Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly relates to a carton sealer with self - adaptive deviation correction. Background Art

[0002] Carton sealers are mainly applicable to the carton sealing and packaging. They can operate independently or be used in conjunction with an assembly line. They can operate on a single carton or be used in combination with equipment such as carton forming and opening machines, carton packing machines, labeling machines, strapping machines, pallet stacking machines, conveyors, etc. to form a packaging assembly line. They are essential equipment for packaging assembly line operations. Carton sealers are mainly divided into: automatic lid - opening and sealing machine series, pneumatic adjustment sealing machine series, automatic sealing machine series, corner - type sealing machine series, four - corner side - sealing machines, I - shaped sealing machines, etc. The sealing methods can be divided into: up - and - down drive, left - and - right drive, side - side, corner - side, etc. Generally, transparent tape and kraft paper materials are used.

[0003] Before sealing the carton, the existing carton sealer needs to correct the position of the carton. Usually, two centering beams that can move horizontally in opposite directions are used as deviation - correction mechanisms to correct the orientation of the carton. However, this kind of deviation - correction mechanism will cause rigid contact between the carton and the centering beam, which will lead to damage to the side of the carton due to extrusion. At the same time, when the carton rotates, its bottom will be worn. For this reason, a carton sealer with self - adaptive deviation correction is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the existing carton sealer usually uses two centering beams that can move horizontally in opposite directions as deviation - correction mechanisms to correct the orientation of the carton before sealing. However, this kind of deviation - correction mechanism will cause rigid contact between the carton and the centering beam, which will lead to damage to the side of the carton due to extrusion. At the same time, when the carton rotates, its bottom will be worn. The present invention provides a carton sealer with self - adaptive deviation correction.

[0005] The present invention specifically adopts the following technical solutions to achieve the above - mentioned purpose: A carton sealer with self - adaptive deviation correction includes a conveyor. An electric lifting frame is arranged on the top of the conveyor. A sealing mechanism body is fixedly installed on the top of the electric lifting frame. A sealing table is fixedly installed inside the conveyor. A first assembly hole is opened on the top of the sealing table. A first electric lifting table is fixedly installed inside the first assembly hole. The telescopic end of the first electric lifting table faces vertically upward and is fixedly installed with an electric turntable. Two suspension frames are fixedly installed on both sides of the conveyor. A vertically - arranged first electric push rod is fixedly installed on the top of each suspension frame. The telescopic ends of two first electric push rods on the same side are fixedly installed with the same correction beam. The two correction beams are symmetrically arranged and are both slidably installed on the top of the sealing table. Support tables are arranged on both sides of the conveyor. A deviation - correction mechanism for correcting the deviation of the carton is arranged on the top of each support table.

[0006] Furthermore, the deviation rectifying mechanism includes an electric lifting rod arranged on the top of the support table. The telescopic end of the electric lifting rod faces vertically upward and is fixedly installed with a lifting carriage. Two horizontally arranged horizontal sliding rods are slidably installed on the lifting carriage. The same deviation rectifying beam is fixedly installed between the two horizontal sliding rods on the same side. Horizontally arranged second electric push rods are fixedly installed inside the lifting carriage. The telescopic ends of the second electric push rods at the same position are fixedly installed on the side wall of the deviation rectifying beam. The two deviation rectifying beams are symmetrically arranged on the top of the conveyor.

[0007] Furthermore, deviation rectifying belts are fixedly installed inside the deviation rectifying beams. A plurality of uniformly distributed hanging strips are fixedly installed on the side walls of the deviation rectifying belts.

[0008] Furthermore, linear guide rails are fixedly installed on the top of the support table. Electric sliders are drivingly installed on the linear guide rails. The two electric lifting rods are respectively fixedly installed on the tops of the two electric sliders.

[0009] Furthermore, height measuring frames are fixedly installed on the tops of the two horizontal sliding rods located above. The two height measuring frames are symmetrically distributed and are respectively located on the tops of the two deviation rectifying beams.

[0010] Furthermore, a deviation rectifying table is fixedly installed inside the conveyor. A second assembly hole is formed inside the deviation rectifying table. A second electric lifting table is fixedly installed inside the second assembly hole. A deviation rectifying turntable is rotatably installed on the top of the second electric lifting table.

