Description

TECHNICAL FIELD

[0001] The present application relates to the field of rope knotting devices, in particular to a rope knotter. BACKGROUND

[0002] A rope knotter is a tool for automated or semi-automated bundling of objects, widely used in logistics, agriculture, construction, fishing and medical fields. Its core function is to hold, wind and form a firm knot on a rope, wire or binding tape through mechanical structure, replacing the traditional manual knotting method to improve efficiency and safety. A typical knotter mainly consists of a clamping device, a driving mechanism, a knot-forming execution component (such as a jaw, a knotting jaw) and a cutting device. For example, a D-type knotter, as the mainstream design, clamps the rope into a hook through a flexible clamping structure, and rotates the jaw by using a worm and gear, cam mechanism, etc. to make the rope wind into a knot and then cut it off, thus realizing fast bundling.

[0003] In the prior art, the rope knotter still has the following problems:

[0004] Firstly, the clamping force and movement precision of the jaw directly affect the knot-forming quality. For example, the D-type knotter has insufficient clamping stability of the jaw to the rope when dealing with ropes of different diameters and materials, which easily causes slipping or clamping too tightly due to the difference in friction, thus reducing the success rate of knot-forming. In addition, if the rotation path and closing timing of the jaw do not match the elastic deformation of the rope accurately, it is easy to cause the knot to be loose or not to be completely closed, especially in high-speed continuous operation, the failure rate is significantly increased.

[0005] Secondly, some knotters (such as traditional square bale knotter) rely on complex mechanical linkage mechanisms (such as sector cam, multi-stage gear transmission), resulting in redundant structure, large size, and difficulty in adapting to small or portable scenarios.

[0006] Finally, some manual or semi-automatic knotters (such as simple knotter based on paper clip) require operators to have high skills to complete knotting by manually adjusting the jaw position or rope path, and their efficiency and reliability are highly dependent on the proficiency of manual operation, which is difficult to meet the stability requirements of industrial-level continuous production.

[0007] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0020] In some embodiments, the rope knotter further comprises a detection switch, at least one of the guide blocks is provided with a shaft hole in communication with the guide groove, a detection rod is slidably mounted in the shaft hole, one end of the detection rod extends into the guide groove, and the other end is directed to a trigger of the detection switch.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in further detail below in conjunction with the drawings.

[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] The existing rope knotter has a low knotting success rate, or relies on a complex mechanical linkage mechanism, and is difficult to adapt to small or portable scenarios. Manual or semi-automatic knotter (such as a simple knotter based on a paper clip) requires operators to have high skills, and has low production efficiency, and is difficult to meet the stability requirements of industrial continuous production.

[0046] To solve the above technical problems, the present embodiment provides a rope knotter. Referring to Figures 1 to 8 shown, Figure 1 is a perspective view of the rope knotter in the embodiment of the present application, Figure 2 is a perspective view of the rope knotter in the embodiment of the present application after removing part of the frame, Figure 3 is a front view of the rope knotter in the embodiment of the present application,Figure 4 is a side view of the rope knotter in the embodiment of the present application, Figure 5 is Figure 4 is a sectional view of the A section in Figure 6 is a top view of the rope knotter in the embodiment of the present application, Figure 7 is a perspective view of the molding die in the embodiment of the present application, Figure 8 is a schematic view of the rope knotting in the molding die in the embodiment of the present application.

[0047] A rope knotter comprises a molding mechanism 1, a rope feeding mechanism 2, a rope pulling mechanism 3 and a rope pushing mechanism 4.

[0048] As shown in Figure 2 , the molding mechanism 1 comprises two openable molding dies 10 and a molding driving mechanism 13 configured to drive the two molding dies 10 to open and close, and the two molding dies 10 are each provided with a groove 100 on the opening and closing surface, and the grooves 100 of the two molding dies 10 jointly form a track groove 14 for the rope to move when closed, as shown in Figure 7 , the track groove 14 is shaped to match the shape of a single knot, and the edges of the two molding dies 10 are respectively provided with an inlet 141 and an outlet 142, the rope enters the track groove 14 from the inlet 141 and then extends out of the outlet 142.

[0049] In some embodiments of the molding die 10, as shown in Figure 7 and Figure 8 , the two molding dies 10 are respectively a lower molding die 11 and an upper molding die 12; the track groove 14 comprises a ring groove 143, a connecting groove 144 and a rope passing groove 145 connected in sequence; the lower molding die 11 is provided with the inlet 141 and the ring groove 143 and the rope passing groove 145 of the track groove 14, and the upper molding die 12 is provided with the outlet 142 and the connecting groove 144 of the track groove 14; the ring groove 143 is formed by extending inward from the opening, the front end of the connecting groove 144 is connected with the end of the ring groove 143, and the end of the connecting groove 144 is connected with the front end of the rope passing groove 145; the front end of the rope passing groove 145 is located at the periphery of the ring groove 143, the middle part is connected with the side of the rope passing groove 145 away from the upper molding die 12, and the end is located inside the ring groove 143 and communicates with the outlet 142 of the track groove 14. The rope first enters the ring groove 143 from the opening, then forms a rope loop in the ring groove 143, then enters the upper end of the rope loop through the connecting groove 144, then passes through the rope loop from outside to inside and from bottom to top through the rope passing groove 145, and finally the rope end extends out of the outlet 142 to form a single knot structure.

