2. Description of the Related Art Conventionally, there are known two types of cutting devices in which a material to be cut is different in a mechanism for feeding a material depending on different materials of a roll material and a sheet material. For example, in the case of a cutting device that cuts a sheet material, the sheet is placed on a table and moved along with the table. As shown in FIG. And a ball screw 9 provided between the moving table 4 and the stationary platen 3 for reciprocating the moving table 4 with respect to the stationary platen 3 by a rotational driving force. And a servo motor 5 that rotates the ball screw 9 forward and backward. The sheet-like material to be cut M1 is placed on the contact plate 2 and positioned, sent to the movable platen 6 side by the rotational drive of the servo motor 5, cut (cut or trimmed), and sent back to its original position after cutting. It is like that.
[0004]
Further, in the case of a cutting device that cuts the roll material M2, it is sent while being sandwiched between upper and lower rollers. As shown in FIG. 9, the transport mechanism is a roll-shaped material M2 on the stationary platen 3. A roll feeder 7 having upper and lower rollers 7A and 7B that hold the roller, and a roll feeder drive mechanism (servo motor) 8 that rotates the rollers 7A and 7B to feed the roll-shaped workpiece M2 to the movable platen 6 side.

A backing plate 2 is placed on the stationary platen 3 below the movable platen 6, and the roll-shaped workpiece M <b> 2 is cut (cut or trimmed) on the backing plate 2. Instead of the backing plate 2, it may be sent out to the movable platen 6 side in a state where the backing plate 19 is attached to the lower surface of the roll-shaped material to be cut M 2 in advance.
[0005]
As described above, in a conventional cutting apparatus, when a material to be cut is cut, that is, cut (cut) or die-cut (trimmed), a sheet-like material is fed onto a moving table as a mechanism for feeding the material to be cut. There are a mechanism for placing and feeding a cutting material and a mechanism for feeding a roll-shaped material to be cut by a pair of rolls using a roll feeder, and it is necessary to install separate machines according to these feeding mechanisms. For this reason, the present inventors have already proposed a cutting device that sandwiches a contact plate on which a sheet-like material to be cut is placed between a pair of rollers of a roll feeder in order to share the model (Patent Document 2). reference). In this cutting apparatus, when cutting a roll-shaped material to be cut, the backing plate is removed from the roll feeder, the roll-shaped material to be cut is sandwiched between the roll feeders and sent to the movable platen, and the sheet-shaped material to be cut is cut. In this case, the sheet-shaped material to be cut is positioned and placed on the backing plate, and the backing plate on which the material to be cut is placed is sandwiched between a pair of rollers and sent to the movable platen by the roll feeder.

[Problems to be solved by the invention]
In the conventional cutting apparatus according to the above configuration, the contact plate on which the material to be cut is placed is sandwiched between a pair of rollers so as to be sent out to the movable platen by the roll feeder, so in order to ensure accurate machining accuracy Therefore, there is a problem that positioning of the material to be cut with respect to the roller must be performed accurately, and the positioning work is troublesome. Further, since the contact plate on which the material to be cut is placed is sandwiched between a pair of rollers and sent out, the material of the material to be cut causes the contact plate and the material to be cut to slide on the fixed platen. However, there is a problem that the processing accuracy is affected by meandering or skewing. Further, since the material is sandwiched between the rollers and sent out, there is a problem that the material cannot be used for a material to be cut (for example, a material in which a medicine is sealed).
[0008]
The present invention has been made in order to eliminate the above-mentioned drawbacks, and it is possible to use a single cutting device of different types depending on the material with a simple configuration, to improve processing accuracy, and to the material of the material to be cut.

