Description

Technical Field

[0001] This invention relates to a pharmaceutical bottle packaging production line, and in particular to a bottle feeding, cap feeding, and cap crimping structure. Background Technology

[0002] In existing technology, bottles are manually placed into a circular turntable within the equipment, which then sequentially guides the bottles onto a conveyor belt. As the turntable rotates, the bottles are propelled closer to the edge of the turntable by a bottle-scraping plate. During the orderly exit of the product along the bottle-scraping grooves of the bottle unscrambler, the bottles slide to the edge of the turntable due to centrifugal force, and are then moved onto the conveyor belt via exit guide grooves located at the edge. However, because centrifugal force can cause the bottles to tip over, the speed of the turntable is limited.

[0003] Traditional lid-scraping bucket structures are slow and have low accuracy. Summary of the Invention

[0004] The problem this invention aims to solve is to overcome the problems in the prior art, such as the easy tipping of medicine bottles on the turntable, low transmission speed, slow cap sorting speed of the cap sorting hopper, and easy production line shutdown.

[0005] The technical solution of the present invention is as follows: A bottle-scraping and capping medicine bottle production line, characterized in that it includes: a bottle-scraping turntable, a hopper, and a cap-scraping hopper, wherein the bottle-scraping turntable includes a turntable frame, several motors, gears, and several conveyor belts, the turntable frame is provided with grooves, the motors and gears are arranged below the turntable frame, the motors drive the gears to rotate, and the gears drive the conveyor belts to move in the grooves of the turntable frame; one side of the conveyor belts is arranged to form the conveying platform of the bottle-scraping turntable; The lid-collecting hopper is located below the hopper and includes an upper vibrating plate and a lower vibrating plate. The upper vibrating plate has a baffle on its circumferential edge and an opening below the baffle. A slide rail extends from the opening to the lower vibrating plate, and the slide rail has a flip-top hole.

[0006] Furthermore, the width of the waist-shaped hole is slightly larger than the radius of the bottle cap, and the length is larger than the diameter of the bottle cap. At least two notches are provided on one side of the flip-top hole.

[0007] Furthermore, the notch spacing is slightly larger than the bottle cap radius, and the sum of the notch width and the notch spacing is greater than the bottle cap diameter.

[0008] Furthermore, the capping mechanism is coaxially configured with an arc-shaped cutting blade and an arc-shaped pressing head component. The arc-shaped cutting blade has a protrusion extending towards the center of the arc, which is used to engage the lower end of the bottle cap with the neck of the medicine bottle. The arc-shaped pressing head component contacts the top of the bottle cap and is used to apply downward pressure to the bottle cap. Attached Figure Description

Detailed Implementation

[0013] Although implementations are described herein by way of example, those skilled in the art will recognize that implementations are not limited to the described examples or figures. It should be understood that the figures and their detailed description are not intended to limit implementations to the specific forms disclosed, but rather, are intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope defined by the appended claims.

[0014] In the production of medicine bottles, it is necessary to quickly and efficiently cap the bottles to complete the sealing of medicine bottles or other containers. To improve efficiency, this invention proposes a medicine bottle production line, which mainly includes four parts: a bottle sorting turntable, a hopper, a cap sorting hopper, and a capping mechanism. The bottle sorting turntable is responsible for sorting and transporting medicine bottles, organizing them in an orderly manner and moving them to the next process, such as a filling machine or capping. The hopper stores bottle caps, and the cap sorting hopper organizes the caps, aligning their orientation before they slide down to the cap drop opening via a cap drop chute. Meanwhile, bottles, after being sorted and transported by the bottle sorting turntable, are moved to the cap drop opening by a conveyor belt, where the caps fall onto the medicine bottle opening.

[0015] Bottle caps are typically made of ductile metal. The bottle opening has a recessed neck, and a capping mechanism presses the lower end of the cap into this recessed neck. Figure 5 As shown, the capping is complete.

[0016] Existing bottle-scraping turntables are typically circular. Connected to a bottle-scraping motor, bottles from the hopper slide down an inclined base onto the turntable. The motor's output shaft is connected to the turntable, driving it to rotate. As the turntable rotates, the bottles move to its edge due to centrifugal force. Bottle baffles prevent bottles from falling off. A bottle outlet guide chute is located at the turntable's edge, guiding bottles from the edge and pushing subsequent bottles along the chute. The outlet of the guide chute connects to a conveyor belt, which moves the bottles to the filling machine.

[0017] Obviously, due to centrifugal force, the bottles are prone to tipping over, and the speed of the bottle unscrambler is limited. For example... Figure 1-2 This invention employs several motors and several conveyor belts. The motors drive the conveyor belts to rotate via transmission gears. One side of the conveyor belts forms the conveying platform of a bottle-sorting turntable, solving the aforementioned problems. This invention includes a turntable frame, motors, transmission gears, and conveyor belts. The turntable frame has a rectangular platform with several slots along its edges. The motors and gears are positioned below the platform frame, driving the conveyor belts. The surface of the belts forms the conveyor belt surface for the medicine bottles. A buffer zone is provided on the platform. When the production line experiences a brief pause, it is not necessary to shut down the platform; bottles conveyed upstream can remain in the buffer zone, thus saving restart time and maintaining production line efficiency.

[0018] Multiple exits can be set around its countertop, and the location of the exits can be set more flexibly.

[0019] The bottle enters the conveyor belt from the outlet and is sent to the capping position.

[0020] At the other end of the production line is the cap sorting mechanism, which sorts the bottle caps, aligns them, and then sends them into the cap dropping chute in an orderly manner, where they slide down to the cap dropping opening and cap the bottle mouth.

