　特許文献１は、多少の衝撃によって曲がったり折れたりすることのない硬めの棒状物品を組合せ計量の対象とするものであり、例えば、鱈のすり身を主原料とする乾燥シートの間にチーズを挟んで細長く切断したチーズタラあるいはジャーキー等の比較的柔らかくて細長い物品に適用するのは困難である。すなわち、特許文献１の装置で、比較的柔らかくて細長い物品を計量しようとすると、最終段のガイド筒に縦姿勢で落下収容される際に、その落下衝撃によって物品が曲がったり折れたりするおそれがある。このため、計量した物品を整列した状態で好適に排出するのは難しい。 Patent Literature 1 aims at combination weighing of a hard rod-shaped article that does not bend or break due to a slight impact, for example, sandwiching cheese between dried sheets mainly made of cod surimi. It is difficult to apply it to relatively soft and elongated articles such as cheese cod or jerky which has been cut into an elongated shape. That is, when the device of Patent Document 1 is used to measure a relatively soft and slender article, the article may be bent or broken by the drop impact when the article is dropped and accommodated in a vertical position in the final guide tube. is there. Therefore, it is difficult to properly discharge the weighed articles in an aligned state.
　特に、チーズタラ等の食品は、外部から目視可能に透明な包装袋等に封止されて販売されることが多く、曲がったり折れたりしたものが混じっていると商品価値が下ってしまう。 In particular, food products such as cheese cod are often sold in a transparent packaging bag or the like so that they can be seen from the outside, and the merchandise value decreases if bent or broken foods are mixed.
　また、特許文献２も、スティックパンのような硬めの棒状物品を対象とするものであり、比較的柔らかくて細長い物品を整列させて排出するのは困難である。すなわち、チーズタラのように比較的柔らかく、かつ、湿り気があって滑り抵抗が大きい細長い物品を、下方へ向かって狭まりながら延びるスロートを有する配列用シュートに沿って滑落移動させながら整列させて姿勢変更するのは難しい。 特許 Also, Patent Document 2 is directed to a hard bar-shaped article such as a stick pan, and it is difficult to align and discharge relatively soft and elongated articles. In other words, the posture is changed by aligning and sliding a relatively soft, moist and long slip-resistant article, such as a cheese cod, while sliding down along an arraying chute having a throat extending narrowing downward. Difficult.
　このため、従来より、チーズタラのような柔らかい細長い物品の計量包装は、人手によって行われている。具体的には、作業者がトレー上に物品を整列させて載せると共に、台秤等で計量し、包装材に載荷あるいは挿入して包装材をシールするといったように、計量、整列及び包装を手作業で行っている。 For this reason, conventionally, weighing and packaging of a soft and elongated article such as cheese cod has been performed manually. Specifically, the operator manually arranges and places the articles on the tray, weighs them with a platform scale, etc., and loads or inserts them into the packaging material to seal the packaging material, so that the weighing, alignment, and packaging are performed manually. It is done in.

It is a schematic side view which shows a measuring device typically.
　なお、以下においては、説明の便宜上、図２における左右方向、及び、図３における紙面表裏方向を左右方向と呼称し、図２における紙面表裏方向、及び、図３における左右方向を前後方向と呼称することにする。 In the following, for convenience of explanation, the left-right direction in FIG. 2 and the front-back direction in FIG. 3 are referred to as left-right direction, and the front-back direction in FIG. 2 and the left-right direction in FIG. I will do it.
　この実施形態の組合せ計量装置は、例えば、鱈のすり身を主原料とする乾燥シートの間にチーズを挟んで細長く切断したチーズタラあるいはジャーキーなどの比較的柔らかくて細長い物品を計量して搬出するのに好適な組合せ計量装置である。この組合せ計量装置は、チーズタラ等の物品を組合せ計量して排出する組合せ秤１と、組合せ秤１から排出された物品を横一側方（この例では左方）へ搬送すると共に、集合整列させて搬出する集合整列搬出装置２とを備えている。 The combination weighing device of this embodiment is, for example, for weighing and discharging relatively soft and slender articles such as cheese cod or jerky which is cut into strips with cheese sandwiched between dried sheets whose main raw material is cod surimi. It is a suitable combination weighing device. This combination weighing apparatus combines a combination weigher 1 that weighs and discharges articles such as cheese cod, and conveys the articles discharged from the combination weigher 1 to one side (left side in this example) and collects and aligns them. And a set sorting / unloading device 2 for unloading.