[0011] Furthermore, a measuring gantry is fixedly installed at one end of the conveyor away from the electric lifting frame. A first ultrasonic measuring instrument is fixedly installed on the top of the measuring gantry. Oblique frames are fixedly installed on both sides of the top of the measuring gantry. Second ultrasonic measuring instruments are fixedly installed on one side of each oblique frame. The first ultrasonic measuring instrument and the second ultrasonic measuring instruments both face the conveyor.

[0012] Furthermore, blanking conveyor belts are fixedly installed inside the calibration beams.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention is provided with a deviation rectifying conveyor belt. When the deviation rectifying beam moves towards the carton, the deviation rectifying conveyor belts on both sides will rotate slowly in the reverse direction, so that the hanging strips on the side of the deviation rectifying conveyor belt are stuck on the side of the carton, and then drive the carton to rotate back to the correct position. The deviation rectifying conveyor belt stops rotating, and the deviation rectifying beams on both sides drive the stationary deviation rectifying conveyor belt to clamp and limit the carton, completing the deviation rectification of the carton. By driving the carton to pre-rotate through the deviation rectifying conveyor belt rotating in the reverse direction, direct rigid contact between the deviation rectifying beams on both sides and the side of the carton is avoided, preventing the problem of damage to the side of the carton; 2. The present invention is provided with electric sliders and linear guide rails. After the carton is aligned and clamped and limited by the deviation rectifying beams, the electric sliders on both sides will drive the electric lifting rods to drive the deviation rectifying beams at the top to move along the linear guide rails, so that the carton is conveyed to the bottom of the sealing mechanism body while being limited. When the carton is sent to the first electric lifting table, the deviation rectifying mechanism releases and resets the carton, and the calibration beams on both sides will take over the deviation rectifying beams to limit the carton, preventing the carton from shifting again during the subsequent conveying process after being deviation rectified; 3. The present invention is provided with a second electric lifting table. After the carton is conveyed to the top of the deviation rectifying table by the conveyor, the second electric lifting table inside the second assembly hole will drive the deviation rectifying turntable to lift upward and lift the carton for a short distance. Then, when the deviation rectifying mechanism corrects the carton, the carton will rotate. The deviation rectifying turntable separates the bottom of the carton from the second electric lifting table and the deviation rectifying table, enabling the carton to rotate smoothly without causing bottom wear; 4. The present invention is provided with a first ultrasonic measuring instrument and a second ultrasonic measuring instrument. When the carton is sent to one end of the conveyor, the carton will pass through the measuring gantry, and then be scanned by the first ultrasonic measuring instrument directly above and the second ultrasonic measuring instruments obliquely above on both sides, so as to detect the external shape structure of the carton, obtain approximate data of the current length, width, height and orientation of the carton, and provide a reference for the subsequent position adjustment of the sealing mechanism body and the operation of the deviation rectifying mechanism.

[0019] Such as Figures 1 to 8As shown, an automatic box sealing machine with adaptive deviation correction includes a conveyor 1. As Figure 1 shown, an electric lifting frame 2 is arranged on the top of the conveyor 1, and a box sealing mechanism body 3 is fixedly installed on the top of the electric lifting frame 2. As Figure 3 shown, a box sealing table 4 is fixedly installed inside the conveyor 1. A first assembly hole is opened on the top of the box sealing table 4, and a first electric lifting table 5 is fixedly installed inside the first assembly hole. The telescopic end of the first electric lifting table 5 faces vertically upward and is fixedly installed with an electric turntable 6. As Figure 4 shown, two suspension frames 7 are fixedly installed on both sides of the conveyor 1. Vertically arranged first electric push rods 8 are fixedly installed on the tops of the suspension frames 7. The telescopic ends of the two first electric push rods 8 on the same side are fixedly installed with the same correction beam 9. The two correction beams 9 are symmetrically arranged and are both slidably installed on the top of the box sealing table 4. As Figure 2 shown, support platforms 10 are arranged on both sides of the conveyor 1, and deviation correction mechanisms for correcting the positions of cardboard boxes are arranged on the tops of the support platforms 10. Specifically, when this automatic box sealing machine with adaptive deviation correction is in use, the cardboard box to be sealed is placed on one end of the conveyor 1, and the conveyor 1 transports the cardboard box. When the cardboard box is transported between the two deviation correction mechanisms, the position of the cardboard box is corrected. Then the cardboard box continues to be transported to the bottom of the box sealing mechanism body 3. At this time, the cardboard box is located on the top of the box sealing table 4. The first electric push rods 8 on both sides drive the correction beam 9 to slide on the box sealing table 4 until it contacts the cardboard box, so as to perform secondary correction and limit on the cardboard box. Then the electric lifting frame 2 drives the box sealing mechanism body 3 to descend to seal the cardboard box. Then the correction beam 9 releases the cardboard box. The first electric lifting table 5 drives the electric turntable 6 to lift in the first assembly hole until it contacts the bottom of the cardboard box and lifts the cardboard box. At this time, the electric turntable 6 drives the cardboard box to rotate to change the position of the cardboard box. Then the box sealing mechanism body 3 descends again to perform secondary sealing on the cardboard box, completing the box sealing process of the cardboard box.

