DETAILED DESCRIPTION

[0029] The application will be further described below Figures 1 to 8 The application will be further described below

[0030] The application will be further described below Figure 1 The sterile cap screwing workstation provided by the application is installed on the upper part of the warehouse body of the sterile filling machine when used with the linear sterile filling machine, the bottle conveying mechanism in the warehouse body conveys the bottles that have completed filling to the sterile cap screwing workstation, and the sterile cap screwing machine is used to complete the final sterile sealing.

[0031] The application is divided into three parts from top to bottom, which are the cap arranging device 1 in the uppermost part, the sterilization warehouse 2 in the middle part, and the box sterile warehouse 3 in the lowermost part. When the cap is screwed by the sterile cap screwing machine provided by the application, the cap is first conveyed to the cap arranging device 1 of the application by the cap arranging conveyor, and then the cap is approximately evenly distributed to the 12 lower cap channels 9.

[0032] The upper part of the cap arranging device 1 is flat, and there is an entering cap port for single cap entering in the middle position of the upper part. The cap entering the cap arranging device 1 has been arranged in the correct direction. The middle part of the cap arranging device 1 is provided with a cap rubbing device driven by a cylinder. The cap rubbing device is used to divide the single channel entering cap into the 12 lower cap channels 9 through rubbing.

[0033] The cap rubbing device is actually a push plate driven by a cylinder. The push plate is installed above the cap channel. When the cylinder moves, the push plate moves. On the one hand, when the entering cap is unevenly distributed in the horizontal direction in the cap warehouse, the cylinder moves to drive the cap to move left and right, so that the cap is approximately evenly arranged in the horizontal direction. On the other hand, when the cap falls to the lower cap channel 9, the cap rubbing device moves left and right under the drive of the cylinder to break the connection between the caps, so that the cap falls into the lower cap channel 9.

[0034] When the lids from the 12 lower cover channels 9 fall into the sterilization chamber 2, they are first stopped by the cover-stopping device installed on the upper part of the sterilization chamber 2, and then sterilized by the spray from the sterilization nozzle 4. The H2O2 vaporized gas used for sterilization is generated by other equipment and then transported here. The sterilization nozzle 4 has an air inlet. The temperature control instrument installed on the sterilization nozzle 4 controls the temperature of the heater inside the sterilization nozzle 4.

[0035] like Figure 2 As shown, after sterilization, the lid slides down the lid channel into the lower section of the lid channel 9 inside the sterile chamber 3, where it is blocked by another lid-stopping device and dried by sterile hot air sprayed through the drying nozzle 5.

[0036] The lower cover channel 9 consists of 12 wire cover channels arranged below the upper cover distributor 1, extending downwards into the central sterilization chamber 2. A dust removal spray pipe is installed at the entrance of each wire cover channel. This pipe sprays sterile air to remove dust and debris from the covers before they enter the sterilization chamber 3. A collection hood is installed on the reverse side of the dust removal spray pipe to collect the polluted air.

[0037] The central sterilization chamber 4 is equipped with three servo motor-driven swivel nozzle structures. The nozzles (drying nozzle 5, sterilization nozzle 4, and dust removal nozzle) are fitted with coaxial sector gears on the outside of the sterilization chamber 2. The servo motors control the swivel angle of the nozzles through the sector gears.

[0038] The central cover sterilization chamber 2 is equipped with two cylinder-driven cover-stopping devices. The cover-stopping devices act simultaneously on 12 cover channels. The two cover-stopping devices are used to control the sterilization inlet position and the sterilization end outlet position of the lower cover channel, respectively.

[0039] The sterilization chamber 2 is equipped with a ball washing device in the upper and lower parts for cleaning and sterilization.

[0040] Inside the lowest sterile chamber 3, there are 12 wire mesh cover guides arranged at each station. A spray nozzle is installed behind each wire mesh cover guide. One end of the spray nozzle is connected to a rod-type heater, and the other end is used to supply sterile air. The dual-outlet nozzles on the spray nozzle face the wire mesh cover guides, providing drying sterile hot air for the sterilized covers. The spray nozzle is deflected and oscillated by a servo-driven oscillation mechanism. An independent fork-type cylinder cover-stopping device is installed at the front of each of the 12 wire mesh cover guides. The cover-stopping cylinder is protected by a corrugated rubber tube.

[0041] The above-mentioned use of cap stopper 1 is for situations where the lower cap channel 9 was originally without caps. For example, when the machine has just started, the lower cap channel 9 is not yet full of caps. Under continuous operation, the caps in the cap channel fall one by one. For each cycle of the aseptic filling machine, the aseptic capping machine of this invention works once and one cap falls, so there is no need to use cap stopper 1 to stop the caps.

[0042] A reciprocating cover feeding mechanism is arranged at the front of the cover slide opening, and is used to receive the cover released by the cover slide 9, and then hold the cover and feed it to the servo cover screwing head 6, so that the servo cover screwing head 6 can take the cover and screw the cover.

[0043] As shown in Figure 3 , after the cover is sterilized and dried, the cover is released by the cover stopping device arranged at the cover slide opening, and falls onto the cover feeding plate 16 of the reciprocating cover feeding mechanism, and is clamped by the corresponding cover clamping fingers 17.

[0044] The reciprocating cover feeding mechanism has a mounting frame 12 arranged on the left and right side plates of the lower sterile chamber 3 box. The left and right sides of the mounting frame 12 are respectively provided with a rack driving sliding block 13. The two guide rods of the sliding block 13 are fixed on the frame body of the mounting frame 12, and the sliding block 13 can move along the guide rods.

