Description

Technical Field

[0001] The present invention relates to a processing device, a workbench for the processing device, and a method for connecting the workbench for the processing device. Background Art

[0002] A cutting plotter is a processing device that forms cutting lines or V-grooves on an object by pressing a cutting tool (cutter) against the object and moving the tool relative to the object.

[0003] For example, when the object to be processed is a label sticker whose adhesive surface is covered with release paper, the cutting plotter forms a cutting line on the label sticker on which information such as text or pattern is printed so as to surround an area of ​​the text or pattern.

[0004] The cutting line is formed while the cutting tool is relatively displaced relative to the workpiece placed on the table in two directions (X and Y) along the horizontal line of the table surface and one direction (Z) along the vertical line.

[0005] Here, among the inkjet printing devices, there is a printing device that includes a mechanism for displacing a carriage on which an inkjet head is mounted in the Y direction and a mechanism for displacing the carriage in the X direction.

[0006] In this inkjet printer, the Y-direction displacement of the inkjet head, which accompanies the Y-direction displacement of the carriage, and the X-direction displacement of the medium are controlled, causing the inkjet head and the medium on the stage to be displaced relative to each other in two directions (X and Y). In this manner, the inkjet printer prints information such as text and images on the medium by ejecting ink droplets from the inkjet head toward the medium (e.g., Patent Document 1).

[0007] Prior art literature

[0008] Patent Literature

[0009] Patent Document 1: Japanese Patent Application Laid-Open No. 2019-181916

[0010] By mounting a cutting tool (cutter) on a carriage instead of an inkjet head, the cutting tool and the object to be processed can be relatively displaced in the X direction and the Y direction.

[0011] However, compared to the case of displacing the inkjet head, the displacement speed (acceleration) when displacing the cutting tool is greater, and the vibration of the device accompanying the movement of the cutting tool is greater.

[0012] Therefore, if the tool is simply replaced with a cutting tool, there is a possibility that vibration will affect the accuracy of relative movement in the X direction and the Y direction. Therefore, it is preferable to be able to process the object appropriately.

[0013] Furthermore, without being limited to such requirements, achieving functions and effects derived from the various configurations disclosed in the “Detailed Description of the Invention” described later and not obtained in conventional technologies can also be considered as other purposes of the present invention.

[0014] Furthermore, in this case, the processing apparatus processes the object using a dedicated tool determined according to the processing method of the object. Therefore, in the processing apparatus, it is necessary to change the tool according to the processing method.

[0015] In particular, there are many V-grooves with different slopes in the V-grooves formed in the workpiece. Therefore, it is necessary to prepare a plurality of tools with different blade inclinations according to the slopes of the V-grooves to be formed, and the tool must be replaced every time the V-groove to be formed is changed.

[0016] When a tool for forming a V-groove is mounted on a machining device, the tool tip must be positioned with high precision. This increases the cost of replacing the tool.

[0017] Furthermore, if the positional accuracy is poor, there is a possibility that the processing accuracy of the object to be processed may be affected. Summary of the Invention

[0018] Solutions for solving problems

[0019] The present invention is

[0020] (1) A processing device having the following structure:

[0021] The processing device has:

[0022] a workbench on which a workpiece is placed;

[0023] a support portion that supports a tool for processing the object and moves along a support beam; and

[0024] A driving mechanism causes the support portion to move relative to the workbench, wherein:

[0025] The driving mechanism comprises:

[0026] a Y-direction driving mechanism that moves the support portion in the Y-direction along the support beam; and

[0027] an X-direction driving mechanism that moves the support beam in an X-direction that is a direction orthogonal to the Y-direction along the upper surface of the worktable,

[0028] The table includes a placement portion for placing the workpiece and legs supporting the placement portion from below, wherein the legs are spaced apart in the X direction and the Y direction.

[0029] A shake suppression member is provided between any one of the legs and the other legs or between the leg and the placement portion. The shake suppression member suppresses shake of the table in both the X and Y directions as the support portion and the support beam are moved by the drive mechanism.

[0030] If it is constituted in this way, the shaking of the workbench can be preferably suppressed. Therefore, the degree to which the vibration generated when processing the processing object affects the processing of the processing object can be suppressed, and the processing object can be processed more appropriately.

[0031] (2) The processing device according to (1) above, wherein:

[0032] The workbench is formed by connecting at least two common workbench units in the X direction.

[0033] The connecting mechanism connecting the common work tables to each other is composed of protrusions and recesses.

[0034] The protrusions mentioned above protrude from a common workbench in the X direction,

[0035] The above-mentioned recess is provided on another common workbench and is for the protrusion to be embedded in.

[0036] A plurality of the connection mechanisms are provided at intervals in the Y direction.

[0037] With this configuration, the relative displacement of the connected worktables in the Y direction is suppressed by the connection mechanism. Furthermore, the mass of the worktable formed by connecting the two worktables is greater than the mass of the processing tool and the support portion supporting the tool. Therefore, the worktable is less susceptible to vibration caused by the movement of the support portion, and vibration of the object T placed on the worktable can be suppressed.

[0038] Therefore, the degree to which the vibration caused by the movement of the support portion affects the accuracy when the support portion is moved relative to the object to be processed can be suppressed. Therefore, the object to be processed can be processed more appropriately.

[0039] (3) The processing device according to (1) or (2) above, wherein:

[0040] The processing device has a guide rail for guiding the movement of the support beam along the X direction.

[0041] In the one common worktable, the guide rail is provided along the X direction and is arranged linearly with a gap in the X direction from the guide rail of the other common worktable to which it is connected.

[0042] The processing device includes a connecting guide rail that is inserted between the pair of guide rails arranged in a straight line and connects the guide rail on the one common table side and the guide rail on the other common table side.

[0043] According to this structure, since the guide rails of the two connected tables are connected via the connecting guide rail, the guide rail for guiding the movement of the support beam in the X direction is continuously provided across the two connected tables.

[0044] The continuous guide rail limits the relative displacement of the two connected worktables, and the rigidity of each connected worktable is improved. Therefore, the degree to which vibration caused by the movement of the support portion in the Y direction affects the accuracy of the relative movement of the tool with respect to the processing object can be suppressed.

[0045] (4) The processing device according to (3) above, wherein:

[0046] The X-direction driving mechanism comprises a gear for rotational driving and a rack for meshing with the gear.

