Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of material separation, and more specifically to apparatus and methods for separating materials. Background Technology

[0002] In the food processing industry, strip-shaped materials such as sausages, spicy strips, and instant noodle forks are typically conveyed by conveyors and picked up by robotic arms during transport for further processing. However, since the incoming materials are often placed in boxes or baskets in a disordered state, they must be separated before being placed on the conveyor belt. In the current market, material separation poses a challenge for food manufacturers.

[0003] Vibratory feeders are commonly used to separate disordered strips of material (especially for instant noodles). However, this material separation mechanism has many drawbacks and is difficult to meet the needs of automated production. For example, the material separation speed of vibratory feeders is relatively slow. To meet actual production needs, 4-5 vibratory feeders are usually required to operate simultaneously. Furthermore, vibratory feeders have poor adaptability. When separating different types of materials, it is usually necessary to replace the vibratory feeder discs. Since the discs of vibratory feeders are typically heavy, replacing them consumes a lot of time and effort. In addition, the material to be separated may sometimes get stuck in the vibratory feeder, requiring manual intervention from the operator, thus negatively impacting production efficiency. Moreover, vibratory feeders also suffer from large surface area and high noise levels.

[0004] Therefore, a technical solution for separating materials is needed that can better meet the needs of automated production. Summary of the Invention

[0005] In view of the foregoing problems, various exemplary embodiments of this disclosure provide an apparatus and method for separating materials to improve the efficiency and adaptability of material separation.

[0006] In a first aspect of this disclosure, an exemplary embodiment provides an apparatus for separating materials, comprising: a material receiving plate arranged to receive materials to be separated; a first pair of support members coupled to opposite sides of the material receiving plate via respective rocker arms; a second pair of support members coupled to opposite sides of the material receiving plate via respective rocker arms and spaced apart from the first pair of support members; a drive mechanism including a rotatable output shaft; and a transmission mechanism arranged between the output shaft and the material receiving plate, and comprising: a cam arranged on the output shaft and rotatable together with the output shaft; a connecting seat arranged on the material receiving plate; and a connecting rod coupled at a first end to the cam and at a second end opposite to the first end to the connecting seat.

[0007] In some embodiments, the drive mechanism includes a motor; and a reducer coupled to the motor, wherein an output shaft is arranged on the reducer.

[0008] In some embodiments, the output shaft is provided with a protrusion at its outer periphery, and the cam includes a first mounting hole for inserting the output shaft and a recess for cooperating with the protrusion at the inner wall of the first mounting hole.

[0009] In some embodiments, the connecting rod includes: a first body portion; a first pin disposed on the first body portion via a hinge at a first end of the connecting rod, the first pin being coupled to a cam; and a second pin disposed on the first body portion via a hinge at a second end of the connecting rod, the second pin being coupled to a connecting seat.

[0010] In some embodiments, the cam includes a second mounting hole located at a distance from the output shaft, and a first pin is inserted into the second mounting hole.

[0011] In some embodiments, the material receiving plate includes: a sieve plate having a top side configured to receive material to be separated and a bottom side opposite the top side; a first mounting plate disposed on the bottom side of the sieve plate and coupled to a first pair of support members via respective rocker arms; and a second mounting plate disposed at a distance from the first mounting plate on the bottom side of the sieve plate and coupled to a second pair of support members via respective rocker arms.

[0012] In some embodiments, the sieve plate includes a plurality of ribs arranged in parallel on the top side of the sieve plate.

[0013] In some embodiments, each of the first mounting plate and the second mounting plate includes: a support portion coupled to the bottom side of the screen plate to support the screen plate; and a pair of mounting portions respectively arranged at both ends of the support portion and coupled to a corresponding pair of support members via a corresponding rocker arm.

[0014] In some embodiments, the connector is disposed on the support portion of the first mounting plate.

[0015] In some embodiments, the height of the second pair of support members is lower than the height of the first pair of support members, so that the material receiving plate is tilted.

[0016] In some embodiments, each rocker arm includes: a second body portion; a third pin disposed on the second body portion via a hinge at one end of the second body portion, the third pin being coupled to a corresponding pair of support members in a first pair of support members and a second pair of support members; and a fourth pin disposed on the second body portion via a hinge at the other end of the second body portion, the fourth pin being coupled to a material receiving plate.

