Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for removing a wire that protrudes from a cross section of a transmission belt sleeve using a metal wire in a core wire spirally embedded in the circumferential direction of the belt sleeve.
[0002]
[Prior art]
Conventionally, in a circular cut of a transmission belt sleeve using a metal wire composed of a stranded wire made of a thin metal wire as a core wire, a carbide cutter blade while rotating the cylindrical sleeve on the rotating shaft while preventing meandering Was pressed and gradually cut in thickness, and was cut with a normal cutting device.
[0003]
However, in this incision, the metal wire that is embedded by spirally winding in the cylindrical sleeve passes through the cut cross section slowly and obliquely, so the metal wire is cut obliquely in this cut cross section. The core wire embedded therein could not be cut due to movement, and the core wire was cut in a connected state only by cutting the belt elastic material that wrapped the core wire.
[0004]
Also, even if it can be cut diagonally along the cut section, it is not possible to hold this diagonal end so that it does not peel from the side of the running belt, and efficient cutting of the core wire is desirable to cut at right angles. The core wire that crosses the belt cut section is cut at a substantially right angle, and the core wire is removed by pulling in advance to a position where the end portion of the core wire after cutting does not protrude from the side surface of the belt.
[0005]
In this removal, there are many belt size types, and the belt itself is an indeterminate shape having elasticity, and since it has a high investment risk to handle it mechanically, it has been handled manually. This core wire removal work is done by cutting the core wire between the belts that have been cut after the width cut, and cutting the core wires one by one by hand. Nippers in a state where a belt is hung on a table, and the core wire that passes diagonally through both sides of the belt is pulled out and pulled around its circumference with a hand that grips the end of the core wire exposed on both sides of the belt with pliers. The core wire intervening on the side surface of the belt was cut off and removed in advance.
[0006]
However, it is a work that is manually pulled out, which places a burden on the wrist, necessitates work replacement, and is forced to deal with a lot of loss in terms of personnel placement. Improvements were desired because of variations.
[0007]
[Problems to be solved by the invention]
It is an object of the present invention to provide a technique for removing a core wire from a side surface of a belt based on a simple machine response that can be performed by light work without force work.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, that is, in the method of claim 1, the core wire which pulls out the core wire exposed on each cut side surface of the cut sleeve body in a state where the core wire is still connected to the belt width. In the wire removal method,
A cut sleeve body is hung between two cantilever shafts, and one belt at the front end of the cantilever shaft is placed between the other two cantilever shafts facing the two shaft ends. Separate and move, pull the core wire between the separation surfaces of the belt which is separated and hung between the left and right axes and lead it to the uppermost or lowermost position between the two axes, the core wire is horizontal Align the core wire that is stretched and exposed between the sides of the belt, align the core wire, position the core wire, and insert the winding shaft into the center of the core wire where the exposed position is fixed and the exposed state is aligned. Catch the wire, wind the core wire around the take-up shaft, pull out the core wire that passes diagonally through the belt cut section, and place and hold the core wire that is held and stretched in the finished winding state. Both two spaced apart axes And core wire wire cut simultaneously at the base which is exposed on the surface, the facing 2 on one of the two axes of cut pulling the cord wires can be performed by removing the single belt suspended.
[0009]
According to this, the wire core wire is connected to the cut cross section, it is possible to hold the cut sleeve body that is easy to collapse and difficult to grasp, and can be opened by rolling the cut cross section for each cut belt, and the wire straddling this open space The position and orientation of the core wire can be determined to be almost the same regardless of the belt type, the core wire pull-out position is fixed, and the pull-out amount can be controlled by the rotation amount of the winding shaft, and the core wire is at the fixed pull-out position Can be cut, one belt that has been cut after the core wire is cut can be ejected, and an automatic mechanism that can move to the next cut can be created.
