Technical Field

[0001] The invention relates to the technical field of palletizing devices, and in particular to a quantitative palletizing and feeding device for printing and slitting fluorescent posters. Background Art

[0002] Fluorescent posters are a type of poster designed and printed using fluorescent colors. They are widely used in various fields due to their unique color effects and strong visual impact. In advertising, fluorescent posters can attract people's attention and convey product information. In exhibitions, fluorescent posters can create a unique atmosphere and attract visitors. In artistic creation, fluorescent posters can become one of the media for expressing personality and creativity.

[0003] After the fluorescent posters are printed, they are first stacked and loaded, and then transported for slitting.

At the same time, the volume of the air chamber above the stacking plate is simultaneously reduced, and the adsorption effect on the fluorescent posters is automatically released, so as to achieve the placement and stacking effect of the lowered lifting plate. In addition, the reverse movement of the two groups of push seats makes it possible for the lifting plate to automatically restore its initial position above the feed conveying platform when it is deflected 180° and then descends, so as to ensure the continuity and efficiency of the fluorescent poster stacking process.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 6 As shown, in this embodiment, a quantitative stacking and feeding device for printing and slitting fluorescent posters comprises a base 1, and a feeding conveyor platform 11 and a feeding conveyor platform 12 are respectively fixedly connected to the top two sides of the base 1, the feeding conveyor platform 11 is used to convey the printed fluorescent posters to the adsorption and grabbing area of ​​the stacking component 3, and the feeding conveyor platform 12 is used to convey the stacked fluorescent posters to the slitting equipment for slitting processing, and the height of the feeding conveyor platform 11 is higher than that of the feeding conveyor platform 12, so as to reduce the lifting cycle of the stacking component 3, thereby improving the stacking efficiency;

[0040] A control panel 13 is fixedly mounted on the base 1, and is used to control the entire stacking and loading process of the stacking and loading device. A stacking assembly 2 is arranged on the top of the base 1, and the stacking assembly 2 includes two sets of mounting plates 21 welded on the top of the base 1, and stacking plates 22 are slidably connected between the mounting plates 21;

[0041] A stacking assembly 3 is arranged between the tops of the mounting plates 21. The stacking assembly 3 includes a T-shaped plate 31 welded between the two groups of mounting plates 21. A lifting plate 33 is fixedly connected to the T-shaped plate 31 through an electric push rod 32. Suction seats 34 are symmetrically fixedly connected to the bottom of the lifting plate 33 on both sides. A plurality of vacuum suction cups 35 are arranged at the bottom of the suction seat 34. The electric push rod 32 drives the lifting plate 33 to move downward. The plurality of vacuum suction cups 35 on the suction seats 34 on both sides of the bottom of the lifting plate 33 first contact with the fluorescent poster on the feeding conveying platform 11, and then the fluorescent poster is fixed by the vacuum suction cups 35. The lifting plate 33 is driven to rise in cooperation with the electric push rod 32 to achieve the adsorption and grabbing of the fluorescent poster.

[0042] The bottom of the T-shaped plate 31 is fixedly connected with a fixing sleeve 4 which cooperates with the electric push rod 32 to drive the lifting plate 33 to rotate. After the electric push rod 32 drives the lifting plate 33 to rise, it cooperates with the fixing sleeve 4 to synchronously deflect 180°, thereby synchronously achieving the effect of transportation.

[0043] A feeding conveyor belt 14 is rotatably installed on the feeding conveyor platform 11, and the printed fluorescent posters are conveyed by the feeding conveyor belt 14 on the feeding conveyor platform 11. The feeding conveyor belt 14 is driven by an external motor. A loading conveyor belt 15 is rotatably installed on the loading conveyor platform 12, and the stacked fluorescent posters are conveyed to the slitting equipment by the loading conveyor belt 15. The loading conveyor belt 15 is driven by an external motor, and two groups of rotating rods 16 are rotatably connected on one side of the loading conveyor platform 12 close to the feeding conveyor platform 11, and a plurality of discharging belts 17 are equidistantly arranged between the rotating rods 16, and a pulley 18 that is transmission-connected to the corresponding discharging belts 17 is fixedly connected to the rotating rods 16;

[0044] After the fluorescent posters are stacked, the stacking plate 22 is controlled to descend quickly so that the discharge belts 17 on the loading conveyor platform 12 contact the bottom of the stacked fluorescent posters. The rotating rod 16 is driven to rotate by an external motor and combined with the corresponding pulley 18 to drive the fluorescent posters to move, and the fluorescent posters are transferred to the loading conveyor belt 15.

