Description

  The present invention relates to a weighing device for weighing an object to be weighed, and more particularly to a weighing device suitable for packing an object to be weighed in a predetermined weight range in a container such as a tray or a bag.

  2. Description of the Related Art Conventionally, weighing devices are used to pack objects to be weighed in a predetermined weight range in containers such as trays and bags in production factories and supermarkets that produce foods.

  In many cases, a combination weigher is used to produce a quantitative pack of objects to be weighed in a predetermined weight range.

  The combination weigher has a plurality of measuring instruments, and the total weight, which is a combined weight obtained by variously combining the weights of the objects to be weighed by the measuring instruments, is within a predetermined weight range and equal to the target combination weight. It is a weighing device that performs a combination operation for selecting the closest combination of weights as an appropriate amount combination.

  By the way, in the case of objects to be weighed that are irregular in shape, easily damaged, and whose commercial value decreases when damaged, such as carrots, mushrooms, mentaiko, etc. It is difficult to automatically supply and take out (discharge) from the measuring instrument.

  For this reason, in the case of such an object to be weighed, a manual combination weigher is used in which the object to be weighed is supplied to the weighing instrument and the object to be weighed is taken out of the weighing instrument manually. The

  In a manual combination weigher, an operator manually supplies an object to be weighed to each weighing instrument, and the combination weigher performs a combination calculation as described above to select a plurality of weighing instruments in an appropriate amount combination. For example, the combination weigher individually lights each indicator lamp corresponding to each selected measuring instrument in order to instruct the operator of each measuring instrument of the selected appropriate amount combination. As a result, the operator manually takes out the objects to be weighed from the measuring instruments whose indicator lamps are lit, collects them in containers such as trays, and packs them.

  As described above, in the combination weigher, it is necessary to take out the objects to be weighed from each of the plurality of measuring instruments selected as an appropriate combination by the combination calculation and collect them in one container.

  For this reason, for example, in the case of an object to be weighed that is difficult to handle in number units such as chopped vegetables such as cut green onions, side dishes such as potato salad, and as an appropriate amount combination by combination calculation It is necessary to take out the objects to be weighed from a plurality of selected measuring instruments neatly so as not to remain and collect them in one container, which is a troublesome and troublesome operation.

  For example, as shown in Patent Document 1, some combination weighers can perform weighing with each measuring instrument without performing combination calculation.

JP 2008-107180 A

  However, the weighing device of Patent Document 1 is for producing a product in which a predetermined number of objects to be weighed such as tomatoes are packed, and is based on the assumption that the objects to be weighed are supplied to the measuring device in units of pieces. In addition, it is difficult to handle in units such as chopped vegetables such as cut onions as described above and sugar beet such as potato salad, and it cannot be applied to the weighing of objects to be weighed.

  For this reason, in the past, when it was difficult to handle in a unit of number and to produce a fixed amount pack of an object to be weighed, an operator would not use a manual combination weigher. As with a weighing device such as an upper pan scale, place a container such as a tray on one weighing pan, tare the container, and weigh the object to be in the specified weight range while looking at the weight display. We perform the weighing work of manually feeding the container on the plate.

  In this weighing method, the operator needs to check whether or not the weight of the object to be weighed is within a predetermined weight range by looking at the weight display, and the displayed value may be mistaken. In addition, since one worker supplies the objects to be weighed to one weighing pan and produces a quantitative pack, it is necessary to increase the number of weighing devices and the number of workers in order to increase the production volume of the quantitative pack. There is.

  The present invention has been made in view of the above points, and it is an object of the present invention to increase the efficiency of weighing work of an object to be weighed that is difficult to handle in a unit of number and has adhesive properties.

  In order to achieve the above object, the present invention is configured as follows.

  (1) In the weighing device of the present invention, the supply and removal of the objects to be weighed are each manually performed, and each of the weighing units weighs the weight of the objects to be weighed, and the weighing parts are respectively weighed. A determination unit that determines whether each weight of the object to be weighed is light, appropriate, or excessive with respect to a predetermined weight range, and individually corresponds to the plurality of weighing units, and the determination unit A plurality of notifying units that notify the determination result for each corresponding weighing unit, and the determination unit is the weight of the weighing object of the weighing unit determined to be light among the plurality of weighing units. And the weighing unit determined to be light weight and the weighing unit determined to be excessive are the appropriate amount between the weight of the weighing object of the weighing unit determined to be excessive. The weight relationship useful for the weighing unit The informing unit determines whether or not the useful weight relationship is established when the judging unit determines that the useful weight relationship is established, and is the light weight. The determined weighing unit and the measured weighing unit determined to be excessive are notified.

  According to the weighing device of the present invention, each of the plurality of weighing units supplied with the objects to be weighed individually corresponds to each weighing unit, which is light, appropriate amount, or excessive amount with respect to a predetermined weight range. Since it is notified by each of the plurality of notification units, an appropriate amount of the weighing unit is obtained by adding an object to be weighed to the weighing unit that is light and removing a part of the object to be weighed from the weighing unit that is excessive. The weight of the object to be weighed can be made appropriate for each of the plurality of weighing units.

  This eliminates the need to collect the objects to be weighed in a plurality of weighing units selected in an appropriate amount combination within a predetermined weight range as in the case of weighing by performing a combination calculation, for example, in units of pieces. It is possible to easily weigh even objects to be weighed that are difficult to handle and require a lot of work to collect in one object, such as objects to be weighed.

