Description

Technical Field

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

[0002] Existing material conveying equipment mainly uses manual handling and robotic arms to transport stacked plates one by one. The robotic arm drives a manipulator or a suction cup to transport the plates one by one. This conveying method requires the robotic arm to complete the conveying of the previous plate and reset it when conveying the next plate. The conveying process is relatively complicated and time-consuming, and the conveying efficiency of the plates is low. Summary of the invention

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

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] In one aspect, a silo mechanism is provided, comprising:

[0006] Pedestal;

[0007] A first clamping seat, comprising a pivoting portion and a first clamping portion located below the pivoting portion;

[0008] as well as

[0009] A second clamping seat, 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 pivoting part is rotatably installed on the base so that the first clamping part rotates in a direction approaching or away from the second clamping part.

[0011] Optionally, the silo mechanism further comprises a first driver mounted on the base; the first driver is transmission-connected to the first clamping seat so as to rotate the first clamping portion in a direction approaching or away from the second clamping portion.

[0012] Optionally, the silo mechanism further includes an elastic member; the first clamping seat is connected to the base via the elastic member, and the elastic member is used to apply an elastic force to rotate the first clamping seat 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, and 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 to enable the second clamping portion to move in a direction approaching or away from the first clamping portion.

[0017] Optionally, the silo mechanism further comprises a second driver mounted on the base; the second driver is transmission-connected to the second clamping seat.

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

[0019] Optionally, the bracket includes a slide plate and a support plate mounted on the slide plate; the slide plate is slidably mounted on the base up and down to approach or move away from the feeding channel.

[0020] Optionally, the pallet is rotatably mounted on the slide, the pallet having a material receiving surface, the pallet switches between an expanded position and a stowed position, when the pallet is in the expanded position, the material receiving surface is horizontally arranged below the feeding channel; when the pallet is in the stowed position, the material receiving surface abuts against the base.

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

[0022] S10: driving the pivoting portion of the first clamping seat to rotate to drive the first clamping portion to approach 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 smaller than the width of the material;

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

[0024] S30: driving the pivoting portion of the first clamping seat to rotate to drive the first clamping portion to move 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 a material at the bottom leaves the feeding channel from the lower end of the feeding channel, the pivoting portion of the first clamping seat is driven to rotate to drive the first clamping portion to approach the second clamping portion, so that the width of the lower end of the feeding channel is smaller than the width of the material, thereby completing the conveying of a material;

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

[0027] The beneficial effects of the present invention are as follows: the silo 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 portion of the first clamping seat is driven to move in a direction close to the second clamping portion, so that the first clamping portion and the second clamping portion clamp the stacked plates together. When the stacked plates need to be transported, the first clamping portion is driven to move alternately away from the second clamping portion and close to the second clamping portion, so that the stacked plates are transported one by one. After the previous plate falls, the next plate can be transported without waiting, thereby improving the transport efficiency of the plates.

[0028] The feeding method of the present invention can transport the stacked plates one by one by adopting the above-mentioned silo mechanism, thereby improving the transport efficiency of the plates and further improving the processing efficiency of the plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In addition, it should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

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

[0051] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 4 The up and down directions are consistent with the left and right directions mentioned below. Figure 4 The left and right directions are consistent with the Figure 4 The projection direction itself is consistent.

