DETAILED DESCRIPTION

[0021] In order to better understand the purpose, structure and function of the utility model, the specific embodiment of the utility model "a pallet truck temporary storage circulation device" is further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-Figure 5 In this embodiment, the temporary storage circulation device includes a fixed frame 100, on which a linear module 101, a workbench 102 and a temporary storage table 103 are arranged, and the workbench 102 and the temporary storage table 103 are both located directly above the linear module 101; wherein, the workbench 102 and the temporary storage table 103 are both provided with a docking track 104 in the front-to-back direction, and a plate rack vehicle 105 is carried on the docking track 104, and the plate rack vehicle 105 moves straightly forward and backward along the docking track 104. After the automated line docks with the docking track 104, the plate rack vehicle 105 is sent onto the workbench 102 / moved out of the temporary storage table 103 along the docking track 104; four top interfaces 1051 are symmetrically arranged on the front and back sides of the bottom of the plate rack vehicle 105; the linear module 101 is connected to the sliding Motor 106, a slide 107 is provided on the linear module 101, and the sliding motor 106 drives the slide 107 to slide linearly left and right on the linear module 101; four push-up cylinders 108 are symmetrically provided on the side of the slide 107, and a top joint 1081 is provided at the movable end of the push-up cylinder 108, and the push-up cylinder 108 drives the top joint 1081 to penetrate the top interface 1051, dock the plate frame car 105 and lift the plate frame car 105, so that the plate frame car 105 is suspended directly above the workbench (102); then the sliding motor 106 drives the slide 107 to drive the plate frame car 105 to move to the right to directly above the temporary storage table 103, and the push-up cylinder 108 drives the top joint 1081 to retract, and the plate frame car 105 lands smoothly on the temporary storage table 103. This device can first quickly transfer the pallet cart 105 on the workbench 102 to the temporary storage table 103 without affecting the next pallet cart 105 on the workbench 102 to go up to the table for operation. After that, the automated line slowly moves the pallet cart 105 on the temporary storage table 103 through a transfer vehicle or other transfer units and transports it to the next process / equipment. In this way, a rapid cycle of the pallet carts 105 on the workbench 102 and the temporary storage table 103 can be formed, reducing the time for the workbench 102 to stop working and wait for the pallet cart 105 to be moved out, thereby improving the automated production efficiency.

[0023] More specifically, in this embodiment, the workbench 102 and the temporary storage table 103 are located on the same horizontal plane, and the axes of the workbench 102 and the temporary storage table 103 are on the same straight line. In this way, the slide 107 transfers the pallet cart 105 from the workbench 102 to the temporary storage table 103 in a process that only moves in a straight line up, down, left and right directions, with high transfer efficiency and fast speed.

[0024] See also Figure 4 In this embodiment, the sliding motor 106 is electrically connected to the central controller (not shown), a coordinate sensor 109 is provided on the linear module 101, and the coordinate sensor 109 is electrically connected to the central controller. A coordinate positioning member 110 is provided on the slide 107, and the coordinate sensor 109 is located on the moving path of the coordinate positioning member 110; the device forms a coordinate axis in the central controller through information feedback of the coordinate sensor 109, and controls the precise position of the target movement through the central controller, and does not need to set an additional limit structure, thereby simplifying the mechanical design and reducing the mechanical manufacturing cost.

[0025] See also Figure 3 and Figure 5 In this embodiment, a positioning hole 1052 is provided at the bottom of the pallet truck 105, and a positioning cylinder 113 is provided on the workbench 102 and the temporary storage table 103, and the movable end of the positioning cylinder 113 is inserted into the positioning hole 1052 to fix the pallet truck 105.

[0026] See also Figure 3 In this embodiment, a first in-position sensor 111 electrically connected to the central controller is provided on the fixed frame 100. The first in-position sensor 111 is located behind the workbench 102 and on the path of the pallet cart 105 moving on the workbench 102 to limit the travel of the pallet cart 105 moving into position on the workbench 102, and send the in-position information of the pallet cart 105 to the central controller. The central controller controls the positioning cylinder 113 to insert the movable end into the positioning port 1052, and fixes the pallet cart 105 at the specified position of the workbench 102 for subsequent operations.

[0027] More specifically, in the present embodiment, a second in-position sensor 112 electrically connected to the central controller is further provided on the fixed frame 100. The second in-position sensor 112 is located on the right side of the temporary storage table 103 and on the path where the slide 107 drives the pallet trolley 105 to move, so as to limit the travel of the slide 107 to drive the pallet trolley 105 to move directly above the temporary storage table 103, and send the in-position information of the pallet trolley 105 to the central controller. The central controller controls the pushing cylinder 108 to retreat, so that the pallet trolley 105 drops to the specified position of the temporary storage table 103, and then the positioning cylinder 113 inserts the movable end into the positioning port 1052 to fix the pallet trolley 105 at the specified position of the temporary storage table 103 to prevent the pallet trolley 105 from slipping away; when the transfer unit of the subsequent automatic line comes over to prepare for docking and transferring the pallet trolley 105 away, the positioning cylinder 113 retreats again to release the lock.

[0028] See also Figure 1 In this embodiment, a plug-in board assembly 114 is provided on the fixed frame 100, and the plug-in board assembly 114 is located directly above the workbench 102, so that the device will integrate the plug-in board function, and the workbench 102 is specially designed for plug-in board operation, so that the operation and temporary storage cycle can be integrated on one device to improve space utilization. Of course, in other embodiments, other operation processes can be set near the workbench 102, or other operations do not need to be integrated into the fixed frame, but can be set independently, and the temporary storage circulation device only needs to quickly transfer the plate rack vehicle 105 that has completed the operation on the workbench 102 to the temporary storage table 103.
