Description

Technical Field

[0001] The invention relates to the technical field of material conveying in a stereoscopic warehouse, in particular to a material conveying mechanism used for wood processing. Background Art

[0002] In order to facilitate storage before using wood, it is often necessary to cut the wood into boards that are easy to store according to processing requirements and properly store them in a three-dimensional warehouse. During cutting, operators can conduct strict quality inspections on the boards, remove unqualified products, and ensure that each piece of board meets the standards. These carefully processed boards will be stacked in an orderly manner on the multi-layer shelves of the three-dimensional warehouse. When storing board-shaped wood, the three-dimensional warehouse not only greatly improves the storage efficiency of the board-shaped wood, but also provides a safe and stable storage environment for the wood boards through good ventilation, moisture-proof and fire-proof designs, ensuring that the wood boards remain in the best condition during long-term storage and are ready to meet production or sales needs at any time.

[0003] At present, when discharging wood from a stereoscopic warehouse, a tunnel stacking type discharging device is often used to transfer the wood. Although the above discharging device can complete the discharging of wood, it still has the following disadvantages in actual use:

[0037] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0038] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, a feeding mechanism for wood processing includes a movable support 2, which includes a movable top plate 201, a movable bottom plate 202 and two groups of support columns 203. The movable top plate 201 and the movable bottom plate 202 are slidably connected to the positioning tracks 101 provided at the upper and lower parts of the stereoscopic warehouse 1 respectively. The movable support 2 is driven by a driving structure to slide along the two groups of positioning tracks 101 in a limited manner. Two groups of support columns 203 are vertically and fixedly installed between the movable top plate 201 and the movable bottom plate 202. Lifting structures are installed on both groups of support columns 203. A group of feeding structures 3 are slidably installed on one group of support columns 203, and the feeding structures 3 are driven to lift by the corresponding connected lifting structures. Multiple groups of stock storage structures 4 are slidably installed on the other group of support columns 203, and the multiple groups of stock storage structures 4 are driven to lift by the corresponding connected lifting structures;

[0039] Specifically, in the present invention, the driving structure for driving the movable bracket 2 to move can be selected from the prior art. For example, an electric rail mobile vehicle or other components with the ability to drive and move along the track can be selected. The present invention does not have strict requirements for the selection of the driving structure. Similarly, the driving structure for driving the storage structure 4 and the lifting structure of the storage structure 4 can adopt the prior art. For example, in the prior art, a hanging rope structure can be selected to adjust the lifting or lowering of the feeding structure 3, and a rack and pinion structure can be selected for the independent lifting components of multiple groups of storage structures 4. The present invention will not elaborate too much on the driving structure and the lifting structure here;

[0040] Among them, as Figure 3 and Figure 4 shown, the feeding structure 3 includes a feeding bottom plate 301, a rotary base 302, a mounting plate 303, and two sets of single-depth forks 304. The feeding bottom plate 301 is connected to the lifting structure. The rotary base 302 is fixedly installed on the storage bottom plate 401, and a mounting plate 303 is fixedly installed on the upper end rotary end face thereof. The two sets of single-depth forks 304 are arranged in parallel and are slidably installed on the mounting plate 303 through mounting sliders 306. The two sets of single-depth forks 304 are driven to move mirror-symmetrically by a first adjusting component 305 on the mounting plate 303. A row of movable insertion plates 3041 are respectively rotatably installed on the near sides of the uppermost bearing plates of the two sets of single-depth forks 304, and the two rows of movable insertion plates 3041 can extend towards the middle of the two sets of single-depth forks 304;