[0017] In a second aspect of this disclosure, exemplary embodiments provide a method for separating materials using the apparatus according to a first aspect of this disclosure. The method includes: receiving materials to be separated on a material receiving plate; and rotating the output shaft of a drive mechanism to drive the material receiving plate upward, downward, forward, and backward via a transmission mechanism to separate the materials on the material receiving plate.

[0018] According to various embodiments of the invention, the cam can rotate together with the output shaft of the drive mechanism, thereby driving the connecting rod to achieve continuous reciprocating motion. The connecting rod then drives the material receiving plate to repeatedly move upward, downward, forward, and backward. In this way, the materials placed on the material receiving plate can be substantially separated from each other.

[0019] Compared to traditional vibratory feeders, the separation device according to embodiments of this disclosure will have a higher material separation speed due to the up-and-down and back-and-forth movement of the material receiving plate, thereby meeting the needs of automated production.

[0035] The principles of this disclosure will now be described with reference to several exemplary embodiments illustrated in the accompanying drawings. Although exemplary embodiments of this disclosure are shown in the drawings, it should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement this disclosure, and not to limit the scope of this disclosure in any way.

[0037] Unless otherwise specified or limited, the terms “installation,” “connection,” “support,” and “couplement,” and their variations, are used extensively and cover both direct and indirect installations, connections, supports, and couplings. Furthermore, “connection” and “couplement” are not limited to physical or mechanical connections or couplings. In the following description, the same reference numerals and designations are used to describe the same, similar, or corresponding parts in the drawings. Other explicit and implicit definitions may be included below.

[0038] As mentioned above, the material separation speed of a conventional vibratory feeder is relatively slow. According to embodiments of this disclosure, to improve material separation efficiency, a transmission mechanism with a specific configuration is arranged between the drive mechanism and the material receiving plate to drive the material receiving plate to move upward, downward, forward, and backward. As will be described in detail in the following paragraphs, the above idea can be implemented in various ways.

[0039] In the following text, reference will be made to Figures 1 to 10 The principles of this disclosure will be described in detail below. First, refer to... Figure 1 and Figure 2 , Figure 1 A perspective view of an apparatus 100 for separating materials according to an embodiment of the present disclosure, viewed along one direction, is shown. Figure 2 As shown Figure 1 The device 100 shown is viewed in three-dimensional form from different directions. (See also:) Figure 1 and Figure 2 As shown, the device 100 described herein typically includes a material receiving plate 6, a first pair of support members 21, a second pair of support members 22, a drive mechanism 1, and a transmission mechanism 30. The material receiving plate 6 is arranged to receive material to be separated on its upper surface. The support members 21 and 22 are arranged to support the material receiving plate 6 via corresponding rocker arms 7. The transmission mechanism 30 is arranged between the drive mechanism 1 and the material receiving plate 6 to transmit motion from the drive mechanism 1 to the material receiving plate 6.

[0040] In one embodiment, such as Figure 1 and Figure 2 As shown, the material receiving plate 6 is typically rectangular in shape and includes a first side, a second side, a third side, and a fourth side 601, 602, 603, and 604. The first side 601 is opposite to the second side 602, and the third side 603 is opposite to the fourth side 604. During the material separation process, the material to be separated can be placed on the upper surface of the material receiving plate 6 via a centrifuge, elevator, or other material supply equipment.

[0041] Support members 21 and 22 can be arranged on a workbench, on the ground, or in various other locations. One support member of the first pair of support members 21 is coupled to a first side 601 of the material receiving plate 6 via a corresponding swing arm 7, and the other support member of the first pair of support members 21 is coupled to a second side 602 of the material receiving plate 6 via a corresponding swing arm 7. Similarly, one support member of the second pair of support members 22 is coupled to a first side 601 of the material receiving plate 6 via a corresponding swing arm 7, and the other support member of the second pair of support members 22 is coupled to a second side 602 of the material receiving plate 6 via a corresponding swing arm 7. The second pair of support members 22 is spaced apart from the first pair of support members 21. In other words, the second pair of support members 22 is arranged at a different location than the first pair of support members 21 along the first and second sides 601, 602 of the material receiving plate 6.

