Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material stacking, in particular to a wood dryer discharge automatic stacking mechanism. BACKGROUND

[0002] In the process of wood product processing, wood needs to be dried to remove moisture and prolong its service life. During the drying process of wood, as the internal moisture of wood gradually evaporates, the wood fibers will also shrink. Due to the uneven distribution of moisture content in different regions inside the wood and the anisotropy of the structure, internal stress is generated between them, which causes the wood to warp and deform. This in turn leads to the fact that the wood cannot be stacked flat when stacking, not only causing large gaps between the wood, occupying stacking space, but also affecting the stability and neatness of the stack, increasing the risk of stack collapse. SUMMARY

Also, features described in relation to some examples can be combined in other examples.

[0074] Reference will now be made to Figure 1 and Figure 2The application discloses a wood drying machine discharging automatic stacking mechanism, which comprises a lower buckle plate conveying belt 1, an upper buckle plate conveying belt 2, an assembling table 5, a material receiving and sorting mechanism 6, a lower warped plate conveying unit 7, an upper warped plate conveying unit 8, a stacking rack 11 and a moving mechanism 12; the lower buckle plate conveying belt 1 is arranged on one side of the assembling table 5 and is used for conveying the lower buckle plate 3 to the assembling table 5; the upper buckle plate conveying belt 2 is arranged on one side of the assembling table 5 and is located directly above the lower buckle plate conveying belt 1 and is used for conveying the upper buckle plate 4; the material receiving and sorting mechanism 6 is arranged at the discharging end of the wood drying machine and is used for sorting the lower warped plate 9 and the upper warped plate 10 according to the warped direction of the discharged wood; the lower warped plate conveying unit 7 is arranged between the material receiving and sorting mechanism 6 and the assembling table 5 and is used for conveying the lower warped plate 9 sorted by the material receiving and sorting mechanism 6 to the assembling table 5; the upper warped plate conveying unit 8 is arranged between the material receiving and sorting mechanism 6 and the assembling table 5 and is located directly above the lower warped plate conveying unit 7 and is used for conveying the upper warped plate 10 sorted by the material receiving and sorting mechanism 6 to the assembling table 5; the stacking rack 11 is located on the side, away from the material receiving and sorting mechanism 6, of the assembling table 5 and is used for stacking the buckled lower warped plate 9 and the upper warped plate 10; and the moving mechanism 12 is arranged above the assembling table 5 and is used for moving the upper buckle plate 4 on the upper buckle plate conveying belt 2 to the assembling table 5 to complete buckling with the lower buckle plate 3 to form a buckled piece and moving the buckled piece into the stacking rack 11.

[0075] Specifically, the discharging end of the wood drying machine conveys the dried wood to the material receiving and sorting mechanism 6, the material receiving and sorting mechanism 6 detects the warped direction of the wood, when the two ends of the wood are warped downward, the wood is defined as the lower warped plate 9, the material receiving and sorting mechanism 6 distributes the lower warped plate 9 to the lower warped plate conveying unit 7, similarly, when the two ends of the wood are warped upward, the wood is defined as the upper warped plate 10, and the material receiving and sorting mechanism 6 distributes the upper warped plate 10 to the upper warped plate conveying unit 8.

[0076] In a complete cycle, first, the lower buckle plate conveying belt 1 conveys a group of lower buckle plates 3 to the assembling table 5, then the lower warped plate conveying unit 7 conveys a group of lower warped plates 9 into the lower buckle plates 3 on the assembling table 5, next the moving mechanism 12 moves a group of upper buckle plates 4 on the upper buckle plate conveying belt 2 to above the assembling table 5, then the upper warped plate conveying unit 8 conveys a group of upper warped plates 10 into the upper buckle plates 4 above the assembling table 5, the moving mechanism 12 buckles the upper buckle plates 4 with the lower buckle plates 3 to form a group of buckled pieces for encapsulating the lower warped plates 9 and the upper warped plates 10, and finally the moving mechanism 12 moves the buckled pieces into the stacking rack 11 to complete the stacking.

