Description

[Detailed explanation of the invention] (Industrial application field) This invention is applicable to running fabrics such as woven fabrics, knitted fabrics,
While running a long fabric such as film or paper,
In the processing technology that performs dyeing and other treatments, it relates to a meandering correction machine for running fabric that is used to correct the running fabric to a proper running position when it meanders in the left and right directions. The invention relates to an improvement of a mounting device for a sliding bar for correcting the meandering of running material, which is provided in the correcting machine, and is used in the field of manufacturing technology for this type of equipment.

(Prior Art) Many types of meandering correction machines for running fabric have been proposed in the past, but the inventor of the present invention previously proposed this type of meandering correction machine for the purpose of compacting the overall shape. (Special application 1986-
No. 27298). As shown in Fig. 4, the configuration of this meandering correction machine is as shown in Fig. 4.
At the same time, bearings C and C are fixed to the shaft A.
A cylindrical body D is rotatably fitted through the cylindrical body D, and a guide ring F having guides _F1 for the sliding bar E disposed in radial lines is fitted at multiple locations on the outer peripheral surface of the cylindrical body D. In addition, each guide F ₁ is connected to the cylindrical body D
The rings F and the cylindrical body D are fixed to each other by bolts G, as shown in FIG. 5, while being linearly arranged in the axial direction. In addition, each sliding bar E
is fitted in a dovetail groove to each of the guides _F1 arranged in the axial direction so as to be slidable in the axial direction, and at one end of each of the sliding bars E, there is a bar with a virtual center point H as the center. A tilting ring-shaped guide frame I is freely connected. Furthermore, the guide frame I is
Two screw shafts with different pitches J ₁ and J ₂
and non-rotating nut members K ₁ , K ₂ screwed thereon, and a drive mechanism L consisting of a motor, pulley, transmission belt, etc., which rotates both the screw shafts J ₁ , J ₂ at fixed positions, the center point is It is provided so as to tilt in the axial direction about H. This tilting operation is performed by sliding each sliding bar E in the left-right axis direction separately and corresponding to the inclination angle of the guide frame I, based on the detection signal from the edge edge detector N of the running material M. In order to move the fabric M, the fabric M is rotated and run while contacting each sliding bar E, and the fabric M is transferred in the sliding direction of each sliding bar E, and the required deviation correction is performed. .

By the way, since the sliding bars E...E provided in the above-mentioned meandering correction machine are fitted into each guide ring F...F and are constantly slid in the axial direction, both E and F are on the contact surface. Although it is necessary to replace it after the required time has elapsed due to wear, when removing the guide rings F...F from the cylindrical body D and replacing them with new ones, replace the left and right brackets B, B or the screw shaft. Brackets B' and the like for J ₁ and J ₂ were an obstacle, making it extremely difficult to replace them.

In addition, both the guide ring F and the cylindrical body D are fixed with bolts G, but when the guide ring F is fixed to the outer peripheral surface of the cylindrical body D, it is fitted into each guide _F1. It is necessary to dispose the sliding bar E so that it can slide smoothly in the axial direction. Therefore, each guide F ₁ that protrudes radially in the circumferential direction of the guide ring F is aligned with the axial center line of the cylindrical body D. In order to accurately align the two on straight lines parallel to each other, a great deal of time and careful attention was required for positioning.

Furthermore, since the cylindrical body D is made of a steel pipe, it has the disadvantage that the overall weight is heavy, and the guide rings F are manufactured by separate machining processes, which makes manufacturing them cumbersome. In addition, in order to fit the cylindrical body D and the left and right bearings C, C, it is necessary to cut the fitting inner peripheral surfaces on both sides of the cylindrical body D into the required shape. etc., the actual assembly and disassembly work required a great deal of effort and was considered to be a cause of increased product costs.

(Problems to be Solved by the Invention) The present invention is to install sliding bars that can efficiently and reliably maintain the sliding movement in the axial direction of each sliding bar provided on the outer peripheral surface of the cylindrical body. By providing a device and configuring the fitting support guide of each sliding bar so that it can be easily and reliably assembled, removed and disassembled from the cylindrical body,
By simplifying the overall assembly and disassembly work of the product, making it easier to handle the product, and reducing costs, we hope to reliably solve the problems in actual use as described above. This is the purpose.

