Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a non-metal saw blade made of paper, plastic, etc., and a non-metal saw blade manufactured to a carton before assembly. The present invention relates to a non-metal saw blade manufacturing attachment device to be attached.

[0002]

2. Description of the Related Art Conventionally, when a metal cutting blade having a saw blade is attached to a rectangular parallelepiped carton containing a wound aluminum foil or a resin film, the aluminum foil or the resin film is used as an aluminum foil. A structure in which a foil or a resin film is pulled out from the carton and separated by a cutting blade is widely used. Conventional devices for manufacturing such a carton with a cutting blade are disclosed in, for example, Japanese Patent Application Laid-Open Nos. 1-294029 and 2-29321. The devices shown in these publications punch a cutting blade from a metal plate with a mold die set consisting of a male die and a female die,
It was fed above the die set and was configured to be crimped to a stopped carton.

[0003]

However, in such a conventional carton with a cutting blade, since a metal blade such as aluminum is used, the metal blade cannot be incinerated when the carton is incinerated, which causes an environmental problem. Was there. Therefore, it is desired to replace the conventional cutting blade with a flammable cutting blade made of paper or plastic.

In order to manufacture a cutting blade made of paper, plastic or the like (hereinafter referred to as a non-metal saw blade) and attach it to a carton, the cutting blade attaching device disclosed in the above publication is used to produce a metal blade. It is conceivable that a non-metal raw material such as paper or plastic may be supplied instead of the metal plate of No. 2.
However, when a non-metal raw material such as paper or plastic is punched out by a die set, it has been found that there is a problem that the formed non-metal saw blade has a rounded tip end, resulting in poor sharpness. . That is, as shown in FIGS. 11A and 11B, the male die 101 and the female die 1
When the saw blade 104 is manufactured by punching out the raw fabric 103 with a die set including 02, the shearing action between the male mold and the female mold is used for punching the raw fabric. In order to prevent the blades of the female mold from colliding with each other, as shown in an enlarged view in FIG. 12, a minute gap 105 must be left between the blades of the male mold 101 and the female mold 102.
A relatively large gap 106 is formed in the portion corresponding to the tip of the male or female saw blade. For this reason, the saw blade 104 manufactured by this die set has a rounded tip 104a, as shown in FIG. Such roundness of the tip of the saw blade occurs even with a metal blade, but since the hardness of the metal blade is large, it does not pose a problem so much, but with paper or plastic etc., the hardness is low and the sharpness is extremely poor, which is a big problem. Became.

In the conventional device shown in the above publication, the cutting blade is attached to the carton by caulking, but the non-metal saw blade cannot be attached by caulking. Therefore, the conventional device shown in the above publication is non-metallic. Cannot be used to attach saw blade to carton. Furthermore, since the above-mentioned conventional device is configured to punch the cutting blade with the die set that moves up and down and attach it to the carton stopped above it, the carton is intermittently supplied to a predetermined position above the die set. However, there was also a problem that it was discharged and production efficiency was poor.

The present invention has been made in view of the above-mentioned problems, and it is possible to manufacture a non-metal saw blade having a sharp saw-tooth edge from a non-metal raw material such as paper and plastic. An object is to provide a method for manufacturing a non-metal saw blade.

Further, according to the present invention, a non-metal saw blade having a sharp saw edge is manufactured from a non-metal raw material such as paper or plastic, and the non-metal saw blade is attached to a carton with high production efficiency. An object of the present invention is to provide a non-metallic saw blade manufacturing attachment device that enables the above.

[0008]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have made a non-metal original fabric supported on a flat receiving surface instead of punching by a die set.
A non-metallic saw blade with a sharp edge without roundness at the blade tip by pushing a cutter blade with a blade edge that matches the blade edge shape in the plane of the saw blade into the non-metal original fabric to cut It was found that the non-metal saw blade can be manufactured with high production efficiency by providing the cutter blade and the receiving surface on a pair of rolls, and completed the method of the present invention.

Further, after a non-metal saw blade is manufactured from a non-metal raw fabric by a roll having a cutter blade and a roll having a receiving surface, the non-metal saw blade is sucked and held by a roll having a receiving surface. The inventors have completed the device of the present invention by paying attention to the fact that a non-metal saw blade can be easily attached to a carton that is continuously running by supplying the carton.

