of the transport drive motor 11, and the drive current I. Or an allowable setting range of values obtained by these functions.

  Further, as shown in FIG. 3B, when the specific unit is either the controlled side unit D21 for inspection or the control side unit C21, the kind setting parameters, for example, the types of scales having different weighing accuracy, and the weighing are possible. Corresponding to the inspection capability 1 representing the range, the measurement section length, the inspection capability 2 corresponding to the production capacity (pieces / minute), etc., the allowable setting range of the control parameter set for the controlled unit D21 for inspection is: The scale type A or B, the conveyance speed Sp, the applied voltage value A1, the measurement time A2, and the like.

  Alternatively, as shown in FIG. 3C, the specific unit is either the controlled-side unit D31 or the distribution control unit C31 for the distribution operation, or the controlled-side unit D32 for the distribution operation and the distribution unit. In the case of any one of the minute control side units C32, in response to the type setting parameter, for example, a request for sorting heavy articles or thin articles W or a request for high speed sorting, general sorting, etc., a request for the number of sorting directions, etc. Sorting method a, b, c, d set for a specific unit, for example, the control unit C31 or C32, post-inspection delay time Dt until sorting operation by sorting, sorting operation time Jt, sorting stage number Gn, etc. is there.

  The ID (identification information) set for each of the control-side unit C11 and the controlled-side unit D11 is readable as device information, and is set as information that can determine at least the type and specification of the unit. Yes. This ID may be the serial number of the corresponding unit or may include a plurality of IDs (for example, unit manufacturer ID, product ID, number for each update, etc.). It may be an identification number with a small number of bits that can identify different required specifications that make the allowable setting range of the control parameter different. Therefore, for example, it may be set by a dip switch or the like mounted on the boards of each unit.

  The parameter storage unit 52 identifies each unit of all replaceable units by unit ID, and stores the allowable setting ranges of various control parameters in the usable operation region and the set parameter values in the parameter table. ing.

  The parameter table referred to here is the difference between the reference values for various control parameters for units with basic specifications for a plurality of units of the same type for each unit type and the setting values for control parameters for other similar units. The ratio or the like may be stored.

  In addition, the parameter table here can identify the type of each control parameter by the parameter type ID, and the unit type and ID can be determined from the combination of the parameter type IDs.

  The parameter acquisition unit 51 recognizes each unit described above as a device, reads the device ID of each unit, and extracts a control parameter associated with the ID from the parameter group in the parameter table stored and stored in advance. Be able to. Needless to say, the ID reading technique at the time of device connection and the type of the ID can be arbitrarily selected from those conventionally known.

  The parameter determination unit 53 stores the control parameter for the same type of unit of the specific unit acquired by the parameter acquisition unit 51 in the parameter storage unit 52 for at least the connection destination unit (the unit that has been used together with the specific unit). Whether or not the allowable setting range of the control parameter for the same type of unit acquired by the parameter acquisition unit 51 is within the conforming range of the control parameter for the corresponding connection destination unit by comparing with the stored control parameter. Can be determined.

  Specifically, for example, when the controlled-side unit D11, which is a specific unit, is replaced with another similar unit having a transport drive motor having a larger output than the transport drive motor 11, the parameter determination unit 53 With respect to the control side unit C11 which has been controlled while setting the unit D11 to the output torque T1, the rotation speed N1, and the drive current I1, the output torque T2, the rotation speed N2, and the drive current I2 required for other similar units are Then, it is determined whether or not it falls within the range of allowable control parameters. Similarly, when the parameter determination unit 53 is exchanged for another unit of the same type for another unit that has received and transmitted signals to the controlled unit D11 that is a specific unit, It is determined whether or not the corresponding control side unit or the control side unit falls within an allowable control parameter setting range.

  In any case, the permissible setting range of the control parameter for another similar unit exchanged with a specific unit corresponds to the mounted unit (connection destination unit) on the other side that will send and receive control signals after exchange. It is determined whether or not the control parameter is within the allowable setting range. If the control parameter is out of the allowable setting range, it is a nonconforming product or out of specification that is out of the usable specification range. In that case, for example, it can be displayed and output that the replacement product of a specific unit is a non-conforming product, or the ID and model number of another similar unit recommended as a replacement product.

  On the other hand, the allowable setting range of control parameters for other similar units exchanged with a specific unit must be within the compatible range of control parameters of the other installed unit that will receive control signals after replacement. If it is determined for the set product type or the product type has not been set yet, it will be within the usable specification range. For this reason, for example, replacement from a specific unit to another similar unit and control associated therewith Confirm whether or not to allow parameter change, complete the necessary control parameter change, or it is a conforming product, but the control parameter change is waiting for permission or waiting for setting a new product type Display output can be performed.

