Description

Technical Field

[0001] This utility model relates to the field of workpiece feeding machinery technology, specifically to a novel counting, sorting and unloading device. Background Technology

[0002] With the increasing demand for packaging materials such as granules, flakes, capsules, and toy building blocks, more and more feeding machines are appearing on the market. A feeding machine generally includes a vibration screening mechanism, a vision inspection mechanism, and a counting and sorting feeding device. The material is vibrated and screened by the vibration screening mechanism and then conveyed to the vision inspection mechanism. The vision inspection mechanism collects and detects the image information of the material. During this process, the material is slowly conveyed to the counting and sorting feeding device. The counting and sorting feeding device tracks, counts, and sorts the material. Finally, qualified material is placed into the storage hopper of the circulation line by the counting and sorting feeding device, while unqualified material is rejected by the counting and sorting feeding device.

[0003] In the current market, counting and sorting feeding devices generally have an upper-level rotating paddle mechanism and a lower-level rotating paddle mechanism. A waste discharge port is located at the rear of the device, connected to the first-level paddle drive mechanism. After detection by a vision inspection mechanism and tracking and counting by the counting and sorting feeding device, the device determines whether the material is qualified. If the material is unqualified, the first-level paddle drive mechanism will rotate the paddle backward to remove the unqualified material from the waste discharge port. During the paddle rotation process, unqualified material can easily get stuck in the gap between the first-level paddle and the front plate, preventing proper removal. Furthermore, after the counting and sorting feeding device stops working, when resetting and rotating the paddle in reverse, the remaining material on the paddle can easily get stuck in the gap between the paddle and the front plate, preventing proper reset. Both of these phenomena affect the stable operation of the counting and sorting feeding device. Utility Model Content

[0004] To address the existing problems, this utility model proposes a novel counting, sorting, and unloading device that effectively avoids material jamming and ensures stable operation of the device.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A novel counting, sorting, and unloading device includes a photoelectric detection mechanism, a dual-channel unloading cavity, and an upper-level paddle rotating mechanism and a lower-level paddle rotating mechanism located on both sides of the dual-channel unloading cavity. The photoelectric detection mechanism is located at the inlet of the dual-channel unloading cavity. A cleaning chamber connected to the upper-level paddle rotating mechanism and a waste discharge chamber connected to the lower-level paddle rotating mechanism are provided at the rear of the dual-channel unloading cavity.

[0007] The dual-channel feeding cavity includes a middle plate, side plates symmetrically distributed on both sides of the middle plate, and a front connecting structure and a rear connecting plate fixed to the front and rear of the middle plate and side plates. The front sides of the middle plate and the two side plates are respectively provided with arc-shaped structures matching the rotation path of the paddle at the corresponding positions of the upper-level paddle rotation mechanism and the lower-level paddle rotation mechanism. The front connecting structure includes a malleable upper front plate and a lower front plate. Multiple arc-shaped pressure strips are provided on the outer side wall of the front connecting structure. The arc-shaped pressure strips fix the upper front plate and the lower front plate to the arc-shaped structure of the middle plate and the two side plates, so that the upper front plate and the lower front plate both form arc-shaped plates.

[0008] Preferably, the front connection structure further includes an upper connecting plate fixed above the upper front plate, a middle connecting plate fixed between the upper and lower front plates, and a lower connecting plate fixed below the lower front plate. The bottom end of the upper connecting plate and the top end of the middle connecting plate press the upper and lower ends of the upper front plate onto the upper arc-shaped structure of the middle plate and the two side plates. The bottom end of the middle connecting plate and the top end of the lower connecting plate press the upper and lower ends of the lower front plate onto the lower arc-shaped structure of the middle plate and the two side plates. The upper, middle, and lower arc-shaped pressure strips are fastened to the middle plate and the two side plates by fasteners.

[0009] Preferably, the bottom end of the upper connecting plate and the top end of the middle connecting plate are provided with an upper inclined surface that matches the upper arc-shaped structure of the middle plate and the two side plates, and the bottom end of the middle connecting plate and the top end of the lower connecting plate are provided with a lower inclined surface that matches the lower arc-shaped structure of the middle plate and the two side plates.

[0010] Preferably, the arc-shaped pressure strip matches the outer surface of the front connection structure formed by the upper connecting plate, upper front plate, middle connecting plate, lower front plate, and lower connecting plate.

[0011] Preferably, the side plate includes an upper side plate and a lower side plate, which are fixedly connected by a side plate connecting plate.

[0012] Preferably, the top of both the upper and lower side plates are provided with guide slopes.

