Description

Technical Field

[0001] The invention relates to wood processing technology, and in particular to a material combing mechanism for a plate arrangement assembly line. Background Art

[0002] Planking refers to stacking multiple pieces of wood together in a specific way for easy packaging and transportation. In wood processing production, it is necessary to process boards of roughly the same size, shape and quality for easy planking. The process of processing logs into boards mainly includes log pretreatment, log sawing, trimming and polishing. In the log sawing process, the longer logs are first cut into sections, and then the left and right ends of the log sections are sawed to form vertical square materials. The square materials are then pushed down and reversed to become horizontal square materials, and then the other two ends of the horizontal square materials are sawed. In this way, the better quality part in the middle of the log section can be retained, and it is also convenient to cut the log section into sheets.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-10As shown, an embodiment of the present invention provides a material combing mechanism for a plate arrangement assembly line, comprising a material conveying line 1, on which a plurality of centering components 2 are installed, wherein the centering components 2 include two relatively arranged movable bases 21, a driving unit 22 drives the two movable bases 21 to perform relative movement to achieve centering of the square material, a connecting shaft 23 is fixedly connected to the upper end of the movable base 21, a contact cylinder 24 is provided on the outer rotating sleeve of the connecting shaft 23, a push rod 25 is installed on the top of one of the two relatively arranged connecting shafts 23, and the push rod 23 extends in a direction close to the square material, and in the stroke of relative movement of the two movable bases 21, it includes a first stroke in which the push rod 25 pushes the top of the square material to push down the square material and a second stroke in which the two movable bases 21 clamp the square material to achieve centering.

[0031] Specifically in this embodiment, the transportation direction of the square material is defined as the left-right direction, and the forward direction of the square material is the right direction ( Figure 1The state shown), on the material conveying line 1, the left and right end faces of the vertical square material are cut off so that the square material has a specific length, and the front and rear end faces of the vertical square material are also cut off so that the square material gradually changes from a cylindrical structure to a rectangular structure. The material conveying line 1 is used to transport the square material so that it can enter the next working link; the centering component 2 is used to center the pushed square material (horizontal state) so that it can be transported along the middle position of the material conveying line 1 to the next working link. The centering components 2 are multiple, preferably two, so that the centering effect of the square material can be ensured; the movement direction of the movable base 21 is defined as the front and rear directions, and the movable base 2 The movable base 21 is preferably a square block structure, each two movable bases 21 are driven by a driving unit 22, and the movable base 21 can only move relatively close to or away from each other, the connecting shaft 23 is a cylindrical structure, and the connecting shaft 23 is detachably fixed on the movable base 21, and the contact cylinder 24 is mainly used to contact the two ends of the square material for centering, and the contact cylinder 24 is rotatably arranged on the connecting shaft 23 so that the contact cylinder 24 can rotate during centering to avoid fixed clamping of the moving square material; a push rod 25 is installed on the top of one of the two relatively arranged connecting shafts 23, and preferably a push rod 25 is installed on the rear connecting shaft 23. Rod 25, the push rod 25 is preferably a square rod-shaped structure, the push rod 25 is mainly used to contact with the upper side of the rear end of the square material and push down the square material, that is, the height of the bottom of the push rod 25 is smaller than the height of the top of the square material. For different batches of square materials with different diameters, the connecting shaft 23 and the push rod 25 can be replaced to ensure that it can contact with the upper side of the rear end of the square material. Obviously, the push rod 25 extends in the direction close to the square material, that is, the front, to ensure that the push rod 25 contacts with the upper side of the rear end of the square material first; specifically, in the working process, in the first stroke, when the vertical square material enters the material conveying line 1, it continues to move to the right on the material conveying line 1, and when the vertical square material When the material moves to a specific position (multiple movable bases 21 can make relative movement and contact with the vertical square material), each driving unit 22 synchronously drives the two corresponding movable bases 21 to approach each other. At this time, the push rod 25 first contacts the upper side of the rear end of the square material and pushes down the vertical square material. The horizontal square material will no longer contact the push rod 25. During the second stroke, the movable base 21 continues to move, so that the multiple contact cylinders 24 on the front and rear sides contact with the horizontal square material and squeeze the square material to the center. In this way, the centering process of the square material is utilized to passively push down the vertical square material. No additional drive needs to be installed during this process, and slipping can be avoided.