[0047] In the one common table, the rack rail is provided along the X direction and is linearly arranged with a gap in the X direction from the rack rail on the other common table side to which it is connected.

[0048] The processing device includes a connecting rack that is inserted between the pair of racks arranged linearly and connects the rack on the one common table side and the rack on the other common table side.

[0049] According to this structure, the racks of the two connected tables are connected via the connecting rack, so the rack for moving the support beam in the X direction is continuously provided across the two connected tables.

[0050] The continuous rack rail limits the relative displacement of the two connected worktables, thereby increasing the rigidity of each connected worktable. This reduces the impact of vibration caused by tool movement in the Y direction on the accuracy of relative movement of the tool with respect to the workpiece.

[0051] (5) The processing device according to (4) above, wherein:

[0052] In each of the common work tables, the guide rail and the rack rail are provided on both sides of each of the connecting mechanisms in the Y direction.

[0053] According to this structure, the guide rail and the rack rail are arranged on one side and the other side with the coupling mechanism interposed therebetween.

[0054] In the Y direction, the connection mechanism is located between the guide rail and the rack rail, and the relative displacement of the two connected worktables to one side and the other side in the Y direction is limited by the guide rail and the rack rail.

[0055] Therefore, the vibration of the entire work table obtained by connecting the two work tables can be preferably suppressed.

[0056] (6) The processing device according to any one of (1) to (5) above, wherein:

[0057] In the workbench,

[0058] A plurality of communication holes are opened on the mounting surface of the workpiece so as to connect the inside and the outside of the table.

[0059] The workbench has an insertion port for inserting a connector on the negative pressure generating member side on the back side opposite to the placement surface.

[0060] The connector has:

[0061] a base portion having one end in the longitudinal direction thereof being closed; and

[0062] a through hole that penetrates the base in a radial direction,

[0063] One end of the base is arranged inside the workbench opposite to the placement surface.

[0064] The through hole is provided in a region of the base portion located inside the workbench.

[0065] The through hole is a long hole along the insertion direction of the base portion into the insertion port, and a plurality of the communicating holes are provided in the base portion at intervals in the circumferential direction.

[0066] With this structure, when the negative pressure generating member is driven, the air inside the worktable is drawn toward the negative pressure generating member via the connector, generating negative pressure inside the worktable. This draws in outside air through the communication holes opening into the loading surface, restricting the movement of the workpiece placed on the loading surface.

[0067] Since one end of the base is closed, attraction is not generated only in the area of ​​the mounting surface opposite the base, thereby suppressing variations in attraction generated on the mounting surface. Therefore, the supported object can be reliably held on the mounting surface, allowing for more appropriate processing of the object.

[0068] The present invention is

[0069] (7) A workbench for a processing device, which is formed by connecting at least two common workbenches in a first direction, wherein:

[0070] Each of the shared workbenches has:

[0071] A workbench surface on which the object to be processed is placed;

[0072] a workbench base supporting the workbench surface; and

[0073] a plurality of legs supporting the workbench base,

[0074] A mounting portion having a protrusion protruding along the first direction is provided at one end of the table base, and a recess into which the protrusion can be fitted from the first direction is provided at the other end.

[0075] The legs are provided with casters for movement and stoppers for positioning.

[0076] If constituted like this, then the projection of another workbench is inserted into the recess of a workbench to complete the connection between the shared workbenches. By possessing the casters used for movement, the movement of the shared workbench becomes easy, and the time required for the connection between the shared workbenches shortens.

[0077] Therefore, even if the total number of connected common workstations increases, the time required to connect the common workstations does not increase significantly, and thus the total number of common workstations can be easily increased.

[0078] (8) The workbench for the processing device according to (7) above, wherein:

[0079] When the direction perpendicular to the first direction along the upper surface of the workbench table is referred to as the second direction, the legs are respectively provided on one end side and the other end side of the workbench base in the first direction, and on one side edge side and the other side edge side in the second direction,

[0080] When the center side of the table base in the second direction is referred to as an inner side and the opposite side is referred to as an outer side, the stopper of each of the legs is located outside of the caster.

[0081] According to this structure, after the common tables are connected to each other, the stoppers can be quickly operated to position the common tables.

[0082] (9) The workbench for the processing device according to (8) above, wherein:

[0083] The casters and the stoppers are provided so as to be positionally adjustable in a vertical direction with reference to an installation state of the common workbench.

[0084] According to the above-described configuration, the height and inclination of the common work table can be easily adjusted, and thus the time required for connecting the common work tables can be shortened.

[0085] (10) The workbench for a processing device according to (8) or (9), wherein:

[0086] The workbench base has rails arranged along the first direction on both sides in the second direction.

[0087] Each of the rails is provided in a range from one end to the other end of the workbench base in the first direction.

[0088] Each of the tracks has:

[0089] Mounting and disassembly rails, which are respectively provided on the one end side and the other end side of the workbench base in a manner that allows for easy installation and removal;

[0090] a fixed rail fixed to a portion of the workbench base between the mounting and removal rail on the one end side and the mounting and removal rail on the other end side; and

[0091] The connecting rail is installed across the connected common work table and the other common work table when the common work tables are connected, replacing the mounting and dismounting rail of the one common work table and the mounting and dismounting rail of the other common work table.

[0092] According to this structure, when a plurality of common work tables are connected in the first direction, work tables of a common specification can be used.

[0093] By adopting a work table of common specifications, it is expected that production costs can be reduced by sharing parts.

[0094] The present invention is

[0095] (11) A method for connecting a common workbench, which is a method for connecting a workbench for a processing device according to (10), wherein:

[0096] The connection method includes the following steps: removing the attachment and detachment rails on one end side of a common workbench to be connected and the attachment and detachment rails on the other end side of another common workbench to be connected;

[0097] bringing one end of the common table to be connected closer to the other end of another common table to be connected;

[0098] inserting the protrusion of the common workbench of the connection object into the recess provided at the other end of the other common workbench to position the common workbench of the connection object;

[0099] actuating a stopper of the common worktable of the connection object to fix the positional relationship between the other common worktable and the common worktable of the connection object; and

[0100] The connecting rail is installed between the fixed rail of the common workbench of the connection object and the fixed rail of the other common workbench to complete the rail from one end of the other common workbench to the other end of the common workbench of the connection object.

[0101] According to this structure, by attaching the connection rail to the common table, it is possible to easily provide the rail extending over the entire length in the connection direction of the common tables connected to each other.

