detailed description

In view of the problems of the prior art, the present invention proposes a new yarn guide.

First embodiment

1 and 2, the yarn guide of the present embodiment includes: a base 1, a linear guide 2 extending along a straight line on the base 1, and a slide 3 on the linear guide 2. The linear guide 2 has two ends, respectively For the first end I and the second end II, the slider 3 is movable along the linear guide 2 between the first end I and the second end II.

A conveyor belt 4 is disposed on both sides of the linear guide 2, and the conveyor belt 4 surrounds the linear guide 2 and is spaced apart from the linear guide 2. The portion of the conveyor belt 4 that is transported along the straight line is opposite and parallel with the linear guide 2, and the conveyor belt 4 on both sides of the linear guide 2 The conveying direction is reversed, and the side faces of the slider 3 on both sides in the extending direction of the linear guide 2 are opposed to the conveying belt 4.

A first electromagnet 5 and a second electromagnet 6 are respectively disposed on two sides of the linear guide 2, and the first electromagnet 5 and the second electromagnet 6 are disposed opposite to each other, and between the first electromagnet 5 and the linear guide 2, The portion between the second electromagnet 6 and the linear guide 2 is conveyed in a straight line by the conveyor belt 4, respectively. The slider 3 is provided with a soft magnetic material, and the slider 3 of the present embodiment is provided with a soft magnetic material on the side surfaces on both sides in the extending direction of the linear guide 2.

The working principle of the yarn guide is:

When the slider 3 is placed at the first end I of the linear guide 2, the first electromagnet 5 is energized to be magnetized, and the suction slider 3 is moved toward the side of the first electromagnet 5 until the slider 3 and the first electromagnet 5 are moved. One side of the conveyor belt is joined;

Thereafter, the first electromagnet 5 is kept energized, and the slider 3 is moved along the linear guide 2 to the second end II of the linear guide 2 at a constant speed along the linear guide 2;

When the slider 3 is moved to the second end II of the linear guide 2, the first electromagnet 5 is deenergized and the second electromagnet 6 is energized, and the slider 3 is separated from the conveyor on the side of the first electromagnet 5, and The second electromagnet 6 is attracted to the conveyor belt on the side of the second electromagnet 6 until it is engaged with the conveyor belt on the side of the second electromagnet 6;

Since the conveying directions of the conveyor belts 4 on both sides of the linear guide 2 are opposite, after that, the second electromagnet 6 is kept energized, the moving direction of the slider 3 is reversed, and the conveyor belt 4 is uniformly oriented along the linear guide 2 toward the first end I of the linear guide 2 mobile. By repeating the above steps, the slider 3 is reciprocally moved laterally on the linear guide 2, and in the process, the yarn passes through the slider and is wound around the winding bobbin.

Compared with the prior art, the yarn guide of the present technical solution can better realize the winding of the yarn, and has a simple structure. More importantly, when the slider 3 is separated from the conveyor belt on one side at both ends of the linear guide 2 and engaged with the reversely conveyed conveyor belt on the other side, the reversely conveyed conveyor belt is being reversely conveyed at a certain speed, the slider 3 can obtain a large reverse speed immediately, and the sliding member 3 is immediately reversed at both ends of the linear guide 2, and the yarn does not form a dense winding at both ends of the winding bobbin, which can improve the winding quality of the yarn.

In the implementation, the control center of the yarn winding device can program the first electromagnet 5 and the second electromagnet 6 to be alternately energized and de-energized at both ends of the linear guide 2, so that the sliding member 3 is completed at both ends of the linear guide 2. The direction of movement is reversed.

Referring to Figures 1 and 2, the slider 3 and the linear guide 2 have a gap in a direction perpendicular to the direction in which the linear guide 2 extends. When the first electromagnet 5 or the second electromagnet 6 is energized, the sliding member 3 can be perpendicular to the electromagnetic force. The linear guide 2 is slightly traversed in the extending direction to engage the conveyor belt.

