Description

  The present invention relates to a combination weigher that measures and discharges an object to be weighed to a weight within a predetermined weight range.

  Conventionally, for example, there is a combination weigher as a measuring device for measuring an object to be weighed such as detergent or confectionery. In general, an object to be weighed with a combination weigher is put into a packaging machine and packed in a bag.

  In such a combination weigher, various errors may occur. For example, a combination error in which a combination within the predetermined weight range cannot be obtained, an overload error in which an excessive weighing object is thrown into the weighing hopper, a gate open / close error of a hopper such as a weighing hopper temporarily holding the weighing object, There is a zero point error of a weight sensor attached to a weighing hopper that measures the weight of an object. When such an error occurs, the worker temporarily copes with it, but often reoccurs because the cause of the occurrence is not removed. Therefore, finding out the cause of the error and removing the cause is important in preventing recurrence and increasing production efficiency. Even if the error is the same, the cause of the occurrence may be different. In order to find out the cause of the occurrence, it is important to know the operating status of the combination weigher when the error occurs and before and after.

  For example, in Patent Document 1, the operating status of a product processing apparatus such as a combination weigher is photographed with a camera, the photographed image information is stored in a memory, and the stored image information is reproduced and displayed. Possible configurations are disclosed.

  In the configuration described in Patent Document 1, a camera for photographing the operating status of a product processing apparatus such as a combination weigher, and a memory having a huge capacity for storing image information photographed by the camera are provided. There is a problem that it is necessary and requires a large amount of equipment.

  In addition, it is difficult to grasp the operation state of the combination weigher (numerically, the vibration intensity of the feeder, the vibration time, etc.) from the image information captured by the camera.

  The present invention has been made to solve the above-described problems. Operators and the like can know the exact operating state without requiring a large amount of equipment costs, and it is easy to investigate the cause of the error. It aims to provide a combination weigher.

  In order to achieve the above object, each of the combination weighers of the present invention is a hopper that can temporarily hold the objects to be weighed and then discharge them, and the total weight of the objects to be weighed is predetermined. A combination weigher body having a plurality of combination hoppers for discharging the objects to be weighed when selected as a discharge combination consisting of a combination having a value within the weight range, and controlling the combination weigher body based on operating condition information; , Information indicating the operation state of the combination weigher at the present time, sequentially generating operation state information including a part of the operation condition information consisting of numerical information, and sequentially operating state display screen data based on the operation state information A control device to be created and output, and the operating condition information can be input to the control device, and the operation status is displayed based on the operation state display screen data output from the control device. A combination weigher having an operation indicator capable of displaying a display screen on a screen, wherein the control device sequentially creates instantaneous operation information including the current operation state information and date and time information indicating the current time And storing the operation state reproduction screen data based on the operation state information of the stored instantaneous operation information and outputting it to the operation display, and the operation display The device is configured to display an operation state reproduction screen on the screen based on the operation state reproduction screen data output from the control device.

  According to this configuration, since the operation state reproduction screen including the information of the operation state display screen displayed during operation can be displayed on the screen of the operation indicator, the operation state reproduction screen when an error occurs or before and after the error occurs. By displaying, an operator or the like can know the accurate operating state of the combination weigher, and it becomes easy to investigate the cause of the error. Therefore, it is possible to find out the cause of the error, remove the cause, prevent the recurrence, and improve the production efficiency. In addition, when the operational status of the combination weigher is photographed with a camera and the image information is stored in a memory, a camera and a memory with a huge capacity are required, but such equipment is also unnecessary, There is no need for significant equipment costs.

  Further, the operation indicator is configured to be able to input a desired reproduction start date and time, and the control device receives the date and time information indicating the same date and time as the reproduction start date and time input from the operation indicator. The operation state reproduction screen data is generated as data of the operation state reproduction screen displayed on the screen at the start of reproduction based on the operation state information of the instantaneous operation information including and output to the operation display It may be.

  According to this configuration, by inputting the reproduction start date and time and displaying the operation state reproduction screen, it is possible to easily reproduce from the date and time when the operation state is desired.

  Further, the control device creates the operation state information including error occurrence information indicating that the predetermined error has occurred when a predetermined error occurs during operation, and the operation including the error occurrence information. It is configured to further create and store error information including the date and time information and the error occurrence information stored as the instantaneous operation information together with the state information, and an error information display signal is input from the operation display. The error information stored is displayed on the screen of the operation display, and includes the same date and time information as the date and time information included in the error information specified by the reproduction instruction signal input from the operation display Based on the driving state information of the instantaneous driving information, the driving state playback screen data is displayed on the screen at the start of playback. The operation state reproduction screen data is created and output to the operation indicator, and the operation indicator can input the error information display signal to the control device and is displayed on the screen. The reproduction instruction signal for designating any one of the error information may be input to the control device.

  According to this configuration, error information is displayed on the screen of the operation indicator, and by specifying any one of the displayed error information, the operating state of the combination weigher when the specified error occurs is displayed. Can be easily reproduced.

  The plurality of combination hoppers include a plurality of weighing hoppers capable of measuring the weight of the objects to be weighed, and the combination weigher body is disposed and supplied above the weighing hopper. A plurality of supply hoppers that supply the weighing hopper to the weighing hopper, a plurality of linear feeders for supplying the weighing objects to the supply hoppers, and the linear feeders to be weighed A discharge feeder comprising a combination of the combination hoppers in which the total weight of the objects to be weighed is a value within the predetermined weight range. A combination error has occurred as the error occurrence information when there is no combination of the combination hoppers to be the discharge combination when the combination processing is performed. The operation status information includes the weight of an object to be weighed, the vibration strength and vibration time of the linear feeder, and the vibration strength of the supply feeder. And the operation state information may be created so as to include the vibration time.

