Description

Technical Field

[0001] This invention relates to the field of packaging feeding technology, and more specifically to a packaging feeding device for block sugars. Background Technology

[0002] During the cutting, drying, and transportation of block sugars, foreign objects such as metal, stones, hard plastics, and ceramics may be mixed in. Therefore, X-ray foreign object detection equipment is required after bagging and before boxing to identify foreign objects inside the plastic packaging bags or block sugars. When an abnormal signal is detected, the existing equipment usually issues an alarm, and the operator manually picks out the bagged products suspected of containing foreign objects and places them in an abnormal box. If the X-ray foreign object detection equipment does not detect any abnormalities, the operator manually weighs the bagged products. After the weight is qualified, the bagged products are manually placed into the material conveyor trough of the cartoning machine. After entering the material conveyor trough of the cartoning machine, the bagged products are accurately conveyed to the cartoning station by the conveyor belt, and the pushing mechanism pushes the bagged products into the packaging box. If the weight of the bagged products is less than the standard weight, the operator manually picks them out and places them in an unqualified box.

[0003] Chinese patent CN220690831U discloses an X-ray foreign object detector that uses an X-ray foreign object detector to detect impurities in products; however, the aforementioned equipment cannot automatically remove products from the production line when an abnormality is detected, nor can it automatically load products when no abnormality is detected.

[0036] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0038] like Figure 1-2As shown, the present invention provides a feeding device for packaging block sugars, including an X-ray foreign object detector and a feeding unit 2 located on the input side of the X-ray foreign object detector. The feeding unit 2 is used to transfer bagged products from the ground to the input side of the X-ray foreign object detector. The output side of the X-ray foreign object detector is provided with a weighing roller conveyor 3 and a transfer unpacking robot arm 4. The weighing roller conveyor 3 is used to weigh the bagged products after the X-ray foreign object detector. The execution end of the transfer unpacking robot arm 4 is provided with a transfer unpacking mechanism 5, and the side of the transfer unpacking robot arm 4 is provided with a block sugar separation unit 6. The transfer unpacking mechanism 5 is used to transfer qualified bagged products to the material conveying trough of the cartoning machine. For abnormal bagged products, they are transferred to the block sugar separation unit 6 for unpacking and unloading. The block sugar separation unit 6 is used to detect the block sugars in the bagged products one by one and separate the block sugars containing foreign objects from the normal block sugars.

[0039] Foreign matter is scanned by an X-ray foreign object detector; the bagged product continues to the weighing roller conveyor 3, where the transfer unpacking robot arm 4 drives the transfer unpacking mechanism 5 to pick up the bagged product containing foreign matter and transfer it above the block sugar separation unit 6. The transfer unpacking mechanism 5 opens the bagged product; the block sugar separation unit 6 inspects each block sugar individually, separating abnormal block sugar containing foreign matter from normal block sugar; when the X-ray foreign object detector does not detect any abnormalities and the weighing roller conveyor 3 shows that the weight is qualified, the bagged product is directly transferred by the transfer unpacking robot arm 4 to the material conveying trough of the cartoning machine to enter the subsequent cartoning process; using the transfer unpacking robot arm 4 and its execution end transfer unpacking mechanism 5, the bagged product can be automatically diverted to different processing paths according to the detection results, replacing manual sorting; the block sugar separation unit 6 inspects and separates each block sugar in the abnormal bagged product, and can remove only individual block sugar containing foreign matter while retaining normal block sugar.

[0040] like Figure 3-4 As shown, the transfer bag-opening mechanism 5 includes a transfer bag-opening base plate 8 connected to the execution end of the transfer bag-opening robotic arm 4. One side of the transfer bag-opening base plate 8 is connected to the first clamping assembly 10 via a connecting post 9, and the other side of the transfer bag-opening base plate 8 is rotatably connected to two bag-opening swing arms 11. One end of the bag-opening swing arm 11 is rotatably engaged with the transfer bag-opening base plate 8 via a bag-opening swing shaft 12. A bag-opening motor 13 is fixed to the upper side of the transfer bag-opening base plate 8 via a motor bracket. The motor shaft of the bag-opening motor 13 is fixed to the bag-opening swing shaft 12 via a coupling. The bag-opening motor 13 can drive the bag-opening swing arm 11 to rotate. The other ends of the two bag-opening swing arms 11 are respectively provided with bag-opening push rods 14. The push head of the bag-opening push rod 14 extends downward from the bag-opening swing arm 11 and is connected to the second clamping assembly 15 and the third clamping assembly 16 respectively. The first clamping assembly 10, the second clamping assembly 15, and the third clamping assembly 16 have the same structure and are used to clamp the sealing end of the bagged product.

