A coil guide mechanism and a coil loading method of the coil guide mechanism according to an embodiment of the present invention will be described with reference to the accompanying drawings, and it should be noted that the coil loading method according to the second aspect of the present invention is implemented by using the coil guide mechanism according to the first aspect of the present invention.

According to the first aspect of the invention, the coil stock guiding mechanism comprises a ground guiding assembly and a vehicle-mounted self-adapting assembly.

As shown in fig. 1, the ground guide assembly includes a vertical height guide plate 11 and a horizontal azimuth guide plate 12, wherein the vertical height guide plate 11 and the horizontal azimuth guide plate 12 are perpendicular to each other, and the vertical height guide plate 11 is parallel to the ground, and the horizontal azimuth guide plate 12 is perpendicular to the ground.

The vehicle-mounted self-adapting assembly comprises a base 2 and a floating disc 3, wherein the floating disc 3 is used for bearing a coil 4, the base 2 comprises a vertically arranged mounting plate 21 and a horizontally arranged bearing plate 22, the mounting plate 21 is used for connecting and mounting the floating disc 3, and the bearing plate 22 is used for providing a loadable position for the floating disc 3.

The floating disc 3 is in transmission connection with the mounting plate 21 through the first transmission assembly, and the included angle of the floating disc 3 relative to the mounting plate 21 is also adjustable, the horizontal distance of the floating disc 3 relative to the mounting plate 21 is also adjustable, and the floating disc 3 is also provided with a horizontal chute 321, and the horizontal chute 321 is used for being in sliding fit with the horizontal azimuth guide plate 12.

The bottom of the floating disc 3 is connected to the roller 73 by a second transmission assembly, the roller 73 is for sliding engagement with the vertical height guide plate 11, and the vertical distance of the roller 73 relative to the floating disc 3 is adjustable to disengage or place the floating disc 3 on the carrier plate 22.

As for the coil stock guide mechanism of the present invention, it should be noted that, firstly, the coil stock guide mechanism of the present invention has a guiding function in loading and unloading operations of the coil stock 4, for example, during loading of the coil stock 4 onto the cantilever shaft 5, the coil stock guide mechanism of the present invention can make the coil stock 4 hole of the coil stock 4 accurately correspond to the cantilever shaft 5, thereby ensuring that the coil stock 4 has no contact friction with the cantilever shaft 5 body during the process of being sleeved into the cantilever shaft 5; for another example, the coil guiding mechanism of the present invention can ensure that the coil 4 does not contact and rub against the cantilever shaft 5 body during the process of separating from the cantilever shaft 5 during the discharging process of removing the coil 4 from the cantilever shaft 5.

As shown in fig. 3 to 7, the specific working process of the coil stock guiding mechanism of the present invention for realizing the above functions is as follows:

firstly, placing and preparing a coil stock guiding mechanism: the ground guiding assembly is placed in front of the cantilever shaft 5 and kept at a suitable distance, while the vertical height guide plate 11 and the horizontal azimuth guide plate 12 in the ground guiding assembly are parallel to the cantilever shaft 5, respectively, and the central axis of the ground guiding assembly is in the same vertical plane as the central axis of the cantilever shaft 5. The coil stock 4 is placed on the float plate 3 and the on-board adaptive assembly is placed on the carrier vehicle such that the on-board adaptive assembly is aligned with the direction of the ground directing assembly.

Secondly, performing preliminary movement of the vehicle-mounted self-adaptive assembly: the control carrier vehicle moves towards the ground guiding assembly, and at the moment, the vehicle-mounted self-adaptive assembly also moves towards the ground guiding assembly, in the moving process of the vehicle-mounted self-adaptive assembly, the roller 73 arranged at the bottom of the floating disc 3 enters the ground guiding assembly, and then the roller 73 moves on the vertical height guiding plate 11, and at the moment, the vertical distance between the roller 73 and the floating disc 3 is increased so that the floating disc 3 is separated from the bearing plate 22, and therefore the floating disc 3 is in an adjustable free moving state.

Third, fine adjustment of the position of the floating disc 3 is performed: it will be appreciated that in order to ensure a precise correspondence of the aperture of the coil 4 with the cantilever shaft 5, the height and angle of the floating disc 3 are both required to be fine-tuned.

Specifically, firstly, the height of the floating disc 3 is adjusted, data such as the vertical distance between the cantilever beam and the vertical height guide plate 11, the radius of the coil stock 4, the thickness of the floating disc 3 and the like are measured, and according to a calculation formula that the vertical distance between the central axis of the cantilever beam and the upper surface of the vertical height guide plate 11 is equal to the vertical distance between the central axis of the coil stock 4 and the upper surface of the vertical height guide plate 11, the target vertical distance of the current roller 73 relative to the floating disc 3 is calculated by combining the data such as the radius of the coil stock 4 and the thickness of the floating disc 3, and the vertical distance of the roller 73 relative to the floating disc 3 is adjusted according to the target vertical distance. In this way, the adjustment of the height of the floating disc 3 is completed so that the coil 4 hole and the cantilever shaft 5 are both at the same height.

Secondly, the angle of the floating disc 3 is adjusted, at this time, the pitch angle of the ground placed by the ground guiding assembly and the cantilever shaft 5 is measured, and the included angle of the floating disc 3 relative to the mounting plate 21 is adjusted according to the pitch angle of the ground, so that the floating disc 3 is parallel to the ground, that is, the floating disc 3 is parallel to the vertical height guiding plate 11 and the cantilever shaft 5 respectively, and further, the coil 4 hole of the coil 4 placed on the floating disc 3 is parallel to the cantilever shaft 5. In this way, the adjustment of the angle of the floating disc 3 is completed so that the roll 4 hole and the cantilever shaft 5 are parallel to each other.

Fourth step, the coil stock 4 is loaded on the cantilever shaft 5: the carrier vehicle is controlled to continue to move towards the ground guide assembly and is controlled to stop moving when the cantilever shaft 5 is fully inserted into the hole of the coil stock 4. The vertical distance of the roller 73 with respect to the floating disc 3 is adjusted so that the floating disc 3 contacts and rests on the carrier plate 22.

Fifth, the carrier vehicle and the base 2 are withdrawn and the loading is completed: the transport vehicle is controlled to withdraw towards a direction away from the ground guiding assembly until the base 2 exits the ground guiding assembly, and finally the coil 4 is loaded.

In summary, according to the coil stock guiding mechanism of the invention, the first transmission assembly is arranged to enable the included angle of the floating disc 3 relative to the mounting plate 21 to be adjustable, so that the coil stock 4 holes and the cantilever shaft 5 are conveniently parallel to each other, and the second transmission assembly is arranged to enable the vertical distance of the roller 73 relative to the floating disc 3 to be adjustable, so that the coil stock 4 holes and the cantilever shaft 5 are conveniently located at the same height, thus, through the adjustment of the height and the angle of the floating disc 3, the precise correspondence of the coil stock 4 holes and the cantilever shaft 5 can be ensured by combining the horizontal guiding action of the horizontal azimuth guiding plate 12 and the vertical guiding action of the vertical elevation guiding plate 11, so that the coil stock 4 has no contact friction with the cantilever shaft 5 body in the process of sleeving the cantilever shaft 5, the abrasion of the coil stock 4 and the cantilever shaft 5 is avoided, the service life of the coil stock 4 and the cantilever shaft 5 is ensured, the automatic control adjustment is realized, the manual interference is less, and the fineness is higher.

In the related art, a coil stock is a material form which is used in a manufacturing industry in a lot, a cantilever shaft is a common material loading tool, the coil stock is a common loading and unloading operation corresponding to the cantilever shaft, and a conveying vehicle is used in the prior art to unload the coil stock to the cantilever shaft of a ground device or take the coil stock from the cantilever shaft in the opposite direction.

The coil stock relies on excircle/support or dabber/core hole when the location, often runs into the condition that the excircle has been taken up by other mechanisms, or can not atress, relies on dabber direction often again because wearing and tearing reduce the life-span of equipment and coil stock spool, even causes equipment and carrier to damage. The methods for solving the problem heretofore generally have the following: (1) rely on manual fine manipulation; (2) The mandrel is used for guiding, so that the wear resistance of the mandrel is enhanced in the design, or the mandrel is used as a wearing part to be designed, so that the mandrel is easy to replace; (3) By means of the mechanism such as fine positioning and multi-axis mechanical arm, the relative friction between the material receiving mandrel and the material shaft hole is avoided by means of an automatic control technology.

The method in the above related art generally has the following drawbacks: for the method (1), the time consumption is long, the relative position of the coil stock and the cantilever shaft is difficult to monitor manually in the operation process, the operation difficulty is high, the effect is completely dependent on the responsibility and proficiency of an operator, and abrasion cannot be avoided; for the method (2), the problem that a material carrier and a material receiving mandrel of equipment are easy to wear and damage still exists, and similarly, a guide plate is arranged and is used for guiding by using the excircle of the coiled material, but the method firstly needs a long guide mechanism, and the mechanism is easy to wear, and secondly cannot simultaneously adapt to the coiled materials with different diameters; although this method (3) can solve the problems of wear and the like, it is complicated in mechanism, high in cost and relatively long in unloading operation time; failure is not easily handled.

