Abstract
Description
Technical Field
[0001] The present application relates to the field of cord generation safety protection, and in particular to a rewinding anti-pinch hand isolation device. Background Art
[0002] Among the steel cord production equipment, the rewinder is mainly used for semi-finished cord welding, quality inspection of finished cord before delivery, meter calibration, etc. The rewinder has a large operating workload. Therefore, a rewinder is usually designed with two sets of winding and unwinding devices, and the rewinders are installed side by side to facilitate centralized operation by employees and improve production efficiency. However, during the production process of the rewinder, since the winding and unwinding are centralized, the operating space is relatively small, and there are certain safety risks, such as the tail of the cord hitting the arm or winding around the fingers.
[0003] Each rewinder has two sets of wire taking-up and arranging. Each set of wire taking-up has a meter wheel, a tension wheel, and a wire taking-up I-wheel, which are arranged in an up-down manner; each set of wire paying-off has a fixed wheel, a wire passing wheel, and a wire paying-off I-wheel, which are also arranged in an up-down manner, with a wire passing guide rod in the middle, and the distance between the meter wheel and the fixed wheel is generally between 30-40CM. Therefore, in the production process of the rewinder, the cords of the semi-finished I-wheels often run away and break, and the cords move arbitrarily between the guide wheels. If the employees are operating adjacent machine tools, there is a risk of being hit by the cords on the arms and faces. In addition, when the employees are straightening the cords, if the cords are reserved too long, they accidentally touch the adjacent wire taking-up and wire paying-off I-wheels, and the cords are entangled with the adjacent wire taking-up and wire paying-off I-wheels, especially when the cords in the hands of the employees are naturally coiled, if the cords in the hands are not thrown away in time, the cords will be entangled and tightened on the arms and fingers, causing production safety accidents. Summary of the invention
[0004] The purpose of the present application is to provide a rewinding anti-pinch isolation device, which is used to solve the problem in the prior art that when the cord of the semi-finished I-shaped wheel of the rewinding machine cord production process runs loose, breaks or is reserved too long, it is easy to cause harm to the operators located between adjacent machine tools, and it also affects the adjacent winding and unwinding I-shaped wheels, causing harm to the operators.
[0005] In order to solve the above technical problems, this application is implemented by adopting the following technical solutions:
[0006] On the one hand, the present application provides a rewinding anti-pinch isolation device, comprising:
[0007] Support, there are two supports, each of which includes a support A, a support B and a fixing seat, the support A is connected to the support B, the support A is connected to the fixing seat, and the support A and the support B are made of conductive material;
[0008] An isolating member is disposed between the two supports, and the isolating member is made of insulating material;
[0009] A connecting member, the connecting member is insulated and connected between the bracket A and the bracket B, and the connecting member is used to fix the isolation member between the bracket A and the bracket B, and the brackets A in different supports are located on the same side of the isolation member;
[0010] The break protection line includes a first break protection line and a second break protection line, wherein two ends of the first break protection line are electrically connected to a bracket A in different supports, and two ends of the second break protection line are electrically connected to a bracket B in different supports, and the break protection line has a connector for electrically connecting to a PLC system of a rewinding machine tool.
[0011] When in use, the device is set between the rewinding machine and the pay-off machine through the fixed seat, and the isolation barrier is formed by setting the isolation piece between the two supports. When the cord on the pay-off side runs away or breaks, the cord may fly to the rewinding side. At this time, the isolation piece will block the cord and prevent it from contacting the operator on the rewinding side, thereby protecting the operator on the rewinding side.
[0012] In addition, the present solution fixes the isolating member between bracket A and bracket B through a connector. The connector is insulated from bracket A and bracket B, and the isolating member is made of insulating material, so it does not form a conductive path between bracket A and bracket B. The first break wire is electrically connected to bracket A in different supports, and the second break wire is connected to bracket B in different supports to form two independent circuits. When in use, the connectors on the first break wire and the second break wire are respectively connected to the PLC points in the rewinding machine. When the cord on the pay-off side runs away or breaks, and the cord moves too much and touches bracket A or bracket B, the break wire connected to it will form a short circuit because bracket A and bracket B are made of conductive materials. This short circuit signal will be detected by the PLC, thereby triggering the machine tool parking mechanism to prevent further injury or damage. When the operator manually straightens the pay-off cord on the pay-off side, if the tail of the cord touches bracket A, the machine tool will also be triggered to stop to avoid the risk of the cord being entangled on the take-up spool and causing the hand to be strangled.
[0013] Optionally, the spacer is made of soft glass; soft glass is an insulating material with high transparency, so that the operator can clearly see the situation on the other side of the spacer without affecting the operating line of sight. In addition, soft glass has a certain degree of flexibility and can prevent the cord from flying out and impacting.
[0014] Optionally, the bracket A is provided with a first countersunk hole, the bracket B is provided with a second countersunk hole corresponding to the bracket A, and the connecting member is connected to the first countersunk hole and the second countersunk hole.
[0015] The connecting piece is accommodated and fixed by the first countersunk hole and the second countersunk hole corresponding to each other. The countersunk hole provides a clear installation position for the connecting piece, ensuring that the connecting piece can be accurately placed between the bracket A and the bracket B.
[0016] Optionally, the connecting member includes two first spacers disposed in the first countersunk hole and the second countersunk hole, and the two first spacers are fixed in the first countersunk hole and the second countersunk hole respectively by bolts and nuts. By using the spacers and cooperating with the bolts and nuts, a stable connection between the bracket A and the bracket B is achieved while maintaining insulation between them.
[0017] Optionally, the first spacer is made of nylon.
[0018] Optionally, the fixing base is made of a conductive material, and the bracket B is not in contact with the fixing base. The first break wire can be electrically connected to the bracket A by being connected to the base, while the bracket B is not in contact with the fixing base, thereby ensuring that the circuit formed by the first break wire and the bracket A is separated from the circuit formed by the second break wire and the bracket B, thereby reducing potential interference and short circuit risks between the circuits.
[0019] Optionally, an insulating plate is provided at the bottom of the fixing seat.
[0020] Optionally, a plurality of corresponding fixing holes are provided on the fixing seat and the insulating plate, a second spacer is provided in the fixing holes on the fixing seat, a fixing bolt is provided in the second spacer, and the fixing bolt is isolated from the fixing seat by the second spacer.
[0021] The main function of the insulating plate is to provide electrical isolation to prevent the fixing base from contacting the machine tool when it is installed on the rewinding machine tool, triggering the disconnection mechanism. A second spacer is set in the fixing hole on the fixing base to isolate the direct contact between the fixing bolt and the fixing base, thereby maintaining the insulation between the fixing base and the machine tool.
[0022] Compared with the prior art, the present application has the following beneficial effects: the present invention forms an isolation barrier by arranging an isolating member between two supports. When the cord on the pay-off side runs away or breaks, the cord may fly to the take-up side. At this time, the isolating member blocks the cord and prevents it from contacting the operator on the take-up side, thereby protecting the operator on the take-up side.
[0023] In addition, the bracket A and bracket B used to fix the isolation member in the present invention maintain a non-contact state. Among them, the first break protection line is electrically connected to the bracket A in a different support, and the second break protection line is connected to the bracket B in a different support. When in use, the first break protection line and the second break protection line are respectively connected to the PLC in the rewinding machine to form two independent protection circuits. When the cord touches the bracket A or the bracket B, the machine tool can be triggered to stop, which effectively prevents the cord from causing harm to the operator.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present disclosure / application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.
[0034] The reel is mainly used for welding semi-finished cords, quality inspection of finished cords before delivery, meter calibration, etc. The reel has a large workload. Two sets of reeling and paying-off devices are usually designed for each reel. The reel is installed side by side to facilitate centralized operation and improve production efficiency. Figure 1 Each rewinder has two sets of take-up components 5 and cable arrangement components 6. Each set of take-up components 5 has a meter wheel 51, a tension wheel 52, and a take-up I-shaped wheel 53, which are arranged in an up-down manner; each set of pay-off components 6 has a fixed wheel 61, a wire-passing wheel 62, and a pay-off I-shaped wheel 63, which are also arranged in an up-down manner, with a wire-passing guide rod in the middle. The distance between the meter wheel 51 and the fixed wheel 61 is generally between 30-40CM. Therefore, during the production process of the rewinder, the cord 7 of the semi-finished I-shaped wheel often runs away or breaks, and the cord 7 moves arbitrarily between the guide wheels. If an employee is operating an adjacent machine tool, there is a risk of being hit on the arm or face by the cord 7. In addition, when employees are straightening out the cords, if the cords are reserved too long and accidentally touch the adjacent take-up and pay-off I-shaped wheels, the cords will be entangled on the adjacent take-up and pay-off I-shaped wheels. Especially when the cords are naturally looped in the hands of employees, if they are not thrown away in time, the cords will be entangled and tightened on their arms and fingers, causing production safety accidents.
