Description

Technical Field

[0001] The invention belongs to an automatic material conveying device, and in particular, relates to a plywood veneer gluing conveying device. Background Art

[0002] Plywood is one of the commonly used materials for furniture and one of the three major types of man-made boards. It is widely used in many fields such as construction, furniture manufacturing, and packaging. With the development of these industries, the output and quality requirements of plywood are constantly increasing, and efficient and stable gluing and conveying devices are needed to meet large-scale production needs. In the production process of plywood, gluing is a key process in plywood production. The quality of gluing directly affects the bonding strength and overall quality of plywood. The gluing and conveying device can accurately and smoothly convey the plywood to the gluing position to ensure the uniformity and stability of the gluing.

[0003] A Chinese patent with publication number "CN104477594B" discloses an automatic veneer gluing conveying device for plywood, comprising a material preparation and shaping conveying mechanism for moisture content detection, an automatic material pile lifting platform, an automatic veneer conveying mechanism and a foldable directional conveying mechanism. The automatic veneer conveying mechanism is provided with a reverse separation limiting mechanism, which limits the veneer pile after the first veneer is separated. The automatic veneer pile magazine recovery mechanism cooperates with the foldable directional conveying mechanism to recover wood chips and impurities in the veneer pile. The device improves the veneer gluing quality and increases labor production efficiency.

[0004] During the later use, the device still has the following problems: 1. The thickness of plywood veneer is usually between 0.4-10 mm. The veneer is large in area and thin in thickness. When it is taken out from the pile and placed in the foldable directional conveying mechanism, the veneer is taken out by rotating the veneer automatic conveying mechanism, which can easily cause damage to the veneer; 2. Due to the thin thickness of the veneer, the separation effect of the reverse separation limiting mechanism is not ideal.

DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, a plywood veneer gluing and conveying device includes a frame 1, the frame 1 includes a base plate 101, a swivel seat 101A is fixedly connected to the rear of the base plate 101, and a lifting component 2 is provided on the base plate 101. By setting the lifting component 2, the pile of plates 3 is gradually pushed upward, and the grabbing component 4 and the carrying component 6 are cooperated to take the top layer of veneer from the pile and place it on the transport platform 5 to continue to be transported downward to the gluing operation site, so that the destacking operation is automatically completed, which reduces the labor intensity of the workers. A side plate 102 is fixedly connected to the top of the bottom plate 101, a slide groove 102A is fixedly provided at the bottom end of the side plate 102, a limiting groove 102B is fixedly provided on the inner wall of the side plate 102, and a tooth group 102C is fixedly provided on the limiting groove 102B. When the tooth group 102C cooperates with the anti-retraction component 209, the lifting component 2 is prevented from moving downward, thereby avoiding the accidental fall of the lifting component 2, and improving the stability of the board 3 pile on the lifting platform 208. When the tooth group 102C is out of contact with the anti-retraction component 209, the lifting component 2 can move up and down at will; a grabbing component 4 is fixedly connected to the top of the side plate 102. By setting the grabbing component 4, one end of the top veneer can be lifted in cooperation with the conveying component 6, so that the conveying component 6 can smoothly separate the veneer from the pile, and the separated veneer is blown and washed to clean the wood residue and impurities on the surface of the veneer, so as to smoothly complete the subsequent gluing operation.

[0018] A transport platform 5 is fixedly provided on one side of the frame 1, and a plurality of transport transfer tubes 501 are rotatably connected to the transport platform 5. After the single board is placed on the transport platform 5, the plurality of transport transfer tubes 501 rotate to continue to transport the board 3. A conveying assembly 6 is provided on the transport platform 5. By providing the conveying assembly 6, the single board is separated from the board 3 by airflow and carried out to the transport platform 5, avoiding the traditional method of directly dragging the single board to the transport platform 5, which causes the board 3 to be damaged. The single board is thin and has a large area, and forced dragging is easy to damage the single board due to the friction between the boards 3. The transport component 6 includes a hydraulic push rod 601, a guide plate 603 and a transport frame 604. The hydraulic push rod 601 is fixedly connected to the transport platform 5. The extension rod of the hydraulic push rod 601 is fixedly connected to the push plate 602. The guide plate 603 is fixedly connected to the transport platform 5. The push plate 602 cooperates with the guide plate 603. A centering fixing component 7 is provided on the transport frame 604. By setting the centering fixing component 7, the single board is centered on the transport frame 604 to facilitate subsequent gluing operations. At the same time, after the single board is centered, it can be fixed to cooperate with the air outlet 405 to blow out strong wind to clean the wood residue on the surface of the single board, so as to avoid a large displacement of the single board position during the blowing process.

