Taking the processing of the apple a as an example, the fruit shaft adjusting mechanism 1, the positioning and transferring mechanism D, the fruit peeling mechanism 5 and the fruit dicing mechanism 6 in the fruit processing equipment will be specifically described.

First, fruit shaft adjusting mechanism 2 and positioning and transferring mechanism D

Fruit positioning mechanism 7 includes movable mounting panel 71 and clamping device 72, and fruit shaft adjusting mechanism 2 establishes at mounting panel 71 front side and the center pin X of fruit shaft adjusting mechanism 2 is coaxial with the center pin of mounting panel 71, and the fruit that is used for placing apple A places the position and establishes in mounting panel 71 front side center pin department, and clamping device 72 can the centre gripping put on fruit shaft adjusting mechanism 2 and aim at the apple A that the fruit placed the position. The fruit positioning mechanism 7 is disposed between the two shaft brackets 81 of the steering driving mechanism 8, and two ends of the mounting plate 71 are respectively mounted on the two shaft brackets 81 of the steering driving mechanism 8 in a coaxial (steering shaft T) rotatable manner, so that the mounting plate 71 can drive the fruit shaft adjusting mechanism 2 and the apple a to rotate together with the horizontal steering shaft T about the shaft brackets 81 of the steering driving mechanism 8. The two horizontally arranged and mutually symmetrical slide rails 91 of the traverse driving mechanism 9 are respectively arranged on the inner walls of the two side plates 11 of the frame 1, the steering driving mechanism 8 is arranged between the two slide rails 91, and the two mutually symmetrical rotating shaft frames 81 of the steering driving mechanism 8 are respectively arranged on the two slide rails 91 through sliding blocks, so that the steering driving mechanism 8 can slide along the slide rails 91.

Initially, the controller controls the positioning and transferring mechanism D to transfer the fruit shaft adjusting mechanism 2 to the starting end S in fig. 1, and the central axis X of the fruit shaft adjusting mechanism 2 is aligned with the camera 13 erected above the starting end S. The controller controls the robot (not shown) to feed the apples a onto the fruit-spindle-adjusting mechanism 2. The controller controls the camera 13 as an image capturing unit to shoot the apple A placed on the fruit shaft adjusting mechanism 2 in alignment, and controls the shaft adjusting action of the fruit shaft adjusting mechanism 2 according to the shot fruit image.

The fruit shaft adjusting mechanism 2 comprises three positioners P (P1, P2, P3) uniformly distributed along a circumference with a center axis X of the fruit shaft adjusting mechanism 2 as a center, each positioner P is fixedly arranged on the mounting plate 71 through two groups of symmetrically arranged support assemblies 21, outer surfaces of the crawler belts 27 of the three positioners P (P1, P2, P3) facing the center axis X are inclined outwards at the same angle, so that the apple a can be positioned at a fruit placing position aligned with the center axis X of the fruit shaft adjusting mechanism 2 when being held together by the crawler belts 27 of the three positioners P (P1, P2, P3), the outer surfaces of the crawler belts 27 serve as rotating friction members to provide friction force for the fruit self-rotating shaft adjusting mechanism, and the three positioners P (P1, P2, P3) are used for shaft adjusting of the apple a together. Install spacing layer board 20 between two adjacent position adjusters P, every position adjuster P can both rotate relative fruit shaft adjusting mechanism 2's center pin X for the distance of each position adjuster P to center pin X changes. The minimum distance from the limiting supporting plate 20 to the central axis X of the fruit shaft adjusting mechanism 2 is between the minimum distance and the maximum distance from each position adjuster P to the central axis X, and the apples A can be prevented from falling from an inner ring surrounded by the three position adjusters P (P1, P2 and P3). The top of the limiting supporting plate 20 is inclined towards the direction far away from the central axis X to form a supporting section 201, so that the apple A is prevented from falling between the two positioners P.