[0045] Two sets of slide rails 23 are fixedly connected to one side of the mounting plate 21, and a slide seat 24 slidably connected to the corresponding slide rails 23 is fixedly connected to the stacking plate 22. The slide rails 23 and the slide seat 24 are used to improve the stability of the stacking plate 22 in lifting and lowering. A lifting screw 25 is rotatably mounted on the mounting plate 21, and a threaded seat 26 threadedly connected to the corresponding lifting screw 25 is fixedly connected to the stacking plate 22. A lifting motor 27 for driving the lifting screw 25 to rotate is bolted to the mounting plate 21. During the stacking of multiple fluorescent posters, the controller in the control panel 13 controls the lifting motor 27 to drive the corresponding lifting screw 25 to rotate slowly, thereby driving the stacking plate 22 to slowly descend.

[0046] A height-adjustable photoelectric sensor is installed on a mounting plate 21 on one side. The installation position of the photoelectric sensor is at the height of the fluorescent poster stacking. When the photoelectric sensor collects a signal that the stacking plate 22 blocks the light emitted by it, the collected stop signal is transmitted to the controller in the control panel 13. The controller controls the feed conveyor belt 14 to stop rotating, and stops the electric push rod 32 from driving the lifting plate 33 to lift and lower, so as to complete the quantitative stacking of the fluorescent posters. After the fluorescent posters are stacked, the controller controls the lifting motor 27 to cooperate with the lifting screw 25 to drive the stacking plate 22 to descend rapidly, thereby quickly realizing the operation of stacking and loading the fluorescent posters. A through slot 28 is provided on the top of the stacking plate 22 for the corresponding discharge belt 17 to pass through. After the stacking plate 22 is lowered, the discharge belt 17 can effectively contact the bottom of the stacked fluorescent posters through multiple through slots 28.

[0047] Two groups of vertical grooves 41 are symmetrically provided on the annular outer wall of the fixed sleeve 4, and spiral grooves 42 are provided between adjacent vertical grooves 41. A guide block 43 is fixedly connected in the vertical groove 41 and at the top of the lower end of the corresponding spiral groove 42. A guiding slope is provided on the top of the guide block 43, and the upper end of the spiral groove 42 is located above the corresponding guide block 43.

[0048] The top of the lifting plate 33 is symmetrically fixedly connected with an arc plate 36 that is slidably connected to the fixed sleeve 4. The arc plate 36 can enhance the stability of the lifting plate 33 during rotation. A guide pin 37 that is adapted to the corresponding vertical groove 41 is slidably connected to the arc plate 36. A spring 38 is fixedly connected between the end of the guide pin 37 away from the fixed sleeve 4 and the arc plate 36. The electric push rod 32 drives the lifting plate 33 to move downward, and the guide pin 37 slides in the corresponding vertical groove 41 to increase the downward stability of the lifting plate 33 and prevent rotation during the descent process. The guide inclined surface provided at the top of the guide block 43, the sliding connection between the guide pin 37 and the arc plate 36, and the spring 38 are provided to avoid affecting the downward sliding of the guide pin 37 from the spiral grooves 42 on both sides in the vertical groove 41.

[0049] When the electric push rod 32 drives the lifting plate 33 to rise, the guide pin 37 first slides in the vertical groove 41 to separate the adsorbed and grabbed fluorescent poster from the feed conveyor belt 14, and then the guide pin 37 enters the spiral groove 42 under the guidance of the guide block 43, thereby synchronously driving the lifting plate 33 to deflect 180°, so that the adsorbed and grabbed fluorescent poster is rotated to the top of the stacking plate 22, and the suction seat 34 on the other side is rotated to the top of the feed conveyor platform 11, preparing for the next descent of the lifting plate 33. Only by driving the lifting plate 33 to lift once by the electric push rod 32, the adsorption, grabbing and transportation steps of the fluorescent poster can be quickly completed, thereby simplifying the operating steps of the existing device, shortening the stacking cycle and improving the stacking efficiency of the fluorescent posters.

[0050] The vacuum suction cup 35 is fixedly connected with a connecting pipe 39 which is slidably connected with the suction seat 34. Through the setting of the connecting pipe 39, after the vacuum suction cup 35 comes into contact with the fluorescent poster, a negative pressure vacuum is applied to the inside thereof to achieve the effect of adsorption and grasping. A spring 2 310 is fixedly connected between the vacuum suction cup 35 and the suction seat 34 and on the outside of the connecting pipe 39.

