Description

Technical Field

[0001] This invention relates to the technical field of material conveying equipment, and in particular to a silo mechanism and a feeding method. Background Technology

[0002] Existing material conveying equipment mainly relies on manual handling and robotic arms to transport stacked boards one by one. The robotic arm drives a robotic hand or suction cup to transport the boards one by one. In this method, the robotic arm needs to complete the transport and reset of the previous board before transporting the next board. The conveying process is relatively complex and time-consuming, resulting in low board conveying efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a silo mechanism and a feeding method, wherein the silo mechanism can transport stacked boards one by one, thereby improving the conveying efficiency of the boards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] On the one hand, a hopper mechanism is provided, including:

[0006] Base;

[0007] The first clamping seat has a pivot portion and a first clamping portion located below the pivot portion;

[0008] as well as

[0009] A second clamping seat is mounted on the base; the second clamping seat has a second clamping portion;

[0010] The first clamping part and the second clamping part are arranged at intervals and a feeding channel extending from top to bottom is formed between the first clamping part and the second clamping part. The pivot part is rotatably mounted on the base so that the first clamping part can rotate in a direction close to or away from the second clamping part.

[0011] Optionally, the hopper mechanism further includes a first driver mounted on the base; the first driver is kinetically connected to the first clamping seat to cause the first clamping part to rotate in a direction close to or away from the second clamping part.

[0012] Optionally, the hopper mechanism further includes an elastic element; the first clamping seat is connected to the base through the elastic element, and the elastic element is used to apply elastic force to make the first clamping seat rotate in a direction away from the second clamping seat.

[0013] Optionally, the base is provided with a first positioning block and the first clamping seat is provided with a first positioning groove. When the first clamping seat rotates in a direction away from the second clamping seat, the first positioning block is located on the rotation path of the first positioning groove.

[0014] or

[0015] The base is provided with a second positioning groove and the first clamping seat is provided with a second positioning block. When the first clamping seat rotates in a direction away from the second clamping seat, the second positioning groove is located on the rotation path of the second positioning block.

[0016] Optionally, the second clamping seat is slidably disposed on the base so that the second clamping part moves in a direction close to or away from the first clamping part.

[0017] Optionally, the hopper mechanism further includes a second driver mounted on the base; the second driver is kinetically connected to the second clamping seat.

[0018] Optionally, the hopper mechanism further includes a bracket mounted on the base; the bracket is located below the feeding channel.

[0019] Optionally, the bracket includes a sliding plate and a tray mounted on the sliding plate; the sliding plate is slidably mounted on the base to be close to or away from the feeding channel.

[0020] Optionally, the pallet is rotatably mounted on the slide plate, the pallet has a receiving surface, and the pallet can switch between an unfolded position and a retracted position. When the pallet is in the unfolded position, the receiving surface is horizontally positioned below the feeding channel; when the pallet is in the retracted position, the receiving surface abuts against the base.

[0021] On the other hand, a feeding method is provided based on the above-mentioned hopper mechanism, including the following steps:

[0022] S10: Drive the pivot portion of the first clamping seat to rotate so that the first clamping portion moves closer to the second clamping portion, so that the width of the feeding channel decreases from top to bottom and the width of the lower end of the feeding channel is less than the width of the material.

[0023] S20: Stack the materials from bottom to top in the feeding channel;

[0024] S30: Drive the pivot portion of the first clamping seat to rotate so that the first clamping portion moves away from the second clamping portion, so that the width of the lower end of the feeding channel is greater than the width of the material.

[0025] S40: After the material at the bottom leaves the feeding channel from the lower end of the feeding channel, the pivot of the first clamping seat is driven to rotate so that the first clamping part moves closer to the second clamping part, so that the width of the lower end of the feeding channel is less than the width of the material, thus completing the conveying of one material.

[0026] S50: Repeat steps S30 to S40 until the material conveying volume reaches the preset value or until the material conveying is completed.

[0027] The beneficial effects of this invention are as follows: This hopper mechanism forms a feeding channel by setting a first clamping seat and a second clamping seat. After the plates are stacked and stored in the feeding channel, the first clamping part of the first clamping seat is driven to move along the direction close to the second clamping part, so that the first clamping part and the second clamping part jointly clamp the stacked plates. When it is necessary to transport the stacked plates, the first clamping part is driven to make alternating movements away from the second clamping part and closer to the second clamping part, so that the stacked plates can be transported one by one. After the previous plate falls, the next plate can be transported without waiting, thus improving the transport efficiency of the plates.

