[0002] With the advancement of technology, more and more factories use automated equipment to manufacture products. Especially in the production of 3C products, automated equipment has become popular.

[0003] In the process of preparing products by automated equipment, the loading and unloading structure of materials is an important link that affects the rhythm of the production line. For example, when loading materials through a pallet, there may be a lack of materials in the pallet, which will reduce the processing efficiency of the automated production line and even cause subsequent equipment to malfunction.

[0004] In the prior art, when loading materials onto a pallet, the materials in the pallet are manually checked to see if they are complete. If materials in the pallet are missing, the missing materials are manually replenished. However, manual operation has a certain probability of making mistakes, which also affects the processing efficiency of the automated production line.

[0161] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0162] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0163] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0164] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0165] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0166] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings.

In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0168] Figure 1 It is a schematic structural diagram of a feeding system according to one embodiment of the present disclosure. Figure 2 It is a schematic diagram of the internal structure of a feeding system according to one embodiment of the present disclosure.

[0169] like Figure 1 and Figure 2As shown, when the replenishing system of the present disclosure is in use, it is possible to replenish the missing materials in the tray and make the tray full.

[0170] Specifically, the feeding system of the present disclosure may include a frame structure, which may include a lower frame structure and an upper frame structure arranged on the lower frame structure, and the following structures such as the conveying device 300, the camera device 200, the handling device 700 and the feeding device 800 are all arranged on the frame structure and located inside the frame structure. The frame structure of the present disclosure includes a length direction and a width direction, wherein the length direction can be defined as a first direction, and the width direction can be defined as a second direction.

[0171] like Figure 1 and Figure 2 As shown, the feeding system of the present disclosure may further include components such as a camera device 200 , a conveying device 300 , a transport device 700 , and a feeding device 800 .

[0172] The conveying device 300 of the present disclosure is used to convey a pallet, wherein the pallet is loaded with materials; specifically, the materials loaded in the pallet are the same materials. In a specific embodiment, the feeding system can be set in an automated production line, in which case the conveying device 300 can be connected to the automated production line to receive the pallet conveyed by the automated production line, and when the materials in the pallet are replenished, the conveying device 300 can convey the pallet to the automated production line, and the pallet will continue to flow on the automated production line.

[0173] Figure 3 It is a schematic structural diagram of a conveying device according to one embodiment of the present disclosure. Figure 4 It is a schematic structural diagram of a conveying device according to an embodiment of the present disclosure from another angle. Figure 5 It is a structural schematic diagram of a partial structure of a conveying device according to one embodiment of the present disclosure. Figure 6 It is a structural schematic diagram of a partial structure of a conveying device according to an embodiment of the present disclosure from another angle.

[0174] like Figures 3 to 6 As shown, the conveying device 300 of the present disclosure includes components such as a conveying bottom plate 310 , a first supporting side plate 320 , a second supporting side plate 330 , a first conveying assembly 340 , a second conveying assembly 350 , and a first driving assembly 360 .

[0175] The conveying bottom plate 310 of the present disclosure is generally formed in a square shape, and its length direction is the second direction mentioned above, and its width direction is the first direction mentioned above. That is, the conveying device 300 of the present disclosure can convey the pallet along the second direction. In a specific embodiment, the conveying bottom plate 310 of the present disclosure is fixed to the frame structure.

[0176] The first supporting side plate 320 and the second supporting side plate 330 can be slidably disposed on the conveying bottom plate 310. Specifically, two guide rails are disposed on the conveying bottom plate 310, and the two guide rails are disposed in parallel and are both disposed along the first direction.

[0177] One end of the first supporting side plate 320 is slidably disposed on one of the two guide rails through a slider, and the other end thereof is slidably disposed on the other of the two guide rails through a slider. Similarly, one end of the second supporting side plate 330 is slidably disposed on one of the two guide rails through a slider, and the other end thereof is slidably disposed on the other of the two guide rails through a slider, thereby both the first supporting side plate 320 and the second supporting side plate 330 can slide on the guide rails, so that the first supporting side plate 320 and the second supporting side plate 330 can approach or move away from each other in the first direction.