[0010]
In the method of claim 2, the separation movement in which the cut sleeve body is hung between one cantilevered two shafts and the other cantilevered two shafts is hung on the cut sleeve body. The other cantilevered two shafts in the opposite state where the shaft center ends of the two cantilevered shafts are aligned and the front end portions of the cantilevered shafts are butted against each other. A sleeve that has been cut by pushing the belt width in the axial direction from the rear end of the cut sleeve body that is hung on one cantilevered two shafts while preventing the sleeve from lifting up with a pressing roll adjacent to the upper shaft from the side. Move the body to the other two cantilever shafts, position the cut surface part on the end of the butt shaft, divide the partition wall built in the shaft end surface into the cut boundary surface, and separate the two butt shafts. To separate It can be.
[0011]
According to this, it is possible to prevent the separation from the end of the cantilever shaft due to the pulling of the core wire at the time of separating and separating one by one from the cut sleeve body to which the core wire is connected in the cut cross section. In addition, it is possible to reliably prevent protrusion at the shaft end.
[0012]
In the method of claim 3, the straddle posture of the core wire exposed between the belt side surfaces is extended by extending the abutting interval between each cantilevered two shafts in the opposed state in claim 1 and extending the core wire horizontally. The core wire on the belt end face is positioned by aligning the core wire extending over the belt cut surface separated by separating the two butt axes and pulling the guide bar up and down in this separation space in either direction. The wire exposure position can be rotated to the uppermost part or the lowermost part, and can be centered by the V-shaped guide groove provided in the partitioning rod part.
[0013]
According to this, the core wire that remains connected to the cut cross-section straddles the space where the cut cross-section is separated and opened in an indefinite state, and the contact mechanism to the core wire can be performed with a simple touch that moves the horizontal bar up and down. When moving the horizontal bar up or down, the core wire is lifted or hung and lifted to lift the core wire exposure start position on the side of the belt, thereby exposing it to the uppermost part while rotating between two axes. Move the start position. It can be positioned in the center position just by sliding into the V-groove of the ridge in the vicinity.
[0014]
In the method of claim 4, the winding wire is inserted into the central portion of the core wire in which the exposure position is fixed and the exposed state is aligned in claim 1, the core wire is caught and the core wire is wound up. The drawing of the core wire that is wound around the shaft and obliquely passes through the belt-cut section can be caught by providing a split groove at the front end of the winding shaft, and the length of the core wire can be determined by the amount of rotation.
[0015]
According to this, the core wire can be surely caught by the split groove extending to the tip, and the core wire can hardly be slipped at the time of winding, and the amount of the core wire can be adjusted by the amount of rotation of the winding shaft.
[0016]
According to a fifth aspect of the present invention, there is provided a core wire which is exposed from the side surface of the belt at both end surfaces between the two axes where the core wires held and stretched in the winding end state in the first embodiment are opposed to each other and the butting interval is opened. The core wire cut that cuts the base of the wire at the same time releases the front end face partition between the two butted shafts and presses the belt side against the guide groove with the V groove along the cutting blade surface. I can cut it.
[0017]
According to this, a thin partition rod attached to the shaft end face has a part of its outer diameter that is the same as the shaft diameter, and a part of which is larger than the shaft diameter by approximately the belt thickness. When cutting the core wire, insert a guide claw with a V-groove provided along the blade surface, reverse the thin partition rod mentioned above, change the position of the large collar and release the belt end that was partitioned Therefore, the cutter blade can be applied to the root of the core wire exposed on the side of the belt.
