Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a copying apparatus including a copying tool that two-dimensionally follows and follows the contour of a base body.

[0002]

[Prior art]

 Generally, the Ebonus process, in which various designs of letters and patterns are displayed in relief on the fabric for apparel in a concavo-convex shape, is shown in the figure. By placing a material such as cloth that can be thermally deformed between the elastic heating floor to be installed, and pressing the material between them for a predetermined time (several seconds to several tens of seconds), the figure can be drawn. It is manufactured by molding it into a concave and convex shape. Conventionally, an NC processing machine is used to manufacture the mold used for the above embossing, and the figure engraved on this mold is entered in the end mill shape by inputting the figures in which the outline of the master is described in numerical figures. The workpiece is cut by the two-dimensional operation of the blade.

As a simple engraving device, a manual copying device in which a copying tool and a rotary tool are connected by an expansion / contraction link member is used, and the copying operation of the copying device is performed by first copying the contour of the prototype to a copper plate or the like. A link member is produced by copying on a plate surface, etching the surface, and manufacturing a base body having an irregular contour, and moving the copying tool to follow the contour step portion of the figure engraved on the base body. It is known that a rotary tool is two-dimensionally operated at a desired scale via a tool to engrave the contour shape of a substrate.

[0004]

[Problems to be solved by the device]

 However, in the die machining by the conventional NC machining machine described above, operation of a complicated machining machine requires specialized skill, and complicated work and a lot of time are required for inputting the figure numerical value, and the manufacturing cost is high. However, there is a drawback that the cost becomes high. In addition, in the above-mentioned manual copying device, if the copying device is moved following the flat drawing directly, the accuracy is lacking, so that it is necessary to separately manufacture a base body that guides the copying device. There are problems such as being expensive and taking a long time to work. Further, in the above means, since the copying operation and the die engraving of the copying tool are manually performed, the work is complicated, requires a high degree of skill, and makes deep engraving difficult. There is a problem that it is unsuitable for manufacturing an embossing mold for apparel that requires the use of a mold.

In the field of apparel, which is very popular, due to small lot production of graphic designs, design changes, etc., the molds used therefor often change in the middle, and it is necessary to manufacture many molds. High-priced molds and manufacturing methods that take a long time to manufacture, such as conventional ones, are inappropriate. Therefore, the present invention solves the above-mentioned problems of the prior art and allows a copying apparatus to directly copy a copying machine onto a substrate such as a drawing, thereby enabling an accurate copying operation to be performed efficiently and inexpensively. It is the one we are trying to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the copying apparatus according to the present invention proposes a pen shaft-shaped copying tool 4 which is moved following a base body K having a contour of a prototype and a movement of the copying tool 4 which regulates a two-dimensional direction. A horizontal axis 5 and a vertical axis 6 are included therein, and a detector 9 for detecting the two-dimensional movement amount of the copying tool 4 is provided, and the copying section 46 that is moved to follow the contour of the prototype of the base body K and the copying section. It is composed of an adjusting portion 45 for adjusting the amount of vertical movement of 46 and a holder 42 for supporting the copying portion 46 so that it can move up and down with respect to the base body K. The copying tool (4) is preferably configured such that the copying section 46 can be inserted into and removed from the holder 42 and replaced.

[0007]

[Action]

 Since the present invention is constructed as described above, the copying tool 4 can be smoothly moved along the contour of the base body K while being guided and supported by the horizontal axis 5 and the vertical axis 6. The two-dimensional movement amount is accurately detected by the detector 9. At this time, the copying tool 4 formed in the shape of the pen shaft is easy to grasp, so that the follow-up operation can be accurately performed with a handwriting feeling, and the copying section 46 can be adjusted up and down to avoid contact with the base body K. It is possible to prevent damage to both of them, and to separate the copying section 46 from the base body K at a height at which the operator can most easily perform the copying operation with high efficiency. Further, in the machining work of the tool T which needs to be replaced and the copying work thereof, since a proper number of copying parts 46 having the same actual size as the various tools T are prepared and can be easily replaced by inserting / removing into / from the cylindrical shaft-shaped holder 42, As shown in FIGS. 5A to 5D, even with the tool T and the copying section 46 having different radii r and R, the outer circumference of each copying section 46 follows the contour of the prototype diagram K1. Therefore, each tool T can be machined to have the same contour as this, and the copying operation can be accurately performed as it is without the need to correct the detected numerical value or special operation.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In FIG. 1 and FIG. 3, A is a copying machine including a copying machine 1, a controller 2 for processing data sent from the copying machine 1, and a processing machine 3 operated by the command thereof. A base body K having a reference drawing, a pictorial diagram, or a contour of a prototype as a reference of a copying member such as a pattern paper or a model depending on the configuration is installed on the base plate 1a of the copying apparatus 1, and the contour shape of the base body K is set. The two-dimensional movement amount in the vertical and horizontal directions and the combined direction of the release tool 4 which can be manually traced along the line is converted into an equal amount or an enlarged or reduced movement amount and set in the processing machine 3. The work W to be cut is automatically cut by the tool T to perform a die carving work.

