Description

CNC lathe of the workpiece management system

This invention relates to a workpiece management system of a C & C lathe. For more information, C & C Lathe Work Management System is installed in Gang Type CNC Lathe to supply and eject the workpieces that cooperate with the CNC Lathe, and to handle the workpieces under the control of the CNC Lathe. It is about.

CNC lathes are the flower of processing mechanical engineering that computer control technology has evolved into the control of machine tools. Behind the spotlight of modern civilization, various machinery are manufactured and moving together, replacing human labor with high efficiency.

Representative examples of the most commonly used automation apparatuses include a gentry type robot and a loader. Horizontal arm type includes arm robot and arm loader. In the gantry type, because the workpiece to be transported is external, the path to the chuck located inside the CNC lathe is longer, resulting in a larger device, which results in a longer loading time and a high price. The horizontal arm also has a workpiece on the outside but a shorter feed distance, making it faster than the gantry type. However, since the horizontal arm occupies the work space in front of the CNC lathe, there is a problem that prevents internal work such as work replacement or tool change. The more fundamental problem is that the part feeder is outside of the CNC lathe, so the door is always opened and closed for the supply of the workpiece.For safety reasons, it takes a lot of time, and the gripper and gripper to feed the workpiece into the CNC lathe. Since a drive structure is required, and a body and a driving device for moving the gripper drive structure are required, such an automation device is large in appearance and complicated, and expensive, but has a disadvantage in that it is slow to supply. This automation device can reduce the manpower but does not reduce the workpiece supply time, so the operation efficiency of the facility is not improved.

CNC lathes control machine tools by reading the values displayed on the drawings by machine designers, automatically and precisely processing workpieces. Another feature of CNC lathes is the automatic selection of machining tools according to the intention of the machine designer to automate various machining operations. The tool magazine broadens the CNC lathe machining process by receiving a command command from the lathe of the CNC lathe, sending the required tool to the tool gripper in response to the command and changing various cutting tools.

CNC lathes work in conjunction with tool magazines to enable a variety of machining options, but tool magazines have been pointed out as an inefficient factor for machining small workpieces. Small workpieces required by various industrial products are typically tubular, rod-shaped or hexagonal rod-shaped workpieces up to 7 cm in length and 5 cm in diameter, accounting for most of the workload generated throughout the cutting industry.

Gang type CNC lathes have emerged as CNC lathes to improve the inefficiency of CNC lathes and to process small workpieces at low cost, and are widely used throughout the cutting processing industry. Gang-type CNC lathes are designed to automatically cut small workpieces by replacing tool magazines that are coupled to CNC lathes with tool bars. Gang type CNC lathes are equipped with a tool table corresponding to the spindle chuck. The tool table is assembled with multiple tools ready for immediate operation, and the CNC lathe control unit controls the tool table when the tool needs to be replaced to disconnect the working tool from the spindle chuck and to contact the other tool with the workpiece. To continue machining the workpiece. One of the tools can also be a gripper. The pneumatic gripper, which is set on the tool post, is connected to the compressed air and the control command of the CNC lathe allows the gripper to be gripped or ungripped. In this way, the gang type CNC lathe is to continue the work by changing the work tool among the tools 1 to 6 already set in the tool table, so that the tool replacement time and copper wire is very short.

The present invention aims to provide a workpiece management system that manages the supply and workpiece ejection of a workpiece by adding an external control command set, a workpiece feeder and a workpiece workpiece exit gate to a gang-type CNC lathe that controls the tool table with internal control. The present invention seeks to provide a workpiece management system in which two workpiece grippers are set on either side of a tool table on a CNC lathe, respectively, as one of the tools. The present invention aims to provide a workpiece management system for simultaneously controlling the grip of a workpiece before being fed from the workpiece feeder and the grip of the workpiece being processed on the spindle chuck with two grippers set on the tool post. The present invention seeks to provide a workpiece management system which delivers workpieces to the spindle chuck while machining them and at the same time delivers the workpiece to the discharge gate. As described above, the present invention aims to provide a workpiece management system that achieves a control economy by increasing the work efficiency of a gang-type CNC lathe by performing twin work management of the workpiece as a workpiece management system coupled to the inside of the CNC lathe. In addition, the invention directly supplies the workpiece before machining through the internal channel of the CNC lathe, thus minimizing the machining invalid time such as opening and closing time of the door and arm in-out time. This is to save work space. The present invention seeks to provide a feeder for feeding a workpiece to a tool post before machining.

Describes a workpiece management system for Gang Type CNC lathes (sometimes abbreviated as "CNC lathes").

