The system further comprises a control system for controlling the transport vehicle and the third conveyor, The transport vehicle is equipped with a restricting unit that restricts the movement of the articles supported by the plurality of supports toward the downstream side in the transport direction when in the receiving and traveling state, The article transport equipment according to claim 2, wherein the control system, when transferring the article from the third conveyor to the transport vehicle, sets the speed at which the article is transported by the third conveyor to be greater than the travel speed of the transport vehicle in the receiving travel state.
The article conveying equipment according to claim 3, wherein the plurality of support members are inclined downwards as they move downstream in the conveying direction during the receiving and traveling state.
The first conveyor comprises an upstream conveyor section and a downstream conveyor section located downstream of the upstream conveyor section in the conveying direction, The article conveying equipment according to any one of claims 1 to 4, wherein the inclination angle of the upstream conveyor section is smaller than the inclination angle of the downstream conveyor section.
The article is provided with a pair of guide members that guide the position of the article in the width direction, The article conveying equipment according to any one of claims 1 to 4, wherein the pair of guide members are arranged in the portion of the first conveyor above the contact surface of the support, or in the conveying direction region where the second conveyor is arranged, such that the spacing between them in the width direction gradually narrows as they move downstream in the conveying direction.

Description

This invention relates to an article conveying system. For example, Japanese Utility Model Publication No. 48-086575 (Patent Document 1) discloses technology related to article conveying equipment. In the following description of the background art, the reference numerals in parentheses refer to Patent Document 1. The article transport equipment described in Patent Document 1 comprises a transport vehicle (cart 2) for carrying and transporting articles (cargo 6), a first conveyor (conveyors 5, 12) for transporting articles received from the transport vehicle, and a second conveyor (conveyor 10) adjacent to the first conveyor on the downstream side in the article transport direction. The transport vehicle travels with articles loaded on its body. The first conveyor is inclined downwards as it moves upstream in the article transport direction. The first conveyor receives articles from the transport vehicle and transports them toward the second conveyor.

The following describes an embodiment of the goods handling equipment based on the drawings. As shown in Figures 1 and 2, the article conveying equipment 1 comprises a first conveyor 11 and a second conveyor 12 that convey articles W along the conveying direction X, and a transport vehicle 2 equipped with a support part 3 that supports articles W from below. In this embodiment, articles W supported by the support part 3 of the transport vehicle 2 are handed over to the first conveyor 11, and then conveyed from the first conveyor 11 to the second conveyor 12. In the following description, the upstream side of the conveying direction X will be referred to as the upstream side X1, the opposite side as the downstream side X2, and the direction perpendicular to the conveying direction X in a vertical view along the vertical direction will be referred to as the width direction Y. The first conveyor 11 is positioned on the upstream side X1 of the conveying direction relative to the second conveyor 12. In this embodiment, the first conveyor 11 is positioned adjacent to the second conveyor 12. The article conveying equipment 1 also further comprises a third conveyor 9 that conveys articles W along the conveying direction X. The third conveyor 9 is positioned downstream X2 in the transport direction relative to the second conveyor 12. In this embodiment, the article W, which is transferred from the first conveyor 11 and moves along the transport direction X on the second conveyor 12, is transferred from the second conveyor 12 to the third conveyor 9. These conveyors are arranged in the order described above: first conveyor 11, second conveyor 12, and third conveyor 9, from the upstream side X1 in the transport direction to the downstream side X2 in the transport direction. In this example, as shown in Figures 1 and 2, the travel path of the transport vehicle 2 that travels to transfer the article W between the first conveyor 11 and the third conveyor 9 is set along the transport direction X. The article transport equipment 1 is equipped with multiple transport vehicles 2. The second conveyor 12 is arranged along a horizontal plane. In this embodiment, the second conveyor 12 is arranged along a horizontal plane and along the transport direction X. Here, "arranged along a horizontal plane" includes not only being arranged parallel to the horizontal plane, but also being arranged at a slight inclination with respect to the horizontal plane (for example, a plane with an inclination angle of about 1 to 2 degrees). On the second conveyor 12, for example, work may be performed on the goods W being transported, and the goods W may be transferred to and from other transport devices (stacker cranes, etc.). Examples of work on the goods W being transported include picking work on the goods W if the goods W are containers (carton containers, collapsible containers, etc.). Furthermore, an example of the transfer of goods W between other transport devices as described above is an automated warehouse where other transport devices further transfer goods
