[0062] Embodiment 1:

[0063] The present embodiment provides a reflow material rack for conveying a material box 200 in which materials are loaded. After the material box 200 is conveyed into the reflow material rack, an operator takes out the materials from the material box 200, and the material box 200 is automatically conveyed out of the reflow material rack for recovery.

[0064] Please refer to Figure 1-Figure 6The reflux rack includes a frame 100, a material taking platform 40, and a first conveyor line 10, a second conveyor line 20 and a line changing device 30 arranged on the frame 100, wherein the material taking platform 40 is used for material taking operations, and the operator can take the materials in the material box 200 onto the material taking platform 40, the first conveyor line 10 is inclined relative to the horizontal plane, and its lower end faces the material taking platform 40; the second conveyor line 20 is arranged below the first conveyor line 10, the second conveyor line 20 is inclined relative to the horizontal plane, and the inclination directions of the first conveyor line 10 and the second conveyor line 20 are opposite; the line changing device 30 is used to transfer the material box 200 sent out by the first conveyor line 10 to the upper end of the second conveyor line 20, and a box receiving surface 301 is provided on the line changing device 30, and the inclination angle of the box receiving surface 301 can be automatically adjusted to adapt to the inclination direction of the first conveyor line 10 and the second conveyor line 20.

[0065] Specifically, the material picking platform 40 is arranged on one side of the frame 100. For example, the material picking platform 40 can be installed on one side of the frame 100, and the first conveyor line 10, the second conveyor line 20 and the line changing device 30 are installed in the frame body of the frame 100. The height of the lower port of the first conveyor line 10 is slightly higher than the height of the material picking platform 40. When the line changing device 30 moves to the lower port of the first conveyor line 10, the height of the supporting box surface 301 of the line changing device 30 is close to the height of the material picking platform 40, which is convenient for the operator to pick up materials. During operation, the operator or the loading equipment puts the material box 200 into the upper port of the first conveyor line 10, and the material box 200 slides along the first conveyor line 10 toward the material picking platform 40. When the material box 200 slides out from the lower port of the first conveyor line 10, the line changing device 30 receives the material box 200. At this time, the material box 200 is located next to the material picking platform 40. The operator can take out the material from the material box 200 to the material picking platform 40. After the material is picked up, the line changing device 30 drives the material box 200 to move to the upper port of the second conveyor line 20, and the material box 200 slides out along the second conveyor line 20 to the lower port. When the line-changing device 30 moves between the first conveyor line 10 and the second conveyor line 20, the inclination angle of the box surface 301 can be automatically adjusted to adapt to the inclination direction of the first conveyor line 10 and the second conveyor line 20, that is, the inclination direction of the box surface 301 can be adjusted back and forth, so that the line-changing device 30 can be docked with the first conveyor line 10 and the second conveyor line 20 respectively when in different positions, ensuring that the material box 200 can flow along the first conveyor line 10, the line-changing device 30 and the second conveyor line 20 in sequence. In summary, the reflow material rack provided in this embodiment can solve the problems of loading and recycling the material box 200, improve the degree of automation, reduce working hours, and improve production efficiency.

[0066] For example, please refer to Figure 1-Figure 3The first conveyor line 10 includes a first roller 11 and a first guide rail 12 which are arranged in parallel with each other. Both the first roller 11 and the first guide rail 12 are arranged obliquely relative to the horizontal plane, wherein at least two first rollers 11 are arranged side by side, and the first roller 11 includes a plurality of first rollers distributed along its extension direction. First guide rails 12 are arranged on both sides of the first conveyor line 10, and a first guide block 13 is arranged at one end of the first guide rail 12 close to the upper port of the first conveyor line 10, and a first guide arc surface 14 which gradually expands outward is arranged on the first guide block 13. Specifically, after the material box 200 is put in from the upper port of the first conveyor line 10, it slides downward along the first roller 11, during which the first guide rails 12 arranged on both sides define the sliding track of the material box 200, and the arrangement of the first guide block 13 facilitates the introduction of the material box 200 to avoid the situation of the box being stuck.

[0067] For example, please refer to Figure 1-Figure 4 A first cross bar 101 and a second cross bar 102 are provided on the frame 100. The first cross bar 101 and the second cross bar 102 are both arranged in the horizontal direction. The height of the first cross bar 101 is higher than the height of the second cross bar 102. The first cross bar 101 fixes and supports a part of the first roller 11 close to the upper end of the first conveyor line 10, and the second cross bar 102 fixes and supports a part of the first roller 11 close to the lower end of the first conveyor line 10. The inclination angle of the first conveyor line 10 relative to the horizontal plane is determined by the support height difference between the first cross bar 101 and the second cross bar 102.

