Specifically, in the first position, the flipping plate 34 abuts one of the first limit bumper blocks 36, while the second locking roller 322 is locked to the second channel 352 to limit bouncing of the flipping plate 34.

It will be appreciated that when the flipping panel 34 has just been rotated to the first position shown in fig. 9, the first limit bumper 36 will exert a reaction force on the flipping panel 34, thereby causing the flipping panel 34 to have a tendency to rebound. However, since the second locking roller 322 is locked to the second channel 352, the second locking roller 322 interferes with the rotation of the second channel 352, i.e., the channel plate 35, thereby restricting the rebound of the flipping plate 34.

Referring to fig. 11-13, in the second position, the first locking roller 321 is locked to the first channel 351, while the third locking roller 323 is locked to the third channel 353 to limit rotation of the roll-over plate 34.

It will be appreciated that in the second position, if the center of gravity of the carrier plate 2 is shifted due to the bias of the article to be carried, and further the carrier plate 2 tends to rotate leftwards or rightwards, the first locking roller 321 is locked to the first channel 351, and the third locking roller 323 is locked to the third channel 353, so that the first locking roller 321 and the third locking roller 323 limit the rotation of the channel plate 35, thereby limiting the rotation of the flipping plate 34, and finally limiting the rotation of the carrier plate 2 in the carrying state.

In particular, referring to fig. 15 and 16, in the third position, the second locking roller 322 is locked to the second channel 352 to limit bouncing of the flipping panel 34.

Referring to fig. 15 and 16, in the third position, the flipping plate 34 abuts against the other first limit bumper 36 and the second locking roller 322 is locked to the second channel 352 to limit bouncing of the flipping plate 34.

It will be appreciated that when the flipping panel 34 has just been rotated to the third position shown in fig. 15, the other first limit bumper 36 will exert a reaction force on the flipping panel 34, thereby causing the flipping panel 34 to have a tendency to rebound. However, since the second locking roller 322 is locked to the second channel 352, the second locking roller 322 interferes with the rotation of the second channel 352, i.e., the channel plate 35, thereby restricting the rebound of the flipping plate 34.

Specifically, taking the orientation shown in fig. 11 as an example, the first time needle direction is clockwise, and the second time needle direction is counterclockwise.

Specifically, in fig. 10, 12, 13 and 16, the solid line indicates the actual position; the dashed lines represent virtual movement trends.

More specifically, during the rotation of the flipping plate 34 from the second position shown in fig. 11 to the first position shown in fig. 9, the second locking roller 322 moves within the second channel 352 until the second locking roller 322 abuts against the left side wall of the second channel 352 when the flipping plate 34 rotates to the first position.

Specifically, during the rotation of the flipping plate 34 from the second position shown in fig. 11 to the third position shown in fig. 15, the second locking roller 322 rolls in the second channel 352 until the flipping plate 34 rotates to the third position, and the second locking roller 322 abuts against the right side wall of the second channel 352.

For example, when the flipping plate 34 is flipped from the loading state of the second position to the unloading state of the first position, i.e. the flipping plate 34 rotates clockwise as shown in fig. 11 to the first position as shown in fig. 9, the flipping plate 34 is subjected to a reaction force in the second clockwise direction due to the sudden abutment with the first limit bumper 36, i.e. after the flipping plate 34 is flipped to abut against one of the first limit bumper 36, the flipping plate 34 has a bouncing tendency.

If the overturning plate 34 is overturned to abut against the first limiting buffer block 36, the overturning plate 34 bounces, so that the actual falling track of the article to be sorted deviates from the designed falling track when the overturning plate 34 is unloaded, and the actual falling time deviates from the designed falling time, thereby affecting the falling speed and the falling precision of the article to be sorted.

In the present embodiment, referring to fig. 9 and 10, in the first position, the flipping plate 34 abuts against a first limit buffer block 36, and the second locking roller 322 is locked in the second channel 352 to limit the rotation of the flipping plate 34, so as to avoid the bouncing of the flipping plate 34, and ensure that the articles to be sorted accurately and quickly fall to the set position.

In further detail, referring to fig. 10, when the flipping plate 34 has a bouncing tendency in the counterclockwise direction, the flipping plate 34 also drives the channel plate 35 fixedly connected to the flipping plate 34 to have a bouncing tendency in the counterclockwise direction; however, since the output shaft of the driving member 31 is in a stationary state at this time, the driving plate 32 fixedly connected to the output shaft of the driving member 31 is also kept stationary, and the axes of the first locking roller 321, the second locking roller 322, and the third locking roller 323 provided on the driving plate 32 are not shifted, and the second locking roller 322 is locked to the second channel 352 while the inversion plate 34 abuts against one of the first limit buffers 36, the rebound of the inversion plate 34 is restricted.

