[0015]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a cutting device and a cutting method for a transmission belt sleeve according to the present invention will be described with reference to FIGS. FIG. 1 is an overall configuration diagram of a transmission belt sleeve cutting device of the present invention, and FIG. 2 is a conceptual diagram showing a groove position detection method of the present invention. First, as shown in FIG. 1, the transmission belt sleeve cutting device 1 comprises a sleeve rotating means 3, a cutter moving means 5 that moves in a direction perpendicular to the rotating shaft 4, and a cutter means 7. In the present invention, in the cutter moving means 5, the correction control means for finely adjusting the difference in the position of the cutter blade 31 by detecting the difference from the actual groove position by using the groove position detecting means 8 whose cut positioning is a contact type. 10.
[0016]
Next, a partial perspective view of the belt sleeve BS to be cut in the present invention is shown in FIG. 5, and the belt sleeve has a plurality of grooves extending in the width direction over the entire circumference of at least the outer circumferential surface of the inner and outer circumferential surfaces thereof. There are transmission belts such as (a) a V-ribbed belt, (b) a double V-ribbed belt, and (c) a multiple-hanging low-edge belt.
[0017]
First, (a) the V-ribbed belt is a transmission belt formed by alternately arranging trapezoidal peaks RR and V-shaped grooves M on one side at a predetermined pitch in the width direction, and the flat back side is in contact with the rotating shaft. (B) The double V-ribbed belt is a transmission belt in which the aforementioned peak portion RR and groove portion M are arranged on both sides at a predetermined pitch in the width direction, and on the outer surface of the rotating shaft, there is a sleeve peak portion RR and groove portion. The crests and grooves formed by reversing M are engraved. (C) The multi-row low-edge belt has a plurality of trapezoidal peaks RR and V-shaped belts by joining the backs of a plurality of belts with canvas or the like. It is a transmission belt in which grooves M are arranged in the width direction. As in (a), it is turned over and hung on a rotating shaft. In this figure, a corrugated cog C is represented on the trapezoidal mountain bottom, but this bottom is smooth. Can be used with any type.
[0018]
Next, each part of the transmission belt sleeve cutting device 1 according to the present invention will be described with reference to FIGS. First, the cutter moving means 5 according to the present invention has a function of two-dimensional movement in a direction parallel to the rotating shaft 4 (in the direction XX in FIG. 1) and a direction perpendicular to the direction (in the direction Y in FIG. 1). In particular, the movement in the parallel direction according to the present invention has a function of determining the belt width by the parallel movement first, and then determining the belt width. Next, the movement in the perpendicular direction is opposed to the running surface of the belt sleeve BS. Then, the cutter blade 14 is pressed against the running belt sleeve BS and cut to cut the rotating sleeve.
[0019]
Subsequently, the parallel movement control is composed of setting control and correction control. First, regarding the setting control, each cutting condition is stored in advance according to the type of the belt sleeve BS to be cut and stored in a database. If the belt sleeve type is input at the start of cutting, the cutting blade 14 is automatically operated from the standby position to the cutting position of the running belt sleeve BS so that the memory condition can be extracted and the ring can be cut to a predetermined width. The system is a program-controlled system and its operation will be described later in the operation flow.
[0020]
Next, with regard to correction control for determining the final position of the cut, the cutter blade 14 is moved and positioned to the program position determined in advance by the above-described setting control, and in addition, it is opposed to the rotating belt sleeve BS. The position of the cutter blade 14 is corrected according to the actual product by measuring the difference δ (see FIG. 2) with respect to the previous set position by detecting the peak position, and the groove position detecting means 8 and correction control means 10.
[0021]
First, as shown in FIG. 2, the groove position detection means 8 is parallel to the belt sleeve BS on the rotating shaft 4 and moves in the axial direction so as to contact the groove portion M of the running belt sleeve to detect the groove position. The rotating body 12 having a plurality of peak portions R fitted to the groove portion M is provided as a contact body. As shown in FIG. 1, the configuration includes a detection mechanism 16, a measurement sensor 17, and a detection movement mechanism 18.
[0022]
First, the detection mechanism 16 includes a detection roll 26 having three peak portions R as a rotating body 12 fitted in the groove portion M of the belt sleeve BS and a support frame that pivotally supports the rotating body 12 so as to be laterally displaced. The slide unit 22 is connected to the slide rail end. As shown in FIG. 2, the detection roll 26 is cut so that the peak portion R that fits in the belt groove portion M processed on the surface of the belt sleeve BS that rotates on the shaft is convex on the outer periphery of the detection roll. The belt sleeve is provided in accordance with the groove shape of the belt sleeve.
[0023]
First, the detection roll 26 is first set and controlled so as to be translated in the vicinity of the groove of the cut portion of the sleeve and set to the upper position in FIG. 2, approaching the groove in the right angle direction along the groove slope R. The lateral displacement amount is δ in FIG. 2, and the difference δ is corrected at the cutter position.
