The prior art lifting device has a lower station and an upper station, and it can be said that a single elevator or the like reciprocates between the lower station and the upper station. For this reason, the prior art lifting device has the disadvantage of poor transport efficiency.
That is, in the prior art lifting device, when transferring the transported object from the lower conveyor to the upper conveyor, the transported object is carried from the lower conveyor to the lower station of the lifting apparatus. Then, the lift is moved up to move the conveyed product to the upper station. Thereafter, the conveyed product is carried out from the upper station to the upper conveyor.

  For this reason, when the lifting platform or the like is in a station on the upper side of the lifting device, the lower station is not provided with a lifting platform or the like, and a conveyed product cannot be carried into the lifting device. Therefore, in the prior art lifting device, in order to wait for the arrival of the lifting platform or the like, it is necessary to wait for the conveyed object in front of the lifting device.

  Then, this invention makes it a subject to provide the raising / lowering apparatus with high conveyance efficiency in view of the problem of the prior art mentioned above. Moreover, this invention makes it a subject to provide the sorting apparatus which can sort a conveyed product efficiently.

  Aspects for solving the above-described problems include an upper station, a lower station, a plurality of lifting platforms that move up and down between the upper station and the lower station, and a lateral direction in the upper station. One or a plurality of upper side horizontal mounting tables that move to the lower side station, and one or more lower side horizontal mounting tables that move in the horizontal direction in the lower station, and any one of the elevating mounting tables is the upper station When the upper side horizontal mounting table is adjacent to the lifting / lowering table, the upper side horizontal mounting table and the lifting / lowering table form a series of transport paths, and the lifting / lowering table leaves the upper station. And the upper side horizontal mounting table moves to the position where the lifting platform is located, and when any lifting platform is in the lower station, the lower side mounting table is adjacent to the lifting platform. The lower side horizontal mounting table forms a series of transport paths with the lower side mounting table and the lower level mounting table leaves the lower side station and the lower side horizontal mounting table has the lifting table. A lifting device characterized by moving to a position.

The lifting device of this aspect has a plurality of lifting platforms. Therefore, when one lifting platform is in the upper station, the other lifting platform can be retained on the lower station. Similarly, when one lifting platform is at the lower station, the other lifting platform can be retained at the upper station. Therefore, for example, while the conveyed product on the upper station is being discharged from the lifting device, the conveyed product can be carried onto the mounting table of the lower station.
Further, in the lifting device of this aspect, the upper side station has the upper side horizontal mounting table, and the lower side station has the lower side horizontal mounting table.
When the lifting platform is in the upper station, the upper lateral platform is located adjacent to the lifting platform and the upper lateral platform and the lifting platform form a series of transport paths. Therefore, when the lifting / lowering table is in the upper station, the conveyed product can be carried into the lifting / lowering table, or the conveyed product can be unloaded from the lifting / lowering table.
Similarly, even when the lifting / lowering table is at the lower station, it is possible to carry a conveyed product into / from the lifting / lowering table or unload the conveyed product from the lifting / lowering table.
Further, when the lifting platform is moved away from the upper station, the upper horizontal mounting table moves to the position where the lifting platform is located, and there is an empty space at another position of the upper station. Can be placed in that empty space.
The same applies to the lower station.

  According to this aspect, it is possible to smoothly carry in the conveyed product to the lifting platform and to carry the conveyed product from the lifting platform.

  It is desirable that the plurality of lifting platforms are connected by linear members, and when one moves upward, the other moves downward, and when one moves downward, the other moves upward.

  According to this aspect, since the lifting platform is moved up and down synchronously, there is little waste of time.

The lower side station can carry in and / or carry out the transported object from one side surface and / or both side surfaces of the lifting device, and the upper station is one side surface and / or both side surfaces of the lifting device. It is desirable that the conveyed product can be carried in and / or out from the side, and the conveyed product can be conveyed by at least one of the following routes.
(1) A stepwise linear ascending route that is a lower-side station that carries a conveyed product from one side of the lifting device and that is an upper-side station that carries the conveyed product to the traveling direction side of the conveyed product. (2) A lower-side straight traveling route that is a lower-side station that carries a conveyed product from one side of the lifting device and unloads the conveyed product from the other side of the lower-side station.

(4) A stepwise linear descent route that is an upper station that carries a conveyed product from one side of the lifting device and that is a lower station that carries the conveyed product to the traveling direction side of the conveyed product. (5) An upper-side straight traveling route that is an upper-side station that carries a conveyed product from one side of the lifting device and unloads the conveyed product from the other side of the upper-side station.
(6) A stepped U-turn descent route that is an upper station that carries a conveyed product from one side of the lifting device and that is a lower station that carries the conveyed product in a direction opposite to the traveling direction side of the conveyed product.

  It may have a plurality of upper stations.

  In the aspect related to the sorting apparatus, there are a plurality of stations at different heights, and each station has a plurality of areas in which mounting tables are arranged, and a plurality of lifts that move between the plurality of stations having different heights. An area that has a mounting table and a horizontal mounting table that moves horizontally in each station, and when any of the lifting platforms is in an area within any station, the area where the horizontal mounting table of that station is adjacent In this case, a series of conveying paths are formed by the horizontal mounting table and the lifting table, and when the lifting table leaves the station, the horizontal mounting table moves to a position where the lifting table is located. Thus, the sorting apparatus is such that the area where the horizontal mounting table is placed becomes empty and the other lifting and lowering table is placed in the empty area.

  The lifting device and the sorting device of the present invention have stations on the upper and lower sides, and can transport the transported material to the lifting platform of the other station while discharging the transported product from the lifting platform at one station. .
