Technical Field
[0001] This utility model relates to the field of pharmaceutical production and packaging equipment, and in particular to an automatic bottle unscrambler for packaging liquid pharmaceuticals. Background Technology
[0002] Bottle unscrambling is a crucial step in the production and packaging of liquid pharmaceuticals. Its function is to neatly and orderly transport irregularly shaped bottles to subsequent processes such as filling and sealing. While existing automated bottle unscrambling equipment can achieve basic conveying functions, its structural design has significant shortcomings in adaptability.
[0003] Specifically, due to the diverse specifications of medicine bottles, different models often have different bottle diameters. Existing automatic bottle unscramblers require adjustments to the width of their conveyor channels when switching between bottles of different diameters. However, current adjustment methods primarily rely on manual loosening of bolts, manual movement of guardrails, and then tightening – complex operations that sometimes require replacing specialized mechanical modules. This process is time-consuming and lacks precision, resulting in extremely low changeover efficiency on the production line and severely restricting the flexible production capabilities of pharmaceutical manufacturers. Furthermore, during high-speed bottle unscrambling, existing equipment often lacks efficient and automated rejection mechanisms for broken or defective bottles, easily leading to substandard products flowing downstream, causing production waste and potential product quality risks.
[0004] Therefore, this utility model proposes an automatic bottle unscrambler for the production and packaging of liquid medicines to overcome the shortcomings of the prior art. Utility Model Content
[0005] In view of the problems of existing automatic bottle unscramblers for liquid medicine production and packaging, such as the reliance on manual adjustment of the conveyor channel width, low efficiency, and difficulty in automatically adapting to different sizes of medicine bottles, this utility model aims to provide an automatic bottle unscrambler for liquid medicine production and packaging with an improved structure that can effectively solve the above problems.
[0006] This utility model provides an automatic bottle unscrambler for the production and packaging of liquid pharmaceuticals, including: a bottle unscrambler, a conveyor table, a motor, a rotating rod, gears, a rack, a transmission block, a transmission rod, and a conveying device.
[0007] The surface of the conveyor table is provided with a groove, and the transmission rod is slidably connected inside the groove. The top of the transmission rod is fixedly connected to a conveying device.
[0008] Furthermore, the motor, rotating rod, gear, rack, transmission block, and transmission rod are combined through a unique and specific connection method. Specifically: a motor is fixedly connected to one side of the conveyor platform; a rotating rod is fixedly connected to the output end of the motor; a gear is fixedly connected to the middle of the rotating rod; the rotating rod is rotatably connected to the interior of the conveyor platform via bearings; a rack is installed inside the conveyor platform, and the rack meshes with the gear; a transmission block is fixedly connected to one end of the rack, and the top of the transmission block is fixedly connected to the transmission rod.
[0009] The core solution utilizes the rotational motion of the motor to drive the gear to rotate, thereby causing the rack to move linearly and driving the transmission block and the transmission rod to move along the length of the chute to adjust the position of the conveying device, thus achieving the purpose of automatically adjusting the width of the conveying channel.
[0010] Preferably, the conveyor table has a guide groove inside, and a guide block is fixedly connected to the side of the rack away from the gear. The guide block is slidably connected inside the guide groove, and the guide block and the inner wall of the guide groove form a sliding fit. The cooperation between the guide block and the guide groove effectively limits the lateral displacement of the rack during movement, ensuring the accuracy of the transmission process.
[0011] Preferably, the conveyor table has a sliding cavity inside, the transmission block is located inside the sliding cavity, and a pulley is installed at the bottom of the transmission block. The pulley maintains rolling contact with the bottom inner wall of the sliding cavity. This structure uses a pulley to change the contact mode between the transmission block and the inner wall of the sliding cavity from sliding friction to rolling friction, which significantly reduces the operating resistance of the adjustment mechanism and makes the adjustment process easier and smoother.
[0012] Preferably, the surface of the conveyor table has multiple grooves arranged in parallel, and the number of transmission rods corresponds to the number of grooves. The conveying device is fixedly connected to the top of all the transmission rods. This multi-groove, multi-transmission-rod structure ensures the support strength and displacement synchronization of the conveying device throughout its width.
[0013] Preferably, a detector is fixedly installed on the inner wall of the conveying area of the bottle unloading device. The detector is located above the conveying table, and the detection end of the detector faces the conveying path of the conveying table. The detector can be a photoelectric sensor or an industrial camera to achieve real-time quality monitoring of the medicine bottles.
