Description

Technical Field

[0001] The present invention relates to the field of cable technology, and in particular to an automatic cable arrangement device and method for cable production. Background Art

[0002] Cables are composed of single or multiple strands of wire and an insulation layer. They need to be continuously wound during the production process for subsequent storage and transportation. In order to arrange the cables neatly on the winding drum, a cable arrangement device is required to guide and arrange the cables.

[0003] For example, the Chinese utility model patent with publication number CN213170832U discloses a fully automatic cable winding and arranging device, which includes a bottom bracket, which is fixedly connected to the ground by bolts; support side panels are provided on both sides of the bottom bracket, and the support side panels are symmetrically arranged. The support side panels are arranged in a triangular shape and are provided with a large head end and a small head end. A supporting mechanism is provided between the large head ends of the support side panels, and a cable is provided between the small head ends of the support side panels, and a support plate is provided at the bottom of the cable; the cable is provided with a rotating drive device, and the large head end is also provided with a winding mechanism and a cable arranging mechanism.

[0004] For example, the Chinese utility model patent with publication number CN217157820U discloses a cable arranging device with tension adjustment for cable manufacturing, which includes a base and a cable arranging assembly. A support plate is vertically installed on the top left side of the base, and a winding motor is provided at the front end of the support plate. A winding wheel is installed at the rear end of the winding motor, and the winding wheel is fixed to the output shaft of the winding motor. The cable arranging assembly for controlling the moving position of the cable is installed at the center top of the base. The cable arranging assembly includes a bottom plate, a spring seat, a lifting spring, a lifting block, a moving motor, a screw and a horizontal slide groove. A spring seat is installed in the center of the top of the bottom plate, and a lifting spring is provided on the top of the spring seat.

[0005] In the technical solution disclosed in the aforementioned patent, the cable traversing block, which directly contacts the cable, moves back and forth along the axis of the winding wheel to achieve multi-layer cable winding. Therefore, during the commutation of the cable traversing block, the mobile motor providing power must be stopped suddenly to quickly stop the screw, and then quickly output power to drive the screw in reverse. Frequent sudden stops can cause significant wear and tear on the motor's interior, seriously affecting its service life. Therefore, how to ensure the reciprocating movement of the cable traversing block while reducing the wear and tear on the motor caused by sudden stops is a technical problem that needs to be solved by those skilled in the art.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] This embodiment provides an automatic cable production arrangement device for guiding and arranging cables so that the cables can be tightly wound on a winding roller; during the production process, the winding roller rotates continuously so that the cables are wound on the winding roller at a constant linear speed, and the two adjacent turns of cables in each layer of cables fit together, and the two adjacent layers of cables also fit together.

[0037] Specifically, such as Figure 1 As shown, the automatic cable production arrangement device in this embodiment includes a base 1, on which a guide rail 2 with a square cross-section is horizontally fixedly installed, and the guide rail 2 is parallel to the axis of the winding roller; there are two bases 1, and the two bases 1 are respectively installed at both ends of the guide rail 2, and the bottom of the base 1 is fixedly installed on an external workbench by fasteners such as bolts, and the relative position between the base 1 and the winding roller remains unchanged; a sliding seat 3 is slidably installed on the guide rail 2, and a guide assembly 4 for guiding the cable is installed on the sliding seat 3; when working, the cable passes through the guide assembly 4, and the guide assembly 4 can clamp the cable, so that the cable between the winding roller and the guide assembly 4 is in a tensioned state; the guide assembly 4 is a prior art and will not be elaborated here.

[0038] Specifically, when the winding roller rotates to wind the cable, the sliding seat 3 drives the guide assembly 4 to move back and forth along the guide rail 2 at a constant speed. The speed of the sliding seat 3 and the guide assembly 4 matches the speed of cable winding, that is, every time the cable is wound around the winding roller, the distance the sliding seat 3 and the guide assembly 4 move is equal to the diameter of the cable. In this way, as long as the sliding seat 3 and the guide assembly 4 maintain a constant speed of translation, the cables can be evenly arranged on the winding roller, and each turn of the cable fits together.