[0019] like Figure 4 and Figure 6As shown, the lifting assembly 2 includes a driving motor 201 and a lifting platform 208. The driving motor 201 is fixedly connected to the outer wall of the frame 1. The output shaft of the driving motor 201 is fixedly connected to a screw rod 202. The screw rod 202 is rotatably connected to the frame 1. A connecting block 203 is meshedly connected to the screw rod 202. A push rod 204 is fixedly connected to the bottom of the connecting block 203. A connecting rod 1 205 is rotatably connected to the push rod 204. Both ends of the push rod 204 are slidably connected to the slide groove 102A. A connecting rod 206 is rotatably connected to the middle of the connecting rod 1 205. The lower end of the connecting rod 206 is rotatably connected to the slide groove 102A. The rotating seat 101A is rotatably connected, and the upper end of the connecting rod 206 is rotatably connected with the sliding seat 207, and the sliding seat 207 is slidably connected to the bottom of the lifting platform 208. After the staff places the pile of plates 3 on the lifting platform 208, the driving motor 201 drives the screw 202 to rotate, and the screw 202 drives the connecting block 203 and the push rod 204 to rotate, and drives the scissor-type lifting mechanism to rise upward, so that the plates 3 on the top layer contact the grabbing assembly 4. As the plates 3 on the top layer are continuously taken out, the lifting platform 208 continues to rise until all the piles of plates 3 are transported. The side wall of the lifting platform 208 extends outward with a protrusion 208A, and the protrusion 208A is slidably connected to the limiting groove 102B. The sliding connection between the protrusion 208A and the limiting groove 102B can improve the stability of the lifting platform 208 and prevent the lifting platform 208 from tilting.

[0020] A swivel seat 208B is fixedly connected to the bottom of the lifting platform 208, and the swivel seat 208B is rotatably connected to the upper end of the connecting rod 1 205. A slide groove 208C is fixedly provided in the protrusion 208A, and a blocking piece 208D is fixedly provided at the bottom of the slide groove 208C. A stop assembly 209 is provided on the slide groove 208C. By setting the stop assembly 209, when the lifting platform 208 moves upward, the block 209G is squeezed by the tooth group 102C and overcomes the elastic force of the second compression spring 209F to retract into the cavity 209E. When the lifting platform 208 tends to move downward, the block 209G clamps the tooth group 102C to prevent the lifting platform 208 from moving downward, thereby avoiding a large tilt of the plate 3 pile on the lifting platform 208 and improving the stability of the plate 3 when being transported upward.

[0021] like Figure 5 and Figure 7As shown, the backstop assembly 209 includes a pressure rod 209A, a pressure spring 209B is fixedly provided inside the pressure rod 209A, the other end of the pressure spring 209B is fixedly connected to the baffle 208D, the pressure rod 209A is vertically slidably connected to the second slide groove 208C, the top of the pressure rod 209A is rotatably connected to a connecting rod 209C, the other end of the connecting rod 209C is rotatably connected to a slide rod 209D, the slide rod 209D is horizontally slidably connected to the second slide groove 208C, a cavity 209E is fixedly provided at the outer end of the slide rod 209D, a pressure spring 209F is fixedly connected to the inner wall of the bottom of the cavity 209E, a block 209G is fixedly connected to the other end of the pressure spring 209F, the block 209G is slidably connected to the cavity 209E, and the block 209G cooperates with the tooth group 102C. When the pile of plates 3 is placed on the lifting platform 208, the pressure rod 209A moves downward under pressure, pushing the slide bar 209D outward, so that the block 209G contacts the tooth group 102C. At this time, the backstop assembly 209 only allows the lifting platform 208 to move upward. When all the plates 3 are moved from the lifting platform 208, the pressure rod 209A is pushed by the compression spring 209B to tilt upward and pull the slide bar 209D inward, so that the block 209G is completely separated from the tooth group 102C. At this time, the lifting platform 208 can move up and down at will.

