Description

A conveying device Technical Field

[0001] This application relates to the field of product transportation technology, and in particular to a conveying device. Background Technology

[0002] For bottled products (such as bottled pharmaceuticals), during filling, a conveyor system moves the bottles to the filling position for filling, and after filling, they are moved to the conveyor position. The conveyor system needs to operate intermittently, meaning that the conveyor system drives the bottles to remain at a designated position for a sufficient amount of time to meet the filling and testing requirements of certain bottled products (such as pharmaceuticals).

[0003] In the prior art, the conveying device includes a drive assembly and a toothed plate. The drive assembly includes a cam, which is connected to the toothed plate. The toothed plate is connected to the bottle container. The cam causes the toothed plate to move in a rectangular motion trajectory, thereby driving the bottle container to move and thus realizing intermittent transportation.

[0004] However, the trajectory of the aforementioned drive components is determined by the shape of the cam, and the trajectory is relatively simple after the cam is machined. Summary of the Invention

The swing arm assembly includes a first swing arm, a second swing arm, a third swing arm, and a fourth swing arm that are sequentially hinged together. The first swing arm and the fourth swing arm are both connected to the drive mechanism. The hinged ends of the third swing arm and the second swing arm are connected to the conveying component. The drive mechanism is used to drive the first swing arm and the fourth swing arm to rotate, so as to drive the conveying component to reciprocate along a preset trajectory through the third swing arm and the second swing arm.

The transmission shaft is connected to a driving member, one gear is sleeved on the transmission shaft, and the other gear is sleeved on a rotating shaft. Both the transmission shaft and the gears are disposed within a mounting base.

[0013] In one possible implementation, the conveying device in this application embodiment further includes at least one anti-fall component, which is disposed on the rotating shaft and is used to support the corresponding gear.

[0014] In one possible implementation, the conveying device in this application embodiment includes at least two anti-fall components, which are respectively sleeved on two first rotating shafts and a second rotating shaft to support two gears respectively.

[0015] In one possible implementation, the conveying device in this application embodiment further includes at least one sealing component, which is used to seal the gap between the first rotating shaft and the second rotating shaft or to seal the gap between the first rotating shaft and the mounting base.

[0016] In one possible implementation, the conveying device in this application embodiment further includes at least one linkage member, and the number of drive mechanisms and swing arm assemblies is at least two. The two drive mechanisms and the two swing arm assemblies are spaced apart along the length direction of the conveying member. The drive mechanisms are connected between adjacent two swing arm assemblies through the linkage member so that the first swing arm and the fourth swing arm of the two swing arm assemblies rotate synchronously.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] It should be noted that in the description of the embodiments of this application, the terms "upper", "lower", "inner", "outer" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description, and are not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0037] Furthermore, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] For bottled products (such as bottled pharmaceuticals), during filling, a conveyor system moves the bottles to the filling position for filling, and after filling, they are moved to the conveyor position. The conveyor system needs to operate intermittently, meaning that the conveyor system drives the bottles to remain at a designated position for a sufficient amount of time to meet the filling and testing requirements of certain bottled products (such as pharmaceuticals).

[0040] In the prior art, the conveying device includes a drive assembly and a toothed plate. The drive assembly includes a cam, which is connected to the toothed plate. The toothed plate is connected to the bottle container. The cam causes the toothed plate to move in a rectangular motion trajectory, thereby driving the bottle container to move and thus realizing intermittent transportation.

[0041] However, the trajectory of the aforementioned drive components is determined by the shape of the cam, and once the cam is machined, its trajectory is relatively simple. If the cam's contour is fixed after machining, its trajectory cannot be changed, resulting in a fixed motion trajectory (such as the rectangular path of a toothed plate). This limited application scenarios, such as only being suitable for a single bottle type or a fixed production cycle, require replacing the cam and remachining, leading to low efficiency and increased costs.

