Description

Technical Field

[0001] The utility model relates to a processing system with multiple processing machine units. Background Art

[0002] A processing system for processing a workpiece using a plurality of processing machines is known (Japanese Patent Application Laid-Open No. 8-215976). In this processing system, the plurality of processing machines are arranged around a manipulation device that grips the workpiece.

[0003] In conventional processing systems, it is necessary to accurately position the operating device and each processing machine, which requires time and effort in setup. Utility Model Content

[0004] The purpose of the utility model is to provide a processing system which can be easily set up and has a plurality of processing machine units.

[0005] A first aspect of the present invention is a processing system comprising a processing chamber unit (100) and a processing machine unit (200).

[0006] The processing chamber unit accommodates a workpiece and has:

[0007] a wall portion having a window portion; and

[0008] a transporter, the transporter being surrounded by the wall portion and holding the workpiece to transport the workpiece to a processing position facing the window portion;

[0009] The processing machine unit is arranged so as to block the window portion, and includes a processing portion that passes through the window portion and processes the workpiece located at the processing position.

[0010] The workpiece is made of metal, for example. Examples of the metal constituting the workpiece include aluminum alloys, magnesium alloys, titanium, titanium alloys, heat-resistant alloys, and steel. The workpiece is, for example, a machine component. For example, the machine component is an automotive component.

[0011] Both the processing chamber unit and the processing machine unit can be transported as a unit. However, a unit can also be divided into multiple parts.

[0012] The wall portion surrounds the transporter. The processing chamber unit may also have a top portion on the upper side of the wall portion. The processing chamber unit may also not have a top portion. Preferably, the processing chamber unit has a lower surface portion on the lower side of the wall portion.

[0013] The wall portion as a whole may be cylindrical. It may also be formed by combining multiple planar walls. For example, the wall portion may be in the shape of a square cylinder. It may also be formed by a curved wall. For example, the wall portion may be in the shape of a cylinder. It may also be formed by combining a planar wall and a curved wall.

[0014] The window portion of the wall portion is a component with a partially open wall portion. The window portion is sized and shaped to allow the processing unit of the processing machine unit to pass through. When the processing unit moves, the window portion can be sized and shaped to correspond to the range of movement of the processing unit.

[0015] The transporter holds the workpiece. The transporter is a mechanism that fixes the workpiece with fasteners such as bolts or clamps, or clamps and fixes the workpiece. The transporter moves the held workpiece. The transporter can be a mechanism that rotates the workpiece. The transporter is, for example, an indexing table. The transporter can be a mechanism that moves the workpiece in translation. The transporter is, for example, a pallet or a belt conveyor. In the case where the processing chamber unit has a lower surface portion, the transporter can be installed on the lower surface portion. In the case where the processing chamber unit does not have a lower surface portion, the transporter can be installed on a beam, for example, and the beam can be fixed to the wall portion.

[0016] The number of processing machine units can be the same as the number of windows on the wall surface of the processing chamber unit. The number of processing machine units can also be less than the number of windows. In this case, the windows not blocked by the processing machine units can be blocked by other blocking components. The processing machine unit can also have one or more processing parts.

[0017] The processing unit performs cutting, grinding, electrical discharge machining, laser machining, and the like. The processing unit can move through the window into the processing chamber unit to process a workpiece. For example, the processing unit may include a spindle and a tool mounted on the spindle. Each processing unit may perform the same type of processing. Alternatively, each processing unit may perform different types of processing.

[0018] At a processing position, a workpiece passes through a window and is processed by the processing unit. The processing position can also be located at different locations depending on the type of processing unit in the processing machine unit. A single processing position can face multiple windows. In this case, the workpiece can be processed simultaneously by the processing units of multiple processing machine units.

[0019] The shielding portion prevents chips or coolant from scattering from the processing chamber through the window toward the processing unit. Preferably, when viewing the window from the processing chamber, only the processing unit, other than the shielding portion, is exposed through the shielding portion. Preferably, the shielding portion covers the rest of the processing unit. When the processing unit moves, the shielding portion can expand and contract in response to the movement of the processing unit. Examples of the shielding portion include a bellows, a telescopic cover, or a roller cover.

[0020] When the processing part has a spindle and a tool, the processing machine unit may have an automatic tool changer (ATC). The ATC may be located at a position closer to the processing chamber unit side than the wall portion. The ATC may be located in the replacement chamber through a window portion. The partition wall may substantially completely separate the space surrounded by the wall portion. The partition wall may not completely separate the space surrounded by the wall portion, leaving a gap. The partition wall may have a connecting portion such as a door or a window that communicates with the processing chamber and the replacement chamber. The receiving portion can recover chips or coolant.

[0021] The protruding wall of the processing unit may have a tool change port for the ATC to replace the spindle's tool. A portion of the ATC may protrude from the tool change port toward the area where the spindle is located. The ATC may have a gate that blocks the tool change port during processing (not during tool change).

