[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device for automatic pallet unpacking and intelligent pallet quantity identification uses a telescopic cylinder to extend and push the forks through a push plate to move and insert them into the SP2 pallet under the limiting of the horizontal slide block and slide rail. After the forks are inserted, the second drive motor starts. The working second drive motor drives the second transmission rod to rotate through the reducer, transmission toothed belt and driven gear. Since the drive gears at both ends of the rotating second transmission rod are connected to the lifting toothed belt and drive it to rotate, the connecting arm connected to the lifting toothed belt is pulled upward by the movement of the lifting toothed belt. The upward-moving connecting arm pulls the support plate and forks to lift the position to the SP3 position. At this time, the horizontal conveyor belt runs and transports the bottom pallet SP1 to the next station. The number of pallets is automatically reduced by 1 to 7. This device facilitates the first unpacking operation of a complete set of pallets.

[0016] 2. This automatic pallet unpacking and intelligent pallet quantity identification device works as follows: When there are no pallets at the next workstation, the forks and pallet descend from position SP3 to position SP1. The telescopic cylinder controls the telescopic end to retract, pull the push plate, and the forks to return to their original position and be pulled out of the pallet. Then, the forks are raised to position SP2. The telescopic cylinder and push plate push the forks to extend again and insert into the SP2 pallet, and then move them up to position SP3. At this time, the horizontal conveyor belt runs, transporting the bottom pallet to the next workstation. The number of pallets is automatically reduced by 1 to 6. Subsequent unpacking repeats the two-stage unpacking logic. When the number of pallets is 1 and the forks reach position SP1, the telescopic cylinder and push plate pull the forks to retract back to their original position and then raise them to the SP2 height position to wait for the next set of pallets. This device facilitates continuous automatic unpacking of pallets. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 An automatic tray dismantling and intelligent tray quantity identification device includes two main frames 1. A side high frame 103 is fixedly connected to the inner side of the main frame 1, and a side low frame 104 is fixedly connected to the inner side of the main frame 1. A connecting longitudinal frame 105 is fixedly connected between the side high frame 103 and the side low frame 104. A transport frame 2 is provided between the two main frames 1. A tray dismantling mechanism 4 is provided on the inner side of the two main frames 1 and the connecting longitudinal frame 105 to facilitate automatic quantity identification and tray dismantling. A transmission mechanism 3 is provided between the two main frames 1 to facilitate the lifting and lowering of the tray dismantling mechanism 4 for tray dismantling. A top frame 101 is fixedly connected to the top of the main frame 1, and a support leg 102 is fixedly connected to the bottom of the main frame 1. A rear baffle 106 is fixedly connected between the two main frames 1 and is fixedly connected to the bottom of the top frame 101.

[0025] Please see Figure 5 The dismantling mechanism 4 includes a lifting rail 401, a lifting slide 402, a support plate 403, a slide rail 404, a horizontal slide 405, forks 406, a fixed base 407, a telescopic cylinder 408, a push plate 409, a deceleration position nozzle 410, an arrival position nozzle 411, and a connecting arm 412. The lifting rail 401 is fixedly connected to the inner side of the connecting longitudinal frame 105. The lifting slide 402 is slidably connected to the lifting rail 401. The support plate 403 is fixedly connected to the lifting slide 402. The slide rail 404 is fixedly connected to the upper surface of the support plate 403. The horizontal slide 405 is slidably connected to the slide rail 404. The forks 406 are fixedly connected to the upper surface of the support plate 403. The upper surface of the horizontal slide 405 is connected to the fixed seat 407, which is fixedly connected to the upper surface of the support plate 403. The telescopic cylinder 408 is fixedly connected to the side of the fixed seat 407 facing the fork 406. The push plate 409 is fixedly connected to the lower surface of the fork 406, and the telescopic end of the telescopic cylinder 408 is fixedly connected to the push plate 409. The deceleration position of the dismantling machine is fixedly connected to the nozzle 410 on the inner side of the main frame 1 near the feeding end. The arrival position of the dismantling machine is fixedly connected to the nozzle 411 on the inner side of the main frame 1 near the discharge end. The connecting arm 412 is fixedly connected to one side of the support plate 403. The inner side of the fork 406 is provided with a fork arm, and the fork arm of the fork 406 is slidably inserted into the pallet slot.

[0026] By configuring a lifting rail 401, a lifting slide 402, a support plate 403, and a connecting arm 412, with the connecting arm 412 connected to the transmission mechanism 3, the forks 406 can be moved up and down to switch different heights for pallet dismantling operations. By configuring a telescopic cylinder 408, a push plate 409, and forks 406, the forks 406 can be inserted into or removed from the pallet, controlling the pallet's rise and fall accordingly for dismantling. By configuring a slide rail 404 and a horizontal slide 405, the movement direction of the forks 406 can be limited. The system is configured with a deceleration position for the tray removal machine and a arrival position for the tray removal machine. This allows the horizontal conveyor belt 201 to reduce its speed from high to low after the deceleration position for the tray removal machine senses the tray signal. When the arrival position for the tray removal machine senses the tray signal, the horizontal conveyor belt 201 stops running. If neither the arrival position for the tray removal machine nor the deceleration position for the tray removal machine senses the tray signal, the previous station can then transport the tray with the horizontal conveyor belt 201.

