Description

本発明は、仕分け機によって仕分けされた荷物を運ぶ二つの仕分けシュートコンベヤを合流シュートコンベヤに合流するための設置コストに有利で、しかも同じ出荷方面に荷物が集中しても連続して仕分けでき、作業効率を低下させない、仕分け荷物合流システムに関する。   The present invention is advantageous to the installation cost for joining two sort chute conveyors that carry the baggage sorted by the sorter to the merge chute conveyor, and can be sorted continuously even if the bags are concentrated in the same shipping direction, The present invention relates to a sorting and merging system that does not reduce work efficiency.

従来から、トラックターミナル等の集配所に集められた荷物は、仕分け機等によって出荷方面別に仕分けされて仕分けシュートコンベヤに引き取られた後に出荷方面行きのトラックの背後まで搬送されている。この場合、仕分け処理能力が多く必要なときはそれに応じて複数の仕分け機を設置し、同じ出荷方面に仕分けされた荷物を最終的に一つのシュートコンベヤに合流することが必要である。   2. Description of the Related Art Conventionally, packages collected at a collection place such as a truck terminal are sorted by shipping direction by a sorting machine or the like, picked up by a sorting chute conveyor, and then transported to the back of the truck for the shipping direction. In this case, when a large amount of sorting capacity is required, it is necessary to install a plurality of sorting machines accordingly and finally join the packages sorted in the same shipping direction to one chute conveyor.

かかる条件を満たした従来の仕分け荷物合流システムの一例を図１に示す。図中、１，２は同じ出荷方面に仕分けされた荷物を搬送するシュートコンベヤを表し、矢印は搬送方向を示す。このシステムでは、シュートコンベヤ１，２は互いに有効幅が等しいので、同時に荷物を合流させると荷詰まりを起こしやすい。従って、これを防ぐために、一方のシュートコンベヤ１上の荷物は優先的に流し、他方のシュートコンベヤ２上の荷物は合流部の荷物の有無を検知するセンサによってシュートコンベヤ１の合流部３に荷物がある場合はシュートコンベヤ２を停止し、合流部３の荷物の通過を確認してからシュートコンベヤ２を始動させて荷物をシュートコンベヤ１上に合流させている。具体的にはシュートコンベヤ１の合流部の上流位置に光電センサを設置し、先の荷物が通過（遮光）後、設定時間以内に次の荷物が通過（遮光）しないという条件でコンベヤ上に荷物がないと判断し、シュートコンベヤ２上の荷物をシュートコンベヤ１上へ投入する。この方法を記載した文献としては特許文献１及び特許文献２が挙げられる。   An example of a conventional sorting and merging system that satisfies such conditions is shown in FIG. In the figure, 1 and 2 represent chute conveyors for transporting packages sorted in the same shipping direction, and arrows indicate transport directions. In this system, the effective widths of the chute conveyors 1 and 2 are equal to each other. Therefore, in order to prevent this, the load on one chute conveyor 1 is preferentially flowed, and the load on the other chute conveyor 2 is loaded on the merge portion 3 of the chute conveyor 1 by a sensor that detects the presence or absence of the load at the merge portion. If there is, the chute conveyor 2 is stopped, and after the passage of the cargo in the junction 3 is confirmed, the chute conveyor 2 is started to merge the cargo onto the chute conveyor 1. Specifically, a photoelectric sensor is installed at the upstream position of the junction of the chute conveyor 1, and after the previous baggage passes (light-shielded), the next baggage does not pass (light-shielded) within the set time. The load on the chute conveyor 2 is loaded onto the chute conveyor 1. References describing this method include Patent Document 1 and Patent Document 2.

