2. Description of the Related Art Conventionally, in manufacturing a duct, a method has been adopted in which each member constituting the duct is cut out from a thin plate material and assembled with a goby or the like. Recently, various automated or semi-automated devices have been developed for cutting out such members by NC control using not only gas but also laser or plasma.

In such an NC-type duct material fusing apparatus, when cutting a large number of members from a plate member placed on a table at once, for example, from the plate removing position set as shown in FIG. When one member A is melted and cut in the order of the sides L1, L2, ...
.. were melted in this order, and the members C, D ,.

[0004]

By the way, each side L1,
L2, ... is not a great length, and each side L1, L
Since the moving speed of the torch must be reduced near the end points of 2, ..., In the conventional device, deceleration is frequently performed. In the illustrated example, the number of times is (number of parts) × (number of sides) =
12 × 4 = 48 times. Therefore, there is a problem that it takes a long time to melt.

Further, since the frame portion Z remains after the completion of the fusing of all the members, it has to be removed from the work table of the fusing device. However, as a result of the plate cutting position being set so as to narrow the interval between the members, the frame portion Z is formed as a continuous thin strip plate, and is deformed in a complicated manner due to expansion due to heat input during fusing, It was difficult to handle.

Therefore, the present invention has been completed for the purpose of providing an assembling component fusing device and an assembling component fusing information creating device which can reduce the fusing time and simplify the post-processing.

[0007]

SUMMARY OF THE INVENTION The assembly fusing device of the present invention, which has been made to achieve the above object, has a plurality of plate cutting positions set on a sheet material, as shown in FIG. In an assembly component fusing device including a fusing means M11 for fusing an assembly part along a side forming a contour of the assembly part, a fusing information providing means for providing the fusing means M11 with independent fusing information regarding a fusing line having the side as a unit. M12
And a contact information unifying unit M13 that regards, as one piece of the fusing information, the fusing information pieces whose ends contact each other at an obtuse angle of a predetermined angle or more.

According to the assembling device fusing device of the first aspect, the fusing information unified by the contact information consolidating means M13 comes into contact with each other at an obtuse angle of a predetermined angle or more, that is, in a state of small bending. It is one that fits together. Therefore, the fusing means M11 can fuse these unified edge groups with one acceleration and deceleration. Therefore, the fusing time can be significantly reduced. The premise that such fusing is possible is that the fusing information providing means M12 provides independent fusing information in units of sides as described above. That is, in fusing, the fusing has become possible beyond the concept of an assembly part, and as a result, it has become possible to unify the sides.

On the other hand, in order to carry out the fusing with such a remarkable action and effect for a general fusing device, as shown in FIG. 2, the plate cutting positions of a plurality of assembly parts are set on the sheet material. An assembly part including a plate cutting position setting means M21 and a fusing information creating means M22 for creating fusing information on the basis of a side forming an outline of the assembly part having the plate cutting position set by the plate cutting position setting means M21. In the fusing information creating apparatus, when setting the plate removing position by the plate removing position setting unit M21, the contacting unit M23 for contacting ends of predetermined sides of adjacent assembly parts and the contacted sides are formed. The melting means includes extraction means M24 for extracting an obtuse edge group whose angle is equal to or larger than a predetermined angle, and contact edge unification means M25 for regarding the edge group extracted by the extraction means M24 as one edge. Creating means M22, it is effective assembly fusing information generating apparatus characterized by creating a separate blown information about blown rays the edges as a unit.

According to this assembly component fusing information creation device,
When the angle formed by the sides that are brought into contact with each other so that the ends of the adjacent assembly parts are in contact with each other is less than or equal to a predetermined angle, these are regarded as one side. As a result, in the fusing information creating means M22, a plurality of items of fusing information that would otherwise be combined into one fusing information. Further, since the fusing information creating means M22 creates the fusing information as independent items, it is possible to determine the fusing order and the like across the assembled parts.

