Description

Technical Field

[0001] This utility model relates to the field of automation equipment, and in particular to a precise material counting device. Background Technology

[0002] Existing technologies employ a multi-channel conveying device with varying flow rates, combined with point-counting cameras. When the amount of material being conveyed approaches a preset value, the high-flow-rate channel is shut down, leaving only the low-flow-rate channel operational. This achieves precise material conveying and prevents the conveyed material from exceeding the preset value.

[0003] However, the above-mentioned technologies have at least the following technical problems:

[0004] Materials running on conveyor systems may be stacked, causing counting cameras to easily identify multiple stacked materials as a single item, thus affecting the counting accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a precise material counting device to solve the problem that materials may be piled up on the conveying device in the prior art, leading to inaccurate counting.

[0006] The technical solution of this utility model is: a precise material counting device, including a feeding mechanism and a conveying component;

[0007] The conveying assembly is inclined and has a loading end at the top and a unloading end at the bottom; the feeding mechanism is located at the loading end and is used to supply multiple materials to the conveying assembly.

[0008] The conveying assembly is provided with a material straightening mechanism at the feeding end. The material straightening mechanism includes a material straightening roller with a horizontal axis. The outer surface of the material straightening roller can abut against the materials stacked on the conveying assembly, so that any material passing through the material straightening roller does not have an overlapping vertical projection with other materials.

[0009] Preferably, a bracket is fixed on the conveying assembly, and the material roller is rotatably connected to the bracket, so that the material roller is suspended above the conveying assembly, and the minimum distance between the material roller and the conveying assembly is not greater than the minimum height of two stacked materials.

[0010] Preferably, the material roller is not powered to the support.

[0011] Preferably, the material straightening mechanism includes a material straightening driver, and the material straightening roller is directly or via a transmission connection to the material straightening driver, and the material straightening driver is capable of driving the material straightening roller to rotate.

[0012] Preferably, under the drive of the material straightening driver, the movement direction of the point on the material straightening roller closest to the conveying component is opposite to the movement direction of the conveying component.

[0013] Preferably, the conveying assembly includes a first conveying channel and a second conveying channel arranged in parallel, each of the first and second conveying channels having an independent driving device, and the second conveying channel having a width smaller than that of the first conveying channel; and the conveying assembly is configured in multiple ways at different heights.

[0014] Preferably, a visual counting device and a feeding plate are provided at the feeding end. The feeding plate is opened and closed by the feeding driver, so that the material falls from the conveying component or remains in the conveying component.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] This application includes a material-aligning mechanism at the feeding end of the conveying component, which can contact materials stacked on top of other materials on the conveying component, causing the materials to detach from the other materials. This prevents the visual counting device from identifying multiple stacked materials as a single item, thus affecting the counting effect. Attached Figure Description

Detailed Implementation

[0024] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] The present invention will be further described in detail below with reference to specific embodiments:

[0026] like Figure 1 and Figure 2 As shown, a precision material counting device includes a feeding mechanism 1, a conveying component 2, and a discharging mechanism 3.

[0027] The conveying assembly 2 is inclined and has a loading end at the top and a unloading end at the bottom. The feeding mechanism 1 is located at the loading end, and the unloading mechanism 3 is located at the unloading end. The feeding mechanism 1 includes a hopper 11, a hoist 12, and a vibrating feeding table 13, which are used to supply multiple materials to the conveying assembly 2.

[0028] The conveying assembly 2 is used to convey the material output from the feeding mechanism 1 to the unloading mechanism 3 in a preset quantity. The conveying assembly 2 is equipped with a visual counting device 5 at the unloading end, which can count the quantity of material conveyed on the conveying assembly 2.

[0029] To prevent multiple materials from stacking together on the conveying component 2 during the feeding process of the feeding mechanism 1, which would cause the visual counting device 5 to identify multiple stacked materials as a single one and affect the counting effect, this application provides a material straightening mechanism 4 at the feeding end of the conveying component 2.

[0030] The material handling mechanism 4 includes a material handling roller 41, which has an axis arranged in a horizontal direction, and the outer surface of the material handling roller 41 can come into contact with the material stacked on top of other materials on the conveying assembly 2, so that the material falls off the other materials.

[0031] Specifically, in combination Figure 3 As shown, the conveying assembly 2 includes a base, on which a bracket 43 is fixed upwards. The bracket 43 is rotatably connected to both ends of the material-stabilizing roller 41, so that the material-stabilizing roller 41 is suspended above the conveying assembly 2. Furthermore, in order to achieve the effect of the material-stabilizing roller 41 peeling stacked materials from the material below, the minimum distance between the lower edge of the material-stabilizing roller 41 and the conveying assembly 2 is not greater than the minimum height of two stacked materials.

[0032] In some embodiments of this application, the material roller 41 and the bracket 43 are connected only by bearings, and the material roller 41 is not connected to an external drive device.

[0033] In a preferred embodiment of this application, the material straightening mechanism 4 is further provided with a material straightening driver 42, and the material straightening roller 41 is directly or through a transmission connection with the material straightening driver 42, so that the material straightening driver 42 can drive the material straightening roller 41 to rotate around the axis of the material straightening roller 41. Further, as... Figure 4 As shown, the movement direction of the closest point on the material-forming roller 41 to the conveying component 2 is opposite to the movement direction of the conveying component 2, which can bounce off materials stacked on other materials and achieve a better material-forming effect.

[0034] In addition, such as Figure 1 As shown, the conveying assembly 2 includes a first conveying channel 21 and a second conveying channel 22 arranged in parallel. Both the first and second conveying channels 21 and 22 have independent drive devices, and the second conveying channel 22 has a smaller width than the first conveying channel 21. This allows the second conveying channel 22 to operate independently and convey materials towards the unloading mechanism 3 at a smaller flow rate, thereby enabling more precise control over the quantity of materials entering the unloading mechanism 3. Furthermore, multiple conveying assemblies 2 are configured at different heights. As the quantity of material passing through the visual counting device 5 gradually approaches a preset value, the upper and middle conveying assemblies 2 are sequentially shut down, leaving only the lower conveying assembly 2 operational. This results in a slower and more controlled flow of material into the unloading mechanism 3, further enhancing the control over the quantity of material entering the unloading mechanism 3.

[0035] In this embodiment, such as Figure 5 As shown, a feeding plate 23 is provided at the corresponding feeding end. The feeding plate 23 is opened and closed by the feeding driver 24, so that the material falls from or remains in the conveying assembly 2. When the material passing through the visual counting device 5 has not reached the preset value, the feeding plate 23 is closed, and the material remains on the conveying assembly 2. When the material passing through the visual counting device 5 reaches the preset value, the feeding plate 23 is opened, and the material falls from the conveying assembly 2 into the feeding mechanism 3.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