[0028] The feeding method of the present invention, by employing the above-mentioned hopper mechanism, can transport stacked boards one by one, thereby improving the conveying efficiency of the boards and thus improving the processing efficiency of the boards. Attached Figure Description

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0050] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0051] For ease of description, unless otherwise stated, the terms "up" and "down" in the following text refer to the same direction as "top" and "bottom". Figure 4 Its vertical direction is consistent with the horizontal direction mentioned below. Figure 4 Its left-right direction is consistent, and the front-back direction mentioned below is consistent with... Figure 4 Their projection directions are consistent.

[0052] like Figures 1 to 4As shown, this embodiment provides a hopper mechanism, including a base 11 and a first clamping seat 12 and a second clamping seat 13, both mounted on the base 11. The first clamping seat 12 has a pivot portion 122 and a first clamping portion 121 located below the pivot portion 122. The second clamping seat 13 has a second clamping portion 131.

[0053] The first clamping seat 12 and the second clamping seat 13 are arranged alternately from left to right, such that the first clamping portion 121 and the second clamping portion 131 are arranged alternately. The first clamping portion 121 is the side of the first clamping seat 12, and the second clamping portion 131 is the side of the second clamping seat 13. The first clamping portion 121 and the second clamping portion 131 are arranged opposite to each other. A feeding channel 14 extending from top to bottom is formed between the first clamping portion 121 and the second clamping portion 131. The pivot portion 122 of the first clamping seat 12 is rotatably mounted on the base 11, so that the first clamping portion 121 can rotate in a direction close to or away from the second clamping portion 131. When the pivot portion 122 of the first clamping seat 12 rotates relative to the base 11, the first clamping portion 121 can rotate along the direction of approaching or moving away from the second clamping portion 131, thereby changing the size of the feeding channel 14. When the first clamping portion 121 rotates along the direction of approaching the second clamping portion 131, the width of the feeding channel 14 in the horizontal direction gradually decreases from top to bottom, and the feeding channel 14 is V-shaped or approximately V-shaped. When the width of the lower end of the feeding channel 14 is less than the width of the plate, the plate cannot leave the feeding channel 14 from the lower end of the feeding channel 14. When the first clamping portion 121 rotates along the direction of moving away from the second clamping portion 131, making the width of the lower end of the feeding channel 14 greater than the width of the plate, the plate can leave the feeding channel 14 from the lower end of the feeding channel 14, thus realizing feeding. In use, the first clamping seat 12 is driven to rotate around the pivot 122 so that the first clamping part 121 rotates in a direction close to the second clamping part 131, thereby making the width of the lower end of the feeding channel 14 smaller than the width of the board, and the stacked boards are stored in the feeding channel 14. When it is necessary to transport the sheet material, the first clamping seat 12 is driven to rotate around the pivot 122 so that the first clamping part 121 rotates in a direction away from the second clamping part 131. When the width of the lower end of the feeding channel 14 is greater than the width of the sheet material, the bottom sheet material is disengaged from the lower end of the feeding channel 14. After the bottom sheet material is disengaged from the lower end of the feeding channel 14, the first clamping part 121 immediately rotates in a direction close to the second clamping part 131 so that the width of the lower end of the feeding channel 14 is less than the width of the sheet material. The first clamping part 121 and the second clamping part 131 jointly clamp the bottom sheet material in the feeding channel 14 at this time. When it is necessary to transport the next sheet material, the first clamping seat 12 is driven to rotate around the pivot 122 so that the first clamping part 121 rotates in a direction away from the second clamping part 131. By continuously repeating the above steps, the first clamping part 121 alternately moves away from and close to the second clamping part 131 to realize the sequential transport of the sheet material.Compared to traditional methods that use robotic arms to grip materials, the hopper mechanism in this embodiment can transport the boards one by one without the need for a robotic arm. The working process and structure of the hopper mechanism are simpler. At the same time, compared to traditional feeding equipment that requires waiting for a robotic arm to complete a process of gripping, feeding, unloading, and resetting, the feeding efficiency of this application is higher. After the previous board is delivered, the next board can be delivered immediately.

[0054] Combination Figure 1 and Figure 2 When the length of the sheet material to be conveyed is large, that is, the length of the sheet material along the rotation axis of the pivot 122 is large, two hopper mechanisms can be set up to cooperate in conveying the sheet material. The two hopper mechanisms are distributed in a mirror symmetrical manner and are arranged at intervals. The feeding channels 14 of the two hopper mechanisms are arranged opposite each other and are located in the area between the two hopper mechanisms. The two ends of the sheet material are clamped by the feeding channels 14 of the two hopper mechanisms respectively. The feeding of the sheet material is realized by driving the first clamping seat 12 of the two hopper mechanisms to rotate synchronously.