[0013] Preferably, the discharge port of the dual-channel feeding chamber is provided with an anti-jump plate to prevent the material in the storage hopper on the circulation line from flying out to both sides. The anti-jump plate is inverted cone shape.

[0014] Preferably, the upper front panel and the lower front panel are transparent PC boards.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In this invention, the discharge bin is positioned at the corresponding position of the lower-level rotary paddle mechanism within the dual-channel feeding chamber. An upper-level rotary paddle mechanism is positioned above the lower-level rotary paddle mechanism. Specifically, when the photoelectric detection mechanism detects unqualified material, the material first falls to the upper-level paddle storage area. Only when the lower-level rotary paddle mechanism drives the paddle to rotate and connect with the discharge bin does the material fall from the upper paddle to the lower paddle and, guided by the lower paddle, is removed from the discharge bin. This effectively prevents material jamming and ensures the accuracy of the counting, sorting, and feeding process. The device is designed for stable operation. Furthermore, in the dual-channel feeding cavity, the front sides of the middle plate and both side plates are provided with arc-shaped structures that match the rotation path of the paddle at the corresponding positions of the upper and lower paddle rotating mechanisms. The arc-shaped pressure strips fix the malleable upper and lower front plates onto these arc-shaped structures, so that both the upper and lower front plates form arc-shaped plates. The arc-shaped plates are more matched with the rotation path of the paddle, which can prevent the paddle from rotating in the opposite direction when the feeding device is reset, thus avoiding material jamming and effectively preventing any impact on the stable operation of the feeding device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", 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 utility model 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 utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 8The present invention provides a novel counting, sorting and unloading device, including a photoelectric detection mechanism 2, a dual-channel unloading cavity 1, an upper-level paddle rotating mechanism 3 and a lower-level paddle rotating mechanism 4 located on both sides of the dual-channel unloading cavity 1. The photoelectric detection mechanism 2 is located at the inlet of the dual-channel unloading cavity 1. A cleaning chamber 5 connected to the upper-level paddle rotating mechanism 3 and a waste discharge chamber 6 connected to the lower-level paddle rotating mechanism 4 are provided at the rear of the dual-channel unloading cavity 1.

[0032] Specifically, the lower-level paddle rotation mechanism 4 is located below the upper-level paddle rotation mechanism 3. Both the upper-level paddle rotation mechanism 3 and the lower-level paddle rotation mechanism 4 include a driver and a paddle. The driver is located outside the dual-channel feeding cavity 1, and the paddle is located inside the dual-channel feeding cavity 1. The driver can drive the paddle to rotate inside the dual-channel feeding cavity 1. The upper-level paddle rotation mechanism 3 can drive the upper driver to rotate the upper paddle backward to connect with the cleaning bin 5, while the lower-level paddle rotation mechanism 4 can drive the lower driver to rotate the lower paddle backward to connect with the waste discharge bin 6.

[0033] In practical operation, the counting, sorting, and unloading device has two operating modes: a cleaning mode and a working mode. When the counting, sorting, and unloading device is in cleaning mode, the driver of the upper-level rotating mechanism 3 drives the upper rotating blade to rotate backward until it connects with the cleaning bin 5. Figure 4 As shown, the material from the feeding unit is cleared out of the unit along the upper deflector; when the counting, sorting, and unloading device is in working mode, the driver of the upper deflector rotation mechanism 3 drives the upper deflector to rotate forward to store material. The material falls onto the upper deflector through the inlet of the dual-channel unloading chamber 1. During this process, the photoelectric detection mechanism 2 detects the quantity and speed of the material. When it is determined that the material does not meet the set standard, the lower deflector rotation mechanism 4 causes the lower driver to drive the lower deflector to rotate backward until it connects with the waste discharge bin 6. Figure 5 As shown, the upper drive then drives the upper paddle to continue rotating forward, and defective materials fall from the upper paddle to the lower paddle and are removed along the discharge bin 6; when materials are determined to be qualified materials, the lower paddle rotates forward to a certain angle to store the material, and then the upper drive drives the upper paddle to continue rotating forward, and qualified materials fall from the upper paddle to the lower paddle, as shown. Figure 6 As shown, when the storage hopper of the circulation line reaches the discharge port of the counting and sorting feeding device, the lower paddle continues to rotate forward, and qualified materials fall into the storage hopper, completing the feeding process.

