Examples:

Referring to fig. 1 to 11, the embodiment provides an end plate leveling device, which comprises a conveying mechanism, a leveling mechanism and a feeding mechanism 4, wherein the feeding mechanism 4 comprises a fixing component, a traversing component and a correcting component 5, the conveying mechanism is suitable for conveying a material piece 11 to an inlet of the leveling mechanism, the feeding mechanism 4 is suitable for grabbing the material piece 11 through the fixing component and continuously pushing the material piece 11 to a leveling point of the leveling mechanism through the traversing component, the correcting component 5 comprises correcting parts 16 for one-way material passing in a feeding direction, at least two correcting parts 16 are arranged at intervals, the correcting parts 16 are avoided when the material piece 11 passes in the feeding direction, so that the material piece 11 passes through, and when the material piece 11 acts on the correcting parts 16 in the direction opposite to the feeding direction, the correcting parts 16 are not avoided, so that the material piece 11 moves and leaves the leveling mechanism.

When a general rotary leveling mechanism operates, the feeding and discharging of the rotary leveling mechanism are generally carried out through two separate feeding structures and two separate discharging structures, on one hand, the separate feeding and discharging structures increase the equipment cost, and on the other hand, the fault rate is increased due to the increase of the flow. The feeding mechanism 4 in this embodiment grabs the material taking part 11 through the fixed component arranged, loads the material through the traversing component, resets the traversing component when the traversing component rotates to avoid the fixed component, prevents the fixed component from acting with the rotating mechanism, grabs the next material part 11 after the rotating is completed, and then drives the second material part 11 to load, and the correcting part 16 at the outlet side and the last material part 11 act in the process.

As shown in fig. 4, the leveling mechanism of the present embodiment preferably includes a leveling seat 6 and a leveling portion 8, where the leveling portion 8 includes a leveling roller 9, after a material piece 11 is placed on the leveling seat 6, the leveling seat 6 is lifted (may be lifted by setting a hydraulic cylinder or the like) until the material piece 11 and the leveling roller 9 stop lifting after contacting, at this time, the leveling roller 9 starts to rotate, and performs leveling, and during the process, the rotation of the material piece 11 may be reduced due to the friction between the material piece 11 and the leveling roller 9, but the material piece 11 may slightly rotate. After the turning is finished, the turning base 6 is reset, at the moment, the feeding mechanism 4 conveys the next material piece 11, and meanwhile, the correcting component 5 on the feeding mechanism 4 pushes away the previous material piece 11 for discharging.

The correction assembly 5 is shown in fig. 4, 5 and 9 to 11, and comprises a longer feeding plate 18, two correction parts 16 are arranged at the end parts and the middle part of the feeding plate 18, then an electromagnetic part 17 is arranged between the two correction parts 16, and the traversing assembly directly drives the feeding plate 18 to move.

The traversing assembly can be shown with reference to fig. 5 and 6, and comprises a fixing frame 10, the fixing frame 10 is installed at the edge of the second conveying part 3, an air cylinder is arranged in the middle of the fixing frame 10, a piston rod of the air cylinder is connected with the correcting assembly 5, and in order to ensure stability, the correcting assembly 5 is further provided with two guide rods (with reference to fig. 6), so that the whole traversing assembly 5 can be carried by the air cylinder.

The following proposes two specific schemes for correcting the unidirectional material passing of the structure.

First, the correction part 16 is rotatably arranged, and when the material 11 moves forward and acts on the correction part 16, the correction part 16 rotates to avoid. The following two preferred embodiments are further presented herein.

(1) The correction portion 16 is provided at the top with a pair of hinge shafts by which the correction portion 16 is rotatably mounted, and the hinge shafts are provided at the bottom center thereof on one side toward the feeding direction with restricting plates that restrict rotation of the correction portion 16 toward the feeding direction. In this case, as shown in fig. 9, the block on the left side of the correction portion 16, i.e., the restriction plate, is abutted against the correction portion 16 when the correction portion 16 moves in the reverse direction (i.e., when the material 11 acts in the reverse direction on the correction portion 16), and therefore the material 11 is caught and cannot pass. When the material 11 moves to the right, the correction portion 16 rotates normally, and thus can pass through. In this embodiment, reference may be made to fig. 8 to 11, fig. 9 is a state diagram when the material 11 starts to act on the first correction portion 16, fig. 10 is a schematic diagram when the material 11 continues to advance and reach between the two correction portions 16 and fig. 11 is a schematic diagram when the material 11 acts on the second correction portion 16 in a reverse direction, and at this time, the correction portion 16 is blocked by the electromagnetic portion 17 and cannot rotate, so that the material 11 cannot pass through in a reverse direction, and of course, the electromagnetic portion 17 may be replaced by a limiting plate, where the electromagnetic portion 17 may just be provided to act as a limiting plate to prevent the rotation of the correction portion 16.

It should be noted that the limiting plates and the electromagnetic portions 17 in fig. 8 to 11 are similar or identical in appearance, and in the two upper and lower schematic states in fig. 8, the lower one has at least one electromagnetic portion 17, i.e. the upper one has a total of three limiting plates and electromagnetic portions 17, and the lower one has a total of two, which is intended to indicate the relatively flexible installation position of the electromagnetic portions 17, and the electromagnetic portions 17 may also perform a limiting function in place of the limiting plates when in place.

