Description

Technical Field

[0001] This invention belongs to the technical field of steel wire twisting and rope making, specifically relating to a method and device for automatically adjusting the wire laying position of a wire take-up and laying machine. Background Technology

[0002] In the production equipment for the twisted strand process of steel cord, some equipment adopts an external take-up and electric winding control method. After the steel cord on the take-up reel reaches the set length and the machine stops, the end of the steel cord can stop at any position on the reel.

[0003] In existing technology, if the steel cord stops far from the required seam end, employees need to pull the steel cord out and rewind it during seaming. This increases the spacing between the steel cord strands and adds to the unloading process, potentially leading to haphazardly arranged inner coils in the finished steel cord when it reaches the tire manufacturer. During calendering in tire factories, unstable tension during steel cord release can occur, sometimes even causing the cord to break under pressure, resulting in feedback and complaints from tire companies. Therefore, a change is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a method and device for automatically adjusting the wire laying position of a take-up and laying machine, so as to solve the problem that after the steel cord on the take-up reel reaches the set length and stops, the laying device automatically stops on the side of the reel that needs to be selected, so that the employees can sew the ends nearby, reducing the waste of secondary rewinding by the unloading operator, and effectively eliminating the technical problem of loose finished steel cord laying.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] In a first aspect, the present invention provides a method for automatically adjusting the cable placement position of a cable take-up and cable laying machine, comprising:

[0007] Read the current length A1 of the steel cord wound on the take-up reel;

[0008] Read the length A2 of the current steel cord winding reel arrangement and the two-layer winding length;

[0009] The length C of the steel cord wound in two layers on the take-up reel is calculated based on A1 and A2.

[0010] The critical value F required for forced reversal of the steel cord is calculated based on data C;

[0011] The critical value F for forced reversal is compared with the remaining length B of the steel cord to determine whether the wiring device needs forced reversal.

[0012] By selecting a fixed-length parking position in advance, the control center reads the length data of the take-up reel in meters and the distance between the wire laying device and the seam face of the reel. The length data of the forced reversal is calculated. When the remaining length reaches the condition for forced reversal, the forced reversal is realized, so that the wire laying device of the take-up machine stops on the flange face side of the selected reel.

[0013] Optionally, the remaining length B of the steel cord is calculated using the following formula:

[0014] A-A1=B

[0015] In the formula, A represents the set length of the finished steel cord, and A1 represents the length of the steel cord wound by the current take-up reel.

[0016] Optionally, the data C calculated based on A1 and A2, showing that the steel cord is wound in two layers on the take-up reel, specifically includes:

[0017] Acquire the reversing proximity switch signals located on both sides of the proximity switch adjusting slide;

[0018] Pre-select the position of the fixed-length parking seam, which includes the red seam side and the green seam side;

[0019] Based on the selected fixed-length parking joint position, the length C of the steel cord wound in two layers on the take-up reel is calculated.

[0020] By setting a left proximity switch and a right proximity switch at both ends of the proximity switch adjusting slide, and using the cable guide wheel slider to receive proximity signals, the movement distance is determined to be left-right-left or right-left-right, thereby enabling the cable take-up device of the take-up machine to stop at the pre-selected position through the cable guide wheel slider.

[0021] Optionally, when the pre-selected red seam is the fixed-length parking seam position, the guide wheel slider moves and receives a signal from the left proximity switch. The control center reads the length A1 of the steel cord wound on the current take-up I-beam. When the guide wheel moves to receive a signal from the right proximity switch and reverses direction, and receives a signal from the left proximity switch again, the control center reads the length A2 of the current steel cord wound around the take-up I-beam for two layers. By subtracting A2 from A1, the length C of the steel cord traveling two layers from left to right to left on the take-up I-beam is obtained, i.e., A2 - A1 = C.

[0022] Optionally, when the preselected sewing green surface is at the fixed-length parking sewing surface position, the wire arranging guide wheel slider moves and receives the signal from the proximity switch on the right side. The control center reads the length A1 of the steel cord wound around the current take-up spool. When the wire arranging guide rail pulley travels to receive the signal from the proximity switch on the left side and changes direction to return, and then receives the signal from the proximity switch on the right side again, the control center reads the length A2 of the steel cord wound around the take-up spool in two layers from the right side → left side → right side again. By subtracting A1 from A2, the length C of the steel cord walking in two layers on the take-up spool from the right side → left side → right side is obtained, that is, A2 - A1 = C.