  Moreover, it is not necessary to visually check whether or not the operator has entered the predetermined weight range as in the case of weighing while looking at the weight display with one weighing unit like a weighing device such as an upper pan scale. Since each of the plurality of measuring units measures, it is possible to measure efficiently.

  In addition, in order to make the weighing unit an appropriate amount of the weighing unit among the lightweight weighing unit and the excessive amount of weighing unit, the weighing unit that has a useful weight relationship is informed so that the operator can Light weight weighing units and overweight weighing units that have a useful weight relationship can be recognized, and the operator can adjust the weight of the objects to be weighed between the two weighing units. By using the useful weight relationship that is established, an appropriate amount of the weighing unit can be efficiently obtained.

  (2) In a preferred embodiment of the present invention, the useful weight relationship is obtained by adding the weight of the weighing unit determined to be light weight and the weight of the weighing unit determined to be excessive. One half of the added weight is the first useful weight relationship that falls within the predetermined weight range.

  According to this embodiment, the first useful weight relationship is that a half of an added weight obtained by adding the weight of the object to be weighed in the light weight measuring part and the weight of the object to be weighed in the excessive amount of weighing part is predetermined. The weight range, that is, the weight of the weighing object in the lightweight weighing part and the weight of the weighing object in the excessive weighing part is the sum of the weights of the weighing objects for the two weighing parts. It becomes weight.

  Therefore, by removing a part of the object to be weighed from the excessive weighing unit that satisfies the first useful weight relationship and adding it to the lightweight weighing unit, the two weighing units can be weighed together in an appropriate amount. Can be part.

  Since the light weight weighing unit and the overweight weighing unit in which the first useful weight relationship is established are informed to the worker, the worker selects a part of the object to be weighed in the overweight weighing unit, By switching to a lightweight weighing unit, the two weighing units can both be changed to appropriate weighing units, which is an efficient weighing operation.

  (3) In another preferred embodiment of the present invention, among the plurality of weighing units, the first useful weight relationship is established, and the weighing unit determined to be lightweight and the excess amount are determined. When there are a plurality of sets with the weighing unit, the plurality of notification units are the weighing unit determined to be lightweight among the plurality of sets in which the first useful weight relationship is established, and The measurement unit that is determined to be in excess is notified of the set at the closest position.

  According to this embodiment, when there are a plurality of pairs of lightweight weighing units and overweight weighing units that satisfy the first useful weight relationship, it is easy for the operator to transfer the objects to be weighed. The set in which the lightweight measuring part and the excessive measuring part are in the closest position is notified.

  (4) In another embodiment of the weighing device of the present invention, among the plurality of weighing units, the first useful weight relationship is established, and the weighing unit determined to be lightweight and the overload. When there are a plurality of sets with the determined measuring unit, the plurality of notification units change the notification mode for each of the plurality of sets in which the first useful weight relationship is established.

  According to this embodiment, when there are a plurality of pairs of lightweight weighing units and overweight weighing units that satisfy the first useful weight relationship, the notification mode differs for each group. The first useful weight relationship can be established, and a plurality of pairs of lightweight weighing units and overweight weighing units can be recognized for each group, that is, which overweight weighing unit is to be weighed It is possible to recognize whether or not it should be transferred to a lightweight weighing unit.

  (5) In a preferred embodiment of the weighing device according to the present invention, the weighing device includes an external scale for weighing the weight of the weighing object in a storage container in which the weighing object supplied to the plurality of weighing units is stored, and the determination The weight of the weighing object to be weighed by the external scale is defined as a feeding weight of the weighing object supplied from the storage container to the plurality of weighing units, and the supply weight and the plurality of weighing units Among them, it is useful to set the weighing unit determined to be lightweight as the weighing unit determined to be the appropriate amount between the weight of the weighing object of the weighing unit determined to be lightweight. And determining whether or not the second useful weight relationship is established, and when the determination unit determines that the second useful weight relationship is established, the notification unit Weighing determined to be light weight, satisfying two useful weight relationships To notify.

  According to this embodiment, an appropriate amount of the lightweight measuring unit is measured between the supply weight of the object to be weighed that is taken out of the storage container and supplied to the measuring unit and the weight of the object to be weighed of the lightweight measuring unit. When the second useful weight relationship useful for making a part is established, the lightweight weighing unit is notified, so that the operator can make a lightweight weighing unit with the second useful weight relationship established. The operator can use the second useful weight relationship by adjusting the weight of the object to be weighed in the lightweight weighing unit with the supply weight of the object to be weighed supplied from the storage container. Thus, an appropriate amount of the weighing unit can be efficiently obtained.

  (6) In another embodiment of the weighing device according to the present invention, the second useful weight relationship is obtained by adding the supplied weight and the weight of the weighing object of the weighing unit determined to be light. The additional weight is a weight relationship that falls within the predetermined weight range.

  According to this embodiment, the second useful weight relationship is the addition of the weight of the object to be weighed taken out of the storage container and supplied to the weighing part and the weight of the object to be weighed in the lightweight weighing part. Since the weight is in a weight relationship that falls within a predetermined weight range, the operator additionally supplies the object to be weighed taken out of the storage container to the lightweight weighing unit that is informed when the second useful weight relationship is established. By doing so, a lightweight measuring part can be made into an appropriate amount of measuring part.

