Description

Technical Field

[0001] This invention relates to the field of ampoule production, specifically to an automated blow molding equipment for mass production of ampoules. Background Technology

[0002] Ampoules are small-capacity, disposable, sealed glass containers used to hold injectable drugs or other products that require extremely high levels of airtightness and sterility. In the pharmaceutical and biopharmaceutical fields, the consumption of ampoules is enormous, with an annual market demand of nearly 40 billion ampoules, accounting for the largest share of the pharmaceutical glass packaging market, far exceeding other forms such as molded bottles and tubular bottles.

[0003] For the production and processing of ampoules, there are many existing ampoule production equipment that can produce 1200 ampoules per minute. This efficient mass production capacity relies on mature automated blow molding production equipment. A complete set of automated blow molding production equipment generally includes a material preparation module, a blow molding and firing module, an inspection module, a feeding module, and an electrical control module. In the entire production process, under the control of the electrical control module, the material preparation module feeds the glass tube material to the blow molding and firing module. On the blow molding and firing module, the glass tube material is blown and shaped, then annealed, and then inspected one by one by the inspection module. Finally, it undergoes cleaning, filling, drawing and sealing processes to complete the production.

[0004] The material preparation module can be further divided into a feeding unit and a gripping and placing unit. The feeding unit prepares the glass tubes for producing ampoules one by one, which are then picked up by the gripping and placing unit. The gripping and placing unit generally uses a programmable robotic arm, which can grip the glass tubes at fixed points and frequencies, and transfer and place them according to a pre-set program.

[0005] In terms of feeding, the existing feeding units, due to their structural design, are limited to serving only one gripping and placing unit. Multiple automated blow molding production equipment require a corresponding number of feeding units, which will increase costs and require more layout space.

[0006] Therefore, an automated ampoule blowing machine for mass production is proposed to address the above problems. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0009] The feeding assembly includes a flared feeding trough, which sits on a base. A rotating roller is provided at the bottom of the feeding trough, which is arranged along the length of the feeding trough. One end of the rotating roller extends through the outside of the feeding trough and is connected to a drive motor. Two material slots are opened on the outer ring of the rotating roller, which are arranged along the length of the rotating roller.

[0010] The bottom outer wall of the feeding trough is symmetrically provided with discharge ports, which are arranged along the length of the feeding trough. A conveying component is provided on the outside of each discharge port.

The toothed discs are rotatably connected to the outer end face of the feeding trough. Each toothed disc has a missing tooth fixedly connected to the same axis. Two adjacent missing teeth mesh together with a gear. The gear is fixedly connected to the rotating roller head to the same axis.

[0013] Preferably, the feeding trough is symmetrically provided with spring pieces, which are arranged along the length of the feeding trough. The spring pieces are located near the inner side wall of the feeding trough, and the edges of the spring pieces are close to the outer surface of the rotating roller.

[0014] Preferably, each discharge port has an extension at its bottom, the extension being arranged along the length of the discharge port, and the edge of the extension being close to the edge of the pallet.

[0015] Preferably, the rotating roller has two through holes inside, both of which are arranged along the length of the rotating roller, and each through hole is arranged on one side of the material trough.

Air supply holes are symmetrically provided on the inner wall of the feeding trough, and each air supply hole is located on one side of the discharge port.

[0017] Preferably, each of the conveyor belts is uniformly provided with a plurality of hollow tubes, which are arranged one by one on the back of the pallet, and each pallet is provided with a plurality of adsorption holes, which are connected to the hollow tubes.

[0018] An adsorption plate is provided between two adjacent conveyor belts. The adsorption plate is arranged parallel to the conveyor belt. A strip-shaped adsorption groove is opened on both sides of the adsorption plate. The adsorption groove is opposite to the ends of multiple hollow tubes.

[0019] Preferably, fixed plates are symmetrically fixed to both sides of the feeding trough, and a rotating shaft is rotatably connected between the two fixed plates on the same side of the feeding trough. A toothed disc is fixed to the end of each rotating shaft, and an actuating pin is provided on the inner end face of each toothed disc. A positioning component is provided between each toothed disc and the adjacent fixed plate. The positioning component is used for the extrusion and positioning of the material, and the positioning component includes a rotating plate rotatably connected to the rotating shaft. The rotating plate is connected to the adjacent fixed plate by a torsion spring.