[0018]
In the structure of Claim 6, the core wire exposed to the cut section of the cut sleeve body in which the core wire is still connected after the belt width cut in Claim 1 is drawn out and removed for each belt. When removing the core wire to be finished, the cut sleeve body is hung between two cantilevered shafts, and one belt at the open end of the cantilevered shaft is placed opposite to the other two shaft ends. Pulling the cord wire straddling between the belt end surface that is separated and moved between the two shafts and the belt end surface that is separated between the two left and right shafts in the vertical direction, the exposed position of the core wire on the belt end surface is 2 A core wire positioning means for expanding the core wire to align the posture of the exposed core wire by further expanding the abutting opposed arrangement interval in accordance with either the uppermost position or the lowermost position between the axes; A core wire pulling means for inserting the winding shaft into the central portion of the core wire that is fixed in the exposed position and aligned in the exposed state, and rotating the core wire around the core to wind the core wire around the winding shaft; A core wire that cuts and extends the core wire that has been stretched and held at the end of winding, and simultaneously cuts at the root exposed at both end surfaces between the two axes, and the core wire on one of the two opposite axes And a belt take-out means for discharging the suspended belt after the drawing cut.
[0019]
According to this, if the cut sleeve body is set to the machine all at once, the belt after the removal of the core wire is discharged, and the cut and removal of the core wire across the cut section can be handled with a simple mechanism.
[0020]

First, the cut sleeve CS is a transmission belt using a metal wire as a core wire. For example, a metal wire is spiraled as a core wire on the outer periphery of an inner die provided with a tooth shape on the outer periphery of a cylindrical shape. Obtained by pouring resin into a cylindrical cavity formed from an outer mold and an inner mold that are concentrically assembled to a cylindrical outer mold with a bottom and cured. In addition, it can be used in the same way for a round cut process of a cylindrical sleeve in which a metal wire is wound around a belt core wire in a spiral shape and embedded.
[0021]
Next, the method for removing the core wire from the side surface of the belt according to the present invention will be described. FIG. 1 and FIG. 2 show a removal process flow and an outline of the process, which are performed in the following five main steps 1) to 5). Hereinafter, the core wire is simply referred to as a wire.
[0022]
First, the cut sleeve CS is hung between the cantilevered two shafts 15a and 15b to separate and open the cut surface. 1) Separation and movement process, unifying the wire W exposed and straddled in the spaced space with its posture and position aligned 2) Wire alignment step, then catch the exposed wire with the take-up shaft 25 and take up the exposed wire as a shaft, and draw out the wire W interposed in the belt cut section 3) Wire drawing step, then wire at the draw end Cut the W 4) Wire cutting process, remove the single belt from which the wire straddling the belt cut cross section is removed 5) Remove the belt, and repeat this process to repeat the belt side of the cut sleeve Remove the wires.
[0023]
The details will be described below. First, as shown in FIG. 1, the separation and movement process is performed by (a) hanging and (b) opening the cut section, and cutting and expanding the cut section of the cut sleeve CS connected to the wire W by cutting the wire. Space for removal processing is secured. In the first (a) hanging, the set of cut sleeves CS with the wires connected are inserted from the open end of the cantilevered two shafts 15 and hung between the two shafts 15 to be stretched.
[0024]
Next, (b) when the cut section is opened, the belt at the end of the open shaft is moved to the other cantilevered two-shaft 16 side that faces and separates to secure a space for separating the cut section and extracting the wire. To do. This separation procedure is shown in FIG. 3. First, as shown in FIG. 3 (a), the other cantilevered two shafts 16a and 16b facing the open end of the above-mentioned suspended cantilevered two shafts 15a and 16a are opened. Cantilever with two ends 15 and 16 abutted against each other, sandwiched by presser rolls 17a and 17b so as not to float, and pushed by the width of one belt from the rear end of the suspended cut sleeve CS. Move to the biaxial 16 side.
[0025]
Next, as shown in (b), the partition rods 20a and 20b having a diameter larger than the shaft diameter are inserted into the belt cut boundary surface to divide the cut cross section, and at the same time, the belt side slip stopper is used to separate the two shafts 15 and 16 from each other. Isolate. For setting and releasing the partition rods 20a and 20b, as shown in FIG. 4, a flange 20 having a part of the outer periphery larger than the rotation shaft diameter is provided on the end surface of the central shaft 49 of the outer cylinder 48 that rotates. Swing from the outside to swing the peak y.
