Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of filling and sterilization, in particular to a sterilization device of a filling machine. Background Art
[0002] Filling machines are mostly used for filling liquid preparations, and they mainly include sterilizing tanks, filling equipment, transmission equipment, labeling equipment, etc. During the filling production process, the filling machine receives the feeding bottles, injects materials such as sterilizers into the bottles, and then the bottles continue to move on the transmission line to the next process, such as capping and labeling.
[0003] During the filling process of the filling machine, there are certain requirements for the filling bottles, which are reflected in the fact that the filling bottles must maintain sufficient cleanliness and be sterilized. At present, the more common sterilization method is high-temperature steam sterilization, but high-temperature steam sterilization has certain limitations. For example, it is not suitable for heat-unstable materials, such as sodium hypochlorite sterilizer, which is easy to decompose once heated.
[0004] Therefore, for the filling of heat-unstable materials, the sterilization method of the filling bottle is solvent sterilization, such as alcohol sterilization, etc. The sterilization is carried out by spraying the sterilizing agent into the filling bottle, and the filling bottle is loaded to the filling station after sterilization.
[0005] At present, cleaning mainly adopts large-scale cleaning equipment. A large number of filling bottles are cleaned by the cleaning machine, and the sterilant is poured out after cleaning. However, in the actual working process, sterilants, especially small-batch filling sterilant products (mostly trial products on the market), are cleaned by large-scale equipment. Firstly, the size of the filling bottles of small-batch products is often different from that of mature products in mass production, which is reflected in the need to replace the fixtures on the large-scale cleaning equipment. Secondly, after the large-scale cleaning equipment is started for cleaning, the amount of sterilization required is relatively large, while the small-batch customized production volume is relatively small, and the sterilant is wasted too much; finally, the number of small-batch products is small, but the variety is wide, and the frequent replacement of molds in the production process is too cumbersome.
[0006] Therefore, in the actual production process, it is very important to use a filling bottle sterilization device that is highly flexible and can meet the requirements of small batch production in the workshop. Utility Model Content
[0007] Based on the above background, the purpose of the utility model is to provide a sterilizing device for a filling machine.

[0025] The utility model has the following beneficial effects:
[0026] 1. During the working process, when multiple filling bottles on the transmission line pass through the grabbing port, the horizontal push cylinder drives the grabbing rod to move toward the grabbing port (during this process, the slide bar slides in the rectangular slide groove, and the inner slide bar slides inside the slide bar), until the clamping claw cylinder extends out of the grabbing port to grab the filling bottles on the transmission line, and then the horizontal push cylinder drives the grabbing rod to carry the filling bottles back to the original position.

[0038] Example 1
[0039] like Figure 1-5 As shown, a sterilization device of a filling machine includes a sterilization cabinet 1, and a grabbing port is opened on the rear side of the sterilization cabinet 1. During the production process, the grabbing port of the sterilization cabinet 1 is facing the transmission line (specifically, according to the existing method, a plurality of mounting seats 11 are installed on the front side wall of the sterilization cabinet 1, and the entire device is installed close to the transmission line through the mounting seats 11 to keep the grabbing port aligned with the transmission line).
[0040] The sterilizing cabinet 1 is equipped with a filling bottle grabbing mechanism. Specifically, the filling bottle grabbing mechanism includes a grabbing rod 23, and a plurality of gripping cylinders 24 are installed on the side wall of the gripping rod 23 facing the gripping port (the cylinder barrel of the gripping cylinder 24 is fixedly installed on the gripping rod 23), and a gripper 241 for grabbing the filling bottle is assembled and connected to the gripping cylinder 24.
[0041] Specifically, like the existing gripper cylinder 24 , the gripper 241 is a double-claw hand, which can be detachably mounted on the gripper cylinder 24 . Therefore, in the process of producing different products, different bottles can be grasped by replacing the grippers 241 of different sizes and models.
[0042] The claw hand 241 is provided with an arc-shaped clamping opening for conveniently clamping the filling bottle.
[0043] At the same time, both ends of the grabbing rod 23 are slidably assembled and connected with a rotating seat 22, and at the same time, the rotating seat 22 is rotatably connected to the sterilizing cabinet 1. The filling bottle grabbing mechanism also includes a motor that drives the grabbing rod 23 to rotate.
