Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to an intelligent conveying device and method for producing and packaging crisp pears. Background Art

[0002] With the development of equipment and the improvement of living standards, people's demand for fruits is getting higher and higher. After the fruits are picked, in order to facilitate the transportation of fruits of different qualities to the appropriate location, the fruits will be transported through conveyor belts. The conveyor belts not only provide the effect of aquatic transportation, but also reduce the workload of the staff. During the packaging production process, the crisp pears are also transported to various production stations through conveying devices.

[0003] The reference publication number CN120097004A discloses a conveying device capable of adjusting the relative position of fruits, comprising: an auxiliary plate is provided on the inner side surface of the supporting frame, a baffle is provided on the end surface of the auxiliary plate, a placement groove is provided on the surface of the baffle, a supporting plate is sleeved on the surface of the fixed rod, a limiting groove is provided on the surface of the movable plate, a limiting rod is inserted into the fixed plate, and a lifting groove is provided on the surface of the adjusting plate; the beneficial effects are: first, the limiting nut can be loosened so that the supporting plate can be rotated, and when the supporting plate is rotated to a suitable angle, the limiting nut is tightened, and when the fixed plate is rotated to a suitable angle, the limiting rod is inserted into the limiting groove for fixing, and then the supporting screw can be rotated in conjunction with the limiting bearing to adjust the height of the adjusting plate, and then the surface of the conveyor belt can be divided into multiple areas by cooperating with the adjusting plate and the baffle provided on the side of the conveyor belt, so that fruits of different qualities can be transported conveniently and subsequently packaged.

[0004] During the transportation process, horizontal transportation is often carried out due to site or production needs. When horizontal transportation turns into vertical drop, the fruit is prone to rolling, resulting in loss of posture control, and manual intervention is required to straighten it before labeling and bagging, which increases efficiency loss; free-fall transportation can cause damage to the fruit stem, especially the fruit stem that breaks during impact, which can cause subsequent rot problems; existing sorting equipment cannot detect the mechanical strength of the fruit stem in real time, making it difficult to implement differentiated packaging strategies.

[0020] Step 2: Following the guidance of the guide plate, the crisp pear is transported to the sliding plate, with the head facing downward, and slides down between the two sliding plates until it reaches the placement piece, ensuring that the head is facing downward;

[0021] Step 3: Use the rotating rod to drive multiple rotating frames to rotate. When the rotating frame rotates to the bottom of the placement piece, the pears are dropped by the toggle piece and fall into the receiving mechanism inside the rotating frame. The rotating rod is then used to rotate so that the pears inside the receiving mechanism can be smoothly placed upright on other conveyor belts for the next processing step.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The crisp pears inside the receiving mechanism can be smoothly placed upright on other conveyor belts for the next processing. The crisp pears are vertically transported by the receiving mechanism so that they fall smoothly on another conveyor belt. In order to facilitate subsequent production, the crisp pears are guaranteed to be placed upright. In the subsequent labeling and bagging operations, the lossless vertical transfer of the crisp pears during the transportation process provides the material posture that meets the process requirements for the subsequent packaging process.

[0024] 2. The placement plate is quickly reset under the action of the first spring, and the moving block continues to move at this time. The sliding push plate inside the moving block will contact the slide plate. At this time, the push plate drives the slide plate to slide, and then the slide plate drives the baffle to move through the pull rod, so that the crisp pears blocked by the baffle continue to slide down and slide to the placement plate. When the moving block is reset, the second spring drives the slide plate to reset, so that the baffle is blocked at the top of the sliding plate, so that the crisp pears fall in an orderly manner, ensuring that there is a gap between the falling pears.

[0025] 3. The fixing component is released. At this time, the two clamping frames keep fixing the crisp pears, and then the crisp pears and the two clamping frames descend. After descending to a certain height, by starting the second motor, the support plates on the two clamping frames are close to the third magnetic plate, and then the magnetic blocks and the third magnetic plate are magnetically repelled, so that the crisp pears can smoothly fall upright onto the next conveyor belt, ensuring the upright transportation of the crisp pears, facilitating subsequent processing, and will not cause damage to the crisp pears during the falling process. It is worth noting that the separation position of the two clamping frames is maintained at 90° to the conveyor belt, and when the two clamping frames separate from the crisp pears, they are separated to both sides of the crisp pears, which will not affect the crisp pears.