この方法は自動的に合流制御がなされるので、人手が掛からず荷物を一列に整列して直接トラックに搬送できる点で優れるが、自動合流のための制御が必要となり、設置コストが高い。また、シュートコンベヤ１上の荷物が集中する場合を想定してシュートコンベヤ２上の荷物を一時待機させるが、それ以上の荷物が仕分けされると、満杯になり、ダイバータロックして荷物を仕分け機の下流端に流すことになり、その仕分け能力を低下させることになる。そのために荷物を多く待機させるにはシュートコンベヤを分割する必要があり、やはり設置コストが高くなる。また、仕分け機の下流端に流された荷物は自動か手動で再度仕分けされなければならないので、作業効率が低下する。   Since this method automatically controls the merge, it is excellent in that the load can be arranged in a line and transported directly to the truck without manpower, but the control for automatic merge is required and the installation cost is high. In addition, assuming that the packages on the chute conveyor 1 are concentrated, the packages on the chute conveyor 2 are temporarily held. When more packages are sorted, the bag becomes full and the diverter is locked to sort the packages. It will flow to the downstream end of this, and its sorting ability will be reduced. Therefore, it is necessary to divide the chute conveyor to wait for a large amount of luggage, which also increases the installation cost. In addition, since the cargo that has flowed to the downstream end of the sorting machine has to be sorted again automatically or manually, work efficiency is reduced.

一方、図１に記載の方法と同じように二つの仕分け機を設置するが、二つのシュートコンベヤ同士は合流せずに平行に出荷方面行きトラックの背後まで進む方法がある。この仕分け荷物合流システムの一例を図２に示す。このシステムでは合流制御が不要であり、しかも待機される荷物がないため荷物をシュートコンベヤの上流端に廻す必要がない点で優れるが、二つのコンベヤが平行になった後のコンベヤの機幅が２倍になり、下流端においても２倍のスペースが必要となり、床の使用スペースが減少する。従って、仕分け処理能力が要求されて多くのシュートコンベヤが必要なレイアウトでは採用が極めて困難である。また、二つのコンベヤがそのまま平行に位置されるので、人手による荷物の整列が必要である。
特開平１１−３１４７３５号公報 実開平７−４０６３４号公報 On the other hand, two sorters are installed in the same manner as in the method shown in FIG. 1, but there is a method in which the two chute conveyors are not joined together but proceed in parallel to the back of the truck for the shipping direction. An example of this sorting luggage joining system is shown in FIG. This system is superior in that no merging control is required and there is no need to wait for the cargo to be routed to the upstream end of the chute conveyor, but the width of the conveyor after the two conveyors become parallel is excellent. Doubles and doubles the space at the downstream end, which reduces the floor usage space. Therefore, it is extremely difficult to employ a layout that requires a sorting capacity and requires a large number of chute conveyors. Further, since the two conveyors are positioned in parallel as they are, it is necessary to manually arrange the luggage.
JP 11-314735 A Japanese Utility Model Publication No. 7-40634

本発明は、かかる従来技術の現状に鑑み創案されたものであり、その目的は仕分け機によって仕分けされた荷物を運ぶ複数の仕分けシュートコンベヤを荷物の損傷を受けずにスムーズに一つの合流シュートコンベヤに合流するための安価な設置コストの仕分け荷物合流システムを提供することにある。   The present invention was devised in view of the current state of the prior art, and its purpose is to provide a plurality of sorting chute conveyors for carrying a baggage sorted by a sorting machine, smoothly without damaging the baggage.

即ち、本発明は、第一の側面によれば、仕分け機によって仕分けされた荷物を運ぶ二つの仕分けシュートコンベヤと、これらの仕分けシュートコンベヤが合流する合流シュートコンベヤとを具備する仕分け荷物合流システムにおいて、一方の仕分けシュートコンベヤが合流制御なしに合流シュートコンベヤの上流端に垂れ流し合流され、他方の仕分けコンベヤが合流制御なしに合流シュートコンベヤの側面のいずれかの位置に垂れ流し合流されていること、及び合流シュートコンベヤの有効幅が仕分けシュートコンベヤの有効幅の１．５倍以上１．９倍以下の長さであることを特徴とする仕分け荷物合流システムである。   That is, according to the first aspect of the present invention, there is provided a sorting baggage merging system comprising two sorting chute conveyors for transporting a baggage sorted by a sorting machine and a merging chute conveyor for joining these sorting chute conveyors. One of the sorting chute conveyors is dropped and joined to the upstream end of the joining chute conveyor without joining control, and the other sorting conveyor is dropped and joined to any position on the side of the joining chute conveyor without joining control; and An effective width of the merging chute conveyor is 1.5 to 1.9 times longer than an effective width of the categorizing chute conveyor.