As shown in FIG. 2, the copying apparatus 1 is provided with a flat base plate 1a on a frame 1b on which a drawing or an appropriate model object can be placed, and metal 5a, 5a at the upper and lower four corners thereof. .. are fixed to support the horizontal shafts 5 and 5, and the slide blocks 5b and 5b are slidably fitted in the horizontal shafts 5 and 5, and the vertical axes are attached to the slide blocks 5b and 5b. Both ends of 6 are supported, and are mounted separately from the base plate 1a so as to have a moving space. A slide block 7 which is slidable in the vertical direction is fitted on the vertical axis 6, and a copying tool 4 formed in a pen shaft shape is erected on the side surface in the vertical direction via a mounting arm 41 and a screw 41a. It is detachably attached.

Further, as shown in FIG. 5, the copying tool 4 is slidably fitted with a copying piece 43 with a copying part 46 in a cylindrical holder 42 supported by a mounting arm 41, without rattling. At the same time as inserting, the copying piece 43 is detachably attached with a screw rod (adjusting portion) 45 with a knob 44 and the mounting height is adjustable, and a pin-shaped copying portion 46 formed at the lower end portion is attached. The lower end portion is positioned so that it is close to the base body K, and the vertical movement is allowed when the base body K comes into contact with the base body K. The copying section 46 contacts the base body K to cause damage to both. In addition, the copying operation can be easily carried out by providing a work posture in which the base body K can be easily operated for follow-up.

Further, as shown in FIG. 2A, the diameter of the copying portion 46 is the same as the diameter of the end mill-shaped blade (tool T) when it has a small diameter. When it has a large diameter, it is formed on the copying tool 4 having a pin diameter as large as this. As a result, the contour of the prototype base body K such as the actual object or the pattern paper shown by the dotted line or the diagram K1 drawn in the drawing is directly made by the copying section 46 formed in the same actual size as the various blades T for cutting the work W. Tracing, two-dimensional follow-up movement in the vertical and horizontal directions, and the combined direction (hereinafter referred to as “following”) to obtain the same precision as the actual machining tool T, and the tool T at each cutting location This makes it easy to study the conversion, and it is possible to easily perform the follow-up copying work in this case.

Reference numerals 8 and 8a denote linear scales having a distance measuring element, which are provided in parallel with the vertical axis 6 and the horizontal axis 5. The vertical linear scale 8 is supported between the slide blocks 5b and 5b and The linear scale 8a in the direction supports both ends between the metals 5a and 5a. Position detectors (detectors) 9 and 9a fixed to the slide block 7 and the slide block 5b are slidably fitted in the linear scales 8 and 8a. Then, the distance when the detectors 9 and 9a move on the linear scales 8 and 8a is read by the distance measuring element to detect the distance, which is displayed on the display unit 9b and the read value is detected. The signal is sent to the control device 2 as a signal. Reference numeral 9c is a setting switch installed in the detectors 9 and 9a. By pressing this, the detection data is cleared and the origin (0 point) is set (at this time, the display section 9b displays 0). The two-dimensional movement amount of the copying tool 4 from the above is transmitted to the control device 2. Further, 9e is a power switch for turning the copying apparatus 1 and the control apparatus 2 ON and OFF, and 9d is a signal adjusting switch.