[0024]
Next, the support frame is composed of a U-shaped support member 24 and a sliding rod 41 provided in the horizontal direction between the support members, and a detection roll 26 is inserted into this rod so that the detection roll 26 can be freely moved sideways. In addition, it is pivotally supported around the rod 41 so that it can be displaced.
[0025]
Note that a mechanism for maintaining the lateral origin position is provided for the mechanism that allows the lateral displacement of the detection roll 26, and this is a thrust that rotates and slides against both end faces of the rotating detection roll 26 shown in FIG. The mechanism is such that the detection roll is clamped from both ends by a reference position cylinder 43 and a pressing cylinder 45 provided at both ends of the support member with the bearing interposed therebetween, whereby the detection roll 26 held at the horizontal origin position is rotated. The peak portion R of the detection roll 26 is pressed against the groove M of the moving belt sleeve BS by the following moving mechanism 18, and the lateral shift (difference δ) generated at that time is absorbed by the shift movement of the detection roll 26. I can do it.
[0026]
Next, the measuring sensor 17 uses a meter that can press the peak portion R of the detection roll 26 against the groove portion M of the belt sleeve BS, measure the lateral displacement amount δ of the detection roll 26 generated at that time, and output electric power. It is a commercially available linear gauge. The lateral displacement is measured at the non-rotating portion at the front end of the pressing cylinder while avoiding direct contact with the rotating portion at the front end of the gauge.
[0027]
Next, the detection moving mechanism 18 includes a linear rail, a linear head with a built-in linear bearing and gripping the linear rail, a servo motor attached to the end of the linear rail, and a ball screw connected to the rotating shaft to linearly rotate the rotation. A commercially available slide unit is used which is composed of a drive device that replaces the movement, and in FIG. 1 the detection roll slide unit 21 is used for movement in the X direction, and the detection roll slide unit 22 is used for movement in the Y direction. The linear head of the Y direction slide unit 22 is connected to the linear head of the X direction slide unit 21. By this movement in the X and Y directions, the detection roll 26 can move parallel to and away from the rotating shaft of the rotating belt sleeve (these operations will be described later).
[0028]
Next, the correction control means 10 uses the positioning controller 11 on the basis of the electrical signal of the lateral deviation amount measured and electrically output by the detection moving mechanism 18 described above, and determines the cutter blade position according to the lateral deviation amount. The control system is shown in the block diagram of FIG.
[0029]
First, the detection roll 26 is installed in such a manner that the detection detection portion of the measurement sensor 17 is pressed against the front end portion of the pressing cylinder 45 provided so as to be in contact with and sandwiched between both end faces of the detection roll 26 and the detection roll 26 is displaced laterally. Accordingly, the detector is arranged so that it can be measured by expanding and contracting.
[0030]
Next, in the correction control flow, the amount of lateral deviation of the detection roll 26 is detected by the measurement sensor 17 that measures the amount of lateral displacement by making contact with a detection end that can be expanded and contracted, and the signal is converted through a linear gauge counter for positioning. Input to the input unit of the controller 11 and the input lateral shift amount is arithmetically converted into positioning data as a correction amount by the CPU unit in the controller 11, and the correction amount is converted into pulse output by the positioning unit, and the number of pulses Accordingly, the servo motor SM1 is rotated via the servo amplifier, and the X-direction slide unit 47 is moved to accurately correct the lateral displacement detected by the detection roll 26.
[0031]
Subsequently, the cutter means 7 for cutting the belt sleeve BS is known to be processed with a single blade, and here, a two-blade according to the present invention will be described with reference to FIG. First, it protrudes on the moving table 35, and is composed of a fixed blade 31 and a movable blade 32 provided with a blade interval moving mechanism 33, whereby the interval between the two blades can be adjusted. The configuration of the cutter means 7 includes two cutter blades 14, a cutter holder 36, an inter-blade setting mechanism 33, and a cutter moving table 35.
[0032]
First, the cutter blade 14 is composed of two round blades, each fixed to a cutter holder, and the disk surfaces of the round blades are aligned parallel to the right-angle cross section of the shaft so that the two round blades are parallel to each other. The fixed blade 31 is mounted on the cutter moving table 35 via the cutter holder 36 and the movable blade 32 is mounted on the cutter moving table 35 so as to be movable using the blade interval setting mechanism 33. The cutter holder 36 is used.
[0033]
The blade interval setting mechanism 33 of the movable blade 32 uses a commercially available integrated actuator 38 in which a linear guide, a ball screw, a movable head 54 and a servo motor 55 are integrated in a compact manner. In this way, the movable blade 32 which is the other blade facing the fixed blade 31 can be moved in the distance to adjust the blade interval.
