Description

Technical Field

[0001] The invention relates to the field of furniture board conveying and positioning, and in particular to a conveying and positioning device for furniture board production. Background Art

[0002] During the processing of furniture panels, the panels will be punched while being transported on the production line. When punching the panels, a relevant positioning device is required to position the panels below the punching device. Usually, the punching device is a gantry type, and the punching device is installed on the gantry. The gantry is located above the panel conveyor line. After the panel is positioned below the gantry through the positioning device, the gantry drives the punching device to move horizontally or vertically through the motor, lead screw, guide rail and other transmission components according to the pre-set program, so that the drill bit is aligned with the position where the hole needs to be drilled on the furniture panel. After the drilling is completed, the drill bit rises and resets, and the gantry moves to the next drilling position or waits for the next panel to be transported to drill the hole; When the existing furniture boards are positioned on the conveyor, they are mostly blocked and positioned by baffles, and then the furniture boards are directly pressed against the conveyor rollers by cylinders before drilling. Since the boards are located on the rollers, the boards are prone to movement during drilling, resulting in deviations in the online drilling of the boards. In addition, during the drilling process, after the drilling drill is fully inserted into the board, the conveyor rollers below the board are damaged. Summary of the invention

[0017] 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.

[0018] The present invention provides Figure 1-Figure 10 A conveying and positioning device for furniture board production shown in the figure comprises a conveyor 1, a controller 2 is installed on one side of the frame of the conveyor 1, and a front fixing frame 4 and a rear fixing frame 5 are fixed in sequence on the bottom of the frame of the conveyor 1 in the direction toward its output port; The interior of the front fixed frame 4 is connected to two slides 7 through a driving assembly, and four support blocks 8 are fixed on the top of the slide 7. A fixed box 9 is fixed on the top of each of the four support blocks 8. The fixed box 9 is located between two adjacent conveying rollers of the conveyor 1. A positioning mechanism for clamping and positioning the furniture board is provided on the fixed box 9. According to the actual length of the furniture board, four or more support blocks 8, fixed boxes 9 and the positioning mechanisms thereon can be added to meet actual needs. In this application, two slides 7 with a total of eight support blocks 8 and eight positioning mechanisms are used to demonstrate the principle; A trigger mechanism for triggering the positioning mechanism to operate is arranged inside the rear fixing frame 5 .

[0019] Furthermore, the driving assembly includes a motor 6, which is installed on one side of the front fixed frame 4. A lower bidirectional screw rod 26 is connected to the motor shaft of the motor 6. The lower bidirectional screw rod 26 is threadedly connected to two slide plates 7. The two slide plates 7 are respectively located on both sides of the lower bidirectional screw rod 26, and the slide plates 7 are slidably connected to the front fixed frame 4 through a slide rail. The motor 6 is electrically connected to the controller 2. The motor 6 adopts a forward and reverse motor. The rotation direction and number of turns of the lower bidirectional screw rod 26 are controlled by the controller 2, so that the two slide plates 7 can move toward or away from each other, and then the distance between the two slide plates 7 can be adjusted so that the subsequent positioning mechanism can position the furniture plate.

[0020] Further, the positioning mechanism includes a side clamping assembly and an upper and lower clamping assembly; The side clamping assembly includes a connecting frame 18 and a rectangular hole. The rectangular hole is opened on the outer wall of the fixed box 9. One side of the connecting frame 18 passes through the rectangular hole and extends to the inside of the fixed box 9. The other side of the connecting frame 18 is located outside the fixed box 9. A guide wheel 19 for contacting the furniture board is vertically fixed inside the connecting frame 18. A guide rod 23 is fixed on the side of the connecting frame 18 facing the inside of the fixed box 9. The end of the guide rod 23 penetrates the fixed box 9, and a limiting disk 22 is fixed to the end of the guide rod 23. The outside of the guide rod 23 is located between the fixed box 9 and the connecting frame 18 and is sleeved with a first spring 24. The first spring 24 and the guide rod 23 can make the connecting frame 18 always maintain a tendency to move to the outside of the fixed box 9, thereby ensuring that after the guide wheel 19 contacts the furniture board, the board can be limited from the side without affecting the conveying operation of the board. The outer wall of the fixing box 9 is located outside the rectangular hole and fixed with an anti-skid pad 17, which is made of rubber or other colloid materials and mainly plays an anti-skid role when clamping the furniture board; The width of the rectangular hole is greater than the diameter of the guide wheel 19, so that during the process of the guide wheel 19 squeezing the furniture board, the guide wheel 19 is eventually retracted into the fixed box 9, and the anti-slip pad 17 replaces the guide wheel 19 to contact the furniture board and squeeze the board.