[0032] In another embodiment provided by the present invention, the material conveying line 1 includes a conveying frame 11, on which a plurality of rollers 12 are rotatably mounted, and also includes a power unit, and the power unit is used to drive the plurality of rollers 12 to rotate to transport square materials. The power unit is a prior art, and it will not be elaborated on as long as it can make the plurality of rollers 12 rotate synchronously in the direction of transporting the square materials. The height of the upper end of the mobile base 21 is not greater than the height of the uppermost side of the roller 12, so as to avoid the mobile base 21 from contacting the square materials when they are close to each other.

[0033] In another embodiment provided by the present invention, the driving unit 22 includes a limiting base 221 horizontally installed on the conveying frame 11, and the limiting base 221 is preferably a square plate structure. The limiting base 221 is used to limit the movement of the mobile base 21. The extension direction of the limiting base 221 is parallel to the axis of the roller 12. The mobile base 21 is slidably installed on the limiting base 221. A bidirectional lead screw 222 is rotatably provided on the conveying frame 11. The bidirectional lead screw 222 is the prior art and will not be elaborated on. The two corresponding mobile bases 21 are respectively threadedly connected to the two ends of the bidirectional lead screw 222, so that when the bidirectional lead screw 222 rotates, the two mobile bases 21 move relative to or away from each other.

[0034] In another embodiment provided by the present invention, one end of the plurality of bidirectional screws 222 located outside the conveying frame 11 is fixedly connected with an I-shaped wheel 223, and a transmission belt 224 is connected between the plurality of I-shaped wheels 223. A driving motor 225 is installed on the conveying frame 11, and the output shaft of the driving motor 225 is axially connected to one of the I-shaped wheels 223. When the driving motor 225 is started, it drives one of the I-shaped wheels 223 to rotate, and the rotation of the I-shaped wheel 223 drives the transmission belt 224 to move, thereby causing the other plurality of I-shaped wheels 223 to rotate synchronously. In this way, the plurality of bidirectional screws 222 are driven to rotate synchronously, and the two movable bases 21 on the same bidirectional screw 222 are driven to move relative to each other.

[0035] In another embodiment provided by the present invention, guard plates are installed at both the front and rear ends of the conveying frame 11 , and the guard plates are used to prevent the square materials from sliding out of the conveying frame 11 .

[0036] In another embodiment of the present invention, an elastic connection layer is sleeved on the outer wall of the contact tube 24. The elastic connection layer is preferably a rubber ring. This is to prevent the contact tube 24 from being damaged during alignment with the square material, so that the contact tube 24 can be in elastic contact with the square material.

[0037] Obviously, in the case of only the push rod 25, pushing the upper side of the rear end of the vertical square material may cause the square material as a whole to slide axially on the roller 12. For this reason, in another embodiment of the present invention, a connecting block 231 is formed on the lower side of the connecting shaft 23 on the front side. It should be noted that the connecting block 231 does not extend out of the projection range of the contact cylinder 24 in the vertical direction (that is, the size of the connecting block 231 is smaller than the radius of the contact cylinder 24). This ensures that the contact cylinder 24 contacts the square material first and avoids the connecting block 231 from contacting the square material. The connecting block 231 is rotatably mounted with a bottom push rod 231 through a rotating shaft. 2. A torsion spring 233 is sleeved on the rotating shaft, and the torsion spring 233 is connected between the bottom push rod 232 and the connecting block 231. In the initial state, the bottom push rod 232 is in a horizontal state, and the torsion spring 233 is used to maintain the horizontal state of the bottom push rod 232. The bottom push rod 232 extends toward the direction close to the square material. Preferably, the bottom push rod 232 and the top push rod 25 have the same length, and the end faces of the bottom push rod 232 and the top push rod 25 that are close to each other are at the same distance from the vertical square material; the horizontal height of the upper end of the bottom push rod 232 is greater than the horizontal height of the top of the roller 12, so as to ensure that the bottom push rod 232 can contact the square material.

