Description

Technical Field

[0001] The utility model relates to the technical field of material commutation equipment, in particular to a conical material conveying and commutation device. Background Art

[0002] In the field of automatic industry, conical materials (such as metal parts, container plugs, biological gun heads, biological test tubes, etc.) are usually sorted, conveyed, and direction-identified by using conventional vibrating bowls or devices combining vibrating bowls with robotic arms.

[0003] The conventional vibrating bowl uses the exciting force generated by the cooperation of pulse electromagnets and springs to sort the materials in the tray and convey them spirally upward to the material direction screening device. Among them, the materials that conform to the set direction will directly pass through the screening area and be conveyed to the discharge port, while the materials that do not conform to the set direction will leak back into the chute for multiple cycle screening until they meet the set requirements and then be conveyed to the discharge port.

[0004] The device combining a vibrating bowl with a robotic arm first arranges the materials regularly through the vibrating bowl. The robotic arm takes them one by one by setting corresponding coordinates through a computer or directly judges and takes the materials through image recognition, and then transfers the materials to a specified area.

[0005] As can be seen from the above, due to structural reasons, the conventional vibrating bowl is not easy to be miniaturized, and the device combining a vibrating bowl with a robotic arm is not only not easy to be miniaturized, but also has a high cost due to its complex components. Content of the Utility Model

[0006] The purpose of the utility model is to provide a conical material conveying and commutation device to solve the problem that the existing vibrating bowl for conical material sorting and direction identification is not easy to be miniaturized.

The depths of the two arc-shaped grooves gradually decrease along the rotation direction of the turning barrel and finally connect to the end face of the baffle state disk. The positions of the deepest parts of the two arc-shaped grooves are respectively facing the temporary storage bracket and vertically downward;

[0008] When the turning barrel is in the initial position: The inlets of the small-end material holes correspond to the grooves on the temporary storage bracket one by one. The material blocking piece at the inlet of the small-end material hole blocks part of the small-end material holes. The end of the transmission column at the inlet of the small-end material hole is located in the deepest part of one of the arc-shaped grooves. The ends of the transmission columns at the inlets of the large-end material holes and the outlets of the small-end material holes are both in contact with the end face of the baffle state disk. The material blocking piece at the inlet of the large-end material hole blocks part of the large-end material holes. The material blocking piece at the outlet of the small-end material hole blocks part of the small-end material holes;

[0009] When the end parts of the transmission columns at the large-head material hole inlet and the small-head material outlet respectively rotate to the deepest part of the arc-shaped grooves, the material baffle plates at the large-head material hole inlet and the small-head material outlet respectively completely expose the large-head material hole and the small-head material hole.

[0018] Advantages of this solution: This solution arranges the materials into a parallel single column and outputs them into the grooves of the temporary storage bracket through vibration. Through the design of the large-head feeding hole, small-head feeding hole, and material baffle on the material turning cylinder, the materials with the small head facing forward are first screened into the material turning cylinder, and then the materials with the large head facing forward are screened into the material turning cylinder through the large-head feeding hole. Due to the design that either the large-head material hole or the small-head material hole is a blind hole and the other is a through hole, finally, the rotation of the material turning cylinder makes the material always discharge with the large or small head facing downwards, realizing the correction of the material direction. This solution combines direction recognition and direction correction into one, with a simple structure, low cost, and is more suitable for miniaturization. Description of the Drawings

Combining Figure 5 As shown, a row of a number of large-end material holes 30 distributed axially and a row of a number of small-end material holes 29 distributed axially are provided on the side surface of the material turning cylinder 13. A number of large-end material holes 30 are blind holes, and a number of small-end material holes 29 are through holes penetrating the material turning cylinder 13. The two rotation fixed-point positions of the material turning cylinder 13 make the large-end material holes 30 and the small-end material holes 29 respectively correspond to the grooves on the temporary storage bracket 10 one by one. Two cylinder position sensors 14 are installed on the bracket, and the included angle between the two cylinder position sensors 14 is equal to the included angle between the large-end material holes 30 and the small-end material holes 29 (the included angle is 70° in this embodiment).

The three material flappers 31 are respectively slidably connected to the side wall of the material turning cylinder 13 at the ends of the large-end material holes 30 and the small-end material holes 29 along the axial direction of the material turning cylinder 13. The three springs 32 are respectively connected between the ends of the three material flappers 31 and the material turning cylinder 13.