[0178] Through the above structure, the length direction of the first supporting side plate 320 and the second supporting side plate 330 of the present disclosure is parallel to the second direction.

[0179] In the present disclosure, when the first supporting side plate 320 and the second supporting side plate 330 are approaching or moving away from each other, one of the first supporting side plate 320 and the second supporting side plate 330 can remain stationary. In a preferred embodiment, the first supporting side plate 320 and the second supporting side plate 330 can move in opposite directions at the same time, so that the first supporting side plate 320 and the second supporting side plate 330 can approach or move away from each other.

[0180] The first conveying assembly 340 is disposed on the first supporting side plate 320 and is located on the inner side of the first supporting side plate 320; similarly, the second conveying assembly 350 is disposed on the second supporting side plate 330 and is located on the inner side of the second supporting side plate 330. That is, the first conveying assembly 340 and the second conveying assembly 350 of the present disclosure are located in the area between the first supporting side plate 320 and the second supporting side plate 330, thereby, the pallet can be conveyed by the first conveying assembly 340 and the second conveying assembly 350. That is, at this time, a pallet loaded with materials can be placed on the first conveying assembly 340 and the second conveying assembly 350, and conveyed by the first conveying assembly 340 and the second conveying assembly 350.

[0181] The first driving assembly 360 is used to drive the first supporting side plate 320 and / or the second supporting side plate 330 to move so that the first supporting side plate 320 and the second supporting side plate 330 can approach each other or move away from each other, thereby, the conveying device of the present disclosure can adapt to pallets of different sizes; that is, the width between the first supporting side plate 320 and the second supporting side plate 330 of the present disclosure can change with the size of the pallet, so that the conveying device 300 of the present disclosure can convey pallets of different sizes, thereby achieving compatibility with pallets of different sizes.

[0182] The first driving assembly 360 of the present disclosure can simultaneously drive the first supporting side plate 320 and the second supporting side plate 330 , and make the first supporting side plate 320 and the second supporting side plate 330 have opposite movement directions.

[0183] Specifically, the first drive assembly 360 of the present disclosure may include a first drive motor and a first bidirectional screw 361 driven to rotate by the first drive motor, and the first bidirectional screw 361 may be a positive and negative trapezoidal screw. Specifically, the first drive motor is fixed to the conveying base plate 310; both ends of the first bidirectional screw 361 are rotatably arranged on the conveying base plate 310 through a bearing seat, and the axis of the first bidirectional screw 361 is arranged along the first direction, at this time, the bearing seat can limit the axial position of the first bidirectional screw 361.

[0184] A first nut is provided on the first supporting side plate 320, and a second nut is provided on the second supporting side plate 330. The first nut and the second nut have different spiral directions, and the first nut and the second nut are both matched with the first bidirectional spiral screw 361; thus, when the first bidirectional spiral screw 361 rotates in one direction, the first supporting side plate 320 and the second supporting side plate 330 can approach each other, and when the first bidirectional spiral screw 361 rotates in another direction, the first supporting side plate 320 and the second supporting side plate 330 can move away from each other.

[0185] The first conveying assembly 340 and the second conveying assembly 350 are both synchronous belt conveying assemblies, whereby the conveying of the pallet arranged on the synchronous belt can be realized through the movement of the synchronous belt of the synchronous belt conveying assembly. In the present disclosure, the first conveying assembly 340 includes a first driving wheel and at least one first driven wheel, and the first driving wheel and the first driven wheel are connected by a first synchronous belt transmission; similarly, the second conveying assembly 350 includes a second driving wheel and at least one second driven wheel, and the second driving wheel and the second driven wheel are connected by a second synchronous belt transmission.

[0186] The conveying device 300 of the present disclosure also includes a second drive component 370, which is used to drive the first conveying component 340 and the second conveying component 350 to move; that is, the second drive component 370 of the present disclosure is set as one, and the synchronous driving of the first conveying component 340 and the second conveying component 350 is achieved through one second drive component 370.