[0022] like Figure 8As shown, the grabbing assembly 4 includes a support frame 401, which is fixedly connected to the top of the side plate 102, and a compression spring 401A is fixedly connected to the inner wall of the upper part of the support frame 401. The other end of the compression spring 401A is fixedly connected to a slide plate 402, and the slide plate 402 is slidably connected to the support frame 401. Extrusion columns 402A are fixedly provided at both ends of the slide plate 402. A negative pressure suction nozzle 403 is slidably connected to the middle part of the slide plate 402. The top of the negative pressure suction nozzle 403 is connected to the vacuum device through an air pipe. When the vibration device is started, the negative pressure suction nozzle 403 can generate suction to The single board is sucked, and the vacuum equipment is a prior art and can be purchased directly, so it will not be repeated here; a compression spring four 404 is fixedly connected to the negative pressure suction nozzle 403, and the top of the compression spring four 404 is fixedly connected to the slide plate 402, and the elastic coefficient of the compression spring three 401A is greater than the elastic coefficient of the compression spring four 404, and an air outlet pipe 405 is also fixedly connected to the top side wall of the support frame 401, and the top of the air outlet pipe 405 is connected to the hair dryer through an air pipe. When the hair dryer is started, clean air can be blown out from the air outlet pipe 405 at a high speed. The hair dryer is a prior art and can be purchased directly, so it will not be repeated here. Driven by the compression spring 401A, the slide plate 402 moves downward, driving the negative pressure suction nozzle 403 to contact the single board and adsorb it. As the slide plate 402 is squeezed upward, the slide plate 402 and the negative pressure suction nozzle 403 drive one end of the single board to tilt upward and separate from the pile of plates 3. When the conveying component 6 moves backward and completely separates the single board from the pile of plates 3, the negative pressure suction nozzle 403 stops operating, and the single board falls completely on the conveying rack 604. After being centered and fixed, the air outlet pipe 405 blows out strong wind to clean the impurities on the surface of the plate 3.

[0023] like Fig. 9 , Fig.10 and Fig.11 As shown, a pressing plate 602B is fixed on the top of the push plate 602, and the pressing plate 602B cooperates with the pressing column 402A. The middle part of the pressing plate 602B bulges upward. When the bulge in the middle contacts the pressing column 402A, the pressing plate 602B presses the slide plate 402 upward, and the slide plate 402 drives the negative pressure suction nozzle 403 to lift one end of the single board upward. The front end and the rear end of the pressing plate 602B are both concave parts with relatively low height. When the concave part contacts the pressing column 402A, the pressing plate 602B presses the slide plate 402 upward. When the slide plate 402 is pushed by the compression spring 401A, it moves downward, and the slide plate 402 drives the negative pressure suction nozzle 403 and the blowing pipe to approach the single board; an extrusion pushing groove 602A is fixedly provided on the push plate 602, and the inner wall of the push plate 602 is slidably matched with the guide plate 603, and a fixed extrusion block 603B and a sensor 603A are fixedly connected to the inner wall of the guide plate 603, and a guide groove 603C is fixedly provided on the guide plate 603, and the guide groove 603C cooperates with the extrusion pushing groove 602A.

[0024] The extrusion push groove 602A includes a transverse groove and an oblique groove, the oblique groove is located at the rear end of the transverse groove, and the guide groove 603C includes a horizontal groove and a vertical groove, the vertical groove is located at the front end of the horizontal groove. When the hydraulic push rod 601 extends and drives the push plate 602 to move backward, the transverse groove contacts the limiting column 604A of the transport rack 604, driving the limiting column 604A to contact the horizontal groove and slide back and forth along the horizontal groove, thereby driving the transport rack 604 to slide back and forth. When the hydraulic push rod 601 retracts and drives the push plate 602 to move forward to the front end, the limiting column 604A contacts the area of ​​the vertical groove. At this time, the transport rack 604 moves forward to the front end. As the hydraulic push rod 601 continues to contract, the push plate 602 continues to move forward. At this time, the oblique groove contacts the limiting column 604A, driving the limiting column 604A to move up and down in the vertical groove. The transport rack 604 is lowered to the bottom of the transport transfer tube 501, and the single board is placed on the transport platform 5 and continues to be transported backward.

[0025] like Fig.12 and Fig.16 As shown, the outer wall of the transport rack 604 is fixedly connected to the limit column 604A, the guide groove 603C and the extrusion push groove 602A are both slidably matched with the limit column 604A, and the rear part of the transport rack 604 is fixedly provided with an air floating lifting plate 604B, which is connected to a blowing device through an air pipe. When the blowing device is started, the air floating lifting plate 604B can spray gas outward; the outer wall of the transport rack 604 is fixedly provided with a slot 604C, and the interior of the transport rack 604 is fixedly connected with multiple groups of slot plates 604D, and the bottom of the slot plate 604D is fixedly provided with a slot 604E. After one end of the single board is lifted by the negative pressure suction nozzle 403, the transport rack 604 moves backward, and the air floating lifting plate 604B enters from the lifted opening. Since the air floating lifting plate 604B is provided with an air duct, the single board can be gradually lifted by air flow to avoid the contact and friction between the single board and the air floating lifting plate 604B, which may cause damage to the single board. Therefore, the transport rack 604 moves backward, and finally the single board is placed on the transport rack 604. During this process, the single board does not slide relative to the pile of plates 3, so the breakage rate of the single board can be reduced.

