[0056] Embodiment 1

[0057] like Figure 1 and Figure 2 As shown, the present application provides an automated production system for rapid bottle filling and capping, comprising a bottle feeding turntable 110, a bottle receiving turntable 170 and a main conveyor belt 100;

[0058] The main conveyor belt 100 is horizontally fixed between the bottle feeding turntable 110 and the bottle receiving turntable 170, and is used to transport the bottles from the bottle feeding turntable 110 to the bottle receiving turntable 170;

[0059] The bottle feeding turntable 110 and the bottle receiving turntable 170 are both rotatable disc-shaped operating platforms, each requiring an operator to operate. The bottle feeding turntable 110 is used to arrange and push empty bottle bodies onto the main conveyor belt 100, and the bottle receiving turntable 170 is used to centrally collect the finished bottle bodies after encapsulation and labeling.

[0060] On the main conveyor belt 100, in the direction from the bottle feeding turntable 110 to the bottle receiving turntable 170, there are successively arranged a double-head tracking filling machine 120, a cap hooking machine, a double-head tracking capping machine 140, and a vertical round bottle positioning labeling machine 160;

[0061] Among them, the double-head tracking capping machine 140 is used to tighten the bottle caps. The double-head tracking capping machine 140 includes a jaw assembly 200, a capping servo motor 142, a horizontal tracking servo motor 143, a lifting tracking servo motor 144, a pneumatic clamping device 145, and a servo lifting device 146;

[0062] A cap feeding and lifting machine is fixed on one side of the cap hooking machine;

[0063] Behind the main conveyor belt 100, there is an independent electric slide rail 150. The double-head tracking capping machine 140 is slidably connected to the slide rail. The double-head tracking capping machine 140 is located above the main conveyor belt 100, and tracks the bottle body through the horizontal tracking servo motor 143, the lifting tracking servo motor 144, and the servo lifting device 146, and adjusts its overall position relative to the bottle body on the main conveyor belt 100;

[0064] The jaw assembly 200 is a mechanical hand device that holds the bottle cap and drives it to rotate and tighten. It is vertically fixed below one side of the servo lifting device 146 and one side of the capping servo motor 142;

[0065] The capping servo motor 142 can control the rotation of the jaw assembly 200, and is used to provide rotational power for the jaw assembly 200 to screw the bottle cap;

[0066] After the bottle body is filled, the bottle body is conveyed to the cap hooking machine through the main conveyor belt 100. The cap hooking machine places the bottle cap on the bottle mouth. Then the conveyor belt continues to convey the bottle body to a position close to the double-head tracking capping machine 140. At this time, the horizontal tracking servo motor 143, the lifting tracking servo motor 144, and the servo lifting device 146 control the movement of the jaw assembly 200, so that it is located at the bottle cap and the jaws of the pneumatic clamping device 145 are on both sides of the bottle body to clamp the bottle body. The pneumatic clamping device 145 clamps and fixes the bottle body, and the jaw assembly 200 clamps the bottle cap and screws it.

[0067] The working process and principle in the above embodiments of the present application:

[0068] S1: Manually push the bottles into the bottle feeding turntable 110, and the bottle feeding turntable 110 automatically arranges the bottles and lets them flow into the conveyor belt;

[0069] S2: The empty bottles enter the double-head tracking filling machine 120 for filling;

[0070] S3: The cap sorting and lifting machine automatically sorts the caps in the correct direction and sends them into the track. The bottles enter below the cap hooking machine 130, and the cap hooking machine takes the bottle caps from the track and aligns and fastens the caps onto the bottle mouths;

[0071] S4: The double-head tracking capping machine 140 tightens the caps;

[0072] S5: The vertical round bottle positioning labeling machine 160 labels the bottles. Finally, the finished products enter the bottle receiving turntable 170;

[0073] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0074] In this embodiment, by setting the bottle feeding turntable 110, the bottle receiving turntable 170 and the main conveyor belt 100, and sequentially arranging a double-head tracking filling machine 120, a cap hooking machine, a double-head tracking capping machine 140 and a vertical round bottle positioning labeling machine 160 in the moving direction of the main conveyor belt 100, only two operators are required to place and retrieve the bottles respectively. The production capacity of this production system can reach 60 bottles per minute, it can quickly switch bottle types, has a wider filling range, can be compatible with filling volumes from 20 ml to 2000 ml, and can simultaneously achieve the advantages of precision, high speed, stability and convenient adjustment; thus solving the technical problem in the prior art that multiple people are required to cooperate in steps such as filling, capping and sealing, consuming a lot of labor; realizing the continuous automatic filling and sealing of the same product, reducing manual participation, and thus greatly improving the production efficiency.

[0075] Embodiment Two

[0076] Considering the clamping jaw assembly 200 in the first embodiment, when clamping the bottle cap, the resistance to screwing the cap increases with the degree of tightening as the bottle cap rotates with the thread, so a certain force change is required when clamping the bottle cap. In the prior art, a Chinese patent with authorization announcement number CN113371658B discloses a medicine bottle screwing machine, including a clamping arm for clamping and tightening the bottle cap, a rotating arm 220 is arranged on the upper part of the clamping arm, and the rotating arm 220 is arranged in a cylindrical shape. A gear ring 250 is arranged on the upper outer wall of the rotating arm 220, and the output gear 240 of the working end of the rotating motor is meshed with the gear ring 250. A plurality of claws 230 are arranged at the lower end of the rotating arm 220, and the claws 230 are hingedly arranged at the lower end of the rotating arm 220. A moving rod 210 is arranged in the rotating arm 220, and the moving rod 210 is arranged on the upper part of the rotating arm The end is fixed on the fixed frame of the capping machine, and the moving rod 210 moves relative to the moving rod 210 along the axial direction of the rotating arm 220. The lower end of the moving rod 210 is provided with a toggle mechanism for clamping / relaxing the toggle claw 230, and the toggle mechanism includes a toggle circle 400 and a toggle ring. The claw 230 is provided with a toggle circle 400, and the upper end of the claw 230 is fixedly connected to the outer edge of the toggle circle 400. The center of the toggle circle 400 is fixed to the lower end of the rotating arm 220. The toggle circle 400 rotates along the center to drive the claw 230 to open / close. The toggle circle 400 is provided with a fan-shaped groove in the direction of the moving rod 210, and the lower end of the moving rod 210 is provided with a toggle ring with a larger upper part and a smaller lower part. The large end of the toggle ring is embedded in the fan-shaped groove, and a gap is provided between the large end of the toggle ring and the fan-shaped groove. The clamping force of the clamping claw 230 can be increased as the bottle cap is continuously tightened. However, after the toggle ring in the above device contacts the upper stopper surface of the toggle ring 400, the toggle ring 400 moving downward is driven to rotate by the stationary toggle ring during the rotation of the rotating arm 220, so that the clamping claw 230 clamps the bottle cap; however, since the resistance is not large at the beginning during the tightening of the bottle cap, but only increases after several turns of twisting, in the process of the rotating arm 220 driving the clamping claw 230 to twist the bottle cap in the prior art, the clamping claw 230 is tightened inward too quickly, which may cause the bottle cap to be clamped by the clamping claw 230. 0. Deformation will occur after premature clamping, which may cause the thread of the bottle cap to be misaligned with the bottle mouth; secondly, in the prior art, when the claw 230 loosens the bottle cap, the angular velocity of the claw 230 loosening outward is the same as the angular velocity of the claw 230 clamping inward, and when the bottle cap is clamped by the claw 230, the rotating arm 220 will continue to rotate and tighten the bottle cap. Therefore, when the rotating arm 220 rotates in the opposite direction to loosen the bottle cap, the claw 230 may continue to be clamped for a certain period of time, which may cause the bottle cap to be loosened instead of being directly loosened. Therefore, it is necessary to improve the device, such as Figures 3 to 8 As shown, the specific structure is as follows:

[0077] The clamping jaw assembly 200 includes a rotating arm 220 arranged at the upper part, the rotating arm 220 is set to be cylindrical, a gear ring 250 is arranged on the upper outer wall of the rotating arm 220, the output gear 240 of the working end of the capping servo motor 142 is meshed with the gear ring 250, and a plurality of claws 230 are arranged at the lower end of the rotating arm 220; the claws 230 are rotatably connected to the lower end of the rotating arm 220, a moving rod 210 is arranged in the rotating arm 220, the upper end of the moving rod 210 is fixed to one side of the capping servo motor 142 through a horizontally arranged cross plate, the moving rod 210 moves relative to the moving rod 210 along the axial direction of the rotating arm 220, and a toggle mechanism for toggling the claw 230 is arranged at the lower end of the moving rod 210, the toggle mechanism includes a toggle circle 400 and a toggle ring, and the claw 230 is fixedly connected to the toggle circle 400;

[0078] The toggle ring 400 is an annular ring with an opening at one end, and the opening faces the moving rod 210. The toggle ring 400 is connected to the lower end of the rotating arm 220 via a plate 420. The plate 420 is a straight plate, one end of which is hinged to the lower end of the rotating arm 220 via a hinge shaft 410, and the other end is fixed to the lower edge of the opening of the toggle ring 400. The claw 230 is fixed to one end of the toggle ring 400, which is located on the side of the toggle ring 400 away from the moving rod 210 and is tangent to the circular surface of the toggle ring 400.

[0079] The upper edge of the opening of the dial ring 400 is in a pointed shape with an inclined end surface;

[0080] The cross section of the toggle ring is an oblique triangle, and the toggle ring as a whole is a rotating body formed by the oblique triangle rotating along the surface of the moving rod 210 and around the axis of the moving rod 210; Figure 8 , wherein the longest side of the oblique triangle becomes the upper surface of the toggle ring after rotation, and the upper surface is an upper inclined surface, the shortest side of the oblique triangle is vertically arranged and coincides with the outer surface of the moving rod 210, and the projection of a corner of the oblique triangle away from the moving rod 210 on the moving rod 210 is located on the vertical downward extension line of the shortest side of the oblique triangle; the angle between the shortest side and the longest side of the oblique triangle is 30 degrees to 45 degrees.

[0081] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0082] In this embodiment, a toggle ring with an oblique triangle cross section is provided, and the toggle ring 400 is provided in a ring shape, so that the upper end of the opening of the toggle ring 400 is in point contact with the upper inclined surface, so as to Figure 6, when the moving rod 210 moves upward relative to the rotating arm 220, the displacement h2 of the toggle ring is greater than the displacement h1 of the upper end of the toggle ring 400, so that in the process of the rotating arm 220 rotating to tighten the bottle cap, the clamping action of the claw 230 on the bottle cap is delayed relative to the twisting action of the claw 230 on the bottle cap, that is, the rotation angle β of the toggle ring 400 requires the length of the relative displacement h2 of the toggle ring. When the claw 230 needs to loosen the bottle cap, such as Figure 7 When the toggle ring starts to move downward relative to the toggle circle 400, the claw 230 will be loosened due to the lack of support from the toggle ring. When the edge of the toggle ring hits the abutment plate 420, the toggle circle 400 will rotate in the opposite direction at an angular velocity greater than that when clamped, thereby quickly loosening the bottle cap. That is, the toggle ring only needs to move downward by a length of h3 to make the toggle circle 400 rotate in the opposite direction by an angle of β, and the length of the displacement h3 required for this process is much smaller than h2.

[0083] The technical problem in the prior art that the bottle cap is easily unscrewed again when the clamping claw 230 reversely loosens the bottle cap is solved, and the clamping speed of the clamping claw 230 is slower than the loosening speed of the clamping claw 230, thereby reducing the risk of the bottle cap being unscrewed during the loosening process.