  In the cutting device according to the present invention, a fixed platen on which a material to be cut is placed, a movable plate provided above the fixed platen, and a blade type attached to the lower side in a replaceable manner, and the cut on the fixed platen In a cutting apparatus having a feeding means for moving the material and feeding it below the movable platen, the feeding means is disposed above the lower roller and the lower roller whose upper end surface substantially matches the upper surface of the fixed platen. A roll feeder that holds the material to be cut between the upper and lower rollers, a drive mechanism that drives the upper and lower rollers of the roll feeder forward and backward by a drive system, and an upper shaft of the roll feeder that moves the movable shaft. And a lifting mechanism that moves up and down via a pivot support member, and a table that is detachably disposed between the upper and lower rollers and that is connected to the drive system and moves on the stationary platen.In addition, a feed gear is provided on the movable shaft of the upper roller, and a collar having a flange formed on the outer peripheral surface is provided on the shaft of the lower roller so as to face the feed gear. Is provided with a rack guide disposed on the inner side of the collar collar and formed with rack teeth meshing with the feed gear on the upper surface.Thus, when the material to be cut is a sheet-like member, first, the sheet-like material to be cut is placed on the table via a backing plate, the upper roller of the clamping mechanism is raised by the lifting mechanism, and the front end of the table in the feeding direction Is arranged between the upper and lower rollers, and this table is connected to the drive system of the drive mechanism. When the drive system of the drive mechanism is driven in the forward direction, the upper and lower rollers are driven in the feeding direction, the table moves on the fixed platen to the movable platen side, and the sheet-like material to be cut placed on the table by the movable platen Is cut. After cutting, when the operation of the movable plate is stopped and the drive system of the drive mechanism is driven in the opposite direction by the same amount, the upper and lower rollers are driven in the feed-back direction, and the table returns to the original position. When the material to be cut is a roll-shaped member, the table is removed from the roller, the delivery end of the roll-shaped material to be cut is sandwiched between the upper and lower rollers, and the drive system is driven in the forward direction. Since it is driven, the roll-shaped material to be cut is sent to the movable platen side and cut. For this reason, it can combine with the cutting of the to-be-cut material from which a kind differs with one machine. Further, since the lower surface of the table can be moved on the fixed platen and sent to the movable platen side can be sent back, the moving table can have a simple configuration. In addition, since the upper roller can be held on the material to be cut and the table can be moved, even the material to be cut that cannot be sandwiched can be sent without being restricted by the material of the material to be cut. , The degree of freedom of processing is improved. In addition, since the material to be cut is supported by the table via the contact plate, it is sent to the movable platen side and cut, so that more accurate processing accuracy can be achieved compared to the case of using only the contact plate as in the past. Can be secured.Furthermore, since the rack guides on both sides are restricted in displacement in the width direction by the locking portions, the material to be cut is fed out linearly integrally with the table. For this reason, the material to be cut does not meander or skew.
[0015]
  Claim2In the cutting device according to the present invention, a circumferential groove for receiving the feeding gear is formed on the outer peripheral surface of the collar so that the feeding gear and the collar do not interfere with each other when the upper roller is at the lowest position.
[0016]
  Claim2In the cutting apparatus according to the present invention, when the upper roller is at the lowest position, the upper roller is at the lowermost position by forming a circumferential groove on the outer peripheral surface of the collar so as not to interfere with each other. Even if the gap between the upper and lower rollers is close to zero, the feed gear and collar do not interfere with each other, so it is possible to cut even very thin workpieces with or without a table. There is no need to limit the type of material to be cut. Further, since the feed gear and the collar can be arranged in the vicinity of both ends of the upper and lower rollers, the apparatus can be reduced in size. Furthermore, the width of the table can be made shorter than the effective minimum width, and the weight can be reduced.
[0017]

[0022]
As shown in FIG. 4, a servo motor 21 is connected to the drive shaft 22 of the lower roller 16A. The servo motor 21 is configured to drive the lower roller 16A to rotate forward and backward. Drive gears 24 </ b> A and 24 </ b> B are attached to both sides of the drive shaft 22. As shown in FIG. 6, the first idler gears 25A and 25B attached to the fixing pin 25C are engaged with the drive gears 24A and 24B, respectively. The first idler gears 25A and 25B are engaged with the second idler gears 27A and 27B, respectively, and the first and second idler gears 25A-27A and 25B-27B connect the shafts 25C and 27C to each other. First links 26A and 26B are attached. The second idler gears 27A and 27B mesh with driven gears 29A and 29B attached to the movable shaft 23 of the upper roller 16B, respectively. Between the second idler gear and the driven gear, the second links 28A and 28B are attached to the shafts 27C and 23 with the shafts 27C and 23 connected to each other.
