[0022] Beneficial effects:

[0023] 1. The present invention sequentially arranges a loading station, a filling station, a plug pressing station, a cap screwing station and a material unloading inspection station on a bottle circulation conveyor line to complete the entire production process from empty bottles to filling, bottling, plugging and capping, which greatly reduces the labor cost in the filling, plugging and capping process.

[0024] 2. The first bottle mold assembly and the second bottle mold assembly arranged on the bottle body circulation conveyor line designed by the present invention can clamp the bottle body to be filled and keep the bottle body running stably. Moreover, the first circulation transmission line and the second circulation transmission line are circulation transmission lines, which can drive the first bottle mold assembly and the second bottle mold assembly thereon to realize periodic circulation, thereby improving the utilization rate of the bottle mold assembly. In addition, the present invention arranges the first bottle mold assembly and the second bottle mold assembly on two transmission lines respectively, so as to facilitate the adjustment of the spacing between the first bottle mold assembly and the second bottle mold assembly and adapt to different product bottle body sizes.

[0025] 3. The present invention designs a linkage adjustment drive mechanism, in which the first circulating conveyor belt and the second circulating conveyor line are driven by only one set of drive mechanism. When the bottle body needs to be clamped and moved synchronously, the locking mechanism is used to lock the adjustment wheel, the linkage wheel and the output shaft, and the first drive motor directly drives the linkage wheel and the adjustment wheel to move together, so as to realize the synchronous movement of the first circulating conveyor line and the second circulating conveyor line. When the spacing between the paired bottle mold assemblies needs to be adjusted, the locking mechanism is not locked, and the adjustment wheel is manually rotated to drive the adjustment wheel and the first circulating conveyor belt thereon, so as to adjust the spacing between the paired bottle mold assemblies; or the first drive motor drives the output shaft to rotate to drive the linkage wheel and the second circulating conveyor belt thereon to rotate, so as to adjust the spacing between the paired bottle mold assemblies.

[0026] 4. The locking mechanism of the present invention inserts the locking shaft, which is directly inserted into the clamping copper ring and is locked by thread. At this time, the adjusting wheel, the linkage wheel and the clamping copper ring therein are locked together, so that after the linkage wheel rotates to drive the locking shaft to rotate, the clamping copper ring and the adjusting wheel can move synchronously. In addition, an adjusting arc groove is provided on the linkage wheel, and the locking shaft is adjusted in the adjusting arc groove of the linkage wheel. The length of the adjusting arc groove is the adjustment range of the spacing between the paired bottle mold assemblies.

[0027] 5. The multi-station follow-up filling mechanism of the present invention separates the feeding part from the filling part by setting a feeding trolley assembly and a multi-station filling translation assembly. The feeding trolley and the multi-station filling translation assembly are detachably connected. In this way, when the liquid material needs to be replaced, only the feeding trolley assembly needs to be replaced, and the entire filling machine does not need to be replaced or cleaned, which is convenient for maintenance. The filling material is controlled by a three-way valve to facilitate accurate filling. A multi-station filling translation assembly is set, that is, multiple filling heads are set on the filling machine to achieve the filling of multiple bottles at the same time.

[0028] 6. The present invention controls the filling amount through a piston cylinder at the second opening position of the three-way valve, and drives the piston rod to extend and retract up and down through the piston rod driving mechanism. The piston rod moves downward to enable the liquid material in the silo to enter the piston cylinder through the three-way valve, and the piston rod moves upward to enable the liquid material in the piston cylinder to enter the hose and the filling head through the third opening to achieve filling. The up and down movement of the piston rod is achieved by a ball screw, and the first drive motor drives the ball screw to rotate to drive the piston rod fixed base to move up and down, and drive the piston rod to move up and down.

[0029] 7. The present invention also sets a switch cylinder at the switch position of the three-way valve. The switch cylinder is extended and retracted to drive the rotating piece to rotate, so as to realize the opening and closing of the three-way valve. In this way, when filling is not required, the three-way valve switch can be used to close the gap between the silo and the three-way valve to prevent leakage of liquid materials. In addition, before the feeding trolley assembly is docked or when it needs to leave the filling machine, the piston rod is driven to leave the piston cylinder by the first drive motor. At this time, the three-way valve switch needs to be closed by the switch cylinder to prevent leakage of liquid materials. When docking, the three-way valve switch also needs to be closed to prevent the piston rod from affecting the liquid material when docking with the piston cylinder.