[0077] It should be noted that in actual application, the lower and upper curved plate conveying units 7 and 8 have a certain height difference in the vertical direction, so that the upper and lower curved plates 10 and 9 distributed in the up-down direction will not interfere with each other during operation; in addition, the conveying speed of the lower and upper curved plate conveying units 7 and 8 can be controlled, so that the lower and upper curved plates 9 and 10 can smoothly reach the designated position on the assembly table 5;

[0078] It is worth noting that the present application makes full use of the characteristics that after wood drying, the two ends of the wood will be warped to one side due to the shrinkage of wood fibers. Since the state of the warped wood entering the material receiving and sorting mechanism 6 is random, the wood is sorted according to the direction of the wood warping, and the lower and upper curved plates 9 and 10 are matched one by one, with the lower curved plate 9 located below and the upper curved plate 10 located above. The lower and upper buckling plates 3 and 4 are pressed and buckled to the matched lower and upper curved plates 9 and 10, thereby pressing and flattening the lower and upper curved plates 9 and 10, saving subsequent stacking space, improving stacking stability, and preventing the stack from collapsing. At the same time, the lower and upper buckling plates 3 and 4 are used to pressurize the lower and upper curved plates 9 and 10 to eliminate internal stress of the wood, improve the flatness of the wood, and facilitate subsequent processing.

[0079] In an embodiment, referring to Figure 3 , for the buckling process of the lower and upper curved plates 9 and 10, the lower and upper curved plates 9 and 10 are placed between the matched lower and upper buckling plates 3 and 4, with the upper curved plate 10 located above the lower curved plate 9. A vertical downward pressure is applied to the upper buckling plate 4, and the lower and upper buckling plates 3 and 4 respectively apply pressure to the two ends of the lower and upper curved plates 9 and 10, while the middle parts of the lower and upper curved plates 9 and 10 are in contact with each other. Thus, the lower and upper curved plates 9 and 10 are subjected to a torque opposite to the direction of their warping, thereby gradually reducing the warping degree of the lower and upper curved plates 9 and 10 until the lower and upper buckling plates 3 and 4 are buckled and the lower and upper curved plates 9 and 10 are completely flattened to form a set of buckling pieces.

[0080] Referring to Figure 4 and Figure 5 , the lower buckling plate 3 comprises a lower plate body 31, and a lower buckling groove 32 for accommodating the lower curved plate 9 is arranged above the lower plate body 31; the upper buckling plate 4 comprises an upper plate body 41, and an upper buckling groove 42 for accommodating the upper curved plate 10 is arranged below the upper plate body 41; the lower plate body 31 and the upper plate body 41 are detachably connected by a buckling assembly.

[0081] Before buckling, a group of lower buckling plates 9 is transported into the lower buckling groove 32 of the lower plate body 31 by the lower buckling plate conveying unit 7, and a group of upper buckling plates 10 is transported into the upper buckling groove 42 of the upper plate body 41 by the upper buckling plate conveying unit 8; after buckling, the lower buckling plate 9 and the upper buckling plate 10 are completely limited in the buckling cavity formed by the lower buckling groove 32 and the upper buckling groove 42.

[0082] Further, please refer to Figure 6 and Figure 7 , the buckling assembly comprises a chamber 34, a guide rod 36, a sliding frame 37, a spring 39 and a protrusion 44; the chamber 34 is opened in the lower plate body 31, and a plurality of slots 35 are arranged above the chamber 34; the guide rod 36 is horizontally fixed in the chamber 34; the sliding frame 37 is slidingly sleeved on the guide rod 36 and one end of the sliding frame 37 extends out of the chamber 34, and a push plate 38 corresponding to each slot 35 is arranged on the sliding frame 37; the spring 39 is arranged in the chamber 34 and away from the extended end of the sliding frame 37; the protrusion 44 is arranged on the upper plate body 41 and corresponds to each slot 35, and a wedge-shaped block 45 elastically extending and retracting is arranged on one side of the protrusion 44;