また、本発明は、第二の側面によれば、仕分け機によって仕分けされた荷物を運ぶ二つの仕分けシュートコンベヤと、これらの仕分けシュートコンベヤが合流する合流シュートコンベヤとを具備する仕分け荷物合流システムにおいて、全ての仕分けシュートコンベヤが合流制御なしに合流シュートコンベヤの側面のいずれかの位置に垂れ流し合流されていること、及び合流シュートコンベヤの有効幅が仕分けコンベヤシュートの有効幅の１．５倍以上１．９倍以下の長さであることを特徴とする仕分け荷物合流システムである。   According to a second aspect of the present invention, there is provided a sorting baggage merging system comprising two sorting chute conveyors for transporting a baggage sorted by a sorting machine, and a merging chute conveyor for joining these sorting chute conveyors. , All sorting chute conveyors are dropped and joined to any position on the side of the joining chute conveyor without joining control, and the effective width of the joining chute conveyor is 1.5 times or more of the effective width of the sorting conveyor chute 1 This is a sorting baggage merging system characterized by a length of 9 times or less.

本発明の上記仕分け荷物合流システムの好ましい態様では、二つの仕分けシュートコンベヤがともに合流シュートコンベヤの一方の側面に距離を置いて合流されるか又は二つの仕分けシュートコンベヤがそれぞれ合流シュートコンベヤの両側面に対面せずに距離を置いて合流されている。   In a preferred embodiment of the above-described sorting luggage joining system of the present invention, two sorting chute conveyors are joined together at a distance from one side of the joining chute conveyor, or two sorting chute conveyors are respectively provided on both sides of the joining chute conveyor. It is merged at a distance without facing.

また、本発明の上部仕分け荷物合流システムの好ましい態様では、合流シュートコンベヤに合流される二つの仕分けシュートコンベヤの一方又は両方が合流シュートコンベヤに合流する前に他の仕分けシュートコンベヤと合流制御して合流されている。   Further, in a preferred aspect of the upper sorting luggage joining system of the present invention, before one or both of the two sorting chute conveyors joined to the joining chute conveyor join the other sorting chute conveyor, the joining sorting with the other sorting chute conveyor is controlled. Have been joined.

以下、本発明の仕分け荷物合流システムの実施態様を図面を用いて説明するが、本発明のシステムはこれらに限定されず、本発明の趣旨を逸脱しない限り、これらの実施形態を適宜組み合せたり変更したりすることができる。   Hereinafter, embodiments of the sorting and merging system of the present invention will be described with reference to the drawings. However, the system of the present invention is not limited thereto, and these embodiments may be appropriately combined or modified without departing from the spirit of the present invention. You can do it.

本発明の仕分け荷物合流システムは、仕分け機によって仕分けされた荷物を運ぶ例えば同一出荷方面行きの仕分けシュートコンベヤを合流制御なしに合流シュートコンベヤに垂れ流し合流させていること、及びそのために合流シュートコンベヤの有効幅の長さを仕分けシュートコンベヤのそれより特定の倍率で大きくしていることを特徴とする。以下、本発明の仕分け荷物合流システムの実施形態の典型例を図面とともに以下に説明する。   The sorting baggage merging system according to the present invention is configured such that a sorting chute conveyor for carrying the packages sorted by a sorting machine, for example, is dropped and joined to the merging chute conveyor without merging control, and for this reason, The length of the effective width is larger than that of the sorting chute conveyor at a specific magnification. Hereinafter, a typical example of an embodiment of the sorted luggage joining system of the present invention will be described below with reference to the drawings.