　上部に配置されている組合せ秤１は、物品を左右方向に並列した多数系統、この例では１４系統の整列搬送径路で前方へ搬送しながら整列させる整列供給部３と、整列供給部３の各整列搬送径路から搬送されてきた物品を受け取るように、一方向、この例では、横方向に沿って並んで配置された多数連（この例では１４連）の計量ユニット４とを備えている。 The combination weigher 1 disposed at the upper part includes an alignment supply unit 3 for arranging articles while transporting them forward along a multiplicity of systems in which the articles are arranged in a horizontal direction, in this example, 14 alignment conveyance paths. In order to receive the articles conveyed from the aligned conveyance path, a plurality of (in this example, 14) weighing units 4 are arranged side by side in one direction, in this example, in the lateral direction.
　整列供給部３における一つの整列搬送径路は、３台の直進フィーダ５を、物品の搬送方向に沿って前下がり階段状に縦列配置して構成されている。各整列搬送径路で搬送された物品は、対応する各計量ユニット４にそれぞれ供給される。 (1) One alignment conveyance path in the alignment supply section 3 is configured by arranging three straight-ahead feeders 5 in a stepwise manner in a forward-downward direction along the article conveyance direction. The articles conveyed in each alignment conveyance path are supplied to each corresponding weighing unit 4.
　各計量ユニット４は、整列供給部３における各整列搬送径路で搬送されてきた物品を受け取って一時保持する供給ホッパ６と、供給ホッパ６から排出された物品ｗを受け取ってその重量を計測する計量ホッパ７とを備えている。この実施形態では、各ホッパ６，７は、図示していないが、物品との摩擦を低減するためにエンボス加工が施されている。 Each weighing unit 4 receives a supply hopper 6 that receives and temporarily holds the articles conveyed on each of the alignment conveyance paths in the alignment supply section 3, and a weighing unit that receives the articles w discharged from the supply hopper 6 and measures the weight thereof. And a hopper 7. In this embodiment, although not shown, each hopper 6, 7 is embossed in order to reduce friction with an article.
　組合せ秤１では、従来と同様に組合せ計量を行う。すなわち、組合せ秤１の制御装置（図示せず）は、複数の計量ホッパ７で計量された物品の重量を種々に組合せた組合せ重量が、目標組合せ重量に等しい又は目標組合せ重量に最も近い所定重量範囲となる計量ホッパ７の組合せである適量組合せを選択する組合せ演算を行う。この組合せ演算で適量組合せとして選択した計量ホッパ７の物品ｗを下方へ排出する。 The combination weigher 1 performs combination weighing in the same manner as in the related art. That is, the control device (not shown) of the combination weigher 1 determines that the combination weight obtained by variously combining the weights of the articles weighed by the plurality of weighing hoppers 7 is equal to or closest to the target combination weight. A combination calculation is performed to select an appropriate combination that is a combination of the weighing hoppers 7 within the range. The articles w of the weighing hopper 7 selected as the appropriate quantity combination by this combination calculation are discharged downward.
　計量ホッパ７には、図３に示すように、それぞれ独立に互いに反対方向に開閉する前後一対のゲート７ａ，７ｂが備えられている。これらゲート７ａ，７ｂのいずれか一方７ａ（７ｂ）を、選択して開放作動させることによって、保持した物品を前後２系統の径路で排出できるようになっている。 As shown in FIG. 3, the weighing hopper 7 is provided with a pair of front and rear gates 7a and 7b which open and close independently in opposite directions. By selectively opening one of the gates 7a and 7b 7a (7b), the held articles can be discharged through two front and rear paths.