For example, referring to fig. 11-13, the carrier plate 2 is in a loaded state when the flipping plate 34 is in the second position. The upper edge of the turnover plate 34 extends horizontally, at this time, the carrying plate 2 is in a carrying state, the articles to be sorted are placed on the carrying plate 2, at this time, the output shaft of the driving member 31 is fixed and not rotated, the driving plate 32 fixedly connected with the output shaft of the driving member 31 is not rotated, the axial positions of the first locking roller 321, the second locking roller 322 and the third locking roller 323 are not changed, the first locking roller 321 is locked in the first channel 351, the third locking roller 323 is locked in the third channel 353, and the rotation of the turnover plate 34 is limited. At this time, even if the center of gravity of the loading plate 2 deviates due to uneven stress, the loading plate 2 can be locked, and the stable state of the loading plate 2 is ensured.

Specifically, taking the view of fig. 12 as an example, at this time, if the carrier plate 2 has a tendency to rotate clockwise, that is, the flipping plate 34 has a tendency to rotate clockwise, the first locking roller 321 is locked and abutted with the first channel 351, and the third locking roller 323 is locked and abutted with the third channel 353, so as to limit the right rotation of the flipping plate 34. It will be appreciated that the channel plate 35 fixedly attached to the flipping plate 34 has a tendency to turn left when the flipping plate 34 has a tendency to turn right. Since the first locking roller 321 and the third locking roller 323 both maintain the axial position, if the channel plate 35 has a clockwise rotation tendency, the right side wall of the first channel 351 will abut against the first locking roller 321, and the right side wall of the third channel 353 will abut against the third locking roller 323, so as to limit the clockwise rotation of the channel plate 35.

Taking the view of fig. 13 as an example, at this time, if the carrier plate 2 has a tendency to rotate in a counterclockwise direction, that is, the flipping plate 34 has a tendency to rotate in a counterclockwise direction, the first locking roller 321 is locked and abutted with the first channel 351, and the third locking roller 323 is locked and abutted with the third channel 353, so as to limit the left rotation of the flipping plate 34. It will be appreciated that when the flipping panel 34 has a tendency to rotate in a counter-clockwise direction, the channel panel 35 fixedly connected to the flipping panel 34 also has a tendency to rotate in a counter-clockwise direction. Since the first locking roller 321 and the third locking roller 323 both maintain the axial position, if the channel plate 35 has a tendency to rotate in the counterclockwise direction, the left side wall of the first channel 351 will abut against the first locking roller 321, and the left side wall of the third channel 353 will abut against the third locking roller 323, thereby restricting the rotation of the channel plate 35.

For example, when the flipping plate 34 is flipped from the loading state of the second position to the unloading state of the third position, that is, when the flipping plate 34 is rotated in the counterclockwise direction shown in fig. 11 to the third position shown in fig. 15, the flipping plate 34 is suddenly abutted against the other first limit bumper 36, so that the flipping plate 34 receives a reaction force in the clockwise direction, that is, after the flipping plate 34 is flipped to abut against the other first limit bumper 36, the flipping plate 34 has a bouncing tendency.

If the overturning plate 34 is overturned to abut against another first limiting buffer block 36, the overturning plate 34 bounces, so that the actual falling track of the articles to be sorted deviates from the designed falling track when the overturning plate 34 is unloaded, and the actual falling time deviates from the designed falling time, thereby affecting the falling speed and the falling precision of the articles to be sorted.

In the third position, referring to fig. 15 and 16, the second locking roller 322 is locked in the second channel 352, and the overturning plate 34 abuts against the other first limiting buffer block 36, so that the rebound of the overturning plate 34 is limited, and the objects to be sorted can be accurately and quickly dropped to the set position.

Further specifically, referring to fig. 16, when the flipping plate 34 has a rebound tendency in the clockwise direction, the flipping plate 34 also drives the chute plate 35 fixedly connected to the flipping plate 34 to have a rebound tendency in the clockwise direction; however, since the output shaft of the driving element 31 is in a stationary state at this time, the driving plate 32 fixedly connected to the output shaft of the driving element 31 is also kept stationary, and the axes of the first locking roller 321, the second locking roller 322, and the third locking roller 323 provided on the driving plate 32 are not offset, since the second locking roller 322 is locked in the second channel 352, and the flipping plate 34 abuts against the other first limit buffer block 36, and thus the bouncing of the flipping plate 34 is limited.