As a result, in the fusing device to which this information is given, fusing is performed as if the contacting side is one long side. Moreover, since the fusing information has only a bend of a predetermined angle or less, the fusing can be performed without deceleration on the way. Therefore, according to this assembly component fusing information creation device, the conventional NC fusing device can also be the fusing device according to claim 1.

Further, in order to achieve the object of high-speed fusing, the present invention also has a plurality of assembly parts having plate cutting positions set on a sheet material, as shown in FIG. In the assembly component fusing device including the fusing means M31 for fusing along the fusing means, a fusing information providing means M32 for providing the fusing means M31 with independent fusing information regarding fusing lines with the sides as units, and the fusing information, The assembly-part melting device according to claim 3, further comprising: overlapping information unifying means M33 that regards the melting information having overlapping parts as one piece of melting information.

According to the assembly fusing device of the third aspect, since the overlapping sides are the targets of one fusing operation, the fusing time is 1 for these sides.
It can be / 2. Traditionally, in such cases 2
It is necessary to perform the fusing operation once every time, and there is a problem that a large heat input effect is exerted on the adjacent parts in the gas fusing. Further, in plasma fusing, since plasma discharge becomes impossible for the second time, such arrangement of the assembled parts in contact with each other was not possible in the first place. That is, even if the adjacent assembly parts are arranged in a state where the sides are overlapped with each other by the fusing device according to the third aspect, there is no problem due to the influence of the cutting of the adjacent parts, and the fusing is impossible. When performing the automated fusing, the frame between the parts can be eliminated, and the post-processing time can be significantly reduced.

On the other hand, in order to carry out the fusing with such remarkable effects on the general fusing device, as shown in FIG. 4, the plate cutting positions of a plurality of assembly parts are set on the sheet material. Assembly parts including plate removal position setting means M41 and fusing information creating means M42 for creating fusing information based on the sides forming the contours of the assembly parts whose plate removal positions are set by the plate removal position setting means M41. In the fusing information creating apparatus, when setting the plate cutting position in the plate cutting position setting unit M41, a superimposing unit M43 for superimposing the sides of adjacent assembly parts, and the superposed sides as one side. The overlapping side unifying means M44 to be considered is provided, and the fusing information creating means M42 creates independent fusing information regarding the fusing line in units of the sides. 4 assembly fusing information generating apparatus according is valid.

According to this assembly component fusing information creation device,
As a result of the sides overlapped between the adjacent assembly parts being regarded as one side, the fusing information creating means M42 collects a plurality of fusing information that would otherwise be plural fusing information. It will be. Also,
Since the fusing information creating means M42 creates the fusing information as independent items, it is possible to determine the fusing order and the like across the assembled parts.

As a result, in the fusing apparatus to which this information is given, the fusing is performed as if the two overlapping sides are one side. Therefore, according to this assembly component fusing information creation device, the conventional NC fusing device can be used to omit fusing on one side between adjacent parts as in the fusing device according to claim 3. it can.

Here, it should be noted that this assembly component fusing information creation device is not merely for superimposing sides. For example, assuming a case where the plasma fusing is performed simply by overlapping the sides, there is a problem that the plasma discharge cannot be performed and the operation becomes impossible as described above. Further, in the case of gas fusing, the ignition cannot be disabled, but there is a risk of deformation of parts due to unnecessary heat input. In other words, in the past, good fusing could not be performed simply by adding a configuration in which the sides are brought into contact with the fusing information creating device, and therefore it was necessary to leave a certain frame.

However, the apparatus for fusing information on fused parts of the present invention can also prevent the trouble newly caused by the overlapping of the sides by including the overlapping side unifying means M42. For the first time, it became possible to leave no frame between the parts. As a result,
The troublesome frame part of the post-processing can be greatly reduced.

Embodiments In order to further clarify the structure and operation of the present invention described above, an embodiment of a duct material fusing apparatus to which the present invention is applied will be described. FIG. 5 and FIG. 6 show a schematic configuration of the duct material fusing device 1 as one embodiment of the present invention.