　 図４～図７は、整列供給部３を構成する直進フィーダ５の構造を示す図である。３台の直進フィーダ５の内、上段及び中段の直進フィーダ５の構造は同じであるので、図４～図６では、上段の直進フィーダ５を代表的に示す。また、図６，図７及び後述の図９では、１個の物品ｗのみを代表的に示している。 FIGS. 4 to 7 are views showing the structure of the straight-ahead feeder 5 constituting the alignment supply unit 3. FIG. Since the structure of the upper and middle linear feeders 5 among the three linear feeders 5 is the same, FIGS. 4 to 6 show the upper linear feeder 5 as a representative. 6 and 7 and FIG. 9 described later, only one article w is representatively shown.
　図４は、物品の搬送方向の最も上手側である上段の直進フィーダ５を示す縦断側面図であり、図５は、その搬送方向の終端部を拡大した縦断側面図であり、図６は、その斜視図である。図７は、３台の直進フィーダ５の内、物品の搬送方向の最も下手側である下段の直進フィーダ５の斜視図である。 FIG. 4 is a vertical sectional side view showing the uppermost linear feeder 5 which is the uppermost side in the transport direction of the article. FIG. 5 is a vertical sectional side view in which the terminal end in the transport direction is enlarged. It is the perspective view. FIG. 7 is a perspective view of the lower straight feeder 5 which is the lowermost side in the article conveying direction among the three straight feeders 5.
　各段の直進フィーダ５は、いずれも底板の幅方向の両端から一対の側板がそれぞれ立設された搬送トラフ１０と、この搬送トラフ１０の底板の下面に連結板１１とを備えた構造となっている。この連結板１１を、図４に示すように、加振機１２の振動ヘッド部１２ａに位置決め係止して、バックル形の締結具１３で脱着可能に連結するようになっている。 Each of the linear feeders 5 of each stage has a structure including a transport trough 10 having a pair of side plates erected from both ends in the width direction of the bottom plate, and a connecting plate 11 on the lower surface of the bottom plate of the transport trough 10. ing. As shown in FIG. 4, the connection plate 11 is positioned and locked on a vibration head portion 12a of a vibrator 12, and is detachably connected by a buckle-shaped fastener 13.
　 また、搬送トラフ１０の搬送面である底面１０ａは、物品ｗの搬送方向（前後方向）に、ピッチが例えば、１５ｍｍ程度、深さが例えば、２ｍｍ程度の連続した波型に形成されている。この底面１０ａの波型のピッチは、１個の物品ｗが波型の窪みに入り込んで横向きとなるように、１個の物品ｗの幅に対応したピッチとなっている。 The bottom surface 10a, which is the transport surface of the transport trough 10, is formed in a continuous wave shape having a pitch of, for example, about 15 mm and a depth of, for example, about 2 mm, in the transport direction (front-back direction) of the article w. The corrugated pitch of the bottom surface 10a is a pitch corresponding to the width of one article w such that one article w enters the corrugated recess and becomes horizontal.
　搬送トラフ１０の底面１０ａに載置された細長い物品ｗは、加振されることによって波型に沿った横向き姿勢、すなわち、その長手方向が、物品ｗの搬送方向に直交する姿勢に整列されながら、前方に振動搬送されるようになっている。つまり、細長い物品ｗは、搬送トラフ１０によって振動搬送されながら、搬送方向に一定ピッチで連続する波型の凹部と凸部とを繰り返し通過することで、波型に沿った横向き姿勢に整列されて搬送される。 The elongated article w placed on the bottom surface 10a of the transport trough 10 is laterally oriented along the waveform by being vibrated, that is, while its longitudinal direction is aligned in an attitude orthogonal to the transport direction of the article w. , And is conveyed forward by vibration. In other words, while the elongated article w is vibrated and conveyed by the conveying trough 10, it repeatedly passes through the corrugated concave portions and convex portions that are continuous at a constant pitch in the conveying direction, and is aligned in a horizontal posture along the corrugated shape. Conveyed.