In the gang-type CNC lathe 100, the tool post 120 is supported on a two-dimensional plane of the bed 150 that is parallel to the coordinate axis y of the spindle chuck 110. The x, y coordinate system that the control unit of the CNC lathe can access the tool post 120 on the bed 150 is Lx, Ly. Characteristic of the gang type CNC lathe is to move a plurality of tools set on the tool post 120 in the replacement control of the tool in the x, y coordinate system with the tool post to access the selected tool to the workpiece. Likewise, in the numerical control of the cutting operation, the tool post is numerically controlled in the x, y coordinate system to cut the workpiece with the selected tool.

The M code of the CNC lathe is the control command of the auxiliary device that the operator inserts into the control code of the CNC lathe. Auxiliary devices include auxiliary devices attached to the CNC lathe and external devices selected and used by the operator. The operator adds the M code to the control code in order to cooperate with the CNC lathe to install and add an external device to the CNC lathe. CNC lathes are provided with editors for editing M codes. The operator inserts an externally written program into the CNC lathe using the editor or edits the M code using the console key. The M code inserted in the program control reads the status of the external device through the input port, transmits the control signal to the external device through the output port, and drives the driver through the output port to drive the external device with the output of the driver. In order to drive the external device, conditional control is executed based on the signal read from the input port.

The workpiece management system of the CNC lathe has been proposed based on the x, y coordinate system control and the M code control of the CNC lathe controlling the tool post 120 and the tool post controlled by the tool change operation and the cutting operation of the workpiece. The workpiece management system of the CNC lathe receives two workpieces before machining and sets them on the spindle chuck 110 and two grippers 130 and 140 to simultaneously transfer the processed workpiece to the workpiece discharge gate 300. ) Was set together with the tool post, the workpiece feeder 200 and the workpiece discharge gate 300 were installed on the CNC lathe, and M code for the workpiece management was inserted into the CNC lathe control.

Specifically, the workpiece management system of a gang type CNC lathe is a workpiece of one side of the spindle chuck 110 which becomes a constant drainage distance Lx1 of the tool arrangement interval in the plane of movement of the tool parallel to the x, y coordinate system of the tool set as shown in FIG. The workpiece feeder 200 installed on the CNC lathe to supply the workpiece before machining to the feed point 131, the spindle becomes the constant drainage distance Lx2 of the tool array spacing in the plane of travel of the tool, and Lx1 = Lx2. The workpiece discharge gate 300 installed on the CNC lathe to deliver the processed workpiece to the other workpiece discharge point 141 of the chuck, and one of a plurality of tools set on the tool stage 120 on one side of the tool stage. The first work gripper 130 to be set, the second one of the plurality of tools to be set on the tool stand is set on the other side of the tool rest 120, the second gripper installation distance Lx1 Peacock To further control the workpiece to the gripper 140, and the control of the CNC lathe was composed of M, which are inserted into the control of a CNC lathe.

The distance between the workpiece feed point 131 and the workpiece discharge point 141 in the coordinate y axis of the spindle is the same distance Lx1 = Lx2, and the tool arrangement spacing of the tool bar is the same distance. The correspondence between the grippers 130 and 140 and the spindle chuck 110 shows that the distance between the workpiece feed point 131 and the workpiece discharge point 141 in the spindle coordinate axis y is the same distance, and the tool arrangement interval of the tool post is the same distance. When the first gripper 130 reaches the workpiece supply point 131 in the control of the tool post 120, the second gripper 140 moves in front of the spindle chuck 110, and conversely, the first gripper 130. To the center of the spindle chuck 110, the second gripper 140 is guided to the discharge gate 300.

The workpiece management system of the gang type CNC lathe controls the operation of the pneumatic gripper with the M code inserted in the control of the CNC lathe so that the first gripper 130 of the tool post 120 supplies the workpiece before machining from the workpiece feeder 200. At the same time, the second gripper 140 draws out the workpiece processed by the spindle chuck 110, and transfers the workpiece before the machining received from the first gripper 130 to the spindle chuck 110 and simultaneously removes the workpiece. 2 gripper 140 controls to deliver the processed workpiece to the discharge gate (300).

The CNC lathe repeats the workpiece in the work loop and performs M code control when the operator encounters the M code inserted in the control flow.

The CNC lathe 100 processes the workpiece before numerically transmitted to the spindle chuck 110 in the previous control cycle as a numerical control. The machining process controls the spindle chuck to chuck the workpiece, then drives the working spindle, and when the spindle's drive reaches the program speed, two-dimensional control of the tool post 120 is used to select or replace the tool and then the tool post 120 ) Cut the workpiece by two-dimensional numerical control. The selection control of the tool and the cutting control of the workpiece by the selected tool are repeated until the workpiece cutting is completed in response to the program data of numerical control.