Further, a set switch 10 for address-transferring the signal to the control device 2 and a reset switch 10a for releasing the signal are provided at both lower ends of the frame 1b so as not to be erroneously operated during manual operation. By operating both switches 10 and 10a, the work W mounting base 3a of the processing machine 3, which will be described later, is two-dimensionally operated in the vertical and horizontal directions and the combined direction according to the command signal. Reference numerals 11 and 11a are Y lines and X lines which are connected to the harnesses of the linear scales 8 and 8a and the switches 10 and 10a to send the detection data to the control device 2, and are input to the positioning CPU 2a of the control device 2. ing. The positioning CPU 2a includes a data complementing section 21, a data control section 22 and a memory section 23 to process the detected data, activate the tool T simultaneously with the operation of the copying tool 4, and delay the tool T by a time delay. It is possible to operate with.

Then, the data processed by the positioning CPU 2a is sent to the servo controller 2b and is signal-processed through the integrated control unit 24, the drive pulse amplifier 25, the comparator 26, etc., and the signal is the vertical axis motor power signal line. A vertical axis motor 31 installed on the processing machine 3 is rotated forward and backward and variably by 27, and a horizontal axis motor 32 is rotated forward and backward and variably by a horizontal axis motor power signal line 28. Numerals 27a and 28a are servo lines for sending encoder pulse signals transferred from the encoders 31a and 32a installed on the vertical axis motor 31 and the horizontal axis motor 32, respectively, to the comparator 26 and the positioning CPU 2a, which constitutes a servo mechanism. is doing. This servo mechanism detects the position when the tool T is cutting the work W and gives a correction instruction to both the motors 31 and 32 so that accurate machining can be automatically performed. Even if the resistance changes or the material of the work W partially changes in cutting resistance, it is possible to appropriately cope with the change.

Next, FIG. 4 showing an embodiment of the processing machine will be described. In this embodiment, the processing machine 3 is a milling machine in which a milling cutter (tool) T is detachably held by a vertical axis chuck 34 of a motor (driving unit) Z supported by a column 33. The processing machine 3 is provided on the bed 35 so as to be horizontally movable by screwing the work table 36 onto the horizontal screw rods 35a, 35a axially supported along the bed 35. The mounting base 3a of the work W engaging with the dovetail groove is screwed onto the vertical screw rod 36a so as to be vertically movable. A vertical axis motor 31 and a horizontal axis motor 32 are provided at the ends of the vertical screw rod 36a and the horizontal screw rod 35a, respectively, and these are rotatably forwards and backwards rotatably in accordance with a command from the control device 2 to provide a mount (support portion). 3a is adapted to move relative to the tool T two-dimensionally in the vertical and horizontal directions and the synthesis direction.

Reference numeral 37 is a drive pulley fixed to the motors 31 and 31, 37a is a driven pulley fixed to the screw rods 36a and 35a, and belts 38 and 38 are stretched between them. Constitutes the transmission mechanism. Further, a control device 2 connected to the copying device 1 described above is installed inside a machine frame 39 on which the bed 35 is placed. Further, the work W to be engraved and cut is detachably fixed to the mounting base 3a with the bolts 3b through the mounting holes W1 formed at appropriate positions of the work W. The tool T is configured so that it can be moved up and down, and the excavation depth of the work W can be set arbitrarily. Further, the tool T is provided with a detection tool (not shown) for detecting the vertical movement of the copying tool 4 of the copying apparatus 1 and is connected through the control device 2 so that vertical and horizontal processing as well as vertical three-dimensional processing can be performed. It may be possible to perform three-dimensional processing.

Next, for one mode of use of the embodiment of the present invention having the above-described structure, a work W of a mold is manufactured based on the base body K of FIG. 6A, and the cloth is embossed using the work W. The case will be described. The substrate K of FIG. 3A is a drawing in which a contour of a design or the like having an appropriate design is drawn on a sheet by a diagram K1. As shown in FIGS. 2 and 3, the base body K is attached to an arbitrary position on the base plate 1a made of the magnet board of the copying apparatus 1, and the copying section 46 is positioned inside or above the diagram K. After adjusting the height, the power switch 9e and the setting switch 9c are turned on to set the origin 0, and the holder 42 is operated in an operation posture such that the pen shaft is gripped, and the line K1 It traces two-dimensionally along the contour locus of the object.

