Description

  The present invention relates to an automatic three-dimensional molding apparatus for wiring members for electrically connecting electrical appliances arranged in a panel such as a control panel or a distribution board, and in particular, based on wiring route data stored in advance in a control apparatus. The present invention relates to an apparatus for three-dimensionally driving a wiring forming machine and forming a wiring material into a required three-dimensional shape outside the panel.

  A number of electrical appliances such as terminal blocks, breakers, and switches are set in a panel such as a control panel or switchboard, and these electrical appliances are electrically connected to each other using a number of wiring materials. Yes. In order to efficiently route a large number of wiring materials in a narrow panel, the wiring route of each wiring material must be set appropriately. There is also a need to form the film. In some cases, it is also necessary to divide the routing depending on the circuit classification, the presence or absence of a duct, and the like. As described above, in-panel wiring such as control panels and switchboards has many restrictions and is difficult to automate, and therefore still depends on the skill of the operator.

  That is, most of this type of wiring work is performed by an operator while looking at the wiring diagram. In this case, the operator repeats the work of terminal attachment, wire number attachment, origin fixation, routing, temporary fixation, and landing confirmation from the starting point for the required number of wires, and finally adjusts the wire to a duct, etc. Since the work of fixing must be performed, the efficiency of the wiring work depends on the skill of the operator. In addition, a method of preparing a necessary length of wiring material in which both terminals and both wire numbers are attached before starting the wiring work in advance and performing necessary wiring using this is also known in the past. Even if such a method is used, the routing must be performed by the worker based on the wiring diagram, so the dependence on the skill of the worker is not alleviated, and the efficiency improvement effect of the wiring work is insignificant. Stay on.

  As another method, a method of forming a wiring material having a predetermined shape by using an automatic forming apparatus and facilitating a routing operation at the time of wiring is also known. As a wiring material automatic forming apparatus applied to this type of wiring method, a board-like model called a wiring board or foam board is provided, and the board-like model is erected in the required arrangement on the surface of the board model. There is a positioning pin that uses a wiring head operable in a three-dimensional direction to wind an electric wire fed from a reel in a predetermined order and in a predetermined direction (for example, see Patent Documents 1 and 2). According to the devices described in Patent Documents 1 and 2, a two-dimensional wiring material can be formed with high accuracy and high efficiency, and the two-dimensional wiring material can be used as a two-dimensional wiring route. In the case of application, the molded wiring material can be used as it is, and the routing work can be omitted. Therefore, a remarkable effect can be expected in improving the efficiency of the wiring work.

  However, since the devices described in Patent Documents 1 and 2 can only form a wiring material into a two-dimensional shape, when this two-dimensional shape wiring material is applied to a three-dimensional wiring route, The worker must rework the two-dimensional wiring material into a three-dimensional shape, and the effect of improving the work efficiency is limited. Moreover, although the apparatus of patent document 1, 2 requires the plate-shaped model called a wiring board or a foam board, it shape | molds the wiring material of the two-dimensional shape applicable to a three-dimensional wiring route. Therefore, since it is necessary to arrange the positioning pins in consideration of the three-dimensional wiring route, a great deal of labor is required to produce the plate-like model. For this reason, in order to reduce the cost of power distribution equipment such as control panels and power distribution boards, the only effective way is to use wiring as a harness and rely on overseas production with low labor costs.

  The present invention has been made in view of such a state of the art, and the object thereof is to automatically form a three-dimensional wiring material, thereby reducing the cost and quality of power distribution equipment. An object of the present invention is to provide a wiring material automatic three-dimensional molding apparatus capable of achieving the above.

  In order to solve the above-described problems, the present invention provides a wiring forming machine, a control device that outputs a control signal corresponding to the input wiring route shape and controls the driving of the wiring forming machine, and the wiring forming machine.

  According to this configuration, the wiring forming machine repeats the transfer of the wiring material and a predetermined amount of bending in a predetermined direction in accordance with the feed amount control signal, the bending amount control signal, and the bending direction control signal output from the control device. Thus, a wiring material formed into a required two-dimensional shape or three-dimensional shape can be produced without requiring a plate-like model called a wiring board or a foam board.