  (7) In another embodiment of the weighing device according to the present invention, the determination unit is configured to measure the supplied weight and an object to be weighed of two weighing units determined to be lightweight among the plurality of weighing units. Whether or not a third useful weight relationship useful for making the two weighing units determined to be lightweight into the weighing units determined to be the appropriate amount is established between the respective weights. And when the determination unit determines that the third useful weight relationship is established, the notification unit is configured to satisfy the third useful weight relationship. The two weighing units determined to be present are notified.

  According to this embodiment, the two lightweight weighing units are provided between the supply weight of the objects to be weighed that are taken out from the storage container and supplied to the weighing unit, and the respective weights of the weighing items of the two lightweight weighing units. When the third useful weight relationship useful for making the portion into an appropriate amount of weighing portion is established, the two lightweight weighing portions are informed, so that the operator has a third useful weight relationship. It can recognize the two lightweight weighing units that are established, and the operator can adjust the weight of the objects to be weighed in the two lightweight weighing units with the supply weight of the objects to be weighed out from the storage container. By doing so, two lightweight weighing parts can be efficiently converted into two appropriate weighing parts by utilizing the third useful weight relationship.

  (8) In another embodiment of the weighing device of the present invention, the third useful weight relationship is the supply weight and the weights of the weighing objects of the two weighing units determined to be lightweight. A weight relationship in which ½ of the added weight obtained by adding is within the predetermined weight range.

  According to this embodiment, a third useful weight relationship is the weight of the object to be weighed that is removed from the storage container and supplied to the weighing unit, and the respective weights of the objects to be weighed by the two lightweight weighing units. 1/2 of the added weight is within the predetermined weight range, that is, the added weight obtained by adding the weight of the objects to be weighed supplied from the storage container and the weight of the objects to be weighed by the two lightweight weighing units. Is the weight relationship that is the weight of the two objects to be weighed by an appropriate amount of the weighing unit.

  Therefore, the operator adds the object to be weighed taken out of the storage container to one of the two lightweight measuring units that satisfies the third useful weight relationship. Then, this one weighing unit becomes an excessive amount weighing unit, and the first useful portion is between the weight of the object to be weighed in this excessive amount weighing unit and the weight of the object to be weighed in the other light weight measuring unit. A weight relationship is established, and by using this first useful weight relationship, an object to be weighed in the one excess weighing unit is additionally supplied to the other lightweight weighing unit. The two metering units can both be an appropriate amount of metering unit.

  (9) In still another embodiment of the weighing apparatus according to the present invention, the determination unit is configured such that a weight difference between a lower limit weight that defines the predetermined weight range and a weight of an object to be weighed by the measurement unit determined to be lightweight. And determining a weight difference between an upper limit weight that defines the predetermined weight range and a weight of an object to be weighed in the weighing unit that is determined to be excessive, and the notification unit is determined to be the light weight. The weighing unit that has been determined and the weighing unit that has been determined to be in excess are reported according to the weight difference determined by the determination unit.

  According to this embodiment, the weight difference between the lower limit weight of the predetermined weight range and the weight of the object to be weighed in the light weight measuring unit, and the weight between the upper limit weight of the predetermined weight range and the weight of the object to be weighed in the excessive amount measuring unit. Since the difference is reported, the operator can recognize the shortage of objects to be weighed in the light weight measuring unit and the excessive amount of objects to be weighed in the overweight weighing unit. It becomes possible to recognize the adjustment weight of the object to be weighed that is necessary for making the measuring unit an appropriate amount of the measuring unit, and it is possible to efficiently make an appropriate amount of the measuring unit.

  (10) In another embodiment of the weighing device of the present invention, each of the plurality of weighing units has a weighing pan to which the object to be weighed is supplied, and each of the plurality of notification units is in the vicinity of the weighing pan. The weighing device selects an appropriate combination of the weighing pans in which the combination weight of various weights of the objects to be weighed supplied to the plurality of weighing pans falls within the allowable weight range. It is a combination weigher capable of performing combination calculation and notifying the weighing pan of the appropriate amount combination with the indicator lamp.

  According to this embodiment, it is possible to perform individual weighing without using combination calculation, with the combination weigher performing combination calculation as the weighing unit for each of the plurality of weighing pans. As a result, the weighing device can be used as a combination weigher. On the other hand, for example, when weighing an object to be weighed that is difficult to handle in a number unit and has adhesiveness, a combination operation is performed. It can be used as a weighing device having an individual weighing unit for each of a plurality of weighing pans.

  According to the present invention, each of the plurality of weighing units can be individually weighed to obtain an object to be weighed within a predetermined weight range, and within a predetermined weight range as in the case of weighing by performing a combination calculation. It is not necessary to collect the objects to be weighed from a plurality of weighing units selected for the appropriate amount combination into one, for example, it is difficult to handle in units of number and has an adhesive property. Even the objects to be weighed that require a lot of work to collect in one can be weighed efficiently.

  Moreover, it is not necessary to visually check whether or not the operator has entered the predetermined weight range as in the case of weighing while looking at the weight display with one weighing unit like a weighing device such as an upper pan scale. Since each of the plurality of measuring units measures, it is possible to measure efficiently.