That is, the present invention according to claim 1 is a cutter blade which is provided so as to project substantially outward in the radial direction, and the shape of the blade edge when the blade is viewed from the direction facing the blade edge. A cutter roll having a cutter blade having a cutting edge shape in the plane of a saw blade to be manufactured, and a non-metal original fabric is supplied between a receiving roll having a flat receiving surface for receiving the cutter blade, The cutter roll and the receiving roll were synchronously rotated so that the cutter blade tip and the receiving surface moved at the same speed, and supported by the receiving surface while conveying the non-metal original fabric at the same speed as the cutter blade tip. A gist of a method of manufacturing a non-metal saw blade is characterized in that a cutter blade is cut into a non-metal original fabric and cut into a saw blade shape. Here, the cutter blade attached to the cutter roll may be attached to the cutter roll so as to extend substantially in the axial direction, or may be attached in the circumferential direction.

Further, the present invention according to claim 2 uses an apparatus for carrying out the method for manufacturing a non-metallic saw blade according to the method of the present invention, and conveys a carton to which the non-metal saw blade is attached. The device and the gluing device that glues the carton being transported by the transporting device to a predetermined position, and the continuous non-metal raw material are separated so as to form a non-metal saw blade, and the saw is pasted to the gluing position of the carton. A saw blade manufacturing and laminating apparatus, wherein the saw blade manufacturing and laminating apparatus is a cutter blade provided so as to project substantially outward in the radial direction and extend in the substantially axial direction, and the cutter blade is used as a blade tip. A cutter roll having a cutter blade whose cutting edge shape when viewed from the opposite direction is equal to the cutting edge shape in the plane of the saw blade to be manufactured, and a flat receiving surface for receiving the cutter blade. And a suction roll having a suction hole for sucking and holding the separated non-metal saw blade and provided so as to rotate in parallel with and synchronously with the cutter roll. A gist of a non-metallic saw blade manufacturing attachment device is characterized in that the saw blade is arranged at a position to be attached to a carton conveyed by the conveying device.

[0012]

According to the above-described method of the present invention, the cutter blade cuts into the non-metal raw fabric which is supported by the receiving surface of the receiving roll and is running, and the raw fabric is cut into a shape corresponding to the shape of the cutting edge of the cutter blade. At this time, only the cutter blade cuts into the original fabric,
Since the original fabric is pushed through, the original fabric can be accurately cut into the shape of a cutter blade, and by forming the bent portion of the cutter blade tip sharply, a rounded saw blade can be formed. it can. Further, since the raw material is cut by the rotation of the roll to manufacture the saw blade, the production speed can be increased. Here, when the cutter blade is provided almost in the axial direction with respect to the cutter roll, the non-metal saw blade can be manufactured by separating the raw material in the width direction, and the cutter blade can be provided with respect to the cutter roll. When provided in the circumferential direction, the non-metal saw blade can be manufactured by cutting the raw material in the longitudinal direction.

When the cutter blade is cut into an original fabric supported by the receiving surface and the original fabric is cut, the tip of the cutter blade is surely brought into contact with the receiving surface to surely separate the original fabric. There is no need to use a cutter blade, and the cutter blade may be in non-contact with the receiving surface so that a thin film that cannot be cut remains in the original film, and the thin film may be torn and cut by an appropriate means. With this configuration, the cutter blade does not contact the receiving surface, wear of the cutter blade can be suppressed, and the life can be extended.

Next, in the apparatus of the present invention having the above-mentioned structure, the carrying device causes the carton to travel along a predetermined route, and during that time,
The sizing device applies glue to the running carton at a predetermined position, and the saw blade manufacturing and pasting device cuts the non-metal raw fabric to form a non-metal saw blade, and the non-metal saw blade is applied to the carton glue. The non-metallic saw blade can be attached to the carton by pasting it on the application part. Here, the saw blade manufacturing / pasting apparatus is of a rotary cutter type including a cutter roll having a cutter blade, and a suction roll having a receiving surface for receiving the cutter blade and a suction hole for holding the saw blade, that is, a receiving roll. Therefore, it is possible to cut the non-metal original fabric into a sharp non-metal saw blade without rounding the tip of the saw blade. Further, since the suction roll rotates by sucking and holding the non-metal saw blade separated from the non-metal raw fabric, by synchronizing the peripheral speed of the suction roll and the traveling speed of the carton by the transport device, the carton in motion. The non-metal saw blade can be pressed to a predetermined position of the non-metal saw blade, and the non-metal saw blade can be pressed and stuck to the glued portion of the carton which is continuously running. Therefore, a carton with a non-metal saw blade can be manufactured with high production efficiency.

