前記サンプリング装置36は、集積用ホッパー２の側面に内外を貫通する貫通孔（図示せず）を形成すると共に、該貫通孔を開閉する板状のシャッター55を集積用ホッパー２の側面にスライド自在に設けると共に、該シャッター55を第４の電磁石装置56の進退作動軸57に接続して、第４の電磁石装置56の作動により貫通孔を開き、そして集積用ホッパー２に集積された籾の一部をパイプ58を介して取り出し、一対の柱体１の間に架設した横杆59に回動自在に設けたターンテーブル60に載置したサンプル用容器61に収容できるようになっている。 The sampling device 36 forms a through hole (not shown) penetrating the inside and outside of the side surface of the stacking hopper 2, and a plate-like shutter 55 that opens and closes the through hole is slidable on the side surface of the stacking hopper 2. The shutter 55 is connected to the advance / retreat operating shaft 57 of the fourth electromagnet device 56, the through hole is opened by the operation of the fourth electromagnet device 56, and the scissors integrated in the accumulation hopper 2 The portion is taken out via a pipe 58 and can be accommodated in a sample container 61 placed on a turntable 60 that is rotatably provided on a horizontal bar 59 installed between a pair of pillars 1.

さらに、集積用ホッパー２の後部にバケットコンベア等の縦向きコンベア62を設ける。この縦向きコンベア62は、その下部に投入口62Ａを設けると共に、上部に集積用ホッパー２の上部開口に臨んで排出口62Ｂが設けられている。 Further, a vertical conveyor 62 such as a bucket conveyor is provided at the rear of the stacking hopper 2. The vertical conveyor 62 is provided with an input port 62A at the lower portion thereof, and is provided with an outlet port 62B at the upper portion thereof so as to face the upper opening of the stacking hopper 2.

また、制御装置30には第１及び第２の電磁石装置８，９、ロードセル18、第３の電磁石装置21、第４の電磁石装置56が接続されている。そして、制御装置30は小分けした状態の重量を積算して所定の目標総重量になったときに集積用ホッパー２からの排出を停止するようになっている。 The control device 30 is connected to the first and second electromagnet devices 8 and 9, the load cell 18, the third electromagnet device 21, and the fourth electromagnet device 56. Then, the control device 30 is configured to stop discharging from the stacking hopper 2 when the subdivided weights are integrated to reach a predetermined target total weight.

次に前記構成についてその作用を説明する。例えば籾を投入口62へ投入することで、縦向きコンベア61により上昇せしめて、排出口62Ｂから集積用ホッパー２へ投入する。そして、オン・オフボタン42により電源を入れる。そして、計量を始める。尚、実際の計量においては目標総重量を１０００ｋｇとする場合が一般的であるが、実施例では目標総重量を１００ｋｇとして説明する。図９に示すように目標総重量１００ｋｇを３０ｋｇづつ小分けして計量するときは、まず重量設定ボタン14を押圧し、次にテンキーボタン47で目標総重量１００ｋｇに対応する数字１００を入力し、さらに設定ボタン49を押圧して入力を確定させる。そして、定量ボタン50を押圧し、テンキー47で小分け目標重量３０ｋｇに対応する数字３０を入力し、さらに設定ボタン49を押圧して入力を確定させる。次に、４回目の計量に当たる最終計量時に供給を小供給（小出し）に切り換える、すなわち第１の開閉板７を全開と全閉の途中位置に設定できるようにする。その際の設定重量、例えばロードセル18が６ｋｇを検知したときにそのような作動がなされるようにするには、小供給目標重量６ｋｇに対応する数字６を入力し、設定ボタン49を押圧して入力を確定させる。 Next, the operation of the above configuration will be described. For example, when the straw is introduced into the insertion port 62, it is lifted by the vertical conveyor 61 and is introduced into the stacking hopper 2 from the discharge port 62B. Then, the power is turned on by the on / off button 42. Then start weighing. In the actual measurement, the target total weight is generally set to 1000 kg. However, in the embodiment, the target total weight is assumed to be 100 kg. As shown in FIG. 9, when the target total weight 100 kg is subdivided and weighed by 30 kg, the weight setting button 14 is first pressed, and then the number 100 corresponding to the target total weight 100 kg is input with the numeric keypad 47, Press the setting button 49 to confirm the input. Then, the fixed amount button 50 is pressed, the number 30 corresponding to the subdivided target weight 30 kg is input with the numeric keypad 47, and the setting button 49 is further pressed to confirm the input. Next, at the final measurement corresponding to the fourth measurement, the supply is switched to the small supply (small delivery), that is, the first opening / closing plate 7 can be set to the halfway position between full open and full close. In order to perform such an operation when the set weight at that time, for example, the load cell 18 detects 6 kg, the number 6 corresponding to the small supply target weight 6 kg is input, and the setting button 49 is pressed. Confirm the input.

