In general, there is known a cutting device including a rotating knife rotated by a motor and a stationary knife in sliding contact with the rotating knife, and a cleaning device for cleaning an adhesive molten material from a cutting object adhering to the rotating knife when the cutting object is cut between the rotating knife and the stationary knife (see patent document 1).

Problems to be solved by the invention
However, it is known that a sliding contact portion of the fixed blade, which is in sliding contact with the rotary blade, is at a high temperature due to friction, so that a molten material is hard to adhere to the sliding contact portion, and cleaning is not required. Therefore, in the cutting device in which the fixed blade is normally in sliding contact with the rotary blade, it is necessary to clean the molten material adhering to the rotary blade.
This is because, if the stationary blade is in normal sliding contact with the rotary blade, the molten material of the object to be cut that has been melted at the mutually sliding contact surfaces adheres to the surface of the rotary blade, and is cooled during the period until the next sliding contact with the stationary blade, so that the viscosity increases, and the molten material is repeatedly accumulated. At this time, if the deposit is deposited on the surface of the rotary knife, the gap between the fixed knife and the rotary knife is increased, and the sharpness of the cutting device is gradually deteriorated.
In this case, in the cutting device in which the fixed knife is normally in sliding contact with the rotary knife, if the cleaning function is present in the fixed knife itself, it is also conceivable to rely on the fixed knife for cleaning the rotary knife. At this time, the fixed knife is pressed by an urging member such as a leaf spring so as to normally come into sliding contact with the sliding contact surface of the rotary knife, and follows the fixed knife and the rotary knife without generating a gap therebetween. However, if the rotary knife vibrates during rotation due to its assembly accuracy or the like, the stationary knife makes bouncing contact with the sliding contact surface of the rotary knife during cutting of an object to be cut such as when the peripheral speed of the rotary knife increases, a gap is formed between the stationary knife and the rotary knife, and the following ability of the sliding contact surface of the stationary knife with respect to the rotary knife is reduced. Therefore, the molten material adhering to the rotary knife cannot be completely removed, and the cleaning effect is undeniably reduced even if the sharpness of the cutting device is not affected. In addition, the molten material at the time of cutting or after cutting is in a viscous state due to frictional heat, and even in a state where the gap between the both blades is small, it is difficult to scrape off the molten material by the fixed blade.
Further, in order to clean the molten material adhering to the rotary blade, it is conceivable to provide a dedicated cleaning device which does not depend on the fixed blade at a position near at least one of both ends of the reciprocating range of the rotary blade or at the holder, etc., but since the dedicated cleaning device is used, not only is the cost undeniable increased, but also a space for providing the cleaning device is required, and there is a concern that the cutting device will become larger.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a cutting device which does not require a cleaning device, is compact while achieving cost reduction, and can improve cleaning effects by improving followability of a sliding contact surface of a rotary knife with respect to a stationary knife, and efficiently removing molten material of the rotary knife, and a cloth folding machine including the same.
Means for solving the problems
In order to achieve the above object, the present invention provides a cutting device including a rotary blade rotated by a motor and a stationary blade normally brought into sliding contact with the rotary blade, the motor being controlled by a control means, wherein the control means has a function of cleaning a molten material of an object to be cut adhering to the rotary blade when the object to be cut is cut between the rotary blade and the stationary blade, and the control means controls the motor so that a peripheral speed of the rotary blade is set in a range of 15m/min to 150m/min lower than a peripheral speed of the object to be cut when the rotary blade is cleaned.
In addition, the control unit may be provided with a gap for stopping the driving of the motor when the rotary knife is cleaned.
Further, the control unit repeats setting of the interval during the cleaning of the rotary knife.
The present invention also provides a cloth folding machine including a cutting device, wherein the cutting device is the above-described cutting device.
In the above-described cloth folding machine including the cutting device, when a plurality of cloth materials are folded, the rotary knife is automatically cleaned between the cutting spans of the respective cloth materials which are cut in sequence.
