Description

Technical Field

[0001] The invention relates to the technical field of composite geotextile processing equipment, and in particular to a grid rolling system and method. Background Art

[0002] In order to improve the overall strength of the geotextile, it is necessary to composite weld the staggered grid bars on its surface, and for the convenience of processing, in general, it is necessary to arrange multiple grid rolls at intervals along the width direction of the geotextile, and then unwind all the grid rolls at the same time, and at the same speed as the unwinding of the geotextile, so as to ensure that the two move synchronously and perform composite welding. The winding and unwinding of conventional grid rolls generally requires the entire winding wheel with the grid roll wound on it to be disassembled as a whole and moved to the unwinding position. First of all, in order to ensure stable rotation, the disassembly and assembly of the winding wheel is cumbersome, and due to its heavy weight, the burden on the staff during transfer is also heavy, and after being transferred to the unwinding position, it is also necessary to ensure that it can unwind and rotate normally, so a matching wheel is also required. Therefore, the transfer efficiency of the whole process is low. Summary of the invention

[0003] In order to solve the above-mentioned problem that the efficiency of transferring grille rolls is overall low and the process is relatively complicated, the present invention provides a grille rolling system and method.

[0004] The technical solution of the present invention is as follows:

[0005] A grid rolling system comprises a winding mechanism, a transfer column and an unwinding mechanism;

[0006] The winding mechanism comprises a winding main machine, on which a plurality of rotatable reference turntables are arranged, and an internal threaded shaft is arranged at the axis center of the reference turntable, a winding sleeve is connected to the outer surface of the internal threaded shaft, and a transfer turntable is arranged on the side of the winding sleeve away from the reference turntable, the planes where the reference turntable and the transfer turntable are located are parallel to each other, and the length of the winding sleeve is the same as the width of the grid bar, and a thread locker is arranged to penetrate the transfer turntable and the winding sleeve and then be detachably connected to the internal threaded shaft;

[0007] The transfer column and the winding sleeve have the same outer diameter and can be plugged into each other at a fixed angle. After plugging, the transfer column and the winding sleeve are coaxial.

[0008] The unwinding mechanism includes a movable unwinding base, and the unwinding base is provided with a plurality of unwinding racks along a straight direction, the unwinding rack includes two fork arm brackets spaced apart along the arrangement direction of the unwinding racks, and the spacing length of the fork arm brackets is the same as the width of the grille bars, the fork arm brackets include two support arms inclined upward and having an acute angle, the transfer column can be placed between the support arms and can rotate, and both ends of the transfer column do not extend beyond the unwinding rack.

[0009] Different from the existing equipment, the whole grille winding wheel is no longer moved, but transferred through a transfer column, and the transfer column can also act as a rotating shaft to assist the grille roll to rotate, which is more convenient and more efficient than the existing method.

[0010] In order to avoid affecting the transfer of the grille roll, a non-circular plug-in hole is provided on the side of the winding sleeve away from the transfer turntable, and a plug-in portion matching the plug-in hole is provided at one end of the transfer column.

[0011] The connection method between the above-mentioned winding sleeve and the grille roll is that the winding sleeve is provided with a groove in a direction perpendicular to the central axis, and both ends of the groove in the length direction pass through the winding sleeve, and the transfer column is provided with a corresponding groove at a position corresponding to the winding sleeve, and the width of the groove is the same as the thickness of the grille bar.

[0012] In order to ensure that the transfer column can rotatably support the grille roll, the length of the transfer column is greater than the width of the grille bar.

[0013] In order to adapt to the processing conditions of various composite geotextiles, the unwinding frame is connected to the unwinding base through a clamp, and the unwinding frame can be locked and fixed with the unwinding base at any position in the arrangement direction.

[0014] The specific structure of the unwinding frame is that the two fork arm brackets of a single unwinding frame are connected by a connecting seat, and the connecting seat is provided with a guide hole penetrated by the grid bar.

