Description

Technical Field

[0001] This application relates to the field of rejection device technology, and in particular to a flexible rejection mechanism and a flexible rejection device. Background Technology

[0002] The rejection devices for defective products on manufacturing lines mainly include two types: linear and oscillating. The oscillating flexible rejection device drives the rejection finger to oscillate 90 degrees, switching between being perpendicular to the conveyor track's transport direction and parallel to the track's support surface, and being perpendicular to the track's support surface. When the rejection finger is perpendicular to the conveyor track's transport direction and parallel to the support surface, the defective product leaves the conveyor track under the guidance of the rejection finger. When the rejection finger is perpendicular to the track's support surface, the rejection finger does not contact the product on the conveyor track, and the product can pass through the rejection station under the conveyor track's transport. However, because the rejection finger generates a large instantaneous impact force when oscillating and changing direction at high speed, it causes violent shaking, affecting the stability of the rejection finger and resulting in significant structural damage.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0041] Please refer to the following: Figures 1 to 4 In one aspect, embodiments of this application provide a flexible rejection mechanism 100 for rejecting defective products 400 on a conveyor track 300. Please refer to... Figure 5 and Figure 6The flexible rejection mechanism 100 includes rejection fingers 10, positioning members 20, and driving members 30. The positioning member 20 includes a support part 21 and a positioning part 22 connected to the support part 21. One end of the rejection finger 10 is rotatably connected to the support part 21. The positioning part 22 is provided with a buffer member, which is used to abut against the rejection finger 10 when the rejection finger 10 rotates to a preset angle. The driving member 30 is connected to the rejection finger 10 and is used to drive the rejection finger 10 to rotate relative to the support part 21. There are multiple rejection fingers 10 and multiple driving members 30. The multiple rejection fingers 10 correspond one-to-one with the multiple driving members 30, and the multiple rejection fingers 10 are arranged at intervals along the conveying direction of the conveying track 300.

[0042] In this way, by setting multiple rejection fingers 10 to be arranged at intervals along the conveying direction of the conveying track 300, the defective products 400 can be flexibly rejected. At the same time, by setting the positioning part 22 to limit the rotation angle of the rejection fingers 10, the stability of the rejection fingers 10 can be improved. By setting a buffer on the positioning part 22 to abut against the rejection fingers 10 when the rejection fingers 10 rotate to a preset angle, the instantaneous impact force of the rejection fingers 10 when changing direction can be absorbed and reduced, the vibration of the rejection fingers 10 can be suppressed, and the effect of buffering and shock absorption can be achieved, thereby further improving the stability of the rejection fingers 10, reducing the structural loss of the flexible rejection mechanism 100, and also buffering the movement of the rejection fingers 10 to reduce the instantaneous impact of the rejection fingers 10 on the positioning part 22, so as to protect the rejection fingers 10 and the positioning part 20 and reduce the structural loss when the rejection fingers 10 collide with the positioning part 22.

[0043] In some embodiments, the conveying track 300 has a support surface for supporting products, the positioning part 22 has a first surface 221 and a second surface 222 opposite to each other, and the buffer includes a first buffer 40 and a second buffer 50. The first buffer 40 is disposed on the first surface 221, and the second buffer 50 is disposed on the second surface 222. The first buffer 40 is used to abut against the rejecting finger 10 when the rejecting finger 10 rotates to be parallel to the support surface of the conveying track 300 and perpendicular to the conveying direction of the conveying track 300, and the second buffer 50 is used to abut against the rejecting finger 10 when the rejecting finger 10 rotates to be perpendicular to the support surface of the conveying track 300.

[0044] By providing a first buffer 40 and a second buffer 50 on two opposite surfaces of the positioning part 22, the rejecting finger 10 can receive buffer support when changing directions. This ensures that the instantaneous impact force generated by the rejection finger 10 due to direction change can be transmitted to the first buffer 40 and the second buffer 50. The first buffer 40 and the second buffer 50 buffer and dampen the rejection finger 10, thereby improving the stability of the rejection finger 10 and reducing structural damage to the flexible rejection mechanism 100. Furthermore, since the buffers are only provided on two opposite surfaces of the positioning part 22, the area of ​​the buffers can be reduced while ensuring the buffering effect, which helps to reduce the cost and weight of the flexible rejection mechanism 100.