  The output condition determination unit 54 can create a new parameter table in which the control parameters for the other same-type units after replacement are reflected in the setting information of all types, or perform parameter setting processing for rewriting the existing parameter table. Thus, when it is determined that the control parameter acquired by the parameter acquisition unit 51 is within the above-described allowable setting range, the control-side unit uses the acquired control parameter for the same type unit to control the controlled side. The output condition of the control signal to the unit is determined.

  The parameter storage unit 52 includes a memory and a storage device (not shown) together with other storage units that store various setting values, inspection conditions, product type information, inspection results, history, and the like in the weighing device 20.

  By the way, although it has been described so far that a specific unit is replaced with another known similar replaceable unit, there may be a case where a specific unit is replaced with another unknown new similar unit. It is done.

  In this case, in the above-described processing procedure, even if the other new similar unit is within the allowable setting range of the control parameter, it is not registered in the parameter table, and the ID cannot be verified.

  Therefore, in the case where the ID verification cannot be performed, the unit information management control unit 25 displays the fact that the replacement product is not registered in cooperation with the control unit 23 and confirms whether or not to make a new setting with the user. In the above, it is possible to set control parameters for other new similar units when necessary.

  Specifically, the parameter acquisition unit 51 of the unit information management control unit 25 first has an identification information reading function for reading the IDs of other similar units mounted by replacement.

  In addition, the unit information management control unit 25 specifies a specific other unit within a predetermined time after the controlled-side unit D11 is replaced with another similar unit (hereinafter also referred to as a specific other similar unit). If the ID of the same type unit cannot be read, the user is confirmed as to whether or not it is necessary to set a new control parameter for a specific other same type unit. Then, a new control parameter related to a specific other similar unit is associated with an allowable setting range corresponding to the specification of the specific other similar unit and stored in the parameter storage unit 52.

  The unit information management control unit 25, for example, with respect to another similar unit exchanged with the controlled-side unit D11 that is a specific unit, is within an allowable setting range of control parameters for a plurality of similar units of the controlled-side unit D11. It has a parameter estimation function that outputs a pseudo control signal including a signal and estimates a control parameter for the other similar unit mounted based on a response signal from the other similar unit to the pseudo control signal. .

  Specifically, the unit information management control unit 25 sends response signals Rs1, Rs2 to the control side units C11, C12, C21, C31 of the transport device 10, the weighing device 20, and the sorting device 40 as pseudo control signals. , Output a plurality of different pseudo control signals Ps1, Ps2, Ps3 that can determine whether or not Rs3 is present, whether the signal level is high or low, or whether the response signals Rs1, Rs2, and Rs3 are suitable for delay timing. The control parameter is determined based on the presence / absence and signal level of the response signals Rs1, Rs2, and Rs3 or the delay timing of the response signals Rs1, Rs2, and Rs3.

  That is, the unit information management control unit 25 uses a pseudo control signal that can be responded by a plurality of ratio control units of the same type, and whether or not the response parameters Rs1, Rs2, and Rs3 are within the allowable setting range of the control parameter. Based on the signal level of the response signals Rs1, Rs2, and Rs3 and the delay timing of the response signals Rs1, Rs2, and Rs3, the increase / decrease direction of the control parameter value and the degree thereof are estimated to estimate a suitable control parameter value. You can do that.

  Further, the unit information management control unit 25 estimates a suitable control parameter value and its settable range based on the type setting information used in the replaced mounting unit.

  In the present embodiment, the control side unit C11 and the controlled side unit D11 and the like include the transport control units C11 and C12 for transporting article processing and the controlled side units D11 and D12 for transport driving. The parameter acquisition unit 51 outputs a pseudo transport drive request signal Ps1 for the transport control unit C11 or C12, detects a response signal Rs1 corresponding to the current consumption in the controlled-side unit D11 or D12 for transport driving, and responds. The control parameters that meet the conditions are estimated by referring to the parameter table. The response signal Rs1 is, for example, a feedback signal of the rotational speed of the transport drive motor 11 or 12, and the transport speed of the conveyor 13. The control parameter can be estimated in consideration of this and the motor load corresponding to the product type setting information. .

  Further, in this embodiment, the control side unit C11 and the controlled side unit D11 and the like include the inspection control unit C21 for inspection-type article processing and the controlled side units D21 and D22 for inspection. The unit information management control unit 25 outputs an inspection command signal Ps2 to the inspection control unit C21, and estimates a control parameter based on the response signal Rs2 corresponding to the detection signal Sc or the like in the controlled side unit D21 for inspection. it can.