[0039] like Figure 1 and Figure 2As shown, a motor 5 is fixedly mounted on the sliding seat 3, and the motor 5 is used to drive the first bevel gear 6 mounted on the sliding seat 3 to rotate. The first bevel gear 6 can be directly fixedly connected to the output shaft of the motor 5, or can be driven by the output shaft of the motor 5 through other transmission parts. In this embodiment, the first bevel gear 6 is fixedly mounted on the output shaft of the motor 5; a horizontal shaft 7 perpendicular to the guide rail 2 is movably mounted on the sliding seat 3. The horizontal shaft 7 can rotate and can also be translated within a certain range along its axial direction. A second bevel gear 8 and a third bevel gear 9 are fixedly mounted on the horizontal shaft 7; a first circular gear 10 and a second circular gear 9 are fixedly mounted at both ends of the horizontal shaft 7. The circular gear 11, the first rack 12 and the second rack 13 are horizontally fixedly installed on the base 1; the first circular gear 10 is always in meshing state with the first rack 12, and the width of the first rack 12 is greater than the width of the first circular gear 10; the second circular gear 11 is always in meshing state with the second rack 13, and the width of the second rack 13 is greater than the width of the second circular gear 11; when the horizontal shaft 7 rotates, it will drive the first circular gear 10 and the second circular gear 11 to rotate synchronously, and when the first circular gear 10 and the second circular gear 11 rotate, they will roll synchronously along the first rack 12 and the second rack 13, thereby driving the sliding seat 3 and the guide assembly 4 to move horizontally.

[0040] Specifically, the horizontal position of the horizontal shaft 7 along its axial direction is adjustable. As the horizontal position of the horizontal shaft 7 switches, only one of the second bevel gear 8 and the third bevel gear 9 can be in meshing state with the first bevel gear 6. There is no situation where the second bevel gear 8 and the third bevel gear 9 are meshed with the first bevel gear 6 at the same time, but there is a situation where neither the second bevel gear 8 nor the third bevel gear 9 is meshed with the first bevel gear 6; since the direction and speed of rotation of the first bevel gear 6 driven by the motor 5 are unchanged, when the bevel gear meshing with the first bevel gear 6 changes, the rotation direction of the horizontal shaft 7 will also switch, and then the rotation direction of the first circular gear 10 and the second circular gear 11 will also switch; in this way, as long as the sliding seat 3 moves to a predetermined position, the horizontal position of the horizontal shaft 7 can be automatically switched, and the sliding seat 3 can be reversed.

[0041] The automatic cable production arrangement device of this embodiment further includes an adjustment component, which is used to axially adjust the position of the horizontal axis 7; Figure 2 As shown, the adjustment assembly includes an electric slider 14 axially slidably mounted on the sliding seat 3 along the horizontal axis 7, and an adjustment ring 15 that cooperates with the horizontal axis 7 is fixedly mounted on the electric slider 14; specifically, Figure 2 illustrate, Figure 2Before the state, the second bevel gear 8 and the first bevel gear 6 are in a meshing state, the third bevel gear 9 and the first bevel gear 6 are in a separated state, and the first circular gear 10 and the second circular gear 11 rotate forward; when the sliding seat 3 and the horizontal shaft 7 move to the end of the stroke, the electric slider 14 drives the adjusting ring 15 to translate rapidly from right to left, and the adjusting ring 15 drives the horizontal shaft 7, the second bevel gear 8, the third bevel gear 9, the first circular gear 10 and the second circular gear 11 to move synchronously, the second bevel gear 8 first separates from the first bevel gear 6, and then the third bevel gear 9 and the first bevel gear 6 enter a meshing state from the separated state, the first circular gear 10 and the second circular gear 11 reverse, and the sliding seat 3 and the horizontal shaft 7 start to translate in the opposite direction.

