Description

Technical Field

[0001] This utility model belongs to the technical field of feeding mechanism, and in particular relates to a cam reciprocating two-station feeding mechanism. Background Technology

[0002] A material handling mechanism is a specialized piece of equipment in an automated system responsible for accurately transporting materials from storage devices (such as silos or trays) to subsequent processing, assembly, or testing stations. It can replace repetitive manual material handling operations, significantly improving production efficiency. Material handling mechanisms can be applied in various scenarios such as manufacturing, logistics warehousing, food, and medical industries.

[0003] A search revealed a single-station feeding machine with publication number CN220950119U published on the China Patent website. This feeding structure can achieve automated feeding, replacing tedious manual sorting, reducing operational errors, and improving safety. However, it has some defects and shortcomings that need to be improved: (1) Most existing feeding mechanisms are single-station designs. When feeding, the equipment needs to be stopped frequently. After the material handling operation is completed, the equipment is restarted to feed, resulting in a large amount of idle time in the entire feeding process, which reduces the overall work efficiency and equipment utilization rate; (2) When feeding, some existing feeding mechanisms generally place the material on a pallet and then lift the pallet along with the material through a lifting structure to complete the feeding. During this process, the material is prone to slipping and displacement and falling off the pallet, which can not only cause material damage but also pose a safety hazard. Therefore, in view of the above problems, the cam reciprocating two-station feeding mechanism provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides a cam-type reciprocating two-station feeding mechanism. Through the reciprocating rotation of the first and second cams, continuous feeding is achieved between two feeding stations using the cooperation of two pallets, eliminating the need for frequent machine stops for material handling. Compared to existing feeding mechanisms, this significantly reduces idle time and effectively improves overall work efficiency and equipment utilization. When the two pallets are reciprocally lifted or lowered by the reciprocating feeding assembly, the first and second lifting blocks can move up and down along the inner wall of the sleeve. The sleeve acts as a guide and limiter, ensuring the pallets are always lifted or lowered vertically. This effectively prevents the pallets from swaying or tilting during lifting, thus maintaining the stability of the material inside. When material is placed in the pallet, the side guards prevent displacement and falling off the pallet during lifting. Simultaneously, the anti-slip texture on the anti-slip pad increases friction between the material and the pallet, preventing slippage and displacement. In summary, this solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a cam-type reciprocating two-station feeding mechanism, including a base, a frame fixedly connected to the top of the base, feeding ports on both sides of the frame, a partition fixedly connected to the inner wall of the frame, a through hole on the partition, and feeding stations on both sides of the partition. A reciprocating feeding assembly is installed inside the feeding station. A bracket is fixedly connected to the top of the partition, a fixing plate is fixedly connected to the top of the bracket, and electric telescopic rods are installed at the bottom of both ends of the fixing plate. A mounting base is fixedly connected to the bottom of the output shaft of the electric telescopic rod, and a gripper is installed at the bottom of the mounting base. The two grippers are respectively located directly above the two feeding stations.

[0007] The reciprocating feeding assembly includes a motor and a pair of trays. The motor is mounted on one side of the frame, and its output shaft is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through a through hole in the partition, and its end is rotatably connected to the other side of the frame via a bearing. The shaft body of the rotating shaft is fixedly connected to a first cam and a second cam, which are located inside two feeding stations respectively. The two trays are located inside two feeding stations respectively, and the bottom of the two trays is fixedly connected to a first top block and a second top block, which are both inverted T-shaped with equal length and width. The bottom surfaces of the first top block and the second top block are respectively attached to the top surfaces of the first cam and the second cam.

[0008] Furthermore, both the first cam and the second cam are disc-shaped cam structures with the same shape, and the first cam and the second cam are centrally symmetrically distributed with the partition plate as the center.

