[0002] The filling of pharmaceuticals such as veterinary drugs and water treatment agents requires the capping and screwing of the packaging bottles to achieve automatic packaging. Most existing capping equipment uses automatic cap dispensing. When the packaging bottles are transported by conveyor belts, the mouths of the packaging bottles scrape the caps that have been capped to achieve automatic cap dispensing. However, automatic cap dispensing often contains a silo and a loader. The overall cap dispensing path will store a large number of bottle caps. After the small-batch production of the pharmaceuticals is completed, some bottle caps need to be cleaned in time to prevent dust and other impurities from contaminating the bottle caps. This leads to the problem of insufficient applicability of such equipment when used on small-batch production lines. Utility Model Content

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model belong to the scope of protection of the embodiments of the utility model.

[0034] See also Figure 1 , Figure 1 The present invention is a schematic diagram of the electrical connection of the capping device for a filling line provided in an embodiment of the present invention, wherein the capping device comprises a cap hanging assembly 1, a material level sensor 2, a signal processing terminal 3 and an alarm 4. The material level sensor 2, the signal processing terminal 3 and the alarm 4 are connected by cables to transmit electrical signals.

[0035] See also Figure 2 , Figure 2The present invention is a schematic diagram of the structure of the capping device for the filling line provided by the embodiment of the utility model. The cap hanging assembly 1 is mounted on the conveyor belt 12 of the filling line. The cap hanging assembly 1 is used to store a preset number of bottle caps, and when the conveyor belt 12 pulls the packaging bottle 11 to be capped to move, the packaging bottle 11 is capped. Capping means hanging the bottle cap on the packaging bottle 11. The cap hanging assembly 1 can be set as a square tube with a rectangular cross-section. A limit assembly 9 is set at the lower end of the square tube. The square tube is obliquely mounted on the conveyor belt 12. The bottle cap can slide from the higher end to the lower end by its own gravity. The bottle cap stays at the mouth of the square tube 71 under the action of the limit assembly 9. When implementing the production of medicines, the medicine is filled into the packaging bottle 11 by the filling machine, and the filled packaging bottle 11 is capped under the traction of the conveyor belt 12.

[0036] The material level sensor 2 is installed on the cap hanging component 1, and the material level sensor 2 is used to output a warning signal when it detects that the storage quantity of bottle caps in the cap hanging component 1 is lower than the preset target value. The material level sensor 2 can be a mechanical micro switch, or it can be set as a through-beam photoelectric sensor, which can detect the storage quantity of bottle caps in the cap hanging component 1. It can be installed on the cap hanging component 1 by a bracket or a screw. Taking the through-beam photoelectric sensor as an example, it includes a transmitter and a receiver, which are respectively connected to a preset DC power supply, such as a 12V DC power supply, and the transmitter emits infrared light to the receiver. When the storage quantity of bottle caps in the cap hanging component 1 is higher than or equal to the preset target value, the bottle cap will block the signal transmission of the through-beam photoelectric sensor, and the receiving end cannot receive the infrared light of the transmitting end, and no warning signal is output; conversely, when the storage quantity in the cap hanging component 1 is lower than the preset target value, the bottle cap will not block the through-beam photoelectric sensor, and its receiving end receives the infrared light of the transmitting end, and then a warning signal is output.

[0037] The power supply end of the signal processing terminal 3 is connected to a preset power supply, and the input end of the signal processing terminal 3 is connected to the output end of the material level sensor 2. The signal processing terminal 3 is used to output an alarm signal when the output duration of the warning signal is greater than the preset duration. The signal processing terminal 3 can be a delay circuit board or a time relay. Taking the delay circuit board as an example, it is configured with an input end, an output end and a delay chip. The warning signal is input into the delay chip, and the continuous output time of the warning signal is measured by the delay chip. When the continuous output time reaches the preset time, the delay chip outputs an alarm signal. Of course, an adjustment knob can also be set to adjust the preset time, which is convenient for adjusting the sensitivity of the material level detection and preventing false triggering when the bottle cap moves in the hanging cover assembly 1.

[0038] The input end of the alarm 4 is connected to the output end of the signal processing terminal 3, and the alarm 4 is used to give an alarm when receiving an alarm signal. The alarm 4 can be any one of an LCD screen, a buzzer, a photoelectric alarm 4 or an audible and visual alarm 4, as long as it can warn the staff on site, and no specific limitation is made here.

