For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] The utility model provides a round product unloading mechanism, comprising a lifting and transferring structure 1 and a flipping and conveying mechanism 2, the lifting and transferring mechanism 1 comprising a supporting part 11 and a vertical guiding assembly 12, the vertical guiding assembly 12 being arranged on one of the side plates of the equipment 5, the supporting part 11 being fixed to an actuator of the vertical guiding assembly 12, the flipping and conveying mechanism 2 being arranged between the equipment 5 and the vertical guiding assembly 12, and close to the bottom of the equipment 5, the actuator of the vertical guiding assembly 12 being lifted and lowered causes the supporting part 11 to be lifted and lowered, thereby causing the supporting part 11 to be able to reciprocate up and down, when the supporting part 11 is lifted to a high position, it can receive the round product 6 that falls from the tooling; when the supporting part 11 is lowered to the lowest position, the round product 6 is transferred to the flipping and conveying mechanism 2, the flipping and conveying mechanism 2 is flipped toward the direction of the equipment 5, the round product 6 whose axial direction is in a horizontal state is flipped to a state whose axial direction is in a vertical state, and the round product 6 is flipped on a conveyor on an overhead layer at the bottom of the equipment 5.

[0029] Since the lifting mechanism of the utility model is vertically lifted, it is basically attached to the device 5 and does not exceed the device 5 by much space. In addition, the device 5 is mounted on a shelf so that the bottom of the device 5 is suspended and the conveyor can be placed under the device 5. In the initial state, the actuator of the vertical guide assembly 12 is at the top, so that the supporting part 11 is also at the top. At this time, the supporting part 11 can just catch the circular product 6 loosened from the clamp. The supporting part 11 descends along the actuator and transfers the circular product 6 to the flipping and conveying mechanism 2. The flipping and conveying mechanism 2 flips toward the device 5, so that the axially horizontal circular product 6 can be flipped onto the conveyor. In summary, by setting the conveyor below the device 5 and combining the structure of the utility model, the utility model does not exceed the range of the device 5 by too much, and reduces the total space occupied by the device 5.

[0030] Specifically, the vertical guide assembly 12 is composed of two guide rail slider pairs, which are fixed at intervals on one of the side panels of the device 5. Each guide rail slider pair includes a vertical guide rail 121 and a slider 122 that slides on the guide rail 121. The supporting part 11 is fixed on the two sliders 122 and slides on the guide rail 121 to provide guidance for the lifting and lowering of the supporting part 11.

[0031] Specifically, the supporting part 11 includes a slider connecting plate 111 and two horizontal supporting rods 112. The two sides of the slider connecting plate 111 are respectively fixed to two sliders 122. The supporting rods 112 are fixed at intervals on the side of the slider connecting plate 111 facing the device 5, and the round product 6 can fall on the two supporting rods 112. The main function of the slider connecting plate 111 is to connect the supporting rods 112 and the slider 122. The supporting rods 112 rise and fall with the slider 122, and the main function of the supporting rods 112 is to support the circumferential surface of the round product 6.

[0032] The flip mechanism includes a material receiving portion 21 that can be flipped and rotated 90°. The material receiving portion 21 includes a first panel 211 and a second panel 212 that are perpendicular to each other. The second panel 212 is fixed to one end of the first panel 211 close to the device 5. In the initial state, the first panel 211 is in a horizontal state and the second panel 212 is in a vertical state. The first panel 211 is located between the two support rods 112, so that when the two support rods 112 are lifted, the first panel 211 can pass between the two support rods 112. When the lifting and transfer mechanism 1 transfers the circular product 6, after the two support rods 112 are lowered below the first panel 211, the circular product 6 is trapped on the first panel 211 and is transferred to the flip mechanism. When the flip mechanism receives the circular product 6, the flip mechanism first flips 90° in the direction of the device 5 (that is, the conveyor 4 direction), so that the second panel 212 becomes horizontal, the first panel 211 becomes vertical, and the second panel 212 is just attached to the conveyor 4, so that the circular product 6 is transferred to the conveyor 4 again.

[0033] In addition, when the supporting portion 11 is receiving and delivering the circular product 6, the second panel 212 is still in a vertical state, which can provide support for one of the end faces of the circular product 6, thereby reinforcing the support for the circular product 6 and preventing the circular product 6 from tipping toward the device 5.

[0034] The flip mechanism also includes a transmission mechanism 22 and a driving mechanism I23, the transmission mechanism 22I includes a rotating shaft 221, a first connecting rod 222 and a second connecting rod 223, the driving mechanism I23 is a cylinder I, the rotating shaft 221 is horizontally rotatably connected to the bottom of the frame, the first panel 211 is fixed on the rotating shaft 221, the cylinder I is inverted and fixed on the frame, one end of the first connecting rod 222 is fixed on the rotating shaft 221, one end of the second connecting rod 223 is fixed to the free end of the telescopic rod of the cylinder I, and the other end of the second connecting rod 223 is hinged to the other end of the first connecting rod 222. In the initial state, the telescopic rod of the cylinder I is relatively long, and the first panel 211 of the material receiving part 21 remains in a horizontal state. When the round product 6 is transferred to the conveyor 4, the telescopic rod of the cylinder I is shortened, and the first connecting rod 222 rotates toward the device 5 with its end fixed to the rotating shaft 221 as the rotation center, thereby driving the rotating shaft 221 to rotate toward the device 5, and finally causing the material receiving part 21 to rotate 90° toward the device 5 (the first panel 211 becomes a vertical state, and the second panel 212 becomes a horizontal state). When the material receiving part 21 needs to be restored, it is only necessary to extend the telescopic rod of the cylinder I to the original length.