[0009] Furthermore, both the pallet and the loading station are rectangular, and the length and width of the pallet are equal to the length and width of the loading station, respectively. The discharge port is rectangular, and its length is equal to the length of the pallet. The distance between the discharge port and the top surface of the loading station is equal to the distance between the top and bottom surfaces of the first cam and the second cam.

[0010] Furthermore, connecting blocks are fixedly connected to both sides of the partition, and sleeves are fixedly connected to the ends of the connecting blocks. The sleeves are square-shaped and are respectively fitted onto the first top block and the second top block. The cross-sections of the first top block and the second top block are both rectangular, and their length and width are equal to the length and width of the inner wall of the sleeve, respectively.

[0011] Furthermore, the top edge of the tray is provided with an upwardly protruding guard, and the top surface of the tray is provided with a number of slots. The slots are rectangular and are distributed linearly at equal intervals along the length of the tray. Each slot is provided with an anti-slip pad. The anti-slip pad is rectangular and has a herringbone anti-slip texture on its surface. The length and width of the anti-slip pad are equal to the length and width of the slot, respectively.

[0012] Furthermore, each of the card slots has a take-out groove on its top surface. The take-out groove is semi-circular, symmetrically distributed at both ends of the card slot and connected to the card slot. The depth of the take-out groove is less than the depth of the card slot.

[0013] Furthermore, a buffer ring is provided on the inner side of the top edge of the tray, and the buffer ring is rectangular.

[0014] The present invention has the following advantages over the prior art:

[0015] (1) The two-station design can realize continuous feeding without frequent machine stop: Through the reciprocating feeding component, the reciprocating rotation of the first cam and the second cam can realize continuous feeding in the two feeding stations through the cooperation of the two trays, without frequent machine stop for picking and unloading operations. Compared with the existing feeding mechanism, it not only greatly shortens the idle time, but also effectively improves the overall work efficiency and equipment utilization.

[0016] (2) The material can remain stable during the lifting process and is not easy to fall: When the two pallets are lifted or lowered by the reciprocating feeding component, the first and second top blocks can move up and down along the inner wall of the sleeve. At this time, the sleeve can play a guiding and limiting role to ensure that the pallet is always lifted or lowered in the vertical direction, thereby effectively preventing the pallet from shaking and tilting during the lifting process and affecting the stability of the material in the pallet. When the material is placed in the pallet, the edge can be used to block the material to prevent the material from shifting and falling off the pallet during the lifting process. At the same time, the anti-slip texture on the surface of the anti-slip pad can increase the friction between the material and the pallet to play an anti-slip role, thereby effectively preventing the material from slipping and shifting during the lifting process.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5 As shown, the present invention discloses a cam reciprocating two-station feeding mechanism, including a base 1, a frame 2 fixedly connected to the top of the base 1, feeding ports 3 on both sides of the frame 2, a partition 4 fixedly connected to the inner wall of the frame 2, a through hole 5 on the partition 4, and feeding stations 6 on both sides of the partition 4. A reciprocating feeding assembly is installed inside the feeding station 6. A bracket 7 is fixedly connected to the top of the partition 4, a fixing plate 8 is fixedly connected to the top of the bracket 7, and electric telescopic rods 9 are installed at the bottom of both ends of the fixing plate 8. A mounting base 10 is fixedly connected to the bottom of the output shaft of the electric telescopic rod 9, and a gripper 11 is installed at the bottom of the mounting base 10. The two grippers 11 are located directly above the two feeding stations 6 respectively.

