Description

A ampoule transfer device for dropproof

Technical Field

The utility model relates to an ampoule transfer device for dropproof especially relates to a dropproof transfer device suitable for transport the volume between two different processes and be 5 to 20 ml ampoules.

Background

An ampoule is a small glass container containing a liquid medicine, and its capacity is usually in the range of 1 to 25 ml. Because of their tendency to break, curved-neck ampoules are the only approved medical ampoules in the medical industry and are manufactured and produced in large quantities in large pharmaceutical facilities. Generally, the production capacity of a set of ampoule production line can reach more than tens of millions, and in the production and manufacturing process of ampoules, various processes such as early stretch forming, bottom cutting forming, cleaning, drying, filling and final encapsulating and detecting after the forming process is completed can be involved, so that the ampoules must be transported among different processes.

Because the finished quantity of each batch of ampoules is more, and the ampoules also have the characteristic that the glass containers are easy to crack, the phenomena of bottle body toppling, breakage, vacancy and instability in the conveying process can be caused by transferring the ampoules among different procedures. To solve this technical problem, those skilled in the art have made various designs and modifications of the inter-process transfer device.

For this reason, patent document CN101121464a provides an intermittent intermediate conveying mechanism, which includes an automatic bottle feeding mechanism, a first conveying mechanism, a second conveying mechanism, and an intermediate conveying mechanism. The automatic bottle feeding mechanism is provided with a coaming and a bottle feeding mesh belt driven by a transmission mechanism, and a slow feeding plate which enables the ampoules to gradually enter into the bottle feeding and poking teeth is arranged above a bottle feeding area of the bottle poking star wheel. The guide surface of the slowly feeding plate towards the automatic bottle feeding mechanism is tangent to the addendum circle of the bottle feeding and poking teeth, so that the ampoule is conveyed to the bottle poking star wheel from the automatic bottle feeding mechanism, and the ampoule input function of the first conveying mechanism is completed. However, in the design of the whole conveying mechanism, an intermediate conveying mechanism with an intermediate conveying toothed plate is further designed, and the intermediate conveying toothed plate is used for conveying the ampoules received by the first conveying mechanism to the strip-shaped conveying toothed plate of the second conveying mechanism at the same beat. The conveying toothed plate not only has a tooth shape and a guide interval for separating the ampoules, but also needs to reciprocate between the first conveying mechanism and the second conveying mechanism, and is provided with the guide plate so as to realize the intermittent conveying of the ampoules.

In summary, this prior art discloses an ampoule transfer device with a complex structure, which not only designs a tooth shape adapted to the ampoule in the automatic ampoule feeding mechanism, but also needs to complete the transfer of the ampoule by combining various mechanisms such as slow feeding, guiding and tooth shifting mechanisms. In particular to a bottle shifting star wheel in an automatic bottle feeding mechanism, which is designed into a tooth-shaped accommodating space matched with the diameter of an ampoule bottle so as to accommodate the ampoule bottle. As a result of this arrangement, different bottle-shifting star wheels, bottle-feeding mechanisms and associated toothed plates need to be designed for ampoules of different diameters or volumes, otherwise, during the rotation of the bottle-shifting star wheels and the linear movement of the strip-shaped feeding plates, the ampoules may slip off from the shifting teeth and the toothed plates.

In order to solve the problem that the ampoules are transported and easily toppled over at the bottle feeding side, patent document CN215622853U proposes another technical scheme, and the ampoules are conveyed to a bottle feeding thumb wheel through a bottle feeding auger. In addition, in order to prevent the ampoule from toppling at the bottle feeding side, the bottle feeding mechanism limiting stopper is designed at the bottle feeding side so as to block and buffer the ampoule entering the bottle feeding thumb wheel at the bottle feeding auger. Because the bottle feeding mechanism limiting stopper positioned on the bottle feeding side can only limit one input ampoule, and the bottle feeding thumb wheel must be designed to be matched with the outer diameter of the ampoule, the limit stopper and the ampoules processed by the bottle feeding thumb wheel are limited, and the limited number of ampoules with fixed diameters can be conveyed in one revolution of the thumb wheel only according to the tooth arrangement and the diameter of the thumb wheel. Not only does this involve a similar problem with the output wheel and the intermediate mechanism barrier as with the bottle inlet wheel, i.e. the number of ampoules delivered during a movement or revolution must be limited by the tooth profile of the wheel and barrier. In this way, the versatility and transport efficiency of the transfer device is limited.