このような入力操作により、制御装置30は目標総重量が１００ｋｇで３０ｋｇづつの小分け計量を３回繰り返し、最終の第４回目の計量では小供給（小出し）設定目標値である６ｋｇを計量すると小供給（小出し）、すなわち第１の開閉板７を全開より小さく開成するように切り換えし、積算重量が１００ｋｇを計量して終了することを計算する。したがって、予め図９に示すように第２の落下口15の下方に、袋24及びスタンド25に代えて１００ｋｇの籾が収容可能な袋などの容器（図示せず）を設置した後に、制御装置30を作動する。尚、図９において縦軸は計量重量を示しており、横軸は計量工程の回数を示し、そして表中実線は各計量工程（各バッジ）での計量重量、一点鎖線は積算（累積或いは集計）重量を示している。第１回目の計量では、予め第２の開閉板20は閉成しており、そして第１の開閉板７が全開することにより集積用ホッパー２の籾は第１の落下口５より計量ホッパー14に落下収容される。この計量ホッパー14への重量をロードセル18は検知しており、３０ｋｇを検知すると制御装置30は第１の電磁石装置８及び第２の電磁石装置９を非通電状態として全閉状態とする。しかしながら、３０ｋｇを検知した時と第一の開閉板７が全閉する時は一致しないので、すなわち両者にはタイムラグが生じるので、第１の落下口５より計量ホッパー14へは３０ｋｇを超えた、例えば３１ｋｇの籾が収容される。同時にその重量は積算重量表示部31、測定重量表示部32に表示される。そして第２の開閉板20が全開して３１ｋｇの籾が第１回目の計量として前記１００ｋｇ用の容器に収容される。所定時間後に第２の開閉板20が全閉状態となり、再び第１の開閉板７が全開すると第１の落下口５より計量ホッパー14へは３０ｋｇを超えた、例えば３１ｋｇの籾が再び収容されて第１の開閉板７は全閉状態となる。この第２回目の計量、すなわちによって積算重量表示部31には例えば６２ｋｇが表示され、測定重量表示部32には３１ｋｇが表示される。 By such an input operation, the control device 30 repeats the sub-weighing of 30 kg each with a target total weight of 100 kg three times. In the final fourth measurement, the small supply (small dispensing) target value 6 kg is weighed. Supply (small delivery), that is, the first opening / closing plate 7 is switched so as to be opened smaller than the full opening, and it is calculated that the integrated weight is measured by measuring 100 kg. Therefore, after a container (not shown) such as a bag capable of accommodating 100 kg of bags instead of the bag 24 and the stand 25 is previously installed below the second drop port 15 as shown in FIG. Operate 30. In FIG. 9, the vertical axis represents the weighing weight, the horizontal axis represents the number of weighing processes, the solid line in the table represents the weighing weight in each weighing process (each badge), and the alternate long and short dash line represents the accumulated (accumulated or totaled) ) Indicates weight. In the first weighing, the second opening / closing plate 20 is closed in advance, and when the first opening / closing plate 7 is fully opened, the trap of the stacking hopper 2 is transferred from the first dropping port 5 to the weighing hopper 14. Fall accommodated. The load cell 18 detects the weight to the weighing hopper 14, and when 30 kg is detected, the control device 30 puts the first electromagnet device 8 and the second electromagnet device 9 in a non-energized state and makes them fully closed. However, when 30 kg is detected and when the first opening / closing plate 7 is fully closed, they do not coincide with each other, that is, a time lag occurs between them, so that the weighing hopper 14 has exceeded 30 kg from the first drop port 5. For example, 31 kg of straw is accommodated. At the same time, the weight is displayed on the integrated weight display unit 31 and the measured weight display unit 32. Then, the second opening / closing plate 20 is fully opened, and 31 kg of straw is accommodated in the 100 kg container as the first measurement. After a predetermined time, when the second opening / closing plate 20 is fully closed and the first opening / closing plate 7 is fully opened again, the weighing hopper 14 from the first dropping port 5 is again accommodated with, for example, 31 kg of soot. Thus, the first opening / closing plate 7 is fully closed. For example, 62 kg is displayed on the integrated weight display unit 31 and 31 kg is displayed on the measured weight display unit 32 due to the second measurement, that is, the integrated weight display unit 31.

