Description

  The present invention relates to a cut object adhesion prevention device and a cutting machine equipped with a cut object adhesion prevention device, and more particularly to contact between a cutting blade and a cut object when cutting is performed in a state where the cut objects are stacked. The present invention relates to a cut object adhesion preventing device capable of preventing the laminated cut objects from being brought into close contact with each other by frictional heat generated in the above, and a cutting machine equipped with the cut object adhesion preventing apparatus.

Generally, when a large number of parts having the same shape are cut by a cutting machine, cutting is performed in a state where a plurality of objects to be cut are stacked.
In this way, if cutting is performed in a state in which a plurality of objects to be cut are stacked, the number of parts stacked in a single cutting operation can be manufactured, so that the cutting time can be shortened.

However, if cutting is performed in a state in which the objects to be cut are laminated in this way, frictional heat is generated by contact between the cutting blade and the objects to be cut in the cut surface. There was a problem of close contact.
That is, as shown in FIG. 8, the cut surface W is brought into close contact with the frictional heat.
In particular, when the material to be cut is a synthetic material using a resin raw material, the resin raw material having a cut surface is dissolved by the frictional heat and has an adhesive property, and there is a tendency that the adhesion of the cut surface becomes strong.

In addition, the curved portion has a higher adhesion than the straight portion because the cutting speed is reduced.
As described above, when close contact occurs in the cut surface, there is a problem that work efficiency is deteriorated because work for separating the parts one by one is required after the cutting is finished.
For this reason, a method has been proposed in which frictional heat between the cut surface and the cutting blade is eased to prevent the object to be cut from sticking (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-042992 (second page, FIG. 1 and FIG. 2)

The fabric cutting hollow perforated blade described in Patent Document 1 has a hollow portion, and a large number of holes communicating with the hollow portion are formed on its side surface.
Air that has been cooled by an air cooler is fed into the hollow portion, and the frictional heat between the cut surface and the blade is reduced by cutting the blade while cooling the blade with this cooling air.

However, according to the fabric cut hollow perforated blade of Patent Document 1, it is possible to reduce frictional heat between the cut surface and the blade, but it is necessary to use a special blade having a hollow portion and a large number of holes communicating with the hollow portion. Therefore, it was necessary to manufacture a blade having this special shape.
Further, the hollow perforated blade of Patent Document 1 is hollow inside, and a large number of holes serving as air passages are drilled on the side surface, so that the strength is weaker than a conventional cutting blade and the life is shortened. There was a problem. In addition, in this structure, in order to ensure the same strength as that of the conventional cutting blade, measures such as changing the material are necessary, which increases the manufacturing cost.
In addition, since the structure has a hollow portion and a large number of holes, there is a problem that it takes time and effort for maintenance.

This invention is made | formed in view of the said situation, Comprising: The object arises by the contact of the cut surface of the laminated | stacked to-be-cut material, and a cutting blade, when laminating | cutting a to-be-cut object, and cutting. To provide a cutting object adhesion prevention device capable of preventing the cut surfaces of the laminated cut objects from coming into close contact with each other by reducing frictional heat, and a cutting machine equipped with the cut object adhesion prevention apparatus. It is in.
Another object of the present invention is to provide a cut object adhesion preventing apparatus and a cut object adhesion preventing apparatus that do not require special parts and can be easily attached to an existing cutting machine and are easy to maintain. It is in providing a cutting machine equipped with.

  According to the apparatus for preventing the object to be cut as claimed in claim 1, the object is provided in a cutting machine that cuts the object to be cut and stacked on the support base into a shape defined by a cutting blade. An apparatus for preventing adhesion of a cut object, wherein the storage means stores an adhesion preventing material for preventing adhesion of a cut surface of the object to be cut, and is disposed in a movable path of the cutting blade so as to be in contact with the cutting blade. This is solved by including an adhesion prevention material contact portion and a supply means for supplying the adhesion prevention material from the storage means to the adhesion prevention material contact portion.

