Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a syringe assembly labeling and feeding system. Background Art

[0002] A syringe is assembled by a syringe barrel and a plunger rod. After the syringe is assembled, it needs to be labeled. These tasks are currently completed by an assembly machine and a labeling machine. In order to improve the automation of the equipment, these devices need to be configured with corresponding feeding devices to automatically convey the syringe barrels, syringes, etc. to the designated positions. The shapes of syringe-like materials are irregular. Generally, they are placed in a material tray, and then the material tray is placed in a tray for material preparation to make the materials arranged in an orderly manner. Therefore, during the feeding process, the syringe needs to be taken out from the material tray. The existing feeding and material taking methods often have an intermittent period in the middle and require waiting, resulting in a slow feeding speed and affecting the production line efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a syringe assembly labeling and feeding system with continuous feeding and material taking processes, fast and stable feeding speed.

[0004] The present invention is realized through the following technical solutions:

[0005] A syringe assembly labeling and feeding system includes a frame and a tray conveying assembly, a lateral moving assembly, a material tray transferring assembly, a material tray conveying assembly, a feeding mechanism, and a discharging conveying assembly arranged on the frame.

[0006] The tray conveying assembly is used to convey the tray. The tray is placed with a material tray, and the material tray is provided with a number of feeding holes arranged in rows and columns. Materials such as syringe barrels or syringes are installed in the feeding holes. The size of the feeding holes matches the size of the syringe, so that the flange of the syringe can just be stuck in the feeding holes without falling off. A material tray transferring station is arranged on the tray conveying assembly.

[0007] The front end of the material tray conveying assembly is connected to the material tray transferring station of the tray conveying assembly. The lateral moving assembly is arranged above the material tray conveying assembly and the material tray transferring station. The lateral moving assembly is connected to the material tray transferring assembly to drive the material tray transferring assembly to reciprocate between the material tray conveying assembly and the material tray transferring station. The material tray transferring assembly is used to take out the material tray (loaded with materials such as syringes) from the tray and transfer it from the tray conveying assembly to the material tray conveying assembly. The material tray conveying assembly is used to convey the material tray. A feeding station is arranged on the material tray conveying assembly, and a material supporting mechanism is arranged at the feeding station to eject the materials on the material tray to a certain height to facilitate the feeding mechanism to take the materials.

[0008] The feeding mechanism is connected to the feeding station on the pallet conveying component and is used to pick up the materials at the feeding station. The discharging conveying component is connected to the feeding mechanism and is used to receive the materials picked up by the feeding mechanism. The discharging conveying component is connected to the next process.

[0009] Further, a pallet fixing component is also provided at the pallet transfer station on the pallet conveying component, which is used to block the pallet from moving along with the operation of the pallet conveying component, so as to supply the pallet transfer component to pick up the pallet therein. After the pallet is picked up, the empty pallet is released to make the pallet leave. The pallet fixing component includes two stoppers on the left and right. Each stopper is connected to a material blocking cylinder, and the material blocking cylinder is connected to the pallet conveying component. The two stoppers cooperate to block the pallet from the left and right ends in front of the pallet respectively to fix it. The pallet fixing component can prevent the pallet conveying component from stopping during the pallet picking process, avoiding the problems caused by frequent start-up and shutdown. The stopper can be any shape or structure that can block the movement of the pallet.

[0010] Further, there are two sets of pallet fixing components in the front and back along the running direction of the pallet conveying component. The front set is used to block the pallet to be operated at the pallet transfer station, and the back set is used to block the subsequent pallet from moving so as not to affect the operation of the front pallet, and when the empty pallet at the pallet transfer station needs to be removed, to avoid interference between the two pallets.

[0011] Further, a pallet recycling mechanism is also included. The pallet recycling mechanism is connected to the end of the pallet conveying component and is used to recycle the empty pallets conveyed from the end of the pallet conveying component, so as to stack the empty pallets neatly for easy reuse.

[0012] Further, a pallet carrier recycling mechanism is also included. The pallet carrier recycling mechanism is connected to the end of the pallet carrier conveying component and is used to recycle the empty pallet carriers conveyed from the end of the pallet carrier conveying component.

