Description

Technical Field

[0001] This utility model relates to the field of paper bag detection technology, and in particular to an automatic device for identifying and rejecting waste bags. Background Technology

[0002] After undergoing a series of processes such as folding, gluing, and conveying, industrial paper bags need to be inspected for quality before being discharged. One aspect of the quality inspection is to check whether there are any problems such as damage, misalignment of folds, or open seals on the surface of the paper bags. Any unqualified products identified need to be removed from the production line.

[0003] Existing technology typically involves conveying woven paper bags via a conveyor belt to a bag-collecting hub for packaging. Before packaging, workers must manually inspect and remove defective bags, which greatly increases the labor intensity of workers and causes uncertainty in the product qualification rate.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-7 This embodiment is an automatic waste bag identification and rejection device, including a frame component 100, a transmission component 200, a belt conveyor component 300, and an automatic waste rejection component 400. The frame component 100 includes main unit wall plates 102 disposed on both sides of the top of the base 101, a conveyor belt wall plate 103 connected to the main unit wall plates 102, and a support base 104 disposed at the bottom of the conveyor belt wall plate 103. The transmission component 200 includes a first rotating shaft 201 rotatably disposed between the two main unit wall plates 102, and a large hub wheel 20 is fixed to the outer wall of the first rotating shaft 201. 2. Multiple arc-shaped mounting plates 202b are circumferentially arranged on the outer wall of the large hub wheel 202. Two sliding grooves 202a are spaced apart in the middle of the outer wall of each arc-shaped mounting plate 202b. One end of the first rotating shaft 201 passes through the main unit wall plate 102 and is connected to the large hub gear 203. The large hub gear 203 is connected to the second transmission assembly 205 via the first transmission assembly 204. The belt conveyor component 300 includes a first upper conveyor belt assembly 301, a second upper conveyor belt assembly 302, and a conveyor belt wall plate 103, all disposed between the two main unit wall plates 102 and between the two conveyor belt wall plates 103. The lower conveyor belt assembly 303, the first upper conveyor belt assembly 301, and the second upper conveyor belt assembly 302 are spaced apart and located above the lower conveyor belt assembly 303. The large hub gear 203 drives the first upper conveyor belt assembly 301, the second upper conveyor belt assembly 302, and the lower conveyor belt assembly 303 through the first transmission assembly 204 and the second transmission assembly 205. The automatic waste rejection component 400 includes a PLC controller and a high-speed cylinder 401 disposed on one side of the conveyor belt wall plate 103. Waste rejection supports 402 are rotatably disposed on one side of the two conveyor belt wall plates 103 for waste rejection. A scrap removal plate 402a is provided at the top of the support 402. One end of the scrap removal support 402 passes through the conveyor belt wall plate 103 and is connected to a swing arm 403. One end of the swing arm 403 is rotatably connected to the end of the telescopic rod of the high-speed cylinder 401. A high-speed camera 404 is fixedly connected between the two main wall plates 102 through a fixing rod 102a. The high-speed camera 404 is located between the first upper conveyor belt assembly 301 and the second upper conveyor belt assembly 302. The high-speed camera 404 is electrically connected to the PLC controller. The high-speed cylinder 401 is connected to the PLC controller through a connected solenoid valve.

[0025] The conveyor belt wall panels 103 are reinforced by connecting round and square steel bars. One end of the first rotating shaft 201 is connected to an external power unit (servo motor) to provide power for the rotation of the first rotating shaft 201. The external power unit drives the first rotating shaft 201 to rotate, and the large hub wheel 202 starts to rotate under the drive of the first rotating shaft 201. The external conveyor belt orderly transports the paper bags to one side of the arc-shaped mounting plate 202b of the large hub wheel 202. The paper bags are adhered to the arc-shaped mounting plate 202b and transported by the large hub wheel. When the rotating shaft 201 rotates, the hub gear 203 is also driven to rotate. The hub gear 203 sequentially drives the first transmission assembly 204 and the second transmission assembly 205. Under the drive of the hub gear 203, the first transmission assembly 204 and the second transmission assembly 205 drive the first upper conveyor belt assembly 301, the second upper conveyor belt assembly 302, and the lower conveyor belt assembly 303. The paper bags on the outer wall of the arc-shaped mounting plate 202b are orderly clamped and transported by the first upper conveyor belt assembly 301 and the lower conveyor belt assembly 303. The paper bag is then transported by the second upper conveyor belt assembly 302 and the lower conveyor belt assembly 303. As the paper bag passes between the first upper conveyor belt assembly 301 and the second upper conveyor belt assembly 302, the high-speed camera 404 detects the paper bag. If the paper bag is found to be defective, a signal is sent to the PLC controller. The PLC controller sends a signal to the solenoid valve connected to the high-speed cylinder 401, which opens the solenoid valve to control the extension rod end of the high-speed cylinder 401 to extend and push the swing arm 403. The swing arm 403 then drives the rejection support 402 to rotate, causing the rejection plate 402a to rise, so that the defective paper bag passes under the rejection plate 402a. After receiving the signal sent by the high-speed camera 404, the PLC controller can adjust the time of sending the signal to the solenoid valve connected to the high-speed cylinder 401 according to the speed of the paper bag transportation, so that the defective paper bag can pass under the rejection support 402 just when it rotates. The control of the PLC controller is a common technique used by those skilled in the art.