At this time, the two-dimensional movement amount of the copying tool 4 is detected by the detector 9 and sent to the control device 2, and is stored until the setting switch 9c is pushed again and the origin is set. Next, by turning on the set switch 10, the rotary tool T of the processing machine 3 causes the work W mounted on the mounting base 3a to move the workpiece W mounted on the mounting base 3a to the vertical axis motor 31 and the horizontal axis motor 32 according to the command from the control device 2. By operating in the vertical and horizontal directions as well as in the composite direction, the die-cutting work with a predetermined depth is automatically performed according to the shape of the diagram K1 of the set size. Further, the stop can be stopped during the processing operation by pushing the reset switch 10a, and the re-operation of the set switch 10 enables the continuous operation after the operation again. Therefore, the tool (tool) T can be exchanged easily and appropriately at a desired place during the machining operation. Further, the machining of the central portion of the diagram K1 can be easily performed by linearly reciprocating the copying tool 4.

Further, as shown in FIG. 2, the diagram K1 is divided into, for example, points a, b, c, ... For each curvature of the line segment, and the origin of the detector 9 is set at the divided points each time. It is also possible to operate the processing machine 3 for each section by the control device 2. In this case, since the control device 2 can be manufactured without increasing the storage capacity of the detected data, the device can be made inexpensive, and the replacement time of the tool T can be freely set for each section. Therefore, there is an advantage that accurate machining work can be easily performed. It should be noted that it is convenient to notify the operator of the replacement time of the tool T by a notification means (not shown) such as a buzzer separately installed in the necessary section.

Further, in the machining work of the tool T that needs to be replaced and the copying work thereof, the copying unit 46 is simply replaced with one having the same actual size as the various tools T and set in the copying tool 4, 5 (A) to (D), even with the tool T and the copying section 46 having different radii r and R and different sizes, the outer circumference of each copying section 46 follows the contour of the diagram K1. Therefore, each tool T also accurately processes the same contour. Therefore, accurate copying work and machining work can be easily performed without correction of detected values and special operations, and a series of copying work can be efficiently performed in addition to the work for each section. it can. Further, it is possible to operate the copying tool 4 formed in the shape of a pen shaft on the base plate 1a in the form of a pen shaft with a contour having a complicated pattern or a figure having various curvatures, so that no skill is required. Anyone can easily and precisely manufacture a low-cost mold efficiently. Therefore, we were able to optimize it as a simple and inexpensive embossing type, which is required in the apparel field, where there are many other types of small-quantity production and half-way type changes.

As shown in FIG. 6, the work W, which has been subjected to the die-cutting process in this manner, is removed from the mounting base 3 a and the concave portion K2 die-cut in the shape of the diagram K1 is pressed downward in a pressing machine. It is screwed to the ascending / descending base 50 of P through the mounting hole W1 ((C) in the same figure). The press P has a heater 51 inside the lift 50 to conductively heat the work W, and a heater 54 is installed inside a resilient receiving floor 53 installed below to heat the work. While heating the material S inserted between the two, it is pressed as shown in FIG.

As a result, as shown in FIGS. 7E and 7F, the material S is formed into a convex figure K3 by projecting its surface toward the concave portion K2. Therefore, the material S to be embossed by the work W manufactured as described above can be manufactured inexpensively because the material S is formed to have the same shape as the base body K and is appropriately protruded. In the field of apparel, the material S is made of a thermoplastic cloth, a plastic film material, a thickly treated member, or the like. In other fields, a plate-like material made of an arbitrary material suitable for a press die is appropriately selected and processed.

Next, a second embodiment of the copying apparatus 1 will be described with reference to FIG. In this copying apparatus 1, a drive member (screw rod) 61 having a drive motor 60 at its shaft end is rotatably supported between the slide blocks 5b, 5b and provided parallel to the vertical axis 6, and a drive motor 62 is provided. A member (screw rod) 63 is supported between the metals 5a, 5a and provided in parallel with the horizontal axis 5. Further, the slide block 7 which has the copying tool 4 and is slidably fitted to the vertical axis 6 is provided with a rolling block provided in the slide block 7 in a state in which the screw rod 61 is rotatably fitted in the inner portion of the other side. The moving ball 64 is engaged with the thread groove 65, and the slide block 5b slidably fitted to the one horizontal shaft 5 is also inserted into the threaded rod 63 by ball engagement in the same manner as described above.

