Description

[Detailed description of the invention] (a) Technical field The present invention is a pinwheel type multi-stage texture correction that simultaneously corrects the grain of multiple pieces of cloth such as towels, that is, corrects the diagonal distortion of the weft grains of each running cloth at the same time. Regarding machines.

(b) Prior Art and Purpose of the Invention To straighten the grain of a towel, it was believed that towels, unlike knitwear, did not necessarily require precise grain straightening, so the towel was stretched by pulling both ends of the towel by hand. Conventionally, this was done using an extremely irrational and crude method, but it naturally causes considerable variation in the finished state of grain straightening, and at the same time causes a decline in quality. It's becoming difficult to deal with.

On the other hand, as seen in, for example, Japanese Utility Model Application Publication No. 55-015056, a grain straightening machine using a pin wheel has a pair of pins spread out along the edges of both sides of the running cloth in the width direction of the cloth. The wheels are arranged, and while pins protruding from the outer periphery of the pin wheels are used to sequentially pin both side edge ends of the cloth, the diagonal strain of the weft grain in the cloth is measured by the difference in rotational speed between the two pin wheels. In other words, there is already known a grain straightening machine that corrects the grain by using a difference in the overfeed rate of the cloth.

Furthermore, as a significantly improved mechanism for operating the pinwheel, Japanese Utility Model Application Publication No. 58-004700 discloses a system in which the edges of both sides of the running cloth are connected to a group of pins protruding from the outer periphery of the pinwheel. A pair of pinwheels for pinning, a pair of pinwheel stands that support each pinwheel in a tiltable manner about a tangent line or a line in the vicinity of the pinning start position of the outer periphery of the pinwheels, and are movable in the cloth width direction; A grain straightening machine is disclosed that includes an inclination angle adjusting means for adjusting the inclination angle of a pinwheel to a desired degree of divergence, and a position adjusting means for adjusting each pinwheel stand to a desired position in the cloth width direction.

In the case of this weave straightener, no matter how the inclination angle of each pinwheel is adjusted, the pinning start position of the pinwheel outer periphery through which the swing centerline passes or adjacent thereto is practically almost not displaced, so there is no need for adjustment of cloth rehanging or position adjustment of brush rolls and other auxiliary devices accompanying adjustment of the inclination angle of each pinwheel. Furthermore, this weave straightener has a position adjustment means for adjusting each pinwheel base to a required position in the cloth width direction, for example, a mechanism for screwing each pinwheel base to a feed screw shaft bridging in the cloth width direction and rotating the feed screw shaft forward and backward to move each pinwheel to a required position in the cloth width direction, so that it is easy to adjust the distance between both pinwheels according to the width of the cloth to be processed and to introduce a system for automatically making the pinwheel follow the edge of the running cloth.

An object of the present invention is to provide a multi-stage texture straightening machine that can straighten multiple pieces of cloth such as towels at the same time.

Another object of the present invention is to provide a multi-stage grain straightening machine that occupies a small floor area per processing capacity, is easy to manage, and can shorten the distance to subsequent devices.

(c) Structure and operation of the invention In order to achieve the above objectives, the invention has the following features:
A pair of pin wheels that pin the edges of both sides of the running cloth using a group of pins protruding from the outer periphery of the pin wheel. A pair of pinwheel stands tiltably supported at the center and movable in the fabric width direction, an inclination angle adjusting means for adjusting the inclination angle of each pinwheel to a required degree of distal spread, and a pinwheel stand configured to adjust each pinwheel stand as required in the fabric width direction. Grain straightening machines each having at least a position adjustment means for adjusting the position of the grain straightening machines are arranged in the upper and lower rows so that the cloth width direction of each grain straightening machine is aligned, and the cloth applied to each grain straightening machine is prevented from overlapping or intersecting. A multi-stage texture straightening machine is disclosed in which each pinwheel in each texture straightening machine is arranged.

In the above, there is no particular restriction on the pinwheel support mechanism using the pinwheel stand or the pinwheel inclination angle adjusting means. For example, each pinwheel is rotatably connected via an arm or the like to a variable-angle shaft located on a tangent to the pinwheel's outer periphery or a line in the vicinity thereof, and the variable-angle shaft is rotatably connected to a pinwheel base. A worm wheel is attached to the variable angle shaft, and the worm wheel is engaged with a worm rotatably mounted on a pin wheel base. It is possible to adopt a configuration in which the pin wheels are cross-linked in the width direction, and by adjusting the rotation angle of the worm shaft, the inclination angle of each pin wheel can be adjusted to a desired degree of divergence.

