Description

Technical Field

[0001] The invention belongs to the technical field of shoe packaging, and relates to a packaging device, in particular to a shoemaking packaging device with a missing packing detection function. Background Art

[0002] Shoes are a tool for people to protect their feet from injury, and they are divided into many different types due to different functions and different aesthetics. They are one of the most core consumables in daily life. In the process of shoe production, in order to ensure that the shoes are safe and maintain sufficient aesthetics during storage and transportation, special equipment is usually used for packaging. Shoe boxes are a type of shoe packaging. Shoes are placed in the box and then covered with a lid for packaging and transportation.

[0003] A search revealed a Chinese patent document [Application Number: CN202020843624.0; Publication Number: CN210853118U], which discloses a shoe packaging device. This shoe packaging device includes a shoe conveyor, a shoe box conveyor, a box lid conveyor, and a gripping and transferring mechanism. The shoe box conveyor is located between the shoe conveyor and the box lid conveyor. The gripping and transferring mechanism includes a horizontal moving mechanism, a vertical moving mechanism mounted on an actuating end of the horizontal moving mechanism, and a mounting plate fixed to the actuating end of the vertical moving mechanism. A first gripping mechanism for gripping a pair of shoes and a second gripping mechanism for gripping the box lid are mounted on the mounting plate. The distances between the shoe conveyor and the shoe box conveyor, the distance between the shoe box conveyor and the box lid conveyor, and the distance between the first gripping mechanism and the second gripping mechanism are all the same.

[0004] The device disclosed in this patent solves the technical problem of low shoe box packing efficiency in the prior art. However, during use, shoe boxes may be missing due to operational errors or negligence of the staff. The above-mentioned device cannot detect the shoe boxes. The staff opens the box lid to conduct sampling detection for missing shoes, which is not only labor-intensive but also cannot detect all shoe boxes. Although some companies currently use perspective technology to check from the side whether there are missing shoes in the shoe box, the equipment cost is too expensive. Moreover, when only one shoe is missing in the shoe box, the equipment can detect that there are shoes in the shoe box, but cannot detect whether there is a pair of shoes or a single shoe in the shoe box, which also has defects. Moreover, after packaging, if the shoe box lid is not closed tightly, it is easy to cause the shoe box lid to fall off, affecting the packaging effect. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a shoe packaging device with a missing packing detection function. The shoe packaging device with a missing packing detection function can not only compact the shoe box lid during transportation, but also detect the number of shoes in the shoe box by weighing.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A shoe packaging device with a missing assembly detection function comprises a packaging mechanism, a controller, a first conveyor belt and a second conveyor belt, wherein a fixed plate is bolted to the top of the first conveyor belt, four corners of the bottom of the fixed plate are bolted to hydraulic rods, the output shaft of the hydraulic rod is bolted to a lifting plate, a plurality of elastic structures are fixed to the bottom of the lifting plate, a frame is fixed to the bottom of the elastic structure, a pressure roller is rotatably connected to the surface of the inner side of the frame, a first slope is bolted to one side of the first conveyor belt, a first baffle and a second baffle are bolted to both sides of the top of the second conveyor belt, a plurality of fans are also fixed to one side of the top of the second conveyor belt, a second slope is bolted to the other side of the top of the second conveyor belt, and the second slope is fixed to the bottom of the second conveyor belt. A first collecting structure is provided below, an upper plate is provided above the end of the second conveyor belt, a supporting platform is provided below the upper plate, an electronic scale is bolted to the top of the support platform, a placing platform is fixed to the top of the electronic scale, a third slope and a fourth slope are bolted to both sides of the support platform, screws are fixed to both sides of the bottom of the upper plate through bearing seats, a threaded sleeve is threaded on the surface of the screw, a fixing frame is bolted to the bottom of the threaded sleeve, a fixing rod is bolted to the four corners of the bottom of the fixing frame, a push plate is bolted to the bottom end of the fixing rod, a driving motor is bolted to one side of the top of the upper plate, the output shaft of the driving motor is connected to the screw through a belt drive, and a second collecting structure is provided below the third slope.