[0013] Further, the lateral moving component includes a bracket and a driving motor assembly, a lead screw, a transmission nut, a moving block and a guide rod provided on the bracket. The driving motor assembly is in transmission connection with the lead screw. The lead screw is arranged above the pallet carrier conveying component and the pallet transfer station. The transmission nut is screwed on the lead screw. The guide rod is arranged in parallel with the lead screw. The moving block is fixedly connected to the transmission nut and is simultaneously slidably connected to the guide rod. The moving block can slide along the guide rod. The moving block is connected to the pallet transfer component to drive the pallet transfer component to move to pick up and place the pallet carrier. The rotation of the lead screw drives the transmission nut to move, driving the moving block to slide along the guide rod, so that the pallet transfer component moves above the pallet carrier conveying component and the pallet transfer station to pick up and place the pallet carrier.

[0014] Further, the drive motor assembly includes a motor, a driving pulley, a synchronous belt, and a driven pulley. The motor is in transmission connection with the driving pulley. The driven pulley is connected to the driving pulley through the synchronous belt, and the driven pulley is in transmission connection with the lead screw.

[0015] Further, anti-collision blocks are provided at both ends of the lead screw.

[0016] Further, the material supporting mechanism is a material supporting cylinder, which is arranged on the material tray conveying assembly. The material supporting cylinder is used to lift the materials in the material tray row by row or column by column to a certain height for the feeding mechanism to pick up row by row or column by column, so as to improve the feeding speed.

[0017] Further, the feeding mechanism picks up the materials in the material tray row by row or column by column.

[0018] Feeding sensors are provided on both the tray conveying assembly and the blanking conveying assembly to detect whether the trays and material trays are conveyed in place, so as to control the actions of picking up the material trays and materials.

[0019] The working process of the above feeding device is as follows: The tray conveying assembly conveys the tray loaded with the material tray and the syringe. When the tray reaches the material tray transfer station, the previous group of tray fixing components act to block the tray at the material tray transfer station. After the material tray transfer component transfers the material tray loaded with the syringe in the tray to the material tray conveying assembly, the previous group of tray fixing components are released. At the same time, the next group of tray fixing components are clamped. The empty tray moves with the tray conveying assembly to the tray recycling mechanism for recycling. At this time, the next group of tray fixing components are released, and the subsequent tray moves to the material tray transfer station. The previous group of tray fixing components are clamped to block the tray at the material tray transfer station, and the above actions are repeated to pick up the material tray; The material tray loaded with the syringe moves on the material tray conveying assembly. When it reaches the feeding station, the material supporting mechanism at the feeding station lifts the syringe in the material tray row by row or column by column to a certain height. The feeding mechanism picks up the syringe in the material tray row by row or column by column to the blanking conveying assembly, and the blanking conveying assembly conveys the syringe to the next process.

[0020] The present invention separates the tray by successively picking up the material tray through the material tray transfer component and the feeding mechanism, and separates the material tray by picking up the material, so as to achieve the purpose of continuous feeding. The tray conveying assembly and the material tray conveying assembly act as the functions of conveying and transfer operation platforms, enabling the smooth transition of the materials and the continuous operation of each mechanism without waiting; The material is ejected by the material supporting mechanism for convenient material picking, and the row-by-row and column-by-column material picking method improves the feeding speed; The trays and material trays can be smoothly conveyed to the tray recycling mechanism and the material tray recycling mechanism, and automatic recycling is realized, which is convenient for repeated use; This device is suitable for feeding assembled syringes, syringe barrels, and other materials similar to syringes, and can be docked with various packaging equipment such as assembly machines and labeling machines.

Detailed implementation manners

[0032] A syringe assembly labeling and feeding system, as Figures 1 to 3 shown, includes a frame 10 and a tray conveying component 1, a lateral movement component 2, a pallet transfer component 3, a tray fixing component 9, a pallet conveying component 4, a feeding mechanism 6, a discharging conveying component 7, a tray recycling mechanism 5 and a pallet recycling mechanism 8 provided on the frame 10.

[0033] The tray conveying assembly 1 is used to convey the tray 12, in which a material carrier 13 is placed. A number of feeding holes arranged in rows and columns similar to a honeycomb shape are provided in the material carrier 13, and the syringe 14 is installed in the feeding holes. The size of the feeding holes matches the size of the syringe 14, so that the flange of the syringe 14 can just be stuck in the feeding holes without falling off. The tray conveying assembly 1 is an existing conventional conveyor belt or a conveying channel. A number of rollers are provided at the bottom of the conveying channel. The bottom of the tray 12 contacts the conveyor belt, and the rotation of the rollers causes the tray 12 to be conveyed forward. As one implementation, the tray conveying assembly 1 in this embodiment is a conveyor belt.