　搬送トラフ１０による物品ｗの搬送方向は、前方であり、複数の計量ユニット４の配列方向は横方向であるので、物品ｗの搬送方向に直交する方向は、複数の計量ユニット４の配列方向である横方向となる。したがって、搬送トラフ１０によって、物品ｗは、その長手方向が複数の計量ユニット４の配列方向である横方向に整列されながら振動搬送される。 The transport direction of the articles w by the transport trough 10 is forward, and the arrangement direction of the plurality of weighing units 4 is the horizontal direction. Therefore, the direction orthogonal to the transport direction of the articles w is the arrangement direction of the plurality of weighing units 4. Some horizontal direction. Therefore, the article w is vibrated and conveyed by the conveying trough 10 while its longitudinal direction is aligned in the lateral direction which is the arrangement direction of the plurality of weighing units 4.
　上段及び中段の直進フィーダ５における搬送トラフ１０は、その底面１０ａの先端側が、前下がり傾斜されると共に、物品の搬送移動を抑制する移動抑制板１４が設けられている。この移動抑制板１４は、物品ｗを横向き姿勢で安定載置できる幅広の平板材からなる。この移動抑制板１４は、搬送トラフ１０の底面１０ａから搬送方向に水平に延出され、その先端部に、上方に向けて少し起立傾斜された傾斜立上がり部１４ａを備えている。 The transport trough 10 in the upper and middle straight feeders 5 has a bottom surface 10a whose front end side is inclined forward and downward, and is provided with a movement suppressing plate 14 for suppressing the transfer movement of articles. The movement suppressing plate 14 is made of a wide flat plate material on which the article w can be stably placed in a horizontal position. The movement restraining plate 14 extends horizontally from the bottom surface 10a of the transport trough 10 in the transport direction, and has an inclined rising portion 14a which is slightly upwardly inclined at the front end thereof.
　従って、波型の底面１０ａで振動搬送されてきた物品ｗは、移動抑制板１４上に押し込まれた後、後続の物品ｗに押されて移動抑制板１４上を移動し、終端部の傾斜立上がり部１４ａにおいて移動が抑制され、引き続く押出し搬送によって物品は傾斜立上がり部１４ａを乗り越えて少量ずつ搬出されてゆく。このように、移動抑制板１４は、適度の搬送抵抗を横向き姿勢の物品ｗに与えて、トラフ終端から多量の物品ｗが一挙に送出されて姿勢が崩れるのを抑制する。また、搬出される直前に、物品に搬送抵抗を与えることによって、整列が不十分な物品の姿勢を整える効果もある。 Therefore, the article w vibrated and conveyed on the corrugated bottom surface 10a is pushed onto the movement suppressing plate 14, and then pushed by the following article w to move on the movement suppressing plate 14, and the terminal end rises inclining. The movement is suppressed in the portion 14a, and the article is carried out little by little over the inclined rising portion 14a by the subsequent extrusion conveyance. In this manner, the movement suppressing plate 14 applies an appropriate conveyance resistance to the articles w in the lateral orientation, and suppresses a large amount of articles w from being sent from the end of the trough at once, and the orientation is suppressed. Immediately before being carried out, by imparting conveyance resistance to the articles, there is also an effect of adjusting the posture of the articles that are not sufficiently aligned.
　なお、移動抑制板１４は、平板状に限らず、櫛歯状などであってもよい。 Note that the movement suppressing plate 14 is not limited to a flat plate shape, but may be a comb tooth shape or the like.