[0187] The second driving assembly 370 includes a second driving motor and a conveying driving shaft 371 driven by the second driving motor. The cross section of the conveying driving shaft 371 is non-circular, for example, hexagonal. The first driving wheel and the second driving wheel are both slidably disposed on the conveying driving shaft 371 and driven by the conveying driving shaft 371 to rotate.

[0188] Specifically, both ends of the conveying drive shaft 371 of the present invention are rotatably supported on the conveying base plate 310 through bearing seats, and the axial position of the conveying drive shaft 371 can be limited by the bearing seats, that is, the axis of the conveying drive shaft 371 is set along the first direction and will not move along the first direction.

[0189] The first driving wheel is rotatably supported on the first supporting side plate 320 through a bearing, and the conveying drive shaft 371 can slide in the inner hole of the bearing, so that the conveying drive shaft 371 does not affect the movement of the first supporting side plate 320 in the first direction. Similarly, the second driving wheel is rotatably supported on the second supporting side plate 330 through a bearing, and the conveying drive shaft 371 can slide in the inner hole of the bearing, so that the conveying drive shaft 371 does not affect the movement of the second supporting side plate 330 in the first direction.

[0190] The conveying device 300 of the present disclosure further includes a conveying lifting assembly 380 , which drives the pad 390 between the first supporting side plate 320 and the second supporting side plate 330 to rise or fall, thereby causing the pallet carried on the pad 390 to rise or fall.

[0191] Specifically, the upper surface of the first synchronous belt of the present invention can be formed into a discontinuous structure by a reversing wheel. Similarly, the upper surface of the second synchronous belt can also be formed into a discontinuous structure. Thus, at least a portion of the pad 390 can move through the gap on the upper surface of the first synchronous belt and the gap on the upper surface of the second synchronous belt to below the upper surface of the first synchronous belt and the upper surface of the second synchronous belt. At this position, the pad 390 will not affect the movement of the pallet on the conveying device 300.

[0192] The conveying device 300 disclosed herein may further include a blocking device, which may include a lifting cylinder and a blocking plate driven by the lifting cylinder. When the lifting cylinder is in an ascending position, the blocking plate can block the pallet conveyed by the first conveying assembly 340 and the second conveying assembly 350. When the lifting cylinder is in a descending position, the blocking plate will not block the movement of the pallet.

[0193] Thus, the pallet can be blocked by the blocking device and is located directly above the pad 390. Next, when the pad 390 rises, it can cause the pallet to rise, and the raised pallet can be conveniently carried by the carrying device 700 described below.

[0194] In one embodiment, not all pallets are transported by the transport device, and most of the pallets will stay at the conveying device 300 and be replenished with materials.

[0207] like Fig.10 As shown, the first driving device 740 of the present invention is a screw-nut structure driven by a motor, and the first driving device 740 is located below the first support beam 712, and the nut of the first driving device 740 passes through the first support beam 712 and is fixed to the cross beam 730; that is, at least a portion of the nut of the first driving device 740 of the present invention is located in the through hole of the first support beam 712 and can slide in the through hole, thereby, the cross beam 730 of the present invention can move stably without being stuck.

[0208] Since the motor-driven screw-nut structure is a common structure in the art, the present disclosure will not describe this structure in detail.

[0209] Refer to Figure 8 and Fig. 9 The second support assembly 720 of the present disclosure includes components such as a second support column 721, a second support beam 722, a third guide rail 723 and a third slider 724.

[0213] Fig.11 It is a schematic structural diagram of a material-retrieving plate of a handling device according to an embodiment of the present disclosure. Fig.12 It is a schematic structural diagram of a material-retrieving plate of a transport device according to an embodiment of the present disclosure from another angle.

Thus, the transport suction cup 780 of the present disclosure can be installed in different long strip holes, or installed in different positions of a long strip hole, so that the position of the transport suction cup 780 is adjustable, and accordingly, the transport device 700 of the present disclosure can be applied to pallets of different shapes and sizes.

[0217] Fig.13 It is a schematic structural diagram of a redundant carrying device of a handling device according to an embodiment of the present disclosure.