[0041] Such as Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the material storage structure 4 includes a material storage bottom plate 401, a supporting connecting plate 402 and two groups of clamping plate groups 403. The material storage bottom plate 401 is connected to the lifting structure. The supporting connecting plate 402 is installed at the upper end of the material storage bottom plate 401, and includes a main supporting plate 4021 and two groups of side supporting plates 4022. The main supporting plate 4021 is elastically connected with a movable supporting plate 4023. The two groups of side supporting plates 4022 are rotatably installed on both sides of the main supporting plate 4021. The far ends of the two groups of side supporting plates 4022 are rotatably connected with the movable sliding block 4051 at the bottom of the material storage bottom plate 401, and the two groups of movable sliding blocks 4051 are controlled by the second adjusting mechanism at the bottom of the material storage bottom plate 401. Component 405 drives the mirror image movement to adjust the supporting state of the supporting connecting plate 402. The two groups of clamping plate groups 403 are respectively installed on both sides of the material storage bottom plate 401. The clamping plate group 403 includes a fixed vertical plate 4031, a telescopic clamping plate and a transmission component 404. The fixed vertical plate 4031 is fixedly installed on one side of the material storage bottom plate 401. The upper end of the telescopic clamping plate is slidably connected to the fixed vertical plate 4031 through a limiting column 4034. The telescopic clamping plate is transmission-connected to the movable support plate 4023 elastically installed on the main support plate 4021 through the transmission component 404. The movable support plate 4023 is pressed down to drive the two groups of telescopic clamping plates to approach each other in a mirror image.

[0042] like Figure 3 and Figure 4As shown, in the embodiment of the present invention, the first adjustment component 305 includes two groups of first double-threaded screw rods 3051 and two groups of first power motors 3052, the two groups of first double-threaded screw rods 3051 are rotatably installed on both sides of the mounting plate 303, and the two ends of the first double-threaded screw rods 3051 are mirror-imaged with transmission threads, and the two groups of first power motors 3052 are respectively connected to the ends of the corresponding first double-threaded screw rods 3051 for transmission, and the two groups of first power motors 3052 drive the two groups of first double-threaded screw rods 3051 to rotate synchronously, and the mounting sliders 306 on both sides of the single-depth fork 304 are respectively provided with internal threaded holes, and form a spiral pair transmission with the transmission threads on the two groups of first double-threaded screw rods 3051, wherein the single-depth fork 304 is a prior art and is not described in detail. In the present invention, when it is necessary to adjust the two When the spacing of the two sets of single-depth forks 304 is adjusted, the two sets of first power motors 3052 can be turned on to drive the two correspondingly connected sets of first double-threaded screw rods 3051 to rotate. Since the transmission threads on the first double-threaded screw rods 3051 are mirror-imaged, when the first double-threaded screw rods 3051 rotate, the two sets of mounting slide blocks 306 can move the transmission belts 4048 to drive the two sets of single-depth forks 304 to move in a mirror-image manner, so that the positions of the two sets of single-depth forks 304 can be adjusted accordingly according to the difference between the actual feeding of the whole pallet wood and the partial wood. When the feeding operation of the whole pallet is carried out, the spacing of the two sets of single-depth forks 304 can be adjusted to meet the insertion requirements of the pallet, and when the feeding of partial wood is carried out, the spacing of the two sets of single-depth forks 304 can be adjusted to meet the width requirements of the wood.

[0043] Furthermore, the movable plug plate 3041 is rotatably installed on one side of the pressure plate through a drive shaft 3042, and the drive shaft 3042 is driven to rotate by a drive motor installed on the side of the single-depth fork 304. The storage and extension of the movable plug plate 3041 can be flexibly adjusted according to actual conditions. Specifically, when it is necessary to feed part of the wood on the pallet, the corresponding movable plug plate 3041 can be driven to rotate by multiple sets of drive motors, and the pressure plate at the upper end of the single-depth fork 304 is extended to form a plug plate structure that can be inserted into the bottom of the fed wood. When feeding the pallet, the corresponding movable plug plate 3041 can be driven by multiple sets of drive motors to reset and rotate, and stored in the yield groove set on the pressure plate. In the present invention, the driving member used to drive the multiple sets of movable plug plates 3041 to rotate synchronously is selected as a multiple set of drive motors. Of course, in actual design, components that can be driven to rotate synchronously can also be selected, such as a chain drive structure, etc.