[0042] In view of this, this application provides a conveying device, including: a drive mechanism; a conveying component; and a swing arm assembly. The swing arm assembly includes a first swing arm, a second swing arm, a third swing arm, and a fourth swing arm that are hinged sequentially. The first swing arm and the fourth swing arm are both connected to the drive mechanism. The hinged ends of the third swing arm and the second swing arm are connected to the conveying component. The drive mechanism is used to drive the first swing arm and / or the fourth swing arm to rotate, so as to drive the conveying component to reciprocate along a preset trajectory through the third swing arm and the second swing arm. The swing arm assembly of this application includes a first swing arm, a second swing arm, a third swing arm, and a fourth swing arm that are hinged sequentially to form a four-sided linkage hinge structure. The drive mechanism controls the rotation of the first and fourth swing arms, making both the first and fourth swing arms act as active arms, driving the second and third swing arms to move respectively. The second and third swing arms are superimposed and combined at their hinge ends, allowing for various complex and variable motion trajectories. Since these hinge ends are connected to the conveyor, they drive the movement of the conveyor. By adjusting the rotation of the first and fourth swing arms (such as rotation speed, rotation angle, rotation sequence, and rotation time) through the drive mechanism, the motion trajectory of the conveyor (such as rectangular, elliptical, or other shapes designed as needed) can be adjusted, thus achieving trajectory changes for the conveyor.

[0043] The present application will now be described in detail with reference to Figures 1 and 4 and specific embodiments.

[0044] This application provides a conveying device, including: a drive mechanism 100; a conveying component 200; and a swing arm assembly 300. The swing arm assembly 300 includes a first swing arm 310, a second swing arm 320, a third swing arm 330, and a fourth swing arm 340 that are hinged in sequence. The first swing arm 310 and the fourth swing arm 340 are both connected to the drive mechanism 100. The hinged ends of the third swing arm 330 and the second swing arm 320 are connected to the conveying component 200. The drive mechanism 100 is used to drive the first swing arm 310 and / or the fourth swing arm 340 to rotate, so as to drive the conveying component 200 to reciprocate along a preset trajectory through the third swing arm 330 and the second swing arm 320.

[0045] Both the first swing arm 310 and the fourth swing arm 340 have stepped connecting holes at one end, which are connected to the output shaft of the drive mechanism 100 via connecting parts. Rotation of the output shaft drives the first swing arm 310 and the fourth swing arm 340 to rotate. The connecting parts can be bolts or screws, and the connecting holes can be threaded holes or bolt holes; this application does not impose any limitations on these. The output shaft can be two rotating shafts 110, with the first swing arm 310 and the fourth swing arm 340 respectively connected to one of the two rotating shafts 110. Alternatively, the output shaft can be the output shaft of two drive units 130, with the first swing arm 310 and the fourth swing arm 340 respectively connected to the output shaft of one of the two drive units 130.

[0046] This application does not limit the hinge method of the first swing arm 310, the second swing arm 320, the third swing arm 330, and the fourth swing arm 340 in the swing arm assembly 300. For example, the first swing arm 310 has a bearing mounting hole at the end facing away from the drive mechanism 100, and the second swing arm 320 also has a bearing mounting hole facing the first swing arm 310. The bearing passes through the bearing mounting holes of the first swing arm 310 and the second swing arm 320, so that the first swing arm 310 and the second swing arm 320 are hinged. The hinge between the second swing arm 320 and the third swing arm 330, and the hinge between the third swing arm 330 and the fourth swing arm 340, can also be implemented in the above manner. It should be noted that the first swing arm 310 and the fourth swing arm 340 can both be machined linkage-type parts.

[0047] This application utilizes a swing arm assembly 300 comprising a first swing arm 310, a second swing arm 320, a third swing arm 330, and a fourth swing arm 340, which are sequentially hinged to form a four-sided linkage hinge structure. The drive mechanism 100 controls the rotational movement of the first swing arm 310 and the fourth swing arm 340, making both the first swing arm 310 and the fourth swing arm 340 act as active arms, respectively driving the second swing arm 320 and the third swing arm 330 to move. These arms are superimposed and combined at the hinge ends of the second swing arm 320 and the third swing arm 330, allowing for various complex and variable motion trajectories. Since these hinge ends are connected to the conveyor 200, they drive the movement of the conveyor 200. The drive mechanism 100 adjusts the rotational movement of the first swing arm 310 and the fourth swing arm 340 (such as rotational speed, rotational angle, rotational sequence, and rotational time), thereby adjusting the motion trajectory of the conveyor 200 (such as rectangular, elliptical, or other shapes designed as needed).