[0034]
Note that the setting position relationship between the detection roll 26 and the two-blade composed of the fixed blade 31 and the movable blade 32 is shown in FIG. 2 when the cut width is composed of three peaks RR. In the drawing, the two ridges R can be fitted between the groove into which the movable blade 32 cuts with reference to the groove position where the fixed blade 31 will cut into the four grooves M of the belt sleeve. These grooves are arranged so that they can always be detected. If the cut width becomes wider and the number of ridges further increases, the number of detection roll ridges can be increased.
[0035]
Next, with respect to the sleeve rotation means 3, as shown in FIG. 7, a cylindrical belt sleeve BS having a plurality of grooves extending in the width direction is stretched around a rotation shaft 4 including a main shaft 63 and a driven shaft 65. Then, the crest portion R of the guide roll 67 can be prevented from being meandered by fitting the crest portion R of the guide roll 67 into the groove portion M of the belt sleeve BS that is rotated on the main shaft by the guide roll 67 with a crest disposed close to the main shaft 63. A meandering prevention mechanism 61 is used.
[0036]
Next, a method for cutting the transmission belt sleeve using the cutting device 1 having the above configuration will be described with reference to the flowchart shown in FIG. First, in the sleeve insertion (S11), the belt sleeve BS is inserted into a shaft mounting mechanism composed of a cantilevered main shaft 63 and a driven shaft 65 that are open on the front side (see FIG. 7). Next, the cutting conditions are input and in automatic start (S12), the belt type, belt pitch circumference and the like are input to the touch panel and the start button is pressed.
[0037]
In the sleeve extension (S13), the tailstock, which is a shaft support mechanism capable of opening and closing the shafts, is closed to support both ends, and the driven shaft is separated to widen the distance between the two axes. Then, the belt sleeve is extended and then the sleeve travels (S14), and on the other hand, the movable blade 32 is servo-controlled by the integral actuator in the blade interval setting (S13 '), and the interval between the two blades is set to a predetermined value. Then, the groove detection roll / cutter blade moves laterally to the N-th cut position (S15), and the groove detection roll / cutter blade moves two-dimensionally in the X and Y directions from the position where the groove detection roll / cutter blade is retracted and waits. Control moves to the first cut position and the next cut position: yes / no? Wait for the command of (S21).
[0038]
On the other hand, after the sleeve travel (S14), the travel preparation is completed: Y / N? If (S15 ′) is NO, the sleeve travel (S14) is continued, and if YES, the groove roll lowering (S16) is activated and the groove roll provided with three crests on the groove of the belt sleeve is lowered and pressed. Fit mountains and grooves. Next, in the groove roll displacement measurement (S17), the lateral displacement difference at the time of fitting is detected and measured by the displacement output of the linear gauge.
[0039]
Next, the groove roll rise (S18) waits for the movement to the next cut position where the groove roll whose measurement has been finished is retreated upward and is repeatedly repeatedly cut. Next, in the cutter blade position correction (S19), the positioning controller servo-controls the cutter moving slide unit according to the measured displacement amount of the groove roll, and performs correction control to the previously set control position, thereby cutting accurately. The position can be determined.
[0040]
On the other hand, the main shaft is driven and rotated by the sleeve travel (S14) and starts rotating around the free driven shaft, and the guide roll with a crest is pressed against the grooved belt sleeve to rotate the rotating belt sleeve. On the other hand, the cutting operation (S20) is entered, and the cutter moving Y-direction slide unit 48 is operated to push the cutter blade into the rotating belt sleeve and rotate it around to rotate the belt sleeve. Thus, one belt having a predetermined width is obtained.
[0041]
Hereinafter, next cut position: presence / absence? In (S21), it is determined whether there is no remaining cut by repeating, and the cumulative number of cuts is compared and calculated from the set number of cuts. If there is a remaining, it is repeated again to move to the Nth cut position (S15) and return to N with the groove roll. Measure the first cut position and repeat the cutter blade position correction to sequentially cut the ring.
[0042]
Eventually, there is no remaining cutting, and the process moves to the sleeve travel stop (S22) and stops traveling. On the other hand, when the groove detection roll / cutter blade moves to the origin position (S22 ′), the groove detection roll / cutter blade moves to the retracted position. To enter standby mode. Next, in the cut belt release (S23), the reverse operation of the above-mentioned sleeve extension (S13) is performed, the distance between the two axes is reduced, the tail stock of each axis of the both-end support is opened, and the cantilever state is restored. Removal (S24), that is, the belt sleeve that has been cut in a circle and cut for each belt is removed from the shaft mounting means, and the process proceeds to cutting of the next new belt sleeve. Thus, the width of one sleeve is cut and repeated.