[0030] 8. The present invention also sets a height adjustment component on the trolley. On the one hand, the height of the feeding platform is adjusted so that the feeding platform on the feeding trolley component can adapt to different filling machine heights. The height adjustment screw is rotated by the hand wheel to make the feeding platform move up and down on the height adjustment screw. The slide rails on both sides play a role of stable guidance. After adjusting to a certain height, the feeding platform is placed on the filling machine frame and fixed on the filling machine frame by a detachable connection. On the other hand, the height adjustment component is used to adjust the trolley together with the adjustment plate and the triangular fixing plate thereon to move downward and leave the feeding platform. After that, the trolley can be moved away from the multi-station follow-up filling mechanism, so that the trolley can achieve multiple uses and then transfer other feeding platforms and silos.

[0031] 9. The present invention sets the filling head on the first transverse drive assembly, so that the filling head moves along the transmission direction of the bottle conveyor line with the first transverse drive assembly, so that during filling, the filling head can be transmitted along with the bottle, and filling can be achieved without stopping the bottle conveyor line, thereby improving the filling efficiency. In addition, the first longitudinal drive assembly can drive the filling head to move up and down to adapt to the filling of bottles of different heights, and when filling is not required, the filling head is driven to move up without affecting the work of the bottle conveyor line itself.

[0032] 10. The inner plug pressing mechanism designed in the present invention presses the inner plug by pressing the pressing rubber block fixed at the end of the pressing cylinder without affecting the bottle body. In addition, a first proximity switch is placed on one side to sense that the bottle body has passed through the bottle body circulation conveyor line and has reached the end position of the pressing cylinder, thereby achieving precise control.

[0033] 11. The present invention grasps the bottle body and the bottle cap separately, the bottle body is limited and fixed by the bottle body stabilizing clamp, the bottle cap screwing clamp grasps the bottle cap to realize the rotation of the bottle cap, and the up and down movement of the bottle body stabilizing clamp and the bottle cap screwing clamp is realized by the second longitudinal drive component. While the bottle body and the bottle cap are grasped separately, the function of following the movement of the bottle body circulating conveyor line is realized by the two transverse drive components, so that the operation of screwing the bottle cap can be completed without stopping the conveyor line, which greatly improves the work efficiency.

[0034] 12. The rotary drive assembly of the present invention can realize the rotation of the rotating shaft through a servo motor, and the rotation of the rotating shaft drives the bottle cap screwing claws arranged thereon to rotate to realize the screwing operation. The clamping cylinder realizes the rotation of the bottle cap screwing claws on the side of the conical column by extending and retracting up and down, and realizes the contraction and opening of the bottle cap screwing claws during rotation. The conical column is designed to be narrow at the bottom and thick at the top, so that the bottle cap screwing claws open when the conical column moves downward, and the bottle cap screwing claws shrink when the conical column moves upward. During the screwing process, the rotating shaft rotates, one end of the spring is set on the rotating shaft, and the other end is connected to the sleeve below, causing the spring thereon to be rotated and compressed, so that the limiting sleeve at the end of the spring is driven downward to cover a certain screwing stroke.

[0035] 13. A connecting rod is provided at the end of the conical column of the present invention, and the connecting rod does not rotate with the conical column. Thus, during the overall rotation of the rotating shaft, the clamping plate and the limiting rod at the end of the connecting rod do not rotate, so that when the bottle cap with the pump head is screwed, the pump head can be limited. In order to ensure that the connecting rod does not rotate with the conical column, a limiting notch is provided in the sleeve at the end of the clamping cylinder, and the limiting column connected to the connecting rod is directly inserted into the limiting notch. During the rotation of the rotating shaft, the connecting rod does not rotate with the outer rotating shaft under the action of the limiting column, thereby realizing the limiting effect.

[0036] 14. The unloading gripper group designed by the present invention directly realizes grabbing and releasing through a two-way telescopic cylinder, and is realized through a mechanical arm, so as to realize automatic unloading operation. In addition, before unloading, the bottles on the bottle circulation conveyor line are also detected, and the second proximity switch is used to detect whether there is a bottle cap on the bottle body, and the height of the bottle cap is detected by the micro switch. The height of a normal threaded cap is determined after it is screwed into place. If the thread is skewed during the screwing process, the bottle cap cannot be screwed into place, and its height must be different from that under normal circumstances. The abnormal bottle body is detected by the micro switch, and the defective products can be grabbed to the defective product conveyor line by the unloading gripper group at a later stage, and the normal products can be grabbed to the finished product conveyor line by the unloading gripper group.