  According to this configuration, for example, in order to investigate the cause when a combination error occurs, for example, the weight of the objects to be weighed held in each combination hopper on the operation state reproduction screen at the time of the error occurrence Is displayed. When these weight values are too small and an object to be weighed that is appropriate for combination processing is not supplied, for example, the vibration time or vibration intensity (value corresponding to the vibration amplitude) of the linear feeder or the supply feeder. ) Is too small. In this case, what is necessary is just to investigate the cause by looking at the vibration time and vibration intensity of the linear feeder and the supply feeder.

  In addition, the control device performs the combination processing so that the total weight of the objects to be weighed is a value within the predetermined weight range, and the total number of objects to be weighed is the target number. The operation state information is configured so as to obtain a discharge combination including the combination hoppers and the operation state information includes the number of objects to be weighed held in each of the combination hoppers. May be configured to create.

  According to this configuration, for example, when a combination error occurs, the weight of the objects to be weighed held in each combination hopper is displayed on the operation state reproduction screen when the error occurs. If each of these weight values is not too small, and a combination error occurs even though an appropriate weight is being supplied, the number of items being held by each combination hopper Is displayed. Here, for example, when the target number in combination processing is an odd number, and the number of objects to be weighed held in each combination hopper is an even number, the cause is the balance of vibration time or vibration intensity of multiple linear feeders. The vibration time or vibration intensity of the linear feeder may be changed so that the objects to be weighed discharged from some of the linear feeders are an odd number.

  Further, the control device may be configured such that when the weight of the objects to be weighed held in any of the combination hoppers exceeds the upper limit value of the predetermined weight range, the objects to be weighed in the arbitrary combination hoppers as the error occurrence information. May be configured to create information indicating that an excessive amount has been introduced.

  According to this configuration, when an overload error has occurred in which the weight of the objects to be weighed held in the combination hopper exceeds the upper limit value of the predetermined weight range, each error is displayed on the operation state reproduction screen when the error occurs. The weight of the object to be weighed held by the combination hopper is displayed. Here, paying attention to the weight of the combination hopper in which an excessive charging error has occurred, the operation state reproduction screen one cycle before or before the occurrence of the error is displayed. For example, if the combination hopper is empty one cycle before the occurrence of an error, a large amount of objects to be weighed in at one time, so the vibration time of the linear feeder corresponding to the combination hopper Or it is considered that the set value of the vibration intensity is too large. In this case, the vibration time or vibration intensity of the linear feeder can be displayed to investigate the cause. Further, if the combination hopper is in a normal weight state before the occurrence of the error, it is considered that the cause is the set value of the vibration time or vibration intensity of the linear feeder corresponding to the combination hopper. For example, because the linear feeder corresponding to the combination hopper is in contact with the adjacent linear feeder, there are many objects to be weighed in the linear feeder corresponding to the combination hopper due to the vibration of the adjacent linear feeder. It is possible that it was transported.

  In addition, when the control device receives an error occurrence signal indicating that a predetermined error has occurred in the device from a subsequent or previous device of the combination weigher that forms a production line together with the combination weigher, Information indicating that an error has occurred may also be included in the error occurrence information.

  The present invention provides a combination weigher having the above-described configuration, which allows an operator or the like to know the exact operating state without requiring a large amount of equipment cost, and facilitates the investigation of the cause of the error. There is an effect that it can be provided.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing the configuration of a combination weigher according to an embodiment of the present invention.

  The combination weigher of this embodiment includes a combination weigher body 1 to which an object to be weighed is supplied from a supply device 10 that is an external device, a control device 19 that controls the operation of the combination weigher body 1, and an operation indicator 20. Is provided. The combination weigher body 1 includes a dispersion feeder (supply feeder) 11, a plurality of linear feeders 12, a plurality of supply hoppers 13, a plurality of weighing hoppers 14 and weight sensors 14 a, a plurality of memory hoppers 15, and a collecting chute 16, a collective funnel 17, and a level detector 18 are provided.

  The combination weigher main body 1 is provided with a conical dispersion feeder 11 in the center of the upper part of the apparatus, which disperses the objects to be weighed supplied from the supply device 10 radially by vibration. The supply device 10 conveys an object to be weighed supplied from a belt conveyor (not shown) by vibration and supplies it to the central portion of the dispersion feeder 11. The dispersion feeder 11 includes a conical object placement unit 11a on which an object to be weighed is placed, and a vibration device 11b that vibrates the object placement unit 11a, and is supplied from the supply device 10 to the center thereof. The object to be weighed is sent out toward the periphery by vibration. Around the dispersion feeder 11, a plurality of linear feeders 12 for radially feeding the objects to be weighed sent from the dispersion feeder 11 to the respective supply hoppers 13 by vibration are provided radially. Each rectilinear feeder 12 is provided with a transport trough 12a for placing and transporting an object to be weighed, and a vibration device 12b for vibrating the transport trough 12a. Below each linear feeder 12, a supply hopper 13, a weighing hopper 14, and a memory hopper 15 are provided correspondingly and arranged in a circular shape. The supply hopper 13 receives the object to be weighed sent from the linear feeder 12, and when the weighing hopper 14 disposed below it is empty, the gate is opened and the object to be weighed is put into the weighing hopper 14.

  The weighing hopper 14 is provided with a discharge gate so that the objects to be weighed can be selectively discharged to the memory hopper 15 and the collecting chute 16. The memory hopper 15 is disposed obliquely below the weighing hopper 14, and an object to be weighed is inserted from the weighing hopper 14 when empty.

  A collecting chute 16 is provided below the weighing hopper 14 and the memory hopper 15 arranged in a circle, and a collecting funnel 17 is disposed below the collecting chute 16. A packaging machine (not shown) is disposed below the collective funnel 17.

  Each weighing hopper 14 is attached with a weight sensor 14 a such as a load cell for measuring the weight of the object to be weighed in the weighing hopper 14, and a measurement value by each weight sensor 14 a is output to the control device 19.