Workpiece feeder is a device that is installed in addition to the existing CNC lathe to supply the workpiece to the workpiece transfer point 131 before machining so that the CNC lathe can work quickly and repeatedly the workpiece machining. Workpiece feeders can be manufactured in low-cost jig types or in two-axis or three-axis robots. However, considering the profitability of CNC lathes, low-cost jig-type workpiece feeders can have a practical effect.

The workpiece feeder 200 according to the embodiment is a workpiece feeder that is halfway between a jig type and a robot type, and monitors the workpiece transfer gate to supply the workpiece by itself when the workpiece gate is empty, and the workpiece into the workpiece alignment feeder when no workpiece is supplied to the feeder. It was built to demand supply.

A plurality of pre-processing workpieces (p, pn, pn, pn, ...) installed in the alignment feeder 500 and the V beam 210 and arranged in the same pitch on the V beam in response to the control of the feeder controller. The workpiece feeding mechanism 230 which moves forward by one pitch s1 at the same time to reach the transfer gate 221 of the collector tube 220 to await the grip of the workpiece gripper 130, and Workpiece Detection Sensor (217) If the workpiece is not detected and the workpiece is not detected, the workpiece alignment supply signal is transmitted to the workpiece alignment supply 500. If the workpiece is not detected in the workpiece transfer gate 221, the feeding mechanism 230 is detected until the workpiece is detected. It is composed of a feeder control unit for controlling the repetitive driving.

The feeder 200 control unit 290 of FIG. 20 inserted into the CNC lathe is a control for providing an external sensor signal to control of the CNC lathe and operating an external device as a control of the CNC lathe.

20 is a workpiece detection sensor 217 that is connected to the port io1 and provides a status signal at the M code m1, and is connected to the port o01 to the workpiece at the M code m2. Connection to the workpiece alignment feeder 500 and the port o31 receiving the supply signal is connected to the first gripper 130 and the port o41 receiving the ungrip signal from the M code m3 through the driver 130d.

The first gripper 130 which is grip-controlled by the cord m7 and the port o42 are connected to the first gripper 130 through the driver 140d. And a second gripper 140 under lip control.

Referring to the operation of the control unit 290 of FIG. If there is no detection of the workpiece at the port i01 by inserting the M code m2, the workpiece supply signal is sent to the port o01 that controls the workpiece alignment supply, and the M code m3 is inserted to 1 The signal to ungrip the gripper 130 is sent to the port o31, the M code (m4) is inserted to send the signal to the port o41 to ungrip the second gripper 140 through the driver 140d, , The M code m5 is inserted to receive the state of the workpiece holding sensor 227 at the port i02, and the M code m6 is inserted to the driver 251d if there is no detection of the holding workpiece at the port i05. A control signal for driving the air cylinder 251 of the feeder driver for one reciprocating forward and backward driving to the port o02. The signal is inserted into the port o32 to insert the M code m7 to grip the first gripper 130 through the driver 130d, and the second gripper 140 is inserted by inserting the M code m8. The gripping signal is sent to the port o42 to manage the supply of the workpiece by the feeder 200 in the process of managing the workpiece.

The control unit 293 of the feeder 200 of FIG. 21 independent from the control of the CNC lathe is a control that cooperates with the control of the CNC lathe into which the M code is inserted in order to operate the grips 130 and 140. The control unit 293 of FIG. 21 transfers the workpiece to the workpiece transfer gate 221 when there is no workpiece in the workpiece transfer gate 221 corresponding to the workpiece feed point 131. If there is a workpiece in the workpiece transfer gate 221, the CNC control is in a workpiece standby state to receive the workpiece at the workpiece feed point 131.

The configuration of the microcomputer feeder control unit 293 of FIG. 21 is installed on the programmed control microcomputer 281 and the projection 215 of the V beam and connected to the microcomputer to provide the microcomputer with a workpiece detection signal on the V beam. It is installed in the sensor 217 and the collector tube 220 and is connected to the microcomputer to respond to the control signal c1 of the holding sensor 227 and the microcomputer to provide the microcomputer with the workpiece detection signal of the workpiece transfer gate 221. In response to the control alignment signal c2 and the workpiece alignment feeder 500 for supplying the workpiece to the protrusion 215 of the V beam, the air cylinder 251 is driven forward by the compressed air of the pneumatic source 259 and the control signal c3 is responded to. It includes a solenoid valve 253 for driving the air cylinder 251 backward with the compressed air of the pneumatic source (259).