  According to the present invention, in the wiring material automatic three-dimensional forming apparatus having the above-described configuration, the wiring route shape is automatically designed using a panel wiring support system.

Thus, the manufacturing efficiency of the control panel or the wiring board can be increased.

  In the wiring material automatic three-dimensional molding apparatus having the above-described configuration, the wiring material supply device supplies a wiring material having a predetermined length corresponding to the desired wiring route shape to the wiring forming machine. And

  According to this configuration, since the handling of the wiring material can be facilitated as compared with the case of handling the long wiring material wound around the reel, the forming of the wiring material can be facilitated. In addition, since it is not necessary to provide a wiring material cutting device in the wiring forming machine, the configuration of the wiring forming machine can be simplified.

  Further, the present invention is the wiring material automatic three-dimensional forming apparatus having the above-described configuration, wherein the wiring material forming mechanism is configured such that the wiring material is interposed via a support roller and a bending roller that sandwich the wiring material, and a support roller and a bending roller. And an elastic member that applies a predetermined clamping pressure to the bending roller, wherein the bending roller revolves while rotating around the support roller when the wiring member is bent.

  When the wiring material is bent in a state in which the wiring material is sandwiched between a pair of rollers and a predetermined clamping pressure is applied to the wiring material via one of the rollers, there is no clearance between the wiring material and the roller. The wiring material can be accurately formed into a predetermined shape. In addition, if the wiring material is bent using a support roller and a bending roller, the roller can be rolled along the surface of the wiring material during the bending process, so that an excessive tensile force or frictional force is applied to the wiring material. It does not act, and damage and disconnection of the insulating coating can be prevented.

  According to the present invention, in the wiring material automatic three-dimensional forming apparatus having the above-described configuration, the supporting roller and the bending roller are arranged such that the supporting roller having a small diameter is disposed on the rotation center side of the wiring material forming mechanism with respect to the rotating mechanism, and The bending roller having a large diameter is provided on the opposite side of the bending roller.

  According to such a configuration, the bent portion of the wiring material can be formed into a sharp shape, the tensile force and the frictional force acting on the wiring material can be further reduced, and the insulation coating can be more reliably prevented from being damaged or disconnected. .

  According to the present invention, the wiring material transfer mechanism, the wiring material forming mechanism, and the rotating mechanism provided in the wiring forming machine are driven in accordance with the control signal output from the control device, and the wiring material corresponds to the wiring route shape. Since it is formed into a shape, a wiring model formed into a required two-dimensional shape or a three-dimensional shape can be automatically produced without requiring a plate-like model called a wiring board or a foam board. Therefore, the wiring material can be divided into parts outside the panel, the wiring work that has become a bottleneck when manufacturing the control panel, the switchboard, and the like can be facilitated, and a significant man-hour reduction effect can be expected. Further, by making the parts, it is possible to reduce the labor of the operator, to realize a low skill in the wiring work, and to further stabilize the wiring quality.

Further, the first member 10a and the second member 10b are provided with a through hole 10d through which the wiring member 2 is inserted, and the wiring transferred from the wiring member transfer mechanism 21 through the through hole 10d. The material 2 can be supplied to the wiring material forming mechanism 23.

  The wiring member forming mechanism 23 includes a U-shaped forming mechanism holding bracket 7 attached to the second member 10b of the rotating body 10, and a bending arm 4 having one end pivotably attached to the forming mechanism holding bracket 7. , A bending roller driving member 5b movably disposed in the bending arm 4, a bending roller mounting shaft 5a and a spring 5c attached to the bending roller driving member 5b, and rotatable on the outer periphery of the bending roller mounting shaft 5a. The bending roller 5 is attached to the bending arm 4, the supporting roller 6 is attached to the bending arm 4, and the bending motor 17 is driven to rotate the bending arm 4.

