　本発明は、組合せ計量装置、より具体的には、物品を周方向に分散させる２つの分散テーブルと、２つの分散テーブルの間に配置され、物品を分散テーブルに供給する供給手段と、を備えた組合せ計量装置に関する。 The present invention includes a combination weighing device, more specifically, two dispersion tables that disperse an article in a circumferential direction, and a supply unit that is disposed between the two dispersion tables and supplies the article to the dispersion table. The present invention relates to a combination weighing device.
　従来、物品を周方向に分散させる２つの分散テーブルと、２つの分散テーブルの間に配置され、物品を分散テーブルに供給する供給手段と、を備えた組合せ計量装置が知られている。例えば、特許文献１（特開２０１４－１０５９９４号公報）には、それぞれが分散テーブルの一方に対応し、対応する分散テーブルに向かって下方傾斜する、２つのトラフを有し、トラフを回転振動させることで、トラフの傾斜と回転振動とにより物品を搬送し、分散テーブルに物品を供給する供給手段を備えた組合せ計量装置が開示されている。 2. Description of the Related Art Conventionally, a combination weighing device is known that includes two dispersion tables that disperse articles in the circumferential direction and a supply unit that is disposed between the two dispersion tables and supplies articles to the dispersion table. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2014-105994) has two troughs each corresponding to one of the dispersion tables and inclined downward toward the corresponding dispersion table, and rotationally vibrates the troughs. Thus, a combination weighing device including a supply unit that conveys an article by the inclination of the trough and rotational vibration and supplies the article to a dispersion table is disclosed.
　２つの分散テーブルを備えた組合せ計量装置では、装置をコンパクトに構成するため、分散テーブルはできるだけ近づけて配置されることが好ましい。それゆえ、供給手段も、コンパクトに構成されることが好ましく、特許文献１（特開２０１４－１０５９９４号公報）のように供給手段が物品を搬送するトラフを有する場合、トラフの搬送方向の長さは出来るだけ短く構成される。 In a combination weighing device having two dispersion tables, it is preferable that the dispersion tables are arranged as close as possible in order to make the device compact. Therefore, the supply means is also preferably configured in a compact manner. When the supply means has a trough for conveying an article as in Patent Document 1 (Japanese Patent Laid-Open No. 2014-105994), the length of the trough in the conveyance direction is preferable. Is constructed as short as possible.
　しかし、このような長さの短いトラフが用いられる場合には、長さの長いトラフが用いられる場合に比べ、特に搬送性が悪い物品を搬送する際に、分散テーブルへの物品の供給量が不十分になりやすい。 However, when such a short trough is used, the amount of articles supplied to the dispersal table is reduced particularly when an article having poor transportability is transported, compared to the case where a long trough is used. It tends to be insufficient.
　本発明の課題は、それぞれが物品を分散する２つの分散テーブルの一方に物品を搬送する２つのトラフ、を有する組合せ計量装置であって、トラフによる物品の搬送量不足が発生しにくい組合せ計量装置を提供することにある。 An object of the present invention is a combination weighing apparatus having two troughs for conveying articles to one of two dispersion tables each dispersing articles, and a combination weighing apparatus that is unlikely to cause shortage in the conveyance amount of articles by the troughs Is to provide.
　本発明の第１観点に係る組合せ計量装置は、２つの分散テーブルと、供給手段と、を備える。分散テーブルは、回動して、上部に供給される物品を周方向に分散させる。供給手段は、上面視において２つの分散テーブルの間に配置され、２つの分散テーブルに物品を供給する。供給手段は、物品を搬送する２つのトラフと、２つの加振部と、を有する。２つの加振部は、それぞれがトラフの一方に対応し、対応するトラフをリニア振動させる。分散テーブルの一方へと物品を搬送するトラフの一方と、分散テーブルの他方へと物品を搬送するトラフの他方とは、互いの背面同士が隣接するように配置される。 The combination weighing device according to the first aspect of the present invention includes two distribution tables and supply means. The dispersion table rotates to disperse the article supplied to the upper part in the circumferential direction. The supply means is disposed between the two dispersion tables in a top view and supplies articles to the two dispersion tables. The supply means includes two troughs that convey the article and two vibration units. Each of the two vibration units corresponds to one of the troughs and linearly vibrates the corresponding trough. One trough that transports articles to one of the dispersion tables and the other trough that transports articles to the other of the dispersion tables are arranged such that their backs are adjacent to each other.
　本発明の第１観点に係る組合せ計量装置では、トラフが、回転振動ではなく、リニア振動させられるため、トラフにより物品を安定して搬送することが容易で、トラフによる物品の搬送量不足を抑制することが可能である。 In the combination weighing device according to the first aspect of the present invention, since the trough is caused to linearly vibrate instead of rotational vibration, it is easy to stably convey the article by the trough, and suppress the shortage of the article conveyance amount by the trough. Is possible.
　本発明の第２観点に係る組合せ計量装置は、第１観点に係る組合せ計量装置であって、加振部のそれぞれは、対応するトラフの搬送方向と直交する、対応するトラフの幅方向に、互いに間隔を空けて並べられた、複数のコイルを有する。 The combination weighing device according to the second aspect of the present invention is the combination weighing device according to the first aspect, wherein each of the vibration units is in the width direction of the corresponding trough perpendicular to the conveyance direction of the corresponding trough. It has a plurality of coils that are spaced apart from one another.
　長さの短いトラフを用いつつ、分散テーブルへの物品供給量を十分に確保するためには、トラフに振動を発生させる電磁フィーダのコイルを大型化し、トラフの振幅を大きくするという対応が考えられる。しかし、コイルを大型化した場合には、コイルの放熱性が悪化するという別の問題が生じる。 In order to ensure a sufficient supply of goods to the dispersal table while using a trough having a short length, it is possible to increase the size of the trough amplitude by increasing the size of the coil of the electromagnetic feeder that generates vibration in the trough. . However, when the coil is enlarged, another problem that the heat dissipation of the coil is deteriorated occurs.