[0041] like Figure 5-6 As shown, the working process of the transfer and unpacking mechanism 5 is as follows: The transfer and unpacking robotic arm 4 moves the transfer and unpacking mechanism 5 to both sides of the bagged product, so that the first clamping component 10, the second clamping component 15, and the third clamping component 16 are respectively aligned with the seal of the bagged product to clamp it; if the bagged product passes the X-ray foreign object detection machine, the transfer and unpacking robotic arm 4 directly transfers it to the material conveying trough of the cartoning machine, and the three clamping components are released to complete the feeding; if the bagged product is abnormal after the X-ray foreign object detection machine, the transfer and unpacking robotic arm 4 first transfers it to the top of the block sugar separation unit 6; the unpacking push rod 14 drives the second clamping component 15 and the third clamping component 16 to move in opposite directions. The direction of movement (one upward and one downward) pulls open the sealed part of the bagged product to form an opening; the unpacking motor 13 starts, driving the unpacking swing arm 11 to rotate around the unpacking swing shaft 12, which drives the second clamping component 15 and the third clamping component 16 to swing outward respectively, further pulling open the opening of the bagged product, allowing the block sugar to fall into the block sugar separation unit 6; by setting the unpacking push rod 14 and the unpacking swing arm 11 in a two-stage bag opening action, the unpacking push rod 14 first drives the second and third clamping components 16 to move in opposite directions in a straight line to achieve the initial tearing of the seal; then the unpacking motor 13 drives the unpacking swing arm 11 to swing outward to achieve the secondary expansion of the opening.

[0042] like Figure 18 As shown, the first clamping assembly 10 includes a clamping base 17. A clamping motor 18 is mounted on the upper side of the clamping base 17 via a motor bracket. The motor shaft of the clamping motor 18 is connected to one end of a first clamping screw 19. The other end of the first clamping screw 19 extends downward from the clamping base 17 and is fixed to one end of a second clamping screw 20 via a coupling. The other end of the second clamping screw 20 is rotatably engaged with the lower side of the clamping base 17 via a bearing. Two clamping plates 21 with Z-shaped cross sections are provided opposite to each other inside the clamping base 17. One clamping plate 21 is threadedly engaged with the first clamping screw 19, and the other clamping plate 21 is threadedly engaged with the second clamping screw 20. The first clamping screw 19 and the second clamping screw 20 rotate in opposite directions. The clamping surface of the clamping plate 21 is provided with a clamping pad 22 to increase friction. The clamping pad 22 has a clamping ridge 7 on the contact side with the bagged product. The clamping motor 18 drives the first clamping screw 19 to rotate. The first clamping screw 19 drives the second clamping screw 20 to rotate in opposite directions through a coupling. This causes the two clamping plates 21, which are threadedly engaged with the two screws, to move synchronously in opposite directions. Since the two screws rotate in opposite directions, the two clamping plates 21 move closer together or open in opposite directions when the screws rotate, thereby centering and clamping or releasing the bagged product.

[0043] like Figure 7-8As shown, the block sugar separation unit 6 includes a vibrating plate 23 and a small X-ray foreign object detector located on the output side of the vibrating plate 23. A belt conveyor platform 25 is provided on the output side of the small X-ray foreign object detector. A separation push rod 26 is fixed to one side of the belt conveyor platform 25 via a push rod seat. The push head of the separation push rod 26 passes through the push rod seat and is fixed to a separation push plate 27. A first support platform 28 is provided on the opposite side of the separation push rod 26, and an abnormal block sugar collection box 29 is provided on the first support platform 28. When the small X-ray foreign object detector detects… After detecting abnormal lumpy sugars, the abnormal lumpy sugars move to the corresponding position on the separating push plate 27, and the separating push rod 26 extends to push the abnormal lumpy sugars into the abnormal lumpy sugar collection box 29; the output side of the belt conveyor platform 25 is provided with a second support platform 30, on which a normal lumpy sugar collection box 31 is placed; the other side of the vibrating plate 23 is provided with a packaging collection bin 32, and through the cooperation of the transfer unpacking robot arm 4 and the transfer unpacking mechanism 5, the unpacked plastic packaging is placed in the packaging collection bin 32.

