Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a paper pile device that performs a napping action on a fabric using a paper roller coated with emery paper◎ (Prior art) Conventional 1 Counter pile rollers and pile rollers are arranged alternately so that the cloth is circumscribed by each roller at a predetermined angle, forming a group of four napping rollers,
There is a napping test machine or a napping device that is provided with a cloth feeding device before and after the group of napping rollers, and a cloth guiding device having a group of guide marches and at least one gauge below the group of napping rollers (for example, Japanese Patent Publication No. 59-217
71, Japanese Patent Publication No. 58-70776).

In the above device, remove the 1 counter pile roller and the nap roller of the pile roller, increase the diameter of one of the above rollers, wrap an abrasive cloth on the surface of the P-2, and apply it to the action of the paper nap machine. Approximate effects are performed.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional technology, the gauge for adjusting the contact angle of the cloth in contact with the paper roller is disposed in a cloth guide device provided separately from the main body. Therefore, it is difficult to maintain parallelism between the paper roller and the gauge. In addition, when the position of the gauge is moved to adjust the contact angle, the contact angle between the fabric and the capstan roller in the back tensioning device or cloth feeding device changes, and as a result, the contact angle of the fabric with the capstan roller changes. The disadvantage is that the tension varies.

However, since the napped action is performed below the paper roller, the surface of the napped cloth comes into direct contact with the capstan roller and the cloth is fed out, resulting in the disadvantage that the napped fibers are cut.

In addition, since the cloth is passed downward, it is not possible to have a large contact angle between the back tension roller or the capstan roller and the cloth, and the frictional force between the cloth and the above-mentioned Q is small and it is difficult to maintain sufficient tension on the cloth. unable to give.

Also, when piecing together thick cloth to create a nap effect,
There was a drawback that the seam of the cloth was a pinch roller and the tension of the pack fluctuated, causing a raised effect ≦ l/A. (Means for solving the problem) The present invention uses emery paper. Two coated paper rollers are arranged in parallel, a cloth feeding device and a pack tensilon device are provided before and after the above-mentioned pH roller, and a guide roller is provided approximately at the middle upper part of the above-mentioned two paper rollers. Furthermore, by providing an adjustable roller swingably above each of the above-mentioned paper loaches, the cloth passes over the paper rollers, and the contact angle between the cloth and the paper rollers is further adjusted. It was configured as follows.

Further, since a buffer is provided in the pinch roach of the fabric feeding device and the back tensioning device, the pinch roach can be prevented from jumping up at the seam of the fabric even when raising thick cloth.

(Embodiment) Fig. 1 shows an embodiment of the present invention, in which numeral 1 is a control box containing a control circuit for an electrical system, and a speedometer, pushbutton switches, etc. are installed on the surface.

Reference numeral 2 denotes a lid making body that has a built-in mechanical system, and a group of various rollers and the like that are driven in conjunction with this built-in mechanical device are arranged on one side of the snow making body 2. That is, 3 is a paper roller whose surface is coated with emery paper 4, two of which are arranged in parallel at a required interval. The paper roller 3 has a bare diameter of 1241 mm, and when covered with one emery paper 4, the outer diameter becomes about 1251 mm. The two paper rollers 3 are each driven at variable speed by a toothed belt from a separate variable speed motor via a powder clutch. 5 is a capstan roller (outside diameter φ93
The surface is covered with sponge rubber having a hardness of about H8C600 and a thickness of about 10 mm, and is driven by a motor at variable speed.

7 is a tension binding roller that applies tension to the cloth, and the surface has a hardness of about HsO60' and a thickness of about 1
It is covered with sponge rubber having zero elasticity and is connected to the powder brake via a toothed belt.

Reference numeral 6 denotes a pinch roller, which is a steel roller with a smooth surface and an outer diameter of 70 mm, and is configured to press against the capstan roach 5 and the back tension swirler 7, respectively.

In addition, the surface is not limited to a smooth surface, and it is also possible to coat it with butylene sponge rubber with a hardness of about H11a2O2 to a thickness of about 10 mm.In other words, the pinch roller 6 can be attached to the swing arm 11 as shown in Fig. 2. It is pivoted. The swinging arm 11 is swingably provided at one end of a shaft 10 which is supported by bearings 9 respectively attached to bearing plates 8, 8 fixed to the machine frame. The end of the swing arm 11 is pulled downward by a tension spring and pressed against the capstan roller 5 and the back tension roller 7. For this reason, the cloth is pressed against the capstan roller 5 or the back tension run roller 7, and the frictional force between the cloth and the capstan roller 5 or the back tension run roller 7 is increased.