[0048] In some cases, the first swing arm 310 and the fourth swing arm 340 can be connected to the same drive mechanism 100. For example, the drive mechanism 100 is a single motor that drives the first swing arm 310 and the fourth swing arm 340 to rotate simultaneously through a gear set or a synchronous belt. For instance, if the first swing arm 310 and the fourth swing arm 340 have the same arm length and rotate synchronously in the same direction, the conveyor 200 can make a linear reciprocating motion. If the first swing arm 310 and the fourth swing arm 340 are not of equal length, the conveyor 200 can make an elliptical trajectory motion. Of course, the first swing arm 310 and the fourth swing arm 340 can also be connected to different drive mechanisms 100. For example, the first swing arm 310 and the fourth swing arm 340 can be connected to different drive mechanisms 100 respectively. The first swing arm 310 is driven by one motor, and the fourth swing arm 340 is driven by another motor, so that the speed, direction and phase of the first swing arm 310 and the fourth swing arm 340 are independently controllable. The motion trajectory of the hinge end of the second and third swing arms can be programmed in real time. For example, the first swing arm 310 and the fourth swing arm 340 can achieve linear or elliptical reciprocating motion driven by one motor when they are synchronized at the same speed. The first swing arm 310 and the fourth swing arm 340 can achieve asynchronous motion, such as one fast and one slow, so that the conveyor 200 can achieve figure-eight motion or custom trajectory motion. The first swing arm 310 and the fourth swing arm 340 can achieve stepped rectangular trajectory motion of the conveyor 200 when they rotate alternately.

[0049] Furthermore, in some cases, the drive mechanism 100 can simultaneously drive the first swing arm 310 and the fourth swing arm 340 to rotate. By adjusting the motion parameters of the first swing arm 310 and the fourth swing arm 340, arbitrary planar trajectories (such as star-shaped or wavy lines) can be synthesized. In some cases, the drive mechanism 100 can drive one of the first swing arm 310 and the fourth swing arm 340 to rotate, such as driving the first swing arm 310 to rotate or driving the fourth swing arm 340 to rotate. This is suitable for scenarios with light loads, short strokes, and low costs. For example, when driving the first swing arm 310, the trajectory of the conveyor 200 is approximately a short arc within a fan-shaped range. The drive mechanism 100 includes two rotating shafts 110 and a mounting base 120. The rotating shafts 110 are mounted on the mounting base 120 and rotate relative to the mounting base 120. The first swing arm 310 and the fourth swing arm 340 are respectively connected to the rotating shafts 110. The number of rotating shafts 110 can be two, with the two rotating shafts 110 arranged side by side, or the two rotating shafts 110 corresponding to the first rotating shaft 111 and the second rotating shaft 112 respectively.

[0050] Specifically, the mounting base 120 includes at least one mounting shaft seat and a base. The mounting shaft seat is disposed on the base, such as by bolts. The mounting shaft seat is a shaft-type part and is used to mount rotating shaft components 110. For example, there may be one mounting shaft seat, and two rotating shaft components 110 are connected in a sequential sleeve manner, with both rotating shaft components 110 rotating relative to the mounting shaft seat. Alternatively, there may be two mounting shaft seats, spaced apart on the base, with each mounting shaft corresponding to one of the two rotating shaft components 110.

[0051] In some embodiments, the pivot member 110 includes a first pivot 111 and a second pivot 112. The first pivot 111 is disposed on the mounting base 120 and is rotatably connected to the mounting base 120. The first pivot 111 is sleeved on the second pivot 112 and the second pivot 112 is rotatably connected to the first pivot 111. The first swing arm 310 is connected to the first pivot 111, and the fourth swing arm 340 is connected to the second pivot 112.

[0052] The rotating shaft component 110 also includes at least two rotating components 113. One rotating component 113 is disposed between the first rotating shaft 111 and the mounting base 120 to rotatably connect the first rotating shaft 111 and the mounting base 120. The other rotating component 113 is disposed between the first rotating shaft 111 and the second rotating shaft 112 to rotatably connect the second rotating shaft 112 and the first rotating shaft 111. The rotating component 113 may be a bearing 113.

[0053] Specifically, both ends of the mounting base 120 have bearing mounting steps for mounting bearings 113. Two bearings 113 are spaced apart axially along the first rotating shaft 111. The first rotating shaft 111 is inserted into the mounting base and rotatably connected to it via the two bearings 113. A shaft sealing ring is also provided on the mounting base, located between the mounting base and the first rotating shaft 111 to seal the connection gap between them. The shaft sealing ring can be fixed to the mounting base with bolts. The first rotating shaft 111 is sleeved on a second rotating shaft 112, which is rotatably connected to it. A bearing 113 is sleeved on the second rotating shaft 112, which is rotatably connected to the first rotating shaft 111 via the bearing 113. The number of bearings 113 mounted on the second rotating shaft 112 is not limited in this application. For example, the number of bearings 113 is at least one, and the number of bearings 113 can be two. The two bearings 113 are arranged axially spaced along the second rotating shaft 112. The inner wall of the first rotating shaft 111 has a bearing 113 mounting step for mounting the bearings 113.

