In this embodiment, the rotary bin 42 is composed of 10 cylindrical storage trays 421, the thickness of the storage trays 421 is 2.5 times the diameter of the part, and 10 cylindrical storage levels 422 are uniformly distributed on the cylindrical surface of the storage trays 421 along the circumferential direction, in other words, 10 rows of 10 storage levels 422 are arranged in the circumferential direction of the rotary bin 42 in this embodiment, and 100 storage levels 422 are required to be formed, and the volume of the storage levels 422 is slightly larger than the volume of the part so that the part from the guide slot 411 of the guide plate 41 can slide into the storage levels 422 smoothly. The blanking assisting device 43 for assisting the parts in the rotary bin 42 to fall into the tray 20 conveyed on the tray conveying device 10 includes a rotary bin wall 431, the rotary bin wall 431 for preventing the parts in the storage level 421 from sliding outward at an improper position. The rotary bin wall 431 is fixedly connected with a blanking auxiliary unit 432, N blanking ports 4321 are arranged on the blanking auxiliary unit 432, N is larger than or equal to 2, N is a natural number, the inlets of the blanking ports 4321 are in one-to-one correspondence with the storage levels 422 of the rotary bin 42, and the outlets of the blanking ports 4321 are in one-to-one correspondence with rectangular grooves of the plastic sucking discs 26 placed on the material disc 20. In the present embodiment, 10 blanking ports 4321 are provided on the blanking auxiliary unit 432. Meanwhile, two sides of the rotary bin 42 are respectively connected with a large gear 44, one side of the two large gears 44 away from the rotary bin 42 is respectively connected with a damper 45, and the damper 45 is used for preventing the two large gears 44 from rotating by the weight of the parts in the rotary bin 42. The automatic loading device 40 further comprises two connecting plates 46, the middle parts of the connecting plates 46 are arranged on the rotating shafts of the rotating bins 42 in a penetrating manner, the upper ends of the connecting plates 46 are connected with the side walls of the guide plates 41 and fixed on the inclined plates 311 of the inclined frames 31 of the automatic material arranging device 30, and the lower ends of the connecting plates 46 are connected with the rotating bin walls 431 of the blanking auxiliary devices 43.

In one embodiment, the automatic parts loader power is activated to manually deposit the parts into the parts magazine 331 of the automatic organizer 30, and because the automatic organizer 30 is disposed obliquely above the tray conveyor 10, the parts will automatically move under their own weight in the direction of inclination of the square bucket 32 toward the automatic loading device 40 downstream of the square bucket 32. During the part sliding down process, the plurality of loose pieces 3311 upstream of the part bin 331 disperse the parts to the plurality of separation cones 3312 downstream of the part bin 331, the separation cones 3312 separate the parts individually from each other into the respective part runners 3321, and the parts further slide down in the part runners 3321 toward the automatic loading device 40 downstream of the side hopper 32. It should be noted that, in order to facilitate the operation of the automatic charging device 40, the single part slide 3321 only allows the single-row parts to slide in the direction of the automatic charging device 40 in turn from the head to the tail, but in the actual operation process, a plurality of stacked parts slide 3321 slide together or tilt up, which affects the operation of the subsequent automatic charging device 40, and in order to avoid this, a pushing structure 34 is disposed above the part slide 3321 to push the stacked or tilted parts into the part slide 3321. The material arranging motor 3422 in the material pushing structure 34 operates and drives the two eccentric turntables 3421 connected with the material arranging motor to rotate, the connecting rod 3423 between the two eccentric turntables 3421 also rotates along with the eccentric turntables, and further drives the push rod 3424 fixed on the connecting rod 3423 to move back and forth in a reciprocating manner, so that the push plate 3414 connected with the push rod 3424 also moves back and forth repeatedly within the range defined by the two push plate limiting rods 3411, and in the forward movement process of the push plate 3414, the horizontal plate 3414c parallel to the part slideway 3321 pushes redundant or tilted parts in the single part slideway 3321 to other part slideways 3321 or parts in the same part slideway 3321, and the parts pushed to the part slideway 3321 continue to slide down towards the automatic charging device 40 under the action of self gravity. The parts in the part slide 3321 eventually slide under their own weight into the corresponding guide slots 411 on the guide plate 41 of the automatic charging device 40 and then slide into the corresponding storage locations 422 of the rotating bins 42.