[0034] The discharge bin 6 is set at the corresponding position of the lower-level rotary mechanism 4. The material first falls onto the rotary mechanism 3 of the upper level and is stored there. When the photoelectric detection mechanism 2 detects that the material is unqualified, the driver of the lower-level rotary mechanism 4 drives the lower rotary mechanism to rotate until it is connected to the discharge bin 6. Only when it is in position will the material be lowered from the upper rotary mechanism to the lower rotary mechanism. This can prevent unqualified material from rotating backward with the rotary mechanism during discharge and getting stuck in the gap between the rotary mechanism and the front plate. This can ensure the stable operation of the counting, sorting and feeding device.

[0035] And, as Figures 3 to 8 As shown, the dual-channel feeding cavity 1 includes a middle plate 11, side plates 12 symmetrically distributed on both sides of the middle plate 11, and a front connecting structure 13 and a rear connecting plate 14 fixed to the front and rear of the middle plate 11 and the side plates 12. The front sides of the middle plate 11 and the two side plates 12 are respectively provided with arc-shaped structures matching the rotation path of the paddle at corresponding positions of the upper-level paddle rotation mechanism 3 and the lower-level paddle rotation mechanism 4. The front sides of the middle plate 11 and the two side plates 12 at the corresponding positions of the upper-level paddle rotation mechanism 3 have an upper arc-shaped structure, and the front sides of the middle plate 11 and the two side plates 12 at the corresponding positions of the lower-level paddle rotation mechanism 4 have a lower arc-shaped structure. The front connecting structure 13 includes a malleable... The upper front plate 15 and lower front plate 16 are provided with multiple arc-shaped pressure strips 7 on the outer side wall of the front connecting structure 13. The arc-shaped pressure strips 7 have an upper arc surface that matches the upper arc structure and a lower arc surface that matches the lower arc structure. The arc-shaped pressure strips 7 fix the upper front plate 15 and lower front plate 16 to the arc structure of the middle plate 11 and the two side plates 12. The upper and lower arc structures guide the upper front plate 15 and lower front plate 16, and the upper and lower arc surfaces of the arc-shaped pressure strips 7 press the upper front plate 15 and lower front plate 16, thereby bending the upper front plate 15 and lower front plate 16 into arc-shaped plates that match the rotation path of the upper-level paddle rotation mechanism 3 and the lower-level paddle rotation mechanism 4.

[0036] The arc-shaped plate is more compatible with the rotation path of the paddle, making the gap between the paddle and the arc-shaped plate formed by the upper front plate 15 and the lower front plate 16 smaller during the rotation of the paddle. Therefore, when the counting, sorting and feeding device stops working and the upper and lower paddles need to be rotated in the opposite direction to reset to the initial position, the material jamming on the paddle can be effectively avoided. Thus, the setting of the arc-shaped plate can effectively ensure the stable operation of the counting, sorting and feeding device.

[0037] In addition, the upper front panel 15 and the lower front panel 16 use transparent plastic sheets with malleability instead of aluminum sheets on the market, which greatly reduces the manufacturing cost.

[0038] Furthermore, such as Figures 3 to 8As shown, the front connecting structure 13 also includes an upper connecting plate 17 fixed above the upper front plate 15, a middle connecting plate 18 fixed between the upper front plate 15 and the lower front plate 16, and a lower connecting plate 19 fixed below the lower front plate 16. The bottom end of the upper connecting plate 17 and the top end of the middle connecting plate 18 press the upper and lower ends of the upper front plate 15 onto the upper arc-shaped structure of the middle plate 11 and the two side plates 12. The bottom end of the middle connecting plate 18 and the top end of the lower connecting plate 19 press the upper and lower ends of the lower front plate 16 onto the lower arc-shaped structure of the middle plate 11 and the two side plates 12. By pressing the ends of the upper front plate 15 and the lower front plate 16 with the upper connecting plate 17, the middle connecting plate 18 and the lower connecting plate 19, the upper front plate 15 and the lower front plate 16 can fit tightly into the upper arc-shaped structure and the lower arc-shaped structure of the middle plate 11 and the two side plates 12.

[0039] Furthermore, the curved pressure strip 7 matches the outer surface of the front connecting structure 13 formed by the upper connecting plate 17, the upper front plate 15, the middle connecting plate 18, the lower front plate 16, and the lower connecting plate 19. The upper, middle, and lower parts of the curved pressure strip 7 are fastened to the middle plate 11 and the two side plates 12 by fasteners. Therefore, in both the horizontal and vertical directions, it helps the upper front plate 15 and the lower front plate 16 to fit more tightly against the upper and lower curved structures of the middle plate 11 and the two side plates 12, so that the curved plates formed by the upper front plate 15 and the lower front plate 16 are more matched with the rotation path of the upper and lower levers, and the gap between the upper and lower levers and the upper and lower curved plates is minimized as much as possible, thereby effectively reducing the occurrence of material jamming.

