The embodiment of the utility model provides an automatic feeding device, its concrete structure is as shown in figure 1.

As shown in fig. 1, the automatic loading apparatus includes a full loading station 10, a take-out station 20, and an empty loading station 30. The full load station 10, the take-up station 20 and the empty load station 30 are arranged in sequence on a linear rail 80. The rail 80 has two parallel rails.

As shown in fig. 1, the loading station 10 is used to stack pallets 90 filled with work-pieces. As shown in fig. 1, the full loading station 10 comprises a first cylinder 11 and a rotatable support plate 16. The first air cylinder 11 is arranged below the tray 90, an output shaft of the first air cylinder 11 faces upwards, and the first air cylinder 11 is used for driving the tray 90 on the full-loading station 10 to move up and down. Specifically, the first cylinder 11 is fixed on a horizontal plate 12, an output shaft of the first cylinder 11 is fixedly connected with a bottom plate 13, and the bottom plate 13 penetrates through and is fixed with four ejector rods 14 penetrating through the horizontal plate 12. A horizontal top plate 15 is fixed at the top end of each two ejector rods 14, and the first air cylinder 11 drives the tray 90 on the full-load station 10 to move up and down through the two top plates 15.

The loading station 10 is provided with 4 support plates 16, each 2 support plates 16 being provided on a rail 80. As shown in fig. 1 and 2, each support plate 16 is provided on one base 17, and the bases 17 are fixed to the rails 80. The support plate 16 has at least a support state and a pass-through state. The supporting plate 16 is hinged with a base 17, and a jacking cylinder 18 is arranged in the base 17. The jack-up cylinder 18 has an output shaft connected to the support plate 16, and the jack-up cylinder 18 is used to control the support plate 16 to be rotationally switched between the support state and the pass-through state. When the jacking cylinders 18 are contracted, the support plates 16 are horizontal and in a supporting state, and the outer ends of the 4 support plates 16 support the trays 90 stacked on the full loading station 10. If there is a tray 90 on the rail 80 under the supporting plate 16, the supporting plate 16 separates the stacked tray 90 from the tray 90 under it, so that the tray 90 under it can be moved to another position. When the jacking cylinder 18 extends out, the support plate 16 rotates upwards until the minimum distance between the support plates 16 on the two side rails 80 is larger than the width of the tray 90, and the support plates 16 are in a passing state, the tray 90 stacked on the full loading station 10 can be driven by the first cylinder 11 to move up and down. In operation, the first cylinder 11 is actuated to lift the stacked pallet 90 and the lift cylinder 18 is extended to rotate the support plate 16 to the pass-through position. The first cylinder 11 then moves the tray 90 down, and when the lowermost tray 90 falls below the level of the support plate 16, the jacking cylinder 18 retracts, rotating the support plate 16 back to horizontal. The first cylinder 11 continues to drive the trays 90 to descend, the lowest tray 90 descends along with the first cylinder 11 onto the rail 80 to wait for transferring, and the other stacked trays 90 above are held by the 4 support plates 16.

The takeout station 20 is used for an external robot to grasp a workpiece on the pallet 90. As shown in fig. 1, a fourth cylinder 21 is provided below the reclaiming station 20. The fourth cylinder 21 is fixed to a horizontal plate 22. The output shaft of the fourth cylinder 21 is fixedly connected to a base plate 23. Four carrier rods 24 are inserted and fixed in the bottom plate 23. Each carrier rod 24 extends through the horizontal plate 22. A horizontal top plate 25 is fixed at the top end of each two push rods 24. The fourth cylinder 21 drives the tray 90 on the material taking station 20 to move up and down through the two top plates 25. During operation, the fourth cylinder 21 is started to push the tray 90 on the material taking station 20 to a set height, and the grabbing module 70 of the external manipulator moves to the position above the tray 90 to suck the workpiece on the tray 90 through the vacuum suction nozzle 71. When all the workpieces on the pallet 90 have been removed, the fourth cylinder 21 is retracted to lower the pallet 90 onto the rail 80.

