JP 2011-11883 A JP-A-6-313373

  By the way, in a stacker crane type automatic warehouse like patent document 1, although many storage shelves can be taken, since one stacker crane moves horizontally and perpendicularly and conveys a conveyance thing, it is equivalent to that. There was a problem that it took time to enter and exit.

  Further, in the method of combining the transport carriage and the lifting lift as in Patent Document 2, in the case of an automatic warehouse with a long length direction, since the length of one lane becomes longer, the travel time of the transport carriage becomes longer, and entry / exit is performed. There is a problem that the time involved in

  Furthermore, in the automatic warehouse, at the entrance / exit area arranged at one end in the length direction, the distance from the entrance / exit area to the storage location of the transported goods is long, and it takes a long time to transport the storage place from the storage area to the outside of the warehouse. There was a problem that it took.

  Also, in automated warehouses where transported goods are loaded and stored on transport media such as pallets and containers, transport pallets and other transport media that have been emptied after delivery are transported and stored. A process of taking out and transporting the medium is necessary, and the entry / exit time is increased, or a dedicated system is provided, which increases the cost.

  This invention is an automatic warehouse that solves the problem that, in an automatic warehouse, the lane on which the transport carriage travels becomes longer as the number of articles to be transported becomes enormous, the travel time of the transport carriage increases, and time is required for loading and unloading. Provide a warehouse.

  In order to solve the above-mentioned problems, the present invention arranges storage shelves side by side on both sides or one side of a luggage compartment conveyance path configured by arranging a single row or a plurality of rows in parallel, and the storage shelf group is arranged in a luggage compartment conveyance path. In an automatic warehouse, which is divided into a plurality of compartments in the direction of, and placed on a single-story floor or upper and lower multi-story floors, and each of the compartments is provided with a luggage compartment transport carriage movable along the luggage compartment transport path. In addition, an entry / exit conveyance path is arranged in a direction orthogonal to the luggage compartment conveyance path between the respective compartments and at an end facing the outside as necessary, and each entry / exit conveyance path is provided with an external portion as necessary. The transfer device for loading / unloading the transported goods between them is adjacent, and the loading / unloading transport cart is movably arranged along the loading / unloading transport path. And the loading / unloading transportation carts stop adjacent in the orthogonal direction, An automatic warehouse is characterized in that to allow horizontal conveyance by transfer between the goods compartment conveyance carriage and entry and leaving the platform car.

  The invention of claim 2 is the automatic warehouse according to claim 1, wherein when the transported goods are horizontally transported across the divided sections, the transported goods mounted by relaying the loading / unloading transport cart disposed between the sections are arranged. It is an automatic warehouse characterized in that it is transported horizontally by a relay type by being transferred between a luggage compartment transport cart and an entry / exit transport cart.

  In the automatic warehouse according to claim 1, in the automatic warehouse according to claim 1, at least one of the incoming / outgoing transport paths is left, the other incoming / outgoing transport paths are removed, and the transported goods are horizontally transported across the divided sections. It is an automatic warehouse characterized in that it is transported horizontally by a relay type by relaying a loading / unloading transport cart or directly transferring between cargo storage carts.

  A fourth aspect of the present invention is the automatic warehouse according to any one of the first to third aspects of the present invention, which is an automatic warehouse of a type in which a conveyed product is transported in a state of being mounted on a transport medium, and is a luggage storage carriage. It is characterized by having a structure in which a plurality of transport media can be mounted on either or both of the transporting carts and the loading / unloading transport carts, and the transport media loaded with the transported materials and the empty transport media are exchanged when transferring the transported materials between the carts. It is an automatic warehouse.

  A fifth aspect of the present invention is a cart-type transport device configured by a horizontal transport system using the luggage compartment transport cart and the loading / unloading transport cart described in the first to fourth aspects.

  The present invention divides a storage shelf group having a long traveling direction of a dolly in an automatic warehouse into a plurality of sections, and in each of the divided sections, a luggage compartment transport cart that travels on a luggage compartment transportation path is provided, and between each section And, if necessary, the loading / unloading conveyance path is also arranged at the end of the loading / unloading conveyance path in the direction orthogonal to the loading / unloading conveyance path, and the loading / unloading conveyance carriage is arranged on this loading / unloading conveyance path. Then, the loading / unloading transport cart is stopped adjacently in the orthogonal direction, and the loaded transported material is transferred between the carts, so that the transport to the transfer device installed adjacent to the loading / unloading transport path becomes possible.

  The entry / exit conveyance path in the present invention is provided between the divided sections and at both ends (facing the outside) of the entire luggage compartment conveyance path at right angles to the luggage compartment conveyance path. There is no need to provide an exit / conveyance path, and the installation may be omitted at one end or both sides. In that case, an entrance / exit transport path between sections can be substituted.

  The transfer device according to the present invention refers to a device that delivers and receives a material to / from a loading / unloading carriage on the loading / unloading conveyance path at a portion where the conveyed material is loaded into or unloaded from the outside. If the floor is composed of multiple floors or has a level difference from the ground, a loading / unloading lift with a lifting / lowering function is suitable, and the loading / unloading lift can transport the goods to the loading / unloading carriage on each floor. When the warehouse is installed on the ground floor with a single floor, it does not require a loading / unloading lift and simply becomes a loading / unloading place. As the transfer device, various other devices such as a conveyor, a lift and a crane can be considered.

  As described above, according to the present invention, the longitudinal direction of the luggage compartment conveyance path is divided into sections, and the loading / unloading conveyance path and the loading / unloading lift are arranged in the orthogonal direction at each section end, so that one lane The problem that the distance from the loading / unloading place to the storage place of the transported goods is long and it takes a long time to transport can be solved.

