Abstract
Description
本発明は、被計量物、特に食品を計量するための計量装置に関するものである。 The present invention relates to a weighing device for weighing an object to be weighed, particularly food.
従来、ホッパー等から供給されバケット内に貯留された食品等の被計量物を計量し、所定重量となった被計量物をバケットからシュートを介して排出する計量装置が存在する。ここで、高付着性の被計量物がバケット内壁面に付着することを防止するために、例えば特許文献１にはホッパー（バケット）内壁面の必要箇所に波板を装着可能な計量装置について開示されている。また、特許文献２には、ホッパー（バケット）内壁面に、両側部及び下部を切断した切断箇所を上部に対して隆起させた傾斜突起部を複数列連続して設けたホッパー（バケット）について開示されている。 Conventionally, there is a weighing device that weighs a weighted object such as food supplied from a hopper or the like and stored in a bucket, and discharges the weighted object having a predetermined weight from the bucket through a chute. Here, in order to prevent a highly adhesive object to be weighed from adhering to the inner wall surface of the bucket, for example, Patent Document 1 discloses a weighing device capable of mounting a corrugated sheet at a required position on the inner wall surface of a hopper (bucket). Has been done. Further, Patent Document 2 discloses a hopper (bucket) in which a plurality of rows of inclined protrusions are continuously provided on the inner wall surface of the hopper (bucket) so that the cut portions cut on both sides and the lower portion are raised with respect to the upper portion. Has been done.
ところで、特許文献１及び２記載の波板やホッパーを計量装置に用いた場合であっても、被計量物とバケット内壁面との接触面積が十分に小さいとはいえず、高付着性の被計量物がバケット内部に付着することを十分に防止することができなかった。また、計量後にバケットを振動させて被計量物を振り落とすことにより被計量物の付着防止を図ることもできるが、次の計量時においてバケットの振動がおさまるまで待機しなければならず、自動計量を迅速に連続して行うことができなかった。また、バケット内壁面をフッ素コーティング等することにより被計量物の付着防止を図ることもできるが、連続使用によりコーティングが剥離し、食品衛生上、および食品安全上問題があった。 By the way, even when the corrugated sheet or hopper described in Patent Documents 1 and 2 is used in the weighing device, it cannot be said that the contact area between the object to be measured and the inner wall surface of the bucket is sufficiently small, and the subject has high adhesion. It was not possible to sufficiently prevent the weight from adhering to the inside of the bucket. It is also possible to prevent the object to be measured from adhering by vibrating the bucket after weighing to shake off the object to be measured, but at the time of the next measurement, it is necessary to wait until the vibration of the bucket subsides, and automatic weighing is performed. Could not be done quickly and continuously. Further, although it is possible to prevent the object to be measured from adhering by coating the inner wall surface of the bucket with fluorine or the like, the coating is peeled off by continuous use, which causes problems in food hygiene and food safety.

Further, the stirring blade 8 is provided at the discharge port of the upper hopper 6, and as shown by the arrow A1 in FIG. 1, the food 4 in the upper hopper 6 is stirred by rotating and conveyed to the lower hopper 10. ..
