DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a reinforcing bar machining information providing apparatus and machining information providing program according to the present invention will be described below in detail with reference to the drawings.
The example of the reinforcing bar processing information providing apparatus shown in FIG. 1 detects eigenvector data including absolute position information of the reinforcing bar from data (for example, DXF, IFC format, etc.) created by the 3D CAD software of the reinforcing bar processing book creation device. , To output unique machining data combining machining operations to be applied to the reinforcing bar reflecting the rebar alignment from a plurality of partial attribute information included therein and coordinates forming the part, the CPU, recording means and various The program is provided by installing the reinforcing bar machining information providing program in a computer having an interface.

  This example includes a partial attribute recognition means 1, a straight line evaluation means 2, an arc evaluation means 3, and an editing means 4. The unique machining data is derived according to the flow shown in FIG. Are readable and writable to other recording media and recording devices.

The partial attribute recognition means 1 discriminates a straight line portion and a circular arc portion from the partial attribute information and outputs a straight line code or a circular arc code.
The straight line code is a case where a part to be discriminated from a reinforcing bar (hereinafter referred to as “verification part”) given as 3D vector data including absolute position information is recognized as a straight line as a result of the discrimination process. Similarly, the arc code is a flag or the like that is set when the arc code is recognized as an arc.

In this example, eigenvector data including the shape of the verification portion (partial attribute information) and three-dimensional vector data (coordinates forming the shape) is handled as a conversion target.
In the eigenvector data created by the reinforcing bar integration program, generally, a polygonal line is created with a plurality of alignments arranged continuously with a cross-section list, and a bending region of the reinforcing bar is inscribed in the bending part of the polygonal line. Each linear shape is added as an arc (hereinafter referred to as “arc”), for example, “straight (x1, y1, z1) − (x2, y2, z2), arc (x2, y2, z2)” -(X3, y3, z3)-(x4, y4, z4), straight (x4, y4, z4)-(x5, y5, z5), arc (x5, y5, z5)-(x6, y6, z6) -(X7, y7, z7), direct (x7, y7, z7)-(x8, y8, z8) "(refer to FIG. 3).

Note that non-standard curves other than arcs included in the eigenvector data are converted into arcs subdivided within an allowable error range.
These arcs, for example, divide the curve into n equal parts, create a straight line (hereinafter referred to as “orthogonal line”) extending from the tangent line at the dividing point to the inside of the curve, and 2 at two adjacent dividing points. The radius R ₀ of the arc is derived with the intersection of two orthogonal lines as the center of the arc, and the number n of divisions in which the difference of the radius R ₀ of each arc divided into n is within the allowable value required for the processing of the reinforcing bar material Is treated as eigenvector data positioned as a series of arcs having a radius R derived by the division number n.

The determination processing of the partial attribute recognition unit 1 includes a step of detecting data representing a partial attribute (straight, arc) of the eigenvector data by the processing information providing program, and the partial attribute data is determined in advance. A step of making a determination by making an inquiry, and a step of outputting the straight line code or the arc code based on the inquiry result.
It is possible to adopt a method of detecting a straight line portion from two consecutive coordinates and detecting an arc from three or more consecutive coordinates.

The straight line evaluation means 2 receives the straight line code, derives the length of the straight line portion from the partial attribute information and the coordinates forming the portion, and outputs the reinforcing bar feed code and the reinforcing bar feed data including the feed length.
The straight line evaluation means 2 uses the machining information provision program, for example, to determine the distance between the two from the three-dimensional vector data “(x1, y1, z1) − (x2, y2, z2)” indicating the start and end of the straight line. As the length L of the straight line portion, and one of the operation data included in the operation group data, together with a reinforcing bar feed code (for example, “straight” character data) for providing the straight line portion, ) L ”is expressed as data, and a step of outputting to a recording medium such as a stack is performed.

  The arc evaluation means 3 receives the arc code, derives the radius, circumference angle and turning angle of the arc portion from the part attribute information and the coordinates forming the portion, and rebar bending code and bending angle, bending radius code and bending radius. Reinforcing bar bending data including, and reinforcing bar turning data including a reinforcing bar turning code and turning angle are output.

  The arc evaluation means 3 uses the machining information providing program, for example, three-dimensional vector data “(x2, y2, z2) − (x3, y3, z3) − ( x4, y4, z4) ”, calculating the radius R of the arc formed by each as operation data (operation mode) of the bending operation, deriving the normal N of the arc passing through the center of the arc, A step of deriving the tangent line V at the end point (x4, y4, z4) of the arc and a step of deriving the circumferential angle A of the arc as operation data (operation amount) of the bending operation are performed (see FIG. 2).