  The board wiring support system 3 uses CAE software to automatically design the wiring route shape from the board wiring sequence drawing, component arrangement information, etc., and commercially available CAE software can also be used.

  The control device 11 converts the coordinates of the wiring route shape supplied from the board wiring support system 3 via the connection cable 3 a into the coordinates of the wiring forming machine 1, and the feed amount as a control signal of the wire feeding motor 14. A control signal, a bending direction control signal that is a control signal for the rotating body driving motor 15, and a bending amount control signal that is a driving control signal for the bending motor 17 are output.

  For example, as shown in FIG. 5, a wiring forming machine 1 is formed by connecting a wiring material 2 restricted in a three-dimensional shape of an XYZ mounting coordinate system in which sides 1 to 5 are bent at right angles at bending points 1 to 4. , The XYZ mounting coordinate system, which is the coordinate system of the board wiring support system 3, is converted into the SUV bending coordinate system, which is the coordinate system of the wiring forming machine 1, and the necessary feed An amount control signal, a bending direction control signal, and a bending amount control signal are output. Below, the example of the coordinate transformation performed in the control apparatus 11 is demonstrated using FIG. 6 thru | or FIG. The coordinate conversion procedure is the same when the machining start point is the starting point shown in FIG. 5 or when it is the landing point. However, in the following description, a case where coordinate conversion is performed from the starting point is taken as an example. Let it be an explanation.

  In the example of FIG. 6A, the starting point, the bending points 1 to 4 and the landing point are coordinate-converted from the bending point 1 of the mounting coordinate system to the origin of the bending bending coordinate system. In this example, the origin is when the bending arm 4 is vertically upward (state shown in FIG. 3). In the example of FIG. 6B, the starting point, the bending points 1 to 4 and the landing point are coordinate-transformed so that the side 2 is on the S axis. Furthermore, in the example of FIG. 6C, the start point, the bending points 1 to 4 and the landing point are coordinate-transformed so that the side 1 is on the V axis and the starting point is in the negative direction of the V axis. .

  7 performs coordinate conversion using the coordinates of the starting point, the landing point, and the bending points 1 to 4 converted in FIG. In FIG. 7A, the bending point 2 is coordinate-converted to the origin of the bending processing coordinate system, and the starting point, bending points 1, 3 to 4, and the landing point are also coordinate-converted under the same conditions. Further, in FIG. 7B, the side 3 is coordinate-transformed to be on the S-axis, and the origin, the bending points 1 to 4 and the landing point are coordinate-transformed under the same conditions. In FIG. 7B, the bending direction is determined from the coordinates of the bending point 1 and is bent in the positive direction of the V-axis.

  FIG. 8 performs coordinate conversion using the coordinates of the starting point, landing point, and bending points 1 to 4 converted in FIG. In FIG. 8A, the bending point 3 is coordinate-converted to the origin of the bending coordinate system, and the starting point, the bending points 1, 2, 4 and the landing point are coordinate-converted under the same conditions. In FIG. 8 (b), the side 4 is coordinate-transformed to be on the S-axis, and the origin, the bending points 1 to 4 and the landing point are coordinate-transformed under the same conditions. In FIG. 8B, the bending direction is determined from the coordinates of the bending point 2, and bending is performed in the negative direction of the U axis. Also in FIG. 9, the bending direction is determined similarly to FIG. The control signal of the wiring forming machine 1 can be automatically created by the sequence as described above.

  As a wiring material supply device (not shown) for supplying the required wiring material 2 to the wiring forming machine 1, a device that sequentially supplies a long wiring material wound around a reel to the wiring forming machine 1 from its front end side is used. Alternatively, it is also possible to use the one that supplies the wiring forming machine 1 with the wiring material 2 cut to a predetermined length according to the desired wiring route shape. When the latter wiring material supply device is used, the wiring material 2 can be easily handled as compared with the case where the long wiring material 2 wound on the reel is handled, so that the forming of the wiring material 2 is facilitated. Can do. Moreover, since it is not necessary to provide the wiring forming machine 1 with a cutting device for the wiring member 2, the configuration of the wiring forming machine 1 can be simplified.

