[0002] Fruit cans, such as apple, pear and peach cans, need to be washed, selected, cut and cored, then soaked in sugar water, sterilized at high temperature, and finally canned. In the conveying of raw materials, in order to maximize the use of fruit pulp, the fruit raw materials are usually cut in half first, and then the fruit pulp is cut again. In this process, the fruit needs to be aligned with the cutting blade, with the head and "butt" of the fruit stem facing the blade, so that the blade can cut the fruit in half along the longitudinal axis of the core, facilitating subsequent coring.

DETAILED DESCRIPTION

[0018] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0019] The present application will be further described below with reference to the embodiments.

[0020] With reference to Figures 1 to 15 Embodiment: An intelligent fruit raw material conveying device, comprising a conveying belt support 1, a driving roller 2 and a chain 3, a motor and a speed reducer are installed on the conveying belt support 1 to drive the driving roller 2 to rotate, and the driving roller 2 drives the chain 3 to move, further comprising: a receiving plate 4 connected between the two symmetrically distributed chains 3 for receiving fruits, comprising 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 being located in the middle of the plate body 401, and a pair of semicircular grooves 405 being symmetrically formed in the plate body 401; a positioning assembly 5 distributed above the conveying belt support 1 to contact and rotate the fruits and assist in positioning the position of the fruits, comprising two support frames 501 fixedly installed on the conveying belt support 1, a horizontal plate 502 fixedly connected to the top of the support frame 501, and a rubber rotating belt 503 vertically rotatably connected to the horizontal plate 502, the rubber rotating belt 503 being driven by a motor and contacting the fruits to adjust the orientation of the fruits.

[0021] Before the fruit raw material is made into cans, it needs to be washed, the washed fruits are screened to remove bad fruits, after being cut in half, the fruit skin is removed by means of acid spraying, and the fruit pits are removed, then the fruits are cut into small pieces, canned, injected with sugar water, and then sterilized at high temperature to complete the basic production of the cans, and the subsequent step is the packaging step.

[0022] When cutting in half, in order to facilitate the removal of the fruit pits subsequently, the fruits need to be cut along the longitudinal growth lines of the fruit pits, i.e. the fruits are cut in half along the "buttocks" and the positions of the fruit stems, especially in the production of peach cans, after the yellow peaches are cut in half along the "buttocks", the pits can be removed smoothly, and then the fruits are peeled by spraying acid and enter the next step.

[0023] The motor and reducer connected on the conveying belt support 1 drive the driving roller 2 to rotate and drive the two groups of chains 3 to rotate. The rotating shaft 406 is installed between the two groups of chains 3. The rotatable plate body 401 is installed on the rotating shaft 406. The plate body 401 and the rotating shaft 406 have a torsion spring. The plate bodies 401 are attracted together by the neodymium magnets 404 at the flat parts of the chains 3. The elasticity of the torsion spring and the adsorption of the neodymium magnets 404 allow the multiple plate bodies 401 to form a flat part together. The semicircular grooves 405 on the adjacent plate bodies 401 form a circle together. The fruit raw materials can fall into the circular space formed by the semicircular grooves 405 between the two plate bodies 401 to obtain a certain limiting effect and can move together with the plate bodies 401, as shown in Figure 2 The arrow direction is the moving direction of the fruit on the receiving plate 4. After the fruit moves to the position adjusting assembly 5, the rubber rotating belt 503 driven by the motor rotates up and down. The single rubber rotating belt 503 produces a lateral action on the fruit in the two grooves 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 through the contact with the fruit. After the longitudinal movement of the fruit contacts the rubber rotating belt 503, a certain lateral force is generated, which causes the fruit to move longitudinally and laterally, helping to adjust the position of the fruit. Then, the position of the fruit can be adjusted in this link to cooperate with the subsequent detection and positioning to help determine the position of the fruit.

[0024] Specifically, the receiving plate 4 further comprises a hard rubber ring 403 fixedly installed at the bottom of the semicircular groove 405. The top of the hard rubber ring 403 is fixedly connected with a flexible rubber pad 402. The flexible rubber pad 402 supports the fruit in the semicircular groove 405 and elastically extrudes the fruit around when the fruit is embedded in the semicircular groove 405. A plurality of neodymium magnets 404 are embedded and fixedly connected in 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 are attracted together to form a flat surface.