[0035] The embodiments of the present invention for solving the above problems are as follows:
[0036] Embodiment 1
[0037] This embodiment introduces a rewinding anti-pinch isolation device, referring to Figure 1 and Figure 2 The rewinding anti-pinch isolation device in this embodiment includes: two supports 1, each support 1 includes a bracket A11, a bracket B12 and a fixed seat 13. Among them, bracket A11 is connected to bracket B12, and bracket A11 is connected to the fixed seat 13, and bracket A11 and bracket B12 are made of conductive materials. An isolation member 2 is arranged between the two supports 1, and the isolation member 2 is made of insulating material. In this embodiment, the isolation member 2 is made of soft glass, which is an insulating material with high transparency, so that the operator can clearly see the situation on the other side of the isolation member 2, does not affect the operating line of sight, and has a beautiful layout. In addition, soft glass has a certain flexibility and can prevent the cord from flying out and impact.
[0038] When in use, the device is set between the rewinding machine and the pay-off machine. The two supports 1 are set vertically up and down. By setting the soft glass between the two supports 1 to form an isolation barrier, when the cord 7 on the pay-off side runs away or breaks, the cord 7 may fly to the take-up side. At this time, the soft glass will block the cord 7 and prevent it from contacting the operator on the take-up side, thereby protecting the operator on the take-up side.
[0039] Furthermore, the device further includes a connector 3, which is insulated and connected between the bracket A11 and the bracket B12. The connector 3 is used to fix the isolation member 2 between the bracket A11 and the bracket B12, and the brackets A11 in different supports 1 are located on the same side of the isolation member 2. The present embodiment also implements protection of the operator through the break protection line 4. Specifically, the break protection line 4 includes a first break protection line 41 and a second break protection line 42. The two ends of the first break protection line 41 are electrically connected to the bracket A11 in different supports 1, and the two ends of the second break protection line 42 are electrically connected to the bracket B12 in different supports 1. The break protection line 4 has a connector for electrically connecting to the PLC system of the rewinding machine.
[0040] In this embodiment, the isolating member 2 is fixed between the bracket A11 and the bracket B12 by the connecting member 3. The connecting member 3 is insulated and connected to the bracket A11 and the bracket B12, and the isolating member 2 is made of insulating material, so it will not form a conductive path between the bracket A11 and the bracket B12. The first break protection line 41 is electrically connected to the bracket A11 in different supports 1, and the second break protection line 42 is connected to the bracket B12 in different supports 1, so as to form two independent circuits. When in use, the connectors on the first break protection line 41 and the second break protection line are respectively connected to the PLC points in the rewinding machine. When the cord 7 on the pay-off side runs away or breaks, and the cord 7 moves too much and touches the bracket A11 or the bracket B12, because the bracket A11 and the bracket B12 are made of conductive materials, the break protection line 4 connected thereto will form a short circuit. This short circuit signal will be detected by the PLC, thereby triggering the machine tool parking mechanism to prevent further injury or damage. When the operator manually straightens the pay-off cord 7 on the pay-off side, if the tail of the cord 7 touches the bracket A11, the machine tool will also be triggered to stop to avoid the risk of the cord 7 being entangled on the take-up spool 53 and causing the risk of the operator's hands being tangled.

The connector 3 is accommodated and fixed by the first countersunk holes 111 and the second countersunk holes 121 corresponding to each other. The countersunk holes provide a clear installation position for the connector 3, ensuring that the connector 3 can be accurately placed between the bracket A11 and the bracket B12. Further, the connector 3 includes two first spacers 12 arranged in the first countersunk holes 111 and the second countersunk holes 121. In this embodiment, the first spacers 12 are made of nylon. The two first spacers 12 are fixed in the first countersunk holes 111 and the second countersunk holes 121 respectively by bolts 32 and nuts 33. Through the use of spacers and the cooperation of bolts 32 and nuts 33, a stable connection between the bracket A11 and the bracket B12 is achieved, while maintaining the insulation between them.

[0045] refer to Figure 6In this embodiment, the fixing base 13 is made of conductive material, the bracket A11 is welded to the fixing base 13, and the bracket B12 is not in contact with the fixing base 13. The first break protection line 41 can be electrically connected to the bracket A11 by connecting to the base, while the bracket B12 is not in contact with the fixing base 13, ensuring that the circuit formed by the first break protection line 41 and the bracket A11 is separated from the circuit formed by the second break protection line 42 and the bracket B12, reducing potential interference and short circuit risks between circuits.