[0044] The specific method is as follows: the rotating seats 22 are respectively fixedly connected with rotating shafts, which are rotatably connected to the front and rear side walls of the sterilizing cabinet 1; the output shaft of the motor is installed on the rear rotating shaft, and the motor is installed outside the cabinet.
[0045] The rotating seat 22 is fixedly assembled with a horizontal pushing cylinder for pushing the grabbing rod 23 to move horizontally. During the grabbing process, the horizontal pushing cylinder pushes the grabbing rod 23 to move close to the grabbing port. After grabbing the filled bottle, the horizontal pushing cylinder drives the grabbing rod 23 to return to the sterilizer 1.
[0046] Specifically, rectangular slide grooves A are respectively opened on the side walls of the rotating seat 22 facing each other, and the front and rear end positions of the grabbing rod 23 are respectively fixedly connected with slide rods 31 slidably connected in the rectangular slide grooves A, and the cylinder barrel of the horizontal pushing cylinder is fixedly installed on the side wall of one side of the rotating seat 22.
[0047] At the same time, mounting seats 221 are fixedly connected to the side walls on both sides of the rotating seat 22, and the cylinder barrel of the horizontal pushing cylinder is installed on the mounting seat 221 on one side (the piston rod of the horizontal pushing cylinder is slidably connected to the mounting seat 221 and fixedly assembled on the end of the sliding rod), and an inner sliding rod B is fixedly connected to the mounting seat 221 on the other side, and the inner sliding rod B is slidably connected to the sliding rod 31 (an adaptive sliding cavity is opened on the sliding rod 31).
[0048] During the working process, when multiple filled bottles on the transmission line pass through the grabbing port position, the horizontal pushing cylinder drives the grabbing rod 23 to move toward the grabbing port position (in this process, the slide bar 31 slides in the rectangular slide groove A, and the inner slide bar B slides inside the slide bar 31), until the clamping claw cylinder 24 extends out of the grabbing port to grab the filled bottles on the transmission line, and then the horizontal pushing cylinder drives the grabbing rod 23 to carry the filled bottles to reset.
[0049] At this time, the motor drives the rotating seat 22 to rotate until the filling bottle gripped by the clamping claw cylinder 24 faces downward, waiting for spray sterilization.
[0050] After disinfection and sterilization, the motor drives the grabbing rod 23 to carry the filling bottle to reset. At this time, the horizontal pushing cylinder pushes the filling bottle to continue to extend out of the grabbing port until the clamping cylinder 24 releases the filling bottle, and then the grabbing rod 23 resets and waits for the next grabbing.
[0051] The above method can be used to grab the filling bottles to be sterilized into the sterilizer 1 in a simple and flexible manner, and spray disinfection is performed in the sterilizer 1. Firstly, the disinfectant is not easy to diffuse in the workshop, secondly, the operation is maintained in the clean environment of the sterilizer 1, and thirdly, the filling bottles of products of different sizes can be clamped. Firstly, the gripper is easy to replace, and secondly, the gripper clamping method can clamp products of different thicknesses and specifications.
[0052] Example 2
[0053] like Figure 1-5 As shown, based on the structure of Example 1, the bottom of the sterilizing cabinet 1 is equipped with a spray sterilization mechanism corresponding to the position of the clamping cylinder 24 .
[0054] Specifically, the spray sterilization mechanism includes a flat tube 4 installed at the lower end of the sterilization cabinet 1, and the top of the flat tube 4 is equipped with a plurality of nozzles 41; the liquid inlet end of the flat tube 4 is equipped with a sterilant pumping pipe 42. During the sterilization process, the disinfectant is pumped into the sterilant pumping pipe 42 and sprayed out from the nozzle 41. At this time, the above-mentioned filling bottle is in a bottle mouth downward state (at this time, the nozzle 41 is facing the inverted filling bottle), and then a large amount of high-pressure disinfectant is sprayed into the filling bottle for disinfection and sterilization.
[0055] The bottom of the sterilizing cabinet 1 is provided with a plurality of through holes for discharging waste liquid. In the actual working process, according to the existing method, a recovery tank (box) for recovering solvent is installed at the bottom of the sterilizing cabinet 1 to realize the recovery of waste liquid.
[0056] Alternatively, a waste pipe is directly connected to the bottom of the sterilizing cabinet 1 to pump out the waste liquid through the waste pipe.
[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