This further improves material preparation efficiency and provides a stable and efficient supply to the four gripping and placing units. Attached Figure Description

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] Reference Figure 1 - Figure 13 An automated ampoule blowing machine for mass production includes a feeding unit, which comprises a base 1, a feeding assembly, and a conveying assembly. The feeding assembly includes a flared feeding trough 2, which sits on the base 1. A rotating roller 3 is provided at the bottom of the feeding trough 2, which is arranged along the length of the feeding trough 2. One end of the rotating roller 3 extends through the outside of the feeding trough 2 and is connected to a drive motor. Two material troughs 4 are opened on the outer ring of the rotating roller 3, which are arranged along the length of the rotating roller 3. Discharge ports 5 are symmetrically opened on the outer side wall of the bottom of the feeding trough 2, which are arranged along the length of the feeding trough 2. A conveying assembly is provided outside each discharge port 5. Each conveying assembly includes multiple inclined conveyor belts 6, and multiple pallets 7 are evenly provided on the surface of each conveyor belt 6. The pallets 7 are used to lift materials 101 and convey the materials 101 to the top of the multiple conveyor belts 6.

[0046] In this embodiment of the invention, the feeding unit is one part of the automated ampoule blowing equipment, and the feeding unit also includes a support frame 8 for supporting the conveyor belt 6. The drive shaft of the conveyor belt 6 is located on the base plate and connected to a servo motor. The servo motor is connected to an electrical control module.

[0047] The specific operation process of the feeding unit is as follows: multiple materials 101 are placed in the feeding trough 2. The materials 101 are glass tube materials 101. The materials 101 fall down along the side wall of the feeding trough 2. After the materials 101 are embedded in the material trough 4, the drive motor drives the rotating roller 3 to rotate and transfer the materials 101 to one of the discharge ports 5. At this time, the opening of the material trough 4 is tilted downward. The materials 101 are released and roll onto the conveyor belt 6 that is paused on one side of the feeding trough 2. Specifically, they fall onto multiple pallets 7 at the same height. During the process of the materials 101 rolling onto the pallets 7, the opening of another material trough 4 is facing upward and receives another material 101. Then the drive motor drives the rotating roller 3 to reverse and transfer the materials 101 to another discharge port 5. At this time, the materials 101 are released and fall onto the conveyor belt 6 that is paused on the other side of the feeding trough 2.

[0048] The above actions are repeated. After material 101 falls onto pallet 7, conveyor belt 6 moves material 101 up a height, and so on, until material 101 is conveyed to the top position of conveyor belt 6. In this embodiment, the conveyor belts 6 on both sides of the feeding trough 2 are positioned in the middle of the feeding trough 2. When material 101 falls onto conveyor belt 6, both ends of material 101 are exposed. Figure 3and Figure 5 As shown, there are no obstructions. At this time, each top material 101 is symmetrically equipped with a gripping and placing unit 102 on both sides. The two gripping and placing units 102 on the same side of the feeding trough 2 alternately grip the end of the top material 101. At this time, the purpose of one feeding unit can be adapted to four gripping and placing units 102. Each gripping and placing unit 102 is matched with a blowing and firing module 103 on one side. The material is blown and shaped, then annealed, then inspected one by one by the detection module, and finally cleaned, filled, drawn and sealed to complete the production.

[0049] The rotating roller 3 alternately transfers the material 101 to the conveyor belts 6 on both sides of the feeding trough 2, while the two gripping and placing units 102 on the same side alternately grip the material 101 on the top of the conveyor belt 6. Under the control of the electrical control module, the operation is orderly, providing the material 101 in a timely manner for the subsequent large-scale automatic production of ampoules, ensuring that the production of large-scale ampoules can be completed efficiently. Moreover, one feeding unit is compatible with four gripping and placing units 102, saving costs, reducing investment, and reducing the factory floor space occupied.