[0026] In this embodiment, the first transmission assembly 204 includes a bag-discharging hub swing arm 204a respectively disposed on the outer wall of two main unit wall panels 102. A second rotating shaft 204b is fixed between the two bag-discharging hub swing arms 204a. The second rotating shaft 204b is rotatably connected to the two main unit wall panels 102. One end of the second rotating shaft 204b passes through the bag-discharging hub swing arm 204a and is rotatably provided with a first transmission gear 204c. A first transition gear 204d is rotatably provided in the middle of the bag-discharging hub swing arm 204a. A bag-discharging hub gear 204e is provided on the outer side of 204a. A third rotating shaft 204f is rotatably provided between the two bag-discharging hub swing arms 204a. A bag-discharging hub 204g is provided on the outer wall of the third rotating shaft 204f. One end of the third rotating shaft 204f passes through the bag-discharging hub swing arm 204a and is fixedly connected to the bag-discharging hub gear 204e. The first transition gear 204d meshes with the first transmission gear 204c and the bag-discharging hub gear 204e on both sides respectively. The first transmission gear 204c meshes with the large hub gear 203.

[0027] When the large hub gear 203 rotates, it can drive the first transmission gear 204c to rotate. The first transmission gear 204c drives the bag outlet hub gear 204e to rotate through the first transition gear 204d. When the bag outlet hub gear 204e rotates, it drives the bag outlet hub 204g to rotate through the third rotating shaft 204f.

[0028] In this embodiment, cylinder seats 204h are respectively provided on the side walls of the two main unit wall panels 102. The top of the cylinder seat 204h is rotatably connected to the bottom of the cylinder 204i, and the end of the telescopic rod of the cylinder 204i is rotatably connected to the bottom of one side of the bag outlet hub swing arm 204a.

[0029] When the telescopic rod of the control cylinder 204i extends or retracts, the telescopic rod of the cylinder 204i can drive the bag outlet hub swing arm 204a to rotate around the second rotating shaft 204b as the center. When the telescopic rod of the cylinder 204i retracts, it can drive the bag outlet hub swing arm 204a to rotate counterclockwise around the second rotating shaft 204b as the center. The bag outlet hub swing arm 204a drives the bag outlet hub 204g to rotate around the second rotating shaft 204b as the center, thereby making the bag outlet hub 204g move away from the large hub wheel 202, which makes it easier for maintenance personnel to clean the paper bags blocking the opening between the first upper conveyor belt assembly 301 and the lower conveyor belt assembly 303.

[0030] In this embodiment, the second transmission component 205 includes a mounting plate 205a fixed to the outer wall of the main unit wall panel 102. A second transition gear 205b and a third transition gear 205c are rotatably mounted on the mounting plate 205a. A second transmission gear 205d is provided on one side of the second transition gear 205b. A rotating column 205e is provided on the back of the second transmission gear 205d. One end of the rotating column 205e passes through the mounting plate 205a and is provided with a drive sprocket 205f. The outer wall of the rotating column 205e is rotatably connected to the mounting plate 205a. The two sides of the second transition gear 205b are respectively engaged with the first transmission gear 204c and the third transition gear 205c. The third transition gear 205c is engaged with the second transmission gear 205d.

[0031] When the first transmission gear 204c rotates, it drives the second transition gear 205b to rotate. The second transition gear 205b then drives the second transmission gear 205d to rotate through the third transition gear 205c. Since the second transmission gear 205d has a rotating column 205e on its back and the outer wall of the rotating column 205e is rotatably connected to the mounting plate 205a, the second transmission gear 205d drives the drive sprocket 205f to rotate through the rotating column 205e.