[0042] Each swing arm 7 is coupled at one end to a corresponding pair of support members 21 and 22, and at the other end to a material receiving plate 6. With this arrangement, the material receiving plate 6 can swing relative to the support members 21 and 22 when driven by the drive mechanism 1 via the transmission mechanism 30.

[0043] like Figure 1 and Figure 2 As shown, the drive mechanism 1 is arranged on the third support member 23 and includes a rotatable output shaft 10. When the drive mechanism 1 is energized, the output shaft 10 will rotate in a predetermined direction. A transmission mechanism 30 is arranged between the output shaft 10 of the drive mechanism 1 and the material receiving plate 6 to drive the material receiving plate 6 when the drive mechanism 1 is in operation.

[0044] The transmission mechanism 30 includes a cam 3, a connecting seat 5, and a connecting rod 4. The cam 3 is arranged on the output shaft 10 and can rotate with it. The connecting seat 5 is arranged on the material receiving plate 6. The connecting rod 4 is coupled to the cam 3 at its first end and to the connecting seat 5 at its second end opposite to the first end, so as to transmit motion from the drive mechanism 1 to the material receiving plate 6. With this arrangement, the cam 3 can rotate with the output shaft 10 of the drive mechanism 1, thereby driving the connecting rod 4 to achieve continuous reciprocating motion. The connecting rod 4 then drives the material receiving plate 6 to oscillate relative to the support members 21 and 22, i.e., to repeatedly move upward, downward, forward, and backward. In this way, the materials placed on the material receiving plate 6 can be effectively separated from each other, meeting the needs of automated production.

[0045] In one embodiment, such as Figure 1 and Figure 2As shown, the height of the second pair of support members 22 is lower than the height of the first pair of support members 21, causing the material receiving plate 6 to tilt from the third side 603 to the fourth side 604. With this arrangement, the material to be separated can be placed on the upper surface of the material receiving plate 6 near the third side 603. As the material receiving plate 6 moves repeatedly upward, downward, forward, and backward, the material can move toward the fourth side 604 of the material receiving plate 6 and can be delivered to the next stage, such as a conveyor.

[0046] It should be understood that, such as Figure 1 and Figure 2 The relationship between the heights of support members 21 and 22 shown is for illustrative purposes only and is not intended to limit the scope of this application. In some embodiments, the heights of support members 21 and 22 may have other relationships. For example, the heights of support members 21 and 22 may be approximately equal to each other, or the height of support member 21 may be lower than the height of support member 22.

[0047] Figure 3 An example structure of drive mechanism 1 is shown. As shown, drive mechanism 1 includes a motor 11 and a reducer 12 coupled to the motor 11. Output shaft 10 is arranged on reducer 12. Figure 1 and Figure 2 As shown, the reducer 12 is provided with a flange 13 suitable for mounting on the third support member 23. With this arrangement, when the motor 11 is energized, the reducer 12 can drive the output shaft 10 to rotate at a desired speed. It should be understood that... Figure 3 The construction of the drive mechanism 1 shown is for illustrative purposes only and is not intended to limit the scope of this application.

[0048] In some embodiments, such as Figure 3 As shown, the output shaft 10 has a protrusion 101 at its outer periphery. The protrusion 101 extends substantially along the length direction of the output shaft 10. Therefore, as Figure 4 As shown, the cam 3 includes a first mounting hole 31 for inserting the output shaft 10 and a recess 32 for cooperating with the protrusion 101. The recess 32 is formed on the inner wall of the first mounting hole 31. With this arrangement, when the output shaft 10 is inserted into the first mounting hole 31, the protrusion 101 can be positioned within the recess 32, causing the cam 3 and the output shaft 10 to rotate simultaneously. In other embodiments, the cam 3 may be mounted on the output shaft 10 in other ways. The scope of this application is not limited to this aspect.

[0049] In one embodiment, such as Figure 4 As shown, the cam 3 also includes a second mounting hole 33 located at a certain distance from the first mounting hole 31. The second mounting hole 33 will be coupled to the connecting rod 4, which will be discussed below. Figure 1-2 and Figure 5 Describe it.