The automatic feeding device also comprises a transfer mechanism. The transfer mechanism is used to move the tray 90 at the lowermost level of the full load station 10 to the takeout station 20 and to move the tray 90 with the work-pieces completely removed at the takeout station 20 to the lowermost level of the empty load station 30. As shown in fig. 1, the transfer mechanism includes a horizontal third cylinder 41 and a push plate 42. The third cylinder 41 is parallel to the rails 80 and is disposed between the two rails 80. The output shaft of the third cylinder 41 is fixedly connected with the push plate 42. The third cylinder 41 is fully extended so that the push plate 42 is at the outer end of the loading station 10, and the first cylinder 11 and the support plate 16 of the loading station 10 are controlled to operate to lower the lowermost tray 90 onto the rail 80. The third cylinder 41 is then retracted, and the pusher plate 42 pushes the tray 90 on the rail 80 at the full loading station 10 to the reclaiming station 20, and the adjacent empty trays 90 on the rail 80 abut against each other, so that the empty tray 90 at the side of the empty station 30 is pushed below the stacking tray 90 at the empty station 30.

In addition, as shown in FIG. 1, a bumper 43 is provided at the end of the stroke of the push plate 42. The damper 43 serves to dampen the kinetic energy of the pusher plate 42 at the end of the stroke.

The idle station 30 is used to stack the pallet 90 with the workpiece completely removed. As shown in fig. 1, the idle station 30 includes a second cylinder 31 and a rotatable support plate 36. The second cylinder 31 is used to drive the tray 90 on the idle station 30 to move upward. The second cylinder 31 is provided below the tray 90 and the output shaft of the second cylinder 31 faces upward. The second cylinder 31 is fixed to a horizontal plate 32, and the output shaft of the second cylinder 31 is fixedly connected to a base plate 33. Four push rods 34 penetrate through and are fixed on the bottom plate 33. Each ram 34 extends through the horizontal plate 32. A horizontal top plate 35 is fixed at the top end of each two push rods 34. The second cylinder 31 drives the tray 90 on the idle station 30 to move upward through the two top plates 35.

The idle station 30 is provided with four support plates 36. As shown in fig. 1, each support plate 36 is provided on a base 37, and the base 37 is fixed to a rail 80. The support plate 36 is hinged to a base 37. The support plate 36 has at least a support state and a pass-through state. The support plate 36 is in a support state when it is horizontal, and the support plate 36 is used to support the tray 90 stacked on the idle station 30. When the support plate 36 is rotated to the passing state, the tray 90 stacked on the full loading station 30 can be driven by the second cylinder 31 to move upward and pass over the support plate 36. In operation, an empty pallet 90 is pushed onto the rail 80 at the unloading station 30, and the second cylinder 31 is actuated to lift the stacked pallet 90. When the bottommost tray 90 is raised, the support plate 36 is pushed upward and rotates about the base 37. The tray 90 at the lowest layer continues to rise, and when the support plate 36 rotates to the passing state, the tray 90 at the lowest layer goes over the support plate 36, and the support plate 36 rotates downward to the horizontal state under the self-gravity. At this time, the second cylinder 31 is retracted, and the stacked empty tray 90 is lowered until the tray 90 is held by the 4 support plates 36, thereby completing the stacking of the tray 90.

As shown in fig. 1, four positioning cylinders 91 are disposed above the tray 90. As shown in fig. 3, four positioning posts 92 are disposed under the tray 90. When the trays 90 are stacked, the positioning columns 92 of the tray 90 located above are inserted into the positioning cylinders 91 of the tray 90 located below, respectively. The top plate 25 of the reclaiming station 20 is provided with positioning holes (not shown) corresponding to the positioning posts 92 of the tray 90. When the top plate 25 jacks up the tray 90, the positioning columns 92 of the tray 90 are inserted into the positioning holes of the top plate 25, so that the accurate positioning effect is achieved.