　これに対し、本発明の第２観点に係る組合せ計量装置では、各加振部が、対応するトラフの幅方向に複数のコイルを有することで、トラフによる物品の搬送量を大きく確保することを可能としている。また、本発明の第２観点に係る組合せ計量装置では、複数のコイルを有することで、１つの大きなコイルを用いる場合に比べて表面積を大きく確保することができ、さらに複数のコイルは空気が通る隙間を確保するように互いに間隔を空けて並べられていることから、１つの大きなコイルを有する場合に比べてコイルの放熱性を良好に保つことができる。 On the other hand, in the combination weighing device according to the second aspect of the present invention, each excitation unit has a plurality of coils in the width direction of the corresponding trough, thereby ensuring a large amount of articles conveyed by the trough. It is possible. Further, in the combination weighing device according to the second aspect of the present invention, by having a plurality of coils, a larger surface area can be secured as compared with the case where one large coil is used, and further, the plurality of coils pass air. Since the gaps are arranged so as to ensure a gap, the heat dissipation of the coils can be maintained better than when one large coil is provided.
　本発明の第３観点に係る組合せ計量装置は、第２観点に係る組合せ計量装置であって、各加振部のコイルのそれぞれは、該加振部に対応するトラフ側に向けられ、該加振部に対応するトラフの搬送方向に並ぶ、Ｎ極およびＳ極を有する。 A combination weighing device according to a third aspect of the present invention is the combination weighing device according to the second aspect, wherein each of the coils of each excitation unit is directed to the trough side corresponding to the excitation unit, and It has N poles and S poles arranged in the trough transport direction corresponding to the vibration part.
　本発明の第３観点に係る組合せ計量装置では、加振部の各コイルが、トラフの搬送方向に並ぶＮ極およびＳ極を有する。言い換えれば、本発明の第３観点に係る組合せ計量装置では、対応するトラフの搬送方向にも複数のコイルが並べられている。そのため、トラフによる物品の搬送量を大きく確保することが可能である。また、複数のコイルを有することで、１つの大きなコイルを用いる場合に比べて表面積を大きく確保することができ、さらに複数のコイルが間隔を空けて並べられることから、コイルの放熱性を良好に保つことができる。 In the combination weighing device according to the third aspect of the present invention, each coil of the vibration unit has an N pole and an S pole arranged in the trough transport direction. In other words, in the combination weighing device according to the third aspect of the present invention, a plurality of coils are also arranged in the corresponding trough conveyance direction. Therefore, it is possible to ensure a large amount of articles conveyed by the trough. In addition, by having a plurality of coils, a larger surface area can be ensured compared to the case of using one large coil, and furthermore, since the plurality of coils are arranged at intervals, the heat dissipation of the coil is improved. Can keep.

The articles conveyed by the radiation trough 40 are supplied to a pool hopper 50 disposed below the downstream end of the radiation trough 40. The pool hopper 50 temporarily stores the articles supplied from the radiation trough 40 and then supplies the articles to the weighing hopper 60 disposed below the pool hopper 50. In the weighing hopper 60, the weight of the article supplied from the pool hopper 50 is measured. The articles in the weighing hopper 60 are put into a booster hopper 70 disposed below the weighing hopper 60 after weighing. The control unit 90 performs a combination calculation based on the weight of the article in the weighing hopper 60 and the weight of the article temporarily stored in the booster hopper 70. The control unit 90 selects a combination of hoppers whose combination calculation results are within a predetermined allowable range and closest to the target value, and discharges articles from the hoppers included in the selected combination. The articles discharged from the booster hopper 70 are collected in the collective discharge chute 80 and discharged from the discharge port 81 of the collective discharge chute 80 (see FIG. 2).

FIG. 5 is a view of the supply trough 11 as viewed from the downstream side in the conveyance direction D1 (see arrow A in FIG. 4) along the conveyance direction D1 (see arrow in FIG. 4) of the article of the supply trough 11. . In other words, FIG. 5 is a view of the supply trough 11 as viewed from the distribution table 30 side where the supply trough 11 supplies articles.
　供給トラフ１１は、図４のように、その供給トラフ１１の物品の搬送方向Ｄ１に沿って延びる２つの側壁１１ａを有する。また、供給トラフ１１は、図４のように、その供給トラフ１１の搬送方向Ｄ１の上流側に背面壁１１ｂを有する。供給トラフ１１は、図５のように、その供給トラフ１１の搬送方向Ｄ１の下流側から見た時に、Ｕ字形状に形成されている。より具体的には、供給トラフ１１は、その供給トラフ１１の搬送方向Ｄ１の下流側から見た時に、各側壁１１ａの下端から、２つの側壁１１ａ間の中央部に向かって次第に低くなるように傾斜した底面１１ｃを有する。供給トラフ１１は、この底面１１ｃと、２つの側壁１１ａとにより、搬送方向Ｄ１の下流側から見た時にＵ字形状に形成されている（図５参照）。供給トラフ１１は、組合せ計量装置１００に、水平に取り付けられている。つまり、供給トラフ１１は、供給トラフ加振部２０により振動させられていない状態で、底面１１ｃが供給トラフ１１の搬送方向Ｄ１に沿って傾斜しないように組合せ計量装置１００に取り付けられている。 The supply trough 11 has two side walls 11a extending along the conveyance direction D1 of the articles of the supply trough 11, as shown in FIG. Moreover, the supply trough 11 has the back wall 11b in the upstream of the conveyance direction D1 of the supply trough 11, as shown in FIG.

The supply trough 11 is attached to the combination weighing device 100 horizontally. That is, the supply trough 11 is attached to the combination weighing device 100 so that the bottom surface 11 c does not tilt along the conveyance direction D <b> 1 of the supply trough 11 in a state where the supply trough 11 is not vibrated by the supply trough vibration unit 20.