As described above, in the adhesion preventing apparatus according to the present invention, the adhesion preventing material contact portion for bringing the adhesion preventing material for preventing adhesion of the laminated cut surfaces of the cut objects into contact with the cutting blade is a movable path of the cutting blade. By being provided inside, the adhesion preventing material can be applied to the surface of the cutting blade.
This adhesion preventing material can reduce the frictional heat generated by the contact between the cutting blade and the laminated cut object by reducing the friction coefficient between the cutting blade and the laminated cut object.
Therefore, every time the cutting blade moves along the movable path, an adhesion prevention material is applied to the surface of the cutting blade, and the cutting blades to which the adhesion prevention material is applied are used to perform cutting, thereby stacking the objects to be cut. It is possible to prevent close contact with the cut surface.
For this reason, the process which isolate | separates the to-be-cut material which adhered after cutting can be skipped, and work efficiency can be improved.

At this time, the cutting machine includes a pressing member for pressing the stacked objects to be cut at the time of cutting, and the pressing member is disposed at a position including the movable path of the cutting blade. The member is formed with a cutting blade entrance hole through which the cutting blade is inserted when the cutting blade moves along the movable path, and the contact prevention member contact portion is formed by the cutting blade access hole of the pressing member. It is preferable to be formed in the vicinity.
A pressing member that presses and fixes an object to be cut at the time of cutting is provided in a conventional cutting machine, and a movable path is formed when the cutting blade moves up and down.
Therefore, if it is the structure which provides a contact part in the cutting blade movable path | route of this press member, a contact part can be provided without adding a special modification to the conventional cutting machine, and manufacturing cost can be reduced.
Further, by forming a contact portion in the movable path of the cutting blade, the adhesion preventing material can be automatically attached to the surface of the cutting blade when the cutting blade moves up and down.

Further, the pressing member includes an upper tray that receives a pressing force in the direction of the object to be cut, and a lower tray that is disposed below the upper tray and receives the pressing force transmitted from the upper tray, and is stacked. A lower tray that presses an object, wherein the cutting blade access hole is a first cutting blade access hole formed in the upper tray and a second cutting blade formed in the lower tray The contact member contact portion is a gap formed by the upper tray and the lower tray, and the first cutting blade access hole and the second cutting blade access If it is formed between the holes, it is preferable because the contact portion can be easily formed.
Further, since the contact portion is formed in a gap formed between the upper tray and the lower tray, the space between the upper tray and the lower tray is open, and maintenance can be easily performed.

Furthermore, the supply means includes at least a transport member that is a movement path of the adhesion prevention material and an adjustment means that adjusts the timing of supplying the adhesion prevention material to the contact portion.
At this time, the adjusting means is a solenoid valve, and control means for controlling the opening / closing timing of the solenoid valve is provided.
Since it is comprised in this way, the supply amount of the adhesion prevention material to a contact part can be adjusted.
Therefore, it is possible to prevent leakage of the adhesion preventing material from the contact portion and depletion of the adhesion preventing material, which is preferable.

Further, when the adhesion preventing material is a material containing silicon, the adhesion preventing material can reduce the friction coefficient of an object to be cut laminated with a cutting blade, and can suppress generation of frictional heat.
Therefore, it is preferable because it is possible to effectively prevent the stacked cut surfaces from being cut.

Furthermore, it is preferable that the adhesion preventing material is a gas.
At this time, it is preferable that the apparatus for preventing adhesion of the object to be cut is provided with a gas cooling means, and the adhesion preventing material is used after being cooled by the gas cooling means.
Thus, when a cooling gas is used as the adhesion preventing material, the cutting blade can be cooled by the cooling gas.
Therefore, it is possible to reduce frictional heat due to contact between the cutting blade and the laminated cut object, and thus it is possible to effectively prevent the adhesion of the laminated cut object cut sections.

  In addition, when the cutting machine that cuts the object to be cut into a desired shape with the cutting blade is equipped with these objects to be cut, it is possible to prevent adhesion of the cut objects to be cut. This is preferable because the cutting operation can be performed efficiently.