　上段の直進フィーダ５の始端に供給された物品ｗは、先ず、直進フィーダ５の振動搬送作用を受け、搬送トラフ１０の底面１０ａの波型に沿った姿勢、つまり、横向き姿勢に整列されながら前方へ送られる。上段の直進フィーダ５の搬送トラフ１０の終端部に到達した物品ｗは、横向き姿勢を保ちながら移動抑制板１４を乗り越えて中段の直進フィーダ５に移載される。中段の直進フィーダ５においても同様に搬送トラフ１０の底面１０ａの波型に沿った横向き姿勢に整列されなきがら前方へ送られて下段の直進フィーダ５に送り込まれる。 The article w supplied to the start end of the upper straight feeder 5 is first subjected to the vibration conveying action of the straight feeder 5, and is aligned with the wave shape of the bottom surface 10a of the transfer trough 10, that is, while being aligned in the horizontal position, Sent to The article w which has reached the terminal end of the transport trough 10 of the upper straight feeder 5 is transferred to the middle straight feeder 5 over the movement suppressing plate 14 while maintaining the horizontal posture. Similarly, the middle straight feeder 5 is sent forward to the lower straight feeder 5 without being aligned in a horizontal position along the waveform of the bottom surface 10 a of the transport trough 10.
　下段の直進フィーダ５においては、横向き姿勢に整列されながら前方へ送られて、搬送トラフ用シャッタ１５に受止め保持される。 に お い て In the lower straight feeder 5, the sheet is fed forward while being aligned in the horizontal position, and is received and held by the transport trough shutter 15.
　計量ユニット４における供給ホッパ６が空になると、搬送トラフ用シャッタ１５が所定時間だけ開放制御され、少量の物品が横向き姿勢で供給ホッパ６に供給される。そして、計量ホッパ７で計量され、組合せ演算によって適量組合せとして選択された計量ホッパ７から物品ｗが排出されて空になると、供給ホッパ６が開放されて計量ホッパ７へ新たな物品ｗが供給される。 When the supply hopper 6 in the weighing unit 4 becomes empty, the transport trough shutter 15 is controlled to open for a predetermined time, and a small amount of articles is supplied to the supply hopper 6 in a horizontal position. Then, when the articles w are discharged from the weighing hopper 7 weighed by the weighing hopper 7 and selected as a proper combination by the combination calculation and become empty, the supply hopper 6 is opened and a new article w is supplied to the weighing hopper 7. You.
　組合せ演算によって所定重量範囲の適量組合せに選択された複数の計量ホッパ７におけるゲート７ａ、７ｂのいずれか一方７ａ（７ｂ）が選択的に開放制御され、所定重量範囲となる物品ｗが、前方あるいは後方の排出径路に落下排出される。計量ホッパ７から落下排出される複数の物品ｗの整列状態は大きく崩れておらず、略横向き姿勢のまま落下排出される。 Either one of the gates 7a, 7b (7b) of the plurality of weighing hoppers 7 selected in the proper amount combination within the predetermined weight range by the combination operation is selectively opened and controlled, and the article w having the predetermined weight range is moved forward or forward. It is dropped and discharged to the rear discharge path. The alignment state of the plurality of articles w dropped and discharged from the weighing hopper 7 is not largely collapsed, and the articles w are dropped and discharged in a substantially horizontal posture.
　計量ホッパ７から物品が落下排出される時には、計量ホッパ７からの物品の排出経路である前側及び後側の搬送コンベヤ２１の少なくともいずれか一方の搬送コンベヤ２１が、物品の受取り位置（ａ）に在る。計量ホッパ７から排出された物品ｗは、受取り位置（ａ）に在る搬送コンベヤ２１における搬送方向の複数個所に、物品長手方向が、搬送コンベヤ２１の搬送方向に略沿った横向き姿勢で落下供給される。 When articles are dropped and discharged from the weighing hopper 7, at least one of the front and rear transport conveyors 21, which are the discharge paths of the articles from the weighing hopper 7, is moved to the article receiving position (a). exist. The articles w discharged from the weighing hopper 7 are dropped and supplied at a plurality of locations in the transport direction of the transport conveyor 21 located at the receiving position (a) with the longitudinal direction of the articles in a horizontal position substantially along the transport direction of the transport conveyor 21. Is done.