[0040] Furthermore, such as Figure 7 As shown, the bottom end of the upper connecting plate 17 and the top end of the middle connecting plate 18 are both provided with upper inclined surfaces 171 that match the arc surfaces at the corresponding positions of the upper arc-shaped structures of the middle plate 11 and the two side plates 12, such as... Figure 8 As shown, the bottom end of the middle connecting plate 18 and the top end of the lower connecting plate 19 are provided with a lower inclined surface 191 that matches the arc surface of the lower arc structure of the middle plate 11 and the two side plates 12. By setting the matching upper inclined surface 171 and lower inclined surface 191, the end edges of the upper front plate 15 and the lower front plate 16 can be prevented from warping and affecting the final curved arc.

[0041] Furthermore, such as Figure 3 As shown, the side plate 12 includes an upper side plate 121 and a lower side plate 122. The upper side plate 121 and the lower side plate 122 are fixedly connected by a side plate connecting plate 8, dividing the side plate 12 into an upper side plate 121 and a lower side plate 122. They are detachably connected by the side plate connecting plate 8. Therefore, during maintenance, only one side of the upper side plate 121 or lower side plate 122 and other cooperating and connected parts need to be removed to replace a single lever. There is no need to disassemble the entire structure, which greatly reduces maintenance costs.

[0042] Furthermore, both the top of the upper plate 121 and the bottom plate 122 are provided with guide slopes 123. For the upper plate 121, the guide slopes 123 at the top can prevent materials from staying on the top table and affecting normal feeding. For the bottom plate 122, the guide slopes 123 can prevent materials from getting stuck in the gap between the upper plate 121 and the bottom plate 122 and affecting normal feeding. Therefore, the setting of guide slopes 123 can also ensure the stable operation of the counting, sorting and feeding device.

[0043] Furthermore, when the storage hopper of the circulation line reaches the discharge port of the counting and sorting feeding device, qualified materials will fall into the storage hopper as the lower deflector continues to rotate forward. Due to its resilience, the material in the storage hopper may bounce back and fly out of the hopper. Therefore, an anti-jump plate 9 is installed at the discharge port of the dual-channel feeding chamber 1. The anti-jump plate 9 is inverted conical in shape. The upper opening of the anti-jump plate 9 matches the discharge port of the dual-channel feeding chamber 1, and the lower opening of the anti-jump plate 9 matches the upper diameter of the storage hopper on the circulation line. In addition, a baffle is provided around the outside of the lower opening of the anti-jump plate 9. These designs can prevent the material in the storage hopper from flying out of the hopper, thereby avoiding affecting the material supply and ensuring the stable operation of the counting and sorting feeding device to a certain extent.

[0044] Furthermore, the upper front plate 15 and the lower front plate 16 are made of transparent PC sheets. Transparent PC sheets are highly malleable and wear-resistant, which can extend the service life of the feeding device. In addition, transparent PC sheets allow for easy observation of the rotation and usage of the paddle.

[0045] Furthermore, the upper connecting plate 17, the middle connecting plate 18, and the lower connecting plate 19 can be made of aluminum plates, or more preferably, transparent plastic plates, such as transparent PET plates and transparent PVC plates, to facilitate observation of the internal condition of the dual-channel feeding cavity 1 and reduce manufacturing costs.

[0046] In summary, in this invention, the discharge bin 6 is positioned at the corresponding position of the lower-level rotary paddle mechanism 4. Materials first fall onto the paddles of the upper-level rotary paddle mechanism 3 for storage. When the photoelectric detection mechanism 2 detects unqualified materials, the driver of the lower-level rotary paddle mechanism 4 drives the lower paddle to rotate until it connects with the discharge bin 6. Only when it reaches this position is the material lowered from the upper paddle to the lower paddle. This avoids unqualified materials from rotating backward with the paddle during discharge, preventing them from getting stuck in the gap between the paddle and the front plate, thus ensuring the stable operation of the counting, sorting, and feeding device. Furthermore, the dual-channel feeding chamber 1 has arc-shaped plates positioned at the corresponding positions of the upper-level rotary paddle mechanism 3 and the lower-level rotary paddle mechanism 4. The arc-shaped plates are more compatible with the paddle rotation path. Therefore, when the counting, sorting, and feeding device stops working and the upper and lower paddles need to be rotated in opposite directions to reset to their initial positions, material jamming on the paddles can be effectively avoided. Thus, the arc-shaped plates also effectively ensure the stable operation of the counting, sorting, and feeding device.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