[0015] A grille rolling method uses the above grille rolling system and includes the following steps:

[0016] S1. Fix the winding sleeve. Sleeve the winding sleeve on the internal threaded shaft, and pass the thread locker through the transfer turntable and the winding sleeve and then fix it on the internal threaded shaft;

[0017] S2, grid bar winding, insert one end of the grid bar into the groove of the winding sleeve, and turn on the winding main machine to rotate the reference turntable until the grid bar is wound into a grid roll and then cut;

[0018] S3, transfer the grille roll, remove the thread locker, remove the winding sleeve with the grille roll wound around it, then plug the transfer column into the winding sleeve and push the grille roll to the outside of the transfer column, and ensure that both ends of the transfer column are extended relative to the grille roll;

[0019] S4, placing the grille roll, aligning the grille roll with the gap between two fork arm brackets of any vacant unwinding rack, and placing the grille roll between the two fork arm brackets, and supporting the grille roll between the support arms of the fork arm brackets by the two ends of the transfer column extension;

[0020] S5, grid roll arrangement, repeating steps S1-S4 until there are no empty unwinding racks, and adjusting the spacing between adjacent unwinding racks;

[0021] S6. Unwind the grid roll, and connect the ends of the grid bars of all grid rolls through the guide holes to the geotextile composite welding equipment.

[0022] In order to prevent the grid roll from falling apart, in step S3, after the transfer post is plugged into the winding sleeve, the central axis is in a horizontal state.

[0023] In order to facilitate the transfer of the grille roll, the transfer turntable is provided with a plurality of openings.

[0024] In order to ensure the normal rotation of the grille roll, the guide hole is located above the grille roll.

[0025] The beneficial effects of the present invention are as follows: the present invention is a grille rolling system and method, which is different from the existing equipment and transfer methods. First, the present device does not need to move the entire winding wheel, but transfers the grille roll wound on the winding sleeve by setting a transfer column. After that, the transfer column can be placed on the unwinding rack with the grille roll, and the transfer column does not need to be fixed but can be directly placed on the fork arm bracket to support the grille roll. When in use, after the end of the grille bar passes through the guide hole above, once it is pulled, it can ensure that the grille roll can be normally unwound with the center of the transfer column as a circle, and according to different operation requirements, the positions of adjacent unwinding racks can be freely changed.

[0041] Example

[0042] A grille rolling system, comprising: Figure 1 The winding mechanism, transfer column 9 and Fig. 9 , 10 The unwinding mechanism shown;

[0043] The winding mechanism includes a winding main machine 1, on which a plurality of rotatable reference turntables 2 are arranged. The reference turntables 2 can be controlled to rotate after the winding main machine 1 is powered on, thereby completing the winding of the grid bars, and the reference turntable 2 is provided with an internal threaded shaft 3 at the axis center, and the internal threaded shaft 3 does not contact the grid bars, and is used as follows. Figure 1 , 5 As shown in Figures 6 and 7, the inner threaded shaft 3 is outer-connected with a winding sleeve 4, which is directly used to wind the grid bars, and the grid roll obtained by winding is sleeved and fixed on the outer side of the winding sleeve 4. Afterwards, in order to limit the winding of the grid bars and prevent them from being out of position from the winding sleeve 4, a transfer turntable 5 is arranged on the side of the winding sleeve 4 away from the reference turntable 2. It should be noted that, as shown in Figures 6 and 7, the inner threaded shaft 3 is outer-connected with a winding sleeve 4, which is directly used to wind the grid bars, and the grid roll obtained by winding is sleeved and fixed on the outer side of the winding sleeve 4. Figure 5As shown, the planes where the reference turntable 2 and the transfer turntable 5 are located are parallel to each other and the length of the winding sleeve 4 is the same as the width of the grid bars. Therefore, during the winding process, the above-mentioned grid bars will not bend or shake, so as to ensure that the grid roll obtained by winding is in the shape of a disc, which is convenient for being placed in the unwinding mechanism and unwinding. It should be noted that in the above-mentioned structure, a threaded locker 6 is set to pass through the transfer turntable 5 and the winding sleeve 4 and is detachably connected to the internal threaded shaft 3. In this way, the threaded locker 6 can be manually disassembled and assembled to fix the winding sleeve 4 and the transfer turntable 5. For ease of use, the outer side surface of the above-mentioned threaded locker 6 can be provided with anti-slip grooves or directly set to a non-circular shape that is easy to rotate manually. In this disassembly method, the parts that need to be moved include the transfer turntable 5 and the winding sleeve 4. Therefore, it is easier than the method of disassembling the winding body as a whole, and since it does not need to be directly connected to the driving shaft, it is also more convenient and does not require disassembly of complex structures such as couplings.