[0038] When the movable bases 21 on the front and rear sides perform relative movement, the top push rod 25 and the bottom push rod 232 also perform relative movement accordingly. At this time, the top push rod 25 and the bottom push rod 232 contact the vertical square material at the same time, and the top push rod 25 squeezes the upper side of the rear end of the vertical square material, and the bottom push rod 232 squeezes the lower side of the front end of the vertical square material. In this way, the vertical square material is subjected to the action of forces in opposite directions from top to bottom, which can ensure that the vertical square material is pushed down and avoid the phenomenon of axial sliding of the vertical square material as a whole on the roller 12. Moreover, when the vertical square material is pushed down, it will be pressed on the bottom push rod 232. At this time, under the action of the gravity of the square material, the end of the bottom push rod 232 close to the square material is squeezed and rotated downward and works on the torsion spring 233, and the horizontal square material The square material can still contact the roller 12 under the action of its own gravity. The bottom push rod 232 is designed in this way to avoid blocking the contact between the square material and the roller 12 under the premise that the bottom push rod 232 has a pushing effect, to ensure that the square material can contact the roller 12 and continue to move after being pushed down, and to make the horizontal square material maintain a horizontal state as much as possible. During the transportation of horizontal square materials (when the moving base 21 has not fully returned to its original position), the lower side of the front end of the square material will be squeezed on the inclined bottom push rod 232 and slide relative to the inclined bottom push rod 232. During this process, the lower side of the front end of the horizontal square material will be subjected to the oblique upward force provided by the torsion spring 233; at the same time, the square material after being pushed down will fall toward the bottom push rod 232, and the bottom push rod 232 and the torsion spring 233 can also be used to buffer the dumping process of the square material.

[0039] In addition, when the square material is not completely sawn into a square shape (that is, when the horizontal square material is not sawn again), the upper and lower sides of the front and rear ends are still curved surfaces. When the rotatable bottom push rod 232 contacts and squeezes the curved surface on the square material, the rotatable bottom push rod 232 may be directly squeezed downward into a tilted state, and it is impossible to apply pressure to the lower side of the front end of the vertical square material. For this reason, the present invention provides another embodiment, the bottom of the connecting block 231 is provided with a first movable groove 234, and the front side of the movable base 21 is provided with a second movable groove 235. The first movable groove 234 and the second movable groove 235 are preferably square grooves. The movable grooves 235 are relatively arranged, and a first elastic slide bar 236 is horizontally slidably penetrated in the second movable groove 235. The first elastic slide bar 236 extends in the direction close to the square material. There is a certain distance between the end of the first elastic slide bar 236 close to the square material and the end of the bottom push rod 232 close to the square material. The distance is defined as the push-down distance. The push-down distance is small, so that the first elastic slide bar 236 can be squeezed and moved immediately after the square material is pushed down. A first limit spring is connected between the first elastic slide bar 236 and the movable base 21 on the front side. The first limit spring is used to maintain the initial state of the first elastic slide bar 236. An L-shaped fixed spring is formed on the top of the first elastic slide bar 236. The positioning rod 237 (the L-shaped positioning rod 237 is actually an inverted L-shape) is formed by connecting a horizontal section and a vertical section. The horizontal section is located at the upper end of the vertical section close to the bottom push rod 232. The vertical section of the L-shaped positioning rod 237 is connected to the top of the first elastic sliding rod 236. The L-shaped positioning rod 237 slides horizontally in the second movable groove 235 and the first movable groove 234. The horizontal section of the L-shaped positioning rod 237 slides through the second movable groove 235 and extends toward the bottom push rod 232. The end of the bottom push rod 232 close to the L-shaped positioning rod 237 is arc-shaped. A positioning groove 238 is provided on the end of the bottom push rod 232 close to the L-shaped positioning rod 237. In the initial state, The horizontal section of the L-shaped positioning rod 237 is inserted into the positioning groove 238 under the elastic action of the first limit spring. When the L-shaped positioning rod 237 is inserted into the positioning groove 238, the bottom push rod 232 is in a locked state, and a docking rod 211 is formed on the movable base 21 on the rear side. The docking rod 211 and the first elastic slide bar 236 are correspondingly arranged. When the movable bases 21 on the front and rear sides move relative to each other, the docking rod 211 can contact the first elastic slide bar 236 and push the first elastic slide bar 236 to slide in the first movable groove 234; the horizontal section of the L-shaped positioning rod 237 is trapezoidal at one end close to the bottom push rod 232, which is convenient for the L-shaped positioning rod 237 to be inserted into the positioning groove 238.