[0052] like Figures 1 to 4As shown, this embodiment provides a silo 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 pivoting portion 122 and a first clamping portion 121 located below the pivoting 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 from left to right at intervals, so that the first clamping portion 121 and the second clamping portion 131 are arranged at intervals. The first clamping portion 121 is a side surface of the first clamping seat 12, and the second clamping portion 131 is a side surface 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 pivoting portion 122 of the first clamping seat 12 is rotatably mounted on the base 11 so that the first clamping portion 121 rotates 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 in a direction close to or away from the second clamping portion 131, so that the size of the feeding channel 14 can be changed. When the first clamping portion 121 rotates in a direction close to 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 in a direction away from the second clamping portion 131 so that the width of the lower end of the feeding channel 14 is greater than the width of the plate, the plate can leave the feeding channel 14 from the lower end of the feeding channel 14 to achieve feeding. When in use, the first clamping seat 12 is driven to rotate around the pivot portion 122 to rotate the first clamping portion 121 in a direction close to the second clamping portion 131, so that the width of the lower end of the feeding channel 14 is smaller than the width of the plate, and the stacked plates are stored in the feeding channel 14. When it is necessary to convey a plate, the first clamping seat 12 is driven to rotate around the pivot portion 122 so that the first clamping portion 121 rotates in a direction away from the second clamping portion 131. When the width of the lower end of the feeding channel 14 is greater than the width of the plate, the lowest plate is separated from the feeding channel 14 from the lower end of the feeding channel 14. When the lowest plate is separated from the feeding channel 14 from the lower end of the feeding channel 14, the first clamping portion 121 immediately rotates in a direction close to the second clamping portion 131 so that the width of the lower end of the feeding channel 14 is less than the width of the plate. The first clamping portion 121 and the second clamping portion 131 jointly clamp the lowest plate in the feeding channel 14 at this time. When it is necessary to convey the next plate, the first clamping seat 12 is continued to be driven to rotate around the pivot portion 122 so that the first clamping portion 121 rotates in a direction away from the second clamping portion 131. By continuously repeating the above steps, the first clamping portion 121 alternately moves away from and approaches the second clamping portion 131, thereby realizing the conveying of the plates one by one.Compared with the traditional method of clamping by robot, the silo mechanism of this embodiment can realize the one-by-one transportation of plates without the need for a robot to cooperate. The working process and structure of the silo mechanism are simpler. At the same time, compared with the traditional feeding equipment that needs to wait for the robot to complete the processes of grabbing, feeding, unloading, resetting, etc., the feeding efficiency of this application is higher. After the previous plate is sent out, the next plate can be carried out immediately.

[0054] Combination Figure 1 and Figure 2 When the length of the plate to be conveyed is relatively long, that is, the length of the plate along the rotation axis direction of the pivot portion 122 is relatively long, two silo mechanisms can be set up to cooperate to realize the conveying of the plate. The two silo mechanisms are distributed in a mirror-symmetrical manner, and the two silo mechanisms are arranged at intervals. The feeding channels 14 of the two silo mechanisms are relatively arranged and are both located in the area between the two silo mechanisms. The two ends of the plate in the length direction are clamped respectively by the feeding channels 14 of the two silo mechanisms, and the feeding of the plate is realized by driving the first clamping seats 12 of the two silo 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 and facilitate the plate to be placed in 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 member 18 and the first driver 15.

[0057] In one embodiment, the silo mechanism further includes a first driver 15 installed on the base 11. The first driver 15 is connected to the first clamping seat 12 in a transmission connection so that the first clamping portion 121 rotates in a direction close to or away from the second clamping portion 131. The first driver 15 can be connected to the first clamping seat 12 by a motor and a pivoting portion 122 to achieve the rotation of the first clamping seat 12, or it can be driven by a linear drive device such as a hydraulic cylinder, a cylinder, a pneumatic telescopic rod, a screw module, etc. to promote the rotation of the first clamping seat 12. In this embodiment, the first driver 15 uses a cylinder, which has the advantages of stable power output, higher reliability, low operating cost, and easy control. The cylinder is installed on the base 11 through the cylinder seat 21, and the output shaft of the cylinder is connected to the first clamping seat 12.

[0058] Combination Figures 4 to 7 Optionally, the silo mechanism further includes an elastic member 18. The elastic member 18 is a spring, and the first clamping seat 12 is connected to the base 11 through the elastic member 18. One end of the elastic member 18 is connected to the first clamping seat 12, and the other end of the elastic member 18 is connected to the base 11. The elastic member 18 is used to apply elastic force to make the first clamping seat 12 rotate in a direction away from the second clamping seat 13 and abut against the base 11. The elastic member 18 itself is in a stretched state, so that the first clamping portion 121 has a tendency to rotate in a direction away from the second clamping portion 131. When the first clamping portion 121 rotates in a direction close to the second clamping portion 131, the elastic member 18 is further stretched. The spring applies a force to the first clamping seat 12 to retract in the direction of the mounting plate 114 of the base 11. The first clamping seat 12 always has a tendency to be close to the mounting plate 114 of the base 11, so that the first clamping seat 12 remains in an open state to release the plate, thereby ensuring the feeding process. This can prevent the first clamping seat 12 from being unable to rebound to the open state to release the plate when the first driver 15 does not apply a force, thereby preventing materials such as the plate from being locked in the feeding channel 14.