[0042] This embodiment also provides an automatic cable arrangement method for cable production, which is completed in conjunction with the above-mentioned automatic cable arrangement device for cable production. The first bevel gear 6 is driven by the motor 5 to continuously rotate in a directional manner, and the second bevel gear 8 and the third bevel gear 9 are driven to alternately engage with the first bevel gear 6 through the axial transverse movement of the horizontal shaft 7 to achieve reversal of the sliding seat 3 and the guide assembly 4.

[0043] Example 2

[0044] like Figure 4 As shown, compared with the previous embodiment, the difference of this embodiment is that the adjustment assembly includes two wedge blocks 16 fixedly mounted on the bases 1 at both ends of the guide rail 2; when the sliding seat 3 and the horizontal shaft 7 move to a position close to the end of the stroke, the inclined surface of the wedge block 16 will contact the edge of the first circular gear 10 or the second circular gear 11, and push the first circular gear 10 or the second circular gear 11 to move axially along the horizontal shaft 7, thereby switching the axial position of the horizontal shaft 7; it should be noted that in the process of the wedge block 16 pushing the first circular gear 10 or the second circular gear 11 to move axially along the horizontal shaft 7, after the one of the second bevel gear 8 and the third bevel gear 9 that is meshed with the first bevel gear 6 is separated from the first bevel gear 6, and before the other one is meshed with the first bevel gear 6, the sliding seat 3 and the horizontal shaft 7 will rely on their own inertia to continue to translate in the initial direction until the other one is meshed with the first bevel gear 6; in this way, the automatic translation of the horizontal shaft 7 can be achieved without the need to set up an additional power source to drive the horizontal shaft 7 to translate axially.

[0045] like Figure 8As shown, two horizontal elastic rods 28 are hinged inside the sliding seat 3. The elastic rods 28 can be extended and retracted under the action of a certain external force. In the absence of external force, the elastic rods 28 will maintain a constant length. A positioning block 29 for positioning the horizontal shaft 7 is fixedly installed on the horizontal shaft 7, and the ends of the telescopic sections of the two elastic rods 28 are rotatably mounted on the positioning block 29; when the horizontal shaft 7 translates, the positioning block 29 will move synchronously, and the two elastic rods 28 will rotate under the drive of the positioning block 29, and the two elastic rods 28 will first contract and then extend to their initial length; when the two elastic rods 28 are at their initial length, they will play a positioning role on the positioning block 29, and the positioning block 29 and the horizontal shaft 7 will not easily move axially, thereby ensuring that during the normal translation of the sliding seat 3 (when not close to its stroke end), one of the second bevel gear 8 and the third bevel gear 9 can remain in meshing with the first bevel gear 6.