  In addition, in order to make the weighing unit an appropriate amount of the weighing unit among the lightweight weighing unit and the excessive amount of weighing unit, the weighing unit that has a useful weight relationship is informed so that the operator can It is possible to recognize a lightweight weighing unit and an excessive amount of weighing unit that have a useful weight relationship, and to adjust the weight of objects to be weighed in both weighing units, and to establish a useful relationship between both weighing units. Using the weight relationship, an appropriate amount of the weighing unit can be efficiently made.

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

  Fig.1 (a) is a top view of the weighing | measuring apparatus based on one Embodiment of this invention, FIG.1 (b) is the side view, FIG.1 (c) is the front view. FIG. 2 is a block diagram showing the configuration of the weighing device of FIG.

  The weighing device of this embodiment is a manual combination balance 1 in which an operator manually supplies and takes out (discharges) an object to be weighed.

  The combination weigher 1 includes a plurality of weighing pans 2 on which objects to be weighed are placed, weight sensors 3 such as load cells that support the weighing pans 2 and detect the weight of the objects to be weighed on the weighing pans 2, A plurality of indicator lamps 4 as a plurality of notification units individually corresponding to the dishes 2, a low box-shaped main body frame 5, and a control unit 6 disposed on one end side in the longitudinal direction of the main body frame 5 are provided. ing.

  The plurality of weighing dishes 2 are arranged in two rows along the longitudinal direction of the main body frame 5. In this embodiment, each row is composed of six weighing dishes 2. Each indicator lamp 4 arranged in the vicinity of each weighing pan 2 is configured using, for example, a three-color LED (light emitting diode).

  The control unit 6 includes a display unit 7 on the front surface and an input unit 8 having input keys. The display unit 7 and the input unit 8 may be integrally configured as a touch panel type.

  The control unit 6 includes a control unit 20 configured by a microcomputer or the like. The control unit 20 has a function as a determination unit 21 and a function as a combination calculation unit 22 as described later. The control unit 20 includes an A / D conversion circuit (not shown) that converts an analog weight signal from the weight sensor 3 into a digital weight signal, a display lamp drive circuit that drives the display lamp 4, and the like.

  The combination weigher 1 of this embodiment performs a combination operation in a normal operation mode in which a single weighing operation mode described later is not set, similarly to a conventional combination weigher.

  That is, in the normal operation mode, when an operator places an object to be weighed on each weighing pan 2, the weight of the object to be weighed on each weighing pan 2 is detected by the weight sensor 3 and given to the control unit 6. The control unit 20 performs a combination calculation based on the weight value of each weighing pan 2. Then, the combination weight, which is the total weight of various combinations of the weights of the objects to be weighed, is in a predetermined weight range, and an appropriate combination of weighing pans 2 that is equal to or closest to the target combination weight is selected, Each indicator lamp 4 in the vicinity of each weighing pan 2 selected for the appropriate amount combination is turned on. As a result, the operator takes out the objects to be weighed from each weighing pan 2 whose indicator lamps 4 are lit, collects them in a container such as one tray, and wraps the container with a plastic film or the like to produce a quantitative pack. .

  In this embodiment, the object to be weighed is difficult to handle in a unit of number such as chopped vegetables such as cut green onions, side dishes such as potato salad, and has an adhesive property. In this case, the operator operates the input unit 8 to set the single weighing operation mode in which no combination calculation is performed, and performs weighing.

  In the setting of the single weighing operation mode, an upper limit weight value and a lower limit weight value that define a predetermined weight range are set, and in this embodiment, a mode for displaying a weighing pan having a complementary relationship described later is also set. .

  In this single weighing operation mode, the control unit 20 of the control unit 6 does not perform the combination calculation, and for each weighing pan 2, the weight of the object to be weighed is an appropriate amount within a predetermined weight range, a light weight less than a predetermined weight range, a predetermined weight. It is determined which amount exceeds the range, and according to the determination result, the corresponding indicator lamp 4 is turned on to notify the operator.

  Since the object to be weighed has adhesiveness, the operator places a container such as a tray on the weighing pan 2, and places the object to be weighed on this container, that is, supplies it. The weight of the container is corrected in advance as the tare weight.

  In this embodiment, the indicator lamp 4 is lit in “green” when the weight of the object to be weighed on the weighing pan 2 is an appropriate amount, “red” when it is light, and “orange” when it is excessive. I have to.

  Here, as an object to be weighed, an example of a basic work procedure of an operator in the single weighing operation mode will be described by taking a cut green onion as an chopped vegetable as an example.

  An operator corrects the weight of a container such as a tray as a tare weight in advance, and places each container on each weighing pan 2 of the combination weigher 1.

  A cut leek is grasped from a storage container (not shown) in which a large amount of cut leek, which is an object to be weighed, is placed on an empty container on each weighing pan 2, that is, supplied. The weight of each weighing pan 2 is detected by the weight sensor 3 and given to the control unit 6. The control unit 20 of the control unit 6 determines whether it is light, appropriate, or excessive with respect to the predetermined weight range based on the weight value of the cut green on each weighing pan 2, and according to the determination result. Each indicator lamp 4 corresponding to each weighing pan 2 is turned on in any one of “red” (light weight), “green” (appropriate amount), and “orange” (excess amount).

  The operator removes a container with an appropriate amount of cut green onion that is lit in “green” (appropriate amount) from the weighing pan 2, places another empty container on the weighing pan 2, and supplies the cut green on this empty container. To do. A container containing an appropriate amount of cut green onions is wrapped with a plastic film or the like by another worker, for example, and becomes a product in a fixed quantity pack.

