Please refer to fig. 2 to fig. 4, the medicine bag dividing assembly 300 includes a cutter 331, a driving mechanism for driving the cutter 331, an infrared detection mechanism and a control system, wherein when the infrared detection mechanism detects that the package bag moves to the cutting position, the control system sends a control signal to the driving mechanism, and the driving mechanism drives the cutter 331 to move towards the package bag to divide the package bag.

The driving mechanism for driving the cutter 331 to move is a cylinder driving mechanism, and the structure is simple and reliable. The junction between the wrapping bag is equipped with some broken lines, and preferably, the cutting edge of cutting knife 331 is the cockscomb structure, and the cross section of cutting edge is the triangle-shaped of width gradual change to the convenient cutting.

The infrared detecting mechanism and the cutter 331 are disposed at intervals in the feeding direction of the package a, i.e., the direction in which the package a is pulled out by the aforementioned holding jaw 203. Before the jaws 203 grip the package, the jaws 203 and the individual packages are located on either side of the cutter 331. In preparation for cutting, the jaws 203 move toward the package and grip the package, and then the jaws 203 pull the individual packages from one side of the cutter 331 to the other side of the cutter 331 to the cutting position.

Specifically, the pouch segmentation assembly 300 includes a mounting frame 333, the mounting frame 333 includes a laminate having a certain width, and the infrared detection mechanism and the cutter 331 are respectively disposed near two sides of the laminate.

The mounting frame 333 includes a first plate 341 and a second plate 342 arranged at a spacing, and the package is cut between the first plate 341 and the second plate 342; the mounting frame 333 further comprises a third plate 343 spaced from the second plate 342, the third plate 343 being located on a side of the second plate 342 remote from the first plate 341, the cutting blade 331 being mounted to the third plate 343, the cutting blade 331 being located substantially between the second plate 342 and the third plate 343 when at rest; during cutting, the driving mechanism drives the third layer plate 343 to move towards the second layer plate 342, so that the cutting knife 331 is driven to move towards the first layer plate 341, and cutting is achieved.

An elastic piece 335 is disposed between the second layer plate 342 and the third layer plate 343, and the elastic piece 335 applies a force to the third layer plate 343 far away from the second layer plate 342, so that the cutting knife 331 is far away from the first layer plate 341, and when cutting is required, the driving mechanism drives the third layer plate 343 to move towards the first layer plate 341 against the force of the elastic piece 335. In this process, the driving mechanism may further drive the second layer plate 342 and the third layer plate 343 to move together towards the first layer plate 341 through the elastic member 335, so as to achieve cutting.

The second laminate 342 is provided with a second slit 337 penetrating the upper and lower sides thereof, and the cutter 331 is partially accommodated in the second slit 337. In the cutting process of the cutting knife 331, the second slit 337 plays a certain guiding role in the downward movement of the cutting knife 331, and the structural design is quite reasonable.

In order to better divide the package, the pouch dividing assembly 300 includes a pressing member 339, wherein the pressing member 339 is disposed on a side of the second layer plate 342 adjacent to the first layer plate 341, the pressing member 339 is made of an elastic material, for example, made of a soft plastic, and when the package is cut, the second layer plate 342 drives the pressing member 339 to move toward the first layer plate 341, so that the package is clamped between the pressing member 339 and the first layer plate 341, and the cutting knife 331 is further convenient to divide the package.

The number of the pressing pieces 339 is two, the two pressing pieces 339 are respectively arranged at two sides of the cutting knife 331, and when in cutting, the two pressing pieces 339 respectively press the two connected packaging bags, thereby facilitating the force of the cutting knife 331 and realizing smooth cutting.

When the cutter 331 is at rest, the cutting edge of the cutter 331 is higher than the lower side of the hold down 339, thereby avoiding erroneous operation of the cutting edge. Of course, when the cutter 331 is stationary, the edge of the cutter 331 is located in the second slit 337, and all the solutions similar to or the same as the present embodiment are also included in the protection scope of the present invention.

The pouch segmentation assembly 300 further includes an anvil 345 corresponding to the hold down 339, the anvil 345 being supported by the first plate 341 with an anvil slot 347 disposed centrally with the second slot 337 on the anvil 345.

The first laminate 341 is provided with a first slit 349 arranged in a centering manner with the anvil slit 347, so that the cutter 331 can be further pressed down to the anvil slit 347 and the first slit 349 during the cutting process, thereby ensuring the cutting effect. Further, the first slit 349 extends through the upper and lower sides of the first layer 341 to provide a greater cutting travel for the cutting blade 331.

Preferably, the control system controls the movement stroke of the cutter 331. Specifically, the control system further includes a stroke detection mechanism, and when the stroke detection mechanism detects that the stroke of the cutter 331 reaches a certain value, the control system sends a signal to the driving mechanism, and the driving mechanism stops moving. Thereby controlling the movement of the cutting blade 331 and reducing errors.

As previously described, the pouch segmentation assembly 300 includes an infrared detection mechanism for detecting whether the package is moved into place. The infrared detection mechanism comprises an infrared emitter 351 and an infrared receiver 353 which are matched, the adjacent parts of the two independent packaging bags are made of transparent materials, and infrared light sent by the infrared emitter 351 is sent to the infrared receiver 353 through the transparent materials. When infrared receiver 353 receives the infrared light, indicating that package a is pulled into place by jaw 203, the infrared detection mechanism transmits a signal to the control system, the control system transmits a control signal to the drive mechanism, which drives cutter 331 to move toward the package to divide the package.

To mount the infrared emitter, the mounting frame 333 includes a fourth plate 344 spaced from the third plate 343, the fourth plate 344 is disposed on a side of the third plate 343 away from the second plate 342, a mounting post 355 extending lengthwise is disposed on a side of the fourth plate 344 away from the third plate 343, and the infrared emitter is disposed on an upper end of a side of the mounting post 355 away from the cutter 331. The first plate 341 has a receiving cavity 357 on a side thereof away from the second plate 342, and an infrared receiver 353 is disposed in the receiving cavity 357. Thus, the infrared emitter and the infrared receiver 353 are respectively located outside the fourth laminate 344 and the first laminate 341, which are farthest from the mounting frame 333, and provide a sufficient travel path for infrared light, thereby ensuring detection accuracy. The mounting post 355 has a width less than the width of the fourth plate 344, and the fourth plate 344 is provided with a notch 359 for allowing infrared radiation to reach the infrared receiver 353. In the present embodiment, the third layer 343, the second layer 342 and the fourth layer 344 have the same width, and the first layer 341 has a width larger than that of the fourth layer 344, so that corresponding gaps are formed on the third layer 343, the second layer 342 and the first layer 341 for the infrared light to pass through.

The present embodiment also provides a cutting system, which includes at least two pouch segmentation assemblies 300, and at least two pouch segmentation assemblies 300 are arranged in parallel. Therefore, when the medicine is automatically dispensed, different traditional Chinese medicines can be cut at the same time, and the dispensing efficiency is improved.