[0039] The following will describe the working steps of the filling line capping device. During the filling process, the on-site staff will place the bottle caps in the cap hanging assembly 1 so that the storage quantity is greater than the preset target value. When the material level sensor 2 detects that the storage quantity of the bottle caps is large, it will not output a warning signal and maintain a real-time detection state. The packaging bottles 11 are capped under the traction of the conveyor belt 12, and the bottle cap material level gradually decreases. When the storage quantity of the bottle caps is lower than the preset target value, the material level sensor 2 outputs a warning signal to the signal processing terminal 3. The signal processing terminal 3 measures the duration of the warning signal, and outputs an alarm signal to the alarm 4 when the continuous output time reaches the preset time. The alarm 4 alarms to prompt the staff to replenish the bottle caps. When the material level of the bottle caps is greater than the preset target value, the signal processing terminal 3 can be manually reset to stop the alarm and conduct the next cycle of monitoring. Although this capping method requires staff to assist in placing the bottle caps, it will not cause a large backlog of bottle caps in the cap hanging assembly 1, can effectively prevent the contamination of the bottle caps in the intermittent production state, improve the reliability of drug production, and make the capping device more applicable in small batch production.

[0040] Exemplarily, the cap hanging assembly 1 includes a first column 5, a second column 6 and a bottle cap slide rail 7, the first column 5 is installed on the side of the conveyor belt 12 in the width direction; the second column 6 is installed on the side of the conveyor belt 12 in the width direction, and the second column 6 is arranged parallel to the first column 5; the bottle cap slide rail 7 is erected above the conveyor belt 12 through the first column 5 and the second column 6, and the bottle cap slide rail 7 is provided with a pressing plate 8 and a limiting assembly 9 at one end close to the conveyor belt 12, the pressing plate 8 is used to press the bottle cap after the packaging bottle 11 is capped, and the limiting assembly 9 is used to limit the bottle cap in the bottle cap slide rail 7.

[0041] Please continue reading Figure 2, the first column 5 and the second column 6 are installed on the support frame of the conveyor belt 12, and are used to set up the bottle cap slide rail 7. The bottle cap slide rail 7 is curved as a whole, and can be prepared by bending the square tube 71. A lower opening 72 is provided at one end close to the conveyor belt 12, and the opening of the upper opening 71 faces upward, and an upper opening 73 is provided at the other end, and the opening of the upper opening 73 faces downward. The lower opening 72 is used for the bottle cap 10 to move to avoid the air when hanging the cap, and the upper opening 73 is convenient for manual operation to place the bottle cap 10 when storing the bottle cap. The upper opening 73 and the lower opening 72 are both open trapezoidal structures. The limit assembly 9 is used to limit the position of the bottle cap located at the mouth of the pipe on the bottle cap slide rail 7. When hanging the cap, the packaging bottle 11 overcomes the limit force to complete the hanging of the cap, and the capping plate 8 presses the bottle cap that has completed the hanging of the cap, so as to facilitate the subsequent further tightening by the capping machine. The limit assembly 9 can be set as two L-shaped metal springs, and the two metal springs are installed in a mirror image relative to each other, and the whole is "┗┛". When the bottle cap is hung, it passes through the middle of the two metal springs to achieve the hanging of the cap.

[0042] Since there are anti-skid vertical lines on the outer periphery of the bottle cap, the metal spring piece is easy to cause scratches on the anti-skid vertical lines when hanging the cap, affecting the packaging quality of the product. Based on this, the limit assembly 9 is set to include a pair of mounting plates 91 and a pair of rotating parts 92, see Figure 3 , Figure 3 A schematic diagram of the structure of the bottle cap slide 7 provided in the embodiment of the utility model. A pair of mounting plates 91 are mounted at the opening position of the bottle cap slide 7 near one end of the conveyor belt 12, and are mirror-mounted along the axis of the length direction of the bottle cap slide 7; a pair of rotating members 92 can be rotatably mounted on the mounting plates 91. The mounting plates 91 can be set as a twisted sheet metal structure, which is mounted on both sides of the bottle cap slide 7 by fasteners 93, and the two mounting plates 91 are mirror-mounted; the rotating member 92 can be set as a bearing, or it can be set as a plastic wheel, which is mounted on the mounting plate 91 by bolts.

[0043] When the cap is not hung, the gap between the two rotating members 92 is smaller than the outer diameter of the bottle cap 10, achieving the limiting effect. When the cap is hung, the packaging bottle 11 moves under the traction of the conveyor belt 12, and when the mouth of the packaging bottle 11 touches the bottle cap 10, the mounting plate 91 is deformed outward, and there is rolling friction between the rotating member 92 and the bottle cap 10, which reduces the friction between the outer periphery of the bottle cap 10 and the limiting component 9 when the cap is hung, and can effectively prevent the bottle cap 10 from being scratched.

[0044] Based on the same technical concept as the capping device, the embodiment of the utility model also provides a filling line, which includes any of the above-mentioned capping devices. The filling line can be a filling production line for water treatment agents or a filling production line for fish veterinary drugs, and any application scenario with small batch intermittent production is not specifically limited here.

[0045] Although the preferred embodiments of the utility model have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