[0023] In the above technical solution, the two-layer metering data of left - right - left or right - left - right is obtained according to the movement of the wire arranging guide rail pulley, and the critical meter length data for forced commutation is obtained through calculation.

[0024] Optionally, the critical value F for forced commutation is compared with the remaining length B of the steel cord to determine whether the wire arranging device needs forced commutation. Specifically, it includes:

[0025] When the remaining length B of the steel cord is less than or equal to the critical value F for forced commutation, at this time, the wire arranging guide wheel performs forced commutation, and the take-up spool stops at the set length A of the finished steel cord. The wire arranging guide wheel and the steel cord stay on the flange surface on one side selected by the take-up spool.

[0026] When the remaining length B of the steel cord is greater than the critical value F for forced commutation, at this time, the wire arranging guide wheel does not need to be commutated, and the wire arranging guide wheel and the steel cord automatically stay on the flange surface on one side selected by the take-up spool.

[0027] Optionally, the critical value F for forced commutation is calculated by the following method:

[0028] When the wire arranging guide wheel slider senses that the selected fixed-length parking sewing surface is close to the proximity switch on the left side or the right side, the length C of the steel cord wound around the take-up spool in two layers calculated according to the preselected fixed-length parking sewing surface is compared with the remaining length B of the steel cord;

[0029] When B < C or B = C, the control center subtracts the distance D between the wire arranging guide wheel slider and the spool seam surface from the current remaining meter length data B to obtain the intermediate value E, and divides the intermediate value E by 2 to obtain the critical value F for forced commutation;

[0030] When B > C, there is no need to calculate the critical value F for forced commutation.

[0031] In the second aspect, the present invention also provides a device for the method of automatically adjusting the wire arranging position of a take-up wire arranging machine according to any one of the first aspects, including a take-up drive shaft and a wire arranging drive screw rod arranged parallel to the take-up drive shaft;

[0032] The cable drive screw is connected to a slidingly connected cable guide wheel slider, and the cable guide wheel slider is connected to a cable guide wheel for connecting steel cord.

[0033] The steel cord is wound onto a take-up reel that is movably connected to the drive shaft.

[0034] Optionally, the cable drive screw is provided with a proximity switch adjusting slide bar in parallel, and the proximity switch adjusting slide bar is provided with a left proximity switch and a right proximity switch, which are located at both ends of the cable guide rail slider in the plane.

[0035] Optionally, the end of the take-up drive shaft is provided with a take-up I-beam clamping cylinder for driving the rotation of the take-up I-beam.

[0036] The beneficial effects and advantages of this invention are as follows:

[0037] The method and device for automatically adjusting the winding position of a take-up and winding machine involves the control center reading the meter length data of the take-up reel and the distance between the winding device and the seam face of the reel by a pre-selected fixed-length stopping position. The meter length data for forced reversal is calculated, and when the remaining meter length reaches the condition for forced reversal, the reversal is realized, thereby making the winding device of the take-up machine stop on the flange face side of the selected reel.

[0038] Two one-way selection buttons for the sewing end face are added to the machine tool's touchscreen to ensure that the cord stops on the side selected by the customer when stopping at a fixed length, thus achieving the function of sewing the nearest end. Furthermore, the distance between the cord's stopping position and the sewing end face of the I-beam roller can be set independently. Attached Figure Description

[0041] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0042] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] Example 1:

[0045] refer to Figure 1 As shown, this embodiment provides a device for automatically adjusting the cable laying position of a cable take-up and cable laying machine, including: a take-up rotating shaft 1 and a cable laying transmission screw 2.

[0046] refer to Figure 1 As shown, in this embodiment, the take-up rotating shaft 1 and the wire-laying transmission screw 2 are arranged parallel to each other on the machine tool. The end of the take-up rotating shaft 1 is provided with a take-up I-beam clamping cylinder 4 for providing power and clamping. The take-up rotating shaft 1 is fitted with a take-up I-beam 3.