  The operator can turn the cut green on from the container with the cut weight of the overweight, which is lit in “orange” (overweight), against the container with the cut weight of the low weight that is lit in “red” (light). Grab a part and supply additional, or grab a cut green onion stored in the storage container and supply additional.

  The operator grabs the cut leek of the container with the overweight cut leek that is lit in “orange” (overweight), and contains the underweight cut leek that is lit in “red” (lightweight) as described above. Additional supply to the container, or the cut green onion is returned to the storage container.

  Thus, according to experience and intuition, the operator additionally supplies an appropriate amount of cut green on a container containing cut green onions that are lit in “red” (lightweight), while “ Remove the appropriate amount of cut leek from the container with excess weight of cut onion lit in “orange” (excess amount) and adjust the weight of the object to be lit in “green” (appropriate amount). Containers that are lit in “green” (appropriate amount) are taken out of the weighing pan 2 and wrapped to make a product in a fixed quantity pack, while another container is placed on the empty weighing pan 2 to supply cut green onions. .

  Thus, it can be set as a fixed amount pack containing an appropriate amount of cut leek for each weighing pan 2, that is, for each container, whereby an appropriate amount within a predetermined weight range as in the case of weighing by performing a combination calculation. The time-consuming work of taking out the cut green on other containers neatly so as not to remain in one container among the plurality of containers selected for combination and collecting them in the one container becomes unnecessary. Therefore, it is difficult to handle in a unit of number such as chopped vegetables such as cut green onions and side dishes such as potato salad, and is suitable for production of a quantitative pack of an object to be weighed having adhesion.

  In addition, since the weighing pan 2 that has been individually weighed by the plurality of weighing pans 2 and is in an appropriate amount is notified by the indicator lamp 4, the weight is displayed on one weighing pan like a weighing device such as an upper pan scale. It is not necessary to visually check whether or not the operator himself / herself has entered the predetermined weight range as in the case of weighing while looking at the screen, and the weighing can be efficiently performed with the plurality of weighing pans 2.

  Furthermore, in this embodiment, in order to further increase the efficiency of the weighing work, the following is performed.

  That is, the control unit 20 of the control unit 6 includes the light weight between the weight of the object to be weighed on the light weighing dish 2 and the weight of the object to be weighed on the excessive amount of weighing dish 2. It is determined whether or not a useful weight relationship is established to make the weighing pan 2 and the excessive amount of weighing pan 2 into an appropriate amount of the weighing pan 2, and when the useful weight relationship is established, the weight relationship is established. An operator is notified of the lightweight weighing pan 2 and the excessive weighing pan 2.

  Specifically, the useful weight relationship is such that 1/2 of the added weight obtained by adding the weight of the object to be weighed on the lightweight weighing pan 2 and the weight of the object to be weighed on the excessive weighing pan 2 is a predetermined weight. This is the first useful weight relationship that comes into range.

  When this first useful weight relationship is established, the weight of the object to be weighed in the lightweight weighing pan 2 is x (g), the weight of the object to be weighed in the excessive weighing pan 2 is y (g), When the lower limit weight value is LL (g) and the upper limit weight value is HL (g), the following equation is established.

LL ≦ (x + y) / 2 ≦ HL
When the object to be weighed is a cut leek, for example, if the lower limit weight value LL is 50 g and the upper limit weight value HL is 51.5 g, for example, the predetermined weight range is 50 g or more and 51.5 g or less.

  As described above, the first useful weight relationship is that ½ of the added weight obtained by adding the weight of the object to be weighed in the lightweight weighing pan 2 and the weight of the object to be weighed in the excessive amount of the weighing pan 2 is Since the weight is within the predetermined weight range, the added weight obtained by adding the weight of the object to be weighed on the lightweight weighing pan 2 and the weight of the object to be weighed on the excessive weighing pan 2 is twice the weight of the predetermined weight range. That is, the weight is equivalent to two of the appropriate amount of the weighing pan 2.

  In other words, in the lightweight weighing pan 2 and the excessive weighing pan 2 in which the first useful weight relationship is established, a part of the weighing object of the excessive weighing pan 2 is taken out and transferred to the lightweight weighing pan 2. By changing, both the weighing pans 2 can be made into an appropriate amount of weighing pan 2.

  In this way, by transferring a part of the object to be weighed from the excessive weighing pan 2 to the lightweight weighing pan 2, a set (two) weighing pans in which both weighing pans 2 become appropriate amounts will be described below. , Sometimes referred to as “weighing pan in complementary relationship”.

  In the control unit 20 of the control unit 6, when there is a weighing pan 2 in a complementary relationship in which the first useful weight relationship is established, a corresponding pair (two) of the indicator lamps 4 is flashed and notified. I am doing so.

  In this embodiment, when the display mode for displaying the complementary weighing pan 2 by operating the input unit 8 of the control unit 6 is set, the indicator lamp 4 of the lightweight weighing pan 2 having the complementary relationship is set. , Flashes “red”, and the indicator lamp 4 of the excessive weighing pan 2 flashes “orange”. By setting the single weighing operation mode, the complementary weighing pan 2 may be displayed without setting the display mode for displaying the complementary weighing pan 2.