As shown in the figure, this duct material fusing device 1
Is a work table 3 of about 2m x 4m,
A gate-shaped frame 5 conveyed on the work table 3 in the X-axis direction (longitudinal direction), a processing head 7 moved on the gate-shaped frame 5 in the Y-axis direction (width direction of the plate material), and NC.
And a control unit 10. Processing head 7
A marking unit 21 composed of an oil-based pen and its driving mechanism, and a plasma unit 23 composed of a plasma torch and its driving mechanism are arranged therein.

Further, the duct material fusing device 1 does not realize the present invention by itself, but realizes the present invention in combination with a separate fusing information creating device 30. The fusing information creating device 30 includes a CPU 32, a ROM 34,
It is a desktop computer equipped with a RAM 36. The fusing information creating device 30 executes various arithmetic processes in accordance with inputs from a keyboard 41 and a mouse 43 connected via the I / O port 38, and connects the results via the I / O port 38 as well. The output is output to the display 45 and the floppy disk driver 47. In the floppy disk driver 47, NC information for fusing is written in the floppy disk 50.

On the other hand, the NC control unit 10 is also C
It is a computer including a PU 12, a ROM 14, and a RAM 16. The NC control unit 10 starts processing in response to an input from the operation panel 25 connected via the I / O port 18, and the floppy disk driver 27
XY motor 29 that reads various NC information relating to fusing from and drives the gate-shaped frame 5 and the processing head 7.
The marking unit 21 and the plasma unit 23 are driven and controlled, and the overall control of the operation of melting and cutting the duct member from the iron plate 60 is performed. Note that the NC information at this time is created by the fusing information creation device 30 and is stored in the floppy disk 50.
The information written in is used.

Next, the content of the fusing information creating process in the fusing information creating device 30 will be described with reference to FIG. In this process, first, the duct shape input process is executed based on the input from the keyboard 41 (S10). In this process, basic duct dimensions, for example, in the case of a square duct, dimensions such as the width and height on the front side, the width and height on the front side, and the length of the duct are input, and as shown in the upper part of FIG. , Based on it trapezoidal or rectangular duct members A-1, A-2, A
-3 and A-4 are made into figures.

Subsequently, a position moving process is executed based on the operation of the mouse 43 and the keyboard 41 (S20).
This process consists of rotational movement and parallel movement. In rotational movement, specify the member to be rotated and set the rotation angle to 9
By designating any one of 0, 180, 270 and 360 degrees, the rotational movement of the figure is executed around the centroid of the member. In parallel movement, the member to be moved and the end point of the side that is the reference for moving are specified, and by specifying the point to which this end point should be moved, the specified points are overlapped in parallel. Perform a move.

Explaining based on the example of FIG. 8, first, using the mouse 43 and the keyboard 41, “rotation” is selected as the movement method, and the duct member A-3 is designated as the member to be moved, and the rotation is performed. Enter "180 degrees" as the angle. Then, the duct member A-3 is rotated 180 degrees. Next, select "Translation" as the movement method,
The duct member A-3 is designated again as a member to be moved, and each end point symbol DL31T, DL of the side DL31 of the duct member A-3 and the side DL11 of the duct member A-1.
Specify 11T in order. Then, the duct member A-3 after being rotated by 180 degrees is translated so that the designated end point symbols DL31T and DL11T overlap each other. As a result, the side DL31 of the duct member A-3 is changed to the side D of the duct member A-1.
It is superimposed on L11.

Next, "parallel movement" is designated as the movement method, and the duct member A-2 is designated as the member to be moved. Then, the end point symbol DL21T of the side DL21 is designated, and further, the end point symbol DL33T of the side DL33 of the duct member A-3 is designated. Then, the duct member A is placed so that the designated end point symbols DL21T and DL33T overlap each other.
-2 is translated. As a result, the sides DL21 and DL24 of the duct member A-2 and the side DL of the duct member A-3.
33 and 33 are arranged so that their end points are in contact with each other. Especially, the side D
L24 and side DL33 are arranged on a straight line. As a result, the side DL21 of the duct member A-2 is the side DL14 of the duct member A-1 and the side DL32 of the duct member A-3.
It can also be seen as overlapping.