[0020] As Figure 5As shown, the deviation correction mechanism includes an electric lifting rod 11 arranged on the top of the support platform 10, the telescopic end of the electric lifting rod 11 is vertically upward and fixedly installed with a lifting slide 12, two horizontally arranged horizontal slide rods 13 are slidably installed on the lifting slide 12, and the same deviation correction beam 14 is fixedly installed between the two horizontal slide rods 13 located on the same side, and a horizontally arranged second electric push rod 15 is fixedly installed inside the lifting slide 12, and the telescopic end of the second electric push rod 15 located at the same place is fixedly installed on the side wall of the deviation correction beam 14 , two correcting beams 14 are symmetrically arranged on the top of the conveyor 1; specifically, by setting up a correcting mechanism, when the carton is transported between the two correcting mechanisms, the electric lifting rod 11 will drive the two correcting beams 14 to lift up and down to adapt to the height of the current carton, and then the second electric push rods 15 on both sides drive the two correcting beams 14 to move toward the carton until they contact the carton, and then the carton is automatically pushed by the correcting beams 14 to return to the correct position, completing automatic correction, and preventing the carton from being misaligned with the sealing mechanism body 3 and affecting the sealing accuracy.

[0021] like Figure 6 As shown, a deviation-correcting conveyor belt 16 is fixedly installed inside the deviation-correcting beam 14. Figure 7 As shown, a plurality of evenly distributed hanging strips 20 are fixedly installed on the side walls of the deflection correction conveyor belt 16. In this embodiment, the deflection correction conveyor belt 16 is fixed as a whole inside the deflection correction beam 14. The deflection correction conveyor belt 16 is divided into a transmission toothed belt and a group of transmission toothed rollers. The transmission toothed rollers are rotatably installed inside the deflection correction beam 14. The transmission toothed belt is meshed with the transmission toothed rollers and is tensionedly sleeved on the transmission toothed rollers and driven by a transmission motor. The hanging strips 20 are vertically arranged and evenly distributed on the peripheral side walls of the transmission toothed belts. Specifically, by arranging the deflection correction conveyor belt 16, when the deflection correction beam 14 moves toward the carton, the deflection correction conveyor belts 16 on both sides will slowly rotate in the opposite direction. When the paper When there is a certain positional offset between the box as a whole and the sealing mechanism body 3, the deflection correction conveyor belt 16 will first contact the side of the carton, so that the hanging strip 20 on the side of the deflection correction conveyor belt 16 is stuck on the side of the carton, thereby driving the carton to rotate. When the carton returns to the correct position, the side wall of the carton will be parallel to the deflection correction conveyor belt 16. At this time, the deflection correction conveyor belt 16 stops rotating, and the deflection correction beams 14 on both sides drive the stationary deflection correction conveyor belt 16 to clamp the carton and limit the position, completing the deflection correction of the carton. The deflection correction conveyor belt 16 that rotates in the opposite direction drives the carton to rotate in advance, thereby avoiding direct rigid contact between the deflection correction beams 14 on both sides and the side of the carton, thereby preventing the problem of damage to the side of the carton.

[0022] like Figure 2 As shown, a linear guide rail 18 is fixedly installed on the top of the support platform 10. Figure 5As shown, an electric slider 17 is driven and installed on the top of the linear guide 18, and two electric lifting rods 11 are fixedly installed on the top of the two electric sliders 17 respectively; specifically, by setting the electric slider 17 and the linear guide 18, after the carton is straightened and clamped and limited by the correcting beam 14, the electric sliders 17 on both sides will drive the electric lifting rods 11 to drive the correcting beam 14 on the top to move along the linear guide 18, so that the carton is conveyed to the bottom of the sealing mechanism body 3 under the condition of being limited. When the carton is conveyed to the first electric lifting platform 5, the correcting mechanism releases and resets the carton, and the correction beams 9 on both sides will replace the correcting beam 14 to limit the carton, so as to prevent the carton from being shifted again during the transportation process after the correction.