[0025] The flexible rubber pads 402 between the adjacent two plate bodies 401 are jointly filled in the semicircular groove 405 to support the fruit. The hard rubber ring 403 additionally provides a certain supporting property to limit the deformation amplitude of the flexible rubber pad 402 to avoid the fruit from sinking between the multiple flexible rubber pads 402. Then, a downward force can be applied to the fruit to force the flexible rubber pad 402 to deform downward. The fruit can be clamped or limited in the semicircular groove 405 by the deformation of the flexible rubber pad 402 and the support of the hard rubber ring 403 to fix the position of the fruit, which can stably support the fruit to avoid damage to the fruit flesh caused by shaking and collision during the conveying process and can adapt to fruits of different sizes to improve the universality of the equipment.

[0026] When the plate body 401 moves to the driving roller 2, the neodymium magnets 404 between the plate bodies 401 are separated, and due to the change in angle, the plate bodies 401 are also separated, so that the fruits can be taken away from between the plate bodies 401, and the halving cutting work is performed.

[0027] Specifically, the positioning assembly 5 further comprises a mounting frame 504 fixedly installed on the top of the cross plate 502, a plurality of slot positions for the fruits to pass through are formed in the cross plate 502, and the slot positions correspond to the positions of the semicircular grooves 405 and the neodymium magnets 404; the side wall of the cross plate 502 is fixedly connected with a triangular guide frame 514, which is located between the slot positions below the cross plate 502 and is used for combing the positions of the fruits; a plurality of air cylinders I 506 are fixedly connected in the mounting frame 504, the output ends of the air cylinders I 506 are downwardly fixedly connected with moving columns 505, the bottom ends of the moving columns 505 are fixedly connected with rubber protrusions 507, a plurality of flexible capacitive sensors I 508 are fixedly connected in the circumferences of the rubber protrusions 507, the flexible capacitive sensors I 508 form a detection array and are used for detecting whether the two longitudinal ends of the fruits are distributed in an up-down manner; the moving columns 505 are fixedly sleeved with a fixed frame 509, the side plates of the fixed frame 509 are fixedly connected with electromagnets I 512, the electromagnets I 512 are connected with vertical plates 510 through magnetic adsorption, the bottom ends of the vertical plates 510 are fixedly connected with inclined elastic plates 511, a plurality of springs are fixedly connected between the vertical plates 510 and the inclined elastic plates 511, the vertical plates 510 and the inclined elastic plates 511 can be slidably penetrated through the cross plate 502, and the slot position side walls of the cross plate 502 are fixedly connected with elastic rubber pads 513 corresponding to the vertical plates 510 and the inclined elastic plates 511; when the vertical plates 510 and the inclined elastic plates 511 are lowered, the elastic rubber pads 513 are inserted, so that the elastic rubber pads 513 are expanded in the direction of the rubber rotating belt 503, the contact between the fruits and the rubber rotating belt 503 is increased, and the fruits are driven to rotate in the up-down position by the rotating rubber rotating belt 503.

[0028] The plurality of cylinders 506 are arranged along the moving direction of the fruits, and are directly above the slots of the horizontal plate 502. The plurality of cylinders 506 are controlled by the program to perform repeated up and down movements in sequence, forming a wave-like movement. The moving column 505 below the cylinder 506 does not move synchronously downward. When the flexible capacitive sensor 508 on the rubber protrusion 507 contacts the stem or "butt" part of the fruit, the position of the fruit can be detected through the change in capacitance. When the rubber protrusion 507 can extend into the two end recesses of the fruit, the flexible capacitive sensor 508 can only contact the fruit, thus it can roughly determine that one end of the fruit has been moved upward. At the same time, when the moving column 505 is driven to descend by the cylinder 506, the fixed frame 509 also descends 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 are inserted between the elastic rubber pad 513 and the slots of the horizontal plate 502, causing the elastic rubber pad 513 to expand towards the rubber rotating belt 503, forcing the fruit to move towards the rubber rotating belt 503, increasing the contact between the fruit and the elastic rubber pad 513, and allowing the fruit to move stably in multiple directions. The plurality of elastic rubber pads 513 work together to make the fruit rotate as much as possible. After the flexible capacitive sensor 508 below one of the cylinders 506 detects the fruit, the electromagnet 512 behind the cylinder 506 is powered off. The subsequent cylinders 506 still perform up and down reciprocating motion, but the vertical plate 510 loses the adsorption effect of the electromagnet 512 and cannot continue to descend with the moving column 505. The vertical plate 510 and the inclined elastic plate 511 can pass through the slot opened on the fixed frame 509, and 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 pad 513, and the fruit loses contact with the rubber rotating belt 503, avoiding changes in the position of the fruit. On the other hand, the subsequent cylinders 506 continue to move up and down, which can help to determine the position of the fruit to some extent, and also to continuously detect whether the position of the fruit has deviated.