  The control device 19 obtains a hopper combination (hereinafter referred to as “discharge combination”) for discharging the objects to be weighed from the plurality of weighing hoppers 14 and the memory hopper 15 by performing a combination process described later. When a discharge request signal from the packaging machine that is not used is input, the objects to be weighed are discharged onto the collecting chute 16 from the hopper selected for the discharge combination. The discharged objects to be weighed slide down the collecting chute 16 and are discharged from the collecting funnel 17 to the packaging machine.

  Further, a level detector 18 for detecting the amount of the object to be weighed on the dispersion feeder 11 is provided. For example, an ultrasonic sensor is used for the level detector 18, the layer thickness of the object to be weighed on the dispersion feeder 11 is detected, and the detection signal is sent to the control device 19. In the control device 19, the supply device 10 is controlled so as to keep the weighing object on the dispersion feeder 11 at a constant amount based on the layer thickness of the weighing object on the dispersion feeder 11 detected by the level detector 18. .

  The control device 19 is composed of, for example, a microcomputer, and includes a calculation control unit 19a including a CPU and the like, a memory such as a RAM and a ROM, a storage unit 19b that stores driving condition information, a driving program, and the like, and a calculation For example, a clock 19c including a real-time clock is provided to provide date and time information (year / month / day and time) to the control unit 19a. Then, when the arithmetic control unit 19a executes the operation program using the operation condition information set in advance, the control device 19 performs the operation control of the supply device 10 and the entire operation control of the combination weigher, A combination process for obtaining a discharge combination is performed.

  In the combination processing, a combination calculation is performed based on the weights of the weighing objects in the weighing hoppers 14 and the memory hoppers 15 measured by the weight sensor 14 a, and is held from the plurality of weighing hoppers 14 and the memory hoppers 15. The weighing hopper 14 and memory in which the total weight (combined weight) of the objects to be weighed is within a predetermined weight range (allowable weight range with respect to the target weight), and the total number of objects to be weighed is the target number One combination of the hoppers 15 is selected and set as a discharge combination. Here, as the weight of the object to be weighed in the memory hopper 15, a value measured by the weight sensor 14a in the weighing hopper 14 above the memory hopper 15 is used. For the number of objects to be weighed held in each weighing hopper 14 and memory hopper 15, for example, the weight of the objects to be weighed is divided by a preset weight value of one object to be weighed. , It is calculated by rounding off the decimal point.

  The storage unit 19b stores an operation program, operation condition information, and the like, and further stores instantaneous operation information and error information described later.

  The operation indicator 20 is configured by using, for example, a touch panel display, and displays on the screen (display screen) the input means for operating the combination weigher and setting the operation condition information thereof, the operation speed, the combination weight, and the like. Display means.

  In addition, the control device 19 inputs a signal from the operation indicator 20 and outputs a signal such as data to be displayed on the operation indicator 20.

  Further, as described above, a packaging machine for receiving and packaging the objects to be weighed discharged from the combination weigher is disposed after the combination weigher, that is, below the collective funnel 17. A production line is configured.

  In such a production line, a combination weigher usually performs combination processing in a predetermined cycle to obtain a discharge combination, and when a discharge request signal is input from the packaging machine, the hopper selected as the discharge combination. The objects to be weighed are discharged from 14, 15 and discharged to the packaging machine.

  In a packaging machine (for example, a vertical pillow packaging machine), an object to be weighed discharged from a combination weigher is received and bagged while manufacturing a bag. In this case, the objects to be weighed discharged from the combination weigher are filled into a cylindrical packaging material through a tube which is a receiving port of the packaging machine, and the upper end of the preceding bag and the lower end of the succeeding bag are A horizontal seal (transverse seal) is performed over the two. This horizontal seal is performed between the object to be weighed previously discharged from the combination weigher and the object to be weighed next, but depending on the timing, the object to be weighed bites into the horizontal seal part, and the seal Defects may occur. Here, the packaging machine is configured to transmit a seal error occurrence signal indicating that to the control device 19 of the combination weigher when this seal failure is detected.

  Further, the weight inspection device detects the weight of the object to be weighed while transporting the packaged object to be measured on a conveyor having a weight measuring function, and the weight is within a predetermined weight range set in advance. If it exceeds the upper limit value of the predetermined weight range, it is determined as “overweight product”, and if it is less than the lower limit value of the predetermined weight range, it is determined as “light product”. Here, when the determination result is not “appropriate amount product”, the weight inspection device is configured to transmit a weight error occurrence signal indicating the determination result (“overweight item”, “light weight item”) to the control device 19 of the combination weigher. Has been.

  When receiving the above-mentioned seal error occurrence signal and weight error occurrence signal, the combination weigher control device 19 stores the date and time of receiving them and the content of the error in the storage unit 19b as error information. In this way, in addition to the error occurrence signal from the subsequent device of the combination weigher that constitutes the production line together with the combination weigher, the error occurrence signal from the previous device of the combination weigher is received. May be stored in the storage unit 19b as error information. Moreover, the content of said error is also contained in the driving | running state information mentioned later.

  In the combination weigher, the linear feeder 12, the supply hopper 13, the weighing hopper 14, the weight sensor 14 a, and the memory hopper 15 that are provided in correspondence with each other constitute one weighing unit. In the following, this combination weigher is provided with 10 weighing units, the 10 weighing units are preliminarily numbered 1 to 10, and the linear feeder 12 of the nth weighing unit (n is 1 to 10), The supply hopper 13, the weighing hopper 14, and the memory hopper 15 are an n-th linear feeder 12, an n-th supply hopper 13, an n-th weighing hopper 14, and an n-th memory hopper 15, respectively.

  In this combination weigher, for example, when the power is turned on, a menu screen (not shown) is displayed on the screen of the operation display 20. On this menu screen, for example, a touch key for “operating condition setting”, a touch key for “automatic operation”, and the like are displayed.

  When the operator touches the “operating condition setting” touch key, an operating condition setting screen (not shown) used to set the operating condition information of the combination weigher is displayed. On this operating condition setting screen, values of a plurality of operating condition setting items of the combination weigher such as a target weight can be set. When the “automatic driving” touch key is touched, an automatic driving screen as shown in FIG. 2 is displayed, for example.