[0023] like Figure 5 As shown, height measuring frames 19 are fixedly installed on the top of the two horizontal sliding bars 13 at the top, and the two height measuring frames 19 are symmetrically distributed and respectively located on the top of the two correcting beams 14; specifically, by setting the height measuring frames 19, before the correcting mechanism corrects the position of the carton, the electric lifting rod 11 will drive the two correcting beams 14 to move up and down, thereby driving the height measuring frames 19 on both sides to contact the top of the carton and measure the height of the carton, thereby facilitating the height adjustment of the sealing mechanism body 3.

[0024] like Figure 3 As shown, a deflection correction platform 21 is fixedly installed inside the conveyor 1. In the present embodiment, the sealing platform 4 is at the same height as the upper surface of the deflection correction platform 21. A second assembly hole is opened inside the deflection correction platform 21. A second electric lifting platform 22 is fixedly installed inside the second assembly hole. A deflection correction turntable 23 is rotatably installed on the top of the second electric lifting platform 22. Specifically, by setting the second electric lifting platform 22, after the carton is transported to the top of the deflection correction platform 21 by the conveyor 1, the second electric lifting platform 22 inside the second assembly hole will drive the deflection correction turntable 23 to lift up and lift the carton for a short distance. After that, when the deflection correction mechanism corrects the carton, the carton will rotate, and the deflection correction turntable 23 will separate the bottom of the carton from the second electric lifting platform 22 and the deflection correction platform 21, so that the carton can rotate smoothly without causing bottom wear. When the correction is completed, the second electric lifting platform 22 drives the carton to reset.

[0025] like Figure 1 As shown, a measuring gantry 24 is fixedly installed at one end of the conveyor 1 away from the electric lifting frame 2. Figure 8As shown, a first ultrasonic measuring instrument 25 is fixedly installed on the top of the measuring gantry 24, oblique frames 26 are fixedly installed on both sides of the top of the measuring gantry 24, and a second ultrasonic measuring instrument 27 is fixedly installed on one side of the oblique frame 26, and the first ultrasonic measuring instrument 25 and the second ultrasonic measuring instrument 27 are both facing the conveyor 1; specifically, by arranging the first ultrasonic measuring instrument 25 and the second ultrasonic measuring instrument 27, when the carton is sent to one end of the conveyor 1, the carton will pass through the measuring gantry 24, and then be scanned by the first ultrasonic measuring instrument 25 directly above and the second ultrasonic measuring instruments 27 obliquely above on both sides, so as to detect the external structure of the carton, and obtain the approximate data of the current length, width, height and orientation of the carton, so as to provide a reference for the subsequent position adjustment of the sealing mechanism body 3 and the operation of the deviation correction mechanism.

[0026] like Figure 4 As shown, a material unloading conveyor belt 28 is fixedly installed inside the correction beam 9. In the present embodiment, the material unloading conveyor belt 28 has the same structure as the deviation correction conveyor belt 16, and the size difference shall be subject to the actual situation. Specifically, by setting the material unloading conveyor belt 28, when the carton is transported to the bottom of the sealing mechanism body 3, the correction beams 9 on both sides can clamp the material unloading conveyor belt 28 on both sides of the carton, thereby driving the carton to move forward and backward, changing the front and rear position of the carton, so as to cooperate with the sealing operation of the sealing mechanism body 3, and at the same time facilitate the unloading of the carton.

