DETAILED DESCRIPTION

[0028] like Figure 1-5 As shown, the present invention is further described in detail below. The embodiments of the present invention are given for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0029] like Figure 1-5 As shown, the technical scheme of the present invention provides a feeding and conveying device and feeding and conveying method for counting rubber rings, comprising a telescopic feeding assembly 1, a vibrating material tray 2 and a feeding assembly arranged in sequence along the material conveying direction, and a leveling assembly 6 for spreading the material is arranged on the feeding assembly. The feeding and conveying device of this scheme feeds when counting rubber rings, and the material is conveyed into the telescopic feeding assembly 1 by the hoist, and then evenly conveyed into the vibrating material tray 2 by the telescopic feeding assembly 1, and then conveyed to the feeding assembly by the vibrating material tray 2, and then conveyed to the feeding assembly by the vibrating material tray 2, and the leveling assembly 6 on the feeding assembly spreads the material on the feeding assembly, and falls from the end of the feeding assembly, and the counting and sub-packaging processing are realized by the subsequent device.

[0030] The telescopic feeding assembly 1 includes a feeding enclosure 11, a belt conveyor 12 installed on the feeding enclosure 11, and a pneumatic telescopic mechanism 13 for driving the feeding enclosure 11 to move. The feeding enclosure 11 and the end of the belt conveyor 12 form a feeding outlet 14. When the pneumatic telescopic mechanism 13 drives the feeding enclosure 11 to move, the feeding outlet 14 switches its position above the vibrating material tray 2.

[0031] In the above scheme, the elevator directly pours the material onto the belt conveyor 12 and limits it through the feeding enclosure 11. When the belt conveyor 12 is running, the material enters the vibrating tray 2 through the feeding outlet 14. The feeding assembly includes a coarse feeding conveying channel 3 and a fine feeding conveying channel 4. The vibrating tray 2 feeds the coarse feeding conveying channel 3 and the fine feeding conveying channel 4 at the same time. The pneumatic telescopic mechanism 13 can make the belt conveyor 12 move above the vibrating tray 2, thereby ensuring that the material is evenly distributed in the vibrating tray 2, and ensuring that there is material in both channels.

[0032] The vibrating tray 2 includes a coarse feeding vibrating tray and a fine feeding vibrating tray, between which a transition plate 21 is arranged, and the coarse feeding vibrating tray and the fine feeding vibrating tray respectively correspond to the coarse feeding conveying channel 3 and the fine feeding conveying channel 4. The interior of the vibrating tray 2 is made of rice-grain stainless steel to prevent the surface from sticking. By setting the transition plate 21, and the shape of the transition plate 21 is trapezoidal, it is ensured that when feeding, after the materials are collected in any vibrating tray, they can be distributed to another vibrating tray to avoid the risk of stacking.

[0033] The material leveling assembly 6 is provided in two groups and is respectively provided on the front and rear sides of the material feeding plate 43. The material leveling assembly 6 includes a mounting bracket 61, an electric brush 62 provided on the mounting bracket 61, and a driving cylinder 63 for driving the electric brush 62 to rise and fall. The electric brush 62 is provided across the coarse material feeding conveying channel 3 and the fine material feeding conveying channel 4.

[0034] In the above scheme, the electric brush 62 can rotate under the drive of the motor, so as to make the passing materials flat, and the height of the electric brush 62 can be adjusted. The purpose of adjusting the height is to adjust the distance between the electric brush 62 and the channel surface to adapt to the material leveling of rubber rings of different specifications. Two sets of front and rear material leveling components 6 are set to ensure that the material that is not leveled in the front section is further leveled and leveled in the rear section to avoid material stacking and improve counting accuracy.

[0035] The width of the coarse feeding conveying channel 3 is wider than that of the fine feeding conveying channel 4. The coarse feeding conveying channel 3 and the fine feeding conveying channel 4 are respectively provided with a coarse feeding cut-off gate 31 and a fine feeding cut-off gate 46 at the discharge ends. The coarse feeding conveying channel 3 and the fine feeding conveying channel 4 convey materials simultaneously at the beginning. When the predetermined amount is reached, the coarse feeding cut-off gate 31 is closed, the coarse feeding conveying channel 3 stops feeding, and then the remaining materials are supplemented through the fine feeding conveying channel 4 until the target amount is reached, and the fine feeding cut-off gate 46 is closed. The two channels operate independently, and the controllability is higher.

[0036] A feeding plate 43 for adjusting the width of the fine feeding conveying channel 4 is rotatably provided in the fine feeding conveying channel 4, and the materials are arranged in a single row after passing through the feeding plate 43; a return port 42 is provided on one side of the fine feeding conveying channel 4, a return chute 5 is provided at the return port 42, and the end of the feeding plate 43 is provided with a guide block 41 facing the return port 42. A wedge-shaped guide block 41 is provided in the fine feeding conveying channel 4 near the feeding plate 43, the inclined surface of the guide block 41 faces the inlet of the fine feeding conveying channel 4, and the guide block 41 and the feeding plate 43 are provided on the same side.

