Description

Technical Field

[0001] The present invention relates to the technical field of long rope winding devices, and particularly to an automatic rope collecting device. Background Art

[0002] As a common material bundling tool, ropes are particularly needed in large quantities during the process of collecting and baling crop straws in the fields to facilitate the collection and transportation of straws. The collected crop straws are usually reserved as livestock feed. However, the crop straws collected by baling equipment need to be unbundled before they can enter subsequent production links such as chopping, crushing, granulating, and feeding. During the unbundling process, the binding ropes wound around the bales need to be collected. On the one hand, it can prevent the binding ropes from entering the straw processing and feeding links and causing harm to livestock. On the other hand, the collected binding ropes can be recycled and reused.

[0003] Existing patent one CN220549836U relates to an automatic rope coiling device, which has a frame, a transmission mechanism, a rope winding mechanism, and a rope arranging mechanism; the transmission mechanism includes a reel shaft rotatably connected to the frame and a first transmission component for driving the reel shaft to rotate; the rope winding mechanism includes a reel, the reel is rotatably connected to the reel shaft and rotates therewith; the rope arranging mechanism includes a moving module and a rope guiding component, the rope guiding component is fixed on the moving module and moves therewith, and the rope passes through the rope guiding component and is coiled on the reel. This automatic rope coiling device neatly coils the rope on the reel, improves production efficiency, and optimizes the transmission component to improve production safety. However, its structure and working principle are completely different from those of the device of the present application.

[0004] Existing patent two CN212531780U relates to a rope winding device, belonging to the technical field of long rope winding. It includes a box body, the left side surface of the box body is fixedly connected to the right side surface of a box, the left side surface of the box body is fixedly connected to the right side surface of a motor, the output shaft of the motor is fixedly connected to the bottom end of a threaded rod, and both ends of the threaded rod are respectively clamped to the upper surface and the lower surface of the inner wall of the box through two bearings. In this rope winding device, by setting the box body, a rotating shaft, and a sliding plate, the motor drives the threaded rod to drive a gear to rotate. While the gear rotates, it drives the rotating shaft to rotate. Subsequently, when the rotating shaft rotates, it drives a winding roller to rotate. Then, when the winding roller rotates, it winds up the long rope. At the same time, under the action of a spring 42, a top rod presses two movable rods through a pressure rod, so that the sliding plate tightly presses the long rope, and can maintain the tightness of the long rope winding, effectively preventing uneven winding inside, and the threaded rod can effectively perform one-way transmission to prevent the long rope from slipping. Similarly, the structure and working principle of this device are also completely different from those of the device of the present application.

The methods of collecting ropes by manual pulling or hand-cranked winches are time-consuming and laborious, with high operating costs and low working efficiency.

[0032] The following will describe the embodiments of the present invention in detail with reference to the drawings. However, the present invention can be implemented in many different ways defined and covered by the following.

[0033] Referring to Figure 1 and Figure 2 , a preferred embodiment of the present invention provides an automatic rope collecting device, comprising: a mounting bracket 6 connected to the main frame 8 of the mechanism of the material handling machine, a driving mechanism 1 and a stopping mechanism 4 connected to the mounting bracket 6, a rope winding mechanism 2 and a rope releasing mechanism 3 connected to the driving mechanism 1, and the rope winding mechanism 2 and the rope releasing mechanism 3 are arranged in sequence along a straight line. The rope winding mechanism 2 is configured to rotate after overcoming the stopping effect of the stopping mechanism 4 under the action of the driving mechanism 1, move in a first direction towards the rope releasing mechanism 3, and extend through the rope releasing mechanism 3 to wind the rope. The rope winding mechanism 2 is further configured to reversely rotate under the action of the driving mechanism 1 after the rope winding is completed, move in a second direction away from the rope releasing mechanism 3 to drive the rope wound thereon to gradually approach the rope releasing mechanism 3. The rope winding mechanism 2 is further configured to abut against the stopping mechanism 4 after rotating a set angle to stop rotating, and then continue to linearly slide and retreat in the second direction under the action of the driving mechanism 1. The rope releasing mechanism 3 is configured to rotate under the drive of the rope winding mechanism 2 during the movement of the rope winding mechanism 2 in the first direction. The rope releasing mechanism 3 is further configured to reversely rotate under the drive of the rope winding mechanism 2 during the retreat of the rope winding mechanism 2 in the second direction, stop rotating when the rope winding mechanism 2 abuts against the stopping mechanism 4, and is configured to abut against the rope wound on the rope winding mechanism 2 during the retreat process to limit the rope from continuing to retreat with the rope winding mechanism 2 to automatically drop off the rope. The stopping mechanism 4 is configured to abut against the rotating rope winding mechanism 2 to stop the rotation of the rope winding mechanism 2, so that the rope winding mechanism 2 only linearly moves in the second direction to release the rope.