[0068] For example, please refer to Figure 1-Figure 4The reflux material rack also includes a material blocking assembly 50, which includes a material blocking driving member 51 and a movable blocking rod 52, wherein the body of the material blocking driving member 51 is installed on the frame 100, and the movable blocking rod 52 is installed on the output end of the material blocking driving member 51. Under the drive of the material blocking driving member 51, the movable blocking rod 52 can selectively extend from the lower port of the first conveying line 10 to block or release the material box 200 on the first conveying line 10. Specifically, the material blocking driving member 51 adopts a telescopic driving member such as a linear cylinder and an electric push rod, and its main body is rotatably connected to the first cross bar 101 through the first connecting rod 105. The middle part of the movable blocking rod 52 is rotatably arranged on the second cross bar 102 through the second connecting rod 106. The second cross bar 102 is provided with an avoidance groove 1021 for avoiding the movable blocking rod 52. One end of the movable blocking rod 52 is hinged to the output end of the material blocking driving member 51, and the other end is provided with a material blocking hook plate 53. When the material blocking driving member 51 telescopes, it drives the movable blocking rod 52 to rotate around the horizontal axis so that the material blocking hook plate 53 selectively extends from the lower port of the first conveyor line 10. In this embodiment, when the material blocking drive 51 retracts, the movable blocking rod 52 is provided with one end of a material blocking hook plate 53 which rotates upward, and the material blocking hook plate 53 rises from the bottom of the lower port of the first conveyor line 10, which can limit the material box 200 from sliding out of the lower port of the first conveyor line 10. After the line changing device 30 moves to the lower port of the first conveyor line 10, the material blocking drive 51 extends out, and the material blocking hook plate 53 retracts from the lower port of the first conveyor line 10 to allow the material box 200 to slide onto the line changing device 30.

[0069] For example, please refer to Figure 1-Figure 3 The second conveyor line 20 includes a second roller 21 and a second guide rail 22 which are arranged in parallel with each other. The second roller 21 and the second guide rail 22 are both arranged obliquely relative to the horizontal plane, wherein at least two second rollers 21 are arranged side by side, and the second roller 21 includes a plurality of second rollers distributed along its extension direction. Second guide rails 22 are arranged on both sides of the second conveyor line 20, and a second guide block 23 is arranged at one end of the second guide rail 22 close to the upper port of the second conveyor line 20. The second guide block 23 is provided with a second guide arc surface 24 which gradually expands outward. Specifically, after the material box 200 enters the upper port of the second conveyor line 20 from the line changing device 30, it slides downward along the second roller 21. During this period, the second guide rails 22 arranged on both sides define the sliding track of the material box 200. The arrangement of the second guide block 23 facilitates the introduction of the material box 200 to avoid the situation of the box being stuck.

[0070] For example, please refer to Figure 1-Figure 4The frame 100 is provided with a third crossbar 103 and a fourth crossbar 104, which are both arranged in the horizontal direction, and the height of the third crossbar 103 is higher than that of the fourth crossbar 104. The third crossbar 103 fixes and supports a portion of the second roller 21 close to the upper end of the second conveying line 20, and the fourth crossbar 104 fixes and supports a portion of the second roller 21 close to the lower end of the second conveying line 20. The inclination angle of the second conveying line 20 relative to the horizontal plane is determined by the support height difference between the third crossbar 103 and the fourth crossbar 104. Specifically, the third crossbar 103 is arranged directly below the second crossbar 102 and directly below the first crossbar 101.

[0071] Exemplarily, when the line-changing device 30 is located at the lower end of the first conveyor line 10, the height of the highest point of the box surface 301 is not higher than the height of the lowest point of the first roller 11, ensuring that the material box 200 on the first conveyor line 10 can slide onto the line-changing device 30. Furthermore, the height difference between the highest point of the box surface 301 and the lowest point of the first roller 11 does not exceed one-fifth of the height of the material box 200, and the horizontal spacing between the box surface 301 and the first roller 11 is less than half of the width of the material box 200 in the conveying direction, ensuring that the material box 200 can slide smoothly onto the line-changing device 30. Similarly, when the line-changing device 30 is located at the upper end of the second conveyor line 20, the height of the lowest point of the box surface 301 is not lower than the height of the highest point of the second roller 21, ensuring that the material box 200 on the line-changing device 30 can slide onto the second conveyor line 20. Furthermore, the height difference between the lowest point of the box surface 301 and the highest point of the second raceway 21 does not exceed one-fifth of the height of the material box 200, and the horizontal spacing between the box surface 301 and the second raceway 21 is less than half of the width of the material box 200 in the conveying direction, ensuring that the material box 200 can slide smoothly onto the second conveyor line 20.