In the above embodiment, a tension spring is used, but it is also possible to use a heavy pinch roller and use its own weight to press the cloth.

Further, as shown in No. 21NK, a detachment handle 12 for separating the pinch roller 6 from the capstan roller 5 or the back tension roller 7 is attached to one end of the swing arm 11 provided with the pinch roller 6. When the pinch roller 6 is pulled outward (in the direction of the arrow), the pinch roller 6 is pulled upward against the tension spring or its own weight.1 As shown in Fig. 1, the pinch roller 6 and the capstan roller 5 or about 20 W between back tension roller 7
This creates a gap of 8 degrees.

When the handle 12 is pulled, the handle is automatically caught on a cam 13 provided on the machine frame, and the gap is maintained. One end of the cam 13 is rotatably supported by the machine frame, and the other end is provided with a notch into which a handle lock is engaged.

Further, as shown in FIG. 2, a bracket 14 is fixed to the bearing plate 8 above the swing arm 11.
A shock absorber 15 is attached to the bracket 14. When the tip of the spindle 16 of the shock absorber 15 comes into contact with the protrusion 17 provided on the swing arm H and the pinch roller tries to jump up suddenly, the shock absorber 15 acts as a resistance, causing the pinch roller to move upward. 6 to prevent it from jumping upwards. For this reason, even if a thick cloth seam passes between the pinch roller 6 and the capstan roller 5 or the rose/cut tension roller 7, the pinch roller 6 will not jump up. Effect: Prevents unevenness from occurring.

Next, 18 is a capstan auxiliary roller with a smooth surface and an outer diameter of φ70.
019, which rotates in the opposite direction at 5 speeds, 2 to 5% higher than the surface speed, is an anchor roller that prevents the edges of the fabric from rolling up.It has an outermost diameter of φ701m+ and has a spiral groove on the surface. is provided. The rotating direction is opposite to that of the capstan auxiliary roller 18 at about 1100 rpm. The spiral groove has two threads with a pitch of 15 and a lead 301, with a left-hand thread on the main body side and a right-hand thread from the center. 20 is a guide bar, which guides the cloth. Further, 21 is a winding detection guide bar, which is designed to swing up and down about the guide shaft 22. Note that a weak tension is applied to the cloth due to its own weight. Moreover, above the base of the detection guide bar 21 with nine windings,
A limit switch is installed, and when the winding detection guide bar 21 rises above a predetermined position, it kicks the actuator of the limit switch, outputs a contact signal, and outputs all powder clutches, powder brakes, and motors. There is no way to stop it. That is, if the endless cloth wraps around the roller, etc., the device will automatically stop and
can be avoided from damage. Wrapping detection guide bar 21
The stroke is approximately 150all, and the limit switch is turned on when the winding detection guide bar 21 comes to a position approximately 70fi from the bottom end of the stroke (corresponding to 50t downward from the line connecting the two guide bars 20). .

Reference numeral 4 denotes a guide shaft, which is used to pass through the cloth as shown in B when the anchor roller 19 is applied to the cloth as shown in FIG. Note that when the anchor roller 19 is not activated, the cloth is passed through as shown in the third mG.

In addition, in Fig. 3, the paper roller of this embodiment is replaced with a cloth roller covered with cloth, and two cloth loaches are added between the cloth rollers, and the paper roller is replaced with a cloth roller covered with cloth. The method of threading the cloth in a case where the device is changed to cause a nap effect is shown below, but it is basically the same as the method of threading the cloth in this embodiment.

Therefore, the drawings regarding how to thread the cloth in this embodiment are omitted.

Next, the blade is a cloth stretch absorption guide and is attached to the slider 24. This slider is movably arranged on a slide rail 5 provided on the side of the machine. When the cloth stretches as a result, by moving the slider U outward, the slack caused by the stretching of the cloth is absorbed. Also, there is a guide ring, which adjusts its position so that the endless cloth is approximately in the center of the roller.

n is a guide roller with a smooth surface and an outer diameter of φ60, and is rotatably arranged above the middle of the paper roller 3. 4 are contact angle adjustment guide rollers, which are provided above the paper roller 3 so as to be freely rotatable and swingable. The contact angle adjusting guide roller has an outer diameter of φ5Qxm and a smooth surface.

Further, as shown in FIG. 4, the contact angle adjustment guide roller path is rotatably supported by one end of the contact angle adjustment swing arm 29. Further, the contact angle adjustment swing arm 29 is fixed to one end of a shaft shaft supported by a bearing 9 attached to the inside of a bearing plate 8 provided on the machine frame. Further, one end of one swinging rod 31 is fixed to the middle of the shaft 30.