　ここでは、供給トラフ１１の搬送方向Ｄ１の長さＬ（背面壁１１ｂから供給トラフ１１の搬送方向Ｄ１の最下流の先端部１１ｄまでの距離、図４参照）を短くしつつ、供給トラフ１１の搬送量を確保するため、供給トラフ１１の幅Ｗ（側壁１１ａ間の距離、図４参照）が幅広に設計されている。具体的には、供給トラフ１１の幅Ｗは、供給トラフ１１の搬送方向Ｄ１の長さＬと略等しく設計されている。より具体的には、供給トラフ１１の幅Ｗは、供給トラフ１１の搬送方向Ｄ１の長さＬに対し、Ｗ≧０．７Ｌとなるように設計されている。つまり、供給トラフ１１は、供給トラフ１１の幅Ｗの、供給トラフ１１の搬送方向Ｄ１の長さＬに対する比（Ｗ／Ｌ）が、０．７以上となるように設計されている。さらに好ましくは、供給トラフ１１は、供給トラフ１１の幅Ｗの、供給トラフ１１の搬送方向Ｄ１の長さＬに対する比（Ｗ／Ｌ）が、０．８以上となるように設計される。例えば、本実施形態に係る組合せ計量装置１００では、Ｗ＝０．８５Ｌである。 Here, the length of the supply trough 11 in the conveying direction D1 (the distance from the rear wall 11b to the most downstream end portion 11d in the conveying direction D1 of the supply trough 11, see FIG. 4) is shortened. In order to secure the conveyance amount, the width W of the supply trough 11 (distance between the side walls 11a, see FIG. 4) is designed to be wide. Specifically, the width W of the supply trough 11 is designed to be substantially equal to the length L of the supply trough 11 in the transport direction D1. More specifically, the width W of the supply trough 11 is designed so that W ≧ 0.7L with respect to the length L of the supply trough 11 in the transport direction D1. That is, the supply trough 11 is designed so that the ratio (W / L) of the width W of the supply trough 11 to the length L of the supply trough 11 in the transport direction D1 is 0.7 or more. More preferably, the supply trough 11 is designed such that the ratio (W / L) of the width W of the supply trough 11 to the length L in the transport direction D1 of the supply trough 11 is 0.8 or more. For example, in the combination weighing device 100 according to the present embodiment, W = 0.85L.
　また、ここでは、供給トラフ１１の搬送方向Ｄ１の長さＬを短くしつつ、供給トラフ１１の搬送量を確保するため、供給トラフ１１は、下方に大きく凹んだ形状に設計されている。具体的には、供給トラフ１１の高さＴ（底面１１ｃの最も低い位置から側壁１１ａの上端までの距離、図５参照））は、供給トラフ１１の搬送方向Ｄ１の長さＬの１／４以上（Ｔ≧０．２５Ｌ）に設計されている。つまり、供給トラフ１１は、供給トラフ１１の高さＴの、供給トラフ１１の搬送方向Ｄ１の長さＬに対する比（Ｔ／Ｌ）が、０．２５以上となるように設計されている。さらに好ましくは、供給トラフ１１は、供給トラフ１１の高さＴの、供給トラフ１１の搬送方向Ｄ１の長さＬに対する比（Ｔ／Ｌ）が、０．３以上となるように設計される。例えば、本実施形態に係る組合せ計量装置１００では、Ｗ＝１／３Ｌ（≒０．３３Ｌ）である。 Further, here, the supply trough 11 is designed to have a shape that is greatly recessed downward in order to secure the conveyance amount of the supply trough 11 while shortening the length L of the supply trough 11 in the conveyance direction D1. Specifically, the height T of the supply trough 11 (the distance from the lowest position of the bottom surface 11c to the upper end of the side wall 11a, see FIG. 5) is ¼ of the length L of the supply trough 11 in the transport direction D1. The above is designed (T ≧ 0.25L). That is, the supply trough 11 is designed such that the ratio (T / L) of the height T of the supply trough 11 to the length L in the transport direction D1 of the supply trough 11 is 0.25 or more. More preferably, the supply trough 11 is designed such that the ratio (T / L) of the height T of the supply trough 11 to the length L in the transport direction D1 of the supply trough 11 is 0.3 or more. For example, in the combination weighing device 100 according to the present embodiment, W = 1 / 3L (≈0.33L).

In other words, in the top view, the most downstream end portion 11d in the transport direction D1 of each supply trough 11 is disposed above the center 30a of the distribution table 30 to which the articles of the supply trough 11 are transported (see FIG. 1). ).

That is, the base 22 is installed on the plurality of coil springs 21. Each leaf spring 23 has a lower end attached to the base 22 and an upper end connected to the connecting member 24. From the upper surface of the connecting member 24, the vibration portion side connection portion 25 extends upward. The vibration part side connection part 25 is a member for connecting the supply trough 11 and the supply trough vibration part 20.
　供給トラフ１１と供給トラフ加振部２０との接続状態について、図８を用いて詳しく説明する。図８は、物品供給部１０を、供給トラフ１１の搬送方向Ｄ１に沿って、物品の搬送方向Ｄ１の下流側、すなわち、その供給トラフ１１の物品の搬送先の分散テーブル３０側から見た概略図である。 The connection state between the supply trough 11 and the supply trough vibration unit 20 will be described in detail with reference to FIG.

The 1st permanent magnet 26a and the 2nd permanent magnet 26b of the magnet part 26 of the supply trough vibration part 20 are arranged along the conveyance direction D1 of the supply trough 11 matched with the supply trough vibration part 20 ( (See FIG. 10). More specifically, the first permanent magnet 26a and the second permanent magnet 26b are configured such that the second permanent magnet 26b conveys the article of the supply trough 11 more than the first permanent magnet 26a along the conveyance direction D1 of the supply trough 11. It arranges so that it may be arrange | positioned in the downstream of the direction D1 (refer FIG. 10).
　第１永久磁石２６ａは、Ｎ極が下方（コイル２７側）を向くように配置されている。一方、第２永久磁石２６ｂは、Ｓ極が下方（コイル２７側）を向くように配置されている。なお、磁極の向きは例示であって、例えば、第１永久磁石２６ａはＳ極が下方を向くように配置され、第２永久磁石２６ｂは、Ｎ極が下方を向くように配置されてもよい。 The first permanent magnet 26a is arranged so that the N pole faces downward (coil 27 side).

The direction of the magnetic pole is an example, and for example, the first permanent magnet 26a may be arranged so that the south pole faces downward, and the second permanent magnet 26b may be arranged so that the north pole faces downward. .
　ベース２２上には、各磁石部２６の下方にコイル２７が配置されている。つまり、供給トラフ加振部２０のベース２２上には、その供給トラフ加振部２０と対応する供給トラフ１１の搬送方向Ｄ１と直交する方向（つまり対応する供給トラフ１１の幅方向）に並べて、２つのコイル２７が取り付けられる（図８参照）。なお、２つのコイル２７のそれぞれは、供給トラフ１１の幅方向に、互いに間隔を空けてベース２２上に並べられている。つまり、２つのコイル２７は、その間に隙間Ｃが形成されるようにベース２２上に並べて配置されている（図８参照）。２つのコイル２７は、それぞれ、２つの磁石部２６の一方の下方に、磁石部２６と所定の距離を離して配置される（図８参照）。 On the base 22, a coil 27 is disposed below each magnet portion 26. That is, on the base 22 of the supply trough oscillating unit 20, the supply trough oscillating unit 20 is arranged in a direction orthogonal to the conveyance direction D1 of the supply trough 11 corresponding to the supply trough oscillating unit 20 (that is, the width direction of the corresponding supply trough 11). Two coils 27 are attached (see FIG. 8). Each of the two coils 27 is arranged on the base 22 at a distance from each other in the width direction of the supply trough 11. That is, the two coils 27 are arranged side by side on the base 22 so that a gap C is formed between them (see FIG. 8). Each of the two coils 27 is disposed below one of the two magnet portions 26 at a predetermined distance from the magnet portion 26 (see FIG. 8).
　各コイル２７は、第１電磁石２７ａおよび第２電磁石２７ｂの２つの電磁石を含む。第１電磁石２７ａおよび第２電磁石２７ｂは、それぞれ、上下方向に延びる磁性体の磁芯２８（図７参照）と、磁芯２８に巻き回される導線（図示せず）と、を含む。 Each coil 27 includes two electromagnets, a first electromagnet 27a and a second electromagnet 27b. Each of the first electromagnet 27a and the second electromagnet 27b includes a magnetic core 28 (see FIG. 7) extending in the vertical direction and a conductive wire (not shown) wound around the magnetic core 28.
　供給トラフ加振部２０の各コイル２７の第１電磁石２７ａおよび第２電磁石２７ｂは、その供給トラフ加振部２０と対応付けられる供給トラフ１１の搬送方向Ｄ１に並べられている。より具体的には第１電磁石２７ａおよび第２電磁石２７ｂは、供給トラフ１１の物品の搬送方向Ｄ１に沿って、第２電磁石２７ｂが第１電磁石２７ａよりも供給トラフ１１の搬送方向Ｄ１の下流側に配置されるように並べられている（図９および図１０参照）。第１電磁石２７ａおよび第２電磁石２７ｂは、供給トラフ１１の搬送方向Ｄ１に間隔を空けて並べられている。 The first electromagnet 27a and the second electromagnet 27b of each coil 27 of the supply trough vibration unit 20 are arranged in the conveyance direction D1 of the supply trough 11 associated with the supply trough vibration unit 20. More specifically, the first electromagnet 27a and the second electromagnet 27b are arranged such that the second electromagnet 27b is downstream of the first electromagnet 27a in the conveyance direction D1 of the supply trough 11 along the conveyance direction D1 of the article in the supply trough 11. (See FIGS. 9 and 10). The first electromagnet 27a and the second electromagnet 27b are arranged at intervals in the transport direction D1 of the supply trough 11.
　第１電磁石２７ａおよび第２電磁石２７ｂは、導線に交流電流が流れることで、磁極が互いに逆向きに励磁されるよう構成される。 1st electromagnet 27a and 2nd electromagnet 27b are comprised so that an alternating current may flow through a conducting wire and a magnetic pole may be excited in the opposite direction mutually.
　具体的に言えば、あるタイミング（第１タイミングと呼ぶ）で、第１電磁石２７ａの導線に電流が流されることで、第１電磁石２７ａは、上方側（磁石部２６側）にＳ極が配置されるように励磁される（図９および図１０参照）。言い換えれば、第１タイミングにおいて、供給トラフ加振部２０のコイル２７の第１電磁石２７ａは、その供給トラフ加振部２０の上方に配置される供給トラフ１１側にＳ極が配置されるように励磁される。この時（第１タイミングにおいて）、第２電磁石２７ｂの導線にも電流が流れ、第２電磁石２７ｂは、上方側（磁石部２６側）にＮ極が配置されるように励磁される（図９および図１０参照）。言い換えれば、第１タイミングにおいて、供給トラフ加振部２０のコイル２７の第２電磁石２７ｂは、その供給トラフ加振部２０の上方に配置される供給トラフ１１側にＮ極が配置されるように励磁される。 Specifically, at a certain timing (referred to as the first timing), a current is passed through the conducting wire of the first electromagnet 27a, so that the first electromagnet 27a has an S pole disposed on the upper side (magnet portion 26 side). (See FIGS. 9 and 10). In other words, at the first timing, the first electromagnet 27a of the coil 27 of the supply trough vibration unit 20 is arranged such that the S pole is disposed on the supply trough 11 side above the supply trough vibration unit 20. Excited. At this time (at the first timing), a current also flows through the conducting wire of the second electromagnet 27b, and the second electromagnet 27b is excited so that the N pole is disposed on the upper side (magnet portion 26 side) (FIG. 9). And FIG. 10). In other words, at the first timing, the second electromagnet 27b of the coil 27 of the supply trough vibration unit 20 is arranged such that the N pole is disposed on the supply trough 11 side above the supply trough vibration unit 20. Excited.