[0084] Embodiment 3

[0085] Considering that in the above-mentioned embodiment 2, during the process of the claw 230 loosening the bottle cap last time, the edge of the toggle ring hit the abutment plate 420 downward, thereby leaving a small gap between the upper inclined surface of the toggle ring and the toggle circle 400, when the claw 230 starts to rotate and the upper inclined surface touches the toggle circle 400 upward, the rotating arm 220 drives the claw 230 to rotate, but the claw 230 does not produce a tightening action during this period. When the upper inclined surface hits the toggle circle 400, the claw 230 starts to tighten inward, so the claw 230 rotates several times in vain, wasting a certain amount of time; therefore, the efficiency of the claw 230 in screwing the bottle cap has a certain room for improvement, so it is necessary to improve the device, such as Figures 9 to 13 As shown, the specific structure is as follows:

[0086] A circle of the inclined surface on the toggle ring is fixedly connected to an inclined plate 500 through a plurality of elastic members 510;

[0087] The elastic member 510 is an elastic connecting member that can be elastically extended and retracted. The extension direction of the elastic member 510 is perpendicular to the upper inclined surface. In this embodiment, it is preferably a compression spring.

[0088] The inclined plate 500 is a rotating body with a rectangular cross section and a rotation axis that is the axis of the moving rod 210. Figure 12The rectangular long side of the cross section of the inclined plate 500 is parallel to the longest side of the triangle of the cross section of the toggle ring, and the inclined plate 500 covers the upper inclined surface of the toggle ring.

[0089] The edge of the toggle ring is always in contact with the abutment plate 420; at the same time, the length of the elastic member 510 when not subjected to external force makes the end surface of the inclined plate 500 away from the upper inclined surface always close to the upper edge of the opening of the toggle ring 400; when the bottle cap is not clamped or the bottle cap is loosened, the elastic member 510 is at the maximum length, so that the inclined plate 500 can touch the upper end of the opening of the toggle ring 400, and the edge of the toggle ring can touch the abutment plate 420 at the same time.

[0090] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0091] This embodiment provides the inclined plate 500, so that after the clamping claw 230 releases the previous bottle cap, the inclined plate 500 automatically presses upward against the upper end surface of the opening of the dialing ring 400 driven by the elastic member 510, so that after the rotating arm 220 starts to rotate, the clamping claw 230 also starts to tighten synchronously, and at the same time, under the elastic support of the elastic member 510, when the clamping claw 230 starts to clamp, the clamping force of the clamping claw 230 on the bottle cap has a buffer margin, so that the clamping claw 230 will not directly squeeze and deform the bottle cap, and will not be too loose to turn the bottle cap. The technical problem of the time waste caused by the idling of the clamping claw 230 for several turns when screwing the bottle cap in the above-mentioned second embodiment is solved, and the clamping claw 230 can elastically clamp the bottle cap at the beginning, and the tightening and rotation of the clamping claw 230 start at the same time, thereby improving the technical effect of screwing the bottle cap.

[0092] Embodiment 4

[0093] Considering that the elastic member 510 in the third embodiment is fixed between the inclined plate 500 and the upper inclined surface of the toggle ring, when the toggle ring 400 moves, the position of the elastic member 510 changes relative to the force application point of the toggle ring 400 on the inclined plate 500, so the elastic member 510 is easily subjected to a force inclined to one side. Over time, the elastic member 510 is likely to drive the inclined plate 500 to tilt to one side, thereby making the reaction force of the inclined plate 500 on the toggle ring 400 uneven, and then there is a risk of causing the force angle of the claw 230 to deviate when tightening the cap, resulting in the risk of dislocation of the bottle cap thread, so the device needs to be improved, such as Figure 14 and Figure 15 As shown, the specific structure is as follows:

[0094] There are two elastic members 510, which are in a circular shape and made of elastic rubber, and have an arc-shaped cross section;

[0095] The inner circles of the two elastic members 510 are respectively fixed to the highest edge circle and the lowest edge circle of the upper inclined surface; the outer circle edges of the two elastic members 510 are respectively fixed to the upper edge circle and the lowest edge circle of the inclined plate 500 close to the upper inclined surface;

[0096] The elastic member 510, the inclined plate 500 and the upper inclined surface form a closed space, which is a sliding support cavity 800; the interior of the sliding support cavity 800 is filled with gas;

[0097] The sliding support cavity 800 is provided with a sac 600, which is a sac made of elastic material. The interior of the sac 600 is closed and filled with gas. The sac 600 is spherical when not subjected to external force and can slide in the sliding support cavity 800.