After the throwing of the parts to be palletized is completed, the rectangular plastic sucking disc 26 is manually and fixedly placed on the tray 20 according to the position of the limiting block 25 on the tray 20, 3-4 trays 20 which are also placed with the plastic sucking disc 26 are placed on the transmission belt 1122 of the tray conveying structure 11 once again, the tray motor 113 is started, the gear transmission assembly 1121 operates, and the transmission belt 1122 sleeved on the gear transmission assembly 1121 is driven to convey the tray 20 to the upstream inlet of the tray pushing structure 12. The previous tray 20 on the support plate 1212 of the pushing support base 121 of the tray pushing structure 12 is slowly moved toward the automatic loading device 40 by the pushing of the next tray 20, and when the previous tray 20 reaches the position below the rotating bin 42, the tray in-place detecting sensor 1252 of the tray detecting unit 125 detects that the tray 20 is in place, and at this time, the tray motor 113 stops operating, and the tray pushing structure 12 starts operating. The X-direction motor 1221 in the tray pushing structure 12 operates at a set speed, and after the X-direction slide block 1223 carrying the Z-direction servo cylinder 134 moves to the stopper 25 of the tray 20 on the X-direction slide table 1222, the Z-direction slide rod 1242 on the Z-direction servo cylinder 1241 is lifted, and the pushing rod 1232 connected to the Z-direction slide rod 1242 passes through the elongated hollow slot 1214 on the support plate 1212 of the pushing support base 121 to make surface contact with the stopper 25 of the tray 20. Subsequently, the X-direction slider 1223 moves toward the automatic loading device 40 under the action of the X-direction motor 1221, in which process the pushing rod 1232 pushes the tray 20 slowly toward the automatic loading device 40, the racks 23 on both sides of the tray 20 pushed slowly are respectively engaged with the two large gears 44 of the automatic loading device 40, and the large gears 44 rotate counterclockwise at a certain speed in the process of being engaged with the racks 23, thereby driving the rotating bin 42 connected with the two large gears 44 to rotate. While the rotary bin 42 rotates, the parts in the guide slots 411 slide down into the storage level 422 of the rotary bin 42 under the action of self gravity and rotate with the rotation of the rotary bin 42. When the storage level 422 with the parts rotates to the opposite side of the guide slot 411, the parts in the storage level 422 start to slide outwards under the action of gravity, but are limited by the rotating bin wall 431 of the auxiliary blanking device 43, the rotating bin 42 continues to rotate, and when the parts in the storage level 422 on the rotating bin 42 are in butt joint with the blanking port 4321 of the auxiliary blanking device 43, the parts in the storage level 422 start to slide and slide from the rotating bin 42 to the corresponding rectangular grooves 261 in the plastic sucking disc 26 on the material disc 20 through the corresponding blanking ports 4321. And then the rotary bin 42 continues to rotate, the parts in the guide slots 411 continue to slide down to the corresponding storage positions 422 on the rotary bin 42 in sequence, and along with the rotation of the rotary bin 42, the parts in the storage positions 422 slide down to the tray 20 until all the parts are completely packed.

It should be noted that, during automatic loading of the parts, when the tray in-place sensor 1252 detects that the loading of the tray 20 is completed, the tray motor 113 continues to operate to push the tray 20 on the conveyor belt 1122 of the tray conveying structure 11 toward the tray pushing structure 12, so as to push the tray 20 that is still on the pushing support base 121 of the tray pushing structure 12 and after the tray 20 that has completed the loading operation continues to move toward the automatic loading device 40. When the tray in-place sensor 1252 again detects that the tray 20 is in place, the tray motor 113 is again stopped and the tray pushing structure 12 is restarted. When the tray 20 with the completed parts being palletized moves to the downstream outlet of the tray pushing structure 12 under the pushing action of the tray 20 with the completed parts being palletized, the full tray sensor 1253 will detect the tray 20 with the completed parts being palletized, in other words, the tray 20 with the completed parts being palletized and the tray 20 with the completed parts being palletized to be palletized will be sequentially swung on the supporting plate 1212 of the supporting base 121 from the upstream inlet to the downstream outlet, at this time, the tray pushing structure 12 will stop working, and the full tray sensor 1253 will give out an audible and visual alarm to prompt the manual removal of the tray 20 with the completed parts being palletized. After the completed loading of the tray 20 is manually removed, the tray pushing structure 12 continues to operate. The function of the tray shortage sensor 1251 is as follows: whether the tray 20 is in place is detected within a set time, if the tray absence sensor 1251 does not detect the presence of the tray 20 within the set time, the tray absence sensor 1251 will send out an audible and visual alarm to prompt manual placement of the tray 20, and after the tray 20 is placed in place, the audible and visual alarm sent by the tray absence sensor 1251 automatically disappears.