　別のタイミング（第２タイミングと呼ぶ）では、第１電磁石２７ａの導線に第１タイミングとは逆向きに電流が流されることで、第１電磁石２７ａは、上方側（磁石部２６側）にＮ極が配置されるように励磁される。言い換えれば、第２タイミングにおいて、供給トラフ加振部２０のコイル２７の第１電磁石２７ａは、その供給トラフ加振部２０の上方に配置される供給トラフ１１側にＮ極が配置されるように励磁される。この時（第２タイミングにおいて）、第２電磁石２７ｂの導線にも電流が流れ、第２電磁石２７ｂは、上方側（磁石部２６側）にＳ極が配置されるように励磁される。言い換えれば、第２タイミングにおいて、供給トラフ加振部２０のコイル２７の第２電磁石２７ｂは、その供給トラフ加振部２０の上方に配置される供給トラフ１１側にＳ極が配置されるように励磁される。 At another timing (referred to as second timing), a current flows in the direction opposite to the first timing through the conducting wire of the first electromagnet 27a, so that the first electromagnet 27a is N on the upper side (the magnet portion 26 side). Excited so that poles are placed. In other words, at the second timing, the first electromagnet 27a of the coil 27 of the supply trough vibration unit 20 is arranged such that the N pole is disposed on the supply trough 11 side above the supply trough vibration unit 20. Excited. At this time (at the second timing), a current also flows through the conducting wire of the second electromagnet 27b, and the second electromagnet 27b is excited so that the S pole is disposed on the upper side (magnet portion 26 side). In other words, at the second timing, the second electromagnet 27b of the coil 27 of the supply trough vibration unit 20 is arranged such that the S pole is disposed on the supply trough 11 side above the supply trough vibration unit 20. Excited.
　つまり、供給トラフ加振部２０のコイル２７のそれぞれは、供給トラフ加振部２０に対応する供給トラフ１１側に向けられ、供給トラフ加振部２０と対応する供給トラフ１１の搬送方向Ｄ１に並ぶ、Ｎ極およびＳ極を有する（図１０参照）。 That is, each of the coils 27 of the supply trough oscillating unit 20 is directed toward the supply trough 11 corresponding to the supply trough oscillating unit 20 and is arranged in the transport direction D1 of the supply trough 11 corresponding to the supply trough oscillating unit 20. , N pole and S pole (see FIG. 10).
　なお、２つのコイル２７は同様に構成されているため、供給トラフ加振部２０の２つのコイル２７のＮ極およびＳ極は、その供給トラフ加振部２０に対応する供給トラフ１１の幅方向（供給トラフ１１の搬送方向Ｄ１と直交する方向）に同一の磁極が並ぶよう配置される（図９参照）。 Since the two coils 27 are similarly configured, the N pole and the S pole of the two coils 27 of the supply trough vibration unit 20 are in the width direction of the supply trough 11 corresponding to the supply trough vibration unit 20. The same magnetic poles are arranged in a line (in a direction orthogonal to the conveyance direction D1 of the supply trough 11) (see FIG. 9).
　これら２つのコイル２７の第１電磁石２７ａおよび第２電磁石２７ｂに交流電流が加えられることで、第１永久磁石２６ａおよび第２永久磁石２６ｂには、下方への吸引力と、上方への反発力とが交互に作用する。その結果、磁石部２６が取り付けられた連結部材２４と、加振部側接続部２５、接続部材１３、およびトラフ側接続部１２を介して接続される供給トラフ１１が振動し、供給トラフ１１上を物品が搬送される。 By applying an alternating current to the first electromagnet 27a and the second electromagnet 27b of the two coils 27, the first permanent magnet 26a and the second permanent magnet 26b have a downward attracting force and an upward repulsive force. And act alternately. As a result, the connecting member 24 to which the magnet part 26 is attached, the supply trough 11 connected via the excitation part side connection part 25, the connection member 13, and the trough side connection part 12 vibrate, and the supply trough 11 The goods are conveyed.
　（２－３）分散テーブル
　各分散テーブル３０は、上面視において、概ね円形状に形成された部材である。分散テーブル３０には、物品供給部１０から物品が供給される。分散テーブル３０は、回動して、上部に供給される（分散テーブル３０上に供給される）物品を周方向に分散させる。分散テーブル３０は、物品供給部１０の供給トラフ１１より下方に配置されている（図２参照）。 (2-3) Dispersion Table Each dispersion table 30 is a member formed in a substantially circular shape when viewed from above. Articles are supplied from the article supply unit 10 to the dispersion table 30. The dispersion table 30 rotates to disperse articles supplied to the upper part (supplied on the dispersion table 30) in the circumferential direction. The dispersion table 30 is disposed below the supply trough 11 of the article supply unit 10 (see FIG. 2).
　各分散テーブル３０の下方には、分散部ロードセル３３（図３参照）が取り付けられている。分散部ロードセル３３は、分散テーブル３０上の物品の重量を計測する。 A dispersion section load cell 33 (see FIG. 3) is attached below each dispersion table 30. The dispersion part load cell 33 measures the weight of the article on the dispersion table 30.
　各分散テーブル３０は、主に、円錐部３０ｂと、水平部３０ｃとを有している（図２参照）。円錐部３０ｂは、中央部が高く（分散テーブル３０の中心３０ａが最も高く）、周縁部が低い円錐状の傾斜面を有する。水平部３０ｃは、円錐部３０ｂを取り囲むように形成された水平面を有する。 Each dispersion table 30 mainly has a conical portion 30b and a horizontal portion 30c (see FIG. 2). The conical portion 30b has a conical inclined surface with a high central portion (the center 30a of the dispersion table 30 is the highest) and a low peripheral portion. The horizontal part 30c has a horizontal plane formed so as to surround the conical part 30b.