[0218] The handling device 700 of the present disclosure further includes a redundant carrying device 790, which is used to carry a pallet. Specifically, the handling device 700 is used to carry the pallet conveyed by the conveying device 300 to the redundant carrying device 790. For example, the handling suction cup 780 of the handling device 700 can suck the pallet on the conveying device 300 and carry the pallet to the redundant carrying device 790.

[0219] That is to say, when the replenishing system of the present invention is in use, the transport device 700 first transports a pallet loaded with materials at the conveying device 300 to the redundant carrying device 790; then, the other pallet loaded with materials at the conveying device 300 is transported to the buffer device 400; thus, the replenishing system of the present invention includes two pallets for replenishing materials, and accordingly, when the pallet at the conveying device 300 needs to be replenished, materials can be taken out from one pallet and replenished; when all the materials in the pallet are used for replenishing, the empty pallet will be unloaded; and then materials are taken out from another pallet and replenished.

[0220] When the material replenishment is completed, the transport device 700 can transport the next pallet transported by the conveying device 300 to the buffer device 400 or the redundant load-bearing device 790 , so that there are always pallets loaded with materials on the buffer device 400 and the redundant load-bearing device 790 .

[0221] In a specific embodiment, the redundant bearing device 790 includes: a first vertical plate 791, a second vertical plate 792, a second driving device 793, a second bearing platform 794 and other structures.

Moreover, the length direction of the first vertical plate 791 and the length direction of the second vertical plate 792 are both parallel to the length direction of the first support assembly 710 .

[0224] The second driving device 793 is disposed on the first vertical plate 791; in a specific embodiment, the second driving device 793 is also a screw nut structure driven by a motor, and the second driving device 793 is located on the side of the first vertical plate 791. One end of the second bearing platform 794 is fixed to the second driving device 793, that is, one end of the second bearing platform 794 can be fixed to the nut of the second driving device 793, and the other end of the second bearing platform 794 is slidably disposed on the second vertical plate 792.

[0225] In addition, a fourth guide rail 795 is provided on the second vertical plate 792, and a fourth slider 796 is fixed to the other end of the second supporting platform 794. The fourth slider 796 is slidably provided on the fourth guide rail 795, thereby, the second supporting platform 794 of the present disclosure can move along the length direction of the first supporting assembly 710.

[0226] Therefore, the second carrying platform 794 of the present disclosure can be used to carry the tray, and the second carrying platform 794 can move so that the second carrying platform 794 and the cache device 400 can be in different positions.

[0227] Fig.14 It is a schematic diagram of the structure of a cache device according to an embodiment of the present disclosure.

[0228] like Fig.14 As shown, the cache device 400 of the present disclosure includes a driving module 410 and a first supporting platform 420 disposed on the driving module 410. The driving module 410 is directly or indirectly disposed on the frame structure and is used to drive the first supporting platform 420 to rise or fall. In a specific embodiment, the driving module 410 of the present disclosure can be a structure such as a cylinder or a screw motor.

[0229] Therefore, the cache device 400 of the present invention can make the pallet supported on the first supporting platform 420 descend, so that the second supporting platform can move to the top of the first supporting platform, so that the second supporting platform no longer covers the upper end of the silo device 100, and the empty pallet can be placed in the silo and the unloading of the empty pallet can be realized.

[0230] Fig.15 It is a schematic structural diagram of a feeding device 800 according to an embodiment of the present disclosure.

[0231] The replenishing device 800 of the present disclosure is used to replenish the materials in the tray at the buffer device 400 to the tray at the conveying device 300. Moreover, the replenishing device 800 is also used to replenish the materials in the tray carried by the redundant carrying device to the tray at the conveying device 300.

[0232] The feeding device 800 of the present disclosure may include components such as a motion platform 810 , a pitch changing device 820 , and a feeding module 830 .

[0233] The motion platform 810 is disposed on the crossbeam 730 and is configured to be able to move along a second direction; wherein the second direction may be a horizontal direction, in which case the crossbeam 730 is also disposed along the second direction. In a specific embodiment, the motion platform 810 is a motor-driven screw-nut structure. Since the motor-driven screw-nut structure is a common structure in the art, the present disclosure will not further describe its structure one by one.