[0021] Furthermore, the upper and lower clamping assemblies include a vertically arranged fixed rod 10 and an upper bidirectional screw rod 11, both of which penetrate the fixed box 9, and the fixed rod 10 is welded and fixed to the fixed box 9, and the upper bidirectional screw rod 11 is rotatably connected to the fixed box 9 through a bearing, and the middle part of the upper bidirectional screw rod 11 does not contain threads, so it can be rotatably connected to the fixed box 9 by means of a bearing, and a vertical plate 20 is fixed to one side of the inner side of the connecting frame 18, and two vertical plates 20 are fixed to one side of the vertical plate 20 close to the upper bidirectional screw rod 11. Tooth plate 21, a gear 25 is fixed on the outside of the upper bidirectional screw rod 11 near the tooth plate 21, the gear 25 is meshed with the tooth plate 21, and the top and bottom ends of the fixed rod 10 and the upper bidirectional screw rod 11 are fixed with end plates 27, and connecting plates 12 are arranged above and below the fixed box 9, the fixed rod 10 passes through the connecting plate 12, the connecting plate 12 is threadedly connected to the upper bidirectional screw rod 11, one side of the connecting plate 12 is connected to a fixing plate 13, and one side of the fixing plate 13 is installed through a locking piece with a pressing plate 14 for pressing the furniture board.

[0022] Furthermore, the locking member includes two fixing bolts 16 and two strip holes 15. The two strip holes 15 are vertically opened inside the pressure plate 14. The two fixing bolts 16 pass through the two strip holes 15 and are threadedly connected to the fixing plate 13. The fixing bolts 16 can be replaced with bolts and nuts, as shown in the attached manual. Figure 5As shown, the relative position of the pressing plate 14 and the fixing plate 13 is adjusted through the strip hole 15. After being locked by the fixing bolt 16, the gap between the upper and lower pressing plates 14 can be changed to avoid excessive squeezing force of the pressing plate 14 on the furniture board. At the same time, the device can also clamp boards of different thicknesses.

[0023] Furthermore, the trigger mechanism includes a rear fixed frame 5, a limiting plate 28 is fixed to the inner top of the rear fixed frame 5, and a top plate 31 is arranged inside the rear fixed frame 5, the top of the top plate 31 passes through the limiting plate 28, and the inner bottom of the rear fixed frame 5 is located on both sides of the limiting plate 28 and is slidably connected with a top block 32 through a slide groove, and the two top blocks 32 are respectively connected to the two slide plates 7, and one side of the top block 32 and the side of the top plate 31 close to the top block 32 are both inclined. The inclined parts of the top block 32 and the top plate 31 can refer to the attached manual. Figure 7 When the two top blocks 32 move toward the middle of the top plate 31, the top plate 31 will be forced to move upward. When the bottom of the top plate 31 is flush with the top of the top blocks 32, it means that the height of the top plate 31 has risen to the highest. Even if the two top blocks 32 move toward each other again, the height of the top plate 31 will not change, thereby preventing the top plate 31 from rising too high and affecting the drilling operation. A back plate 29 is fixed on the top of the top plate 31 , one side of the back plate 29 is connected to a movable plate 30 via a resilient member, and a through hole 36 is opened in the middle of the back plate 29 , a pressure touch switch 37 is installed inside the through hole 36 , and a pressure contact head of the pressure touch switch 37 is close to the movable plate 30 .

[0024] Furthermore, the rebound member includes four cylindrical holes 39, which are respectively opened at four corners of the back plate 29, and the cylindrical holes 39 are provided with a third spring 42, and a slidable top plate 41 is provided inside the cylindrical hole 39 on one side of the third spring 42, and a plug plate 38 is connected to the other side of the third spring 42 through a thread inside the cylindrical hole 39, and a top rod 40 is connected to one side of the top plate 41, and the end of the top rod 40 passes through the back plate 29, and the end of the top rod 40 is connected to the movable plate 30. When the furniture board is connected with the back plate 29, the back plate 29 is connected to the movable plate 30. After the movable plate 30 is contacted and squeezed, the movable plate 30 will touch the pressure switch 37, and then the positioning operation of the furniture plate will be performed again. When the positioning operation is completed, during the resetting process of the slide plate 7, the top block 32, the top plate 31 and the movable plate 30 will also be reset. The second spring 35 and the baffle 34 can make the limit rod 33 always pull the top plate 31 downward, thereby improving the convenience of the resetting process of the top plate 31. In conjunction with the third spring 42, the top plate 41 and the top rod 40, the movable plate 30 can rebound quickly when not squeezed.