[0045] It should be noted that the preset angle refers to the angle formed between the length direction of the rejecting finger 10 and the bearing surface of the conveying track 300 after the rejecting finger 10 changes direction by rotation. That is, when the rejecting finger 10 rotates to be parallel to the bearing surface of the conveying track 300 and perpendicular to the conveying direction of the conveying track 300, the preset angle is 0 degrees, and when the rejecting finger 10 rotates to be perpendicular to the bearing surface of the conveying track 300, the preset angle is 90 degrees.

[0046] Optionally, the materials of the first buffer 40 and the second buffer 50 can be any one of silicone, rubber, sponge, expanded polypropylene (EPP) plastic foam, or steel plate, etc. The specific materials can be set according to actual needs, and there are no restrictions here.

[0047] Please combine Figures 6 to 8 In some embodiments, the finger 10 includes a finger portion 11, a rotating portion 12, a first limiting portion 13, and a second limiting portion 14. The rotating portion 12 is connected to one end of the finger portion 11 and is rotatably connected to the support portion 21. The first limiting portion 13 is connected to the side of the rotating portion 12 away from the finger portion 11 and extends along the length direction of the finger portion 11. The second limiting portion 14 is connected to the side of the rotating portion 12 away from the first limiting portion 13, and the extension direction of the second limiting portion 14 is perpendicular to the length direction of the finger portion 11.

[0048] In this way, by setting the first limiting part 13 and the second limiting part 14 perpendicular to each other, not only can the rotation angle of the rotating part 12 be limited, but also after the removal finger 10 rotates and changes direction, it can abut against the first buffer 40 and the second buffer 50 respectively to achieve buffering and shock absorption of the removal finger 10. This ensures the reliability of the finger part 11 while improving the stability of the removal finger 10, thereby improving the reliability of the removal finger 10 and avoiding damage to the finger part 11 caused by the finger part 11 abutting against the first buffer 40 and the second buffer 50, which would result in structural wear of the finger part 11.

[0049] Understandably, in other embodiments, the first buffer 40 and the second buffer 50 may also be disposed on two adjacent surfaces of the positioning part 22, and the rejecting finger 10 is divided into two parts by the rotation axis, with the two parts of the rejecting finger 10 respectively abutting against the first buffer 40 and the second buffer 50.

[0050] Optionally, as described above, multiple rejection fingers 10 are sequentially and spaced apart along the conveying direction of the conveying track 300. Based on this, the flexible rejection mechanism 100 also includes a first rotating shaft 60, which is fixedly installed on the support part 21. Each rejection finger 10's rotating part 12 is provided with a first movable hole 120. The first rotating shaft 60 passes through the first movable hole 120 of each rotating part 12 and is rotatable relative to the first movable hole 120. This allows each rejection finger 10 to rotate relative to the first rotating shaft 60, thereby improving the flexibility of the flexible rejection mechanism 100. At the same time, by restricting the rotation origin of multiple rejection fingers 10 through the first rotating shaft 60, multiple rejection fingers 10 rotate around the axis of the first rotating shaft 60 to achieve direction changes, thereby improving the reliability of the rejection finger 10 rotation. Under the premise of the same rotation angle, the flatness of multiple rejection fingers 10 can be improved, thereby improving the rejection effect on non-conforming products 400.

[0051] Optionally, there are two support parts 21. The two support parts 21 are provided with a fixing groove 210 through them along the conveying direction of the conveying track 300. The fixing groove 210 has an opening on the side away from the positioning part 22. The two ends of the first rotating shaft 60 are respectively fastened to the fixing groove 210 of the two support parts 21 by fasteners.