[0023]
Thus, the drive system of the drive mechanism 30 includes the servo motor 21, the drive shaft 22, the drive gears 24A and 24B, the first idler gears 25A and 25B, the second idler gears 27A and 27B, the driven gears 29A and 29B, and the movable shaft. 23. Therefore, when the servo motor 21 is driven to rotate, the rotation of the drive shaft 22 is transmitted to the driven gears 29A and 29B via the idler gears 25A to 27A and 25B to 27B, and the upper roller 16B is connected to the lower roller 16A. It is designed to rotate in the reverse direction. When the upper roller 16B is displaced upward by the air cylinders 31, 31, only the second idler gears 27A, 27B are driven gears 29A according to the movement of the second links 28A, 28B and the first links 26A, 26B. , 29B and the first idler gears 25A, 25B while being engaged and displaced following the driven gears 29A, 29B, the rotational driving force from the servo motor 21 is always transmitted to the movable shaft 23 of the upper roller 16B. Yes.
[0024]
The upper roller 16B is moved up and down by the air cylinder 31, and is displaced in the vertical direction according to the material of the material to be cut M2, so that a predetermined pressing force can be applied by the material of the material to be cut M2. It has become. When the upper roller 16B rises and is held at the upper non-clamping position, a gap is formed between the upper and lower rollers 16A and 16B. When the upper roller 16B is lowered while the roll material M2 and the contact plate 19 are inserted into the gap, the roll material M2 and the contact plate 19 are sandwiched between the upper and lower rollers 16A and 16B.
[0025]
Incidentally, as shown in FIGS. 4, 5, and 7, delivery gears 40A and 40B are attached to the movable shaft 23 of the upper roller 16B in the vicinity of both end portions of the upper roller 16B. Collars 41A and 41B are attached to the drive shaft 22 of the lower roller 16A so as to face the feed gears 40A and 40B. The collars 41A and 41B are formed with a circumferential groove 42A that is recessed in the outer peripheral surface, and a collar portion (locking portion) 42B that protrudes outward in the width direction. The feed gears 40A and 40B and the collars 41A and 41B are arranged so that when the upper roller 16B is at the lowest position, for example, when the upper roller 16B is lowered to a position where it contacts the lower roller 16A, the circumference of the collars 41A and 41B The teeth of the feed gears 40A and 40B are received in the groove 42A, and do not interfere with each other. That is, in the present embodiment, the outer diameters of the feed gears 40A and 40B substantially match the outer diameter of the upper roller 16B or are formed to be slightly larger. Even if the diameters of the feed gears 40A and 40B are larger than the outer diameter of the upper roller 16B, the teeth of the feed gears 40A and 40B are accommodated with play in the circumferential grooves 42A of the collars 41A and 41B. It has become.
[0026]
Between these feed gears 40A, 40B and the collars 41A, 41B, as shown in FIGS. 4, 5, and 7, a plate-shaped synthetic resin table 50 is mounted. Bar-shaped rack guides 51A and 51B are attached to both ends of the table 50 in the width direction. The rack guides 51A and 51B are formed with rack teeth 52A and 52B meshing with the feed gears 40A and 40B on the upper surface. The rack guides 51A and 51B are attached to the table 50 via L-shaped metal fittings 53A and 53B. The L-shaped brackets 53A and 53B are attached to the rack guides 51A and 51B from the lower surface of the table 50 with a countersunk screw (not shown). On this table 50, a backing plate 2 (see FIG. 8) and a sheet-like material to be cut M1 (see FIG. 8, hereinafter, the sheet-like material to be cut M1 is referred to as a sheet material M1) which are respectively cut into predetermined vertical and horizontal dimensions. ) Is placed. The contact plate 2 and the sheet material M1 are positioned on the table 50 by an adhesive tape. The contact plate 2 prevents the blade from being damaged, and the blade is inserted into the inside of the material to be cut, and is made of, for example, a film material such as a laminate film or a synthetic resin material.