[0025] Specifically, a limiting rod 33 is fixed at the bottom end of the top plate 31 , the limiting rod 33 passes through the rear fixing frame 5 , and a baffle 34 is fixed to the bottom end of the limiting rod 33 , and a second spring 35 is sleeved on the outside of the limiting rod 33 between the rear fixing frame 5 and the baffle 34 .

[0026] Specifically, guide plates 3 are fixed on both sides of the top of the conveyor 1, and an obstacle sensor 43 for monitoring the entry of furniture panels into the positioning mechanism station is installed on one of the guide plates 3.

[0027] The overall principle of the above scheme is as follows: When in use, place the furniture board on the top of the conveyor 1, then start the conveyor 1 through the controller 2, and move the furniture board toward the output port of the conveyor 1 (see the attached manual). Figure 1 and instructions attached Figure 2 As the plate moves, it will enter the "positioning mechanism" station. When the plate enters half of the "positioning mechanism" station, it will be captured by the obstacle sensor 43. At this time, the controller 2 will start the motor 6, and then the motor 6 will drive the lower bidirectional screw 26 to rotate, so that the two slides 7 move toward each other, and then drive the fixed boxes 9 on both sides of the furniture board to move toward each other synchronously (this moving distance can be set in advance according to the actual length of the board by the number of rotations of the motor 6. For example, when the board length is 1.2 meters, after the obstacle sensor 43 detects that the board will enter the "positioning mechanism" position, the distance between the two fixed boxes 9 after moving toward each other is ensured to be greater than 1.2 meters, thereby ensuring that the guide wheel 19 does not enter the fixed box 9, so as to limit the two sides of the furniture board while stably allowing the conveyor 1 to transport the board); When the two slide plates 7 move toward each other, they will also synchronously drive the two top blocks 32 to move toward the middle of the top plate 31, thereby forcibly pushing the top plate 31 to move upward. After the top plate 31 moves upward, the back plate 29 and the movable plate 30 will be lifted (the back plate 29 and the movable plate 30 are initially located below the conveying roller of the conveyor 1, and after lifting, the back plate 29 and the movable plate 30 will be higher than the conveying roller of the conveyor 1), thereby blocking the output port of the conveyor 1. As the conveyor 1 continues to transport, the furniture plate on the conveyor 1 will eventually squeeze the movable plate 30. After the movable plate 30 is squeezed, the movable plate 30 will touch the pressure switch 37. At this time, the controller 2 will stop the conveying operation of the conveyor 1 (at this time, it means that the furniture plate has reached the designated "punching" station, so that the punching device can punch holes in the plate online. The punching device does not belong to the technology to be protected by the present invention); After the conveyor 1 stops conveying, the controller 2 will start the motor 6 again, continue to make the two slides 7 move towards each other, and then make the fixed boxes 9 on both sides of the furniture board move towards the board again. When the distance between the two fixed boxes 9 is just the same as the width of the board, the motor 6 will stop working. At this time, the guide wheel 19 is completely retracted into the fixed box 9, and the anti-slip pad 17 is in contact and squeezed with the board. In the process of the guide wheel 19 being retracted into the fixed box 9, the connecting frame 18 will also enter the fixed box 9. When the connecting frame 18 gradually enters the fixed box 9, the tooth plate 21 will drive the gear 25 to rotate, and then drive the upper bidirectional screw rod 11 to rotate. In cooperation with the fixing rod 10, the upper and lower connecting plates 12 and the fixed plate 13 can be moved towards each other as a whole, so that the upper and lower pressing plates 14 can squeeze the furniture board. Since the upper and lower pressing plates 14 can only move synchronously, the height of the furniture board will eventually be squeezed at the middle height of the guide wheel 19, so that the furniture board can be suspended, so as to avoid damage to the conveying rollers of the conveyor 1 during the subsequent furniture board punching operation; At this point, the furniture board has completed the "suspended" positioning on the conveyor 1; After the plate is positioned and punched, the motor 6 will reset the two slide plates 7 through the lower bidirectional screw rod 26 to position the furniture plate to be processed later.

[0028] The above description is only by way of illustration of certain exemplary embodiments of the present invention. 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.