[0072] As for the inclination angle of the line changing device 30, it can be set to be the same as the inclination angle of the first transmission line 10 or the second transmission line 20 based on the requirement of smoothness, or it can be set to be slightly larger or slightly smaller than the inclination angle of the first transmission line 10 or the second transmission line 20 based on the requirement of adjusting the transmission speed. The angle difference is preferably within 10°.

[0073] In this embodiment, when the line change device 30 is located at the lower end of the first conveyor line 10, the box surface 301 is coplanar with the conveying plane of the first conveyor line 10, and the material box 200 can slide smoothly from the first conveyor line 10 to the line change device 30, reducing the shaking of the material box 200 during the transfer process and improving reliability. Figure 2 and Figure 3When the line changing device 30 is located at the upper end of the second conveying line 20, the box surface 301 is coplanar with the conveying plane of the second conveying line 20, and the material box 200 can slide smoothly from the line changing device 30 to the second conveying line 20, thereby reducing the jitter of the material box 200 during the transfer process and improving reliability.

[0074] For example, the line changing device 30 can swing relative to the frame 100, so as to adjust the tilt direction of the box surface 301. Figure 3 , Figure 5 and Figure 6 The line changing device 30 includes a lifting platform assembly 31 and a swing seat 32. The lifting platform assembly 31 is used to drive the swing seat 32 to lift. The box surface 301 is arranged on the swing seat 32. The swing seat 32 is rotatably connected to the lifting platform assembly 31. The swing seat 32 can rotate around the horizontal axis to adjust the inclination angle of the box surface 301. Specifically, the lifting platform assembly 31 includes a lifting seat 312, two lifting driving members 311, a plurality of lifting guide rods 313 and a plurality of lifting guide sleeves 314, wherein the swing seat 32 is rotatably mounted on the lifting seat 312 through a swing shaft 321, and a plurality of lifting guide sleeves 314 are installed on both sides of the lifting seat 312. A plurality of lifting guide rods 313 arranged in the vertical direction are distributed on both sides of the frame 100. The lifting seat 312 can be lifted and lowered in the vertical direction relative to the frame 100 through the one-to-one sliding cooperation between the lifting guide sleeves 314 and the lifting guide rods 313. The lifting drive member 311 adopts a telescopic drive member such as a linear cylinder and an electric push rod. The lifting drive members 311 are installed on both sides of the lifting seat 312. The movable ends of the two lifting drive members 311 are respectively connected to the two sides of the lifting seat 312. The two lifting drive members 311 drive the lifting seat 312 and the swing seat 32 to rise and fall together through synchronous telescopic actions, so that the line changing device 30 can be connected to the first transmission line 10 and the second transmission line 20 respectively.

[0075] For example, please refer to Figure 5 and Figure 6 , the rotation axis of the swing seat 32 is eccentrically arranged relative to its center of gravity. The side of the swing seat 32 that is away from the first conveying line 10 and the second conveying line 20 has a greater weight relative to the rotation axis of the swing seat 32. Therefore, in a natural state, the side of the swing seat 32 that is close to the first conveying line 10 and the second conveying line 20 is always tilted upward. Specifically, when the swing seat 32 is located at the lower end of the first conveying line 10, under the action of gravity, the swing seat 32 is in a first state, and the first state is: the side of the swing seat 32 that is close to the first conveying line 10 is tilted, and in this state, the box surface 301 is coplanar with the conveying plane of the first conveying line 10.

[0076] For example, please refer to Figure 3 and Figure 4A reversing push rod 110 is also installed at the bottom of the frame 100. The reversing push rod 110 includes a connecting portion 111 and a pushing portion 112. The connecting portion 111 is arranged in the height direction, and its lower end is connected to the frame 100, and its upper end is connected to the pushing portion 112. The pushing portion 112 is extended in the horizontal direction and is arranged below the side of the swing seat 32 away from the first conveying line 10 and the second conveying line 20. When the swing seat 32 approaches the upper end of the second conveying line 20, the swing seat 32 can swing under the action of the pushing portion 112 of the reversing push rod 110 until the swing seat 32 is at the lowest point position completely docked with the upper end of the second conveying line 20, and the swing seat 32 swings to the second state. The second state is: the side of the swing seat 32 away from the second conveying line 20 is tilted, and in this state, the box surface 301 is coplanar with the conveying plane of the second conveying line 20.