[0050] Figure 5 An exemplary construction of connecting rod 4 is shown. (As shown) Figure 1-2 and Figure 5 As shown, the connecting rod 4 includes a first main body portion 40, a first pin 41, and a second pin 42. The first pin 41 is arranged on the first main body portion 40 via a hinge (not shown) at the first end of the connecting rod 4. The second pin 42 is arranged on the first main body portion 40 via a hinge (not shown) at the second end of the connecting rod 4. The first pin 41 is adapted to be coupled to the cam 3. For example, the first pin 41 can be inserted into the second mounting hole 33 and fixedly coupled to the cam 3. The second pin 42 is adapted to be coupled to the connecting seat 5. With this arrangement, when the output shaft 10 of the drive mechanism 1 drives the cam 3 to rotate, the cam 3 will drive the connecting rod 4 to achieve continuous reciprocating motion. At the same time, the first and second pins 41 and 42 will rotate relative to the first main body portion 40.

[0051] It should be understood that Figure 5 The configuration of the connecting rod 4 shown is for illustrative purposes only and is not intended to limit the scope of this application. For example, in some embodiments, the first pin 41 and the second pin 42 may be fixedly mounted on the first body portion 40. Thus, the first pin 41 can rotate relative to the cam 3, and the second pin 42 can rotate relative to the connecting seat 5. With this arrangement, the motion transmission between the drive mechanism 1 and the material receiving plate 6 can also be achieved via the connecting rod 4.

[0052] Figure 6 An example structure of the connector 5 is shown. As shown, the connector 5 includes a base portion 51 and a pair of connecting portions 52. The connecting portions 52 are arranged in parallel on the base portion 51. The base portion 51 is provided with a third mounting hole 511, which is adapted to mount the connector 5 to the material receiving plate 6 by fasteners such as screws. Each of the connecting portions 52 is provided with a fourth mounting hole 521, which is adapted to couple to the second pin 42 of the connecting rod 4. It should be understood that... Figure 6 The construction of the connector 5 shown is for illustrative purposes only and is not intended to limit the scope of this application. The connector 5 can have various structures.

[0053] Figure 7 An example structure of the material receiving plate 6 is shown. In one embodiment, such as... Figure 7 As shown, the material receiving plate 6 includes a sieve plate 63, a first mounting plate 61, and a second mounting plate 62.

[0054] like Figure 7As shown, the sieve plate 63 has a top side configured to receive material to be separated and a bottom side opposite the top side. A plurality of ribs 631 are arranged in parallel on the top side of the sieve plate 63. Each rib 631 extends from a third side 603 to a fourth side 604 of the material receiving plate 6. Therefore, a plurality of grooves 632 are provided between the ribs 631. With this arrangement, when the material receiving plate 6 repeatedly moves upward, downward, forward, and backward under the drive of the drive mechanism 1, the material on the top side of the sieve plate 63, especially strip-shaped material, can be effectively separated by the ribs 631 and the grooves 632.

[0055] like Figure 7 As shown, the sieve plate 63 is supported by first and second mounting plates 61 and 62. The first mounting plate 61 is arranged on the bottom side of the sieve plate 63. The first mounting plate 61 is adapted to be coupled to the first pair of support members 21 via corresponding rocker arms 7. The second mounting plate 62 is also arranged on the bottom side of the sieve plate 63 and spaced apart from the first mounting plate 61. The second mounting plate 62 is adapted to be coupled to the second pair of support members 22 via corresponding rocker arms 7.

[0056] In some embodiments, such as Figure 7 As shown, the first mounting plate 61 includes a support portion 611 and a pair of mounting portions 612. The support portion 611 is coupled to the underside of the screen plate 63 to support the screen plate 63. For example, the support portion 611 may be provided with a fifth mounting hole 613 adapted to couple the first mounting plate 61 to the screen plate 63 by means of fasteners. The mounting portions 612 are respectively arranged at both ends of the support portion 611 and adapted to be coupled to a corresponding pair of support members 21, 22 via corresponding rocker arms 7. For example, each mounting portion 612 may be provided with a sixth mounting hole 614 adapted to be coupled to a corresponding rocker arm 7.

