[0034] Example 1

[0035] Embodiment 1 provides a layer flipping device, which includes a fixed plate 1, a rotating component 2, a fixed frame 3, a clamping component 4, an anti-falling component 5 and a resetting component 6.

[0036] like Figure 1 and 2 As shown, the fixed plate 1 is a vertically arranged plate, preferably a high-quality structural steel plate. The rear side of the fixed plate 1 is connected to the linear module 7. The linear module 7 adopts the existing technology and is used to raise or lower the entire layer plate turning device. Of course, other lifting structures can also be used to raise or lower the entire layer plate turning device, which will not be given one by one here.

[0037] like Figure 1 and 2 As shown, the rotating assembly 2 is arranged on the front side of the fixed plate 1, and the rotating assembly 2 is used to flip the layer plate to a certain angle. Specifically, the rotating assembly 2 at least includes a motor 201, a rotating shaft 202 and a cantilever 203. Among them, the motor 201 is fixed to the fixed plate 1, the active end of the rotating shaft 202 is connected to the active shaft of the motor 201, the cantilever 203 is arranged on the shaft body of the rotating shaft 202, the cantilever 203 swings with the rotation of the rotating shaft 202, and the fixed frame 3 is connected to the cantilever 203. More specifically, the driving shaft of the motor 201 is connected to the input shaft of a reducer 204, the reducer 204 is fixed to the bearing seat 205 fixed to the fixed plate 1, the driving end of the rotating shaft 202 is fixed in the bearing of the bearing seat 205, and the driving end of the rotating shaft 202 is connected to the output shaft of the reducer 204, the driven end of the rotating shaft 202 is fixed to the seat bearing 206, the seat bearing 206 is fixed to the fixed plate 1, the motor 201 and the rotating shaft 202 are both arranged horizontally, and the remaining structures are arranged in conjunction with the motor 201 and the rotating shaft 202. Among them, the motor 201 is preferably a stepping motor or a servo motor, and the form of shaft connection is preferably a coupling connection. There are two cantilevers 203, which are respectively close to the bearing seat 205 and the seat bearing 206. The cantilever 203 includes a flip shaft fixing seat 20301, a profile buckle plate 20302 and a profile fixing plate 20303. The flip shaft fixing seat 20301 is sleeved and fixed on the rotating shaft 202. The profile buckle plate 20302 and the profile fixing plate 20303 are both fixed to the flip fixing seat. The profile buckle plate 20302 and the profile fixing plate 20303 form a rectangular structure with a fixing cavity 20304. The front end of the fixing cavity 20304 is an open structure so as to be connected to the fixing frame 3.

[0038] like Figure 1 and 3 As shown, the fixed frame 3 is arranged at the front of the rotating assembly 2, and the fixed frame 3 is used to bear the weight of the layer board. When the layer board is turned over, the layer board rotates synchronously with the fixed frame 3. Specifically, the fixed frame 3 includes 4 aluminum profile frames, and the frames are divided into two long frames 301 and two short frames 302. The two long frames 301 are arranged along the front-to-back direction, and the two short frames 302 are arranged along the left-to-right direction. The two ends of one short frame 302 are respectively fixed to the front ends of the two long frames 301, and the two ends of the other short frame 302 are respectively fixed to the rear parts of the two long frames 301. The rear ends of the two upper frames are respectively plugged and fixed in the fixing cavity 20304.

[0039] like Figure 1 and 4 As shown, there are two clamping assemblies 4, which are respectively arranged at the two short frames 302 of the fixed frame 3. The clamping assemblies 4 are used to clamp the layer plate and the fixed frame 3. The two clamping assemblies 4 arranged one in front and one behind can make the layer plate clamped higher. Specifically, the clamping assembly 4 includes a clamping mounting plate 401, a rotating cylinder 402 and a rotating arm 403. A part of the clamping mounting plate 401 is fixed to the lower side of the short frame 302. The rotating cylinder 402 adopts the existing technology and is a cylinder that can output torque and telescopic torque. The rotating cylinder 402 is arranged on the upper side of another part of the clamping mounting plate 401. The rotating arm 403 is located on the lower side of the cylinder fixed plate 1. The rotating arm 403 is "L" shaped. The active end of the rotating arm 403 is connected to the rotating cylinder 402. The rotating cylinder 402 makes the rotating arm 403 rise and fall and rotate. There are four rotating cylinders 402, one rotating cylinder 402 is arranged at each end of each clamping mounting plate 401, and there are four rotating arms 403, which match the number of rotating cylinders 402. The four rotating cylinders 402 and rotating arms 403 clamp the four corners of the layer board, and the clamping is reliable. A gasket 404 of flexible material is arranged at the clamping end of the rotating arm 403 and the position of the short frame 302 corresponding to the clamping end to avoid clamping the layer board.