The exploded structure of the positioner P is shown in fig. 6, the two bodies 22 are transmission plates which are oppositely arranged and synchronously rotate, a driving wheel 25 is arranged at the position close to the middle section between the two bodies 22, a transmission mounting plate 221 is arranged at the position on the left body 22 opposite to the driving wheel 25, and a shaft adjusting motor 24 is arranged on the transmission mounting plate 221 and drives the driving wheel 25 to rotate; the upper and lower sections between the two bodies 22 are provided with a synchronizing wheel assembly 26, and a crawler belt 27 is wound around the periphery of the area enclosed by the drive wheel 25 and the two synchronizing wheel assemblies 26. The lower part of the figure shows the installation structure of the synchronous rotating wheel assembly 26, the upper part of the figure shows the disassembly structure of the synchronous rotating wheel assembly 26, the synchronous rotating wheel assembly 26 comprises a driven wheel 261 serving as a rotating friction piece (synchronous rotating wheel), the driven wheel 261 is empty at the shaft position, a friction driving connecting piece 263 extends into the shaft position of the driven wheel 261, two sleeves 262 with the inner wall cross sections being circumferences are respectively inserted between the driven wheel 261 and the friction driving connecting piece 263 from two ends of the shaft position of the driven wheel 261, so that the sleeves 262 are sleeved on the friction driving connecting piece 263 and sleeved on the driven wheel 261, the cross sections of the parts, sleeved and contacted by the sleeves 262, on the friction driving connecting piece 263 are circular, the driven wheel 261, the sleeves 262 and the friction driving connecting piece 263 are coaxially arranged, and the sleeves 262 are in rotating friction contact with the friction driving connecting piece 263 and the driven wheel 261. The two ends of the friction driving connecting piece 263 respectively extend out of the two ends of the axial position of the driving wheel 261 towards the body 22 and are fixedly connected with the body 22, and the cross section of the part where the friction driving connecting piece 263 is fixed with the body 22 is square or other shapes except circular.

The two bodies 22 are respectively mounted on two sets of supporting components 21 which are oppositely arranged, the lower right side of the drawing shows an exploded structure of the supporting components 21, the supporting components 21 comprise a supporting seat 211, an adjusting shaft 212, a supporting torsion spring 213 and a pressing block 214, the lower left side of the drawing shows an assembling structure of the supporting components 21, and the adjusting shaft 212 passes through the supporting seat 211 and can rotate relative to the supporting seat 211 by taking an adjusting rotating shaft W as an axis. The positioning rotation shaft W is parallel to the axes of the driving wheel 25 and the two driven wheels 261, but not in the same plane. One end of the positioning shaft 212 is fixed on the body 22, the other end of the positioning shaft 212 extends towards the direction of the supporting seat 211 far away from the body 22, a pressing block 214 rotating along with the positioning shaft 212 is fixed at the end part of the left end of the positioning shaft 212, and two support legs of the supporting torsion spring 213 are respectively fixed on the outer side of the supporting seat 211 far away from the body 22 and the pressing block 214, so that the body 22 is installed on the supporting seat 211 in a hinged mode through the supporting torsion spring 213. The body 22 deflects towards the Z direction relative to the support base 211 under the action of gravity G, the positioning shaft 212 and the pressing block 214 fixed at the end of the positioning shaft 212 deflect towards the Z direction together under the driving of the body 22, the support leg of the support torsion spring 213 fixed on the pressing block 214 deflects towards the Z direction together with the pressing block 214, the support torsion spring 213 is twisted and deformed to apply a reverse supporting force F to the pressing block 214, the more the pressing block 214 deflects towards the Z direction, the more the degree of the torsion deformation of the support torsion spring 213 is, and the larger the reverse supporting force F applied to the pressing block 214 is. This counter-support force F on the pressing piece 214 is transmitted to the body 22 via the positioning shaft 212, preventing the body 22 from deflecting further until the counter-support force F and the force of gravity G on the body 22 are balanced, the body 22 is obliquely arranged on the supporting seat 211, and the caterpillar 27 inclines with the body 22 to support the fruit.

The controller controls the camera 13 in fig. 1 and 4 to shoot towards the apple a to obtain a posture image of the apple a, and the obtained image is analyzed by using a camera calibration algorithm (or other image recognition technologies) in the prior art, so that size data such as the position state of the central axis O of the kernel of the apple a, the length L from the stem end to the pedicle end of the apple a, the profile curve of the outer contour of the fruit peel and the like are obtained. The controller controls the rotation directions of the three positioners P according to the current position state of the kernel central axis O of the apple A, so that the kernel central axis O of the apple A is vertically arranged and is overlapped with the central axis X of the fruit shaft adjusting mechanism 2 as much as possible.

As shown in fig. 5, the apple a is placed with its stem end facing downward to the right and its stem end facing away from the stem end facing upward to the left, and the kernel center axis O is inclined upward to the left with respect to the center axis X. The controller controls the positioner P1 to adjust the axes of the apple A in the Z direction and the positioner P2 to adjust the axes of the apple A in the Z' direction.

The position adjuster P1 adjusts the axes of the apples A in the Z direction, as shown in FIG. 6, the axis adjusting motor 24 drives the driving wheel 25 to rotate in the Z direction, and the caterpillar track 27 is driven by the driving wheel 25 to move around the Z direction; the two driven wheels 261 are driven by the caterpillar 27 to synchronously rotate along the Z direction, the driven wheels 261 rotate relative to the sleeves 262 and provide a driving friction force f towards the Z direction for the sleeves 262, the sleeves 262 transmit the driving friction force f towards the Z direction to the friction driving connecting piece 263, and one end of the friction driving connecting piece 263 fixed on the body 22 drives the body 22 to rotate in the same direction. The body 22 receives the common acting force C which drives the friction force F and the component of the gravity G in the direction, the common acting force C makes the body 22 drive the adjusting shaft 212 and the pressing block 214 to continuously deflect in the Z direction, the pressing block 214 drives the supporting torsion spring 213 which is in the torsional deformation state to continuously twist, the reverse supporting force F applied to the pressing block 214 by the supporting torsion spring 213 is increased accordingly, until the reverse supporting force F and the common acting force C received by the body 22 reach a balance, and the body 22 does not deflect in the Z direction any more.

