Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and specifically relates to a filling and sealing packaging equipment applied to a rotary table. Background Art

[0002] During the high-speed start and stop stages of traditional rotary filling equipment, the liquid in the container is prone to violent shaking due to the inertia of the container. Especially for volatile or foaming liquids (such as alcohol, carbonated beverages, cosmetics, etc.), the imbalance of the liquid surface tension will cause a large amount of foam to be generated and even burst with a small amount of splashing, resulting in a decrease in packaging accuracy and sealing failure; most of the existing technologies inhibit the shaking by reducing the rotation speed of the turntable or increasing the mechanical clamping strength, but the former sacrifices production efficiency, and the latter is prone to cause deformation or damage of the container due to rigid clamping; in addition, it is difficult to balance the liquid level stability and the start-stop inertia compensation in conventional vertical filling. Especially during the acceleration and deceleration stages of the turntable, the difference in the inertial direction of the liquid causes the failure of a single tilting strategy and cannot achieve dynamic attitude adaptation, ultimately affecting the sealing performance of the seal and the packaging yield. Summary of the Invention

[0003] An embodiment of the present application provides a filling and sealing packaging equipment applied to a rotary table, and the main purpose is to reduce the generation of bubbles in the solution in the container during the acceleration and deceleration stages of the turntable.

[0004] To achieve the above object, an embodiment of the present application provides a filling and sealing packaging equipment applied to a rotary table, including a packaging bin, and further including:

[0009] An outer lid supply device located behind the inner lid supply device, and the outer lid supply device corresponds to the capping station of the rotary table;

[0010] Wherein, the container rotates through the steering adsorption assembly and is arranged in the arc chamfer of the clamping position in an inclined state. When the rotary table is at the moment of rotation or stop, the inclination directions of the containers located at the filling station or the buckling station are opposite.

[0011] In a feasible implementation, the following components are provided on the rotating table: An elastic reset support part is fixedly connected to the inner side and the arc chamfer of the rotating table, and can contact the outer wall of the container to drive the container to maintain an upright state; An air storage tank is arranged in the middle of the rotating table. The air storage tank is in a negative pressure state and is connected to all the steering adsorption components; A rotary power mechanism is fixedly installed below the rotating table. The driving end of the rotary power mechanism is connected to the rotating table to drive the rotating table to rotate horizontally; A negative pressure air pump is connected to the air storage tank; A side friction mechanism is arranged on the outer side of the rotating table, and the side friction mechanism can contact the outer wall of the lower half of the container.

[0012] In a feasible implementation, the following components are further connected to the rotating table: The top end face of the support table has an arc-shaped plane and is arranged at the bottom edge of the rotating table to support the bottom of the container during the rotating transportation process; A limiting strip is arranged at the top end of the support table. The limiting strip is arc-shaped and is located between the input device and the output device to mechanically trigger the closing of the steering adsorption component in the non-working area.

[0013] In a feasible implementation, the steering adsorption component includes: One end of a plurality of air path connecting pipes is connected to the air storage tank, and the other end extends to the middle position of the clamping position; A suction nozzle is rotatably arranged at the middle position of the inner wall of the clamping position, and the suction nozzle is connected to the air path connecting pipe; A switch is sleeved on the air path connecting pipe. The switch is a push-button switch, and the switch is default to the popped-up open state.

[0014] In a feasible implementation, the elastic reset support part includes an elastic air column. One end of the elastic air column is fixedly connected to the end face of the arc chamfer. The elastic air column is perpendicular to the side wall of the container, and the end of the elastic air column close to the container is made of a flexible sealing material.

[0015] In a feasible implementation, the elastic air column is connected to a positive pressure air storage structure, and the positive pressure air storage structure includes: An upper annular container is fixedly arranged on the upper half of the inner cavity of the rotating table; A lower annular container is fixedly arranged on the lower half of the inner cavity of the rotating table and is connected to the upper annular container; A plurality of convex parts are arranged in groups of two, and are respectively fixedly arranged on the outer walls of the upper annular container and the lower annular container along the circumferential direction. Each group of convex parts is connected to the elastic air column.

