[0036] The present invention will be further described with reference to the accompanying drawings.

[0037] Embodiment 1

[0038] like Figures 1 to 13As shown, the lining automatic flipping device comprises: a flipping fixing frame 71; a lining flipping device, which is used to flip the lining, and the lining flipping devices are not less than three; a transverse moving device, which is slidably mounted on the flipping fixing frame 71, and the lining flipping device is installed on the transverse moving device; a longitudinal moving device, which is slidably mounted on the flipping fixing frame 71, and the lining flipping device is installed on the longitudinal moving device, and the transverse moving devices are symmetrically located on both sides of the longitudinal moving device.

[0039] The lateral moving device and the longitudinal moving device are arranged in a T shape, the lateral moving device is used to move along the two sides of the upper, and the longitudinal moving device is used to reciprocate along the direction of the heel. The lateral moving device and the longitudinal moving device can move the lining from above the outer side of the upper to above the inner side.

[0040] There are no less than three lining turning devices, so that the lining turning devices are arranged along the contour of the lining, ensuring that the two sides and three points of the root of the lining are driven to turn, thereby ensuring stable and complete turning of the lining.

[0041] In at least one embodiment, two liner turning devices are symmetrically mounted on the longitudinal moving device.

[0042] like Figures 1 to 7 As shown, the lining turning device includes: a lining chuck for clamping the lining; a turning lifting plate 618, the bottom of the turning lifting plate 618 is rotatably connected to the lining chuck; a turning frame 631, one end of the turning frame 631 is rotatably connected to the tail of the lining chuck; a lower turning fixture, the lower turning fixture is fixed on the turning frame 631, and is used to control whether the lining chuck is turned over; a turning base plate 612, the turning lifting plate 618 is slidably mounted on the turning base plate 612; an upper turning fixture, the upper turning fixture is mounted on the turning base plate 612, and is used to fix the position of the turning lifting plate 618 when the lining chuck is turned over to limit the turning position; and a turning cylinder 621, one end of the turning cylinder 621 is rotatably mounted on the turning base plate 612, and the other end is rotatably mounted on the turning frame 631.

[0043] The lining is flipped over above the shoe opening, so the lining needs to be lifted to the top of the shoe opening first, the flipping cylinder 621 first drives the lining clamp to rise to the flipping position, and then flips, and after the flipping is completed, the lining is inserted into the inside of the shoe opening to make the lining close to the inside of the upper, and the lining is loosened to complete the flipping of the lining, and the flipping cylinder 621 drives the lining clamp to rise above the shoe opening.

[0044] The lining chuck first clamps the edge of the lining, and the lower flipping fixture first fixes the lining chuck, the lining chuck cannot flip, the flip cylinder 621 retracts, and the lining chuck rises. When it rises to the flipping position, the upper flipping fixture fixes the flip lifting plate 618, and the lower flipping fixture releases the lining chuck. The lining chuck flips and flips the edge of the lining from a downward state to an upward state. After the flipping is completed, the upper flipping fixture releases the flip lifting plate 618, the flip cylinder 621 continues to retract, and the flip lifting plate 618 continues to rise to the highest point, straightening the lining for easy glue coating, and then the flip cylinder 621 extends to insert the lining into the inside of the shoe opening, so that the lining fits the inside of the shoe upper, and finally the flip cylinder 621 drives the lining chuck to rise above the shoe opening to facilitate the removal of the shoe upper.

[0045] The flip cylinder 621 can be used to flip the liner chuck and also realize the lifting and lowering of the liner chuck. One flip cylinder 621 realizes multiple functions, which greatly simplifies the structure, makes the structure compact, occupies less space, and is easy to control.