  Hereinafter, the operation of the wiring forming machine 1 will be described.

  When the wiring material 2 is supplied from a wiring material supply device (not shown) to the wiring material transfer mechanism 21 of the wiring forming machine 1 and the leading end thereof reaches between the driving side electric wire feeding roller 12b and the driven side electric wire feeding roller 12c, The motor 14 is started, and the wiring member 12 is transferred to the rotating mechanism 22 side by the driving side electric wire feeding roller 12b and the driven side electric wire feeding roller 12c. The transfer amount of the wiring material is controlled by a feed amount control signal output from the control device 11. As a result, the wiring material 2 that has passed through the driving-side electric wire feeding roller 12b and the driven-side electric wire feeding roller 12c passes through the through hole 10d provided in the rotating body 10 and the bending roller 5 provided in the wiring material forming mechanism 23. It reaches between the support rollers 6.

  Simultaneously with the transfer operation of the wiring member 2, the rotating body driving motor 15 is driven in accordance with the bending direction control signal output from the control device 11. The rotational force of the rotating body driving motor 15 is transmitted to the wiring material forming mechanism 23 via the gear 16 and the rotating body 10, and the rotational direction position of the wiring material forming mechanism 23 with respect to the wiring material transfer mechanism 21 is adjusted. Since the bending arm 4 of the wiring material forming mechanism 23 is disposed at the vertically upward origin position when the wiring forming machine 1 is started, coordinate conversion is performed so that the first bending process bends the wiring material 2 vertically downward. In the case where it is done, it is not necessary to adjust the rotational direction position of the wiring material forming mechanism 23 at the time of the first bending.

  Next, the bending motor 17 is activated, and the wiring member 2 is bent by a bending amount corresponding to the bending amount control signal output from the control device 11 in a direction corresponding to the bending direction control signal output from the control device 11. . When the bending motor 17 is started, the rotational force of the bending motor 17 is transmitted to the bending roller 5 via the bending roller mounting shaft 5a, and the bending roller 5 rotates around the support roller 6 along the wiring member 2. While revolving. As a result, the wiring material forming mechanism 23 moves from the state shown in FIG. 3 to the state shown in FIG. Since the bending roller 5 applies a predetermined clamping pressure to the wiring member 2 by the elastic force of the spring 5c, there is no clearance between the wiring member 2 and the bending roller 5 during bending, and the wiring member 2 Can be accurately formed into a predetermined shape. In addition, since the bending roller 5 and the supporting roller 6 roll along the surface of the wiring material 2 during bending, excessive tensile force and frictional force do not act on the wiring material 2 to prevent the insulation coating from being damaged or disconnected. can do. Further, since the large-diameter bending roller 5 revolves around the small-diameter support roller 6, the bent portion of the wiring material 2 can be formed into a sharp shape, and the tensile force and friction acting on the wiring material 2 can be formed. The force can be further reduced, and damage or disconnection of the insulating coating can be prevented more reliably.

  Thereafter, the wiring material 2 is formed into a predetermined two-dimensional shape or three-dimensional shape by repeating the same operation.

  The wiring material automatic three-dimensional molding apparatus according to the present embodiment drives the wiring material transfer mechanism 21, the rotation mechanism 22, and the wiring material molding mechanism 23 provided in the wiring forming machine 1 according to a control signal output from the control device 11. Since the wiring material 2 is formed into a shape corresponding to the wiring route shape, a wiring material formed into a required two-dimensional shape or three-dimensional shape without the need for a plate-like model called a wiring board or a foam board is required. Can be created automatically. Therefore, the wiring material 2 can be made into parts outside the panel, the wiring work that has become a bottleneck when manufacturing a control panel, a switchboard, etc. can be facilitated, and a significant man-hour reduction effect can be expected. . Further, by making the parts, it is possible to reduce the labor of the operator, to realize a low skill in the wiring work, and to further stabilize the wiring quality.