Further, "rotation" is selected as the movement method, the duct member A-4 is designated as the member to be moved, and "90 degrees" is input as the rotation angle. Then, the duct member A-4 is rotated 90 degrees. Subsequently, “parallel movement” is selected as the movement method, the duct member A-4 is designated again as the member to be moved, and the side DL41 of the duct member A-4 and the side DL2 of the duct member A-3 are selected.
4 end point symbols DL41T and DL24T are designated in order. Then, the designated end point symbols DL41T, D
Duct member A-rotated 90 degrees so that L24T overlaps
4 is translated. As a result, the side DL41 of the duct member A-4 is overlapped with the side DL-24 of the duct member A-2.

As a result of these operations, as shown in the middle part of FIG. 8, the four duct members A-1 to A-4 are overlapped with each other at certain sides and moved to a position where the end points of the certain sides are in contact with each other. It is placed compactly. When this position movement processing is completed, the presence or absence of overlapping sides is subsequently determined for the moved duct members A-1 to A-4 (S30). Then, if there are overlapping sides, the overlapping side unifying process is performed to regard them as one side (S40). As a result of this processing, for example, the side DL11 of the duct member A-1 and the side DL31 of the duct member A-3 are regarded as one side. On the other hand, if there is no overlapping side, the process of S40 is skipped.

Next, it is determined whether or not there is a side where the end points contact (S50). If there is a side where the end points contact, it is determined whether or not the angle between the end sides of the contacting sides is an obtuse angle of a predetermined value or more (S60). An angle that does not require deceleration when the machining head 7 is moved is set as a determination condition for an obtuse angle greater than or equal to this predetermined value. If it is determined that the angle is an obtuse angle that is equal to or greater than a predetermined value, contact side unification processing that considers those sides as one side is executed (S70). It should be noted that if “NO” is determined in the process of S50 or S60, the process of S70 is passed.

In FIG. 8, the end point contact is the point P1,
It occurs in P2, P3, and P4. However, the angles θ1, θ3, and θ5 are acute angles or right angles, and the angle θ7 is an obtuse angle, but it is not equal to or more than a predetermined value. Therefore, it is determined as “NO” in the processing of S60. On the other hand, the angles θ2, θ4, θ
6 and θ8 are 180 degrees, and both are obtuse angles that are equal to or greater than a predetermined value, so that “YES” is determined in the processing of S60.

Then, based on the edges unified in the processing of S40 and S70 and the edges in the state as they are, the edges are set to 1
Fusing information as a unit is created (S80), and the result is N
It is written in the floppy disk 50 as C data (S9
0). The fusing information NC1, NC2, ... As NC data written on the floppy disk 50 is schematically shown in the lower part of FIG. This information also indicates the fusing sequence. The order is NC1, NC2, NC3, .... The arrow indicates the fusing direction. As a criterion for determining the fusing order and the fusing direction, a method of giving priority to a side having a long length and giving priority to a side near the side was used.
The number of sides of the original duct members A-1 to A-4 is 4 × 4 =
16 lines are set as if they were 8 sides as a result of this processing. Also, the fusing information NC1,
It should also be noted that it is set as a side longer than the original side as seen in NC2 and NC4. That is, according to this NC data, the number of decelerations during fusing is significantly reduced, and the proportion of the high-speed moving section is increased by the longer time, and the fusing time can be significantly reduced.