In summary, both of the above prior arts take into account the offset of the input side of the ampoule during the transfer process, and make certain improvements. However, the improvement is only for ampoules with limited outer diameter and peripheral shape, and once the change in the outer diameter or volume of the ampoule results in a large change in the peripheral shape of the ampoule, the ampoule entering the input thumb wheel will also fall over and slip off. And the components involved in the whole transfer process are excessive, so that the maintenance cost of the whole device is increased. Finally, in the whole transfer process, the transfer efficiency of the bottle feeding thumb wheel is simultaneously influenced by the number of the tooth forms, namely, the number of the ampoules which can be transferred during one revolution of the bottle feeding thumb wheel is limited.

The present invention will be described with reference to the accompanying drawings, and it should be understood that the following embodiments are only for illustrating the technical solutions of the present invention, and are not intended to limit the present invention.

Fig. 1 is a schematic diagram of the present invention, showing the basic configuration of an ampoule transfer device for fall protection. The ampoule transfer device for fall prevention can be arranged between any two procedures in the processing and manufacturing process of the ampoules, and is used for transferring the ampoules in large batch. In this embodiment, the fall-off prevention ampoule transfer device may be disposed, for example, between an ampoule cleaning process and an ampoule drying process, or between two processes in an ampoule drying and filling process. Wherein the ampoule transfer device of dropproof includes: the ampoule conveying mechanism comprises an ampoule conveying mechanism 1, a plurality of conveying shifting blocks 15, an inlet anti-falling mechanism 2, a bottle leaning plate 4 and an outlet shifting fork 16.

In this embodiment, ampoule conveying mechanism 1 is the utility model discloses well dropproof ampoule transfer device's main component part has constituted dropproof ampoule transfer device's basis, and its design comes from traditional conveyor belt mechanism. Ampoule conveying mechanism 1 has the bottle of advancing that is located ampoule transfer device and inclines 1A bottle band pulley 11, be located ampoule transfer device's play bottle side 1B first and second play bottle band pulley 12,13 to and be used for connecting ampoule transfer device's the conveyer belt 14 that advances bottle side 1A and play bottle side 1B, carry the ampoule to ampoule transfer device's play bottle side 1B from advancing bottle side 1A. In view of the glass-brittle structure of the ampoule and the durability of the ampoule transport mechanism, the conveyor belt is designed with a double-layer structure, i.e. a plastic wear-resistant damping layer, particularly preferably a plastic layer, is formed on the surface of the metal substrate that contacts the ampoule at the upper part of the conveyor belt. By means of the plastic outer layer structure, the friction force of the ampoule bottle on the conveyor belt is increased, the ampoule bottle is effectively protected, and the ampoule bottle is prevented from being broken possibly caused by collision with the conveyor belt.

More preferably, the ampoule feeding pulley 11 on the ampoule feeding side 1A is configured to have a large diameter to realize low-speed slow feeding of the ampoule, thereby effectively ensuring stable feeding of each ampoule to a designated position; and the double-pulley design of the bottle outlet belt pulleys 12 and 13 positioned on the bottle outlet side 1B improves the conveying speed of the bottle outlet side belt pulleys and ensures that the ampoule bottles quickly leave the current process.