[0029] The triangular shape of the triangular guide frame 514 between the two slots forms a horn shape on both sides of the slots, so that the fruits can be guided into the slots of the horizontal plate 502, i.e. near the position of the semicircular slot 405, helping to adjust the position of the fruits.

[0030] Specifically, the top of the conveying belt support 1 is provided with an upper positioning and pressing assembly 6 for detecting the position of the fruit, which comprises a mounting seat 601 fixedly installed on the top of the conveying belt support 1, the bottom of the horizontal plate of the mounting seat 601 is fixedly connected with a plurality of bases 602, the bottom of each base 602 is symmetrically rotatably connected with a second air cylinder 603, the output end of each second air cylinder 603 faces downward and is rotatably connected with a rubber contact block 604, the two rubber contact blocks 604 are symmetrically distributed and fixedly connected with a pressing plate 610 on the side close to each other, one side of the pressing plate 610 is fixedly connected with a rubber sharp block 605, the rubber sharp block 605 is in contact with the inner side of the two longitudinal ends of the fruit, the outer side of the rubber sharp block 605 is fixedly embedded with a flexible capacitive sensor two 606 for detecting the position of the longitudinal end of the fruit.

[0031] The fruit then moves with the plate body 401 and moves below the rubber sharp block 605, the rubber sharp block 605 moves downward under the drive of the second air cylinder 603, the arc-shaped surface of the two rubber sharp blocks 605 is provided with the flexible capacitive sensor two 606, when the two flexible capacitive sensor two 606 contacts the end recess of the fruit, only one of the two flexible capacitive sensor two 606 can detect the fruit through the change of the capacitance after the contact, the fruit has been roughly in the position with the end recess upward after passing through the positioning assembly 5, so that the position of the fruit is detected, and at the same time, the downward movement of the two rubber sharp blocks 605 can generate downward pressure on the fruit from top to bottom.

[0032] Specifically, the bottom of each base 602 is fixedly connected with an extension rod 607, the bottom end of each extension rod 607 is fixedly connected with a double-sided electromagnet 608, the double-sided electromagnet 608 generates a magnetic attraction force on the pressing plate 610, the two pressing plates 610 are rotatably connected with a rotating connection head 609 between them, the rotating connection head 609 has protrusions at both ends and slides between the two pressing plates 610 to limit the position between the two pressing plates 610, and the protrusions of the rotating connection head 609 prevent the two pressing plates 610 from separating left and right.

[0033] After the fruit is detected by the flexible capacitive sensor two 606, i.e. after the end recess of the fruit is distributed upward, the double-sided electromagnet 608 is powered off while the second air cylinder 603 continues to move downward, the two pressing plates 610 will rotate outward under the continuous pressure of the second air cylinder 603, so that the rubber contact blocks 604 and the rubber sharp blocks 605 on both sides are opened to the sides and cover above the fruit, and then the two rubber sharp blocks 605 continuously press the fruit downward, forcing the flexible rubber pads 402 between the two plate bodies 401 to deform downward, under the elastic support of the flexible rubber pads 402 and the limitation of the hard rubber ring 403, the fruit can be clamped in the semicircular groove 405, so that the position of the fruit can be limited to avoid the change of the position of the fruit due to inertia when the fruit moves with the receiving plate 4.