[0050] It can be understood that the two molding dies 10 can also be a pair of dies arranged oppositely left and right, or other directions can be arranged as needed.

[0051] To prevent the rope end from mistakenly entering the rope-threading groove 145 when passing through the area where the annular groove 143 meets the rope-threading groove 145, refer to... Figure 7 and Figure 8 As shown, the annular groove 143 includes a straight segment 146 extending in a straight line from the opening, and the middle part of the rope-passing groove 145 is connected to the straight segment 146. With this configuration, the rope, guided by the straight segment 146, can pass through the rope-passing groove 145 in a straight direction, greatly improving the accuracy of the rope moving along the annular groove 143.

[0052] In one embodiment of the molding drive mechanism 13, see [reference] Figure 7 and Figure 8 As shown, the molding drive mechanism 13 includes a first gripper cylinder fixedly mounted on the frame 5, and two molding dies 10 are respectively fixed on the two grippers of the first gripper cylinder. The two molding dies 10 are driven to close by the first gripper cylinder.

[0053] In other embodiments of the molding drive mechanism 13 (not shown), the molding drive mechanism 13 may also be an existing ordinary cylinder or linear motor, which is fixed on the frame 5 and drives one of the molding molds 11 to move, while the other molding mold 12 is fixed on the frame 5, and the opening and closing function is achieved by the movement of a single molding mold 11.

[0054] The rope feeding mechanism 2 is located at the front end of the forming mold 11 and is configured to feed the rope into the inlet 141 of the track groove 14.

[0055] In some embodiments of the rope feeding mechanism 2, see [reference]. Figure 3 and Figure 4As shown, the rope feeding mechanism 2 comprises a motor 21, an opening and closing driving mechanism 22, a roller 23, a guide block 24 and a universal shaft transmission mechanism 25. The roller 23, the guide block 24 and the universal shaft transmission mechanism 25 are provided in two groups. The roller 23 is rotatably installed on the guide block 24 in the same group and connected with the universal shaft transmission mechanism 25 in the same group. The guide block 24 is provided with a guide groove 241 at the front end and the rear end of the roller 23 in the same group. The two groups of rollers 23 and the guide blocks 24 are oppositely arranged. The motor 21 is in driving connection with the universal shaft transmission mechanism 25, such as through gear transmission. The opening and closing driving mechanism 22 is connected with the guide block 24 and configured to drive the two guide blocks 24 to move relative to each other. When the two guide blocks 24 move relative to each other to adhere to each other, the guide grooves 241 of the two guide blocks 24 are closed to form a guide hole 242, and the guide hole 242 faces the space between the two rollers 23. When the rope feeding mechanism 2 works, the rope first enters between the rollers 23 from the guide hole 242 at the front end of the roller 23, and then is fed to the rear end from the guide hole 242 at the rear end of the roller 23. The space between the rollers 23 and the space between the guide blocks 24 can be driven to open by the opening and closing driving mechanism 22, so as to facilitate the putting-in and taking-out of the rope. The universal shaft transmission mechanism 25 can use the existing universal shaft transmission mechanism. Since the universal shaft transmission mechanism has a certain activity, it can ensure the smooth operation of the opening of the roller 23 and the guide block 24.

[0056] The embodiment that the opening and closing driving mechanism 22 drives the guide block 24 to open and close can be the same as the above-mentioned embodiment that the forming driving mechanism 13 drives the two forming molds 10 to open and close, which will not be described herein again.

[0057] Further, referring to Figure 2 and Figure 5 As shown, in order to detect whether the rope enters the guide block 24, the rope knotter further comprises a detection switch 26. At least one guide block 24 at the front end of the roller 23 is provided with a shaft hole 243 in communication with the guide groove 241 thereof, and a detection rod 244 is slidably installed in the shaft hole 243. In the initial state, one end of the detection rod 244 extends into the guide groove 241, and the other end is arranged towards the trigger of the detection switch 26. When the rope passes through the guide hole 242, the detection rod 244 is pushed to move along the shaft hole 243, thereby triggering the detection switch 26. The detection switch 26 feeds back an electric signal to the control device, and the control device determines that the rope passes through the guide block 24 at this time, and can further control the motor 21 to drive the roller 23 to rotate and the automatic operation of other mechanisms at the rear end.

