Description

Technical Field

[0002] At present, an economical Chinese medicine granule filling and packaging line commonly used is like this: the composite film medicine bags packed by the automatic filling and packaging machine are sorted by the sorting machine and stacked into a stack according to the set quantity, and fall into the work station of the servo feeder. The servo feeder conveys the medicine bag to the passing pusher, and the pusher pushes it to the conveyor line of the automatic cartoning machine for the automatic cartoning machine to use for cartoning.

[0003] After searching, the utility model with patent number 201720593524.5 discloses a bagged medicine conveying mechanism, which includes a frame, transmission wheels are arranged at both ends of the frame, a conveyor belt is arranged on the transmission wheel, and a plurality of groups of limit baffles are fixed on the conveyor belt, each group of limit baffles is composed of two fixed plates, and the top of the fixed plate is inclined outward to form a guide surface; the conveyor belt is composed of two chain belts with the same structure, and the chain belt is formed by hinged connection of a plurality of chain links, and a support plate is arranged on the surface of the chain link, and the chain link includes a front hinge shaft, a rear hinge shaft, and a middle tooth plate, wherein the middle tooth plate is divided into two pieces, which are respectively fixed at the two ends of the same side of the front hinge shaft, and a tooth bite area is formed between the two fixed middle tooth plates, and the outer end of the middle tooth plate is fixed with a rear hinge shaft, and the outer end of the rear hinge shaft is fixed with an outer end plate, and the outer end plate and the middle tooth plate are fixed with a support plate, and the fixed plate is fixed on the support plate.

[0004] Although the above patent can realize the function of the servo feeder, it has the following disadvantages:

[0005] 1. The number of medicine packages stacked on the servo feeder is not necessarily correct, sometimes there are more bags or less bags. These more or less bags of medicine packages are sent to the cartoning machine for boxing, causing product quality problems.

[0006] 2. The medicine packages on the servo feeding machine are sometimes stacked in a mess, and the positions of the medicine packages are not correct or skewed. When such medicine packages are pushed by the pusher, the medicine packages are easily damaged, and the pusher is easily damaged. The messy medicine packages will cause quality problems for the finished products after being loaded into the paper box.

[0007] To solve the above problems, a device is needed that can identify the stacking of multiple or fewer bags of medicine packages and the messy stacking of medicine packages, and automatically discharge such multiple or fewer bags or messy stacking of medicine packages from the end of the servo feeder so that they are not pushed onto the cartoning machine by the pusher.

[0008] In order to solve one of the above problems, a servo feeder medicine bag detection device based on a photoelectric sensor is urgently needed. The device can identify the stacking of multiple bags, few bags and messy medicine packages, and cooperate with the existing rejection mechanism to automatically discharge such multiple bags, few bags or messy medicine package stacks from the end of the servo feeder so that they are not pushed onto the cartoning machine by the pusher.

[0021] Four photoelectric sensors are used to detect disordered bags at a single workstation. Each photoelectric sensor consists of a transmitter and a receiver, and is placed at the four corners of the medicine bag stack. Under normal circumstances, the four photoelectric sensors can normally receive light from the transmitter. If a medicine bag at a certain corner is in a disordered position and blocks the light, the photoelectric sensor will not receive the light from the transmitter, and the medicine bag at that workstation will be judged as disordered.