[0052] In this way, by setting two support parts 21, not only can multiple rejection fingers 10 be supported, allowing the rejection fingers 10 to rotate relative to the support parts 21, but structural limits can also be provided for the multiple rejection fingers 10 to improve the structural reliability of the rejection fingers 10. At the same time, by setting a fixing groove 210 with an opening, the first rotating shaft 60 can be easily disassembled and fixed, which is beneficial to the replacement and maintenance of the first rotating shaft 60.

[0053] Understandably, in other embodiments, the plurality of rejection fingers 10 may also be rotatably connected by the engagement of the shaft holes of two adjacent rejection fingers 10.

[0054] In some embodiments, the lengths of the finger portions 11 of the plurality of rejection fingers 10 gradually increase along the conveying direction of the conveying track 300. This allows the plurality of rejection fingers 10 to rotate to a position perpendicular to the conveying direction of the conveying track 300 and parallel to the supporting surface, forming an inclined or arc-shaped surface that can be used to guide products away from the conveying track 300, thereby facilitating the guidance of defective products away from the conveying track 300. On the other hand, it also facilitates ensuring that the lengths of the drive members 30 corresponding to the plurality of rejection fingers 10 are the same or approximately the same, thus simplifying the selection and installation of the drive members 30.

[0055] Optionally, considering that the smaller the spacing between the multiple rejection fingers 10, the stronger the continuity of the guiding surface (sloping or arc-shaped surface) formed by the multiple rejection fingers 10 for guiding the product away from the conveyor track 300, it is beneficial to guide the product away from the conveyor track 300, so that the movement of the product is smooth when rejecting the unqualified product 400, and the product is avoided from getting stuck on the conveyor track 300. However, since the size of the driving member 30 is larger than the size of the rejection fingers 10, if one driving member 30 is to drive the movement of one rejection finger 10, then when the multiple driving members 30 are arranged in a straight line with intervals, the two adjacent rejection fingers 10 need to have a large spacing, which leads to a decrease in rejection reliability. Based on this, the first limiting part 13 of one of the rejection fingers 10 of the two adjacent rejection fingers 10 is connected to the driving member 30, and the second limiting part 14 of the other rejection finger 10 is connected to the driving member 30.

[0056] In this way, two adjacent rejection fingers 10 are connected to the drive unit 30 at different positions, which helps to make the two adjacent drive units 30 staggered in space, so as to make reasonable use of space and improve the compactness of space. This ensures that the two adjacent rejection fingers 10 have a small gap, while meeting the design requirement that one drive unit 30 corresponds to one rejection finger 10. That is, it can ensure the smoothness of the product movement when rejecting unqualified products 400, and improve the flexibility of the rejection fingers 10 movement.

[0057] Optionally, the driving member 30 is rotatably connected to the first limiting part 13 or the second limiting part 14. This allows the connection between the driving member 30 and the first limiting part 13 or the second limiting part 14 to rotate as needed when the driving member 30 drives the first limiting part 13 or the second limiting part 14 to move, thereby ensuring the structural reliability of the flexible rejection mechanism 100.

[0058] Optionally, one of the two adjacent rejection fingers 10 has a first limiting portion 13 with a first connecting groove 130, and the other rejection finger 10 has a second limiting portion 14 with a second connecting groove 140. A second rotating shaft 70 is installed in the first connecting groove 130 and the second connecting groove 140. The driving member 30 has a connecting hole, and the second rotating shaft 70 can rotatably pass through the connecting hole. This allows for a rotatable connection between the driving member 30 and the first limiting portion 13 and the second limiting portion 14.

[0059] Understandably, in other embodiments, the drive member 30 may also be connected to the first limiting part 13 and the second limiting part 14 via a hinge or universal joint.