下ホッパー１０は、スクリューフィーダー１２を介して食品４をバケット１６に供給する。下ホッパー１０は対向する一方の二側部（図１の紙面前後に位置する二側部）が逆台形状及び対向する他方の二側部（図１の紙面左右に位置する二側部）が矩形状の有底四角筒であって、下ホッパー１０の上部には上ホッパー６から搬送された食品４を下ホッパー１０内に供給する供給口が設けられている。また、下ホッパー１０の一側部（図１の紙面右に位置する側部）の下部には下ホッパー１０内の食品４を下流側のスクリューフィーダー１２に向けて排出する排出口が設けられている。スクリューフィーダー１２は、図示しないモーター等を駆動させることにより回転可能に構成されている。また、スクリューフィーダー１２は、下ホッパー１０の排出口に設けられており、図１の矢印Ａ２に示すように回転することにより下ホッパー１０内の食品４を供給口から排出口に向けてスクリューフィーダー１２内を移動し、図１の矢印Ａ４に示すようにスクリューフィーダー１２の排出口から排出され、バケット１６の受入口からバケット１６内に供給される。 The lower hopper 10 supplies the food 4 to the bucket 16 via the screw feeder 12. The lower hopper 10 has an inverted trapezoidal shape on one side facing each other (two sides located on the front and back of the paper surface in FIG. 1) and two side portions facing each other (two sides located on the left and right sides of the paper surface in FIG. 1). It is a rectangular bottomed square cylinder, and a supply port for supplying food 4 conveyed from the upper hopper 6 into the lower hopper 10 is provided above the lower hopper 10. Further, a discharge port for discharging the food 4 in the lower hopper 10 toward the screw feeder 12 on the downstream side is provided in the lower part of one side portion (the side portion located on the right side of the paper surface in FIG. 1) of the lower hopper 10. There is. The screw feeder 12 is configured to be rotatable by driving a motor or the like (not shown). Further, the screw feeder 12 is provided at the discharge port of the lower hopper 10, and by rotating as shown by the arrow A2 in FIG. 1, the food 4 in the lower hopper 10 is directed from the supply port to the discharge port. It moves in 12, is discharged from the discharge port of the screw feeder 12 as shown by arrow A4 in FIG. 1, and is supplied into the bucket 16 from the receiving port of the bucket 16.
バケット１６は、計量部１８により計量する食品４を受け入れる容器である。図２は、バケット１６の構成を示す斜視図である。バケット１６は、図２に示すように、対向する一方の二側部（図１の紙面前後に位置する二側部）１６ａ，１６ｂが逆三角形状及び対向する他方の二側部（図１の紙面左右に位置する二側部）１６ｃ，１６ｄが矩形状の容器であって、バケット１６の上部にはスクリューフィーダー１２を通過した食品４を受け入れる受入口が設けられている。また、バケット１６の側部（図１の紙面左に位置する側部）１６ｃの内壁面は、図１及び図２に示すように、バケット１６の受入口から供給された食品４が滑り落ちるように傾斜面となっている。また、バケット１６の側部（図１の紙面右に位置する側部）１６ｄは、バケット１６の蓋として機能し、上辺または上辺近傍を軸として回動可能に構成されている。即ち、バケット１６の側部１６ｄが図１の位置Ａのとき、バケット１６の側部１６ｃと１６ｄによりバケット１６の排出口は閉じられているため、食品４は、バケット１６内に貯留する。一方、バケット１６の側部１６ｄが図１の位置Ｂのとき、バケット１６の側部１６ｃと１６ｄによりバケット１６の排出口は開いているため、バケット１６内の食品４は、側部１６ｃを滑り落ち、バケット１６の排出口から排出され、図１の矢印Ａ５に示すように、下流側のシュート２０に搬送される。 The bucket 16 is a container that receives the food 4 to be weighed by the measuring unit 18. FIG. 2 is a perspective view showing the configuration of the bucket 16. As shown in FIG. 2, the bucket 16 has two opposite side portions (two side portions located before and after the paper surface of FIG. 1) 16a and 16b having an inverted triangular shape and the other two side portions facing each other (FIG. 1). The two sides) 16c and 16d located on the left and right sides of the paper are rectangular containers, and the upper part of the bucket 16 is provided with a receiving port for receiving the food 4 that has passed through the screw feeder 12. Further, as shown in FIGS. 1 and 2, the inner wall surface of the side portion (side portion located on the left side of the paper surface in FIG. 1) 16c of the bucket 16 slides down the food 4 supplied from the receiving port of the bucket 16. It is an inclined surface. Further, the side portion 16d of the bucket 16 (the side portion located on the right side of the paper surface in FIG. 1) functions as a lid of the bucket 16 and is configured to be rotatable around the upper side or the vicinity of the upper side. That is, when the side portion 16d of the bucket 16 is at the position A in FIG. 1, the outlet of the bucket 16 is closed by the side portions 16c and 16d of the bucket 16, so that the food 4 is stored in the bucket 16. On the other hand, when the side portion 16d of the bucket 16 is at the position B in FIG. 1, the outlet of the bucket 16 is opened by the side portions 16c and 16d of the bucket 16, so that the food 4 in the bucket 16 slides on the side portion 16c. It falls, is discharged from the discharge port of the bucket 16, and is conveyed to the chute 20 on the downstream side as shown by arrow A5 in FIG.
バケット１６の側部１６ｃの食品４が接触する内壁面（傾斜面）には、食品４が付着しやすい箇所であることから、図２に示すように、食品４の進行方向に沿って複数の溝部２４と、隣り合う溝部２４の間に食品４の進行方向に沿って稜線状の頂部２６とが規則的に形成されている。また、バケット１６の側部１６ａの内壁面（図示せず）、バケット１６の側部１６ｂの内壁面も側部１６ｃと同様に溝部が形成されている。 Since the food 4 is likely to adhere to the inner wall surface (inclined surface) of the side portion 16c of the bucket 16 in contact with the food 4, as shown in FIG. 2, a plurality of foods 4 are oriented along the traveling direction of the food 4. A ridge-shaped top 26 is regularly formed between the groove 24 and the adjacent groove 24 along the traveling direction of the food 4. Further, the inner wall surface of the side portion 16a of the bucket 16 (not shown) and the inner wall surface of the side portion 16b of the bucket 16 are also formed with grooves in the same manner as the side portion 16c.
図３は、溝部２４及び頂部２６の形状について説明するための図であって、側部１６ｃの内壁面（傾斜面）の構成を示す断面図である。図３に示すように、溝部２４の断面形状は円弧状（半円状）であって、溝部２４の配置間隔Ｐは溝部２４の幅Ｄ１の１．００倍以上１．１０倍以下であり、好ましくは１．０２倍以上１．０６倍以下である。溝部２４の配置間隔Ｐが小さいと頂部２６の幅Ｄ２が小さくなり、例えば図５に示す従来の傾斜面の断面形状である波型形状と比較して、食品４と側部１６ｃの内壁面との接触面積を小さくすることができる。 FIG. 3 is a view for explaining the shapes of the groove portion 24 and the top portion 26, and is a cross-sectional view showing the configuration of the inner wall surface (inclined surface) of the side portion 16c. As shown in FIG. 3, the cross-sectional shape of the groove portion 24 is an arc shape (semicircular shape), and the arrangement interval P of the groove portion 24 is 1.00 times or more and 1.10 times or less of the width D1 of the groove portion 24. It is preferably 1.02 times or more and 1.06 times or less. When the arrangement interval P of the groove portions 24 is small, the width D2 of the top portion 26 becomes small, and the food 4 and the inner wall surface of the side portion 16c are compared with the corrugated shape which is the cross-sectional shape of the conventional inclined surface shown in FIG. The contact area of the can be reduced.
また、溝部２４の幅Ｄ１は、食品４の最大長さの１／１０倍以上２／３倍以下であり、好ましくは１／５倍以上１／２倍以下である。食品４が直方体形状である場合、溝部２４の幅Ｄ１は、食品４の最も長い辺の長さまたは二番目に長い辺の長さの１／１０倍以上２／３倍以下であり、好ましくは１／５倍以上１／２倍以下である。例えば直方体形状にカットされた具材等、縦の長さ及び横に長さに比して厚さが薄い食品４の場合、溝部２４の幅Ｄ１は、縦の長さまたは横の長さの１／１０倍以上２／３倍以下、好ましくは１／５倍以上１／２倍以下とする。 Further, the width D1 of the groove portion 24 is 1/10 times or more and 2/3 times or less, preferably 1/5 times or more and 1/2 times or less the maximum length of the food 4. When the food 4 has a rectangular parallelepiped shape, the width D1 of the groove 24 is 1/10 or more and 2/3 times or less the length of the longest side or the second longest side of the food 4, preferably. It is 1/5 times or more and 1/2 times or less. For example, in the case of food 4 having a vertical length and a thickness smaller than the horizontal length, such as an ingredient cut into a rectangular parallelepiped shape, the width D1 of the groove 24 is the vertical length or the horizontal length. It is 1/10 times or more and 2/3 times or less, preferably 1/5 times or more and 1/2 times or less.