[0043]
Next, the narrow cut concerning this invention is demonstrated using FIG. (B) W1 in the figure indicates the standard cut width, and the belt width is increased by increasing the number of the belt crests R to 3 and 4 with the center of the groove of the belt sleeve BS as the belt width end, thereby increasing the transmission horsepower. More selected. Next, the cut width indicated by W2 in the figure is a narrow cut, and the cut positions on both end faces of the belt are cut into the belt inside from the center of the groove compared to the above, that is, without leaving the arc portion of the groove bottom. In fact, it is cut narrowly.
[0044]
In this way, in order to cut narrowly, if one cutter blade is to be cut sequentially, the thickness between N1 and N2, N3 and N4, and N5 and N6 in the figure is approximately 0.3 mm (rib pitch 3.56). It is necessary to make a sliced slice of a ring with a 6 mm rib rib, etc., and it is difficult to make the thin wall width uniform by cutting with a single blade. It has been.
[0045]
The widths of the two cutter blades are set to N2 and N3 and N4 and N5 in FIG. 4 (b), respectively, and as shown in FIG. The width is cut while adjusting the pressure due to the blade thickness at the time of cutting to balance the left and right and sandwiching the cut belt between the two blades to ensure a uniform width. In such two-blade positioning, the groove position of the above-described belt sleeve is accurately detected and corrected, and the contact of the left and right cutting blades 31 and 32 with the crest R is maintained on the left and right sides, preferably. A narrow cut with excellent accuracy can be made.
[0046]
Moreover, the shape of the inner surface side of the left and right blades is a single-stage Shinogi, the Shinogi angle θ1 is 5 to 10 °, and the Shinogi thickness T1 is 0.02 to 0.1 mm. In this way, the left and right cutting edges bite into the belt sleeve BS and receive compression corresponding to the thickness of the cypress, and the left and right are balanced to prevent lateral deviation. The shape of the left and right blades on the outer surface side is a two-stage cypress, and the first tier of the blade edge has a cynogi angle θ2 equivalent to the inner surface of 5 to 20 ° and a shino thickness T2 of 0.15 to 0.25 mm and two tiers. The eyes have a cynogi angle θ3 of 3 to 10 ° and a blade thickness T3 of 0.5 to 2.5 mm.
[0047]
Note that the transmission belt sleeve cutting device and the cutting method thereof according to the present invention are not limited to those shown in FIGS. 1 to 8, and may take the following forms, for example.
1) The sleeve rotating means 3 is not necessarily limited to the one that is pivoted between the main shaft 61 and the driven shaft 65 of this example. For example, at least one of the main shaft 61 and the driven shaft 65 is one axis. The groove position can also be suitably used by correcting the groove position using the detection roll.
[0048]
2) In this example, the setting control and the correction control are divided and explained for the sake of convenience in the additional correction control means for the improved machine.
[0049]
3) About the groove | channel over a perimeter, it is not necessarily limited to a continuous mountain, About the groove shape which can be guided across the discontinuous mountain, it can implement similarly to a present Example.
4) In the present embodiment, the cutter for detecting and correcting the groove position is only the fixed blade 31 and the position of the movable blade 32 is not directly detected. However, the detection roll unit is divided into left and right, and the measurement sensor is installed. It can be implemented in the same way by expanding.
[0050]
【The invention's effect】
In the configuration according to claim 1, since the mechanism portion can be taken in with a simple mechanism instead of the high-precision and expensive electronic image means, the mechanism is inexpensive and the maintenance cost is low, and in addition, the measurement reliability is high. Since the cutter positioning can be performed accurately and easily, the effect of improving the productivity can be obtained.
[0051]
In the configuration according to claim 2, since it is possible to measure the amount of lateral deviation with a small variation with respect to a plurality of grooves as detection targets, the variation in the belt width cut performed by correcting the cut position based on the measurement result is reduced, and the quality is reduced. Has the effect of improving.
[0052]
In the configuration according to claim 3, a belt having particularly high cut width accuracy can be obtained with a cut width sandwiched between two blades. Therefore, the belt end surface is cut at a mountain slope portion with a belt having at least one mountain or the like. It is possible to cut such a narrow cut with high accuracy.
[0053]
In the method according to claim 4, the detection body is circumscribed, the detection mechanism is taken in and direct measurement is possible, and a simple and highly reliable apparatus can be realized, which can improve productivity in the quality and cost of the cutting process. There is an effect.

In the method according to the fifth aspect, the accuracy of the installation position of the cutter blade is high with respect to the groove position of the belt sleeve, and in addition, since the cutting can be performed with the belt width sandwiched by two cutting blades, variations in the cutting width can be ignored. Since high-performance cutting is possible in this way, there is an effect that it is possible to cope with a narrow cut product in which both end portions of the belt width cut the slope hem of the groove portion.
[0055]