[0234] The variable pitch device 820 is arranged on the moving platform 810, and the moving platform 810 drives the variable pitch device 820 to reciprocate along the second direction; therefore, when the feeding device 800 of the present disclosure is in use, it can not only change the distance between materials, but also make the materials as a whole move along the second direction.

[0235] In a specific embodiment, the pitch changing device 820 is a cam pitch changing mechanism driven by a motor.

[0236] Fig.17 It is a schematic structural diagram of a motion platform and a pitch-changing device of a feeding device according to an embodiment of the present disclosure. Fig.18 It is a structural schematic diagram of the motion platform and the pitch changing device of the feeding device according to an embodiment of the present disclosure from another angle.

[0237] like Fig.17 and Fig.18As shown, the pitch changing device 820 of the present disclosure includes a housing 821, and a plurality of fifth guide rails 822 are arranged on the housing 821, wherein the plurality of fifth guide rails 822 are arranged along the second direction. Specifically, one surface of the housing 821 of the present disclosure is arranged substantially vertically, and a through hole is opened on the surface, and the through hole extends along the second direction. At the same time, the camshaft of the pitch changing device 820 also extends along the second direction, and the camshaft corresponds to the position of the through hole in the height direction.

[0238] The variable pitch device 820 of the present disclosure further includes a variable pitch block 823, wherein the variable pitch block 823 can be driven by the camshaft to change the distance in the second direction. That is, at least a portion of the variable pitch block 823 can be inserted into the interior of the housing 821 via the through hole, whereby the portion of the variable pitch block 823 located in the housing 821 can slide in the cam groove on the camshaft, so that the variable pitch block 823 can change its position in the second direction.

[0239] Refer to Fig.15 The feeding modules 830 of the present disclosure are arranged in plurality, wherein the distance changing device 820 is used to drive the plurality of feeding modules 830 to move so that the distance between adjacent feeding modules 830 can be changed.

[0240] That is to say, the variable distance blocks 823 of the present disclosure can be arranged in the same number as the material replenishment modules 830 and in one-to-one correspondence, so that when the variable distance blocks 823 move in the second direction, the material replenishment modules 830 can move in the second direction.

[0241] The feeding module 830 is provided with a slider 824; specifically, the feeding module 830 of the present disclosure is not directly connected to the slider 824, but is indirectly connected to the slider 824. For example, the feeding module 830 can be connected to the variable distance block 823 through the first connecting member 840, and the variable distance block 823 is connected to the slider 824, wherein each variable distance block 823 is provided with two sliders 824.

[0242] In the present disclosure, the sliders 824 of adjacent material replenishing modules 830 are respectively slidably disposed on different fifth guide rails 822. The slider 824 of the material replenishing module 830 refers to the slider 824 corresponding to the material replenishing module 830.

[0243] Specifically, the fifth guide rail 822 includes a first fifth guide rail, a second fifth guide rail, a third fifth guide rail and a fourth fifth guide rail; the first fifth guide rail, the second fifth guide rail, the third fifth guide rail and the fourth fifth guide rail are arranged in sequence from top to bottom and are distributed at equal intervals.

[0244] In the present disclosure, each feeding module 830 is provided with two sliders 824, that is, each feeding module 830 corresponds to two sliders, wherein, along the second direction, the feeding modules 830 located at odd positions (that is, along the Fig.15 The two sliders 824 (from left to right) are slidably arranged on the first and fifth guide rails and the third and fifth guide rails respectively; the feeding module 830 located at the even position (i.e., along the Fig.15 The two sliders 824 (from left to right direction) are slidably disposed on the second and fifth guide rails and the fourth and fifth guide rails respectively.

[0245] Therefore, the sliders 824 of two adjacent feeding modules 830 will not interfere with each other, and accordingly, the two feeding modules 830 can be closely approached. At this time, the feeding device 800 can be suitable for closely arranged materials.

[0246] Fig.19 It is a schematic structural diagram of a feeding module of a feeding device according to one embodiment of the present disclosure. Fig. 20 and Fig.21 It is a schematic structural diagram of other angles of a feeding module of a feeding device according to an embodiment of the present disclosure.