[0034] When the automatic rope collecting device of the present invention is working, first, the rope winding mechanism 2 is located at the initial first position, that is, the lower end of the rope winding mechanism 2 passes through the rope releasing mechanism 3. When the driving mechanism 1 is started, the rope winding mechanism 2 rotates under the action of the driving mechanism 1, overcoming the stopping force applied by the stopping mechanism 4 thereon. At the same time, the rope winding mechanism 2 also moves in the first direction close to the rope releasing mechanism 3, so that the lower end of the rope winding mechanism 2 continues to extend after passing through the rope releasing mechanism 3, so that the rope disassembled by the rope disassembling mechanism is gradually wound around the rope winding mechanism 2 during the rotation of the rope winding mechanism 2. At the same time, driven by the rope winding mechanism 2, the rope releasing mechanism 3 rotates with the rope winding mechanism 2. When the rope winding is completed, the driving mechanism 1 is started to drive the rope winding mechanism 2 to rotate reversely. At the same time, when the rope winding mechanism 2 rotates reversely, it moves in the second direction away from the rope releasing mechanism 3. The rope winding mechanism 2 drives the rope wound thereon to retract. When the rope winding mechanism 2 rotates through a set angle, it will abut against the stopping mechanism 4 to stop rotating, and at the same time, the rope releasing mechanism 3 also stops rotating. At this time, the rope winding mechanism 2 only linearly retracts in the second direction under the action of the driving mechanism 1. During the process of the rope winding mechanism 2 driving the rope to retract and rise, the lower end of the rope winding mechanism 2 can easily get out of the rope releasing mechanism 3 and continue to linearly retract, while the rope wound around the rope winding mechanism 2 cannot pass through the rope releasing mechanism 3 and continue to retract with the rope winding mechanism 2 due to the blocking of the rope releasing mechanism 3. The rope automatically comes out of the rope winding mechanism 2 and falls downward, thus completing the entire process of rope winding and collecting.

[0035] The automatic rope collecting device of the present invention can automatically perform rope winding and rope releasing operations, avoiding rope collection by manual pulling or hand-cranked winches. It has a high degree of automation, can effectively improve work efficiency, and at the same time greatly reduce the manual operation intensity and manual operation cost. On the other hand, by driving the rope winding mechanism 2 through the stopping mechanism 4 and then driving the rope releasing mechanism 3 through the rope winding mechanism 2, it is possible to effectively avoid setting a driving mechanism to drive the rope releasing mechanism 3, saving energy, further reducing the manufacturing cost, and making the overall structure of the entire automatic rope collecting device simple and convenient to manufacture. And the stopping mechanism 4 only performs reverse rotation stopping on the rope winding mechanism 2 through a pure mechanical structure, and the stopping is stable and reliable.

