Description

Technical Field

[0001] The utility model belongs to the technical field of labeling equipment, and particularly relates to a tube dropping device of a labeling machine. Background Art

[0002] A blood collection tube is a vacuum negative pressure blood collection tube. When a patient undergoes a physical examination or other examinations in a hospital, it is usually necessary to collect blood from the patient to facilitate the hospital to obtain the patient's blood sample for further analysis. During the blood collection operation, it is usually necessary for medical staff to prepare corresponding test tubes for the patient and paste labels containing information such as the patient's name, gender, collection date, test type, barcode, etc. on the vacuum blood collection tube.

[0003] Usually, medical staff need to prepare corresponding test tubes for the patient and paste labels corresponding to the test tubes on them. However, manual label pasting is inefficient and not conducive to the patient's rapid completion of blood collection. With the rapid development of technologies such as computers and automation, automatic blood collection tube labeling machines have emerged. Existing blood collection tube labeling machines can achieve automatic distribution of test tubes, automatic generation and pasting of labels. Currently, there are three ways to load blood collection tubes on the market for blood collection tube labeling machines. One is the slide way, that is, the blood collection tubes are arranged and loaded in an inclined slide, and the blood collection tubes slide down under the action of gravity and slide into the label printer to paste the patient barcode label; the second is the drawer way, that is, the blood collection tubes are manually placed in a box in the drawer state, and the blood collection tubes enter the printing and labeling machine through mechanical transmission, and then paste the patient barcode label; the third is the mechanical hand grasping way, that is, the original plastic packaging of the blood collection tube manufacturer is used to load the blood collection tubes, the whole tray is placed in the automatic labeling machine, and the mechanical hand is used to pick up the blood collection tubes and transfer them to the printing and labeling machine to paste the patient barcode label.

[0004] In the actual working process, according to the use requirements, only by controlling the corresponding storage bin to discharge materials, the corresponding type of test tubes can be discharged and transferred to the subsequent labeling mechanism for labeling operation. Although the slide way has the advantages of simple structure and low cost, due to the differences in test tubes of various manufacturers in the market and the differences in different types of blood collection tubes, the state of the blood collection tubes sliding into the printer is uncertain, so it is easy to have faults such as incomplete sliding and tube jamming, and the reliability is poor; although the mechanical hand grasping way has high automation and large loading capacity, it has high cost, and due to high automation, the maintenance work is complex and requires professional personnel for maintenance. Moreover, the main operation of the mechanical hand grasping way is to pick up the blood collection tubes from the blood collection tube tray and transfer them to the printing and labeling machine, and its transfer speed is slow and the efficiency is low. Therefore, it is urgent to design a tube dropping device of a labeling machine to solve the above problems and quickly and accurately discharge the corresponding type of test tubes in the storage bin and transfer them to the subsequent labeling mechanism for labeling operation.