[0040] like Figure 1 and 5As shown, the anti-fall component 5 is arranged at the rear part of the fixed frame 3. When the shelf is flipped, the anti-fall component 5 is used to prevent the shelf from sliding along the frame of the fixed frame 3. When flipping, the front end of the shelf is higher than the rear end, and the shelf has a tendency to slide backward along the long frame 301. The anti-fall component 5 can effectively prevent the shelf from sliding. Specifically, the anti-falling assembly 5 includes an anti-falling mounting plate 501, a guide seat 502, a wedge block 503 and a flat cylinder 504. The anti-falling mounting plate 501 is vertically fixed to the fixed frame 3. In the figure, the anti-falling mounting plate 501 is fixed on the clamping mounting plate 401, thereby indirectly fixed to the fixed frame 3. The guide seat 502 is arranged at the lower end of the anti-falling mounting plate 501. The guide seat 502 is provided with a vertical guide groove. The wedge block 503 is slidably arranged in the guide groove (not shown in the figure). The two ends of the wedge block 503 are respectively located outside the upper and lower sides of the guide seat 502. The flat cylinder 504 is arranged at the upper end of the anti-falling mounting plate 501, and the upper end of the wedge block 503 is connected to the cylinder shaft of the flat cylinder 504. More specifically, the anti-falling mounting plate 501 is fixed to the clamping mounting plate 401, and indirectly fixed to the fixed frame 3. The flat cylinder 504 is an existing cylinder with telescopic moment, which has two cylinder shafts. The axial ends of the two cylinder shafts of the flat cylinder 504 are fixed on a pull plate 505. A waist-shaped groove (not shown in the figure) is provided at the lower end of the pull plate 505, and a cylinder pull pin 506 is provided at the upper end of the wedge block 503. The cylinder pull pin 506 cooperates with the waist-shaped groove. When the cylinder shaft of the flat cylinder 504 is lifted, the pull plate 505 is driven to lift up, and the pull plate 505 drives the cylinder pull pin 506, thereby lifting the wedge block 503 and releasing the lock of the anti-fall state.

[0041] In order to keep the anti-falling assembly 5 in the locked state of the anti-falling assembly 5, in addition to the special angle design of the wedge angle at the lower end of the wedge block 503, in this embodiment, an anti-falling tension spring 507 is also designed. Specifically, an anti-falling pull pin 508 is provided on the upper end side of the wedge block 503, and an anti-falling pull pin 508 is also provided on the side of the guide seat 502. The two ends of the anti-falling tension spring 507 are respectively connected to the two anti-falling pull pins 508. When the flat cylinder 504 lifts the wedge block 503 or the wedge block 503 releases the anti-falling locking state for some reason, the wedge block 503 is extended downward under the action of the anti-falling tension spring 507, and the wedge block 503 is kept in the state of the anti-falling function.

[0042] like Figure 1 and 6As shown, the reset assembly 6 includes a reset mounting seat 601, a reset guide rod 602, a reset spring 603 and a nut 604. The reset mounting plate is fixed to the fixed frame 3. The bottom plate of the reset mounting plate is arranged horizontally. A guide hole is arranged on the bottom plate of the reset mounting plate. An expansion head 60201 is arranged at the lower end of the reset guide rod 602. The upper end of the reset guide rod 602 is screwed with the nut 604. The reset guide rod 602 can slide in the guide hole. The reset spring 603 is inserted on the reset guide rod 602, and the reset spring 603 is located between the expansion head 60201 of the reset guide rod 602 and the bottom plate of the reset mounting plate. In this embodiment, there are four reset assemblies 6, and the four reset assemblies 6 are respectively located beside the four rotating cylinders 402 or the four rotating arms 403, so as to clamp and reset the group arrangement.

