Description
Technical Field
[0001] This application relates to the technical field of filling, and particularly relates to a bottle feeding device and a filling equipment. Background Art
[0002] In filling equipment, there are mainly two bottle feeding methods. One is to use wind to blow the bottle and hang the bottleneck of the bottle on the bottle feeding star wheel. The other is to use a lifting conveyor chain to support the bottom of the bottle for bottle feeding, and after the bottles are separated by a bottle feeding screw, the bottlenecks are hung on the bottle feeding star wheel.
[0003] For the first bottle feeding method, when the volume and weight of the bottle are too large, it is easy to have the situation that the bottle cannot be blown by the wind, thus affecting the bottle feeding efficiency. For the second bottle feeding method, when the heights of the bottles being fed are not the same, for example, when the height of the bottles conveyed in the front section is less than the height of the bottles conveyed in the rear section, it is necessary to adjust the height of the lower conveyor chain to ensure that the bottlenecks of the taller bottles can smoothly enter the bottle feeding star wheel. This debugging operation is cumbersome and complex, and will thus affect the operating efficiency of the equipment.
[0004] Therefore, there is an urgent need for a bottle feeding device to solve the above problems. Summary of the Utility Model

[0045] The present application provides a filling device, including a filling machine and a bottle feeding device. The bottle feeding device is used to convey empty bottles 100 to the filling machine, and the filling machine is used to fill the empty bottles 100 with liquid. This filling device can be used for filling operations of liquid beverages such as fruit juice and milk, with a high degree of automation and can meet the user's demand for filling production capacity.
[0046] As Figures 1 to 4 shown, the bottle feeding device provided by the present application includes a conveying mechanism 1, a screw bottle separating mechanism 2, a horizontal bottle feeding mechanism 3, a downward bottle feeding mechanism 4, a blowing mechanism 5, and a neck-hanging bottle feeding mechanism 6. Among them, the conveying mechanism 1 is used to convey the bottles 100, the screw bottle separating mechanism 2 is used to convey the bottles 100 on the conveying mechanism 1 one by one to the horizontal bottle feeding mechanism 3, the downward bottle feeding mechanism 4 is used to convey the bottles 100 while being able to adapt to the downward movement of the bottles 100, and the blowing mechanism 5 is used to make the bottles 100 conveyed by the downward bottle feeding mechanism 4 move downward in parallel, so that the bottle necks 102 of the bottles 100 can smoothly enter the neck-hanging bottle feeding mechanism 6. This bottle feeding device can be applicable to the bottle feeding operations of bottles 100 with different weights and different heights, without repeatedly debugging the equipment, ensuring the operation efficiency of the equipment, and being beneficial to improving the production capacity.
[0047] In another embodiment, among the mechanisms of the conveying mechanism 1, the screw bottle separating mechanism 2, the horizontal bottle feeding mechanism 3, the downward bottle feeding mechanism 4, the blowing mechanism 5, and the neck-hanging bottle feeding mechanism 6, the bottle feeding device provided by the present application may also only include the downward bottle feeding mechanism 4, the blowing mechanism 5, and the neck-hanging bottle feeding mechanism 6, and can also be applicable to the bottle feeding operations of bottles 100 with different weights and different heights, without repeatedly debugging the equipment, ensuring the operation efficiency of the equipment, and being beneficial to improving the production capacity.
[0048] In another embodiment, among the mechanisms of the conveying mechanism 1, the screw bottle separating mechanism 2, the horizontal bottle feeding mechanism 3, the downward bottle feeding mechanism 4, the blowing mechanism 5, and the neck-hanging bottle feeding mechanism 6, on the basis of including the downward bottle feeding mechanism 4, the blowing mechanism 5, and the neck-hanging bottle feeding mechanism 6, the bottle feeding device provided by the present application may further include any one or two or three of the conveying mechanism 1, the screw bottle separating mechanism 2, and the horizontal bottle feeding mechanism 3, and no further examples will be given here one by one.
[0049] The downward bottle feeding mechanism 4 includes a downward vertical frame 41, a downward bottle feeding star wheel 42 and a downward supporting plate 43. The downward bottle feeding star wheel 42 is rotatably installed on the downward vertical frame 41. The downward bottle feeding star wheel 42 has a downward accommodating groove 421 for cooperating with the bottle body 101 of the bottle 100. The downward supporting plate 43 is installed on the downward vertical frame 41 and has a downward supporting surface 431 for supporting the bottom of the bottle 100. The downward supporting surface 431 gradually extends downward along the rotation direction of the downward bottle feeding star wheel 42. When the bottle 100 moves downward under the action of the blowing mechanism 5, the downward supporting surface 431 of the downward supporting plate 43 can adapt to the downward movement of the bottle 100 and support the bottle 100, ensuring the stability of the bottle 100 transportation.
