【産業上の利用分野】[Industrial applications]

この考案は、例えば、合成樹脂製のコンテナ、ダンボール製の箱体等の運搬用 ケースが複数段積重ねられたケース群をパレットから順次積下ろしするために用 いられるケース積下ろし装置に関する。 The present invention relates to a case unloading device used for sequentially unloading a case group in which a plurality of transport cases such as synthetic resin containers and cardboard boxes are stacked from a pallet.

【0002】[0002]

【従来の技術】[Prior Art]

上述例のような運搬用ケースが複数段積重ねられたケース群をパレットから順 次積下ろしするための積下ろし装置としては、例えば、当出願人によって既に開 発された積下ろし装置(実願平2−38725号参照)がある。この積下ろし装 置は、パレットに積重ねられた1列目〜5列目のケース群を積下ろしする位置に ケース積下ろし機を往復移動させて、同パレットに積重ねられた各列のケース群 をプッシャで1列ずつ順次積下ろしする装置である。 An example of an unloading device for sequentially unloading a case group in which a plurality of transport cases are stacked from the pallet as in the above example is, for example, an unloading device already developed by the applicant (actual application: 2-38725). This unloading device moves the case unloader back and forth to a position where the case groups in the 1st to 5th rows stacked on the pallet are loaded and unloaded, and the case groups in each row stacked on the pallet are moved. It is a device that sequentially loads and unloads one row at a time with a pusher.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかし、上述のように1列目〜5列目のケース群を積下ろしする位置にケース 積下ろし機側を往復移動させる場合、1列目のケース群を積下ろしする位置と、 5列目のケース群を積下ろしする位置との移動距離が長くなるため、5列目のケ ース群を積下ろした後、ケース積下ろし機が初期位置に復帰移動するまでは次の 積下ろし作業に移行することができず、その間、ケース群の積下ろし作業が一旦 休止されることになり、装置全体の稼働率を下げる要素を内在し、また、単位時 間当りの処理能力が低くなる要素をも内在している。 However, as described above, when the case unloading machine side is reciprocally moved to the position where the case groups of the first to fifth rows are loaded and unloaded, the position where the case group of the first row is loaded and unloaded, and the case group of the fifth row Since the moving distance from the case group unloading position becomes long, after the case group in the fifth row is unloading, the case unloading machine moves to the next unloading operation until it returns to the initial position. During that time, the unloading work of the case group is temporarily suspended, and there is an inherent factor that reduces the operating rate of the entire device, and there are also factors that reduce the processing capacity per unit time. It is inherent.

【0004】 この考案は上記問題に鑑み、パレット側を設定された移動量だけ間欠移動して 、同パレットに積重ねられたケース群を1列ずつ順次積下ろすことにより、ケー ス群の積下ろし作業が連続的に行なえ、処理能力の向上及び稼働率のアップする ことができるケース積下ろし装置の提供を目的とする。In view of the above problem, the present invention intermittently moves the pallet side by a set movement amount and sequentially unloads the case groups stacked on the pallet one by one to unload the case group. The purpose of the present invention is to provide a case unloading device that can improve the processing capacity and the operating rate continuously.

【課題を解決するための手段】[Means for Solving the Problems]

この考案は、パレットに積重ねられたケース群の積下ろし位置に、複数列積重 ねられたケース群を1列ずつ順次供給する移動量だけパレットを間欠移動するた めのパレット移動手段を設けたケース積下ろし装置であることを特徴とする。 In this invention, pallet moving means for intermittently moving the pallets by an amount of movement is provided at the unloading position of the case groups stacked on the pallet, and the case groups stacked in a plurality of rows are sequentially supplied one by one. It is a case loading / unloading device.

【作用】[Action]

この考案は、パレット移動手段を駆動して、複数列積重ねられたケース群を1 列ずつ順次供給する移動量だけパレット側を間欠移動させ、同パレットに積重ね られた複数列のケース群を積下ろし位置に配設したケース積下ろし手段に1列ず つ順次供給すると共に、同ケース積下ろし手段を駆動して、パレットに積重ねら れた複数列のケース群を1列ずつ順次積下ろしする。 In this invention, the pallet moving means is driven to intermittently move the pallet side by a moving amount for sequentially supplying the case groups stacked in a plurality of rows one by one, and the case groups in a plurality of rows stacked on the pallet are unloaded. The case unloading means arranged at the position is sequentially supplied one by one, and the case unloading means is driven to sequentially unload the plurality of rows of case groups stacked on the pallet one by one.

【考案の効果】[Effect of the device]

この考案によれば、パレット移動手段によりパレット側を設定された移動量だ け間欠移動して、パレットに積重ねられたケース群を積下ろし位置に配設したケ ース積下ろし手段により1列ずつ順次積下ろしするので、先行装置のようにケー ス積下ろし機が初期位置に復帰移動するまで作業を一旦休止する必要がなく、且 つ、同ケース積下ろし機の復帰移動に要する動作時間が短縮されるため、次のパ レットに積重ねられたケース群の積下ろし作業に即移行することができ、ケース 群の積下ろし作業が連続して行なえると共に、単位時間当りの処理能力が大幅に 向上し、装置全体の稼働率をアップすることができる。 According to this invention, the pallet moving means intermittently moves the pallet side by the set moving amount, and the case groups stacked on the pallet are arranged one row at a time by the case unloading means arranged at the unloading position. Since loading and unloading is done sequentially, it is not necessary to pause the work until the case unloading machine returns to the initial position, unlike the preceding device, and the operation time required for the return movement of the case unloading machine is shortened. Therefore, it is possible to immediately move to the unloading work of the case group stacked on the next pallet, the unloading work of the case group can be performed continuously, and the processing capacity per unit time is greatly improved. However, the operating rate of the entire device can be increased.

Stacked on one pallet P is completed, as shown in FIG. 1, the pressing plates 14 and 14 of the traveling frame 13 are opened to set the initial positions. At the same time, the moving conveyor 2 is rotationally driven in the feeding direction to convey the next pallet P on which 50 containers a are stacked to the unloading position, and the empty pallet P is stacked on the pallet stacker ( (Not shown) for stacking and collecting. Thereafter, in the same manner as described above, the moving conveyor 2 is intermittently driven in the feeding direction by one pitch for supplying the container groups A, A for one row, and the case unloading provided at the upper part of the unloading position is performed. The machine 3 is driven to successively unload the container groups A, A in the first to fifth rows stacked on the pallet P one by one. At the same time, by driving the case separator 4 arranged on the side of the unloading position, the container groups A, A for one row to be unloaded are sequentially separated from the lower side, and the separated containers a, a are transported. The sheets are sequentially transferred onto the conveyor 5 and conveyed and supplied to a sorting step (not shown).

Stacked on the pallet P to be sequentially loaded and unloaded one row at a time, so that it looks like the preceding equipment. It is not necessary to suspend the work until the case unloading machine 3 returns to the initial position, and the operation time required for the return movement of the case unloading machine 3 is shortened. The loading and unloading work of the stacked container group A can be immediately carried out, the loading and unloading work of the container group A can be continuously performed, and the processing capacity per unit time is significantly improved, and The operating rate can be increased.
