Description

Technical Field

[0001] This invention relates to the field of fruit conveying technology, and more specifically to an intelligent conveying device for fruit raw materials. Background Technology

[0002] Canned fruits, such as apples, pears, and peaches, undergo a process of washing, sorting, cutting, and pitting during production. They are then soaked in sugary water, sterilized at high temperatures, and finally canned. To maximize the use of the fruit pulp during transport, the fruit is usually cut in half first, and the pit is removed. Then, the halved pieces of fruit are cut again. During this process, the fruit is usually aligned with the cutting blade, with the stem end and the bottom facing the blade. This allows the blade to cut the fruit along the longitudinal axis of symmetry of the pit, facilitating subsequent pitting.

[0003] Before the fruit needs to be cut in half, it goes through multiple transport steps. Positioning the fruit is relatively difficult, and high-precision positioning instruments are usually expensive. Therefore, manual cutting in half is the conventional choice. The fruit is also transported during the sorting of bad fruit, and manual or machine sorting is also used. Therefore, is it possible to combine the two steps of transport and fruit positioning to help improve efficiency? Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an intelligent conveying device for fruit raw materials, which can effectively solve the problem of how to combine the two steps of conveying and fruit positioning in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides an intelligent conveying device for fruit raw materials, including a conveyor belt support, a drive roller, and a chain. A motor and a reducer are mounted on the conveyor belt support to drive the drive roller to rotate, and the drive roller drives the chain to move. The device also includes:

[0007] A receiving plate, connected between two symmetrically distributed chains, is used to receive fruit. It includes a plate body that is fixedly connected between the two chains and rotatably connected to the plate body, located in the middle of the plate body. A pair of semi-circular grooves are symmetrically opened on the plate body.

[0008] The positioning component, located above the conveyor belt support, contacts and rotates the fruit to assist in positioning the fruit. It includes two support frames fixedly installed on the conveyor belt support. A horizontal plate is fixedly connected to the top of the support frame, and a rubber rotating belt is vertically rotatably connected to the horizontal plate. The rubber rotating belt is driven by a motor and contacts the fruit to adjust the fruit's orientation.

[0009] Furthermore, the receiving plate also includes a rigid rubber ring fixedly installed at the bottom of the semi-circular groove. A flexible rubber pad is fixedly connected to the top of the rigid rubber ring. The flexible rubber pad supports the fruit in the semi-circular groove and provides elastic compression to the surrounding area when the fruit is embedded in the semi-circular groove. Multiple neodymium magnets are embedded and fixedly connected to the two side walls of the plate. When the plate is in a horizontal state, the neodymium magnets between the multiple plates attract each other to form a flat plane.

[0010] Furthermore, the positioning assembly also includes a mounting bracket fixedly installed on the top of the horizontal plate. The horizontal plate has multiple slots for the fruit to pass through, and these slots correspond to the positions of the semi-circular slots and neodymium magnets. Multiple cylinders are embedded and fixedly connected to the mounting bracket. The output end of each cylinder faces downward and is fixedly connected to a moving column. A rubber protrusion is fixedly connected to the bottom end of the moving column. Multiple flexible capacitive sensors are embedded and fixedly connected to the circumference of the rubber protrusion. The multiple flexible capacitive sensors form a detection array to detect whether the two longitudinal ends of the fruit are distributed vertically.

[0011] Furthermore, a fixed frame is fixedly fitted onto the movable column, and an electromagnet is fixedly connected to the side plate of the fixed frame. The electromagnet is magnetically attracted to a vertical plate, and an inclined elastic plate is fixedly connected to the bottom end of the vertical plate. Multiple springs are fixedly connected between the inclined elastic plate and the vertical plate. Both the vertical plate and the inclined elastic plate can slide through the horizontal plate, and elastic rubber pads corresponding to the vertical plate and the inclined elastic plate are fixedly connected to the groove sidewall of the horizontal plate. When the vertical plate and the inclined elastic plate descend, the elastic rubber pads are inserted, causing the elastic rubber pads to expand in the direction of the rubber rotating belt, increasing the contact between the fruit and the rubber rotating belt, and using the rotating rubber rotating belt to drive the fruit to rotate up and down.