[0035] There are two drive mechanisms Ⅰ23 (cylinder Ⅰ), which are respectively arranged at both ends of the rotating shaft 221 and act on the rotating shaft 221 together. A single drive mechanism Ⅰ23 (cylinder Ⅰ) causes the entire device to tilt toward one side, causing the slider 122 on that side to wear faster. The utility model is provided with double cylinders to ensure the balance of the device, so that the slider 122 is evenly stressed and its life is extended.

[0036] Setting the drive mechanism I23 as a cylinder can enable the material receiving part 21 to accurately control the rotation angle when rotating and swiveling to better meet the angle required. Because the cylinder can be made with a fixed stroke, there will be no problem of exceeding the predetermined stroke during operation, while the motor relies on the sensor to limit the stroke. If the sensor is damaged, the actual stroke of the motor is likely to exceed the preset stroke, causing a safety accident. In the utility model, if a motor is used as the drive mechanism of the flipping and conveying mechanism, the entire equipment assembly is likely to overturn when the motor exceeds the predetermined stroke. In addition, the cylinder is easier to maintain than the motor and has a lower cost.

[0037] The receiving portion 21 further includes a front baffle 213, one end of which is fixed to the other end of the first panel 211 away from the device 5, and the front baffle 213 is parallel to the second panel 212. The arrangement of the front baffle 213 makes the receiving portion 21 a U-shape, and when the supporting portion 11 transfers the round product 6 to the receiving portion 21, the arrangement of the front baffle 213 can prevent the round product 6 from tipping toward the lifting and transferring mechanism 1 when the axial direction is in a horizontal state.

[0038] The utility model also includes a push centering mechanism 3, which includes a cylinder II 31 and a push plate 32. The cylinder II 31 is fixed on the outer side of the first panel 211, and the axial direction of the cylinder is perpendicular to the length direction of the first panel 211. The telescopic rod of the cylinder II 31 passes through the first panel 211, and the push plate 32 is located on the inner side of the first panel 211. The push plate 32 is parallel to the first panel 211, and the push plate 32 is fixed to the free end of the telescopic rod of the cylinder II 31. The purpose of the push centering device is to ensure that the flip conveying mechanism 2 can keep the circular product 6 centered on the conveyor after transferring it to the conveying mechanism. When the receiving part 21 is flipped (that is, the first panel 211 becomes vertical), the push centering mechanism 3 starts to start, and the telescopic rod of the cylinder II 31 is extended, so that the push plate 32 moves toward the device 5, just pushing the circular product 6 toward the device 5 away from the flip conveying mechanism 2.

[0039] The lifting and transporting mechanism 1 also includes the driving mechanism II13, the driving mechanism II13 includes a chain 139, a sprocket I131, a sprocket II132, a sprocket III133, a sprocket IV134, a sprocket V135, a sprocket VI136 and a connecting frame 137, one end of the chain 139 is fixed to the supporting portion 11 (specifically, to the slider connecting plate 111), and the other end is fixed to the equipment, the cylinder III138 is transversely fixed to the equipment, and the cylinder III138 is provided The telescopic rod faces the front side of the equipment, the telescopic rod of the cylinder III 138 is fixed to the connecting frame 137, the sprocket I 131, the sprocket II 132, the sprocket III 133, and the sprocket IV 134 are rotatably connected to the equipment, the sprocket V 135 and the sprocket VI 136 are rotatably connected to the connecting frame 137, and the chain 139 is S-shapedly meshed with the sprocket I 131, the sprocket II 132, the sprocket V 135, the sprocket III 133, the sprocket VI 136, and the sprocket IV 134 in sequence. The main function of the driving mechanism II 13 is to provide power for the lifting and lowering of the supporting part 11. The above structural design adopts a sprocket chain stroke amplification mechanism to improve the transmission efficiency of the chain 139, so that the lifting stroke of the supporting part 11 is 4 times the stroke of the cylinder III 138. Moreover, this type of structure can amplify the stroke of the cylinder III 138 without occupying a large space, making the support part 11 more efficient in picking up and delivering.

[0040] The spacing between the two support rods 112 can be adjusted toward each other or in opposite directions. This structural design has two functions: first, it can be used for round products 6 of different diameters: when the spacing between the two support rods 112 is increased, a larger round product 6 can be transported, and when the spacing between the two support rods 112 is decreased, a smaller round product 6 can be transported; second, the spacing between the two support rods 112 is adjusted to the optimal state, so that the round product 6 is more stable when being transported and is not easy to fall.

[0041] Two spaced, horizontally arranged elongated holes 1a are provided on the slider connecting plate 111, and two support rods 112 are respectively fixed to the two elongated holes 1a by fasteners. When adjusting the spacing, just loosen the fasteners and move the support rods 112 along the length direction of the elongated holes 1a.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