　物品ｗを受け取った搬送コンベヤ２１は、集合トラフ２５の状況に応じて、受取り位置（ａ）、あるいは、退避位置（ｂ）のいずれかを物品の搬出位置として選択し、搬送コンベヤ２１毎に前後２系統の搬出位置に対応して配置された集合トラフ２５に向けての搬送が行われる。計量ホッパ７から排出されて、搬送コンベヤ２１の搬送方向の複数個所に落下供給された物品ｗの全量が、集合トラフ２５に投入されることで、集合トラフ２５に所定重量範囲の物品ｗが搬入収容される。 The conveyor 21 having received the article w selects either the receiving position (a) or the retreat position (b) as the article unloading position according to the condition of the collecting trough 25, and moves forward and backward for each conveyor 21. The transport is performed toward the collective trough 25 arranged corresponding to the two systems of unloading positions. The entire amount of the articles w discharged from the weighing hopper 7 and dropped and supplied to a plurality of locations in the transport direction of the transport conveyor 21 is thrown into the collective trough 25, so that the articles w of a predetermined weight range are carried into the collective trough 25. Will be accommodated.
　基本的には、計量ホッパ７からの所定重量範囲の物品の排出は、前側の搬送コンベヤ２１及び後側の搬送コンベヤ２１に対して交互に行われる。また、各搬送コンベヤ２１による、受取り位置（ａ）に対応する集合トラフ２５、及び、退避位置（ｂ）に対応する集合トラフ２５に対する所定重量範囲の物品の搬出も基本的には交互に行われる。 Basically, the discharge of articles in a predetermined weight range from the weighing hopper 7 is performed alternately on the front conveyor 21 and the rear conveyor 21. In addition, each transport conveyor 21 also basically alternately carries out articles in a predetermined weight range to the collecting trough 25 corresponding to the receiving position (a) and the collecting trough 25 corresponding to the retreat position (b). .
　以上の動作が４つの集合トラフ２５における物品排出状況に応じて繰り返される。これによって、前後２台の搬送コンベヤ２１による４つの集合トラフ２５への所定重量範囲の物品の搬送が順次実行される。 動作 The above operation is repeated according to the article discharge status in the four collective troughs 25. As a result, the transfer of articles in a predetermined weight range to the four collecting troughs 25 by the two front and rear transfer conveyors 21 is sequentially performed.
　集合トラフ２５に投入された所定重量範囲の物品ｗは、窪んで湾曲した底面の長手方向に沿った姿勢で振動搬送作用を受け、互いに平行に整列されながら搬送され、集合トラフ用シャッタ２９に受止められる。また、搬送コンベヤ２１からの物品投入時点では、プッシャー３３は、物品投入を妨げない位置に退避している。物品投入が完了すると、プッシャー３３は、低速で、図８に示される所定位置（ｃ）までの進出と後退を所定回数繰り返し、振動搬送作用を受けている物品ｗの後端を軽くたたくように押圧して後端揃えを行って前記所定位置（ｃ）で待機する。なお、物品ｗの後端揃えを行ってプッシャー３３が待機する所定位置（ｃ）は、集合トラフ用シャッタ２９で受止められて積層された物品ｗの後端位置よりも若干後方の位置であり、集合トラフ用シャッタ２９で受止められた物品ｗの後端を無理に押圧するようなことはない。 The articles w in the predetermined weight range put into the collective trough 25 are subjected to a vibrating and conveying action in a posture along the longitudinal direction of the concave and curved bottom surface, conveyed while being aligned in parallel with each other, and received by the collective trough shutter 29. Can be stopped. At the time of loading the articles from the conveyor 21, the pusher 33 is retracted to a position where the loading of the articles is not hindered. When the article introduction is completed, the pusher 33 repeats advancing and retreating to the predetermined position (c) shown in FIG. 8 a predetermined number of times at a low speed, and taps the rear end of the article w being subjected to the vibration conveyance action. Press to align the rear end and wait at the predetermined position (c). The predetermined position (c) at which the rear end of the articles w is aligned and the pusher 33 waits is a position slightly behind the rear end position of the articles w received and stacked by the collective trough shutter 29. Therefore, the rear end of the article w received by the collective trough shutter 29 is not forcibly pressed.