In fig. 9 to 16, the drive plate 32 is not shown, and only the positional relationship between the first lock roller 321, the second lock roller 322, and the third lock roller 323 and the tunnel plate 35 is shown.

In particular, referring to fig. 9-16, in the present embodiment, two opposite side walls of the second channel 352 are each provided with a second locking protrusion 3521 capable of locking abutment with the second locking roller 322, and in the first position and the third position, the second locking roller 322 is locked in abutment with the two second locking protrusions 3521, respectively.

Referring to fig. 9, in the first position, the second locking roller 322 is locked in abutment with the second locking projection 3521 on the left side, limiting bouncing of the flipping panel 34. Referring to fig. 15, in the third position, the second locking roller 322 is locked in abutment with the second locking projection 3521 on the right side, limiting bouncing of the flipping panel 34.

It will be appreciated that after the output shaft of the control drive 31 is rotated in place in the set clockwise direction, the carrier plate 2 is tilted relative to the horizontal plane, and the articles to be sorted slide down the carrier plate 2 quickly. In order not to affect the falling speed of the articles to be sorted, the rebound of the carrier plate 2 should be limited as much as possible after the carrier plate 2 is turned in place. In the present embodiment, in both the first position and the third position, the turning of the flipping panel 34 is restricted, thereby restricting the rebound of the loading panel 2 and ensuring the rapid drop of the articles to be sorted.

Specifically, in the present embodiment, the process when the flipping plate 34 is flipped from the loading state shown in fig. 11 to the unloading state shown in fig. 9 is as follows: in the initial state shown in fig. 11, the driving plate 32 rotates, the third locking roller 323 moves out of the third channel 353, the first locking roller 321 rolls along the first channel 351 and presses the side wall of the first channel 351, so that the channel plate 35 is pressed, the channel plate 35 rotates clockwise, and the turning plate 34 rotates clockwise; as the drive plate 32 continues to rotate, the second locking roller 322 always moves in the second channel 352; when the flipping plate 34 rotates to abut against one of the first limit bumper blocks 36, the second locking roller 322 is also locked to abut against the second locking protrusion 3521 on the left side of the second channel 352, as shown in fig. 9, thereby limiting the bouncing of the flipping plate 34. Fig. 14 is a schematic view showing a state in which the flipping plate 34 is flipped from the loading state shown in fig. 11 to the unloading state shown in fig. 9.

Specifically, in the present embodiment, the process when the flipping plate 34 is flipped from the loading state shown in fig. 11 to the unloading state shown in fig. 15 is as follows: in the initial state shown in fig. 11, the driving plate 32 rotates, the first locking roller 321 moves out of the first channel 351, the third locking roller 323 rolls along the third channel 353 and presses the side wall of the third channel 353, so as to press the channel plate 35, so that the channel plate 35 rotates in the counterclockwise direction, and the turning plate 34 is driven to rotate in the counterclockwise direction; as the drive plate 32 continues to rotate, the second locking roller 322 always moves in the second channel 352; when the flipping plate 34 rotates to abut against the other first limit bumper 36, the second locking roller 322 is also locked to abut against the second locking protrusion 3521 on the right side of the second channel 352 as shown in fig. 15, thereby limiting the bouncing of the flipping plate 34.

Optionally, a first pressing protrusion 3511 that is matched with the first locking roller 321 is disposed in the first channel 351, and the first locking roller 321 can press the first pressing protrusion 3511 to drive the channel plate 35 to rotate along the first time pin direction; and/or

The third channel 353 is provided with a second pressing protrusion 3531 engaged with the third locking roller 323, and the third locking roller 323 can press the second pressing protrusion 3531 to drive the channel plate 35 to rotate in the second clockwise direction.

Preferably, the first pressing protrusion 3511 is disposed at an intermediate position of the stroke of the first locking roller 321.

Specifically, taking the orientation shown in fig. 11 as an example, in the process that the first locking roller 321 rolls along the first channel 351 while pressing down the side wall of the first channel 351, the first locking roller 321 presses down the left side wall of the upper half of the first channel 351, then presses down the first pressing protrusion 3511, and finally presses down the right side wall of the lower half of the first channel 351.

Preferably, the second pressing protrusion 3531 is disposed at a middle position of the stroke of the third locking roller 323.

Specifically, taking the orientation shown in fig. 11 as an example, in the process that the third locking roller 323 rolls along the third channel 353 while pressing down the side wall of the third channel 353, the third locking roller 323 presses down the right side wall of the upper half of the third channel 353, then presses down the second pressing protrusion 3531, and finally presses down the left side wall of the lower half of the third channel 353.