(Means for Solving the Problems) As a means to solve the above problems and achieve the purpose, the present invention provides a cylindrical body of a required length and a removably fixed body to the outer peripheral surface of the cylindrical body. It consists of a guide for fitting the sliding bar and a removable member for both the cylindrical body and the guide, and the removable member has an axial direction formed at a required interval in the circumferential direction on the outer peripheral surface of the cylindrical body. a plurality of engagement grooves formed on the guide, a forked engagement protrusion that engages with the engagement groove formed on the guide, and the engagement protrusion of the guide that is attached to and detached from the engagement groove of the cylindrical body. The crimping fixture is composed of a crimping fixture that can be freely crimped and fixed, and the engaging groove is provided with engaging recesses facing each other on both sides, and the crimping fixture is configured to fit into the forked engagement protrusion of the guide. A wedge for expanding the forked engagement protrusion is fitted in between, and the forked engagement protrusion is pulled upward by threading the wedge to expand the forked engagement protrusion. We have developed a mounting device for a sliding bar in a meandering correction machine for running fabric, characterized in that it is comprised of wedge bolts that are crimped into both engagement recesses, respectively.
Adopted.

(Function) According to the configuration of the present invention, the guide for fitting the sliding bar is detachably fitted into the engagement groove of the cylindrical body via the detachable member, so that the work of attaching and detaching the guide to the cylindrical body is easy. will be simplified.

Further, by providing engaging recesses on both circumferential sides of the engaging groove of the cylindrical body and removably press-fitting the bifurcated engaging protrusions of the guide to both recesses, the guide can be installed in a well-balanced manner on the left and right sides of the cylindrical groove.
Even if the rotational direction of the cylindrical body is changed depending on the mode of use, the sliding action of each sliding bar is not hindered, and therefore, the meandering correction function of each sliding bar can be quickly adapted to such changes. You can definitely get it.

(Embodiment) Next, an embodiment of the present invention shown in FIGS. 1 to 3 will be described.

FIG. 1 shows the main parts of a machine for correcting the meandering of running fabric 1, which includes a rotatably installed roll 2 for correcting meandering (deviation) of running fabric 1, and
and a drive mechanism 3 that causes the meandering correction roll 2 to perform a required correction action based on a detection signal from an edge detector (not shown) which detects meandering.

The roll 2 is rotatably fitted to a center shaft 5 which is fixed in a non-rotating state between left and right brackets 4 (not shown on the right side) via left and right bearings 6 (not shown on the right side). As shown in FIG. 2, it is provided so as to be rotated in the same direction as the running material 1 is transported.
The left and right bearings 6 are made of light alloys.
For example, a cylindrical body 7 of a required length formed by a precision drawing process is fixed, and the cylindrical body 7 is rotatable about the axis of the shaft 5. In addition, each of the required interval positions in the circumferential direction on the outer circumferential surface of the cylindrical body 7 (in the illustrated example,
Engagement grooves 8...8 in the axial direction are formed at six locations at circumferential intervals of 60 degrees.
Engagement recesses 8 ₁ and 8 ₂ of a required depth are provided facing each other on both sides in the circumferential direction. By forming the cylindrical body 7 by precision drawing, the grooves 8 can be arranged accurately in the axial direction, and the inner diameter can also be formed accurately. It is possible to omit the process of machining the inner circumferential surface that is necessary when fitting it to the outer circumference of the groove 6, and in order to maintain the durability of the groove 8, it is necessary to adjust the thickness and shape of the groove 8. This can be dealt with by configuring the system appropriately.

