At this time, the roller assembly 311 conveys the bottommost empty box to a position facing the transfer mechanism, and then completes one working cycle of the process.

The bottommost empty boxes are always separated from all empty boxes on the bottommost empty boxes through the cooperation among the lifting assembly 312, the clamping assembly 313 and the roller assembly 311 and the circulation of the working process, so that the stacked empty boxes are separated one by one, and a single empty box process is formed for filling the empty boxes with workpieces.

Because the empty box conveying mechanism 1 is used as the feeding end of an empty box, the full box conveying mechanism 2 is the discharging end of a full box, the empty box conveying mechanism and the full box are arranged in parallel (as shown in fig. 1), the stacked empty boxes and the stacked full boxes are separated by adopting the same box separating mechanism 3, however, the transit conveying mechanism 4 and the empty box conveying mechanism 1 are respectively and oppositely arranged at two sides of the box separating mechanism 3, and the three are just arranged corresponding to each other. Therefore, the full-tank separating mechanism 32 must have both a full-tank separating function and a turning function, so that the full-tank separated one by one can be conveyed to a position facing the full-tank conveying mechanism 2.

Specifically, as shown in fig. 7, the full-tank separating mechanism 32 includes a full-tank steering assembly 321, a full-tank adjusting assembly 322 disposed on the full-tank steering assembly 321, and a full-tank separating assembly 323 disposed on the full-tank adjusting assembly 322, where the full-tank steering assembly 321 is used for conveying a full-tank tray to a position opposite to the full-tank conveying mechanism 2, and the full-tank adjusting assembly 322 can adjust the full-tank separating assembly 323 according to the size of the full tank, so that the full-tank separating assembly 323 separates stacked full tanks one by one. Since the full tank dividing assembly 323 and the empty tank dividing mechanism 31 have the same structure, they are not described in detail herein.

After the stacked full boxes are conveyed onto the full box sub-box assembly 323 through the transfer conveying mechanism 4, the full box steering assembly 321 integrally conveys the stacked full boxes to a position opposite to the full box conveying mechanism 2, the upper surfaces of the rollers 134 of the full boxes at the bottommost layer and the full box conveying mechanism 2 are kept flush, and then the full box sub-box assembly 323 separates the stacked full boxes one by one through the full box sub-box assembly 323, and the single full boxes are conveyed out through the full box conveying mechanism 2, so that the whole guarantee and conveying process of workpieces through the box body are completed.

In this way, one driving motor can realize the movement of the second platform 3214 and all the components thereon, and the device has simple structure and convenient use.

Since the full tanks have various shapes and sizes, in order to improve the versatility of the apparatus, it is necessary to separate the stacked full tanks one by adjusting the full tank sub-tank assembly 323 according to the size of the full tank so that the full tank sub-tank assembly 323 separates the stacked full tanks one by one. Specifically, as shown in fig. 8, the full tank adjusting assembly 322 includes a second rail 3222 and an adjusting drive source 3221, an adjusting transmission assembly, and two third platforms 3223, all of which are disposed on a second platform 3214. If the size of the full tank is large, the adjustment driving source 3221 can drive the third platform 3223 to move along the second guide rail 3222 in a direction away from each other through the adjustment transmission assembly, so that the full tank separating assembly 323 is convenient for clamping the full tank. Conversely, if the size of the full tank is small, the adjustment drive source 3221 can drive the third platform 3223 to move along the second guide rail 3222 toward each other through the adjustment transmission assembly.

Specifically, the adjusting driving source 3221 is specifically an adjusting driving motor, the adjusting transmission assembly specifically includes an adjusting driving wheel, an adjusting driven wheel 3123 and an adjusting screw 3124 coaxially disposed with the adjusting driven wheel 3123, which are disposed at an output end of the adjusting motor driving source, and the adjusting driving source 3221 drives the adjusting driving wheel to rotate and transmit the rotation to the adjusting driven wheel 3123 through an adjusting endless belt, and drives the adjusting screw 3124 to rotate. Along with the rotation of the adjusting screw 3124, the adjusting screw 3124 is respectively connected with the two third platforms 3223 through two adjusting screw nuts, and the two adjusting screw 4 nuts are installed in an orthodontic and anti-dental mode, so that the two third platforms 3223 move along the second guide rail 3222 in opposite directions, and the full box sub-box assembly 323 is arranged on the third platforms 3223, so that the clamping stability of the full box sub-box assembly 323 to a full box is improved.

As shown in fig. 9, the transfer conveyor 4 can not only convey a single empty box to a preset position for filling the empty box with workpieces, but also convey a stacked full box to a position facing the box separating mechanism 3. Specifically, the transfer conveying mechanism 4 includes a working box 41, a transfer lifting assembly 42 disposed on the working box 41, and a transfer roller assembly 43, where the transfer roller assembly 43 is used for carrying a single empty box and a stacked full box, and the transfer lifting assembly 42 is used for driving the transfer roller assembly 43 to move up and down along a vertical direction, and the transfer roller assembly 43 is similar to the empty box roller mechanism 12 in structure, so that details are not repeated herein.