  Since the operator can recognize the two weighing pans 2 in the complementary relationship, a part of the cutting green on the container of the weighing pan 2 blinking in “orange” (excess amount) becomes an appropriate amount. Is taken out and transferred to the container of the weighing pan 2 blinking in “red” (light weight). As a result, the weight of the object to be weighed in the lightweight weighing pan 2 flashing in “red” and the weight of the object in the excessive weighing pan 2 flashing in “orange” both become appropriate amounts, The indicator lamps 4 of any weighing pan 2 are lit in “green”.

  In this way, the operator moves the appropriate amount of cut green on the weighing pan 2 to the lightweight weighing pan 2 by flashing the set of indicator lamps 4 of the weighing pan 2 in a complementary relationship. As a result, the weights of the cut green on the two weighing pans 2 can both be made appropriate, and the efficiency of the weighing operation is further improved.

  Furthermore, in this embodiment, when there are a plurality of sets of weighing pans 2 in a complementary relationship, the display mode can be selected. That is, when the complementary relationship 1 set display mode for displaying only one set of complementary relationships is set by operating the input unit 8, there is a position closest to the distance among the plurality of sets of weighing pans 2 in the complementary relationship. A set of indicator lamps 4 corresponding to the complementary weighing pans 2 is blinked. As a result, the operator grasps an appropriate amount of the cut green on the container of the weighing pan 2 blinking in “orange”, and the weighing pan 2 blinking in “red” in a position close to it. What is necessary is just to transfer to a container, and work can be performed efficiently.

  In addition, the indicator lamp 4 is turned off when the object to be weighed in the complementary weighing pan 2 in the closest relationship among the plurality of sets of weighing pans 2 in the complementary relationship becomes an appropriate amount and the container is taken out of the weighing pan 2. Then, among a plurality of sets of weighing pans 2 in a complementary relationship, a set of indicator lights 4 in a complementary relationship in the next closest position is flashed, and similarly, a weighing pan 2 in a complementary relationship is displayed. Blinks until it disappears.

  If there are a plurality of sets of weighing pans 2 in a complementary relationship, and the complementary relationship 1 set display mode is not set, all of the indicator lamps 4 of the plurality of sets of weighing pans 2 in a complementary relationship are blinked. . In this case, the blinking period is different for each group, and the blinking period of the same group is the same. For example, when there are two sets of weighing pans 2 in a complementary relationship, the blinking cycle of one set of indicator lamps 4 is shortened, and the blinking cycle of the other set of indicator lamps 4 is increased.

  As a result, the operator takes out an appropriate amount of cut green on the weighing pan 2 of the indicator lamp 4 with “orange” (excessive amount) and a short (or long) blinking cycle, and “red” (light weight) with the blinking cycle. What is necessary is just to transfer to the weighing pan 2 of the short (or long) indicator lamp 4, and a weighing operation can be performed efficiently.

  3 and 4 are flowcharts for explaining the operation in the single metering operation mode of the above embodiment.

  First, it is determined whether or not the power is turned on (step S1). When the power is turned on, initialization processing, specifically, the control unit 20 of the control unit 6 is initialized, and the indicator lamps 4 are turned on in order. Then, the user can easily check whether the combination weigher 1 has failed or not, and when the combination weigher 1 becomes stable, zero correction is automatically performed (step S2).

  The operator operates the input unit 8 to set the single weighing operation mode, and displays a lower limit weight value that defines a predetermined weight range, an upper limit weight value, a display mode that displays a weighing pan in a complementary relationship, and the like. Set (step S3).

  Next, a variable k for repeating the processing for each weighing pan 2 is set to an initial value “1” (step S4), and a weighing value of the weighing pan 2 (k) corresponding to the variable k is read (step S5). A stability determination process of the measurement value of the weighing pan 2 (k) is performed (step S6). In this stability determination process, for example, it is determined that the measurement value is stable when the measured value has not changed for a certain period of time. By this stability determination process, it is determined whether or not the measurement value of the weighing pan 2 (k) is stable (step S7).

  When it is determined in step S7 that the measurement value is stable, it is determined whether or not the zero correction key is turned on (step S8). When the zero correction key is turned on, the measurement value can be corrected to zero. It is determined whether or not it is within the zero point correction range (step S13). If it is within the zero point correction range, zero point correction processing of the weighing pan 2 (k) is performed and the process proceeds to step S12 (step S15). Assuming that there is some abnormality that the zero point is greatly deviated, the zero correction error display of the weighing pan 2 (k) is performed and the process proceeds to step S12 (step S19).

  If the zero correction key is not turned on in step S8, it is determined whether the tare key is turned on (step S9). If the tare key is turned on, the tare weight of the weighing pan 2 (k) is tared. The process is performed and the process proceeds to step S12 (step S16).

  In step S9, if the tare key is not turned on, it is determined whether or not the measured value is equal to or higher than the loading detection point (step S10). If it is not equal to or higher than the loading detection point, the weighing pan 2 (k) is loaded. Moves to step S11 assuming that there is no object to be weighed, turns off the indicator lamp 4 of the weighing pan 2 (k), and moves to step S12.

