AI Technical Summary
In the existing technology, manual transportation during the ammunition primer loading process is inefficient and cannot meet the cycle time requirements of automated production lines, resulting in excessive downtime at the loading station while waiting for materials, which seriously affects production efficiency.
A fully automatic bottom fire pallet circulating conveying mechanism was designed, including a feeding pallet lifting mechanism, a discharging pallet lifting mechanism, a pallet conveying mechanism, and a pallet transfer mechanism. The automated conveying and transfer of pallets is achieved through an electric drive module and a cylinder, ensuring continuous operation.
It achieves continuous material supply at the primer filling station with zero downtime, improves work efficiency by 40%, and achieves pallet positioning accuracy of ±0.5mm with a conveying cycle time of ≤5 seconds/pallet.

Abstract
Claims
1. A fully automatic primer tray circulation conveyor mechanism characterized by, include: The underfire feeding and filling bracket, the feeding pallet lifting mechanism located on one side of the underfire feeding and filling bracket, the unloading pallet lifting mechanism located on the other side of the underfire feeding and filling bracket, the pallet conveying mechanism installed on the underfire feeding and filling bracket and connecting the feeding pallet lifting mechanism and the unloading pallet lifting mechanism, and the pallet transfer mechanism installed on the underfire feeding and filling bracket and docking with the unloading pallet lifting mechanism. The feeding pallet lifting mechanism is used to receive the pallet frame transported by the transfer vehicle and lift the bottom fire support pallet in the pallet frame to the material picking position of the unloading pallet lifting mechanism. The pallet frame contains multiple layers of bottom fire support pallets placed from top to bottom. The unloading pallet lifting mechanism is used to receive the bottom fire bearing pallet from the unloading position of the pallet conveying mechanism and lift the bottom fire bearing pallet to the pallet transfer mechanism. The pallet conveying mechanism is used to sequentially transport the bottom fire bearing pallet at the loading position directly above the feeding pallet lifting mechanism to the picking position and the unloading position in the horizontal direction. The picking position is located directly below the bottom fire filling process position, and the unloading position is located directly above the unloading pallet lifting mechanism. The pallet transfer mechanism is used to transport the pallet rack to the manual retrieval station.
2. A full automatic primer tray circulation conveyor mechanism according to claim 1, characterized in that, The feeding pallet lifting mechanism includes: a receiving tray, a feeding pallet lifting module installed below the receiving tray, and a feeding pallet drive motor for driving the feeding pallet lifting module. The upper end of the receiving tray has two limiting baffles corresponding to the width of the pallet frame. A protruding positioning pin and a clearance opening are provided on the upper end of the receiving tray between the two limiting baffles. Positioning grooves are provided on both sides of the bottom of the pallet frame corresponding to the position of the protruding positioning pin. The clearance opening is used for the feeding pallet lifting module to pass through the receiving tray and lift the pre-fired pallet inside the pallet frame. The transfer vehicle transports the pallet frame with pre-fired material to the receiving tray and engages the positioning grooves of the pallet frame with the protruding positioning pins. The feeding pallet drive motor, through the feeding pallet lifting module, vertically lifts the pre-fired pallet inside the pallet frame to the loading position of the pallet conveying mechanism.
3. A full automatic primer tray circulating conveyor mechanism according to claim 1, characterized in that, The pallet conveying mechanism includes: two horizontal pushing cylinders symmetrically arranged on the top of the primer feeding and filling bracket in the horizontal direction, and a pusher frame installed on the push rods of the two horizontal pushing cylinders. The pusher frame is used to drive the primer holding pallet at the feeding position to be conveyed in the horizontal direction to the picking position. The primer holding pallet at the feeding position pushes the primer holding pallet at the picking position after the primer has been removed to the unloading position.
4. A full automatic primer tray circulation conveyor mechanism according to claim 3, characterized in that, The pusher frame is equipped with a spring locking tongue seat, and the locking tongue on the spring locking tongue seat clamps the side wall of the bottom fire support tray under the action of the spring.
5. A full automatic primer tray circulation conveyor mechanism according to claim 1, characterized in that, The unloading pallet lifting mechanism includes a pallet lifting module and a pallet driving motor. The pallet driving motor receives the bottom fire support pallet at the unloading position through the pallet frame on the pallet lifting module. When the pallet frame on the pallet lifting module is full of bottom fire support pallets, the pallet lifting module transports the pallet frame full of bottom fire support pallets to the pallet transfer mechanism.
6. A full automatic primer tray circulation conveyor mechanism according to claim 1, characterized in that, The pallet transfer mechanism includes: a guide rail frame installed horizontally on the primer loading and filling bracket, and a slider frame slidably connected to the guide rail frame. The bottom slider of the slider frame is slidably connected to the tray discharge guide rail of the guide rail frame. A tray discharge plate is installed on the top frame of the slider frame. The guide rail frame is located directly below the unloading position. The tray discharge plate on the slider frame receives the pallet frame filled with empty primer loading pallets conveyed by the tray discharge lifting module. A manual pull handle is installed on the side of the slider frame. When manually pulled, the manual pull handle moves the pallet frame horizontally from directly below the unloading position to the manual removal station. After the pallet frame filled with empty primer loading pallets is removed, the empty pallet frame is installed on the tray discharge plate, and the manual pull handle is pushed to push the empty pallet frame to the tray discharge lifting module. The tray discharge lifting module drives the empty pallet frame to repeatedly receive primer loading pallets from the unloading position.
7. A full automatic primer tray circulating conveyor mechanism according to claim 1, characterized in that, Both the inlet lifting module and the outlet lifting module are electrically driven modules. Each of the inlet lifting module and the outlet lifting module includes: a vertically arranged guide rail, a slider mounted on the guide rail and reciprocating on the guide rail, and a screw drive assembly, a gear and rack drive assembly, or a synchronous belt drive assembly for driving the slider. A pusher seat is installed on the slider. The pusher seat contacts the bottom of the pallet frame and lifts the pallet frame vertically under the drive of the slider.