[0046] like Figure 8 and Fig. 9 As shown, the lining chuck includes: a fixed chuck 51, on which a pneumatic cavity 511, an air inlet hole 512 and a spring hole 515 are provided, and the pneumatic cavity 511 is communicated with the air inlet hole 512; a chuck piston 52, which is slidably inserted in the pneumatic cavity 511; a first rotating shaft 55, which is rotatably mounted on the fixed chuck 51; a second rotating shaft 56, which is rotatably mounted on the tail of the fixed chuck 51; a movable chuck 53, which is rotatably mounted on the first rotating shaft 55 and is arranged opposite to the fixed chuck 51, and the chuck piston 52 is used to drive the movable chuck 53 to be pressed on the fixed chuck 51; and an opening spring 54, which is movably inserted in the spring hole 515 and is located between the movable chuck 53 and the fixed chuck 51, and the opening spring 54 is used to drive the movable chuck 53 to open.

[0047] After the high pressure gas is introduced into the air inlet 512, the clamp piston 52 is pushed to press the movable clamp 53 onto the fixed clamp 51, thereby clamping the lining. When the air inlet 512 is exhausted, the spring 54 is opened to push the movable clamp 53 open, thereby opening the clamp. The structure is simple and compact, the space occupied is small, the control is convenient, and the shoe can be easily inserted into the shoe opening.

[0048] When the lining chuck is clamping the lining, a greater pressure can be applied, and the lining chuck can be automatically opened when the air is cut off.

[0049] The movable clamp 53 is clamped by a lever, and the clamping force is relatively large.

[0050] The first rotating shaft 56 is located in the middle of the movable chuck 53, and the opening spring 54 is close to the rotating connection, with a small elastic force, which reduces the cross-sectional area of ​​the chuck piston 52. The movable chuck 53 is clamped by a lever, and the clamping force is relatively large.

[0051] In at least one embodiment, the liner clamp can also adopt micro electric clamps or pneumatic clamps.

[0052] In at least one embodiment, the movable clamp 53 and / or the fixed clamp 51 are provided with anti-skid grooves. The anti-skid grooves increase the friction force and ensure the clamping of the lining.

[0053] In at least one embodiment, the top of the collet piston 52 is hemispherical.

[0054] The hemispherical shape has low friction, so the movable clamp 53 can be opened and closed smoothly.

[0055] In at least one embodiment, a sealing gasket and / or a sealing ring is installed on the chuck piston 53.

[0056] In at least one embodiment, a bearing is installed between the first rotating shaft 55 and the fixed clamp 51, and the first rotating shaft 55 is fixed on the movable clamp 53. Bearings are installed between the second rotating shaft 56, the flip lifting plate 618 and the fixed clamp 51.

[0057] In at least one embodiment, a first chuck positioning block 514 and a second chuck positioning block 513 are disposed on both sides of the fixed chuck 51 , and the first chuck positioning block 514 and the second chuck positioning block 513 are respectively located on both sides of the first rotating shaft 55 .

[0058] The first chuck positioning block 514 and the second chuck positioning block 513 can accurately position the lining chuck to avoid the instability of the flipping position affecting the clamping of the lining, and make the overall structure simple and stable in operation. The first chuck positioning block 514 is used to position the lining chuck in the initial state, that is, to limit the position of the lining chuck when the lining starts to be clamped, so as to ensure that the lining chuck can smoothly clamp the lining. The second chuck positioning block 513 is used to position the lining chuck after the lining is flipped after clamping the lining, so that the lining chuck is almost in a vertical state after flipping, thereby ensuring that the back of the lining can be straightened, which is convenient for spraying glue on the lining.

[0059] The lower flipping fixing device includes: a lower positioning cylinder 633, which is fixed on the flipping frame 631; and a lower positioning block 632, which is fixed on the piston rod of the lower positioning cylinder 633 and movably inserted in the lower positioning slot of the flipping frame 631. The lower positioning block 632 is used to press on the fixed clamp 51 through the lower positioning cylinder 633 to limit the rotation of the lining clamp.

[0060] The lower positioning cylinder 633 is convenient for limiting the flipping of the lining clamp through the lower positioning block 632, and has a simple structure and is easy to control.