Furthermore, in the present invention, each pinwheel whose inclination angle has been adjusted is pressurized in the direction of increasing its inclination angle by the elasticity of the spring mechanism, so that while the running cloth is being pinned by each pinwheel, When the fabric is subjected to abnormal tension in the width direction,
In order to relieve the tension, each pin wheel is deformed by a required amount in the direction of reducing its inclination angle, thereby preventing the cloth from deforming or breaking. For example, in the configuration in which the worm wheel and worm are engaged with each other, the worm is mounted on a pin wheel stand via a spring mechanism, such as a compression coil spring, arranged adjacent to the worm on its axis, and each pin wheel is connected to its It may be configured to apply pressure indirectly in the direction of increasing the inclination angle. Further, the inclination angle of each pinwheel in the present invention may be adjusted using a manual rotating handle, or by manually or automatically operating a motor or other prime mover. In this case, the worm shaft, which rotates in conjunction with the worm, can be rotated to adjust the desired rotation angle.In this case, by rotating the worm shaft forward and backward, each pinwheel can be equally changed in opposite directions. If the pin wheels are tilted by an angular amount, each pinwheel can always be tilted symmetrically with respect to the running center line of the cloth.

In addition to the above-mentioned screw feeding method, the means for adjusting the position of the pinwheel base includes, for example, mounting an actuator on each pinwheel base and moving each pinwheel base in the cloth width direction using the driving force of the actuator. A configuration like this can be adopted. In the above, the actuator refers to a motor or other device that generates a mechanical motive force, and a mechanism that converts the mechanical movement of such an actuator into movement in the cloth width direction of each pinwheel base is appropriately selected and the position is adjusted. What is necessary is just to constitute an adjustment means. For example, a motor is mounted on each pin wheel base, and a pinion rotated by the motor is meshed with a cross-linked rack in the cloth width direction, or a nut rotated by the motor is connected to the cloth width direction. It is constructed by screwing together with a screw shaft bridged in the direction, and each pinwheel stand, and therefore each pinwheel, can be moved to a desired position in the cloth width direction by a control signal to the motor. . If the actuators mounted on each are used as the position adjustment means of the pinwheel base as in the latter case, it is possible to downsize the device, and it is possible to select the running center position of the cloth in the width direction of the cloth and the distance between both pinwheels. can be adjusted more freely, therefore, it has excellent adaptability to cloth widths and the cloth widths vary widely. Multi-stage texture straightening of two or more types of fabrics can also be configured to be able to be processed in a versatile manner by appropriately selecting and adjusting the running center position of the fabric and the spacing between both pin wheels in each texture straightening machine. be.

When constructing a multi-stage cloth straightening machine by combining a plurality of unit grain straightening machines having the above configuration, each grain straightening machine should be installed in parallel in the upper and lower rows so that the width direction of the cloth is aligned, and the upper and lower rows should be arranged interchangeably. It is only necessary to arrange the pin wheels of each cloth straightening machine so that the cloth hung on each cloth straightening machine adjacent to each other or adjacent to each other on the same stage does not overlap or intersect with each other. When processing 3 bath towels, place 3 machines on the top shelf and 3 machines on the bottom shelf alternately, and when processing 3 bath towels, place 1 machine on the top shelf and 2 machines on the bottom shelf alternately. suitable.

In addition, the inclination angle adjustment means of each pin wheel in each unit grain straightening machine of each stage or all of the upper and lower stages are linked, and the inclination angle of all pin wheels in the upper stage and/or lower stage can be adjusted at once with one operation. It may be possible to do so. For example, when using a worm shaft as described above, the unit grain straightening machines in the upper and lower stages should each have a common worm shaft, and if necessary, the upper and lower worm shafts should be connected to a gear mechanism, etc. They can be linked to each other via.

Next, the present invention will be explained in more detail based on the drawings. Fig. 1 is a side view of the main part of a specific example of a unit grain straightening machine that can be used in the present invention, Fig. 2 is a front view of the main part of the pinwheel operating mechanism part in Fig. - This is a line sectional view, and firstly, the pinwheel mechanism will be mainly explained. Two guide shafts 1, 2, a worm shaft 3, and a rack 4 are arranged in parallel in the cloth width direction by bridging the left and right frames 5, 5. A pair of pin wheel stands 6, 6 are slidably fitted into the two guide shafts 1, 2. Since the pair of pinwheel stands 6 and 6 have the same pinwheel mechanism, the pinwheel mechanism in one pinwheel stand will be explained below. 7
is rotatably mounted on a shaft in a direction perpendicular or substantially perpendicular to the cloth width direction via a bearing (not shown), and a worm wheel 8 is disposed in the middle of the angle-changing shaft 7.
are on the same axis, and a fork-shaped arm 9 is attached diagonally downward at the tip thereof. A pinwheel 10 is pivotally attached to the arm 9 in such a manner that the extended axis of the angle-changing shaft 7 is a tangent to the pinwheel outer circumference at the pinning start position P or a line near the tangent to the pinwheel outer circumference. A large number of pins 11 are protruded at required pitches.

