Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, in particular to a filling and sealing packaging equipment applied to a rotating table. Background Art

[0002] Traditional rotary filling equipment is prone to violent shaking of the liquid due to container inertia during high-speed start and stop stages, especially for volatile or foaming liquids (such as alcohol, carbonated beverages, cosmetics, etc.). The imbalance of liquid surface tension will cause a large amount of foam to be generated or even burst and splash, resulting in reduced packaging accuracy and sealing failure. Existing technologies mostly suppress shaking by reducing the turntable speed or increasing the mechanical clamping strength, but the former sacrifices production efficiency, and the latter is prone to container deformation or damage due to rigid clamping. In addition, conventional upright filling is difficult to balance liquid level stability and start-stop inertia compensation, especially during the turntable acceleration and deceleration stages. The difference in liquid inertia direction causes the single tilt strategy to fail, and dynamic posture adaptation cannot be achieved, which ultimately affects the sealing tightness and packaging yield.

[0018] See also Figures 1 to 9 As shown, the embodiment of the present application provides a filling and sealing packaging device applied to a rotating table, including a packaging bin 10, and also including: an input device 20, a rotating table 30, a filling station 40, an inner cover supply device 50, an outer cover supply device 60 and a container 80; Specifically, the input device 20 is used to input the container 80 to be packaged into the packaging bin 10; the rotating 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 rotating table 30, and 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 component 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 rotating table 30; the inner cover supply device 50 Located at the rear side of the filling station 40, the inner cover supply device 50 corresponds to the crimping station 51 of the rotating table 30; the outer cover supply device 60 is located at the rear side of the inner cover supply device 50, and the outer cover supply device 60 corresponds to the capping station 61 of the rotating table 30; wherein, the container 80 is rotated by the steering adsorption component 32, and is arranged in an inclined state in the arc chamfer 33 of the clamping position 31, when the rotating table 30 is at the moment of rotation or stop, the inclination direction of the container 80 located at the filling station 40 or at the crimping station 51 is opposite.

[0019] The present application provides a filling and sealing packaging equipment applied to a rotating table, wherein a rotating table 30 is provided in a packaging bin 10, and a plurality of clamping positions 31 with four-corner arc chamfers 33 are arranged circumferentially on the rotating table 30, and a steering adsorption component 32 is arranged in the middle of each clamping position 31, which enables the container 80 to tilt and rotate by negative pressure adsorption at the middle position of the container 80; the input device 20 continuously transports the container 80 to the starting position of the rotating table 30, and when the rotating table 30 rotates, the clamping position 31 causes the container 80 to have a first tilt angle (10-15°) posture at the filling station 40, and uses the surface tension of the liquid to stabilize the liquid surface. At the moment the rotating table 30 rotates, the container 80 tilts in the opposite direction to form a dynamic balance; when the filling is completed and the container is transferred to the inner cover pressing station 51, the steering adsorption component 32 causes the container 80 to have a reverse tilt angle (10-15°) posture, which is also The liquid surface tension is utilized to stabilize the liquid surface. When the rotating table 30 rotates, the container 80 tilts in the opposite direction to form a dynamic balance. However, the tilting direction is opposite to the aforementioned direction, corresponding to the two states of acceleration state and deceleration stop state when the rotating table 30 starts to rotate. Subsequently, the outer cover of the outer cover supply device 60 is supplied and screwed at the capping station 61 to complete the sealing. Therefore, the present application adopts the rotating table 30 structure, and the inertia compensation in the start-stop stage is achieved through the reverse tilting of the double stations. The container 80 tilts forward in the acceleration stage and tilts backward in the deceleration stage, which effectively suppresses the shaking of the liquid. The buffering guide structure of the arc chamfer 33 provides the container 80 with tilting space and flexible clamping, thereby effectively avoiding the filling of liquid materials that are prone to foaming, and avoiding the tiny liquid splashing caused by foam rupture and defoaming, thereby enhancing the packaging sealing effect of the equipment.

[0020] like Figures 1 to 9 As shown, in some examples, further, the rotating table 30 is provided with: an elastic reset support part, an air tank 35, an edge friction mechanism 36, a rotary power mechanism 37 and a negative pressure air pump 38, the elastic reset support part is fixedly connected to the inner side of the rotating table 30 and the arc chamfer 33, and can contact the outer wall of the container 80, so as to drive the container 80 to maintain an upright state; the air tank 35 is arranged in the middle of the rotating table 30, the air tank 35 is in a negative pressure state, and is connected to all the steering adsorption components 32; the rotary power mechanism 37 is fixedly arranged below the rotating table 30, and the driving end of the rotary power mechanism 37 is connected to the rotating table 30, so as to drive the rotating table 30 to rotate horizontally; the negative pressure air pump 38 is connected to the air tank 35; the edge friction mechanism 36 is arranged on the outer side of the rotating table 30, and the edge friction mechanism 36 can contact the outer wall of the lower half of the container 80.