[0061] In at least one embodiment, the lower positioning block 632 is provided with a first positioning surface 6322 and a second positioning surface 6321, the first positioning surface 6322 is used to limit the flipping of the lining chuck before the lining chuck is flipped, and the second positioning surface 6321 is used to limit the flipping of the lining chuck after the lining is flipped.

[0062] The contact area between the positioning surface and the fixing clamp 51 is large, which can effectively prevent the fixing clamp 51 from turning over after being stressed, thereby ensuring reliability.

[0063] The upper flip fixing device includes: an upper positioning cylinder 621, which is fixed on the flip base plate 612; and an upper positioning rod 620, which is fixed on the upper positioning cylinder 621 and movably inserted on the flip base plate 612. An upper flip positioning hole 6181 matching the upper positioning rod 620 is provided on the flip lifting plate 618. The upper positioning rod 620 is used to insert or pull out the upper flip positioning hole 6181 through the upper positioning cylinder 621.

[0064] The upper positioning rod 620 is inserted into the flip lift. Since the upper positioning rod 620 is also inserted into the flip bottom plate 612, the position of the flip lift plate 618 can be fixed, so that the flip cylinder 621 can be flipped.

[0065] When the lining chuck is in the initial state, the first chuck positioning block 514 is pressed against the outer side of the flip lifting plate 618, and the lower positioning block 632 is pressed against the fixed chuck 51 under the action of the lower positioning cylinder 633. The first chuck positioning block 514 and the lower positioning block 632 fix the relative position between the lining chuck and the flip frame 631, so that the lining chuck does not rotate; when the lower positioning block 632 releases the fixed chuck 51, the lining chuck can rotate. After the lining chuck is flipped, it is in a downward vertical state, and the second chuck positioning block 513 is pressed against the inner side of the flip lifting plate 618. The second chuck positioning block 513 and the lower positioning block 632 fix the relative position between the lining chuck and the flip frame 631, so that the lining chuck does not rotate.

[0066] In at least one embodiment, bearings are installed on both sides of the upper flip positioning hole 6181. The bearings can make the upper positioning rod 620 insert and remove smoothly, and the friction is small, so as to avoid the situation of getting stuck and improve the stability.

[0067] In at least one embodiment, it also includes: a first positioning plate 615, the first positioning plate 615 is fixed on the flip bottom plate 612; a second positioning plate 613, the second positioning plate 613 is fixed on the flip lifting plate 618 and is located above the first positioning plate 615; a third positioning plate 614, the third positioning plate 614 is fixed on the flip lifting plate 618 and is located below the first positioning plate 615.

[0068] The positioning plate can limit the highest and lowest positions of the lining clamp. The lowest position ensures that the edge of the lining can be clamped accurately, and the highest position stretches the lining to a straightened state to avoid the straightening position being too high and causing the position of the shoe upper to change.

[0069] Compared with the prior art in which the maximum extended position and the minimum retracted position of the cylinder are used for positioning, the positioning is more accurate and the impact on the cylinder is small.

[0070] A positioning plate is mounted on the flip bottom plate 612, and two positioning plates are mounted on the flip lifting plate 618, so that the number of positioning plates is minimized and installation and use are convenient.

[0071] The longitudinal moving device includes: a longitudinal moving seat 73, which is slidably mounted on the flipping fixed frame 71 and connected to the lining flipping device; and a longitudinal moving cylinder 76, which is fixed on the flipping fixed frame 71 and connected to the longitudinal moving seat 73; the transverse moving device includes: a transverse moving seat 74, which is slidably mounted on the flipping fixed frame 71 and connected to the lining flipping device; and a transverse moving cylinder 75, which is fixed on the flipping fixed frame 71 and connected to the transverse moving seat 74.

[0072] The longitudinal moving seat 73 and the transverse moving seat 74 are both connected to the turnover bottom plate 612 to drive the lining turnover device to move.

[0073] A longitudinal fixing seat 72 is mounted at the center of the flip fixing frame 71 , and a longitudinal moving seat 73 is slidably mounted on the longitudinal fixing seat 72 .

