Description

Technical Field

[0001] The invention relates to a log processing system capable of increasing efficiency and reducing manpower, and belongs to the technical field of log processing. Background Art

[0002] In the prior art, processing a log into the required board requires multiple processing steps, such as removing the round edge material, cutting the board from the log after the initial processing, etc. At present, the domestic processing method for logs is mostly to use a band saw machine assisted by manual methods to cut the logs and then process them into raw materials or integrated materials. However, the demand for integrated materials is constantly expanding in the market, and the processing technology and equipment are relatively backward, which cannot meet the market demand in a timely manner.

[0003] like Figure 1 As shown, in the current market, the scheme for opening materials is mostly to load the materials through the positive and negative operators of the band saw machine, clamp the logs on the band saw machine, and use the band saw to cut the logs into board skins, edge boards, and square boards. Then, the board skins are piled up in a waste pile or other uses by manual transportation. Then, the edge boards are transported to the second band saw machine by manual transportation, and the positive and negative operators trim the edge boards and skins into standard boards on the second band saw machine. Finally, the square boards are transported to the third equipment, the square material saw machine, by manual transportation, and the positive and negative operators use the square material saw machine to cut the square board into standard boards. It takes seven manual positions to saw logs into standard boards.

[0004] In the above process, not only is the manual transfer distance long, time-consuming and labor-intensive; at the same time, the number of personnel required is large. One person is needed to load the sports car, one person is needed to operate and unload the sports car, one person is needed to feed and unload the second saw, and one person is needed to load and unload the edge cleaning machine.

DETAILED DESCRIPTION

[0051] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] in, Figure 2 The arrow direction in FIG. 1 represents the sawing direction of the log 17 .

[0053] See also Figure 2-24A log processing system with increased efficiency and reduced manpower comprises a feeder 1, a sports car 2, a vertical band saw 3, a material holding device 4, a side shift conveyor 5, a conveyor belt, a material board transition frame 81, a return material conveyor frame 82, an edge cleaning and material modification integrated machine 83, a square wood multi-blade saw 84, a pit 85 and a wood chip conveyor belt 86; the feeder 1 is located on one side of the sports car 2; along the sawing direction of the log 17, the band saw 3 and the conveyor belt are sequentially arranged behind the feeder 1; the material holding device 4 is arranged above the outer side of the front part of the conveyor belt; the side shift conveyor 5 is arranged in the middle of the conveyor belt, and is arranged on the same side as the material holding device 4; a plurality of material board transition frames 81 are arranged at intervals On the outside of the side-shift conveying device 5; the return material conveying frame 82, the edge cleaning and material modification integrated machine 83, another return material conveying frame 82 and the square wood multi-blade saw machine 84 are arranged in sequence on the outside of the rear part of the conveyor belt along a direction perpendicular to the sawing direction of the log 17; the material plate transition frame 81 is arranged corresponding to the return material conveying frame 82, the edge cleaning and material modification integrated machine 83 and the square wood multi-blade saw machine 84; a pit 85 is opened under the band saw machine 3, the conveyor belt, the return material conveying frame 82, the edge cleaning and material modification integrated machine 83 and the square wood multi-blade saw machine 84, and the pit 85 is connected in an L shape; the wood chip conveyor belt 86 is arranged in the pit 85.