[0045] The cover on the cover feeding plate 16 is clamped and positioned in the process of being conveyed to the servo cover screwing head 6, as shown in Figure 2 and Figure 4 . When the cover is moved to the position directly below the servo cover screwing head 6, the push-pull rod 18 is actuated by the cam plate 14 to open the cover clamping fingers 17, and the servo cover screwing head 6 is first lowered and then raised by the lifting drive 7, thereby completing the cover taking action from the cover clamping fingers 17.

[0046] The long strip-shaped cover feeding plate 16 is provided with 12 cover clamping fingers 17. The 12 cover clamping fingers 17 are opened or clamped by a cam-driven push-pull rod 18. The push-pull rod 18 is actuated by the left and right cam plates 14 below the mounting frame 12 to open the cover clamping fingers 17 at the upper cover position (cover slide opening) to clamp the cover. The cover clamping fingers 17 clamp the cover during the cover conveying process, and the cover feeding plate 16 is moved to the cover position below the servo cover screwing head 6 to be opened again for the servo cover screwing head 6 to take the cover.

[0047] As shown in Figure 7 , the cover clamping fingers 17 include a left clamping piece 171 and a right clamping piece 172, which are respectively hinged to the cover feeding plate 16 through a rotating shaft. The connecting portions of the left clamping piece 171 and the right clamping piece 172 are engaged by a tooth 173, and there is a clamping space 174 between the left clamping piece 171 and the right clamping piece 172. The left clamping piece 171 is provided with a force receiving hole 176, and the push-pull rod 18 is provided with a radial thrust protrusion 175, which passes through the force receiving hole 176.

[0048] As shown in Figures 4 to 6 , after the cover is taken, the cover feeding mechanism is retreated to the cover taking position under the action of the servo drive. At this time, the servo cover screwing head 6 starts to descend and press the cover onto the bottle mouth directly below, and starts to screw the cover. The servo cover screwing head 6 is driven by the servo motor 19 to screw the cover. The torque of the screwing cover is preset in the program and controlled by the servo motor 19.

[0049] At the front of the exterior of the sterile chamber 3, there is a servo capping head mounting plate driven by a gear and rack structure, on which 12 servo capping heads 6 are mounted in a row. Each servo capping head 6 has one end of a rubber bellows located below the mounting plate, and the other end of the rubber bellows is mounted on the top of the sterile chamber body.

[0050] The servo cap screwing head 6 has the following structural features: a servo motor 19 and a reducer 20 are installed on the upper part of the servo cap screwing head 6, the middle part of the servo cap screwing head 6 is a sleeve structure with output shafts at both ends, and the lower part of the servo cap screwing head 6 is a cap screwer 22.

[0051] The servo cap tightening head 6 has a bushing 21 in the middle, through which the rotating shaft of the servo cap tightening head 6 passes. The lower end of the bushing 21 has a fixed bearing support connecting shaft 23, and the other end has a floating bearing support connecting shaft 23. This bearing is located in a seat, which is positioned on the upper part of the sleeve structure by its outer diameter.

[0052] The lower shaft section of the connecting shaft 23 of the cap screwer 22 is inserted into the main shaft seat 24 of the cap screwer 22. Five steel balls 30 arranged in a circular pattern on the upper part of the main shaft seat radially press against the corresponding number of recesses on the connecting shaft 23. The five steel balls 30 are pressed by the steel ball pressure ring 31 located on the outer ring of the main shaft seat. The steel ball pressure ring 31 is pressed by the compression spring 32.

[0053] The spindle seat is floatingly connected to its lower seat ring 26. The outer ring of the upper part of the seat ring 26 is equipped with another pressure spring 29 to provide preload for the floating connection. The seat ring 26 is threadedly connected to a guide limiting shaft 25, which passes radially through an oblong block 28. The oblong block 28 is inserted into one of the oblong holes on the periphery of the spindle seat 24 for limiting.

[0054] The lower part of the cap screwer's seat ring 26 is threaded to a cap screwing cup 27, and the cap screwing cup 27 uses a cap removal ball 275 pre-tightened by a rubber ring 276 to remove the cap.

[0055] like Figure 8 As shown, the screw cap cup 27 includes a cap cup body 271, the main body of the screw cap cup, and different cap shapes have different cap cup bodies 271; a sliding sleeve 272, which provides gravity for the top cap rod 274; a connector 273, which is used to connect the top cap rod 274 and the sliding sleeve 272; the top cap rod 274, which is used to push out unused caps to prevent the screw cap head from carrying the cap into the next working cycle; and a cap removal steel ball 275, which is used to clamp the cap.

[0056] The servo cap screwing head 6 has a spindle seat 24, a guide limit shaft 25, a seat ring 26, and a waist-shaped block 28, which provide connection floating and limit for the cap screwing device, and a compression spring 29 provides cap screwing force for the cap screwing device when screwing on the cap.

[0057] The connecting shaft 23 of the cap screwing device provides screwing torque by using the steel ball 30 and forms a quick mounting structure.

[0058] The inside structure of the sterilization cap screwing workstation is beneficial to sanitary cleaning and provides the cleaning and sterilization ball 11 necessary for performing sanitary cleaning and sterilization.

[0059] The above is an exemplary description of the present application in combination with the drawings. It is obvious that the implementation of the present application is not limited by the above-mentioned manner, and various improvements using the method concept and technical solution of the present application or direct application of the concept and technical solution of the present application to other occasions without improvement are within the protection scope of the present application.