[ Effect of the invention ]
In summary, when the motor is controlled so that the circumferential speed of the rotary knife is set to be in the range of 15m/min to 150m/min lower than the circumferential speed at the time of cutting the object to be cut during the cleaning of the rotary knife, the period of the vibration of the rotary knife due to the assembly accuracy of the rotary knife becomes much more abundant than that at the time of cutting the object to be cut during the cleaning of the rotary knife. Therefore, as in the case of cutting an object to be cut, there is no longer a case where the fixed knife makes contact with the sliding contact surface of the rotary knife so as to jump, and a gap is generated between the both knives. This increases the ability of the stationary blade to follow the sliding surface of the rotary blade during cleaning of the rotary blade, and the stationary blade smoothly slides on the sliding surface of the rotary blade, thereby efficiently removing the molten material adhering to the rotary blade during cleaning of the rotary blade and improving the cleaning effect. Further, since the peripheral speed of the rotary blade is kept low, the molten material adhering to the rotary blade tends to be hardened as compared with the molten material immediately after cutting, and the scraping effect by the fixed blade is improved.
Further, a cleaning device for cleaning the molten material adhering to the rotary blade is not required, and the cutting device can be made compact while reducing the cost.
Further, by providing an interval for stopping the driving of the motor at the time of cleaning the rotary knife, the vibration of the rotary knife becomes more sufficient than when the rotary knife is driven at a peripheral speed in the range of 15m/min to 150m/min, and a gap is less likely to be generated between the rotary knife and the fixed knife. This further increases the ability of the stationary blade to follow the sliding surface of the rotary blade during cleaning of the rotary blade, and the stationary blade smoothly slides on the sliding surface of the rotary blade, thereby efficiently removing the molten material adhering to the rotary blade and improving the cleaning effect.
Further, by repeating the interval at the time of cleaning the rotary knife, the vibration of the rotary knife becomes more sufficient than when the rotary knife is driven at a peripheral speed in the range of 15m/min to 150m/min, and a gap between the rotary knife and the fixed knife is less likely to be generated. This further increases the ability of the stationary blade to follow the sliding surface of the rotary blade during cleaning of the rotary blade, and the stationary blade smoothly slides or comes into close contact with the sliding surface of the rotary blade, thereby removing the molten material adhering to the rotary blade more efficiently and further improving the cleaning effect.
Further, since the cloth folding machine is provided with the cutting device, the molten material adhering to the rotary blade can be efficiently removed at the time of cutting the object to be cut which is cloth folded by the cloth folding machine, and the cleaning effect is improved.
Further, when a plurality of cloths are stacked, the rotary knife can be cleaned automatically between the cutting spans of the respective cloths that are cut sequentially, and the rotary knife can be cleaned efficiently using the cutting span of each cloth that is not cut by the rotary knife.

Detailed Description
In order to implement the mode of the invention
Embodiments of the present invention will be described below with reference to the drawings.
Fig. 1 is a perspective view of a cloth folding machine including a cutting device according to an embodiment of the present invention, and fig. 2 is a front view of a discharge opening of the cloth folding machine as viewed from the front.
In fig. 1 and 2, the cloth folding machine 1 includes a roll (not shown) in which an adhesive interlining S to be cut is wound into a roll shape, and a unwinding portion 11 for pulling out the adhesive interlining S from the roll. The cloth folding machine 1 further includes a cloth folding table 12 and a cloth folding machine main body 14, the cloth folding table 12 is horizontally disposed, the cloth folding machine main body 14 has a discharge port 13, the discharge port 13 is moved forward and backward between one side (right side in fig. 1) and the other side (left side in fig. 1) of the cloth folding table 12, and the adhesive interlining fabric S drawn out by the release portion 11 is discharged in a state where no wrinkles are formed.