[0034] A material carrier transfer station 11 is provided in the middle section of the tray conveying assembly 1. The tray recycling mechanism 5 is connected to the end of the tray conveying assembly 1 and is used to recycle the empty tray 12 conveyed from the end of the tray conveying assembly 1, so that the empty trays 12 are neatly stacked for easy reuse.

[0035] The front end of the material carrier conveying assembly 4 is connected to the material carrier transfer station 11 of the tray conveying assembly 1. The lateral movement assembly 2 is arranged above the material carrier conveying assembly 4 and the material carrier transfer station 11. The lateral movement assembly 2 is connected to the material carrier transfer assembly 3 to drive the material carrier transfer assembly 3 to reciprocate between the material carrier conveying assembly 4 and the material carrier transfer station 11. The material carrier transfer assembly 3 is used to take out the material carrier 13 (equipped with the syringe 14) from the tray 12 and transfer it from the tray conveying assembly 1 to the material carrier conveying assembly 4.

[0036] The material carrier conveying assembly 4 is used to convey the material carrier 13. A feeding station 41 is provided on the material carrier conveying assembly 4, and a material supporting mechanism is arranged on the feeding station 41 for ejecting the materials on the material carrier 13 to a certain height to facilitate the feeding mechanism 6 to pick up the materials. The material carrier conveying assembly 4 is a conventional conveyor belt or other continuous or discontinuous conveying mechanisms. As one implementation, the material carrier conveying assembly 4 in this embodiment is a conveyor belt, and components for fixing the material carrier 13 are arranged on the conveyor belt. The material supporting mechanism is a supporting cylinder (not shown in the figure), and the supporting cylinder is arranged on the material carrier conveying assembly 4. The supporting cylinder is used to eject the materials in the material carrier 13 in rows or columns to a certain height for the feeding mechanism 6 to pick up in rows or columns, thereby improving the feeding speed.

[0037] The feeding mechanism 6 is connected to the feeding station 41 on the material carrier conveying assembly 4 and is used to pick up the materials on the feeding station 41. The material carrier recycling mechanism 8 is connected to the end of the material carrier conveying assembly 4 and is used to recycle the empty material carriers 13 conveyed from the end of the material carrier conveying assembly 4. As one implementation, the feeding mechanism 6 in this embodiment picks up the materials in the material carrier 13 in rows or columns.

[0038] The blanking conveying component 7 is connected to the feeding mechanism 6 and is used to receive the materials transferred by the feeding mechanism 6. The blanking conveying component 7 is connected to the next process.

[0039] The tray conveying component 1 can stop running when the pallet transfer component 3 picks up the pallet 13 to facilitate the pallet transfer component 3 to pick up the material, or it can continue to run. When running, the pallet 12 is fixed. As one implementation, Figure 1 、 Figure 2 , in this embodiment, a pallet fixing component 9 for fixing the pallet 12 so that it does not move with the conveying device is provided at the pallet transfer station 11 on the tray conveying component 1. And to further optimize the program, the pallet fixing component 9 is provided with two groups in the front and back along the running direction of the tray conveying component 1. The front group is used to block the pallet 12 to be operated at the pallet transfer station 11, and the pallet 12 does not move with the operation of the tray conveying component 1, so that the pallet transfer component 3 can pick up the pallet 13 therein; the rear group is used to block the subsequent pallet 12 from moving so as not to affect the operation of the front pallet 12, and when the empty pallet 12 at the pallet transfer station 11 needs to be removed, to avoid interference between the two pallets 12. Figures 4 to 6 , the pallet fixing component 9 includes two stoppers 91 on the left and right. Each stopper 91 is connected to a material blocking cylinder 92. The material blocking cylinder 92 is connected to the tray conveying component 1 through a mounting plate 93. The two stoppers 91 cooperate to block the pallet 12 from the front end of the pallet 12 to fix it. The incoming material photoelectric eye can be arranged on the mounting plate 93. The pallet fixing component 9 can enable the tray conveying component 1 not to stop during the process of picking up the pallet 13, avoiding problems caused by frequent start and stop.