　各分散テーブル３０の下方には、分散テーブル加振部３１が配置される（図２参照）。各分散テーブル３０は、その下面中央部において、分散テーブル加振部３１（図２参照）と連結されている。分散テーブル加振部３１は、分散テーブル３０に円周方向に沿った往復微振動を発生させる。言い換えれば、分散テーブル加振部３１は、分散テーブル３０を円周方向に回動させる。分散テーブル加振部３１の発生させる振動により、分散テーブル３０上の物品は一方向に旋回しながら径方向外側に移動する。 A distributed table excitation unit 31 is disposed below each distributed table 30 (see FIG. 2). Each distribution table 30 is connected to a distribution table excitation unit 31 (see FIG. 2) at the center of the lower surface. The dispersion table excitation unit 31 causes the dispersion table 30 to generate reciprocating micro vibrations along the circumferential direction. In other words, the distribution table exciting unit 31 rotates the distribution table 30 in the circumferential direction. Due to the vibration generated by the dispersion table exciting unit 31, the article on the dispersion table 30 moves radially outward while turning in one direction.
　水平部３０ｃの外周の一部の領域（分散テーブル３０の中心３０ａ周りの一部の角度領域）には、水平部３０ｃの外周に沿って延びる壁部材３２が取り付けられている（図２参照）。分散テーブル３０の中心３０ａ周りの水平部３０ｃに壁部材３２が取り付けられる角度領域は、分散テーブル３０の中心３０ａ周りのヘッドＨ（放射トラフ４０）が設けられていない角度領域と一致する。 A wall member 32 extending along the outer periphery of the horizontal portion 30c is attached to a portion of the outer periphery of the horizontal portion 30c (a part of the angular region around the center 30a of the dispersion table 30) (see FIG. 2). . The angle region where the wall member 32 is attached to the horizontal portion 30c around the center 30a of the dispersion table 30 coincides with the angle region where the head H (radiation trough 40) around the center 30a of the dispersion table 30 is not provided.
　壁部材３２により物品の排出が規制されるため、分散テーブル３０の中心３０ａ周りの壁部材３２が配置されている角度領域では、物品は分散テーブル３０の外周側から落下せず、分散テーブル３０上を壁部材３２のない角度領域まで運ばれていく。 Since the discharge of the article is regulated by the wall member 32, the article does not fall from the outer peripheral side of the dispersion table 30 in the angle region where the wall member 32 around the center 30 a of the dispersion table 30 is arranged, Is carried to an angle region where the wall member 32 is absent.
　具体的に、図１における右側の分散テーブル３０を例に説明する。図１における右側の分散テーブル３０では、物品は、分散テーブル３０上を反時計方向に循環しながら放射状に移動し、各ヘッドＨ１～Ｈ９の放射トラフ４０に供給される。水平部３０ｃの壁部材３２が設けられている領域においては、壁部材３２により物品の排出が規制されるため、分散テーブル３０上から物品は排出されない。そのため、ヘッドＨ９に向かって分散テーブル３０上を上流から搬送されてきた物品のうち、ヘッドＨ９の放射トラフ４０に供給されなかった余剰の物品は、水平部３０ｃの壁部材３２が設けられている領域を通過し、ヘッドＨ１に向かって搬送される。つまり、水平部３０ｃの、分散テーブル３０の中心３０ａ周りの壁部材３２が配置されている角度領域は、ヘッドＨ９からヘッドＨ１に向けての物品の循環路として機能する。 Specifically, the distribution table 30 on the right side in FIG. 1 will be described as an example. In the distribution table 30 on the right side in FIG. 1, the article moves radially while circulating counterclockwise on the distribution table 30, and is supplied to the radiation troughs 40 of the heads H1 to H9. In the area where the wall member 32 of the horizontal portion 30 c is provided, the discharge of the article is regulated by the wall member 32, so that the article is not discharged from the dispersion table 30. Therefore, among the articles conveyed from the upstream on the dispersion table 30 toward the head H9, surplus articles that have not been supplied to the radiation trough 40 of the head H9 are provided with the wall member 32 of the horizontal portion 30c. It passes through the area and is conveyed toward the head H1. That is, the angular region in which the wall member 32 around the center 30a of the dispersion table 30 is arranged in the horizontal portion 30c functions as a circulation path for articles from the head H9 to the head H1.
　なお、本実施形態では、分散テーブル３０として、円錐部３０ｂを取り囲むように水平部３０ｃを有する分散テーブルが採用されているが、これに限定されるものではない。例えば、分散テーブル３０には、水平部３０ｃを有さない（つまり、全体が円錐形状の）分散テーブルが採用されてもよい。 In the present embodiment, a dispersion table having a horizontal portion 30c so as to surround the conical portion 30b is adopted as the dispersion table 30, but the present invention is not limited to this.

