[0026] The utility model is further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 11As shown, the conveyor 4.6 is provided with a separation mechanism at both ends, the separation mechanism includes a transmission chain 2.1, a folding fork group 1, and a fork deployment baffle 3.1. A plurality of folding fork groups 1 are provided inside the transmission chain 2.1. A fork deployment baffle 3.1 is provided on the side of the end of the folding fork group 1 close to the conveyor 4.6. One end of the fork deployment baffle 3.1 is connected to a driving mechanism 1 3.2. When in use, the driving mechanism 1 3.2 uses a cylinder or a motor, and the driving mechanism 1 3.2 drives the fork deployment baffle 3.1 to extend and retract, thereby deploying the forks 1.4 of the folding fork group 1.

[0028] The folding fork set 1 includes a bracket, a spring, a fork, and a connecting rod. The front and rear ends of the bracket 1.1 are fixed on the transmission chain 2.1. The front and rear ends of the bracket 1.1 near the conveyor 4.6 are respectively connected to the fork 1.4. The two forks 1.4 are connected by a connecting rod 1.5. The connecting rod 1.5 is connected to one end of the spring 1.3, and the other end of the spring 1.3 is fixed to the bracket 1.1. The expansion and contraction functions of the two forks 1.4 are realized through the spring 1.3 and the connecting rod 1.4.

[0029] The top of the fork deployment baffle 3.1 is provided with an inclined surface structure 3.7 to play a guiding role. The forks 1.4 of the folding fork set 1 slide along the inclined surface structure 3.7 to the side of the fork deployment baffle 3.1 to achieve the deployment state.

[0030] An arc-shaped fork angle guide groove 3.3 is provided on the side of one end of the transmission chain 2.1 close to the conveyor 4.6, and the front and rear ends of the folding fork assembly 1 pass through the fork angle guide groove 3.3 under the action of the transmission chain 2.1. The fork angle guide groove 3.3 is fixed in the housing 4.1.

[0031] like Figure 10 to Figure 11 As shown, a housing 4.1 is provided outside the transmission chain 2.1 and the folding fork assembly 1, and a through hole 4.8 is provided on the housing 4.1 for the fork unfolding baffle 3.1 to enter and exit. A hole 4.7 is provided on one side of the housing 4.1 for the fork 1.4 to extend.

[0032] A guide groove 3.5 is arranged on the outside of the transmission chain 2.1, and guide wheels 1.2 matching the guide groove 3.5 are arranged at the front and rear ends of the bracket 1.1 respectively, so as to make the folding fork set 1 pass through the guide groove 3.5 smoothly.

[0033] Sprockets 3.4 are provided at the upper and lower parts of the transmission chain 2.1, respectively. The sprocket 3.4 at the lower part is connected to the driving mechanism 2 4.4 through the transmission shaft 4.3. The sprocket 3.4 is fixed through the bearing seat 3.6. A driving mechanism 3 4.5 is provided on one side of the conveyor 4.6. When in use, the driving mechanism 2 4.4 and the driving mechanism 3 4.5 can be motors.

[0034] In the present invention, the left and right shells 4.1 and the components inside the shells 4.1 are also arranged in left-right symmetry.

[0035] In the present invention, before a new pallet stack enters, the fork unfolding baffle 3.1 is controlled to retract by the driving mechanism 1 3.2, at which time the forks 1.4 of all folding fork groups 1 are in a retracted state, and the new pallet stack enters the conveyor 4.6 area without obstruction. After confirming that the pallet stack enters the preparation area, the driving mechanism 1 3.2 pushes the fork unfolding baffle 3.1, and the fork baffle pushes the unfolding folding fork group 1, and the forks 1.4 unfold and enter the second and third layers of pallets at the bottom, playing a bearing role for the pallets. Then, the plurality of folding fork groups 1 rotate in the reverse direction for a short distance until the pallet at the bottom 1st layer is conveyed out, and then the plurality of folding fork groups 1 enter the forward rotation operation state, and the forks 1.4 of the subsequent folding fork groups 1 are guided by the inclined structure 3.7 of the fork unfolding baffle 3.1 to be unfolded, inserted into the lower end of the pallet, and carry the pallet, and after the forks 1.4 leave the fork unfolding baffle 3.1, they are folded and retracted into the outer shell 4.1 under the action of the spring 1.3, and separated from the pallet 5, and the pallet 5 is conveyed out by the conveyor 4.6 until all the pallets 5 are conveyed out by the conveyor, and the operation is completed.

[0036] During the separation of the bottom pallet, since the fork 1.4 corresponding to the pallet bears the weight of the pallet stack, even when the fork 1.4 leaves the fork deployment baffle 3.1, the fork 1.4 cannot be retracted. Figure 5 , Fig. 9 As shown, the utility model sets an arc-shaped fork angle guide groove 3.3 on the side of the transmission chain 2.1. When the folding fork group 1 passes the top of the fork angle guide groove 3.3, the angle of the head of the fork 1.4 is lifted, and the head is in an inclined state with a high head and a low tail. The head of the fork 1.4 lifts the pallet 5, ensuring that the tilted fork 1.4 plays a bearing role on the pallet 5. Then the folding fork group 1 rotates forward, and when the folding fork group 1 passes the bottom of the fork angle guide groove 3.3, the angle of the head of the fork 1.4 falls, and the head is in an inclined state with a low head and a high tail, driving the pallet downward, so that the bottom pallet falls on the conveyor 4.6, and is separated from other pallets on the upper layer, and at this time, the bottom fork 1.4 no longer bears the weight of the entire pallet stack. Then, the fork 1.4 leaves the fork expansion baffle 3.1 and folds and shrinks under the action of the spring 1.3.

[0037] The end of the fork 1.4 that contacts the pallet 5 is the fork head, and the other end of the fork 1.4 is the fork tail.