[0008] The working principle of the present invention is as follows: the first conveyor belt can convey the packaged shoes; when the shoe box moves to the bottom of the pressure roller, the reaction force of the compression spring acts on the shoe box through the pressure roller, pressing the shoe box cover tightly; then the shoe box slides down the surface of the first slope to the surface of the second conveyor belt; when the shoe box approaches the fan, the first infrared sensor senses the approach of the shoe box, and the fan generates wind to blow on the surface of the shoe box; if the shoe box is empty, the empty box slides down the surface of the second slope to the inside of the first collection box; and if there is a shoe or a pair of shoes in the shoe box, the fan will not blow them away. , then the shoe box falls on the surface of the placement table, and the electronic scale weighs the shoe box. When the weighed value is much less than the weight of a pair of shoes, it means that there is only one shoe in the shoe box. The controller determines that the shoe box is missing, and then drives the motor to drive the screw to rotate. The threaded sleeve on the surface of the screw drives the fixed frame, vertical rod and push plate below to move together. The push plate moves in the direction of the third slope, pushing the missing shoe box to the top of the third slope, so that the missing shoe box falls into the second collection box. If the weighed number is the same as the weight of a pair of shoes, the shoe box is pushed to the top of the fourth slope.

[0009] The elastic structure includes a sleeve, a compression spring, a movable block and a vertical rod. The sleeve is bolted to the bottom of the lifting plate, the movable block is slidably connected to the inner wall of the sleeve, the top end of the compression spring is fixed to the inner wall of the sleeve, and the bottom end of the compression spring is fixed to the movable block, the vertical rod is bolted to the bottom end of the movable block, and the other end of the vertical rod is bolted to the frame.

[0010] With the above structure, the reaction force of the compression spring acts on the surface of the shoe box cover through the pressure roller to compact the shoe box cover.

[0011] The cross section of the movable block is designed to be circular, and the outer diameter of the movable block is larger than the size of the sleeve opening.

[0012] The above structure is adopted to prevent the reaction force of the compression spring from ejecting the movable block from the interior of the sleeve.

[0013] The first collection structure includes a first collection box, a first universal wheel, a first long pole and a first handle. The first universal wheels are in four groups and are bolted to the four corners of the bottom of the first collection box. The first long pole is bolted to one side of the first collection box. The first handle is fixed to the other end of the first long pole.

[0014] With the above structure, the empty boxes can fall into the first collection box for collection.

[0015] The second collection structure includes a second collection box, a second universal wheel, a second long pole and a second handle. The second universal wheel is bolted to the bottom of the second collection box, the second long pole is bolted to one side of the second collection box, and the second handle is fixed to the end of the second long pole away from the second collection box. The size of the second collection box is the same as that of the first collection box.

[0016] With the above structure, the shoe boxes that are missing can fall into the second collection box for collection.

[0017] A first buffer pad is fixed to the bottom of the inner cavity of the first collection box, and a second buffer pad is fixed to the bottom of the inner cavity of the second collection box.

[0018] With the above structure, they play a role in providing cushioning and protection for the shoe box.

[0019] The surface of the first slope is rotatably connected to a first roller, and the surface of the second slope is rotatably connected to a second roller.

[0020] The above structure facilitates the shoe box to slide down the surfaces of the first slope and the second slope.

[0021] The surface of the third slope is rotatably connected to a third roller, and the surface of the fourth slope is rotatably connected to a fourth roller.

[0022] The above structure facilitates the shoe box to slide down the surfaces of the third slope and the fourth slope.

[0023] A first infrared sensor and a second infrared sensor are fixed on the surface of the first baffle respectively. The first infrared sensor and the second infrared sensor are both electrically connected to the controller, the controller is electrically connected to the fan, the electronic scale is electrically connected to the controller, and the controller is electrically connected to the drive motor.