第一実施態様（図３）
図３は本発明の第一実施態様の仕分け荷物合流システムの概略的平面図を示す。図中、１，２は同じ出荷方面に仕分けされた荷物を搬送する仕分けシュートコンベヤを表し、１０はそれらのコンベヤが合流する合流シュートコンベヤを表し、矢印は荷物の搬送方向を示す。この実施形態では、仕分けシュートコンベヤが二つ存在し、一方の仕分けシュートコンベヤ１が合流制御なしに合流シュートコンベヤ１０の上流端に垂れ流し合流され、他方の仕分けシュートコンベヤ２が合流制御なしに合流シュートコンベヤ１０の左側面の位置に垂れ流し合流されている。また、合流シュートコンベヤ１０の有効幅は仕分けシュートコンベヤ１，２の有効幅の１．５倍以上１．９倍以下の長さに設定されている。 First embodiment (FIG. 3)
FIG. 3 is a schematic plan view of the sorting luggage joining system according to the first embodiment of the present invention. In the figure, 1 and 2 represent sorting chute conveyors for transporting packages sorted in the same shipping direction, 10 represents a joining chute conveyor where these conveyors merge, and arrows indicate the transporting direction of the packages. In this embodiment, there are two sorting chute conveyors, one sorting chute conveyor 1 is dropped and joined to the upstream end of the joining chute conveyor 10 without joining control, and the other sorting chute conveyor 2 is joined to the joining chute without joining control. It flows down and joins the position of the left side surface of the conveyor 10. Further, the effective width of the joining chute conveyor 10 is set to be 1.5 times or more and 1.9 times or less the effective width of the sorting chute conveyors 1 and 2.

この実施形態では、仕分けシュートコンベヤから合流シュートコンベヤへの荷物の合流制御を全く設けず、合流シュートコンベヤに垂れ流し合流しているので、システムの設備費用が安く、コストを低減することができる。また、荷物を仕分け機の下流端に流したりシュートコンベヤに滞留させる必要がないため、そのための設備が不要となり、コストを低減することができる。さらに、合流シュートコンベヤの有効幅は仕分けシュートコンベヤの有効幅の１．５倍以上の長さに設定されているので、荷物を同時に合流させても荷詰まりやそれによる荷物の損傷を回避することができる。また、合流シュートコンベヤの有効幅は仕分けシュートコンベヤの有効幅の１．９倍以下に抑制されているので、システムの設置はそれほど大きくスペースをとらなくても可能である。   In this embodiment, since the merge control of the cargo from the sorting chute conveyor to the merge chute conveyor is not provided at all, the apparatus hangs down and merges on the merge chute conveyor, so that the system equipment cost is low and the cost can be reduced. In addition, since it is not necessary to flow the cargo to the downstream end of the sorting machine or to stay on the chute conveyor, the equipment for that purpose becomes unnecessary, and the cost can be reduced. Furthermore, the effective width of the confluence chute conveyor is set to be 1.5 times longer than the effective width of the sorting chute conveyor. Can do. Further, since the effective width of the joining chute conveyor is suppressed to 1.9 times or less than the effective width of the sorting chute conveyor, the system can be installed without taking up a large space.

