Abstract

PURPOSE: To provide a table structure enabling the obtaining of various kinds of uneven patterns by the displacement of a table, or protrusions or recesses as if many tables were used in spite that only one table is used. CONSTITUTION: A pile woven fabric is transferred on a long sized table and, during the transfer, the tips of the piles of the transferred fabric are evenly cut off by the shearing action generated between a spiral cutter placed upper side and a lower blade. In this shearing apparatus, protrusions and recesses for creating uneven patterns on pile fabric cloth are formed on the table 4. Further, the shearing apparatus is provided with a drive-controlling means for displacing the whole table, or at least either of the protrusions or recesses during the transfer of the fabric. A preferable mode is that protrusions 4b are integrally formed on the outer peripheral surface of a tubular main body 4a of the table 4. The whole table is appropriately moved in a reciprocal manner by a reciprocal motion-driving means 6. The other preferable mode is that recesses are formed with plural protruding finger members placed in such a manner as to be movable in a longitudinal direction on the base materials of the table and the finger members are each appropriately moved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to a pile surface of a pile fabric,
The present invention relates to a table structure of a shirring device that reveals various uneven patterns.

[0002]

2. Description of the Related Art A shirring device is constructed so that a pile fabric is conveyed onto a table and the pile is cut and aligned by the shearing action of a spiral cutter and a lower blade arranged above the table. Therefore, in order to show the uneven pattern on the pile surface of the pile fabric, the unevenness is formed on the upper surface of the table to give a shearing action to the pile in the height direction, and the pile portion corresponding to the convex portion is formed. The reason is that it can be cut short.

For this reason, as the table, a long and substantially prismatic main body having irregularities formed on the upper end edge thereof, or the outer peripheral surface of the main body consisting of a rotating roll rotating in synchronization with the conveyance of the pile fabric, Some have irregularities.

However, with these table structures, the uneven patterns appearing on the pile fabric are monotonous corresponding to the unevenness of the table, and only one kind of uneven pattern can be obtained from one table. The former table having a substantially prismatic main body has the same unevenness pattern from the beginning to the end, and the latter table having a rotating roll-shaped main body has repeated unevenness at intervals according to the length of the outer peripheral surface. It is a pattern.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a shirring device is provided which, by appropriately driving a table when a pile fabric is conveyed, can obtain various uneven patterns from one table at low cost. The purpose is to provide a table structure for.

[0006]

[Means for Solving the Problems] A means for solving the above problems is to convey a pile fabric on a long table,
A shearing device for mowing and aligning pile tips of a pile fabric by a shearing action of a spiral cutter arranged above and a lower blade at the time of the conveyance, wherein an uneven portion for showing an uneven pattern on the pile fabric is provided on the table. And a drive control means for displacing at least one of the entire table and the concavo-convex portion when the pile fabric is conveyed.

Specifically, for example, referring to FIG. 3 of the embodiment, the drive control means may be composed of a reciprocating means 6 which reciprocates the table 4 along the length thereof as appropriate. .

Further, for example, referring to FIG. 11 of the embodiment, a plurality of fingers in which the concavo-convex portion of the table 11 is projected on the long table base material 12 so as to be movable along the length direction thereof. .. and the drive control means may be composed of moving means 16 for appropriately moving the finger members 13.

Further, referring to FIG. 15 of the embodiment, the table 31 is formed in a roll shape which rotates in synchronization with the conveyance of the pile fabric, and the drive control means controls the rotation of the table 31. The rotation control means 32 for blocking at an appropriate position may be used.

[0010]

According to the structure of the present invention, when the pile fabric is conveyed, the entire table supporting the pile fabric or only the uneven portion is appropriately displaced by the drive control means, for example, in the longitudinal direction or the vertical direction of the table. To do. When this displacement occurs, the position of the convex part shifts, and the part that is short is
The table is displaced to a position that is not normally located.

When the drive control means is not driven, a predetermined uneven pattern corresponding to the type of table appears.