[0055] Furthermore, the second clamping seat 13 also has a guide portion 132 located above the second clamping portion 131. The guide portion 132 is an inclined surface located at the upper end of the second clamping seat 13, and the distance between the guide portion 132 and the first clamping seat 12 gradually increases from top to bottom. The guide portion 132 can guide the material to be placed into the feeding channel 14 from top to bottom.

[0056] Optionally, the base 11 includes a first support frame 111, a second support frame 112, a support plate 113, a mounting plate 114, a first shaft plate 115, and a second shaft plate 116. The first support frame 111 and the second support frame 112 are arranged at intervals, and the first support frame 111 is connected to the second support frame 112 through the support plate 113. The first shaft plate 115 and the second shaft plate 116 are arranged at intervals on the support plate 113, and the mounting plate 114 is mounted on the first shaft plate 115 or the second shaft plate 116. The mounting plate 114 is used for components such as the elastic element 18 and the first actuator 15.

[0057] In one embodiment, the hopper mechanism further includes a first driver 15 mounted on the base 11. The first driver 15 is kinetically connected to the first clamping seat 12 to rotate the first clamping part 121 in a direction approaching or away from the second clamping part 131. The first driver 15 can be driven by a motor connected to the pivot part 122 to rotate the first clamping seat 12, or it can be driven by a linear drive device such as a hydraulic cylinder, pneumatic cylinder, pneumatic telescopic rod, or lead screw module. In this embodiment, the first driver 15 is a pneumatic cylinder, which has the advantages of stable power output, higher reliability, low operating cost, and easy control. The pneumatic cylinder is mounted on the base 11 via a cylinder seat 21, and the output shaft of the pneumatic cylinder is connected to the first clamping seat 12.

[0058] Combination Figures 4 to 7 Optionally, the hopper mechanism also includes an elastic element 18. The elastic element 18 is a spring, and the first clamping seat 12 is connected to the base 11 via the elastic element 18. One end of the elastic element 18 is connected to the first clamping seat 12, and the other end is connected to the base 11. The elastic element 18 applies a spring force to cause the first clamping seat 12 to rotate in a direction away from the second clamping seat 13 and abut against the base 11. The elastic element 18 itself is in a stretched state, causing the first clamping portion 121 to tend to rotate away from the second clamping portion 131. When the first clamping portion 121 rotates in a direction closer to the second clamping portion 131, the elastic element 18 is further stretched. The spring applies a force to the first clamping seat 12, which is pulled towards the mounting plate 114 of the base 11. The first clamping seat 12 always tends to be close to the mounting plate 114 of the base 11, so that the first clamping seat 12 is kept in the open and released plate state, ensuring the feeding process. This can prevent the first clamping seat 12 from failing to spring back to the open and released plate state when the first driver 15 does not apply force, thereby preventing the plate and other materials from being locked in the feeding channel 14.

[0059] Furthermore, the mounting plate 114 of the base 11 is provided with a first hook seat 29, the first clamping seat 12 is provided with a second hook seat 30, and the mounting plate 114 of the base 11 is provided with a second mounting hole 119. One end of the elastic member 18 is connected to the first hook seat 29, and the other end of the elastic member 18 passes through the second mounting hole 119 and is connected to the first hook seat 29, which facilitates the installation of the elastic member 18.

[0060] Optionally, the pivot portion 122 of the first clamping seat 12 is rotatably mounted on the mounting plate 114. In this embodiment, when the first clamping seat 12 moves along the direction away from the second clamping seat 13 and approaches the mounting plate 114, the positioning methods of the first clamping seat 12 and the mounting plate 114 are as follows.

[0061] The first positioning method is as follows: the base 11 is provided with a first positioning block 117 and the first clamping seat 12 is provided with a first positioning groove 123. When the first clamping seat 12 rotates in a direction away from the second clamping seat 13, the first positioning block 117 is located on the rotation path of the first positioning groove 123.

[0062] The second positioning method is: the base 11 is provided with a second positioning groove and the first clamping seat 12 is provided with a second positioning block. When the first clamping seat 12 rotates in a direction away from the second clamping seat 13, the second positioning groove is located on the rotation path of the second positioning block.

