[Technical field]

[0001] The present invention relates to a processing system having a plurality of processing machine units. [Background technology]

[0002] 2. Description of the Related Art As a machining system for machining a workpiece using a plurality of machining machines, a machining system in which a plurality of machining machines are arranged around a handling device that grips the workpiece has been disclosed (JP Patent Publication No. 8-215976). Summary of the Invention [Problem to be solved by the invention]

[0003] In such a conventional processing system, accurate positioning between the handling device and each processing machine is required, and installation is time-consuming. An object of the present invention is to provide a processing system having a plurality of processing machine units, which is easy to install. [Means for solving the problem]

[0004] The first aspect of the present invention is A processing chamber unit for accommodating a workpiece, A wall portion; A window portion disposed on the wall portion; a conveyor that is disposed surrounded by the wall surface portion, grips the workpiece, and conveys the workpiece to a processing position facing the window portion; A processing chamber unit having a processing machine unit having a processing section that processes the workpiece located at the processing position through the window section and is disposed so as to close the window section; A processing system including:

[0005] The workpiece is, for example, made of a metal. The metal constituting the workpiece is, for example, an aluminum alloy, a magnesium alloy, titanium, a titanium alloy, a heat-resistant alloy, or steel. The workpiece is, for example, a machine part. The machine part is, for example, an automobile part.

[0006] The processing chamber unit and the processing machine unit can be handled as a unit for transport, etc. However, one unit may be divisible into multiple parts.

[0007] The wall surface portion is disposed so as to surround the transport device. The processing chamber unit may have a ceiling portion provided above the wall surface portion. The processing chamber unit does not have to have a ceiling portion. Preferably, the processing chamber unit has a lower surface portion provided below the wall surface portion.

[0008] The wall surface portion may be generally cylindrical. The wall surface portion may be configured by combining a plurality of planar walls. For example, the wall surface portion may be rectangular tubular. The wall surface portion may be configured by curved walls. For example, the wall surface portion may be cylindrical. The wall surface portion may be configured by combining a planar wall and a curved wall.

[0009] The window of the wall is an opening in a part of the wall. The window has a size and shape that allows the processing part of the processing machine unit to pass through. When the processing part moves, the window may have a size and shape according to the movement range of the processing part.

[0010] The conveying machine grips the workpiece. The conveying machine is, for example, a machine that fixes the workpiece with fasteners such as bolts and clamps, or a machine that clamps and fixes the workpiece. The conveying machine moves the gripped workpiece. The conveying machine may be a machine that rotates and moves the workpiece. A conveying machine that rotates and moves the workpiece is, for example, an index table. The conveying machine may be a machine that translates and moves the workpiece. A conveying machine that translates and moves the workpiece is, for example, a pallet or a conveyor. If the processing chamber unit has a bottom surface, the conveying machine may be attached to the bottom surface. If the processing chamber unit does not have a bottom surface, for example, the conveying machine may be attached to a beam material, and the beam material may be fixed to a wall surface.

[0011] The number of processing machine units may be the same as the number of windows in the wall of the processing chamber unit. The number of processing machine units may be less than the number of windows in the wall of the processing chamber unit. When the number of processing machine units is small, the windows that are not blocked by the processing machine units may be blocked by another blocking member.

[0012] The processing performed by the processing section of the processing machine unit may be cutting, grinding, electric discharge processing, laser processing, etc. The processing section may move into the processing chamber unit through the window section to process the workpiece. The processing section may have, for example, a spindle and a tool attached to the spindle. The processing machine unit may have one processing section. The processing machine unit may have multiple processing sections. When the processing machine unit has multiple processing sections, each processing section may perform the same type of processing. When the processing machine unit has multiple processing sections, each processing section may perform different types of processing.

[0013] The processing position is a predetermined position where the workpiece is processed by the processing section of the processing machine unit through the window section of the wall section. The processing position may be a different position depending on the type of the processing section of the processing machine unit. One processing position may face multiple window sections. In this case, the workpiece may be processed simultaneously by the processing sections of multiple processing machine units.

[0014] The shielding portion prevents chips and coolant from scattering from the machining chamber through the window portion toward the machining unit. Preferably, when the window portion is viewed from the machining chamber, only the machining portion among the components of the machining unit other than the shielding portion is exposed from the shielding portion. Preferably, the shielding portion covers other areas of the machining unit. When the machining portion moves, the shielding portion may expand and contract in accordance with the movement of the machining portion. The shielding portion is, for example, a bellows, a telescopic cover, or a roll cover.

[0015] When the machining section has a spindle and a tool, the machining unit may have an automatic tool changer (ATC). The ATC may be located closer to the processing chamber unit than the wall section. The ATC may be located inside the exchange chamber through the window section. The partition wall may substantially completely separate the space surrounded by the wall section. The partition wall may not completely separate the space surrounded by the wall section, leaving a gap. The partition wall may have a communication section such as a door or window that leads to the machining chamber and the exchange chamber.

[0016] The protruding wall of the processing machine unit may have a tool exchange opening through which the ATC exchanges the tool of the spindle. A part of the ATC may protrude from the tool exchange opening into an area where the spindle is provided. The ATC may have a shutter that closes the tool exchange opening during processing (when not exchanging tools).

[0017] The processing chamber may have a loading / unloading port, a loading / unloading port, or a loading / unloading port. The loading / unloading port, the loading / unloading port, or a loading / unloading port may be disposed in a wall portion or a ceiling portion. The loading / unloading port, the loading / unloading port, or a loading / unloading port may be disposed continuously from the wall portion to the ceiling portion. The loading / unloading port, the loading / unloading port, or a loading / unloading port may have an opening / closing portion. The opening / closing portion opens and closes the loading / unloading port, the loading / unloading port, or a loading / unloading port. The opening / closing portion is, for example, a shutter or a door. Effect of the Invention

[0018] According to the processing system of the present invention, the processing machine unit can be easily installed by aligning it with the window portion in the wall surface of the processing chamber unit. [Brief description of the drawings]

The transport device 30 is disposed integrally with the central portion 104.