[0044] Moreover, it can be seen from the above structure that the above-mentioned grille roll 8 needs to be sleeved on the outside of the winding sleeve 4 and move synchronously therewith. Therefore, in order to facilitate the rapid fixing of the end of the grille bar and perform the above-mentioned winding operation, the winding sleeve 4 is provided with a groove 41 along a direction perpendicular to the central axis, and both ends of the groove 41 in the length direction penetrate the winding sleeve 4. The design method of selecting the groove 41 to penetrate is to facilitate the transfer of the grille bar to the transfer column 9. Therefore, the transfer column 9 is provided with a corresponding groove 41 at a position corresponding to the winding sleeve 4. The width of the groove 41 is the same as the thickness of the grille bar. Under normal circumstances, before winding, it is necessary to insert the end of the grille bar into the groove 41, and then drive the winding sleeve to rotate. After rotation, the grille bar can be wound into a grille roll, and the grille roll will be fixed on the winding sleeve 4. Except along the central axis direction of the winding sleeve 4, the above-mentioned grille roll cannot move.

[0045] After winding is completed, in order to move the grid roll to the unwinding position, Figure 7 , 8 As shown, the transfer column 9 has the same outer diameter as the winding sleeve 4 and can be plugged into each other at a fixed angle. After plugging, the transfer column 9 is coaxial with the winding sleeve 4. In the initial state, Figure 7 As shown, the grid roll is then pushed toward the transfer column 9 to move as shown. Figure 8 As shown, the grille roll originally wound on the winding sleeve 4 is moved to be wound on the transfer column 9, at which time it can be moved to the position of the unwinding mechanism; and in the above structure, in order to avoid affecting the transfer of the grille roll 8, the winding sleeve 4 is provided with a non-circular plug-in hole 42 on the side away from the transfer turntable 5, and a plug-in portion matching it is provided at one end of the transfer column 9 to ensure that the plug-in direction is unique. Therefore, after the above-mentioned winding sleeve 4 and the transfer column 9 are plugged in, the grooves 411 of the above-mentioned two structures can be connected. Therefore, when moving, the above-mentioned grille roll will not be obstructed, and normal movement can be achieved.

[0046] Afterwards, which is the last step, the unwinding mechanism includes a movable unwinding base 10, and the unwinding base 10 is configured as a movable structure for easy movement, and the moving direction can be set at its bottom by universal wheels or directly placed on a mobile trolley, and then the unwinding base 10 is provided with a plurality of unwinding racks 11 along a straight line direction, and the number of unwinding racks 11 is the same as the number of grid bars of the composite geotextile that needs to be processed, and the spacing of the above-mentioned unwinding racks 11 is also the same as the above-mentioned parameters. Therefore, in order to adapt to the processing conditions of various composite geotextiles, the unwinding rack 11 is connected to the unwinding base 10 through a clamp 12, and the unwinding rack 11 can be locked and fixed with the unwinding base 10 at any position in the arrangement direction. After locking and fixing, the grid roll 8 can be placed on the corresponding unwinding rack 11 as required.

[0047] And if Fig.10 , 11 As shown, the specific structure of the unwinding rack 11 is that the unwinding rack 11 includes two fork arm brackets 111 spaced apart along the arrangement direction of the unwinding rack 11. The purpose of the fork arms 111 not being closely arranged is that the grille roll 8 needs to be placed between the two fork arm brackets 111, and the spacing length of the fork arm brackets 111 is the same as the width of the grille bar, so as to ensure that the grille roll 8 after placement will not move laterally and will not shake during the unwinding process. Afterwards, the fork arm bracket 111 includes two support arms inclined upward and having an acute angle, that is, Fig.10 In the state shown, the transfer column 9 can be placed between the support arms and can rotate, and both ends of the transfer column 9 do not extend out of the unwinding frame, thereby avoiding mutual interference between adjacent transfer columns 9, and the above-mentioned design method can ensure the normal support and rotation of the transfer column 9. Finally, it should be noted that in order to ensure that the transfer column 9 can provide rotational support for the grille roll 8, the length of the transfer column 9 is greater than the width of the grille bar, ensuring that the transfer column 9 has an extended section that can be placed at the position of the fork arm bracket 111 for support, and the outer side surface of the transfer column 9 needs to be a smooth surface, and the contact surface between the fork arm bracket 111 and the transfer column 9 also needs to be a smooth surface, thereby reducing the rotation resistance.

[0048] Finally, if Fig.11As shown, the specific structure of the unwinding rack 11 is that the two fork arm brackets 111 of a single unwinding rack 11 are connected by a connecting seat 112, and the connecting seat 112 is provided with a guide hole 113 penetrated by a grille bar, and the purpose of the guide hole 113 is to guide the grille bar so that it can rotate normally without shaking or bending, and in order to ensure the normal rotation of the grille roll 8, the guide hole 113 is located above the grille roll 8, and when unwinding, no additional downward pressure is applied to the grille roll 8, thereby ensuring that the grille roll 8 can rotate normally and unwind after being subjected to an oblique upward pulling force.

[0049] The above structure can be used to achieve that, unlike the existing equipment, the entire grille roll 8 is no longer moved on the winding wheel, but is transferred through the transfer column 9, and the transfer column 9 can also act as a rotating shaft to assist the grille roll 8 to rotate. Compared with the existing method, it is more convenient and more efficient, and the transfer column 9 does not need to be fixed to the unwinding mechanism. It only needs to ensure that the two ends of the transfer column 9 are extended relative to the grille roll 8 after the grille roll 8 is wound on its outside 3, and then it can be directly placed on the unwinding mechanism, which is very convenient and quick to disassemble and assemble.

[0050] In addition to the above structure, the present invention also discloses a grille rolling method, which uses the above grille rolling system and includes the following steps:

[0051] S1, the winding sleeve 4 is fixed; the winding sleeve 4 is sleeved on the internal threaded shaft 3, and the thread locker 6 passes through the transfer turntable 5 and the winding sleeve 4 and is fixed on the internal threaded shaft 3. In this process, the winding sleeve 4 needs to be manually sleeved and the thread locking shaft 6 needs to be twisted, which is convenient and fast, and there is no need to consider information such as the installation position;

[0052] S2, grid bar winding, insert one end of the grid bar into the groove 41 of the winding sleeve 4, and start the winding main machine 1, so that the reference turntable 2 rotates until the grid bar is wound into a grid roll 8 and then cut. It should be noted that when winding the first circle, the end of the grid bar needs to be pressed to prevent it from escaping from the groove 41;

[0053] S3, the grille roll 8 is transferred, the thread locker 6 is disassembled, the winding sleeve 4 with the grille roll 8 is disassembled, and then the transfer column 9 is plugged into the winding sleeve 4 and the grille roll 8 is pushed to the outside of the transfer column 9, and it is ensured that both ends of the transfer column 9 are extended relative to the grille roll 8; and in order to avoid the grille roll 8 from falling apart, after the transfer column 9 is plugged into the winding sleeve 4, the central axis is in a horizontal state, that is, Figure 7 In the state shown, both are in a vertical state to transfer the grille roll 8 until it reaches Figure 8In order to facilitate the transfer of the grille roll 8, the transfer turntable 5 is provided with a plurality of openings, through which the staff can push the grille roll 8 to move.

[0054] S4, the grid roll 8 is placed. After the grid roll 8 is aligned with the gap between the two fork arm brackets 111 of any vacant unwinding rack 11, it is placed between the two fork arm brackets 111, and the two ends of the transfer column 9 extend outward to support the grid roll 8 between the support arms of the fork arm brackets 111, that is, Fig. 9 and Fig.10 As shown, the installation is carried out by placing supports, so no additional fixing operation is required. By tilting the support arms, the transfer column 9 can be in close contact with the two support arms under the action of gravity. However, since the grid bars are strong but not heavy, the subsequent unwinding operation can be carried out normally under the action of external force.

[0055] S5, arranging the grid rolls 8, repeating steps S1-S4, until there are no empty unwinding racks 11, adjusting the spacing between adjacent unwinding racks 11, and after the spacing is adjusted and meets the processing requirements of the composite geotextile, the next step can be carried out;

[0056] S6, unwinding the grid roll 8, passing the grid bar ends of all grid rolls 8 through the guide holes 113 and then connecting them to the geotextile composite welding equipment.