[0247] like Figures 19 to 21 As shown, in one embodiment, the first connecting member 840 corresponding to the feeding module 830 located at the even-numbered position is connected to the second connecting member 850 , and the second connecting member 850 is guided by the guide rod 860 .

[0248] Specifically, guide holes are provided on the second connecting member 850 of the present invention, and the guide rod 860 passes through these guide holes, allowing the second connecting member 850 to slide along the guide rod 860. Therefore, the feeding module 830 located at an even position of the present invention has higher precision during movement.

[0249] The second connecting member 850 of the present invention is formed into a roughly L-shaped structure, that is, it includes a horizontal segment and a vertical segment that are vertically connected, wherein the other end of the horizontal segment is connected to the upper end of the first connecting member 840, the feeding module 830 is fixed to the vertical segment, and the feeding module 830 is located in the space enclosed by the first connecting member and the second connecting member.

[0250] In a preferred embodiment, the feeding module 830 is fixedly connected to the second connecting member 850 , whereby the feeding module 830 of the present disclosure can maintain a firmly fixed relationship with the distance variable block 823 .

[0251] Refer to Figures 19 to 21The feeding module 830 of the present disclosure includes an output shaft 831, and the output shaft 831 can rotate and rise and fall relative to the first connecting member 840. In other words, the feeding module 830 of the present disclosure can be formed as a ZR module (or referred to as a ZR shaft), and the rotational degree of freedom and the lifting degree of freedom of the feeding module 830 can be independent degrees of freedom.

[0252] A mounting plate 832 is fixed on the output shaft 831 of the present invention, and a feeding suction cup 833 and a positioning column 834 are fixed on the lower surface of the mounting plate 832. Thus, the feeding device 800 of the present invention can suck materials through the feeding suction cup 833, and limit the distance between the material and the mounting plate 832 through the positioning column 834, thereby realizing the positioning of the material.

[0253] In one embodiment, the shell 821 of the pitch changing device 820 of the present disclosure is disposed on a connecting plate 870, and the connecting plate 870 is fixedly connected to a nut of the motion platform 810. The motion platform 810 can drive the pitch changing device 820 to move along a preset horizontal direction (second direction).

[0256] The silo bottom plate 110 of the present disclosure is generally formed in a square shape and is fixed to the frame structure; the first support plate 120 and the second support plate 130 are both slidably disposed on the silo bottom plate 110. Specifically, two guide rails are disposed on the silo bottom plate 110, and the two guide rails are disposed in parallel and are both disposed along the second direction.

[0257] One end of the first support plate 120 is slidably disposed on one of the two guide rails through a slider, and the other end thereof is slidably disposed on the other of the two guide rails through a slider. Similarly, one end of the second support plate 130 is slidably disposed on one of the two guide rails through a slider, and the other end thereof is slidably disposed on the other of the two guide rails through a slider, thereby both the first support plate 120 and the second support plate 130 can slide on the guide rails, so that the first support plate 120 and the second support plate 130 can approach or move away from each other in the second direction.

[0258] Through the above structure, the length directions of the first support plate 120 and the second support plate 130 of the present disclosure are parallel to the first direction.

[0259] In the present disclosure, when the first support plate 120 and the second support plate 130 are approaching or moving away from each other, one of the first support plate 120 and the second support plate 130 can remain stationary. In a preferred embodiment, the first support plate 120 and the second support plate 130 can move in opposite directions at the same time, so that the first support plate 120 and the second support plate 130 can approach or move away from each other.

[0260] The first silo conveying assembly 140 is disposed on the first support plate 120 and is located on the inner side of the first support plate 120; similarly, the second silo conveying assembly 150 is disposed on the second support plate 130 and is located on the inner side of the second support plate 130. That is, the first silo conveying assembly 140 and the second silo conveying assembly 150 of the present disclosure are located in the area between the first support plate 120 and the second support plate 130, thereby, the pallets (i.e., the empty pallets) can be conveyed by the first silo conveying assembly 140 and the second silo conveying assembly 150. That is, at this time, a stack of empty pallets (i.e., at least one stack of empty pallets) can be placed on the first silo conveying assembly 140 and the second silo conveying assembly 150, and conveyed outward by the first silo conveying assembly 140 and the second silo conveying assembly 150.