[0046] A method for machining the workpiece 10 using the machining system 1 will be described. First, the workpiece 10 is carried into the processing chamber 120 through the carry-in / out opening 22. Then, at the carry-in / out position 44, the workpiece 10 is gripped by the gripping portion 35 of the rotary transport portion 31. Next, the table 32 of the rotary transport section 31 is rotated 90 degrees clockwise. The workpiece 10 moves to the first processing position 41. The four processing sections 60 of the processing machine unit 200u process the workpiece 10 at the first processing position 41. Next, the table 32 of the rotary transport section 31 is rotated 90 degrees clockwise. The workpiece 10 moves to the second processing position 42. The four processing sections 60 of the processing machine unit 200v process the workpiece 10 at the second processing position 42. Next, the table 32 of the rotary transport section 31 is rotated 90 degrees clockwise. The workpiece 10 moves to the third processing position 43. The four processing sections 60 of the processing machine unit 200w process the workpiece 10 at the third processing position 43. Next, the table 32 of the rotary transfer unit 31 is rotated 90 degrees clockwise. The workpiece 10 moves to the load / unload position 44. The workpiece 10 at the load / unload position 44 is removed from the gripper 35 of the rotary transfer unit 31. Then, the workpiece 10 is unloaded from the load / unload opening 22 to the outside of the processing chamber 120.

[0047] When machining is performed by the machining section 60 of each machining unit 200, the tool 62 of the spindle 61 is replaced by the ATC 80 as necessary. When an operator performs maintenance or other work on the ATC 80, the operator enters the exchange chamber 130 through the door 140 and performs the work. Chips and coolant (hereinafter referred to as chips, etc.) generated by machining the workpiece 10 fall into the receiving section 501 below the machining section 60. The chips, etc. are then slid along the slope of the receiving section 501 and are collected from the discharge port 502 to a collection section (not shown) further below. The chips, etc. may be collected in the processing chamber unit 100. The chips, etc. may be collected in each machining unit 200. The machining chamber 120 and the exchange chamber 130 are separated by the partition wall 14, so that scattering of chips, etc. generated in the machining chamber 120 to the ATC 80 is suppressed. A revolving door structure is arranged by the rotating wall 302 and the partition wall 14, and within the processing chamber 120, a space in which one workpiece 10 exists and a space in which an adjacent workpiece 10 exists are separated by the rotating wall 302. This prevents chips and the like generated by the processing of one workpiece 10 from scattering to the adjacent workpiece 10.

[0048] According to the processing system 1 of this embodiment, by installing the processing machine unit 200 in alignment with the window portion 21 of the wall portion 11 of the processing chamber unit 100, the processing section 60 faces the processing position 40 of the workpiece 10. This makes it easy to perform positioning work during installation. The processing chamber unit 100 has a wall portion 11 and a window portion 21. The processing machine unit 200 has a bellows 70. When the processing machine unit 200 is connected to the processing chamber unit 100, the window portion 21 is covered by the bellows 70. This forms a splash cover. The machine portion 85 can be separated from the inside of the processing chamber 120. Therefore, a liquid processing coolant can be used in the processing section 60. The processing chamber unit 100 has a partition wall 14 and an inner wall surface 117, and the processing machine unit 200 has a protruding wall 56. When the processing machine unit 200 is connected to the processing chamber unit 100, the partition wall 14 and the inner wall surface 117 are connected to the protruding wall 56. This forms the processing chamber 120 and the exchange chamber 130. The intrusion of chips and coolant generated in the processing chamber 120 into the exchange chamber 130 is suppressed. The processing chamber unit 100 has a partition wall 14, an inner wall surface 117, and a transport machine 30. The processing machine unit 200 has a machine section 85, a processing section 60, an ATC 80, and a receiving section 501. By concentrating the elements around the processing section 60 in the processing machine unit 200 and concentrating the elements related to the transport machine 30 and the processing chamber 120 in the processing chamber unit 100, the processing system 1 can be easily disassembled, transported, and reassembled. The multiple processing machine units 200 have a common structure. The processing machine units 200 have multiple common parts such as the pillar body 63, the processing section 60, the ATC 80, and the protruding wall 56. The processing chamber unit 100 and the rotary transport section 31 are also composed of multiple sets of common parts (four sets each in FIG. 1). This allows the number of spare parts required for the processing system 1 and the number of parts in stock to be reduced. Maintenance is also made easier. A door 140 faces the exchange room 130. The ATC 80 is disposed in the exchange room 130. An operator can enter the exchange room 130 through the door 140, and thus the operator can perform maintenance on the ATC 80 and replace the tool 62. When a communication part is disposed in the partition wall 14, the operator can perform maintenance on the rotary conveying unit 31 through the communication part. Since multiple ATCs 80 (two or four in FIG. 1 ) are concentrated in one exchange room 130, maintenance is facilitated. The shift to electric vehicles has led to an increased need for machining large parts. The number of large workpieces in the form of flat plates or trays is on the rise. The conveyor 30 of this embodiment can install the workpiece 10 upright, so that the installation area of ​​the machining system 1 can be reduced. By changing the shape and structure of the processing chamber unit 100 and the arrangement of the processing machine unit 200, the layout and processing capacity of the machine can be easily changed.