　（３）組合せ計量装置の全体動作の概略
　組合せ計量装置１００の上流側のコンベア（図示せず）から物品振分部２００に供給された物品は、物品振分部２００により、物品供給部１０の２つの供給トラフ１１に振り分けられる。各供給トラフ１１に振り分けられた物品は、供給トラフ１１が供給トラフ加振部２０によりリニア振動させられることで、その供給トラフ１１の物品搬送先の分散テーブル３０へと搬送される。供給トラフ１１により搬送された物品は、分散テーブル３０の中央部（分散テーブル３０の中心３０ａの近傍）に落下する。分散テーブル３０上に落下した物品は、回動する分散テーブル３０によって周方向に分散されながら、分散テーブル３０の外周縁に向って搬送され、ヘッドＨ１～Ｈ９の放射トラフ４０の内端部に供給される。放射トラフ４０は、分散テーブル３０から供給された物品を振動によって内側から外側に向けて搬送する。放射トラフ４０の外端部から排出された物品は、プールホッパ５０に供給され、そこで一時的に貯留される。プールホッパ５０から排出された物品は、計量ホッパ６０に供給される。計量ホッパ６０に供給された物品は、計量ホッパ６０内に一時的に貯留され、ロードセル６３によって重量が計量される。計量ホッパ６０から排出された物品は、ブースタホッパ７０に供給される。制御部９０は、ロードセル６３から物品の計量値を受け付け、計量ホッパ６０内の物品の重量およびブースタホッパ７０に一時貯留される物品の重量を基に組合せ演算を行う。そして、制御部９０は、組合せ演算の結果が、所定の許容範囲内で、かつ、最も目標値に近くなるホッパの組合せを選択し、選択された組合せに含まれるホッパから物品を排出させる。ブースタホッパ７０から排出された物品は、集合排出シュート８０に集合させられて、集合排出シュート８０の排出口８１から製袋包装機３００に向けて排出される。 (3) Overview of Overall Operation of Combination Weighing Device Articles supplied to the article distribution unit 200 from a conveyor (not shown) on the upstream side of the combination weighing device 100 are stored in the article supply unit 10 by the article distribution unit 200. The two supply troughs 11 are distributed. The articles distributed to the supply troughs 11 are conveyed to the distribution table 30 at the article conveyance destination of the supply troughs 11 when the supply troughs 11 are linearly vibrated by the supply trough vibration unit 20. The article conveyed by the supply trough 11 falls to the center of the dispersion table 30 (near the center 30a of the dispersion table 30). The article dropped on the dispersion table 30 is conveyed toward the outer peripheral edge of the dispersion table 30 while being distributed in the circumferential direction by the rotating dispersion table 30, and is supplied to the inner ends of the radiation troughs 40 of the heads H1 to H9. Is done. The radiation trough 40 conveys the articles supplied from the dispersion table 30 from the inside to the outside by vibration. The articles discharged from the outer end of the radiation trough 40 are supplied to the pool hopper 50 and temporarily stored there. The articles discharged from the pool hopper 50 are supplied to the weighing hopper 60.

The control unit 90 receives the weighing value of the article from the load cell 63 and performs a combination calculation based on the weight of the article in the weighing hopper 60 and the weight of the article temporarily stored in the booster hopper 70. Then, the control unit 90 selects a combination of hoppers whose combination calculation result is within a predetermined allowable range and is closest to the target value, and discharges articles from the hoppers included in the selected combination. The articles discharged from the booster hopper 70 are collected in the collective discharge chute 80 and discharged from the discharge port 81 of the collective discharge chute 80 toward the bag making and packaging machine 300.
　（４）供給トラフの振動強度の制御
　供給トラフ加振部２０による、供給トラフ１１の振動強度の制御について説明する。 (4) Control of vibration intensity of supply trough The control of the vibration intensity of the supply trough 11 by the supply trough vibration unit 20 will be described.
　供給トラフ１１の振動強度、言い換えれば、供給トラフ１１の振動強度を決定する、その供給トラフ１１に対応する供給トラフ加振部２０のコイル２７の第１電磁石２７ａおよび第２電磁石２７ｂの導線に印加される電圧、および／又は、導線に流れる電流の大きさは、その供給トラフ１１の物品の搬送先の分散テーブル３０に設けられた分散部ロードセル３３の計量値（分散テーブル３０上の物品の積載量）に基づいて制御される。 The vibration intensity of the supply trough 11, in other words, the vibration intensity of the supply trough 11, is applied to the conducting wires of the first electromagnet 27a and the second electromagnet 27b of the coil 27 of the supply trough vibration unit 20 corresponding to the supply trough 11. The magnitude of the applied voltage and / or the current flowing through the conductor is determined by the weight value of the distribution unit load cell 33 provided on the distribution table 30 of the supply destination of the articles of the supply trough 11 (the loading of the articles on the distribution table 30). Amount).
　つまり、ここでは、制御部９０は、供給トラフ１１の振動のＯｎ／Ｏｆｆを制御するだけではなく、供給トラフ１１の振動強度を決定する、供給トラフ加振部２０のコイル２７の第１電磁石２７ａおよび第２電磁石２７ｂの導線に印加される電圧、および／又は、導線に流れる電流を制御することで、分散テーブル３０に供給される物品の量を精度よく制御している。 That is, here, the control unit 90 not only controls On / Off of the vibration of the supply trough 11, but also determines the vibration intensity of the supply trough 11, and the first electromagnet 27a of the coil 27 of the supply trough vibration unit 20. And the quantity of the articles | goods supplied to the dispersion | distribution table 30 is accurately controlled by controlling the voltage applied to the conducting wire of the 2nd electromagnet 27b, and / or the electric current which flows into a conducting wire.
　具体的には、制御部９０は、分散テーブル３０上の物品の重量の所定の目標値に対して、分散部ロードセル３３により計量された物品の重量が小さい場合には、供給トラフ１１の振動強度が大きくなるよう供給トラフ加振部２０（導線を流れる電流や印加電圧の値）を制御する。また、制御部９０は、分散テーブル３０上の物品の重量の所定の目標値に対して、分散部ロードセル３３により計量された物品の重量が大きい場合には、供給トラフ１１の振動強度が小さくなるよう供給トラフ加振部２０を制御する。なお、導線を流れる電流や印加電圧の値は、重量の目標値と計量値との乖離の大きさに応じて決定される。 Specifically, the control unit 90 determines the vibration intensity of the supply trough 11 when the weight of the article measured by the dispersion unit load cell 33 is smaller than the predetermined target value of the weight of the article on the dispersion table 30. The supply trough vibration unit 20 (the value of the current flowing through the conducting wire and the value of the applied voltage) is controlled so as to increase. Further, the control unit 90 reduces the vibration intensity of the supply trough 11 when the weight of the article weighed by the dispersion unit load cell 33 is larger than the predetermined target value of the weight of the article on the dispersion table 30. The supply trough vibration unit 20 is controlled. In addition, the value of the electric current which flows through a conducting wire, and the applied voltage is determined according to the magnitude | size of the deviation of the target value of weight, and a measured value.