When the workpiece feeder 200 is installed on the CNC lathe, the workpiece transfer gate 221 is matched to the workpiece feed point 131 of the CNC lathe. When the feeder control unit 293 has an action, the workpiece detection sensor 217 is monitored to transmit the workpiece supply request signal c1 to the workpiece alignment supply 500 when there is no workpiece in the V beam protrusion 215. The workpiece detection sensor 217 is mounted on the V beam to enable workpiece detection as a proximity sensor on the surface of the V beam. The workpiece alignment supply 500 supplies the workpiece to the V beam protrusion 215 through the escalator 510 in response to the signal c1. The feeder control unit 293 monitors the holding sensor 227 and repeatedly drives the feeding mechanism 230 with control signals c2 and c3 until there is no workpiece in the workpiece transfer gate 221 in the collector tube 220. By controlling, a plurality of workpieces are arranged on the V beam, and the workpiece p placed at the foremost position is transferred to the workpiece transfer gate 221. Since the V-beam protrusion 215 becomes empty once the feeding mechanism 230 is driven once, the feeder control unit 293 generates the workpiece supply signal c1 each time.

FIG. 2 illustrates a control example of the CNC lathe in which the M code is inserted so as to cooperate with the control of the control unit 293 of the feeder 200. FIG. The controller of the CNC lathe stops the driving of the spindle when the workpiece is finished and controls the spindle chuck 110 to control the processed workpiece to an ungrip state and to control the tool post 120 to control the first gripper 130. To the front of the workpiece transfer point 131. The control unit of the CNC lathe advances the tool post in the direction of the spindle axis (y), grips the workpiece before machining in the first gripper 130 (M code control), and grips the workpiece processed in the second gripper 140. (M code control). The control unit of the CNC lathe reverses the tool post 120 in the spindle y-axis direction to separate the workpiece before machining from the workpiece supply point 131 that is gripped, and at the same time, separate the workpiece from the spindle chuck 110. The control unit of the CNC lathe controls the tool post 120 to move the workpiece before machining bited by the first gripper 130 in front of the spindle chuck 110, and at the same time, discharges the workpiece that has been cut by the second gripper 140. The transfer is performed in front of the gate 300. The control unit of the CNC lathe advances the tool post 120 in the spindle y-axis direction to transfer the workpiece before the machining carried by the first gripper 130 to the spindle chuck 110 (M code control) and simultaneously the second The gripper 140 delivers the processed workpiece that has been transported to the workpiece discharge gate 300. The control unit of the CNC lathe 100 transfers control to the step for processing the newly supplied workpiece.

The workpiece feeder 200 has the function of a workpiece buffer. In the feeder 200, the workpiece buffer serves to dynamically retain a plurality of workpieces in the process of supplying the workpieces by the V beam supplying the workpieces. The V beam connecting the workpiece transfer gate 221 and the escalator 510 has a length of the V beam divided into a plurality of workpiece pitches s1. Since the feeding mechanism 230 moves the plurality of workpieces forward by moving the pitch s1 section at a time in one cycle of feeding operation, it always has a certain number of workpieces on the V-beam to have the function of a workpiece storage buffer, thus operating the CNC lathe. It is to prevent the rate drop.

The workpiece feeding mechanism 230 is coupled to the linear guide 232 attached to the V beam 210 and the movable body 232 of the linear guide and attached to the carrier 237 on the drive mechanism side to move forward in the feeding stroke s3. And an upper support pin for each of the carrier 237, the pin stopper 235, and the pin stopper 235, which are installed at a pitch s1 interval at which the workpiece of the V beam is disposed on the carrier 237, which performs backward feeding and substantially feeding operation. 236 is assembled to the carrier 237 and is ungripped in the backward movement of the carrier 237 beyond the workpieces (pn, pn, pn) above the V beam 210 and again in the forward movement pin stopper 235 In response to the control signals of the feeding pin 233 and the feeder control unit 290, which are brought into the closed state and simultaneously push the workpieces pn, pn, pn, ... on the V beam 210 to move the pitch s1 section. Feeder drive mechanism for moving the workpiece on the V beam by moving the carrier 237 forward and backward And a position adjusting coupler 260 for assembling the feeder drive mechanism 250 to the V beam 210 by adjusting the position of 250 and the position thereof.