Next, the arc evaluation means 3 calculates the relative elevation angle with respect to the portion operated immediately before (the intersection angle between the arc surface normal N ₀ of the immediately preceding arc and the arc surface normal N of the processed arc: arc In consideration of the possibility that a torsion angle of the surface is given, a step of verifying whether or not the arc is the first arc by the machining information providing program, and if the arc is not the first arc, the arc surface method immediately before the line N ₀ is rotated at a tangential V ₀ which that endpoint, the turn angle B as the operation data of the rotation operation (rotation) the normal N ₀ is to face the same direction as the arcuate surface normal N of the validation portion If the verification step is the first arc, the step of setting the turning angle B to 0 degree, and the operation data thus derived are used as a reinforcing bar bending code (for example, “song” character data). , Bending radius code (eg "half" character data) and A step of storing in a recording medium such as a stack is performed with data representing an aspect of “Song A Half R Roll B” together with a rebar turning code (for example, “roll” character data).
The partial attribute recognition unit 1, the straight line evaluation unit 2, and the circular arc evaluation unit 3 check the presence or absence of the subsequent portion and continue the above processing until the subsequent portion does not exist for the inherent linear information.

  The editing means 4 detects, by the machining information providing program, a connection (continuous) between a straight line portion and an arc portion from the partial attribute information of the reinforcing bar determined by the partial attribute recognition means 1 and the coordinates forming the portion; The unique machining data obtained by connecting the reinforcing bar feed data and the reinforcing bar bending data so as to be a combination (operation group data) of all the machining operations to be applied to the reinforcing bars before machining after the connection is expressed as , Music A half-R B, straight L, music A half-R B, straight L, and the like.

[Rebar processing equipment]
The unique machining data contributes to the realization of a reinforcing bar machining apparatus that does not have a database in which the standard alignment is registered.
The reinforcing bar machining apparatus includes, for example, an input means 5 for inputting the unique machining data, a decoder 6 for deriving machining commands and parameters of specific machining operations combined as the unique machining data from the unique machining data, and “ Reinforcing bar feed means 7 that receives a machining command of “straight line formation (straight)” and feeds the amount (the feed length) specified by the parameter of the machining command of “straight line formation” from the starting point of the reinforcing bar material; In response to the processing command of “form (curve)”, the reinforcing bar material at that position has a circumferential angle specified by the parameter of the processing command of “curve formation” and “curve radius setting (half)”. In response to a bending processing means 8 that performs bending forming an arc having a radius specified by a processing command parameter and a processing command of “rebar rotation operation (rolling)”, The turning means 9 for turning the reinforcing bar material at the angle (the turning angle) specified by the parameter of the machining command of the “rebar turning operation”, and the end of the operation for the machining operation combined as unique machining data. The structure which equips with the cutting | disconnection means 10 which cut | disconnects a rebar raw material in the position along the feed track | orbit of a rebar can be taken.

The input means 5 is a reader for reading a two-dimensional information code representing the unique machining data, a reader for reading a recording medium storing the unique machining data, or a keyboard or other input device for manually inputting the unique machining data.
The decoder 6 forms a flag for operating an actuator of a machining means to perform a machining operation based on the machining command, and extracts a parameter attached to the machining command.
The control device of the reinforcing bar feeding means 7, the bending processing means 8, the turning means 9 or the cutting means 10 (hereinafter collectively referred to as “processing means”) specified by the flag performs the processing on the actuator of the processing means. The output which realizes the amount of operation corresponding to the parameter attached to the command is supplied.

For example, as shown in FIG. 6, the reinforcing bar feeding means 7 includes a clamper 11 that can move along the feeding direction of the reinforcing bar material, and a movement amount of the clamper 11 or an operation amount (rotation amount) of the transfer means that moves the clamper 11. And the like. In order to move the clamper 11, a feed guide 15 is installed along the feed direction of the reinforcing bar material, and the clamper 11 is connected to an endless belt 16 that is moved by a servo motor or the like along the feed guide 15. That's fine.
In addition to the above configuration, the reinforcing bar feed means includes a feed length detection means that detects the feed amount of the reinforcing bar via a feed roller and a feed length sensor such as a rotary encoder that detects the rotation angle (rotation speed) of the feed roller. A configuration including a clamper for fixing the position of the reinforcing bar in a state where the set length has been fed can be mentioned.