[0016] In a feasible implementation, the edge friction mechanism includes: an interception frame fixedly arranged outside the rotating table. The side wall of the interception frame on the side facing the clamping position is arc-shaped and concentric with the rotating table. A rotary belt is rotatably arranged in the arc-shaped inner cavity of the interception frame, and the side wall of the rotary belt is attached to the inner wall of the inner cavity of the interception frame. A friction strip passes through a strip-shaped through hole in the side wall of the interception frame and protrudes from the outer wall of the interception frame, and can contact the outer wall of the lower half of the container and can contact the outer wall of the lower half of the container.

[0017] In a feasible implementation, a plurality of inertial suspension members are equidistantly arranged at the bottom end of the friction strip. The inertial suspension members and the rotary belt are connected by a flexible connecting rope. The lower half of the inertial suspension member is a counterweight block for providing the inertial rotation effect of the rotary belt.

[0018] In a feasible implementation, a plurality of arc-shaped concentric grooves are arranged at the bottom end of the rotating table. The switch is located in the groove, and the groove is aligned with the position of the limiting strip.

[0019] A filling and sealing packaging device applied to a rotating table provided by the present application, through the combined action of the arc chamfers at the four corners of the clamping position of the rotating table and the steering adsorption, controls the container to lean forward along the acceleration direction of the turntable and lean backward along the deceleration direction at the filling and capping stations respectively, and uses the two-way tilting strategy to offset the liquid inertial impact in different stages, so that the liquid surface is always in the stable region of surface tension, effectively suppressing the generation of foam and the splashing of liquid droplets. The arc chamfer provides a flexible guiding space, combined with the negative pressure adsorption of the container middle part by the steering adsorption component, to achieve accurate controllability of the tilting posture and no rigid friction damage. The dynamic reverse tilting mechanism at the start and stop stages of the turntable, combined with the buffer compensation of the elastic reset support part, ensures the smooth switching of the container posture under high-speed operation, and significantly reduces the amplitude of the liquid surface fluctuation, thereby improving the sealing qualification rate and the comprehensive efficiency of the equipment for filling high-volatile liquids, foaming liquids or other special materials.

[0032] Please refer to Figures 1 to 9 As shown, the embodiment of the present application provides a filling and sealing packaging device applied to a rotary table, including a packaging bin 10, and further including: an input device 20, a rotary table 30, a filling station 40, an inner lid supply device 50, an outer lid supply device 60, and a container 80;

[0033] Specifically, the input device 20 is used to input the container 80 to be packaged into the packaging bin 10; the rotary table 30 is rotatably arranged in the packaging bin 10, and a plurality of clamping positions 31 capable of clamping the container 80 are arranged on the rotary table 30. Arc chamfers 33 are provided on the upper left and right sides and the lower left and right sides of the clamping position 31, and a steering adsorption assembly 32 is arranged in the middle of the clamping position 31; the filling station 40 is located at the rear side of the conveying direction of the input device 20 and corresponds to the filling station 40 of the rotary table 30; the inner lid supply device 50 is located at the rear side of the filling station 40, and the inner lid supply device 50 corresponds to the crimping station 51 of the rotary table 30; the outer lid supply device 60 is located at the rear side of the inner lid supply device 50, and the outer lid supply device 60 corresponds to the capping station 61 of the rotary table 30; wherein, the container 80 rotates through the steering adsorption assembly 32 and is arranged in the arc chamfer 33 of the clamping position 31 in an inclined state. When the rotary table 30 is at the moment of rotation or stop, the inclination directions of the containers 80 located at the filling station 40 or the crimping station 51 are opposite.