The position adjusting coupler 260 includes a connecting plate 261 attached to the bottom of the V beam, an adjusting hole 262 provided at the front and rear of the connecting plate, a bracket 254 of the feeder driving mechanism 250, and an adjusting hole ( 262, the handle attaching bolt 264 for attaching the bracket 254 to the connecting plate 261 and the positioning scale 265 installed on the bracket and the indicator needle installed on the connecting plate 261 ( 266). When the bolt 264 is loosened, the connecting plate 261 and the bracket 254 flow, and the carrier 237 with the driving mechanism 250 within the length of the adjusting hole 262 with respect to the V beam 210. You can move forward or move backward. The amount of movement of the carrier 237 is shown between the scale 265 and the indicator needle 266. Since the amount of movement of the carrier 237 shown in the indicator needle moves a point of pitch s1 on the V beam 210, the carrier 237 protrudes from the workpiece transfer gate 221 to the workpiece transfer point 131 due to the movement of the carrier 237. The protruding length of the work piece p can be selected. The proper protruding length of the workpiece is about 10 mm. When the workpiece is changed for processing, the carrier 237 is moved to be fixed according to the length of the workpiece.

The feeder drive mechanism 250 is an air cylinder 251 using the compressed air of the CNC lathe as a power source in the embodiment. The stroke distance of the drive piston rod of the air cylinder 251 is matched with the feeding stroke s3. When the piston rod of the air cylinder moves forward, the carrier 237 supported by the movable body 232 of the linear guide advances the feeding stroke s3. On the contrary, when the piston rod moves backward, the carrier 237 reverses the feeding stroke s3. do.

The feeding clock s3 of the carrier 237 is a distance obtained by adding the return stroke s2 of the feeding pin 233 to the arrangement pitch s1 of the workpiece. The relation between the feeding stroke s3 and the pitch s1 is expressed as s3 = s1 + s2. The effective working distance at which the carrier 237 feeds the workpiece in the feeding stroke s3 is the pitch s1 and the return stroke s2 is not utilized for the workpiece conveyance. The return stroke s2 of the feeding pin 233 is the distance that the feeding pin 233 can ride on the workpiece having the largest diameter.

The feeder drive mechanism 250 under the control of the feeder control unit 290 advances the carrier 237 to the feeding stroke s3 in one cycle of the reciprocating drive operation, and then reverses the feeding stroke s3 to return to the starting position to drive the next cycle. Wait. The feeding operation of the carrier 237 is to move the plurality of workpieces (pn, pn, pn, ...) on the V beam 210 pitch s1 section by moving the plurality of feeding pins 233 forward and backward at the same time.

In the forward operation of the feeding stroke s3, the feeding pin 233 advances the return stroke s2 of the feeding pin with no load while being closed by the pin stopper 235, and the remaining pitch s1 is followed by the feeding pin 233 behind the workpiece. It is a load drive that touches and pushes a workpiece. On the contrary, in the reversing operation of the feeding stroke s3, the feeding pin 233 touches the front of the workpiece, and the feeding pin 233 opens and moves backwards over the workpiece, and the end of the feeding pin 233 passes through the return stroke s2 of the feeding pin. It is returned to its own weight beyond the end of the workpiece. This completes the return operation of the feeding pin. A return spring may be installed on the feeding pin 233 to ensure the return operation of the feeding pin 233. Torsion springs are recommended as return springs for the feeding pins.

One side of the V-beam is assembled with a support pin 212 on the CNC lathe and the front is assembled with the height adjusting means 270. V-beams are manufactured with a slider structure that corresponds to the contour of the workpiece before machining. The outer surface of the workpiece before machining is usually the circumferential surface or the major surface of the hexagonal bar. In order to accommodate the workpiece having the hexagonal rod main surface in the same position to the V-beam, the groove 211 of the V-beam is made of an inclined surface 213 corresponding to the main surface of the hexagonal bar. The V beam 210 is made of aluminum die casting or made of aluminum extrusion. In order to manufacture the V beam of aluminum, the slider 214 may be attached to the inclined surface 213 by using a stainless steel sheet to manufacture the V beam.

The size of the workpiece before machining is generally 10-40 mm in diameter and in the range of 30-70 mm in length. V-beam 210 is manufactured to a standard that can process all of the workpieces in this category. When the workpiece is placed in the groove 211 of the V beam 210, the center of the workpiece is raised or lowered depending on the diameter of the workpiece. In order to align the center of the workpiece mounted on the inclined surface of the V beam with the center of the first gripper 130, the height of the front of the V beam must be changed according to the diameter of the workpiece. According to this requirement, the workpiece feeder further includes a height adjusting means 270 for adjusting the center of the workpiece before processing to the grip center of the first gripper 130 and a workpiece supporting means 240 for holding the workpiece before delivery.