[0014] Preferably, a robotic arm is fixedly mounted on one end of the conveyor platform. The robotic arm is located downstream of the detector along the bottle conveying direction, and its gripping range covers the conveying path of the conveyor platform. The robotic arm is used to receive instructions and perform automatic rejection of defective bottles.
[0015] Preferably, a controller is fixedly installed on the top of the bottle unloading device, and the controller is electrically connected to both the detector and the robotic arm. The controller, as the information processing center, realizes the reception of detection signals, logical judgment, and the transmission of rejection instructions, forming a complete automated monitoring closed loop.
[0016] Preferably, the conveying device includes a conveying guardrail, which is fixedly connected to the transmission rod by bolts, and the conveying guardrail extends along the conveying direction of the conveying table.
[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a gear and rack transmission mechanism driven by a motor inside the conveyor table, the rotation of the gear drives the rack to move horizontally, and then drives the top conveying device to move along the slide along the chute through the transmission block and transmission rod. This solves the problem that existing bottle handling equipment requires manual adjustment or disassembly of conveying components when changing to different sizes of medicine bottles, which is cumbersome and inefficient. It achieves the technical effect of quickly and automatically adapting to medicine bottles of different diameters, simplifying the operation process, and significantly improving the changeover efficiency of the production line.
[0018] 2. In this utility model, by integrating a detector and a robotic arm in the bottle conveying area and controlling them together with a controller, the detector identifies damaged bottles in real time and controls the robotic arm to grab and remove them. This solves the problem in the prior art where damaged bottles are easily lost due to human error and flow into the subsequent packaging process, affecting product quality and production safety. It achieves the technical effect of fully automatic online quality monitoring, effective isolation of defective products, and ensuring product qualification rate. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0022] Example: Please refer to Figures 1 to 4 This utility model provides an automatic bottle unscrambler for the production and packaging of liquid medicines, which aims to solve the problems of cumbersome adjustment and inability to automatically adapt to the width of the conveying channel when faced with medicine bottles of different diameters and specifications in the prior art.
[0023] like Figure 1 As shown, the overall structure of the automatic bottle unscrambler for liquid medicine production and packaging includes a bottle unscrambler device 1 and a conveyor platform 2 installed inside the bottle unscrambler device 1. The bottle unscrambler device 1 serves as the external frame and storage container of the overall equipment, used to accommodate the medicine bottles to be processed and introduce them into the internal process. The conveyor platform 2 is located in the bottom center area of the bottle unscrambler device 1, used to carry and transport the medicine bottles to the next process. The surface of the conveyor platform 2 is provided with multiple grooves 12, which penetrate through the upper surface of the conveyor platform 2 and extend downward. A transmission rod 10 is slidably connected inside the grooves 12. The top of the transmission rod 10 extends out of the surface of the conveyor platform 2 and is fixedly connected to a conveying device 11. The specific structure of the conveying device 11 is a conveying guardrail or a conveyor belt support, used to directly contact both sides of the medicine bottle and limit the width of the conveying path of the medicine bottle.
[0024] For the core drive structure of variable diameter adjustment, such as Figure 2 and Figure 3As shown, a motor 3 is fixedly connected to one side of the outer wall of the conveyor table 2 by bolts. The motor 3 serves as the power source for the adjustment mechanism, providing rotational torque. A rotating rod 4 is fixedly connected to the end of the output shaft of the motor 3. The rotating rod 4 extends horizontally and penetrates into the interior of the conveyor table 2. A gear 5 is fixedly connected to the middle of the rotating rod 4 by a key. In order to ensure smooth rotation, the rotating rod 4 is rotatably connected to the internal structure of the conveyor table 2 through bearings. The axial direction of the rotating rod 4 is perpendicular to the conveying direction of the conveyor table 2. This ensures that the side-mounted layout of the motor 3 will not interfere with the normal conveying operation of the conveyor table 2.
[0025] In terms of transmission connection, the conveyor table 2 is equipped with a rack 6 that meshes with the gear 5. The rack 6 is placed horizontally and its tooth surface is tightly meshed with the gear 5. The rotational motion of the gear 5 is converted into the linear translational motion of the rack 6 through the meshing relationship. In order to limit the degree of freedom of movement of the rack 6 and prevent it from deflecting during movement, a guide groove 13 is provided inside the conveyor table 2 corresponding to the position of the rack 6. A guide block 7 is fixedly connected to the side surface of the rack 6 away from the gear 5. The guide block 7 is slidably embedded in the guide groove 13, and the outer wall of the guide block 7 is slidably engaged with the inner wall of the guide groove 13. The guide block 7 makes a linear reciprocating motion along the guide groove 13, thereby ensuring that the rack 6 always maintains a horizontal and stable displacement state.