In addition, guides 9 (right side not shown) made of hard synthetic resin are removably pressed into at least two positions on the left and right sides of each of the grooves 8 . . . 8 . This guide 9 has both recesses 8 ₁ and 8 ₂ in the groove.
Forked engagement protrusions 9 that are engaged with each other
₁ , 9 ₂ and horizontal sliding bar fitting portions 9 ₃ formed integrally with the protrusions, and
The guide 9 is formed relatively short, as shown in FIG. Therefore, the guide 9 can be easily fitted into the groove 8 via both projections 9 ₁ and 9 ₂ , and can also be easily removed from each groove 8. Furthermore, the guide 9 is crimped and fixed to the groove 8 by a crimping fixture 12 consisting of a wedge 10 and a wedge bolt 11. That is, with both the protrusions 9 ₁ and 9 ₂ of the guide engaged in both the recesses 8 ₁ and 8 ₂ in the groove, the wedge 10 is fitted onto the opposing surfaces of the protrusions 9 ₁ and 9 ₂ , Next, the wedge 11 is inserted through the bolt hole 13 formed in the horizontal fitting part ₉₃ of the guide (it is preferable that the bolt 11 is rotatably mounted in the bolt hole 13). A screw hole 10 ₁ is formed in the wedge 10 with a threaded portion 11 ₁ .
and then screw the wedge 10 with the bolt 11.
By moving in a required direction, the forked protrusions 9 ₁ , 9 ₂ are expanded to form both recesses 8 ₁ , 8 ₂ of the grooves.
They can be press-fitted and crimped into each other.
Note that the tapered surfaces 14 and 15 formed on both the projections 9 ₁ and 9 ₂ and the wedge 10 are such that, in the illustrated example, the wedge 10 is moved toward the horizontal fitting portion 9 ₃ of the guide. Although the case is shown in which both protrusions 9 ₁ and 9 ₂ can be expanded by
For example, the tapered surfaces of both the protrusions 9 ₁ , 9 ₂ and the wedge 10 are formed in opposite directions, and the wedge bolt 11 is rotatably mounted on the horizontal fitting portion 9 ₃ side of the guide. In addition, a configuration (not shown) may be adopted in which the threaded portion of the bolt is always screwed into the threaded hole of the wedge. In this case, by moving the wedge 10 toward the groove 8 side, both protrusions 9 ₁ and 9 ₂ can be expanded, so that almost the same crimping fixing effect as in the example shown can be obtained, and the wedge Since the bolt 11 is rotatably mounted on the guide 9 side, the wedge 10 and the guide 9 can be always combined via the wedge bolt 11, which is advantageous in that parts management can be ensured. When the guide 9 is released from the crimped and fixed state, the wedge 10 can be reliably moved in the direction in which the spreading force of both the protrusions 9 ₁ and 9 ₂ is removed. This is advantageous in that the wedge effect on 9 ₁ and 9 ₂ can be easily and reliably released.

In addition, sliding bars 16 are attached to at least two left and right guides 9 that are crimped and fixed to each of the grooves 8...8.
...16 is fitted so as to be slidable in the axial direction. This sliding bar 16 is connected to the horizontal fitting part 9 of the guide.
a fitting sliding portion 16 ₁ that is dovetail-fitted to ₃ ;
Running fabric 1 integrally fitted into the fitting sliding portion 16 ₁
The sliding portion 16 ₁ is made of a light alloy, and the contact portion _{16 2 is} made of an elastic material such as rubber. Therefore, each of the guides 9 is fixed to the groove 8 of the cylindrical body 7 disposed in the axial direction, and each of the sliding bars 16 is fixed to each horizontal groove of the guide arranged in a straight line in the axial direction. Shape fitting part 9 ₃
As a result, each sliding bar 16 is fitted so as to be slidable in the axial direction of the cylindrical body 7.

The drive mechanism 3 described above includes a servo motor 17 provided to operate based on a detection signal from an edge detector that detects meandering of the running material 1.
The rotational force of the motor is transmitted to the timing pulley 18,
19, 20 and the timing belt 21,
A transmission member 24 transmitting power to the two screw shafts 22 and 23 which are supported in parallel with the axial direction of the shaft 5, and
Nut members 25 and 26 screwed onto the shafts 5 and screw shafts 22 and 23, respectively, and a guide frame 27 for the sliding bars 16 and 16, which are comprised of two left and right ring plates fitted around the outer circumference of the shaft 5 and each screw shaft 22 and 23. The pitches of the two screw shafts 22, 23 are different in size, and the diameters of the timing pulleys 19, 20 fixed to each of the shafts 22, 23 are the same. , the guide frame 27 is pivotally attached to each of the nut members 25, 26 via pivot pins 28, 28, respectively.
6 and the guide frame 27 are provided so as not to rotate in the circumferential direction. Further, between the left and right ring plates of the guide frame 27, there are sliding bars 16, 1.
Rotating rollers 30, . . . , 30 are rotatably fitted and supported on the left end portions of the rollers 6 via roller brackets 29, respectively.