[0077] Exemplarily, the height of the pushing portion 112 of the reversing push rod 110 is higher than the highest point of the second conveying line 20, and the pushing portion 112 is fixed. During the descent of the swing seat 32, such as when the swing seat 32 descends to the first preset position, the pushing portion 112 of the reversing push rod 110 can resist one end of the swing seat 32. At this time, the swing seat 32 continues to descend. Since one end of the swing seat 32 is resisted by the pushing portion 112 of the reversing push rod 110 at this time, the swing seat 32 can continuously change the inclination angle under the action of the pushing portion 112 during the continued descent of the swing seat 32. Until the swing seat 32 descends to the second preset position, the swing seat 32 swings to the second state: the side away from the second conveying line 20 is tilted, and in this state, the supporting box surface 301 is coplanar with the conveying plane of the second conveying line 20.

[0078] It can be seen that the swing seat 32 always maintains an inclination in the same direction as the first conveyor line 10 in the absence of external force. When it descends to the upper port of the second conveyor line 20, under the action of the pushing portion 112 of the reversing push rod 110, the swing seat 32 swings to the other side and remains in a state of being inclined in the same direction as the second conveyor line 20, thereby realizing adaptive adjustment of the inclination angle of the box surface 301. The design is ingenious and does not require additional power to drive the swing, thereby reducing equipment cost and control cost.

[0079] In some other embodiments, the reversing ejector 110 can also be configured as an actively retractable ejector structure. For example, the reversing ejector 110 can be composed of a linear drive member such as a linear cylinder or an electric push rod and an ejector structure. The driving end of the linear drive member is vertically arranged upward and connected to the ejector structure. Initially, the linear drive member is in a retracted state. When the swing seat 32 descends to the second preset position, the linear drive member drives the ejector structure to rise upward to push the side of the swing seat 32 away from the second transmission line 20, so that the swing seat 32 swings to the second state: the side away from the second transmission line 20 is tilted, and in this state, the box surface 301 is coplanar with the transmission plane of the second transmission line 20.

[0080] For example, please refer to Figure 5 and Figure 6 The swing seat 32 is provided with two line-changing rollers 322 arranged side by side and two line-changing guide plates 323 arranged at intervals. The line-changing rollers 322 and the line-changing guide plates 323 are arranged in parallel with each other. The line-changing rollers 322 are provided with a plurality of rollers distributed along the extension direction thereof, which are used to support the conveying material box 200. The line-changing guide plates 323 are used to limit the sliding track of the material box 200 on the line-changing rollers 322. Furthermore, both ends of the line-changing guide plates 323 are provided with guide parts 3231 extending outward gradually. The guide parts 3231 at both ends are arranged to facilitate the material box 200 to slide from the first conveying line 10 to the swing seat 32, and to slide from the swing seat 32 to the second conveying line 20, so as to avoid the occurrence of the box jam and improve the reliability.

[0081] For example, please refer to Figure 5 and Figure 6 Two material blocking blocks 33 are provided at the end of the swing seat 32 away from the first conveying line 10. The two material blocking blocks 33 are arranged side by side and spaced apart. The material blocking blocks 33 protrude upward from the supporting box surface 301 to prevent the material box 200 from sliding downward.

[0082] For example, the tilt angle of the swing seat 32 in the first state is adjustable to improve versatility. Figure 5 and Figure 6The line changing device 30 also includes an inclination adjustment component 34, which includes an adjustment drive 341 and an adjustment support block 342. The adjustment drive 341 is installed at the movable end of the lifting platform component 31, specifically fixedly installed on the lifting seat 312, and the adjustment support block 342 is installed at the output end of the adjustment drive 341. When the swing seat 32 is in the first state, the adjustment support block 342 supports the swing seat 32 away from the first transmission line 10. The adjustment drive 341 can change the position of the adjustment support block 342 to adjust the height or horizontal position of the swing seat 32 supported by the adjustment support block 342, thereby limiting the inclination angle of the swing seat 32 in the first state. In this embodiment, the adjustment drive 341 adopts a telescopic drive such as a linear cylinder and an electric push rod. The movable end of the adjustment drive 341 is vertically upwardly arranged. The adjustment drive 341 adjusts the height of the support block 342 through a telescopic action, thereby changing the height of the swing seat 32 supported by the adjustment support block 342. In other embodiments of the present invention, the adjusting driving member 341 may also be arranged horizontally, and the yaw angle may be adjusted by changing the horizontal distance between the adjusting support block 342 and the swing shaft 321. In some embodiments, the inclination adjustment assembly 34 may also adopt a power structure composed of a rotating driving member and a cam, and the height of the cam supporting the swing seat 32 may be adjusted by changing the angle of the cam.

