Abstract

The disclosure discloses an object conveying system including an object conveying apparatus and a mounting table. The object conveying apparatus includes a traveling member, the vehicle member, and a transporting member. A rail which extends along a horizontal direction is disposed between the object conveying system and the mounting table. A horizontal moving mechanism of the vehicle member moves back and forth along the rail. A horizontal height of a lowest end of an outer peripheral edge of a first wheel on the horizontal moving mechanism is higher than a horizontal height of a lowest end of an outer peripheral edge of a second wheel. While the horizontal moving mechanism is moving to a direction away from the object conveying apparatus, the first wheel and the second wheel move along the rail by contacting in order.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of Taiwanese application serial no. 113108847, filed on Mar. 11, 2024. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The disclosure relates to an object conveying system, and in particular to an object conveying system that improves the tilt issue when a horizontal mechanism moves. Description of Related Art In existing object conveying systems, an object conveying apparatus moves between different stopping points to convey objects. When the object conveying apparatus stops at the stopping point, a vehicle member of the object conveying apparatus is moved to the mounting table located in the horizontal direction to perform operations of picking up and setting down objects. However, when the vehicle member approaches the mounting table, the wheels of the horizontal moving mechanism on the vehicle member (the wheels closer to the mounting table in the horizontal direction) generates impacts and vibrations when entering along the bridging portion of the rail. In order to suppress the vibration, the rail is dropped to a lower position than it originally was, causing the vehicle member to become tilted after completely entering the mounting table. SUMMARY The disclosure provides an object conveying system that can correct a tilt angle of a vehicle member and reduce the impact when entering a rail. The object conveying system of the disclosure includes an object conveying apparatus and a mounting table configured adjacent to the object conveying apparatus. The object conveying apparatus includes a traveling member, a vehicle member, and a transporting member. The traveling member is configured on a traveling rail to move along a traveling direction. The vehicle member is disposed below the traveling member and includes a horizontal moving mechanism that moves in a horizontal direction and a lifting mechanism that moves in an up-down direction. The transporting member is disposed below the lifting mechanism. A rail extending in the horizontal direction is configured between the object conveying apparatus and the mounting table. The horizontal moving mechanism moves back and forth along the rail between the object conveying apparatus and the mounting table in the horizontal direction. The horizontal moving mechanism is provided with a first wheel and a second wheel in a horizontal direction. A horizontal height of a lowest end of an outer peripheral edge of the first wheel is higher than a horizontal height of a lowest end of an outer peripheral edge of the second wheel. When the horizontal moving mechanism moves in the direction away from the object conveying apparatus in the horizontal direction, the first wheel and the second wheel move along the rail by contacting in order. In an embodiment of the disclosure, a diameter of the first wheel is the same as a diameter of the second wheel. The first wheel is disposed at a higher position relative to the second wheel in the up-down direction, and the first wheel is disposed closer to the outside relative to the second wheel in the horizontal direction. In an embodiment of the disclosure, the diameter of the first wheel is smaller than the diameter of the second wheel. The center of the first wheel is disposed at the same height as the center of the second wheel in the up-down direction, and the first wheel is disposed at a position closer to the outside relative to the second wheel in the horizontal direction. In an embodiment of the disclosure, the horizontal moving mechanism further includes a third wheel. The diameter of the third wheel is the same as the diameter of the second wheel, and the center of the third wheel is set at the same horizontal height as the center of the second wheel. The third wheel is disposed at a position closer to the side of the object conveying apparatus relative to the second wheel in the horizontal direction. When the horizontal moving mechanism moves to the mounting table, the second wheel and the third wheel are in contact with the rail. In an embodiment of the disclosure, the second wheel and the third wheel are provided with an elastic apparatus, and the elastic apparatus stretches along the up-down direction. The rail includes a tilt portion. When the horizontal moving mechanism moves to the mounting table, the tilt portion is at least located between the second wheel and the third wheel in the horizontal direction. Among the elastic apparatus, an elastic coefficient of the elastic apparatus disposed on the second wheel is different from an elastic coefficient of the elastic apparatus disposed on the third wheel. In an embodiment of the disclosure, the object conveying system further includes multiple support columns. The support columns are disposed between the object conveying apparatus and the mounting table and extend