[0026] Furthermore, the end of the rack 6 is fixedly connected to the transmission block 8 by screws or welding. The transmission block 8 serves as an intermediate connecting member to transmit horizontal thrust. A sliding cavity 14 is provided inside the conveying table 2 corresponding to the active area of the transmission block 8. The transmission block 8 is accommodated inside the sliding cavity 14. In order to reduce the frictional resistance during the movement, a pulley 9 is installed at the bottom of the transmission block 8. The pulley 9 makes rolling contact with the bottom inner wall of the sliding cavity 14, using rolling friction to replace sliding friction and reducing the load on the motor 3. The top of the transmission block 8 is fixedly connected to the bottom end of the aforementioned transmission rod 10, thereby forming a complete transmission chain from the motor 3 to the gear 5, and then through the rack 6 and the transmission block 8 to finally drive the transmission rod 10 and the conveying device 11 to move. When the motor 3 drives the gear 5 to rotate, it drives the rack 6, the transmission block 8 and the transmission rod 10 to move synchronously along the length direction of the slide groove 12, thereby accurately adjusting the lateral position of the conveying device 11 on the surface of the conveying table 2.
[0027] To further ensure the stability and smoothness of the transmission chain during the aforementioned diameter adjustment process, the core of the technical solution in this embodiment lies in the fact that the internal structure of the conveyor table 2 has been specially designed for limiting and reducing resistance in response to the movement trajectory of the rack 6 and the transmission block 8. The specific mating structure eliminates movement gaps and reduces mechanical wear.
[0028] Please refer to the following carefully. Figure 2 and Figure 3 The internal fitting structure will be described in detail below: Inside the conveyor table 2, a guide groove 13 is provided corresponding to the back of the rack 6. The guide groove 13 extends horizontally along the width of the conveyor table 2, and the cross-sectional shape of the guide groove 13 is designed to be rectangular or dovetail-shaped to provide a stable guiding reference. At the same time, a guide block 7 is fixedly connected to the side wall of the rack 6 away from the gear 5. The shape and size of the guide block 7 are adapted to the guide groove 13. The guide block 7 is slidably embedded in the guide groove 13, and a sliding fit is formed between the outer surface of the guide block 7 and the inner wall of the guide groove 13.
[0029] This guiding and engaging structure between the rack 6 and the conveyor table 2, when the motor 3 drives the rack 6 to move under force, utilizes the linear reciprocating motion of the guide block 7 in the guide groove 13 to effectively limit the degree of freedom of the rack 6 in the vertical and rotational directions, prevent the rack 6 from shifting or vibrating due to uneven force, and ensure that the rack 6 and the gear 5 always maintain a precise center distance meshing state, thereby ensuring the accuracy of displacement transmission.
[0030] In addition, for the moving environment of the transmission block 8, the conveyor table 2 has a sliding cavity 14 inside to accommodate the transmission block 8. The spatial size of the sliding cavity 14 is larger than the outer contour of the transmission block 8 to provide sufficient displacement space. In order to reduce the moving resistance, the bottom surface of the transmission block 8 is rotatably connected to a pulley 9 by a shaft pin. The pulley 9 is located between the transmission block 8 and the bottom wall of the sliding cavity 14, and the circumferential surface of the pulley 9 maintains rolling contact with the bottom inner wall of the sliding cavity 14.
[0031] In the actual adjustment process, the rolling friction of the pulley 9 is used to replace the sliding friction between the bottom surface of the transmission block 8 and the inner wall of the slide cavity 14, which can significantly reduce the driving load of the motor 3, making the movement of the transmission rod 10 and the conveying device 11 more convenient and smooth, and avoiding adjustment jamming due to excessive friction. In order to meet the stability requirements of long-distance conveying, the number of slide grooves 12 opened on the surface of the conveying table 2 is set to multiple, and the multiple slide grooves 12 are arranged in parallel. The number of transmission rods 10 corresponds one-to-one with the number of slide grooves 12. The conveying device 11 is fixedly connected to the top of all transmission rods 10 by bolts to achieve multi-point synchronous support and adjustment.
[0032] Based on the above embodiments regarding the variable diameter transmission and internal guide structure, this utility model also includes a preferred technical solution for quality monitoring and defective product rejection of medicine bottles, aiming to solve the problems of low efficiency of manual inspection and damaged bottles flowing into subsequent packaging stages.