[0083] Exemplarily, the tilt angle of the swing seat 32 in the second state is adjustable to improve versatility. Specifically, in some embodiments, the connecting portion 111 of the reversing push rod 110 can be set as a retractable sleeve rod structure, and the tilt angle of the swing seat 32 in the second state can be adjusted by changing the height of the push portion 112.

[0084] For example, please refer to Figure 1 and Figure 2 The material picking platform 40 includes a material picking platform 41, and the material picking platform 41 is provided with an avoidance gap 42 for avoiding the line changing device 30 and the material box 200. When the line changing device 30 is docked with the first conveyor line 10, the material box 200 protrudes from the avoidance gap 42 to the top of the material picking platform 41, so that the operator can pick up the material conveniently.

[0085] For further information, please refer to Figure 1 and Figure 2 A top frame 43 is provided above the material taking platform 41 , and lighting components 44 such as lamp tubes are installed on the top frame 43 . The lighting components 44 are arranged toward the material taking platform 41 to provide lighting for the material taking operation.

[0086] Embodiment 2:

[0087] like Figure 7 As shown, this embodiment provides a reflux conveying method, which is implemented by the reflux material rack provided in the first embodiment, and specifically includes the following steps:

[0088] Put the material box 200 into the upper end of the first conveyor line 10, slide the material box 200 downward along the first conveyor line 10 and slide out from the lower end of the first conveyor line 10;

[0089] The line changing device 30 moves to dock with the lower end of the first conveying line 10 , so that the receiving material box 200 of the first conveying line 10 is opened, so that the operator can take the material in the material box 200 to the material taking platform 40 ;

[0090] The line changing device 30 moves toward the direction close to the second conveying line 20 and adapts to the tilting direction of the second conveying line 20, automatically adjusting the tilting angle of the box receiving surface 301 to dock with the upper end of the second conveying line 20;

[0091] The material box 200 slides downward along the second conveying line 20 and slides out from the lower end of the second conveying line 20 .

[0092] Exemplarily, the line changing device 30 moves to dock with the lower end port of the first conveying line 10, specifically including:

[0093] During the rising process of the line changing device 30, the swing seat 32 is tilted on the side close to the first conveying line 10 under the action of gravity. When the line changing device 30 reaches the lower end of the first conveying line 10, the supporting box surface 301 is coplanar with the conveying plane of the first conveying line 10.

[0094] Exemplarily, the inclination angle of the box surface 301 is automatically adjusted to adapt to the inclination direction of the second conveyor line 20, specifically including: during the descent of the swing seat 32, the swing direction is changed under the action of the reversing push rod 110, so that the swing seat 32 is tilted away from the side of the second conveyor line 20, and the box surface 301 is coplanar with the conveying plane of the second conveyor line 20.

[0095] Exemplarily, before the material box 200 slides out from the lower port of the first conveyor line 10, the following steps are also included: the material blocking driving member 51 drives the movable blocking rod 52 to extend from the lower port of the first conveyor line 10 to block the material box 200 on the first conveyor line 10 from sliding out. After the line changing device 30 moves to dock with the lower port of the first conveyor line 10, the following steps are also included: the material blocking driving member 51 drives the movable blocking rod 52 to retract from the lower port of the first conveyor line 10 to allow the material box 200 on the first conveyor line 10 to slide out.

[0096] The reflux conveying method provided in this embodiment transfers the material box 200 between the first conveying line 10 and the second conveying line 20 through the line changing device 30. The box supporting surface 301 of the line changing device 30 can automatically adjust the inclination direction to adapt to the inclination direction of the first conveying line 10 and the second conveying line 20, so as to ensure that the material box 200 can flow along the first conveying line 10, the line changing device 30 and the second conveying line 20 in sequence, so as to solve the problem of loading and recycling the material box 200, improve the degree of automation, reduce working hours, and improve production efficiency.
