Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

This embodiment provides a filling machine, and fig. 2 is a schematic diagram of the filling machine according to an embodiment of the present utility model. As shown in fig. 2, the filling machine includes a filling head 1 and a capping head 2, and the capping head 2 is provided on the right side of the filling head 1, i.e., on the downstream side in the feeding direction of the containers 10. After the container 10 enters the filling machine, the filling head 1 firstly performs filling, and the cap 2 performs cap filling after the filling is completed. The container 10 in this embodiment may be a bottle, a canister, a tank, a barrel, a bag, or other packaging of various shapes and sizes, not limited to the type of container 10 shown in fig. 2. In addition, the material filled in the filling machine is not limited to liquid, but may be a solid-liquid mixture, particulate matter, or the like, and is not particularly limited herein.

Further, the filling machine further comprises a driving device 3, wherein the driving device 3 is connected with the capping head 2 and can drive the capping head 2 to move along the horizontal direction b. Since the filling time of each container 10 is longer than the capping time, the time to fill the containers 10 can complete the capping of a plurality of containers 10. For example, if the filling time of the container 10 by the filling head 1 is 30s and the capping time of the container 10 by the capping head 2 is 15s, the filling time of the filling head 1 is sufficient for the capping head 2 to cap two containers 10. The capping heads 2 are driven to move along the horizontal direction b by the driving device 3, so that one capping head 2 can correspond to a plurality of stations, and the capping heads 2 sequentially cap the containers 10 of the stations.

In the present embodiment, the capping head 2 caps the first container 10 located at the capping station when the filling head 1 performs filling. After the capping head 2 has completed capping the first container 10, the filling head 1 is still filling at this time. The drive means 3 can thus utilize the time of filling of the filling head 1 to move the capping head 2 to the second container 10 of the capping station, the capping head 2 capping the second container 10. Therefore, the number of capping heads 2 can be reduced while the filling and capping efficiency is ensured, and the equipment cost of the filling machine is further reduced.

In the present embodiment, the driving device 3 is also capable of driving the capping head 2 to move in the height direction c. On the one hand, by moving the capping head 2 in the height direction c, the capping of the container 10 can be precisely controlled. On the other hand, containers 10 of different heights can be accommodated, thereby improving the flexibility and efficiency of the filling machine.

Specifically, in the present embodiment, the driving device 3 includes a first electric cylinder 4 and a second electric cylinder 5, the first electric cylinder 4 being disposed in the horizontal direction b, and the second electric cylinder 5 being disposed in the height direction c. The accurate movement of the capping head 2 in the horizontal direction b and the height direction c is realized through the first electric cylinder 4 and the second electric cylinder 5, so that the capping accuracy is improved. In addition, the first electric cylinder 4 and the second electric cylinder 5 are convenient to electrically control, so that the degree of automation is improved.

In other embodiments of the present utility model, the driving device 3 is not limited to driving the capping head 2 by an electric cylinder, but may be driven by other types of structural devices, which are not particularly limited herein.

Further, the filling machine further comprises a feeding cap 6, which is arranged in correspondence to the right end of the first electric cylinder 4. The cover enters the cover feeding station through the slide way, and the driving device 3 drives the cover loading head 2 to move to the cover feeding station to take the cover. After the cap is taken out, the driving device 3 drives the cap loading head 2 to move to the container 10 to be capped for cap loading. The cap feeding part 6 is correspondingly arranged at one end of the first electric cylinder 4, and the cap can be provided more automatically and efficiently through the action of the first electric cylinder 4, thereby being beneficial to improving the working efficiency.

In the present embodiment, the capping head 2 is a screw capping head or a press capping head. The capping head is used to screw the cap onto the container 10 to rotate to secure the cap. The capping head ensures that the cap is securely and safely secured to the container 10, preventing leakage and contamination. The capping head is used to push the cap onto the container 10 by pressure, and is generally simple to operate and relatively fast, which is advantageous for improving the capping efficiency.