  In step S10, when the measured value is equal to or greater than the loading detection point, it is determined whether the measured value is less than the lower limit weight value, that is, whether the weight value is light (step S17). If there is, the indicator lamp 4 is lit in “red” indicating that the object to be weighed on the weighing pan 2 (k) is light, and the process proceeds to step S12 (step S18). In step S17, when it is not less than the lower limit value, it is determined whether or not the measured value is not less than the lower limit value and not more than the upper limit value, that is, an appropriate amount within a predetermined weight range (step S20). Sometimes, the indicator lamp 4 is turned on with “green” indicating that the object to be weighed in the weighing pan 2 (k) is an appropriate amount, and the process proceeds to step S12 (step S21). In step S20, when the weight is not within the predetermined weight range, the indicator lamp 4 is lit in “orange” indicating that the object to be weighed in the weighing pan 2 (k) is excessive, and the process proceeds to step S12 (step S22). ).

  In step S12, the variable k is incremented and the process proceeds to step S13. In step S13, it is determined whether or not the variable k has reached the total number (n + 1) of the weighing pans 2. If not, the next weighing pan is reached. Returning to step S5 for the process of No. 2 and when it reaches, the process moves to step S23 of FIG.

  In step S23, it is determined whether or not the display mode for displaying the complementary weighing pan is set. If the display mode is for displaying the complementary weighing pan, the display of each weighing pan 2 is as described above. Based on the weight of the weighing object, the upper limit weight value, and the lower limit weight value, a process for searching for the complementary weighing pan 2 is performed (step S24), and it is determined whether there is a set of the complementary weighing pan 2 or not. (Step S25), when there is no complementary weighing pan 2 set, the process returns to Step S5 of FIG.

  In step S25, when there is a set of complementary weighing pans 2, it is determined whether there are a plurality of sets of complementary weighing pans 2 (step S26). A set of indicator lamps 4 corresponding to the set of weighing pans 2 blinks in “orange” and “red”, respectively, and the process returns to step S5 in FIG. 3 (step S30).

  If there are a plurality of sets of complementary weighing pans 2 in step S26, it is determined whether or not a display mode for displaying one set of complementary weighing pans is set (step S27). When the display mode for displaying one set is set, the set of weighing pans 2 in which the excess weighing pan 2 and the lightweight weighing pan 2 are closest to each other among the plurality of complementary weighing pans 2 are set. The set of indicator lights 4 corresponding to is blinked in “orange” and “red”, respectively, and the process returns to step S5 in FIG. 3 (step S28).

  In step S27, when the display mode for displaying one set of complementary weighing pans is not set, a corresponding set of indicator lamps 4 is set for each of a plurality of sets of complementary weighing pans 2 with a flashing cycle. Differently, it blinks in “orange” and “red”, and the process returns to step S5 in FIG.

  FIG. 5 (a) is a plan view of a weighing device 13 according to another embodiment of the present invention, FIG. 5 (b) is a side view thereof, and FIG. 6 is a view of the weighing device 13 of FIG. It is a block diagram which shows a structure, and attaches | subjects the same referential mark to the part corresponding to the said embodiment.

  The weighing device 13 of this embodiment includes a manual combination balance 1a and an upper pan balance 12 as an external balance.

  The combination weigher 1a has the same function as the combination weigher 1 of the above-described embodiment, can perform combination calculation in the same manner as a conventional combination weigher, and can execute the above-described single weighing operation mode. Furthermore, in this combination weigher 1a, as will be described later, it is possible to execute a linked single weighing operation mode in which a single weighing operation linked to an upper pan scale 12 which is an external balance is performed.

  The upper pan scale 12 includes a weighing pan 14 on which an object to be weighed is placed, a weight sensor 15 that supports the weighing pan 14 and includes a load cell for weighing the object to be weighed on the weighing pan 14, and a weight sensor. And a control device 16 that acquires the weight of the object weighed by 15 and displays the weight on a display panel (not shown).

  The control device 16 of the upper balance 12 is configured to be able to communicate with the control unit 20a of the control unit 6a of the combination weigher 1a wirelessly or by wire, and measures the weight of the object to be weighed placed on the weighing pan 14. Each time the stable measured value changes, the measured value is transmitted to the control unit 20 of the control unit 6a of the combination weigher 1a.

  In the combination weigher 1a of this embodiment, in the same way as in the above embodiment, the object to be weighed is difficult to handle in a unit of number, such as a cut green onion, and has an adhesive property. In this case, by operating the input unit 8 of the control unit 6a, a linked single weighing operation mode that is a single weighing operation mode linked to an external scale can be set. Even in this linked single lightweight operation mode, the same operation as the single weighing operation mode similar to the above embodiment can be performed.

  In this linked single lightweight operation mode, a storage container (not shown) storing a large amount of objects to be weighed, such as cut green onions, supplied to the weighing pan 2 of the combination weigher 1a is mounted on the upper pan balance 12 which is an external balance. The upper pan scale 12 corrects the weight of the storage container itself as the tare weight, measures the weight of the stored cut leek, and transmits the measured weight value to the control unit 6a of the combination weigher 1a.

  In the control unit 20a of the control unit 6a, when the weight value decreases based on the weight value transmitted from the upper pan scale 12, the reduced weight is calculated by the weight of the cut green onion taken out from the storage container by the operator. Therefore, it is calculated as the supply weight of the cut leek supplied to the weighing pan 2.

  The control unit 20 of the control unit 6a is provided between the weight of the cut green onion that is removed from the storage container and supplied to the weighing pan 2, and the weight of the cut green on the lightweight weighing pan 2 among the plurality of weighing pans 2. In addition, it is determined whether or not the second useful weight relationship useful for making the lightweight weighing pan 2 an appropriate amount of the weighing pan 2 is established, and when the second useful weight relationship is established, The lightweight weighing pan 2 is notified to the operator.

