Description

Technical Field

[0002] The MES feeding device is an automated equipment designed in combination with MES (Manufacturing Execution System) technology, mainly used to achieve accurate feeding management in the production process.

[0003] The MES feeding device uses high-precision weighing equipment and an automated control system to ensure the accuracy of the weight and proportion of each feeding. When feeding liquid materials, the liquid material causes a large impact force on the filling bottle due to the drop difference of the liquid material. Under the action of the impact force, a large dynamic load will be generated on the weighing sensor in a short period of time. This dynamic load will cause the weighing sensor to be unable to immediately and stably reflect the actual weight, thereby generating dynamic errors. In addition, the large impact force of the material feeding will also cause the weighing platform or container to vibrate and oscillate. This vibration will further affect the reading stability of the weighing sensor. Even if the liquid material has stopped feeding, due to the inertia of the system, the vibration and oscillation may still continue for a period of time, resulting in unstable weighing results, thereby affecting the weighing accuracy of the material and further reducing the feeding quality of the liquid material.

[0004] Therefore, an MES feeding device is urgently needed to solve the above problems. Utility Model Content

[0022] It should be noted here that: through the arrangement of accessories such as the production line conveyor belt 101, the storage tank 105 and the filling barrel 2, the filling of liquid materials is facilitated, and automated and precise feeding management under the control of the MES system is realized.

[0023] See also Figure 2-Figure 4 The shock-reducing assembly shown in the figure includes a mounting groove 701 provided on the inner wall of the filling tube 5, a conical shock-reducing cover 702 being slidably connected to the mounting groove 701, a plurality of shock-reducing holes 703 being provided on the side wall of the conical shock-reducing cover 702, and each shock-reducing hole 703 being arranged in a circular array. The filling tube 5 is provided with a protective assembly for protecting the conical shock-reducing cover 702 from the instantaneous impact force of the liquid, and a plurality of diversion holes 704 are provided on the side wall of the end of the filling tube 5 close to the filling barrel 2;

[0024] It should be noted here that: by setting up the impact reduction component and utilizing the multi-level flow resistance and dispersion effect, the impact force of the liquid material on the filling barrel 2 is reduced, thereby reducing the dynamic load, vibration and oscillation on the filling barrel 2, improving the weighing accuracy of the material, reducing the weighing error, and further improving the feeding quality of the liquid material.

[0025] See also Figure 2-Figure 4 The protection assembly shown in the figure includes a protection tube 801 fixedly connected to the filling tube 5 near the bottom wall of the filling barrel 2, and a protection rod 802 is slidably connected to the protection tube 801. One end of the protection rod 802 is connected to the conical impact reduction cover 702, and the other end of the protection rod 802 is located in the protection tube 801 and fixedly connected to the protection plate 803. A spring 804 is provided on the side of the protection plate 803 away from the protection rod 802, and the other end of the spring 804 is connected to the bottom wall of the protection tube 801;

[0026] It should be noted here that: by setting up the protective component and utilizing the double-layer protection effect, the instantaneous impact force of the liquid material on the conical impact reduction cover 702 is reduced, thereby ensuring the service life of the conical impact reduction cover 702.

[0027] See also Figure 4 , the protective plate 803 shown in the figure is provided with four damping holes 805 , and the protective tube 801 is filled with damping fluid, and the damping fluid passes through the four damping holes 805 when squeezed;

[0028] It should be noted here that: by setting the damping hole 805 and the damping liquid, a damping mechanism is generated, which further provides a second layer of protection against the impact force of the liquid material.

[0029] See also Figure 1 , the end of the filling pipe 5 in the figure away from the storage tank 105 is located in the filling barrel 2, and each diversion hole 704 has a height difference from the upper side wall of the filling barrel 2;

[0030] It should be noted here that: by locating the end of the filling tube 5 away from the storage tank 105 in the filling barrel 2, and setting each diversion hole 704 at a height difference from the upper side wall of the filling barrel 2, the splashing of liquid material can be avoided. What is more optimized is that a retaining ring can be installed at the open end of the filling barrel 2 to further reduce the risk of material splashing.

[0031] Working principle: When using the MES system to manage precise feeding in the production process, the production line conveyor belt 101 is first used to transport each filling bottle 102 to the bottom of the filling barrel 2 in sequence. During the actual transportation process, in order to consider the filling stability of the filling bottle 102, the filling bottle 102 will be limited. When the filling bottle 102 is transported to the bottom of the filling barrel 2, the production line conveyor belt 101 stops rotating;

[0032] The second control valve 6 is opened to allow the liquid material in the storage tank 105 to flow from the filling pipe 5 to the filling barrel 2. In the process of the liquid material flowing from the filling pipe 5, it will impact on the conical drop-shock cover 702. After the liquid material impacts the conical drop-shock cover 702, the liquid material will be blocked by the conical drop-shock cover 702, causing the liquid material to flow out from each drop-shock hole 703, thereby dispersing the liquid material, so that the liquid material flows from multiple different drop-shock holes 703 to the inner wall of the filling pipe 5, and flows along the inner wall to the bottom wall of the filling pipe 5, and finally flows from multiple diversion holes 704 to the filling barrel 2, thereby utilizing the multi-stage flow resistance and dispersion effect to reduce the impact force of the liquid material on the filling barrel 2, thereby reducing the dynamic load, vibration and oscillation of the filling barrel 2, improving the weighing accuracy of the material, reducing the weighing error, and further improving the feeding quality of the liquid material;

[0033] At the same time, when the liquid material impacts the conical shock-reducing cover 702, the protective plate 803 will be pushed to slide in the protective tube 801 through the protective rod 802 under the impact of the liquid material. As a result, the spring 804 is compressed under the sliding action of the protective plate 803, so that the spring 804 generates an elastic force. The elastic force of the spring 804 provides a first layer of protection against the impact force of the liquid material. In the process of the movement of the protective plate 803, the damping fluid in the protective tube 801 can only pass through the damping holes 805. The number of damping holes 805 is small, so that the speed at which the damping fluid passes through the protective plate 803 is slow, thereby generating a damping mechanism, further providing a second layer of protection against the impact force of the liquid material. Through the two-layer protection effect, the instantaneous impact force of the liquid material on the conical shock-reducing cover 702 is reduced, thereby ensuring the service life of the conical shock-reducing cover 702.

[0034] During the process of liquid material flowing into the filling barrel 2, the liquid material is weighed by using a weighing component. When the liquid material in the filling barrel 2 reaches the weight to be filled, the second control valve 6 is closed. At this time, the first control valve 4 can be opened to allow the weighed liquid material to flow from the filling pipe 3 into the filling bottle 102, thereby completing the filling of the liquid material and realizing automated and precise material feeding management under the control of the MES system.

[0035] Example 2

[0036] See also Figure 3This embodiment further explains Example 1. The weighing assembly shown in the figure includes a weighing hole 901 provided on the side of the L-shaped plate 103 close to the storage tank 105. Two weighing sensors 902 are provided on the bottom wall of the weighing hole 901. A fixing ring 903 is provided on the side of the two weighing sensors 902 away from the bottom wall of the weighing hole 901. The fixing ring 903 is connected to the side wall of the filling barrel 2.

[0037] It should be noted here that: by setting the weighing component, it is convenient to use the weighing sensor 902 to weigh the liquid material in the storage tank 105, thereby ensuring the accuracy of the weight and proportion of each feeding.
