It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the utility model.

[0032] As Figure 3 shown, a feeding device with a buffer is used to convey the material plate 1. As Figure 1 、 Figure 2 shown, the material plate 1 is a rectangular plate. The upper end surface of the material plate 1 is surrounded by an upper retaining bar 2 parallel to the length or width direction of the material plate 1 to form a placement space for the material fixture. The lower end surface of the material plate 1 is surrounded by a lower retaining bar 4 parallel to the length or width direction of the material plate 1 to form a rectangular frame.

[0033] As Figure 3 shown, a feeding device with a buffer includes: As Figure 4 shown, a first material conveying mechanism 6 is used to convey the material plate 1 transported from the previous station backward (i.e., convey it onto the buffer mechanism). It includes a first conveying mechanism, a pushing mechanism 8 located above the first conveying mechanism, and a first blocking and stopping assembly (not shown in the figure) arranged below the first conveying mechanism to block the forward movement of the material plate 1 on the first conveying mechanism; the structures of the first conveying mechanism and the second conveying mechanism are the same, and both are double-speed chain conveyors; the double-speed chain conveyor includes a pair of driving sprockets, a pair of driven sprockets, two double-speed chains sleeved on the driving sprockets and the driven sprockets, and a third driving member for driving the driving sprockets to rotate. In this embodiment, the third driving member is a first motor; the double-speed chain conveyor is installed on profiles, and baffles are provided on the outer sides of the two double-speed chains of the profiles. The width between the pair of baffles matches the width of the material plate 1 to achieve the guiding of the material plate 1 during transportation on the double-speed chain conveyor. In this embodiment, the double-speed chain conveyor in the first material conveying mechanism 6 is the first double-speed chain conveyor 7, and the double-speed chain conveyor in the second material conveying mechanism 23 is the second double-speed chain conveyor 24. As Figure 5As shown, the pushing mechanism 8 includes a clamping plate 9, a fourth driving member for driving the clamping plate 9 to lift, a fifth driving member for driving the whole fourth driving member to reciprocate along the conveying direction of the material plate 1, and a first guiding assembly for guiding the lifting of the clamping plate 9. In this embodiment, the fourth driving member is a first lifting cylinder 10, and the fifth driving member is a first electric cylinder 11; the first lifting cylinder 10 is fixed on the sliding table of the first electric cylinder 11 through a mounting plate 12, and the clamping plate 9 is fixed on the piston rod of the first lifting cylinder 10 through a connecting plate 13. The clamping plate 9 is a pair of clamping bars arranged in parallel at the edge of the connecting plate 13, and a clamping groove is formed by enclosing the pair of clamping bars and the connecting plate 13; the first guiding assembly includes a plurality of first guiding plates 14 and a first guiding sleeve rod module. Each first guiding plate 14 is vertically fixed on the connecting plate 13, and the side wall of one side is in contact with the side wall of the mounting plate 12. The first guiding sleeve rod module includes a first sleeve 15 fixed on the mounting plate 12 and a first sleeve rod 16 inserted into the first sleeve 15 and fixed at one end on the connecting plate 13; the first guiding assembly ensures the lifting accuracy of the clamping plate 9, and can make the clamping plate 9 accurately clamp on the corresponding upper stop bar 2 on the material plate 1. The first stopping assembly includes a first baffle and a sixth driving member for driving the first baffle to lift. In this embodiment, the sixth driving member is a second lifting cylinder.

[0034] As Figure 6 , Figure 7 shown, the buffer mechanism is used to temporarily store the material plate 1 transported by the first material transporting mechanism 6; it includes a buffer rack 17, a driving assembly for driving the buffer rack 17 to lift, and a plurality of second stopping assemblies installed on the buffer rack 17 to block the advancement of the material plate 1; as Figure 7As shown in the figure, a plurality of shelves 18 are vertically and equidistantly arranged on the buffer rack 17. Rollers 19 are arranged on each shelf 18, and the axial direction of the rollers 19 is perpendicular to the conveying direction of the material plate 1 on the buffer rack 17; the apex of each roller 19 is higher than the top surface of the shelf 18. The arrangement of the rollers 19 facilitates the forward movement of the material plate 1, enabling the pushing mechanism 8 of the first material conveying mechanism 6 to push the material plate 1 onto the buffer rack 17 with a smaller force; each second stopping component is arranged on one side of each shelf 18 close to the second material conveying mechanism 23. The second stopping component includes a second baffle 20 and a first driving member for driving the second baffle 20 to expand and contract. In this embodiment, the first driving member is a first air cylinder 21; the driving component includes a second driving member and a lead screw assembly. The nut of the lead screw assembly is fixed on the buffer rack 17, and the second driving member drives the screw rod of the lead screw assembly to rotate in place. In this embodiment, the second driving member is a second motor 22. Sensors for detecting the presence or absence of the material plate 1 (not shown in the figure) are arranged on each shelf 18. The controller obtains the signal output of the sensors on each shelf 18 and controls the lifting of the buffer rack 17 according to the presence or absence of the material plate 1 on the shelf 18. That is, when the first material conveying mechanism 6 supplies materials, the second motor 22 drives the buffer rack 17 to lift so that the shelf 18 without the material plate 1 is docked with the first double-speed chain conveyor 7. When the second material conveying mechanism 23 receives materials, the second motor 22 drives the buffer rack 17 to lift so that the shelf 18 with the material plate 1 is docked with the second double-speed chain conveyor 24, thereby realizing the function of the buffer mechanism to buffer the material plate 1 when the first material conveying mechanism 6 transports materials too fast.