[0044] In this solution, after the transfer and unpacking mechanism 5 fully opens the opening of the abnormally bagged product, the lumpy sugar pieces fall into the vibrating plate 23. The transfer and unpacking robotic arm 4 and the transfer and unpacking mechanism 5 transfer the unpacked empty plastic bags to the packaging collection bin 32 on the other side of the vibrating plate 23. The vibrating plate 23 arranges the scattered lumpy sugar pieces in an orderly manner through vibration and transports them one by one to the small X-ray foreign object detector. The small X-ray foreign object detector scans each lumpy sugar piece in real time to determine whether it contains foreign objects such as metal, stones, hard plastic, or ceramics. When a lumpy sugar piece is detected as normal, that piece... The lumpy sugars continue forward into the conveyor belt platform 25 and eventually fall into the normal lumpy sugar collection box 31 on the output side, awaiting subsequent repackaging. When the small X-ray foreign object detector detects a foreign object in a lumpy sugar, the lumpy sugar moves to the corresponding position of the separating push plate 27, and the separating push rod 26 extends instantly, driving the separating push plate 27 to push the abnormal lumpy sugar laterally out of the conveyor belt platform 25, so that it falls into the abnormal lumpy sugar collection box 29 on the opposite side. By setting the vibrating plate 23 to transport the lumpy sugars in a single row, it is ensured that the lumpy sugars enter the small X-ray foreign object detector at intervals.

[0045] Weighing roller conveyor 3 is used to detect the weight of bagged products. When the weight of the bagged products is less than the standard weight, the current practice is to replenish the product with block sugars after it leaves the production line; for example... Figure 9As shown, this application proposes an online replenishment method for block sugars; a rectangular replenishment port 33 is provided on the transfer and unpacking substrate 8, and a replenishment cavity 34 is provided on the replenishment port 33 to accommodate small packages of block sugars; a replenishment push rod 35 is provided on the upper side of the replenishment cavity 34, and the push head of the replenishment push rod 35 extends into the replenishment cavity 34 and is fixed to a replenishment push plate 36, which is used to press the small packages of block sugars downward; a hemispherical rubber locking protrusion 37 is provided in the replenishment port 33 to prevent the small packages of block sugars from falling off automatically; in this solution, when the bagged product is inspected by an X-ray foreign object detector and no abnormalities are found... Then it enters the weighing roller conveyor 3. If the weighing roller conveyor 3 detects that the weight of the bagged product is less than the standard weight, the transfer unpacking robot arm 4 drives the execution end to approach the bagged product. The first clamping component 10 clamps and transfers the bagged product. The transfer unpacking robot arm 4 transfers the replenished bagged product to the material conveying trough of the cartoning machine. The replenishment push rod 35 is activated, and its push head drives the replenishment push plate 36 to move downward, pushing the small packaged block sugar that has been placed in the replenishment cavity 34 downward. The small packaged block sugar overcomes the elastic resistance of the rubber protrusion 37 and falls into the material conveying trough of the cartoning machine through the replenishment port 33, completing the online automatic replenishment.

[0046] The feeding unit 2 is used to transfer bagged products from the ground to the input side of the X-ray foreign object detection machine, such as... Figure 10 As shown, the feeding unit 2 includes an inclined belt conveyor 38 and a centering mechanism 39 located on the discharge side of the inclined belt conveyor 38. It also includes a detection feeding mechanism 40 located above the centering mechanism 39. The inclined belt conveyor 38 transports the packaged bagged products from the ground to the centering mechanism 39. After the centering mechanism 39 corrects the bagged products, the detection feeding mechanism 40 transfers the corrected bagged products to the input side of the X-ray foreign object detector. Figure 11 As shown, the centering mechanism 39 includes a centering conveyor roller 41 with a drive source. Centering push rods 42 are provided on both sides of the centering conveyor roller 41. The push head of the centering push rod 42 extends into the inner side of the centering conveyor roller 41 and is fixed to the centering push plate 43. Air spray fixing plates 44 are provided on both sides of the centering conveyor roller 41. Air spray splitting heads 45 are provided on the air spray fixing plates 44. The main pipeline of the splitting head is used to connect to the high-pressure air source in the factory. The branch pipeline of the splitting head is connected to the air spray nozzle 47 through the air spray corrugated pipe 46. The outer packaging of the bagged product is cleaned by air spraying through the air spray nozzle 47 before centering.