[0048] In addition, in order to limit the position of the protrusion 117 during installation, one end of the slide groove 116 extends to the edge of one end of the base 114, and the other end is only opened to the position of one-half to three-quarters of the length of the base 114, and does not extend to the edge of the other end of the base 114. That is to say, the protrusion 117 is inserted into the slide groove 116 from one side, and pushed forward with force until it can no longer be pushed, and then it is installed in place.

[0049] In this embodiment, the slide groove 116 is designed to be a T-shaped groove. In addition, at least one ball spring plunger 118 is arranged in the base 114. The ball spring plunger 118 is arranged opposite to the inner surface of the slide groove 116 and the ball at the end of the ball spring plunger 118 protrudes from the inner surface of the slide groove 116. A first limiting notch 119 is arranged at a position corresponding to the ball spring plunger 118 on the surface of the protrusion 117. A pair of ball spring plungers 118 are arranged. When the ball at the end of the ball spring plunger 118 is inserted into the bottle mold clamp 115, it rolls and contacts with the bottle mold clamp 115 to reduce friction.

[0050] In order to facilitate the installation of the bottle mold clamp 115 into the base 114, a chamfer 122 is further provided at a position of the base 114 corresponding to the edge of the slide groove 116. When inserting, the chamfer 122 plays a guiding role.

[0051] In order to facilitate the disassembly of the bottle mold clamp 115 , a disassembly cylinder 120 is further provided on one side of the base 114 , and a push block 121 is provided at the execution end of the disassembly cylinder 120 , which is arranged along the extension direction of the slide slot 116 and the push block 121 is directly opposite to the bottle mold clamp 115 .

[0052] Since one end of the slide groove 116 designed in the present invention extends to the edge of one end of the base 114, and the other end is only opened to the position of one-half to three-quarters of the length of the base 114, and does not extend to the edge of the other end of the base 114, the disassembly cylinder 120 is designed in this embodiment to extend in the direction of the slide groove 116 extending to the edge of one end of the base 114, and the push block 121 is opposite to the bottle mold clamping block 115. When disassembly is required, the disassembly cylinder 120 is extended, and the bottle mold clamping block 115 slides along the slide groove 116 under the action of force until it leaves the base 114.

[0063] See also Figure 17 to Figure 23 The bottle stopper screwing mechanism 51 includes at least one group of bottle body stabilizing jaws 5101 and bottle cap screwing jaws 5102. The bottle body stabilizing jaws 5101 are fixed on the jaw driving assembly, and the bottle cap screwing jaws 5102 are arranged on the rotating driving assembly. The bottle body stabilizing gripper 5101 and the bottle cap screwing jaws 5102 are both arranged on the second longitudinal driving assembly, and the second longitudinal driving assembly is arranged on the second transverse driving assembly. The second transverse driving assembly drives the second longitudinal driving assembly and the bottle body stabilizing gripper 5101 and the bottle cap screwing jaws 5102 arranged thereon to move along the transmission direction of the bottle body circulating conveyor line 1, and the transmission speed is consistent with the transmission speed of the bottle body circulating conveyor line 1. The second longitudinal driving assembly drives the bottle body stabilizing jaws 5101 and the bottle cap screwing jaws 5102 to move up and down.

[0064] The rotary drive assembly includes a servo motor 5103, a clamping cylinder 5104, a pulley assembly 5105 and a rotating shaft 5106. The servo motor 5103 is connected to the rotating shaft 5106 through the pulley assembly 5105. The upper end of the rotating shaft 5106 is connected to the clamping cylinder 5104 through a bearing, and the lower end is connected to a tapered column 5107 which is narrow at the bottom and thick at the top. The side of the tapered column 5107 is in rotational contact with a pair of bottle cap screwing claws 5102, and the upper ends of the bottle cap screwing claws 5102 are limited and fixed to the limiting sleeve 5109 through a rubber ring 5108. The limiting sleeve 5109 is sleeved on the outer side of the tapered column 5107. A spring 5110 is also sleeved on the rotating shaft 5106. The upper end of the spring 5110 is fixed to the rotating shaft 5106, and the lower end is fixed to the upper end of the limiting sleeve 5109.