[0037] In the above scheme, the feeding plate 43 is arranged on one side of the fine feeding conveying channel 4 and is located on the side of the fine feeding conveying channel 4 away from the return port 42. The feeding plate 43 is driven by a motor. In the initial feeding stage, the feeding plate 43 does not rotate, and the fine feeding conveying channel 4 is open. In the feeding stage, the motor drives the feeding plate 43 to rotate a certain angle to allow the materials to pass in a single file. The rotation angle is determined by materials of different specifications. The function of the guide block 41 is to prevent the material from being stuck behind the feeding plate 43, and after the feeding is completed, the material can also be guided to the return chute 5.

[0038] The blowing structure includes an air path channel arranged in the feeding plate 43 and an air inlet pipe 44 externally connected to the feeding plate 43. The feeding plate 43 is provided with an air outlet hole 45 connected to the air path channel. The air outlet holes 45 are arranged from top to bottom in a plurality and face the return port 42. After the feeding is completed, the motor drives the feeding plate 43 to rotate to close the fine feeding conveying channel 4. The material is intercepted and enters the return port 42, and then enters the return chute 5 through the return port 42, and is transported to the elevator storage hopper by the return chute 5, and then re-transported. The setting of the blowing structure can blow the material into the return chute 5 to avoid material blockage. When returning the material, high-pressure gas is introduced into the air path channel through the air inlet pipe 44, and the high-pressure gas is discharged from the air outlet to blow the material. The blowing structure is integrated on the material feeding plate 43, which simplifies the structure and saves costs, so that the material feeding plate 43 not only has the function of controlling the size of the channel, but also has the function of returning the material.

[0039] When the rubber ring feeding and conveying device of this scheme is used in a counting machine, the counting process is as follows Figure 6 As shown in the figure, taking the counting of 100 pieces in a single package as an example, the counting method is:

[0040] Manual feeding into the hoist storage hopper, the hoist feeds the material to the belt conveyor 12 of the telescopic feeding assembly 1. Then the pneumatic telescopic mechanism 13 drives the belt conveyor 12 to switch the feeding back and forth between the coarse feeding vibration plate and the fine feeding vibration plate, and detects the material level through the photoelectric detection. Initially, the telescopic feeding assembly 1 first feeds the corresponding area of ​​the coarse feeding conveying channel 3.

[0041] The materials entering the coarse feeding conveying channel 3 and the fine feeding conveying channel 4 are spread out in the channels through the material leveling assembly 6, and the two channels simultaneously convey materials to the camera counting module 7. When the number of materials remembered by the camera counting module 7 is A1 (such as 95), the coarse feeding material cut-off gate 31 is closed, and the coarse feeding conveying channel 3 stops feeding; the fine feeding vibration plate switches from continuous vibration to pulse vibration, and the feeding plate 43 in the fine feeding conveying channel 4 adjusts the channel width to allow the materials to pass through in a single file for feeding (replenishment of 5). When the number of materials remembered by the camera counting module 7 reaches the target value A2 (100), the feeding plate 43 rotates until the channel is closed, and the excess materials are blown into the return chute 5 through the blowing structure.

[0042] The counted materials are stored in the discharge hopper 8, which has two hoppers for storing materials for the coarse feeding conveying channel 3 and the fine feeding conveying channel 4, and is equipped with an electric gate. After the counting is completed, the sum of the two hoppers is the target value A2, indicating that the counting is qualified, and then the two hoppers discharge materials at the same time, and convey them to the bag feeding packaging machine for packaging through the forward and reverse belt conveyors. When the sum of the two hoppers is greater than the target value A2, it means that the refilling exceeds the standard, and the materials in the hopper corresponding to the fine feeding conveying channel 4 are discharged, and the forward and reverse belt conveyors discharge the materials into the elevator hopper, and refill the materials through the fine feeding conveying channel 4 until the sum of the two hoppers is equal to the target value A2.

[0043] The camera counting module includes a counting camera and a light source component. The camera takes pictures and transmits them back to the upper computer unit for counting. The module can adopt a commonly used counting module in the prior art.

[0044] This solution can realize material feeding by setting up a coarse feeding conveying channel 3 and a fine feeding conveying channel 4, and can also carry out fine material replenishment to ensure counting accuracy. The replenishment plate 43 set in the fine feeding conveying channel 4 is also equipped with a blowing structure, which can flexibly adjust the channel width and return the excess material after replenishment. The return chute 5 realizes the automatic return of materials without manual return, reduces manual intervention, and improves counting efficiency. For rubber ring materials, the vibrating material tray 2 is set to a rice grain board material to prevent the material from sticking to the vibrating material tray 2.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