The front height adjusting means 270 of the V beam 210 is attached to the end of the V beam, a horseshoe-shaped longitudinal guide groove 271 which is disposed on the left and right sides of the workpiece transfer gate 221 on the front plate 223 of the collector tube. The slider wing 272 inserted into the vertical guide groove 271 so that the left and right wings move up and down, the slider wing is covered on the right and left of the workpiece transmission gate, and the slider wing is closed by tightening the bolt 274. A screw hole (273) fixed to the platen, a lifting screw hole (275) installed at the bottom of the V beam, and a hole (277) in the collector tube to insert a tool to raise or lower the height of the V beam. 275) was composed of a lifting screw 276 inserted.

In order to adjust the height of the V beam, first, the fixing bolt 274 is loosened, and the workpiece is shifted to the center of the workpiece transfer gate 221 after the workpiece is biased up or down the transfer gate 221. Tighten the fixed by adjusting the height of the V-beam in the process of being fixed between the front plate 223 and the pressure plate (273) by fixing the rider wing 272. When the height adjusting means 270 is operated in the height adjustment process of the V beam, the bolt 274 is released to freely move the slider wing 272 up and down and the lifting screw 276 is moved from the hole 277 to the tool. When rotating in one direction, the lifting screw 267 is moved outwardly from the hole 275, and in response to this, the front end of the V beam is moved upward along the longitudinal guide groove 271, and conversely, the screw 276 is moved. When rotating in the other direction, the lifting screw 267 is moved inwardly from the hole 275, and in response thereto, the front end of the V beam moves downward along the vertical guide groove 271, thereby adjusting the front height of the V beam. It will be. When the bolt 274 is filled in the state in which the front height of the V beam is adjusted, the slider wing 272 is fixed to the collector tube in the guide groove 271 between the front plate 223 and the pressure plate 273.

If the minimum diameter of the workpiece is 10 mm and the maximum diameter of the workpiece is 40 mm, then the height adjustment of the V beam by the height adjustment mechanism is usually 15 mm.

The work support means 240 is assembled to the bracket 241 in the collector tube 220 by the support pins 246 with the support pins 246 and supported by the stopper 248 to be in a vertical posture before the operation. When the p) enters the workpiece transfer gate 221, the support clip 245, which is inclined to be inclined to move the workpiece and the tip is placed on the workpiece, and the end of the support clip 245 presses the workpiece with a spring elasticity. It consisted of the pressure spring 247 installed. In the figure the pressure spring is referred to as a torsion spring.

When the workpiece (p) loaded on the V-beam enters the workpiece transfer gate (221) by the drive of the feeder drive mechanism 250, the support clip 245 is inclined and the tip reaches the workpiece (p) and the pressure of the spring (247). Press the workpiece (p). The workpiece is pressed at the end of the support clip to deliver the workpiece safely to the first gripper 130, and when the first gripper 130 pulls out the workpiece, the support clip 245 is stopped by the pressure of the spring 247. It is restored to the posture before departure until it reaches 241) and waits until the next workpiece is supplied.

Holding sensor 227 is a sensor for detecting the workpiece of the workpiece transfer gate 221. Since the distance between the holding sensor 227 and the workpiece varies with the diameter change of the workpiece, the detection of the workpiece by the holding sensor may be unstable. The workpiece holding sensor of FIG. 6 embodiment is a proximity sensor. The holding sensor 227 is installed close to the work support clip 245 so that the work support clip 245 detects the work support clip 245 in proximity to the holding sensor 227 in the first position where the stopper 248b touches. It is programmed to be used as a signal of no work and when the support clip 245 is separated from the stopper 248b, it detects the separation state of the work support clip 245 and is programmed to use it as a work present signal. It can overcome the diameter difference and perform stable workpiece detection.

The grippers 130 and 140, which are set on the tool bar of the CNC lathe, move in the two-dimensional plane of the bed under the control of the CNC lathe to access the workpiece, the spindle chuck or the workpiece discharge gate, and the compressed air to the control command. The gripper (130, 140) is opened and closed to drive the painting or ungrip the workpiece.

The collector tube 220 is assembled to the CNC lathe with the flange 224, and at the time of assembly, the workpiece transfer gate 221 is aligned with the workpiece transfer point 131 of the CNC lathe, so that the setting of the V beam is adjusted by adjusting the height of the V beam. When the center of the workpiece is aligned with the workpiece transfer gate 221, the workpiece is accurately transferred to the workpiece transfer point.

The workpiece discharge gate 300 is a guide hole of a gate hopper type installed on a CNC lathe so that the second gripper 140 can approach and transfer the workpiece. It consists of a workpiece workpiece delivery guide 310 for safe delivery of the workpiece put into the workpiece discharge gate and a container 320 ready to collect and collect the workpiece. When the workpiece processed in the second gripper 140 is transferred to the gate 300, the workpiece moves in the guide 310 and is collected in the collection container 320. Since the collection container is a collection container, a plurality of collection containers are prepared. Once the container is filled, collect the container and assemble the empty container.