According to the adhesion preventing apparatus according to the present invention, the contact portion for contacting the cutting blade with the adhesion preventing material for preventing the adhesion of the laminated cut surfaces is provided, thereby preventing adhesion on the surface of the cutting blade. Material can be applied.
This adhesion preventing material can reduce the friction coefficient between the cutting blade and the laminated object to be cut, and reduce the frictional heat generated when the cutting blade comes into contact with the laminated object to be cut.
Therefore, by cutting using a cutting blade coated with an adhesion preventing material on the surface, it is possible to prevent adhesion of the cut surfaces of the laminated cut objects, and a step of separating the objects to be cut that are in close contact after cutting Can be omitted.
For this reason, working efficiency can be improved.

Moreover, since it is the structure which provides a contact part in the press member with which the conventional cutting machine is provided, a contact part can be provided, without adding a special modification to the conventional cutting machine.
Furthermore, in the conventional cutting machine, the cutting blade moves up and down through the inside of the pressing member, but when the cutting blade moves up and down by forming a contact portion in the movable path of this cutting blade, The adhesion preventing material can be automatically attached to the surface of the cutting blade.
As described above, the contact prevention device according to the present invention can form the contact portion without adding any special modification to the conventional cutting machine, and it is not necessary to use a special member such as a modified cutting blade. It can be easily adopted in a conventional cutting machine.
Therefore, the cost for installing the to-be-cut object adhesion prevention device can be reduced.
More specifically, the contact portion is formed in the gap between the upper tray and the lower tray.
Therefore, since the upper tray and the lower tray are open, maintenance can be easily performed.

The supply means is provided with an electromagnetic valve as an adjustment means for adjusting the timing of supplying the adhesion preventing material to the contact portion, and a control means for controlling the opening / closing timing of the electromagnetic valve.
For this reason, in the adhesion preventing apparatus according to the present invention, the supply amount of the adhesion preventing material to the contact portion can be adjusted, and leakage of the adhesion preventing material from the contact portion and depletion of the adhesion preventing material can be prevented. It becomes possible.

Furthermore, silicon or cooling gas is used as an adhesion preventing material, but these materials can be easily obtained.
In particular, since parts that use gas as a drive source, such as an air cylinder, are normally used in the cutting machine, the gas can be easily separated from the gas supply source of these parts.
Therefore, in the adhesion preventing device according to the present invention, the adhesion preventing material can be easily supplied without requiring a special material or a special member.

In this way, with the upper tray 74b and the lower tray 74c attached via the collar 74d, the gap formed between the lower surface side of the upper tray 74b and the opening side surface of the lower tray 74c is defined as follows. This is described as “reservation space 74e”.
This storage space 74e corresponds to a contact portion.
The free end of the injection tube 73 is disposed in the storage space 74e.
Thus, the silicon 71a is injected from the injection pipe 73 into the storage space 74e and stored in the storage space 74e.
Note that a silicon impregnating material such as felt is disposed in the storage space 74e.
Therefore, the silicon 71a is stored in the storage space 74e in a state of being impregnated with the silicon-impregnated material.
The storage space 74e moves up and down integrally when the silicon contact portion 74 moves up and down (moves in the XY direction in FIG. 5).

This vertical movement mechanism is the same as the workpiece pressing mechanism of a known cutting machine.
For example, in this embodiment, the silicon contact portion 74 is suspended from the cutting head 7 body by two helical springs 51 attached to the upper surface of the upper lid 74a.
A pressing cylinder 41 for pressing down the silicon contact portion 74 is provided, and a pressing member 42 is disposed at the tip of the rod of the pressing cylinder 41.
On the free end side of the pressing member 42, a substantially cylindrical pressing application portion 42a is provided, and this pressing application portion 42a is in contact with the upper surface of the upper lid 74a.

  Therefore, when compressed air is introduced into the pressing cylinder 41 and the rod of the pressing cylinder 41 extends in the lower direction (Y direction in FIG. 5), the pressing member 42 is pushed down in the lower direction (Y direction in FIG. 5). The press application unit 42a provided on the free end side presses the upper lid 74a in the lower direction (Y direction in FIG. 5).