[0021] The common cap sorting mechanism is the cap sorting hopper. Existing cap sorting hoppers sort caps by using a feeding spiral line set in the hopper. The hopper is an inverted cone shape with a spiral line on its inner surface. The caps move upwards along the feeding spiral line from below the hopper for sorting. However, its cap sorting efficiency is low, with the maximum cap feeding speed for a single channel or multiple channels only reaching 500 caps / minute, and the sorting accuracy is not high.

[0022] To improve the speed and efficiency of cap sorting and flipping, the technical solution of this invention changes the cap sorting process from a "bottom-up spiral motion" to: the cap slides from the upper vibrating plate to the edge of the disc due to centrifugal force, and then slides from the edge of the disc through a slide to the lower vibrating plate, thus performing cap sorting. Since the vibrating plate has multiple slides that can be set around its circumference, each slide can perform cap sorting (flipping) action. Therefore, compared to the "feeding spiral" and "bottom-up" cap sorting processes, this invention clearly utilizes the cap's own weight and the centrifugal force of vibration to perform cap sorting during the top-down sliding process. This increases the number of sorting channels and significantly improves the cap sorting speed.

[0023] like Figure 3-4 As shown, bottle caps are placed in hopper 7.

[0024] The hopper 7 has a capacity of 20,000-22,000 aluminum caps, which is enough for half an hour. However, the cap sorting hoppers on the market have a small capacity and cannot hold too many aluminum caps, so as not to affect the upward movement of the caps for sorting. Considering a rate of 400 caps / minute, they all need to be equipped with a buffer mechanism to assist in feeding.

[0025] Bottle caps fall from hopper 7 into cap sorting tray 8. The cap sorting tray 8 can act as a buffer during the cap falling process. Sensors are set up to monitor the amount of aluminum caps accumulating, thereby controlling the cap falling speed.

[0026] Only when the aluminum cap is in the cap sorting tray 8 can it enter the cap sorting hopper 9, and the cap sorting hopper will unify the orientation of the cap.

[0027] The lid container includes an upper vibrating plate 91, which is circular and has a baffle on its edge. The baffle has an opening. After the aluminum lid vibrates and slides down from the upper vibrating plate to the circumferential edge, it slides down from the opening through the slide rail 93 to the lower vibrating plate 92.

[0028] The slide 93 is provided with a hole 94.

[0029] like Figure 5 Hole 94 is an oblong hole with two or more notches. The width of the oblong hole (the diameter of the arc at both ends) is slightly smaller than the diameter of the cap. The distance between the two notches is slightly larger than the radius of the cap but smaller than its diameter. The sum of the notch width and the distance between the two notches is greater than the diameter of the cap. This setting ensures that when the cap slides over, the edge of the cap falls on both notches at the same time. When the edge of the cap with the opening facing down slides to both notches at the same time, because the center of gravity of the cap with the opening facing down is unsupported, the cap will flip over and fall into the lower vibrating plate by taking advantage of the fact that the center of gravity of the cap does not coincide with its geometric center. After flipping, it becomes a right-side-up cap, and the opening is adjusted so that the cap opening faces upward.

[0030] Preferably, two or more notches, such as three, can be provided on the straight edge of the waist-shaped hole. The width and position of the notches are set in the same way as the above-mentioned positional relationship. In this way, even if the cover does not fall off when it passes the first two notches, the last two notches on the waist-shaped hole can ensure that the cover with the opening facing down falls off.

[0031] The upper vibrating plate has a smaller diameter than the lower vibrating plate, and the centrifugal force of the upper vibrating plate is smaller than that of the lower vibrating plate. Therefore, when high speed is required, it is necessary to use two or more cover feeding slides to increase the number of covers fed by the upper vibrating plate.

[0032] Furthermore, multiple upper and lower vibrating discs can be set on the same vibrating seat according to actual production needs, providing more cover-sorting tracks and further accelerating the cover-sorting speed.

[0033] The power source for the bottle cap to slide off is the weight of the bottle cap itself and the centrifugal force provided by the vibrating base.

[0034] The upper and lower vibratory plates share the same vibratory base, which provides the power source, such as an eccentric motor, located at the bottom of the upper vibratory plate. The lower and upper vibratory plates are connected by welding, and the two plates share the same vibratory base. All the covers on the vibratory plates will gradually slide to the edge of the vibratory plates due to the centrifugal force of the vibration.

[0035] After being processed, the aluminum cap can be dropped from the cap dropper onto the bottle neck via a cap dropper slide. Then, using the cap crimping device, the lower end of the aluminum cap is engaged with the bottle neck by the cap's elasticity. For example... Figure 6 As shown.

[0036] like Figure 7 , Figure 8 , Figure 9 As shown, the capping mechanism is an arc-shaped cutting tool. When a bottle with an aluminum cap is placed on it, it enters through the bottle conveyor wheel and comes into contact with the cutting edge (protrusion) of the capping mechanism. The cutting edge contacts the lower end of the cap and gradually applies pressure to the lower end of the cap. As the bottle moves along the arc and rotates, the lower end of the cap engages with the neck of the bottle under the pressure of the cutting edge.

[0037] When the medicine bottle enters the arc-shaped cutting blade, the angle of the cutting blade is 5-20 degrees. When the medicine bottle moves to the middle position of the arc-shaped cutting blade, the angle of the cutting blade increases to about 20-60 degrees.

[0038] Furthermore, an arc-shaped pressure head component can be configured to contact the top of the aluminum cap and the top of the bottle cap. During engagement, downward pressure is maintained on the bottle cap.

[0039] The pressure head component has an inclined angle that gradually increases from 20 to 40 degrees when the bottle moves to the arc-shaped inlet end, and gradually decreases from 70 to 50 to 30 degrees when the bottle moves to the arc-shaped outlet position.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