[0050] Reference Figure 2 - Figure 10 The drive motor and the rotating roller 3 are provided with a transmission mechanism, and the transmission mechanism includes two symmetrical and meshing toothed discs 9. The toothed discs 9 are rotatably connected to the outer end face of the feeding trough 2. Each toothed disc 9 is coaxially fixed with a missing tooth 10. Two adjacent missing teeth 10 mesh together with a gear 11. The gear 11 is coaxially fixed with the head of the rotating roller 3.

[0051] In this embodiment, the drive motor is fixedly connected to one end face of the feeding trough 2. The drive motor is connected to a reducer, and the output end of the reducer is connected to one of the gear discs 9. Adjacent gear discs 9 mesh with each other, such as... Figure 10 As shown, the left toothed disc 9 rotates clockwise, and the right toothed disc 9 rotates counterclockwise. Each toothed disc 9 drives the missing tooth 10 on it to rotate. The missing tooth 10 on the left is about to engage with the gear 11, and the missing tooth 10 on the right is about to disengage from the gear 11. At this time, the rotating roller 3 is in the following state: Figure 7 As shown, the subsequent state of the rotating roller 3 is that the material trough 4 on the right side rotates counterclockwise to face upwards to receive the next material 101, and the material trough 4 that has already received material 101 at the top rotates counterclockwise to the position of the discharge port 5 on the left side.

[0052] In summary, by continuously rotating a drive motor counterclockwise or clockwise, the rotating roller 3 can rotate alternately in both directions, thereby achieving the purpose of alternately supplying material 101 to the conveyor belts 6 on both sides.

[0053] Reference Figure 7The feeding trough 2 is symmetrically provided with spring pieces 12. The spring pieces 12 are arranged along the length direction of the feeding trough 2. The spring pieces 12 are located near the inner side wall of the feeding trough 2, and the edge of the spring pieces 12 is close to the outer surface of the rotating roller 3.

[0054] The spring 12 serves three purposes: first, it guides the material 101 to move upwards on the rotating roller 3 so that the material 101 can fall smoothly into the material trough 4; second, the edge of the spring 12 is close to the surface of the rotating roller 3 to seal the gap between the rotating roller 3 and the feeding trough 2, preventing the material 101 from getting stuck; and third, the edge of the spring 12 can push away excess material 101 from the opening of the material trough 4 and push it upwards on the rotating roller 3, which also reduces the possibility of pushing two materials 101 into the same material trough 4.

[0055] Reference Figure 7 Each of the discharge ports 5 is provided with an extension 13 at the bottom. The extension 13 is arranged along the length direction of the discharge port 5, and the edge of the extension 13 is close to the edge of the pallet 7.

[0056] The extension 13 fills the gap between the discharge port 5 and the pallet 7. The edge of the extension 13 is close to the edge of the pallet 7 but does not contact the pallet 7, ensuring that the material 101 can fall smoothly onto the pallet 7. When the conveyor belt 6 is running, it can effectively transport and lift the material 101.

[0057] Reference Figure 7 - Figure 9 The rotating roller 3 has two through holes 14 inside, both of which are arranged along the length of the rotating roller 3. The through holes 14 are arranged on one side of the material trough 4, and multiple air passages 15 are arranged between the through holes 14 and the adjacent material trough 4.

[0058] Each of the through holes 14 has an extension tube 16 at its edge. The end of the extension tube 16 is attached to the inner wall surface of the feeding trough 2 and rotates. Air supply holes are symmetrically provided on the inner wall of the feeding trough 2, and each air supply hole is located on one side of the discharge port 5.

[0059] Considering that the material 101 starts moving from zero when it falls from the material trough 4 onto the pallet 7, the time it takes for the material 101 to fall onto the pallet 7 is relatively long. This time can be further reduced to improve material preparation efficiency. Specifically, the air supply hole is connected to an external air pump. The air pump injects gas into the air supply hole. When the rotating roller 3 deflects, its extension tube 16 is opposite to the air supply hole, and the gas can be injected into the through hole 14 along the extension tube 16. Then, it is injected into the material trough 4 from multiple air channels 15. At this time, the gas impacts the material 101, giving the material 101 an acceleration and increasing the moving speed of the material 101. This reduces the time spent transferring the material 101, further improving material preparation efficiency and providing a stable and efficient supply to the four gripping and placing units 102.