[0057] In one embodiment, such as Figure 1-2 and Figure 7 As shown, the connector 5 is positioned on the first side 601 of the material receiving plate 6, near the material receiving plate 6, on the support portion 611 of the first mounting plate 61. However, this is merely an exemplary position and not a limitation on the position of the connector 5. In other embodiments, the connector 5 may be positioned near the center of the support portion 611 of the first mounting plate 61, near the second side 602 of the material receiving plate 6, or at other locations on the material receiving plate 6.

[0058] It should be understood that, such as Figure 7 The illustrated construction of the material receiving plate 6 is for illustrative purposes only and is not intended to limit the scope of this application. In other embodiments, the material receiving plate 6 may have other structures. For example, the material receiving plate 6 may be formed integrally rather than composed of several parts.

[0059] Figure 8 An example structure of the pendulum 7 is shown. In one embodiment, such as... Figure 1-2 and Figure 8 As shown, each lever 7 includes a second body portion 70, a third pin 71, and a fourth pin 72. The third pin 71 is arranged on the second body portion 70 via a hinge (not shown) located at one end of the second body portion 70. The fourth pin 72 is arranged on the second body portion 70 via a hinge (not shown) at the other end of the second body portion 70. The third pin 71 is adapted to be coupled to a corresponding pair of support members 21 and 22. The fourth pin 72 is adapted to be coupled to the material receiving plate 6. For example, as Figure 1-2 and Figure 7-8 As shown, the fourth pin 72 can be inserted into the sixth mounting hole 614 of the mounting plates 61 and 62 and fixedly mounted on the material receiving plate 6. With this arrangement, the material receiving plate 6 can swing relative to the support members 21 and 22 when driven by the drive mechanism 1 via the transmission mechanism 30.

[0060] It should be understood that, such as Figure 8 The configuration of the swing arm 7 shown is for illustrative purposes only and is not intended to limit the scope of this application. For example, in some embodiments, the third pin 71 and the fourth pin 72 may be fixedly mounted on the second body portion 70. Thus, the third pin 71 can rotate relative to a corresponding pair of support members 21 and 22, and the fourth pin 72 can rotate relative to the material receiving plate 6. With this arrangement, the swing of the material receiving plate 6 relative to the support members 21 and 22 can also be achieved.

[0061] Figure 9 and 10 In respectively, as Figure 1 The front and top views of the device 100 show the direction of material movement separated by the material receiving plate 6. As shown, the material to be separated is placed on the upper surface of the material receiving plate 6 near the first pair of support members 21. Since the height of the second pair of support members 22 is lower than the height of the first pair of support members 21, the material will move in the direction from support members 21 to support members 22, as indicated by the arrows.

[0062] According to various embodiments of the present invention, the cam 3 can rotate together with the output shaft 10 of the drive mechanism 1, thereby driving the connecting rod 4 to achieve continuous reciprocating motion. The connecting rod 4 then drives the material receiving plate 6 to move repeatedly upward, downward, forward, and backward. In this way, the materials placed on the material receiving plate 6 can be substantially separated from each other.

[0063] Compared with traditional vibratory feeders, the separation device 100 has a higher material separation speed due to the up-and-down and back-and-forth movement of the material receiving plate 6, which meets the needs of automated production.

[0064] Moreover, the separation device 100 is well adaptable to different types of materials. That is, the separation device 100 can be used to separate different types of materials, such as sausages, spicy strips, instant noodle forks, etc.

[0065] Furthermore, during the material separation process, the material can be fully separated on the material receiving plate 6 and transported to the next stage. Therefore, there is no risk of material getting stuck.

[0066] In addition, compared with traditional vibratory feeders, the separation device 100 has a smaller area and lower noise.

[0067] Embodiments of this disclosure also provide a method using the above-described, as shown in the references... Figure 1-10 The described device 100 is used to separate materials. The method includes receiving materials to be separated on a material receiving plate 6; rotating the output shaft 10 of a drive mechanism 1 to drive the material receiving plate 6 to move up and down and back and forth via a transmission mechanism 30, thereby separating the materials on the material receiving plate 6.