[0012] Furthermore, the sidewall of the horizontal plate is fixedly connected to a groove located below the horizontal plate, which is used to arrange the fruit.

[0013] Furthermore, an upper positioning and pressing assembly is installed on the top of the conveyor belt support for detecting the position of the fruit. This assembly includes a mounting base fixedly installed on the top of the conveyor belt support. Multiple bases are fixedly connected to the bottom of the horizontal plate of the mounting base. Two cylinders are symmetrically rotatably connected to the bottom of the bases. The output ends of the cylinders face downwards and are rotatably connected to rubber contact blocks. Two rubber contact blocks are symmetrically distributed and fixedly connected to one side close to each other. A rubber tip is fixedly connected to one side. The rubber tip contacts the inner side of the two longitudinal ends of the fruit. A flexible capacitive sensor is embedded and fixedly installed on the outer side of the rubber tip for detecting the position of the longitudinal ends of the fruit.

[0014] Furthermore, a telescopic rod is fixedly connected to the bottom of the base, and a bidirectional electromagnet is fixedly connected to the bottom end of the telescopic rod. The bidirectional electromagnet generates a magnetic attraction force, and the two are rotatably connected together. Both ends of the base have protrusions and slide between the two, restricting the position between the two and using the protrusions to prevent the two from separating from left to right.

[0015] Furthermore, a fixed plate is fixedly connected inside the conveyor belt bracket. A stem-pulling positioning component corresponding to the upper positioning and pressing component is fixedly connected to the top of the fixed plate. The stem-pulling positioning component is used to detect the position of the fruit from below and remove the fruit stem. It includes a base plate fixedly installed on the top of the fixed plate. An electric push rod is fixedly connected to the top of the base plate. The output end of the electric push rod faces upward and is fixedly connected to a mounting shell. A stepper motor is fixedly connected inside the mounting shell. A bidirectional double-outlet cylinder is fixedly connected to the top of the shaft of the stepper motor. Symmetrically distributed moving blocks are fixedly connected to the two moving ends of the bidirectional double-outlet cylinder. A rigid stem-pulling block is fixedly connected to the side of the two moving blocks that are close to each other. The top of the moving block has an arc-shaped contact surface, and a flexible capacitive sensor is embedded and fixedly connected in the arc-shaped contact surface.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0017] 1. By using a receiving plate, a stopping position can be provided for the fruit. In conjunction with the positioning component, the position of the fruit can be adjusted. Using a flexible capacitive sensor, the position of the fruit can be roughly determined. When the concave part of the fruit end is facing upward, the rotation drive of the fruit is stopped. In this way, the fruit can be positioned during the fruit conveying process.

[0018] 2. The fruit position can be determined by the stem-pulling positioning component and the upper positioning pressing component, and the fruit can be pressed into the receiving plate to fix the fruit position and prepare for the next step of cutting, which facilitates the subsequent cutting.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] The present invention will be further described below with reference to embodiments.

[0038] Reference Figures 1 to 15 Example: An intelligent conveying device for fruit raw materials includes a conveyor belt support 1, a drive roller 2, and a chain 3. A motor and a reducer are mounted on the conveyor belt support 1 to drive the drive roller 2 to rotate, and the drive roller 2 drives the chain 3 to move. The device also includes:

[0039] The receiving plate 4 is connected between two symmetrically distributed chains 3 and is used to receive fruit. It includes a rotating shaft 406 fixedly connected between the two chains 3 and a plate body 401 rotatably connected to the rotating shaft 406. The rotating shaft 406 is located in the middle of the plate body 401, and a pair of semi-circular grooves 405 are symmetrically opened on the plate body 401.