[0050] The blowing mechanism 5 includes a blowing pipe 51. The blowing pipe 51 is located above the bottle 100 accommodated in the downward accommodating groove 421. The blowing pipe 51 is used to blow air to the corresponding bottle 100, so that the corresponding bottle 100 moves downward to contact the downward supporting surface 431. By setting the blowing mechanism 5, regardless of the weight of the bottle 100 itself, it can be ensured that the bottle 100 transported by the downward bottle feeding mechanism 4 can move downward adaptively, so that the bottle neck 102 of the bottle 100 can smoothly enter the hanging neck bottle feeding mechanism 6. In this embodiment, the gas blown out by the blowing pipe 51 is clean gas to ensure the sanitary conditions of the working environment.
[0051] Furthermore, the blowing mechanism 5 further includes a column 52. The column 52 extends in the vertical direction. The blowing pipe 51 is fixed on the column 52 and is located above the bottle 100 accommodated in the downward accommodating groove 421.
[0052] The blowing pipe 51 extends along the rotation direction of the downward bottle feeding star wheel 42, and the pipe wall of the blowing pipe 51 has a plurality of blowing ports 511 facing downward. In one embodiment, the plurality of blowing ports 511 are evenly spaced on the pipe wall of the blowing pipe 51. By setting the plurality of blowing ports 511, sufficient downward force can be provided for the bottle 100 to ensure that the bottle 100 can descend to the required position. For example, the number of the blowing ports 511 can be any number such as four, five, six, seven, eight, etc. In addition, the pressure of the air blown by the blowing pipe 51 can also be adjusted to ensure that the bottle 100 can descend to the required position.
[0053] In this embodiment, the blowing pipe 51 is an arc-shaped pipe, and the center of the blowing pipe 51 is located on the rotation axis of the downward bottle feeding star wheel 42. This design can enable the blowing pipe 51 to better correspond to the bottle 100 transported by the downward bottle feeding star wheel 42, ensuring that the bottle 100 transported by the downward bottle feeding star wheel 42 can all receive the acting force of the gas blown out by the blowing pipe 51.
[0054] Further, the radius of the blowing pipe 51 is R1, the radius of the downward bottle inlet star wheel 42 is R2, and the maximum distance from the bottle body 101 of the bottle 100 accommodated in the downward accommodation groove 421 to the rotation axis of the downward bottle inlet star wheel 42 is S, where R2 ≤ R1 < S. With such a setting, it can be ensured that the gas blown out by the blowing pipe 51 can accurately blow onto the bottle 100 conveyed by the downward bottle inlet star wheel 42, ensuring that the bottle 100 can descend to the required position.
[0055] In this embodiment, both ends of the blowing pipe 51 in its extending direction are provided with air inlets 512, and the air inlets 512 are used to connect with a gas supply device. Of course, in other embodiments, the blowing pipe 51 may also have one air inlet 512, which is not limited herein.
[0056] The neck-hanging bottle inlet mechanism 6 includes a neck-hanging vertical frame 61, a neck-hanging bottle inlet star wheel 62, and a neck-hanging support plate 63. The neck-hanging bottle inlet star wheel 62 is rotatably installed on the neck-hanging vertical frame 61. The neck-hanging bottle inlet star wheel 62 has a neck accommodation groove 621 for cooperating with the bottle neck 102 of the bottle 100. The neck-hanging support plate 63 is installed on the neck-hanging vertical frame 61, and the input end of the neck-hanging support plate 63 is docked with the output end of the downward support surface 431. In actual work, the downward bottle inlet star wheel 42 conveys the bottle 100 to the position of the neck-hanging bottle inlet star wheel 62 by driving the bottle body 101 of the bottle 100. During the process of the downward bottle inlet star wheel 42 conveying the bottle 100, the blowing pipe 51 blows air downward to make the bottle 100 descend, ensuring that when the bottle 100 is docked with the neck-hanging bottle inlet star wheel 62, the bottle neck 102 of the bottle 100 can smoothly enter the neck accommodation groove 621 of the neck-hanging bottle inlet star wheel 62.