[0036] Optionally, as Figure 1 shown, the driving mechanism 1 includes a driving motor 11 and a driving screw 12 connected to the output end of the driving motor 11. The driving motor 11 is fixed on the main frame body 8 of the mechanism. The driving screw 12 axially passes through the main frame body 8 of the mechanism and the mounting bracket 6. The rope winding mechanism 2 and the rope releasing mechanism 3 are arranged in sequence along the axial direction of the driving screw 12, and the rope winding mechanism 2 is rotatably installed on the outer circle of the driving screw 12, and the rope releasing mechanism 3 is fixedly installed on the outer circle of the driving screw 12. In this optional solution, the driving mechanism 1 has a simple structure and low cost, and through the structural settings of the driving mechanism 1, the rope winding mechanism 2 and the rope releasing mechanism 3, the overall structure of the device of the present invention is compact and the layout is reasonable.

[0037] Optionally, as Figure 1 shown, the rope winding mechanism 2 includes a first mounting base and a rope winding cylinder arranged circumferentially along the first mounting base. The first mounting base is sleeved on the outer circle of the driving screw rod 12 and is threadedly connected to the driving screw rod 12. The first end of the rope winding cylinder is fixedly connected to the first mounting base, and the second end of the rope winding cylinder extends axially and then slidably penetrates through the rope releasing mechanism 3.

[0038] In this alternative solution, as Figure 1 shown, the first mounting base includes a connecting sleeve 21 sleeved on the outer circle of the driving screw rod 12 and threadedly connected to the driving screw rod 12, and a first mounting plate 22 fixedly installed on the outer circle of the connecting sleeve 21. The rope winding cylinder includes a plurality of rope winding rods 23 arranged at equal intervals circumferentially along the first mounting plate 22. The first ends of the respective rope winding rods 23 are fixedly connected to the first mounting plate 22, and the second ends of the respective rope winding rods 23 extend axially and then slidably penetrate through the rope releasing mechanism 3. In this alternative solution, by arranging the connecting sleeve 21 to be threadedly connected to the driving screw rod 12, not only the processing difficulty when the whole first mounting base is threadedly connected to the driving screw rod 12 is reduced, but also the axial length of the screw connection with the driving screw rod 12 is increased through the connecting sleeve 21, thereby improving the working stability of the rope winding mechanism 2. In addition, the setting of the first mounting plate 22 meets the installation requirements of the rope winding cylinder. On the other hand, the rope winding cylinder is composed of a plurality of rope winding rods 23 arranged at equal intervals circumferentially, which meets the rope winding requirements of the rope while making the overall structure of the rope winding cylinder simple, and facilitates the easy release from the rope releasing mechanism 3 during the movement of the rope winding cylinder in the second direction.

[0039] Optionally, as Figure 1 and Figure 2 shown, the rope releasing mechanism 3 includes a second mounting base installed on the outer circle of the driving screw rod 12 and a second mounting plate 31 connected to the second mounting base. The second mounting plate 31 is rotatably arranged relative to the driving screw rod 12 under the action of the second mounting base. The second ends of the plurality of rope winding rods 23 slidably penetrate through the second mounting plate 31.

[0040] In this alternative solution, as Figure 1As shown in the figure, the second mounting base includes a connecting bearing fixedly installed on the outer circumference of the driving screw 12, and a bearing seat 32 fixedly installed on the outer circumference of the connecting bearing. In this alternative solution, the structural arrangement of the rope-off mechanism 3 not only facilitates its installation and fixation on the outer circumference of the driving screw 12 of the driving mechanism 1, but also enables it to rotate under the drive of the rewinding mechanism 2 to avoid interfering with the rotational movement of the rewinding mechanism 2. The second mounting plate 31 is fixedly installed on the outer circumference of the bearing seat 32, and a plurality of through holes penetrating the plate surface are respectively provided on the second mounting plate 31 corresponding to the plurality of rope winding rods 23. The inner diameter of the through holes is 1 mm to 3 mm larger than the outer diameter of the corresponding rope winding rod 23, so as to prevent the rope from passing through the through holes and resulting in the failure of rope-off. During operation, the bearing seat 32 rotates under the drive of the rope winding rod 23 to avoid interfering with the circumferential rotational movement of the rope winding cylinder and causing the rope winding cylinder to be unable to wind the rope normally. At the same time, through the setting of the second mounting plate 31 and the through holes thereon, the lower end of the rope winding rod 23 can easily escape from the rope-off mechanism 3 and move upward and backward. At the same time, the second mounting plate 31 blocks the rope wound on the rope winding cylinder to achieve the purpose of automatically removing the rope from the rope winding cylinder. In addition, the overall structure of the entire rope-off mechanism 3 is simple and easy to process and prepare.