According to the second aspect of the invention, every time when the reciprocating means as the drive control means is actuated and the table is moved along its length, the uneven portions of the table are displaced while maintaining the same interval. However, a parallel uneven pattern is obtained.

According to the third aspect of the present invention, when the moving means as the drive control means is activated, the finger members forming the convex portions of the table move under predetermined conditions, and the finger members are not limited to being parallel, but can be varied. An uneven pattern is obtained.

According to the structure of claim 4, when the rotation control means, which is the drive control means, is activated, the rotation of the rotary roll-shaped table is stopped, and the short portion of the pile to be formed by the predetermined uneven portions is appropriately used. It is possible to obtain a concavo-convex pattern that is elongated.

[0015]

As a result of the above, according to the table structure of the shearing device according to the first to fourth aspects, it is possible to reveal an appropriate pattern which cannot be obtained by using the table normally as in the conventional case. . That is, although it is a single table, a wide variety of uneven patterns can be obtained by displacing the table and the uneven portions as if using a large number of tables.

Moreover, the drive control means for displacing the table and the uneven portion can be simply constructed, and, for example, it is not necessary to form the table in a particularly complicated shape, and the manufacturing cost can be kept low.

Further, since the appearance of the uneven pattern is caused not only by the uneven portion of the table but also by the displacement of the table and the uneven portion, various uneven patterns can be obtained depending on the device. That is, it is also possible to obtain a concavo-convex pattern that can be obtained only with a table having a shape that is difficult to manufacture, with a table having a shape that is easy to manufacture, depending on the method of controlling the displacement of the table or the concavo-convex portion.

According to the table structure of the shearing device of the second aspect, in addition to the above-mentioned effects, the entire table is reciprocated, so that the reciprocating means can be simply constructed, and
It is easy to reveal beautiful parallel uneven patterns.

According to the table structure of the shearing device of claim 3, in addition to the remarkable effect achieved by claim 1, since each finger member can be moved separately, the shape of the upper end portion of the finger member can be moved. Depending on the number of lines, the number of movements, and the like, it is possible to reveal even a complicated uneven pattern in which unevenness contacts.

According to the table structure of the shearing device of the fourth aspect, in addition to the effect achieved by the first aspect, since the structure for appropriately blocking the rotation of the rotating table is employed, the existing device can be simply modified. With the structure, it is possible to inexpensively obtain an uneven pattern that could not be easily revealed in the past.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. (First Embodiment) FIG. 1 is an explanatory view showing the structure of a shearing device. As shown in FIG. 1, the shearing device is a table at a predetermined position below a shearing means 3 composed of a spiral cutter 1 and a lower blade 2. 4, piles of the pile fabric 5 are cut and aligned while the pile fabric 5 is conveyed on the table 4 in a mountain shape with the table 4 as an apex.

In this shearing device, there is provided a reciprocating means 6 which reciprocates the table 4 along the length thereof by an appropriate width.

The above-mentioned table 4 has, for example, as shown in FIG. 2, a ring-shaped convex portion 4b on the outer peripheral surface of a cylindrical main body 4a.
Are integrally formed and are rotatably supported via bearings (not shown).

The above-mentioned reciprocating means 6 is, for example, as shown in FIG.
It may be configured as shown in. That is, the worm 8 for inputting the rotational force from the forward / reverse rotation motor 7 is meshed with the rack 10 mounted on the lower surface of the U-shaped frame member 9 for supporting the table 4 so that the table 4 can reciprocate. ing. The forward / reverse rotation motor 7 is controlled by a control unit (not shown) so that the forward rotation, the reverse rotation, and the stop may be performed at appropriate times.
It is controlled by. Therefore, various reciprocating motions are possible depending on the setting. Although not shown, a speed change mechanism is interposed and connected to the control unit described above.