  Furthermore, in the present embodiment, the control-side unit C11 and the controlled-side unit D11 and the like are assigned to the distribution control units C31 and C32 for sorting by sorting the articles W for sorting-type article processing. Since the controlled controlled units D31 and D32 for operation are included, the unit information management control unit 25 outputs the distribution command signal Ps3 for the distribution control unit C31 and controls the controlled unit for the distribution command signal Ps3. The control parameter can be estimated by detecting the response signal Rs3 corresponding to the distribution operation signals Rj1 and Rj2 of D31 and D32.

  Then, the unit information management control unit 25 compares the estimated control parameter and the combination thereof with the control parameter of the registered similar unit and the combination thereof, for example, thereby controlling the control parameter among the plurality of registered similar units. Output condition including the signal form of the control signal by the combination of control parameters corresponding to the predetermined operating condition of the installed unit after replacement based on the specifications of the same type unit group and the type setting information. Hereinafter, the signal form of the control signal is also determined.

  Next, the operation will be described.

  In the present embodiment configured as described above, when a specific unit among the control side unit C11 and the controlled side unit D11 and the like, for example, the controlled side unit D11 is replaced with another similar unit corresponding thereto. The unit information management control unit 25 executes a unit information management control program as shown in FIGS.

  First, at least a unit ID is read as unit information related to a specific other same type of unit newly installed in place of the controlled side unit D11 (step S11), and stored in the parameter storage unit 52 based on the unit ID and the like. The stored registered parameter table is referred to (step S12), and it is checked whether or not a matching ID exists in the parameter table (step S13).

  If there is a matching ID, then the allowable setting range of the control parameter acquired based on the unit ID is checked against the allowable setting range of the control parameter of the connection destination unit stored in the parameter storage unit 52. (Step S14), it is determined whether or not the connection destination unit, for example, the control parameter for the control-side unit C11 is within the applicable range, and the connection destination unit C11 that has been used together with the controlled-side unit D11 is used. The suitability of a specific other similar unit is determined (step S15).

  At this time, when it is determined that the control parameter of the specific other similar unit is within the allowable setting range (conformance range) of the control parameter of the control side unit C11 stored in the parameter storage unit 52 and is compatible. (In the case of Yes in step S15), the user confirms whether to operate using a new control parameter or to change the setting (step S16), and when an operation input requesting the setting change is made, the new control parameter is changed. At least the standard operating condition or the operating condition corresponding to the currently set product type or each set product type is changed (step S17), and the control signal from the control side unit C11 etc. to the controlled side unit D11 etc. according to those control parameters The signal form is determined.

  Therefore, when an operation or setting operation that affects the combination of the control side unit C11 and the controlled side unit D11 is performed by replacing the unit with the maintenance parts, etc., a suitable control parameter is set. Therefore, it is possible to set a proper signal level, timing, etc., and effectively suppress a decrease in inspection efficiency and a decrease in durability.

  On the other hand, when it is determined that the control parameter of the specific other similar unit is out of the allowable setting range of the control parameter of the control unit C11 stored in the parameter storage unit 52 and is not compatible (No in step S15). In the case), a non-conformance display is then made to indicate that the replaced specific other similar unit is out of the conforming specification range (step S18).

  In addition, when it is determined that there is compatibility and the user confirms the intention to change the setting or operates using a new combination of control parameters, but the operation input requesting the setting change is not made (in step S16) In the case of No), next, a conformity display is displayed that indicates that the replaced specific other similar unit is within a conforming specification range and that a new control parameter setting is incomplete (step). S19).

  Furthermore, if there is no match even if the identification information of another specific similar unit matches the identification information stored in the parameter storage unit 52 (in the case of No in step S13), the fact that it has not been registered. A display is made (step S21), and the user is asked whether or not to register as a new unit together with the display (step S22), and a control signal form determination process described later is executed (step S23). .

  As shown in FIG. 5, in the control signal form determination process, first, the unit information management control unit 25 outputs, for example, a conveyance drive request signal Ps1 that is a pseudo control signal to the conveyance control unit C11 (Step S1). S31), the response signal Rs1 corresponding to the current consumption in the controlled-side unit D11 for transport driving is input (step S32), and the allowable setting range of the control parameter that satisfies the response condition is stored in the parameter storage unit 52. It is determined whether or not it is extracted from the control parameter group in the table (step S33).