In addition, a worm 12 is mounted on the pin wheel stand 6.
It is rotatable while being engaged with the worm wheel 8, and is installed in the cloth width direction via a compression coil spring 13 arranged in series on the outside thereof, and is slidable in the axial direction with the worm shaft 3 and interlocked around the axis. It is rotatably fitted onto the worm shaft 3.
Furthermore, an adjustment bolt 14 is attached to the pin wheel base 6.
is screwed loosely through the worm shaft 3 so as to press the outer end of the compression coil spring 13 via the bearing 15. The worm shaft 3 is connected at its end to a manual rotation handle, a motor, or other rotational drive mechanism (not shown) for adjusting the tilt angle, and its rotation angle is adjusted.

Further, the pin wheel base 6 includes a position adjustment motor 16, its transmission section 17, and a pinion 18 that is rotationally driven by the position adjustment motor 16.
is mounted, and its pinion 18 is meshed with the rack 4.

In the configuration of the pinwheel mechanism as described above, by adjusting the rotation angle of the worm shaft 3, the degree of spreading, that is, the inclination angle of the pinwheel is adjusted. That is, the rotation of the worm shaft 3 is transmitted to the worm 12, the worm wheel 8, and the angle-changing shaft 7, and the swinging of the arm 9 and, therefore, the pin wheel 10.
causes the left and right pin wheels 10, 1 to swing.
0 are tilted in opposite directions by the same amount of displacement. In that case, the inclination angle of the pinwheel 10 may be detected by a potentiometer, and such a detection potentiometer and an angle setting potentiometer may be connected in parallel, and the inclination angle between them may be A mechanism may be adopted in which the motor and other rotary drive mechanisms for adjusting the inclination angle are automatically operated in order to reduce the output deviation to zero, and the worm shaft 3 is rotated by the required amount in the required direction. Furthermore, when the cloth stops running during pinning by the pinwheel 10, the pinwheel inclination angle is immediately adjusted to protect the cloth from being locally exposed to a long-term spreading action. It may be reduced, preferably to 0 degrees. When the cloth is subjected to abnormal tension in the cloth width direction when pinning the cloth with the pinwheel 10, the compression coil spring 13 is compressed and the inclination angle of the pinwheel is reduced, so that the cloth is protected from damage or breakage. protected. The elasticity of the compression coil spring 13 can be adjusted depending on the allowable tension of the fabric and other factors, and this is done by turning the adjustment bolt 13. In addition, as a means to maintain the tension in the cloth width direction of the cloth within a predetermined range with high precision, for example, it is possible to directly or indirectly detect the tension in the cloth width direction of the cloth and at the same time set the deviation from the set tension to 0. A mechanism that automatically rotates the worm shaft 3 can be adopted.

In addition, in the configuration of the pin wheel mechanism as described above, when the position adjustment motor 16 mounted on the pin wheel base 6 is started, the pinion 18 is rotationally driven via the transmission section 17 and the rack 4 is brought into the meshed state. Since it moves in a straight line, the pinwheel stand 6
The rack itself also moves linearly on the rack 4, and by controlling the motor 16 for adjusting its position, each pinwheel 10 can be freely moved in the cloth width direction, and both pinwheels 10, 10 It is possible to easily adjust the interval between the pin wheels, select the running center position of the cloth in the width direction of the cloth, and even introduce a system that automatically causes the pinwheel 10 to follow the edge of the running cloth.

Next, the overall structure including the pinwheel mechanism as described above in a specific example of the present invention will be explained. 24, 24, brush rolls 25, 25, pin wheels 10, 10, bar expander 26, etc., and are supplied to, for example, an endless belt (not shown) of an autoscreen textile printing apparatus.

In the above configuration, the centering roll 19
corrects the running of the cloth C, and the edge sensor 20 detects the edge of the cloth C for the running correction. The feed rolls 21 and 22 run the cloth C by a motor (not shown), and the dancer roll 2
3 is a pinwheel 10 that swings in accordance with the difference between the amount of cloth C fed by the feed rolls 21 and 22 and the amount of cloth C pulled out by the endless belt (not shown), so that the cloth C is always kept at a low tension. ,10
supply to. The brush rolls 25, 25 push the cloth C into the outer periphery of the pin wheels 10, 10 in an overfeed state, and the pin wheels 10, 10 automatically follow the edge of the running cloth C while pushing the cloth C into the pushed cloth C. The cloth C is pinned in an overfeed state and the grain is corrected, and the edge end sensors 24 detect the edge ends of the cloth C for automatic tracking. Further, the bar expander 26 expands the cloth C after grain correction in order to supply the expanded cloth C to a subsequent endless belt (not shown).