[0027] Please see Figure 4The transmission mechanism 3 includes a crossbeam 301, a support frame 302, a second drive motor 303, a reducer 304, a second transmission rod 305, a driven gear 306, a transmission belt 307, a drive gear 308, a support motor 309, and a lifting belt 310. Two crossbeams 301 are fixedly connected between two sets of main frames 1. The support frame 302 is fixedly connected between the crossbeams 301. The second drive motor 303 is fixedly connected to the upper surface of the support frame 302. The reducer 304 is fixedly installed on one side of the second drive motor 303, and the input end of the reducer 304 is connected to the output end of the second drive motor 303. The upper surface of the crossbeam 301 is fixedly connected to the support frame 302. A rotating bracket is fixedly connected to the second transmission rod 305, which is rotatably connected to the rotating bracket on the upper surface of the cross frame 301. The driven gear 306 is fixedly connected to the side wall of the second transmission rod 305. The transmission belt 307 is connected to the output end of the reducer 304 and the driven gear 306. The drive gear 308 is fixedly connected to both ends of the second transmission rod 305. The support machine 309 is fixedly connected to the upper surface of the side high frame 103. The lifting belt 310 is connected to the drive gear 308 and the support machine 309. The drive gear 308 is a cut-off type, and its two ends are fixedly connected to the upper and lower sides of the connecting arm 412, respectively.

[0028] By setting up a second drive motor 303, a reducer 304, a second transmission rod 305, a driven gear 306, and a transmission belt 307, the second transmission rod 305 is rotated to control the lifting and lowering of the dismantling mechanism 4 to perform the dismantling operation on the pallet. By setting up a drive gear 308, which is located at both ends of the second transmission rod 305, the dismantling mechanisms 4 at both ends can be simultaneously lifted and lowered to perform the dismantling operation when the second transmission rod 305 rotates. By setting up a lifting belt 310, the dismantling mechanism 4 is pulled to lift and lower to switch the height position when the second transmission rod 305 rotates forward or backward.

[0029] Please see Figure 3 The upper surface of the transport frame 2 is provided with two sets of horizontal conveyor belts 201, and the bottom of each set of horizontal conveyor belts 201 is provided with a transmission body 202. The transmission body 202 is internally connected to the horizontal conveyor belts 201. A first drive motor 203 is fixedly installed on one side of the transmission body 202. A first transmission rod 204 is rotatably connected between the two sets of transmission bodies 202. The two ends of the first transmission rod 204 are connected to the input ends of the two sets of transmission bodies 202. A driven wheel set is provided on the side wall of the first transmission rod 204, and the output end of the first drive motor 203 is connected to the driven wheel set on the surface of the first transmission rod 204.

[0030] By setting up a transport frame 2, a horizontal conveyor belt 201 and a transmission body 202, the bottommost pallet that has been removed can be transported to the next work station. By setting up a first drive motor 203 and a first transmission rod 204, the left and right sets of horizontal conveyor belts 201 can be driven to move the pallet at the same speed.

[0031] Working principle: When an automatic tray removal and intelligent tray quantity identification device is used, in the initial state, the side high frame 103, side low frame 104 and connecting longitudinal frame 105 are first set inside the main frame 1. At the same time, a top frame 101 and a rear baffle 106 are connected between the two main frames 1 to support and fix the transmission mechanism 3 and the tray removal mechanism 4. A horizontal conveyor belt 201 is connected to the transport frame 2 set between the two main frames 1. The transmission body 202 at the bottom of the horizontal conveyor belt 201 is driven by the first drive motor 203 and the first transmission rod 204 to move the tray. The tray removal mechanism 4 is connected to the transmission mechanism 3 set inside the main frame 1 so that when the tray removal mechanism 4 is inserted into the tray, the transmission mechanism 3 can control the tray removal mechanism 4 to rise and fall to perform the tray removal operation.

[0032] When automatic pallet unloading is required, the following steps are performed: First, while the pallet is being transported on the horizontal conveyor belt 201, the conveying speed of the horizontal conveyor belt 201 decreases from high speed to low speed after the unloading machine's deceleration position senses the pallet signal at the ejector head 410. When the unloading machine reaches its designated position and senses the pallet signal at the ejector head 411, the horizontal conveyor belt 201 stops running, and the pallet count is set to the maximum of 8. Unloading operations begin when there are no pallets at the next workstation. The initial unloading logic is as follows: the telescopic cylinder 408 extends and pushes the forks 406 through the push plate 409 in the water... The smooth seat 405 and slide rail 404 move under the limit and insert into the SP2 pallet. After the forks 406 are inserted, the second drive motor 303 starts. The working second drive motor 303 drives the second transmission rod 305 to rotate through the reducer 304, transmission belt 307 and driven gear 306. Since the drive gears 308 at both ends of the rotating second transmission rod 305 are connected to the lifting belt 310 and drive it to rotate, the connecting arm 412 connected to the lifting belt 310 is pulled upward by the movement of the lifting belt 310, using the upper The connecting arm 412 pulls the support plate 403 and forks 406 to raise the position to SP3. At this time, the horizontal conveyor belt 201 runs and transports the bottom pallet SP1 to the next station. The number of pallets is automatically reduced by 1 to 7. Secondary pallet dismantling logic: When there are no pallets at the next station, the forks 406 and the pallet start to descend from the SP3 position to the SP1 position. The telescopic cylinder 408 controls the telescopic end to retract, and the traction push plate 409 and forks 406 are reset and pulled out from the pallet. Then, the forks 406 are raised to the SP2 position, and the telescopic cylinder... Cylinder 408 and push plate 409 push the forks 406 to extend again and insert into the SP2 pallet, and lift it up to the SP3 position. At this time, the horizontal conveyor belt 201 runs, transporting the bottom pallet to the next station. The number of pallets is automatically reduced by 1 to 6. Subsequent pallet removal is a repeat of the second pallet removal logic. When the number of pallets is 1 and the forks 406 reach the SP1 position, the telescopic cylinder 408 and push plate 409 pull the forks 406 to retract back to their original position and lift them up to the SP2 height position to wait for the next set of pallets. This device facilitates automatic pallet removal.