[0024] The above structure is used to monitor whether the shoe box is close to or away from the fan.

[0025] A plurality of balls are fixed on the top of the placing platform, and a limit plate is bolted to the other side of the top of the placing platform.

[0026] With the above structure, the shoe box can be easily moved on the surface of the placement table, and the limiting plate can prevent the shoe box from sliding off the other side of the placement table.

[0027] Compared with the existing technology, the shoe packaging device with missing detection function has the following advantages:

[0028] 1. The present invention compacts the shoe box cover during transportation to prevent it from falling off. It can also detect empty boxes by blowing air and blow the empty boxes away for recycling. At the same time, it can detect whether there are missing shoes in the shoe box by weighing. If there are missing shoes in the shoe box, the missing shoe box will be pushed away for recycling. This not only avoids the defect that the perspective equipment cannot effectively check the number of shoes in the shoe box, but also reduces the equipment cost.

[0029] 2. During the operation of the present invention, when the pressure roller touches the top of the shoe box cover, the pressure roller moves slightly upward, and then the vertical rod drives the movable block to move upward, and the compression spring is in a compressed state. After that, the reaction force of the compression spring acts on the surface of the shoe box cover through the movable block, the vertical rod, the frame and the pressure roller to compact the shoe box cover.

[0030] 3. During operation of the present invention, the empty boxes sliding down the second slope can fall into the interior of the first collection box, and the first universal wheels provided at the bottom of the first collection box enable it to move. At the same time, the provision of the first long rod and the first handle makes it convenient for the staff to push the first collection box to move. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0041] like Figures 1-8As shown, the shoe packaging device with the missing assembly detection function includes a packaging mechanism 1, a controller 2, a first conveyor belt 3 and a second conveyor belt 4. A fixed plate 5 is bolted to the top of the first conveyor belt 3, and hydraulic rods 6 are bolted to the four corners of the bottom of the fixed plate 5. The output shaft of the hydraulic rod 6 is bolted to a lifting plate 7. A plurality of elastic structures 8 are fixed to the bottom of the lifting plate 7, and a frame 9 is fixed to the bottom of the elastic structure 8. A pressure roller 10 is rotatably connected to the surface of the inner side of the frame 9. A first slope 11 is bolted to one side of the first conveyor belt 3, and a first baffle 13 and a second baffle 14 are bolted to both sides of the top of the second conveyor belt 4 respectively. A plurality of fans 15 are also fixed to one side of the top of the second conveyor belt 4, and a second slope 16 is bolted to the other side of the top of the second conveyor belt 4. A first collecting roller 11 is provided below the second slope 16. The collecting structure 18 is provided with an upper plate 19 above the end of the second conveyor belt 4, and a supporting platform 20 is provided below the upper plate 19. An electronic scale 21 is bolted to the top of the supporting platform 20, and a placing platform 22 is fixed to the top of the electronic scale 21. The third slope 25 and the fourth slope 27 are bolted to both sides of the supporting platform 20 respectively. Screws 29 are fixed to both sides of the bottom of the upper plate 19 through bearing seats. The surface of the screw 29 is threadedly connected to a threaded sleeve 30, and the bottom of the threaded sleeve 30 is bolted to a fixing frame 31. The four corners of the bottom of the fixing frame 31 are bolted to a fixing rod 32, and the bottom end of the fixing rod 32 is bolted to a push plate 33. A drive motor 34 is bolted to one side of the top of the upper plate 19, and the output shaft of the drive motor 34 is connected to the screw 29 through a belt drive. A second collecting structure 35 is provided below the third slope 25.