[0040] The positioning component 5 is located above the conveyor belt support 1. It contacts and rotates the fruit to assist in positioning the fruit. It includes two support frames 501 fixedly installed on the conveyor belt support 1. A horizontal plate 502 is fixedly connected to the top of the support frame 501. A rubber rotating belt 503 is vertically rotatably connected to the horizontal plate 502. The rubber rotating belt 503 is driven by a motor and contacts the fruit to adjust the fruit's orientation.

[0041] Before making canned fruit, the raw fruit needs to be washed. After washing, the fruit is sorted to remove bad fruit. After being cut in half, the peel is removed and the pit is removed by means of acid leaching. Then, it is cut into several small pieces, canned, and filled with sugar water. After being sterilized at high temperature, the basic production of canned fruit is completed. The next step is the packaging stage.

[0042] When halving the fruit, in order to facilitate the removal of the pit later, it is necessary to cut along the longitudinal growth lines of the pit, that is, along the "bottom" and stem of the fruit. This is especially true in the production of canned peaches. After cutting yellow peaches in half along the "bottom", the pit can be easily removed. After peeling and acid treatment, the fruit can proceed to the next step.

[0043] The motor and reducer connected to the conveyor belt support 1 drive the drive roller 2 to rotate, which in turn drives two sets of chains 3. A rotating shaft 406 is installed between the two sets of chains 3. Rotatable plates 401 are mounted on the rotating shaft 406. A torsion spring is connected between the plates 401 and the rotating shaft 406. In the straight section of the chain 3, the plates 401 are attracted together by neodymium magnets 404. Utilizing the elastic support of the torsion springs and the attraction of the neodymium magnets 404, multiple plates 401 together form a straight section. The semi-circular grooves 405 on adjacent plates 401 together form a circle. Fruit raw materials can fall into the circular space formed by the semi-circular grooves 405 between two plates 401, achieving a certain limiting effect and moving together with the plates 401. Figure 2 As shown, the arrow indicates the direction of fruit movement on the receiving plate 4. After the fruit moves to below the adjusting component 5, the rubber rotating belt 503 driven by the motor rotates up and down. The single rubber rotating belt 503 exerts a lateral force on the fruit in the two slots of the horizontal plate 502. At this time, the fruit moves longitudinally along the receiving plate 4. The vertical rotation of the rubber rotating belt 503 drives the fruit vertically by contacting it. After the longitudinal movement of the fruit comes into contact with the rubber rotating belt 503, it can generate a certain lateral force, which will cause the fruit to move longitudinally and laterally, helping to adjust the orientation of the fruit. In this step, the position of the fruit can be adjusted, which, together with subsequent detection and positioning, can help determine the position of the fruit.

[0044] Specifically, the receiving plate 4 also includes a rigid rubber ring 403 fixedly installed at the bottom of the semi-circular groove 405. A flexible rubber pad 402 is fixedly connected to the top of the rigid rubber ring 403. The flexible rubber pad 402 supports the fruit in the semi-circular groove 405 and generates elastic compression around the fruit when the fruit is embedded in the semi-circular groove 405. Multiple neodymium magnets 404 are embedded and fixedly connected to the two side walls of the plate body 401. When the plate body 401 is in a horizontal state, the neodymium magnets 404 between the multiple plate bodies 401 attract each other to form a flat plane.

[0045] The flexible rubber pads 402 between two adjacent plates 401 are filled together in the semi-circular groove 405, which can provide a certain degree of support for the fruit. The rigid rubber ring 403 provides additional support, limiting the deformation range of the flexible rubber pads 402 and preventing the fruit from getting stuck between the multiple flexible rubber pads 402. Subsequently, by applying a downward force to the fruit, the flexible rubber pads 402 are forced to deform downward. The deformation of the flexible rubber pads 402 and the support of the rigid rubber ring 403 can be used to clamp or restrict the fruit in the semi-circular groove 405 and fix the position of the fruit. This can not only stably support the fruit and avoid damage to the fruit flesh caused by shaking and collision during transportation, but also adapt to fruits of different sizes, improving the versatility of the equipment.