[0032] In this embodiment, a transition sprocket 205g is provided in the middle of the conveyor belt wall plate 103, and a tensioning sprocket 205h and a passive sprocket 205i are provided on both sides of the conveyor belt wall plate 103 respectively. The driving sprocket 205f, the transition sprocket 205g, the tensioning sprocket 205h and the passive sprocket 205i are connected by a transmission chain 205j.

[0033] When the drive sprocket 205f rotates, it drives the transition sprocket 205g, tension sprocket 205h and driven sprocket 205i to rotate through the transmission chain 205j.

[0034] In this embodiment, the belt conveyor component 300 includes a fourth rotating shaft 304 disposed on the back of the driven sprocket 205i. The outer wall of the fourth rotating shaft 304 is rotatably connected to two conveyor belt wall plates 103. A lower belt roller 304a is disposed on the outer wall of the fourth rotating shaft 304. A lower belt roller gear 304b is disposed on one side of the fourth rotating shaft 304. A fifth rotating shaft 305 is disposed above the fourth rotating shaft 304. Both ends of the fifth rotating shaft 305 are rotatably connected to the two conveyor belt wall plates 103. An upper belt roller 305a is disposed on the outer wall of the fifth rotating shaft 305. An upper belt roller gear 305b is disposed on one side of the fifth rotating shaft 305. The upper belt roller gear 305b meshes with the lower belt roller gear 304b. A [missing information - likely a device or mechanism] is disposed below the conveyor belt wall plate 103. An inner transition gear 306 meshes with the lower belt roller gear 304b. A sixth rotating shaft 307 and a seventh rotating shaft 308 are respectively provided on one side of the inner transition gear 306 and are rotatably connected between the two conveyor belt wall plates 103. An air suction roller 307a is provided on the outer wall of the sixth rotating shaft 307. Two air suction roller gears 307b are arranged at intervals on one side of the sixth rotating shaft 307. One of the air suction roller gears 307b meshes with the inner transition gear 306. Two pressure rollers 308a are arranged at intervals in the middle of the seventh rotating shaft 308. An upper pressure roller gear 308b is provided on one side of the seventh rotating shaft 308. The upper pressure roller gear 308b meshes with the other air suction roller gear 307b. The two pressure rollers 308a are in close contact with the surface of the air suction roller 307a.

[0035] When the driven sprocket 205i rotates, it drives the fourth shaft 304 to rotate, which in turn drives the lower belt roller 304a and the lower belt roller gear 304b to rotate. The lower belt roller gear 304b meshes with the upper belt roller gear 305b and the inner transition gear 306, respectively. Therefore, the lower belt roller gear 304b drives the upper belt roller 305a to rotate, and when the inner transition gear 306 rotates, it drives one of the suction roller gears 307b to rotate. The suction roller gear 307b drives the suction roller 307a and the other suction roller gear 307b to rotate, and the other suction roller gear 307b... The roller gear 307b drives the two pressure rollers 308a to rotate through the upper pressure roller gear 308b. The outer wall of the suction roller 307a is evenly distributed with suction holes, and the suction roller 307a is connected to an external suction device (such as a vacuum pump). The external suction device is electrically connected to the PLC controller. When the external suction device evacuates the inside of the suction roller 307a under the control of the PLC controller, the paper bag is adsorbed on the outer wall of the suction roller 307a when it is transported to the suction roller 307a. When the paper bag passes to the bottom of the two pressure rollers 308a, the two pressure rollers 308a roll and abut against the outer wall of the suction roller 307a.

[0036] In this embodiment, the lower conveyor belt assembly 303 includes an eighth rotating shaft 303a and a ninth rotating shaft 303b disposed on one side of the bag outlet hub 204g and between the two main machine wall plates 102. A conveying roller 303c, a guide roller 303d, and an intermediate conveying roller 303e are rotatably disposed between the two main machine wall plates 102. Three fixed guide wheels 303f are spaced apart on the outer wall of the eighth rotating shaft 303a. Two paddles 303g are disposed in the gap between the three fixed guide wheels 303f. The top of the paddles 303g can be inserted into the slide groove 202a. Three movable guide wheels are spaced apart on the ninth rotating shaft 303b. The two conveying... Three lower guide rollers 303i are rotatably arranged between the wall panels 103. The tenth rotating shaft 303j and the eleventh rotating shaft 303k are respectively arranged on both sides of the three lower guide rollers 303i. Three movable guide wheels are arranged at intervals on the outer walls of the tenth rotating shaft 303j and the eleventh rotating shaft 303k. Three lower belts 303l are sequentially wrapped between the fixed guide wheel 303f, the conveyor roller 303c, the guide roller 303d, the intermediate conveyor roller 303e, the three lower guide rollers 303i, the lower belt roller 304a, the three movable guide wheels on the tenth rotating shaft 303j and the eleventh rotating shaft 303k, and the three movable guide wheels on the ninth rotating shaft 303b.

