[0089] When packing, the gloves are placed between the two side baffles of one of the pre-storage devices 412. The gloves are temporarily limited by the two side baffles 41205 and the downward pressure block 41404 of the downward pressure assembly 414. The work station slide cylinder 42301 moves the corresponding transition module 422 to a position matching the pre-storage device 412. The second pusher pushes the gloves into the transition cylinder 42201, and then the work station slide cylinder 42301 moves the transition module 422 to a position matching the first pusher.

[0090] The first suction cup assembly 32207 of the upper suction cup manipulator 322 moves upward and rotates a certain angle to remove the package from the hopper 31, then places it on the first electric clamp. The lower suction cup manipulator 325 then grasps the package from below. The pulling force of the two suction cup arms opens the package and is then clamped by the first electric clamp. The second rodless cylinder 32104 drives the first electric clamp backward. During this backward movement, the second opening plate and the corresponding paddle module propel the upper and lower lids and two side ears of the package open. During this backward movement, the package is located between the limit frame 32606 and the lateral limiters. After the package moves backward to the loading position, the first box pressing device 326 descends and clamps the package. The second electric clamp moves downward and returns to transport another package. The transition cylinder 42201 extends into the package, and the rack of the first pusher 413 presses against the glove. The transition cylinder 42201 then retracts, placing the glove into the package. The first pusher 413 then returns to its initial position. When the next packaging box is delivered, the first electric clamp pushes the packaging box containing gloves to the next station, that is, the station where the steering assembly 324 is located.

[0091] When one transition cylinder 42201 is packing boxes, the other transition cylinder 42201 is receiving gloves in one of the pre-storage devices 412, thereby achieving alternating box packing and higher efficiency.

The first motor base 22308 is located at one end of the second conveying device 223 away from the first conveying device 222, and is fixedly connected to the output end of the second conveying cylinder 6 installed on the support frame 1. When supporting the packaging box, the two second clamps 22305 at the rightmost end of the two third slides 22301 cooperate to support the packaging box, and the two at the second right end cooperate to support the packaging box, and so on.

[0110] The steering assembly 324 places the packed glove box onto the box support. The two first rotary cylinders 22203 on the first conveyor 222 clamp the box. The first conveying cylinder 5 drives the first conveyor 222 to deliver the box to the side-ear manipulator 28. Simultaneously, the first clamping plate 22204 on the second rotary cylinder 22205 pushes the box previously in the side-ear manipulator 28 away. Then, all the first clamping plates 22204 on the first conveyor 222 are laid flat to remove the next box. The clamping cylinder of the second conveyor 223 raises the second clamping plate 22305 to clamp the box leaving the side-ear manipulator 28. The second conveying cylinder 6 drives the second conveyor 223 to deliver the box to the lower cover bending device 27. After that, all the second clamping plates 22305 are laid flat and returned to remove the next box. The second clamping plates 22305 on the two third slides 22301 are laid flat in opposite directions, but can also be laid flat in the same direction.

[0111] The support frame 1 is also equipped with a second box pressing device 23 that can be raised and lowered to match the packaging box pallet.