[0054] The second rotating shaft 112 has a groove for installing a seal, such as an O-ring, to seal the second rotating shaft 112. The seal is located between the second rotating shaft 112 and the first rotating shaft 111 to seal the connection gap between the first rotating shaft 111 and the second rotating shaft 112.

[0055] In some embodiments, the drive mechanism 100 further includes two drive members 130, which drive the rotating shaft 110 to rotate. Each drive member 130 includes a motor 131 and a speed changer 132. The motor 131 is connected to the speed changer 132, the output shaft of the motor 131 is connected to the input shaft of the speed changer 132, and the output shaft of the speed changer 132 is connected to the rotating shaft 110 via a coupling 133. The output shaft of the speed changer 132 is directly connected to the rotating shaft 110. The speed changer 132 can be a speed reducer, and the motor 131 is a servo motor. This invention can also achieve repeatability and positioning accuracy through servo closed-loop control, eliminating mechanical backlash. For example, programmable acceleration / deceleration curves can reduce start-stop impact and support variable speed motion. Furthermore, the trajectory of the quadrilateral connecting rod end support point of the swing arm assembly 300 can be adjusted to adapt to workpieces of different shapes or sizes. Compared with traditional belt conveyors, this application is more flexible and suitable for complex path requirements.

[0056] In some embodiments, the drive mechanism 100 further includes two transmission assemblies 140, and the drive member 130 is connected to the rotating shaft member 110 through the transmission assemblies 140. The two drive members 130 are connected to the two transmission assemblies 140 in a one-to-one correspondence, and the two transmission assemblies 140 are connected to the two rotating shaft members 110 in a one-to-one correspondence.

[0057] In some embodiments, the transmission assembly 140 includes a transmission shaft 141 and at least two meshing gears 142. The transmission shaft 141 is connected to the drive member 130. One gear 142 is sleeved on the transmission shaft 141, and another gear 142 is sleeved on a rotating shaft member 110. Both the transmission shaft 141 and the gears 142 are disposed within the mounting base 120.

[0058] Both the first rotating shaft 111 and the second rotating shaft 112 are provided with keyways for connecting the gear 142 sleeved on them, so that the gear 142 drives the first rotating shaft 111 or the second rotating shaft 112 to rotate. In addition, the gear 142 can also be connected to the rotating shaft 110 through the spacer 143 and move synchronously with the rotating shaft 110.

[0059] For ease of description, the drive shaft 141 and at least two meshing gears 142 of the two transmission components 140 are respectively named as first drive shaft, first gear and second gear, second drive shaft, third gear and fourth gear. The first drive shaft and the second drive shaft are both mounted on the mounting base 120. The mounting base 120 also includes an upper base 123 and an intermediate mounting base 124. The upper base 123 is located on one side of the base 122. An installation cavity is formed between the intermediate mounting base 124 and the upper base 123. The two transmission components 140 are both located in the installation cavity. The first drive shaft and the second drive shaft are both connected to the upper base 123 and the intermediate mounting base 124. For example, the two ends of the first drive shaft are respectively connected to the upper base 123 and the intermediate mounting base 124. Mounting base 120 also includes a lower base 125, which is located below the intermediate mounting base 124 and connected by a support column 127. A drive mounting cavity is formed between the lower base 125 and the intermediate mounting base 124. The drive mounting cavity can be used to install couplings and reducers, or the drive mounting cavity can be used to install couplings. The side of the lower base 125 facing away from the intermediate mounting base 124 can be used for drive components, such as reducingrs and servo motors.

[0060] The first gear is mounted on the first transmission shaft, and the first gear meshes with the second gear. The second gear is mounted on the first rotating shaft 111, and the third gear is mounted on the second transmission shaft, meshing with the fourth gear. The fourth gear is mounted on the second rotating shaft 112. The diameter of the first gear is smaller than the diameter of the second gear, and the diameter of the third gear is smaller than the diameter of the fourth gear. This invention improves the response speed and accuracy of the transmission system by using two servo motors to drive the pinions, solving the problems of insufficient accuracy and slow response in traditional power transmission.