[0026] 4. The pear stalk is moved by a lever to detect its brittleness, and the state of the pear stalk after movement is observed by a detection camera. The device can detect crisp pears one by one to avoid omissions and avoid the problem of different forces that may occur during manual inspection. By monitoring the brittleness of the pear stalk and grading it, the packaging plan can be optimized to avoid the risk of collective falling due to vibration. At the same time, brittle fruit stalks are easily broken during transportation, resulting in wounds on the fruit stalks that accelerate water loss and rot of the fruit. The device can detect and adjust the environmental humidity in real time to maintain the mechanical strength of the fruit stalk. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0044] like Figures 1 to 13 As shown, an intelligent conveying device and method for producing and packaging crisp pears include the following embodiments:

[0045] Embodiment 1: comprising a conveyor frame 1, wherein a conveyor belt 101 for conveying is provided inside the conveyor frame 1, and further comprising:

[0046] The guide mechanism includes two guide plates 2 arranged opposite to each other. Electric push rods 201 are fixedly connected to both sides of the top of the conveyor frame 1. The telescopic ends of the electric push rods 201 are fixedly connected to the guide plates 2. A sliding plate 3 is provided at one end of each guide plate 2. A placement piece is provided at one end of each sliding plate 3, and a toggle assembly is provided between the placement piece and the sliding plate 3.

[0047] The rotating frame 4 is fixedly connected to one end of the conveying frame 1 and is arranged below the sliding plate 3. The rotating frame 4 is rotatably connected to a rotating rod 401 inside, and a plurality of rotating frames 6 are fixedly connected to the outside of the rotating rod 401. The rotating frames 6 are each provided with a receiving mechanism inside. By rotating the rotating rod 401, the crisp pears inside the receiving mechanism are placed upright.

[0048] In specific implementation, during the production and packaging process of crisp pears, they are often transported on multiple conveyor belts, and there are differences in height between the conveyor belts. If sliding conveying is adopted, the inclination angle is too large and the conveying production line is long. Therefore, it is often necessary to transport the crisp pears vertically. The surface of the crisp pears is relatively fragile. If they fall vertically, the surface of the pears will inevitably be damaged. Therefore, in this solution, the crisp pears are transported on the conveyor belt 101 and guided by the guide plate 2 so that the crisp pears are transported in sequence. With the guidance of the guide plate 2, the crisp pears are transported to the sliding plate 3 with their heads facing downwards, and slide down between the two sliding plates 3 until they slide down to the placement piece to ensure that their heads are facing downwards. Then, the rotating rod 401 drives multiple rotating frames 6 to rotate. When the rotating frame 6 rotates to the bottom of the placement piece, the pears are dropped by the toggle piece and fall into the receiving mechanism inside the rotating frame 6. The rotating rod 401 is rotated so that the pears inside the receiving mechanism can be smoothly placed upright on other conveyor belts for the next processing. The pears are vertically transported by the receiving mechanism so that they fall smoothly on another conveyor belt. In order to facilitate subsequent production, it is ensured that the pears can be placed upright. In the subsequent labeling and bagging operations, the pears are transported vertically without loss during transportation, which provides a material posture that meets the process requirements for the subsequent packaging process.

[0049] Embodiment 2: A driving motor 403 is fixedly connected to the outside of the rotating frame 4, the output shaft of the driving motor 403 is fixedly connected to the rotating rod 401, and incomplete gear rings 402 are fixedly connected on both sides of the inside of the rotating frame 4, and a first magnetic plate 404 is fixedly connected on both sides of the inside of the rotating frame 4, and the first magnetic plate 404 is arranged directly below the placement piece.

[0050] The placement piece includes a fixed frame 302, which is fixedly connected to one end of the sliding plate 3, and a placement plate 301 is slidably connected inside the fixed frame 302, and the placement plate 301 is kept level with the ground. A first spring 304 is provided inside the fixed frame 302, and the two ends of the first spring 304 are respectively fixedly connected to the fixed frame 302 and the placement plate 301.

[0051] During specific implementation, when the crisp pears are transported by the conveyor belt 101 and guided by the guide plate 2, the crisp pears are placed horizontally. The front part of the guide plate 2 is curved, and a protective film is provided on the surface for protection to avoid damage to the crisp pears during contact. When the crisp pears are transported to the position of the sliding plate 3, the bottom of the crisp pears slides between the two sliding plates 3, and the top is placed downward and slides to the placement plate 301. The placement plate 301 is set horizontally. At this time, the crisp pears are in a head-down state, which is convenient for the next operation.

[0052] In this embodiment, the toggle assembly includes a blocking member and a pushing member, the blocking member includes a baffle 5, the baffle 5 is arranged on the top of the sliding plate 3, a slide plate 502 is arranged on the outside of the sliding plate 3, a pull rod 501 is fixedly connected between the slide plate 502 and the baffle 5, a telescopic rod 503 and a second spring 504 are fixedly connected between the slide plate 502 and the sliding plate 3, and the second spring 504 is sleeved on the outside of the telescopic rod 503.