[0027] In summary: when the adaptive deflection-correcting carton sealing machine is in use, the carton to be sealed is placed on one end of the conveyor 1, so that the conveyor 1 transports the carton. When the carton is transported between the two deflection-correcting mechanisms, the position of the carton will be corrected, and then the carton continues to be conveyed to the bottom of the carton sealing mechanism body 3. At this time, the carton is located on the top of the carton sealing platform 4, and the first electric push rods 8 on both sides drive the correction beam 9 to slide on the carton sealing platform 4 until it contacts the carton, thereby performing secondary correction and limiting on the carton. After that, the electric lifting frame 2 drives the carton sealing mechanism body 3 to descend to seal the carton, and then the correction beam 9 releases the carton, and the first electric lifting platform 5 drives the electric turntable 6 to lift in the first assembly hole until it contacts the bottom of the carton and lifts the carton. At this time, the electric turntable 6 drives the carton to rotate The carton is then rotated and the carton is replaced. The sealing mechanism body 3 then descends again to perform secondary sealing on the carton to complete the carton sealing process. By setting a deviation-correcting mechanism, when the carton is transported between the two deviation-correcting mechanisms, the electric lifting rod 11 drives the two deviation-correcting beams 14 to lift up and down to adapt to the height of the current carton. Then, the second electric push rods 15 on both sides drive the two deviation-correcting beams 14 to move toward the carton until they contact the carton, and then the carton is automatically pushed by the deviation-correcting beams 14 to return to the correct position, completing automatic deviation correction to prevent the carton from being misaligned with the sealing mechanism body 3 and affecting the accuracy of sealing. By setting a deviation-correcting conveyor belt 16, when the deviation-correcting beam 14 moves toward the carton, the deviation-correcting conveyor belts 16 on both sides will rotate slowly in the opposite direction. When the carton as a whole is relative to the sealing mechanism body 3 When there is a certain position deviation, the deflection correction conveyor belt 16 will first contact the side of the carton, so that the hanging strip 20 on the side of the deflection correction conveyor belt 16 is stuck on the side of the carton, thereby driving the carton to rotate. When the carton returns to the correct position, the side wall of the carton will be parallel to the deflection correction conveyor belt 16. At this time, the deflection correction conveyor belt 16 stops rotating, and the deflection correction beams 14 on both sides drive the stationary deflection correction conveyor belt 16 to clamp the carton to a limited position, thereby completing the deflection correction of the carton. The deflection correction conveyor belt 16 that rotates in the opposite direction drives the carton to rotate in advance, thereby avoiding direct rigid contact between the deflection correction beams 14 on both sides and the side of the carton, thereby preventing the problem of damage to the side of the carton. By arranging the electric slider 17 and the linear guide rail 18, after the carton returns to the correct position and is clamped and limited by the deflection correction beam 14, the electric sliders 17 on both sides will The electric lifting rod 11 is driven to drive the top correcting beam 14 to move along the linear guide rail 18, so that the carton is conveyed to the bottom of the sealing mechanism body 3 under the condition of being limited. When the carton is conveyed to the first electric lifting platform 5, the correcting mechanism releases and resets the carton, and the correction beams 9 on both sides will replace the correcting beam 14 to limit the carton, so as to prevent the carton from being offset again during the conveying process after the correction. By setting the height measuring frame 19, before the correcting mechanism corrects the position of the carton, the electric lifting rod 11 will drive the two correcting beams 14 to move up and down, thereby driving the height measuring frames 19 on both sides to contact the top of the carton and measure the height of the carton, so as to facilitate the height adjustment of the sealing mechanism body 3. By setting the second electric lifting platform 22,After the carton is transported to the top of the deflection correction platform 21 by the conveyor 1, the second electric lifting platform 22 inside the second assembly hole will drive the deflection correction turntable 23 to lift up and lift the carton for a short distance. After that, when the deflection correction mechanism corrects the carton, the carton will rotate, and the deflection correction turntable 23 will separate the bottom of the carton from the second electric lifting platform 22 and the deflection correction platform 21, so that the carton can rotate smoothly without causing bottom wear. When the correction is completed, the second electric lifting platform 22 drives the carton to reset. By setting the first ultrasonic measuring instrument 25 and the second ultrasonic measuring instrument 27, when the carton is sent to one end of the conveyor 1, the carton will pass through the measuring gantry. The rack 24 is then scanned by the first ultrasonic measuring instrument 25 directly above and the second ultrasonic measuring instruments 27 on both sides obliquely above, so as to detect the external structure of the carton and obtain the approximate data of the length, width, height and orientation of the current carton, so as to provide a reference for the subsequent position adjustment of the sealing mechanism body 3 and the operation of the deviation correction mechanism. By setting the unloading conveyor belt 28, when the carton is transported to the bottom of the sealing mechanism body 3, the correction beams 9 on both sides can clamp the unloading conveyor belt 28 on both sides of the carton, thereby driving the carton to move forward and backward, changing the front and rear orientation of the carton, so as to cooperate with the sealing operation of the sealing mechanism body 3, and at the same time facilitate the unloading of the carton.