In Fig. 22, a jig-type workpiece feeder is cited. Jig-type workpiece feeder needs to change the nozzle assembled in the coupler to the nozzle suitable for the workpiece diameter in order to supply the workpiece (p) of different diameter to the CNC lathe. You have to change it.

Specifically, the jig-type workpiece feeder 400 is supported by the CNC lathe 100 to transfer the workpiece p, which is supplied to the nozzle 423, to the workpiece transfer point 131 and in front of the workpiece transfer pipe 410. Coupling tube 420 to be connected to the nozzle, passages 101 and 102 installed on the CNC lathe, the front is assembled to the coupling tube 420, the workpiece transport pipe 410 to receive the workpiece (p) from the back , Projected to the outside of the CNC lathe is provided on the projection 431, the projection 431 of the feed pipe to receive the workpiece (p) from the outside, the workpiece escalator of the workpiece alignment feeder 500 or the workpiece feeder (530) ( In the groove 541 of the 540, the workpiece loading chamber 434, which receives the workpiece (...), is connected to the flange 433 at the rear of the protrusion 431 and pushes the workpiece to the pushing rod 432. Including the air cylinder 430 and the drive control unit 495 of the workpiece feeder It became a composition. The workpiece feeder 530 may include a workpiece alignment guide 570. The workpiece alignment guide 570 is made in the form of a trough 571 for aligning the workpieces in parallel and loading them, and transferring the workpieces in free fall using a tilt. The workpiece alignment trough 571 may load the workpiece by hand and thermally zigzag to increase the loading amount of the workpiece.

The workpiece supplied in the transverse row from the groove 541 of the escalator 540 of the workpiece alignment feeder enters the loading chamber 434 at the end workpiece transfer portion 542 of the groove 541. When the pushing rod 432 of the air cylinder 430 is advanced, the workpiece in the loading chamber 434 is pushed by the feed path 411 of the feed pipe 410 to be moved. When the pushing rod 432 of the air cylinder 430 moves backward, the workpiece placed on the transfer path 411 remains intact and the loading chamber 434 is emptied. At this time, one workpiece in the standby state in a horizontal row on the workpiece escalator 540 is loaded in the loading chamber 434. When the pushing rod 432 of the air cylinder 430 performs a single reciprocating operation of forward and backward, the second workpiece is arranged in series behind the first workpiece and the front workpiece is transferred to the feed pipe 411. 1 pitch shift, which is 1 workpiece length at. When the workpiece pushing operation of the air cylinder is repeated, the feed path 411 of the feed pipe is filled with the workpieces arranged in series, and the workpiece in front is placed on the workpiece transfer gate 422 of the nozzle 423, so that the CNC tool The first gripper mounted on the stand can grip the workpiece at the workpiece transfer point 131.

For the workpiece arranged in series in the feed path 411 of the feed pipe 410, each time the air cylinder 430 is driven once, one pitch s4, which is the length of the workpiece, is always moved regardless of the length of the workpiece. The drive stroke s6 of the pushing rod 432 of the air cylinder 430 is matched to the length of the maximum workpiece. In this situation, if the length of the workpiece projecting to the workpiece transfer point 131 of the nozzle 423 is adjusted to the optimum protrusion length of 10 mm, the length of the feed pipe 410 is adjusted to supply the longest workpiece. The flange 430 for assembling the 430 to the transfer pipe 410 should be made to be variable in length.

The simplest variable length flange fits a washer 437 of different thickness on the face where the flange 433 and the air cylinder 430 abut. Since the difference between the length of the minimum workpiece and the maximum workpiece is 40 mm = 70 mm-30 mm, the maximum adjustment length of the flange 433, which is adjusted using the washer 437, is 40 mm. In this way, the flange connecting the air cylinder 430 to the protrusion 431 of the workpiece conveying pipe 410 has a maximum washer of 40 mm to adjust the length of the workpiece projecting from the end of the nozzle when the length of the workpiece is changed. It is a flange to be fitted.

Coupling tube 420 is a flange 421 for assembling the tube on the CNC lathe, a plurality of nozzles 423 corresponding to the diameter of the workpiece (p) to replace the cylinder 427 and the workpiece transfer for assembly The feed pipe insertion hole 428 for connecting the pipe to the rear of the nozzle was configured.

Since the diameter of the workpiece supplied from the workpiece feeder 400 is 10 to 40 mm and the length of the workpiece is 30 to 70 mm, a plurality of workpiece transfer pipes 410 and nozzles 420 corresponding to the length and diameter of the workpiece are manufactured. When starting the CNC lathe work is to replace the nozzle assembled in the cylinder 428 and to replace the transfer pipe assembled in the insertion hole (428).