[0102] Furthermore, since it is not necessary to separately prepare rails of different lengths depending on the number of common tables to be connected, the time required for connecting the common tables can be shortened.

[0103] In addition, the present invention is

[0104] (12) A processing device comprising:

[0105] Tools for processing objects; and

[0106] A drive mechanism causes the tool to reciprocate in a linear direction, wherein

[0107] The tool holds the cutting tool,

[0108] The tool includes an angle adjustment mechanism capable of adjusting the angle at which the tool is held.

[0109] The angle adjustment mechanism is provided with a plurality of positioning components corresponding to the angle, and these positioning components position the tool and fix the tool at the positioned position.

[0110] The plurality of positioning members are provided at positions such that when the tool is positioned and fixed, the position of the tool tip is constant regardless of the angle.

[0111] If constituted like this, then even if the angle of the tool is changed, the position of the tool tip can always be configured at the same position. Therefore, there is no need to adjust the position of the tool tip every time the angle of the tool is changed, so the processing accuracy of the processing object can be ensured.

[0112] (13) The processing device according to (12) above, wherein:

[0113] The blade is configured to extend in a plate-like shape toward the blade tip.

[0114] A connecting piece having a shape that is curved toward the positioning member is arranged between the positioning member and the blade edge from a midway in the extending direction of the blade.

[0115] With this configuration, it is not necessary to adjust the position of the tool tip every time the angle of the tool is changed, and thus it is possible to ensure the processing accuracy of the workpiece.

[0116] (14) The processing device according to (12) or (13) above, wherein:

[0117] The tool has:

[0118] a tool holder that supports the tool; and

[0119] a mounted member having a mounting surface for the tool holder,

[0120] A plurality of pairs of engaging points serving as the positioning components are provided on the mounting surface.

[0121] When the tool holder is mounted on the mounting surface using the selected pair of engagement points, the tool held by the tool holder is arranged at an angle determined by the selected pair of engagement points.

[0122] If constructed in this way, a pair of engagement points that match the angle of the tool is selected from multiple pairs of engagement points on the mounting surface, and the tool holder is mounted on the mounting surface of the mounted component using the selected pair of engagement points, thereby enabling the tool to be configured at a desired angle.

[0123] Therefore, the angle of the tool is determined according to the selected pair of engagement points, so the tool can be arranged at a desired angle with high precision by only selecting a pair of engagement points. Therefore, it is possible to preferably prevent a decrease in machining accuracy caused by the contact of the tool angle.

[0124] (15) The processing device according to (14) above, wherein:

[0125] When viewed from the installation direction of the tool holder toward the installation surface,

[0126] The pair of engagement points consists of a first engagement point and a second engagement point,

[0127] The first engagement point is located on a first imaginary circle centered at the tip of the tool supported by the tool holder mounted on the mounting surface, and the second engagement point is located on a second imaginary circle having a diameter smaller than that of the first imaginary circle and being concentric with the first imaginary circle.

[0128] The first engagement point and the second engagement point forming a pair on the mounting surface are arranged with their phases shifted in the circumferential directions of the first imaginary circle and the second imaginary circle.

[0129] If constituted like this, then even if a pair of engagement points selected are changed, the position of the tool tip can always be configured at the same position. Thus, there is no need to adjust the position of the tool whenever the processing method changes, so even if the processing method changes, the processing accuracy of the object can be guaranteed.

[0130] (16) The processing device according to (14) or (15), wherein:

[0131] The tool holder has a pair of engagement points at a portion opposite to the mounting surface.

[0132] The tool holder is mounted on the mounting surface such that a pair of engagement points on the tool holder side matches a pair of engagement points selected on the mounting surface.

[0133] (17) The processing device according to (16) above, wherein

[0134] The mounted member is a plate-shaped member having the mounting surfaces on both sides in the thickness direction.

[0135] According to this structure, the mounted member has two mounting surfaces, and the degree of freedom in setting the inclination of the tool mounted to the mounted member via the tool holder is improved.

[0136] (18) The processing device according to any one of (14) to (17) above, wherein:

[0137] In the mounted member, the tool holder is positioned by an engagement pin spanning an engagement point on the mounting surface side and an engagement point on the tool holder side.

[0138] According to this structure, the tool holder can be easily positioned on the mounted member simply by arranging the engagement pin so as to straddle the hole at the engagement point provided on the mounting surface side and the hole provided on the tool holder side.

[0175] In addition, Figure 1 The example in FIG shows a case where there is only one workbench 2B for expansion. The total number of workbench 2B for expansion is not limited to Figure 1 The table 2 of the cutting plotter 1 can be expanded in the X direction according to the size of the object T by increasing the total number of connected tables 2B.

[0176] In the following description, when the work tables 2A and 2B are not particularly distinguished, they are simply referred to as the work table 2 .

[0177] like Figure 2 As shown, the work table 2 (2A, 2B) has a rectangular shape when viewed from above.

[0178] like Figure 3 As shown, the workbench 2 includes a workbench base 20 with an open upper surface and a workbench table top 21 that blocks the opening of the workbench base 20 .

[0179] The table base 20 has a bottom wall 201 and a peripheral wall 202 surrounding the outer periphery of the bottom wall 201. In the table 2, when the opening of the table base 20 is closed by the table top 21, an internal space 23 is formed between the table base 20 and the table top 21.

[0180] The upper surface of the table surface 21 serves as a placement surface 21 a on which the object T to be processed is placed.

[0181] The object T to be processed is corrugated cardboard, a medium on which information such as text or patterns is printed, a medium made of resin such as acrylic, a paper container, a profile for a billboard, or the like.

[0182] like Figure 4 and Figure 5 As shown, a plurality of suction holes 210 (communication holes) are provided on substantially the entire surface of the placement surface 21 a . The internal space 23 of the workbench 2 communicates with the outside through the suction holes 210 provided on the workbench surface 21 .

[0183] like Figure 4 As shown, a connection port 201a is provided on the bottom wall portion 201 of the table base 20. A connector 32 connected to an end portion of a pipe 31 is fixedly fitted into the connection port 201a.

[0184] The connector 32 includes a cylindrical base portion 321 and a flange portion 322 surrounding the entire outer periphery of the base portion 321 .

[0185] The flange portion 322 bulges radially outward from the outer periphery of the base portion 321 on the side of the one end portion 321 a .