[0046] In this embodiment, due to the presence of the elastic rod 28, the axial translation of the horizontal shaft 7 requires a large force to achieve. The inertia of the sliding seat 3 and the horizontal shaft 7 alone is not enough to enable the wedge block 16 to push the first circular gear 10 or the second circular gear 11 to move a predetermined distance axially along the horizontal shaft 7. Based on this, Figure 4 and Figure 5As shown, in this embodiment, the adjustment component also includes an electromagnet 17 fixedly mounted on the base 1 and facing the sliding seat 3, and the sliding seat 3 is made of a material that can be attracted by a magnet; a power supply 18 is fixedly mounted on the base 1, and both poles of the power supply 18 are fixedly connected to a terminal 19, and the terminal 19 includes a hard conductor located inside and an insulating layer wrapped around the outside of the hard conductor; the electromagnet 17 is connected to the two terminals 19 by a wire; a conductive block 20 is slidably mounted on the base 1 to cooperate with one of the terminals 19, and the conductive block 20 also includes a conductive block located inside. The sliding seat 3 is fixed with a push rod 21 corresponding to the position of the conductive block 20, and the push rod 21 is made of insulating material. There are two push rods 21, and each push rod 21 corresponds to a conductive block 20; a reset unit for resetting the conductive block 20 is installed on the base 1; specifically, during the normal translation of the sliding seat 3 (when it is not close to the end of its stroke), the conductive block 20 is in contact with the corresponding terminal 19, and the power supply 18, the terminal 19, the conductive block 20 and the electromagnet 17 are in a conductive state. The source 18 supplies power to the electromagnet 17, which is magnetic. When the sliding seat 3 is translated to near the end of its stroke, the magnetism of the electromagnet 17 will attract the sliding seat 3, and the sliding seat 3 will move toward the end of the stroke under the action of the magnetic force, and the wedge block 16 will push the first circular gear 10 or the second circular gear 11 to move axially along the horizontal axis 7, and the horizontal axis 7 and the positioning block 29 will move axially along the horizontal axis 7 synchronously. During this process, the two elastic rods 28 rotate, and the two elastic rods 28 first contract and then extend, and finally the horizontal axis 7 remains in an axially stable state. ; During this process, the push rod 21 contacts the conductive block 20 and pushes the conductive block 20 to move horizontally, so that the conductive block 20 is separated from the corresponding terminal 19, and the path formed by the power supply 18, the terminal 19, the conductive block 20 and the electromagnet 17 is disconnected, the magnetism of the electromagnet 17 disappears, and the sliding seat 3 is no longer attracted by the magnetic force; the sliding seat 3 and the guide assembly 4 are able to start the reverse translation without the action of the magnetic force; after the push rod 21 is separated from the conductive block 20, the conductive block 20 is reset under the action of the reset unit, so that the electromagnet 17 is powered on again and becomes magnetic again.

[0047] This cycle repeats itself. When the second bevel gear 8 and the third bevel gear 9 are both separated from the first bevel gear 6, the sliding seat 3 continues to move to the end of its stroke through the magnetic force of the electromagnet 17 and the inertia of the sliding seat 3 itself, and one of the second bevel gear 8 and the third bevel gear 9 is engaged with the first bevel gear 6, thereby achieving stable reversal of the sliding seat 3. Due to the presence of the elastic rod 28, the second bevel gear 8 or the third bevel gear 9 will not be easily separated from the first bevel gear 6 after being engaged with the first bevel gear 6, thereby ensuring the stability of the translation of the sliding seat 3.

[0048] like Figure 6 and Figure 7As shown, the reset unit includes a guide sleeve 22 fixedly mounted on the base 1, and a piston rod 23 is horizontally slidably mounted on the guide sleeve 22, and the outer end of the piston rod 23 is fixedly connected to the conductive block 20; a reset spring 24 is connected between the piston rod 23 and the guide sleeve 22; a cavity 2301 is provided on the end surface of the piston rod 23 facing the guide sleeve 22, and an air groove 2302 is provided on the surface of the piston rod 23 to communicate with the cavity, the cross-section of the cavity 2301 is circular and a plurality of sector-shaped rubber sheets 25 are fixedly mounted in the cavity 2301; a limit ring 26 is fixedly mounted on the inner wall of the cavity 2301 on the side of the rubber sheet 25 close to the guide sleeve 22; in this embodiment, there are four rubber sheets 25, the edges of adjacent rubber sheets are in contact with each other, and the four rubber sheets 25 are in contact with the limit ring 26 in the absence of external force, and the shorter arc sides of the four rubber sheets 25 together form a smaller circular area; Figure 6 When the rubber sheet 25 is affected by the upward airflow, it will be deformed, and large gaps will be generated between the rubber sheets 25. When the rubber sheet 25 is affected by the downward airflow, it will not be deformed due to the limiting effect of the limiting ring 26.