With this pressing force, the silicon contact portion 74 moves in the lower direction (Y direction in FIG. 5) against the restoring force of the helical spring 51, and faces the lowermost surface (the workpiece 10) of the lower tray 74c. Surface) is pressed against the workpiece 10. In this way, the object to be cut 10 is pressed during cutting.
Further, when the introduction of the compressed air to the pressing cylinder 41 is switched and the rod is returned to the original position, the pressing member 42 moves in the upper direction (X direction in FIG. 5), so the pressing force applied to the upper lid 74a is Canceled.
When the pressing force is released in this way, the silicon contact portion 74 moves upward due to the restoring force of the helical spring 51 and returns to the original position.

Note that the two guide bars 31 stand substantially vertically on the upper surface of the upper lid 74a in the upper direction (X direction in FIG. 5).
The guide bar 31 is disposed so as to be able to enter and exit in a guide path (not shown) having a passage in the vertical direction, and the silicon fixed to the guide bar 31 as the guide bar 31 enters and exits along the guide path. The contact portion 74 can move in the vertical direction against the swing of the helical spring 51.

Cutting the workpiece 10 is performed by operating the cutting blade S in a state where the lower tray 74c is pressed against the workpiece 10 and the workpiece 10 is fixed.
The cutting blade S can move up and down from the position of P in FIG. 5 to the position of Q through the hole formed in the upper lid 74a, the through hole 74g, and the through hole 74f. Pass 74e.
Thus, when the cutting blade S passes through the storage space 74e, it contacts the silicon impregnated material impregnated with the silicon 71a disposed in the storage space 74e.
At this time, the silicon 71 a impregnated in the silicon impregnated material adheres to the cutting blade S.
The silicon 71a adhering to the cutting blade S can reduce the friction coefficient between the cutting blade S and the object 10 to be cut.
Thus, by performing cutting using the cutting blade S with the silicon 71a attached to the surface, it is possible to reduce the generation of frictional heat caused by the contact between the cutting blade S and the workpiece 10.
For this reason, it is possible to effectively prevent the cut surface of the object to be cut, which has been generated due to frictional heat between the cutting blade S and the object 10 to be cut.

(Other embodiments)
In the embodiment described above, silicon is used as the material to prevent the object to be cut, but cooling air can also be used.
Hereinafter, the case where cooling air is used as an adhesion preventing material will be described.
Since the outline of the apparatus is the same as that of the above-described embodiment, only differences are described, and the same reference numerals are used when the same members as those of the above-described embodiment are used.

As shown in FIG. 7, the cooling air supply device 100 according to the present embodiment includes a moisture removal filter 101, an air cooler 102, a connection tube 103, and a transport tube 104.
Air is supplied from an air compressor (not shown).
In the cutting machine 1, various air cylinders are used as a drive source, and air is supplied to these air cylinders from an air compressor.
In the present embodiment, air is separated from the air compressor.

The moisture removal filter 101 according to the present embodiment is a known filter, removes moisture contained in air supplied by an air compressor, and sends out dried air.
Note that the moisture removal filter 101 is not necessarily used.
The air cooler 102 according to the present embodiment is a known air cooling device that lowers the temperature of air and sends out cooling air.

The connection tube 103 according to the present embodiment is a known resin tube, one end is connected to the secondary side of the moisture removal filter 101, and the other end is connected to the primary side of the air cooler 102.
The transport tube 104 is a known resin tube, one end of which is connected to the secondary side of the air cooler 102, and the other end is connected to the second adapter 71i.

Air supplied from an air compressor (not shown) is sent to the moisture removal filter 101.
Next, the dry air from which moisture has been removed by the moisture removal filter 101 is sent to the air cooler 102 through the connection tube 103.
The cooling air cooled by the air cooler 102 is supplied to the second adapter 71i, the adjusting device 72, and the injection pipe 73 through the transport tube 104, and finally sent to the storage space 74e.

Therefore, when the cutting blade S passes through the storage space 74e, the cooling air sent into the storage space 74e is exposed to the cutting blade S.
In this case, it is not necessary to arrange a silicon impregnating material such as felt in the storage space 74e.
Since the cutting blade S is cooled by the cooling air exposed to the cutting blade S, the frictional heat generated by the contact between the cutting blade S and the workpiece 10 can be reduced.
For this reason, it is possible to effectively prevent the cut surface of the object to be cut, which has been generated due to frictional heat between the cutting blade S and the object 10 to be cut.