[0083] Specifically, please refer to Figure 8 and Figure 9 , during the buckling process of the upper buckling plate 4 and the lower buckling plate 3, the protrusion 44 is inserted into the corresponding slot 35, and the wedge-shaped block 45 elastically retracts into the protrusion 44 when passing through the slot 35, and when the upper buckling plate 4 and the lower buckling plate 3 are completely buckled, the wedge-shaped block 45 also completely enters the chamber 34 and elastically extends out of the protrusion 44, so as to use the extended wedge-shaped block 45 to buckle and lock the upper buckling plate 4 and the lower buckling plate 3; when it is necessary to release the buckling state of the lower buckling plate 3 and the upper buckling plate 4, the sliding frame 37 is pushed into the chamber 34, so that the sliding frame 37 slides along the guide rod 36 and drives the spring 39 to compress, and the push plate 38 on the sliding frame 37 pushes the corresponding wedge-shaped block 45 to retract into the protrusion 44 again, so that the protrusion 44 can be pulled out of the corresponding slot 35, and the upper buckling plate 4 and the lower buckling plate 3 can be separated; the sliding frame 37 can be reset under the elastic force of the spring 39.

[0084] In another embodiment, please refer to Figure 10 , the lower buckling plate conveying unit 7 comprises a lower frame body 71, a lower conveying belt 72 rotatably installed on the lower frame body 71 and a lower conveying motor 73 fixedly installed on the lower frame body 71; the lower conveying motor 73 is used to drive the lower conveying belt 72 to move, and the lower conveying belt 72 is used to carry and convey the lower buckling plate 9; the upper buckling plate conveying unit 8 comprises an upper frame body 81, an upper conveying belt 82 rotatably installed on the upper frame body 81 and an upper conveying motor 83 fixedly installed on the upper frame body 81; the upper conveying motor 83 is used to drive the upper conveying belt 82 to move, and the upper conveying belt 82 is used to carry and convey the upper buckling plate 10;

[0085] Specifically, the wood sorting mechanism 6 sorts the wood and distributes the wood according to the warping direction of the wood, wherein the lower warped board 9 is distributed onto the lower conveying belt 72 and conveyed to the side of the assembly table 5 by the lower conveying belt 72; and the upper warped board 10 is distributed onto the upper conveying belt 82 and conveyed to the side of the assembly table 5 by the upper conveying belt 82.

[0086] Further, considering the warping characteristics of the lower warped board 9 and the upper warped board 10, if the center of gravity of the lower warped board 9 and the upper warped board 10 deviates during the conveying process, the lower warped board 9 and the upper warped board 10 may be laterally misaligned with the lower buckle plate 3 and the upper buckle plate 4, and when the deviation is large, the lower warped board 9 and the upper warped board 10 may not be able to smoothly enter the lower buckle plate 3 and the upper buckle plate 4; therefore, in order to ensure the accuracy and stability of the subsequent buckling process, the deviation of the lower warped board 9 and the upper warped board 10 during the conveying process to the assembly table 5 should be minimized as much as possible. In this embodiment, please refer to Figure 11 At the contact point between the lower conveying belt 72 and the lower warped board 9, the central axis of the lower conveying belt 72 is perpendicular to the tangent of the lower warped board 9 at the contact point; similarly, at the contact point between the upper conveying belt 82 and the upper warped board 10, the central axis of the upper conveying belt 82 is perpendicular to the tangent of the upper warped board 10 at the contact point.

[0087] Since the central axis of the lower conveying belt 72 on both sides is perpendicular to the tangent of the lower warped board 9 at the corresponding contact point, the support force exerted by the lower conveying belt 72 on the lower warped board 9 during horizontal conveying is also perpendicular to the tangent of the contact point, so that no tangential force is generated at the contact point, and the lower warped board 9 can be effectively prevented from deviating to one side. Similarly, since the central axis of the upper conveying belt 82 on both sides is perpendicular to the tangent of the upper warped board 10 at the corresponding contact point, the support force exerted by the upper conveying belt 82 on the upper warped board 10 during horizontal conveying is also perpendicular to the tangent of the contact point, so that no tangential force is generated at the contact point, and the upper warped board 10 can be effectively prevented from deviating to one side.

