Needle tube feeding device and rotary rod labeling machine

Abstract

The invention relates to a needle tube feeding device and a rotary rod labeling machine. The needle tube feeding device comprises a conveying mechanism, a material taking clamping jaw, a pushing mechanism and a temporary storage mechanism; wherein the material taking clamping jaw is movably arranged above the conveying mechanism; the pushing mechanism is matched with the material taking clamping jaw; and the temporary storage mechanism comprises a temporary storage tray, and the temporary storage tray is connected with the pushing mechanism in a linkage manner. Due to the fact that the temporary storage mechanism is used for feeding the needle tube on the previous tray, the material taking clamping jaw can be used for grabbing and taking a new tray filled with the next full needle tube without waiting for time consumption, so that the seamless continuous feeding is realized compared with the traditional technology, the feeding efficiency is higher, the processing continuity of equipment can be ensured, and the production economical efficiency of enterprises is favorably improved.

Description

technical field [0001] The invention relates to the technical field of labeling machines, in particular to a needle feeding device and a rotary rod labeling machine. Background technique [0002] Traditionally, the production process of pre-filled syringes is as follows: the needle bar and the pre-filled needle tube are loaded separately, and then the needle bar and the needle tube are assembled into one body through the rotary rod mechanism, and finally the finished product is completed by labeling. Before loading, multiple needle tubes are usually preloaded into the tray through the tray, and the tray is transported to the clamping station through the conveyor belt, and the multiple needle tubes arranged in an array are simultaneously removed from the tray through the pick-up jaws, and then the pick-up clamp The claws make a horizontal stepping movement, and transfer the needle tubes row by row to the slideway in turn. After all the transfers are completed, the fetching ja...

Problems solved by technology

[0003] However, the traditional feeding method has the following defects: each time when feeding, the pick-up jaws must wait for all the needle tubes on the current tray to be transferred before they can pick up the next tray for connection and feeding. The waiting time of the material gripper is too long, and when the next pallet is moved and clamped, the slideway is in an empty state, which cannot realize continuous and intermittent feeding, resulting in low feeding efficiency and poor continuity of equipment processing