[0034] The present application provides a filling and sealing packaging device applied to a rotary table. A rotary table 30 is provided in a packaging bin 10 of the device. A plurality of clamping positions 31 with arc chamfers 33 at four corners are arranged circumferentially on the rotary table 30. A steering adsorption assembly 32 is configured in the middle of each clamping position 31 to tilt and rotate the container 80 by sucking the middle position of the container 80 through negative pressure. The input device 20 continuously conveys the container 80 to the starting station of the rotary table 30. When the rotary table 30 rotates, the clamping position 31 makes the container 80 generate a first tilt angle (10-15°) posture at the filling station 40, and the liquid surface is stabilized by the surface tension of the liquid. When the rotary table 30 rotates instantaneously, the container 80 tilts reversely to form a dynamic balance. After the filling is completed and the container rotates to the inner cover pressing station 51, the steering adsorption assembly 32 makes the container 80 generate a reverse tilt angle (10-15°) posture. Similarly, the liquid surface is stabilized by the surface tension of the liquid. When the rotary table 30 rotates instantaneously, the container 80 tilts reversely to form a dynamic balance. However, the tilt direction is opposite to the previous one to correspond to the two states of the starting acceleration state and the deceleration stop state of the rotary table 30. Subsequently, at the capping station 61, the outer cover is supplied by the outer cover supply device 60 of the outer cover and screwed to complete the sealing. Therefore, the present application adopts the structure of the rotary table 30, and the inertial compensation in the starting and stopping stages is realized by the cooperation of double-station reverse tilting. The container 80 tilts forward during the acceleration stage and tilts backward during the deceleration stage, effectively suppressing the liquid sloshing. The buffer guiding structure with the arc chamfer 33 provides the tilting space and flexible clamping for the container 80, thereby effectively avoiding the filling of liquid materials that are prone to generate foam and the situation of tiny liquid splashing caused by the bursting and defoaming of the foam, thereby enhancing the packaging and sealing effect of the device.

[0035] As Figures 1 to 9 shown, in some examples, further, the rotary table 30 is provided with: an elastic reset support portion, an air storage tank 35, a side friction mechanism 36, a rotary power mechanism 37, and a negative pressure air pump 38. The elastic reset support portion is fixedly connected to the inner side of the rotary table 30 and within the arc chamfer 33, and can contact the outer wall of the container 80 to drive the container 80 to maintain an upright state. The air storage tank 35 is arranged in the middle of the rotary table 30. The air storage tank 35 is in a negative pressure state and is connected to all the steering adsorption assemblies 32. The rotary power mechanism 37 is fixedly arranged below the rotary table 30. The driving end of the rotary power mechanism 37 is connected to the rotary table 30 to drive the rotary table 30 to rotate horizontally. The negative pressure air pump 38 is connected to the air storage tank 35. The side friction mechanism 36 is arranged on the outer side of the rotary table 30, and the side friction mechanism 36 can contact the outer wall of the lower half of the container 80.

[0036] In this embodiment, the additionally provided elastic reset support part of the rotary table 30 forms a flexible abutment with the outer wall of the container 80 through the elastic contact surfaces at its inner side and the arc chamfer 33; the edge friction mechanism 36 contacts the outer wall of the lower half of the container 80, and when the rotary table 30 rotates, it promotes the inclination of the container 80 through the combined action of the frictional resistance and the steering adsorption assembly 32. When the rotary table 30 starts to accelerate, the edge friction mechanism 36 exerts a lateral resistance on the container 80, and the steering adsorption assembly 32 adsorbs the middle part of the container 80 and drives it to lean forward, so that the container 80 deflects to the support area of the arc chamfer 33; when the rotary table 30 decelerates and stops, the edge friction mechanism 36 blocks in the reverse direction, and the steering adsorption assembly 32 makes the container 80 lean backward; the elastic reset support part assists the container 80 to maintain the upright reference position during the filling and inner cap buckling processes, and provides buffering through the flexible contact between the arc chamfer 33 and the outer wall of the container 80 during the inclination process. When the rotary power mechanism 37 drives the rotary table 30 to horizontally rotate, the dynamic cooperation between the steering adsorption assembly 32 and the edge friction mechanism 36 realizes the switching of the inclination direction of the container 80, and by adjusting the balanced posture, the liquid disturbance is reduced.

[0037] As Figure 3 and Figure 9 shown, in some examples, further, the rotary table 30 is further connected with: a support table 39 and a limit strip 391. The top end surface of the support table 39 has an arc-shaped plane and is arranged at the bottom edge of the rotary table 30 for supporting the bottom of the container 80 during the rotational transportation process; the limit strip 391 is arranged on the top end of the support table 39. The limit strip 391 is arc-shaped and is located between the input device 20 and the output device 70 for mechanically triggering the steering adsorption assembly 32 to close when it is in the non-working area.

[0038] In this embodiment, the support table 39 provides a continuous supporting surface for the bottom of the container 80 through the arc-shaped plane at the bottom edge. Its arc-shaped end face is located between the crimping station 51 and the input device 20. During crimping, screwing the outer cover, inputting and outputting the container 80, it is necessary to support the container 80. During a working interval when the container 80 performs a tilting action, that is, between the filling station 40 and the crimping station 51, the bottom end of the container 80 does not need to be supported to provide enough space at the bottom end of the container 80 for the container 80 to perform a fine-angle tilting turn; the arc-shaped trajectory of the limiting strip 391 is arranged coaxially with the rotation path of the rotating table 30. When the container 80 clamped is moved to the non-working section between the input device 20 and the output device 70, the limiting strip 391 forcibly closes the control valve switch 323 of the steering adsorption assembly 32 through mechanical physical contact pressure, turning off the negative pressure adsorption function, so that the container 80 turns off the adsorption function in the non-operation area to reduce energy consumption and noise; at the same time, before entering the output device 70, the steering adsorption assembly 32 rotates with the rotating table 30 into the position where the limiting strip 391 is located, and automatically turns off the adsorption after contacting the limiting strip 391, so that the container 80 that has completed packaging can easily break away from the adsorption and be sent out from the output device 70.

[0039] As Figure 2 , Figure 7 and Figure 8 shown, in some examples, furthermore, the steering adsorption assembly 32 includes: a plurality of air path connecting pipes 321, a suction nozzle 322, and a switch 323. One end of each of the plurality of air path connecting pipes 321 is connected to the air storage tank 35, and the other end extends to the middle position of the clamping position 31; the suction nozzle 322 is rotatably arranged at the middle position of the inner wall of the clamping position 31, and the suction nozzle 322 is connected to the air path connecting pipe 321; the switch 323 is sleeved on the air path connecting pipe 321, the switch 323 is a push-button switch 323, and the switch 323 is default to the pop-up open state.

[0040] In this embodiment, the air path connecting pipe 321 of the turning adsorption assembly 32 is distributed radially along the rotary table 30, transmitting the negative pressure of the air storage tank 35 to the suction nozzle 322 in the middle of each clamping position 31. The suction nozzle 322 rotates through a rotating shaft structure to further enable the suction nozzle 322 to tilt and rotate following the container 80, and synchronously maintain the positioning effect of the container 80. When the container 80 enters the clamping position 31, the negative pressure adsorption takes effect when the outer wall thereof contacts the suction nozzle 322, and the suction nozzle 322 rotates following the force state of the container 80. In the non-working area, the arc-shaped protrusion of the limit strip 391 mechanically pushes the reset rod of the switch 323, forcing the switch 323 to switch to the closed state to disconnect the air path between the air path connecting pipe 321 and the air storage tank 35. When the rotary table 30 rotates to the position of the input device 20, the suction nozzle 322 is out of the action range of the limit strip 391, and the switch 323 automatically pops up to restore the negative pressure adsorption. At this time, the suction nozzle 322 closely adheres to the outer wall of the middle part of the container 80 under the action of the negative pressure of the air path connecting pipe 321. Therefore, in this example, the adsorption effect can be started and stopped at an appropriate time through the mechanical triggering mechanism of the switch 323, and the start and stop timing is adapted to the switching process of the working stations.

[0041] As Figure 2 and Figure 7 shown, in some examples, furthermore, the elastic reset support part includes an elastic air column 34. One end of the elastic air column 34 is fixedly connected to the end face of the arc chamfer 33. The elastic air column 34 is perpendicular to the side wall of the container 80, and the end of the elastic air column 34 close to the container 80 is made of a flexible sealing material.