[0041] Preferably, as Figure 1 shown, the automatic rope collecting device further includes a limiting sleeve 5 fixedly installed on the outer circumference of the bottom end of the driving screw 12. The limiting sleeve 5 is located outside the rope-off mechanism 3 and abuts against the rope-off mechanism 3 to prevent the rope-off mechanism 3 from sliding axially, resulting in the instability of the rope-off mechanism 3 and interfering with the escape and backward movement of the rope winding cylinder and the smooth removal of the rope.

[0042] Optionally, as Figure 1 and Figure 2 shown, the mounting bracket 6 includes a connecting cover, a connecting frame 62 and an annular retaining ring 63. The connecting cover covers the outside of the rope winding mechanism 2, and the upper end of the connecting cover is fixedly connected to the main frame body 8 of the connecting mechanism. The bottom end of the connecting cover is fixedly connected to the retaining ring 63. The retaining ring 63 is arranged around the outside of the rope-off mechanism 3. The connecting frame 62 is connected to one side of the lower end of the connecting cover. The stopping mechanism 4 is respectively arranged on the connecting frame 62 and the retaining ring 63. In this alternative solution, the overall arrangement method of the inner layer of the driving screw 12, the middle layer of the rope winding mechanism 2 and the rope-off mechanism 3, and the outer layer of the mounting bracket 6 makes the overall structure of the device of the present invention simple, the layout compact and reasonable, and at the same time avoids the interference of the rope winding mechanism 2 during operation by external disturbances.

[0043] Optionally, as Figure 2As shown, the stop mechanism 4 includes a stop rod 41 whose middle part is rotatably connected to the retaining ring 63, a connecting rod 42 fixed to the connecting frame 62, a connecting spring 43 whose two ends are respectively connected to the second end of the stop rod 41 and the connecting rod 42, and a limit block 44 fixed to the retaining ring 63. The stop rod 41 is used to abut against the first end of the rope winding drum during the rotation of the rope winding drum, and then rotate under the drive of the rope winding drum and abut against the limit block 44 to limit the further rotation of the rope winding drum. During operation, when the drive mechanism 1 drives the rope winding drum to rotate reversely, that is, rotate counterclockwise as shown in Figure 2 When the rope winding drum rotates counterclockwise, the rope winding rod 23 will abut against the first end of the stop rod 41, thereby driving the stop rod 41 to rotate. During the rotation of the stop rod 41, it will touch the limit block 44. At the same time, the stop rod 41 is also subjected to the pulling force of the connecting spring 43, so that the stop rod 41 can be tightly abutted against the limit block 44. At this time, the rope winding drum stops rotating, and at the same time, the rope releasing mechanism 3 also stops rotating, while the rope winding drum will continue to rise linearly under the action of the drive mechanism 1. The rope located below the rope releasing mechanism 3 is automatically detached from the rope winding rod 23 under the blocking action of the rope releasing mechanism 3.

[0044] In this alternative solution, as shown in Figure 1 and Figure 2 The connecting cover includes a plurality of connecting plates 61 arranged at intervals in the circumferential direction of the rope winding mechanism 2. The first ends of the plurality of connecting plates 61 are respectively fixed to the main frame body 8 of the mechanism, and the second ends of the plurality of connecting plates 61 are respectively fixedly connected to the retaining ring 63. There is a gap between the retaining ring 63 and the rope releasing mechanism 3, and the width of the gap is smaller than the outer diameter of the rope, so as to prevent the rope from passing through the gap between the retaining ring 63 and the rope releasing mechanism 3, thereby affecting the smooth release of the rope.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