[0029] The reciprocating feeding assembly includes a motor 12 and a pair of trays 13. The motor 12 is mounted on one side of the frame 2, and its output shaft is fixedly connected to a rotating shaft 14 via a coupling. The rotating shaft 14 passes through a through hole 5 on a partition 4, and its end is rotatably connected to the other side of the frame 2 via a bearing. The shaft body of the rotating shaft 14 is fixedly connected to a first cam 15 and a second cam 16, respectively. The first cam 15 and the second cam 16 are located inside two feeding stations 6, respectively. The two trays 13 are located inside two feeding stations 6, and the bottom part of the two trays 13... A first top block 17 and a second top block 18 are fixedly connected. Both the first top block 17 and the second top block 18 are inverted T-shaped, with equal length and width. The bottom surfaces of the first top block 17 and the second top block 18 are respectively attached to the top surfaces of the first cam 15 and the second cam 16. The drive motor 12 can drive the rotating shaft 14 to reciprocate together with the first cam 15 and the second cam 16. When the first cam 15 and the second cam 16 reciprocate, the first top block 17 and the second top block 18, together with the corresponding tray 13, can be reciprocated to lift or lower.

[0030] Both the first cam 15 and the second cam 16 are disc-shaped cams with identical shapes. They are centrally symmetrically distributed around the partition 4. When the protruding end of either the first cam 15 or the second cam 16 rotates to a vertically upward position, it can lift the corresponding tray 13 to its highest point. Conversely, when the protruding end of either the first cam 15 or the second cam 16 rotates to a vertically downward position, it can lower the corresponding tray 13 to its lowest point. When the tray 13 is lifted to its highest point, its top surface is level with the top surface of the loading station 6. At this point, the electric telescopic rod 9 can be driven to move the mounting base 10 along with the gripper 11. Together they move downwards until the gripper 11 moves into the corresponding tray 13. The gripper 11 can grab the material in the tray 13 and transfer it to the subsequent processing, assembly or inspection station to complete the loading work. The electric telescopic rod 9 is equipped with a position sensor, which is electrically connected to the controller on the electric telescopic rod 9. When the position sensor detects that the tray 13 has moved to the top surface of the loading station 6, the controller can trigger the electric telescopic rod 9 to drive the gripper 11 to perform the grabbing and releasing operation. The gripper 11 is a publicly available technology and can be purchased directly from the market. Its specific component connection and working principle will not be described here.

[0031] Both the pallet 13 and the loading station 6 are rectangular, with the length and width of the pallet 13 corresponding to the length and width of the loading station 6, respectively. The discharge port 3 is rectangular, with its length corresponding to the length of the pallet 13. The distance between the discharge port 3 and the top surface of the loading station 6 corresponds to the distance between the top and bottom surfaces of the first cam 15 and the second cam 16. The pallet 13 can be repeatedly lifted or lowered along the inner wall of the loading station 6. When one pallet 13 is lifted to its highest point and is level with the top surface of one of the loading stations 6, the other pallet 13... The material is lowered to its lowest position and level with the height of one of the discharge ports 3. At this time, while feeding material onto one of the pallets 13, material can be picked up and put on the other pallet 13 through the discharge port 3. The reciprocating rotation of the first cam 15 and the second cam 16 can be used to achieve continuous feeding in the two feeding stations 6 through the cooperation of the two pallets 13, without the need for frequent machine stops for picking up and putting on materials. Compared with the existing feeding mechanism, this not only greatly shortens the idle time, but also effectively improves the overall work efficiency and equipment utilization rate.

[0032] The partition 4 is fixedly connected to both sides of the connecting block 19, and the end of the connecting block 19 is fixedly connected to the sleeve 20. The sleeve 20 is a square tube and is respectively fitted onto the first top block 17 and the second top block 18. The cross-section of the first top block 17 and the second top block 18 is rectangular, and their length and width are equal to the length and width of the inner wall of the sleeve 20. When the two pallets 13 are reciprocally lifted or lowered by the reciprocating feeding assembly, the first top block 17 and the second top block 18 can move up and down along the inner wall of the sleeve 20. At this time, the sleeve 20 can play a guiding and limiting role to ensure that the pallets 13 are always lifted or lowered in the vertical direction, thereby effectively preventing the pallets 13 from shaking and tilting during the lifting process, which would affect the stability of the material in the pallets 13.