Then, the floppy disk 50 in which the NC data as the fusing information is written is attached to the floppy disk driver 27 of the NC control unit 10, and the fusing program is started. This fusing program is executed according to the procedure shown in FIG. That is, the floppy desk 5
NC data as fusing information is read from 0 (S11
0), the marking process is executed first (S12).
0). This marking process is performed by the applicant of the present application and is published in Japanese Patent Application Laid-Open No. 1-53767.
13184), and as shown in FIG. 10, the phase number information 20 meaning that the duct members A-1 to A-4 are a set of duct members.
1, source information 20 which means the width and height of the source side and the destination side
3, top / bottom left / right information 205 indicating which of the top / bottom left / right positions when the duct member A-1 is assembled, a single goby fold as a connection relationship with a duct connected in the longitudinal direction A set code 200 including the connection information 207 that indicates whether it is a double or double is added.

After this set code is written in the planned plate cutting positions of the duct members A-1 to A-4, the fusing is subsequently performed based on the fusing information NC1, NC2, NC3, ... (S130). In this fusing, a long fusing line can be blown at high speed, and only 4 times of acceleration / deceleration operation can be performed.
Fusing of the duct members A-1 to A-4 can be performed. Further, in this example, in particular, since there is no frame between the duct members A-1 to A-4, the post-treatment after fusing is extremely simple.

On the other hand, in the case of the conventional fusing information creating apparatus, in order to avoid the state where the plasma discharge is impossible, FIG.
As shown in the upper part of FIG. 3, the plate cutting position had to be set so that the frame Z remained in between. Further, since the fusing information has a configuration in which the duct member is created as one unit, NC data of NC10 to NC40 is created as in the lower part of the drawing. Therefore, upon fusing, the deceleration operation had to be performed 16 times as indicated by the circles in the figure, and moreover, the unit length from acceleration to deceleration was short, and the fusing took a long time. Further, the frame Z expands due to the heat effect at the time of fusing and swells in a complicated manner, and in some cases, it may interfere with the portal frame 5 during the fusing.

As described above, according to the present embodiment, by adopting the overlapping edge unifying process, it is possible to superimpose the sides of the adjacent parts, which has been impossible in the past due to the nature of the plasma unit. As a result, the number of fusing lines could be significantly reduced. Also, by adopting the contact edge unification treatment,
The number of decelerations can be reduced and the fusing line can be lengthened,
It enabled a significant speedup. Moreover, the problem of post-processing could be solved by eliminating the need for a frame between the duct members. As a result, according to the present embodiment, it is possible to significantly reduce the number of steps in the fusing process of the duct member.

Further, since the relationship between the duct members melted and blown by the marking process can be understood at a glance, even if the arrangement with a high yield and no frame is provided as much as possible, there will be no trouble in the subsequent distribution. The embodiment of the present invention has been described above,
The present invention is not limited to these examples, and the fusing means may be a fusing device such as a gas or a laser, and can be implemented in various modes without departing from the scope of the present invention. Of course.

For example, the fusing information generating device 30 may be built in the fusing device 1 instead of being placed separately. In that case, it is also possible to set a planing arrangement in the state of the middle part of FIG. 8 externally and then give that information to the fusing device to perform overlap information unification processing and contact information unification processing related to the fusing information. I don't care. That is, the processes of S10 and S20 in the flowchart of FIG.
It suffices if the configuration is such that the processes of to S80 are performed.

Further, the apparatus may be configured so as to execute only either the "overlapping edge unification processing" or the "contact edge unification processing".

[0039]

As described in detail above, according to the apparatus for melting and assembling assembly parts according to the first or third aspect of the present invention, the melting time can be significantly reduced. In the apparatus according to the third aspect, the frame between the assembled parts can be further eliminated, and the post-processing can be simplified. Even in the device according to the first aspect, the frame is divided at the contact point and is not continuous. Therefore, even if the frame expands due to heat, it is merely deformed, and the post-treatment is much easier than before.

Further, according to the assembly component fusing information creating apparatus of the second aspect, the conventional NC fusing apparatus can be the fusing apparatus as described in the first aspect. in addition,
According to the assembly component fusing information creation device of the fourth aspect, the conventional NC fusing device can be the fusing device of the second aspect.