[0186] The end portion 321 a of the base portion 321 is open, and the end portion 321 a of the base portion 321 is fitted into the pipe 31 outside the bottom wall portion 201 .

[0187] The other end portion 321b of the base portion 321 is closed by a disc-shaped cover 323. Therefore, the base portion 321 has a bottomed cylindrical shape.

[0188] The end portion 321b of the base portion 321 passes through the connection port 201a and is inserted into the internal space 23. The end portion 321b of the base portion 321 faces the table surface 21 in the internal space 23 with a gap in the Z direction therebetween.

[0189] In this state, the connector 32 is arranged such that the flange portion 322 provided on the outer periphery of the base portion 321 abuts against the peripheral edge of the connection port 201a of the bottom wall portion 201. A seal ring S is provided on the portion of the flange portion 322 facing the bottom wall portion 201. The seal ring S closes the gap between the flange portion 322 and the bottom wall portion 201.

[0190] A communication hole 324 (through hole) that allows the inside and outside of the base 321 to communicate with each other is provided in a region of the base 321 located within the internal space 23 .

[0191] When viewed from the side, the communicating hole 324 is along the length direction of the base 321 ( Figure 4 (a) is a long hole in the up and down direction).

[0192] like Figure 4 As shown in (b), when viewed from the opening direction of the connection port 201a, a plurality of communication holes 324 are provided at intervals in the circumferential direction around the central axis X321 of the base 321. In this embodiment, four communication holes 324 are provided at 90° intervals in the circumferential direction around the central axis X321.

[0193] like Figure 3 As shown in FIG. 3 , a switching valve 33 is provided on the pipe 31 connected to the connector 32. Figure 3 In FIG. 1 , two connectors 32 and 32 are connected to a pipe 35 provided with a fan 34 via a single switching valve 33 .

[0194] When the fan 34 is driven, a flow of air is formed from one side to the other side of the fan 34. In this embodiment, the fan 34 forms a flow of air from the internal space 23 of the workbench 2 toward the fan 34 inside the piping 31, thereby generating a pressure state (negative pressure state) lower than atmospheric pressure in the internal space 23.

[0195] Then, air is sucked into the internal space 23 from the suction holes 210 opened in the placement surface 21a of the table 2. Due to the flow of air, suction force (negative pressure) is generated in the suction holes 210 on the placement surface 21a of the table 2.

[0196] The object T placed on the workbench 2 is adsorbed to the mounting surface 21a of the workbench 2 by the suction force generated by the driving of the fan 34 and is maintained in a state where movement in the horizontal direction (X direction, Y direction) and the vertical direction (Z direction) is restricted.

[0197] like Figure 2 As shown by the hidden lines, in this embodiment, four connectors 32 are provided on one worktable 2. The connection between each connector 32 and the blower 34 is switched by operating a switching valve 33. Therefore, the area on the worktable 2 where negative pressure is generated can be changed according to the size of the workpiece T placed on the worktable 2.

[0198] Here, if Figure 4 As shown, in the connector 32, the other end 321b of the base 321 is closed by a disc-shaped cover 323. The cover 323 is located in the opening direction of one end 321a of the base 321 ( Figure 4The extension of the vertical direction in (a).

[0199] Therefore, when viewed from the vertical line direction, the cover 323 is arranged in a positional relationship that overlaps with the opening of the one end portion 321 a .

[0200] Here, the opening at one end 321a serves as the inlet for air drawn into the pipe 31. When the other end 321b is open, the flow of air drawn into the pipe 31 is greatest along the length of the base 321. Consequently, the suction force generated on the workbench surface 21 is greatest in the area overlapping the connector 32 when viewed in the Z direction, and decreases with distance from this area. In other words, the suction force generated on the workbench surface 21 is uneven.

[0201] In the connector 32 of this embodiment, the other end 321b of the base 321 is sealed by a disc-shaped cover 323. Therefore, air within the internal space 23 flows into the interior of the base 321 through the elongated communication hole 324 opened on the side of the base 321 and is then drawn toward the piping 31. Consequently, when viewed from a vertical line, air is drawn in approximately evenly from the surrounding area of ​​the connector 32 toward the connector 32. Consequently, compared to a case without the cover 323, variations in the suction force generated on the workbench surface 21 are minimized.

[0202] In the cutting plotter 1 , the object T is processed using a tool held by a processing unit 4 described later, while the object T is restricted from moving in the horizontal directions (X and Y directions) and the vertical direction (Z direction) by the suction force generated on the worktable 2 .

[0203] like Figure 2 and Figure 3 As shown, a support beam 3 supporting the machining unit 4 is horizontally arranged above the work table 2. The support beam 3 has a length that crosses the work table 2 in the Y direction.

[0204] A processing unit 4 is mounted on the support beam 3. The processing unit 4 is supported by the support beam 3 so as to be movable in the longitudinal direction (Y direction) of the support beam 3. A drive mechanism 5C including a resin belt V and a motor Ma for moving the belt V is attached to the support beam 3. The processing unit 4 moves forward and backward in the Y direction in response to the drive mechanism.

[0205] like Figure 3 As shown, the support beam 3 has a pair of support columns 39, 39. The support columns 39, 39 are located on both sides of the table 2 in the Y direction and cross the side of the table base 20 toward the lower side in the Z direction.

[0206] The lower ends of the support columns 39 , 39 are respectively connected to the sliders 55 , 55 of the drive mechanism 5 ( 5A, 5B).

[0207] In the cutting plotter 1 , the support beam 3 is moved in the X direction by the drive mechanisms 5A and 5B provided on both sides of the lower side of the table base 20 .

[0208] Here, the basic structure of the drive mechanisms 5A and 5B is the same. Therefore, the structure of the drive mechanism 5B will be described as a representative example below.

[0209] like Figure 5 As shown, the drive mechanism 5B includes a holder 51 , a guide rail 52 , a rack 53 , a slider 55 , and a motor M.

[0210] The holder 51 is a columnar member fixed to the lower portion of the table base 20. When viewed from the X direction, the holder 51 has a width W51 in the Y direction that is substantially the same as that of the peripheral wall portion 202 of the table base 20.

[0211] Figure 6 It is along Figure 5 The cross-sectional view taken along line AA of the drive mechanism 5B is a cross-sectional view showing a main portion of the drive mechanism 5B.