The ampoule conveying mechanism for fall prevention further comprises a plurality of conveying shifting blocks 15 which are distributed at equal intervals on the whole length of the conveyor belt 14 of the ampoule transfer device, so that the ampoules fed from the bottle feeding side 1A of the ampoule transfer device are stored in the containing space surrounded by the two conveying shifting blocks 15 one by one, and the ampoules are conveyed uniformly by means of the conveyor belt 14. The conveyor belts 14 are evenly distributed with the conveyor dials 15 which equally space the ampoules apart from each other, ensuring that each ampoule has a suitable movement range, thereby making it possible to stably transport a large number of ampoules on the conveyor belt 14.

Each delivery paddle 15 is preferably designed as a semicircular structure and is mounted securely on the conveyor belt 14 for separating individual ampoules fed onto the conveyor belt. More preferably, the accommodating space enclosed by two adjacent conveying shifting blocks 15 can accommodate 5-20 ml ampoules, that is, the conveyor belts 14 with the conveying shifting blocks 15 installed at equal intervals can be respectively suitable for conveying ampoules with different volumes, such as 5 ml ampoules, 10 ml ampoules, 15 ml ampoules, and 20 ml ampoules. Most preferably, the conveying block 15 may be a plastic block of nylon construction. The design of the conveying shifting block 15 effectively buffers the rolling of the ampoules in the accommodating space, and avoids the damage possibly caused by the ampoules impacting the conveying shifting block 15 in the conveying process.

The ampoule transfer device for fall prevention also comprises an inlet fall prevention mechanism 2 which is specially arranged at the bottle feeding side 1A of the ampoule transfer device, the inlet fall prevention mechanism 2 is adapted to the peripheral shape of a bottle feeding belt wheel 11 at the bottle feeding side 1A of the ampoule transfer device, and the ampoule which is from a wheel hub W and is sent from the bottle feeding side 1A of the ampoule transfer device is distributed into a corresponding containing space on a conveying belt 14 of the ampoule conveying mechanism 1 in a fall prevention mode. Since the hub W from the previous process continuously outputs a large number of ampoules, a jam may occur on the ampoule feeding side 1A of the ampoule transfer device. The inlet anti-falling device 2 is matched with the bottle feeding belt wheel 11 with a large diameter to feed the ampoules into the containing space separated by the conveying shifting block 15 one by one slowly, so that the ampoule squeezing and crushing caused by the possible inclination and position deviation of the ampoule body on the bottle feeding side 1A and the possible ampoule vacancy on the conveying belt 14 are effectively prevented.

Preferably, the inlet droppreventer 2 has an arc-shaped portion on the side facing the bottle feeding pulley 11, which is wrapped around the bottle feeding pulley 11 in a tangential manner. The skilled person in the practice of the present invention finds that the design of the inlet fall-prevention mechanism 2 with the arc portion further restricts the bottle feeding space between the bottle feeding side 1A and the conveyor belt 14 surrounding the bottle feeding belt wheel 11, and especially restricts the movement space of the conventional large-volume ampoule at the bottle feeding side 1A. Particularly, in the process of feeding a 20 ml ampoule with a curved neck, the top of the ampoule is inclined downwards due to the diameter change of the curved neck towards the top of the ampoule, and the inlet drop-proof mechanism 2 with the arc-shaped part effectively prevents the inclination.

More preferably, the inlet fall arrest mechanism 2 has a thickness of no more than 2.5 mm and a length of no more than 20 mm, and is evenly distributed over the deck 4 at no less than 90 degrees. This configuration makes the inlet fall arrest mechanism 2 particularly suitable for supporting the upper part of the curved neck of a 20 ml ampoule. In particular, the inlet fall protection mechanism 2 may be formed from a molding material, such as polytetrafluoroethylene, to match the contours of the bottle rest plate 4 and the bottle entry pulley 11 of the bottle entry side 1A.

The ampoule transfer device for preventing falling further comprises a bottle leaning plate 4, wherein the bottle leaning plate 4 is matched with the shape of the partial outer contour surrounded by the bottle inlet side 1A and the bottle outlet side 1B of the ampoule transfer device and the conveyor belt 14 positioned between the bottle inlet side 1A and the bottle outlet side 1B, and forms a bottle feeding gap for stably conveying ampoules with the three. The bottle leaning plate 4 and the conveyor belt 14 form an effective bottle conveying path, stable and orderly transfer of the ampoule bottles on the conveyor belt 14 is guaranteed, and jam and intermittent work in the conveying process caused by the fact that the ampoule bottle conveying path is too large are avoided.