そして、第２の開閉板20が全開して３１ｋｇの籾が第２回目の計量として前記１００ｋｇ用の容器に収容される。同様に第３回目の計量が行なわれ、前記１００ｋｇ用の容器には例えば９３ｋｇの籾が収容される。最終計量の第４回目の計量では予め第２の開閉板20は閉成しており、そして第１の開閉板７が全開することにより集積用ホッパー２の籾は第１の落下口５より計量ホッパー14に落下収容される。この計量ホッパー14への重量をロードセル18は検知しており、予め設定した小供給（小出し）設定目標値である６ｋｇを検知すると、制御装置30は上述のように第１の電磁石装置８を通電したまま第１の連結杆12を引き、第２の電磁石装置９を非通電として第２の連結杆13を押して、この結果開閉板７を全開と全閉状態の中間とする。これにより、第１の落下口５より計量ホッパー14に落下収容する単位時間当たりの量は小さくなり、小供給（小出し）状態となる。そして、この小供給（小出し）状態でロードセル18が７ｋｇを検知すると、すなわち積算重量で１００ｋｇを検知すると、制御装置30により第１の開閉板７が全閉すると共に、第２の開閉板20が全開して残りの７ｋｇが前記容器に収容されて目標総重量の１００ｋｇの計量を終了する。 Then, the second opening / closing plate 20 is fully opened and 31 kg of straw is accommodated in the 100 kg container as the second measurement. Similarly, the third weighing is performed, and for example, 93 kg of soot is accommodated in the 100 kg container. In the fourth measurement of the final measurement, the second opening / closing plate 20 is closed in advance, and when the first opening / closing plate 7 is fully opened, the trap of the stacking hopper 2 is measured from the first drop port 5. Dropped into the hopper 14. The load cell 18 detects the weight to the weighing hopper 14, and when detecting 6 kg which is a preset target value for small supply (dispensing), the control device 30 energizes the first electromagnet device 8 as described above. The first connecting rod 12 is pulled while the second electromagnet device 9 is de-energized and the second connecting rod 13 is pushed. As a result, the open / close plate 7 is placed between the fully open state and the fully closed state. As a result, the amount per unit time that is dropped and accommodated in the weighing hopper 14 from the first drop port 5 is reduced, and a small supply (small delivery) state is established. When the load cell 18 detects 7 kg in this small supply (small delivery) state, that is, when 100 kg is detected in the integrated weight, the first opening / closing plate 7 is fully closed by the control device 30 and the second opening / closing plate 20 is The remaining 7 kg is fully opened and the weighing of 100 kg of the target total weight is completed.

一方、集積用ホッパー２より籾を例えば３０ｋｇ袋詰めするような場合は、図２に示すようにスタンド25に袋24を予めセットしておく。次に制御装置30の重量設定ボタン40を押圧し、テンキー47で目標重量３０ｋｇに対応する数字３０を入力し、さらに設定ボタン49を押圧して入力を確定させる。次に定量ボタン50を押圧し、テンキー47で目標重量３０ｋｇに対応する数字３０を入力し、さらに設定ボタン49を押圧して入力を確定させる。次に小供給ボタン51を押圧して、計量時に供給を小供給（小出し）に切り換える、すなわち第１の開閉板７を全開と全閉の途中位置に設定できるようにする。その際の設定量、例えばロードセル18が２８ｋｇを検知したときにそのような作動がなされるようにするには、小供給目標重量２８ｋｇに対応する数字２８を入力し、設定ボタン49を押圧して入力を確定させる。 On the other hand, when bagging, for example, 30 kg of bag from the accumulation hopper 2, the bag 24 is set in advance on the stand 25 as shown in FIG. Next, the weight setting button 40 of the control device 30 is pressed, the number 30 corresponding to the target weight 30 kg is input with the numeric keypad 47, and the setting button 49 is further pressed to confirm the input. Next, the fixed amount button 50 is pressed, the number 30 corresponding to the target weight 30 kg is input with the numeric keypad 47, and the setting button 49 is further pressed to confirm the input. Next, the small supply button 51 is pressed so that the supply is switched to small supply (small dispensing) at the time of weighing, that is, the first opening / closing plate 7 can be set to a halfway position between full open and full close. In order to make such an operation when the set amount at that time, for example, the load cell 18 detects 28 kg, the number 28 corresponding to the small supply target weight 28 kg is input, and the setting button 49 is pressed. Confirm the input.