[0212] Figure 7 This is a cross-sectional view of a main part of the cutting plotter 1 related to the connection with the table. Figure 7 (a) means along Figure 2 FIG. 1 is a diagram of a cross section obtained by cutting the table 2A along line BB in FIG. Figure 7 (b) means along Figure 2 FIG. 1 is a diagram of a cross section obtained by cutting the table 2A along line CC in FIG.

[0213] Figure 8 2 is a diagram illustrating the workbench 2. Figure 8 In (a), the state obtained by observing the mutually connected work tables 2A and 2B from the bottom of the installation surface G side is schematically shown. Figure 8 (b) schematically shows a state where connection rails (connection guide rail 52D, connection rack rail 53D) used after the tables 2A and 2B are connected are arranged.

[0214] Figure 9 This is a cross-sectional view of a main part of the cutting plotter 1 related to the connection with the table. Figure 9 (a) is to use along Figure 7 The cross section along the line AA in (a) shows a connection portion between the table 2A and the table 2B. Figure 9 (b) is to use along Figure 7 The cross section along the line BB in (a) shows a connection portion between the table 2A and the table 2B. Figure 9 (c) is to use along Figure 7 The cross section taken along line CC in (a) shows a connection portion between the table 2A and the table 2B.

[0215] like Figure 9 As shown in FIG. 5 ( b ), the holder 51 is formed to have a length L51 in the X direction from one side edge 2 a to the other side edge 2 b of the table 2 .

[0216] like Figure 5 As shown, a guide rail 52 and a rack rail 53 are provided at a distance from each other in the Y direction at the lower portion of the holder 51. The guide rail 52 and the rack rail 53 are substantially rectangular in shape when viewed in section along the Y direction.

[0217] A protrusion 512 that protrudes downward is provided at the lower portion of the holder 51. When viewed from the X direction, side surfaces 512c and 512d of the protrusion 512 are flat surfaces along the vertical direction (Z direction).

[0218] The rack 53 abuts against the inner side of the table 2 ( Figure 5 In this state, the rack 53 is positioned so that the outer peripheral portion with which the gear 57 engages projects to the inner side (left side in the figure) of the retainer 51.

[0219] The fixing rail 54 contacts the rack 53 from the lower side in the Z direction. The rack 53 is fixed to the lower portion of the holder 51 by bolts (not shown) that penetrate the rail 54 and the rack 53 in the vertical direction.

[0220] The guide rail 52 is arranged outside (to the right in the figure) the protruding portion 512 with a gap therebetween. The guide rail 52 is also fixed to the lower portion of the holder 51 by bolts (not shown).

[0221] A concave rail member 56 fixed to the upper surface of the slider 55 engages with the guide rail 52 from the lower side in the Z direction. The rail member 56 engages with the guide rail 52 so as to be movable in the longitudinal direction of the guide rail 52 while being restricted from falling off the guide rail 52.

[0222] The track member 56 is fixed to the upper surface of the plate-shaped slider 55. A connecting post 551 is provided on the outer side (right side in the figure) of the slider 55 when viewed from the track member 56. The post 551 protrudes upward in the Z direction. The post 551 engages with the engaging hole 390 at the lower portion of the support post 39 described above from the Z direction. The support post 39 is connected to the slider 55 while being placed on the slider 55.

[0223] The slider 55 has a length L55 in the Y direction that crosses the bottom of the holder 51 toward the center side (left side in the figure) of the workbench 2. A notch 55c is provided on the top 55a side of the slider 55.

[0224] The shaft SH of the motor M passes through.

[0225] The motor M is fixed to the lower surface of the slider 55 , and the shaft SH extends upward through the notch 55 c . The upper end of the shaft SH is connected to the gear 57 . The gear 57 meshes with the outer periphery of the rack 53 .

[0226] In the cutting plotter 1 , when the gear 57 rotates in accordance with the output rotation of the motor M, the gear 57 moves in the longitudinal direction (X direction) of the rack 53 .

[0227] The motor M connected to the gear 57 is fixed to the slider 55 together with the support column 39 of the support beam 3. Therefore, when the motor M is driven, the support beam 3 supported by the support column 39 moves in a direction determined by the rotation direction of the motor M ( Figure 5 Move in the direction of the paper's depth).

[0228] like Figure 3 As shown, in the cutting plotter 1, drive mechanisms 5A and 5B are provided on both sides of the table 2 in the Y direction. By driving the drive mechanisms 5A and 5B synchronously, the support beam 3 moves in the X direction.

[0229] like Figure 6 (a) and Figure 8 As shown, when the table 2 is viewed from the lower side in the Z direction, the rack 53 , the protruding portion 512 of the holder 51 , and the guide rail 52 are aligned in the Y direction.

[0230] The guide rail 52 and the rack rail 53 are provided in a range in the X direction (vertical direction in the figure) from the side edge 2 a at one end to the side edge 2 b at the other end of the table 2 (table base 20 ).

[0231] The guide rail 52 includes attaching and detaching guide rails 52A and 52B (attachment and detachment rails) provided on the side edges 2a and 2b, and a fixed guide rail 52C (fixed rail) located between the attaching and detaching guide rails 52A and 52B.

[0232] The guide rail 52 is configured by connecting an attaching and detaching guide rail 52A, a fixed guide rail 52C, and an attaching and detaching guide rail 52B in series.

[0233] The detachable rails 52A and 52B are attached to the table base 20 by bolts (not shown). The detachable rails 52A and 52B are detachable rails that are presupposed to be detached from the table base 20 when the tables 2A and 2B are coupled to each other.

[0234] The fixed guide rail 52C is fixed to the table base 20 by bolts (not shown). The fixed guide rail 52C is a guide rail that is also fixed to the table base 20 when the tables 2A and 2B are connected to each other.

[0235] The rack rail 53 includes detachable rack rails 53A and 53B (detachable rails) provided on the side edges 2 a and 2 b , and a fixed rack rail 53C (fixed rail) located between the detachable rack rails 53A and 53B.

[0236] The rack rail 53 is configured by connecting a detachable rack rail 53A, a fixed rack rail 53C, and a detachable rack rail 53B in series.

[0237] The detachable racks 53A and 53B are attached to the table base 20 by bolts (not shown). The detachable racks 53A and 53B are detachable racks that are designed to be detached from the table base 20 when the tables 2A and 2B are connected to each other.