  2 and 3 are diagrams showing examples of an automatic operation screen (operation state display screen) of the combination weigher, that is, a screen displayed on the screen of the operation indicator 20 during the automatic operation of the combination weigher.

  In this automatic operation screen 21, a product type display area 22 for displaying the product type number and product name of the object to be weighed, a weighing unit status display area 23, an operation status display area 24, a feeder strength display area 25, “ Touch key 26 “Start / Stop”, “Recording” ON-OFF touch key 27, “Play / Setting” screen call touch key 28, “Return” touch key 29, and “Optimum combination period” touch The key 30 and the touch key 31 for “maximum speed period” are provided.

  In the weighing unit state display area 23, the state of each weighing unit can be switched and displayed in a circle in the area 23. By touching the "average weight", "combination participation rate", "combination", "effective hopper", "strength", and "time" areas displayed on the outside of the circle, the respective states are displayed in the circle. Can be displayed. FIG. 2 shows a state where the “average weight” area is touched. In this case, the circle in the area 23 is divided into 10 corresponding to each of the 10 weighing units 1 to 10, and the latest (nearest) m of the objects to be weighed put into the weighing hopper in each divided area. An average value (average weight value) of times (m is a predetermined value) is displayed. For example, the average weight value of the first weighing unit is 23.5 (g), and the average weight value of the 10th weighing unit is 27.8 (g). Further, in the innermost circle, the amount of the object to be weighed on the dispersion feeder 11 detected by the level detector 18 is shown as a weight level (a predetermined value corresponding to the amount of the object to be weighed). ing.

  FIG. 3 shows a state where the “effective hopper” area is touched in the weighing unit state display area 23. In this case, the state of each hopper of each weighing hopper 14 and each memory hopper 15 is shown in a circle in the area 23. A hopper marked with a triangle mark is an effective hopper, that is, a hopper in which the weight of the object to be weighed is equal to or lower than the upper limit value of the allowable weight range with respect to the target weight and can be selected as a discharge combination. A hopper marked with a white circle indicates that the hopper is selected for the discharge combination, and a hopper marked with a black circle indicates an object to be weighed that exceeds the upper limit of the allowable weight range with respect to the target weight, that is, Indicates that the hopper is loaded with an excessive amount of objects to be weighed (the hopper in which an excessive load error has occurred). Here, the information about the weighing hopper is shown in the area between the outermost circle and the second circle from the outside, and the information about the memory hopper is shown in the area between the second circle from the outside and the third circle from the outside. It is shown.

  When the “combination participation rate” area is touched, the number of times each hopper 14, 15 is selected as the discharge combination among the latest (most recent) k discharge combinations (k is a predetermined value). Is shown. When the “combination” area is touched, the hopper selected as the discharge combination is indicated by a white circle. In addition, when the “strength” area is touched, the vibration strength (value corresponding to the vibration amplitude) of the linear feeder of each weighing unit is shown. When the “time” area is touched, each One vibration time of the straight feeder of the weighing unit is shown.

  In addition, the operation status display area 24 displays the combined weight, the operation speed (number of discharges per minute), and the like, and the feeder strength display area 25 displays the vibration strength of the straight feeder and the vibration strength of the dispersion feeder. Yes.

  In FIG. 3, a small window 32 is opened and an error message is displayed. Here, no. Since the weighing hopper 14 of No. 8 (No. 8) has an overload error and the discharge request signal is not received from the packaging machine, it is informed that the object to be weighed cannot be discharged from the combination weigher.

  Although not shown, for example, when a touch key “histogram” is displayed on the automatic operation screen 21 and the touch key is touched, the distribution of the combined weights accumulated within a predetermined time until the present time is displayed. A histogram showing can also be displayed.

  As described above, the automatic operation screen 21 displays various information indicating the operation state at that time. In the present embodiment, the operation state information including information indicating the operation state of the combination weigher displayed on the automatic operation screen 21 is stored in the storage unit 19b as instantaneous operation information together with date and time information indicating the date and time at that time. I remember it.

  When the “stop” touch key 26 is touched on the automatic operation screen 21, the operation of the combination weigher is stopped and changed to the “start” touch key. When this “start” touch key is touched, operation of the combination weigher is started and the touch key 26 is changed to “stop”. When the “return” touch key 29 is touched, the screen returns to the display screen that called the automatic operation screen 21, here, the menu screen (not shown).

  Further, when the “recording” touch key 27 is touched, the color of the touch key 27 changes, and the above-described driving state information is recorded in the storage unit 19b as instantaneous driving information together with date / time (year / month / day and time) information. It becomes a state. When the “recording” touch key 27 is touched again in this state, the color of the touch key 27 returns to the original color and the recording is stopped. In the present embodiment, the combination weigher is normally operated in a recording state.

  The operation status information includes “average weight”, “combination participation rate” in the weighing unit status display area 23, as well as information displayed in the display areas 22, 23, 24, and 25 on the automatic operation screen. Information that can be displayed in a circle when the “combination”, “effective hopper”, “strength”, and “time” areas are touched is also included.

  When the “play / set” touch key 28 is touched, a play / set screen as shown in FIG. 4 is called, for example.

  FIG. 4 is a diagram showing an example of the playback / setting screen.

  On the reproduction / setting screen 41, the reproduction start date and time to be reproduced and displayed on the automatic operation screen is input using the touch keys 42 to 44. When the touch start key 42 for displaying the year, the touch key 43 for displaying the month, and the touch key 44 for displaying the time are touched, the ten key 46 is displayed. This can be done by touching and entering the desired number.

  When the reproduction start date / time is input in this way and the “play” touch key 50 is touched, an automatic operation reproduction screen in which the automatic operation screen at the input reproduction start date / time is reproduced is displayed.

  FIG. 5 is a diagram illustrating an example of an automatic operation reproduction screen (operation state reproduction screen) reproduced by inputting the reproduction start date and time.