[0040] The stopper 91 can be any shape or structure that can block the movement of the pallet 12. For further explanation, Figures 4 to 6 , in this embodiment, the stopper 91 is L-shaped, and the pallet 12 is blocked by the fit of the L-shape with the body of the pallet 12. The stopper 91 only applies resistance in front of the pallet 12, without applying clamping force on the left and right sides. The front and rear groups of stoppers 91 can be arranged oppositely, Figure 4 、 Figure 7 As shown, the four L-shapes surround the pallet 12 at the pallet transfer station 11 to block the pallet 12 at the pallet transfer station 11. At the same time, the two L-shaped stoppers 91 in the rear group can also block the subsequent pallet 12; when the front pallet 12 needs to be released, first release the front group of L-shaped stoppers 91, the pallet 12 is removed, and then release the rear group of L-shaped stoppers 91, and the subsequent pallet 12 moves to the pallet transfer station 11. The front and rear groups of stoppers 91 can also be arranged in parallel, Figure 5, two L-shaped stoppers 91 in the previous group surround the front two corners of the tray body of the tray 12 to block the front tray 12, and two L-shaped stoppers 91 in the latter group surround the front two corners of the tray body of the tray 12 to block the rear tray 12.

[0041] As Figures 8 to 10 , the lateral movement assembly 2 includes a bracket 21 and a drive motor assembly, a lead screw 23, a transmission nut 24, a moving block 25 and a guide rod 26 provided on the bracket 21. The drive motor assembly is in transmission connection with the lead screw 23. The lead screw 23 is arranged above the pallet conveying assembly 4 and the pallet transfer station 11. The transmission nut 24 is screwed on the lead screw 23. The guide rod 26 is arranged in parallel with the lead screw 23. The moving block 25 is fixedly connected with the transmission nut 24. The moving block 25 is simultaneously slidably connected with the guide rod 26. The moving block 25 can slide along the guide rod 26. The moving block 25 is connected with the pallet transfer assembly 3 to drive the pallet transfer assembly 3 to move to pick and place the pallet 13. When the lead screw 23 rotates, it drives the transmission nut 24 to move, driving the moving block 25 to slide along the guide rod 26, so that the pallet transfer assembly 3 moves above the pallet conveying assembly 4 and the pallet transfer station 11 to pick and place the pallet 13. Anti-collision blocks 30 are also arranged at both ends of the lead screw 23.

[0042] As Figure 10 , the drive motor assembly includes a motor 22, a driving pulley 27, a synchronous belt 28 and a driven pulley 29. The motor 22 is in transmission connection with the driving pulley 27. The driven pulley 29 is connected with the driving pulley 27 through the synchronous belt 28. The driven pulley 29 is in transmission connection with the lead screw 23. A protective cover 31 is provided outside the driving pulley 27, the synchronous belt 28 and the driven pulley 29.

[0043] Feeding electric eyes are arranged on both the pallet conveying assembly 1 and the blanking conveying assembly 7 to detect whether the pallet 12 and the pallet 13 are conveyed in place, so as to control the actions of picking the pallet 13 and picking the material.

[0044] The working process of the above feeding device is as follows: The tray conveying component 1 conveys the tray 12 equipped with the tray holder 13 and the syringe 14. When the tray 12 reaches the tray holder transfer station 11, the previous group of tray fixing components 9 act to block the tray 12 at the tray holder transfer station 11. The tray holder transfer component 3 transfers the tray holder 13 equipped with the syringe 14 in the tray 12 to the tray holder conveying component 4. The previous group of tray fixing components 9 are released. At the same time, the next group of tray fixing components 9 act to block the subsequent tray 12. The empty tray 12 moves with the tray conveying component 1 to the tray recycling mechanism 5 for recycling. At the same time, the next group of tray fixing components 9 are released, and the subsequent tray 12 moves to the tray holder transfer station 11. The previous group of tray fixing components 9 act to block the tray 12 at the tray holder transfer station 11, and the above actions are repeated to pick up the tray holder 13. The tray holder 13 equipped with the syringe 14 moves on the tray holder conveying component 4. When it reaches the feeding station 41, the tray supporting mechanism at the feeding station 41 supports the syringe 14 in the tray holder 13 in rows or columns to a certain height. The feeding mechanism 6 picks up the syringe 14 in the tray holder 13 in rows or columns and places it on the blanking conveying component 7. The blanking conveying component 7 conveys the syringe 14 to the next process.

[0045] The above detailed description is a specific description of the feasible embodiments of the present invention.
