[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference below Figure 1-3 , the implementation of the pallet circulation device proposed in the embodiment of the utility model is described in detail.

[0024] The pallet circulation device according to the embodiment of the utility model is arranged on the round cover packaging production line, and comprises: a first material bin 1, a second material bin 2, a first transfer assembly 3 and a second transfer assembly 4.

[0025] Specifically, the first silo 1 is suitable for storing a plurality of pallets 7; the second silo 2 is suitable for receiving pallets 7 to store round cover strips 8, the first transfer component 3 is movably arranged between the first silo 1 and the second silo 2 to transfer the pallets 7 therebetween, the second transfer component 4 is movably arranged between the first conveyor line 5, the second conveyor line 6 and the second silo 2 to transfer the round cover strips 8 therebetween, when the round cover packaging assembly line is in the first state, the second transfer component 4 transfers the round cover strips 8 of the first conveyor line 5 to the second conveyor line 6; when the round cover packaging assembly line is in the second state, the first transfer component 3 transfers the pallets 7 in the first silo 1 to the second silo 2, and the second transfer component transfers the round cover strips 8 on the first conveyor line 5 to the pallets 7 of the second silo 2; when the round cover packaging assembly line is in the third state, the second transfer component 4 transfers the round cover strips 8 in the second silo 2 to the second conveyor line 6.

[0026] That is to say, when the round cover packaging assembly line operates normally (first state), the second transfer assembly 4 transfers the round cover strips 8 on the first conveyor line 5 to the second conveyor line 6, so as to facilitate the subsequent bagging and packaging of the round cover strips 8; when a fault occurs downstream of the first conveyor line 5 and the second conveyor line 6, or the discharge speed of the upstream is faster than the consumption speed of the downstream (second state), the first transfer assembly 3 transfers an empty pallet 7 in the first silo 1 to the second silo 2, and the second transfer assembly 4 transfers the round cover strips 8 on the first conveyor line 5 to the pallet 7 in the second silo 2. When the pallet 7 in the second silo 2 is full, the first transfer assembly 3 continues to transfer the round cover strips 8 from the first silo 1. An empty pallet 7 is sent to the second silo 2 and stacked on the full pallet 7, and the empty pallet 7 in the second silo 2 continues to receive the round cover strips 8 transferred by the second transfer component 4 until the round cover strips 8 on the first conveyor line 5 are transferred, thereby caching the round cover strips 8 to ensure that the upstream equipment continues to operate; when a fault occurs upstream of the first conveyor line 5 and the second conveyor line 6 (the third state), the second transfer component 4 transfers the round cover strips 8 in the second silo 2 to the second conveyor line 6, and the empty pallet 7 is transferred from the second silo 2 to the second silo 2 through the first transfer component 3 until the round cover strips 8 in the second silo 2 are transferred, thereby ensuring that the downstream equipment continues to operate.

[0027] Thus, when the dome packaging line is in the first state, the dome strips 8 on the first conveyor line 5 are transferred to the second conveyor line 6 by the first transfer assembly 3 of the pallet circulation device; when the dome packaging line is in the second state, the pallet 7 in the first bin 1 is transferred to the second bin 2 by the first transfer assembly 3 of the pallet circulation device, and the second transfer assembly 4 transfers the dome strips 8 on the first conveyor line 5 to the pallet 7 in the second bin 2; when the dome packaging line is in the first state, the second transfer assembly 4 transfers the dome strips 8 in the second bin 2 to the second conveyor line 6. The pallet circulation device can continue to operate with the equipment in the normal state to improve the efficiency of the overall production line.

The second lifting drive 22 is connected to the second lifting platform 21 to drive the second lifting platform 21 to move up and down. It can be understood that the second lifting drive 22 drives the second lifting platform 21 to move up and down, so that the second transfer component 4 can transfer the round cover strip 8 on the first conveyor line 5 to the pallet 7 on the second lifting platform 21, and the first transfer component 3 can transfer the pallet 7 above the second lifting platform 21 to the first lifting platform 11. Among them, the second lifting drive 22 can be a motor with a chain and a slide rod structure.

[0030] As for the first transfer assembly 3, the first transfer assembly 3 has a first clamping member 31, a first opening and closing driving member 32 and a first moving driving member 33. The first opening and closing driving member 32 is connected to the first clamping member 31 to drive the first clamping member 31 to open and close to clamp the pallet 7, and the first moving driving member 33 is connected to the first opening and closing driving member 32. It can be understood that the first opening and closing driving member 32 drives the first clamping member 31 to open and close, so as to facilitate the clamping of the pallet 7, and the first moving driving member 33 can move the clamped pallet 7 between the first silo 1 and the second silo 2, so as to facilitate the transfer of the empty pallet 7 in the first silo 1 to the second silo 2 to receive the round cover strip 8, or the transfer of the empty pallet 7 in the second silo 2 to the first silo 1, thereby forming a recycling of the pallet 7.

It can be understood that the second clamping member 41 is driven to open and close by the second opening and closing driving member 42, so as to facilitate the clamping of the round cover strip 8, and the second moving driving member 43 can drive the second clamping member 41 to move between the second silo 2, the first conveyor line 5, and the second conveyor line 6, so as to facilitate the clamping of the round cover strip 8 of the first conveyor line 5 and transfer it to the pallet 7 in the second silo 2, or transfer the round cover strip 8 on the pallet 7 in the second silo 2 to the second conveyor line 6. Among them, the second clamping member 41 can be two long plates cooperated with two push rods, the two long plates clamp from both sides of the round cover strip 8, and the two push rods clamp from both ends of the round cover strip 8; the second opening and closing driving member 42 can be a cylinder structure, and the second moving driving member 43 can be a motor cooperated with gears, racks and moving substructures.