[0061] This application also incorporates a first rotating shaft 111 mounted on a second rotating shaft 112, with two large gears (such as the second and fourth gears) spaced axially. The staggered meshing phase of the two large gears counteracts part of the excitation force of the first and second rotating shafts as a whole, thereby enhancing structural stability, reducing vibration and noise, and improving the operational safety of the equipment. This solves the problems of structural instability and operational instability caused by improper fixing in traditional mechanisms. Furthermore, the large gears drive the active component of the four-bar linkage, achieving quadrilateral motion. This design makes the motion trajectory more stable and smooth, solving the problems of irregular and unstable motion that may occur when using traditional linkage mechanisms.

[0062] In some embodiments, at least one anti-fall component 400 is also included, which is disposed on the pivot 110 and is used to support the gear 142.

[0063] The anti-fall assembly 400 includes at least two anti-fall elements 410, which are respectively fitted onto the first rotating shaft 111 and the second rotating shaft 112 to support the gear 142 on the first rotating shaft 111 and the gear 142 on the second rotating shaft 112, respectively. One anti-fall element 410 can be a clamp, which is bolted to the first rotating shaft 111 to prevent the gear on the first rotating shaft 111 from falling. The other anti-fall element 410 can also be a clamp, which is bolted to the second rotating shaft 112 to prevent the gear on the right side plate of the drive clamp and the gear on the second rotating shaft 112 from falling. For example, the upper end face of the anti-fall element 410 abuts against the lower end face of the gear 142 (or the shoulder connected to the gear). When the gear 142 is subjected to downward gravity, equipment vibration, or axial impact force, the anti-fall element 410 provides an upward supporting reaction force to the gear 142 through its own mechanical strength and rigid connection with the rotating shaft, preventing it from sliding axially along the rotating shaft. It is understood that this application uses the anti-fall component 400 for axial positioning and locking, uses bolt preload to achieve a rigid fixed connection with the rotating shaft (such as the first rotating shaft 111 or the second rotating shaft 112), and directly supports the weight of the gear 142 through the physical contact surface.

[0064] In some embodiments, this application further includes a sealing component 500, which is used to seal the gap between the first rotating shaft 111 and the second rotating shaft 112 or to seal the gap between the first rotating shaft 111 and the mounting base 120.

[0065] For example, the sealing assembly 500 includes two seals 510. One seal 510 is disposed between the first rotating shaft 111 and the mounting base 120 to seal the gap between the first rotating shaft 111 and the mounting base 120. For example, the first rotating shaft 111 is inserted into the mounting shaft seat 121, and a groove is provided on the circumference of the first rotating shaft 111. The seal 510 is disposed in the groove to seal the gap between the first rotating shaft 111 and the mounting base 120, thereby sealing the first rotating shaft 111. The other seal 510 is disposed between the first rotating shaft 111 and the second rotating shaft 112 to seal the second rotating shaft 112. For example, the second rotating shaft 112 has a groove inside for mounting the other seal 510 of the second rotating shaft 112, and the shaft end face of the second rotating shaft 112 has an opening for connection to the first cantilever 310 by a fastener, which can be a bolt. Both seals 510 can be rotating shaft sealing rings, such as O-rings, and this application does not limit this. The sealing assembly 500 may further include a third seal 510, which cooperates with the seal 510 on the second rotating shaft 112 to achieve a sealing fit between the upper end faces of the first rotating shaft 111 and the second rotating shaft 112. This embodiment uses the sealing assembly 500 for sealing, ensuring operating conditions in a Class A environment.

[0066] This sealing design effectively prevents contaminants from entering, protecting the stability of the transmission system and the cleanliness of the working environment, solving common pollution and equipment damage problems in industries with extremely high environmental requirements, such as pharmaceuticals. A groove is provided at the mating clearance between the first shaft 111 and the mounting seat 121, and an O-ring (seal 510) is embedded therein. The O-ring uses its elastic deformation to fill the gap between the groove and the circumference of the shaft, forming a tight radial compression contact. At the connecting end face of the first shaft 111 and the second shaft 112, another O-ring is installed by creating a groove inside the second shaft 112. This seal is axially pressed between the mating end faces of the two shafts. When fasteners (such as bolts) lock the two shafts together, the O-ring is compressed and deformed, filling the microscopic unevenness of the end face mating and any possible assembly gaps, blocking the channels through which contaminants axially penetrate into the transmission system from the interface between the two shafts. Furthermore, the sealing assembly 500, the mounting shaft 121, and the two rotating shafts 110 form a sealing barrier, and the transmission assembly 140 is located below the mounting shaft 121 to avoid contamination.