Further, the bottom of the correction part 16 is solid, the top is hollow, the connecting line between each pair of correction parts 16 is perpendicular to the feeding direction of the conveying mechanism, the distance between each pair of correction parts 16 is larger than or equal to the width of the material piece 11, and the midpoint of the connecting line between the centers of each pair of correction parts 16 is aligned with the center of the rotary leveling mechanism. The correction part 16 is only hinged, the bottom of the correction part 16 is solid, and the top of the correction part 16 is hollow, so that the gravity center of the correction part 16 is lowered, the initial state of the correction part 16 is kept in a natural sagging state, and the problem that the correction part 16 is clamped in mid-air due to corrosion and the like is effectively reduced.

(2) The top of the correcting part 16 is installed through a one-way bearing, the correcting part 16 comprises a plurality of windmill-shaped blades, the blades rotate to avoid when the material piece 11 passes through positively, and the blades are propped against when the material piece 11 is connected reversely. This solution is not shown in the drawings, but it is easy to understand that the one-way bearing allows the blades to rotate only in one direction, so that when the material 11 moves forward, the blades can rotate and allow the material 11 to pass, and when moving backward, the blades abut against and cannot pass. However, in this solution, the spacing between the blades is such as to ensure that the material 11 passes completely, so as to prevent the material 11 from passing through half, and the second blade acts on the material 11, i.e. the solution has certain limitations.

The second type is that the correcting part 16 is installed through an elastic member, a guiding surface is arranged at the bottom of one side of the correcting part 16 facing the feeding direction, the guiding surface is acted on when the material member 11 moves forward so as to enable the correcting part 16 to translate and avoid, and the correcting part 16 is acted on by the material member 11 in the reverse direction so as to be propped against the material member 11. In this solution, a specific schematic diagram is not given, but when the material 11 moving reversely acts on the correction portion 16, the correction portion 16 is connected vertically, and the acting force of the material 11 moving reversely and the supporting force given reversely by the correction portion 16 are directly counteracted, so that the correction portion 16 will not rise, the material 11 will not pass, whereas the material 11 moves forward, and acts on the guide surface, the correction portion 16 will be acted on by an upward component force, so that the correction portion 16 can rise to pass the material 11.

As shown in fig. 1, 5 and 6, the conveying mechanism comprises a plurality of conveying parts, the conveying parts are composed of conveying rollers and driving pieces which are arranged at intervals, correction parts 12 are arranged at edges of the conveying rollers close to the rotary leveling mechanism, the correction parts 12 are arranged between two adjacent conveying rollers, the top height of each correction part 12 is larger than that of the top of each conveying roller, an adjusting structure 13 is arranged at the bottom of each correction part 12, each adjusting structure 13 comprises an adjusting groove perpendicular to the feeding direction of the conveying mechanism, and the correction parts 12 are suitable for sliding adjustment in the adjusting grooves so as to adjust the distance between the pair of correction parts 12. The adjusting structure 13 further includes an elastic member and a screwing groove, wherein the bottom of the correcting portion 16 is provided with a screwing protrusion, the screwing protrusion rotates to a locking state in a feeding direction and rotates to an opening state in a direction opposite to the feeding direction when being screwed into the screwing groove, and the screwing groove is provided with a plurality of positions at intervals at the bottom of the adjusting groove. Wherein the positioning of the screw-on protrusion and the screw-on groove can be understood in association with the screw-on fit. Since the feeding direction of the material 11 is fixed and the engagement of the screw boss and the screw groove is released to prevent the engagement from being effected in the direction of the material 11, the engagement direction of the screw boss and the screw groove is set to be rotated in the feeding direction to be locked, and rotated in the opposite direction to the feeding direction to be opened.

The setting of the correction part 12 has a limiting guide function on the material piece 11, so that the general position of the material piece 11 can be ensured to be positioned in the middle of the conveying mechanism, and the initial feeding direction of the material piece 11 is not important as long as the material piece 11 is ensured to be close to the center of the conveying mechanism as the material piece 11 rotates when the rotation leveling mechanism is selected.

As shown in fig. 1, the conveying parts include a first conveying part 1, a second conveying part 3 and a third conveying part 7, the first conveying part 1 is suitable for transferring a material piece 11 by other process equipment, the second conveying part 3 and the third conveying part 7 are respectively arranged at two sides of the rotary leveling mechanism, a feeding assembly 2 is arranged between the first conveying part 1 and the second conveying part 3, and the feeding assembly 2 comprises a feeding plate which is rotatably arranged, a rotating piece 15 for enabling the feeding plate to be rotatably arranged, an electromagnetic part 17 arranged on the feeding plate and a lifting part for driving the feeding plate. The feeding assembly 2 is a device for transferring materials from other processes to the process, when feeding is performed, the feeding plate is close to the material piece 11 through the transverse moving structure, the material piece 11 is magnetically attracted through the electromagnetic part 17, then the feeding plate is driven by the rotating part 15 to rotate 180 degrees, the feeding plate returns to the second conveying part 3 through the transverse moving structure, and then the feeding plate is reset and is ready for the next feeding.

The feeding assembly 2 is provided with an air cylinder 14, the air cylinder 14 can drive the feeding plate to transversely move between the first conveying part 1 and the second conveying part 3, and a guide rail 19 is further arranged in the moving direction of the feeding plate for guiding in order to keep stable.

On the other hand, the application provides an end plate feeding and discharging method based on the end plate rotary leveling equipment, which comprises the following steps:
