Description

  The present invention relates to a joint piece manufacturing apparatus for manufacturing a joint piece constituting a bending portion provided in an insertion portion of an endoscope.

  2. Description of the Related Art In recent years, endoscopes have been widely used in which an elongated insertion portion is inserted into a body cavity or a duct so that a subject image in the body cavity or the duct can be displayed on, for example, a monitor for observation. The insertion portion of an endoscope is generally configured by connecting a distal end portion, a bending portion, and a flexible tube portion in order from the distal end side. The tip is formed of a hard member. The bending portion is configured to be able to bend in the vertical and horizontal directions, for example, by connecting a plurality of joint pieces so as to be rotatable. The flexible tube portion is configured by arranging a flex tube, a mesh tube, and an outer skin in order from the inside so as to have a desired flexibility.

  For example, Japanese Patent No. 1866174 discloses a method for manufacturing a node ring of an endoscope bending tube. The joint piece constituting the bending portion shown in this publication is processed by, for example, a laser device disposed in the processing unit as shown in FIG. Specifically, the outer surface of a thin-walled short tube (hereinafter also referred to as a pipe member) 201 is irradiated with laser light from a laser oscillator 202 to form a joint piece 201a having a desired shape. At that time, the pipe member 201 needs to be rotated and moved forward and backward with respect to the longitudinal direction of the pipe member. Therefore, the pipe member 201 is gripped by the chuck 204 of the rotating jig 203 that is integrally fixed to a table (not shown) that is movable in the longitudinal direction of the pipe member. The rotary jig 203 includes a rotary table 206, and a chuck 204 and a speed reducer 205 are integrally provided on the rotary table 206. Then, the power of the motor 207 is transmitted to the speed reducer 205 via the belt 208, whereby the chuck 204 integrated with the rotary table 206 is rotated and the pipe member 201 is rotated.

Therefore, when processing the joint piece 201a by irradiating the pipe member 201 with a laser beam, the forward / backward movement of the table to which the rotary jig 203 is fixed in the longitudinal direction of the pipe member, and the rotation of the rotary table 206, Are controlled synchronously. As a result, for example, as shown in FIG. 15, a joint piece 201 a having a desired shape having a convex portion 211 and a through hole 212 is formed from the pipe member 201.
Japanese Patent No. 1866174

  However, in the method for manufacturing a bent tube for an endoscope bending tube disclosed in Japanese Patent No. 1866174, the rotation of the rotating jig is rotated by transmitting the power of the motor to the rotating jig via a belt. It was. For this reason, when performing nodal ring machining control that synchronizes the advance and retreat movement of the table and the rotation of the rotating jig to perform through hole machining or curved surface convexity machining, the belt during the acceleration / deceleration of the motor that rotates the belt In some cases, the chuck has a delay in rotation due to the bending of the workpiece, resulting in a defect in the machining shape. For this reason, priority is given to synchronizing the forward / backward movement of the table that is directly moved by the motor and the rotation of the rotating jig that is rotated via the belt, that is, priority is given to processing accuracy over processing speed, The joint piece was processed.

  In addition, in order to eliminate problems caused by the bending of the belt, even when the tension of the belt is set firmly, the rotation of the chuck is delayed due to the back crash in the pulley or the speed reducer at the belt connecting portion.

  The present invention has been made in view of the above circumstances, and provides a joint piece manufacturing apparatus capable of preventing a rotation delay generated in a rotating jig rotated by a motor and improving not only processing accuracy but also processing time. The purpose is to provide.

The joint piece manufacturing apparatus of the present invention holds a pipe member supplied by the joint piece processing pipe member supply unit for supplying the pipe member, and the pipe member supplied by the joint piece processing pipe member supply unit, and holds the pipe member. Then, the pipe member is rotated and moved forward and backward in the pipe supply direction, and the outer surface of the pipe member being rotated and advanced and retracted is irradiated with laser light to process / cut the joint piece of a predetermined shape and a predetermined size. A joint piece manufacturing apparatus comprising:
A rotary shaft unit that is provided in the joint piece processing unit and that grips a pipe member and rotates the gripped pipe member includes a chuck mechanism unit having a chuck body including a pipe member gripping unit that grips the pipe member, and the chuck In a configuration comprising a pipe member rotation motor section that rotates a pipe member gripped by a pipe member gripping section of the mechanism section,
The pipe member rotating motor unit includes a stator and a rotor on which a rotating shaft rotor having a central through hole through which the pipe member supplied by the joint piece processing pipe member supply unit is inserted is coaxially fixed. A motor unit configured as described above, and a chuck mechanism unit configured to include a chuck main body fixed to the rotary shaft rotor and a plurality of chuck claws provided with a central through hole through which the pipe member is inserted, a rotation center of the center axis and front liver over data portion of the chucking mechanism are arranged on the same axis.

  According to this configuration, the rotation driving force of the pipe member rotating motor unit is directly transmitted to the chuck mechanism unit, so that the chuck mechanism unit can be rotated.

Further, since the chuck body rotates simultaneously with the rotation of the rotor, the pipe member gripped by the pipe member gripping portion provided on the chuck body can be rotated with the rotation of the rotor . In addition, the pipe member gripped by the chuck mechanism can be rotated at high speed. As a result, the processing / cutting speed by the laser beam can be greatly improved, and a highly accurate joint piece can be processed.

  According to the present invention, since the pipe member gripped by the pipe member gripping portion of the chuck body is rotated simultaneously with the rotation of the rotor, the rotation delay generated in the rotating jig rotated by the motor is prevented, It is possible to provide a joint piece manufacturing apparatus capable of reducing machining time as well as improving machining accuracy.

And are provided. The core adjustment chuck unit 72 is provided with a pair of position adjustment chuck members (hereinafter abbreviated as adjustment chucks) 75. The interval between the adjustment chucks 75 is a width dimension through which the pipe member 10 supplied by the material supply unit 2 passes without colliding. The adjustment chuck 75 arranged with the pipe member 10 interposed therebetween is operated based on a control signal from the control device, and specifically, is gripped by a closing operation by a drive mechanism unit (not shown).

  As shown in FIGS. 1, 4, and 7 to 9, the chamber 44 is a so-called case body that forms a second internal space 80, which is another space portion, in the first internal space 46. The chamber 44 is formed with a broken material discharge opening 81, a rotary shaft unit side opening 82, a pipe member protruding opening 83, a laser oscillator insertion / extraction opening 84, and a suction opening 85. The rotary shaft unit side opening 82 and the pipe member protruding opening 83 are formed substantially coaxially.

  A broken material recovery box 86 is disposed immediately below the broken material discharge opening 81. The chuck mechanism 52 of the rotary shaft unit 41 is inserted into and removed from the rotary shaft unit side opening 82 based on a control signal from the control device.

A dust collection pipe 87 connected to a second duct 7 a extending from the second dust collector 7 is connected to the suction opening 85. The suction opening 85 is provided with a mesh-like cover member 88 that prevents a relatively large broken material from entering the dust collecting pipe 87.

  Therefore, by setting the second dust collector 7 to the suction state, a part of the dross that is melted by the laser processing and scattered from the outer peripheral surface of the pipe member 10 to the periphery is the suction opening 85, the dust collection pipe 87, the second duct. It is sucked through 7a.

  Reference numeral 89 is an air blow. The air blow 89 blows out air for preventing broken material formed when the pipe member 10 is processed / cut into the gap between the pipe member 10 and the unloader pipe 101. The blowing direction of the air blow 89 is adjusted to the position where the operator stands, so that the broken material is blown off toward the wall side where the door 45a is provided and the opening is not formed.

Next, the discharge unit 4 will be described with reference to FIGS. 1 and 10 to 12.
In the discharge unit 4, the joint piece formed by processing / cutting by the processing unit 3 is moved to the storage box and stored.

  As shown in the figure, the discharge unit 4 is mainly composed of an unloader unit 91, a take-out unit 92, and a collection unit 93. The unloader unit 91, the take-out unit 92, and the recovery unit 93 are disposed in the discharge unit exterior portion 94.

  In the discharge unit exterior portion 94, in addition to the discharge unit 4, a suction hole dross removal unit (hereinafter abbreviated as first dross unit) 95a and a through-hole inner surface dross excision unit (hereinafter referred to as the first dross unit) constituting the dross removal unit 5 95b (abbreviated as second dross unit).

  The unloader unit 91 is attached to and detached from the slide table 96, the unloader main body 97, the rotation holding part 98, for example, four unloader pipe attaching members (hereinafter abbreviated as attaching members) 99, and the collet chuck 100 as an attaching / detaching part. The unloader pipe 101 is mainly configured. An unloader pipe 101 corresponding to the diameter of the pipe member 10 to be processed is attached to the attachment member 99 in advance.

  The unloader body 97 is slidably disposed in the X-axis direction on the slide table 96, and is moved forward and backward in the X-axis direction by a drive mechanism (not shown). In the initial state, the unloader main body 97 is disposed, for example, at the joint piece removal position indicated by a two-dot chain line in FIG. 10, and from the joint piece removal position to the joint piece machining position and in the opposite direction based on the control signal from the control device. Move to.

  The rotation holding unit 98 is fixed to the unloader body 97. The rotation holding unit 98 is provided with a rotation table (not shown), and mounting members 99 are fixed to the rotation table at equal intervals. In the present embodiment, the rotation table of the rotation holding unit 98 is configured to be rotated by 90 degrees. Therefore, in a state where the rotation of the turntable is stopped based on the control signal from the control device, the predetermined mounting member 99 is in a state parallel to the Z axis or a state parallel to the X axis.

  The unloader pipe 101 is attached to the attachment member 99 via the collet chuck 100. In the unloader pipe 101, a suction hole 101a having a predetermined diameter is formed at a predetermined position on the outer peripheral surface. The suction hole 101a is a communication hole that communicates with the through-hole of the unloader pipe 101, and is formed so as to be positioned in the optical path of the laser light, and sucks dross generated during laser processing.

The unloader pipe 101 constitutes a pipe line for sucking a melt, generally called dross, which is generated during processing of the pipe member 10 by the laser light, while preventing transmission of the laser light. Therefore, the unloader pipe 101 is made of, for example, phosphorous deoxidized copper, which has high reflectivity and is difficult to perforate in order to prevent laser light from passing therethrough.
A dross suction hose (not shown) connected to the first duct 6 a extending from the first dust collector 6 is connected to the rear portion of the attachment member 99.

  The unloader pipe 101 is disposed in the through hole of the pipe member 10. For this reason, the diameter dimension of the unloader pipe 101 is smaller than the inner diameter dimension of the through hole. In the present embodiment, the unloader pipe 101 has, for example, four types having different diameters corresponding to the diameter of the pipe member 10.

  As shown in FIG. 11, the unloader pipe 101 having a dross suction hole (hereinafter abbreviated as a suction hole) 101a is formed in the through hole of the pipe member 10 when the pipe member 10 is irradiated with laser light to form a joint piece. Are arranged at predetermined positions. When the unloader pipe 101 is irradiated with laser light from the laser oscillator 65 toward the outer surface of the pipe member 10, the unloader pipe 101 prevents the laser light from reaching the outer surface on the side facing the irradiated surface of the pipe member 10. At the same time, the dross melted by the laser beam and scattered from the pipe member 10 is sucked.

  Specifically, the laser light emitted from the laser oscillator 65 toward the pipe member 10 first penetrates the outer surface of the pipe member 10. Thereafter, the laser light passes through the suction hole 101a, reaches the inner peripheral surface of the unloader pipe 101, and is reflected by this inner peripheral surface. This prevents the laser light emitted from one direction side of the pipe member 10 from passing through the unloader pipe 101 and reaching the outer surface on the other direction side of the pipe member.

  Further, when the laser light emitted from the laser oscillator 65 reaches the pipe member 10, the pipe member 10 is melted. In this state, the pipe member 10 can be processed and cut by removing the melt. For this reason, when irradiating a laser beam, while assist gas is sprayed on a laser beam irradiation surface so that a molten material may be removed, the 1st dust collector 6 is made into the suction state. As a result, a part of the dross scattered by the assist gas falls to the through hole side of the pipe member 10, and the suction hole 101 a disposed almost directly below the laser irradiation surface, the through hole of the mounting member 99, Suction is performed through a dross suction hose connected to the first duct 6a.

  The take-out unit 92 includes a joint piece collection hand (hereinafter abbreviated as a hand) 111, a hand vertical movement mechanism unit 112, a hand turning mechanism unit 113, and a joint piece drop port (hereinafter abbreviated as a drop port) 114. It is mainly composed of. Reference numeral 115 denotes a support column. The support column 115 is provided with a hand up / down moving mechanism 112 and a drop port 114.

  The hand 111 is moved up and down by a hand up-and-down movement mechanism unit 112 constituted by, for example, an air cylinder, and is turned by a hand turning mechanism unit 113 constituted by an air cylinder and a rotary actuator, for example. The hand 111 is provided with an opening / closing mechanism (not shown) that appropriately switches between a hand open state (hereinafter abbreviated as an open state) and a hand closed state (hereinafter abbreviated as a closed state). Based on the control signal from the control device, the opening / closing mechanism unit of the hand 111 is operated to switch the opening / closing state. When the mounting member 99 is in the state where the joint piece is taken out, the joint piece can be gripped by closing the hand 111 with respect to the joint piece which is loosely arranged in the unloader pipe 101. It has become. On the other hand, when the hand 111 is operated from the closed state to the open state by operating the opening / closing mechanism, for example, the joint piece held by the hand 111 can be dropped. Note that the hand 111 can be switched between a large-diameter hand corresponding to a joint piece having a large diameter and a small-diameter hand corresponding to a joint piece having a small diameter according to the difference in diameter of the joint piece.

  As shown in FIG. 12, the recovery unit 93 mainly includes an upper conveyor 121, a lower conveyor 122, a storage box elevator 123, and a storage box pusher 124. The upper conveyor 121 and the lower conveyor 122 are provided with belts 125a and 125b and motors 126a and 126b for moving the belts 125a and 125b by a predetermined amount, respectively.

  For example, seven storage boxes 127 are installed on the belts 125a and 125b. An opening portion of the storage box 127 is arranged immediately below the collection port 128.

  The storage box elevator 123 moves up and down between the belt 125b of the lower conveyor 122 and the belt 125a of the upper conveyor 121 to move the empty storage box 127 placed on the lower conveyor 122 to the upper stage side. The storage box pusher 124 arranges an empty storage box 127 moved from the lower conveyor 122 to a position adjacent to the upper conveyor 121 by the storage box elevator 123 immediately below the collection port 128.

Next, the dross removing unit 5 will be described.
The first dross unit 95a constituting the dross removing unit 5 shown in FIGS. 10 and 13 removes the dross that is fixed to the edge of the suction hole 101a of the unloader pipe 101.

  The first dross unit 95a includes a tip holding mechanism portion 130 that holds the tip portion of the unloader pipe 101, and a dross removal mechanism portion 140 that removes the dross fixed to the suction hole 101a.

  The tip holding mechanism part 130 includes a tip holding member 132 having an abutment surface 131, a sliding block 133 on which the tip holding member 132 is disposed, a holding sliding table 134, and a sliding block 133 in the Y-axis direction. And a holding mechanism air cylinder 135 that moves forward and backward.

The contact surface 131 is provided with contact portions 131 a, 131 b, 131 c, 131 d corresponding to the difference in diameter of the unloader pipe 101 in a stepwise manner. A sliding block 133 is slidably disposed on the holding sliding table 134. As a result, when the sliding block 133 slides and moves, the movement of the tip holding member 132 in the Y-axis direction is prevented.

  It should be noted that the four types of unloader pipes 101 and the tip holding member 132 are arranged so as to be surely disposed in the corresponding contact portions 131a, 131b, 131c, and 131d provided on the contact surface 131 of the tip holding member 132. An arrangement position adjusting unit (not shown) for adjusting the position is provided at the connecting and fixing unit with the sliding block 133. The arrangement position adjusting unit is an urging member (not shown) that adjusts the position of the tip holding member 132 with the urging force when the sliding block 133 is moved to the unloader pipe 101 side, for example.

  Therefore, when the unloader pipe 101 having the largest diameter is disposed on the attachment member 99, the contact portion 131a provided on the most distal side contacts the side surface of the tip portion, and the unloader pipe 101 having a small diameter is disposed. If it is, the contact portion 131d contacts the side surface of the tip portion.

  The tip constituting portion 142 provided with the punch portion 141 is inserted into the suction hole 101a in a state in which the side surface of the tip portion of the unloader pipe 101 is held by any of the contact portions 131a, 131b, 131c, and 131d of the contact surface 131. Moved towards.

  When the leading end component 142 is moved to the unloader pipe 101 side most by the air cylinder 143 for removal mechanism, the leading end of the punch portion 141 is substantially at the center position of the suction hole 101a provided in the unloader pipe 101. Placed in. As a result, the dross fixed to the edge portion is destroyed and removed by the punch portion 141.

  Reference numeral 144 denotes a removal mechanism fixing frame fixed to the support column 115, and a removal mechanism air cylinder 143 is fixed thereto.

  A second dross unit 95b constituting the dross removing unit 5 shown in FIG.

  The second dross unit 95b is configured as a multi-axis drill 151, for example, two types of drills 152 are arranged. The second dross unit 95b is configured to be moved back and forth in the X-axis direction by a drill advance / retreat mechanism 153. The drill 152 has a diameter corresponding to the diameter of the through hole of the unloader pipe 101, and is exchanged based on a control signal from the control device.

  The drill 152 is disposed in the through hole of the unloader pipe 101 in a rotating state. Accordingly, the dross sucked into the through hole through the suction hole 101a and fixed to the inner surface of the through hole is cut off by the rotating drill 152.

  The control device outputs a control signal as described above, for example, to control the operation of the feeding motor 25, the grip control of the chuck mechanism unit 52, the rotation control of the motor unit 54, and the operation control of the X-axis control motor 63.

  A movement position detection sensor 105 for detecting the movement position of the unloader body 97 is installed at a predetermined position of the sliding table 96. The movement position detection sensor 105 reads whether or not the unloader pipe 101 located on the processing unit 3 side does not collide with the processing unit exterior member 45 during a pipe member pulling operation described later. The drop port 114 and the recovery port 128 are connected by, for example, a transparent resin pipe member 129. Therefore, the joint piece dropped to the drop port 114 falls into the storage box 127 through the resin pipe member 129 and the collection port 128. The collection port 128 is provided with a passage sensor (not shown) that counts the number of joint pieces falling into the storage box 127.

The operation of the joint piece manufacturing apparatus 1 configured as described above will be described.
The setup work before the start of the continuous operation (automatic operation) process will be described.

  First, the main power supply of the joint piece manufacturing apparatus 1 is turned on. Next, when starting the continuous production of the desired joint piece, the necessary items such as the item to be processed, the number of processing, the processing date, etc. are input, and the NC program corresponding to the pre-registered processing item is centrally managed by the PC After performing processing for transmission to the operation panel 20, the operation panel 20 provided in the joint piece manufacturing apparatus 1 is turned on. Then, the item, the number of processing, various conditions, the NC program, etc., which are information transmitted from the PC to the operation panel 20 are automatically read. Moreover, the 1st dust collector 6 and the 2nd dust collector 7 are switched to an operation state, and dust collection is started.

  Next, the operator operates a machining position movement command button (not shown) provided on the operation panel 20. Then, the unloader main body 97, the abutting portion 73 of the stopper unit 71, the X-axis moving table 53 on which the rotating shaft unit 41 is placed, the Y-axis direction moving mechanism portion 66, the Z-axis direction moving mechanism portion 67, the feed elevator. The peripheral device such as the above moves to the machining start position, and the preparation on the device side is completed.

  Finally, the worker arranges the pipe member 10 having a predetermined diameter dimension in which a jig is mounted in the V-shaped groove of the stocker 21 of the supply unit 2. Further, up to seven empty storage boxes 127 are set on the belt 125b of the lower conveyor 122 of the discharge unit 4. This completes the setup work before the start.

  Here, the operator switches the operation mode switch (not shown) provided on the operation panel 20 to “continuous” and then operates the start button. Then, information on the continuous operation start time is written from the control device to the PC, and the continuous operation process described below is started.

A continuous operation process is demonstrated concretely for every process.
A pipe member supply position installation process will be described.

  The stocker 21 of the material supply unit 2 starts to move one pitch at a time toward the worker side in FIG. At the same time, the chuck claw 58a of the chuck mechanism portion 52 constituting the rotary shaft unit 41 provided in the machining unit 3 is switched to an open state in which the corresponding pipe member 10 can pass, and the core adjusting chuck unit 72 The adjustment chuck 75 is also switched to an open state through which the pipe member 10 can pass.

When the pipe member 10 reaches the standby position that is one before the pipe member feeding mechanism section 23 by the movement of the stocker 21, the pipe member diameter measuring section 22 measures the diameter of the pipe member 10. Here, when the diameter of the pipe member 10 matches a preset value, the pipe member 10 is moved toward the pipe member feeding mechanism portion 23. Then, when the pipe member 10 is detected by a sensor (not shown) that the pipe member 10 has been moved to a predetermined position of the pipe member feeding mechanism 23, the installation of the pipe member 10 at the supply position is completed.
In addition, when the pipe member diameter of the pipe member 10 deviates from a preset value, an alarm is displayed and the stocker 21 is switched to a stopped state.

The pipe member feeding process will be described.
When it is detected that the pipe member 10 has been moved to a predetermined position of the pipe member feed mechanism 23, the feed elevator starts to rise and is provided on the pipe member 10 by the grip portion 27 of the feed hand unit 24. The holding jig is gripped. When gripping of the pipe member 10 is detected by a sensor (not shown), the feeding motor 25 is driven to rotate the chain 26 in a predetermined direction. As a result, the material supply hand unit 24 moves on the guide member 28 and the pipe member 10 is gradually fed into the processing unit 3. The pipe member 10 that is fed into the processing unit 3 is formed in the pipe member insertion hole 57a of the rotary shaft rotor 57 provided in the rotary shaft unit 41, the through hole 58c of the chuck body 58b, and the chamber 44. It passes through the rotary shaft unit side opening 82, the second internal space 80, and the pipe member protruding opening 83 and moves toward the contact portion 73 of the stopper unit 71. When the pipe member 10 abuts against the abutting portion 73 of the stopper unit 71, the abutment detecting portion 74 detects that the pipe member 10 has abutted against the abutting portion 73, and is provided in the feeding unit 2. The driving of the feeding motor 25 is stopped. This completes the feeding of the pipe member 10.
In addition, it is comprised so that a feed elevator may descend | fall in order in the middle of feeding of the pipe member 10, ie, whenever the position of the feed hand unit 24 moves and changes.

The process for adjusting the processing position of the pipe member will be described.
When the feeding of the pipe member 10 is stopped, based on a control signal from the control device, first, the adjustment chuck 75 is switched from the open state to the closed state to hold the pipe member 10. Further, the chuck claw 58a of the chuck mechanism 52 is switched from the open state to the closed state, and the pipe member 10 is gripped. Thereafter, the adjustment chuck 75 is again switched from the gripping state to the open state, and the material supply hand unit 24 and the chain 26 of the material supply unit 2 become free. Next, the X-axis moving table 53 on which the rotating shaft unit 41 with the chuck mechanism unit 52 mounted thereon starts moving toward the material supply unit 2 side, and the tip end side of the pipe member 10 is provided in the chamber 44. It is moved to the vicinity of the laser processing position immediately below the laser oscillator insertion / extraction opening 84.

When it is detected that the pipe member 10 has been moved to the laser processing position, the contact portion 73 of the stopper unit 71 disposed on the pipe member moving shaft is retracted, for example, to the back side in a direction away from the operator. Thus, the processing position adjustment of the pipe member 10 is completed.
The contact portion 73 remains in the retracted position continuously until the feeding of a new pipe member 10 is started.

The laser processing process will be described.
When it is detected by a sensor (not shown) that the contact portion 73 has been retracted to a predetermined value, the Z-axis direction moving mechanism portion 67 is driven, and the laser oscillator 65 passes through the laser oscillator insertion / extraction opening 84 and passes through the pipe member 10. Lower to the machining position corresponding to the diameter. Further, the unloader main body 97 provided in the discharge unit 4 is moved on the sliding table 96 to the processing unit 3 side. As a result, the unloader pipe 101 provided in the rotation holding portion 98 and arranged in parallel at a predetermined position passes through the pipe member protruding opening 83 and is arranged at a predetermined position in the through hole of the pipe member 10. That is, the laser oscillator 65 and the attachment member 99 are located in the second internal space 80.