[0051] Example 2: Please refer to Figure 6-Figure 11 As shown, in this embodiment, a suction assembly 5 cooperating with the vacuum suction cup 35 is provided at the bottom of the lifting plate 33, and the suction assembly 5 includes a square sleeve 51 fixedly connected between the two groups of suction seats 34, and two groups of piston plates 52 are symmetrically arranged in the square sleeve 51. The negative pressure environment in the corresponding suction seat 34 is realized by sliding the two groups of piston plates 52 in the square sleeve 51, and the negative pressure environment in the vacuum suction cup 35 is realized in combination with the connecting pipe 39.

[0052] A connecting pipe 39 is fixedly connected to the vacuum suction cup 35 and is slidably connected to the suction seat 34. A second spring 310 is fixedly connected between the vacuum suction cup 35 and the suction seat 34 and on the outside of the connecting pipe 39. The vacuum suction cup 35 slides with the suction seat 34 through the connecting pipe 39, so that during the descending movement of the lifting plate 33, the vacuum suction cup 35 can avoid contact with the fluorescent poster and limit the continuous descent of the lifting plate 33, thereby driving the suction component 5 and the fixed sleeve 4 to cooperate with each other, and then promote the movement of the piston plate 52. The set spring 2 310 is used to ensure a large extrusion force after the grasped fluorescent poster contacts the stacking plate 22, so as to avoid the problem of forcing the fluorescent poster to move during the exhaust process as the lifting plate 33 descends and the corresponding negative pressure state inside the suction seat 34 is released, thereby causing the stacking effect to be poor.

[0053] An air chamber 53 connected to the suction seats 34 on both sides is provided in the square sleeve 51, and the air chamber 53 is slidably connected to the two groups of piston plates 52. A moving block 55 is fixedly connected between the two groups of piston plates 52 through a support rod 54. The moving block 55 slides in the air chamber 53, driving the piston plates 52 on both sides to move synchronously, so as to realize the reverse change of the volume on both sides of the air chamber 53. A movable groove 56 penetrating the square sleeve 51 is provided at the top of the lifting plate 33 and located between the moving block 55 and the corresponding piston plate 52. A push seat 57 is slidably connected in the movable groove 56, and a guide groove 1 58 is provided on one side of the push seat 57. A guide groove 2 59 matching the corresponding guide groove 1 58 is provided on the moving block 55.

[0054] After the vacuum suction cup 35 contacts the fluorescent poster, the push seat 57 above the feed conveyor platform 11 moves upward, and with the cooperation of the corresponding guide groove 2 59 and the guide groove 1 58, the moving block 55 is pushed to drive the two sets of piston plates 52 to move away from the feed conveyor belt 14, thereby increasing the volume of the air chamber 53 above the feed conveyor belt 14, so that a negative pressure environment is generated in the corresponding suction seat 34, and the vacuum suction cup 35 is cooperated to adsorb and grab the fluorescent poster. In this process, with the movement of the moving block 55, with the help of the guide groove 2 59 on the other side of the moving block 55 and the guide groove 1 58 on the push seat 57 close to the stacking plate 22, the push seat 57 close to the stacking plate 22 is forced to move downward, thereby reducing the volume of the air chamber 53 above the stacking plate 22, automatically releasing the negative pressure environment in the suction seat 34 above the stacking plate 22, and releasing the fluorescent poster on the stacking plate 22.

[0055] By the reverse movement of the two groups of push seats 57, the lifting plate 33 is deflected 180°, and the position of the push seat 57 located above the feed conveying platform 11 is the initial position, which can directly cooperate with the descent of the lifting plate 33 to perform an upward movement, further simplifying the steps of resetting the push seat 57, thereby ensuring the continuity and efficiency of the fluorescent poster stacking process.

[0056] The top of the push seat 57 is fixedly connected with an L-shaped plate 510 extending to the inside of the fixed sleeve 4, and the annular inner wall of the fixed sleeve 4 away from the stacking plate 22 is fixedly connected with an abutment block 44. When the lifting plate 33 is in the process of descending, when the vacuum suction cup 35 contacts the fluorescent poster, the L-shaped plate 510 of the push seat 57 above the feeding conveying platform 11 contacts the abutment block 44, and as the lifting plate 33 continues to descend, the push seat 57 is restricted from following the descent, thereby achieving the effect of the push seat 57 moving upward relative to the suction seat 34, thereby simultaneously completing the purpose of adsorption and grasping.