[0057] To ensure that the neck-hanging bottle inlet star wheel 62 can stably convey the bottle 100, the neck-hanging bottle inlet star wheel 62 further includes an auxiliary bottle inlet star wheel 64. The auxiliary bottle inlet star wheel 64 is rotatably installed on the neck-hanging vertical frame 61 and is located below the neck-hanging bottle inlet star wheel 62. The auxiliary bottle inlet star wheel 64 has a body accommodation groove for cooperating with the bottle body 101 of the bottle 100. With such a setting, by supporting the bottle neck 102 and the bottle body 101 of the bottle 100 up and down, it can be ensured that the bottle 100 advances smoothly during the conveying process.
[0058] The horizontal bottle inlet mechanism 3 includes a horizontal vertical frame 31, a horizontal bottle inlet star wheel 32, and a horizontal support plate 33. The horizontal bottle inlet star wheel 32 is rotatably installed on the horizontal vertical frame 31. The horizontal bottle inlet star wheel 32 has a body accommodation groove 321 for cooperating with the bottle body 101 of the bottle 100, and the body accommodation groove 321 can be docked with the downward accommodation groove 421. The horizontal support plate 33 is installed on the horizontal vertical frame 31 and is used to support the bottom of the bottle 100, and the output end of the horizontal support plate 33 is docked with the input end of the downward support plate 43.
[0059] The height of the horizontal bottle-feeding star wheel 32 is the same as that of the downward-adjusted bottle-feeding star wheel 42 to ensure that the bottles 100 conveyed by the horizontal bottle-feeding star wheel 32 can smoothly enter the downward-adjusted bottle-feeding star wheel 42.
[0060] In this embodiment, the output end of the conveying mechanism 1 is docked with the input end of the horizontal supporting plate 33. For example, the conveying mechanism 1 can be a conveyor belt mechanism or a conveying chain plate mechanism, and any mechanism that can realize the translational and directional conveying of the bottles 100 is acceptable, without limitation here. The conveying direction of the screw bottle-dividing mechanism 2 is the same as that of the conveying mechanism 1, and the screw bottle-dividing mechanism 2 is used to convey the bottles 100 on the conveying mechanism 1 one by one to the bottle body receiving groove 321 of the horizontal bottle-feeding star wheel 32.
[0061] To understand the bottle-feeding device provided by the present application, the bottle-feeding principle of the bottle-feeding device of the present application will be described below with specific examples.
[0062] When the height of the bottle neck 102 of the bottle 100 from its bottle bottom is 350 mm, the height of the bottle bottom of the bottle 100 conveyed by the conveying mechanism 1 is 240 mm, and the height of the neck-hanging bottle-feeding star wheel 62 is 540 mm. At this time, the height at which the bottle 100 can smoothly enter the neck-hanging bottle-feeding mechanism 6 should be 190 mm. By adjusting the height difference between the input end and the output end of the downward-adjusted supporting plate 43, it can be ensured that the descending height of the bottle 100 meets the requirements. That is, after the bottle 100 passes through the horizontal bottle-feeding mechanism 3 and the downward-adjusted bottle-feeding mechanism 4, the height of the bottle 100 needs to drop from 240 mm to 190 mm to ensure that after the bottle 100 comes out from the output end of the downward-adjusted bottle-feeding mechanism 4, the bottle neck 102 of the bottle 100 can smoothly enter the bottle neck receiving groove 621 of the neck-hanging bottle-feeding star wheel 62.
[0063] In other words, for the bottle-feeding device provided by the present application, the height difference between the input end and the output end of the downward-adjusted supporting surface 431 of the downward-adjusted supporting plate 43 can be adaptively adjusted according to the height of the bottle bottom of the bottle 100 conveyed by the conveying mechanism 1 in the equipment, the height of the neck-hanging bottle-feeding star wheel 62, and the height of the bottle 100 itself, so as to meet the downward adjustment requirements of the bottle 100. It can be understood that the method of adjusting the height difference between the input end and the output end of the downward-adjusted supporting surface 431 of the downward-adjusted supporting plate 43 can be to replace the downward-adjusted supporting plate 43 with a downward-adjusted supporting surface 431 having different height differences, or to design the downward-adjusted supporting surface 431 of the downward-adjusted supporting plate 43 as a structure with an adjustable height difference, and no further examples will be given here.
[0064] The above shows and describes the basic principles, main features, and advantages of the present application. Those skilled in the art of this industry should understand that the above embodiments do not limit the present application in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present application.