  If the rotary shaft unit 41, the laser oscillator 65, and the unloader pipe 101 are arranged at the machining position, the rotation of the pipe member 10 by the rotation motor unit 51 and the advance / retreat movement of the X-axis moving table 53 by the NC program designated in advance. The laser beam is emitted from the laser oscillator 65 toward the outer surface of the pipe member 10 to perform processing and cutting.

  During processing / cutting by laser light, assist gas is jetted from a nozzle (not shown) provided in the laser oscillator 65 toward the pipe member 10. As the assist gas is ejected, the dross melted by the laser light is scattered from the processing portion. In addition, air from the air blow 89 is supplied to the pipe member 10 to prevent the broken material formed when the pipe member 10 is processed / cut from entering the gap between the pipe member 10 and the mounting member 99. It spouts toward 10. The first dust collector 6 also sucks the dross through the unloader pipe 101, and the second dust collector 7 sucks the dross and broken material scattered in the second internal space 80 through the suction opening 85. .

  As a result, the dross that is melted by the laser light and falls to the through hole side of the pipe member 10 is sucked by the first dust collector 6 through the unloader pipe 101 and is scattered into the second internal space 80 by the assist gas. A part is sucked by the second dust collector 7, and the remaining dross falls from the broken material discharge opening 81 to the broken material collection box 86. Further, the broken material blown off by the air blow falls from the broken material discharge opening 81 to the broken material recovery box 86.

  In the present embodiment, in the second internal space 80 in the chamber 44, the pipe member 10 is irradiated with laser light to perform processing / cutting, and through the suction opening 85 and the unloader pipe 101 provided in the chamber 44. By always collecting the dust during the process, it is possible to reliably prevent the dross and broken material generated during the laser processing from scattering from the second internal space 80 of the chamber 44 to the outside.

  Further, by rotating the rotor 56 by directly connecting the chuck main body 58b constituting the chuck mechanism portion 52 and the rotary shaft rotor 57 to the rotor 56 constituting the rotation motor portion 51, the rotation of the rotor 56 is chucked. The pipe member 10 can also be rotated with the rotation of the rotor 56 by being transmitted directly to the mechanism portion 52. In addition, the pipe member 10 held by the chuck mechanism 52 can be controlled to rotate at high speed. As a result, the processing / cutting speed by the laser beam is greatly improved, and a highly accurate joint piece is processed.

The joint piece taking process will be described.
When the processing / cutting of the joint piece by the NC program is completed, the joint piece is placed on the unloader pipe 101 in a loosely fitted state, and a control signal for notifying that the joint piece has been processed / cut is output from the control device. The Then, the laser light irradiation from the laser oscillator 65 and the ejection of the assist gas are stopped. Thereafter, the Z-axis direction moving mechanism 67 starts moving upward, and the laser oscillator 65 passes through the laser oscillator insertion / extraction opening 84 and is moved to a predetermined position outside the chamber 44. Further, the unloader main body 97 which has been moved and arranged on the processing unit 3 side starts to move in the direction of the joint piece take-out position, and is placed in the through hole of the pipe member 10 and the unloader pipe in a state where the joint piece is placed. 101 passes through the pipe member protruding opening 83 and is moved to the discharge unit 4 side.

  In the state where the unloader body 97 is moving, the movement of the unloader body 97 is detected by the movement position detection sensor 105. Then, the unloader pipe 101 does not collide. For this reason, as preparation for processing the next joint piece, first, the X-axis moving table 53 on which the rotary shaft unit 41 including the chuck mechanism portion 52 for gripping the pipe member 10 is placed is a center adjustment chuck. A predetermined amount is moved to the unit 72 side. Then, the adjustment chuck 75 in the open state is closed and the pipe member 10 is gripped.

  Next, the chuck claw 58a of the chuck mechanism portion 52 that is in the closed state is changed to the open state, and then the X-axis moving table 53 is moved to the feed unit 2 side by the joint piece machining length. As a result, the drawing operation is performed so that the pipe member 10 protrudes from the tip end side of the chuck mechanism portion 52.

  Next, when the movement of the X-axis moving table 53 is completed, the chuck claw 58a is again changed to the closed state and grips the pipe member 10. At this time, the adjustment chuck 75 is opened. This completes the pulling-out operation of the pipe member 10. Thereafter, the X-axis moving table 53 moves again to the material supply unit 2 side, and the tip end side of the pipe member 10 is arranged at the laser processing position. This makes it possible to start processing the next joint piece.

  On the other hand, when it is confirmed that the unloader main body 97 has returned to the joint piece removal position, the rotation holding unit 98 rotates 90 degrees. As a result, the attachment member 99 on which the unloader pipe 101 on which the processed / cut joint piece is placed is stopped in a state in which the attachment member 99 is pointed above the Z axis. Then, the hand 111 disposed on the extension line of the unloader pipe 101 is moved downward by the hand up / down moving mechanism 112. When the opened hand 111 reaches the joint piece collection position, the hand 111 is switched to the closed state. As a result, the joint piece is gripped by the hand 111.