[0058] In order to improve the conveying capacity of the roller 23 to the rope and avoid the deflection of the rope between the rollers 23, referring to Figure 5As shown, in some embodiments of the roller 23, the wheel surface of the roller 23 is provided with a rope groove 231 adapted to the rope, and when the two rollers 23 are closed, the rope grooves 231 combine to form a limiting channel for the rope, and the rope moves in the limiting channel under the driving of the friction force inside the rope groove 231, avoiding disengagement to the sides of the roller 23.

[0059] It can be understood that the above-mentioned rope feeding mechanism 2 can also be an existing conveying mechanism capable of conveying the rope in a predetermined straight line direction.

[0060] The rope pulling mechanism 3 is arranged at the rear end of the forming mold 12 and is configured to pull the rope head extending out of the outlet 142 of the track groove 14.

[0061] In addition to using existing mechanisms with rope pulling function, the rope pulling mechanism 3 can also use the following embodiments: refer to Figure 2 and Figure 3 As shown, the rope pulling mechanism 3 includes a second jaw cylinder 31 and a linear motion mechanism (not shown), the second jaw cylinder 31 is arranged towards the outlet 142 of the track groove 14 and is configured to clamp the rope head, and the linear motion mechanism (not shown) is connected with the second jaw cylinder 31 and is configured to drive the second jaw cylinder 31 to move away from the outlet 142. The linear motion mechanism (not shown) can be fixedly installed on the rack 5 and selected from existing linear cylinders, linear motors and other linear driving mechanisms. When the rope pulling mechanism 3 works, the second jaw cylinder 31 clamps the rope head, then pulls the rope head to the rear end under the driving of the linear motion mechanism (not shown), and finally resets to the initial state for the next rope pulling operation.

[0062] It can be understood that the power for moving the rope in the track groove 14 can be provided by the roller 23 of the rope feeding mechanism 2, but in some cases it cannot move forward efficiently, for example, the outer surface of the rope is relatively rough, causing the friction between the rope and the inside of the track groove 14 to be relatively large, and the rope is difficult to move quickly and effectively in the track groove 14, or the rope is relatively soft and easy to bend at the opening front end. In order to solve this problem, refer to Figure 3 and Figure 6As shown, the rope knotter further comprises a rope pushing mechanism 4 arranged between the rope feeding mechanism 2 and the forming mechanism 1, and the rope pushing mechanism 4 is used to push the rope at the front end of the forming die 11 into the entrance in sections. Specifically, the rope pushing mechanism 4 comprises a clamping driving mechanism 41, a rope pushing driving mechanism 42, and two clamping members 43 which can be opened and closed; the clamping members 43 are provided with a positioning groove 431 for positioning the rope, the clamping driving mechanism 41 is connected with the clamping members 43 and is configured to drive the clamping members 43 to open and close, so as to realize the operation of clamping the rope; the rope pushing driving mechanism 42 is connected with the clamping driving mechanism 41 and is configured to drive the clamping driving mechanism 41 and the clamping members 43 to move towards the opening direction, so as to realize the operation of pushing the rope. When the rope pushing mechanism 4 works, the clamping members 43 clamp the rope between the rope feeding mechanism 2 and the forming mechanism 1 under the drive of the clamping driving mechanism 41, then move towards the rear end under the drive of the rope pushing driving mechanism 42, so as to push the rope into the entrance, and finally reset to prepare for the next pushing operation. In this way, the rope can be transported into the track groove 14 in sections, so as to ensure the moving speed of the rope and the knotting efficiency.

[0063] The clamping driving mechanism 41 can be an existing electric clamping jaw or clamping jaw cylinder, and the rope pushing driving mechanism 42 can be an existing linear driving mechanism such as a cylinder or an electric push rod, which will not be described here.

[0064] When the rope knotter of the present application works, the two forming dies 10 are closed, and the recess 100 forms the track groove 14 for the rope to move. It should be noted that the rope is selected to have a certain hardness and be able to move in the track groove 14, for example, a plastic rope. First, the rope feeding mechanism 2 feeds the rope into the entrance 141 of the track groove 14; then the rope moves along the track groove 14, and since the shape of the track groove 14 is adapted to the shape of the single knot, the rope automatically forms a single knot during the movement along the track groove 14, and the rope head extends out of the outlet; finally, the forming driving mechanism 13 drives the forming die 10 to open, and the rope pulling mechanism 3 tightens the extended rope head, so as to complete the knotting operation. Compared with the traditional rope knotter such as the clamping jaw knotter, the square bale knotter, and the semi-automatic knotter, the rope knotter of the present application forms a single knot structure by moving the rope along the track groove 14, and the knotting operation of the rope can be completed without relying on manual operation, so as to have a higher knotting efficiency, and the process of forming a single knot does not need to be controlled by using an active execution component such as a clamping jaw, so as to reliably form a single knot and improve the success rate of the rope knotting.

[0065] The above description is only an optional embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