[0044] like Figure 7 and Figure 8As shown, in the embodiment of the present invention, the second adjustment assembly 405 includes a second double-threaded lead screw 4052 and a second power motor 4053. The second double-threaded lead screw 4052 is rotatably installed at the bottom of the storage base plate 401. Transmission threads are mirror-symmetrically arranged at both ends of the second double-threaded lead screw 4052. The second power motor 4053 is in transmission connection with the end of the second double-threaded lead screw 4052. The second double-threaded lead screw 4052 is driven to rotate by the second power motor 4053. The two groups of movable sliders 4051 are slidably installed in two groups of communicating chutes opened on the storage base plate 401, and respectively form a helical pair transmission with the two groups of transmission threads on the second double-threaded lead screw 4052. In the present invention, the shape of the support connecting plate 402 in the corresponding storage assembly can also be adjusted correspondingly according to the working conditions of the placement tray and some wood. When the support connecting plate 402 is used for placing the tray, at this time, the second power motor 4053 in the second adjustment assembly 405 can be rotated, and the two groups of movable sliders 4051 are driven by the threaded transmission belt 404 to move mirror-symmetrically towards both ends, and the support connecting plate 402 is pulled flat and placed on the storage base plate 401. And when the support connecting plate 402 is used for placing some wood, at this time, the second power motor 4053 in the second adjustment assembly 405 can be rotated in the reverse direction, and the two groups of movable sliders 4051 are driven by the threaded transmission belt 404 to move mirror-symmetrically towards the middle. And while the two groups of side support plates 4022 move closer, the main support plate 4021 is lifted to form a trapezoidal structure for placing wood. Spaces are left on both sides of the main support plate 4021 for the single-depth fork 304 to move. The single-depth fork 304 can stably place the wood on the main support plate 4021. And the height of the upward movement of the main support plate 4021 is consistent with the height of the tray, so as to facilitate the clamping plate group 403 in the subsequent storage structure 4 to clamp and fix the wood, and improve the stability of the wood when the movable bracket 2 moves;

[0045] Of course, in actual design, the first adjustment assembly 305 for adjusting the distance between the two groups of single-depth forks 304 and the second adjustment assembly 405 for driving the two groups of movable sliders 4051 can also select other components with mirror-driving capabilities, such as a gear and double-rack structure. The present invention does not make strict requirements on the first adjustment assembly 305 and the second adjustment assembly 405.

[0046] Such as Figure 6 and Figure 8As shown, in the embodiment of the present invention, a plurality of groups of guide columns 4024 are fixedly installed at the bottom of the movable support plate 4023, and the plurality of groups of guide columns 4024 are slidably installed in the guide holes opened on the main support plate 4021, and extend out from the connecting grooves opened on the material storage bottom plate 401. The guide columns 4024 are located on the column bodies on the lower side of the main support plate 4021 and are wound with support springs 4025. The upper ends of the support springs 4025 are elastically connected to the bottom end faces of the main support plates 4021. In the present invention, the movable support plate 4023 is elastically arranged on the main support plate 4021. When wood is placed on the supporting connecting plate 402, the wood can press the movable support plate 4023 downward, and drive the clamping plate groups 403 on both sides of the material storage bottom plate 401 to clamp the wood on both sides through the transmission assembly 404, thereby ensuring that the wood remains in a stable state when the material storage structure 4 moves vertically or the movable bracket 2 moves horizontally.

[0047] like Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the transmission assembly 404 includes a main transmission shaft 4043, a secondary transmission shaft 4045, a telescopic shaft 4044 and a driving screw 4047. The main transmission shaft 4043 is rotatably mounted on the bottom of the main support plate 4021, and is transmission-connected to the guide column 4024 at the bottom of the movable support plate 4023 through a gear assembly. The secondary transmission shaft 4045 is rotatably mounted on the fixed vertical plate 4031, and is transmission-connected to the main transmission shaft 4043 through the telescopic shaft 4044. The driving screw 4047 is fixedly mounted on the upper end of the telescopic clamping plate, and is rotatably mounted on the fixed vertical plate 4031 to form a spiral secondary transmission with the rotating nut 4046, and the secondary transmission shaft 4045 is transmission-connected to the rotating nut 4046 through a transmission belt 4048.