[0026] like Fig.13 , Fig.14 and Fig.15As shown, the center fixed component 7 includes a push frame 701, which is slidably connected to the slot 604C, and the push frame 701 cooperates with the fixed extrusion block 603B. A compression spring 5 705 is fixedly connected to the inner side of the push frame 701, and the other end of the compression spring 5 705 is fixedly connected to an extrusion slider 704. The extrusion slider 704 is slidably connected to the inside of the slot plate 604D, and a pressure claw 703 is vertically slidably connected to the extrusion slider 704. The bottom of the pressure claw 703 is rotatably connected to a connecting rod 2 702, and the other end of the connecting rod 2 702 is rotatably connected to the bottom of the inner side of the push frame 701. The center fixing component 7 moves backward with the transport frame 604. When the fixed squeezing block 603B contacts the pushing frame 701, the pushing frame 701 is pushed inward, driving the squeezing slider 704 to approach and contact the side wall of the single board, so that the position of the single board is adjusted to the center position. As the pushing frame 701 continues to be squeezed inward, the squeezing slider 704 can no longer move, and the compression spring five 705 is compressed and contracted. The pressing claw 703 moves downward under the drive of the connecting rod two 702, exerting downward pressure on the top of the single board, firmly fixing the single board on the transport frame 604, and cooperating with the air outlet duct 405 to clean the impurities on the surface of the single board.

[0027] Working principle: 1. The plate 3 material pile is carried to the lifting platform 208 by the worker. The plate 3 presses the pressure rod 209A, and the anti-retraction component 209 contacts the gear group 102C to prevent the lifting platform 208 from retreating, allowing only the lifting platform 208 to rise. The drive motor 201 is started, and the lifting mechanism pushes the plate 3 material pile upward; 2. If Fig.17 As shown, when the top of the plate 3 reaches a certain height, the sensor 603A senses the plate 3, controls the driving motor 201 to stop rotating, and the lifting mechanism stops rising. At this time, the plate 3 at the top contacts the negative pressure suction nozzle 403, and the negative pressure suction nozzle 403 starts to work and sucks the plate 3; 3. The hydraulic push rod 601 extends, and the push plate 602 moves forward. In the initial period of time, the limit column 604A drives the transport frame 604 to move upward, and the transport frame 604 gradually becomes higher than the transport platform 5. Then, the limit column 604A drives the transport frame 604 to move backward, and the squeezing plate 602B squeezes the squeezing column part 402A upward, the slide plate 402 rises, and the negative pressure suction nozzle 403 drives one side of the plate 3 to lift upward, and this part of the plate 3 leaves the material pile; 4. The air flotation lifting plate 604B ejects gas outwards. As the transport rack 604 moves forward, the rear of the sheet 3 gradually separates from the pile and eventually leaves the pile. The transport rack 604 is inserted under the veneer. The negative pressure suction nozzle 403 is closed and the veneer falls onto the transport rack 604. 5. The hydraulic push rod 601 continues to extend, and the transport rack 604 continues to move forward. When the push rack 701 contacts the fixed squeeze block 603B, the push rack 701 pushes the squeeze slider 704 inward, and the squeeze slider 704 adjusts the plate 3 to the center. The push rack 701 continues to move inward, and the pressure claw 703 presses down to firmly fix the single board in the transport rack 604. At this time, the hydraulic push rod 601 stops moving, and the air outlet pipe 405 is started to blow and clean the surface of the single board; 6. If Fig.18 and Fig.19 As shown, the air outlet 405 is closed, the hydraulic push rod 601 is retracted, the pressing claw 703 rises, and the slide plate 402 is pressed against the side wall of the plate 3. The transport rack 604 carries the single board and moves forward to the upper part of the transport platform 5. The hydraulic push rod 601 continues to be retracted, and the transport rack 604 descends until it is lower than the transport transfer tube 501. At this time, the single board is on the transport transfer tube 501 and is transported backward; 7. When all the plates 3 on the lifting platform 208 are moved away, the pressure rod 209A is lifted upward under the push of the compression spring 209B, pulling the slide bar 209D away from the tooth group 102C, and the backstop assembly 209 allows the lifting platform 208 to descend, and the lifting assembly 2 gradually returns to the bottom of the frame 1.