[0098] A magnetic ball 610 is disposed inside the bladder 600, and the magnetic ball 610 is a spherical permanent magnet;

[0099] A strong magnet 430 is fixedly embedded inside the open upper end of the toggle ring 400. The strong magnet 430 is a strong magnet. The toggle ring 400, the inclined plate 500 and the toggle ring are all made of non-magnetic materials, so that the strong magnet 430 can directly attract the magnetic ball 610 through magnetic force.

[0100] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0101] In this embodiment, the elastic member 510 is arranged as two upper and lower annular elastic rings, and a sliding support cavity 800 is formed between the inclined plate 500, the elastic member 510 and the toggle ring; a spherical sliding capsule 600 is arranged inside the sliding support cavity 800, and the interior of the sliding capsule 600 is filled with gas and a magnetic ball 610, and a strong magnet 430 is embedded in the toggle ring 400, and the strong magnet 430 is used to attract the magnetic ball 610 to slide in the sliding support cavity 800, and the gas in the sliding capsule 600 and its own elasticity are used to follow and support the position where the toggle ring 400 presses the inclined plate 500, thereby solving the technical problem that the elastic member 510 is prone to deflection due to uneven force, and achieving the technical effect of being able to actively follow the force application point of the toggle ring 400 for elastic support.

[0102] Embodiment 5

[0103] Considering that in the process of the inclined plate 500 in the fourth embodiment moving upward relative to the toggle ring 400, the force fed back by the toggle ring 400 to the inclined plate 500 through the claw 230 is continuously strengthened, so the pressure received by the sac 600 from the inclined plate 500 is also continuously strengthened. Since the elasticity of the sac 600 remains unchanged, the pressure on the bottle cap from the claw 230 increases linearly, that is, the increase rate of the pressure value received by the bottle cap will remain the same as the increase rate when the twisting starts. This process may cause the bottle cap or the sac 600 to be damaged due to excessive force due to excessive increase in force, so it is necessary to improve the device, such as Figures 16 to 20 As shown, the specific structure is as follows:

[0104] The end surface of the inclined plate 500 close to the toggle ring is covered and fixed with an inner convex plate 520, and the inner convex plate 520 is an arc-shaped rotating body with the middle portion bent in an upward slant direction;

[0105] There are four sliding sacs 600, and the four sliding sacs 600 are tightly fixed together along the four corners of a square on the same plane;

[0106] The four bursae 600 are externally coated with a covering bursa 700, and the covering bursa 700 is an elastic bursa body with a closed interior;

[0107] A magnetic ball 610 is disposed in each of the four bursae 600 .

[0108] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0109] In this embodiment, the end surface of the inclined plate 500 close to the toggle ring is covered and fixed with an inner convex plate 520. When the toggle ring moves upward at a uniform speed relative to the toggle ring 400, the sac 600 moves toward the lower end of the sliding support cavity 800 and the moving speed is kept uniform due to the attraction of the strong magnet 430. However, the distance between the inner convex plate 520 and the upper inclined surface gradually increases, so that the growth rate of the pressure value of the toggle ring 400 on the inclined plate 500 is slowed down, that is, during the process of the claw 230 screwing the bottle cap, the force increases more and more slowly, so that the sac 600 will not be subjected to excessive force before the bottle cap is tightened, so that the sac 600 is protected to a certain extent, thereby optimizing the service life of the device.

[0110] By combining and fixing the four sliding sacs 600 and arranging them in the covering sac 700, the supporting area of ​​the inclined plate 500 is larger, and the force on a single sliding sac 600 is smaller. At the same time, the magnetic balls 610 in four directions are attracted together, and the magnetic force is stronger and more stable. When the toggle ring 400 squeezes the inclined plate 500 with a greater force, the covering sac 700 can still stably maintain the corresponding position with the strong magnet 430 to support the inclined plate 500.

[0111] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