[0042] The elastic structure 8 includes a sleeve 81, a compression spring 82, a movable block 83 and a vertical rod 84. The sleeve 81 is bolted to the bottom of the lifting plate 7, the movable block 83 is slidably connected to the inner wall of the sleeve 81, the top of the compression spring 82 is fixed to the inner wall of the sleeve 81, and the bottom end of the compression spring 82 is fixed to the movable block 83, the vertical rod 84 is bolted to the bottom end of the movable block 83, and the other end of the vertical rod 84 is bolted to the frame 9. In this embodiment, when the pressure roller 10 touches the top of the shoe box cover, the pressure roller 10 moves slightly upward, and then the vertical rod 84 drives the movable block 83 to move upward, and puts the compression spring 82 in a compressed state. After that, the reaction force of the compression spring 82 acts on the surface of the shoe box cover through the movable block 83, the vertical rod 84, the frame 9 and the pressure roller 10 to compact the shoe box cover.

[0043] The cross-section of the movable block 83 is circular, and the outer diameter of the movable block 83 is larger than the size of the opening of the sleeve 81. In this embodiment, the movable block 83 is larger than the opening of the sleeve 81, thereby preventing the movable block 83 from detaching from the inside of the sleeve 81, and further preventing the reaction force of the compression spring 82 from popping the movable block 83 out of the inside of the sleeve 81.

[0044] The first collection structure 18 includes a first collection box 181, a first universal wheel 182, a first long rod 183 and a first handle 184. The first universal wheels 182 are in four groups and are bolted to the four corners of the bottom of the first collection box 181. The first long rod 183 is bolted to one side of the first collection box 181. The first handle 184 is fixed to the other end of the first long rod 183. In this embodiment, the empty box sliding down the second slope 16 can fall into the interior of the first collection box 181, and the first universal wheel 182 set at the bottom of the first collection box 181 enables it to move. At the same time, the setting of the first long rod 183 and the first handle 184 makes it convenient for the staff to push the first collection box 181 to move.

[0045] The second collection structure 35 includes a second collection box 351, a second universal wheel 352, a second long rod 353 and a second handle 354. The second universal wheel 352 is bolted to the bottom of the second collection box 351, the second long rod 353 is bolted to one side of the second collection box 351, and the second handle 354 is fixed to the end of the second long rod 353 away from the second collection box 351. The size of the second collection box 351 is the same as that of the first collection box 181. In this embodiment, the missing shoe boxes falling from the third slope 25 can fall into the interior of the second collection box 351. When the second collection box 351 is full, the staff can hold the second handle 354 and push the second collection box 351 to move through the second long rod 353 to process the missing shoe boxes in the second collection box 351.

[0046] A first buffer pad 185 is fixed to the bottom of the inner cavity of the first collection box 181, and a second buffer pad 355 is fixed to the bottom of the inner cavity of the second collection box 351. In this embodiment, when the empty box falls into the first collection box 181, the first buffer pad 185 can play a buffering role to prevent the empty box from being broken, and the second buffer pad 355 can also play a buffering and protective role inside the second collection box 351.

[0047] The surface of the first slope 11 is rotatably connected to the first roller 12, and the surface of the second slope 16 is rotatably connected to the second roller 17. In this embodiment, the shoe box falling from the surface of the first slope 11 can move on the surface of the first roller 12. The first roller 12 replaces sliding friction with rolling friction, thereby reducing the friction resistance encountered by the shoe box when sliding on the surface of the first slope 11, and the second roller 17 can reduce the friction resistance encountered by the empty box when sliding on the surface of the second slope 16.

[0048] The surface of the third slope 25 is rotatably connected to the third roller 26, and the surface of the fourth slope 27 is rotatably connected to the fourth roller 28. In this embodiment, the third roller 26 set on the surface of the third slope 25 can facilitate the shoe box to slide downward to the interior of the second collection box 351, while the fourth roller 28 facilitates the shoe box to slide on the surface of the fourth slope 27.