また、食品４が円柱形状である場合、溝部２４の幅Ｄ１は、食品４の直径の長さの１／１０倍以上２／３倍以下であり、好ましくは１／５倍以上１／２倍以下である。例えば円柱形状にカットされた具材等、円の直径の長さに比して厚さが薄い食品４の場合、溝部２４の幅Ｄ１は、直径の長さの１／１０倍以上２／３倍以下、好ましくは１／５倍以上１／２倍以下とする。また、食品４が楕円柱形状である場合、溝部２４の幅Ｄ１は、食品４の短径の長さの１／１０倍以上２／３倍以下であり、好ましくは１／５倍以上１／２倍以下である。例えば楕円柱形状にカットされた具材等、楕円の短径の長さに比して厚さが薄い食品４の場合、溝部２４の幅Ｄ１は、短径の長さの１／１０倍以上２／３倍以下、好ましくは１／５倍以上１／２倍以下とする。円柱形状または楕円形状の食品４の厚さが円または楕円の大きさに対して厚い場合には、溝部２４の幅Ｄ１は、厚さの１／１０倍以上２／３倍以下、好ましくは１／５倍以上１／２倍以下とする。 When the food 4 has a cylindrical shape, the width D1 of the groove 24 is 1/10 times or more and 2/3 times or less, preferably 1/5 times or more and 1/2 times the length of the diameter of the food 4. It is as follows. For example, in the case of food 4 whose thickness is thinner than the length of the diameter of a circle, such as an ingredient cut into a cylindrical shape, the width D1 of the groove 24 is 1/10 or more and 2/3 of the length of the diameter. It is doubled or less, preferably 1/5 times or more and 1/2 times or less. When the food 4 has an elliptical pillar shape, the width D1 of the groove 24 is 1/10 times or more and 2/3 times or less, preferably 1/5 times or more and 1 / of the length of the minor axis of the food 4. It is less than twice. For example, in the case of food 4 whose thickness is thinner than the length of the minor axis of the ellipse, such as an ingredient cut into an elliptical column shape, the width D1 of the groove 24 is 1/10 times or more the length of the minor axis. It is 2/3 times or less, preferably 1/5 times or more and 1/2 times or less. When the thickness of the cylindrical or elliptical food 4 is thicker than the size of the circle or ellipse, the width D1 of the groove 24 is 1/10 or more and 2/3 times or less, preferably 1 of the thickness. / 5 times or more and 1/2 times or less.
また、食品４の形状として上述以外にも細長いものまたは球形状のものなど、様々な形状が挙げられるが、各形状の最大長さ、最小長さ及び最大長さと最小長さとの比等に応じて、溝部２４の幅Ｄ１は決定される。 In addition to the above, various shapes such as an elongated shape or a spherical shape can be mentioned as the shape of the food 4, and the maximum length, the minimum length, and the ratio of the maximum length to the minimum length of each shape can be used. Therefore, the width D1 of the groove portion 24 is determined.
計量部１８は、バケット１６内の食品４を計量する。具体的には、バケット１６の側部１６ｃと１６ｄによりバケット１６の排出口を閉じた状態（側部１６ｄが図１の位置Ａ）において、バケット１６内に貯留された食品４の重量を計る。 The measuring unit 18 weighs the food 4 in the bucket 16. Specifically, the weight of the food 4 stored in the bucket 16 is weighed in a state where the discharge port of the bucket 16 is closed by the side portions 16c and 16d of the bucket 16 (the side portion 16d is the position A in FIG. 1).
シュート２０は、バケット１６から排出された食品４を、食品４を収容する容器２２（図１参照）まで誘導する。シュート２０は上部の四側部が逆台形状及び下部の四側部が矩形状の角筒であって、シュート２０の上部にはバケット１６から排出された食品４を受け入れる受入口が設けられている。また、シュート２０の下部にはシュート２０内を通過した食品４を容器２２に排出する排出口が設けられている。 The chute 20 guides the food 4 discharged from the bucket 16 to the container 22 (see FIG. 1) containing the food 4. The chute 20 has an inverted trapezoidal shape on the upper four sides and a rectangular tube on the lower four sides, and a receiving port for receiving the food 4 discharged from the bucket 16 is provided on the upper part of the chute 20. There is. Further, a discharge port for discharging the food 4 that has passed through the chute 20 to the container 22 is provided below the chute 20.