　なお、供給トラフ１１上の物品の量は、各供給トラフ１１に設けられた供給部ロードセル１４の計量値に応じて、制御部９０により振分駆動部２２０が制御されることで、および／又は、制御部９０が上流側の図示しないコンベアに対し振分駆動部２２０への物品の搬送量の増減を要求することで、調整される。 The amount of articles on the supply troughs 11 is determined by controlling the distribution drive unit 220 by the control unit 90 according to the measurement value of the supply unit load cell 14 provided in each supply trough 11, and / or. The control unit 90 makes an adjustment by requesting an increase or decrease in the conveyance amount of the article to the distribution drive unit 220 with respect to a conveyor (not shown) on the upstream side.
　（５）特徴
　（５－１）
　本実施形態に係る組合せ計量装置１００は、２つの分散テーブル３０と、供給手段の一例としての物品供給部１０と、を備える。分散テーブル３０は、回動して、上部に供給される物品を周方向に分散させる。物品供給部１０は、上面視において２つの分散テーブル３０の間に配置され、２つの分散テーブル３０に物品を供給する。物品供給部１０は、物品を搬送する２つの供給トラフ１１と、２つの供給トラフ加振部２０と、を有する。２つの供給トラフ加振部２０は、それぞれが供給トラフ１１の一方に対応し、対応する供給トラフ１１をリニア振動させる。分散テーブル３０の一方へと物品を搬送する供給トラフ１１の一方と、分散テーブル３０の他方へと物品を搬送する供給トラフ１１の他方とは、互いの背面（背面壁１１ｂ）同士が隣接するように配置される。 (5) Features (5-1)
The combination weighing device 100 according to the present embodiment includes two distribution tables 30 and an article supply unit 10 as an example of a supply unit. The dispersion table 30 rotates to disperse articles supplied to the upper part in the circumferential direction. The article supply unit 10 is disposed between the two distribution tables 30 in a top view and supplies articles to the two distribution tables 30. The article supply unit 10 includes two supply troughs 11 for conveying articles and two supply trough vibration units 20. Each of the two supply trough vibration units 20 corresponds to one of the supply troughs 11 and linearly vibrates the corresponding supply trough 11. One of the supply troughs 11 that convey the articles to one side of the dispersion table 30 and the other of the supply troughs 11 that convey the articles to the other side of the dispersion table 30 are so that their back surfaces (back wall 11b) are adjacent to each other. Placed in.
　本実施形態に係る組合せ計量装置１００では、供給トラフ１１が、回転振動ではなく、リニア振動させられるため、供給トラフ１１により物品を安定して搬送することが容易で、供給トラフ１１による物品の搬送量不足を抑制することが可能である。 In the combination weighing device 100 according to the present embodiment, since the supply trough 11 is linearly oscillated instead of rotating, it is easy to stably convey the article by the supply trough 11, and the article is conveyed by the supply trough 11. It is possible to suppress the shortage.
　（５－２）
　本実施形態に係る組合せ計量装置１００では、供給トラフ加振部２０のそれぞれは、対応する供給トラフ１１の搬送方向Ｄ１と直交する、対応する供給トラフ１１の幅方向に、互いに間隔を空けて並べられた、複数のコイル２７を有する。 (5-2)
In the combination weighing device 100 according to the present embodiment, each of the supply trough vibration units 20 is arranged at intervals in the width direction of the corresponding supply trough 11 that is orthogonal to the conveyance direction D1 of the corresponding supply trough 11. The plurality of coils 27 are provided.
　長さの短い供給トラフ１１を用いつつ、分散テーブル３０への物品供給量を十分に確保するためには、供給トラフ１１に振動を発生させる電磁フィーダのコイルを大型化し、供給トラフ１１の振幅を大きくするという対応が考えられる。しかし、コイルを大型化した場合には、コイルの放熱性が悪化するという別の問題が生じる。 In order to ensure a sufficient supply amount of articles to the dispersion table 30 while using the short supply trough 11, the coil of the electromagnetic feeder that generates vibration in the supply trough 11 is enlarged, and the amplitude of the supply trough 11 is increased. A possible response is to increase it. However, when the coil is enlarged, another problem that the heat dissipation of the coil is deteriorated occurs.
　これに対し、本実施形態に係る組合せ計量装置１００では、各供給トラフ加振部２０が、対応する供給トラフ１１の幅方向に複数のコイル２７を有することで、供給トラフ１１による物品の搬送量を大きく確保することを可能としている。また、ここでは、複数のコイル２７を有することで、１つの大きなコイルを用いる場合に比べて表面積を大きく確保することができ、さらに複数のコイル２７は空気が通る隙間Ｃを確保するように互いに間隔を空けて並べられていることから、１つの大きなコイルを有する場合に比べてコイル２７の放熱性を良好に保つことができる。 On the other hand, in the combination weighing device 100 according to the present embodiment, each supply trough vibration unit 20 includes a plurality of coils 27 in the width direction of the corresponding supply trough 11 so that the amount of articles conveyed by the supply trough 11 is increased. It is possible to secure a large amount. Further, here, by having a plurality of coils 27, it is possible to ensure a larger surface area than when one large coil is used, and furthermore, the plurality of coils 27 are mutually connected so as to ensure a gap C through which air passes. Since they are arranged at intervals, the heat dissipation of the coil 27 can be maintained better than when one large coil is provided.
　（５－３）
　本実施形態に係る組合せ計量装置１００では、各供給トラフ加振部２０のコイル２７のそれぞれは、該供給トラフ加振部２０に対応する供給トラフ１１側に向けられ、該供給トラフ加振部２０に対応する供給トラフ１１の搬送方向Ｄ１に並ぶ、Ｎ極およびＳ極を有する。 (5-3)