[0033] As a preferred embodiment, in order to achieve real-time monitoring of the bottle's condition during transportation, please refer to the following: Figure 1 and Figure 4The internal conveying area of the bottle unscrambling device 1 is equipped with a detector 15. The detector 15 is fixedly installed on the inner wall of the bottle unscrambling device 1 by a bracket. The specific installation position of the detector 15 is above the conveying table 2, and the sensing probe or camera lens of the detector 15 faces the conveying path on the surface of the conveying table 2, which can cover every bottle flowing through the area. The detector 15 uses an industrial camera or photoelectric sensor to obtain the appearance integrity data of the bottle in a non-contact manner.
[0034] As another preferred embodiment, in order to cooperate with the detector 15 to achieve automatic removal of abnormal bottles, a robotic arm 16 is fixedly installed on one side of the conveyor 2. The robotic arm 16 is located downstream of the detector 15 along the bottle conveying direction in terms of spatial layout, and a certain buffer distance is maintained between the two for signal processing. The base of the robotic arm 16 is fixed to the side frame of the conveyor 2, and its active execution end extends above the conveying path of the conveyor 2. The gripping range or pushing range of the robotic arm 16 completely covers the effective conveying width of the conveyor 2, and can move the confirmed broken bottles laterally out of the conveying queue.
[0035] Furthermore, in order to construct a complete automated control closed loop, a controller 17 is fixedly connected to the top outer surface of the bottle handling device 1 by screws. The controller 17 integrates a microprocessor and a signal processing module. The controller 17 establishes an electrical connection with the detector 15 in the conveying area and the robotic arm 16 on the side of the conveying table 2 through wires. As the information processing center, the controller 17 receives the electrical signals fed back by the detector 15 and sends drive commands to the robotic arm 16, thereby realizing the linkage control from defect identification to physical rejection.
[0036] Working principle: First, the medicine bottles to be sorted are placed in the storage area of the bottle sorting device 1. The bottle sorting device 1 starts to run and transports the medicine bottles in an orderly manner to the internal conveyor platform 2. At this time, the conveying device 11 on the surface of the conveyor platform 2 receives the medicine bottles and smoothly transports them to the subsequent working area along the conveying path. During this process, the detector 15 located above the conveying path works continuously to monitor the appearance of each medicine bottle in real time.
[0037] If the detector 15 detects a damaged or non-compliant medicine bottle on the conveyor 2, the detector 15 immediately generates an abnormal electrical signal and sends it to the controller 17 at the top of the bottle unloading device 1. After receiving the signal and performing logical processing, the controller 17 quickly issues an execution command to the downstream robotic arm 16. The robotic arm 16 responds to the command and performs a grabbing or pushing action, accurately removing the damaged medicine bottle from the conveying path of the conveyor 2. This ensures that only qualified medicines flow into the next packaging process, effectively avoiding production line downtime or packaging quality problems caused by defective products.
[0038] When production needs change and medicine bottles of different diameters need to be sorted and packaged, there is no need to manually disassemble the equipment. The motor 3 fixed on the side wall of the conveyor 2 is started directly. The output end of the motor 3 drives the rotating rod 4 to rotate inside the conveyor 2. The gear 5 fixed in the middle of the rotating rod 4 rotates synchronously. Since the gear 5 and the rack 6 are in a meshing state, the rotational motion of the gear 5 is converted into the linear translational motion of the rack 6.
[0039] During the movement of rack 6, guide block 7, which is fixedly connected to it, slides linearly back and forth in guide groove 13 inside conveyor table 2. The limiting effect of guide groove 13 on guide block 7 effectively resists the lateral offset force that may be generated during gear 5 transmission, ensuring that rack 6 always moves smoothly in a horizontal straight line. At the same time, rack 6 drives transmission block 8 at the end to move synchronously in slide cavity 14. Pulley 9 at the bottom of transmission block 8 rolls on the bottom wall of slide cavity 14, greatly reducing frictional resistance during movement and making the adjustment process smoother.
[0040] As the transmission block 8 moves, the transmission rod 10 fixed to its top slides along the length of the slide groove 12 on the surface of the conveyor table 2. The transmission rod 10 then drives the top conveyor device 11 to move laterally. By controlling the forward or reverse rotation of the motor 3, the conveyor device 11 can be controlled to move inward or outward, thereby precisely adjusting the width of the conveying channel until the width matches the diameter of the medicine bottle to be produced, thus completing the automated diameter adjustment operation.
[0041] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