[0047] like Figure 11 As shown, most of the bagged products conveyed by the inclined belt conveyor 38 are placed horizontally, with a small portion placed vertically. The transfer and unpacking mechanism 5 needs to maintain the consistency of the materials. To solve this problem, such as... Figure 12As shown, floating centering shafts 48 are slidably fitted on both sides of the centering push plate 43. One end of the floating centering shaft 48 has an anti-detachment structure, and the other end of the floating centering shaft 48 is provided with a floating push plate 49. A floating centering spring 50 is sleeved on the floating centering shaft 48 and is locked between the centering push plate 43 and the floating push plate 49. A laser rangefinder sensor 52 is fixed to the side of the centering push plate 43 through a sensor bracket 51. The laser rangefinder sensor 52 is aligned with the end of the floating centering shaft 48. When the bagged product moves between the floating push plates 49, the centering push rod 42 extends, and the floating push plate 49 contacts the side of the bagged product. The alignment process is as follows: After elongation, the distance between the floating push plates 49 is less than the width of the bagged product when it is placed vertically. The floating push plates 49 will squeeze the floating centering spring 50, and the floating centering axis 48 will slide along the centering push plate 43. When the bagged product is placed horizontally (wider), the floating centering axis 48 moves a longer distance, and the laser range sensor 52 detects that the floating centering axis 48 is closer. When the bagged product is placed vertically (narrower), the floating centering axis 48 moves a shorter distance, and the laser range sensor 52 detects that the floating centering axis 48 is farther away. This allows the system to determine whether the bagged product is placed horizontally or vertically during centering.

[0048] like Figure 13-14 As shown, the detection and feeding mechanism 40 includes a detection and feeding base frame 53. One end of the detection and feeding base frame 53 is fixed to the side of the X-ray foreign object detector via an ear plate 54, and the other end of the detection and feeding base frame 53 is fixed to the side of the centering conveyor roller conveyor 41 via a support plate 55. A detection and feeding motor 56 is provided on the side of the detection and feeding base frame 53. The motor shaft of the detection and feeding motor 56 extends to the inside of the detection and feeding base frame 53 and is fixed to one end of the detection and feeding screw 57 via a coupling. The other end of the detection and feeding screw 57 is rotatably engaged with the end of the detection and feeding base frame 53 via a bearing. A transfer guide block 58 is threaded onto the detection and feeding screw 57, such as... Figure 15 As shown, the transfer guide block 58 is rotatably fitted with a flip guide shaft 59 via a bearing. The inner side of the flip guide shaft 59 is fixed to the adsorption assembly 61; the outer side of the flip guide shaft 59 is fixedly connected to one end of the flip swing plate 62, and the other end of the flip swing plate 62 is rotatably fitted with a flip guide wheel 63; as shown Figure 16As shown, a straight guide groove 64 is horizontally opened through the side of the detection and feeding base frame 53, and the flipping guide wheel 63 forms a rolling pair with the straight guide groove 64; a zigzag guide groove 65 is opened on the lower side of the straight guide groove 64, and the horizontal end of the zigzag guide groove 65 is parallel to the straight guide groove 64; a flipping switching drive groove 66 is opened on the upper side of the straight guide groove 64 corresponding to the position of the zigzag guide groove 65; a flipping switching cylinder 67 is fixed on the detection and feeding base frame 53 by a mounting plate 60, and the telescopic end of the flipping switching cylinder 67 is fixedly connected to the angle steel connecting plate 68; triangular first pads 69 and rectangular second pads 70 are arranged at intervals on the angle steel connecting plate 68, and both the first pads 69 and the second pads 70 are connected to the flipping... The switching drive groove 66 is slidably engaged, and a horizontal slide is formed between the first pad 69 and the second pad 70, corresponding to the width of the straight guide groove 64. When the flip switching cylinder 67 extends, the first pad 69 and the second pad 70 slide downward along the flip switching drive groove 66, and the second pad 70 fits against the inclined surface of the zigzag guide groove 65, forming a horizontal slide between the first pad 69 and the second pad 70. This horizontal slide is connected to the straight guide groove 64, forming a straight guide slide. When the flip switching cylinder 67 retracts, the first pad 69 and the second pad 70 slide upward along the flip switching drive groove 66. The lower inclined surface of the second pad 70 is in contact with the upper inclined surface of the zigzag guide groove 65.