The cloth folding machine main body 14 is provided with a guide rail 15 over the entire width direction thereof so as to face the discharge port 13. On this guide rail 15, a holder 16 that reciprocates along the guide rail 15 is provided. The holder 16 includes a cutting device 2 therein, has an inlet 161 (shown in fig. 3) at a lower end thereof for taking in the adhesive interlining fabric S when moving in and out from one side (right side in fig. 2) of the guide rail 15 to the other side (left side in fig. 2), and is configured to cut the adhesive interlining fabric S taken in from the inlet 161 from one side thereof by the cutting device 2.
The cloth folding machine 1 repeatedly performs the operation of moving the holder 16 in and out along the guide rail 15 to cut the adhesive interlining S by the cutting device 2 while moving the cloth folding machine main body 14 in and out to the other side of the cloth folding table 12 and moving it backward to the one side and discharging the adhesive interlining S of a desired length onto the cloth folding table 12 from the discharge port 13, and stacks the cut pieces S1 of the adhesive interlining S one by one on the cloth folding table 12.
Fig. 3 is a front view of the cutting device 2, and fig. 4 is a perspective view showing the vicinity of a sliding contact surface of the rotary blade 21 with respect to the fixed blade 22 of the cutting device 2. In fig. 3 and 4, the cutting device 2 includes a disk-shaped rotary knife 21 rotatably supported at the lower part of the holder 16 and integrally rotatably supported on a rotary shaft 211 protruding in the advancing and retreating direction of the cloth folding machine main body 14; and a block-shaped fixed knife 22 in which the fixed knife edge 221 is in normal sliding contact with the rotary knife 21. The rotary knife 21 is attached to the rotary shaft 211 located at the upper edge of the inlet 161 so that the rotary blade 212 faces the inlet 161, while the fixed knife 22 is provided at the lower edge of the inlet 161, and the follow-up property with respect to the contact surface of the rotary knife 21 is improved by the biasing force of a plate spring, not shown. The rotary blade 21 transmits the rotational force from the pulley 232 integrally rotatably supported by the shaft 231 of the motor 23 attached to the upper portion of the holder 16 to the rotary shaft 211 via the belt 24, and rotates in the direction of the arrow shown in fig. 3. Further, the motor 23 controls the amount of rotation by a command from a control device 25 as a control means. In this case, an AC motor having a simple structure and low cost can be applied as the motor 23.
Fig. 5 is a partially cut front view showing a state of adhesion of the molten material to the rotary blade 21 of the cutting device 2. In fig. 5, when the adhesive interlining fabric S is cut along the rotary blade 212 in the vicinity of the rotary blade 212 of the rotary knife 21, the molten material G from the adhesive interlining fabric S adheres thereto and accumulates in a ring shape with the passage of time. In this case, as the rotary knife 21, a rotary knife having a diameter of 100mm was used.
The control device 25 has a function of cleaning the molten material G of the rotary blade 21, as well as eliminating the accumulation of the molten material G in the vicinity of the rotary blade edge 212 of the rotary blade 21. Specifically, the controller 25 controls the motor 23 so that the peripheral speed of the rotary blade 21 is set to 47m/min lower than the peripheral speed (for example, 1410m/min) at the time of cutting the adhesive interlining fabric S when the molten material G adhering to the rotary blade 21 is cleaned. The motor 23 may be controlled by the controller 25 so that the peripheral speed of the rotary knife 21 during cleaning is set to be in the range of 15m/min to 150m/min, more preferably 30m/min to 100 m/min.
At this time, the cleaning operation of the rotary knife 21 by the control device 25 requires about 10 seconds, and after the adhesive interlining S is cut by the cutting device 2 of the holder 16 of the spreader 1, it also requires about 10 seconds until the next adhesive interlining S is spread and the cut of the spread adhesive interlining S is performed. Therefore, the controller 25 performs control such that the rotary blade 21 is automatically cleaned during a period of about 10 seconds between cutting spans of the respective adhesive interlinings S cut in sequence when the plurality of adhesive interlinings S are stacked.