[0033] The pallet 13 has an upwardly protruding edge at its top edge, and several rectangular slots 21 are provided on the top surface of the pallet 13. These slots are equidistantly distributed along the length of the pallet 13, and each slot 21 contains an anti-slip pad 22. The anti-slip pad 22 is rectangular with herringbone anti-slip texture on its surface, and its length and width correspond to the length and width of the slot 21, respectively. The anti-slip pad 22 can be inserted into and adhered to the inner wall of the slot 21 for fixation. The anti-slip pad 22 is made of nitrile rubber or silicone. When materials are placed in the pallet 13, the edge can block the materials to prevent them from shifting and falling off the pallet 13 during lifting and lowering. At the same time, the anti-slip texture on the surface of the anti-slip pad 22 can increase the friction between the materials and the pallet 13, thus preventing slippage and displacement of materials during lifting and lowering of the pallet 13.

[0034] Each slot 21 has a take-out groove 23 on its top surface. The take-out groove 23 is semi-circular, symmetrically distributed at both ends of the slot 21 and connected to the slot 21. The depth of the take-out groove 23 is less than the depth of the slot 21. When the anti-slip texture on the surface of the anti-slip pad 22 is worn flat, two fingers can be inserted into the two take-out grooves 23 respectively and the two ends of the anti-slip pad 22 can be pinched at the same time to quickly remove the anti-slip pad 22 from the slot 21 and replace it.

[0035] The pallet 13 has a buffer ring 24 on the inner side of the top edge. The buffer ring 24 is rectangular and made of flexible materials such as sponge. It is fixed by adhesives and other means. The buffer ring 24 can buffer and absorb energy to prevent materials from directly contacting the inner side of the pallet 13 and causing collisions and wear.

[0036] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0037] The working principle of this utility model is as follows:

[0038] In use, materials can be placed on one of the trays 13 through the discharge port 3. Then, the drive motor 12 drives the rotating shaft 14, along with the first cam 15 and the second cam 16, to rotate reciprocally. When the first cam 15 and the second cam 16 rotate reciprocally, the first top block 17 and the second top block 18, along with the corresponding tray 13, can be lifted or lowered respectively. When the tray 13 containing materials is lifted to its highest point, its top surface is level with the top surface of the loading station 6. At this time, the gripper 11 can be used to grab the materials in the tray 13. The material is picked up and transferred to subsequent processing, assembly, or inspection stations to complete the loading work. Simultaneously, another tray 13 is lowered to its lowest position, level with one of the discharge ports 3. At this point, while loading material onto the tray 13, material can be picked up and placed onto the other tray 13 through the discharge port 3. This allows for continuous loading within the two loading stations 6 through the cooperation of the two trays 13, utilizing the reciprocating rotation of the first cam 15 and the second cam 16, without frequent machine stops for picking up and placing materials. Compared to the current... Some feeding mechanisms not only significantly reduce idle time but also effectively improve overall work efficiency and equipment utilization. When the two pallets 13 are reciprocally lifted or lowered by the reciprocating feeding assembly, the first top block 17 and the second top block 18 can move up and down along the inner wall of the sleeve 20. At this time, the sleeve 20 can play a guiding and limiting role to ensure that the pallets 13 are always lifted or lowered in a vertical direction, thereby effectively preventing the pallets 13 from shaking or tilting during the lifting process and affecting the stability of the materials inside the pallets 13. When the material is placed on the pallet 1... When the pallet is raised or lowered, the guard edge can be used to block the material to prevent it from shifting and falling off the pallet 13 during the lifting and lowering process. At the same time, the anti-slip texture on the surface of the anti-slip mat 22 can increase the friction between the material and the pallet 13 to play an anti-slip role, thereby effectively preventing the material from slipping and shifting during the lifting and lowering process of the pallet 13. A buffer ring 24 is provided on the inner side of the top guard edge of the pallet 13. The buffer ring 24 can play a buffering and energy absorption role to prevent the material from directly contacting the inner side of the guard edge of the pallet 13 and causing collision and wear.