Further, the drive motors 60 and 62 are respectively connected to the servo lines 27a and 28a of the control device 2 described above in FIG. 1 and provided with encoders (sensors) 60a and 62a connected to the drive control unit 2c indicated by the dotted line. At the same time, detectors 9 and 9a having a display unit and respective operation switches are provided. With the above configuration, when the copying tool 4 is gripped and starts to move in the vertical direction of the arrow along the line K1, the threaded groove 61 of the screw rod 61 is pressed against the slope of its lead angle via the rolling ball 64. The encoder 60a detects a rotational force component as a pressing force sensor, and transmits it to rotate the drive motor 60 to rotate leftward in the direction of the arrow. Therefore, the screw rod 61 is rotated in the same direction while the force in the direction of the arrow is lightly applied to the copying tool 4, so that the slide block 5b is driven by the screw rod 61 to move, whereby the copying tool is moved. It is possible to perform the follow-up work lightly without requiring a great deal of force for the secondary movement operation of 4 or moving too fast.

Further, when the copying tool 4 is moved in the opposite arrow direction opposite to the above, since a reverse rotational component force is applied to the screw rod 61 via the rolling balls 64, the encoder 60a operates accordingly. Is detected, the screw rod 61 is rotated to the right, and the slide block 7 is urged so as to move vertically downward to facilitate the vertical follow-up operation of the copying tool 4. Further, the copying tool 4 can be biased and driven in the same manner as in the vertical direction with respect to the lateral movement in the lateral direction. As a result, according to the present embodiment, the follow-up work of the copying tool 4 can be smoothly performed by urging the driving motors 60 and 62 in the vertical and horizontal directions and the combined direction, and the excessive copying of the copying tool 4 can be braked. It is possible to precisely control and maintain an appropriate cutting speed. Therefore, even in the case of the complicated diagram K1, a light follow-up copying operation can be performed without requiring a large operating force as compared with the first embodiment, and the copying tool 4 is accurate and efficient without overshooting. The copying work and the work W can be processed.

The biasing drive mechanism described above can also be adopted in the configuration of the first embodiment. In this case, the vertical axis 6 and the horizontal axis 5 do not serve as drive members, and a screw rod similar to that of the second embodiment is used. By providing a rolling ball engaging mechanism and the driving motors 60 and 62 with encoders, the same follow-up work of the copying tool 4 as in the second embodiment can be performed. As the driving member, a fluid cylinder with a servo valve or the like may be used instead of the screw rod. In the above-described embodiment, the processing machine 3 transmits the data of the copying apparatus 1 to the vertical axis motor 31 and the horizontal axis motor 32 via the control unit 2 to operate the mounting base 3a for mounting the workpiece W. Without being limited to this, contrary to the above, the work W is in a state of being fixedly supported on an appropriate supporting member (not shown) or the ground, and the motor having the tool T provided to face the work W ( The drive unit) Z may be two-dimensionally controlled and moved with the same configuration as described above.

In this case, it can be optimized for excavating or engraving a picture on a long and heavy object such as a tombstone or a stone material of a lantern. A sand shot nozzle, a jet chisel or the like is appropriately used as the tool T used for processing the stone material. Further, the configuration of the present invention can be applied to various industrial processing machines. Depending on the shape of the work W, the material, and the like, the tool T can be selected from various tools such as gas, laser, etc., in addition to blades. It performs mechanical processing (cutting, cutting, fusing, grinding, etc.).

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. The copying tool can be smoothly moved along the contour of the base body while being guided and supported by the horizontal and vertical axes, and the two-dimensional movement amount of the copying tool can be accurately detected by the detector. it can. At this time, the copying tool formed in the shape of the pen shaft is easy to grasp, so that the follow-up operation can be accurately performed as if it were a handwriting operation. In addition to preventing damage, the copying part can be separated from the base body at a height at which the copying part can be visually operated by an operator and is most easily operated, thereby performing a copying process with high efficiency. In addition, in the machining work of tools that require replacement such as die-cutting and copying work, prepare a suitable number of copying parts with the same actual size as various tools, and insert and remove them in a pen-shaped holder to easily replace them As a result, even tools with different radii and shapes can be accurately detected as they are without the need to correct the detection number and special operations, and the copying operation can be performed efficiently.