The cleaning operation of the rotary knife 21 by the control device 25 is not limited to the interval between the cutting spans of the adhesive interlinings S cut in sequence when stacking a plurality of adhesive interlinings S, and may be performed by an operation of an operator at a time other than the time of cutting the adhesive interlining, or may be automatically performed based on a detection signal from a sensor for detecting the deposition state of the molten material in the vicinity of the rotary blade of the rotary knife, a measurement signal from a measurement unit for measuring the number of times of cutting the adhesive interlining by the cutting device, or the like. When the cleaning operation of the rotary knife is performed in accordance with another operation shorter than the above operation, the other operation shorter than the above operation may be set to stand by for a remaining time that offsets the time required for the cleaning operation.
In this way, since the motor 23 is controlled so that the circumferential speed of the rotary knife 21 is set to 47m/min lower than the circumferential speed at the time of cutting the adhesive interlining cloth S when the rotary knife 21 is cleaned, the period of vibration of the rotary knife 21 due to the assembly accuracy of the rotary knife 21 and the like when the rotary knife 21 is cleaned becomes much more abundant than that when the adhesive interlining cloth S is cut. Therefore, at the time of cutting the adhesive interlining fabric S, the fixed blade 22 may not be in contact with the sliding contact surface of the rotary blade 21 so as to jump, and a gap may be formed between the fixed blade 22 and the rotary blade 21. This increases the ability of the stationary blade 22 to follow the contact surface of the rotary blade 21 during cleaning of the rotary blade 21, and the stationary blade 22 smoothly slides on the contact surface of the rotary blade 21, thereby efficiently removing the molten material G adhering to the rotary blade 21 and improving the cleaning effect. Further, since the peripheral speed of the rotary blade 21 is kept low, the molten material G adhering to the rotary blade 21 tends to be hardened as compared with the case of cutting or after cutting, and the scraping effect by the fixed blade 22 is improved.
Further, a cleaning device for cleaning the molten material G adhering to the rotary blade 21 is not required, and the cutting device 2 can be made compact while reducing the cost.
Fig. 6 shows a control chart of the circumferential speed m/min of the rotary knife 21 with respect to the time T when the rotary knife 21 is cleaned.
As shown in the control chart of fig. 6, the controller 25 controls the motor 23 so that the peripheral speed of the rotary knife 21 is set to be lower than the peripheral speed of the adhesive interlining fabric S at the time of cleaning the rotary knife 21 (for example, 47m/min), and sets an interval Tb for stopping the driving of the motor 23 at this state, and sets the interval Tb to a length (for example, 1 second) sufficient to stop the rotation of the rotary knife 21. The controller 25 sets the interval Tb for stopping the driving of the motor 23 to repeat every predetermined time Ta (for example, 3 seconds) when the rotary knife 21 is cleaned.
At this time, when the motor 23 is stopped at the time of cleaning the rotary blade 21, even if the peripheral speed of the rotary blade 21 is lower than the peripheral speed at the time of cutting the adhesive interlining fabric S, the viscosity of the molten material G adhering to the rotary blade 21 is high because frictional heat is present as long as the peripheral speed exceeds 200 m/min. Therefore, in addition to the generation of the gap between the rotary blade 21 and the fixed blade 22, the following performance of the sliding contact surface of the fixed blade 22 with respect to the rotary blade 21 cannot be sufficiently expected at the time of cleaning the rotary blade 21, and it is difficult for the fixed blade 22 to smoothly slide in contact with the sliding contact surface of the rotary blade 21. In view of this, when the control device 25 cleans the rotary knife 21, the motor 23 needs to be controlled in advance so that the circumferential speed of the rotary knife 21 is set within the range of 15m/min to 150 m/min.