[0021] In this embodiment, the elastic reset support portion added to the rotating table 30 forms a flexible contact with the outer wall of the container 80 through the elastic contact surface on 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 the container 80 is tilted by the synergistic effect of the friction resistance and the steering adsorption component 32 when the rotating table 30 rotates. When the rotating table 30 starts to accelerate, the edge friction mechanism 36 applies lateral resistance to the container 80, and the steering adsorption component 32 adsorbs the middle of the container 80 and drives it to tilt forward, so that the container 80 deflects to the arc chamfer 33 support When the rotating table 30 decelerates and stops, the edge friction mechanism 36 is blocked in the reverse direction, and the steering adsorption assembly 32 causes the container 80 to tilt backward; the elastic reset support portion assists the container 80 in maintaining an upright reference position during the filling and inner cover buckling process, and provides a buffer through the arc chamfer 33 and the outer wall of the container 80 during the tilting process. When the rotary power mechanism 37 drives the rotating table 30 to rotate horizontally, the steering adsorption assembly 32 and the edge friction mechanism 36 dynamically cooperate to realize the switching of the tilting direction of the container 80, and reduce the liquid disturbance by adjusting the balance posture.

[0022] like Figure 3 and Fig. 9 As shown, in some examples, further, the rotating table 30 is also connected with: a support table 39 and a limit bar 391, the top end face of the support table 39 has an arc-shaped plane, and is arranged at the bottom edge of the rotating table 30, for supporting the bottom of the container 80 in the rotating conveying process; the limit bar 391 is arranged on the top end of the support table 39, the limit bar 391 is arc-shaped, and is located between the input device 20 and the output device 70, for mechanically triggering the steering adsorption component 32 to close when it is in the non-working area.

[0023] In this embodiment, the support platform 39 provides a continuous supporting surface for the bottom of the container 80 through the arc-shaped plane at the bottom edge, and its arc-shaped end surface is between the crimping station 51 and the input device 20. The container 80 needs to be supported during crimping, screwing the outer cover, inputting and outputting the container 80. In a working range where the container 80 performs a tilting action, that is, between the filling station 40 and the crimping station 51, the bottom of the container 80 does not need to be supported, so as to provide the bottom of the container 80 with sufficient space for the container 80 to perform a fine angle of tilting and turning; the arc-shaped trajectory of the limit strip 391 is the same as the rotation path of the rotating table 30. Axis arrangement, when the clamped container 80 moves to the non-working section between the input device 20 and the output device 70, the limit bar 391 mechanically and physically contacts the control valve switch 323 of the steering adsorption component 32, forcing the negative pressure adsorption function to be closed, so that the container 80 turns off the adsorption function in the non-working area to reduce energy consumption and noise; at the same time, before entering the output device 70, the steering adsorption component 32 rotates with the rotating table 30 to enter the position of the limit bar 391, and automatically turns off the adsorption after contacting the limit bar 391, so that the packaged container 80 can easily break away from the adsorption and be sent out from the output device 70.

[0024] like Figure 2 , Figure 7 and Figure 8 As shown, in some examples, further, the steering adsorption component 32 includes: multiple air circuit connecting tubes 321, suction nozzles 322 and switches 323, one end of the multiple air circuit connecting tubes 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 set in the middle position of the inner wall of the clamping position 31, and the suction nozzle 322 is connected to the air circuit connecting tube 321; the switch 323 is mounted on the air circuit connecting tube 321, the switch 323 is a push-type switch 323, and the switch 323 is in a pop-up open state by default.