[0060] Reference Figure 11 - Figure 14 Each of the conveyor belts 6 has a plurality of hollow tubes 17 evenly distributed on its surface. The hollow tubes 17 are arranged one by one on the back of the pallet 7, and each pallet 7 has a plurality of adsorption holes, which are connected to the hollow tubes 17.

[0061] An adsorption plate 18 is provided between two adjacent conveyor belts 6. The adsorption plate 18 is arranged parallel to the conveyor belt 6. A strip-shaped adsorption groove 19 is opened on both sides of the adsorption plate 18. The adsorption groove 19 is opposite to the ends of multiple hollow tubes 17.

[0062] To improve the efficiency of material transfer 101 and thus material preparation, the operating speed of conveyor belt 6 can also be increased to improve the lifting efficiency of material 101. Specifically, the speed of the servo motor driving conveyor belt 6 can be increased. When conveyor belt 6 pauses intermittently, material 101 is unstable on pallet 7 due to its inertia. To address this, adsorption plates 18 are provided. The adsorption plates 18 are hollow inside, and each adsorption plate 18 is connected to an external negative pressure pump through multiple negative pressure pipes. Adsorption holes are opened on both sides of adsorption plates 18, and the adsorption holes are opposite to the ends of hollow tubes 17 on conveyor belt 6, so that the inside of hollow tubes 17 is in a negative pressure state. Thus, the adsorption holes on pallet 7 are also always in a negative pressure state, continuously adsorbing material 101. This further stabilizes material 101 on pallet 7, allowing the material 101 to remain stable on pallet 7 even when the operating speed of conveyor belt 6 is increased or paused intermittently, ensuring that the subsequent gripping and placement unit 102 can accurately grip material 101.

[0063] Reference Figure 6 and Figure 7 ,as well as Figure 15 - Figure 17 The feeding trough 2 is symmetrically fixed with fixed plates 20 on both sides. The two fixed plates 20 on the same side of the feeding trough 2 are rotatably connected with a rotating shaft 21. A toothed disc 9 is fixed to the end of each rotating shaft 21. A toggle pin 22 is provided on the inner end face of each toothed disc 9. A positioning component is provided between each toothed disc 9 and the adjacent fixed plate 20. The positioning component is used for the extrusion positioning of the material 101. The positioning component includes a rotating plate 23 rotatably connected to the rotating shaft 21. The rotating plate 23 is connected to the adjacent fixed plate 20 by a torsion spring 24. An arc-shaped extrusion part 25 is fixed to the end of the rotating plate 23. The extrusion part 25 extrudes the end of the material 101. A web plate 26 is provided on the rotating plate 23. A spring 27 is fixed to the end of the web plate 26. The toothed disc 9 drives the toggle pin 22 to rotate. The toggle pin 22 compresses the spring 27 and drives the rotating plate 23 to deflect around the axis of the rotating shaft 21.

[0064] like Figure 10As shown, the toothed disc 9 on the left rotates clockwise, and the actuating pin 22 on it pushes the spring 27 upward. The elastic force of the spring 27 causes the web plate 26 to drive the rotating plate 23 to deflect clockwise. The rotating plate 23 drives the extrusion part 25 to press the same material 101 at the end, so that the material 101 is in the middle of the same side of the conveyor belt 6, which improves the accuracy of subsequent gripping and placement unit 102 gripping and placing. The toothed disc 9 continues to rotate. When the torque of the torsion spring 24 connected to the rotating plate 23 is greater than the elastic force of the spring 27, the actuating pin 22 can no longer be actuated. The actuating pin 22 disengages from the spring 27. At the same time, under the torque of the torsion spring 24, the rotating plate 23 drives the extrusion part 25 to deflect and reset.