Preferably, the thickness of the bottle rest plate 4 on the bottle outlet side 1B is at most 7 mm thicker than the thickness thereof on the bottle inlet side 1A. The thickness of the ampoule leaning plate 4 on the ampoule outlet side 1B is increased, so that the part of the ampoule from the bent neck to the top of the ampoule can be supported and guided by the ampoule leaning plate 4 on the ampoule outlet side 1B, the ampoule can be ensured to roll along the running direction of the conveyor belt around the whole length of the central axis of the ampoule, and the change and the pushing of the movement direction of the ampoule on the ampoule outlet side 1B caused by the lack of support of the upward reducing part of the bent neck of the ampoule are avoided. This is also why the bottle outlet side 1B is not provided with the same entrance fall prevention mechanism 2 as the bottle inlet side 1A.

More preferably, the surface of the bottle rest plate 4 has a textured structure to increase friction and avoid slippage and collision of the ampoules between the conveyor 14 and the rest plate 4 during transport.

The ampoule transfer device for fall prevention is also provided with an outlet shifting fork 16 arranged at the position of the 1B of the bottle outlet side of the ampoule transfer device, the outlet shifting fork 16 and the bottle outlet belt wheel 13 are in clearance fit with the 1A of the bottle outlet side, and the ampoule transferred to the 1B of the bottle outlet side by the conveying belt 14 is transferred to the next procedure. The ampoules still have the rotary motion around self central axis in the linear motion process of following the conveyer belt, and when this kind of uniform motion reaches out bottle band pulley 13, because of the high-speed operation of going out bottle band pulley 13 can produce the inertia that continues the upward motion by its self weight at the moment that the ampoule breaks away from the linear motion of conveyer belt. By providing the outlet fork 16, the ampoule is prevented from jumping upward on the bottle outlet side and is introduced into the inlet of the downstream process. More preferably, the outlet fork 16 has a transition arc on the bottle outlet side tangential to the bottle outlet pulley 13.

To sum up, ampoule transfer device can arrange between two processes in the processing of ampoule and manufacturing process. The ampoule transfer device can be adapted to the transportation of ampoules with large volumes by adjusting the inlet fall prevention device arranged on the bottle inlet side, and is particularly suitable for adjusting the transportation of ampoules transferred from the transportation of ampoules with a volume of 5 ml to ampoules with a volume of 20 ml. The clearance fit between the bottle rest plate and the conveyor ensures a stable running of ampoules of different diameters/volumes on the conveyor in a simple manner, i.e. simultaneously approaching the conveyor in a clearance manner, the bottle inlet side and the bottle outlet side.

Because the ampoule is when entering into the conveyer belt of advancing the bottle side, only the cylindrical position of body can contact with the conveyer belt, consequently when many ampoules are carried the bottle side of advancing to ampoule transfer device through wheel hub simultaneously, can appear that the ampoule emptys and many ampoules extrude each other and the phenomenon of breakage. This phenomenon adversely affects the delivery efficiency and the normal operation of the overall ampoule processing process. The utility model discloses under the prerequisite of the distance between the adjacent two transport shifting blocks of need not adjusting, can adapt to 5 milliliters to 20 milliliters within range different volumetric ampoules from advancing the stable transport of bottle side to play bottle side, avoided various different volumetric ampoules are advancing empting and the landing that bottle side leads to because the body diameter changes, have overcome prior art's defect. Especially, take turns to ampoule transfer device of basis, further improved the efficiency of transporting of ampoule, its highest transport efficiency can reach 300 to 400 ampoules per minute. In addition, the design of standard transport shifting block also makes the maintenance of this ampoule transfer device become convenient.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and do not limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the invention as set forth in the appended claims.