[0067] In addition, this application also includes at least one linkage member 600, and the number of drive mechanisms 100 and swing arm assemblies 300 is at least two. The two drive mechanisms 100 and the two swing arm assemblies 300 are spaced apart along the length direction of the conveyor 200. The drive mechanisms 100 are connected to adjacent swing arm assemblies 300 through linkage members 600 so that the first swing arm 310 and the fourth swing arm 340 of the two swing arm assemblies 300 rotate synchronously.

[0068] For example, there are two linkage components 600, and the two linkage components 600 are respectively connected to the two rotating shaft components 110 in a one-to-one correspondence, so as to rotate synchronously with the first swing arm 310 and the fourth swing arm 340 respectively.

[0069] The linkage 600 includes a first link 610 and at least two second links 620. The two second links 620 are connected through the first link 610. One second link 620 is connected to a drive mechanism 100, and the other second link 620 is connected to another drive mechanism 100.

[0070] Specifically, each linkage 600 includes a first link 610 and at least two second links 620. The two ends of the first link 610 are respectively connected to the two second links 620 in a one-to-one correspondence (e.g., hinged). One second link 620 is connected to the first rotating shaft 111 or the second rotating shaft 112 of a drive mechanism 100, and the other second link 620 is also connected to the first rotating shaft 111 or the second rotating shaft 112 of the drive mechanism 100. Alternatively, each linkage 600 may only include the first link 610, with one end of the first link 610 connected to the first rotating shaft 111 or the second rotating shaft 112 of the drive mechanism 100, and the other end of the first link 610 also connected to the first rotating shaft 111 or the second rotating shaft 112 of the drive mechanism 100. The linkage of the two drive mechanisms 100 is achieved through the linkage component 600, so that the first swing arm 310 and the fourth swing arm 340 of the two swing arm assemblies 300 rotate synchronously, thereby synchronizing the movement trajectory of the conveyor 200. The conveyor 200 can be an output toothed plate, which can be matched with different tooth profiles according to different products. For example, the conveyor toothed plate can be matched with different tooth profiles according to the size of the vial and fixed to the hinge end by pins. Each linkage component 600 can be arranged at intervals along the direction of gravity. The first connecting rod can be the right side plate of the drive clamp plate, which is not limited in this application. The mounting base 120 may also include a table mounting plate 126, with the base 122 disposed on the table mounting plate 126. The conveyor 200 is located above one side of the table mounting plate 126, while the linkage component 600 is located on the other side of the table mounting plate 126. The conveyor 200 and the linkage component 600 are disposed on opposite sides of the table mounting plate 126. The extension direction of the table mounting plate 126 is parallel to the extension direction of the conveyor 200.

[0071] The linkage 600 synchronizes the motion between the two independent drive mechanisms 100, enabling the first swing arm 310 and the fourth swing arm 340 of the two swing arm assemblies 300 to rotate synchronously. In this embodiment, the intermittent conveying device has two independent drive mechanisms 100, each driving its own swing arm assembly 300 (including the first swing arm 310, the second swing arm 320, the third swing arm 330, and the fourth swing arm 340). The linkage 600 ensures that the conveying component 200 (such as the output toothed plate) moves along its length in a consistent trajectory without twisting. This requires the corresponding active arms (the first swing arm 310 and the fourth swing arm 340) of the two swing arm assemblies 300 to maintain the same rotation angle, speed, and direction. The linkage 600 is directly connected to the output shaft of the drive mechanism 100 (i.e., the first shaft 111 or the second shaft 112), and the output shaft is the shaft that drives the first swing arm 310 or the fourth swing arm 340 to rotate, so that the corresponding active arms (the first swing arm 310 and the fourth swing arm 340) in the two swing arm assemblies 300 move synchronously.

[0072] Of course, the conveying device of this application can also cooperate with the bottle-picking device. The conveying device can move back and forth, such as the conveying device carrying the conveyor 200 along a rectangular track. As the conveying device moves forward, the bottle-picking device can pick up the bottles on the conveyor 200. This application does not limit this. For example, during the movement of the conveying device along the rectangular track, at the position where bottles need to be picked up on its long side (i.e., the "forward movement" line segment), the conveying device can be stopped or kept at a constant speed to provide a stable bottle-picking window for the bottle-picking device. At corners, return sections, or movement sections where bottle picking is not required, the conveying device can move quickly. The bottle-picking device can be a clamp or a bottle unscrambler. This application does not limit this.