  In addition, when it is necessary to enter / exit with a storage lift far away from the storage shelf section in the automatic warehouse, the luggage compartment transport carts in each section are used to store the input / output transport carts arranged in the orthogonal direction between the sections. Each section is transported horizontally by a relay type by transferring the transported goods mounted by relay between the carriages.

  For example, in an automatic warehouse composed of 1 to 3 wards, when warehousing from the 1 ward entry / exit lift to the 3 ward storage shelves, the 1 ward entry / exit lift Carrying with the loading / unloading transportation cart in the 1st district → Carrying / unloading transportation cart in the 2nd district → Carrying / departing transportation cart in the 2nd district → Entrance / exit transporting cart in the 3rd district → Relay to the cargo transporting cart in the 3rd district The transported goods are transferred between the carriages and transported to the designated storage rack.

  In the case of continuous warehousing, in the conventional method with three sections as one lane, one luggage compartment transport cart runs from the first section to the third section and transports and stores the luggage to the storage shelf in the third section. The next warehousing operation cannot be performed while the baggage compartment transport carriage reciprocates and the loaded cargo is transferred and stored.

  In the present invention, the luggage storage carriage in each compartment transfers the loaded luggage to the luggage compartment transportation carriage in the adjacent compartment via the entry / exit delivery carriage at the end of the compartment, so that after the transfer, the next receipt luggage receipt is received. For this reason, it is possible to move and move in, so that the tact time (interval time for continuous loading and unloading) when continuously loading or unloading can be shortened.

  In addition, in an automatic warehouse where there is no need to place a transfer device such as a loading / unloading lift in each section, it is possible to use a loading / unloading conveyance path where the transfer apparatus is not adjacent, or to remove the loading / unloading conveyance path between each section. The tact time can be reduced by relaying the transport cart on the incoming / outgoing transport path, or by horizontally transporting the loaded goods between the carts by stopping the adjoining carriages in the luggage compartments of each section and moving them between the carts. Can be shortened.

  In an automated warehouse that uses a transport medium such as a pallet or container for the stored goods, the goods to be transferred between the trucks can be transferred by using a double deck system for either the luggage compartment transport cart and the entry / exit transport cart. The exchange time of the pallet (conveyance medium) and the empty pallet (conveyance medium) can be exchanged to reduce the collection time of the empty pallet (conveyance medium) and the dedicated collection and storage equipment. It is possible to solve the problem of increasing the storage time for transporting and storing the transport medium and transporting the transport medium such as an empty pallet at the time of storage.

Although it was an automatic warehouse that issues goods to the first floor shipping area and transports them to the truck berth for shipping, as another embodiment, it is a multi-tiered automatic warehouse. It is also possible to store the goods and take out from the entry / exit area on the first floor, and it is possible to further rationalize.

In this embodiment, the transported object is mounted on a pallet and transported and stored. However, as another embodiment, a three-dimensional transport medium such as a container can be used.
In addition, without using transport media such as pallets and containers, the loading / unloading lifts and loading / unloading transport carts, luggage storage carts, and pallet mounting parts of storage shelves should be configured using transport elements such as slat conveyors. It is also possible to directly handle the transported object without using a transport medium such as a pallet or a container.

  FIG. 12 is a simulation of the work process at the time of warehousing. The upper figure (A) shows the continuous warehousing process by the transfer transportation according to the present invention, and the lower figure (B) shows the continuous warehousing process by the reciprocating conveyance of the single carriage which is the conventional method. The working time is compared under the same conditions.

  The simulation conditions are as follows: transfer distance: 50 × 3 sections = 150 m, luggage room transfer carriage traveling speed: 1.5 m / sec, transfer time from the entry / exit transfer carriage: 10 sec, transfer time between the luggage compartment transfer carriages: 20 sec, entry Time: 10 sec.

  In the conventional reciprocating conveyance by one carriage, the time required for transit can be omitted, so that the first warehousing time is short, but the second and subsequent warehousing times are long due to a loss of waiting time for the carriage.

  On the other hand, in the transfer transportation of the transport cart according to the present invention, the first warehousing time is long because it includes the time of two transits, but each transport cart transports the transported material at the connecting section. If it is transferred to the carriage, the next warehousing operation is possible, so that the process loss is small and the warehousing time after the second can be shortened.

  That is, in the present invention of FIG. 12 (A), the luggage compartment carriage (I) in the first section to which the incoming goods are transferred from the loading / unloading carriage is transported 50m in the first section and is separated at the section boundary. If the warehousing goods are transferred to and returned from the two compartment luggage carrier carriage (II), the second warehousing goods can be transferred from the warehousing carriage truck, and the loading / unloading carriage truck is waiting to be transferred. The time is 87 seconds (a).

  Luggage compartment transport cart (II) and luggage compartment transport cart (III) are the same as above. Each process cycle time can be shortened by shortening.

  On the other hand, in the conventional method shown in FIG. 12B, the luggage storage carriage to which the incoming goods are transferred from the incoming / outgoing transport carriage transports a distance of 150 m for three sections and enters the incoming storage goods into the incoming storage shelf. The second incoming / outgoing goods cannot be transferred from the incoming / outgoing transport cart until it returns, and the transfer waiting time of the incoming / outgoing transport cart is 210 seconds (b).

  From the simulation results of FIG. 12, in the method of dividing the conveyance path according to the present invention, the second and subsequent warehousing times are executed at an interval of 97 seconds (c). The warehousing time is executed at intervals of 220 seconds (d), and the effect of the present invention is shortened by 123 seconds (55%).