[0065] Similarly, when the right-side toothed disc 9 rotates counterclockwise, the actuating pin 22 on it pushes the spring 27 upward. The elastic force of the spring 27 causes the web plate 26 to drive the rotating plate 23 to deflect counterclockwise. The rotating plate 23 drives the extrusion part 25 to press the same material 101 at the end, so that the material 101 is in the middle of the same side of the conveyor belt 6. This also improves the accuracy of grabbing and placing in the subsequent gripping and placing unit 102. The toothed disc 9 continues to rotate. When the torque of the torsion spring 24 connected to the rotating plate 23 is greater than the elastic force of the spring 27, the actuating pin 22 can no longer be actuated. The actuating pin 22 disengages from the spring 27. At the same time, under the torque of the torsion spring 24, the rotating plate 23 drives the extrusion part 25 to deflect and reset.

[0066] The material 101 on both conveyor belts 6 is adsorbed by the adsorption holes. Even with the interference of the extrusion section 25, the material 101 can still remain stable in the pallet 7.

[0067] Reference Figure 11 - Figure 14 The top of the conveyor belt 6 is provided with a touch switch 28, and the touch head of the touch switch 28 is provided with an arc-shaped dial 29, which extends to the space between two adjacent conveyor belts 6.

[0068] A touch switch 28 is installed on the support frame 8. The touch switch 28 is used to control the pause of the feeding unit. When the material 101 is lifted and moved close to the top of the support frame 8 by the conveyor belt 6, it means that the material 101 on the top of the conveyor belt 6 has not yet been grabbed by the grabbing and placing unit 102. If the conveyor belt 6 continues to transport the material 101, the material 101 will accumulate on the top of the conveyor belt 6, causing an accident. Therefore, the touch switch 28 is installed. When the material 101 moves close to the top of the support frame 8, the material 101 will be squeezed on the deflector plate 29. The deflector plate 29 deflects and squeezes the contact of the touch switch 28. The touch switch 28, in conjunction with the electrical control module, controls the feeding unit to pause, and subsequent problem inspection is carried out. The operation of the feeding unit is stopped in time to reduce losses.

[0069] Reference Figure 8The exhaust direction of each of the air passages 15 is directed towards the upper half of the material 101 in the material tank 4.

[0070] When the exhaust direction of the air passage 15 causes the gas to be discharged, it impacts the upper part of the material 101, generating a downward thrust on the material 101. This allows the material 101 to be quickly transferred to the pallet 7 by following the thrust. When the gas on the pallet 7 acts on the lower or middle part of the material 101, the gas flows along the gap at the bottom of the material 101. The material 101 is isolated by the gas and is in a suspended state. The movement of the material 101 will have a swaying problem, that is, the material 101 may be transferred to the pallet 7 in a tilted state, and the transfer of the material 101 will fail.

[0071] Reference Figure 8 The width of each material trough 4 is greater than the diameter of one material 101 and less than the sum of the diameters of two material 101.

[0072] The size of the opening of the material tank 4 is designed so that multiple materials 101 can enter the material tank 4 at the same time, and the opening of the material tank 4 is set in an flared shape to ensure that the materials 101 can enter smoothly.

[0073] Working principle:

[0074] After material 101 is embedded in the material trough 4, the drive motor drives the rotating roller 3 to rotate and transfers material 101 to one of the discharge ports 5. At this time, the opening of the material trough 4 is tilted downwards, and material 101 is released and rolls onto the suspended conveyor belt 6 on one side of the feeding trough 2, specifically falling onto multiple pallets 7 at the same height. Then, the conveyor belt 6 transports and lifts material 101 to the height to be grasped by the gripping and placing unit 102. Similarly, under the action of the drive motor and the transmission mechanism, the rotating roller 3 reverses and transfers the next material 101 to one of the discharge ports 5. At the other discharge port 5, the material 101 detaches and falls onto the suspended conveyor belt 6 on the other side of the feeding trough 2. The conveyor belt 6 then lifts the material 101 to the height that the gripping and placing unit 102 can grasp. This achieves the goal of one feeding unit adapting to four gripping and placing units 102, providing material 101 in a timely manner for the subsequent large-scale automatic production of ampoules, ensuring that the large-scale production of ampoules can be completed efficiently. Moreover, one feeding unit adapting to four gripping and placing units 102 saves costs, reduces investment, and reduces the factory floor space occupied.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