[0054] According to the above description, the log processing system with increased efficiency and reduced manpower includes a feeder 1, a sports car 2, a vertical band saw 3, a material holding device 4, a side shift conveyor 5, a conveyor belt, a material board transition frame 81, a return material conveyor frame 82, an edge cleaning and material modification integrated machine 83, a square wood multi-blade saw 84, a pit 85, and a wood chip conveyor belt 86. The band saw 3, the material holding device 4, the side shift conveyor 5, and the conveyor belt together constitute the band saw machine discharge conveyor line. The log 17 is placed on the feeder 1, and the feeder 1 can convey the log 17 to the sports car 2, and the sports car 2 clamps the log 17 to the band saw 3 for sawing. The material holding device 4 is arranged behind the band saw 3, which can provide elastic force to press the board material that has been cut but not completely cut off from the log 17 to the log 17, and replaces manual material holding with a mechanical structure, saving human resources, and also reducing the hidden danger of injury from the band saw 3. The conveyor belt is arranged along the sawing direction of the log 17, and can transport the cut board material (i.e., the square board 36 or the curved side board 37). The side shift conveying device 5 is arranged in the middle of the conveyor belt, which can lift the square board 36 on the conveyor belt and move it to the board transition rack 81, while the curved side board 37 flows along the conveyor belt to the end. The square board 36 is sent to the middle of the edge cleaning and material modification integrated machine 83 for edge cleaning and slicing; and the curved side board 37 is sent to the side of the edge cleaning and material modification integrated machine 83 for board skin modification. After the square board 36 and the curved side board 37 are processed, they can be transported to the return board transition rack 81 through the return material conveyor rack 82, and then moved to the square wood multi-blade saw machine 84 to be cut into standard boards. The wood chips generated during the sawing process can be collected through the pit 85, and finally processed in a centralized and unified manner through the wood chip conveyor belt 86.

[0055] In the present application, a material plate transition rack 81, a return material conveying rack 82, an edge cleaning and material modification integrated machine 83, and a square wood multi-blade saw machine 84 are used. The material plate transition rack 81 is used to transfer the cut plates (i.e., square material plates 36 or curved edge plates 37), or to transport the processed square material plates 36 (or curved edge plates 37), which can reduce the labor intensity of workers. The operator in the feeding direction of the integrated machine for edge cleaning and material modification 83 can transport the sheet materials from the side shift conveying device 5 to the integrated machine for edge cleaning and material modification 83 through the sheet transition rack 81. The middle part of the integrated machine for edge cleaning and material modification 83 can perform edge cleaning and slice the square sheet materials 36, while the side part of the integrated machine for edge cleaning and material modification 83 can perform board skin modification on the curved edge sheet materials 37. Then the operator in the discharging direction of the integrated machine for edge cleaning and material modification 83 returns the processed sheet materials to the front of the integrated machine for edge cleaning and material modification 83 through the return conveying racks 82 on both sides. The operator in the feeding direction of the integrated machine for edge cleaning and material modification 83 then transfers the processed sheet materials through the sheet transition rack 81 to the square wood multi-blade saw 84 to cut them into standard sheets, and finally the operator in the discharging direction of the square wood multi-blade saw 84 receives the materials. In this way, the operators of the edge cleaning and material modification machine 83 and the feeding direction of the square wood multi-blade saw machine 84 can be combined into one person, which reduces the manpower of one person on the basis that the original two-saw machine and the square material saw machine both require positive and negative two operators.

[0056] In particular, one operator is set for each of the discharging directions of the integrated edge cleaning and material modification machine 83 and the square wood multi-blade saw machine 84. This is mainly because the operator in the discharging direction not only needs to receive the materials, but also needs to stack the processed boards. The labor intensity is greater than that in the feeding direction. Therefore, two people are required to cooperate and take turns to receive and stack the materials to reduce the workload.

[0057] In particular, for the convenience of transportation, rollers are rotatably fixed on the upper ends of the material sheet transition frame 81 and the return material conveying frame 82.

[0058] In particular, in order to save space and reduce floor space, the feeder 1, band saw machine 3, material holding device 4, side shift conveying device 5, conveyor belt, material plate transition rack 81, return material conveying rack 82, edge cleaning and material modification integrated machine 83, square wood multi-blade saw machine 84, pit 85 and wood chip conveyor belt 86 are all arranged on the same side of the sports car 2.

[0059] Particularly, an upward section is provided at the end of the wood chip conveyor belt 86 , and the upward section is higher than the surface of the pit 85 .

[0062] According to the above description, the feeder 1 includes a feed frame 11, a feed chain 12, a J-shaped feed claw 13, a rotating shaft 14, a feed cylinder 15 and a feed motor 16. The feed frame 11 plays a supporting role; the feed motor 16 drives the feed chain 12 to convey the logs 17 forward; the feed cylinder 15 drives the J-shaped feed claw 13 to swing around the rotating shaft 14. When the piston rod of the feeding cylinder 15 extends out, the hook of the J-shaped feeding claw 13 is higher than the feeding chain 12, and the log 17 is blocked by the hook and cannot enter the J-shaped feeding claw 13; when the piston rod of the feeding cylinder 15 retracts, the hook of the J-shaped feeding claw 13 is lower than the feeding chain 12, while the height of the outer end of the J-shaped feeding claw 13 is higher than the feeding chain 12. At this time, the feeding chain 12 can transport the log 17 into the J-shaped feeding claw 13 to wait for material. When the piston rod of the feeding cylinder 15 extends out next time, the log 17 can naturally roll into the sports car 2 and be clamped by the sports car 2 to the band saw machine 3 for sawing.