[0026]
Here, as shown in (c), in the stage before reaching the state where the butt end is separated and moved, the partition bar 20 is swung and set, the cut cross section is separated, and a stopper is provided, and the wire straddling between them at the time of separation movement The belt can be prevented from coming off against pulling.
[0027]
Next, 2) the alignment process of the exposed wires is performed by (c) wire exposure position movement and (d) wire exposure positioning as shown in FIG. To simplify the wire catch in the next process. The straddling posture here is a substantially horizontal straight state between the opposed two shafts 15 and 16, and the straddling position is selected from the topmost position or the bottommost position of the suspension two shafts 15 and 16 that can be moved simply by pulling in the subsequent process. However, another position can be selected by adding a positioning member or the like to the belt peripheral surface portion.
[0028]
First, (c) wire exposure position movement is performed by hooking the wire exposed to the separation space by the pulling member 24 as shown in FIG. 3C to set the uppermost position or the lowermost position of the upper shafts 15a, 16a and the lower shafts 15b, 16b. By further pulling the belt, the belts CS and B pulled upward as shown in FIG. 5 move the wire exposed position on the side surface of the belt to the topmost position while being drawn between the two shafts 15 and 16. During this time, as described above, the partition rods 20a and 20b at the ends of the shafts 15 and 16 are set to the rod set side to prevent the belt from falling off.
[0029]
Subsequently, (d) wire exposure positioning is performed by moving the wire exposure position as described above (c) as shown in FIG. The wire exposure start portion guided in the vicinity of the notched groove g is further centered and positioned and aligned in a horizontal straight line. That is, the pulling member 24 in the previous process is accommodated, and the wire W that is loose between the belt side surfaces is stretched (S2) and converged to the bottom of the V-shaped groove g of the heel y to form a horizontal linear V-shaped groove. The exposed wire is aligned with the bottommost top position or bottommost position.
[0030]
Next, as shown in FIG. 2, 3) the wire drawing process is (e) catching the center of the wire, (f) inserting the guide claw and winding the wire. W is peeled off to the side of the belt and pulled out. The pulling amount varies depending on the belt circumference, the core wire winding pitch, and the core wire diameter, but can be controlled by the winding rotation amount.
[0031]
First, (e) the catch at the center of the wire is as shown in (e) while lowering the exposed wire aligned in the horizontal straight line at the highest position in the separation space in the previous step (d) as shown in FIG. The wire W is surely caught by being caught in the split groove portion opened in a trumpet shape at the front end portion.
[0032]
Next, (f) the guide claw 29 is inserted and the wire winding is stretched (S3) so that the wire cutting means 8 capable of simultaneously cutting both ends of the butt shaft interval can be inserted, and the guide claw 29 provided in the wire cutting means 8 will be described later. The wire exposed portion is securely supported as shown above, and the amount of rotation of the take-up shaft 25 is controlled by inserting the wire W into the trumpet-shaped split groove at the front end of the take-up shaft 25, so that the belt type Wind up with the set amount obtained every time. During this time, the belt shafts 15 and 16 have the shaft ends of the upper shafts 15a and 16a at the ends of the guide claws 29 and the ends of the lower shafts 15b and 16b by the partition rods 20a and 20b so that the belts CS and B do not come off the shaft ends. Is supported.
[0033]
In order to securely support the wire exposed portion with the guide claw 29, for example, as shown in FIG. 6, the two ends 15 and 16 are stretched (S 3) at intervals where the wire cutting means 8 can be inserted, and the shaft end face is partitioned. The hook 20 is made to act on the set side, and the wire cutting means 8 is surely inserted, and the guide claw 20 reliably supports the wire, and the state shown in FIG.
[0034]
Subsequently, when the partition rod 20 on the end faces of the butted two shafts 15 and 16 is swung to the release side, the peak portion y of the collar that has stopped the lateral movement of the belt until now is removed, and the state shown in FIG. The belt side surface can be directly supported by the outer surfaces of the guide rods 29a and 29b, and the belt side surface can be received by the blade surface of the nipper along the belt.