[0065] In addition, for the cosmetic bottle body 9, some cosmetic bottle bodies 9 may have a pump head on their bottle caps, so a connecting rod 5111 that does not rotate with the conical column 5107 and the rotating shaft 5106 is also provided through the conical column 5107 and the rotating shaft 5106, and the end of the connecting rod 5111 is clamped and connected to the limiting rod 5113 by a clamping plate 5112; a sleeve shell 5114 is provided at the end of the clamping cylinder 5104, and the lower end of the sleeve shell 5114 is connected to the rotating shaft 5106 through a bearing, the connecting rod 5111 extends into the sleeve shell 5114, and a second limiting groove 5115 is provided on the side of the sleeve shell 5114, and the upper end of the connecting rod 5111 is connected to the limiting column 5116, and the limiting column 5116 is inserted into the second limiting groove 5115.

[0066] When the bottle cap is specifically screwed, the bottle cap screwing jaw 5102 is rotated on the conical column 5107 by the upward and downward extension of the clamping cylinder 5104. When the conical column 5107 moves downward, the bottle cap screwing jaw 5102 opens because the upper end of the conical column 5107 is thick. When the conical column 5107 moves upward, the bottle cap screwing jaw 5102 shrinks because the lower end of the conical column 5107 is narrow, and the grasping and clamping operation of the bottle cap screwing jaw 5102 is realized at this time. After grasping and clamping, the rotating shaft 5106 is driven to rotate by the servo motor 5103, and the bottle cap screwing jaw 5102 at the lower end is driven to rotate during the rotation process. At this time, the spring 5110 is deformed and compressed. In order to restore the state, the limiting sleeve 5109 at the lower end of the spring 5110 drives the bottle cap screwing jaw 5102 to move downward by a certain stroke. During the resetting process of the spring 5110, the stroke of the bottle cap screwing downward is covered.

[0067] During the rotation of the rotating shaft 5106, the middle connecting rod 5111 plays a limiting role because the limiting column 5116 is inserted into the second limiting notch 5115, so it does not rotate with the tapered column 5107 and the rotating shaft 5106. When the clamping cylinder 5104 is extended and retracted up and down, the sleeve 5114 below it is driven to move up and down to realize the up and down movement of the entire tapered column 5107 and the rotating shaft 5106. The lower end of the sleeve 5114 is connected to the rotating shaft 5106 through a bearing, and the rotation of the rotating shaft 5106 does not affect the fixed position of the sleeve 5114. During the screwing process, the limiting rod 5113 at the end of the connecting rod 5111, which is clamped and connected by the clamping plate 5112, can have a slight contact with the bottle cap or leave a small gap, which plays a limiting role on the pump head. During the rotation of the bottle cap, the pump head does not rotate with it.

[0068] The second longitudinal drive assembly includes a fourth drive motor 5118, a first gear 5119, and a first rack 5120. The output shaft of the first drive motor 5118 is connected to the first gear 5119. The first gear 5119 is meshed with a vertically arranged first rack 5120. The first rack 5120 is connected to a clamping jaw drive assembly and a rotation drive assembly via a first connecting plate 5121. The second longitudinal drive assembly also includes a pair of longitudinal slide rails 5122. Both ends of the first connecting plate 5121 are slidably connected to the pair of longitudinal slide rails 5122.

[0069] In order to achieve the grasping of the bottle stabilizing clamp 5101 and the bottle cap screwing clamp 5102 without affecting the transportation of the bottle body transmission line, the entire second longitudinal drive assembly and the bottle stabilizing clamp 5101 and the bottle cap screwing clamp 5102 thereon are arranged on the second transverse drive assembly, including the fifth drive motor 5123, the second gear 5124, and the second rack 5125. The output shaft of the second drive motor 5123 is connected to the second gear 5124, and the second gear 5124 is meshed with the transversely arranged second rack 5125. The second rack 5125 is connected to the second longitudinal drive assembly through the second connecting plate 5126. The second transverse drive assembly also includes a pair of transverse slide rails 5127, and the second connecting plate 5126 is slidably connected to the pair of transverse slide rails 5127 at both sides.