Therefore, in order to solve the technical defects in the related art, the invention provides a coil guiding mechanism, wherein in the process of loading and unloading the coil 4, the angle and the height of the floating disc 3 can be respectively adjusted by the first transmission assembly and the second transmission assembly, so that the height and the angle of a coil 4 hole of the coil 4 are respectively corresponding to the height and the angle of the cantilever beam, and the horizontal guiding function of the horizontal azimuth guide plate 12 and the vertical guiding function of the vertical height guide plate 11 are combined, so that the precise correspondence of the coil 4 hole and the cantilever shaft 5 is ensured, and in this way, the mechanism can ensure that the coil 4 has no contact friction with the cantilever shaft 5 body in the process of sleeving the coil 4 and the cantilever shaft 5, avoid abrasion of the coil 4 and the cantilever shaft 5, and ensure the service lives of the coil 4 and the cantilever shaft 5.

In addition, compared with the guiding method in the related art, the mechanism has the following advantages: (1) The manual interference degree is low, the automatic operation and control are realized, the operation difficulty is low, and the time consumption is short; (2) The loading and unloading operation of the coil stock 4 with different specifications can be applied, and the application range is wider; (3) The mechanism has the advantages of simple structure, lower cost, shorter loading and unloading time and higher modularization degree, and is convenient to replace and maintain when faults occur.

According to some embodiments of the present invention, the first transmission assembly may be a transmission structure such as a multi-link structure, a gear screw structure, a sliding rail and chute structure, etc., and the present invention is not limited herein, as long as the first transmission assembly can realize that the included angle and the horizontal distance of the floating disc 3 relative to the mounting plate 21 are adjustable.

In some embodiments of the present invention, as shown in fig. 1, the first transmission assembly includes a pitch angle wobble plate 61 and two links 62, an upper end of the pitch angle wobble plate 61 is hinged with the mounting plate 21, and a lower end of the pitch angle wobble plate 61 is swingably connected with the mounting plate 21 such that an angle of the pitch angle wobble plate 61 with respect to the mounting plate 21 is adjustable.

The two connecting rods 62 are parallel to each other and arranged in the vertical direction, and two ends of the two connecting rods 62 are respectively hinged with the pitch angle swinging disc 61 and the floating disc 3, so that the two connecting rods 62, the pitch angle swinging disc 61 and the floating disc 3 together form a parallel four-connecting-rod 62 structure in the vertical direction.

In this way, on the one hand, the pitch horn 61 allows for adjustment of the angle between the floating disc 3 and the mounting plate 21 of the base 2. Specifically, by controlling the lower end of the pitch angle swinging plate 61 to swing with respect to the mounting plate 21, the angle of the pitch angle swinging plate 61 with respect to the mounting plate 21 can be adjusted, and since the pitch angle swinging plate 61 is connected to the floating plate 3 by the parallel double link 62 structure, the adjustment of the angle between the floating plate 3 and the mounting plate 21, that is, the adjustment of the angle between the floating plate 3 and the base 2 can be achieved by adjusting the angle of the pitch angle swinging plate 61 with respect to the mounting plate 21.

On the other hand, the parallel four-bar linkage 62 structure constituted by the two links 62, the pitch angle wobble plate 61 and the floating plate 3 allows adjustment of the horizontal distance between the floating plate 3 and the mounting plate 21 of the base 2. Specifically, by controlling the two links 62 to be simultaneously extended, the floating disc 3 can be controlled to be horizontally moved in a direction away from the mounting plate 21, thereby increasing the horizontal distance between the floating disc 3 and the mounting plate 21 of the base 2; by controlling the simultaneous retraction of the two links 62, the floating disc 3 can be controlled to move horizontally in a direction approaching the mounting plate 21, thereby reducing the horizontal distance between the floating disc 3 and the mounting plate 21 of the base 2. From the above, the parallel four-bar linkage 62 structure described above enables adjustment of the horizontal distance between the floating disc 3 and the mounting plate 21 of the base 2.

It should be explained that, since the two links 62 are parallel to each other, and the two links 62, the pitch angle swinging plate 61, and the floating plate 3 together constitute a parallel four-link 62 structure in the vertical direction, the wall surfaces of the pitch angle swinging plate 61 and the floating plate 3 for connecting the links 62 (for example, the wall surfaces of the connecting portions 31 described later) are always kept in a mutually parallel state, and therefore the angle between the floating plate 3 and the mounting plate 21 of the base 2 is always equal to the angle between the pitch angle swinging plate 61 and the mounting plate 21, that is, the adjustment of the angle between the floating plate 3 and the mounting plate 21 of the base 2 can be achieved by adjusting the angle between the pitch angle swinging plate 61 and the mounting plate 21.

Further, the lower end of the pitch angle swinging disc 61 and the mounting plate 21 may be connected by a connecting structure such as a sliding chute sliding rod structure, a connecting rod structure or a cam shaft structure, so as to realize swinging connection between the lower end of the pitch angle swinging disc 61 and the mounting plate 21.

For example, as shown in fig. 1, the lower end of the pitch angle wobble plate 61 is hinged to the mounting plate 21 by a cam shaft 63 to achieve its swingable connection with the mounting plate 21. The cam shaft 63 is in driving connection with the motor, so that the motor can drive the cam shaft 63 to rotate, and then drive the lower end of the pitch angle swinging disc 61 to swing relative to the mounting plate 21, so as to adjust the size of an included angle between the floating disc 3 and the mounting plate 21 of the base 2.

Further, as shown in fig. 1, one ends of both links 62 are hinged to a first hinge plate 64, and the first hinge plate 64 is fixed to the pitch horn 61; the other ends of the two links 62 are hinged to a second hinge plate 65, the second hinge plate 65 is fixed to the floating plate 3, and the first hinge plate 64 and the second hinge plate 65 are parallel to each other.

Thus, the parallel link mechanism 62 mechanism formed by the first hinge plate 64, the second hinge plate 65 and the two links 62 in this embodiment maintains parallel floating in the horizontal direction and the vertical direction, so that the connection between the two links 62 and the floating disc 3 and the pitch angle swinging disc 61 respectively is facilitated, the structural stability and the connection strength of the mechanism can be improved, and the movement process of the structure is ensured to be more stable and smooth.

As shown in fig. 1, according to some embodiments of the present invention, the floating disc 3 includes a vertically disposed connection portion 31 and a horizontally disposed cargo portion 32, the connection portion 31 being drivingly connected to the mounting plate 21 by a first drive assembly, and the cargo portion 32 being connected to the roller 73 by a second drive assembly.

It will be appreciated that in the idle state in which the floating tray 3 is placed on the carrier plate 22, the bottom surface of the cargo carrying portion 32 is in contact with the upper surface of the carrier plate 22; in the operating state in which the floating disc 3 is separated from the carrier plate 22, the "adjusting the angle and horizontal distance of the floating disc 3 with respect to the mounting plate 21" mentioned in the above embodiment refers to adjusting the angle and horizontal distance of the connecting portion 31 of the floating disc 3 with respect to the mounting plate 21, and the "adjusting the vertical distance of the roller 73 with respect to the floating disc 3" mentioned in the above embodiment refers to adjusting the vertical distance of the roller 73 with respect to the cargo carrying portion 32 of the floating disc 3.

According to some embodiments of the present invention, the second transmission assembly may be a transmission structure such as a multi-link structure, a gear screw structure, a slide rail and chute structure, etc., and the present invention is not particularly limited herein, as long as the second transmission assembly can achieve the adjustable vertical distance of the floating disc 3 relative to the roller 73.

As shown in fig. 1 to 3, in some embodiments of the present invention, the second transmission assembly includes a triangle support 71 and a linear driving member 72, and the triangle support 71 has three connection ends, namely, a first connection end 711, a second connection end 712 and a third connection end 713.

The first connection end 711 is hinged to the bottom surface of the cargo part 32, and the second connection end 712 is hinged to the driving rod of the linear driving member 72; the third connecting end 713 is rotatably connected with the roller 73; and the cylinder of the linear drive 72 is hinged to the bottom surface of the cargo portion 32.

Thus, by controlling the extension and retraction of the driving rod of the linear driving member 72, the elevation of the floating disc 3 in the vertical direction can be achieved, and thus the adjustment of the vertical distance between the floating disc 3 and the roller 73 can be achieved.

Specifically, in the initial state, the line connecting the roller 73 and the cargo carrying portion 32 is perpendicular to the cargo carrying portion 32, and the vertical distance between the roller 73 and the cargo carrying portion 32 of the floating disc 3 is maximized. When the driving rod of the linear driving member 72 is extended a certain length in a direction away from the cylinder body thereof, the roller 73 moves forward, thereby driving the floating disc 3 to descend in the vertical direction, and further reducing the vertical distance between the floating disc 3 and the roller 73, after the extension operation is completed, the driving rod of the linear driving member 72 is controlled to retract to drive the roller 73 to move backward, and at this time, the retracting distance of the driving rod is equal to the extending distance of the driving rod in the extension operation, so that the roller 73 is reset to the roller 73 position in the initial state again, at this time, the connecting line of the roller 73 and the cargo carrying part 32 is again perpendicular to the cargo carrying part 32, and the vertical distance between the roller 73 and the cargo carrying part 32 of the floating disc 3 is the largest.