[0025] In this embodiment, the air path connecting pipe 321 of the steering adsorption assembly 32 is distributed radially along the rotating table 30, and the negative pressure of the gas storage tank 35 is transmitted to the suction nozzle 322 in the middle of each clamping position 31. The suction nozzle 322 is rotated through the shaft structure to further realize the suction nozzle 322 following the tilting rotation of the container 80, and synchronously maintain the positioning effect of the container 80; when the container 80 enters the clamping position 31, its outer wall contacts the suction nozzle 322, and the negative pressure adsorption takes effect, and the suction nozzle 322 rotates with the force state of the container 80; in the non-working area, the arc-shaped protrusion of the limit strip 391 is formed. The switch 323 is mechanically pushed back to the reset rod, forcing the switch 323 to switch to the closed state to disconnect the passage between the air circuit connecting pipe 321 and the air storage tank 35; when the rotating table 30 rotates to the position of the input device 20, the suction nozzle 322 is out of the range of the limit bar 391, and the switch 323 automatically pops up to restore the negative pressure adsorption. At this time, the suction nozzle 322 is tightly attached to the middle outer wall of the container 80 under the action of the negative pressure of the air circuit connecting pipe 321. Therefore, in this example, the adsorption effect can be started and stopped at an appropriate time through the mechanical trigger mechanism of the switch 323, and the start and stop timing is adapted to the switching process of the workstation.

[0026] like Figure 2 and Figure 7 As shown, in some examples, further, the elastic reset support portion includes an elastic gas column 34, one end of the elastic gas column 34 is fixedly connected to the end face of the arc chamfer 33, the elastic gas column 34 is perpendicular to the side wall of the container 80, and the end of the elastic gas column 34 close to the container 80 is a flexible sealed material.

[0027] In this embodiment, the elastic gas column 34 is evenly distributed along the circumference of the end face of the arc chamfer 33 of the clamping position 31, and its fixed end is fixedly connected to the rotating table 30, and the free end adopts a hemispherical silicone sealed head to vertically contact the side wall of the container 80; when the steering adsorption component 32 adsorbs the middle of the container 80 through the suction nozzle 322 and drives it to tilt, the elastic gas column 34 is compressed and deformed by the lateral pressure of the container 80, and the internal gas generates buffer damping through the closed flexible cavity, and at the same time stores elastic reset potential energy; when it is located at the processing station to be executed, the elastic restoring force of the elastic gas column 34 pushes the container 80 to restore to an upright state, and at this time, the vertical contact surface between the flexible sealed 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 makes it possible for the container 80 to always have a tendency to restore to an upright state through the setting of the elastic gas column 34 during the rotation of the rotating table 30, and after the external force is removed from the container 80, it can be in an upright working state.

[0028] like Figure 7As shown, in some examples, further, the elastic gas column 34 is connected to a positive pressure gas storage structure, and the positive pressure gas storage structure includes: an upper annular container 341, a lower annular container 342 and a plurality of protrusions 343, the upper annular container 341 is fixedly arranged in the upper half of the inner cavity of the rotating table 30; the lower annular container 342 is fixedly arranged in the lower half of the inner cavity of the rotating table 30, and is connected to the upper annular container 341; a plurality of protrusions 343 are grouped in pairs, and are 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 protrusions 343 is connected to the elastic gas column 34.

[0029] In this embodiment, the positive pressure gas storage structure forms an annular air cavity by coaxially nesting the upper annular container 80 and the lower annular container 80, wherein the convex portion 343 of the upper annular container 341 and the corresponding convex portion 343 of the lower annular container 342 form a further pressure transmission channel; the fixed ends of the elastic gas columns 34 are respectively fixedly connected to the convex portions 343 of the outer walls of the upper annular container 80 and the lower annular container 80, so that the gas in the annular air cavity in the positive pressure state can be evenly transmitted to each elastic gas column 34; when the container 80 is driven to tilt by the edge friction mechanism 36, an elastic lossless support can be formed by the elastic gas column 34; when the rotating table 30 is stationary, the positive pressure gas in the upper annular container 80 and the lower annular container 80 drives each elastic gas column 34 to extend and reset through the convex portion 343, forcing the container 80 to return to an upright state.

[0030] like Figures 3 to 6 As shown, in some examples, further, the edge friction mechanism 36 includes: an interception frame 361, a rotating belt 362 and a friction strip 363, the interception frame 361 is fixedly arranged on the outside of the rotating table 30, and the side wall of the interception frame 361 facing the clamping position 31 is arc-shaped and concentric with the rotating table 30; the rotating belt 362 is rotatably arranged in the arc-shaped inner cavity of the interception frame 361, and the side wall of the rotating belt 362 is attached to the inner wall of the inner cavity of the interception frame 361; the friction strip 363 passes through the strip-shaped through hole of the side wall of the interception frame 361, and protrudes from the outer wall of the interception 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.