Further, the filling machine comprises a conveyor 7. The conveying device 7 in the embodiment is a complete conveyor belt which horizontally passes through the filling machine and is correspondingly arranged below the filling head 1 and the capping head 2. The conveying device 7 is arranged in the horizontal direction b for conveying the containers 10 to be filled. The capping head 2 is disposed on the downstream side of the filling head 1 in the conveying direction a of the conveying device 7. The conveyor 7 conveys the containers 10 to the filling station, and after the filling head 1 finishes filling the containers 10, the conveyor 7 conveys the filled containers 10 to the capping station. The arrangement of the capping head 2 on the downstream side of the capping head 1 helps to ensure that the container 10 can be capped in time after the completion of the filling process, thereby helping to prevent the materials in the container 10 from leaking or being contaminated by the outside, and ensuring the stability of the filling and capping process.

Further, the filling machine also comprises a load cell 8, provided in the conveyor 7 in a form corresponding to the filling head 1. In the present embodiment, the load cell 8 is electrically connected to the filling head 1 and the conveyor 7, respectively. After the container 10 is conveyed to the corresponding position of the filling head 1 by the conveying device 7, the filling head 1 fills the container 10. After the weighing sensor 8 detects that the filling weight reaches a preset value, the filling head 1 stops filling the container 10 in response to the detection signal of the weighing sensor 8, and the conveying device 7 conveys the container 10 to the capping station. The filling quantity of the container 10 can be determined through the weighing sensor 8, so that the situation of less filling or more filling is avoided, and the filling stability is ensured.

In other embodiments of the present utility model, capping may be accomplished during the transport of the container 10, as the capping time is less than the time per one station of advance of the transport container 10. When the container 10 is conveyed, the driving device 3 drives the capping head 2 to move along the conveying direction a along with the container 10 to finish capping.

In the present embodiment, the conveying device 7 is provided with a plurality of push rods 9 at intervals in the conveying direction a. The push rods 9 may divide the containers 10 on the conveyor into suitable intervals for individual handling of each container 10 during filling, capping or other procedures. By providing a space between the containers 10, the push rod 9 can prevent collision and cross interference between the containers 10. The push rod 9 ensures that each container 10 is fed to the next process in the correct sequence, thus maintaining smooth operation of the filling machine.

In the present embodiment, the number of the filling heads 1 is two, and the number of the capping heads 2 is one. Only one capping head 2 is required for each filling head 1, which saves on the equipment costs.

The whole working procedure of the filling machine in the present embodiment is as follows: the conveying device 7 steps two stations, the push rod 9 pushes the container 10 forwards along the conveying direction a to two stations, the container 10 moves to the position corresponding to the filling head 10, the filling head 10 fills the container 10, and after the weighing sensor 8 determines that the filling weight reaches a preset value, the filling head 1 stops filling. The conveyor 7 steps two stations and the push rod 9 pushes the containers 10 forward in the conveying direction a to the capping station. The driving device 3 drives the cap loading head 2 to move to the cap feeding station to take the cap, then moves to the first container 10 of the cap loading station to load the cap, and moves to the cap feeding station again to take the cap after the cap loading of the first container 10 is completed, and then moves to the second container 10 to load the cap. The filling station on the left remains in progress during the filling process. After filling and capping, the conveying device 7 steps two stations, the push rod 9 pushes the container 10 forwards to the two stations, and the container 10 leaves the filling machine.

In other embodiments of the utility model, the filling head 1 or the capping head 2 may be of other numbers, not specifically limited herein. For example, fig. 3 is a schematic view of a filling machine according to another embodiment of the present utility model, and as shown in fig. 3, the number of filling heads 1 is three, and the number of capping heads 2 is one. When the filling head 1 fills containers positioned at the filling station, the capping head 2 uses the filling time, and three filled containers positioned at the capping station are sequentially capped under the drive of the driving device 3, so that the capping requirement of the filling machine can be met by only one capping head 2, and the equipment cost is effectively reduced.

Of course, in other embodiments of the utility model, the number of capping heads 2 may not be limited to one, and for example, the filling machine may include eight filling heads 1 and two capping heads 2.

Those skilled in the art will appreciate that the specific features of the various embodiments may be adaptively split or combined. Such splitting or combining of specific technical features does not cause the technical solution to deviate from the principle of the present utility model, and therefore, the technical solution after splitting or combining falls within the protection scope of the present utility model. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