[0046] When the plate 401 moves to the drive roller 2, the neodymium magnets 404 between the plates 401 separate, and due to the change in angle, the plates 401 also separate, so that the fruit can be taken out from between the plates 401 for halving.

[0047] Specifically, the positioning component 5 also includes a mounting bracket 504 fixedly installed on the top of the horizontal plate 502. The horizontal plate 502 has multiple slots for fruit to pass through, and these slots correspond to the positions of the semi-circular slot 405 and the neodymium magnet 404. A triangular guide bracket 514 is fixedly connected to the side wall of the horizontal plate 502, positioned between the slots below the horizontal plate 502, for positioning the fruit. Multiple cylinders 506 are embedded and fixedly connected to the mounting bracket 504. The output ends of the cylinders 506 face downwards and are fixedly connected to a moving column 505. A rubber protrusion 507 is fixedly connected to the bottom end of the moving column 505. Multiple flexible capacitive sensors 508 are embedded and fixedly connected to the circumference of the rubber protrusion 507. The multiple flexible capacitive sensors 508 form a detection array to detect whether the two longitudinal ends of the fruit are vertically distributed. A fixed frame 509 is fixedly mounted on the upper part of the 05. An electromagnet 512 is fixedly connected to the side plate of the fixed frame 509. The electromagnet 512 is magnetically attracted to a vertical plate 510. An inclined elastic plate 511 is fixedly connected to the bottom end of the vertical plate 510. Multiple springs are fixedly connected between the inclined elastic plate 511 and the vertical plate 510. Both the vertical plate 510 and the inclined elastic plate 511 can slide through the horizontal plate 502. An elastic rubber pad 513 corresponding to the vertical plate 510 and the inclined elastic plate 511 is fixedly connected to the side wall of the groove of the horizontal plate 502. When the vertical plate 510 and the inclined elastic plate 511 descend, the elastic rubber pad 513 is inserted, causing the elastic rubber pad 513 to expand in the direction of the rubber rotating belt 503, increasing the contact between the fruit and the rubber rotating belt 503. The rotating rubber rotating belt 503 drives the fruit to rotate up and down.

[0048] Multiple cylinders 506 are arranged along the direction of fruit movement and directly above the slot in the horizontal plate 502. Controlled by a program, these cylinders 506 sequentially perform repetitive up-and-down movements, creating a wave-like motion. The moving column 505 below each cylinder does not move synchronously. When the flexible capacitive sensor 508 on the rubber protrusion 507 contacts the fruit's stem or "bottom" portion, it detects the fruit's position through capacitance changes. When the rubber protrusion 507 can penetrate into the two recessed ends of the fruit, the flexible capacitive sensor... Sensor 508 can only roughly determine that one end of the fruit is facing upwards by contacting it. Simultaneously, as the moving column 505 descends driven by cylinder 506, the fixing frame 509 also descends along with the iron vertical plate 510 and the inclined elastic plate 511. The vertical plate 510 and the inclined elastic plate 511 pass through the top of the horizontal plate 502 and insert between the elastic rubber pad 513 and the groove of the horizontal plate 502, causing the elastic rubber pad 513 to expand towards the rubber rotating belt 503, forcing the fruit towards the rubber rotating belt 503. 3. Movement increases the contact between the fruit and the elastic rubber pads 513, allowing the fruit to move stably in multiple directions. Multiple elastic rubber pads 513 work together to maximize the fruit's rotation. After the flexible capacitive sensor 508 below one of the cylinders 506 detects the fruit, the electromagnet 512 behind that cylinder 506 is de-energized. This means that subsequent cylinders 506 continue their up-and-down reciprocating motion, but the vertical plate 510 loses the attraction of the electromagnet 512 and cannot continue to move downwards with the moving column 505. The vertical plate 510 and the inclined elastic plate 511 can pass through the slots on the fixing frame 509. The subsequent vertical plate 510 and the inclined elastic plate 511 cannot extend between the elastic rubber pads 513. That is, one side of the fruit cannot be squeezed by the elastic rubber pads 513, and thus the fruit loses contact with the rubber rotating belt 503, preventing the fruit's position from changing. In contrast, the subsequent cylinder 506 moves up and down repeatedly, which to some extent helps to determine the fruit's position through the downward movement, and also continuously detects whether the fruit's position has shifted.