この実施の形態に係る計量装置２において、計量部１８は、上ホッパー６、下ホッパー１０及び切り出し装置、例えばスクリューフィーダー１２を通過しバケット１６内に貯留した食品４の重量を計り、図示しない制御部に計量結果を出力する。制御部は、計量結果が予め設定された所定重量に近づくと、スクリューフィーダー１２の回転速度を減じ、バケット１６内に投入される食品４の量を制限する。そして、制御部は、所定重量に達すると、バケット１６の側部１６ｄを図１の紙面右側に回動させることによりバケット１６の排出口を開く（側部１６ｄが図１の位置Ｂ）。バケット１６内の食品４は、バケット１６の排出口から排出され、下流側のシュート２０を介して容器２２に収容される。制御部は、バケット１６内の食品４がすべて排出されると、バケット１６の側部１６ｄを図１の紙面左側に回動させることによりバケット１６の排出口を閉じ（側部１６ｄが図１の位置Ａ）、スクリューフィーダー１２の回転速度を上げることにより、食品４のバケット１６への投入を再開させ、上述の動作を繰り返す。 In the weighing device 2 according to this embodiment, the weighing unit 18 weighs the food 4 stored in the bucket 16 through the upper hopper 6, the lower hopper 10 and the cutting device, for example, the screw feeder 12, and controls (not shown). The weighing result is output to the unit. When the weighing result approaches a preset predetermined weight, the control unit reduces the rotation speed of the screw feeder 12 and limits the amount of food 4 to be put into the bucket 16. Then, when the control unit reaches a predetermined weight, the side portion 16d of the bucket 16 is rotated to the right side of the paper surface of FIG. 1 to open the discharge port of the bucket 16 (the side portion 16d is the position B in FIG. 1). The food 4 in the bucket 16 is discharged from the discharge port of the bucket 16 and is stored in the container 22 via the chute 20 on the downstream side. When all the food 4 in the bucket 16 is discharged, the control unit closes the discharge port of the bucket 16 by rotating the side portion 16d of the bucket 16 to the left side of the paper surface of FIG. 1 (the side portion 16d is shown in FIG. 1). At position A), by increasing the rotation speed of the screw feeder 12, the food 4 is restarted into the bucket 16 and the above operation is repeated.
この実施の形態に係る計量装置２によれば、バケット１６の側部１６ａ〜１６ｃの内壁面が複数の溝部２４及び複数の頂部２６により形成されているため、被計量物である食品４と内壁面との接触面積を小さくすることができる。したがって、食品４の内壁面への付着を防止することができ、計量精度を向上させることができる。また、内壁面に付着した食品４を振り落とすためにバケット１６を振動させる構造等を有する計量装置よりも食品４の自動計量を迅速に連続して行うことができる。また、内壁面にフッ素コーティング等を施した計量装置よりも、コーティング剥離等の劣化が少ないため、食品４の自動計量を精度よく連続して行うことができる。 According to the weighing device 2 according to this embodiment, since the inner wall surface of the side portions 16a to 16c of the bucket 16 is formed by the plurality of groove portions 24 and the plurality of top portions 26, the food 4 and the inner surface to be measured are formed. The contact area with the wall surface can be reduced. Therefore, it is possible to prevent the food 4 from adhering to the inner wall surface, and it is possible to improve the measurement accuracy. Further, the automatic weighing of the food 4 can be performed more quickly and continuously than the measuring device having a structure for vibrating the bucket 16 in order to shake off the food 4 adhering to the inner wall surface. Further, since the deterioration such as coating peeling is less than that of the weighing device having the inner wall surface coated with fluorine or the like, the automatic weighing of the food 4 can be performed continuously with high accuracy.