[0063] Furthermore, a feeding mechanism is provided on the sports car 2; the feeding mechanism includes a feeding seat 21, a feeding guide rail 22, a feeding table 23, a feeding motor 24, a vertical cylinder 25, a horizontal cylinder 26 and a J-shaped claw 27; the lower end of the feeding seat 21 is fixed on the sports car 2, the feeding guide rail 22 is fixed on the upper end of the feeding seat 21, and the lower end of the feeding table 23 is slidably sleeved on the feeding guide rail 22; the feeding guide rail 22 is perpendicular to the sawing direction of the log 17; the feeding motor 24 is provided On the feed table 23, the feed table 23 is driven to move on the feed guide rail 22; the upper end of the vertical cylinder 25 is slidably sleeved on the upper part of the feed table 23, and the piston rod of the lower end of the vertical cylinder 25 is fixed to the lower part of the feed table 23; the horizontal transverse cylinder 26 is fixed to the vertical cylinder 25, and the piston rod of the transverse cylinder 26 is fixed to the J-shaped claw 27; the J-shaped claw 27 is horizontally arranged, and the hook of the J-shaped claw 27 is downward and toward the feeder 1.

[0064] According to the above description, a feeding mechanism is provided on the sports car 2, which is used to adjust the position of the log 17 on the sports car 2. The feeding mechanism includes a feeding seat 21, a feeding guide rail 22, a feeding table 23, a feeding motor 24, a vertical cylinder 25, a horizontal cylinder 26 and a J-shaped claw 27. The feeding seat 21 is fixed on the sports car 2; the feeding table 23 can slide on the feeding seat 21 through the feeding motor 24 and the feeding guide rail 22; the vertical cylinder 25 is sleeved on the feeding table 23, the horizontal cylinder 26 is fixed on the vertical cylinder 25, and the J-shaped claw 27 is fixed on the piston rod of the horizontal cylinder 26, and the J-shaped claw 27 is used to clamp the log 17. The height of the J-shaped claw 27 clamping the log 17 can be adjusted through the vertical cylinder 25; the width of the J-shaped claw 27 clamping the log 17 can be adjusted through the horizontal cylinder 26. In this way, an appropriate position is selected to achieve the best clamping effect on the log 17.

The front conveyor belt 6 includes a front frame 61, a front roller 62, a front motor 63 and a discharge belt 64. The front roller 62 is driven by the front motor 63; the discharge belt 64 is used to transport the edge skin or triangular material cut by the saw blade 32. The middle and rear sections of the front frame 61 are provided with an avoidance groove 68 for the side shift conveyor device 5 to pass through. The avoidance groove 68 is mainly used to avoid the position of the side shift conveyor device 5 (i.e., the conveying platform 52 and the material storage platform 53), so that the conveying platform 52 can move up and down freely and lift the square material plate 36. The rear conveyor belt 7 includes a rear frame 71, a rear roller 72 and a rear motor 73. The rear roller 72 is driven by the rear motor 73.

The limit plate 76 is mainly used to separate the square material plate 36 and the arc side plate 37 cut from the log 17. When the arc-shaped side plate 37 cut from the log 17 falls into the conveyor belt, the piston rod of the swing cylinder 74 is controlled to extend, so that the upper end height of the limit plate 76 is lower than the rear roller 72, and the arc-shaped side plate 37 can smoothly pass through the conveyor belt and enter the rear conveyor belt 7 to wait for material, and then be transferred or to the next process; when the square material plate 36 cut from the log 17 falls into the conveyor belt, the piston rod of the swing cylinder 74 is controlled to retract, so that the upper end height of the limit plate 76 is higher than the rear roller 72, and the front end of the square material plate 36 will be blocked by the limit plate 76 and cannot move forward, so that it stays at the end of the front conveyor belt 6, and then the square material plate 36 can be lifted up and transferred to the storage platform 53 through the side shift conveying device 5, thereby realizing the separation of the square material plate 36 and the arc-shaped side plate 37.