[0049] Adsorption component 61 is used to adsorb the bagged product after alignment, such as Figure 14 As shown, the adsorption assembly 61 includes a flip angle steel 71 fixed to the flip guide shaft 59. A first adsorption push rod 72 is fixed to the upper side of the flip angle steel 71. The push head of the first adsorption push rod 72 passes through the flip angle steel 71 and is fixed to the connecting ear plate 73. A connecting beam 74 is provided between the two connecting ear plates 73. A second adsorption push rod 75 is vertically provided on the connecting beam 74. The push head of the second adsorption push rod 75 passes downward through the connecting beam 74 and is fixed to the upper side of the adsorption frame 76. A pneumatic suction cup 77 is provided on the lower side of the adsorption frame 76. The pneumatic suction cup 77 is used to adsorb bagged products.

[0050] like Figure 16-17As shown, in this scheme, the inclined belt conveyor 38 transports the bagged products from the ground upwards to the centering conveyor roller conveyor 41; before entering the centering area, the air nozzles 47 clean the outer packaging of the bagged products with high-pressure airflow; subsequently, the centering conveyor roller conveyor 41 transports the bagged products between the two floating push plates 49; the centering push rod 42 is activated, pushing the centering push plate 43 and the floating push plate 49 to move towards the center, and the floating push plate 49 contacts the side of the bagged products; the floating push plate 49 will squeeze the floating centering spring 50, and the floating centering shaft 48 will move along the centering push plate 43. Sliding: When the bagged product is placed vertically, the floating center axis 48 moves a shorter distance, and the sensor detects a longer distance; when the bagged product is placed horizontally, the floating center axis 48 moves a longer distance, and the sensor detects a shorter distance; the system judges the posture of the bagged product accordingly; after centering, the adsorption component 61 performs a material picking action, the second adsorption push rod 75 extends, driving the adsorption frame 76 and the pneumatic suction cup 77 to descend to the upper surface of the bagged product, and the pneumatic suction cup 77 starts adsorbing the bagged product; then the second adsorption push rod 75 retracts, lifting the bagged product;

[0051] If the bagged product is placed horizontally, the flipping switching cylinder 67 remains extended, and the horizontal slide formed between the first pad 69 and the second pad 70 connects with the straight guide groove 64 to form a straight guide slide. The detection and feeding motor 56 drives the detection and feeding screw 57 to rotate, which drives the transfer guide block 58 to move along the detection and feeding base frame 53. The flipping guide wheel 63 rolls horizontally along the straight guide slide. The adsorption component 61 moves the bagged product horizontally to the upper side of the X-ray foreign object detector input side. The first adsorption push rod 72 extends to lower the bagged product onto the conveyor belt. The pneumatic suction cup 77 is released, completing the feeding.

[0052] If the bagged product is placed vertically, the flip-changing cylinder 67 retracts, and the first pad 69 and the second pad 70 slide upward. The lower inclined surface of the second pad 70 connects with the upper inclined surface of the zigzag guide groove 65, forming a downward-sloping guide path. When the transfer guide block 58 moves to the position of the flip-changing drive groove 66, the flip guide wheel 63 enters the zigzag guide groove 65 and rolls downward along the inclined surface, causing the flip swing plate 62 to swing downward. The flip guide shaft 59 rotates accordingly, causing the adsorption component 61 to rotate 90 degrees around the flip guide shaft 59, flipping the vertically adsorbed bagged product to a horizontal position. Then the guide wheel enters the horizontal section of the zigzag guide groove 65, and the detection feeding motor 56 continues to drive the transfer guide block 58 to move horizontally, transferring the flipped horizontal bagged product to the upper part of the input side of the X-ray foreign object detector. Similarly, the first adsorption push rod 72 descends and the pneumatic suction cup 77 releases to complete the feeding.

[0053] The flip-change cylinder 67 drives the first pad 69 and the second pad 70 to rise and fall within the flip-change drive groove 66. In conjunction with the switching between the straight guide groove 64 and the zigzag guide groove 65, two motion modes are realized: horizontal conveying of the adsorption component 61 and 90-degree flip feeding. When flipping is required, the guide wheel automatically enters the zigzag guide groove 65 to complete the flipping, without the need for an additional independent flip drive motor or complex linkage mechanism.

[0054] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