[0037] When the lower belt roller 304a rotates, it can drive the rotation of three lower belts 303l. The rotation of the three lower belts 303l can be used to transport paper bags. When the hub wheel 202 rotates, the arc-shaped mounting plate 202b rotates accordingly. As the arc-shaped mounting plate 202b rotates, the paddle 303g is inserted into the two sliding grooves 202a of the arc-shaped mounting plate 202b, separating the paper bag from the arc-shaped mounting plate 202b and allowing it to enter the opening between the lower conveyor belt assembly 303 and the first upper conveyor belt assembly 301 for the next step of transportation.

[0038] In this embodiment, the first upper conveyor belt assembly 301 includes an intermediate guide roller 301a and a first upper guide roller 301b rotatably disposed between two conveyor belt wall plates 103. One end of the first upper guide roller 301b passes through the conveyor belt wall plate 103 and is connected to the back of the transition sprocket 205g. The first upper conveyor belt 301c sequentially wraps around the bag outlet hub 204g, the conveyor roller 303c, the guide roller 303d, the intermediate conveyor roller 303e, the first upper guide roller 301b, and the intermediate guide roller 301a. The first upper conveyor belt 301c and the three lower belts 303l are in contact with each other on the outer walls of the conveyor roller 303c, the guide roller 303d, and the intermediate conveyor roller 303e.

[0039] When the transition sprocket 205g rotates, it drives the first upper guide roller 301b to rotate. The first upper conveyor belt 301c is driven to rotate by the bag outlet hub 204g and the first upper guide roller 301b. The paper bag is clamped and transported by the first upper conveyor belt 301c and three lower belts 303l.

[0040] In this embodiment, the second upper conveyor belt assembly 302 includes a second upper guide roller 302a rotatably disposed between two conveyor belt wall plates 103, a pressure roller 302b disposed between the second upper guide roller 302a and the upper belt roller 305a, and a second upper conveyor belt 302c enveloping the second upper guide roller 302a, the pressure roller 302b and the upper belt roller 305a. The second upper conveyor belt 302c and three lower belts 303l are in contact with each other on the outer wall of the pressure roller 302b.

[0041] When the upper belt roller 305a rotates, it drives the second upper conveyor belt 302c to rotate, and the paper bag can be transported by the clamping of the second upper conveyor belt 302c and the three lower belts 303l.

[0042] In this embodiment, the automatic waste rejection component 400 also includes a support between the suction roller 307a and the lower belt roller 304a. A guide plate 405 is provided at the top of the support. A limit block 402b is provided at one end of the waste rejection support 402. A stop block 406 is provided on the inner wall of the conveyor belt wall plate 103. The side of the waste rejection plate 402a near the suction roller 307a is inclined.

[0043] After the paper bag comes out from the opening between the second upper conveyor belt 302c and the three lower belts 303l, it is transported to the guide plate 405, and then transported to the outer wall of the suction roller 307a via the guide plate 405. The side of the waste removal plate 402a near the suction roller 307a is set in an inclined shape to facilitate the transport of the paper bag to the top of the waste removal plate 402a.