The bending means 8 is installed, for example, in the feeding direction of the reinforcing bar feeding means 7, and turns around the core shaft 13 arranged at the bending position and the periphery of the core shaft 13 in the bending direction while winding the reinforcing bars. A configuration including the bending roller 14 is employed.
The control device of the bending means 8 sets the turning radius of the bending roller 14 and the turning angle of the bending roller 14 from the parameters of the processing commands of “curve formation (curve)” and “curve radius setting (half)”. Then, by referring to a reference table provided in the control device, the core shaft 13 is changed to the core shaft 13 suitable for the bending work in consideration of the diameter of the reinforcing bar material.

The turning means 9 is a plurality of rollers (preferably three-point holding by three rollers) that can adjust the turning angle to hold the surrounding side surface of the reinforcing bar in an immobile state and turn the reinforcing bar. Is adopted as the clamper 11 of the reinforcing bar feeding means 7.
A feed roller may be adopted as a part or all of the reinforcing bar feeding means 7, and a clamper for holding the reinforcing bar material in an immobile state may be provided separately, and a structure that can release the holding of the reinforcing bar by the clamper during feeding may be adopted. .
The cutting means 10 is provided at the rear of the bending means 8 and, after finishing all the bending work, the distance from the bending position of the bending means 8 to the cutting position of the cutting means 10 at the final straight line portion ( This is cut when the rebar is fed for a length that is the sum of the “discharge distance”).

  For example, the reinforcing bar having the shape shown in FIG. 3 is provided with unique machining data representing “straight L1, music A1 half R1 roll B1, straight L2, music A2 half R2 roll B2, straight L3” and used for the input means 5. The control device of the reinforcing bar feeding means 7 performs a process of feeding the reinforcing bar material to the starting point of the bending process by the clamper 11 of the reinforcing bar feeding means 7 by giving the reinforcing bar diameter of the reinforcing bars to be started.

Therefore, according to the specific machining data, first, the control device of the reinforcing bar feeding means 7 gives a command to feed the L1 length to the actuator.
When the end signal of the L1 length feed operation is output from the feed length sensor, the control device of the bending means 8 receiving it sets the rebar diameter of the rebar material and R1 predetermined core shaft 13, A command to perform a bending operation of A1 degree is given to the actuator.
Since this bending operation is the first bending process for the reinforcing bar material, the turning operation angle B1 in the bending operation is 0 degree (see FIG. 2).

When the end signal of the bending operation of A1 degree is outputted from the bending angle sensor, the control device of the reinforcing bar feeding means 7 receiving it gives an L2 length sending command to the actuator.
When the end signal of the L2 length feed operation is output from the feed length sensor, the control device of the bending means 8 that has received it outputs B2 degrees to the actuator (servo motor, etc.) of the turning means 9. Gives a command to turn (rebar material around its axis). When an end signal of the B2 degree turning operation is output from the turning angle sensor (such as a sensor that detects the rotation angle of the roller constituting the clamper 11), the reinforcing bar diameter of the reinforcing bar material and R2 predetermined core axis 13 is set, and a command for performing a bending operation of A2 degrees is given to the actuator.

When the end signal of the bending operation of A2 degrees is output from the bending angle sensor, the control device of the reinforcing bar feeding means 7 receiving it gives a command to send L3 length to the actuator.
Finally, when a feed operation end signal having a length obtained by adding the discharge distance to the L3 length is output from the feed length sensor, the control device of the cutting means 10 instructs the actuator to perform a cutting operation. give.
By adopting a rebar processing device with such a configuration, it is not necessary to have a database in which a standard alignment with a shape code is registered, and it is desired from a simple shape to a complex shape according to the rebar shape request. Can be bent without complicated work.

  The unique processing data may be printed on a pictograph or the like by adding a two-dimensional information code conversion module to the processing information providing device and converting the content of the unique processing data into a two-dimensional pattern representing a character string. it can.

Since the unique machining data written in the two-dimensional information code is easy to convert as described above and has high versatility, the data that can be read by the reinforcing bar machining apparatus via the two-dimensional information reading module is, for example, It can supply after converting as follows (refer FIG. 5).
When it is required to restore the eigenvector data from the eigenprocessing data, the eigenvector data includes a starting point position P, a starting point direction V of the eigenvector data, and an initial arc surface normal line connected to the starting point. N may be added in a manner such as “position (Px, Py, Pz) direction (Vx, Vy, Vz) method (Nx, Ny, Nz)”.