The nozzle 423, which is assembled to the coupling tube 420, transfers the supplied workpiece from the workpiece transfer gate 422 and the transfer pipe 410 to support the workpiece p to the workpiece transfer point 131. An expanded inlet 425 into which the workpiece is introduced, and an inclined guide surface 426 between the inlet 425 and the smaller diameter workpiece transfer gate are manufactured.

The workpieces p and pn which are pushed by the pushing rod 432 of the air cylinder and are moved in a serial arrangement state pass through the inlet 425 and the inclined surface 426 of the nozzle in the conveying path 411 of the conveying pipe. 422). The tolerance of the workpiece transfer point accommodated by the first gripper 130 installed on the tool post of the CNC lathe is within 3 mm. Since the grip arm of the gripper wide open attempts to transfer the workpiece to accommodate the position error of the workpiece transfer point (131). Since the diameter of the workpiece supplied from the workpiece feeder 400 is 10 mm to 40 mm, the size of the feed path diameter d1 of the workpiece feed pipe 410 and the workpiece transfer gate diameter d2 of the nozzle 420 are 16 mm in diameter. , A plurality of nozzles 420 and the workpiece transfer pipe 410 corresponding to 24mm, 30mm, 36mm, 42mm should be manufactured and the transfer pipes and nozzles selected according to the work should be selected.

The workpiece escalator 540 connected to the inlet of the workpiece loading chamber 434 of the protrusion 431 freely drops the grooves 541 to which the workpieces are mounted in parallel and are sequentially supplied and the workpieces to be mounted in the grooves. The workpiece delivery part 542 which supplies to the inlet of the furnace loading chamber 434 is included.

Workpieces (...) that are aligned in parallel and move downward inclined surfaces along the grooves 541 free fall from the workpiece transfer part 542 when the pushing rod 432 moves backward and the loading chamber 434 is empty. The workpiece is transferred to the workpiece loading chamber 434.

The workpiece loading chamber 434, which is installed in the protrusion and receives the workpiece from the workpiece supply guide, is a workpiece escalator 540 when the pushing rod 432 of the air cylinder 430 pushes the workpiece pn and returns to the original position. The workpiece (...) to be delivered in the free fall drop to match the entrance of the loading chamber to the workpiece delivery unit 542 to be seated in front of the pushing rod 432.

The workpiece loading chamber 434, whose inlet is connected to the workpiece transfer part 542, is aligned in parallel when the pushing rod 432 moves backward and the loading chamber 434 is empty, and is downward along the groove 541. The workpiece (...) moving the inclined surface is to be delivered to the free fall in the workpiece transfer unit 542.

The air cylinder 430 installed behind the feed pipe protrusion 433 to the flange 430 to push the workpiece (...) in series moves forward and backward of the stroke (s6) to push the workpiece and load the loading chamber ( Push rod 432 to empty the 434, pitch adjusting washer (437) is inserted between the flange 433 and the air cylinder 430 to move the work of the loading chamber 434 pitch (s4) Was done.

The air cylinder 430 moves the workpieces pn and p arranged in series when the pushing rod 432 is moved in the transfer path 411 of the transfer pipe 410 to nozzle the previous workpiece p. The workpiece transfer from the workpiece transfer gate 422 to the workpiece transfer point 131. The length of the workpiece projecting to the workpiece transfer point 131 is to adjust the length by adjusting the thickness of the washer 437 and to make the pitch s4 of the workpiece by the stroke s6 operation of the pushing rod 432.

The second gripper 140 is controlled.

When the CNC lathe meets the M code m11 in control, the control signal of the driver 130d is sent to the port o31 to ungrip the first gripper 130. When the M code m12 is met, the control signal of the driver 140d is sent to the port o41 to ungrip the second gripper 140. When the M code m13 is met, the control signal of the driver 437 is sent to the port o12 to control the air cylinder 430 to reciprocally drive. When the M code m16 is met, the control signal of the driver 130d is sent to the port o32 to grip the first gripper 130. When the M code m17 is met, the control signal of the driver 140d is sent to the port o42 to grip control the second gripper 140.

In this way, the workpiece management system of the CNC lathe is a control process in which the first gripper of the tool bar receives the workpiece before machining from the workpiece feeder and simultaneously the second gripper pulls out the machined workpiece from the spindle chuck. It is a twin operation process that delivers the workpiece to the spindle chuck and at the same time transfers the workpiece processed by the second gripper to the discharge gate, and manages the workpiece with high efficiency.The gripper is a M code that is inserted into the CNC lathe.