Therefore, the above two screw shafts 2
2 and 23 are equally rotated in the same direction by the rotational force of the motor 17, but each nut member 25 and 26 screwed thereon is moved in either the left or right direction corresponding to the respective pitch. At this time, since the moving distances of the respective nut members 25 and 26 are different, the guide frame 27 is tilted in either the left or right direction using the virtual center point 31 as a fulcrum. That is, by rotating the motor 17 forward and backward, the guide frame 27 can be tilted to the left or right, using the virtual center point 31 as a fulcrum. 2
It is slid in the left or right axial direction, respectively, corresponding to the tilt angle of 7. Further, each bar 16 is rotated in the direction of transport as the running fabric 1 is transported, and the rotating rollers 30 on each bar 16 side
are fitted and supported between the left and right ring plates of the guide frame 27, so each bar 16...16 can rotate freely in the circumferential direction. For this reason,
The fabric 1 that is transferred while contacting each of the bars 16...16 is subjected to a meandering correction action in the left-right direction due to the sliding of each bar 16 in the left-right axis direction.

In the embodiment described above, when the guide 9 is attached to the cylindrical body 7, both the protrusions 9 ₁ and 9 ₂
are engaged in both recesses 8 ₁ and 8 ₂ in the grooves of the cylindrical body, respectively, and the wedge 10 fitted between the projections 9 ₁ and 9 ₂ is moved in the required direction by the bolt 11. The projections 9 ₁ and 9 ₂ may be press-fitted into the recesses 8 ₁ and 8 ₂ , respectively, and the guide 9
When removing the cylindrical body 7 from the cylindrical body 7, it is sufficient to perform the procedure in reverse to the above-described procedure.

Therefore, since the guide 9 can be attached to and detached from the cylindrical body 7 through the simple procedure described above, it is possible to simplify the disassembly work when assembling and maintaining the meandering correction roll 2. There is an effect that can be done. In particular, the guide 9 is attached to at least two left and right places of the groove 8 on the cylindrical body, but since the groove 8 is formed directly in the axial direction of the cylindrical body 7, the guide 9 is attached to the groove 8 in the cylindrical body. They can be arranged in a straight line in the axial direction along the groove 8, which has the effect of omitting delicate adjustment work such as positioning the horizontal fitting portion ₉₃ of the guide.

In addition, in practice, it is possible to restore the good sliding function of the sliding bar 16 by simply replacing the guide 9, which is economical, and the cylindrical body 7 and the sliding portion 16 of the sliding bar ₁ etc. can be made of light alloys, which reduces the overall weight of the device and makes it easier to handle.Furthermore, the device can be manufactured easily and costs can be reduced. Also,
Both protrusions 9 ₁ and 9 ₂ of the guide 9 are formed in a bifurcated shape with left and right symmetry, and are attached to the grooves 8 of the cylindrical body with good left and right balance.
Even if the rotational direction of the cylindrical body 7 based on the transfer direction of the sliding bar 1 is changed depending on its usage, the sliding bar 1
Since the sliding action of the sliding bars 6 is not obstructed, it is possible to obtain a meandering correction action of each sliding bar that can immediately respond to such changes.

(Effects of the invention) According to the configuration of the invention, the fitting support guide of each sliding bar can be easily and reliably attached to and removed from the cylindrical body, so the overall product assembly and
This has an excellent practical effect of simplifying the disassembly work, and thereby making it easier to handle the product and reducing costs.

In particular, since each bar is attached to an axial groove formed on the outer periphery of the cylindrical body, the horizontal fitting parts of each guide installed in the same groove are arranged in a straight line in the axial direction. Therefore,
Unlike conventional guide rings, it is possible to omit the delicate adjustment work such as positioning between the fitting parts where the sliding bar is fitted, and the guide in this invention can be easily attached and detached from the groove of the cylindrical body. Because it can be used as a guide ring, it is possible to save labor in disassembling and reassembling the guide ring compared to conventional guide rings.
Since the guide in the present invention is installed in a well-balanced manner in the grooves of the cylindrical body, the sliding bar fitted to the guide can be rotated in any direction.
This provides the advantage of always being able to slide smoothly.