[0043] After the workpiece (layer) is in place, the linear module 7 lowers the entire layer flipping device, so that the expansion head 60201 contacts the workpiece and compresses the reset spring 603 to a certain length to provide elastic force for the workpiece to reset; after it drops into place, the clamping assembly 4 is actuated, and the rotating cylinder 402 drives the rotating arm 403 to rotate 90 degrees, and then the rotating cylinder 402 lifts the rotating arm 403, so that the clamping end of the rotating arm 403 contacts and clamps the workpiece; after clamping, the flat cylinder 504 is actuated, and the cylinder shaft is pushed out, so that the wedge block 503 slides downward and contacts the workpiece under the dual action of its own gravity and the elastic force of the anti-fall tension spring 507 (the wedge angle of the wedge block 503 is selected to be suitable so that it can be self-locking), thereby completing the anti-falling; the layer flipping device moves upward a certain distance under the drive of the linear module 7 (to avoid direct flipping and interference with other components), and under the action of the motor 201, the rotating shaft 202 is rotated to the set angle to complete the flipping. When placing the workpiece, the order is reversed. The rotating component 2 moves first and rotates to the specified position; the anti-falling component 5 moves, the flat cylinder 504 moves, lifts the wedge block 503, and releases the anti-falling state; the clamping component 4 moves, the rotating cylinder 402 lowers the rotating arm 403, releases the workpiece, and then the rotating arm 403 rotates 90 degrees; at this time, the workpiece can be lowered by its own weight. In this embodiment, the resetting component 6 moves to push the workpiece into place.

[0044] Example 2

[0045] Embodiment 2 provides a layer plate turning device, which is basically the same as the layer plate turning device provided in Embodiment 1, and the difference lies in the rotating component 2.

[0046] like Figure 1 and 2As shown, the rotating assembly 2 also includes a positioning support 207, a positioning pad 208 and a positioning block 209. The positioning pad 208 and the positioning support 207 are fixed to the fixed plate 1. The positioning pad 208 is located below the cantilever 203, the positioning support 207 is located below the positioning pad 208, and the positioning block 209 is fixed to the fixed plate 1 and located above the rear side of the cantilever 203. The positioning support 207 and the positioning pad 208 are used to prevent the cantilever 203 from being too downward, that is, during the process of clamping the layer plate and turning over, the gravity of the layer plate acts on the fixed frame 3 and then transferred to the cantilever 203. If there is no positioning support 207 and the positioning pad 208, the cantilever 203 may sag and the rotating shaft 202 may be forced to reverse. The positioning block 209 is used to prevent the cantilever 203 from turning over excessively and damaging the equipment.

[0047] The rotating component 2 also includes an induction plate 210 and a sensor 211. The induction plate 210 is fixed to the driven end of the rotating shaft 202. Two sensors 211 are provided. The two sensors 211 are both fixed to the fixed plate 1. The two sensors 211 are respectively located behind and below the induction plate 210. The sensor 211 is electrically connected to the motor 201. Of course, it can also include a processor or a controller. The sensor 211 is first connected to the processor or the controller, and then connected to the motor 201. Existing mature technologies are used and will not be repeated here.

[0048] During the start-up phase of the flip, the motor 201 needs the most power. In order to reduce the load on the motor 201, the rotating assembly 2 further includes a tension spring fixing seat 212 and an assisting tension spring 213. The tension spring fixing seat 212 is vertically arranged and fixed to the upper part of the fixing plate 1. One end of the assisting tension spring 213 is hinged to the upper front side of the tension spring fixing seat 212, and the other end of the assisting tension spring 213 is hinged to the upper front side of the cantilever 203. The hinged form can be a combination of a hanging bolt 214 and a buckle 215.

[0049] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