[0027]
In the table 50 having rack guides 51A and 51B at both ends in the width direction, when the upper roller 16B is lifted by the air cylinder 31 and held upward, the front end in the feed direction is formed between the upper and lower rollers 16A and 16B. It is inserted into the gap. The table 50 is configured such that the outer surfaces of the L-shaped brackets 53A and 53B at the front end in the feeding direction come into contact with the inner surfaces of the flange portions 42B and 42B, and the upper roller 16B is lowered. The rack teeth 52A and 52B are meshed with the feed gears 40A and 40B. For this reason, when the roll feeder 16 is rotationally driven by the driving mechanism 30, the rack guides 51A and 51B are guided by the collars 41A and 41B in the delivery direction in accordance with the rotation of the delivery gears 40A and 40B, and linearly move. 50, the displacement in the width direction is restricted between the flanges 42B and 42B, and the upper surface of the fixed platen 13 slides linearly between the rollers 16A and 16B. For this reason, if the feed direction distance of the table 50 is inputted to the drive control device 17 in advance, and the rollers 16A and 16B are set to be reversed by the feed direction distance after the cutting by the movable platen 14, the table 50 is It is designed to return to the original position. When the upper roller 16B is lowered and the rack teeth 52A, 52B are engaged with the feed gears 40A, 40B, as shown in FIG. 4, a predetermined gap is provided between the upper and lower rollers 16A, 16B, and the sheet The material M1 is sent out without being sandwiched between the upper and lower rollers 16A and 16B.
[0028]
When cutting (cutting or trimming) the roll material M2 instead of the sheet material M1, the upper roller 16B is lifted by the air cylinder 31, the table 50 is removed from between the rollers 16A and 16B, and between the rollers 16A and 16B. The delivery end of the roll material M2 is placed, the upper roller 16B is lowered by the air cylinder 31, and is sandwiched between the rollers 16A and 16B to perform the work.
[0029]
Further, a sensor (not shown) is provided between the roll feeder 16 and the movable platen 14 to detect the front ends of the materials to be cut M1 and M2 in the delivery direction and to output detection signals to the drive control device 17. When the sheet material M1 is placed on the table 50 and cut, when the table 50 is arranged between the upper and lower rollers 16A and 16B and the drive control device 17 is turned on, the driving is performed until the sensor detects the front end of the sheet material M1. The control device 17 drives the roll feeder 16 to send the table 50 to the movable platen 14 side, the sensor detects the front end of the sheet material M1, and when the detection signal is sent to the drive control device 17, the drive control device 17 The cutting operation is started on the assumption that cueing to the set position of the sheet material M1 has been completed. That is, when the drive control device 17 sends a positive drive signal to the servo motor 21 based on the work program, the servo motor 21 drives the rollers 16A and 16B to rotate in the forward rotation direction, and feeds the table 50 to the gears 40A and 40B. In synchronism with the rotation, it is sent out toward the movable platen 14 side. Then, the drive control device 17 stops detecting a sheet material M1 that has been cut by a sensor (not shown) or sends a negative drive signal to the servo motor 21 according to a preset work program. Thus, the rollers 16A and 16B are reversely rotated, and the table 50 is fed back from the movable platen 14 toward the original position in synchronization with the reverse rotation of the feed gears 40A and 40B.
[0030]
When the roll material M2 is sandwiched between the rollers 16A and 16B and cut out, the front end of the roll material M2 in the feed direction is sandwiched between the upper and lower rollers 16A and 16B from which the table 50 is removed. At this time, the roll material M2 is pressed by the upper roller 16B with a predetermined pressing force corresponding to the material of the roll material M2. When the drive control device 17 is turned on, the drive control device 17 drives the roll feeder 16 to feed the roll material M2 toward the movable platen 14 until the sensor detects the front end of the roll material M2. When the front end of M2 is detected and a detection signal is sent to the drive control device 17, the drive control device 17 starts cutting operation on the assumption that cueing to the set position of the roll material M2 has been completed. Yes.