[0049] Specifically, when the push rod 21 pushes the conductive block 20, the conductive block 20 drives the piston rod 23 to move synchronously, the piston rod 23 compresses the reset spring 24, and the air inside the guide sleeve 22 is pressed into the cavity 2301. After the push rod 21 is separated from the conductive block 20, the rebound force of the reset spring 24 causes the piston rod 23 and the conductive block 20 to reset synchronously, and the air in the cavity 2301 enters the inside of the guide sleeve 22; it should be noted that in the process of air entering the cavity 2301 from the inside of the guide sleeve 22, the rubber sheet 25 is deformed by the airflow, and the air flow area at the rubber sheet 25 is large, and the piston rod 23 can enter the guide sleeve 22 at a relatively fast speed; in the process of air flowing back from the cavity 2301 into the guide sleeve 22, the rubber sheet 25 is driven by the air flow to cling to the limit ring 26. At this time, the air flow area at the rubber sheet 25 is very small. Even if the air flow rate is accelerated, the piston rod 23 will reset at a relatively slow speed, and the corresponding conductive block 20 will also reset at a relatively slow speed; in this way, it is ensured that the conductive block 20 will be completely reset to enable the electromagnet 17 to be energized only after the sliding seat 3 is away from the end position of its stroke, thereby avoiding the situation where the magnetic force of the electromagnet 17 affects the normal translation of the sliding seat 3.

[0050] like Figure 3 As shown, a plurality of balls 27 are rotatably mounted on the sliding seat 3 and roll with the guide rail 2 . When the sliding seat 3 translates along the guide rail 2 , the balls 27 roll against the guide rail 2 to reduce the friction between the sliding seat 3 and the guide rail 2 .

[0051] Example 3

[0052] During the actual production process, with each layer of cable wound on the winding roller, the total diameter of the winding roller and the cable will increase, so the cable length of each turn of the next layer of cable will increase during the winding process. Since the linear speed of the cable is constant when the winding roller winds the cable, the time required to wind the cable one turn will increase. If the linear speed of the sliding seat 3 and the guide assembly 4 remains unchanged after reversing, then the guide assembly 4 will inevitably fail to correspond to the cable position on the winding roller. Specifically, the guide assembly 4 will start to reverse before the cable is completely wrapped around the winding roller, which will cause each turn of the cable to not fit tightly, affecting the cable arrangement effect.

[0053] Based on this, Figure 9 and Figure 10 As shown, on the basis of the previous embodiment, in this embodiment, a plurality of first speed gears 30 are fixedly installed on the output shaft of the motor 5 from top to bottom, and the diameter of the first speed gear 30 gradually decreases from top to bottom; during operation, the output shaft of the motor 5 continuously and stably rotates in a directional manner, driving each first speed gear 30 to rotate at the same angular velocity; a vertical shaft 31 is rotatably installed on the sliding seat 3, and the first bevel gear 6 is fixedly sleeved on the vertical shaft 31; a second speed gear 32 meshing with it is rotatably installed at a position corresponding to each first speed gear 30 on the vertical shaft 31; during the rotation of the first speed gear 30, the second speed gear 32 meshing with it is driven to rotate synchronously, and the angular velocities of the second speed gears 32 are different, and the second speed gear 32 with a larger diameter has a smaller angular velocity; a position corresponding to each second speed gear 32 on the vertical shaft 31 is slidably installed The first bevel gear 6 is rotated synchronously with the second speed gear 32 by pressing the first pin 33 and the second bevel gear 6 together, so that the vertical shaft 31 and the first bevel gear 6 can rotate synchronously. Figure 9To illustrate, in the initial state, the push plate 35 is at the top of its stroke and fits with the pin 33 corresponding to the top second speed gear 32, pushing the pin 33 corresponding to the second speed gear 32 into the slot 3201, and the vertical shaft 31 and the first bevel gear 6 rotate synchronously with the top second speed gear 32, and the angular velocity of the vertical shaft 31 and the first bevel gear 6 is faster; when the sliding seat 3 moves horizontally along the guide rail 2 to the end of its stroke, the push plate 35 moves downward a distance to reach the second second speed gear 32, and the second second speed gear 32 is aligned with the second second speed gear 32. The corresponding pin 33 is pushed into the slot 3201, and the vertical shaft 31 and the first bevel gear 6 rotate synchronously with the second second-speed gear 32, and the angular velocity of the vertical shaft 31 and the first bevel gear 6 slows down; and so on, as long as the sliding seat 3 moves horizontally along the guide rail 2 to the end of its stroke, the push plate 35 will move downward a distance to reach the position corresponding to the next second-speed gear 32, and the angular velocity of the vertical shaft 31 and the first bevel gear 6 will slow down, so that the speed of cable arrangement matches the speed of cable winding, ensuring that each turn of cable can fit together.