[0238] The fixed rack rail 53C is fixed to the table base 20 by bolts (not shown). The fixed rack rail 53C is a rack rail that is also fixed to the table base 20 when the tables 2A and 2B are connected to each other.

[0239] Therefore, if Figure 6 As shown in (a), on the side edge 2b of the table 2A, the end 53b of the fixed rack rail 53C is located at a position offset in the X direction by a length L53 from the side edge 2b of the table 2A (table base 20). Furthermore, the end 52b of the fixed guide rail 52C is located at a position offset in the X direction by a length L52 from the side edge 2b of the table 2A.

[0240] On the side edge 2a side of the table 2B, the end 53a of the fixed rack rail 53C and the end 52a of the fixed guide rail 52C are provided at positions offset from the side edge 2a of the table 2B in the X direction by lengths L53 and L52, respectively.

[0241] Similarly, on the side edge 2b of the table 2B, the end 53b of the fixed rack rail 53C and the end 52b of the fixed guide rail 52C are provided at positions offset from the side edge 2b of the table 2B in the X direction by lengths L53 and L52, respectively (see FIG. Figure 9 (a) Figure 9 (c)).

[0242] like Figure 6 As shown in (a), a protrusion 510 is provided on the side edge 2a of the workbench 2B. The protrusion 510 is a cylindrical portion with a spherical surface processed on the top side. The protrusion 510 is freely attachable and detachable relative to the mounting portion 513 of the retainer 51 (see Figure 9 (b)). Although not shown in the figure, a mounting portion 513 is also provided on the side edge 2a of the workbench 2A.

[0243] When viewed from the Z direction, the protrusion 510 extends in the X direction on an extension line of the protruding portion 512 of the holder 51 .

[0244] The side edge 2b of the table 2A is provided with an engagement hole 511. The engagement hole 511 is a cylindrical bottomed hole into which the protrusion can be inserted. When viewed from the Z direction, the engagement hole 511 extends away from the side edge 2b along the protrusion 512 of the holder 51.

[0245] The protrusion 510 of the table 2B is inserted into the engagement hole 511 on the table 2A side from the X direction when the table 2A and the table 2B are connected.

[0246] like Figure 9 As shown in (b), the side edge 2b of the workbench 2B is also provided with an engagement hole 511 of the same structure. When another workbench 2B is further connected to the workbench 2B connected to the workbench 2A, the protrusion 510 on the other workbench 2B side is inserted into the engagement hole 511 of the workbench 2B.

[0247] As described above, the work table 2 has holders 51 attached to the lower portion on both sides in the Y direction. Therefore, the protrusions 510 of the work table 2B are provided on each of the holders 51 located on both sides in the Y direction. Similarly, the engaging holes 511 are also provided on each of the holders 51.

[0248] Here, in this embodiment, one of the two engagement holes 511 arranged in the Y direction is formed into a circular cross section having an inner diameter Da that matches the outer diameter of the protrusion 510 (see FIG. Figure 7 (a) The other engagement hole 511A has the same inner diameter Da in the Z direction as the engagement hole 511 , but has an inner diameter Db in the Y direction that is larger than the inner diameter D of the engagement hole 511 .

[0249] When viewed from the X direction, the engagement hole 511A has an elongated hole shape in which the length in the Y direction is longer than the length in the Z direction.

[0250] like Figure 2 As shown in FIG. 1 , the table 2 has four legs 24 that support the table 2 from below. The four legs 24 are spaced apart from each other in the X and Y directions. The legs 24 are arranged at positions separated from the side edges 2c and 2d of the table 2 toward the center of the table 2 to avoid interference with the gears 57 of the drive mechanism 5 (5A, 5B) (see FIG. 1 ). Figure 3 ).

[0251] Y direction ( Figure 3The leg portion 24 on one side (in the left-right direction in the Y direction) and the leg portion 24 on the other side are connected by a frame 26 extending in the Y direction. The frame 26 is provided in a position spaced upward from the installation surface G of the workbench 2 in a direction along the horizontal line.

[0252] And, as Figure 2 As shown, the legs 24, 24 on the side edge 2c and the legs 24, 24 on the side edge 2d are connected to each other by frames 25, 25 extending in the X direction. The frames 25, 25 are also provided in a horizontal direction at a position spaced upward from the installation surface G of the workbench 2.

[0253] In addition, in this embodiment, a side cover 30 is provided across the leg portions 24, 24 on the side of the side edge 2d (see Figure 3 The side covers 30 are provided to close the openings between the legs 24, 24, the frame 25, and the table base 20 on the side of the side edge 2d, thereby increasing the support strength of the table 2. The side covers 30 serve as a sway suppression member to suppress swaying of the table 2, particularly swaying in the X direction.

[0254] The frame 29 is connected to the middle portion of the frame 26 in the Y direction. Figure 2 As shown, the frame 29 is provided across the frame 26 on the side edge 2a of the table and the frame 26 on the side edge 2b. The frame 26 is arranged in parallel with the frames 25, 25.

[0255] Furthermore, diagonal braces 28, 28 (see FIG. Figure 3 The diagonal braces 28, 28 are inclined in a direction that approaches the table base 20 as they move away from the leg portion 24. The upper ends of the diagonal braces 28, 28 are connected to the connecting portion 27, which is attached to the lower surface of the table base 20. The diagonal braces 28, 28 are arranged in a symmetrical position relative to the connecting portion 27.

[0256] like Figure 2 As shown, diagonal braces 28, 28 and connecting portion 27 are respectively provided on the side edge 2a and side edge 2b of the work table 2. The diagonal braces 28, 28 and connecting portion 27 are provided to suppress vibration of the work table 2 in the longitudinal direction (Y direction) of the support beam 3 and are provided as a shake suppression member to suppress the shaking of the work table 2 in the Y direction.

[0257] The machining unit 4 supported by the support beam 3 moves faster than the carriage in the inkjet printer. When the tool supported by the machining unit 4 machines the object, vibration caused by the displacement of the machining unit 4 acts on the table 2.

[0258] Therefore, in the cutting plotter 1, in order to improve the resistance of the worktable 2 to vibrations generated when processing the processing object T, frames 25, 25, 26 are provided spanning the legs 24, 24, a frame 29 connecting the frames 26, 26, diagonal braces 28, 28 spanning the legs 24 and the worktable base 20, and side covers 30 are provided to improve the resistance to vibrations of the processing unit 4.

[0259] In particular, by providing the side covers 30 that are not used in the inkjet printer, it is possible to preferably suppress shaking (vibration) of the cutting plotter 1 accompanying the movement of the processing unit 4 .

[0260] Figure 10 and Figure 11 It is a figure explaining the caster 91 for movement and the stopper 98 for positioning.

[0261] Figure 10 yes Figure 8 Magnified view of area A in (a). Figure 11 This is a perspective view of the caster 91 provided at the lower end of the leg portion 24 as viewed from obliquely below.

[0262] Figure 12 It is a cross-sectional view of the caster 91. Figure 13 It is a cross-sectional view of the stopper 98 .

[0263] Figure 12 Schematically showing the Figure 10 A cross section of the caster 91 is obtained by cutting along the line AA in FIG. Figure 13 Schematically showing the Figure 10 The BB line in the figure cuts the stopper 98 (see Figure 13 ) and the cross section obtained.

[0264] like Figure 12 As shown, a flange portion 241 extending in the horizontal direction is provided at the lower end of the leg portion 24. The support plate 90 is fixed to the lower surface of the flange portion 241 by bolts (not shown). Casters 91 and stoppers 98 are mounted on the support plate 90.

[0265] The wheel 910 of the caster 91 is rotatably supported by a support shaft 912 provided on a fork 911 (first support portion). Both ends of the support shaft 912 are supported by a pair of support plates 911a, 911a provided on the fork 911 (see Figure 10 ) support.

[0266] In this state, the support shaft 912 is installed along the axis XH (horizontal line) parallel to the installation surface G of the table 2. The wheel 910 is rotatable around the axis XH. The axis XH is parallel to the X direction and the Y direction.

[0267] A cylindrical support tube 913 is provided on the upper portion of the fork portion 911. The outer periphery of the support tube 913 is rotatably supported by a holder 914 via a bearing 915. Thus, the fork portion 911 is rotatable about an axis V1 along a vertical line.

[0268] The retainer 914 is fixed to the lower surface of the bottom portion 961 of the bracket 96. The bottom portion 961 has a generally rectangular shape when viewed from above. Both left and right sides of the bottom portion 961 are bent toward the support plate 90 in the figure to form sidewalls 962, 962 extending toward the support plate 90. The sidewalls 962, 962 are arranged parallel to each other.

[0269] A connecting plate 963 is fixed to the upper surface of the bottom portion 961 on the support plate 90 side. A cylindrical boss portion 964 is provided on the connecting plate 963 along the aforementioned axis V1. The boss portion 964 is formed to rise upward from the connecting plate 963 toward the support plate 90 side. The boss portion 964 has threads on its inner circumference.

[0270] The boss portion 964 is provided such that an opening of the boss portion 964 is arranged along the direction of the axis V1.

[0271] One end portion of a rod-shaped shaft member 965 is screwed into the boss portion 964. In this state, the shaft member 965 is connected to the connecting plate 963 and the bracket 96 so as to be non-rotatable relative to the connecting plate 963 and the bracket 96.

[0272] The shaft member 965 has threads 965a along its entire length in the longitudinal direction. The portion of the shaft member 965 on the support plate 90 side extends through a through-hole 901 provided in the support plate 90. Threads 901a are provided on the inner circumference of the through-hole 901. The shaft member 965 having threads 965a and the threads 910a on the support plate 90 side, which serves as the fixed member, form a thread feed mechanism.

[0273] Therefore, when the bracket 96 is gripped and rotated about the axis V1, the bracket 96, the holder 914, the fork 911, and the wheel 910 are integrally displaced in the direction of the axis V1.

[0274] Therefore, the casters 91 attached to the legs 24 of the workbench 2 can be adjusted in the vertical direction (Z direction). Therefore, by adjusting the positions of the casters 91, the height of the workbench 2 (workbench table 21, workbench base 20) can be adjusted.

[0275] In the shaft member 965, a positioning nut 966 is provided between the support plate 90 and the connecting plate 963. After the position adjustment of the caster 91 in the vertical direction (Z direction) is completed, the positioning nut 966 is rotated to abut against the lower surface of the support plate 90, thereby limiting the rotation of the shaft member 965.

[0276] Positioning brackets 97, 97 are attached to the lower surface of the support plate 90. The positioning bracket 97 includes a fixing portion 971 fixed to the lower surface of the support plate 90 by bolts and a connecting portion 972 extending from the fixing portion 971 in a direction away from the support plate 90 along the axis V1.

[0277] The positioning brackets 97 are symmetrically arranged with the shaft member 965 interposed therebetween. The side walls 962, 962 of the bracket 96 are interposed between the connecting portions 972 spaced apart in the horizontal direction (left-right direction in the figure).

[0278] like Figure 11 As shown, a long hole 972a is provided in the direction along the axis V1 in the connection portion 972. A plurality of long holes 972a are provided at intervals in the Y direction.

[0279] The side walls 962, 962 of the bracket 96 are positioned by the screw Na and nut Nb passing through the long hole 972a in a state of being held between the connecting portion 972 and the nut Nb (see Figure 12 ).

[0280] In this embodiment, casters 91 are provided at the four corners of the workbench 2 in a plan view (see FIG. Figure 8 ) Therefore, by adjusting the position of the casters 91, the height and tilt of the workbench 2 can be adjusted.

[0281] like Figure 10 As shown, in the support plate 90 , a stopper 98 is provided at a position adjacent to the aforementioned caster 91 .

[0282] In the table 2 , the stoppers 98 are located on the side edges 2 c and 2 d in the Y direction of the table 2 when viewed from the casters 91 .

[0283] like Figure 13 As shown, the stopper 98 is an integral component having a disc-shaped contact portion 981 and a shaft member 985 connected to the contact portion 981. The stopper 98 is provided along an axis V2 parallel to the aforementioned axis V1.

[0284] The shaft member 985 extends linearly from the center of the contact portion 981 along the axis V2 in a direction away from the contact portion 981. Threads 985b are provided on the outer periphery of the shaft member 985 on the side of the end 985a opposite to the contact portion 981.

[0285] The portion of the shaft member 985 on the side of the end 985a extends through the through-hole 902 provided in the support plate 90. Threads 902a are provided on the inner circumference of the through-hole 902. The shaft member 985 with the threads 985b and the threads 902a on the side of the support plate 90, which serves as the fixed member, constitute a thread feed mechanism. Therefore, when the stopper 98 is grasped and rotated about the axis V2, the stopper 98 displaces in the direction of the axis V2. This displacement direction is a single direction in the direction of the axis V2, determined by the rotation direction of the stopper 98.