As the reciprocating means 6, the forward / reverse rotation motor 7 as described above may be used, or a reciprocating mechanism based on an appropriate crank movement may be used. It is possible to obtain a reciprocating motion having a constant width and a reciprocating motion having a rest point at the end of the stroke without changing the rotation direction of the motor.

Further, the shape of the above-mentioned table 4 is merely an example, and various tables 4 ... As shown as an example in FIGS. 4 to 8 may be used. The table 4 of FIG. 4 is formed by forming a spiral convex portion 4b on the outer peripheral surface of the main body 4a, and the table 4 of FIG. 5 is a ring-shaped convex portion 4b.
b is diagonally arranged in parallel. Further, the table 4 in FIG. 6 is one in which the step-like convex portions 4b are arranged at equal intervals on the outer peripheral surface of the main body 4a, and the table 4 in FIG. 7 is the one in which similar convex portions 4b are connected in a spiral shape. is there. In the table 4 of FIG. 8, the main body 4a is formed in a long prism shape, and a substantially hemispherical convex portion 4b is formed on the upper end edge. Since the convex portion 4b is formed in a substantially hemispherical shape, the displacement of the table 4 under the pile fabric 5 along the length direction can be performed extremely well. The same thing can be said for each of the above-mentioned convex portions 4b, and therefore, the convex portions 4b have tapered surfaces on both side surfaces as shown in the drawing.

The function and effect of the shearing device thus configured will be described below. First, appropriate conditions are set in the control unit, and the reciprocating means 6 is operated in accordance with the conveyance of the pile fabric 5. Then, the table 4 is set under preset conditions, that is, the rotation speed of the forward / reverse rotation motor 7 based on the setting of the speed change mechanism, the movement width (normal rotation time, reverse rotation time) of the table 4, the stop time at the end of the reciprocating stroke, and the like. Reciprocate based on. According to this reciprocating movement, the convex portion 4b of the table 4 is displaced to a portion which is not normally located while keeping the same interval, and the portion corresponding to the convex portion 4b is shortly formed, and an uneven pattern parallel to the pile fabric 5 is formed. can get.

In addition, in addition, when the rotation speed of the forward / reverse rotation motor 7 is higher than the conveyance speed of the pile fabric 5,
The angle of the uneven pattern becomes steep, and becomes slower at a slower angle. Also, the amplitude of the uneven pattern increases as the movement width of the table 4 increases. Furthermore, if the stop time is long, the same uneven pattern that appears in the normal state can appear for a long time.

Therefore, it is possible to reveal an appropriate pattern which cannot be obtained by using the table 4 as usual, and it is possible to use a large number of tables 4 even though it is one table 4. It is possible to obtain a wide variety of uneven patterns by reciprocating the table 4.

Moreover, the structure of the reciprocating means 6 for displacing the table 4 is simple, and it is not necessary to form the table 4 into a particularly complicated shape, and the manufacturing cost can be kept low.

The appearance of the uneven pattern on the pile fabric 5 depends not only on the uneven portion of the table 4 but also on the displacement (reciprocating motion) of the table 4, so that various uneven patterns can be obtained depending on the device. For example, in the case of the table 4 shown in FIG. 4, in the normal state in which the table 4 is not reciprocated, diagonal parallel unevenness patterns are only formed, but by reciprocating this, the unevenness of the waveform corresponding to the moving width is formed. A pattern is formed. On the other hand, in the table 4 shown in FIG. 5, a wavy concavo-convex pattern having a constant curvature is formed in a state where the table 4 is not reciprocated. In other words, depending on the setting, the configuration shown in FIG.
Even if the table 4 shown in FIG. 5 is used, it is possible to obtain a concavo-convex pattern which is relatively difficult to form and can be obtained only with the table 4 in FIG.

When the reciprocating means 6 is not driven, a predetermined uneven pattern corresponding to the type of the table 4 appears.

(Second Embodiment) In the shearing device shown in FIG. 9, a plurality of projections and depressions formed on the table 11 are provided on the long table base material 12 so as to be movable along the length direction thereof. Of the finger members 13 are provided with a moving means 16 including a cam 14 and a rotating means 15 for appropriately moving the finger members 13.