[0035]
4) In the wire cutting step, as shown in FIG. 2 (g), the wire W removed in the previous step (f) is wound up, and the removal position of the wire is drawn out to the side surface of the belt to form a V-shaped guide groove. It is positioned at the contact point with the guide claw 29 having m, and this is similarly positioned on both side surfaces of the separated belt. As shown in FIG. 6 (b), the wire W to be cut is positioned on the side surface of the belt, and can be cut from the roots by the nippers 28a and 28b having a pinch shape. While the cut-out wire W is wound around the take-up shaft, an extruding collar (not shown) inserted into the take-up shaft is pushed out to the tip of the take-up shaft along with the retreat operation of the take-up shaft 25 upward. Can be discharged.
[0036]
Subsequently, as shown in FIG. 2 (h), the belt removing step 5), as shown in FIG. 2 (h), the wire W is removed and one belt B suspended between the cantilevered two shafts 16 is moved to the open end side. The pushing member 31 is pushed out from the rear side to be removed, and is hooked on the turning arm 32 and carried out to the next process.
[0037]
Next, an embodiment of the core wire removing device embodied by using the above-described method of removing the core wire on the side surface of the belt will be described with reference to FIGS. First, the main parts of the core wire removal device 1 are the hanging means 3 (spreading the cut surface of the cut sleeve), the wire aligning means 5 (aligning the posture and position of the exposed wire across the cut surface), and the wire pulling means 6 (Drawing out the protruding wire obliquely crossing the cut section), wire cutting means 8 (extracting the drawn wire at the root), and belt taking out means 9 (discharges the belt-removed belts on both sides). Each will be described below.
[0038]
First, the suspending means 3 has cantilevered two shafts 15 and 16 each having an open end, with the respective open end faces facing each other, and one cantilevered two shaft 16 can contact and separate its butted end. A traversing table 44 is arranged via traversing rails 43a and 43b (see FIG. 8) fastened to the main body frame 19 and slide nuts that are inserted and slid thereon, and the extension shaft is moved up and down on the table. A cantilevered biaxial shaft 16 having a slide member to be moved is attached, and the transverse cylinder 46 connected to the main body frame 19 can be expanded and contracted to be brought into and out of contact with each other.
[0039]
Further, the cantilevered two shafts 15 and 16 each having an open end are respectively composed of a main shaft 15a and an extension shaft 15b, and a main shaft 16a and an extension shaft 16b. The main shafts 15a and 16a are cantilevered by main shaft rotation bearings 21a and 21b. Slide tables 34a and 34b are fixed above the slide rails 35a and 35b, while the extension shafts 15b and 16b are cantilevered by the extension shaft rotation bearings 22a and 22b and are inserted into the slide rails 35a and 35b and slide. The ball screws 36a and 36b fixed on the side are rotated by drive motors 38a and 38b having shaft ends connected to each other, and nuts meshing with the motors are connected to the tables 34a and 34b. Can stretch.
[0040]
Also, as described above, the partition shaft 20 is prepared at all four positions of the open shaft end (see FIG. 4), so that the belt CS, B does not come off from the open shaft end, and the circumferential portion where the cut belt at the shaft end contacts. The center shaft 49 is swung from the outer shaft end to move the single shaft width when moving or mounting, removing it, etc. It is used properly to eliminate the stop function by swaying and accommodating the ridges y larger than the shaft diameter on the inner peripheral side of the belt between the spaces 15 and 16.
