Problems solved by technology

[0004] In the prior art, when vacuum suction cups are used to grab small packages of traditional Chinese medicine, there is no guarantee that each vacuum suction cup can grab the medicine package, so when the vacuum suction cup is controlled to release the medicine package, there is a problem that falls on the electronic weighing device. The number of medicine packs may not match the number of medicine packs needed, which will affect the medicine filling time
[0005] And the existing electronic weighing device, when the drug bag falls on it, there will be a period of oscillation time with unstable readings, and the weighing error during this period is relatively large
In order to prevent the weighing accuracy of the electronic scale from being affected by the oscillation caused by the dropping of the medicine bag, in the prior art, the sampling calculation is usually performed after the electronic scale is stable; and waiting for the electronic scale to stabilize will also waste the time of grasping medicine and reduce the efficiency of medicine grasping

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] The method for dynamic weighing of traditional Chinese medicine in loose bags and small packages of the present embodiment comprises the following steps:

[0053]1) Control the vacuum suction manipulator to grab the medicine package from the medicine cabinet. The vacuum drug inhalation manipulator can adopt the full coverage vacuum drug inhalation manipulator in the application number 201910614948.9 patent name of a fully covered suction cup array automatic dispensing device and its control method.

[0054] 2) Control the vacuum sucker on the vacuum suction manipulator according to the actual required drug bag quantity R to release the grabbed drug bag, so that the drug bag falls freely into the electronic weighing system below. The electronic weighing system includes electronic scales and settings The medicine receiving tank on the electronic s...

Abstract

The invention discloses a dynamic weighing method for bulk-bag small-package traditional Chinese medicines. The method comprises the following steps: 1) controlling a vacuum medicine suction manipulator to grab a medicine bag from a medicine cabinet; 2) controlling a vacuum suction disc on the vacuum medicine suction manipulator to release the grabbed medicine bag; 3) acquiring a weighing signal of an electronic scale after a delay time t1, calculating the difference between the acquired weighing signal and the weighing signal before the vacuum suction disc releases the medicine bag, judging whether the electronic scale is impacted by the medicine bag according to the calculation result, if the judgment result is that the electronic scale is impacted by the medicine bag, executing the step4 downwards, and otherwise, skipping to execute the step 2; and 4) acquiring the weighing signal of the electronic scale after a delay time t2, and judging the number of the medicine bags on the electronic scale according to the acquired weighing signal. According to the invention, the dynamic weighing method for the bulk small-package traditional Chinese medicine can shorten the weighing time and improve the medicine grabbing efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic medicine cabinets, in particular to a method for weighing traditional Chinese medicine in loose bags and small packages. Background technique [0002] Traditional Chinese medicine has a long history in our country and is one of the three national quintessences of our country. As the precious wealth of the motherland's medicine, Chinese medicine has always been welcomed by the majority of patients. With the development of the times and the continuous progress of science and technology, traditional Chinese herbal decoction pieces are being transformed into new modern Chinese herbal decoction pieces, and small-package Chinese herbal decoction pieces have emerged as the times require. Small-package traditional Chinese medicine has many advantages such as maintaining properties, accurate dosage, easy review, clean and hygienic, convenient dispensing, and improving efficiency. [0003] In the prior a...