  Next, the hand up / down moving mechanism 112 moves upward and the hand 111 holding the joint piece starts to rise. Then, it is detected that the hand 111 has reached the upper limit by raising the hand 111 by a predetermined amount. Then, the hand 111 is turned toward the drop port 114 by the hand turning mechanism 113, while the rotation holding portion 98 is rotated by 90 ° in the opposite direction to the above and provided again on the attachment member 99. The unloader pipe 101 is in a state where the tip end side is opposed to the pipe member protruding opening 83. At this time, if the above-described pulling-out operation of the pipe member 10 is completed and the pipe member 10 is in the state of being disposed at the machining position, the unloader body 97 is moved to the machining unit 3 side to machine the next joint piece. Moved. As a result, the unloader pipe 101 is again arranged at a predetermined position in the through hole of the pipe member 10, and the processing / cutting of the next joint piece is started.

  If the hand 111 swung by the hand swivel mechanism 113 reaches a predetermined position facing the drop port 114, the swiveling is stopped. Then, the hand 111 is switched from the closed state to the open state. As a result, the joint piece held by the hand 111 falls into the drop port 114, and then passes through the resin pipe member 129 and the recovery port 128 from the drop port 114 and falls into the storage box 127. When the joint piece falls into the storage box 127, the number of joint pieces stored in the storage box 127 is counted by the passage sensor.

  When the joint piece is dropped from the hand 111 at the drop port 114, the hand 111 turns in the opposite direction to the above, returns to the original position, and waits until the next joint piece is processed / cut. Become.

  The joint piece collection process will be described.

  At the same time as the continuous operation process is started, the motor 126b of the lower conveyor 122 is driven, and the empty storage box 127 is moved to the processing unit 3 side. When the empty storage box 127 is moved to the end of the lower conveyor 122, the driving of the motor 126b is stopped. Then, the storage box holder (not shown) is moved to the operator side, and the empty storage box 127 is placed at the lower position and placed on the lifting table 123 a of the storage box elevator 123.

  When the storage box 127 is placed on the lift table 123a, the storage box elevator 123 is driven to raise the lift table 123a to the upper position. When the elevating table 123a reaches the upper position, the storage box pusher 124 pushes the empty storage box 127 toward the collection port 128. Thus, the storage box 127 is disposed on the belt 125a of the upper conveyor 121.

  When the empty storage box 127 is disposed on the upper conveyor 121, the motor 126a of the upper conveyor 121 is driven, and the empty storage box 127 moves directly below the collection port 128, so that a predetermined number in the storage box 127 is obtained. Stay in that position until the joint piece is retracted. As a result, the joint pieces that have passed through the recovery port 128 are stored one by one in the storage box 127.

  When the empty storage box 127 is pushed out to the upper conveyor 121 by the storage box pusher 124 and the storage box 127 is moved from above the lifting table 123a, the lifting table 123a is moved to the lower position.

  When a predetermined number of joint pieces are stored in the storage box 127 disposed immediately below the collection port 128, the motor 126a is driven to move the storage box 127 in which the predetermined number of joint pieces are stored by a predetermined amount. To do. Thereafter, the above-described operation is repeated to place the empty storage box 127 directly below the collection port 128.

The unloader pipe suction hole dross removing step will be described.
A dross suction hose is connected to the unloader pipe 101 constituting the unloader unit 91. For this reason, the dross is fixed to the edge of the suction hole 101a of the unloader pipe 101 and the inner peripheral surface of the unloader pipe 101 by sucking the dross with the unloader pipe 101 through the dross suction hose.

  For this reason, first, the dross fixed to the suction hole 101a of the unloader pipe 101 is removed by the punch portion 141 provided in the second dross unit 95b. Specifically, the tip constituting portion 142 constituting the dross removing mechanism portion 140 in a state where the tip side surface of the unloader pipe 101 is in contact with and held by the abutting surface 131 of the tip holding member 132 constituting the tip holding mechanism portion 130. And the tip of the punch portion 141 provided in the tip constituting portion 142 is disposed in the suction hole 101a. As a result, the dross adhered to the suction hole 101a is removed.

Here, the operation when removing the dross adhered to the edge of the suction hole 101a will be briefly described.
When the hand up / down moving mechanism 112 is operated upward and it is detected that the hand 111 holding the joint piece has risen by a predetermined amount, the hand turning mechanism 113 turns the hand 111. Then, based on the control signal output from the control device, the holding mechanism air cylinder 135 starts to operate. That is, the sliding block 133 located at the standby position starts to move. Then, when the sliding block 133 starts moving, the tip holding member 132 moves toward the tip portion side surface of the unloader pipe 101.