[0040] When the square material in the vertical state is transported on the material conveying line 1, the movable base 21 on the front and rear sides is driven to move relative to each other. At this time, the bottom push rod 232 approaches the square material and gradually contacts the lower arc surface of the vertical square material. However, since the L-shaped positioning rod 237 is inserted into the positioning groove 238 at this time, the bottom push rod 232 is locked. Therefore, the bottom push rod 232 will not rotate, which can ensure the squeezing of the square material. The bottom push rod 232 continues to move. When the square material in the vertical state is pushed down, it should be noted that the time for the square material to be pushed down is extremely short. In this embodiment, the timing of the contact between the first elastic sliding rod 236 and the docking rod 211 can be controlled by adjusting the size of the pushing down spacing, so that the locking state of the bottom push rod 232 is changed synchronously when the square material is pushed down. The first elastic sliding rod 236 begins to contact the docking rod 211. At this time, the first elastic sliding rod 236 is squeezed and slides horizontally in the second movable groove 235 The first limit spring 232 is also synchronously squeezed, and the sliding of the first elastic slide bar 236 drives the L-shaped positioning rod 237 to slide synchronously. In this way, the L-shaped positioning rod 237 slides relative to the movable base 21, so that the horizontal section of the L-shaped positioning rod 237 leaves the positioning groove 238, so that the bottom push rod 232 is restored to a rotatable state. When the vertical square material is pushed down, the square material is still pressed on the rotatable bottom push rod 232; in summary, the bottom push rod 232 has a locked state and a rotatable state. The locked state is used to ensure that the bottom push rod 232 will not be squeezed downward when it contacts the curved surface of the square material, so as to ensure that the pressure exerted by the bottom push rod 232 on the lower side of the vertical square material will not be deflected; the rotatable state is used to prevent the bottom push rod 232 from blocking the contact between the square material and the roller 12, so as to maintain the horizontal state of the square material.