[0049] The triangular shape of the triangular guide 514 is between the two slots, so that the two sides of the slots form a funnel shape, which can guide the fruit into the slot of the horizontal plate 502, that is, near the position of the semi-circular slot 405, to help adjust the position of the fruit.

[0050] Specifically, an upper positioning and pressing assembly 6 is installed on the top of the conveyor belt support 1 for detecting the position of the fruit. This assembly includes a mounting base 601 fixedly installed on the top of the conveyor belt support 1. Multiple bases 602 are fixedly connected to the bottom of the horizontal plate of the mounting base 601. Two cylinders 603 are symmetrically rotatably connected to the bottom of the bases 602. The output ends of the cylinders 603 face downwards and are rotatably connected to rubber contact blocks 604. The two rubber contact blocks 604 are symmetrically distributed and a pressing plate 610 is fixedly connected to one side of each other. A rubber tip 605 is fixedly connected to one side of the pressing plate 610. The rubber tip 605 contacts the inner side of the two longitudinal ends of the fruit. A flexible capacitive sensor 606 is embedded and fixedly installed on the outer side of the rubber tip 605 for detecting the position of the longitudinal ends of the fruit.

[0051] The fruit then moves with the plate 401 and moves to below the rubber tip 605. Driven by the cylinder 603, the rubber tip 605 moves downward. Flexible capacitive sensors 606 are installed on the arc-shaped surfaces of the two rubber tips 605. When the two flexible capacitive sensors 606 move downward, they will contact the concave end of the fruit. Only then can one of the two flexible capacitive sensors 606 detect the fruit through the change in capacitance after contact. After passing the adjustment component 5, the fruit is roughly in a position with the concave end facing upward, thus detecting the fruit's position. At the same time, the simultaneous descent of the two rubber tips 605 can generate downward pressure on the fruit from top to bottom.

[0052] Specifically, a telescopic rod 607 is fixedly connected to the bottom of the base 602, and a bidirectional electromagnet 608 is fixedly connected to the bottom end of the telescopic rod 607. The bidirectional electromagnet 608 generates a magnetic attraction force on the pressing plate 610. A rotating connector 609 is rotatably connected between the two pressing plates 610. The rotating connector 609 has protrusions at both ends and slides between the two pressing plates 610, limiting the position between the two pressing plates 610. The protrusions of the rotating connector 609 prevent the two pressing plates 610 from separating left and right.

[0053] After the flexible capacitive sensor 606 detects the fruit (i.e., the fruit's concave end is facing upwards), the cylinder 603 continues to press downwards, simultaneously de-energizing the bidirectional electromagnet 608 that simultaneously attracts the two pressing plates 610. Under the continuous pressure of the cylinder 603, the two pressing plates 610 rotate outwards, causing the rubber contact blocks 604 and rubber tips 605 on both sides to open to the sides and cover the fruit. The two rubber tips 605 then continuously press the fruit downwards, forcing the flexible rubber pads 402 between the two plates 401 to deform downwards. With the elastic support of the flexible rubber pads 402 and the restriction of the hard rubber rings 403, the fruit can be stuck in the semi-circular grooves 405. In this way, the position of the fruit can be restricted, preventing the fruit from changing position due to inertia when moving with the receiving plate 4.