  When the holding mechanism air cylinder 135 moves by a predetermined amount to reach the foremost position, for example, the holding mechanism 131 includes a contact portion 131c and a contact portion 131d provided on the contact surface 131 of the tip holding member 132. The unloader pipe 101 comes into contact with the stepped portion. Then, the tip holding member 132 is moved against the urging force of the urging member. As a result, the contact portion 131c is disposed in contact with the side surface of the tip of the unloader pipe 101. As a result, the side surface of the tip of the unloader pipe 101 is held by the contact surface 131.

  Next, when the movement of the holding mechanism air cylinder 135 to the foremost position is confirmed, the control device operates the removal mechanism air cylinder 143. In other words, the tip constituting portion 142 located at the standby position starts to move, and the punch portion 141 provided in the tip constituting portion 142 moves toward the suction hole 101a of the unloader pipe 101.

  When the removal mechanism air cylinder 143 moves by a predetermined amount and reaches the most advanced position, the tip of the punch portion 141 is disposed in the suction hole 101a. As a result, the dross fixed to the edge portion of the suction hole 101 a of the unloader pipe 101 is removed by the punch portion 141. At this time, the side surface of the tip of the unloader pipe 101 is held by the contact surface 131, so that the acting force of the punch portion 141 can sufficiently act on the dross, and the dross can be removed reliably.

  Next, when the removal mechanism air cylinder 143 moves to the most advanced position, the removal mechanism air cylinder 143 immediately starts moving in the reverse direction. Further, when the control device confirms that the removal mechanism air cylinder 143 has started to move in the reverse direction, it moves the holding mechanism air cylinder 135 in the reverse direction. By these things, the front-end | tip structure part 142 and the sliding block 133 return to a standby position, and will be in a standby state again.

  When it is confirmed by the control device that the removal mechanism air cylinder 143 and the holding mechanism air cylinder 135 have returned to the standby position, it is determined that the unloader pipe suction hole dross removal step is completed, and the rotation holding unit 98 is moved. Rotate to move to the unloader pipe inner surface dross cutting process.

An unloader pipe inner surface dross cutting process is demonstrated.
When the removal of the dross fixed to the edge of the suction hole 101a is completed by the unloader pipe suction hole dross removal step, three to five joint pieces are removed in order to remove the dross fixed to the inner peripheral surface of the unloader pipe 101. Every time processing / cutting is performed, the drill 152 provided in the second dross unit 95b is inserted into the through-hole of the unloader pipe 101 from the tip opening side of the unloader pipe 101 to remove the dross.

  Specifically, in order to first perform dross cutting in the through hole, the inner diameter dimension of the unloader pipe 101 is selected from the multi-axis drill 151 provided with the two types of drills 152 provided in the second dross unit 95b. Select the best drill. The selection switching of the drill is performed by a cylinder (not shown) based on a control signal from the control device.

Here, the operation when removing the dross in the unloader pipe 101 will be briefly described.
When it is confirmed by the control device that the removal mechanism air cylinder 143 and the holding mechanism air cylinder 135 have returned to the standby position, and the unloader pipe suction hole dross removal step is completed, the rotation holding unit 98 rotates 90 degrees. As a result, the attachment member 99 provided with the unloader pipe 101 in which the dross removal of the suction hole 101a is completed is stopped in a state parallel to the X axis, and the opening of the through hole of the unloader pipe 101 faces the drill 152. It will be in the position.

  Next, the control device rotates the drill 152 and moves the second dross unit 95b to the unloader main body 97 side. Then, the rotating drill 152 enters the through hole of the unloader pipe 101 and moves to the foremost position. As a result, the dross fixed to the inner peripheral surface of the unloader pipe 101 is cut off by the rotating drill 152.

  At this time, dross can be reliably removed by repeatedly inserting and removing the drill 152 from and into the through hole of the unloader pipe 101 several times. When the dross removal operation on the inner surface of the unloader pipe 101 is completed, the control device retracts the second dross unit 95b and stops the rotation of the drill 152.

Thereafter, when it is confirmed that the drill 152 is removed from the through-hole of the unloader pipe 101, the rotation holding unit 98 is rotated 180 ° so that the tip of the unloader pipe 101 faces the pipe member protruding opening 83. Then, for the next joint piece processing, the unloader main body 97 is moved to the processing unit 3 side, and the unloader pipe 101 is again arranged at a predetermined position in the through hole of the pipe member 10 to process the next joint piece. Start cutting.
By repeating these steps, joint pieces are continuously produced.

  In this way, by providing the chuck body to which the pipe member gripping part is attached directly connected to the rotor constituting the rotation motor part, by rotating the rotor, the rotation of the rotor is transferred to the pipe member gripping part. The pipe member gripped by the pipe member gripping portion can be rotated with the rotation of the rotor. Thus, the processing / cutting of the joint piece by the laser beam can be performed with high accuracy. In addition, the pipe member gripped by the pipe member gripping portion can be controlled to rotate at high speed. Thus, the processing / cutting of the joint piece by the laser beam can be performed with high accuracy and the processing speed is greatly improved.

  Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention.