[0035] As Figure 8 shown, the second material conveying mechanism 23 is used to convey the material plate 1 in the buffer mechanism backward, and includes a second conveying mechanism and a pulling mechanism 25 located above the second conveying mechanism. The pulling mechanism 25 includes a pulling plate 26, a seventh driving member for driving the pulling plate 26 to lift, an eighth driving member for driving the whole seventh driving member to reciprocate along the conveying direction of the material plate 1, and a second guiding component for guiding the lifting of the pulling plate 26. In this embodiment, the seventh driving member is a third lifting air cylinder 27, and the eighth driving member is a second electric cylinder 28. The third lifting air cylinder 27 is fixed on the sliding table of the second electric cylinder 28 through a fixing plate 29, and the pulling plate 26 is fixed on the piston rod of the third lifting air cylinder 27 through an adapter plate 30; the second guiding component includes a plurality of second guiding plates 31 and a second guiding sleeve rod module. Each second guiding plate 31 is vertically fixed on the adapter plate 30, and the side wall of one side is in contact with the side wall of the fixing plate 29. The second guiding sleeve rod module includes a second sleeve 32 fixed on the fixing plate 29 and a second sleeve rod 33 inserted into the second sleeve 32 and fixed on the adapter plate 30 at one end. The second guiding component ensures the lifting accuracy of the pulling plate 26 and can accurately pull the pulling plate 26 on the corresponding lower stop bar 4 on the material plate 1.

[0036] In this embodiment, the working principle of a feeding device with a buffer is as follows: The double-speed chain conveyor in the first material conveying mechanism 6 keeps working, and the second motor 22 drives the buffer rack 17 to lift and lower, so that the laminate 18 of the blank panel 1 is docked with the first double-speed chain conveyor 7; The material panel 1 conveyed from the previous station is conveyed on the double-speed chain conveyor in the first material conveying mechanism 6 towards the buffer mechanism. When it is conveyed to the preset position, the second lifting cylinder of the first stop component drives the first baffle to rise. The first baffle rises to the side of the lower bar 4 on the material panel 1 to stop the material panel 1; The first lifting cylinder 10 drives a pair of clamping plates 9 to descend, so that the pair of clamping plates 9 are clamped on the upper bar 3 at the leftmost side of the material panel 1. The first electric cylinder 11 drives the first lifting cylinder 10 to move towards the buffer mechanism side, and then pushes the material panel 1 to move onto the laminate 18 of the blank panel 1. The piston rod of the first cylinder 21 of the second stop component extends, driving the second baffle 20 to extend to stop the material panel 1 on the laminate 18 to prevent the material panel 1 from sliding out of the laminate 18.

[0037] The second motor 22 drives the buffer rack 17 to lift and lower, so that the laminate 18 with the material panel 1 is docked with the second double-speed chain conveyor 24, and the second double-speed chain conveyor 24 keeps working; The second electric cylinder 28 in the second material conveying mechanism 23 drives the third lifting cylinder 27 to move towards the buffer mechanism as a whole. When the pulling plate 26 moves to the lower side of the laminate 18 docked with the second double-speed chain conveyor 24 and the pulling plate 26 is located at the side directly below the lower bar 5 at the rightmost side of the material panel 1, the second electric cylinder 28 stops operating. The piston rod of the third lifting cylinder 27 extends, driving the pulling plate 26 to rise to the side of the lower bar 5 at the rightmost side of the material panel 1. The second electric cylinder 28 drives the third lifting cylinder 27 to move as a whole away from the buffer mechanism. The pulling plate 26 pulls the lower bar 4 of the material panel 1 to pull the material panel 1 onto the second double-speed chain conveyor 24. Then the piston rod of the third lifting cylinder 27 retracts to drive the pulling plate 26 to descend, and the second double-speed chain conveyor 24 sends the material panel 1 to the next station.
