[0023] Example 1

[0024] like Figure 1-4As shown, an automatic tray unloading machine includes a frame 1, on which a tray conveyor 2 and an ampoule bottle conveyor 3 are installed. The tray conveyor is used to convey a tray 4 containing ampoule bottles, and the ampoule bottle conveyor is used to convey ampoule bottles. In order to better ensure the conveying effect of the ampoule bottles after unloading, tray positioning plates 5 are installed on the ampoule bottle conveyor at positions on both sides of the conveying surface corresponding to the conveying surface, and a conveying channel is formed between the two tray positioning plates. A movable baffle 6 is movably installed along the conveying direction on the ampoule bottle conveyor, and the movable baffle protects the ampoule bottles to prevent them from tipping over during the pushing process. The frame is also equipped with a tray unloading device for transferring the ampoules in the tray to the ampoule conveyor, the tray unloading device includes a tray opening mechanism 12 for opening the tray, and a push plate mechanism for pushing the ampoule out of the tray; the conveying directions of the tray conveyor and the ampoule conveyor are perpendicular to each other, and a tray limiting mechanism and a tray lifting mechanism are installed on the tray conveyor at positions corresponding to the ampoule conveyor; wherein the push plate mechanism includes a linear slide rail 7 arranged along the conveying direction of the ampoule conveyor, and a tray unloading frame 1 8 and a tray unloading frame 2 9 are movably installed side by side on the linear slide rail, a tray unloading cylinder 1 13 is installed downward on the tray unloading frame 1, and a tray unloading cylinder 2 14 is installed downward on the tray unloading frame 2, and a tray unloading push plate 10 and a tray unloading push plate 2 11 are installed at the free ends of the tray unloading cylinder 1 and the tray unloading cylinder 2, respectively.

[0025] The tray limiting mechanism includes a tray positioning rod 16 movably mounted upward, and a roller 17 that fits the side wall of the tray is mounted on the top of the tray positioning rod. In this embodiment, a plurality of tray positioning rods are arranged side by side; wherein the tray opening mechanism 12 includes a movable seat 301 movably mounted on the frame, wherein a transverse sliding block 302 is also movably mounted on the linear slide rail 7, and a linear driving mechanism three 303 for driving the transverse sliding block to move along the linear slide rail is mounted on the frame, and the movable seat is mounted on the transverse sliding block, and a lifting driving mechanism three 304 for driving the movable seat to rise and fall is mounted on the transverse sliding block; in this embodiment, the lifting driving mechanism three adopts a cylinder, and a left clamping plate and a right clamping plate are relatively movably mounted on the movable seat, and the left clamping plate 305 and the right clamping plate 306 are used to clamp the two sides of the movable plate in the tray of the ampoule bottle; a clamping driving mechanism 307 for adjusting the distance between the left clamping plate and the right clamping plate is mounted on the movable seat, and in this embodiment, the clamping driving mechanism 308 adopts two relatively arranged cylinders. The pallet lifting mechanism includes a pallet top plate 15 movably installed on the pallet conveying mechanism at a position corresponding to the position directly below the conveying surface. When the pallet top plate 15 is in a sunken state, the support surface of the pallet top plate is lower than the conveying surface of the pallet conveying mechanism. When the pallet top plate is in an ascending state, the support surface of the pallet top plate is higher than the conveying surface of the pallet conveying mechanism. In a specific implementation method, multiple pallet top plates are designed, and the lifting height of the left end of the pallet top plate is higher than the height of the right side to facilitate better unloading of the pallet.

[0026] The working principle of this device is as follows:

[0027] First, a full pallet enters the pallet conveying roller (pallet conveyor), the pallet limiting rod rises, and the pallet is conveyed to the pallet limiting rod by the pallet conveying roller (pallet conveyor) to position the pallet. The pallet lifting structure lifts the pallet, and the left end of the pallet rises to form an inclination; the pallet opening device clamps the pallet side plate and drags it to rotate to the right and fall, and the pallet side plate rotates from the left side of the pallet to the right side, and the pallet is opened. The unloading cylinder 1 and the unloading cylinder 2 move to the right, and the unloading cylinder 1 aligns with the left side of the pallet and pops out the push plate to close the pallet to prevent the bottle from falling. The push rod of the unloading cylinder 1 continues to pop out and falls together with the pallet lifting structure, so that the pallet falls on the roller. The unloading cylinder 2 moves to the right to the rightmost side of the pallet, and the push plate pops out to push the pallet to the left to the pallet positioning structure. The unloading cylinder 1 follows the movement on the left side of the pallet to prevent the bottle from falling. The unloading cylinder 2 retracts the push plate and moves to the left to align with the inner wall of the right side of the pallet, and then pops out the push plate, pushing the ampoule bottle to the left, and the unloading cylinder 1 follows the movement in front of the ampoule bottle to prevent the bottle from falling. The unloading cylinder 1 is aligned with the moving baffle of the ampoule bottle, the push rod of the unloading cylinder 1 is retracted and reset, the moving baffle of the ampoule bottle rises, moves to the right to align with the unloading cylinder 2 and then drops. The moving baffle of the ampoule bottle moves slowly behind the ampoule bottle to prevent the bottle from falling. At this time, the unloading is completed. The unloading cylinder 2 pushes the empty pallet to the right to move onto the roller until it is reset. The push rod of the unloading cylinder 2 is retracted and reset, and the pallet opening device is reset. The pallet limit rod drops. The pallet conveying roller sends the empty pallet after the bottle is unloaded out of the unloading machine, and the automatic unloading machine is completed.