　集合トラフ用シャッタ２９が開放されると、これに連動してプッシャー３３が前記待機位置から更に高速で進出作動し、整列された所定重量範囲の物品ｗを一挙に集合トラフ２５から押出し排出する。 (4) When the collective trough shutter 29 is opened, the pusher 33 moves out of the standby position at a higher speed in conjunction with the opening, and pushes out the aligned articles in a predetermined weight range from the collective trough 25 at once.
　なお、４つの集合トラフ２５から排出される物品ｗは、適宜手段によって包装工程に搬送される。例えば、集合トラフ２５の排出箇所に、ロボットアーム等に支持されたトレー状の搬送具を待機させ、集合トラフ２５から整列状態で排出された物品ｗを搬送具で受け取る。次に、搬送具を包装容器のコンベヤラインに移動させ、一定ピッチで搬送されてくる包装容器に搬送具から物品を移載装填し、その後、物品が収容された包装容器を封止工程に送る、等の処理がなされる。 The articles w discharged from the four collecting troughs 25 are conveyed to the packaging step by appropriate means. For example, a tray-shaped carrier supported by a robot arm or the like is made to stand by at a discharge point of the collective trough 25, and the articles w discharged in an aligned state from the collective trough 25 are received by the carrier. Next, the transporting tool is moved to the conveyor line of the packaging container, the articles are transferred and loaded from the transporting tool to the packaging container that is transported at a constant pitch, and then the packaging container containing the article is sent to the sealing process. , Etc. are performed.
　前記搬送コンベヤ２１は、逆転可能に構成されている。例えば、計量ホッパ７に、適量組合せに選択されにくい過量の物品が供給されたような場合には、その計量ホッパ７から過量の物品を搬送コンベヤ２１に排出し、搬送コンベヤ２１を逆転駆動する。これによって、過量の物品を、図１に示される、集合トラフ２５とは反対側に配置された回収ボックス３５へ排出する。 搬 送 The conveyor 21 is configured to be reversible. For example, when an excessive amount of articles that are difficult to be selected as an appropriate combination is supplied to the weighing hopper 7, the excessive amount of articles is discharged from the weighing hopper 7 to the transport conveyor 21, and the transport conveyor 21 is driven in reverse. Thereby, the excessive amount of articles is discharged to the collection box 35 shown in FIG.
　 本実施形態では、３段の直進フィーダ５によって、物品ｗは、その長手方向が、複数の計量ユニット４の配列方向である横方向に沿うように整列されて計量ユニット４の供給ホッパ６に供給される。計量ユニット４の計量ホッパ６から排出される物品ｗは、搬送コンベヤ２１によって、前記横方向に沿って搬送されて集合トラフ２５へ投入され、集合トラフ２５によって、物品ｗは、その長手方向が前記横方向に沿うように再び整列される。 In this embodiment, the articles w are supplied to the supply hopper 6 of the weighing unit 4 by the three-stage linear feeders 5 so that the longitudinal direction thereof is aligned along the horizontal direction which is the arrangement direction of the plurality of weighing units 4. Is done. The articles w discharged from the weighing hopper 6 of the weighing unit 4 are conveyed along the lateral direction by the conveyor 21 and fed into the collecting trough 25. It is realigned along the lateral direction.
　このように、組合せ計量装置では、物品は、その長手方向が前記横方向に沿う状態で処理がそれぞれ行われるので、組合せ計量装置から搬出される際には、物品は、その長手方向が前記横方向に一層揃った整列状態で搬出される。 As described above, in the combination weighing device, the article is processed in the state where the longitudinal direction thereof is along the horizontal direction. Therefore, when the article is carried out of the combination weighing device, the longitudinal direction of the article is the horizontal direction. It is carried out in a more aligned state in the direction.