A two-part notch is provided at the other end of the swinging rod 31, and a cylindrical swinging pin 32 having a female thread in the center passes through this notch and is rotatable. is inserted into. A male threaded portion provided at one end of the contact angle adjusting screw is screwed into the female threaded portion of the swinging pin 32, and the adjusting screw wing is rotatably supported by a bearing 9 disposed on the machine frame. . A handle 34 is provided at the other end of the contact angle adjusting screw.

Now, when the handle is rotated, the contact angle adjustment guide roller swings vertically about the shaft 30. When the contact angle adjustment guide roller 4 moves up and down, the contact angle of the cloth to the paper row 7-3 changes steplessly from a non-contact state to about 6oO. If the contact angle is increased, the paper will act more strongly.

In addition, in FIG. 2, the pinch roller-swinging arm 11
A limit switch (tf in the figure) is arranged so that the actuator comes into contact with the protrusion 17 formed in It is decided that he will come out.

When the contact output of this limit switch is output, the circuit in the control system is configured so that the 1% output, etc. is not output.
If the cloth is passed through the capstan roller 5 while the pinch roller 6 is separated from the capstan roller 5, the cloth will wrap around the capstan roller 5 and the operation will become impossible. Since the capstan roller 5 is configured not to rotate in this state, such an accident can be prevented. Similarly, in the case of a pack tension binding device, it is not necessary to forget to apply tension to each piece of fabric, and a stable raised state can be obtained.

The capstan roller 5 is driven by a variable speed motor via a speed reducer and a toothed belt. It is possible to change the speed within the range of orpm.

In addition, in this embodiment, in order to also perform the napping action by the clothing roller, the capstan roller is configured to be driven by a separate motor and speed reducer.
Capstan auxiliary ruler 18 is connected to capstan roller 5 by a gear, and capstan roller 50
It rotates in the direction of cloth travel at 5th speed, which is a few percent faster than 5th speed.

Next, the paper roller system consists of two sets of four shafts, including the shaft for the clothing roller, and is approximately φ8
It is arranged so as to be convex upward at a position that evenly divides the circumference of 04.4. Each of the four shafts alternates with two
Each pair is connected by a toothed belt, and each is driven by a variable speed motor via a powder clutch 1 speed reducer. In the case of paper pile raising, only the outer two rollers are used as paper rollers. In the case of napping using a cloth roller, remove the paper roller and insert the cloth roller into the four shafts.

The rotation speed of each shaft can be changed from 80 to 25 rpm. The back tension roller 7 is connected to a powder brake via a toothed belt. It cannot rotate by itself, but is dragged around by cloth.

The anchor roller 19 is driven by a motor through a toothed belt, and moves 1 in a direction opposite to the traveling direction of 1 cloth.
Except for the anchor roller and capstan auxiliary roller, which rotate at a constant speed of about 0θrpm, the speeds of all other drive rollers are digitally displayed on the control panel.

The speed range of the capstan roller 5 and the rotation direction of the paper roller 3 can be changed using a changeover switch on the control panel, and the rotation speed of each roller can be set by turning the polygon 1 on the control panel. conduct.

The excitation current for the powder clutch and powder brake is adjusted using the slider on the control panel.

Note that the capstan roller 5 can also be rotated in the opposite direction and inched using a push button switch on the panel.

(Effects of the Invention) In the present invention, since the fine parallelism between a part of the contact angle adjustment guide roller and the paper roller 3 is sufficiently ensured, the parallelism does not change even when the contact angle is changed, and the roller Uniform hair raising action can be performed over the length direction.

In addition, since the cloth is configured to pass above the paper roller 3, the contact angle of the cloth in contact with the capstan roller 5 or the back tensile roller 7 can be made sufficiently large. Even if the contact angle between the paper roller 3 and the cloth changes due to the movement of the adjustment guide roller 4, the contact angle between the capstan roller 5, the back tension roller 7 and the cloth does not change. Therefore, feeding the cloth,
Alternatively, the back tension applied to the cloth remains stable without fluctuations, so that uniform raising action can be performed at any time.

Further, in the present invention, since the cloth is passed above the paper roller 3, the surface of the cloth subjected to the napped action does not come into direct contact with the surface of the capstan roller 5 or the back tensile silane roller 7, and the napped The surface properties will not deteriorate.

Further, since a wrapping detection guide bar is provided, it has many excellent effects such as being able to prevent damage to the device due to wrapping of the cloth roller 7.