[0261] The first silo drive assembly 160 is used to drive the first support plate 120 and / or the second support plate 130 to move so that the first support plate 120 and the second support plate 130 can approach each other or move away from each other, thereby, the silo device of the present disclosure can adapt to pallets of different sizes; that is, the width between the first support plate 120 and the second support plate 130 of the present disclosure can change with the size of the pallet, so that the silo device 100 of the present disclosure can transport pallets of different sizes, thereby achieving compatibility with pallets of different sizes.

[0262] Specifically, the first silo driving assembly 160 of the present disclosure can drive the first support plate 120 and the second support plate 130 simultaneously, and make the first support plate 120 and the second support plate 130 have opposite movement directions.

[0263] Specifically, the first silo drive assembly 160 of the present disclosure may include a first drive motor and a second bidirectional screw 161 driven to rotate by the first drive motor, and the second bidirectional screw 161 may be a positive and negative thread trapezoidal screw. Specifically, the first drive motor is fixed to the silo bottom plate 110; the two ends of the second bidirectional screw 161 are rotatably arranged on the silo bottom plate 110 through a bearing seat, and the axis of the second bidirectional screw 161 is arranged along the second direction, at this time, the bearing seat can limit the axial position of the second bidirectional screw 161.

[0264] A first nut is provided on the first support plate 120, and a second nut is provided on the second support plate 130. The first nut and the second nut have different spiral directions, and the first nut and the second nut are both matched with the second bidirectional spiral screw; thus, when the second bidirectional spiral screw 161 rotates in one direction, the first support plate 120 and the second support plate 130 can approach each other, and when the second bidirectional spiral screw 161 rotates in another direction, the first support plate 120 and the second support plate 130 can move away from each other.

[0265] The first silo conveying assembly 140 and the second silo conveying assembly 150 are both synchronous belt conveying assemblies, whereby the conveying of the pallet arranged on the synchronous belt can be achieved through the movement of the synchronous belt of the synchronous belt conveying assembly. In the present disclosure, the first silo conveying assembly 140 includes a first driving wheel 141 and at least one first driven wheel, and the first driving wheel 141 and the first driven wheel are connected by a first synchronous belt transmission; similarly, the second silo conveying assembly 150 includes a second driving wheel 151 and at least one second driven wheel, and the second driving wheel 151 and the second driven wheel are connected by a second synchronous belt transmission. Since the synchronous belt conveying assembly is a common structure in the art, its structure will not be described in detail in the present disclosure.

[0266] The silo device 100 of the present disclosure also includes a second silo drive assembly 170, which is used to drive the first silo conveying assembly 140 and the second silo conveying assembly 150 to move; that is, the second silo drive assembly 170 of the present disclosure is set as one, and the synchronous driving of the first silo conveying assembly 140 and the second silo conveying assembly 150 is achieved through one second silo drive assembly 170.

[0267] The second silo drive assembly 170 includes a second drive motor and a drive shaft 171 driven by the second drive motor. The cross section of the drive shaft 171 is non-circular, for example, hexagonal. The first driving wheel 141 and the second driving wheel 151 are both slidably disposed on the drive shaft 171 and driven by the drive shaft 171 to rotate.

[0268] Specifically, both ends of the drive shaft 171 of the present invention are rotatably supported on the silo bottom plate 110 through bearing seats, and the axial position of the drive shaft 171 can be limited by the bearing seats, that is, the axis of the drive shaft 171 is set along the second direction and will not move along the second direction.

[0269] The first driving wheel 141 is rotatably supported on the first support plate 120 through a bearing, and the driving shaft 171 can slide in the inner hole of the bearing, so that the driving shaft 171 does not affect the movement of the first support plate 120 in the second direction. Similarly, the second driving wheel 151 is rotatably supported on the second support plate 130 through a bearing, and the driving shaft 171 can slide in the inner hole of the bearing, so that the driving shaft 171 does not affect the movement of the second support plate 130 in the second direction.