[0034] It should be noted that when the two pressing plates 610 are attracted to each other by the magnetic attraction of the bidirectional electromagnet 608, the two air cylinders 603 should be slightly open outward, so that when the bidirectional electromagnet 608 is powered off, the air cylinder 603 can generate an outward pushing force on the rubber sharp block 605 at this angle, avoiding the pushing force of the air cylinder 603 on the rubber sharp block 605 being perpendicular downward after the bidirectional electromagnet 608 is powered off. When the air cylinder 603 retracts, it also brings the rubber sharp block 605 back to the original position, and then the bidirectional electromagnet 608 is started to attract the two pressing plates 610 together to complete the resetting work, or a magnet can be embedded in the position where the two pressing plates 610 are attracted by the bidirectional electromagnet 608. When the rubber sharp block 605 needs to be opened, the magnetism of the bidirectional electromagnet 608 is reversed, and the repulsive force is used to rotate the two pressing plates 610 outward.

[0035] Specifically, the conveying belt support 1 is fixedly connected with a fixed plate 8, the top of the fixed plate 8 is fixedly connected with a stem pulling positioning assembly 7 corresponding to the upper positioning and pressing assembly 6, the stem pulling positioning assembly 7 is used to detect the position of the fruit from below and remove the fruit stem, and comprises a bottom plate 701 fixedly installed on the top of the fixed plate 8, the top of the bottom plate 701 is fixedly connected with an electric push rod 702, the output end of the electric push rod 702 faces upward and is fixedly connected with a mounting shell 703, the mounting shell 703 is fixedly connected with a stepping motor 704, the rotating shaft top end of the stepping motor 704 is fixedly connected with a bidirectional double-rod air cylinder 705, the two moving ends of the bidirectional double-rod air cylinder 705 are fixedly connected with symmetrically distributed moving blocks 706, the side close to each other of the two moving blocks 706 is fixedly connected with hard stem pulling blocks 707, the top of the moving block 706 has an arc contact surface, and a flexible capacitive sensor three 708 is fixedly connected in the arc contact surface.

[0036] The bottom plate 701 can be between the conveying belt supports 1, i.e. below the fruit, or can be distributed above the conveying belt supports 1, i.e. above the fruit, or the bottom plate 701 is arranged above and below the fruit, if the electric push rod 702 is below the upper positioning and pressing assembly 6, the electric push rod 702 needs to act together with the rubber rotating belt 503, and simultaneously performs positioning action on both ends of the fruit, this mode is suitable for apples, pears and other fruits, if it is suitable for peach fruits, the bottom plate 701 should be above the fruit, and the electric push rod 702 should drive the bidirectional double-rod air cylinder 705 to move downward from top to bottom, so as to facilitate contacting the end recess of the fruit and clamping the fruit stem by the two hard stem pulling blocks 707.

[0037] When the flexible capacitive sensor three 708 is driven by the electric push rod 702 to move towards the fruit, the two moving ends of the bidirectional double-rod pneumatic cylinder 705 are separated, the flexible capacitive sensor three 708 at the end of the moving block 706 contacts the recessed portion, then the two moving ends of the bidirectional double-rod pneumatic cylinder 705 are immediately close, the hard stem pulling block 707 is used to quickly clamp the fruit stem, and the stepping motor 704 is quickly rotated for several turns, so that the fruit stem is twisted off, then the output end of the electric push rod 702 is retracted, so that the fruit stem is removed, and then when the moving block 706 is reset under the driving of the bidirectional double-rod pneumatic cylinder 705, the fruit stem can be naturally loosened. It should be noted that when the moving block 706 is below the fruit, the fruit is limited by the flexible rubber pad 402 and the hard rubber ring 403 when the fruit stem is pulled out by the retraction of the electric push rod 702, so that the fruit cannot move downward and the fruit stem can be successfully pulled out. In the step of pulling out the fruit stem, the pneumatic cylinder two 603 should have been moved downward and moved upward to return to the original position, so that when the fruit is driven by the receiving plate 4, the fruit stem is pulled out without being limited from above and below at the same time, so as to avoid damage to the fruit. When the moving block 706 is above the fruit, it must be behind the upper positioning and pressing assembly 6, and after the fruit is clamped in the flexible rubber pad 402 and the hard rubber ring 403, the stem pulling action is performed, so as to avoid the position deviation of the fruit during the stem pulling.

[0038] The above examples are only used to illustrate the technical solutions of the present application, but not limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent ones; and these modifications or replacements will not change the essence of the corresponding technical solutions out of the protection scope of the technical solutions of the embodiments of the present application.