A saw blade manufacturing / pasting device 33 is provided above the carton traveling position of the transport device 10 and downstream of the gluing device 20. This saw blade manufacturing and pasting device 33 is
A cutter roll 37 having a cutter blade 36 is provided for cutting a tip (see FIG. 5) of a non-metal raw material 35 such as a paper raw material into a saw-tooth shape to form a non-metal saw blade 7 and attaching it to a carton. It is of a rotary cutter type, which is provided with a receiving roll 40 which is provided so as to rotate in parallel and synchronously. As shown in FIGS. 3 and 4, the cutter blade 36 provided on the cutter roll 37 is provided so as to project outward in the radial direction of the roll and extend in the axial direction of the roll, and the cutter thereof. The shape of the cutting edge when the blade 36 is seen facing the cutting edge is zigzag so as to be equal to the shape of the cutting edge in the plane of the saw blade to be manufactured. FIG. 6 shows the shape of the cutting edge in an enlarged manner, and the bent portions 36b and 36c of the cutting edge 36a are sharpened without being rounded. With this configuration,
The non-metallic saw blade 7 (see FIG. 5) formed by the cutter blade 36 can form a sharply sharp saw blade without causing roundness at the blade tips 7a and 7b.

3 and 4, the receiving roll 40 has a receiving member 38 having a flat receiving surface 38a for receiving the cutter blade 36, and a suction hole 39 for sucking and holding the non-metal saw blade 7 to be separated. There is. Here, the fact that the receiving surface 38a of the receiving roll 40 is flat means that it does not have a groove into which the cutter blade 36 is inserted, and is not limited to a flat surface in the strict sense. It may be a cylindrical surface. The cutter roll 37 and the receiving roll 40 are synchronously rotated so that the tip of the cutter blade 36 and the receiving surface 38a move at the same speed, and convey the non-metal original fabric 35 at the same speed as the tip of the cutter blade 36. However, by cutting the cutter blade 36 into the non-metal raw fabric 35 supported by the receiving surface 38a, the non-metal raw fabric 35 can be cut into the same blade edge shape as the cutter blade, that is, a saw-tooth shape. The saw blade 7 can be formed. The receiving roll 40 also has a function of sucking and holding the non-metal saw blade 7 separated from the non-metal raw fabric 35 by the suction hole 39.

It is set so that a minute clearance is left between the blade edge of and the receiving surface 38a. The size d of this clearance is 0.005 mm to 0.03 m
About m is preferable, and about 0.01 mm is particularly preferable.
When the cutting edge of the cutter blade 36 is kept out of contact with the receiving surface 38a in this manner, the receiving surface 38a, which is usually made of hard metal, does not hit or damage the receiving surface 38a. The life of the cutter blade 36 can be extended. In addition, in this way the cutter blade 3
If a minute clearance is formed between the 6 and the receiving surface 38a, when the cutter blade 36 cuts into the non-metal original fabric 35, the original fabric 35 cannot be reliably separated and one thin skin remains. It becomes a shape. However, the portion of the front end of the original fabric 35 that is cut off to become the non-metal saw blade 7 is sucked by the suction roll 40.
By sucking and transporting with the non-metal saw, the raw fabric 35 is braked at the same time, a tensile force acts between the raw fabric 35 and the non-metal saw blade 7, tearing the thin skin remaining between the two, and the non-metal saw. Since the blade 7 can be well separated from the original 35,
There is no hindrance.

The inspection device 45 includes three cameras for observing a predetermined position on the upper surface of the carton. FIG. 7 shows an observation position by the camera, 46 is an observation region by the first camera, and 46a is a detection line, which is used to detect the arrival of the tip of the carton 2 flowing in the arrow direction. It 47 is the observation area by the second camera, 47a and 47b are the detection lines,
Reference numeral 48 is an observation area by the third camera, and 48a and 48b are detection lines thereof. The observation areas 47 and 48 are arranged so as to observe two places apart in the width direction of the carton 2. The positions and intervals of the detection lines 47a, 47b and the detection lines 48a, 48b are such that the non-metal saw blade 7 attached with the attachment accuracy within the allowable range reaches the predetermined position at the front detection line 47a, 48