[0070] For different bottles 9, the distance between the bottle cap and the bottle body is not fixed. Some bottle caps are higher in height, so it is necessary to properly adjust the height of the bottle body stabilizing clamp 5101. Therefore, the bottle body stabilizing clamp 5101 is set on the height adjustment mechanism, which includes a clamp block 5128 fixed on the first connecting plate 5121, and a second height adjustment screw 5129 is passed through the clamp block 5128. The second height adjustment screw 5129 is threadedly connected to the clamp driving assembly through the third connecting plate 5131. A pair of guide rods 5130 are also passed through the clamp block 5128, and the lower ends of the pair of guide rods 5130 are connected to the third connecting plate 5131. A second adjustment hand wheel 5132 is set at the upper end of the second height adjustment screw 5129, and the rotation of the second height adjustment screw 5129 is controlled by the second adjustment hand wheel 5132, so as to control the third connecting plate 5131 and the clamp driving assembly thereon to adjust up and down. In this embodiment, the clamp driving assembly is realized by a first bidirectional telescopic cylinder 5117.

[0073] A defective product conveying line 7 and a finished product conveying line 8 are also provided on one side of the unloading gripper mechanism 61 . The unloading gripper mechanism 61 grabs the bottles on the bottle circulation conveying line 1 and unloads them to the defective product conveying line 7 or the finished product conveying line 8 .

[0074] Working principle: 1. The feeding trolley assembly transfers the silo 3103 to the filling station 3 through the trolley 3102. At this time, the output end of the silo 3103 is connected to the first opening of the three-way valve 3106. When docking with the multi-station follow-up filling mechanism 31, the second opening of the three-way valve 3106 is connected to the discharge drive assembly, and the third opening of the three-way valve 3106 is connected to the hose 3104. The hose 3104 is connected to the filling head 3115 of the multi-station filling translation assembly; the bottle body 9 is placed on the bottle body circulation conveyor line 1 by a mechanical arm or manually, and the bottle body circulation conveyor line 1 is started. The bottle mold assembly clamps the bottle body 9 and moves forward, passing through the filling station 3, the plug pressing station 4, the upper cover screwing station 5, and the material unloading detection station 6 in sequence.

[0075] 2. The bottle 9 passes through the multi-station and follows the filling mechanism 31. The switch cylinder 3110 controls the three-way valve 3106 to open. The third drive motor 3131 drives the ball screw 3132 to rotate, driving the piston rod 3108 to move downward, transferring the liquid in the silo 3103 to the piston cylinder 3107. The third drive motor 3131 is driven again to push the piston rod 3108 upward. The liquid enters the hose 3104 through the third opening of the three-way valve 3106 and is then filled into the bottle through the filling head 3115. During the filling, the first longitudinal drive assembly and the first transverse drive assembly work together to drive the multiple filling heads 3115 to move along the transmission direction of the bottle circulation conveyor line 1. After one round of filling is completed, they return to their original position for the next filling.

[0076] 3. After the filling is completed, the bottle is passed through the plug pressing station 4. Before the plug pressing station 4, the inner plug can be placed at the bottle mouth by a mechanical arm or manually. After passing through the plug pressing station 4, the inner plug is pressed into the bottle mouth by the pressing cylinder 4102.

[0077] 4. After the plugging is completed, the bottle cap can be placed on the bottle mouth by a mechanical arm or manually before the upper cover screwing station 5 through the upper cover screwing station 5, and the second longitudinal drive assembly drives the bottle body stabilizing clamp 5101 and the bottle cap screwing clamp 5102 to move downward, and the clamp driving assembly grabs the bottle body 9 and controls the rotating driving assembly to grab the bottle cap and rotate, controls the clamping cylinder 5104 to move up and down to realize the bottle cap screwing clamp 5102 to grab the bottle cap, and the servo motor 5103 drives the rotating shaft 5106 to rotate to realize the screwing of the bottle cap. While screwing, the second transverse drive assembly works, controls the second longitudinal drive assembly and the bottle body stabilizing clamp 5101 and the bottle cap screwing clamp 5102 thereon to move along the transmission direction of the bottle body circulation conveyor line 1, and returns to the original position after one round of bottle cap screwing is completed for the next bottle cap screwing.

[0078] 5. After the bottle cap is screwed, it passes through the unloading detection station 6, and determines whether there is a bottle cap on the bottle body 9 and whether the bottle cap is screwed in place through the second proximity switch 6105 and the micro switch 6106. After the detection, the unloading robot arm 6101 and the second two-way telescopic cylinder 6103 are used to control the unloading gripper group 6102 to grab the finished product or defective product and place it on the corresponding conveyor belt to complete a round of product production.

[0079] 6. After the product is unloaded at the unloading inspection station 6, the bottle body circulation conveyor line circulates and drives the bottle mold assembly thereon to follow the first circulation conveyor line 101 and the second circulation conveyor line 102 to return to the loading station 2.