[0041]
In addition, the two opposing shafts 15 and 16 are brought into contact with each other and abutted against each other so that the partition rod 20 of the abutting portion accommodates the peak portion y portion of the collar larger than the shaft diameter within the belt circumference. As shown in FIG. 9, an arm 74 is attached to a sliding head 70 which can be supported and moved by a ball screw 72 having a linear rod 71 and a drive motor 73 installed on the shaft end from a rear end of the sleeve body CS. The pressing member 75 is applied to the sleeve CS, and the ring-shaped end face of the sleeve CS is evenly pressed so that the pressing movement can be performed by one width. At this time, the sleeve body CS hung on the main shafts 15a and 16a and one belt B are sandwiched between the pressing rolls 17a17b so that the cut belt CS does not ride on.
[0042]
Next, the wire aligning means 5 includes a turning table 53 that moves up and down the space between the two shafts 15 and 16 separated as shown in FIG. 7, and a core wire disposed along with the core wire cutting means 8 on the turning table 53. First, the wire pulling member 24 is swiveled to an upper position on the swivel table 53 so that the distance between the butted ends is set as a gap in which the core wire pulling member 24 can move up and down. The combined elevating ball screw is rotated forward and backward by a drive motor, and the amount of rotation is controlled to move up and down to a predetermined position.
[0043]
Next, the wire drawing means 6 includes a wire take-up shaft 25, a take-up shaft rotary bearing 64, a rotation drive motor 65, and the like, and an elevating slider 62 that raises and lowers them integrally, and the cutter means 18 moves up and down. The winding shaft 25 is positioned on the biaxial shaft center at the center position of the separation interval (S3) and fastened to the main body frame 19 so that the same amount of wire W can be pulled out from the left and right belt end faces. The amount of wire drawing can be controlled to a value obtained in advance by controlling the amount of rotation.
[0044]
As shown in FIG. 6, the winding shaft 25 has a front end portion of a trumpet shape so that the wire W can be reliably caught when it is lowered, and the wire W is wound without slipping in the split groove at the bottom.
[0045]
Subsequently, the wire cutting means 8 includes a cutter means 18, a turning table 53 on which the cutter means 18 is placed, an elevating table 52 for raising and lowering the cutter means 18, an elevating rail 55, an elevating ball screw 56, a drive motor 57, and the like.
[0046]
First, as described above, the cutter means 18 has the partition rod 20 shown in FIG. 6 (a) between two shafts formed by inserting the butt shaft ends 15 and 16 apart (S3) as shown in FIG. 6 is inserted and inserted from below, and the partition rod 20 shown in FIG. 6B is released and the guide claw 29 of the cutter 27 can be in direct contact with the side surface of the belt.
[0047]
Next, in the state where the belt side surface directly contacts the guide claw 29 of the cutter 27 in FIG. 6B and the root of the wire exposed portion is held on the belt side surface, a commercially available automatic nipper 28 is used along the belt side surface. Both ends of the stretched wire can be automatically cut at the same time.
[0048]
This cutter means 18 is configured to move up and down between the two butting shafts 15 and 16 that are in contact with and separated from each other, and is provided with a previous lifting mechanism, and this lifting mechanism is arranged on the turning table 53 on the lifting table 52. It is used in a configuration that can be switched and used together with the wire tension member 24. The adjustment of the pulling position of the wire pulling member 24 can be adjusted by the mounting position on the turntable.
[0049]
Subsequently, although not shown in FIG. 7, the belt take-out means 9 is suspended between the cantilevered two shafts 16 by removing the wire W in the previous belt removing process as described in the schematic diagram of FIG. Further, the single belt B can be pushed from the rear to the open end side, removed from the biaxial 16 and hooked on the swivel arm 32 to be taken out to the next step.
[0050]
It should be noted that the method of removing the core wire from the belt side surface and the removing device thereof according to the present invention are not necessarily limited to the embodiment shown in FIGS. 1 to 9 and may be modified as follows, for example. 1) Although the centering positioning of the exposed end of the core wire in FIG. 1 (d) is conducted by guiding it to the V-shaped groove g provided in the partition rod, the core wire led to the uppermost part or the lowermost part by pulling it. It is also possible to insert the guide claw by adjusting the distance between the two butted shafts and use the V groove m.
[0051]