[0074] Specifically, the flip bottom plate 612 is respectively fixed on the longitudinal moving seat 73 and the transverse moving seat 74. The longitudinal moving seat 73 and the transverse moving seat 74 are both mounted on the flip fixing frame 71 through a linear guide pair.

[0075] During operation, the transverse moving cylinder 75 and the longitudinal moving cylinder 76 are both in a retracted state, the lining clamp is located on the outside of the upper, the upper is first fixed to the upper mold frame, the lining clamp surrounds the outside of the upper, and the lining clamp is in an open state, the edge of the lining is inserted between the fixed clamp 51 and the movable clamp 53 of the lining clamp, then the air inlet 512 is ventilated, the clamp piston 52 lifts the movable clamp 53, and the movable clamp 53 presses the lining on the fixed clamp 51. At this time, the lining clamp is in the lowest position, the upper positioning cylinder 621 is in a retracted state, the flip lifting plate 618 is in a state that it can be lifted, the lower positioning cylinder 633 is in an extended state, the lower positioning block 632 is pressed on the fixed clamp 51, the positions of the fixed clamp 51 and the flip frame 631 are relatively fixed, and the fixed clamp 51 cannot rotate around the second rotation axis 56. Then the turning cylinder 621 starts to retract. Since the relative positions of the lining clamp and the turning frame 631 are fixed, the lining clamp drives the turning lifting plate 618 to rise. When the lining clamp rises to the turning position, that is, it rises to a position not lower than the shoe mouth of the shoe upper, the turning of the lining clamp is not affected; the upper positioning cylinder 621 extends, and the upper positioning rod 620 is inserted into the upper turning positioning hole 6181 of the turning lifting plate 618. The position of the turning lifting plate 618 is fixed and cannot be raised or lowered. Then the lower positioning cylinder 633 retracts, and the lower positioning block 632 leaves the fixed clamp 51, and the fixed clamp 51 can rotate around the second rotating shaft 56. The turning cylinder 621 continues to retract, and the fixed clamp 51 is driven to rotate by the turning cylinder 621. The lining clamp is turned from the oblique upward state to the vertical downward state, completing the turning of the lining. The lower positioning cylinder 633 extends to The lower positioning block 632 is pressed onto the fixed chuck 51, and the position of the lining chuck is fixed and cannot be rotated; then the lateral moving cylinder 75 and the longitudinal moving cylinder 76 are both extended to move the lining chuck to the top of the shoe mouth, the upper positioning cylinder 621 is retracted, and the upper positioning rod 620 is pulled out of the upper flip positioning hole 6181, and the flip cylinder 621 is still in a retracted state, so the flip lifting plate 618 continues to rise until it rises to the highest point. At this time, the lining is straightened to facilitate glue spraying on the lining. After the glue spraying is completed, the flip cylinder 621 is extended, and the flip cylinder 621 drives the lining chuck to drop to the lowest point, pressing the lining tightly against the inside of the vamp, so that the lining is bonded to the inside of the vamp through glue, and then the air inlet 512 is exhausted, and the movable chuck 53 leaves the fixed chuck 51 under the action of the expansion spring 54, loosens the lining, and completes the flip and bonding of the lining. Finally, the flip cylinder 621 retracts and drives the lining clamp to rise to the flip position or the highest point, and then the lateral moving cylinder 75 and the longitudinal moving cylinder 76 drive the lining clamp to move to the outside of the shoe upper, and flip the lining clamp again to the initial upward state, remove the upper, install the new upper of the lining to be flipped, and lower the lining clamp to the edge of the lining to clamp the lining and continue to flip.When the lining clamp is raised to the flipping position, the upper positioning cylinder 621 extends to move and flip the lining clamp at the flipping position, thereby reducing the stroke of the flip lifting plate 618 and improving efficiency.