[0041] Furthermore, when the horizontal square material is transported on the material conveying line 1, the lower side of the front end of the square material will be squeezed on the inclined bottom push rod 232. Therefore, during the transportation process, the lower side of the front end of the horizontal square material will be subjected to the oblique upward force provided by the torsion spring 233, which may cause the horizontal square material to be slightly tilted, which is not conducive to subsequent sawing; moreover, when sawing the two ends of the horizontal square material, it is generally sawed by a rotating cutter. In this process, if no pressure is applied to the top of the horizontal square material, the sawing effect will be affected. For this reason, the present embodiment provides a further solution to solve the above problem. It should be noted that, unlike the above-mentioned embodiment, the present embodiment does not have a docking rod 211, and the connecting shaft 23 is not fixed on the movable base 21 at the rear side. The connecting shaft 23 is vertically slidably installed on the upper end of the movable base 21; a working cavity 261 is provided in the movable base 21 at the rear side, and a second elastic slide bar 262 is slidably penetrated in the working cavity 261, and the end of the second elastic slide bar 262 close to the square material extends to the outside of the movable base 21 at the rear side, and a second limit spring is connected between the second elastic slide bar 262 and the movable base 21. The second elastic slide bar 262 is connected to the movable base 21. 262 is arranged in correspondence with the first elastic slide bar 236. When the movable bases 21 on the front and rear sides approach each other, the second elastic slide bar 262 will contact the first elastic slide bar 236. The second limit spring is used to maintain the initial state of the second elastic slide bar 262. A rack 263 is fixed to one end of the second elastic slide bar 262 located in the working chamber 261. A circular groove is provided in the connecting shaft 23 on the rear side. A driving screw 264 is threadedly connected to the circular groove. The bottom of the driving screw 264 is rotatably installed in the working chamber 261. The lower side of the driving screw 264 is sleeved with a driving gear. Wheel 265, the driving gear 265 and the rack 263 are in a meshing state, the lower end of the push rod 25 is detachably fixed with a mounting seat near the side of the square material, the lower end of the mounting seat is provided with a working groove 266, two sliders 267 are slidably installed in the working groove 266, a top roller 268 is rotatably installed between the two sliders 267, an extrusion spring 269 is connected between the slider 267 and the working groove 266, the lower end of the top roller 268 extends to the bottom of the working groove 266, and the cooperation of the extrusion spring 269 and the slider 267 allows the top roller 268 to elastically squeeze the upper end of the square material in a horizontal state.

[0042] During the centering process, the movable bases 21 on the front and rear sides approach each other. When the top push rod 25 and the bottom push rod 232 cooperate to push the square material down, the first elastic slide bar 236 and the second elastic slide bar 262 begin to contact and squeeze each other, and the first limit spring and the second limit spring are also compressed synchronously. The second elastic slide bar 262 slides into the working chamber 261 and drives the rack 263 to move synchronously, and the rack 263 drives the driving gear 265 to rotate, and the driving gear 265 drives the driving screw 264 to rotate synchronously. Since the driving screw 264 is threadedly connected to the connecting shaft 23 and the connecting shaft 23 is also vertically slidably installed on the upper end of the movable base 21, when the driving screw 264 rotates, the connecting shaft 23 on the rear side also moves downward synchronously and drives the mounting seat and the top roller 268 to move The top roller 268 moves downward, so that the top roller 268 is pressed on the top of the horizontal square material. In this way, downward elastic pressure is applied to the horizontal square material to prevent it from tilting during transportation, thereby ensuring the contact between the horizontal square material and the roller 12; the movable bases 21 on the front and rear sides continue to move relative to each other, so that the contact cylinder 24 centers the horizontal square material. At this time, the top roller 268 also gives a certain pressure to the horizontal square material. After completion, there is no need to immediately reset the movable bases 21 on the front and rear sides. At this time, the front and rear end and the upper and lower ends of the horizontal square material are limited. In this way, the square material can stably enter the next sawing process, which can ensure the sawing effect and there is no need to set an additional drive to press the top of the horizontal square material before the next sawing.

[0043] In addition, see Figure 8-9 In order to prevent the bottom push rod 232 from contacting the bidirectional screw 222 when rotating downward, and to prevent the bottom push rod 232 from blocking the first elastic slide bar 236 from docking with the second elastic slide bar 262 when rotating downward, the position of the bottom push rod 232 can be made not to be on the same vertical plane as the bidirectional screw 222 and the first elastic slide bar 236. In this way, the bottom push rod 232 will not contact the bidirectional screw 222 or the first elastic slide bar 236 no matter how it rotates downward. The improvement here will not affect the locking state and the rotatable state of the bottom push rod 232 and will not be elaborated.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