  In this automatic operation replay screen 61, when the “reproduction” touch key 62 is touched, the continuous replay state is entered, the replay screens of the automatic operation screen after the reproduction start date and time are displayed in order, and the “stop” touch key 63 is touched. Stop playback. After touching the “play” touch key 62, touching the “frame advance” touch key 64 starts the top playback, touching the “rewind” touch key 65 makes the rewind playback, and touches “fast forward”. Touching the key 66 starts fast-forward playback. Further, when the “return” touch key 67 is touched, the display returns to the display screen that called the automatic operation playback screen 61, here, the playback / setting screen 41 of FIG.

  Thus, by inputting the reproduction start date and time and displaying the automatic operation reproduction screen 61, the reproduction can be easily reproduced from the date and time when the driving state is desired.

  Although the reproduction start date and time is designated here, the reproduction period may be designated. In this case, for example, unless a playback start date / time and a playback end date / time are input or a playback start date / time and a playback time are input and a playback period is designated and an operation such as stop of playback is performed, the playback period What is necessary is just to comprise so that the automatic driving | operation reproduction | regeneration screen in may be displayed continuously.

  In the recording / recording display area 47 of the playback / setting screen 41 shown in FIG. 4, information indicating the recording / recording date and time is displayed in the order in which the information was recorded.

  When an arbitrary number in the recording / recording display area 47 is selected (touched), the color of the recording / recording date / time line including the number changes, and when the “play” touch key 50 is touched, the date / time of the selected number is changed. The automatic operation screen is replayed and displayed. This is the same automatic driving reproduction screen as in FIG. For example, if No. 8 in the recording / recording display area 47 is selected and reproduced, an automatic operation screen from 8:30 on October 20, 2008 is reproduced and displayed.

  Further, when the number of the recording / recording display area 47 is selected (touched) and the “delete” touch key 51 is touched, the recording information of the selected number is deleted. The information displayed in the recording / recording display area 47 can be scrolled up and down by touching the scroll keys 48a and 48b. If there is other information indicating the date and time of recording / recording, the information can be displayed and viewed. it can.

  Further, when the “error recording” touch key 49 is touched, for example, an error recording screen 71 showing an error occurrence recording as shown in FIG. 6 is called and displayed.

  In the error recording screen 71, a plurality of pieces of error information are displayed in the error recording display area 72. The plurality of pieces of error information are numbered in the order in which the error information including the error contents and the date and time when the error occurred (error occurrence date and time) is stored, and stored in the storage unit 19 of the control device 19. .

  The contents of the error will be described. Both “missing combination” and “no combination” are combination errors for which a discharge combination cannot be obtained. With “combination missing”, the discharge combination could not be obtained at a certain timing when the combination processing was performed, but the discharge combination could be obtained at the timing when the combination processing was performed after additional objects were added to the weighing hopper. That is, it is indicated that the discharge combination cannot be obtained only once and the object to be weighed cannot be discharged once. Further, “no combination” indicates that the discharge combination cannot be continuously obtained, and the combination weigher has stopped operating. The “overload error” indicates that an object to be weighed exceeding the upper limit of the allowable weight range with respect to the target weight, that is, an excessively large object to be weighed, is supplied to the weighing hopper. The “gate open / close error” indicates that the hopper gate does not return to the set position when the gate is closed. As another error, there is a zero point error in which the zero point at the time of zero point correction of the weight sensor 14a attached to the weighing hopper is greatly deviated from the initial value (a predetermined value or more).

  Further, when the control device 19 receives the seal error occurrence signal from the packaging machine and the weight error occurrence signal from the weight inspection device, the date and time (error occurrence date and time) and the content of the error are received as error information. These are stored in the storage unit 19 b and are also displayed on the error recording screen 71.

  When an arbitrary number in the error recording display area 72 is selected (touched) on the error recording screen 71, the color of the line including the number, contents, date and time, etc. changes. When the “play” touch key 74 is touched, A screen (automatic operation reproduction screen) on which the automatic operation screen at the date and time of the selected number is reproduced is displayed. When an arbitrary number in the error recording display area 72 is selected (touched) and the “delete” touch key 75 is touched, the error information of the selected number is deleted. The information displayed in the error record display area 72 can be scrolled up and down by touching the scroll keys 73a and 73b, and if there is other record information, it can be displayed and viewed.

  FIG. 7 is a diagram showing an example of an automatic operation reproduction screen reproduced by selecting an error of an arbitrary number on the error recording screen 71 and touching the “reproduction” touch key 74.

  On this automatic operation replay screen 81, touching the “error occurrence” touch key 85 displays a replay screen of the automatic operation screen at the time of error occurrence, and every time the “1 cycle before” touch key 84 is touched, one cycle is displayed. Each time the touch key 86 “after one cycle” is touched, a replay screen of the automatic operation screen is displayed. Further, when the “reproduction” touch key 83 is touched, the continuous reproduction state is set, and when the “stop” touch key 90 is touched, the reproduction is stopped. Further, when the “return” touch key 87 is touched, the display returns to the display screen for calling the automatic operation reproduction screen 81, here, the error recording screen 71 in FIG. In the automatic operation reproduction screen 81, “average weight”, “combination participation rate”, “combination”, “effective hopper”, “strength”, displayed outside the circle in the weighing unit state display area 23, When the “time” area is touched, information about each is displayed in a circle as in the case of automatic driving. The same applies to the automatic operation reproduction screen 61 of FIG.

  As described above, the error recording screen 71 is displayed, and any one of the displayed errors is selected to display the operation state of the combination weigher when the selected error has occurred. Can be easily reproduced.

  In the automatic operation reproduction screen 81 of FIG. 7, there is a display area 82 of “Error occurrence”, and when this display area 82 is touched, for example, a small window 32 of an error message shown in FIG. 3 is displayed. Also on the automatic driving reproduction screen 81, instead of displaying the above “error occurrence”, a small window 32 of an error message shown in FIG. 3 displayed on the automatic driving screen may be displayed.

  In the automatic operation reproduction screen 81, there are an area 88 displaying “weight every time” and an area 89 displaying “number of pieces every time” outside the circle in the weighing unit state display area 23 (FIG. 5). The same applies to the automatic operation reproduction screen 61). When an area 88 displayed as “weight every time” is touched, the weights of the objects to be weighed in the weighing hoppers 14 and the memory hopper 15 are displayed in the circle of the weighing unit state display area 23. Further, when an area 89 displayed as “Number of times every time” is touched, the number of objects to be weighed in each weighing hopper 14 and memory hopper 15 is displayed in a circle in the weighing unit state display area 23. FIG. 7 shows a state in which the “weight every time” area 88 is touched.

  In the automatic operation screen displayed during actual automatic operation, the weight and the number of objects to be weighed in the hoppers 14 and 15 change rapidly, so that “weight every time” and “number of times” are displayed. However, the weight and the number of objects to be weighed in each weighing hopper 14 and memory hopper 15 are also stored in the storage unit 19b as instantaneous operation information.

  Note that the control device 19 does not consider the number of objects to be weighed in the combination process, and the weighing hopper 14 and the memory hopper 15 in which the total weight of the objects to be weighed is within the allowable range with respect to the combination target weight. The combination may be obtained as a discharge combination. In this case, the number of objects to be weighed in each weighing hopper 14 and memory hopper 15 is not calculated and is not stored as instantaneous operation information. Therefore, in this case, the “number of times each time” is not displayed on the automatic driving reproduction screen 81.

  An example of a configuration for displaying the above screen will be described.

  FIG. 8 is a functional block diagram showing some main functions realized by the control device 19 of the combination weigher. Here, the function for displaying the automatic driving reproduction screens 61 and 81 shown in FIGS. 5 and 7 and the error recording screen 71 shown in FIG. 6 will be described. FIG. 9 is a conceptual diagram showing the instantaneous operation information D2 stored in the storage unit 19b in the control device 19.

  Here, the control device 19 includes a storage unit 19b, a clock 19c composed of a real-time clock, display screen data creation means 191, input control means 192, and storage information creation means 193.

  The operation state information D1 is sequentially created for each cycle (cycle in which the combination process is performed) by means not shown in FIG. 8 of the control device 19, and is sequentially supplied to the display screen data creation means 191 and the storage information creation means 193. The The operating state information D1 includes information acquired from the outside by the control device 19 (for example, a weight value acquired from the weight sensor 14a via the input control means 192) and information created (derived) by the control device 19 ( For example, combination weight and operation speed).

  During the operation of the combination weigher, the display screen data creating means 191 normally displays the display data of the automatic operation screen based on the operation state information D1 created sequentially and the form information for creating the automatic operation screen. The data are sequentially generated and output to the operation display 20. Thereby, for example, the automatic operation screen 21 shown in FIGS. 2 and 3 is displayed on the screen of the operation display 20.

  The storage information creation means 193 creates instantaneous operation information D2 by adding the current date and time information provided from the clock 19c to the operation state information D1, and stores the instantaneous operation information D2 in the storage unit 19b. The instantaneous driving information D2 is created every time the driving state information D1 is sequentially generated, and is sequentially stored in the storage unit 19b.

  In addition, when the operation state information D1 includes error occurrence information (content of the error that has occurred), the storage information creation unit 193 extracts the error occurrence information and adds the current date and time information to the error occurrence information. Then, error information D3 is created and stored in the storage unit 19b. The instantaneous operation information D2 still contains error occurrence information. The error information D3 is information displayed in the error recording display area 72 of the error recording screen 71 in FIG. As shown in FIG. 6, in the present embodiment, the error information D3 is created by adding the current date and time information and the product number to the error occurrence information, but the product number may not be added. Further, when an error occurrence signal inputted from an external device constituting the production line together with the combination weigher, for example, a seal error occurrence signal of a packaging machine or a weight error occurrence signal of a weight inspection apparatus is inputted from the input control means 192, storage information is created. The means 193 stores the date and time of receiving them and the content of the error that occurred in the storage unit 19b as error information D3.

  As described above, the instantaneous operation information D2 and the error information D3 are stored in the storage unit 19b.

  For example, as shown in FIG. 9, the instantaneous operation information D2 includes date and time information (year / month / day and time), product type information (product number and product name) of the object to be weighed, vibration intensity and vibration time of the dispersion feeder, The vibration intensity and vibration time of the linear feeder, the weight and number of objects to be weighed held in each weighing hopper and each memory hopper, the average weight of objects to be weighed held in each weighing hopper, the combined weight and operating speed, etc. In addition, it consists of information on the error that occurred. Information obtained by removing the date and time information from the instantaneous driving information D2 is driving state information D1. This driving state information D1 includes a part of driving condition information consisting of numerical information. For example, the vibration intensity and vibration time of the straight feeder are operating condition information. The operating condition information not included in the operating state information D1 includes, for example, the gate opening times of the supply hopper, the weighing hopper, and the memory hopper.

  The operation state information D1 and the instantaneous operation information D2 are created for each cycle in which the combination process is performed, and include all information regarding the operation state of the combination weigher displayed on the automatic operation screen and the automatic operation reproduction screen. . If the interval of the start time of the combination process during normal operation is one cycle, the combination process is performed every cycle during normal operation, and the hopper 14, which is selected as the discharge combination every cycle, The object to be weighed is discharged from 15. Further, the supply of the objects to be weighed from the supply hopper 13 to the empty weighing hopper 14, the supply of the objects to be weighed from the linear feeder 12 to the empty supply hopper 13, and the object to be weighed from the dispersion feeder 11 to the linear feeder 12. The supply of the weighing object is also performed every cycle.

  For example, on the playback / setting screen 41 of FIG. 4, when the playback start date / time is input using the touch keys 42 to 44 and the “playback” touch key 50 is touched, the playback start date / time is input from the operation display 20 to the input control means. The data is input to the display screen data creation unit 191 via 192. The display screen data creation means 191 reads the instantaneous operation information D2 having the same date and time information as the reproduction start date and time from the storage unit 19b, and displays the operation state information D1 in the instantaneous operation information D2 and the first automatic operation reproduction screen. Based on the form information to be created, display data of the automatic driving reproduction screen is created and output to the operation display 20. Thereby, for example, an automatic driving reproduction screen 61 as shown in FIG. 5 is displayed on the screen of the operation display 20. In the case of normal reproduction (continuous reproduction), the instantaneous operation information D2 having date and time information after the reproduction start date and time is read out in the order of date and time (that is, storage order), and the automatic operation reproduction screen 61 is similarly obtained. Is displayed on the screen of the operation display 20. That is, the reproduction start date and time is information for designating a reproduction start screen (automatic operation reproduction screen 61 at the start of reproduction).

  When the playback start date and time and the playback end date and time are input instead of the playback start date and time and the playback period is designated, the display screen data creation unit 191 has the same date and time information as the playback start date and time. Instantaneous driving information D2 from the instantaneous driving information D2 to the instantaneous driving information D2 having the same date and time information as the reproduction end date and time is sequentially read from the storage unit 19b, and the driving state information D1 in the instantaneous driving information D2 and the first automatic Based on the form information for creating the driving reproduction screen, display data of the automatic driving reproduction screen may be sequentially created and output to the operation display 20. When the playback start date and time and the playback time are input and the playback period is designated, the display screen data creation means 191 obtains the playback end date and time from the playback start date and time and the playback end time and performs the same as described above. That's fine.

  When the “error recording” touch key 49 is touched on the reproduction / setting screen 41 of FIG. 4, an error information display signal is input from the operation display 20 to the display screen data creation unit 191 via the input control unit 192. The When an error information display signal is input, the display screen data creation means 191 reads all error information D3 from the storage unit 19b, and based on the error information D3 and form information for creating an error recording screen. Then, display data of the error recording screen is created and output to the operation display 20. Thereby, for example, an error recording screen 71 as shown in FIG. 6 is displayed on the screen of the operation display 20.

  When an arbitrary number in the error recording display area 72 is selected (touched) on the error recording screen 71 in FIG. 6 and the “play” touch key 74 is touched, the error occurrence date and time of the selected number is operated. The data is input from the display device 20 to the display screen data creation means 191 via the input control means 192. The display screen data creation means 191 reads the instantaneous operation information D2 having the same date and time information as the error occurrence date and time from the storage unit 19b, and displays the operation state information D1 in the instantaneous operation information D2 and the second automatic operation reproduction screen. Based on the form information to be created, display data of the automatic driving reproduction screen is created and output to the operation display 20. Thereby, for example, an automatic driving reproduction screen 81 as shown in FIG. 7 is displayed on the screen of the operation display 20. In the case of normal reproduction (continuous reproduction), instantaneous operation information D2 having date and time information after the error occurrence date and time is read out in the order of date and time (that is, storage order), and the automatic operation reproduction screen 81 is similarly obtained. Is displayed on the screen of the operation display 20. That is, the error occurrence date and time is information for designating the reproduction start screen (automatic operation reproduction screen 81 at the time of reproduction start).

  Although not shown, each form information for creating each screen such as the automatic operation screen, the first and second automatic operation reproduction screens, and the error recording screen is stored in a predetermined area in the storage unit 19b. The display screen data creating means 191 reads out necessary form information from the storage unit 19b and uses it.

  FIG. 10 is a diagram illustrating an example in which the automatic driving reproduction screen and the current automatic driving screen in the optimum combination period or the maximum speed period are displayed at the same time.

  For example, when the touch key 30 for “optimal combination period” or the touch key 31 for “maximum speed period” on the automatic operation screen 21 shown in FIGS. 2 and 3 is touched, for example, as shown in FIG. The automatic driving reproduction screen 61 during the speed period and the current automatic driving screen 21 can be displayed on the screen 91 as separate windows. When the visible part of the automatic driving reproduction screen 61 is touched, the automatic driving reproduction screen 61 is displayed on the front side, and the current automatic driving screen 21 is on the back side. In this state, when the visible portion of the current automatic operation screen 21 is touched, the current automatic operation screen 21 is displayed on the front side, and the automatic operation reproduction screen 61 is on the back side. In this way, the automatic driving reproduction screen 81 and the current automatic driving screen 21 can be displayed in separate windows, and the front side and the back side can be switched.

  Here, the optimal combination period is a period in which, for example, the average value of the latest 10 combination weights obtained by moving average is closest to the target weight.

  Further, the maximum speed period is a period in which the operation speed is the fastest based on the latest 10 required discharge times obtained by, for example, moving average, in other words, the combination weigher discharges a weighed object continuously 10 times. This is the shortest period.

  The control device 19 obtains the average value of the combined weight and the operating speed as needed. Then, if there is a period in which the average value of the combination weight obtained as needed is closer to the target weight, the period is updated as the optimum combination period (period start date and time end date and time) and stored in the storage unit 19b. Here, if there is a period in which the average value of the combination weights is equal to the stored optimum combination period, the period with the faster operating speed of the two periods is set as the new optimum combination period. Further, the control device 19 updates the period as the maximum speed period (period start date / time and period end date / time) and stores the period in the storage unit 19b if there is a period during which the operation speed to be obtained is faster. Here, if there is a period in which the operation speed is equal to the stored maximum speed period, a period in which the average value of the combined weights of the two periods is closer to the target weight is set as a new maximum speed period.