[0059] Furthermore, a first hooking seat 29 is provided on the mounting plate 114 of the base 11, a second hooking seat 30 is provided on the first clamping seat 12, and a second mounting hole 119 is provided on the mounting plate 114 of the base 11. One end of the elastic member 18 is connected to the first hooking seat 29, and the other end of the elastic member 18 passes through the second mounting hole 119 and is connected to the first hooking seat 29, so as to facilitate 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. When the first clamping seat 12 of this embodiment moves in a direction away from the second clamping seat 13 and approaches the mounting plate 114, there are the following two positioning methods for the first clamping seat 12 and the mounting plate 114.

[0061] The first positioning method is: 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] This embodiment takes the first positioning method as an example, a first positioning block 117 is provided on the mounting plate 114 of the base 11, and a first positioning groove 123 is provided on the first clamping seat 12. When the first clamping seat 12 moves in a direction away from the second clamping seat 13 and approaches the mounting plate 114, the first clamping seat 12 is sleeved on the first positioning block 117 through the first positioning groove 123, so that the first clamping seat 12 and the mounting plate 114 are coordinated and positioned. When the hopper mechanism conveys and releases the plate, the first clamping seat 12 is coordinated and positioned with the mounting plate 114 to prevent the first clamping seat 12 from moving along the rotation axis direction of the pivot 122.

[0064] Optionally, in order 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, and the first mounting hole 118 penetrates the mounting plate 114 of the base 11 in a horizontal direction. When installing the second positioning block, a part of the second positioning block is installed on the outer side of the mounting plate 114 facing outward, which facilitates the installation of the second positioning block. The rest of the second positioning block passes through the first mounting hole 118 and extends 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 a flexible block such as a silicone block, which can avoid a rigid collision between the first clamping seat 12 and the mounting plate 114.

[0066] Combination Figure 1 and Figure 2In one embodiment, the second clamping seat 13 is slidably mounted on the base 11 so that the second clamping portion 131 moves in a direction close to or away from the first clamping portion 121. The second clamping seat 13 moves in a horizontal direction to approach or away from the first clamping seat 12. Specifically, a guide rod 19 and a first screw rod 20 are mounted on the base 11. The two ends of the first screw rod 20 are rotatably mounted on the first shaft plate 115 and the second shaft plate 116, respectively, and the second clamping seat 13 slides in a horizontal direction 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 stability of the sliding of the second clamping seat 13, there are two guide rods 19 in this embodiment, and the two are arranged from top to bottom at intervals, and the first screw rod 20 is located between the two guide rods 19. The first screw rod 20 and the two guide rods 19 are parallel to each other. A nut block 25 is installed on the first screw rod 20, a linear bearing 26 is installed on the guide rod 19, a bearing seat is installed on the linear bearing 26, the bearing seat is connected to the nut block 25 through a connecting plate 27, and the second clamping seat 13 is installed on the connecting plate 27. The second clamping seat 13 and the connecting plate 27 are arranged in sequence along the radial direction of the first screw rod 20. When the first screw rod 20 is driven to rotate by a power device such as manual or motor, the nut block 25 moves along the axial direction of the first screw rod 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 in a direction away from or close to the first clamping seat 12, the width of the feeding channel 14 can be changed, so that the feeding channel 14 can adapt to plates of different widths. Before feeding, according to the width of the plate, the second clamping seat 13 is driven to move in a direction away from or close to the first clamping seat 12, so that the first clamping seat 12 and the second clamping seat 13 clamp the plate together, and 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 silo mechanism further includes a second driver 16 mounted on the base 11. The second driver 16 is transmission-connected to the second clamping seat 13. The second driver 16 can be a power device such as a motor, or a hand wheel rotatably mounted on the base 11 and transmission-connected to the first screw rod 20.