[0054] It is important to note that when the bidirectional electromagnet 608 generates magnetic attraction and the two pressing plates 610 come together, the two cylinders 603 should be slightly open outwards. This way, when the bidirectional electromagnet 608 is de-energized, the cylinders 603 can exert an outward pushing force on the rubber tip 605 at this angle, preventing the pushing force of the cylinders 603 on the rubber tip 605 from being vertically downwards after the bidirectional electromagnet 608 is de-energized. When the cylinders 603 retract, they will also bring the rubber tip 605 back to its original position. Then the bidirectional electromagnet 608 will activate, attracting the two pressing plates 610 together to complete the reset. Alternatively, a magnet can be embedded in the position where the two pressing plates 610 attract the bidirectional electromagnet 608. When the rubber tip 605 needs to open, the magnetism of the bidirectional electromagnet 608 can be reversed, using repulsive force to rotate the two pressing plates 610 outwards.

[0055] Specifically, a fixed plate 8 is fixedly connected inside the conveyor belt bracket 1. A stem-pulling positioning component 7 corresponding to the upper positioning and pressing component 6 is fixedly connected to the top of the fixed plate 8. The stem-pulling positioning component 7 is used to detect the position of the fruit from below and remove the fruit stem. It includes a base plate 701 fixedly installed on the top of the fixed plate 8. An electric push rod 702 is fixedly connected to the top of the base plate 701. The output end of the electric push rod 702 faces upward and is fixedly connected to a mounting shell 703. A stepper motor 704 is fixedly connected inside the mounting shell 703. A bidirectional double-outlet cylinder 705 is fixedly connected to the top of the shaft of the stepper motor 704. Symmetrically distributed moving blocks 706 are fixedly connected to the two moving ends of the bidirectional double-outlet cylinder 705. A rigid stem-pulling block 707 is fixedly connected to the side of the two moving blocks 706 that is close to each other. The top of the moving block 706 has an arc-shaped contact surface, and a flexible capacitive sensor 708 is embedded and fixedly connected in the arc-shaped contact surface.

[0056] The base plate 701 can be located between the conveyor belt supports 1, i.e., below the fruit, or it can be distributed above the conveyor belt supports 1, i.e. above the fruit, or the base plate 701 can be set both above and below the fruit. If the electric push rod 702 is located below the upper positioning and pressing component 6, the electric push rod 702 needs to move together with the rubber rotating belt 503 to simultaneously position both ends of the fruit. This method is for fruits such as apples and pears. If it is for peaches, the base plate 701 should be above the fruit, and the electric push rod 702 should drive the bidirectional double-outlet cylinder 705 from top to bottom to move downwards so as to make it easy to contact the end recess of the fruit and use two hard stem-pulling blocks 707 to clamp the fruit stem.

[0057] When the electric push rod 702 drives the stepper motor 704 and the flexible capacitive sensor 708 to move towards the fruit, the two moving ends of the bidirectional double-outlet cylinder 705 are in a separated state. The flexible capacitive sensor 708 at the end of the moving block 706 contacts the end recess, and then the two moving ends of the bidirectional double-outlet cylinder 705 immediately move closer. The rigid stem-pulling block 707 quickly clamps the fruit stem, and the stepper motor 704 rotates rapidly several times to break the fruit stem. Then, the output end of the electric push rod 702 retracts, thus removing the fruit stem. Then, when the moving block 706 resets under the drive of the bidirectional double-outlet cylinder 705, the fruit stem will naturally detach. It should be noted that the moving block... When 706 is below the fruit, when the electric push rod 702 retracts to remove the stem, the fruit is restricted by the flexible rubber pad 402 and the hard rubber ring 403, preventing the fruit from moving downwards and allowing the stem to be removed smoothly. During the stem removal process, cylinder 603 should have already moved down and returned to its original position. In this way, when the fruit is driven by the receiving plate 4, it will not be restricted by both the upper and lower parts simultaneously when the stem is removed, thus avoiding damage to the fruit. When the moving block 706 is above the fruit, it must be behind the upper positioning and pressing component 6. After the fruit is stuck in the flexible rubber pad 402 and the hard rubber ring 403, the stem removal action is performed to prevent the fruit from shifting position during the stem removal process.
