Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filling production line technology, specifically relating to a baby bottle cap assembly equipment. Background Technology
[0002] Currently, all packaged dairy products are packaged using automated filling production lines. During the assembly process, the bottle cap and bottle body are installed separately because the bottle body involves the bottling of materials from the preceding process. After quantitative bottling, the cap is installed and sealed, and then pasteurization is carried out before random sampling and inspection to complete the assembly.
[0003] In existing filling equipment, bottle cap assembly equipment is a post-assembly mechanical structure, functionally divided into assembly and feeding parts. In most existing technologies, the bottle body is positioned and transferred separately on a rotary conveyor mechanism, and the bottle cap is pressed onto the bottle body for assembly during the transfer process. However, this method requires a separate device to be set up on the existing conveyor belt, and the bottle cap feeding method still requires manual placement. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a bottle cap assembly device that achieves a more efficient bottle body and cap assembly effect by using an external feeding and assembly mechanism on the existing conveyor belt-based dairy product filling line.
[0005] The technical solution adopted in this utility model is as follows:
[0006] In the first aspect, this utility model provides a bottle cap assembly device, including a conveyor belt for transporting the bottle body and a bottle cap assembly mechanism disposed on the conveyor belt, wherein the bottle cap is placed on the bottle body by a material feeding mechanism and rotated and assembled by the bottle cap assembly mechanism.
[0007] The material feeding mechanism includes a vertical elevator set on one side of the conveyor belt. The top of the elevator is provided with a material chute for guiding bottle caps into the conveyor belt. The end of the material chute extending toward the conveyor belt has a feeding hopper. The feeding hopper has a feeding port for the bottle caps to fall out and contact the bottle opening on the conveyor belt. The bottle cap assembly mechanism is set behind the feeding hopper with the conveyor belt transmission direction as a reference.
[0008] In conjunction with the first aspect, the present invention provides a first embodiment of the first aspect, wherein the hopper has a limiting member that is powered by an electrically controlled power mechanism, and the bottle cap is controlled by the limiting member to intermittently fall into the opening of the bottle body at the hopper.
[0009] It should be noted that after the bottle caps are lifted to a certain height by the elevator, they are guided by the material chute and fall under gravity, where they are stabilized by limiting components near the hopper close to the conveyor belt. At this time, the bottle caps near the discharge port are constantly pushed by several bottle caps behind them, thus exhibiting a tendency to move. The limiting components are controlled by an electrically powered mechanism, which releases / limits the caps according to a set time interval. Based on the actual drop speed of the bottle caps at the discharge port and the frequency and speed of the bottle body passing through, each bottle cap is ensured to contact the bottle body.
[0010] In conjunction with the first embodiment of the first aspect, this utility model provides a second embodiment of the first aspect, wherein the limiting member is a clamp driven by a cylinder.
[0011] In conjunction with the first embodiment of the first aspect, this utility model provides a third embodiment of the first aspect, wherein the limiting member is a roller assembly driven by a motor.
[0012] The so-called roller assembly refers to a hopper with a channel for a single bottle cap to pass through. On both sides of the channel, there is a set of rollers that can conform to the surface of the bottle cap. The two rollers rotate in opposite directions, which can restrain the bottle cap after it falls into the channel and throw the bottle cap outward when the rollers roll.
[0013] In conjunction with the first embodiment of the first aspect, this utility model provides a fourth embodiment of the first aspect, wherein the limiting member is a pressure plate disposed on the hopper and movably connected to the hopper, and a gap is formed between the pressure plate and the discharge port that is smaller than the thickness of the bottle cap. The hopper is also provided with a spring that provides a pushing force to the pressure plate to always keep the gap smaller than the thickness of the bottle cap. The bottle cap entering the hopper is limited and fixed by the gap of the pressure plate. The part of the bottle body moving on the conveyor belt that contacts the bottle cap falling out of the discharge port provides the bottle cap with a force that overcomes the elastic limiting force of the pressure plate and drives the bottle cap to fall out of the hopper.
[0014] In conjunction with the first aspect or several embodiments of the first aspect, this utility model provides a fifth embodiment of the first aspect, wherein the elevator and the conveyor belt are arranged on two parallel cabinet frames, and a material trough for placing a number of bottle caps is provided at the bottom of one side of the elevator frame, and the upper part of the material slide is connected to the upper discharge port of the elevator through a discharge frame.
[0015] In conjunction with the fifth embodiment of the first aspect, this utility model provides a sixth embodiment of the first aspect, wherein the conveyor belt is provided with a gantry frame fixedly connected to the cabinet frame, the gantry frame is provided with a guide rail whose length direction is parallel to the conveyor belt transmission direction, and the guide rail is provided with a belt mechanism driven by a motor.
[0016] In conjunction with the sixth embodiment of the first aspect, this utility model provides a seventh embodiment of the first aspect, wherein the bottle cap assembly mechanism includes a capping assembly and a screwing assembly, the gantry frame is provided with a lifting frame and a horizontal frame parallel to the conveyor belt, the capping assembly is disposed on the lifting frame, and the screwing assembly is disposed on the horizontal frame.
[0017] In conjunction with the seventh embodiment of the first aspect, this utility model provides an eighth embodiment of the first aspect, wherein the pressure cap assembly includes a pneumatic telescopic cylinder and a pressure block disposed at the end of the telescopic cylinder.
[0018] In conjunction with the seventh embodiment of the first aspect, this utility model provides a ninth embodiment of the first aspect, wherein the horizontal frame includes two parallel profile rods fixed to both sides of the portal frame by bolts, and the screwing assembly includes two rotary motors respectively disposed on the two profile rods, the rotary motors being provided with wheels, and the gap between the two wheels being smaller than the outer diameter of the bottle cap.
[0019] The beneficial effects of this utility model are as follows:
[0020] This utility model uses a conveyor belt and an elevator to lift several bottle caps to a certain height, which are then screened and fall from the material chute. This utilizes the material's own gravity to create an automatic material dropping effect. By setting limiting components to restrict the movement of the bottle body, the bottle caps are pre-installed in accordance with the bottle body, thus improving efficiency.

[0034] Example 1:
[0035] This utility model provides a bottle cap assembly device, including a conveyor belt for transporting the bottle body and a bottle cap assembly mechanism disposed on the conveyor belt. The bottle cap is placed on the bottle body by a feeding mechanism and then rotated and assembled by the bottle cap assembly mechanism.
[0036] The material feeding mechanism includes a vertical elevator 2 set on one side of the conveyor belt. The top of the elevator 2 is provided with a material chute 4 for guiding bottle caps into the conveyor belt 11. The end of the material chute 4 extending towards the conveyor belt has a feeding hopper 9. The feeding hopper 9 has a feeding port for the bottle caps to fall out and contact the bottle opening on the conveyor belt 11. The bottle cap assembly mechanism is set on the rear side of the feeding hopper 9, with the conveyor belt 11 as a reference.
[0037] Furthermore, a specific embodiment is provided, wherein the conveyor belt 11 is a stable conveying device for receiving bottles containing dairy products. It typically uses several hinged rigid plates as the conveyor belt to provide good stability. The conveyor belt 11 can be directly configured according to the overall requirements of the bottling production line, using a standardized conveyor belt 11 specification. The elevator 2 is then positioned on one side of the conveyor belt 11, while the bottle cap assembly mechanism can be directly mounted on the conveyor belt 11 via a fixed frame. The conveyor belt 11 is used to move the bottles at intervals to the bottle cap assembly mechanism for assembly.
[0038] Among them, the elevator 2 is a vertical belt conveyor with several baskets or partitions on the belt, which can lift several scattered bottle caps in the material trough 6 on one side of the elevator 2 upward. The material is carried to the upper part of the basket or partition, so that it has a higher height than the plane of the conveyor belt 11, which makes it convenient for the bottle caps to slide down from the opening of the material slide 4 at the top of the elevator 2, thus having initial power.
[0039] The top of the elevator 2 has a guiding ramp. All the bottle caps lifted to the top by the basket or partition will come into contact with the ramp and be guided obliquely to the connection between the material chute 4 and the elevator 2. Then, the individual bottle caps fall from the material chute 4 in sequence and finally slide onto the conveyor belt 11.
[0040] Reference Figures 1-5In this embodiment, the elevator 2 and the conveyor belt 11 are structures on two side-by-side cabinet frames 1. The elevator 2 is a vertical structure, and the material chute 4 is an arc-shaped hollow chute structure, including four arc-shaped extended guide rods and several support rings evenly spaced between the four guide rods. A discharge rack 3 is provided on one side of the upper part of the elevator 2. The discharge rack 3 is used to guide bottle caps sliding down from the top of the elevator 2 into the material chute 4. The discharge rack 3 is formed by two metal plates fastened together, with the fastening gap slightly larger than the thickness of the bottle cap. Through the conical inner guide channel, multiple bottle caps are restricted to enter the material chute 4 individually, and the size of the material chute 4 is just large enough to accommodate one bottle cap at a time.
[0041] As not shown in the diagram, at least two infrared sensors are installed on the material chute 4 near the discharge rack 3. These infrared sensors are mounted on the support ring and are used to detect the presence and count of bottle caps at their designated locations. Once the infrared sensors detect that no bottle caps have passed through within a certain period, an alarm will be triggered. The operator can then check whether the material trough 6 below the elevator 2 is empty or whether bottle caps are blocking the inlet of the discharge rack 3.