[0068] Optionally, the silo mechanism further 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 plate falling from the feeding channel 14.

[0069] Furthermore, the bracket 24 includes a slide plate 241 and a support plate 242 mounted on the slide plate 241. The support plate 242 is used to catch the plate dropped from the feeding channel 14. The slide plate 241 is mounted on the base 11 in a sliding manner up and down to get close to or away from the feeding channel 14. By driving the slide plate 241 to slide up and down, the support plate 242 is moved close to or away from the lower end of the feeding channel 14, thereby adjusting the distance at which the support plate 242 catches the plate, thereby adjusting the distance at which the plate falls, and avoiding damage to the plate due to excessive height difference when the plate falls. At the same time, the position of the support plate 242 can be adjusted up and down according to the thickness of the plate, so that the distance between the support plate 242 and the lower end of the first clamping seat 12 and the distance between the support plate 242 and the lower end of the second clamping seat 13 are slightly greater than the thickness of one plate, thereby avoiding multiple plates from falling on the support plate 242 at the same time, and realizing one-by-one transportation.

[0070] It is understandable that after the support plate 242 receives the plate, the plate can be sent out by arranging a pushing device next to the support plate 242. Exemplarily, the pushing device includes a belt pulley that can move cyclically, and a plurality of push rods are arranged at intervals along the moving direction of the belt pulley, and each plate is pushed out in sequence by each push rod.

[0071] Optionally, the silo mechanism further includes a third driver 17, which is a device such as a cylinder. The third driver 17 is transmission-connected to the slide plate 241 to drive the slide plate 241 to slide up and down.

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

[0073] Optionally, the support plate 242 is rotatably mounted on the slide plate 241, and the support plate 242 has a material receiving surface. The support plate 242 switches between the unfolded position and the storage position. When the support plate 242 is in the unfolded position, the material receiving surface is set upward and horizontally set below the feeding channel 14. When the support plate 242 is in the storage position, the material receiving surface abuts against the base 11. Specifically, the support plate 242 is rotatably mounted on the upper end of the slide plate 241, and the rotation axis of the support plate 242 is set horizontally. The support plate 242 rotates up and down relative to the base 11. When it is not necessary to receive the plate, the support plate 242 flips upward so that the material receiving surface of the support plate 242 is close to the support plate 113 of the base 11 and fits with the support plate 113. The support plate 242 is in a vertically arranged state to save space. When it is necessary to receive the plate, the support plate 242 flips downward, and the material receiving surface is set upward and horizontally set below the feeding channel 14. When the support plate 242 switches between the unfolded position and the stored position, the slide plate 241 slides up and down to prevent the support plate 242 from interfering with the first clamping seat 12 and the second clamping seat 13 .

[0074] Combination Figure 2 and Figure 3 In one embodiment, the silo mechanism further includes a counting assembly 28, which can be used to conveniently adjust the height of the bracket 24. Specifically, the counting assembly 28 includes a position display 281, a second screw rod 282, an adjusting screw 283, an adjusting block 284, and a guide block 285. The position display 281 is also called a counter, which can be used to record the stroke of the second screw rod 282, so as to facilitate the height adjustment of the adjusting block 284, thereby facilitating the adjustment of the rising height of the bracket 24. There are two guide blocks 285 and they are arranged on the support plate 113 at intervals along the horizontal direction. The second screw rod 282 is rotatably installed between the two guide blocks 285, and the axis of the second screw rod 282 is vertically arranged. The adjusting block 284 is slidably arranged between the two guide blocks 285, and the adjusting block 284 is threadedly connected to the second screw rod 282 so that the adjusting block 284 can slide up and down along the second screw rod 282. The position display 281 is installed on the adjusting block 284. The adjusting screw 283 is installed on the support plate 113 and is threadedly connected to the adjusting block 284. By rotating the adjusting screw 283, the adjusting block 284 can be driven to drive the position display 281 to move up and down and abut against the bracket 24, so that the position display 281 can obtain the height position of the bracket 24 according to the position of the second screw rod 2821 at this time, thereby facilitating the adjustment of the maximum rising height of the bracket 24.