[0053] The pushing member includes a mounting plate 505, which is fixedly connected to the top of the sliding plate 3, and the slide plate 502 is arranged on the top of the mounting plate 505. The driving screw 506 is rotatably connected inside the mounting plate 505, and the outer side of the driving screw 506 is connected to the moving block 507 through a ball nut pair. The pushing plate 508 is slidably connected inside the moving block 507, and the bottom of the pushing plate 508 is fixedly connected to the limiting shaft 509. The top of the mounting plate 505 is provided with a first slide groove 5051, a third slide groove 5053 and a second slide groove 5052. The first slide groove 5051 is connected to the second slide groove 5052 through the third slide groove 5053, and one end of the second slide groove 5052 is connected to the first slide groove 5051. The limiting shaft 509 extends to the inside of the third slide groove 5053. The top of the placement plate 301 is fixedly connected to a connecting plate 510, and the connecting plate 510 extends to the top of the mounting plate 505.

[0054] During specific implementation, when one crisp pear is between the two placement plates 301 and the other crisp pear is on the sliding plate 3, the crisp pears are blocked by the baffle 5, so that the crisp pears are unloaded in order. When the crisp pears on the placement plate 301 need to fall, a second motor is installed on the outside of the mounting plate 505, and the output shaft of the second motor is fixedly connected to the driving screw 506. At this time, the driving screw 506 rotates, and the driving screw 506 drives the moving block 507 to move, and drives the pushing plate 508 slidingly connected inside the moving block 507 to move together, and the limiting shaft 509 at the bottom of the pushing plate 508 is inside the second slide groove 5052, and the moving block 507 drives the pushing plate 508 to contact the connecting plate 510 first. At this time, the pushing plate 508 pushes the connecting plate 510, so that the connecting plate 510 pulls the fixed placement plate 301 to move, so that the two placement plates 301 are relatively far apart. The pear falls with its head facing downward and falls into the receiving mechanism inside the rotating frame 6, and the limit shaft 509 moves along the second slide groove 5052 and then into the first slide groove 5051. At this time, the push plate 508 separates from the connecting plate 510, and the placement plate 301 is quickly reset under the action of the first spring 304. At this time, the moving block 507 continues to move, and the sliding push plate 508 inside the moving block 507 will contact the slide plate 502. At this time, the push plate 508 drives the slide plate 502 to slide, and then the slide plate 502 drives the baffle 5 to move through the pull rod 501, so that the pear blocked by the baffle 5 continues to slide down and slides to the placement plate 301. When the moving block 507 is reset, the second spring 504 drives the slide plate 502 to reset, so that the baffle 5 is blocked at the top of the sliding plate 3, so that the pears fall in an orderly manner, ensuring that there is a gap between the falling pears.

[0055] Example three: The receiving mechanism includes a buffer component and a fixed component. The buffer component includes a mounting ring 601. The mounting ring 601 is fixedly connected to two side plates 602. Two sliding rods 604 are fixedly connected inside the rotating frame 6. The two sliding rods 604 respectively pass through the two side plates 602 and are slidably connected to the side plates 602. A second magnetic plate 603 is fixedly connected to the top of the side plate 602. The second magnetic plate 603 is magnetically attracted to the first magnetic plate 404. When the second magnetic plate 603 is below the first magnetic plate 404, the second magnetic plate 603 rises due to magnetic attraction.

[0056] The buffer assembly also includes a rotating ring gear 701, which is rotatably connected to the bottom of the mounting ring 601, and the outer side of the rotating ring gear 701 is meshed with a first gear 702, the top of one of the side plates 602 is fixedly connected to a first motor, the output shaft of the first motor is fixedly connected to the first gear 702, and the bottom of the rotating ring gear 701 is fixedly connected to two relatively arranged mounting frames 703, the interior of the mounting frame 703 is slidably connected to a support plate 704, the outer side of the support plate 704 is fixedly connected to a magnetic block 706, the bottom of the support plate 704 is fixedly connected to a clamping frame 705, the inner side of the clamping frame 705 is fixedly connected to an air cushion, a spring 707 is provided inside the mounting frame 703, and the two ends of the spring 707 are respectively fixedly connected to the support plate 704 and the mounting frame 703, and the bottom of the two side plates 602 are fixedly connected to a third magnetic plate 708, and the third magnetic plate 708 is magnetically attracted to the magnetic block 706.