なお、この実施の形態に係る計量装置２においては、バケット１６の側部１６ａ〜１６ｃの内壁面に溝部２４及び頂部２６が形成されているが、バケット１６の側部１６ａ〜１６ｄの少なくとも１つの内壁面に溝部２４及び頂部２６が形成されていればよい。また、バケット１６の側部１６ａ〜１６ｃの内壁面全体に溝部２４及び頂部２６が形成されている場合を例に挙げて説明したが、バケット１６の側部１６ａ〜１６ｄの少なくとも一部の内壁面に溝部２４及び頂部２６を形成する構成にしてもよい。 In the weighing device 2 according to this embodiment, the groove portion 24 and the top portion 26 are formed on the inner wall surface of the side portions 16a to 16c of the bucket 16, but at least one of the side portions 16a to 16d of the bucket 16 is formed. It suffices if the groove 24 and the top 26 are formed on the inner wall surface. Further, the case where the groove portion 24 and the top portion 26 are formed on the entire inner wall surface of the side portions 16a to 16c of the bucket 16 has been described as an example, but at least a part of the inner wall surface of the side portions 16a to 16d of the bucket 16 has been described. The groove portion 24 and the top portion 26 may be formed in the groove portion 24.
また、この実施の形態に係る計量装置２においては、バケット１６の内壁面のみに溝部２４及び頂部２６が形成されている場合を例に挙げて説明したが、シュート２０の内壁面の少なくとも一部にも溝部２４及び頂部２６を形成してもよい。同様に、上ホッパー６及び下ホッパー８の内壁面の少なくとも一部にも溝部２４及び頂部２６を形成してもよい。 Further, in the weighing device 2 according to this embodiment, the case where the groove portion 24 and the top portion 26 are formed only on the inner wall surface of the bucket 16 has been described as an example, but at least a part of the inner wall surface of the chute 20 has been described. The groove 24 and the top 26 may also be formed. Similarly, the groove portion 24 and the top portion 26 may be formed on at least a part of the inner wall surface of the upper hopper 6 and the lower hopper 8.
また、この実施の形態に係る計量装置２においては、バケット１６の内壁面の少なくとも一部に断面形状が半円形状の溝部２４が規則的に複数形成されている場合を例に挙げて説明したが、断面形状が例えば図４（ａ）に示すような半円形状以外の円弧状、楕円弧状の溝部であってもよい。また、溝部の底隅部が円弧状の湾曲面とされた断面形状であってもよい。例えば図４（ｂ）に示すような溝部の底の隅部（角部）が湾曲面とされた（面取りされた）逆台形状、図４（ｃ）に示すような隅部（角部）が湾曲面とされた（面取りされた）Ｖ字形状等、溝部の隅部（角部）が湾曲面とされた（面取りされた）形状の溝部であってもよい。溝部の底隅部（底角部）を湾曲面と（面取り）することにより食品４の溝部への詰まりを防止する。 Further, in the weighing device 2 according to this embodiment, a case where a plurality of groove portions 24 having a semicircular cross section are regularly formed on at least a part of the inner wall surface of the bucket 16 will be described as an example. However, the cross-sectional shape may be an arc-shaped or elliptical arc-shaped groove other than the semicircular shape as shown in FIG. 4A, for example. Further, the cross-sectional shape may be such that the bottom corner portion of the groove portion is an arcuate curved surface. For example, an inverted trapezoidal shape in which the bottom corner (corner) of the groove as shown in FIG. 4 (b) is a curved surface (chamfered), and the corner (corner) as shown in FIG. 4 (c). May be a groove having a curved surface (chamfered), such as a V-shape having a curved surface (chamfered) at the corners (corners) of the groove. By forming the bottom corner portion (bottom corner portion) of the groove portion with the curved surface (chamfering), clogging of the food 4 in the groove portion is prevented.
また、この実施の形態に係る計量装置２では被計量物として食品４を例に挙げて説明したが、食品以外の自動計量に適した他の被計量物を計量する計量装置においても本発明を適用することができる。 Further, in the weighing device 2 according to this embodiment, the food 4 is taken as an example as an example to be measured, but the present invention is also used in a weighing device that measures other objects to be measured other than foods that are suitable for automatic weighing. Can be applied.