  At this time, if the allowable setting range of the control parameter that satisfies the response condition can be extracted from the control parameter group in the parameter table (Yes in step S34), the output condition determination unit 54 then selects another specific parameter after the replacement. A new parameter table reflecting the product setting conditions is created or the existing parameter table is rewritten according to the control parameter allowable setting range for the same type of unit and the conditions required by the setting information of the set product type. The processing is executed, and the signal form of the control signal from the control side unit C11 to the controlled side unit D11 is determined by the control parameters after the processing (step S35).

  On the other hand, if the allowable setting range of the control parameter that matches the response condition cannot be extracted from the control parameter group in the parameter table (No in step S34), the predetermined end condition is satisfied or, for example, the predetermined number of outputs is reached. Until the condition is satisfied, the conveyance drive request signal Ps1, which is a pseudo control signal, is set as a signal different from the previous one, and the processing from the signal output to the response determination is executed again (steps S31 to S31). 33) When a predetermined termination condition is satisfied (Yes in step S36), a non-standard indication that the current replacement product cannot be used as a non-standard product is displayed (step S37), and the current processing is terminated.

  The predetermined number of times of output of the pseudo control signal here is set as the number of times necessary and sufficient to extract the allowable setting range of the control parameter satisfying the response condition from the control parameter group in the parameter table. Is the same type or the same type of unit of a specific unit, the difference between a plurality of response signals with respect to a plurality of types of pseudo control signals corresponding to the number of outputs is monitored. Even when the same type unit is a new unit that is not stored in the parameter storage unit 52, the control parameter can be accurately estimated.

  Therefore, in the present embodiment, it is possible to accurately cope with various combinations of units and custom specifications.

  The parameter acquisition unit 51 outputs a pseudo control signal to another similar unit when the identification information of the other similar unit cannot be read within a predetermined time after the specific unit is replaced with another similar unit. You may do it.

  Further, the unit information management control unit 25 relates to the specific other similar unit when the identification information of the other similar unit cannot be read within a predetermined time after the specific unit is replaced with another similar unit. The new control parameter can be registered and stored as a new unit in the parameter table of the parameter storage unit 52 in association with the allowable setting range according to the specifications of the specific other similar unit.

  In this embodiment, even when a new same type of unit is used, since other same type units have already been stored in the parameter storage unit 52, the control parameters are collated quickly and accurately. The signal output form corresponding to the new unit can be set.

  Further, even if other similar units are not already stored in the parameter storage unit 52, once the identification information is read and stored in association with control parameters newly set for other similar units, from the next time, The set control parameters can be set quickly and accurately.

  In the present embodiment, the unit information management control unit 25 uses, as a pseudo control signal, the presence / absence of the response signal Rs, the level of the signal level of the response signal Rs, or the suitability of the delay timing of the response signal Rs with respect to other similar units. A plurality of different signals that can identify any of the above are output, and whether or not the control parameter is within the allowable setting range is determined based on the presence or absence of the response signal Rs, the signal level of the response signal Rs, or the delay timing of the response signal Rs can do. Therefore, for example, by using a pseudo control signal that can be responded by a plurality of units of the same type, it is determined whether or not the control parameter is within the allowable setting range from the presence or absence of the response signal Rs, and the signal level and response of the response signal Rs Based on the signal delay timing, it is possible to specify an appropriate increase / decrease direction of the control parameter value, and it is possible to estimate and set a suitable control parameter.

  Therefore, in this embodiment, the unit information management control unit 25 outputs the pseudo conveyance drive request signal Ps1 to the conveyance control unit C11, and detects the response signal Rs corresponding to the current consumption in the controlled-side unit D11 for conveyance driving. As a result, the control parameters can be estimated. Therefore, even if the specifications of the transport drive motor 11 of the controlled-side unit D11 for transport driving are changed, suitable control parameters can be set easily and accurately.

  Furthermore, in this embodiment, the unit information management control unit 25 outputs the distribution command signal Ps3 for the distribution control unit C31, and distributes the controlled-side units D31 and D32 for the distribution operation with respect to the distribution command signal. Since the control parameter can be estimated by detecting the operation signal Rs3, a suitable control parameter can be easily and accurately set even if the specifications of the actuators of the controlled units D31 and D32 are changed.

  In addition, in this embodiment, the parameter acquisition unit 51 outputs the inspection command signal Ps2 for the inspection control unit C21, and estimates the control parameter based on the detection signal Rs2 that is a response signal of the controlled unit D21 for inspection. Therefore, even if the specification of the controlled side unit D21 is changed, suitable control parameters can be set easily and accurately.
