[0037] The specific implementation process of the device of the utility model in the production process is as follows: when the pipe fitting 4 is undergoing anti-counterfeiting and anti-channelling packaging production, the device is started, and the belt conveyor 32 starts to operate. After the front end of the pipe fitting 4 is marked with a two-dimensional code for anti-counterfeiting on the surface by a laser marking device, it enters the belt conveyor 32 and is driven by the belt conveyor 32 to be transported to the right. Under the limitation of the front limit plate 321 and the rear limit plate 322, the pipe fitting 4 marked with the anti-counterfeiting two-dimensional code goes out from the right end of the belt conveyor 32, and enters the rear hopper 212 of the buffer hopper body 21 under the guidance of the front polytetrafluoroethylene auxiliary slide plate 335 and the rear polytetrafluoroethylene auxiliary slide plate 330. When the counting photoelectric sensor 34 and the grating sensor 24 both sense the pipe fitting 4, the device counts by one. When the counting photoelectric sensor 34 and the grating sensor 24 sense five pipe fittings, five pipe fittings have been cached in the rear hopper 212 of the cache hopper body 21, meeting the packaging requirements of one package of pipe fittings. At this time, the front reversing cylinder 332 contracts and drives the front reversing support plate 334 to flip forward under the action of the front reversing connector 333, and the rear reversing cylinder 337 pushes out and drives the rear reversing support plate 339 to flip forward under the action of the rear reversing connector 338. After that, the pipe fittings transported are introduced into the front hopper 211 of the cache hopper body 21 by the front polytetrafluoroethylene auxiliary slide plate 335 and the rear polytetrafluoroethylene auxiliary slide plate 330. Then the rear cache cylinder 233 is pushed out, and under the action of the rear fisheye rod end joint bearing 234, the rear cache flap 235 is driven to open, and the five cached pipes 4 are released to fall into the grid of the chain plate grid climbing conveyor 1. Then the rear cache cylinder 233 returns to its original position and drives the rear cache flap 235 to close. At the same time, the chain plate grid climbing conveyor 1 moves one grid to the upper right. Similarly, when the counting photoelectric sensor 34 and the grating sensor 24 sense five pipe fittings again, five pipe fittings have been cached in the front hopper 211 of the cache hopper body 21, meeting the packaging requirements of one package of pipe fittings. At this time, the front reversing cylinder 332 pushes out and drives the front reversing support plate 334 to flip backward under the action of the front reversing connector 333, and the rear reversing cylinder 337 contracts and drives the rear reversing support plate 339 to flip backward under the action of the rear reversing connector 338. Thereafter, the pipe fittings 4 transported are introduced into the rear hopper 212 of the cache hopper body 21 by the front polytetrafluoroethylene auxiliary slide plate 335 and the rear polytetrafluoroethylene auxiliary slide plate 330. Then the front side buffer cylinder 223 moves to push out, and under the action of the front side fisheye rod end joint bearing 224, the front side buffer flap 225 is driven to open and release the five buffered pipes 4 to fall into the grid of the chain plate grid climbing conveyor 1, and then the front side buffer cylinder 223 returns to its original position to drive the front side buffer flap 225 to close, and at the same time the chain plate grid climbing conveyor 1 continues to move one grid to the upper right, and in this way, the chain plate grid climbing conveyor 1 continuously moves the five pipes in each grid to the upper right and sends them to the vertical packaging machine for packaging. The device action is completed.