[0031] In this embodiment, the interception frame 361 of the edge friction mechanism 36 forms a guide track through its arc-shaped side wall concentric with the rotating table 30, and the rotating belt 362 can rotate synchronously in the inner cavity of the interception frame 361 along the rotation direction of the rotating table 30; the friction strip 363 protrudes 3-5mm from the outer wall of the interception frame 361 through the strip-shaped through hole, and the exposed surface of the friction strip 363 forms continuous friction 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 strip 363; because the friction strip 363 is connected to the interception frame through the rotating belt 362 The inner cavity 361 is slidably connected, and the rotation of the rotating belt 362 lags slightly behind the rotating table 30, causing the friction strip 363 to apply radial friction force to the container 80, forcing the suction nozzle 322 in the middle of the container 80 to deflect; in the acceleration stage of the rotating table 30, the friction strip 363 forces the container 80 to tilt forward in the rotation direction through contact pressure, and in the deceleration stage, it forces the container 80 to tilt backward in the rotation 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, thereby reducing the possibility of foam generation.

[0032] like Figures 4 to 6 As shown, in some examples, further, a plurality of inertial hangers 364 are equidistantly arranged at the bottom end of the friction strip 363 , a flexible connecting rope is provided between the inertial hanger 364 and the rotating belt 362 , and the lower half of the inertial hanger 364 is a counterweight block for providing inertial rotation of the rotating belt 362 .

[0033] In this embodiment, the inertial hanger 364 forms a dynamic coupling mechanism with the rotating belt 362 through a flexible connecting rope. When the rotating table 30 accelerates, the counterweight block produces a lagging displacement due to gravity, and applies a pulling force to the rotating belt 362 through the connecting rope, so that the contact between the friction strip 363 and the outer wall of the container 80 produces a relative displacement, forcing the container 80 to rotate and tilt forward; when the rotating table 30 decelerates, when the rotating table 30 decelerates to stop, the counterweight block lags behind the rotating table 30 due to inertia, and applies a pulling force to the rotating belt 362 through the connecting rope, so that the contact between the friction strip 363 that continues to be in a rotating state and the outer wall of the container 80 produces a relative displacement in the opposite direction, forcing the container 80 to rotate in the opposite direction and tilt backward; preventing the solution inside the container 80 from overflowing due to the inertia of movement, while reducing the disturbance between the solution and the container 80, and reducing the amount of foam generated.

[0034] In some examples, further, in order to further realize that the container 80 on the rotating table 30 can have a more accurate and adjustable anti-disturbance effect, in this example, the counterweight block is replaceable. According to the different weights of the counterweight, the movement of the container 80 drives the friction strip 363 equipped with different weight counterweight blocks to rotate with different difficulties. For example, the friction strip 363 and the rotating belt 362 equipped with lighter counterweight blocks are easier to rotate with the rotating table 30, and vice versa. Therefore, the tilt angle of the container 80 also has a change in a related proportion; furthermore, the positive pressure gas storage structure is also provided with a gas replenishment inlet, and a pressure gauge is provided in the positive pressure gas storage structure, and the gas pressure in the elastic gas column 34 is adjusted through the gas replenishment inlet, so that the gas pressure in the elastic gas column 34 can also be adjusted as needed. When the pressure increases, the difficulty of rotating the container 80 will also increase. Therefore, the gas pressure in the positive pressure gas storage structure can be adjusted, and the tilt angle of the container 80 when switching between workstations can be adjusted synchronously.

[0035] like Figure 4 and Figure 5 As shown, in some examples, further, a plurality of arc-shaped concentric grooves 301 are provided at the bottom end of the rotating table 30 , the switch 323 is located in the groove 301 , and the groove 301 is aligned with the position of the limit strip 391 .

[0036] In this embodiment, the arc-shaped concentric grooves 301 at the bottom end of the rotating table 30 are distributed at equal angles along the rotation axis of the rotating table 30; the switch 323 is embedded in the inner cavity of the groove 301, and its pressing contact is flush with the opening plane of the groove 301. When the rotating table 30 rotates to the position of the limit bar 391, the arc-shaped protrusion of the limit bar 391 is just inserted into the groove 301 and presses down the switch 323 contact to achieve mechanical triggering. The suction nozzle 322 at the current position will not inhale. When the rotating table 30 continues to rotate, the groove 301 is out of the range of action of the limit bar 391, and the switch 323 automatically pops up and resets, and continues to fix and adsorb the new container 80 that enters the rotating table 30.