The positioner P2 adjusts the axes of the apple a in the Z 'direction, the axis-adjusting motor 24 drives the driving wheel 25 to rotate in the Z' direction, the driven wheel 261 provides a driving friction force f 'in the Z' direction, and the driving friction force f 'is opposite to the action direction of the gravity G on the body 22, so that the friction drives the connecting piece 263 to drive the body 22 to rotate in the Z' direction. The pressing piece 214 rotates along with the body 22 in the direction Z ', the supporting torsion spring 213 rotates to reduce the degree of torsional deformation, and the reverse supporting force F applied to the pressing piece 214 by the supporting torsion spring 213 decreases until the common acting force C' applied to the body 22 together with the driving friction force F 'is balanced with the acting force of the gravity G on the body 22, and the body 22 no longer deflects in the direction Z'.

The size of the driving friction force f limits the limit angle of the body 22 which can rotate relative to the supporting seat 211 when the position adjuster P adjusts the shaft, and the driving friction force f of the position adjuster P is small, so that the body 22 can only rotate relative to the supporting seat 211 by a small angle. Furthermore, a limiting rod 23 is fixedly connected to one side of the body 22 facing the supporting seat 211, a sliding slot 2111 matched with the limiting rod 23 is formed in one side of the supporting seat 211 facing the body 22 (the limiting rod 23 can also be fixed on the supporting seat 211, and the sliding slot 2111 is formed in the body 22), the limiting rod 23 extends into the sliding slot 2111 and can slide in the sliding slot 2111 in a reciprocating manner along with the rotation of the body 22, and the sliding distance of the limiting rod 23 in the sliding slot 2111 limits that the body 22 can only rotate at a small angle relative to the supporting seat 211.

It can be seen from the above that, when the track 27 of the positioner P drives the fruit to rotate, the body 22 of the positioner P can be provided with a driving force in the same direction, so that the body 22 rotates relative to the support base 211 at a small angle in the same direction as the track 27 to drive the track 22 to generate a vertical displacement along the direction, and the track 27 additionally provides the fruit with a displacement trend in the same direction, so that the fruit is not easy to slip. In fig. 7, 7(a) to 7(b) show that when the positioning device P1 adjusts its axis in the Z direction, the caterpillar 27 moves the fruit in the Z direction away from the central axis X and tends to move vertically upwards; conversely, when the positioning device P2 is adjusted in the direction Z ', the tracks 27 move the fruit in the direction Z' to a position close to the central axis X and have a downward vertical movement tendency, as shown in fig. 7(b) to 7 (a). When the positioners P1 and P2 in fig. 5 adjust the axis of the apple a, the lower right stem end of the apple a rotates downward toward the center axis X, and the upper left pedicle end of the apple a rotates upward toward the center axis X, so that the apple a is gradually adjusted toward the vertical center axis O. The above-mentioned process of adjusting the axes of the apple a is only a simplified example, and the specific control program may be adaptively designed by using a control algorithm such as a fuzzy PID algorithm in the prior art, which is not described herein again.

After the apple a is adjusted to the central axis O of the kernel of the fruit to be erected, the controller controls the positioners P1 and P2 to stop adjusting the axis of the apple a, the positioners P1 and P2 refer to fig. 6, the axis-adjusting motor 24 does not drive the driving wheel 25 to rotate any more, the caterpillar 27 does not move any more, so the driven wheel 261 does not provide driving friction any more, the reverse supporting force F and the acting force of the gravity G on the body 22 reach balance again, the body 22 drives the caterpillar 27 to restore the state of being obliquely arranged on the supporting seat 211 before adjusting the axis, and the apple a supported by the caterpillar 27 is driven to move almost transversely, so that the central axis O of the kernel of the apple a approaches to the central axis X of the fruit axis-adjusting mechanism 2 and even coincides with the central axis X.

Under the control of the controller, the fruit positioning mechanism 7 of the positioning and conveying mechanism D enables the apple A to be positioned and placed in a mode that the axis adjustment result kernel central axis O is vertically placed. As shown in fig. 8(a), the fruit positioning mechanism 7 has a fruit placing position disposed at a front central axis X of the mounting plate 71, two clamping links 721 with the same structure of the clamping device 72 are disposed in a mirror image manner with the central axis X as an axis and rotate synchronously, and the clamping links 721 have a lever structure as follows:
