Description

Pull winding device of veneer veneer

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulling-and-winding apparatus for winding a veneer single plate (hereinafter referred to as a single plate) carried in a direction orthogonal to a fiber.

As a conventional pulling-and-pulling device of a single plate, for example, an apparatus disclosed in Japanese Patent Application Laid-open No. 57-53306 has been proposed.

32, the main part of the apparatus has a plurality of carry-in conveyors 151 having a flow center on the carry-in side of the single plate 150 and capable of flowing out on the carry-out side, A touch roll 152 which is arranged in a divided manner in a direction orthogonal to the conveying direction and which is driven to rotate at a slightly higher speed than the carry-in conveyor 151, and a touch roll 152 which elastically supports the touch roll 152 in the arrow direction (Not shown) and a magazine roll 153 for pulling and winding the single plate are sequentially provided to form a winding-up roll 154.

The force for pressing the touch roll 152 to the winding roll 154 is comparatively large because the winding roll 154 is rotated by the frictional force from the touch roll 152. However, The touch roll 152 and the take-up roll 154 are close to the contact between the circle and the circle, and the contact length between the touch roll 152 and the take-up roll 154 is short in the transport direction. The force per unit area, or stress, is the cost. As a result, the end plate is pulled by the large stress between the touch roll 152 and the winding roll 154.

The end plate 150 cut from the raw wood into the blade is conveyed irregularly in a direction orthogonal to the fiber in the conveying direction and is conveyed in a finely waving state and a large number of breaks called breaks are formed, It is easy to be elastically deformed. Further, due to the difference in the material of the part, the amount of deformation varies even if the same force is applied.

As a result, the end plate 150 is pulled as described above, so that the end plate 150 is extended to the left side, which is the side to be carried in than between the touch roll 152 and the winding roll 154 in Fig. 32, There is a problem that the single plate 150 can not go along the course and is displaced from a predetermined position so as to be pulled and hit against the machine frame of the winding apparatus to break the single plate 150. [

In addition, as shown in Fig. 32, at the positions on both the loading side and the both ends in the direction perpendicular to the carrying direction, between the touch roll 152 and the winding roll 154 of the single plate 150 being conveyed as described above, The swollen portion 150a is formed and the swollen portion 150a of the swollen portion is wound around the winding reel 153 by being pulled in such a state that the swollen portion 150a is overlapped There has been a problem of lowering the yield by degrading the quality of the product and damaging it at the position.

Next, a first embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a frontal explanatory view, and Fig. 2 is a plan explanatory view showing a magazine roll 35 and a yarn supply nozzle 31, which will be described later, when viewed in the direction of the arrow from the one-dot chain line A-A in Fig.

(Not shown) that is rotatably supported by a bearing 1 fixed to a base (not shown) and rotatably driven by a motor (not shown) Eight pulleys 3 (wheel axles) are fixed at intervals in the axial center line direction of the rotating shaft 2, that is, in Fig. 2 in the vertical direction. 8 belts 4 can also be mounted on the pulleys 3 by placing the belts 4 across the pulleys 3 (not shown) provided on the upper side in the running direction of the belts 4, Respectively, in the direction of the arrow in Fig. A rotation measuring instrument 43 such as a rotary encoder for measuring the number of revolutions per unit time of the rotary shaft 2 is connected to the rotary shaft 2 in order to detect the speed and travel distance of the belt 4. [

2, a touch roll 6, which is pressed on the periphery of the urethane rubber 5, is disposed on the upper side of the rotating shaft 2 in the running direction of the belt 4 (hereinafter referred to as upper side) The urethane rubber 5 in the portion opposed to the yarn supplying nozzle 31 described below is cut out to be smaller in width than the groove 7 and the groove 7 continuing in the rotating direction of the touch roll 6 The groove portions 8 are formed at intervals in the direction of the axis line of the touch roll 6.

As shown in Fig. 2, a roll 11, on which a shaft 10 is rotatably supported by a bearing 9 fixed to a base (not shown), is disposed above the touch roll 6, The first arm 12 is fixed at the end of the shaft 10 of the first arm 12.

The first arm 12 is a side view explaining the side view of the arrow from the one-dot chain line BB in Fig. 2 and shows the first arm 12 and its associated components only, 13 are rotatably provided with a bearing 14 interposed therebetween. Therefore, the touch roll 6 can rotate in the direction of the arrow as the center of rotation of the shaft 10. A stopper 16 for restricting the rotation of the first arm 12 in the clockwise direction in FIG. 3 and a stopper 16 for restricting the rotation of the first arm 12 in the clockwise direction are provided at the lower side of the shaft 13, And a stopper 17 for restricting rotation in the counterclockwise direction. The first arm 12 positioned at the lower side of FIG. 2 has been described. The first arm 12 located at the upper side in FIG. 2 is also provided with the compression spring 15 And stoppers 16 and 17, respectively.

By providing the compression spring 15 in this way, the weight of the touch roll 6 and the first arm 12 is supported and the first arm 12 is held in a substantially horizontal state.

Further, the winding roll radius detecting member for detecting the radius of the winding roll 66 to be described later is configured as follows.

As shown in Fig. 3, an L-shaped second arm 18 is fixed to the first arm 12 on the lower side of Fig. 2, and an air cylinder 19 fixed on the base of the second arm 18 Thereby fixing the load cell 20 to the tip of the piston rod 19a. The touch roll 6 is pressed against the magazine roll 35 or the winding roll 66 by the force of pushing up the lower end portion 18a of the second arm 18 to the air cylinder 19 Compressed air of a predetermined pressure is injected so as to be in pressure contact with a force of 5 kg.

3, a virtual line indicated by an alternate long and two short dash line passing through the rotation center s1 of the rotation shaft 13 of the touch roll 6 and the rotation center s2 of the rotation axis 10 of the roll 11, , The distance between s2 and s1 is divided by the distance between s2 and s3, and a value obtained by dividing the distance between s2 and s3 by a distance of about 5 It may be determined in relation to the inner diameter of the cylinder tube so that the force of the value obtained by multiplying by the kilogram can be issued by the piston rod 19a.

Further, the compressed air having the determined pressure is injected into the cylinder tube so that the piston rod 19a is fully extended, and then the valves of the intake port and the exhaust port of the compressed air are closed. Thus, when the piston rod 19a is pushed into the cylinder tube by the external force acting on the load cell 20, the air in the cylinder tube is compressed, so that the force that is greater than the pushing force is proportional to the pushed amount Is set as a reaction to the piston rod 19a, and this force is measured by the load cell 20. [

The length of each member is determined so that a slight gap is created between the load cell 20 and the lower end portion 18a of the second arm 18 in a state in which no external force acts on the touch roll 6. [

On the other hand, in the cross-sectional view of the one-dot chain line CC in Figs. 2 and 2, arrows are shown and the compressed air set at the first pressure or the second pressure is injected into the air cylinder 26 Shaped support base 25 in the state of passing over the pulleys 3 and all the belts 4 traveling in the reverse direction, that is, in the leftward direction in Fig. 4, to the pulley 3 and the touch roll 6 ). An air cylinder 26 is fixed to the support base 25 so as to correspond to each of the belts 4. An upper end portion of each belt 4 is fixed to the support base 25 by a bearing 27, So as to have a width equal to that of the belt 4.

Although the belt 4 provided with the air cylinder 26 and the flat plate 28 as described above does not show all of them, the single plate 65 having a length in the fiber direction of about 1,800 mm, for example, The eight belts 4 are divided into two groups of four on both sides from the center in the direction orthogonal to the running direction of the belt 4 so that the belt 4 is divided into two groups, The four belts 4 from the right end when viewed in the running direction are referred to as the first group for convenience and the four belts 4 from the left end as viewed from the top in Fig. 2 are also referred to as the second group for convenience.

The piping is connected to these two groups of air cylinders 26 as shown in Fig. That is, piping is connected from the air compressor 76 for obtaining compressed air through the pressure reducing valves 77, 78, 79 and 80 to the electromagnetic valves 81 and 82 as the direction switching valves, One group of the air cylinders 26 and the electromagnetic valves 82 are connected to the second group of air cylinders 26, respectively.

In the pressure reducing valves 77 and 79, the pressure is controlled to the first pressure described later, and the pressure reducing valves 78 and 80 control the second pressure to be described later, respectively.

The first pressure is defined as the distance between the front end of the piston rod 26a stretched by the injection of the compressed air into each of the air cylinders 26 of the belt 4 of one group of the belts 4 divided into the two groups, 28 so that each of the belts 4 in one of the groups has a force of about 5 kilograms applied to the magazine roll 35 or the winding roll 66, It is the same pressure as it is pressed by a force of 20 kilograms.

On the other hand, the second pressure is applied to each of the air cylinders 26 of the other group belt 4 of the belt 4 divided into the two groups to extend the piston rod 26a, And the pressure is such that the force from the belt 4 hardly acts on the magazine roll 35 or the winding roll 66. [

8, the piston rod 26a of the air cylinder 26 into which the first or second pressure is injected is pressed against the flat plate 28, The entirety does not protrude in the cylinder tube and the single plate is sequentially wound around the magazine roll 35 in this state to form the winding roll 66. When the winding is performed in this manner, the magazine roll 35, that is, The length and position of each member are determined so that the piston rod 26a further protrudes and follows in the cylinder tube so that the belt 4 can be continuously pressed onto the winding roll 66. [

Further, even if the piston rod 26a further protrudes in the cylinder tube as described above, or if the piston rod 26a is pressed against the cylinder tube by a reverse force, For example, by closing the exhaust port of the compressed air of the air cylinder 26 and connecting the exhaust port and the reducing valve (not shown) with a long hose so as not to significantly change the force acting on the winding roll 35 or the winding roll 66, The volume at which the compressed air of the determined pressure is accommodated is made large.

With these settings, the belt 4 is lifted up as shown in Fig. 4 with the flat plate 28 rising.

A thin distal end 31a of a size large enough to be inserted into the groove 8 is provided on the upper side of each groove 8 of the touch roll 6 and is guided by the air hose (Not shown) to the chamber 30 after the supply of the compressed air to the chamber 30 by supplying the compressed air to the chamber 30 by the compressed air, and when the external force is applied, A nozzle 31 capable of being pulled out is arranged so that the nozzle 31 can be moved up and down and back and forth as described later by the operation of an air cylinder (not shown).

The detector 42, which is made of a rotary encoder or the like, detects the distance x of the magazine roll 35 rising from the initial position, which will be described later, by measuring the number of revolutions of the male screw 38 is connected to the roll 40 .

A support base 45 on which a female thread is formed to be engaged with the male screw 38 is disposed above the male screw 38 and the support base 45 is associated with the support 36 as follows. 1 are formed as shown in FIG. 6, which is a cross-sectional view in the direction of the arrow in the one-dot chain line DD in FIG. 1, so that the support base 45 is provided with a cut- And passes through the joint 46.

A vertical guide 47 is also formed in the strut 36. The linear bearing 48 engaged with the guide 47 is fixed to the support 45 so that the support 45 is guided 47 in the vertical direction.

The holder base 51 of the magazine roll 35 is fixed to the tip of each support base 45. As shown in Fig. 7, which is a cross-sectional view in the direction of the arrow in the one-dot chain line EE of Fig. 1, the left and right support bases 51 of Fig. And the right side support 51 of Fig. 1 is configured similarly.

In addition,

The weight of the magazine roll 35 is configured such that the bearing 33 does not fall upward from the support portion 52 even if it receives upward force from the belt 4 and the touch roll 6 as described later do.

In these configurations, the force acting on the load cell 20 from the second arm is always detected, and the manual signal from the driver, the information from the load cell 20, the detector 42 and the rotation measuring instrument 43 And a control device 60 for outputting a signal for controlling the motor for rotating the rotary shaft 2, the servo motor 41 and the electromagnetic valves 81 and 82 as follows.

That is, when the rotary shaft 2 is not rotationally driven and the holding table 51 is descending, the load detected by the load cell 20 is lower than the value of the force of pushing upward, When the load cell 51 receives a signal from the load cell 20 that is about 1 percent greater than the raising force, the both ends of the male screw 38 are rotated so as to stop the lowering operation and subsequently operate to raise the load, A signal for controlling the servomotor 41 is sent so as to stop the rotation of both male threads 38 when receiving a signal that is smaller than the force of the load from the load cell 20. [

Further, as will be described later, by a manual input from the driver, a signal for rotating the servomotor 41 in a desired direction, a signal for actuating a motor for rotating the rotary shaft 2, A signal for actuating each of the solenoid valves 81 and 82 and a signal for actuating each of the solenoid valves 81 and 82 so as to inject compressed air of the first pressure into the air cylinders 26 of the first group and inject compressed air of the second pressure into the air cylinders 26 of the second group, A signal for supplying compressed air by an air hose (not shown) in the direction of the tip end 31a of the nozzle 31, a signal for causing the resistor 30 to press-contact the chamber 30, a nozzle 31 to a cylinder (not shown) As will be described later, signals to be moved in the vertical and horizontal directions, respectively.

When the rotary shaft 2 is rotating, the travel distance is calculated based on the information of the speed of the belt 4 from the rotation measuring device 43 and the elapsed time of the belt 4 traveling at the speed. The compressed air of the second pressure is injected into each of the air cylinders 26 of the first group while each of the air cylinders 26 of the second group is injected with the compressed air of the first group A signal is sent to each of the solenoid valves 81 and 82 so as to inject compressed air at the same time to operate the directional control valve at the same time. When the travel distance calculated again after sending the signals to the solenoid valves 81 and 82 reaches 500 mm, the compressed air of the first pressure is injected into each of the air cylinders 26 of the first group, while the compressed air of the second group Similarly, the air cylinder 26 is supplied with compressed air of a second pressure, and a signal is sent to the solenoid valves 81 and 82 to simultaneously operate the directional control valves. And sends an operation signal to the solenoid valves 81 and 82 so as to alternately change the pressures of the air cylinders 26 of the first group and the second group.

Further, when a signal detected by the rotation measuring instrument 43 is inputted to the rotary shaft 2 and the rotation speed per unit time of the rotary shaft 2 is inputted, the load detected by the load cell 20 is shifted upward If the state continues for a predetermined number of revolutions of the magazine roll 35, for example, a quarter of a turn, the two male screws 38 are lifted so that the holder 51 is lifted up. When the magazine roll 35 continues to rotate for one-fourth of the rotation time, the rotation of the male screw 38 is stopped. In this state, (41).

Here, the time for the magazine roll 35 to rotate by 1/4 turns, as described below, from the initial state to the winding roll 66 by winding the end plate on the magazine roll 35, The magazine roll 35 increases and increases while the magazine roll 35 is raised. However, the time for the quarter rotation at an arbitrary point is obtained as follows.

The distance at which the supporter 51 rises from the initial position is x, the radius of the magazine roll 35 is y, the traveling speed of the belt 4 is z, and the winding roll 66 rotates by 1/4 When the time is t and the circumferential rate is pi, the length of the outer circumference of the take-up roll 66 at time t is zt, and the length of the take-up roll 1 is 2 pi, the radius of the take- ). Since this length zt is equal to one-fourth of the length 2π (x + y), t is calculated to be π (x + y) / 2z.

This time t is calculated by the control device 60 to which the information of the distance x from the detector 42 and the information of the speed z from the rotation measuring device 43 are inputted and further the control device 60 calculates the time The load cell 20 determines the information of the load inputted from the load cell 20 and, if the above condition is satisfied, sends out a signal for controlling the servomotor 41 as described above.

The control device 60 receives the respective signals, and sends signals for controlling them as described above.

The first embodiment is configured as described above, and the initial state is prepared as follows.

A signal is output from the control device 60 by manual input from the driver and the respective solenoid valves 81 and 82 are operated to inject compressed air of the first pressure into each of the air cylinders 26 of the first group While compressed air of the second pressure is injected into each of the air cylinders 26 of the second group.

Then, similarly, the servomotor 41 is operated by manual operation of the driver to rotate both male screws 38 to move the holding table 51 to a predetermined position above the position shown in Fig. 1 to stop and wait Then, the both end bearings 33 of the magazine rolls 35 are placed on the support stand 51 and the magazine rolls 35 are supported. Then, similarly, the servomotor 41 is operated by the manual input from the driver, and the both male screws 38 are rotated in the reverse direction to lower the support 51. [

4, and the magazine roll 35 is constructed so that the weight of the magazine roll 35 is sufficiently large, the belt 4 and the touch roll 6 6) is pushed downward. The touch roll 6 is pressed downward so that the first arm 12 which rotatably holds the rotation shaft 13 of the touch roll 6 is rotated in the clockwise direction in Fig. The lower end 18a of the second arm 18 pushes the load cell 20. Therefore, when the piston rod 19a of the air cylinder 19 to which the load cell 20 is fixed is pushed into the cylinder tube and the air in the cylinder tube is compressed to increase the pressure, A large force is applied to the piston rod 19a as a reaction and a force larger than the upward force is applied to the load cell 20 from the lower end 18a of the second arm 18 to the bottom of the piston rod 19a, As shown in Fig.

The controller 60 receives the signal and the servo motor 41 receives the signal from the load cell 20 as described above so that the force of the load cell 51 The magazine roll 35 stops to descend and then raises the signal.

When the magazine roll 35 is raised, the pressing force of the touch roll 6 downward is reduced, and the pressing force of the lower end portion 18a of the second arm 18 against the load cell 20 also becomes small. On the other hand, since the compressed air in the cylinder tube of the air cylinder 19 gives the piston rod 19a a force which is about 1 degree greater than the upward pushing force, the force balance is collapsed and fixed to the piston rod 19a The load cell 20 pushes the lower end 18a of the second arm 18 upward. The first arm 12 integral with the second arm 18 is rotated in the counterclockwise direction in FIG. 3 so that the touch roll 6 provided on the first arm 12 is rotated in the magazine roll 35, As shown in Fig.

In addition, the balance of the force is reduced, and the piston rod 19a gradually comes out of the cylinder tube of the air cylinder 19. As the piston rod 19a comes out, the pressure increasing in the cylinder tube gradually decreases And the force applied to the piston rod 19a is smaller than the force for pushing up the piston rod 19a, the force acting on the load cell 20 is also smaller than the force for pushing it upward.

As a result, a signal having a force smaller than the pushing force of the load cell 20 is sent out from the load cell 20, and the control device 60 receiving the signal outputs the signal to the servomotor 41, And stops the supporter 51. In this case, as shown in Fig.

As a result, the belt 4, the touch roll 6 and the magazine roll 35 are sectional views of the one-dot chain line FF in Fig. 2 in the direction of the arrows, and the magazine roll 35 shown by two- , And waits at the positional relationship shown in Fig. 8 as a solid line. That is, the urethane rubber 5 portion of the touch roll 6 is pressed against the circumferential surface of the magazine roll 35. In the groove portion 7, as shown in Fig. 4, the flat plate 28 is pressed by the cylinder 26 The belt 4 is pressed against the circumferential surface of the magazine roll 35 by being pushed up. In this state, even if the piston rod 26a of the air cylinder 26 is not yet entirely projected in the cylinder tube and the magazine roll 35 is slightly raised from the state, the piston rod 26a The belt 4 can continue to be pressure-bonded to the magazine roll 35 by further projecting and following.

After the abnormal initial state is set, pulling is performed as follows.

4, compressed air is supplied to the tip of each nozzle 31 (not shown) through an air hose (not shown) as an input signal by a manual operation by the driver in a state in which the resistor 30 is not pressure- 31a. 9, when the seal 30 is moved beyond the magazine roll 35 and between the touch roll 6 and the roll 11, as shown in Fig. 9, .

Next, an air cylinder (not shown) is operated by an input signal by a similar manual operation to move the nozzle 31 to the lower position of the running position of the belt 4, as shown in Fig. 10, The nozzle 31 is horizontally moved to the left as well and the leading end 31a enters the groove portion 8 which is positioned immediately below the magazine roll 35 and waits. At this time, the upper end of the thread 30 is also downwardly intersected with the belt 4 as shown in Fig.

In this state, a resistor is pressed against the yarn 30 by an input signal by a manual operation of the driver, and then a signal for operating a motor for rotating the rotary shaft 2 is issued, and the pulley 3 is rotated The magazine roll 35 in contact with the belt 4 is rotated by the frictional force from the belt 4 and is pressed against the magazine roll 35 The touch roll 6 is rotated by the frictional force from the magazine roll 35. [

The control device 60 calculates the distance traveled from the rotation measuring device 43 by receiving information on the speed of the belt 4 and when the calculated travel distance reaches 500 mm, A signal is sent to the valves 81 and 82 so that the directional control valves are simultaneously operated and the compressed air of the second pressure is injected into each of the air cylinders 26 of the first group, The compressed air of the first pressure is injected into each of the air cylinders (26). Whenever the travel distance becomes 500 mm as described above, an operation signal is similarly sent to the solenoid valves 81 and 82 to alternately change the pressures of the air cylinders 26 of the first group and the second group, That is, when the pressure of one air cylinder 26 of the first and second groups is set to the first pressure and the pressure of the other air cylinder 26 is set to the second pressure, Alternately.

As a result, the magazine roll 35 is subjected to a force for rotating, mainly from the belt 4 of the group in which the pressure of the air cylinder 26 has become the first pressure. Even when the end plate 65 is wound around the magazine roll 35 to form the winding roll 66 as described later, the pressure of the air cylinder 26 is increased mainly from the belt 4 of the group of the first pressure , And receives a force to rotate.

Next, as shown in Fig. 12, a veneer lace (not shown) is cut at a speed equal to the traveling speed of the belt 4, and the length of the veneer lace (not shown), which is continuously conveyed in the direction orthogonal to the fiber direction, (65) onto the belt (4). Thereupon, the end plate 65 is further continuously conveyed by the belt 4, and the end plate 65 of the end plate 65 is moved in a state in which the end of the end portion of the end plate 65 is bent and threaded as shown in Fig. When the tip of the single plate 65 passes between the rotating touch roll 6 and the magazine roll 35, the thread 30 at the tip end of the single roll 65 contacts the touch roll 6 rotating like the single plate 65, The yarn 30 is conveyed at the speed at which the magazine roll 35 is rotated so that the yarn 30 is always subjected to the tension at the tip 31a of the nozzle 31 State. The tip end of the single plate 65 that has passed between the touch roll 6 and the magazine roll 35 is positioned at the tip end of the nozzle 31 from the nozzle 31 The pulled-out yarn 30 is guided along the magazine roll 35 by a portion that runs above the belt 4, that is, a portion indicated by 30a in FIG. 14 to be described later, And is wound integrally with the yarn 30 positioned on the outer side in turn and wound around the rotating magazine roll 35 sequentially to form a winding roll 66 as shown in Fig.

In the above-described pulling-and-winding apparatus, since the pressures of the air cylinders 26 of the first group and the second group are changed as described above, the problem in the conventional apparatus is solved as follows.

That is, due to the material, the end plate 65 is pulled between the belt 4 and the winding roll 66 by the pressure of each air cylinder 26 on the side of the first group, for example, on the side of the first group, , A swollen portion 65a is formed as shown in Fig. 15 from the state of Fig.

When the belt 4 travels for 500 mm after the pressure of each air cylinder 26 reaches the first pressure on the first group side, the pressure of each air cylinder 26 of the first group is increased to the second pressure And the touch roll 6 is also pressed against the winding roll 66 with a weak force as described above so that the swollen portion 65a is in contact with the belt roll 4 When passing between the winding roll 66 and the touch roll 6, the winding roll 66 is wound in a slightly loosened state without being closely pulled, and the state of FIG.

Even if the pressure of each air cylinder 26 on the second group side becomes the first pressure and the end plate 65 is closely pulled and largely waved, it is wound in a slightly loosened state to become the winding roll 66.

Even if the swollen portion 65a occurs as shown in Fig. 15 during the single-plate pulling-off, as described above, since the single plate 65 is continuously pulled as in the conventional device, the amount of elongation on the carry- There is no possibility that the yield is lowered because the single plate 65 is folded and rolled and the bent portion appears on the product as a blemish to deteriorate the quality or tear from the position.

In this pull-pull winding, the pressure of the air cylinder 26 temporarily becomes the first pressure due to the difference in the material of the end plate, so that the swollen portion 65a occurs as shown in Fig. 15 only on the first group side, The winding rolls 66 are tapered in such a manner that the radii of the first group are successively increased as compared with the second group side and at this point the magazine roll 35 is in the correct position, Press the touch roll (6) down.

The touch roll 6 is held rotatably on the first arm 12 so that the first arm 12 is fixed to the shaft 10 and the shaft 10 is fixed to the first arm 12. [ The touch roll 6 is rotated about the shaft 10 in parallel with the roll 11 even if the touch roll 6 is pushed down toward the first group by being supported by the bearing 9 so as to be rotatable Rotate at the same angle.

3, the first arm 12 rotates in the clockwise direction so that the lower end 18a of the second arm 18 presses the load cell 20 and the piston rod 19a of the air cylinder 19 ) Is gradually pushed into the cylinder tube. As a result, as described in the above-described initial state, the pressure in the cylinder tube increases, and the force detected by the load cell 20 becomes greater than the force to push it upward.

The force acting on the load cell 20 is always detected as described above and is transmitted to the control device 60 so that the detected value becomes about one order of magnitude higher than the upward force of the magazine roll 35, The control device 60 gives a signal to the servomotor 41 to raise the retainer 51 in the above state when the control device 66 continuously continues to rotate about 1 / Whereupon the magazine roll 35 is lifted to reduce the force of the touch roll 6 being pressed downward by the winding roll 66 and to prevent the value measured by the load cell 20 from being lower than the force Further, a signal for stopping the rising of the supporter 51 is continuously outputted to the servomotor 41 during the time period when the magazine roll 35, that is, the winding roll 66 rotates by 1/4.

When the phenomenon that the end plate is pulled and rolled as it waved only on the side of the first group which has occurred temporarily after repeating the rising and stopping of the supporter 51 several times is eliminated, the pulling and winding of the end plate is continued, On the side of the second group having a small radius, the end plate is wound loosely and the radius of the second group gradually increases. As a whole of the winding roll 66, the shape of the tapered state is corrected and becomes substantially a circumferential state.

As the radius of the winding roll 66 is sequentially increased by the winding of the end plate 65 after the circumferential state has been established and the belt 4 and the touch roll 6 have a larger radius of the winding roll 66 It is pushed down.

In this case as well, in FIG. 3, the first arm 12 is clockwise. When the force detected by the load cell 20 becomes about 1 percent higher than the pushing force of the load cell 20, the magazine roll 35 is raised by the operation signal from the control device 60 to which the signal is inputted When the force detected by the load cell 20 becomes smaller than the pushing force of the load cell 20, the magazine roll 35 also stops rising by the operation signal from the control device 60.

The pulling and winding of the end plates is performed while performing these operations.

In the first embodiment, since the force of the air cylinder 26 is made to act only by the belt 4, it is possible to arrange the two pulleys spaced apart in the carrying direction of the end plate, The mass of the moving member is small as compared with the case where the force of the air cylinder is applied to the pulley at the lower side in the same direction with the pulley of the pulley as the rotational center of rotation and the operation time interval is short, .

In the case where the belt 4 is a thin plate having a thickness of, for example, 0.6 mm, which is made of a weak material, in the present embodiment, only the belt 4 is rolled up and wound around the winding roll 66, The urethane rubber 5 of the touch roll 6 is pulled and wound on the end plate 65 in a state in which the end plate 65 is in contact with a small force as described above, It prevents winding and winding.

3, the tip of the piston rod 19a is directly brought into contact with the lower end portion 18a of the second arm 18 without using the load cell 20 for detecting the force in Fig. 3, 19 are set as described above and are used to detect whether or not the second arm 18 has been rotated to a predetermined position during the pulling operation by using the limit switch 86 as shown in Fig. There are the following problems. In other words, it is difficult for the second arm 18 to precisely detect the fine rotational movement of the limit switch. When the touch roll 6 is pushed down by the take-up roll 66 and the limit switch An excessive force acts on the take-up roll 66 from the touch roll 6 until it is detected. In the case of a single piece thin plate or a single piece weak in material, It tears away.

The winding roll radius detecting member is disposed on the outer circumferential surface of the take-up roll so that the contact member such as the touch roll (6) movable in the take-up roll radius direction and the load cell A change in the winding roll radius can be detected as a force acting on the wind-up roll 66 from the touch roll 6. By the value of this force, the holding member of the magazine roll and the traveling body The excessive force does not act on the winding roll, and the above problem does not occur.

When the winding roll 66 reaches a predetermined radius, the pulling operation is stopped, and a spool member (not shown) is attached to the both end rotating shafts 35a of the magazine roll 35, (35) is lifted up to a predetermined position and rewound.

16, the bearing 33 mounted on the rotary shaft 35a at both ends of the magazine roll 35 is supported by a support portion (not shown in the drawing) of a V-shaped configuration like the support portion 52 of the supporter 51 So as to be rotatable. A plurality of belts 71 run across the rolls 70 driven by a motor (not shown) as shown by the arrows and run from the bottom to the rolls 66 (not shown) The winding roll 66 is rotated in the direction of the arrow and the single plate 65 is rewound and conveyed to the next process. Further, 72 is a bobbin disposed below the adjacent belts 71 for winding the yarn 30 at the same speed as the belt 71 and recovering it.

Next, a second embodiment of the present invention will be described.

The second embodiment is different from the first embodiment in that members such as the load cell 20 for detecting the fall of the touch roll 6 and the touch roll 6 are not used,

do.

17, the pulley 3 is attached to the rotating shaft 2 driven by a motor (not shown) as in the first embodiment in the axial center line direction of the rotating shaft 2, that is, in the vertical direction in Fig. 17, 16, for example, are fixed at intervals.

The belts 4 run across the pulleys 3 (not shown), which are provided on the upper side in the traveling direction of the belts 4 to be described later with respect to the respective pulleys 3, 17 in the direction of arrows in the figure so that the nozzle 31 can move up and down between adjacent belts 4 in a position provided with the nozzle 31 which will be described later. 3) is fixed.

17, the magazine rolls 35 indicated by chain double-dashed lines are indicated by solid lines and the nozzles 31 are additionally provided to the pulleys 3 And the support frame 25 of the door shape is provided in a state of riding over all the belts 4 of the part running to the left in Fig.

As shown in Fig. 18, the support cylinder 25 is provided with an air cylinder 26 corresponding to each belt 4, and compressed air of a first pressure or a second pressure to be described later is injected, The upper end of the piston rod 26a of the piston 26 is supported so as to be rotatable by the bearing 27 so that its width is in contact with the lower end surface of the other end of the flat plate 28 such as the belt 4 .

The pressure of the compressed air injected into each air cylinder 26 is set as follows.

That is, as in the first embodiment, the sixteen belts 4 are divided into two groups of eight on both sides from the center in the direction perpendicular to the running direction of the belt 4, The eight belts 4 at the right end when viewed from the top are referred to as the first group for convenience and the eight belts 4 at the left end as viewed from the top in FIG. 2 are also referred to as the second group for convenience.

The air cylinders 26 of these two groups are piped as in the case of the piping shown in Fig. 5 in the first embodiment. That is, piping is connected from the air compressor 76 for obtaining compressed air to the electromagnetic valves 81 and 82 as the direction switching valves with the pressure reducing valves 77, 78, 79, and 80 interposed therebetween, One group of the air cylinders 26 and the electromagnetic valves 82 are connected to the second group of air cylinders 26, respectively.

In the pressure reducing valves 77 and 79, the pressure is controlled to the first pressure described later, and the pressure reducing valves 78 and 80 control the second pressure to be described later, respectively.

The first pressure means that the front end of the piston rod 26a elongated by injecting the compressed air into each air cylinder 26 of the group belt 4 on one side of the belt 4 divided into the two groups is connected to the flat plate 28, And the belt 4 of each group of the respective group is subjected to a force of about 2.5 kilograms on the magazine roll 35 or the winding roll 66, that is, on all four belts of the group in question, a force of about 20 kilograms As shown in Fig.

On the other hand, the second pressure is injected into each of the air cylinders 26 of the belt 4 of the other group of the belts 4 divided into the two groups so that the piston rod 26a extends, Is the same as the degree to which each belt 4 supports the plate 28 and the pressure is such that no force acts on the magazine roll 35 or the winding roll 66 from the belt 4. [

18, the piston rod 26a of the air cylinder 26 into which the first or second pressure is injected is in contact with the flat plate (not shown) 28, but the whole is not yet projected in the cylinder tube, and the end plates are sequentially wound around the magazine roll 35 from the state to form the winding roll 66. When this pulling winding is performed, the magazine roll 35 That is, the winding roll 66 is set to rise slightly. As the piston rod 26a further protrudes and follows in the cylinder tube, the belt 4 can be kept pressed to the winding roll 66 , And determines the length and position of each member.

Further, even when the piston rod 26a further protrudes and follows in the cylinder tube as described above, or vice versa, when the piston rod 26a is pushed into the cylinder tube, The compressed air discharge port of the air cylinder 26 is closed so that the force acting on the take-up roll 35 or the take-up roll 66 is not greatly changed, By connecting with the hose, the volume of compressed air at the determined pressure is maintained.

With these settings, the belt 4 is lifted up as shown in Fig. 18 by the flat plate 28 rising.

On the other hand, in the belt 4 positioned at the first end in the direction orthogonal to the running direction of the belt 4, that is, in Fig. 17, the belt 4 at the first position and the belt 4 located at the first position, A limit switch 86 serving as a winding roll radius detecting member which contacts with the plate 28 as a result of depression of the belt 4 by pressing down the belt 4 and outputs a signal indicating the ON state, (Not shown), respectively.

The nozzle 31 for supplying the yarn 30 can supply the compressed air in the direction of the front end 31a by an air hose (not shown) as in the first embodiment, (Not shown) is pressed against the yarn 30 after the yarn is supplied and supplied from the yarn introduction portion 31a. When the yarn 30 is subjected to an external force, a proper tension is applied to the yarn 30, As shown by the two-dot chain line, the center position of the adjacent belt 4 provided above the belt 4 and spaced apart by a distance at which the nozzle 31 can move up and down as described above, So as to be movable.

Although not shown in the drawings, the bearing 33, the support 36, the bearing 37, the male screw (not shown) provided on the rotary shaft 35a and the rotary shaft 35a at both ends of the magazine roll 35, 38, a bevel gear 39, a roll 40, a servo motor 41, a detector 42 including a rotary encoder, a rotation measuring instrument 43, a support 45, a cut portion 46, 47, the linear bearing 48, the supporter 51, and the V-shaped supporter 52 are similarly provided.

A motor for rotating the rotary shaft 2 and a servo motor 41 for rotating the rotary shaft 2 by inputting information from a driver, a detector 42, a rotation measuring instrument 43 and a limit switch 86, And a control device 60a for outputting a signal for controlling the solenoid valves 81 and 82 in the following manner.

That is, when the rotary shaft 2 is not driven to rotate and the holding table 51 is lowered, the belt 4 is pressed downward and a signal that is turned ON from at least one of the two limit switches 86 The rotation of the both male threads 38 is stopped when the both male threads 38 are rotated so as to stop the lowering operation of the retaining stand 51 and then to rise up and then receive a signal from the limit switch 86 in the OFF state, A signal for controlling the servo motor 41 is output.

Further, as will be described later, by a manual input from the driver, a signal for rotating the servomotor 41 in a desired direction, a signal for actuating a motor for rotating the rotary shaft 2, A signal for actuating each of the solenoid valves 81 and 82 to inject compressed air of the first pressure into the air cylinder 26 and inject compressed air of the second pressure into each of the air cylinders 26 of the second group, A signal for supplying compressed air to the chamber 30 by means of an air hose (not shown) in the direction of the tip 31a of each nozzle 31, a signal for bringing the resistor 30 into pressure contact with the chamber 30, As described later, signals to be moved vertically and horizontally are outputted alone.

When the rotary shaft 2 is rotating, the travel distance is calculated from the information of the speed of the belt 4 from the rotation measuring device 43 and the elapsed time of the belt 4 running at the speed, When the calculated travel distance becomes, for example, 500 mm, compressed air of the second pressure is injected into each of the air cylinders 26 of the first group while air cylinders 26 of the second group The pressure of the air cylinders 26 of the first group and the air cylinder 26 of the second group is alternately changed every time the corresponding travel distance becomes 500 mm, , 82 to operate the directional control valve simultaneously.

Further, when a signal detected by the rotation measuring instrument 43 is inputted to the rotary shaft 2 and the rotation speed per unit time of the rotary shaft 2 is inputted, a signal which is turned ON from at least one of the limit switches 86 When the ON state is continued for a predetermined number of revolutions of the magazine roll 35, for example, a quarter of a rotation, the both male screws 38 are rotated so that the retaining table 51 is caused to ascend, If the OFF state of the both limit switches 86 is inputted from the both limit switches 86 and the OFF state continues for a time period in which the magazine roll 35 similarly rotates by 1/4, the rotation of the both male threads 38 is stopped , And sends a signal for controlling the servo motor 41.

Here, the time when the magazine roll 35 rotates by 1/4 is obtained as in the first embodiment.

The control device 60 receives the respective signals and outputs a signal for controlling them as described above.

The second embodiment is configured as described above, and the initial state is prepared as follows.

The control device 60a outputs a signal by manual operation from the driver to operate the respective solenoid valves 81 and 82 to inject the compressed air of the first pressure into the air cylinders 26 of the first group, On the other hand, compressed air of the second pressure is injected into each of the air cylinders 26 of the second group.

The servomotor 41 is operated by the operator's manual operation to rotate both male screws 38 to move the holder 51 to a predetermined position above the position shown in Fig. And the bearings 33 at both ends of the magazine roll 35 are mounted on the support stand 51 to support the magazine roll 35. [ Then, similarly, the servomotor 41 is operated by the manual input from the driver, and the both male screws 38 are rotated in the reverse direction to lower the support 51. [

Thus, the magazine roll 35 is pressed downward by the belt 4, which is in contact with the belt 4, as shown in Fig. When the belt 4 is pushed downward, the limit switch 86 is turned on, and the signal is input to the control device 60a.

Thereupon, the control device 60a gives a signal to the servomotor 41 to stop the descent of the supporter 51 and then make the ascending operation, and the magazine roll 35 stops descending and then ascends.

When the magazine roll 35 is raised, the limit switch 86 is turned OFF and the control device 60 which has received the signal stops the rising of the supporter 51 to the servo motor 41 as described above And stops the supporter 51.

As a result, the belt 4 and the magazine roll 35 stand by in the positional relationship shown by the solid line in Fig. In this state, even if the entire piston rod 26a of the air cylinder 26 is not protruded from the cylinder tube yet, and the magazine roll 35 is slightly raised from the state, the piston rod 26a The belt 4 can continue to be pressure-welded to the magazine roll 35 by following the protrusion.

After setting the above initial state, pulling is performed as follows.

In Fig. 18, only the nozzle 31 is supplied with the yarn 30 from the nozzle 31, as in the first embodiment, with the input signal by the manual operation of the driver in the initial state in which the nozzle 31 waits at the position indicated by the chain double- , The nozzle 31 is similarly moved, and is indicated by the solid line in Fig.

In this state, a resistor is pressed against the yarn 30 similarly to the input signal by the manual operation of the driver, and the rotary shaft 2 is rotationally driven to rotate the pulley 3 to run the belt 4 in the direction of the arrow . The magazine roll 35 is rotated by the running of the belt 4.

The control device 60a similarly calculates the travel distance and sends an operation signal to the solenoid valves 81 and 82 every time the calculated travel distance becomes 500 mm, The pressure of the air cylinder 26 becomes the first pressure while the pressure of the air cylinder 26 of the other group becomes the second pressure.

The single plate 65 is guided by the seal 30 in the same manner as in the first embodiment so that the single plate 65 is integrally formed with the seal 30 located outside, And is sequentially wound on a rotating magazine roll 35 to form a winding roll.

As in the first embodiment, since the pressure of each air cylinder 26 of the first group and the second group is changed also in the pulling-and-winding apparatus described above, the problem in the conventional apparatus is solved similarly.

That is, even if the swollen portion occurs on the first group side where the pressure of each air cylinder 26 becomes the first pressure due to the material of the end plate 65, as shown in Fig. 15 in the first embodiment, When the pressure of each air cylinder 26 of the group becomes the second pressure, the swollen portion passes between the take-up roll and the belt 4, is wound in a slightly loose state to become a take-up roll, and the swollen portion disappears.

It is the same even if there is a swollen part on the side of the second group.

In this pulling-and-winding, for example, when the pressure of the air cylinder 26 becomes the first pressure so that the swollen portion 65a is generated only by the first group side and is loosely wound, , The winding roll 66 is slightly tapered as the radius of the first group is sequentially increased as compared with the second group side. Since the position of the magazine roll 35 is not changed at this point, Press down on the belt (4).

Thus, the belt 4 at the first end of the first group, that is, the limit switch 86 provided on the belt 4 at the first position in Fig. 17, is pressed by the flat plate 28, .

This signal is transmitted to the control device 60a so that when the ON state continues for a time period in which the magazine roll 35 or the winding roll 66 rotates by 1/4, the control device 60a controls the servo motor 41, A signal for raising the retainer 51 is generated. Whereupon the magazine roll 35 is lifted and the winding roll 66 is raised so that the limit switch 86 is turned OFF and this state is also the case where the magazine roll 35 or the winding roll 66 is a quarter The control device 60a sends a signal to the servo motor 41 to stop the elevation of the supporter 51. [

As a result, the take-up roll 66 is moved upward in parallel, and in this state, the take-up roll 66 is further rotated by the belt 4, and when the end plate 65 is wound, The single plate 65 is sequentially wound on the outside of the winding roll 66 in a direction substantially parallel to the magazine roll 35 and wound on the first group side relatively loosely and on the second group side loosely, As a whole of the winding roll 66, the shape of the tapered state is modified to become a substantially circumferential state.

When the radius of the winding roll 66 is sequentially increased by winding the single piece 65 after the circumferential state has been reached, the belt 4 and the touch roll 6 have a larger radius of the winding roll 66 And then pressed down.

In this case as well, the belt 4 is pushed down as the radius of the winding roll 66 becomes larger, at least one of the limit switches 86 is turned ON and inputted to the control device 60a, When the magazine roll 35 continues to rotate for one-fourth of the rotation of the magazine roll 35, the two male screws 38 are rotated so that the retaining table 51 is raised by the operation signal from the controller 60a, . Further, when a signal that is turned OFF from both limit switches 86 is inputted by the rise of the take-up roll 66 and this state is similarly continued for a time period in which the magazine roll 35 rotates by 1/4, 60a output a signal for controlling the servo motor 41 so as to stop the rotation of both male threads 38. [

As described above, when the pulling and winding of the single plate is performed and the radius of the winding roll becomes a predetermined amount, the winding is ended and the rewinding is performed as in the first embodiment.

Next, a third embodiment of the present invention will be described.

In the above-described two embodiments, the belt 4 is configured to change the force of pressure contact with the winding roll. In the third embodiment, a roll is used instead of the belt 4. [

This will be described with reference to the drawings.

19 is a partial explanatory view of a front view of the pull-up winder, and Fig. 20 is a cross-sectional explanatory view of the arrow direction of the one-dot chain line J-J in Fig.

Further, the rolls 90 and 91 are provided with belts 97 and 98, as shown in Fig. 20, across the belts 97 and 98 with a roll (not shown) As shown by the arrow, and the rolls 90 and 91 are rotated in the direction of the arrow.

These air cylinders are divided into two groups of air cylinders 93 and 94 and air cylinders 95 and 96, and are connected by piping as shown in FIG. That is, piping is connected from the air compressor 76 for obtaining compressed air to the solenoid valves 81 and 82 as the direction switching valves via the pressure reducing valves 77, 78, 79 and 80, The cylinders 93 and 94 and the electromagnetic valve 82 are connected to the air cylinders 95 and 96, respectively.

The first pressure is such that compressed air is injected into one group of air cylinders 93 and 94 divided into the two groups so that the roll 90 is sandwiched between the magazine rolls 35 with the belt 97 therebetween. Or when pressure is applied to the winding roll, the pressure is such that the pressure is applied by a force of about 20 kilograms.

The second pressure is the same as the second pressure. Compressed air is also injected into one of the groups, for example, the air cylinders 93 and 94 so that the roll 90 is sandwiched between the magazine roll 35 and the winding roll 66, The pressure is such that almost no force is applied to the magazine roll 35 or the winding roll 66. [

It is also possible to close the intake valves to the respective air cylinders 93, 94, 95 and 96 by operating signals to the solenoid valves 81 and 82 and also to actuate the exhaust valves to open, It is also possible to set the force of pressure contact with the magazine roll 35 or the winding roll 66 to be zero with the rollers 97 and 98 therebetween.

On the other hand, as shown in Fig. 19, limit switches 99 and 100 as winding roll radius detecting members are provided below the rolls 90 and 91 so that when the rolls 90 and 91 come down by a predetermined amount, Is sent.

Further, in order to reinforce the end plate, the dagger tape 101 wound around a reel on which a cohesive force is exerted when it comes into contact with water which is usually used is moved in the direction of the upper side of the left end portion of the roll 90 and the right side Place it near the end.

Although not shown in the drawings, the bearing 33, the support 36, the bearing 37, the male screw (not shown) provided on the rotary shaft 35a and the rotary shaft 35a at both ends of the magazine roll 35, 38, a bevel gear 39, a roll 40, a servo motor 41, a detector 42 including a rotary encoder, a support 45, a cut portion 46, a guide portion 47, a linear bearing 48, the retainer 51, and the V-shaped support 52 are similarly provided. The rotation driven roll for driving the belts 97 and 98 is provided with a rotation measuring device (not shown) such as a rotation measuring device 43 provided in the first embodiment.

In these configurations, a motor for driving the belts 97 and 98 by inputting information from an operator by hand, input from a detector 42, rotation measuring instrument 43 and limit switches 99 and 100, And a control device 60b which outputs a signal for controlling the servomotor 41 and the solenoid valves 81 and 82 as follows.

That is, when the belts 97 and 98 are stopped and the magazine roll 35 is lowered by the lowering of the supporter 51, the rolls 90 and 91 are pressed downward, When the signal from the at least one of the limit switches 99 and 100 is received from the at least one of the limit switches 99 and 100, the retaining base 51 stops the lowering operation and then rotates both male screws 38 When both of them are in the OFF state, a signal for controlling the servo motor 41 is output so as to stop the rotation of both male threads 38.

A signal for rotating the servomotor 41 in the desired direction, a signal for actuating the motor for driving the belts 97 and 98, a signal for actuating the motor for driving the belts 97 and 98, The air cylinders 93 and 94 are supplied with the compressed air of the first pressure and the air is supplied to the air cylinders 93 and 94 by closing the intake valves of the air cylinders 94 and 95 and opening the exhaust valves, Each of the cylinders 95 and 96 outputs signals for operating the solenoid valves 81 and 82 so as to inject compressed air of the second pressure.

When the belts 97 and 98 run, the speed information of the belts 97 and 98 from the rotation measuring instrument and the information of the elapsed time of the belts 97 and 98 running at the corresponding speed, The compressed air of the second pressure is injected into the air cylinders 93 and 94 and the compressed air is injected into the air cylinders 95 and 96 while the calculated travel distance becomes 500 mm as in the first embodiment The pressure of the air cylinders 93 and 94 and the air cylinders 95 and 96 are alternately changed each time the corresponding travel distance becomes 500 mm by injecting the compressed air of the first pressure, 82 to actuate the directional control valve at the same time.

Further, when at least one of the limit switches 99 and 100 is in the ON state (OFF state) when the belt 97 or 98 travels and a signal detected by the rotation measuring instrument is inputted to the running distance of the belts 97 and 98 per unit time, When the ON state is continued for a predetermined number of rotations of the magazine roll 35, for example, a quarter of a turn, the two male screws 38 are rotated If the OFF state of the magazine roll 35 is continued for a time period in which the magazine roll 35 is rotated by 1/4 in the state where the OFF state is inputted from both the limit switches 99 and 100 in this state, And outputs a signal for controlling the servomotor 41 so as to stop the rotation of the servomotor 41. [

Here, the time when the magazine roll 35 rotates by 1/4 is obtained as in the first embodiment.

The control device 60b receives the respective signals and outputs a signal for controlling them as described above.

The third embodiment is configured as described above, and the initial state is prepared as follows.

The control device 60b outputs a signal by manual operation from the driver to operate the respective solenoid valves 81 and 82 to inject compressed air of the first pressure into the air cylinders 93 and 94, The compressed air of the second pressure is injected into the cylinders 95 and 96, so that the piston rods of the respective air cylinders 93, 94, 95, and 96 are fully extended.

Subsequently, as in the first embodiment, both ends of the magazine roll 35 are provided on the support table 51 by manual operation of the driver. Then, the support table 51 is lowered, and the magazine roll 35 Is in contact with the rolls 90 and 91 with the belts 97 and 98 therebetween and the rolls 90 and 91 are pressed downward. The rolls 90 and 91 come into contact with the limit switches 99 and 100 with the belts 97 and 98 interposed therebetween so that the both limit switches 99 and 100 are turned ON, .

The control device 60b receiving the signal outputs a signal to the servomotor 41 to stop the descent of the supporter 51 and to make the supporter 51 ascend in the same manner as in the first embodiment, And then ascends.

Both of the limit switches 99 and 100 are turned OFF when the magazine roll 35 is lifted and the control device 60b which receives the signal turns on the servomotor 41 A signal for stopping the rise is issued, and the supporter 51 is stopped.

As a result, the rolls 90 and 91 stand by with the above-described force in pressure contact or contact with the magazine roll 35 with the belts 97 and 98 interposed therebetween.

Next, when the belt 97 or 98 is driven to rotate by an unillustrated roll across the belts 97 and 98 with an input signal by the manual operation of the driver, the magazine roll 35 is also rotated by the belts 97 and 98 .

The continuous single plate 102 cut by the veneer race at the same speed as the belts 97 and 98 in this state is guided over the belts 97 and 98 and the tip of the single plate 102 is wound around the magazine roll 35 The veneer race and the belts 97 and 98 are stopped at a point when the belt 97 and 98 have passed a small distance therebetween.

Subsequently, the intake valves of the air cylinders 93, 94, 95, and 96 are closed with the input signal by the manual operation of the driver, the injection of the compressed air is stopped, and the exhaust valve is opened to discharge the compressed air in each air cylinder into the air And the pressure of each of the air cylinders 93, 94, 95, and 96 is set to zero. Thus, the rolls 90, 91 are lowered together with the belts 97, 98 by their own weight. Thereafter, the magazine roll 35 is rotated in the counterclockwise direction in Fig. 20 with the leading end of the passed single plate 102 being placed on the circumferential surface of the magazine roll 35 manually by the driver, (102) is wound around the magazine roll (35) for several turns.

20, the magazine roll 35 and the belts 97 and 98 are wound in magazines, as shown in Fig. 20, to the leading end of the dagger tape 101 with the adhesive surface facing upward from above the belts 97 and 98, Is guided so as to abut the bottom surface of the end plate 102 wrapped around the roll 35 and adhered by the moisture of the end plate 102. [

Subsequently, each of the solenoid valves 81 and 82 is operated again with an input signal by a manual operation of the driver, compressed air of a first pressure is injected into the air cylinders 93 and 94, 2, the rolls 90, 91 are lifted and brought into contact with the magazine rolls 35 by the force described above, with the belts 97, 98 therebetween.

In this state, when the veneer race is restarted and the belts 97 and 98 run again, the veneer 102 is wound around the magazine roll 35 while the gum tape 101 continues to be adhered, (66) are successively overlaid.

The control device 60b calculates the travel distance in the same manner as the belts 97 and 98 travel and when the calculated travel distance reaches 500 mm, the air cylinders 93 and 94 are supplied with the compressed air of the second pressure A signal is sent to each of the solenoid valves 81 and 82 so as to inject the compressed air of the first pressure into the air cylinders 95 and 96 respectively so that the directional control valve is operated at the same time, The pressures of the air cylinders 93 and 94 and the air cylinders 95 and 96 are alternately changed.

As a result, even if a swollen portion occurs in the pulling and winding of the end plate, the pulling and winding is performed without any trouble by the same operation as in the above two embodiments.

The position of the magazine roll 35 is not changed as in the above two embodiments, so that the rolls 90 and 91 are pushed down and the limit switch 99, and 100) outputs a detection signal. Similarly, when the detection signal from the limit switches 99 and 100 continues for a time period in which the magazine roll 35 rotates by 1/4, the operation of the control device 60b causes the retainer 51 to rise , Both of the limit switches 99 and 100 do not output a detection signal due to the rise, and when the magazine roll 35 continues to rotate for 1/4 of the same time, the operation in the control device 60b The holding base 51 stops rising.

When the winding roll 66 has a predetermined radius, the veneer race and the belts 97 and 98 are stopped and the winding roll 66 is rotated at a predetermined position 16 to perform rewinding. In the present embodiment, since the inspection tape 101 is continuously wound around the single plate 102 for reinforcement of the single plate in place of the yarn, it is not necessary to collect the inspection tape 101 and the bobbin 72 is used I never do that.

Although the embodiment of the present invention has been described above, the following modifications may be made.

1. In the first to third embodiments, the belt 4 or the belts 97 and 98 are brought into contact with the take-up roll 66 at a second pressure, but they do not necessarily have to be in contact with each other. For example, A gap may be formed between the belt 4 and the winding roll 66 as shown in Fig. 22 without injecting compressed air into the air cylinder 26 as the second pressure.

2. In the first or second embodiment, the belt 4 is brought into pressure contact with the magazine roll 35 or the take-up roll 66. For example, as shown in Fig. 4, 3 is fixed and a flat plate 28 is provided on the back surface of the belt 4 across the pulley 3 so that the piston rod 26a of the air cylinder 26 is brought into contact with the flat plate 28 It may be configured as follows.

That is, as shown in FIG. 24, which is an explanatory view of the cross section of the one-dot chain line LL in FIGS. 23 and 23, which is a side explanatory view, the pulley 105 crossing across the belt 4 is inserted between a bearing (not shown) And is rotatably mounted on the pulley support 106. The pulley support 106 is guided in a vertical direction by a guide member 107 provided on a base (not shown). An air cylinder 108 is provided below the pulley support 106, So that the tip of the piston rod 108a is brought into contact with the pulley support 106.

24, the bevel gear 109 is fixed to the rotating shaft of the pulley 105, and the bevel gear 111 fixed to the rotating shaft 110, which is installed at a predetermined position and is rotationally driven by a motor (not shown) Across the toothed belt 112.

As a result, the pulley 105 is always rotated by the toothed belt 112 even when the pulley 105 is moved up and down, and the magazine roll 35 is rotated by the pressure of the traveling belt 4 against the magazine roll 35.

The above-described structure is to provide a necessary number of the belt 4 in a direction perpendicular to the traveling direction of the belt 4. [

The pressure of the compressed air injected into the air cylinder 108 is set so that the force that the belt 4 is brought into pressure contact with the magazine roll 35 is the force required for the first or second embodiment.

Further, in order to detect that the radius of the winding roll becomes large and the belt 4 is pressed a predetermined amount, the limit switch may be disposed below the belt 4 contacting the magazine roll 35 or the winding roll in this modification .

3. In the first to third embodiments, the air cylinders 26, 93, 94, 95, and 96 are used as the pressure contact members for pressing the belt 4 or 97, 98 as a traveling body against the magazine roll 35 However, instead of the air cylinder, it may be installed as follows.

For example, in Fig. 18 shown in the second embodiment, the support base 25 and the cylinder 26 are provided as shown in Fig. 25 and Fig.

116 are rotatably mounted on the lower side of the flat plate 28 so as to be opposed to the flat plates 28, and are supported so as to be rotatable by bearings 117, respectively. A lower end of the compression spring (118) is fixed to the upper end surface of each rotary valve (116), and the upper end of the compression spring (118) is brought into contact with the lower surface of the plate (28). A rotary shaft 119 is rotatably supported by a bearing (not shown) at a lower portion of the rotary valve 116 so as to be rotatable to a predetermined position and rotated and stopped by a servo motor (not shown) Are arranged over the entirety of sixteen belts (4) in a direction perpendicular to the traveling direction of the belt (4).

The cam 120 having the shape shown in Fig. 25 is disposed on the rotating shaft 119 at a position facing the flat plate 28 of the first group of belts 4 shown in the second embodiment, The cam 121 in the state in which the cam 120 is half rotated as shown in Fig. 26 is fixed to the position of the second group belt 4 relative to the flat plate 28, respectively.

In this state, in the first group, since the rotary valve 116 is lifted by the cam 120 and the compression spring 118 is reduced, a large force is applied to the flat plate 28, And is pressed against the magazine roll 35 with great force. On the other hand, in the second group, since the amount by which the rotary valve 116 is lifted by the cam 121 is small and the amount by which the compression spring 118 is contracted is small, a small force is applied to the flat plate 28 , The belt 4 is pressed against the magazine roll 35 with a small force. Further, the magnitude of the force obtained by the reduction of the compression spring 118 and the force obtained by extending from the reduced state can be appropriately determined by appropriately selecting the spring constant of the compression spring 118 and the shape of the cams 120 and 121 You can decide.

In the above-described configuration, when the belt 4 travels, for example, 500 mm, the servo motor is operated by a signal from a control device (not shown) to stop the rotation shaft 119 by half rotation. 26, the belt 4 is pressed against the magazine roll 35 with a small force because the compression spring 118 is extended as shown in FIG. 26, The cam 121 on the second group side is in the state of the cam 120 in Fig. 25 and the compression spring 118 is reduced, so that the belt 4 is pressed against the magazine roll 35 with great force.

Similarly, every time the belt 4 travels for 500 mm, the rotation shaft 119 is rotated halfway by a signal from the control device to stop the belt 4 of the first group and the second group, 35) can be alternately or in large portions.

The mechanism for using such a compression spring 118 is configured as follows as a modification example shown in FIGS. 23 and 24 described above.

27, the rotary valve 116, the bearing 117, the compression spring 118, the bearing (not shown), and the bearing (not shown) shown in Figs. 25 and 26 are used instead of the air cylinder 108 having the structure described in Fig. And a rotation shaft 119 and a cam 120 or 121, which can be rotated and stopped by a servo motor (not shown), are disposed.

As described above, the belt 4 to be used is divided into the first group and the second group, and the cams 120 or 121 are fixed in a state in which the cams 120 or 121 are turned counterclockwise relative to the belts 4 of the respective groups.

4. As described above, the air cylinders 26, 93, 94, 95, and 96 or the compression spring 118 that press the traveling body such as the belts 4, 97, and 98 with a predetermined force against the magazine roll 35 The force of the pressure contact member such as the combination of the cams 120 and 121 is alternately changed every time the travel distance of the belts 4, 97 and 98 becomes 500 mm. The travel distance is appropriately determined depending on the material, You can change it.

5. In the item 4, the force of the press-fitting member may be changed not only by the travel distance of the belts (4, 97, 98) but also by every predetermined time, for example every two seconds, by an operation signal from the control device.

6. In the first and second embodiments, the pressure of the air cylinders 26 of the respective groups is alternately changed by dividing the belts 4 into two groups. However, The pressure of the air cylinders 26 of only a proper number of the belts is changed to the first pressure or the second pressure and the pressure of the other air cylinders 26 is always equal to about one half of the first pressure .

7. In the first to third embodiments, the pressures of the air cylinders 26, 93, 94, 95, and 96 are set as described above as the first pressure for pressing the force of the pressing member, Material, thickness, and the like.

8. In the first to third embodiments and the modification shown above, the air cylinders 26, the compression springs 118 (for example, ), The pressure member being the first pressure is simultaneously changed to the second pressure and the pressure member which was the second pressure is changed to the first pressure which is higher than the first pressure. When leaving, the pressure may be changed as follows.

In other words, when the corresponding signal goes out, only the pressure member which has been the second pressure is switched to the first pressure, and once all the pressure-contact members are made to the first pressure, the pressure member, When the signal comes out from the signal transmitting member, at the same time, only the pressure member which has been at the second pressure at this time is changed to the first pressure, and once all the pressing members are set to the first pressure, The pressure member which has become the 1 pressure is changed to the second pressure, and the pressure is similarly changed as follows.

9. In the first to third embodiments and the modification shown above, the air cylinder 26, the compression spring (not shown), and the like, which are shown as an example of the signal transmitting member, 118), the pressure may be changed as follows.

That is, for example, the pressure of all the pressing members is set to the first pressure, and the pressure of all the pressing members is decreased or made to be zero for a predetermined time each time a signal is outputted from the signal transmitting member.

Even if the force of the pressure contact member is changed in this way, for example, the swollen portion 65a formed in the single-sheet pulling-and-winding shown in Fig. 15 is wound in a slightly loose state to become the winding roll 66.

Further, if the pressure of all the pressing members is reduced or made zero, the force for rotating the winding roll is reduced or zero and the rotational speed of the winding roll is lowered. Therefore, even if the rotational speed of the winding roll is decreased for the predetermined time, You can choose a time that you can perform a good pull and roll.

10. In the first embodiment, the force detected by the load cell 20 is such that the touch roll 6 is likely to be pressed against the magazine roll 35 or the winding roll 66 by a force of about 5 kilograms Value, but it may be appropriately changed depending on the material, thickness, etc. of the single plate.

11. In the first to third embodiments, when the detection signal of the load cell 20 or the limit switch 86 causes the magazine roll 35 to ascend or stop, ) Is continuously released for a time period of 1/4 of a rotation. This time may also be appropriately changed depending on the material, thickness,

12. In the first embodiment, although the load cell is shown as the force detector constituting the wound roll radius detecting member, any other device capable of detecting a force such as a rectifying type piezoelectric switch or the like may be used.

13. In the first embodiment, a male screw 38 or the like is used as a mechanism for moving the magazine roll 35 up and down. One end of the chain spanned across the sprocket is fixed to each support 51, The sprocket may be rotated and stopped by a motor to move up and down, and the magazine roll 35 may be moved up and down by the power of the air cylinder.

14. In the above embodiment, when the belts (4 or 97, 98) as the traveling body are brought into pressure contact with the magazine roll 35, the air cylinders (26, 93, 94, 95 and 96 or the cams 120 and 121 are rotated to change the force of the compression spring 118. Normally each belt is pressed against the magazine roll 35 or the winding roll 66 with the same force When the swollen portion 65a of the single plate is detected when the single plate is pulled and rolled as described above, the force at which the corresponding portion of the belt is pressed may be changed.

That is, the swollen portion 65a is formed at both ends in the direction immediately before the take-up roll 66 carry-in side and in the direction orthogonal to the single-plate run direction. For example, in the first embodiment, One limit switch 123 is disposed on each of upper and lower end belts 4 in the direction orthogonal to the direction in which the limit switches 123 are arranged, as shown in Fig.

The pressure of the air cylinder 26 of each belt 4 can be divided into first and second groups as in the first embodiment. Normally, each of the air cylinders 26 is a first embodiment The first pressure is set to the above-described pressure, and similarly, the single plate is pulled and wound on the magazine roll 35 in the same manner.

When the swollen portion 65a is generated on the outside of the first group side, the limit switch 123 at the corresponding position is turned on. The control device receiving the ON-state signal issues an operation signal to change the pressure of the first group air cylinder 26 to the second pressure in the first embodiment. Thus, the swollen portion 65a can pass between the take-up roll 66 and the touch roll 6 and is similarly wound to the take-up roll 66, and the swollen portion 65a disappears. As a result, the limit switch 123, which is in the ON state, is turned OFF, and the control device which receives the signal of the OFF state outputs an operation signal to set the pressure of the first group air cylinder 26, Pressure. The pressure of the second group side air cylinder 26 is changed as described above even when the swollen portion 65a occurs outside the second group side.

When the construction and control are performed as described above, it is effective when the type of wood or the thickness of the single plate is large, and the relatively swollen portion 65a is less likely to occur.

Further, the two limit switches 123 are provided as described above, and it is determined by the control device whether or not the limit switch 123 has been turned ON more than the number of times set at the appropriately set travel distance, The air cylinder 26 of the first group and the air cylinder 26 of the second group is automatically switched to the first pressure or the second group of air cylinders at predetermined travel distances as in the first embodiment, The second pressure may alternately be changed.

15. In the above embodiment, the magazine roll 35 is raised by the spacing changing member such as the male screw 38 when the winding of the single plate is pulled and wound on the magazine roll 35 and the radius of the winding roll is increased. As described below, the magazine roll 35 itself may not be moved up and down, but may be in a fixed position, and the traveling body may be lowered by the operating device.

As in the case of the second embodiment, only the belt 4 is described as an apparatus which is pressed against the magazine roll 35 or the winding roll.

The apparatus is configured as shown in Fig. 31, which is a diagram showing the direction of the arrow in the cross-section of one-dot-dashed line PP in Figs. 30 and 29, which is a diagram showing the direction of the arrow in the cross section of one-dot chain line NN in Figs. 29 and 29 .

And reference numeral 126 denotes a post placed on both outer sides of the belt 4 in a direction orthogonal to the running direction thereof.

Both ends of the shaft 127 are rotatably supported on the both struts 126 with bearings (not shown) therebetween so as to be rotatable about the shaft 127. Similarly, A rotary arm 129 that is a part of a holding member of the belt 4 is rotatably provided around the shaft 127 with a bearing 128 interposed therebetween .

Both ends of one shaft 131 are rotatably supported on the tip of the two rotary arms 129 via bearings 130 so that the pulleys 132 are spaced apart from each other by a distance of 16 Fix one. On the other hand, on the shaft 127, a pulley 133 is fixed at a position opposed to the pulley 132, and the belt 127 is passed across each of the opposed pulleys 132 and 133.

A pulley (not shown) across the belt 134 is fixed between the adjacent pulleys 133 on the shaft 127 so that the pulley 133 is supported on the outer end of the shaft 127, The belts 4 and 134 are caused to run in the direction of the arrow by rotating and rotating the rotation of the motor 136 on the fixed bevel gear 135 with the chain 137 interposed therebetween.

Between the rotary arms 129 on both sides in the direction of travel of the belt 4, both ends are fixed to the rotary arms 129 and rotate integrally with the rotary arms 129 And a support plate 138. 31, the upper end of the belt 4 in the running direction is supported on the support plate 138 below the respective belts 4 so as to be rotatable by the bearings 139, The air cylinder 141 is fixed on the support plate 138 under the lower side in the corresponding direction of the flat plate 140 so that the air cylinder 141 is pressurized with compressed air The tip end of the piston rod abuts against the bottom surface of the flat plate 140.

A limit switch (not shown) as a winding roll radius detecting member for detecting that the flat plate 140 is lowered by a predetermined amount is provided on the support plate 138 below the belt 4 at both ends in the direction perpendicular to the running direction of the belt 4 142, respectively.

30, air cylinders 143 are provided at the lower side of the two rotary arms 129 so that the tip of the piston rod 143a of the air cylinder 143 and the lower end of the rotary arm 129 The pin 144 is connected to the latching portion. The size of the air cylinder 143 and the compressed air pressure in the initial state to be injected into the air cylinder 143 are set such that the compressed air is supplied to the air cylinder 143 When the compressed air is injected, the piston rod 143a is advanced to the stroke end, and sets the respective values such that the rotary arm 129 is supported almost horizontally as shown in FIG. Further, after the compressed air of the set pressure is injected, the compressed air injection port of the air cylinder 143 is closed, and the compressed air of the air cylinder 143 thereafter is sent to the control device 142 which receives the detection signal from the limit switch 142 (Not shown), as will be described later.

The sixteen belts 4 are divided into first and second groups and the pressure of the air cylinders 141 of each group is controlled by the operating signal from a control device The operation of alternately changing to the first pressure or the second pressure is the same as that of the second embodiment.

On the other hand, the magazine roll 35 capable of being driven rotatably is in a fixed position without lifting up and down as in the second embodiment when the single plate is pulled and wound, and the nozzle 31 for moving the yarn as in the second embodiment to supply the yarn Respectively.

As a modification of the present embodiment, the belt 4 and the single roll are continuously conveyed by the belts 134 and 4, and the roll is wound around the magazine roll 35 together with the yarn to form a winding roll. As in the second embodiment, 1 pressure or the second pressure, the same effect can be obtained.

When the pulling winding is further advanced and the radius of the winding roll wound on the magazine roll 35 is gradually increased, the pressing force of the winding roll on the belt 4 is gradually increased. However, the position of the magazine roll 35 in the vertical direction is not changed, Only the belt 4 and the flat plate 140 are pushed downward from the state of Fig. 31 and the flat plate 140 is pressed against the support plate 138 by the air cylinder 143, The gap between the flat plate 140 and the support plate 138 is narrowed. The limit switch 142 is disposed on the support plate 138 as described above so that when the flat plate 140 rotating downward comes into contact with the limit switch 142 and the limit switch 142 is turned on, A signal is transmitted to the control device.

An exhaust valve of the air cylinder 143 is opened by an operation signal from the control device which receives the signal, and the compressed air injected in the initial state is discharged to the atmosphere. Thus, the force of the air cylinder 143 supporting the rotary arm 129 is reduced, the piston rod 143a is retracted into the air cylinder 143, and the rotary arm 129 rotates downward. The distance between the support plate 138 and the winding roll is widened by the lowering and the flat plate 140 is constantly subjected to an upward force by the air cylinder 141, The distance between the flat plate 140 and the support plate 138 is widened so that the limit switch 142 is moved away from the flat plate 140. As a result, As a result, when the limit switch 142 is turned OFF and this signal is transmitted to the control device, the control device issues an operation signal to close the exhaust valve that the air cylinder 143 was opening. Thereupon, the retraction of the piston rod 143a into the air cylinder 143 is stopped, and the rotational movement of the rotary arm 129 is also stopped, so that the piston rod 143a is supported by the air cylinder 143 in a state of being slightly inclined from the horizontal state , The belt 4 is brought into pressure contact with the take-up roll as described above and the pulling and winding of the end plate is continued.

Thereafter, the exhaust valve of the air cylinder 143 is opened and closed so that the rotary arm 129 is slightly lowered and rotated by a certain amount each time the limit switch 142 is turned ON, The exercise is to pull and wind.

16. In the above description, the load cell 20, the limit switch 86, the limit switches 99, 100, and the limit switch 142 are used for detecting the radius of the take-up roll, Or a photoelectric switch comprising a plurality of light emitters and light receivers arranged in a row, and the yaw may be any as long as it can detect the radius of the winding roll.

17. In the first and second embodiments described above, the touch roll 6 is configured to be driven to rotate by the magazine roll 35 or the take-up roll 66. However, depending on the wood type of the end plate, The circumferential speed of the take-up roll 66 may become smaller than the speed of the belt 4 due to the resistance for rotating the belt. On the other hand, since the end plate is conveyed at the speed of the belt 4 by the belt 4, the end plate is loosened at the carry-in side of the take-up roll 66,

Thus, although not shown, if the touch roll 6 is driven and rotated by a driving source such as a motor in the same direction as the belt 4 and at a peripheral speed slightly higher than the speed of the belt 4, The resistance for rotating the touch roll 6 by the winding roll 66 is eliminated, and the above relaxation does not occur.

18. In the above description, the end plate is wound around the magazine roll 35 to detect the radius of the winding roll, and the intervals between the magazine rolls 35 and all the traveling bodies are changed by the interval changing member 17 and 18. In the second embodiment described with reference to Figs. 17 and 18, by using the long air cylinder 26 of the piston rod, the interval changing member is not necessarily provided, The pulling of the single plate may be performed in response to the increase in the radius of the single plate.

19. It is assumed in the above description that the bearing 33 is not likely to fall upward from the support portion 52 even if the magazine roll 35 is subjected to an upward force from the belt 4 and the touch roll 6 The bearing 33 is placed on the support portion 52 of the supporter 51 and then the bearing 33 is sandwiched between the supporter 52 and the upper portion of the bearing 33 The sacrificial roll 35 may be fixed to the holding base 51 by bolts.

As described above, according to the present invention described in Claims 1 to 15, since the end plate is wound well without being deviated from the course and rarely wound in the overlapped state, the yield at the time of pulling and winding is improved and the quality is also improved .

The invention described in the following claims also has the following effects.