The flapper state disk 34 is fixed on the mounting frame 2 and is concentric with the material turning cylinder 13. Combining Figure 8 As shown, two arc-shaped grooves 35 are provided on the edge of the end face of the flapper state disk 34 adjacent to the material turning cylinder 13. The depths of the two arc-shaped grooves 35 gradually decrease along the rotation direction of the material turning cylinder 13 and finally connect to the end face of the flapper state disk 34. The deepest positions of the two arc-shaped grooves 35 are respectively facing the temporary storage bracket 10 and vertically downward;

[0034] When the turnover cylinder 13 is in the initial position: the inlet of the small-end material hole 29 corresponds to the groove of the temporary storage bracket 10 one by one. The material baffle 31 at the inlet of the small-end material hole 29 blocks part of the small-end material hole 29. The end of the transmission column 33 at the inlet of the small-end material hole 29 is located at the deepest part of one of the arc grooves 35.

[0035] When the ends of the transmission columns 33 at the inlet of the large-end material hole 30 and the outlet of the small-end material rotate to the deepest parts of the arc grooves 35 respectively, the material baffles 31 at the inlet of the large-end material hole 30 and the outlet of the small-end material completely expose the large-end material hole 30 and the small-end material hole 29 respectively.

[0036] In this embodiment, both the disk position sensor 7 and the cylinder position sensor 14 adopt infrared sensors.

[0037] The specific implementation process is as follows: S1: Power on and reset and load materials: Adjust the LL-type indexing pin 20 to the lowest position limit hole 21 on the material trough 3 to keep it at an inclination angle, power on, and the feeding disk 4 is reset under the cooperation of the disk position sensor 7, the first sensor baffle 8, and the traction motor 26. The feeding disk 4 is adjusted to the horizontal 0-degree position and locked. At this time, the feeding disk 4 is connected to the material trough 3, and the turnover cylinder is adjusted to enter the first-stage lock under the cooperation of the cylinder position sensor 14, the second sensor baffle 15, and the turning motor 17; at this time, the small-end material hole 29 is at a 35-degree position with the horizontal, and the small-end material hole 29 is docked with the groove on the temporary storage bracket 10. At this time, the materials are loaded into the material trough 3;

[0038] S2: Sort materials: Start running, and the vibration motor 16 arranged at the bottom of the feeding disk 4 runs. The feeding disk 4 performs a reciprocating rotation motion of 0°-35° (locked for 2S)-0°-35° (locked for 2S)-0° under the cooperation of the disk position sensor 7, the first sensor baffle 8, and the traction motor 26. Through the action of the excitation force of the vibration motor 16, the materials are sorted into a single horizontal row and output to the temporary storage bracket 10. Subsequently, the feeding disk 4 returns to the 0° position and is locked to prevent subsequent materials from continuing to be transported;

[0039] S3: Identify and collect materials in the small-end direction: The vibration motor 16 arranged at the bottom of the temporary storage bracket 10 runs. The temporary storage bracket 10 relays the materials to the material baffle 31 at the inlet of the small-end material hole 29 of the turnover cylinder through the excitation force. The material baffle 31 at the inlet of the small-end material hole 29 blocks part of the small-end material hole 29. Only the first half of the materials with the small end in front are allowed to enter the small-end material hole 29, and the materials with the large end in front are blocked by the material baffle 31;

[0040] S4: Discharging in the direction of the small end: The turnover motor 17 drives the turnover cylinder to continue rotating by 70° and locks. During the rotation, the end of the transmission column 33 at the entrance of the small-end material hole 29 slides along the arc-shaped groove 35, and the material baffle 31 gradually slides to reduce the blocked range of the small-end material hole 29. When the end of the transmission column 33 at the entrance of the small-end material hole 29 slides to the end face of the baffle state disc 34, the small-end material hole 29 is completely exposed. The material with the small end in front gradually enters the small-end material hole 29 due to gravity. When the turnover cylinder rotates to the position where the transmission column 33 at the exit of the small-end material hole 29 falls into the deepest part of the arc-shaped groove 35 at the bottom, the material baffle 31 opens to completely expose the exit of the small-end material hole 29, and the small end of the material is vertically output downward;

[0041] S5: Collecting materials in the direction of the large end: After the turnover cylinder continues to rotate by 70° and locks, at this time, the large-end material holes 30 correspond to the grooves on the temporary storage bracket 10 one by one, and the material baffle 31 at the large-end material hole 30 completely exposes the large-end material hole 30. The temporary storage bracket 10 conveys the materials into the large-end material holes 30 of the turnover cylinder through the vibration force;

[0042] S6: Discharging in the direction of the large end: The turnover cylinder continues to rotate, and the material with the large end in front gradually enters the large-end material hole 30 due to gravity. When the turnover cylinder continues to rotate to the position where the transmission column 33 at the entrance of the large-end material hole 30 falls into the deepest part of the arc-shaped groove 35 at the bottom, the material baffle 31 opens, and the small end of the material is vertically output downward, completing the direction identification and correction of the materials.
