【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.

【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。同装置は、パレットに 積重ねられた複数列のケース群と対応する位置に装置本体を走行移動させ、同装 置本体の積出し側に設けたケース積出し機を駆動して、パレットに積重ねられた 複数列のケース群をプッシャで1列ずつ順次積下ろしすると共に、同装置本体の 分離側に設けたケース分離機を駆動して、パレットから積下ろされた1列分のケ ース群を下段側から順次分離し、同ケース群の下段側から分離した運搬用ケース を選別工程(図示省略)に搬送する装置である。 As an example of an unloading device for sequentially unloading a case group in which a plurality of carrying cases are stacked from one another from a pallet, there is, for example, an unloading device already developed by the applicant (Japanese Patent Application No. 2-38725). No.)). The equipment moves the equipment body to a position corresponding to the multiple rows of case groups stacked on the pallet, and drives the case unloader installed on the unloading side of the equipment main body to drive the multiple objects stacked on the pallet. The case groups in a row are sequentially loaded and unloaded one row at a time using a pusher, and the case separator installed on the separation side of the main unit of the equipment is driven to set the case group for one row unloaded from the pallet to the lower side. It is a device that sequentially separates from the lower case side of the same case group and conveys the transportation case to the sorting step (not shown).

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

しかし、上述のようにケース積出し機によりパレットから積下ろされる複数列 のケース群を一つのケース分離機で順次分離する場合、ケース積出し機により1 列分のケース群を積下ろしする処理時間よりも、ケース分離機により1列分のケ ース群を分離する処理時間の方が長くかかり、しかも、分離に要する処理時間は 積重ねられた運搬用ケースの分離段数が多くなる程長くなるので、先に積下ろさ れたケース群がケース分離機上に存在している間は、次列のケース群をケース分 離機上に供給することができず、1列分の分離作業が終了するまでケース積出し 機によるケース群の積下ろし作業を一旦休止しなければならない。且つ、ケース 分離機の処理速度を速くしても、一つのケース分離機によって分離できるケース 群の分離段数及び分離速度には限界があるため、ケース分離機の処理時間をケー ス積出し機の処理時間よりも短縮することはできず、現状の積下ろし装置では処 理能力の向上及び稼働率のアップを図ることが困難である。 However, as described above, when a plurality of rows of case groups that are unloaded from the pallet by the case unloader are sequentially separated by one case separator, the processing time required to unload one row of case groups by the case unloader is less than the processing time. However, the processing time for separating case groups for one row by the case separator is longer, and the processing time required for separation is longer as the number of separation stages in the stacked transport cases is longer. While the case group that was unloaded on the case exists on the case separator, the case group in the next row cannot be supplied to the case separator, and the case until the separation work for one row is completed. The unloading work of the case group by the unloading machine must be temporarily stopped. Moreover, even if the processing speed of the case separator is increased, the number of separation stages and the separation speed of the case group that can be separated by one case separator are limited, so the processing time of the case separator is reduced. The time cannot be shortened, and it is difficult to improve the processing capacity and the operating rate with the current unloading equipment.

【0004】 この考案は上記問題に鑑み、ケース積出し手段により積下ろされるケース群を 複数のケース分離手段に対して振分け供給することにより、ケース群の積下ろし 作業及び分離作業が連続して行なえ、処理能力の向上及び稼働率のアップを図る 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 problems, the present invention distributes and supplies the case groups that are unloaded by the case unloading means to a plurality of case separating means, so that the unloading operation and the separating operation of the case groups can be performed continuously. The purpose is to provide a case unloading device that can improve processing capacity and operating rate.

【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複数列のケース群をケース積出し手段で 1列ずつ順次積下ろし、該ケース群をケース分離手段で上下段に1段ずつ順次分 離するケース積下ろし装置であって、上記ケース積出し手段の積下ろし側に、該 ケース積出し手段の積下ろし方向と直交してケース分離手段を複数配設すると共 に、前記ケース積出し手段により積下ろされるケース群と対応する位置に複数の ケース分離手段を相対移動するケース振分け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。 This invention is a case unloading device in which a plurality of rows of case groups stacked on a pallet are sequentially unloaded one by one by a case unloading means, and the case groups are sequentially separated one by one in the upper and lower tiers by the case separating means. Then, a plurality of case separating means are arranged on the unloading side of the case unloading means orthogonal to the unloading direction of the case unloading means, and at a position corresponding to the case group unloading by the case unloading means. It is a case loading / unloading device provided with case sorting means for relatively moving a plurality of case separating means.

【作用】[Action]

この考案は、ケース積出し手段を駆動して、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と共に、ケース振分け手段を駆動して、ケ ース積出し手段により積下ろされるケース群と対応する位置に複数のケース分離 手段を相対移動させ、ケース積出し手段により積下ろされるケース群を複数のケ ース分離手段に対して振分け供給し、これらケース分離手段を夫々駆動して、複 数段積重ねられたケース群を上下段に1段ずつ順次分離するので、ケース群の積 下ろし作業及び分離作業が連続して行なえる。 This invention drives a case unloading means to sequentially unload a plurality of rows of case groups stacked on a pallet one by one, and drives a case allocating means to unload the case by the case unloading means. A plurality of case separating means are relatively moved to a position corresponding to the group, and the case groups that are unloaded by the case unloading means are distributed and supplied to the plurality of case separating means, and these case separating means are driven respectively, Since the case groups stacked in multiple stages are sequentially separated one by one in the upper and lower stages, the loading and unloading work of the case groups and the separating work can be performed continuously.

【考案の効果】[Effect of the device]

この考案によれば、ケース積出し手段により積下ろされるケース群を複数のケ ース分離手段に対して振分け供給するので、一方のケース分離手段側に振分け供 給されたケース群の分離に要する時間を利用して、他方のケース分離手段側に次 列のケース群を振分け供給することができ、先行装置のように1列分の分離作業 が終了するまでケース群の積下ろし作業を一旦休止する必要がなく、次列のケー ス群を積下ろしする作業に即移行することができるため、パレットに複数列積重 ねられたケース群の積下ろし作業及び分離作業が連続して行なえ、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, since the case groups unloaded by the case unloading means are distributed and supplied to the plurality of case separating means, the time required for separating the case groups distributed and supplied to one case separating means side. The case group in the next row can be distributed and supplied to the other case separating means side by using, and the unloading operation of the case group is temporarily stopped until the separation operation for one row is completed like the preceding device. There is no need to do so, and it is possible to immediately move to the case of unloading the case group in the next row.Therefore, unloading work and separation work of case groups stacked in multiple rows on a pallet can be performed continuously, and unit time The processing capacity per hit is greatly improved, and the operating rate of the entire device can be increased.