[0054] like Figure 11 and Figure 12 As shown, two vertical rods 36 extending to the top of the vertical shaft 31 are fixedly installed on the upper surface of the push plate 35, and a lifting plate 37 with a circular cross-section is fixedly installed on the top of the two vertical rods 36. The side of the lifting plate 37 is a conical surface, and an elastic member 38 is connected between the lifting plate 37 and the top surface of the vertical shaft 31; push blocks 39 for pushing the lifting plate 37 downward are fixedly installed at intervals on the base 1 on both sides of the guide rail 2, and the end faces of the push blocks 39 are inclined surfaces; a positioning rack 40 is vertically fixedly installed on the bottom surface of the lifting plate 37, and a shaft 41 is rotatably installed on the top surface of the vertical shaft 31. A ratchet 42 and a positioning gear 43 meshing with the positioning rack 40 are fixedly sleeved on the shaft 41; a pawl 44 cooperating with the ratchet 42 is rotatably installed on the top surface of the vertical shaft 31 through a torsion spring, and a blocking block 45 for blocking the pawl 44 is slidably installed on the top surface of the vertical shaft 31.

[0055] Specifically, when the sliding seat 3 moves horizontally along the guide rail 2 to the end of its stroke, the inclined surface of the push block 39 on the base 1 will contact the side of the lifting plate 37 and push the lifting plate 37 down a certain distance. When the lifting plate 37 descends, it will drive the vertical rod 36, the push plate 35 and the positioning rack 40 to descend a certain distance synchronously. The distance is exactly the distance between the two adjacent second speed-changing gears 32. The elastic member 38 is compressed to produce deformation and store energy; when the positioning rack 40 descends, it will drive the positioning gear 43, the shaft 41 and the ratchet 42 to rotate synchronously. The pawl 44 can only swing within a certain range under the obstruction of the blocking block 45, that is, the pawl 44 will limit the ratchet 42, so that the ratchet 42 cannot be reversed. Figure 11It can be seen that the ratchet 42 can only rotate counterclockwise, not clockwise; similarly, the shaft 41 and the positioning gear 43 cannot rotate clockwise, and the positioning rack 40, the vertical rod 36 and the push plate 35 will not rise under the rebound force of the elastic member 38; after the work is completed, the push plate 35 also drops to the bottom of its stroke, and then the blocking block 45 is manually removed to release the limit on the pawl 44 and the ratchet 42, and the positioning rack 40, the vertical rod 36 and the push plate 35 are able to rise and reset to their initial height under the rebound force of the elastic member 38; it should be noted that in this embodiment, the distance between the two adjacent first speed gears 30 is the same, the distance between the two adjacent second speed gears 32 is also the same, and the distance between the two adjacent staggered push blocks 39 in the vertical direction is also the same; the number of the first speed gears 30 is consistent with the number of translation strokes of the sliding seat 3, that is, the number of cable layers wound on the winding roller.

[0056] In summary, in this embodiment, the translation speed of the sliding seat 3 and the guide assembly 4 can automatically slow down during the reversing process, so that the cable arrangement speed matches the cable winding speed, ensuring that each turn of the cable can fit together.

[0057] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
