[0033] It is to be understood that the figures are merely schematic and that actual implementations can differ from the presented embodiments, for example in terms of shape, size and relative arrangement of parts. The present application seeks to obviate or at least mitigate the above mentioned disadvantages.

[0034] The present embodiment proposes a rod-shaped material loading device, as shown in the figure, which is composed of a conical hopper 1, a primary material distributing device 2, a transition inclined surface 3, a material taking table 4, a secondary material distributing device 5 and a control cabinet 6. Figure 1 The conical hopper 1 is installed at the position of the feeding port, which is used to guide the rod-shaped material 7 into the feeding port.

[0035] The primary material distributing device 2 is installed at the position of the feeding port, which is used to distribute the rod-shaped material 7 into the feeding port.

[0036] The transition inclined surface 3 is installed at the position of the feeding port, which is used to guide the rod-shaped material 7 into the feeding port. Figure 2As shown, the primary material distributing device 2 comprises an upper cover plate 202, flange bearings 201, a rotating shaft 204, a rotating disc 205 and a gear 206, two flange bearings 201 are respectively connected and fixed on the two inner sides of the end face cover plate 203 through screws, the two ends of the rotating shaft 204 are respectively connected with the two flange bearings 201, so that the rotating shaft 204 can rotate. The rotating disc 205 is fixed on the rotating shaft 204 and can rotate with the rotating shaft 204, the number of the rotating disc 205 in the embodiment is 5, which are arranged at intervals along the axial direction of the rotating shaft 204, the circumferential surface of the rotating disc 205 is provided with a notch 207, the notches 207 of all the rotating discs 205 are in the same direction, all the notches 207 are used for carrying the same rod-shaped material 7, and the interval of the notch 207 is related to the length of the rod-shaped material 7 to be distributed. In the embodiment, the number of rod-shaped materials 7 to be distributed at the same time can be selected according to the diameter of the rod-shaped material 7, and then the tapered material bin 1 is put into the notch 207 at the same time.

[0037] The first propulsion mechanism 507 and the first actuator 501 are fixedly installed on the base chassis 503, and the first actuator 501 provided with the rack 502 is driven to move along the first inclined surface 503 by the first propulsion mechanism 507 through the cylinder connecting plate 505.

[0038] As shown in Figure 3 , the second propulsion mechanism 403 and the third propulsion mechanism 405 of the material taking table 4 are respectively installed on the two sides of the V-shaped groove 404, the second propulsion mechanism 403 is provided with the second actuator 401, and the third propulsion mechanism 405 is provided with the third actuator 402.

[0039] As shown in Figure 4 and 5 , the first inclined surface 507 is arranged below the feeding port, the first inclined surface 507 and the second inclined surface 407 are connected in series, and the first inclined surface 507 and the second inclined surface 407 are both gradually inclined upward along the direction of approaching each other, that is, the position connected between the first inclined surface 507 and the second inclined surface 407 forms an acute angle.

[0040] The first propulsion mechanism 507 in the embodiment is a diagonal cylinder, the output end of the first propulsion mechanism 507 is connected with the first actuator 501, and the first propulsion mechanism can drive the rod-shaped material 7 on the first inclined surface 507 to roll in the direction gradually approaching the second inclined surface 407 by extending the first actuator.

[0041] The output end of the second pushing mechanism 403 is connected with a second execution member 401, and the second execution member 401 is provided with a third inclined surface 406 located at the side of the first inclined surface 507, and the inclination direction of the third inclined surface 406 is the same as that of the second inclined surface 407. When the rod-shaped material 7 moves to the first preset position, the second pushing mechanism 403 drives the second execution member 401 to extend and drive the rod-shaped material 7 to move, so that the third inclined surface 406 and the second inclined surface 407 are continuous, and the rod-shaped material 7 can roll from the third inclined surface 406 to the second inclined surface 407.

[0042] In the embodiment, when the rod-shaped material 7 passes through the feeding opening and enters the first inclined surface 507, the first inclined surface 507 and the second inclined surface 407 are connected in series, and the first inclined surface 507 and the second inclined surface 407 are both gradually inclined upward along the direction close to each other, so that the rod-shaped material 7 cannot flow to the second inclined surface 407 under the action of gravity. At this time, the first execution member 501 is extended by the first pushing mechanism 506 to push the rod-shaped material 7 to roll on the first inclined surface 507, as shown in Figure 7 and 8 When rolling to the first preset position, the first preset position in the embodiment is located at the top end of the third inclined surface 406, and the inclination direction of the third inclined surface 406 is the same as that of the second inclined surface 407. At this time, the second execution member 401 is gradually extended by the second pushing mechanism 403, and drives the rod-shaped material 7 to rise until the third inclined surface 406 and the second inclined surface 407 are continuous. At this time, the relative position of the two is as shown in Figure 8 Under the action of gravity, the rod-shaped material 7 rolls on the second inclined surface 407. In the embodiment, by setting the size of the first preset position and the third inclined surface 406, the feeding of a single or a small number of rod-shaped materials 7 can be realized.