[0042] Furthermore, referring to Figure 4 A gantry frame 5 is installed on the conveyor belt 11. Symmetrical guide rails 8 are located on both sides of the lower part of the gantry frame 5, close to the sides of the conveyor belt 11. The guide rails 8 also have a conveyor belt structure, with their belt plane perpendicular to the belt plane of the conveyor belt 11. The end of the guide rail 8 facing the bottle entry is tapered, meaning that when two guide rails 8 are combined, they form a tapered opening at the bottle entry point, facilitating the guidance of an unlimited number of bottles into the middle of the guide rail 8, ultimately achieving the effect of a single bottle passing through the gantry frame 5. The gantry frame 5 and the cabinet frame 1 are connected and formed using the same profile. One end of the guide rail 8 is fixed to the gantry frame 5 with bolts, and the other end is fixed to the profiles on both sides of the conveyor belt 11 with fasteners.
[0043] Reference Figure 4 The gantry frame 5 is also provided with a horizontal frame 12 extending to the rear side in the direction of conveyor belt 11, and a lifting frame 10 is provided inside the gantry frame 5.
[0044] As shown in the figure, the horizontal frame 12 includes two parallel profile rods bolted to both sides of the portal frame 5. The screwing assembly includes two rotary motors respectively mounted on the two profile rods. Each rotary motor has a rotating wheel, and the gap between the two rotating wheels is smaller than the outer diameter of the bottle cap. Specifically, a push cylinder is also provided between the rotary motor and the profile rod. By pushing the cylinder on one or both sides, the soft rotating wheel on the rotary motor can contact the bottle cap that is placed on the bottle body. The two rotating wheels rotate in opposite directions to screw and fix the bottle cap to the bottle body.
[0045] A capping assembly is also provided on the lifting frame 10. The capping assembly includes a pneumatic telescopic cylinder and a pressure block located at the end of the telescopic cylinder. After the bottle body is restricted by the guide rail 8 to enter the corresponding installation position of the gantry frame 5, the bottle cap falls onto the bottle body. Then, the pressure block of the capping assembly presses the bottle cap down from the top and maintains a certain downward pressure. At this time, the rotating wheels clamping on both sides tighten the bottle cap downward and fix it, thus completing the installation of a single bottle body and bottle cap. Then, the pressure block is lifted up to allow the next bottle body to enter the corresponding installation position and the above operation is repeated.
[0046] Furthermore, referring to Figure 5 A corner bracket 7 is fixed on one side of the gantry frame 5 to connect to the lower end of the material slide 4, guiding the bottle caps sliding down from the material slide 4 to the conveyor belt 11. The other end of the corner bracket 7 is connected to a hopper 9 structure. The hopper 9 has a discharge port for the bottle caps to fall out and contact the bottle opening on the conveyor belt 11. The bottle cap assembly mechanism is located behind the hopper 9, with the conveyor belt 11's transmission direction as a reference. A limiting element is provided at the discharge port of the hopper 9. This limiting element is a pressure plate installed on and movably connected to the hopper 9. A gap smaller than the bottle cap thickness is formed between the pressure plate and the discharge port. The hopper 9 also has a spring that provides a pushing force to the pressure plate to always maintain a gap smaller than the bottle cap thickness. The bottle caps entering the hopper 9 are held in place by the gap of the pressure plate. The movement of the bottle body on the conveyor belt 11, contacting the part of the bottle cap that falls out of the discharge port, provides the bottle cap with a force that overcomes the elastic limiting force of the pressure plate, causing the bottle cap to fall out of the hopper 9.
[0047] In other words, as the conveyor belt 11 enters the bottle body within the guide rail 8, upon reaching the discharge hopper 9, a portion of the bottle cap's edge, protruding at an angle, contacts the opening edge of the moving bottle body. With the force of the moving bottle body, the bottle cap is pulled diagonally downwards out of the discharge port. At this point, the transmitted force is greater than the elastic limiting force of the pressure plate, allowing the bottle cap to be pulled out smoothly. Furthermore, because the bottle body opening edge itself has external threads, and the bottle cap contact portion also has internal threads, after the bottle cap is pulled out of the discharge hopper 9, it can smoothly fall onto the opening of the bottle body, thus completing the pre-installation of the bottle cap and bottle body.
[0048] This utility model is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of this utility model. The specific embodiments described above should not be construed as limiting the scope of protection of this utility model. The scope of protection of this utility model shall be determined by the claims, and the description can be used to interpret the claims.