第二実施態様（図４）
図４は本発明の第二実施態様の仕分け荷物合流システムの概略的平面図を示す。図中、１，２は同じ出荷方面に仕分けされた荷物を搬送する仕分けシュートコンベヤを表し、１０はそれらのコンベヤが合流する合流シュートコンベヤを表し、矢印は荷物の搬送方向を示す。この実施形態では、仕分けシュートコンベヤが二つ存在し、一方の仕分けシュートコンベヤ１が合流制御なしに合流シュートコンベヤ１０の左側面の位置に垂れ流し合流され、他方の仕分けシュートコンベヤ２が合流制御なしに一方の仕分けシュートコンベヤ１の合流位置より下流の合流シュートコンベヤ１０の右側面の位置に垂れ流し合流されている。また、合流シュートコンベヤ１０の有効幅は仕分けシュートコンベヤ１，２の有効幅の１．５倍以上２．０倍未満の長さに設定されている。 Second embodiment (FIG. 4)
FIG. 4 is a schematic plan view of the sorting luggage joining system according to the second embodiment of the present invention. In the figure, 1 and 2 represent sorting chute conveyors for transporting packages sorted in the same shipping direction, 10 represents a joining chute conveyor where these conveyors merge, and arrows indicate the transporting direction of the packages. In this embodiment, there are two sorting chute conveyors, one sorting chute conveyor 1 is dropped and joined to the position of the left side surface of the joining chute conveyor 10 without joining control, and the other sorting chute conveyor 2 is not joined and controlled. One sort chute conveyor 1 hangs down and joins to the position of the right side surface of the join chute conveyor 10 downstream from the join position of the sort chute conveyor 1. Further, the effective width of the confluence chute conveyor 10 is set to be 1.5 times or more and less than 2.0 times the effective width of the sorting chute conveyors 1 and 2.

この実施形態では、第一実施形態と同様に仕分けシュートコンベヤから合流シュートコンベヤへの荷物の合流制御を全く設けず、合流シュートコンベヤに垂れ流し合流し、合流シュートコンベヤの有効幅を仕分けシュートコンベヤの有効幅の１．５倍以上１．９倍以下の長さに設定しているので、第一実施形態と同様の設備の設置コスト低減及び荷詰まりやそれによる荷物の損傷の回避などの効果が得られる。なお、この実施形態では、シュートコンベヤ１，２がそれぞれ合流シュートコンベヤ１０の左側面、右側面の位置に合流されているが、合流位置をそれぞれ互いに対面せずに距離を置いて設けることが荷物の衝突が軽減されるので好ましい。   In this embodiment, as in the first embodiment, there is no merging control of the load from the sorting chute conveyor to the merging chute conveyor. Since the length is set to 1.5 times or more and 1.9 times or less of the width, the same effects as the installation cost reduction of the equipment and avoidance of the clogging and the damage of the cargo due to the same are obtained. It is done. In this embodiment, the chute conveyors 1 and 2 are joined to the positions of the left side surface and the right side surface of the joining chute conveyor 10, respectively, but it is necessary to provide the joining positions at a distance without facing each other. This is preferable because it reduces the collision.

第三実施態様（図５）
図５は本発明の第三実施態様の仕分け荷物合流システムの概略的平面図を示す。図中、１，２，３，４は同じ出荷方面に仕分けされた荷物を搬送する仕分けシュートコンベヤを表し、１０はそれらのコンベヤが合流する合流シュートコンベヤを表し、矢印は荷物の搬送方向を示す。この実施形態は第二実施形態（図４）の変形例であり、合流シュートコンベヤ１０の左側面、右側面図のそれぞれに合流される仕分けシュートコンベヤ１，２がそれぞれ合流シュートコンベヤに合流する前に仕分けシュートコンベヤ３，４と合流されている点が新たな特徴である。この実施形態では、仕分けシュートコンベヤ１，２はいずれも合流シュートコンベヤ１０に垂れ流し合流され、仕分けシュートコンベヤ３，４は仕分けシュートコンベヤ１，２と合流制御して合流されている。合流制御は背景技術の項で述べたような従来公知の方法及び装置が採用されることができる。合流シュートコンベヤ１０の有効幅は仕分けシュートコンベヤ１，２，３，４の有効幅の１．５倍以上１．９倍以下の長さに設定されている。 Third embodiment (FIG. 5)
FIG. 5 is a schematic plan view of the sorting luggage joining system according to the third embodiment of the present invention. In the figure, 1, 2, 3, 4 represent sorting chute conveyors for transporting packages sorted in the same shipping direction, 10 represents a joining chute conveyor where these conveyors merge, and arrows indicate the direction of cargo transport . This embodiment is a modification of the second embodiment (FIG. 4), and before the sorting chute conveyors 1 and 2 joined to the left side view and the right side view of the joining chute conveyor 10 respectively join the joining chute conveyor. This is a new feature in that it is merged with the sorting chute conveyors 3 and 4. In this embodiment, the sorting chute conveyors 1 and 2 are both dropped and joined to the joining chute conveyor 10, and the sorting chute conveyors 3 and 4 are joined with the sorting chute conveyors 1 and 2 and are joined. For the merge control, a conventionally known method and apparatus as described in the background art can be adopted. The effective width of the joining chute conveyor 10 is set to be 1.5 times or more and 1.9 times or less the effective width of the sorting chute conveyors 1, 2, 3, 4.