The table 11 and the moving means 16 described above are
For example, it may be configured as follows. That is, as shown in FIG. 10, the table 11 is provided with an elongated table base material 12 in the horizontal direction, and a plurality of moving holes 17 ... Which penetrate the table base material 12 in the vertical direction and are long in the longitudinal direction. The finger members 13 each having a square columnar shape and upper and lower end portions 13a and 13b formed in a substantially hemispherical shape are held in the moving holes 17 so as to be movable in the longitudinal direction.

The finger member 13 is held by elliptical sliders 13c, 13 formed on both front and rear surfaces of an intermediate portion in the vertical direction.
c is slidably held in slide grooves 18 formed on the front and rear surfaces of the table base 12. The above-mentioned slide groove 18 has a length sufficient for the finger member 13 to move in the moving hole 17.

The table 11 thus constructed
Is held by a U-shaped frame member 21 so as to be located above the cam 14 connected from the motor 19 as shown in FIG. Although not shown, a speed change mechanism is interposed between the motor 19 and the cam 14.

Each of the finger members 13 is attached to the cam 14 described above.
A cam groove 21 for immersing and sliding the lower end portion 13b of
Are forming ... The depth of the cam grooves 21 is preferably long enough to allow the lower end portion 13b of the finger member 13 to be fully recessed in order to ensure the movement of the finger members 13. In addition, at this time, it is preferable to set the cross section to be circular at least in the portion that is recessed in the cam groove 21. This is because, as described above, the lower end portion 13b of the finger member 13 is formed in a hemispherical shape, and sliding in the cam groove 21 can be performed smoothly even in a straight portion or a curved portion.

Since the sliders 13c of the finger members 13 are oval as described above, the finger members 13
When the finger slides in the cam groove 21, the finger member 13
Does not tilt, and the upper end portion 13a also moves in accordance with the movement of the lower end portion 13b. Furthermore, since the upper end portion 13a is also substantially hemispherical, the pile fabric 5 can be moved smoothly.

The above-mentioned cam grooves 21 may all have the same shape, but it is preferable that they are different as shown in the drawing. This is because the feature of this table structure can be utilized by distinguishing it from the configuration of the first embodiment.

If the cam 14 is separated from the motor 19 so that it can be selectively replaced, the same table 11 can be used.
However, the finger members 13 ... Can be displaced differently, and different uneven patterns can be exposed on the pile fabric 5.

Further, in the above description of table 11,
Although it is shown that one finger member 13 is held in one moving hole 17, for example, when it is desired to partially contact the uneven pattern, one moving hole 17 is provided as shown in FIG. 12, for example. It suffices to hold a plurality of finger members 13 and 3 such as two and to form cam grooves 21 and 21 on the cam 14 that are in contact with each other as shown in the drawing. You can obtain more diverse uneven patterns.

Furthermore, when it is not desired to form a concavo-convex pattern that is continuous in the conveying direction of the pile fabric 5, not only the finger member 13 is moved in the left-right direction, but also the concave pattern is formed, for example, as shown in FIG. The finger member 13 may be configured to move downward in a portion where it is not desired to expose. That is, the slide groove 18 is formed to have a width in the vertical direction as well as is formed larger than the slider 13c, and the recess 21a is formed in the cam groove 21 of the cam 14. In addition,
Even if the slide groove 18 has a width in the vertical direction, the actual width of vertical movement is only a few mm, although it is exaggerated in the drawing.
As long as the lower end portion 13b of the finger member 13 is sufficiently recessed in the cam groove 21, the inclination of the finger member 13 does not matter.