[0047] The cable guide screw 2 is slidably sleeved with a cable guide wheel slider 7, wherein the cable guide wheel slider 7 is slidably connected to a cable guide wheel 6, and a steel cord 5 is provided on the cable guide wheel 6, wherein the steel cord 5 is wound around the take-up I-beam 3 through the cable guide wheel 6;

[0048] The lead screw 2 is also equipped with a proximity switch adjusting slide 8 parallel to it. The proximity switch adjusting slide 8 is connected to a left proximity switch 9 and a right proximity switch 10. On the projection surface, the left proximity switch 9 and the right proximity switch 10 are located at the two ends of the proximity switch adjusting slide 8, respectively.

[0049] In use, the steel cord 5 is wound around the take-up I-beam spool 3 via the guide wheel 6. Upon startup, the machine tool's electrical control program is first edited. During machine startup and operation, two one-way selection buttons for the sewing end face are added to the machine tool's touchscreen to ensure that the cord stops at the side selected by the customer when stopping at a fixed length, thus achieving the function of sewing the nearest end. Furthermore, the distance between the cord's stopping position and the sewing end face of the take-up I-beam spool 3 can be set independently.

[0050] Example 2:

[0051] refer to Figure 1 As shown, this embodiment, based on Embodiment 1, further provides a method for automatically adjusting the cable laying position of a cable take-up and laying machine, including:

[0052] Read the length A1 of the steel cord 5 currently wound by the take-up reel 3;

[0053] Read the current length A2 of the steel cord wound in two layers with 5 turns of take-up I-beams and 3 rows of winding;

[0054] The length C of the steel cord 5 wrapped in two layers on the take-up reel 3 is calculated based on A1 and A2.

[0055] Based on data C, the critical value F required for the steel cord 5 to be forcibly reversed is calculated;

[0056] The critical value F for forced reversal is compared with the remaining length B of the steel cord 5 to determine whether the wiring device needs forced reversal.

[0057] Specifically, during the machine tool startup process, it first reads the length A of the finished steel cord set by the user, and then reads the length A1 of the steel cord 5 currently wound by the take-up I-beam 3 in real time. A-A1 is then used to obtain the remaining length data B of the finished steel cord that has reached the set length in meters.

[0058] During operation, the machine tool moves according to the fixed-length stopping seam position selected by the user. In this embodiment, the fixed-length stopping seam position includes the red seam and the green (blue) seam. When the user selects the red seam, the wire guide slider 7 moves along the wire transmission screw 2. When the wire guide slider 7 moves to the point where it senses the signal of the left proximity switch 9, the PLC program starts to read the length A1 of the steel cord 5 already wound on the take-up I-beam 3 at the current position. When the wire guide slider 7 moves along the other side of the wire transmission screw 2 and senses the signal of the right proximity switch 10, it reverses and returns. When the wire guide slider 7 moves to the point where it senses the signal of the left proximity switch 9 again, the PLC program reads the length A2 of the steel cord 5 already wound on the take-up I-beam 3 at the current position. Let A2-A1=C, where C is the length of the steel cord 5 wound in two layers on the take-up I-beam 3.

[0059] During operation, when the user selects to sew the green surface (blue), the data of the two-layer metering of the steel cord 5 on the take-up spool 3 moving from right - left - right can also be obtained. The principle is the same as the above-mentioned movement principle, so it will not be elaborated here.

[0060] In the above solution, the calculated length C of the steel cord 5 wound in two layers on the take-up spool 3 is compared with the remaining length B of the steel cord 5. When the remaining length B of the steel cord 5 is less than or equal to the length C of the steel cord 5 wound in two layers on the take-up spool 3, that is, B ≤ C. At this time, the PLC program subtracts the artificially set distance length (set as D) between the wire arranging device and the seam surface of the spool from the current remaining length B of the steel cord 5, that is, the intermediate value can be obtained: B - D = E, where E / 2 = F, and F is the critical meter length data for the wire arranging device to be forced to reverse. When the machine tool is running, when the remaining length B of the steel cord 5 is less than or equal to the critical meter length data F for the wire arranging device to be forced to reverse, at this time, the wire arranging guide wheel 6 is forced to reverse to correspond to the fixed-length parking position set by the user;

[0061] When the remaining length B of the steel cord 5 is greater than the length C of the steel cord 5 wound in two layers on the take-up spool 3, that is, B > C, at this time, the PLC program does not need to calculate the critical value F for forced reversal. At this time, the wire arranging guide wheel 6 can directly reach the fixed-length parking position preset by the user without forced reversal.

[0062] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the purpose of the present invention and the scope protected by the claims. These all fall within the protection scope of the present invention.