[0043] In the embodiment, the side of the first execution member 501 is provided with a rack 502, the rack 502 is engaged with a gear 206, and the rack 502, the gear 206 and a rotating shaft 204 constitute a transmission mechanism for driving the rotating disc 205 to rotate. When the first execution member 501 moves towards the second inclined surface 407, that is, the first pushing mechanism 506 is extended, the rotating disc 205 is driven to rotate counterclockwise, so that the slot 207 moves downward. Conversely, when the first pushing mechanism 506 is retracted, the rotating disc 205 rotates clockwise, and the slot 207 rotates upward.

[0044] As shown in Figure 5 and 6 The rod-shaped material feeding device further comprises a transition inclined surface 3. When the rotating disc 205 rotates downward, the slot 207 passes through the transition inclined surface 3, and the first inclined surface 507 is located below the transition inclined surface 3, so that the rod-shaped material 7 can roll on the first inclined surface 507 in sequence through the transition inclined surface 3. Figure 5 and 6The process of rolling the rod material 7 in the slot 207 to the transition slope 3 is shown. In this embodiment, during the rotation of the rotating disc 205, part of the rod material 7 is rolled from the slot 207 to the transition slope 3, and then rolled from the transition slope 3 to the first slope 507, avoiding excessive rod material 7 from directly accumulating on the first slope 507.

[0045] In order to further avoid excessive rod material 7 on the first slope 507, thereby causing the accumulation of rod material 7, in this embodiment, the minimum distance between the circumferential surface of the rotating disc 205 and the transition slope 3 is less than or equal to the diameter of the rod material 7. When the first advancing mechanism 506 is retracted to drive the rotating disc 205 to rotate counterclockwise, the part of the rod material 7 that has not been rolled onto the first slope 507 is dragged by the rotating disc 205 towards the direction away from the first slope of the transition slope 3. Or make part of the rod material 7 enter the slot 207.

[0046] In order to further avoid the accumulation of rod material 7 on the first slope, in this embodiment, the first slope 507 has a second preset position. When the front end of the first actuator 501 slides between the first preset position and the second preset position, the first actuator 501 separates the end of the transition slope 3 from the first slope 507, so that the transition slope 3 is discontinuous with the first slope 507, allowing part of the rod material 7 on the transition slope 3 to roll to the top of the first actuator 501, thereby reducing the number of rod materials 7 rolling onto the first slope 507.

[0047] The first preset position in this embodiment is located at the end of the first slope 507, and the second preset position is related to the length of the first actuator 501 and the relative position of the transition slope 3 and the first slope 507. In this embodiment, the first preset position is provided with a pair of infrared sensors 504 on the side.

[0048] This embodiment also includes a control cabinet 6, and a controller in the control cabinet 6 executes the control logic of the feeding. Specifically:

[0049] S1: The worker puts the rod material 7 to be sent into the slot 207 through the conical hopper 1;

[0050] S2: Drive the rotating disc 205 to rotate counterclockwise. The worker can control the first advancing mechanism 506 to extend through the control cabinet 6, or a weight sensor can be arranged inside the slot 207. When the weight sensor receives a weight signal, the controller controls the first advancing mechanism 506 to extend, thereby pushing the rod material 7 on the first slope 507 to move towards the second slope 407;

[0051] S3: When the pair of sensors 504 is blocked, the controller controls the first pushing mechanism 506 to stop, and then controls the second pushing mechanism 405 to extend, thereby lifting the rod-shaped material 7, when the stroke of the second actuator reaches the second preset stroke, i.e. the third slope and the second slope are continuous, the rod-shaped material 7 rolls onto the second slope, at this time the controller controls the second pushing mechanism to retract;

[0052] S4: The first pushing mechanism continues to push until the stroke of the first actuator reaches the first preset stroke, then the controller controls the first pushing mechanism to retract, the end position of the first preset stroke in the embodiment is in front of the pair of sensors 504, i.e. the position just not blocking the pair of sensors, which can ensure that all the rod-shaped materials 7 on the first slope 507 are transferred to the second slope;

[0053] S5: When the single rod-shaped material 7 reaches the V-shaped groove 404 (this step can also be realized by monitoring through the weight sensor arranged at the bottom of the V-shaped groove), the controller controls the third pushing mechanism 405 to drive the third actuator 402 to extend, thereby pushing the rod-shaped material 7 to move;

[0054] S6: When the rod-shaped material 7 moves to the feeding position (in the embodiment, a proximity sensor is arranged at the feeding position), the proximity sensor can sense the rod-shaped material 7, at this time the controller controls the third pushing mechanism 405 to retract the third actuator 402.

[0055] The above embodiment is only a preferred embodiment for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent replacement or transformation of the present application based on the present application is within the protection scope of the present application.