In the shearing device thus constructed, when the moving means 16 is actuated, the cam 14 rotates at a speed corresponding to the rotation speed of the motor 19 preset by the speed change mechanism, and the fingers forming the convex portions of the table 11 are rotated. Each of the members 13 ... Is moved laterally. That is, since the respective finger members 13 ... Can be moved separately, even if a complicated uneven pattern such as uneven contact is present depending on the shape and number of the upper end portions 13a of the finger members 13 ... You can get out.

Further, since the uneven portion of the table 11 is formed by using the finger members 13, ... As described above, not only the finger members 13 are moved in the left and right directions, but also the finger members 13 are lowered at a predetermined portion to eliminate the concave pattern. You can also let it. For this reason, it is possible to obtain the above-mentioned pattern within a longer range, which was conventionally obtained only within the range of the length of the outer peripheral surface of the main body in the rotary roll table.

(Third Embodiment) In the shearing device shown in FIG. 14, the table 31 is formed in the shape of a rotating roll that rotates in synchronization with the conveyance of the pile fabric 5, and the rotation that blocks the rotation at an appropriate position. The control means 32 is provided and comprised.

The above-mentioned table 31 may be, for example, one in which the convex portion 4b is formed on the outer peripheral surface of the cylindrical main body 4a as shown in FIGS. 4 to 7 shown in the first embodiment. The table 4 of FIG. 2 of the first embodiment is excluded only because a straight concave pattern appears because the convex portions 4b of the table 4 are ring-shaped and parallel to each other. Therefore, even if the rotation of the table 4 is stopped, no significant difference is seen in the uneven pattern.

The rotation control means 32 may be constructed as follows, for example. That is, as shown in FIG. 15, an electromagnetic brake 33 is attached to the rotary shaft 31b of the main body 31a of the table 31 described above, and the electromagnetic brake 33 is attached to the sensor 34 for detecting the position of the outer peripheral surface of the main body 31a of the table 31.
It is configured to operate based on the detection of. 3 in the figure
5 is a bearing.

The position of the outer peripheral surface of the main body 31a of the table 31 is, for example, in the case of the table 31 having the convex portion 31c having the shape shown in the developed view of FIG. The table 31 is an appropriate portion that can reveal an uneven pattern that cannot be obtained when the table 31 rotates normally. The table 4 shown in FIGS. 4 to 7 in the first embodiment also corresponds to, for example, an inclined portion or a linear portion in the length direction.

Further, convex portions 36 ... Are formed on the outer peripheral surface of the table 31 corresponding to them. As shown in FIG. 15, the convex portions 36 ...
That is, when it is located at a position that acts as the table 31, the above-mentioned sensor 34 constituted by a proximity switch is used.
Detected by.

The above-mentioned components are connected as shown in the block diagram of FIG. That is, the signal detected by the sensor 34 is sent to the control unit 37 including a CPU or a sequence circuit, and whether or not the electromagnetic brake 33 is activated via the relay switch 38 based on a preset condition. It is determined. When the electromagnetic brake 33 is activated, the timer 39 measures the time,
After measuring the set conditions, the electromagnetic brake 33 is released.

In the shearing device having the above-described structure, for example, the sensor 34 outputs 1 each time the convex portion 36 is detected twice.
An appropriate condition is set in the control unit 37 in advance, such as “turn”. Then, by the operation of the rotation control means 32, the table 31 rotating in synchronization with the pile fabric 5 is stopped by the electromagnetic brake 33 according to the above-mentioned predetermined condition. This stop time is measured by the timer 39,
When the time measurement is completed, the electromagnetic brake 33 is released, and the pile fabric 5 is rotated again in synchronization. Since such an operation is performed, a concavo-convex pattern is obtained in which the short portion of the pile to be formed by the convex portion 31c is extended at predetermined positions according to predetermined conditions.

Therefore, since the rotation of the rotating table 31 is properly prevented, the existing device has a simple structure in which a slight modification is required, and an uneven pattern which cannot be easily revealed in the past is inexpensive. Obtainable.

Although one embodiment of the present invention has been described above with reference to three embodiments, it is also possible to appropriately combine the configurations of these embodiments.