[0060] Optionally, the positioning member 20 further includes a fixing part 23, which is connected to the positioning part 22 and the support part 21 and is located on the side of the positioning part 22 away from the rejection finger 10. The fixing part 23 has a plurality of first mounting grooves 231 on the side near the first surface 221 and a plurality of second mounting grooves 232 on the side near the second surface 222. The first mounting grooves 231 and the second mounting grooves 232 are staggered along the direction from the first surface 221 to the second surface 222. The positioning part 22 is located between the first mounting grooves 231 and the second mounting grooves 232, and the driving member 30 passes through the first mounting groove 231 or the second mounting groove 232.

[0061] In this way, by setting the first mounting groove 231 and the second mounting groove 232, the drive member 30 can be driven to rotate the rejection finger 10, and the drive member 30 can be limited to avoid the rejection finger 10 being displaced relative to the conveying track 300 due to the vibration caused by the rejection finger 10 changing direction.

[0062] Please combine Figure 4 , Figure 5 as well as Figure 9 In some embodiments, the flexible rejection mechanism 100 further includes an anti-wear pad 80, which is installed between two adjacent rejection fingers 10. This reduces the kinematic wear between two adjacent rejection fingers 10, thereby improving the structural reliability of the rejection fingers 10.

[0063] Optionally, as described above, the rejecting finger 10 rotates around the axis of the first rotating shaft 60. Based on this, the anti-wear pad 80 is sleeved on the outer periphery of the first rotating shaft 60, and the anti-wear pad 80 is provided with a third mounting groove 81. The third mounting groove 81 has a first opening, and the positioning part 22 and the buffer member extend into the third mounting groove 81 through the first opening and engage with the anti-wear pad 80. This reduces the motion wear between two adjacent rejecting fingers 10 and prevents the anti-wear pad 80 from being rotated relative to the rotating shaft by the airflow generated by the movement of the rejecting finger 10, ensuring the structural stability of the anti-wear pad 80 relative to the positioning member 20. This creates a movement space between two adjacent anti-wear pads 80 for the rejecting finger 10 to change direction, thereby limiting the rejection finger 10 by the two adjacent anti-wear pads 80 and preventing displacement of the rejecting finger 10 due to vibration caused by changing direction, which would affect the rejection effect of the defective product 400.

[0064] In some embodiments, the drive element 30 may be any one of a cylinder, linear motor, hydraulic motor or ball screw, etc., and can be set according to actual needs, without limitation here.

[0065] Please combine Figure 1 and Figure 10 Secondly, this application also provides a flexible rejection device 200, including the flexible rejection mechanism 100 as described in the first aspect above.

[0066] It is understood that since the flexible rejection device 200 includes the flexible rejection mechanism 100 described in the first aspect, the flexible rejection device 200 has the beneficial effects of the flexible rejection mechanism 100 described in the first aspect, which will not be repeated here.

[0067] In some embodiments, the flexible rejection device 200 further includes a support platform 201 and an adjustment mechanism 202. The fixing part 23 of the positioning member 20 is installed on the support platform 201, and one end of the adjustment mechanism 202 away from the ground is connected to the support platform 201. The adjustment mechanism 202 is used to adjust the height or horizontal position of the support platform 201.

[0068] In this way, by adjusting the height of the support platform 201 through the adjustment mechanism 202, the height of the flexible rejection mechanism 100 relative to the conveyor track 300 can be adjusted, thereby adjusting the force position of the product when the flexible rejection mechanism 100 rejects the defective product 400, which helps to improve the stability of the product. By adjusting the horizontal position of the support platform 201 through the adjustment mechanism 202, the horizontal distance between the flexible rejection mechanism 100 and the product can be adjusted, which helps to reduce the extension size of the rejection finger 10 when rejecting the defective product 400, thereby reducing power consumption, lowering costs, and improving the reliability of the movement of the rejection finger 10.

[0069] Optionally, the adjustment mechanism 202 includes a height adjustment module and a horizontal displacement module, which are respectively connected to the bottom of the support platform 201, thereby realizing the adjustment of the height or horizontal position of the support platform 201.

[0070] Understandably, the height adjustment module and the horizontal displacement module can work simultaneously to adjust the height and horizontal position of the support platform 201 at the same time.

[0071] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