[0049] A first infrared sensor 36 and a second infrared sensor 37 are fixed to the surface of the first baffle 13 respectively. The first infrared sensor 36 and the second infrared sensor 37 are both electrically connected to the controller 2, the controller 2 is electrically connected to the fan 15, the electronic scale 21 is electrically connected to the controller 2, and the controller 2 is electrically connected to the drive motor 34. In this embodiment, the first infrared sensor 36 can monitor whether the shoe box is approaching. When the shoe box is approaching, the controller 2 controls the fan 15 to turn on for blowing air, and the second infrared sensor 37 can monitor whether the shoe box is moving away. When the shoe box is moving away, the controller 2 controls the fan 15 to turn off. At the same time, the electronic scale 21 can send the weighing result of the shoe box to the controller 2. The controller 2 determines whether the shoe box is missing. The controller 2 can control the start and stop of the drive motor 34 and the rotation direction of the output shaft to change the movement direction of the push plate 33 below.

[0050] A number of ball bearings 24 are fixed to the top of the placement table 22, and a limit plate 23 is bolted to the other side of the top of the placement table 22. In this embodiment, the shoe boxes falling from the second conveyor belt 4 can fall on the ball bearings 24 on the surface of the placement table 22. The ball bearings 24 facilitate the movement of the shoe boxes on the surface of the placement table 22, thereby facilitating the push plate 33 to push the shoe boxes to move. At the same time, the limit plate 23 can prevent the shoe boxes from sliding from the other side of the placement table 22.

[0051] It should be noted that the packaging mechanism 1 is a common shoe packaging machine in the prior art, and its specific structure and technology are currently very mature. The present invention aims to solve the problem of shoe box packaging leakage, and the specific working steps of the packaging mechanism 1 will not be repeated.

[0052] The working principle of the present invention is as follows: before working, first open the hydraulic rod 6 to drive the lifting plate 7 to descend, and the lifting plate 7 drives the elastic structure 8, frame 9 and pressure roller 10 below to descend together until the height of the pressure roller 10 is slightly higher than the height of the shoe box, and then place the shoe box containing a pair of shoes on the placement table 22 for weighing, and record the value. When working, the packaging mechanism 1 packs the shoes, and the first conveyor belt 3 can transport the packed shoe boxes. When the shoe box moves to the bottom of the pressure roller 10, the reaction force of the compression spring 82 acts on the pressure roller 10 through the pressure roller 10. The shoe box is placed on the shoe box, the shoe box cover is pressed tightly, and then the shoe box moves from the first conveyor belt 3 to the surface of the first slope 11, slides down the surface of the first slope 11 to the surface of the second conveyor belt 4, and the second conveyor belt 4 transports the shoe box. When the shoe box approaches the fan 15, the first infrared sensor 36 senses the shoe box approaching, and the controller 2 controls the fan 15 to turn on. The fan 15 generates wind to blow on the surface of the shoe box. If the shoe box is empty, the shoe box is easily blown away. The empty box slides down the surface of the second slope 16 to the inside of the first collection box 181, and there is a When a shoe or a pair of shoes is placed in the box, the fan 15 cannot blow it away. At this time, the shoe box continues to move. When the shoe box passes the second infrared sensor 37, the controller 2 controls the fan 15 to turn off. The shoe box continues to move with the second conveyor belt 4 and then falls on the surface of the placement table 22. The electronic scale 21 weighs the shoe box. When the weighed value is much less than the weight of a pair of shoes, it means that there is only one shoe in the shoe box. The controller 2 determines that the shoe box is missing and then drives the motor 34 to turn on. It drives the screw 29 to rotate through the belt. The threaded sleeve 30 on the surface of the screw 29 drives the screw below. The fixing frame 31, the vertical rod 84 and the push plate 33 move together, and the push plate 33 moves toward the direction of the third slope 25, pushing the missing shoe box to the top of the third slope 25, so that the missing shoe box falls into the second collection box 351. If the weighed quantity is the same as the weight of a pair of shoes, the controller 2 determines that the shoe box is not missing, and the controller 2 controls the output shaft of the drive motor 34 to make a reverse movement to make the push plate 33 approach the fourth slope 27, push the shoe box to the top of the fourth slope 27, and collect the shoe boxes falling on the fourth slope 27.

[0053] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