[0057] The push seat 57 is symmetrically provided with spring grooves on both sides, and a limit pin 512 slidably connected thereto is fixedly connected to the inside of the spring groove through a spring three 511. A limit groove slidably connected to the end of the corresponding limit pin 512 is provided on the inner side wall of the movable groove 56, and an upper limit groove 513 and a lower limit groove 514 are respectively provided on the top and bottom sides of the limit groove. When the push seat 57 above the feed conveying platform 11 moves upward relative to the suction seat 34, the limit pin 512 is compressed by the spring three 511. The lower part is engaged with the corresponding upper limit slot 513, and the pushing seat 57 above the stacking plate 22 moves downward relative to the suction seat 34. The limit pin 512 is engaged with the corresponding lower limit slot 514 under the compression of the spring three 511, thereby effectively avoiding the problem that when the lifting plate 33 moves upward, the L-shaped plate 510 is separated from the abutment block 44, and the negative pressure environment in the suction seat 34 above the feed conveying platform 11 causes the moving block 55 to reset, making it difficult to ensure the adsorption and grasping of the fluorescent poster.

[0058] Example 3: Please refer to Figure 1-Figure 11 As shown, the present invention also proposes a working method of a quantitative stacking and feeding device for fluorescent poster printing and slitting, comprising the following steps:

[0059] S1: The printed fluorescent poster is conveyed by the feed conveyor belt 14 on the feed conveyor table 11, and the electric push rod 32 drives the lifting plate 33 to move downward. At this time, the guide pin 37 only slides in the vertical slot 41 to ensure the stable descent of the lifting plate 33, so that the multiple vacuum suction cups 35 on the suction seat 34 below the lifting plate 33 contact with the fluorescent poster on the feed conveyor belt 14, and push the connecting pipe 39 to slide in the suction seat 34;

[0060] S2: When the vacuum suction cup 35 contacts the fluorescent poster, the L-shaped plate 510 on one side contacts the abutment block 44, forcing the corresponding push seat 57 to move upward, and under the cooperation of the guide groove 2 59 and the guide groove 1 58, the moving block 55 drives the piston plate 52 to move away from the feeding conveyor belt 14, increasing the volume of the air chamber 53 above the feeding conveyor belt 14, so that a negative pressure environment is generated in the corresponding suction seat 34, until the limit pin 512 on the push seat 57 is engaged with the corresponding upper limit slot 513, completing the adsorption and grabbing of the fluorescent poster;

[0061] S3: The electric push rod 32 drives the lifting plate 33 to move upward, and during the upward process, the guide pin 37 enters the spiral groove 42 under the guidance of the guide block 43, thereby synchronously driving the lifting plate 33 to deflect 180°, so that the adsorbed and grasped fluorescent poster is rotated to the top of the stacking plate 22;

[0062] S4: Repeat steps S1-S3 to lower the lifting plate 33 again, and continue to absorb and grab the fluorescent posters on the feeding conveyor belt 14 with the help of the suction seat 34 on the other side below the lifting plate 33, while stacking the previous fluorescent poster on the stacking plate 22, and drive the two groups of piston plates 52 to move with the moving block 55, thereby increasing the volume of the air chamber 53 above the feeding conveyor belt 14 and reducing the volume of the air chamber 53 above the stacking plate 22, automatically releasing the negative pressure environment in the suction seat 34 above the stacking plate 22, and automatically releasing the fluorescent posters on the stacking plate 22;

[0063] S5: While stacking multiple fluorescent posters, the lifting motor 27 drives the corresponding lifting screw 25 to rotate slowly, driving the stacking plate 22 to slowly descend, and a height-adjustable photoelectric sensor is installed on one side mounting plate 21. The installation position of the photoelectric sensor is the height of the fluorescent poster stacking. When the photoelectric sensor collects a signal that the stacking plate 22 blocks the light emitted by it, the collected stop signal is transmitted to the controller in the control panel 13. The controller controls the feed conveyor belt 14 to stop rotating, and stops the electric push rod 32 from driving the lifting plate 33 to move up and down, thereby completing the quantitative stacking of the fluorescent posters;

[0064] S6: The controller in the control panel 13 controls the lifting motor 27 to cooperate with the lifting screw 25 to drive the stacking plate 22 to descend rapidly, so that each discharge belt 17 on the loading conveyor platform 12 passes through the through groove 28 to contact the bottom of the stacked fluorescent posters, and transfers the fluorescent posters to the loading conveyor belt 15, and the stacked fluorescent posters are transported to the slitting equipment through the loading conveyor belt 15, and at the same time drive the stacking plate 22 to rise and reset, and stack the fluorescent posters again.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