[0042] In this embodiment, the elastic air columns 34 are circumferentially distributed evenly along the end face of the arc chamfer 33 of the clamping position 31. Its fixed end is fixedly connected to the rotary table 30, and the free end uses a hemispherical silica gel sealing head to vertically contact the side wall of the container 80. When the turning adsorption assembly 32 adsorbs the middle part of the container 80 through the suction nozzle 322 and drives it to tilt, the elastic air column 34 is compressed and deformed under the action of the lateral pressure of the container 80, and the gas inside it generates buffer damping through the sealed flexible cavity, and at the same time stores elastic reset potential energy. When in the processing station that needs to be executed, the elastic restoring force of the elastic air column 34 pushes the container 80 to restore the upright state. At this time, the vertical contact surface between the flexible sealing head and the outer wall of the container 80 forms a non-slip static friction to prevent the container 80 from shaking during the upright reset process. Therefore, the setting of this example enables the container 80 to always have a tendency to restore the upright state through the setting of the elastic air column 34 during the rotation of the rotary table 30. After the external force on the container 80 is removed, it can be in an upright working state.

[0043] As Figure 7As shown, in some examples, further, the elastic air column 34 is connected to a positive-pressure gas storage structure, which includes: an upper annular container 341, a lower annular container 342, and a plurality of convex parts 343. The upper annular container 341 is fixedly arranged on the upper half of the inner cavity of the rotating table 30; the lower annular container 342 is fixedly arranged on the lower half of the inner cavity of the rotating table 30 and is connected to the upper annular container 341; every two of the plurality of convex parts 343 are in a group and are respectively fixedly arranged on the outer walls of the upper annular container 341 and the lower annular container 342 along the circumferential direction, and each group of convex parts 343 is connected to the elastic air column 34.

[0044] In this embodiment, the positive-pressure gas storage structure forms an annular gas cavity through the coaxial nesting of the upper annular container 80 and the lower annular container 80, wherein the convex parts 343 of the upper annular container 341 and the corresponding convex parts 343 of the lower annular container 342 form a further pressure transmission channel; the fixed ends of the elastic air columns 34 are respectively fixedly connected to the convex parts 343 on the outer walls of the upper annular container 80 and the lower annular container 80, so that the gas in the annular gas cavity in the positive-pressure state can be evenly conducted into each elastic air column 34; when the container 80 is tilted by the edge friction mechanism 36, elastic and non-destructive support can be formed through the elastic air columns 34; during the stationary stage of the rotating table 30, the positive-pressure gas in the upper annular container 80 and the lower annular container 80 drives each elastic air column 34 to stretch and reset through the convex parts 343, forcing the container 80 to return to the upright state.

[0045] As Figures 3 to 6 As shown, in some examples, further, the edge friction mechanism 36 includes: an intercepting frame 361, a rotating belt 362, and a friction strip 363. The intercepting frame 361 is fixedly arranged on the outside of the rotating table 30. The side wall of the intercepting frame 361 facing the clamping position 31 is arc-shaped and is concentric with the rotating table 30; the rotating belt 362 is rotatably arranged in the arc-shaped inner cavity of the intercepting frame 361, and the side wall of the rotating belt 362 is attached to the inner wall of the inner cavity of the intercepting frame 361; the friction strip 363 passes through the strip-shaped through hole on the side wall of the intercepting frame 361 and protrudes from the outer wall of the intercepting frame 361 and can contact the outer wall of the lower half of the container 80 and can contact the outer wall of the lower half of the container 80.

[0046] In this embodiment, the intercepting frame 361 of the edge friction mechanism 36 forms a guiding track through its arc-shaped side wall concentric with the rotating table 30, and the rotary belt 362 can rotate synchronously along the rotating direction of the rotating table 30 in the inner cavity of the intercepting frame 361; the friction strips 363 protrude 3-5 mm from the outer wall of the intercepting frame 361 through strip-shaped through holes, and the exposed surface of the friction strips 363 is in continuous frictional contact with the outer wall of the lower half of the container 80; when the rotating table 30 rotates, the container 80 in the clamping position 31 rotates synchronously with the turntable, and the outer wall of the lower half of the container 80 contacts the friction strips 363; since the friction strips 363 are slidably connected to the inner cavity of the intercepting frame 361 through the rotary belt 362, the rotation of the rotary belt 362 lags slightly behind the rotating table 30, resulting in the friction strips 363 applying a radial frictional force to the container 80, forcing the nozzle 322 in the middle of the container 80 to deflect; during the acceleration stage of the rotating table 30, the friction strips 363 force the container 80 to lean forward in the rotating direction through the contact pressure, and during the deceleration stage, they force the container 80 to lean backward in the rotating direction of the rotating table 30. Compared with the prior art, the container 80 does not need to move and stop repeatedly, and at the same time, the disturbance effect between the solution and the container 80 and the relative shaking between the container 80 and the solution are reduced, and the possibility of foam generation is reduced.