[0063] In this embodiment, taking the first positioning method as an example, the mounting plate 114 of the base 11 is provided with a first positioning block 117, and the first clamping seat 12 is provided with a first positioning groove 123. When the first clamping seat 12 moves away from the second clamping seat 13 and approaches the mounting plate 114, the first clamping seat 12 is fitted onto the first positioning block 117 through the first positioning groove 123, so that the first clamping seat 12 and the mounting plate 114 are positioned together. When the hopper mechanism is conveying and releasing the plate, it uses the first clamping seat 12 and the mounting plate 114 to position the plate together, so as to prevent the first clamping seat 12 from moving along the rotation axis of the pivot part 122.

[0064] Optionally, to facilitate the installation of the second positioning block, the mounting plate 114 of the base 11 is provided with a first mounting hole 118. The first mounting hole 118 penetrates the mounting plate 114 of the base 11 in a horizontal direction. During installation, a part of the second positioning block is mounted on the outer side of the mounting plate 114 to facilitate the installation of the second positioning block. The remaining part of the second positioning block extends through the first mounting hole 118 and into the space between the first clamping seat 12 and the mounting plate 114 to achieve positioning.

[0065] Furthermore, when the first clamping seat 12 and the mounting plate 114 are positioned together, the bottom wall of the first positioning groove 123 abuts against the first positioning block 117 and there is a gap between the first clamping seat 12 and the mounting plate 114. The first positioning block 117 is made of flexible blocks such as silicone blocks, which can prevent the first clamping seat 12 from having a rigid collision with the mounting plate 114.

[0066] Combination Figure 1 and Figure 2In one embodiment, the second clamping seat 13 is slidably disposed on the base 11 so that the second clamping part 131 moves in a direction close to or away from the first clamping part 121. The second clamping seat 13 moves in a horizontal direction to approach or move away from the first clamping seat 12. Specifically, a guide rod 19 and a first lead screw 20 are mounted on the base 11. The two ends of the first lead screw 20 are rotatably mounted on the first shaft plate 115 and the second shaft plate 116, respectively. The second clamping seat 13 slides horizontally between the first shaft plate 115 and the second shaft plate 116. The guide rod 19 is an optical axis. There is at least one guide rod 19, and the two ends of the guide rod 19 are mounted on the first shaft plate 115 and the second shaft plate 116, respectively. In order to improve the smoothness of the sliding of the second clamping seat 13, there are two guide rods 19 in this embodiment, which are arranged at intervals from top to bottom. The first lead screw 20 is located between the two guide rods 19. The first lead screw 20 and the two guide rods 19 are parallel to each other. A nut block 25 is mounted on the first lead screw 20, a linear bearing 26 is mounted on the guide rod 19, and a bearing seat is mounted on the linear bearing 26. The bearing seat is connected to the nut block 25 via a connecting plate 27. A second clamping seat 13 is mounted on the connecting plate 27. The second clamping seat 13 and the connecting plate 27 are arranged sequentially along the radial direction of the first lead screw 20. When the first lead screw 20 is driven to rotate manually or by a power device such as a motor, the nut block 25 moves along the axial direction of the first lead screw 20, thereby driving the connecting plate 27 and the second clamping seat 13 on the connecting plate 27 to move. When the second clamping seat 13 moves away from or towards the first clamping seat 12, the width of the feeding channel 14 can be changed, so that the feeding channel 14 can be adapted to plates of different widths. Before feeding, the second clamping seat 13 is driven to move away from or close to the first clamping seat 12 according to the width of the plate, so that the first clamping seat 12 and the second clamping seat 13 jointly clamp the plate. Then the second clamping seat 13 remains stationary, and the plates are conveyed one by one by driving the first clamping seat 12 to rotate.

[0067] In one embodiment, the hopper mechanism further includes a second drive 16 mounted on the base 11. The second drive 16 is throttle-connected to the second clamping seat 13. The second drive 16 may be a power device such as a motor, or it may be a handwheel rotatably mounted on the base 11 and throttle-connected to the first lead screw 20.

[0068] Optionally, the hopper mechanism also includes a bracket 24 mounted on the base 11. The bracket 24 is located below the feeding channel 14. The bracket 24 is used to catch the sheet metal falling from the feeding channel 14.

[0069] Furthermore, the bracket 24 includes a sliding plate 241 and a pallet 242 mounted on the sliding plate 241. The pallet 242 is used to catch the plates falling from the feeding channel 14. The sliding plate 241 is slidably mounted on the base 11 to move closer to or further away from the feeding channel 14. By driving the sliding plate 241 to slide up and down, the pallet 242 moves closer to or further away from the lower end of the feeding channel 14, thereby adjusting the distance at which the pallet 242 catches the plates, thus adjusting the distance at which the plates fall and preventing excessive height differences that could damage the plates. At the same time, the position of the pallet 242 can be adjusted up and down according to the thickness of the plates, so that the distance between the pallet 242 and the lower end of the first clamping seat 12, and the distance between the pallet 242 and the lower end of the second clamping seat 13, is slightly greater than the thickness of one plate, thereby preventing multiple plates from falling onto the pallet 242 at the same time and enabling sequential conveying.