この実施形態では、仕分けシュートコンベヤ同士の合流に合流制御を用いているが、これは仕分けシュートコンベヤが二つより多いライン数を持つとき、例えば四ラインの場合に用いる方法であり、この場合、仕分けシュートコンベヤ３，４上の荷物が満杯になり、それ以上の荷物が仕分けされると、仕分け機がダイバータロックして、荷物を仕分け機の下流端に流すことになる。一次合流された荷物は仕分けシュートコンベヤ１，２から合流シュートコンベヤへの合流には合流制御を設けず垂れ流し合流しているので、この部分はシステムの設備費用が安く、コストを低減することができる。また、合流シュートコンベヤへ直接合流する仕分けシュートコンベヤ１，２は荷物を仕分け機の下流端に流したりシュートコンベヤに滞留させる必要がないため、そのための設備が不要となりコストを低減することができる。さらに合流シュートコンベヤの有効幅は仕分けシュートコンベヤの有効幅の１．５倍以上１．９倍以下の長さに設定されているので、上述の実施形態と同様の荷詰まりやそれによる荷物の損傷の回避などの効果が得られる。   In this embodiment, the merge control is used to merge the sorting chute conveyors, but this is a method used when the sorting chute conveyor has more than two lines, for example, four lines, in this case, When the packages on the sorting chute conveyors 3 and 4 are full and more packages are sorted, the sorting machine is diverter-locked and the packages flow to the downstream end of the sorting machine. Since the merged cargo is drooping and merging without merging control for merging from the sorting chute conveyors 1 and 2 to the merging chute conveyor, this part has low system cost and can reduce costs. . Further, since the sorting chute conveyors 1 and 2 that join directly to the joining chute conveyor do not need to flow the cargo to the downstream end of the sorting machine or stay on the chute conveyor, the equipment for that purpose is not required and the cost can be reduced. Furthermore, the effective width of the confluence chute conveyor is set to be 1.5 times or more and 1.9 times or less the effective width of the sorting chute conveyor. The effect such as avoidance is obtained.

本発明の仕分け荷物合流システムでは、合流シュートコンベヤの有効幅は仕分けシュートコンベヤの有効幅の１．５倍以上１．９倍以下に設定されるが、荷物の大きさや量、使用床面積等を考慮してその範囲内で適宜増減させればよい。例えば仕分けシュートコンベヤの有効幅が８００ｍｍであるときに合流シュートコンベヤの有効幅を１２００ｍｍ、１４００ｍｍ、１５００ｍｍなどに設定することができる。   In the sorting luggage joining system of the present invention, the effective width of the joining chute conveyor is set to be 1.5 times or more and 1.9 times or less than the effective width of the sorting chute conveyor. It may be appropriately increased or decreased within the range in consideration. For example, when the effective width of the sorting chute conveyor is 800 mm, the effective width of the confluence chute conveyor can be set to 1200 mm, 1400 mm, 1500 mm, or the like.