The linear guide 2 is fixed to the base 1, and the first electromagnet 5 and the second electromagnet 6 are respectively mounted on the support frame 7 on the base 1 and fixed. Setting the first electromagnet 5 and the first electromagnet The conveyor belts on one side of the fifth side are opposed to each other in a direction perpendicular to the direction in which the linear guide rails 2 extend; the conveyor belts on the side of the second electromagnets 6 and the second electromagnets 6 are opposed to each other in a direction perpendicular to the direction in which the linear guide rails 2 extend. Thus, when the slider 3 moves along the linear guide 2, the conveyor belt engaged with the moving slider 3 always fits with the first electromagnet 5 or the second electromagnet 6 of the suction slider 3, which can cause the slider 3 and The belt is more securely joined.

However, during the movement of the slider 3 to the conveyor belt on one side and along the linear guide 2, the first electromagnet 5 or the second electromagnet 6 on the side of the joined conveyor belt also has friction with the conveyor belt 4, and the friction will occur. Affects the conveying speed of the conveyor belt, which in turn affects the moving speed of the slider. Therefore, in order to reduce the friction between the conveyor belt 4 and the first electromagnet 5 or the second electromagnet 6, between the conveyor belt 4 and the first electromagnet 5, and between the conveyor belt 4 and the second electromagnet 6 A row of ball supports.

Further, the conveyor belts 4 on both sides of the linear guide 2 are the same conveyor belt. Two driving wheels 8 are disposed on the base 1, and the two driving wheels 8 are respectively located at two ends of the linear guide 2 and spaced apart from each other with the linear guide 2. The conveyor belt 4 is sleeved with two driving wheels 8. The rotating shafts of the two driving wheels 8 are perpendicular to the upper surface of the base 1. The two driving wheels 8 are rotatable along the respective rotating shafts. One of the driving wheels 8 is fixedly connected with the base 1 and the other driving. The wheel 8 is coupled to a rotor (not shown) of the rotary electric machine 9 on the base 1. In operation, the rotary electric machine 9 rotates and drives the drive wheel 8 connected thereto to rotate, and the conveyor belt 4 rotates around the two drive wheels 8. Compared with the prior art, when the vibrating type pointer is reversed, the motor needs to switch the moving direction. When the sliding member of the embodiment is reversed, it is not necessary to switch the rotating direction of the rotating electric machine, thereby avoiding the problem that the reverse acceleration of the rotating electric machine is small. .

Also provided on the rotary electric machine 9 is a flywheel (not shown) that surrounds the rotor and rotates synchronously with the rotor. When the slider 3 is reversed, the flywheel is used to increase the inertia of the rotor, and the inertia of the slider 3 is relatively reduced, so that the inertia of the rotor is much larger than the inertia of the slider 3, which not only relatively increases the reversal of the slider 3 The speed also prevents the sudden turn of the slider 3 from impacting the rotor. It is also possible to further provide that the slider 3 has a small mass, which can reduce the inertia effect of the slider 3 in the reverse direction and shorten the reverse time.

In the present embodiment, a displacement sensor (not shown) is disposed on the linear guide 2, The displacement sensor is used for monitoring the position of the slider 3. When the displacement sensor detects that the slider 3 reaches the end of the linear guide 2, it immediately sends a command to the control center, and the control center controls the first electromagnet 5 and the second electromagnet 6 in a timely manner. Power on and off. The displacement sensor also monitors the speed at which the slider 3 moves on the linear guide 2, and the control center controls the rotational speed of the rotary motor based on the feedback speed information. With the yarn guide of the embodiment, it is possible to achieve sensitive control of the reciprocating movement of the slider.

The engagement of the conveyor belt 4 with the slider 3 is achieved by frictional engagement with a strong frictional force, and the greater the frictional force, the closer the engagement of the two. In addition, the engagement of the conveyor belt with the slider can also be in the form of a toothed tessellation so that the engagement of the conveyor belt with the slider is stronger and tighter.

In the present embodiment, a guide finger 10 is disposed on the slider 3, the yarn guide finger 10 is fixed to the upper surface of the slider 3, and the yarn is wound around the yarn spool through the yarn groove in the yarn guide finger 10 On the tube. The yarn guiding finger 10 serves to guide the yarn to prevent the yarn from being broken and broken.

Second embodiment

Referring to FIGS. 3 and 4, the first electromagnet 15 and the second electromagnet 16 are located on the base 11 and are opposed to both side faces of the linear guide 12 in the extending direction. The linear guide 12 is provided with a soft magnetic material, and the linear guide 12 of the present embodiment has a soft magnetic material on both sides in the extending direction.

Referring to the principle of the yarn guide of the first embodiment, the principle of the yarn guide of the present embodiment is:

When the slider 13 is located at the first end I of the linear guide 12, the first electromagnet 15 is energized to attract the linear guide 12 to move toward the first electromagnet 15 and drive the slider 13 to engage the conveyor 14 on the side of the first electromagnet 15. ;

When the slider 13 reaches the second end II of the linear guide 12, the first electromagnet 15 is de-energized and the second electromagnet 16 is energized, the slider 13 is separated from the conveyor belt on the side of the first electromagnet 15, and the linear guide 12 is subjected to the The two electromagnets 16 are attracted to the second electromagnet 16 side, and the slider 13 is brought into engagement with the conveyor belt on the second electromagnet 16 side.

When the slider 13 is engaged with the conveyor belt on the side of the first electromagnet 15 or the second electromagnet 16 and moves along the linear guide 12, when the energized first electromagnet 15 or the second electromagnet 16 attracts the linear guide 12, At the attraction of the slider 13, the engagement of the slider 13 with the conveyor belt is made stronger.

It may also be that there is substantially no gap between the sliding member and the linear guide in a direction perpendicular to the extending direction of the linear guide rail, for example, the two contacts, so that the sliding member has no relative displacement with the linear guide rail in a direction perpendicular to the extending direction of the linear guide rail, and the sliding member and the sliding member are The belt is more tightly joined.

Compared with the surface area of the first embodiment slider opposite to the first electromagnet and the second electromagnet, the linear guide 12 of the present embodiment has a larger surface area opposite to the first electromagnet 15 and the second electromagnet 16, so that The electromagnetic force between an electromagnet 15 or the second electromagnet 16 and the linear guide 12 can be large. Thus, when the slider 13 reaches both ends of the linear guide 12, it can be accurately and quickly joined to the conveyor belt on the side of the first electromagnet 15 or the second electromagnet 16 that is energized. Moreover, when the slider 13 reciprocates, the large electromagnetic force makes the engagement of the slider 13 and the conveyor belt 14 closer and less likely to loosen.

Referring to FIGS. 3 and 4, two opposite support members 18 and a cross member 19 between the opposite support members 18, the extending direction of the cross member 19 and the linear guide 12 are respectively disposed on the base 11 at both ends of the linear guide 12. Vertical to each other. The linear guide 12 has a through hole (not visible in the drawing) extending in the extending direction of the beam 19, and the beam 19 passes through the through hole. The width of the through hole along the extending direction of the beam 19 is smaller than the length of the beam 19, so that the straight line The guide rail 12 is reciprocally movable in the direction in which the beam 19 extends. When the first electromagnet 15 or the second electromagnet 16 energizes and attracts the linear guide 12, the linear guide 12 moves in the extending direction of the cross member 19. Moreover, the support member 18 also functions to restrict the movement of the linear guide 12 in the direction in which the guide rail direction 12 extends.

It can also be that a roller connection is arranged between the linear guide and the base. The linear guide can be moved by the roller on the base in a direction perpendicular to the linear guide.

In addition, in order to make the engagement between the slider 13 and the conveyor belt 14 more compact, the baffle 17 is disposed on the other side of the conveyor belt 14 opposite to the linear guide rail 12, and the conveyor belts on both sides of the linear guide rail 12 are provided with two flaps 17, The baffle 17 is opposite the conveyor belt 14. When sliding When the piece 13 is moved along the linear guide 12, the belt engaged with the slider 13 is always fitted to the shutter 17, so that the engagement of the slider 13 with the belt 14 is more tight. The surface on which the baffle 17 is attached to the conveyor belt 14 is smooth, and the friction between the two can be reduced. In addition to this, a dense roller row may be provided on the surface of the baffle 17 opposite to the conveyor belt 14 instead of sliding friction.