[0057] During specific implementation, when the driving motor 403 drives the rotating rod 401 to rotate, the rotating rod 401 drives multiple fixedly connected rotating frames 6 to rotate, and when one of the rotating frames 6 rotates to the bottom of the placement plate 301, the second magnetic plate 603 on the two side plates 602 inside the rotating frame 6 is magnetically attracted to the first magnetic plate 404, driving the mounting ring 601 to rise close to the bottom of the crisp pear, ensuring that the crisp pear can pass through the mounting ring 601 and fall between the two clamping frames 705. At the same time, the first gear 702 is driven to rotate by the output shaft of the second motor, and the first gear 702 drives the meshing connection The rotating gear ring 701 drives the two clamping frames 705 to approach the third magnetic plate 708. At this time, the spring 707 on the installation frame 703 pulls the support plate 704, so that the two support plates 704 move away from each other, ensuring that the crisp pear can fall between the two clamping frames 705. When the crisp pear falls smoothly into the two clamping frames 705, an air cushion is provided on the inside of the clamping frame 705 to ensure that the crisp pear will not be damaged between the two clamping frames 705. The second motor is started again to rotate the installation frame 703 to the two third magnetic plates 708. The magnetic block 706 on the support plate 704 is separated from the third magnetic plate 708. The pears are fixed to the two clamping frames 705, and the second magnetic plate 603 is separated from the first magnetic plate 404 as the rotating frame 6 rotates. At this time, the pears inside the two clamping frames 705 are lowered by gravity, so that the ends of the pears between the two clamping frames 705 pass through the fixing assembly and the pears are further fixed by the fixing assembly. When the rotating frame 6 rotates 180 degrees, the bottom of the pear faces downward, and the fixing assembly is released. At this time, the two clamping frames 705 keep fixing the pears, and the pears and the two clamping frames 705 fall. When it descends to a certain height, by starting the second motor, the support plates 704 on the two clamping frames 705 are close to the third magnetic plate 708, and then the magnetic block 706 and the third magnetic plate 708 are magnetically repelled, so that the crisp pears can smoothly fall upright onto the next conveyor belt, ensuring the upright transportation of the crisp pears, facilitating subsequent processing, and will not cause damage to the crisp pears during the falling process. It is worth noting that the separation position of the two clamping frames 705 is maintained at 90° to the conveyor belt, and then when the two clamping frames 705 separate from the crisp pears, they are separated to both sides of the crisp pears, which will not affect the crisp pears.

[0058] Embodiment 4: The fixed assembly includes a fixed frame 8, which is fixedly connected to the inside of the rotating frame 6. An inflatable airbag 801 is fixedly connected to the inside of the fixed frame 8, and an air pump is provided inside the rotating frame 6 to control the expansion and contraction of the inflatable airbag 801.

[0059] A detection camera 905 is fixedly connected to the bottom end of the rotating frame 6, and transmission rods 901 are rotatably connected on both sides of the rotating frame 6. A plurality of toggle rods 902 are fixedly connected between the two transmission rods 901, and a second gear 903 is fixedly connected to the outside of the transmission rod 901. The second gear 903 is meshed with the incomplete gear ring 402 and is used to toggle the stalk of the crisp pear to detect its crispness.

[0060] In a specific implementation, when the head of the crisp pear passes through the fixed frame 8 in the fixed assembly, it is connected to the inflatable airbag 801 through the output end of the air pump, and by starting the air pump, the inflatable airbag 801 is inflated, and then the inflatable airbag 801 fixes the head of the crisp pear, and when the rotating frame 6 rotates, the second gear 903 on the outside of the rotating frame 6 is engaged with the teeth of the incomplete gear ring 402, and then the second gear 903 drives the transmission rod 901 to rotate. When the transmission rod 901 rotates, it drives multiple toggle rods 902 to rotate, and the toggle rods 902 contact the pear handle of the head of the crisp pear, through The lever 902 moves the pear stem to detect the crispness of the pear stem, and the state of the pear stem after the movement is observed by the detection camera 905. The crisp pears can be detected one by one through the device to avoid omissions, and at the same time avoid the problem of different forces that are prone to occur during manual inspection. By monitoring the crispness of the pear stem and grading it, the packaging plan can be optimized in a targeted manner to avoid the risk of collective falling due to vibration. At the same time, the brittle fruit stem with a water content of less than 68% is easy to break during transportation, resulting in wounds on the fruit stem that accelerate water loss and rot of the fruit. The environmental humidity can be adjusted to 85% to 95% in real time to maintain the mechanical strength of the fruit stem.

[0061] A method for intelligent conveying for production and packaging of crisp pears, comprising the following steps:

[0062] Step 1: When the crisp pears are transported on the conveyor belt 101, the crisp pears are guided by the guide plate 2 so that the crisp pears are transported in sequence;

[0063] Step 2: Following the guidance of the guide plate 2, the crisp pear is transported to the sliding plate 3, with the head of the crisp pear facing downward, and slides down between the two sliding plates 3 until it reaches the placement piece, ensuring that the head is facing downward;

[0064] Step three: Use the rotating rod 401 to drive multiple rotating frames 6 to rotate. When the rotating frame 6 rotates to the bottom of the placement piece, the pears are dropped by the toggle piece and fall into the receiving mechanism inside the rotating frame 6.