[0022] The processing chamber may have an inlet and an outlet. The inlet and the outlet are located on the wall and the ceiling. The inlet and the outlet may be located continuously from the wall to the ceiling. The inlet and the outlet may have an opening and closing portion. The opening and closing portion opens and closes the inlet and the outlet. Examples of the opening and closing portion include a gate or a door.

[0023] According to the present invention, it is possible to provide a machining system that can be easily installed and includes a plurality of machining machine units. BRIEF DESCRIPTION OF THE DRAWINGS

[0102] Next, the table 32 is rotated 90 degrees clockwise. As a result, the workpiece 10 moves to the first processing position 41. The four processing units 60 of the processing machine unit 200u process the workpiece 10 at the first processing position 41.

[0103] Next, the table 32 is rotated 90 degrees clockwise. As a result, the workpiece 10 moves to the second processing position 42. The four processing units 60 of the processing machine unit 200v process the workpiece 10 at the second processing position 42.

[0104] Next, the table 32 is rotated 90 degrees clockwise. As a result, the workpiece 10 moves to the third processing position 43. The four processing units 60 of the processing machine unit 200w process the workpiece 10 at the third processing position 43.

[0105] Next, the table 32 is rotated 90 degrees clockwise. This causes the workpiece 10 to move to the carry-in position 44. The workpiece 10 at the carry-in position 44 is removed from the gripping portion 35. The workpiece 10 is then carried out of the processing chamber 120 through the carry-in port 22.

[0106] When processing is performed using each processing machine unit 200, the tool 62 of the spindle 61 is replaced by the ATC80 as needed. When the operator performs maintenance or other operations on the ATC80, the operator can enter the replacement chamber 130 through the door 140. The chips or coolant (hereinafter referred to as chips, etc.) generated by the processing of the workpiece 10 falls to the receiving part 501 on the lower side of the processing part 60. Then, the chips, etc. flow along the slope of the receiving part 501 and are recovered to the chip recovery part (not shown). The chips, etc. can be recovered in the processing chamber unit 100. The chips, etc. can be recovered in each processing machine unit 200. Since the processing chamber 120 and the replacement chamber 130 are separated by the partition wall 14, the chips, etc. generated in the processing chamber 120 are suppressed from flying to the ATC80. A revolving door structure is formed by the rotating wall 302 and the partition wall 14. Thus, in the processing chamber 120, the space where adjacent workpieces 10 exist is separated by the rotating wall 302. Therefore, it is possible to suppress chips and the like generated by machining the workpiece 10 from being scattered toward the adjacent workpiece 10 .

[0107] According to the machining system 1 of this embodiment, by installing the machining unit 200 corresponding to the window portion 21, the machining portion 60 faces the machining position 40 of the workpiece 10. This facilitates positioning work during installation.

[0108] The processing chamber unit 100 includes a wall portion 11 and a window portion 21. The processing machine unit 200 includes 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 shield. The mechanical portion 85 can be separated from the processing chamber 120. Therefore, a liquid processing coolant can be used in the processing portion 60.

[0109] The processing chamber unit 100 includes a partition wall 14 and an inner wall surface 117. The processing machine unit 200 includes 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 replacement chamber 130. This prevents chips or coolant generated in the processing chamber 120 from entering the replacement chamber 130.

[0110] The processing chamber unit 100 includes a partition wall 14, an inner wall surface 117, and a transporter 30. The processing machine unit 200 includes a mechanical unit 85, a processing unit 60, an ATC 80, and a receiving unit 501. The components surrounding the processing unit 60 are concentrated in the processing machine unit 200, while the components related to the transporter 30 and the processing chamber 120 are concentrated in the processing chamber unit 100. This allows for easy disassembly, transport, and reassembly of the processing system 1.

[0111] The multiple processing machine units 200 have a common (general) structure. The processing machine unit 200 has multiple common components such as the column 63, the processing unit 60, the ATC 80, the protruding wall 56, etc. The processing chamber unit 100 and the rotating conveying unit 31 are also composed of multiple groups (in Figure 1 The common components are four groups in each case. Therefore, the number of spare parts and inventory required for the processing system 1 can be reduced. In addition, maintenance is also facilitated.

[0112] The door 140 faces the replacement chamber 130. The ATC 80 is arranged in the replacement chamber 130. The operator can enter the replacement chamber 130 through the door 140. Thus, the operator can perform maintenance on the ATC 80 and replace the tool 62. When the connecting portion is arranged on the partition wall 14, the operator can maintain the rotary conveying portion 31 through the connecting portion. Figure 1 The ATC80s (two or four in total) are centrally arranged in one replacement chamber 130, making maintenance easier.

[0113] As cars become more electric, the demand for machining large parts is increasing. The number of large flat-plate or tray-shaped workpieces is increasing. The transporter 30 of this embodiment can set the workpieces 10 upright, thus reducing the installation area of ​​the machining system 1.

[0114] By changing the shape and structure of the processing chamber unit 100 and the arrangement of the processing machine unit 200 , the layout of the machine and the processing capacity can be easily changed.