[0076] Embodiment 2

[0077] On the basis of the above-mentioned embodiment 1, it also includes: an upper sliding frame 622, the upper sliding frame 622 is fixed on the flip base plate 612, the upper positioning cylinder 621 is fixed on the upper sliding frame 622; and an upper linkage frame 623, one end of the upper linkage frame 623 is connected to the piston rod of the upper positioning cylinder 621, and the other end is equipped with an upper positioning rod 620.

[0078] The upper sliding frame 622 and the upper linkage frame 623 prevent the turning cylinder 621 from interfering with the upper positioning rod 620, making the structure compact.

[0079] Since the shoe opening is small, the upper sliding frame 622 and the upper linkage frame 623 can be used to change the position of the upper positioning rod 620, so that multiple turning devices can be used in combination to ensure the complete turning of the lining.

[0080] Embodiment 3

[0081] On the basis of any of the above embodiments, an elastic device 634 is further included. The elastic device 634 is fixed on the flip frame 631 and corresponds to the flip lifting plate 618, and is used to lift the flip frame 631 when resetting after flipping.

[0082] When the lining chuck is flipped to a nearly vertical state, the lining chuck is at a dead point, and the flip cylinder 621 cannot push the lining chuck to flip. However, the elastic device 634 can lift the lining chuck to rotate it to a certain angle, leaving the dead point, and the flip cylinder 621 can push the lining chuck to flip normally.

[0083] In order to facilitate the subsequent glue spraying on the lining, the lining needs to be straightened vertically, so the lining chuck needs to be rotated to an almost vertical state, and this state makes the lining chuck almost parallel to the flip lifting plate 618, thus forming a dead angle, causing the flip cylinder 621 to fail and unable to drive the lining chuck to rotate, and the elastic device 634 can provide elastic force to push the lining chuck away from the flip lifting plate 618, forming a small angle, leaving the dead point, thereby enabling the flip cylinder 621 to take effect and flip the lining chuck to the initial position.

[0084] In at least one embodiment, the elastic device 634 can be a nitrogen spring, or a spring plunger or other existing elastic device to provide an initial force for the liner chuck to rotate.

[0090] When the lining clamp is in the initial state of clamping the lining, the first flip sensor 651 faces the second detection rod 662 . When the lining clamp is completely flipped, the second flip sensor 652 faces the first detection rod 661 .

[0091] In at least one embodiment, a third flip sensor 773, a fourth flip sensor 772 and a fifth flip sensor 771 are further included, wherein the third flip sensor 773 is used to detect when the lining chuck is in the lowest position, the fourth flip sensor 772 is used to detect when the lining chuck rises to the flip position, thereby controlling the upper flip fixing device to lock the flip lifting plate 618, and the fifth flip sensor 771 is used to detect when the lining chuck rises to the highest position, that is, the third flip sensor 773, the fourth flip sensor 772 and the fifth flip sensor 771 are respectively used to detect the three working positions of the flip cylinder 621.

A flip detection rod 775 is installed on the flip lifting plate 618, and the flip detection rod 775 is used for detecting the flip sensor.

[0093] In the absence of the fourth flip sensor 772, the upper positioning cylinder 621 is in an extended state when the flip cylinder 621 is in a retracted state, and the upper positioning rod 620 is pressed on the flip lifting plate 618. When the flip lifting plate 618 rises to the upper flip positioning hole 6181 and is opposite to the upper positioning rod 620, the upper positioning rod 620 is inserted into the upper flip positioning hole 6181. There is sliding friction between the upper positioning rod 620 and the flip lifting plate 618. The roller can be added to convert the sliding friction into rolling friction, but there is pressure on the flip lifting plate 618, which is easy to affect the operation of the flip lifting plate 618. The fourth flip sensor 772 can start the upper positioning cylinder 621 when it is detected that the flip lifting plate 618 rises to the flip position, and there is no need for the upper positioning cylinder 321 to be in an extended state when the flip cylinder 621 is retracted, so that the flip lifting plate 618 can work smoothly.

[0094] The first flip sensor 651 , the second flip sensor 652 , the third flip sensor 773 , the fourth flip sensor 772 , and the fifth flip sensor 771 may all be proximity switches.