  When the “optimal combination period” touch key 30 or the “maximum speed period” touch key 31 in the automatic operation screen 21 is touched, the optimum combination period display signal or the maximum speed period display signal is displayed from the operation display 20 in FIG. Is input to the display screen data creation means 191 via the input control means 192. When the optimum combination period display signal or the maximum speed period display signal is input, the display screen data creation means 191 reads the period start date and time end date and time of the optimum combination period or the maximum speed period stored in the storage unit 19b. Instantaneous driving information D2 from instantaneous driving information D2 having the same date and time information as the period starting date and time to instantaneous driving information D2 having the same date and time information as the period ending date and time is sequentially read out from the storage unit 19b, and driving in the instantaneous driving information D2 Based on the state information D1 and, for example, form information for creating the first automatic driving reproduction screen, display data of the automatic driving reproduction screen is sequentially generated and output to the operation display 20. As a result, the automatic operation reproduction screen 61 is displayed on the screen 91 of the operation display 20 together with the automatic operation screen 21 as shown in FIG.

  Further, when the “return” touch key 93 is touched, the screen returns to the previous screen, for example, the automatic operation screen 21 in FIG.

  Instead of displaying the automatic driving reproduction screen 61 and the current automatic driving screen 21 in a multi-window as shown in FIG. 10, the screen display area is divided into two areas (up and down or left and right) (screen division). The automatic driving reproduction screen 61 in the optimum combination period or the maximum speed period may be displayed in one area, and the current automatic driving screen 21 may be displayed in the other area.

  As described above, the operation state can be easily compared and contrasted by displaying the automatic operation reproduction screen 61 and the current automatic operation screen 21 in the optimum combination period or the maximum speed period by multi-window or screen division.

  In the present embodiment, the operation display 20 can display an automatic operation replay screen including information on the automatic operation screen displayed during automatic operation. By displaying, it is possible to know the exact operating state of the combination weigher, and it becomes easy to investigate the cause of the error. Therefore, it is possible to find out the cause of the error, remove the cause, prevent the recurrence, and improve the production efficiency. Here, the automatic operation reproduction screen can display numerical information such as the vibration time and vibration intensity of the linear feeder 12 and the weights of the objects to be weighed in the weighing hoppers 14 and the memory hoppers 15. You can know the state. In addition, when the operational status of the combination weigher is photographed with a camera and the image information is stored in a memory, a camera and a memory with a huge capacity are required, but such equipment is also unnecessary, There is no need for significant equipment costs.

  For example, when a combination error such as “missing combination” or “no combination” occurs, in order to investigate the cause, for example, in the automatic operation reproduction screen at the time of error occurrence, Is touched to display the weight values of the objects to be weighed held in the hoppers 14 and 15. If each of these weight values is too small and an appropriate amount of objects to be combined is not supplied, for example, the vibration time or vibration strength of the dispersion feeder 11 or the linear feeder 12 is too small, or It is thought that the cause is that too few objects to be weighed are supplied from the supply device 10. In this case, what is necessary is just to investigate and investigate the cause further by looking at the vibration time and vibration intensity of the dispersion feeder 11 and the linear feeder 12, the weight level of the object to be weighed on the dispersion feeder 11, and the like.

  In addition, the weight value of the objects to be weighed held in the hoppers 14 and 15 is not too small, and an error occurs when a combination error has occurred even though the objects to be weighed in an appropriate weight are supplied. An area 89 labeled “Number of times” in the weighing unit status display area 23 at the time is touched to display the number of objects to be weighed held in the hoppers 14 and 15. Here, for example, when the target number in the combination processing is an odd number and the number of objects to be weighed held in the hoppers 14 and 15 is an even number, the balance of vibration time or vibration intensity of the plurality of linear feeders 12 is achieved. Is considered to be the cause. In this case, it is only necessary to change the vibration time or the vibration intensity of some of the linear feeders 12 so that the objects to be weighed discharged from some of the linear feeders 12 become an odd number.

  Further, when an overload error has occurred in which the weight value of the object to be weighed held in the weighing hopper 14 exceeds the upper limit value of the allowable weight range with respect to the target weight, the weighing unit status display area 23 at the time of the error occurrence The area 88 labeled “every time weight” is touched to display the weight of the objects to be weighed held in the hoppers 14 and 15. Here, paying attention to the weight of the weighing hopper 14 in which an overload error has occurred, an error occurs when the touch key 84 “one cycle ago” is touched one or more times on the automatic operation reproduction screen 81 as shown in FIG. Displays the state one cycle before or before the hour. For example, if the weighing hopper 14 is empty one cycle before the occurrence of an error, a large amount of objects to be weighed are loaded at one time. Therefore, the vibration time or vibration of the linear feeder 12 of the weighing unit This is probably because the strength setting is too large. In this case, the set value of the vibration time or vibration intensity of the linear feeder 12 of the weighing unit may be reduced. In addition, for example, if the state of the effective hopper has continued before the time of the error occurrence, such as one cycle before the error occurrence, two cycles before, or the like, the setting of the vibration time or vibration intensity of the linear feeder 12 of the weighing unit The value is not considered to be the cause. For example, the linear feeder 12 of the weighing unit is in contact with the adjacent linear feeder 12, and the vibration of the adjacent linear feeder 12 causes the linear feeder 12 of the weighing unit to vibrate. It can be considered that a large number of objects to be weighed were conveyed. In this case, the position of the straight feeder 12 may be adjusted.

  As described above, even if they are the same error, the cause thereof is not necessarily the same, and it becomes easy to investigate the cause of the error from the information displayed on the automatic operation reproduction screen.

  In the present embodiment, the combination weigher of FIG. 1 having the weighing hopper 14 and the memory hopper 15 is given as an example as a hopper participating in the combination (combination hopper). However, the present invention is not limited to this configuration. For example, the memory hopper 15 may not be provided, and the combination hopper may include only a plurality of weighing hoppers 14. Various other changes are possible. Further, the arrangement of the combination hoppers is not limited to a circular shape, and may be a linear arrangement, for example.

  Note that the control device 19 does not necessarily need to be configured as a single control device, and a plurality of control devices may be arranged in a distributed manner and may be configured to control the operation of the combination weigher in cooperation with each other. Good.

  The combination weigher according to the present invention is useful as a combination weigher or the like that allows an operator or the like to know an accurate operating state without incurring a large amount of equipment costs and facilitates the investigation of the cause of the error.