[0070] Understandably, once the pallet 242 receives the sheet material, a pushing device can be installed next to the pallet 242 to deliver the sheet material. For example, the pushing device includes a cyclically movable pulley, with several push rods spaced apart along the direction of the pulley's movement, each push rod sequentially pushing the sheet material.

[0071] Optionally, the hopper mechanism also includes a third drive 17, which is a device such as a cylinder, and the third drive 17 is connected to the slide plate 241 to drive the slide plate 241 to slide up and down.

[0072] Furthermore, in order to improve the stability of the sliding plate 241, the support plate 113 of the base 11 is provided with guide rails 22. There are two guide rails 22, which are arranged at intervals along the horizontal direction. A slider 23 is slidably mounted on the guide rails 22, and the sliding plate 241 is mounted on the slider 23.

[0073] Optionally, the pallet 242 is rotatably mounted on the slide plate 241. The pallet 242 has a receiving surface and can switch between an unfolded position and a retracted position. When the pallet 242 is in the unfolded position, the receiving surface faces upward and is horizontally positioned below the feeding channel 14. When the pallet 242 is in the retracted position, the receiving surface abuts against the base 11. Specifically, the pallet 242 is rotatably mounted on the upper end of the slide plate 241, and the rotation axis of the pallet 242 is horizontal. The pallet 242 rotates up and down relative to the base 11. When it is not necessary to catch the material, the pallet 242 flips upward, so that the receiving surface of the pallet 242 is close to and fits against the support plate 113 of the base 11, and the pallet 242 is in a vertical position, saving space. When it is necessary to catch the material, the pallet 242 flips downward, with the receiving surface facing upward and horizontally positioned below the feeding channel 14. When the tray 242 switches between the unfolded position and the stored position, the slide plate 241 slides up and down to avoid interference between the tray 242 and the first clamping seat 12 and the second clamping seat 13.

[0074] Combination Figure 2 and Figure 3 In one embodiment, the hopper mechanism further includes a counting component 28, which facilitates the adjustment of the height of the bracket 24. Specifically, the counting component 28 includes a position display 281, a second lead screw 282, an adjusting screw 283, an adjusting block 284, and a guide block 285. The position display 281, also known as a counter, records the travel distance of the second lead screw 282, facilitating the adjustment of the height of the adjusting block 284 and thus the adjustment of the rising height of the bracket 24. Two guide blocks 285 are spaced horizontally on the support plate 113. The second lead screw 282 is rotatably mounted between the two guide blocks 285, with its axis vertically aligned. The adjusting block 284 is slidably positioned between the two guide blocks 285 and threadedly connected to the second lead screw 282, allowing it to slide up and down along the lead screw 282. The position display 281 is mounted on the adjusting block 284. The adjusting screw 283 is installed on the support plate 113 and threadedly connected to the adjusting block 284. By rotating the adjusting screw 283, the adjusting block 284 can be driven to move the position display 281 up and down to abut against the bracket 24. This allows the position display 281 to obtain the height position of the bracket 24 based on the position of the second lead screw 2821 at this time, thus facilitating the adjustment of the maximum lifting height of the bracket 24.

[0075] This embodiment also provides a feeding method. Based on the hopper mechanism of any of the above embodiments, the feeding method includes the following steps:

[0076] S10: Drive the pivot 122 of the first clamping seat 12 to rotate so that the first clamping part 121 moves closer to the second clamping part 131, so that the width of the feeding channel 14 decreases from top to bottom and the width of the lower end of the feeding channel 14 is less than the width of the material.

[0077] S20: Stack the materials from bottom to top in the feeding channel 14;

[0078] S30: Drive the pivot 122 of the first clamping seat 12 to rotate so that the first clamping part 121 moves away from the second clamping part 131, so that the width of the lower end of the feeding channel 14 is greater than the width of the material.

[0079] S40: After the material at the bottom leaves the feeding channel 14 from the lower end of the feeding channel 14, the pivot part 122 of the first clamping seat 12 is driven to rotate so that the first clamping part 121 moves closer to the second clamping part 131, so that the width of the lower end of the feeding channel 14 is less than the width of the material, thus completing the conveying of one material.

[0080] S50: Repeat steps S30 to S40 until the material conveying volume reaches the preset value or until the material conveying is completed.