[0031]
Next, the operation of the cutting apparatus according to the above embodiment will be described. In order to cut the sheet material M1 by the cutting device 10, first, the table 50 is disposed on the upper surface of the stationary platen 13, and the uncut sheet material M1 is placed on the upper surface of the table 50 via the backing plate 2. And position with adhesive tape. Next, the upper roller 16B is raised to the upper non-clamping position, the front end in the feed direction of the table 50 is inserted into the gap between the rollers 16A and 16B, and the L-shaped metal fittings 53A and 53B are inserted between the two flange portions 42B and 42B. This insertion work is done manually. Next, the upper roller 16B is lowered, and the teeth of the feed gears 40A and 40B are engaged with the rack teeth 52A and 52B of the rack guides 51A and 51B. At this time, the lower surface of the table 50 comes into contact with the upper end of the lower roller 16A. The sheet material M1 is not sandwiched between the upper rollers 16B on the table 50. Then, the drive control device 17 operates the roll feeder 16 until the sheet material M1 is detected by a sensor (not shown), and when the sensor detects the front end portion in the feeding direction of the sheet material M1, the sheet material M1 is at the cutting start position. It is considered that it has been set, and preparations for cutting work are completed.
[0032]
Next, the roll feeder 16 and the movable platen 14 are synchronized based on the input work program, the table 50 is slid on the upper surface of the fixed platen 13, and the sheet material M1 fed together with the table 50 is cut by the blade die 15. I do. At this time, the table 50 is sent out in a state where the L-shaped metal parts 53A and 53B are placed between the two flange portions 42B and 42B, so that the displacement in the width direction is regulated and the table 50 is sent out linearly. For this reason, the table 50 does not meander or skew. Therefore, the material to be cut M1 placed on the table 50 is also fed out in a straight line and does not meander or skew.
[0033]
After the sheet material M1 and the table 50 are fed from the upstream side to the downstream side of the movable platen 14 and are cut, a sensor (not shown) does not detect the cut sheet material M1 or is set in advance. According to the work program, the drive control device 17 drives the servo motor 21 in the reverse direction, feeds the cut sheet material M1 from the movable platen 14 side toward the roll feeder 16 side, and feeds the cut sheet material M1 to the roll feeder. 16 Return to the original upstream position. When a large number of sheet materials M1 are cut, the cut sheet material M1 is removed, the next uncut sheet material M1 is positioned on the contact plate 2, and the above steps are repeated. For this reason, since an operator can work at the same place without moving, the work is made efficient. In addition, after the cutting is performed, the cut sheet material M1 may be removed from the table 50 on the downstream side of the movable platen 14.
[0034]
Next, when cutting (cutting or trimming) the roll material M2 instead of the sheet material M1, the upper roller 16B is first lifted by the air cylinders 31 and 31, and the table 50 is removed from between the rollers 16A and 16B. Next, the distance between the material guides 20A and 20B is adjusted according to the width of the roll material M2, the feed end of the roll material M2 is placed between the rollers 16A and 16B, and the upper roller 16B is lowered by the air cylinder 31. It is sandwiched between the rollers 16A and 16B to perform the work. As described above, in the cutting apparatus according to the above-described embodiment, it can be used as a cutting apparatus capable of cutting regardless of whether the material to be cut is a roll material or a sheet material. Can be achieved. Moreover, in the cutting apparatus according to the above-described embodiment, the work can be performed at the same place without the worker moving, so the work is made efficient.
[0035]
In the above embodiment, the table 50 is made of synthetic resin, but is not limited to this, and may be made of metal (for example, stainless steel, brass, etc.). In the above embodiment, the rack guides 51A and 51B are configured to engage the feed gears 40A and 40B and the collars 41A and 41B, but the present invention is not limited to this, and instead of the collars 41A and 41B. The feed gears 40A and 40B may be provided on the drive shaft 22 side, and rack teeth that mesh with the feed gears 40A and 40B may be formed on the lower surface of the rack guide. In this case, the upper roller 16B may be raised and held at an upper position so as not to interfere with the work. Then, the table moves on the fixed plate 13 accordingly when the drive shaft 22 is driven forward and backward. Further, the sheet material M1 is sent out on the table 50 without being sandwiched between the upper rollers 16B. However, the sheet material M1 is not limited to this. You may make it send out by pinching.