[0088] In an embodiment, please refer to Figure 12 and Figure 13 The wood sorting mechanism 6 includes a wood receiving frame 61, a sorting plate 63, a sorting electric cylinder 65, and a sorting inductor 66. The wood receiving frame 61 is symmetrically provided with a chute 62 on both sides. The sorting plate 63 is provided with a pin shaft 64 movably embedded in the chute 62 at one end and located between the lower warped board conveying unit 7 and the upper warped board conveying unit 8 at the other end. The sorting electric cylinder 65 is hingedly connected to the wood receiving frame 61 at one end and hingedly connected to the sorting plate 63 at the other end. The sorting inductor 66 is arranged at the center of the upper end surface of the sorting plate 63 and used for detecting the warping direction of the wood.

[0089] Specifically, after the wood at the discharge end of the wood drying machine falls on the sorting plate 63, the warping direction of the wood is detected by the sorting sensor 66; and the sorting plate 63 is switched from the initial position to the sliding position and the overturning position according to the detection result;

[0090] Please refer to Figure 14 When the sorting plate 63 is in the initial position, the sorting plate 63 is in a horizontal state and the pin shaft 64 is located at one end of the sliding groove 62 away from the assembly table 5, at this time, the telescopic rod of the sorting electric cylinder 65 is also in the initial state, and the position of the telescopic rod of the sorting electric cylinder 65 at this time is recorded as the zero position;

[0091] Please refer to Figure 15 When the sorting sensor 66 detects that the wood warps upward, the telescopic rod of the sorting electric cylinder 65 is extended forward from the zero position, and due to the restriction of the upward warping plate conveying unit 8, the end of the sorting plate 63 away from the pin shaft 64 cannot be overturned upward, so that the sorting plate 63 moves horizontally forward to the sliding position, and the pin shaft 64 slides horizontally to the other end of the sliding groove 62, so as to send the upward warping plate 10 to the upward warping plate conveying unit 8;

[0092] Please refer to Figure 16 When the sorting sensor 66 detects that the wood warps downward, the telescopic rod of the sorting electric cylinder 65 is retracted backward from the zero position, and the sorting plate 63 overturns downward around the pin shaft 64 to the overturning position, so as to send the downward warping plate 9 to the downward warping plate conveying unit 7;

[0093] It should be noted that, according to the detection result of the warping direction of the wood, the state of the sorting plate 63 is switched by the extension of the sorting electric cylinder 65, so that the downward warping plate 9 and the upward warping plate 10 are sorted flexibly, and the sorting efficiency is high;

[0094] The sorting electric cylinder 65 can be selected according to the actual application conditions, and details are not described herein;

[0095] In addition, for the detection process of the sorting sensor 66, since the state of the wood falling on the sorting plate 63 is random, the wood may warp upward or downward, when the wood warps upward, the middle part thereof is in contact with the upper end surface of the sorting plate 63, at this time, the sorting sensor 66 can detect the wood, so as to define the wood as the upward warping plate 10; when the wood warps downward, the two ends thereof are in contact with the upper end surface of the sorting plate 63, at this time, the sorting sensor 66 cannot detect the wood, so as to define the wood as the downward warping plate 9; according to the above characteristics, the detection distance of the sorting sensor 66 can be correspondingly set, so that the wood can be detected when warping upward, and the wood cannot be detected when warping downward, so as to realize the detection and sorting of the downward warping plate 9 and the upward warping plate 10.

[0096] Further, please refer to Figure 1 and Figure 2Further comprising a controller 13 for acquiring the detection result of the sorting sensor 66 and controlling the sorting plate 63 to switch states according to the detection result;

[0097] When the sorting sensor 66 detects that the wood is the lower warped board 9, the sorting cylinder 65 is controlled to retract to drive the sorting plate 63 to overturn downward, so that the sorting plate 63 is switched from the initial position to the overturned position; when the sorting sensor 66 detects that the wood is the upper warped board 10, the sorting cylinder 65 is controlled to extend to drive the sorting plate 63 to slide horizontally, so that the sorting plate 63 is switched from the initial position to the sliding position;