[0079] In particular, the limiting plate 76 is preferably located between the first two rear rollers 72 , or between the second and third rear rollers 72 .

[0082] Working principle of the present invention:

[0083] See also Figure 2-24 When the log processing system with increased efficiency and reduced manpower is working, first, the log 17 is placed on the feeding frame 11 of the feeder 1, and is transported by the feeding chain 12 to the J-shaped feeding claw 13; then the J-shaped feeding claw 13 sends the log 17 to the sports car 2 at intervals, and clamps it through the J-shaped claw 27. Then, the sports car 2 moves along the guide rail to the band saw machine 3, and the saw blade 32 starts to cut the log 17. At the same time, the holding device 4 starts to work, and the holding cylinder 44 pushes out the holding slide 42, so that the holding roller 47 is located above the front conveyor belt 6. Then, as the sports car 2 moves forward and the sawing work of the log 17 proceeds, the board material on the log 17 that has been cut but not completely cut begins to contact the holding roller 47. Through the support of the gas spring 45, the holding roller 47 will press the board material tightly against the log 17, and the board material is pressed against the log 17 to achieve the holding work. After the sawing of the log 17 is completed, the sports car 2 is reset through the track, and the holding cylinder 44 drives the holding slide 42 to reset, preparing for the next round of sawing; and the completely sawn sheet material falls onto the front conveyor belt 6 under the action of its own gravity, moves forward through the rotation of the front roller 62, and can be transported along the edge through the roller spiral teeth 67.

[0084] When the curved side board 37 is cut from the log 17, the lifting cylinder 55 of the side shift conveying device 5 does not work, and the conveying platform 52 is still located below the front roller 62; the swing cylinder 74 of the rear conveyor belt 7 does not work, and the upper end height of the limit plate 76 is still lower than the height of the rear roller 72. Therefore, the curved side board 37 can pass through the rear conveyor belt 7 normally, and after being conveyed to the end of the rear conveyor belt 7, it is moved away by the worker. Finally, all parts are reset and wait for the next round of work.

[0085] When the square sheet 36 is cut from the log 17, the swing cylinder 74 of the rear conveyor belt 7 works, the piston rod of the swing cylinder 74 extends, the limit plate 76 swings around the hinge shaft 75, and the upper end of the limit plate 76 is higher than the rear roller 72, so the front end of the square sheet 36 is blocked by the limit plate 76 and cannot move forward, and stays at the end of the front conveyor belt 6. Then, the lifting cylinder 55 of the side shift conveying device 5 works, the piston rod of the lifting cylinder 55 extends, driving the conveying platform 52 to rise in height, higher than the front roller 62, and the square sheet 36 staying on the front conveyor belt 6 is lifted by the conveying sprocket 523 on the conveying platform 52 and leaves the front conveyor belt 6. Then the power motor 56 works, driving the conveying sprocket 523 to work through the transmission effect, and the square material plate 36 on the conveying sprocket 523 is transported to the storage platform 53, and slides to the front of the supporting square tube 54 through the rolling cooperation with the storage bearing 531, and then is moved away by the worker. Finally, all parts are reset and wait for the next round of work.

[0086] After the square sheet 36 and the curved side board 37 are separated, the square sheet 36 is moved to the sheet transition rack 81 by the worker, and then the square sheet 36 is moved to the middle of the edge cleaning and material modification machine 83 for edge cleaning and slicing; while the curved side board 37 is moved to the side of the edge cleaning and material modification machine 83 for the board skin modification process. The processed square sheet 36 and curved side board 37 can be returned to the sheet transition rack 81 again through the return material conveyor rack 82 set on both sides of the edge cleaning and material modification machine 83. Finally, the worker moves the processed square sheet 36 and curved side board 37 through the sheet transition rack 81 to the middle of the square wood multi-blade saw machine 84, and finally cuts them into standard boards.