In this way, when the circumferential speed of the rotary knife 21 is lower than the circumferential speed at the time of cutting the adhesive interlining fabric S (for example, 47m/min) at the time of cleaning the rotary knife 21, the control device 25 sets the interval Tb for stopping the driving of the motor 23, and the interval Tb is set to a length sufficient to stop the rotation of the rotary knife 21, so that the period of the vibration of the rotary knife 21 at the time of cleaning the rotary knife 21 becomes more sufficient than when the circumferential speed is driven within the range of 15m/min to 150 m/min. When the motor 23 is restarted after a stop state, the stationary blade 22 is in close contact with the contact surface of the rotary blade 21. Accordingly, when the rotary blade 21 is cleaned, the rotary blade 21 starts to rotate from the state where the fixed blade 22 is in close contact with the contact surface of the rotary blade 21, and the molten material G in the rotary blade 21 can be more efficiently removed from the position where the molten material G is in close contact with the sliding contact surface, thereby further improving the cleaning effect.
Further, since the interval Tb for stopping the driving of the motor 23 is controlled to be repeated every predetermined time Ta (for example, 3 seconds) when the rotational speed of the rotary knife 21 is reduced during the cleaning of the rotary knife 21, the close contact of the fixed knife 22 with respect to the sliding contact surface of the rotary knife 21 is repeated during the cleaning of the rotary knife 21, and the molten material G in the rotary knife 21 can be removed more efficiently, and the cleaning effect can be further improved.
Further, since the cleaning operation of the rotary knife 21 by the control device 25 is automatically performed within approximately 10 seconds per cutting span of the plurality of adhesive interlining fabrics S, the cleaning operation of the rotary knife 21 can be smoothly performed without waiting time every time the plurality of adhesive interlining fabrics S are cut, and the work efficiency can be improved.
The present invention is not limited to the above embodiment, and includes various other modifications. For example, in the above embodiment, the interval Tb at which the driving of the motor 23 is stopped at the time of cleaning the rotary knife 21 is set to a length sufficient to stop the rotation of the rotary knife 21 (the time Tb is 1 second), but it may be set only such that the rotary knife is set to a peripheral speed lower than the peripheral speed at the time of cutting the adhesive backing cloth (for example, about 47m/min) at the time of cleaning the rotary knife.
Further, the interval at which the driving of the motor is stopped may be set to a length that is insufficient to stop the rotation of the rotary knife when the circumferential speed of the rotary knife is set to be lower than the circumferential speed at the time of cutting the adhesive interlining fabric S. In this case, since the period of the vibration of the rotary knife during the cleaning of the rotary knife is sufficient when the rotary knife is driven at a peripheral speed in the range of 15m/min to 150m/min, the sliding contact surface of the fixed knife with respect to the rotary knife is easily adhered. Therefore, when the rotary knife is cleaned, the rotary knife starts to rotate from a state that the sliding contact surface of the fixed knife relative to the rotary knife is easy to cling, the molten substance of the rotary knife can be effectively removed from the position clinging to the sliding contact surface, and the cleaning effect can be further improved.
In the above-described embodiment, the adhesive interlining is used as the object to be cut, but the object to be cut is not limited thereto, and may be, for example, an object to be cut such as a resin material.
In the above embodiment, the interval Tb for stopping the driving of the motor 23 is controlled so as to be repeated once every predetermined time Ta (for example, 3 seconds) when the peripheral speed of the rotary blade 21 is lower than the peripheral speed at the time of cutting the adhesive interlining cloth S at the time of cleaning the rotary blade 21, but may be controlled so as to be performed only once when the peripheral speed of the rotary blade 21 is lower than the peripheral speed at the time of cutting the adhesive interlining cloth.
In the above embodiment, the AC motor is applied as the motor 23, but a servo motor having high low-speed driving capability may be applied. The AC motor, if selected in accordance with the high-speed rotation at the time of the interruption, is undeniably low in the ability to drive at the low speed, but by controlling the interval Tb at which the driving of the motor 23 is stopped so as to be repeated once every predetermined time Ta (for example, 3 seconds), it is possible to compensate for the low ability at the time of the low-speed driving, and effectively utilize the advantage of the low-cost AC motor.
Further, although the above embodiment has been described with respect to the case where the cutting device is used in a cloth folding machine, it is needless to say that all the devices using the cutting device are all targets as long as the cutting device includes a rotary knife rotated by a motor controlled by a control unit and a fixed knife in sliding contact with the rotary knife.