  Specifically, the second useful weight relationship is obtained by adding the weight of the cut green onion taken out from the storage container and supplied to the weighing pan 2 and the weight of the cut green on the lightweight weighing pan 2. The added weight is in a predetermined weight range, that is, a weight relationship that is an appropriate amount.

  In other words, the lightweight weighing pan 2 that satisfies the second useful weight relationship becomes an appropriate amount of the weighing pan 2 by additionally supplying the weighing pan 2 with the cut green onions taken out from the storage container.

  In this embodiment, when the operator takes out the cut green onion from the storage container and there is a lightweight weighing pan 2 that satisfies the second useful weight relationship, an indicator lamp corresponding to the lightweight weighing pan 2 is provided. 4 is switched from lighting of “red” indicating light weight to lighting of “blue” indicating the supply destination of the cut green onions taken out from the storage container.

  In this way, when the operator takes out the cut green onion from the storage container, when there is a lightweight weighing pan 2 that satisfies the second useful weight relationship, the indicator light 4 of the lightweight weighing pan 2 is displayed as “red “(Light)” is switched to “Blue” indicating the supply destination, so that the operator additionally supplies the cut green onion to the lightweight weighing pan 2 lit in “Blue”. As a result, the lightweight weighing pan 2 becomes an appropriate amount, and the indicator lamp 4 is switched from “blue” to “green” (appropriate amount).

  The operator takes out the container from the weighing pan 2 corresponding to the indicator light 4 switched to the lighting of “green” (appropriate amount) and wraps it to make a product in a fixed quantity pack. To supply cut green onions.

  As described above, when the operator takes out the cut green onion from the storage container, when there is a lightweight weighing pan 2 that becomes an appropriate amount by additionally supplying the cut green onion, the indicator light 4 of the weighing pan 2 is , The lighting is switched from “red” (light weight) to “blue”, so that the operator can supply an appropriate amount of the cut green onion by additionally supplying it to the weighing pan 2 of the indicator light 4 lit in “blue”. The weighing pan 2 can be used.

  Further, in this embodiment, in the display mode for displaying the above-described complementary weighing pan, the control unit 20a of the control unit 6a takes the supply weight of the cut leek taken out from the storage container and supplied to the weighing pan 2; A third useful utility for making the two lightweight weighing parts into an appropriate amount of weighing pan 2 between the weights of the cut green onions of the two lightweight weighing pans 2. When the third useful weight relationship is established, the operator is notified of two lightweight weighing pans 2 that satisfy the third useful weight relationship.

  Specifically, the third useful weight relationship includes the supply weight of the cut green onions taken out from the storage container and supplied to the weighing pan 2, and the weights of the cut green onions of the two lightweight weighing pans 2. A weight relationship in which ½ of the added weight obtained by adding is a predetermined weight range.

  In this third useful weight relationship, when the cut leek taken out from the storage container is additionally supplied to one of the two lightweight weighing pans 2, this one weighing pan 2 is overloaded. 1/2 of the added weight obtained by adding the weight of the cut green onion of the excess weighing pan 2 and the weight of the cut green on the other weighing pan 2 of the two lightweight weighing pans 2; The two weighing pans 2 have a weight within a predetermined weight range, that is, the weighing pans 2 are in the complementary relationship.

  In this embodiment, when the operator takes out the cut green onion from the storage container and there are two light weight weighing pans 2 that satisfy the third useful weight relationship, the two light weight weighing pans 2 The corresponding two indicator lamps 4 are switched from lighting “red” indicating light weight to lighting “blue” indicating the supply destination of the cut green onions taken out from the storage container.

  As described above, when the operator takes out the cut green onion from the storage container, when there are two lightweight weighing dishes 2 that satisfy the third useful weight relationship, the indicator lights 4 of the two lightweight weighing dishes 2 are provided. However, since the lighting of “red” (light weight) is switched to the lighting of “blue” indicating the supply destination, the operator can take out the cut green onion with two lightweight weighing pans that are lit in “blue”. 2 is additionally supplied to one weighing pan 2.

  As a result, one weighing pan 2 becomes excessive, and the one weighing pan 2 and the other lightweight weighing pan 2 become a weighing pan 2 in a complementary relationship. Accordingly, the indicator lamp 4 of the one weighing pan 2 starts blinking with “orange” (excessive amount), and the indicator lamp 4 of the other weighing pan 2 starts blinking with red “light”.

  Thus, as in the above embodiment, the operator can set an appropriate amount of the cut green on the weighing pan 2 blinking in “orange” (excess amount) and a weighing pan blinking in “red” (light weight). 2 can be used together to make an appropriate amount of weighing pan 2.

  By removing the cut green onion from the storage container in this way and additionally supplying it to the “blue” weighing pan 2, the complementary weighing pan 2 is obtained, and the weight of the cut green on the complementary weighing pan is adjusted. Since two appropriate amounts of the weighing pan 2 can be obtained, the efficiency of the weighing operation is further improved.

  In the above, when the operator takes out the cut green onion from the storage container and there are two lightweight weighing pans 2 that satisfy the third useful weight relationship, the indicators of the two lightweight weighing pans 2 are displayed. 4 is switched to “blue” lighting, but only one of the indicator lamps 4 may be switched to “blue” lighting.