[0044] Working principle: The conveyor belt wall panels 103 are reinforced by connecting round and square steel bars. One end of the first rotating shaft 201 is connected to an external power device (such as a servo motor) to provide power for the rotation of the first rotating shaft 201. The external power device drives the first rotating shaft 201 to rotate, and the large hub wheel 202 starts to rotate under the drive of the first rotating shaft 201. When the first rotating shaft 201 rotates, the large hub gear 203 is also driven to rotate. When the large hub gear 203 rotates, it can drive the first transmission gear 204c to rotate. The first transmission gear 204c drives the bag outlet hub gear 204e to rotate through the first transition gear 204d. When the bag outlet hub gear 204e rotates, it drives the bag outlet hub 204g to rotate through the third rotating shaft 204f. The rotation of the bag outlet hub 204g can drive the bag outlet hub 204g to rotate. The first upper conveyor belt 301c rotates, and the first transmission gear 204c rotates, driving the second transition gear 205b to rotate. The second transition gear 205b then drives the second transmission gear 205d to rotate via the third transition gear 205c. Since the second transmission gear 205d has a rotating column 205e on its back, and the outer wall of the rotating column 205e is rotatably connected to the mounting plate 205a, the second transmission gear 205d drives the drive sprocket 205f to rotate via the rotating column 205e. When the drive sprocket 205f rotates, it drives the transition sprocket 205g, the tensioning sprocket 205h, and the driven sprocket 205i to rotate via the transmission chain 205j. When the transition sprocket 205g rotates, it drives the first upper guide roller 301b to rotate. The upper conveyor belt 301c is driven to rotate simultaneously by the bag outlet hub 204g and the first upper guide roller 301b. When the driven sprocket 205i rotates, it drives the fourth rotating shaft 304 to rotate, which in turn drives the lower belt roller 304a and the lower belt roller gear 304b to rotate. The lower belt roller gear 304b meshes with the upper belt roller gear 305b and the inner transition gear 306, respectively. Therefore, the lower belt roller gear 304b drives the upper belt roller 305a to rotate. When the upper belt roller 305a rotates, it can provide driving force for the rotation of the second upper conveyor belt 302c. When the lower belt roller 304a rotates, it can drive the rotation of the three lower belts 303l. Therefore, when the first rotating shaft 201 rotates, it can simultaneously drive the first upper conveyor belt assembly 301 and the second upper conveyor belt assembly 302c. When the inner transition gear 306 rotates, it drives one of the suction roller gears 307b to rotate. The suction roller gear 307b drives the suction roller 307a and the other suction roller gear 307b to rotate. The other suction roller gear 307b drives the two pressure rollers 308a to rotate through the upper pressure roller gear 308b. Therefore, when the first rotating shaft 201 rotates, it can also drive the suction roller 307a and the two pressure rollers 308a to rotate. The outer conveyor belt transports the paper bags in an orderly manner to one side of the arc-shaped mounting plate 202b of the large hub wheel 202. The paper bags are adhered to the arc-shaped mounting plate 202b and transported by the large hub wheel. When the large hub wheel 202 rotates, the arc-shaped mounting plate 202b rotates accordingly. As the arc-shaped mounting plate 202b rotates,The pry bar 303g is inserted into the two grooves 202a of the arc-shaped mounting plate 202b, disengaging the paper bag from the arc-shaped mounting plate 202b and allowing it to enter the opening between the three lower conveyor belts 303l and the first upper conveyor belt 301c. The paper bag is then clamped and transported by the three lower conveyor belts 303l and the first upper conveyor belt 301c. Next, the paper bag is clamped and transported by the second upper conveyor belt 302c and the three lower conveyor belts 303l to the guide plate 405. After passing through the guide plate 405, it is clamped and rotated by the outer wall of the suction roller 307a and the two pressure rollers 308a, transported to the top of the waste removal plate 402a, and then ejected. The paper bag collection bag on one side of the waste removal plate 402a is packaged. If the paper bag is damaged or otherwise unqualified, a high-speed camera 404 detects the paper bag as it passes between the first upper conveyor belt 301c and the second upper conveyor belt 302c. If the paper bag is found to be unqualified, a signal is sent to the PLC controller. The PLC controller then sends a signal to the solenoid valve connected to the high-speed cylinder 401. The solenoid valve opens, controlling the extension rod end of the high-speed cylinder 401 to extend and push the swing arm 403. The swing arm 403 then drives the waste removal support 402 to rotate, raising one side of the waste removal plate 402a, thus... After the paper bag is conveyed from the suction roller 307a, it cannot be thrown out from the top of the rejection support 402. Simultaneously, an external suction device (such as a vacuum pump) evacuates the inside of the suction roller 307a under the control of the PLC controller. When the paper bag reaches the suction roller 307a, it is adhered to the outer wall of the roller. As the paper bag passes the bottom of the two pressure rollers 308a, they roll and press against the outer wall of the suction roller 307a until the paper bag is rotated to one side of the suction roller 307a. At this point, the PLC controller stops the external suction device from evacuating the paper bag. The bag will no longer be adhered to the outer wall of the suction roller 307a and will fall under gravity. The operator can adjust the PLC controller so that, upon receiving the signal from the high-speed camera 404, the PLC controller can adjust the timing of sending signals to the solenoid valve connected to the high-speed cylinder 401 and to the external suction device based on the speed of the paper bag transport. This prevents defective paper bags from being transported to the top of the rejection plate 402a and from being ejected. Furthermore, when the bag reaches one side of the suction roller 307a, the vacuuming operation on the suction roller 307a is stopped, causing the paper bag to fall under gravity.