[0048] Further, the gear assembly includes a transmission gear 4041 and a fixed rack 4042, the transmission gear 4041 is coaxially mounted on the main transmission shaft 4043, and the fixed rack 4042 is fixedly mounted on the corresponding guide column 4024 and meshedly connected with the transmission gear 4041;

[0049] Furthermore, a set of transmission bevel gears 4049 are fixedly installed at both ends of the telescopic rotating shaft 4044, and the two sets of rotating bevel gears are respectively meshed with the transmission bevel gears 4049 at the ends of the main transmission shaft 4043 and the auxiliary transmission shaft 4045 for transmission;

[0050] In the present invention, when the stock storage structure 4 is used to clamp the wood on the pallet, the support connecting plate 402 is in a horizontal state at this time. When the pallet is moved and placed on the support connecting plate 402 by the two groups of single-depth forks 304, the movable support plate 4023 on the main support plate 4021 in the middle of the support connecting plate 402 is pressed down by the pallet. While the support spring 4025 at the bottom of the pallet extends, the fixed rack 4042 on the guide post 4024 is in transmission engagement with the transmission gear 4041 to drive the main transmission shaft 4043 to rotate, and the telescopic rotating shaft 4044 drives the secondary transmission shaft 4045 and the rotary nut 4046 in transmission connection with the secondary transmission shaft 4045 to rotate. Finally, the threaded transmission belt 4048 drives the driving screw 4047 and the telescopic clamping plate to move, and the telescopic clamping plate is pressed against one side of the wood;

[0051] And when clamping some of the fed wood, at this time the support connecting plate 402 is adjusted by the second adjustment assembly 405 to form a trapezoidal placement table. At this time, as the main support plate 4021 rises, the main transmission shaft 4043 installed at its bottom rises synchronously, and the corresponding telescopic rotating shaft 4044 shortens synchronously. When the wood is transferred and placed on the support connecting plate 402 by the movable insertion plates 3041 of the two groups of single-depth forks 304, the movable support plate 4023 is pressed down by the wood. Through the transmission of the gear assembly, the main transmission shaft 4043, the telescopic rotating shaft 4044, the secondary transmission shaft 4045 and the rotary nut 4046, finally the telescopic clamping plate is pressed against one side of the wood. Since the height of the upward movement of the main support plate 4021 in the present invention is consistent with the height of the pallet, the two groups of telescopic clamping plates can stably clamp the wood for operation.

[0052] As Figure 5 and Figure 6 shown, in the embodiment of the present invention, the telescopic clamping plate includes a fixed clamping plate 4032 and a movable clamping plate 4033. There are meshing teeth inserted crosswise between the fixed clamping plate 4032 and the movable clamping plate 4033. A plurality of limiting posts 4034 are fixedly installed on one side end face of the fixed clamping plate 4032 close to the fixed vertical plate 4031 and are slidably connected corresponding to a plurality of limiting holes opened on the fixed vertical plate 4031. The movable clamping plate 4033 is slidably connected to the bottom of the fixed clamping plate 4032, and a set of fixed rods 4035 are respectively installed on both sides thereof. The two sets of fixed rods 4035 are slidably connected to the guide rings on both sides of the fixed clamping plate 4032, and the upper ends of the fixed rods 4035 are elastically connected to the guide rings through connecting springs 4036. In the present invention, by providing a telescopic clamping plate that can slide upward at the bottom, when the stock storage structure 4 places, picks up and feeds some of the fed wood, when the space height occupied by the two groups of single-depth forks 304 is higher than the bottom height of the telescopic clamping plate, at this time the movable clamping plate 4033 can slide upward and be received at the bottom of the fixed clamping plate 4032 to avoid the situation of jamming between the telescopic clamping plate and the single-depth forks 304.

[0053] In summary, in the present invention, a plurality of rotatable and extendable movable inserts 3041 are installed on the uppermost bearing plates of the two groups of single-depth forks 304 of the feeding structure 3. When the two groups of single-depth forks 304 are feeding a wooden pallet, the uppermost bearing plate can be driven by the two groups of single-depth forks 304 to extend and insert into the bottom of the corresponding wooden pallet. With the vertical upward movement of the feeding structure 3 and the reset movement of the bearing plate, the picking operation of the wooden pallet is realized. At the same time, when only some of the wood needs to be fed, the plurality of movable inserts 3041 can be driven to rotate and extend. Driven by the horizontal movement of the single-depth fork 304, the movable insert 3041 can be inserted into the bottom of the corresponding part of the feeding wood to support the feeding wood. At this time, there is no need to pick out the entire wooden pallet, and the flexible feeding operation of the wood is completed;

[0054] At the same time, in the present invention, a storage structure 4 is arranged on one side of the feeding structure 3. After the feeding structure 3 transports the wood in the three-dimensional warehouse 1, it can be placed in the storage structure 4.
