Description

This disclosure relates to transport pallets. A transport pallet is known in which the horizontal dimension of the workpiece storage section, which has an opening at the top, is variable (see Patent Document 1). This allows for increased work efficiency by widening the opening of the workpiece storage section during loading and unloading workpieces. Japanese Patent Publication No. 2011-105347 This is a diagram illustrating the transport system.This is an explanatory diagram of a transport pallet. A. First embodiment: Figure 1 is an explanatory diagram of a transport system 10 in one embodiment of the present disclosure. The transport system 10 comprises a transport pallet 100 and a robot 200. The transport system 10 uses the robot 200 to place a workpiece Wk on the transport pallet 100 and transports it. In this embodiment, the workpiece Wk has a protruding portion Pp that protrudes significantly from other parts. Figure 2 is an explanatory diagram of the transport pallet 100. The transport pallet 100 comprises a main body 110 and trays 120. In this embodiment, the transport pallet 100 comprises multiple trays 120. Note that, for ease of explanation, some trays 120 are omitted in Figure 2. Also, the trays 120 are shown floating above the main body 110. The main body 110 has a bottom surface 111, side walls 112, a first opening 113, a second opening 114, and multiple tray mounting sections 115. In this embodiment, the bottom surface 111 is substantially rectangular in shape. The workpiece Wk is placed on the bottom surface 111. The side wall portion 112 is located on the side surface extending upward from the bottom surface 111. In this embodiment, the side wall portion 112 corresponds to the surface formed by the support portions 116 that extend upward from each of the four corners of the bottom surface 111. The first opening 113 is an opening located opposite the bottom surface 111. The size of the first opening 113 is larger than the mounting surface 121 of the tray 120, which will be described later. Therefore, the tray 120 can be inserted into and removed from the first opening 113, and attached to and detached from the tray mounting section 115, which will be described later. The second opening 114 is provided in a part of the side wall 112 and is an opening that communicates with the first opening 113. The width of the second opening 114 is greater than the width of the tray 120. More specifically, the horizontal width of the second opening 114 is greater than the short side of the mounting surface 121 of the tray 120. Preferably, the horizontal width of the second opening 114 is greater than the long side of the mounting surface 121 of the tray 120. Therefore, the tray 120 can be inserted into and removed from the second opening 114, and the tray 120 can be attached to and detached from the tray mounting section 115, which will be described later. The tray mounting section 115 is the area where the tray 120 is installed. The tray mounting section 115 is provided on the side wall section 112. In this embodiment, the tray mounting section 115 is a member that abuts against and is supported by the support column section 116. The tray mounting section 115 is a U-shaped member, with each elongated portion spanning between adjacent support column sections 116 and extending in a direction perpendicular to the extension direction of the support column sections 116. Furthermore, in this embodiment, the tray mounting sections 115 are provided at predetermined intervals in the extension direction of the support column sections 116. The tray 120 is a component that can be attached to and detached from the tray mounting section 115. In this embodiment, the tray 120 is a plate-like component with a substantially rectangular shape smaller than the bottom surface 111. The tray 120 can be placed on the tray mounting section 115 without requiring support from other components. The tray 120 has a mounting surface 121 and a gripping portion 123. The mounting surface 121 is on which the workpiece Wk is placed. The mounting surface 121 is provided with a through hole 122. The through hole 122 is positioned where the protruding portion Pp of the workpiece Wk is located when the workpiece Wk is placed on the mounting surface 121. Furthermore, the through hole 122 is sized to accommodate the protruding portion Pp. The gripping portion 123 is the part that is gripped by the hand portion 210 of the robot 200. In this embodiment, the gripping portion 123 is a hole provided in the mounting surface 121, and is a different hole from the through hole 122. The robot 200 (see Figure 1) has a hand unit 210 and a control unit 220. The hand unit 210 is located at the tip of the robot 200 and is capable of grasping the workpiece Wk and the tray 120. The hand unit 210 grasps the tray 120 via the gripping unit 123. The control unit 220 consists of a computer comprising a central processing unit (CPU), RAM, and ROM. The CPU controls the ope