[0047] As Figures 4 to 6 shown, in some examples, further, a plurality of inertial suspension members 364 are equidistantly arranged at the bottom end of the friction strips 363. The inertial suspension members 364 and the rotary belt 362 are connected by flexible connecting ropes. The lower half of the inertial suspension members 364 is a counterweight block, which is used to provide the inertial rotation effect of the rotary belt 362.

[0048] In this embodiment, the inertial suspension members 364 and the rotary belt 362 form a dynamic coupling mechanism through flexible connecting ropes. When the rotating table 30 accelerates and rotates, the counterweight block generates a lag displacement due to gravity, and applies a pulling force to the rotary belt 362 through the connecting rope, causing a relative displacement in the contact between the friction strips 363 and the outer wall of the container 80, forcing the container 80 to rotate and lean forward; when the rotating table 30 decelerates, when the rotating table 30 decelerates to a stop, the counterweight block lags behind the rotating table 30 to stop due to inertia, and applies a pulling force to the rotary belt 362 through the connecting rope, causing a relative displacement in the opposite direction in the contact between the friction strips 363 that continue to rotate and the outer wall of the container 80, forcing the container 80 to rotate in the opposite direction and lean backward; preventing the solution inside the container 80 from overflowing due to moving inertia, and at the same time reducing the disturbance between the solution and the container 80 and reducing the amount of foam generated.

[0049] In some examples, furthermore, in order to further achieve a more precise and adjustable anti-disturbance effect for the container 80 on the turntable 30, in this example, the counterweight is replaceably arranged. According to different counterweight weights, the difficulty of the container 80 driving the friction strip 363 equipped with different weights of counterweights to rotate is different. For example, the friction strip 363 and the rotary belt 362 equipped with lighter counterweights are easier to follow the rotation of the turntable 30, and vice versa. Therefore, the inclination angle of the container 80 also has a related proportional change. Furthermore, the positive pressure gas storage structure is also provided with a gas supply inlet, a pressure gauge is arranged inside the positive pressure gas storage structure, and the air pressure inside the elastic air column 34 is adjusted through the gas supply inlet, so that the air pressure inside the elastic air column 34 can also be adjusted as needed. When the pressure increases, the rotation difficulty of the container 80 will also increase. Therefore, the gas pressure inside the positive pressure gas storage structure can be adjusted to synchronously adjust the inclination angle of the container 80 during the station switching.

[0050] As Figure 4 and Figure 5 shown, in some examples, furthermore, a plurality of arc-shaped concentric grooves 301 are provided at the bottom end of the turntable 30, the switch 323 is located inside the groove 301, and the position of the groove 301 is aligned with the limiting strip 391.

[0051] In this embodiment, the arc-shaped concentric grooves 301 at the bottom end of the turntable 30 are equally angularly distributed along the rotation axis of the turntable 30; the switch 323 is embedded in the inner cavity of the groove 301, and its pressing contact point is flush with the opening plane of the groove 301. When the turntable 30 rotates to the position of the limiting strip 391, the arc-shaped convex part of the limiting strip 391 just inserts into the groove 301 and presses down the contact point of the switch 323 to achieve mechanical triggering. The suction nozzle 322 at the current position will not suck air. When the turntable 30 continues to rotate, the groove 301 gets out of the action range of the limiting strip 391, and the switch 323 automatically bounces back to its original position to continue fixedly adsorbing the newly entered container 80 on the turntable 30.

[0052] As Figure 8 shown, in some examples, furthermore, a pressure sensor 381 is also arranged inside the gas storage tank. The pressure sensor is used to monitor the negative pressure parameter inside the gas storage tank in real time, so as to reflect the suction force of the suction nozzle 322.

[0053] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