このような入力操作により、制御装置30は目標重量を３０ｋｇを１回とし、そして図１０R>０に示すようにロードセル18が２８ｋｇを検知するまでは第１の開閉板７を全開として籾を第２の開閉板20が全閉状態の計量ホッパー14に収容し、そしてロードセル18が２８ｋｇを検知したときに、第１の開閉板７を全開と全閉の途中位置に設定して小供給（小出し）状態として籾を継続して計量ホッパー14に収容する。この後ロードセル18が３０を検知すると第１の開閉板７を全閉とする。その後、第２の開閉板20を全開として籾を袋24に収容するものである。 By such an input operation, the control device 30 sets the target weight to 30 kg once, and the first opening / closing plate 7 is fully opened until the load cell 18 detects 28 kg as shown in FIG. When the opening / closing plate 2 is accommodated in the weighing hopper 14 in the fully closed state and the load cell 18 detects 28 kg, the first opening / closing plate 7 is set to the halfway position between full opening and full closing, and small supply (small dispensing) ) Continue to fill the weighing hopper 14 with the bag as a state. Thereafter, when the load cell 18 detects 30, the first opening / closing plate 7 is fully closed. After that, the bag is accommodated in the bag 24 with the second opening / closing plate 20 fully opened.

When the value approaches the target total weight, the first opening / closing body 7 is opened and held at an intermediate position after being fully opened, and then fully closed, so that the first to third times, for example, 30 kg In the sub-measurement, the first opening / closing plate 7 repeats full open and fully closed for measurement, so that the measurement speed can be increased. On the other hand, in the fourth measurement, the first open / close plate is used. After measuring with 7 fully open, when the preset small supply (small delivery) set target value is reached, the opening of the first opening / closing plate 7 is reduced to reduce the discharge per unit time and adjust the measurement. While measuring the target total weight Since the adjustment by the first opening and closing plate 7 at the time of measurement was made at the time of the final measurement, there was no time loss associated with the adjustment by the first opening and closing plate 7 except for the final turn. The total time required for weighing can be shortened. For example, when only 30 kg is weighed, the adjustment by the first opening / closing plate 7 can be performed at the time of weighing. It is possible to accurately measure in

しかも、前記積算値が例えば１００ｋｇとした前記目標総重量に近づき前記第１の開閉板７は全開の後、中間位置で開成保持され、この後全閉する工程は第４回目の最終工程でとすることにより、計量が前記目標総重量に達するまでには小供給（小出し）を１回のみで済ますようになるので、第１の開閉板７による調整に共なう回数を最終工程の１回のみですますことができ、計量に伴う時間の総時間を最短時間とすることができる。 Moreover, when the integrated value approaches the target total weight, for example, 100 kg, the first opening / closing plate 7 is opened and held at an intermediate position after being fully opened, and the process of fully closing thereafter is the fourth final process. As a result, only one small supply (small dispensing) is required until the weighing reaches the target total weight. Therefore, the number of adjustments by the first opening / closing plate 7 is set to one time of the final process. The total time required for weighing can be made the shortest time.

しかも、実施例では制御装置30において、目標総重量、小分け重量目標値、小供給（小出し）設定目標値を夫々自由に設定することができるので、いかなる計量にも対処することができる。また、その操作は積算（累積又は集計）計量のときも、１回（１バッジ）のときの計量も、いずれも重量設定ボタン40、定量ボタン50、及び小供給ボタン51による同一であるので、操作性も優れる。 In addition, in the embodiment, since the target total weight, the subdivided weight target value, and the small supply (dispensing) set target value can be set freely in the control device 30, any weighing can be dealt with. In addition, the operation is the same with the weight setting button 40, the fixed amount button 50, and the small supply button 51 for both the integration (cumulative or total) measurement and the measurement for one time (one badge).