[0286] Therefore, the stopper 98 attached to the leg 24 of the table 2 can be adjusted in the vertical direction (Z direction). Therefore, the cutting plotter 1 is positioned by making the stopper 98 abut against the installation surface G of the cutting plotter 1.

[0287] In this embodiment, a resin retainer 99 is interposed between the contact portion 981 of the stopper 98 and the installation surface G. The retainer 99 has a main body 990 that is generally rectangular in plan view. An elastic member 995, such as rubber, is attached to the entire surface of the main body 990 that faces the installation surface G.

[0288] The main body 990 has a recessed portion 991 on its surface facing the support plate 90 , which is recessed toward the installation surface G. The recessed portion 991 is a substantially cylindrical recess having an inner diameter substantially identical to the outer diameter D981 of the contact portion 981 of the stopper 98 .

[0289] In the shaft member 985, a positioning nut 986 is provided between the support plate 90 and the abutment portion 981. After the position of the stopper 98 in the vertical direction (Z direction) is adjusted, the positioning nut 986 is rotated to abut against the lower surface of the support plate 90, thereby restricting the rotation of the shaft member 985.

[0290] Hereinafter, a procedure will be described in which the side edge 2a side of the table 2B is connected to the side edge 2b side of the table 2A.

[0291] (a) Remove the attachment and detachment guide rail 52B and the attachment and detachment rack rail 53B located on the side edge 2b of the table 2A, and the attachment and detachment guide rail 52A and the attachment and detachment rack rail 53A located on the side edge 2a of the table 2B from the table 2 (table base 20) (see Figure 8 ).

[0292] (b) The stoppers 98 at the four corners of the table 2B are positioned away from the installation surface G, so that the table 2B can be moved.

[0293] (c) The height positions of the casters 91 at the four corners of the workbench 2B are adjusted to align the height of the workbench 2B with the height of the workbench 2A, and to level the workbench surface 21 of the workbench 2B.

[0294] (d) The protrusion 510 on the table 2B side and the engaging holes 511 and 511A on the table 2A side (see Figure 6 、 Figure 7 ) Position the workbench 2B in a relative configuration in the X direction.

[0295] (e) Move the table 2B closer to the table 2A from the X direction, and insert the protrusions 510, 510 on the table 2B side into the engagement holes 511, 511A on the table 2A side (see Figure 7 ).

[0296] At this time, the protrusion 510 having an outer diameter matching the inner diameter of the engagement hole 511 is inserted into one engagement hole 511 , thereby positioning the connected work table 2B in the Y direction with reference to the side surface of the work table 2A where the engagement hole 511 is provided.

[0297] Furthermore, since the inner diameters of the engagement holes 511 and 511A in the Z direction are the same, positional accuracy in the Z direction can be ensured.

[0298] Here, the connection mechanism 500 of the invention is constituted by a protrusion 510 provided on one of the tables 2 to be connected and an engaging hole 511 provided on the other table 2 .

[0299] like Figure 6 As shown in (b), when the table 2B is connected to the table 2A, the fixed guide rail 52C and the fixed rack rail 53C of the table 2A face the fixed guide rail 52C and the fixed rack rail 53C of the table 2B with a gap in the X direction.

[0300] The cutting plotter 1 includes a connecting guide rail 52D that closes a gap between adjacent fixed guide rails 52C and 52C of a table, and a connecting rack rail 53D that closes a gap between adjacent fixed rack rails 53C and 53C.

[0301] (f) Figure 6 (b) Figure 6 (c) and Figure 8 As shown in (b), after the table 2B is connected to the table 2A, the connecting guide rail 52D and the connecting rack rail 53D are arranged across the tables 2A and 2B, thereby forming a guide rail and rack rail that are continuous across the tables 2A and 2B.

[0302] Therefore, the gear 57 (refer to Figure 6) can move between the workbench 2A and the workbench 2B, so the support beam 3 supporting the processing unit 4 can also move between the workbench 2A and the workbench 2B.

[0303] (g) The stoppers 98 at the four corners of the table 2B are positioned so as to come into pressure contact with the installation surface G, thereby fixing the table 2B.

[0304] In this way, the work tables 2A and 2B are connected by inserting the protrusions 510, 510 of the other work table 2B into the engaging holes 511, 511A (recesses) of one work table 2A. The provision of casters 91 for movement facilitates the movement of the work table 2B, shortening the time required to connect the work tables 2A and 2B.

[0305] Therefore, even if the total number of connected work tables 2 increases, the time required to connect the work tables 2 does not increase significantly, and thus the total number of work tables can be easily increased.

[0306] like Figure 1 As shown in FIG. 2 ( b ), the machining unit 4 includes a main body 41 placed on the support beam 3 .

[0307] A fixing unit 42 and a holding unit 43 having three slots 44 ( 44 a to 44 c ) are provided on one side of the main body 41 (the control panel 11 side).

[0308] The fixing unit 42 and the holding unit 43 are adjacent to each other in the Y direction. The upper surface 43 a of the holding unit 43 is located below the fixing unit 42 in the Z direction.

[0309] In the holding unit 43 , the slots 44 a to 44 c are provided so as to be offset toward the fixing unit 42 , and the slots 44 a to 44 c are aligned in the Y direction.

[0310] Figure 14 It is a diagram for explaining the fixing unit 42 . Figure 14 (a) is an enlarged perspective view showing the vicinity of the jig 40 for attaching the pen holder 6 of the fixing unit 42 . Figure 14 (b) is a perspective view showing a state where the pen holder 6 is attached to the jig 40 .

[0311] Figure 15 It is a diagram for explaining the pen holder 6 . Figure 15 (a) is a perspective view of the pen holder 6 as viewed obliquely from below. Figure 15 (b) is a cross-sectional view of the pen holder 6 .

[0312] like Figure 1As shown in (b), the area of ​​the fixing unit 42 on the holding unit 43 side bulges in the X direction. A camera storage section 421 is attached to the lower part of this bulging area. The camera unit (not shown) is stored in the camera storage section 421 in a state facing downward in the Z direction.

[0313] A support unit 422 for supporting the jig 40 is provided beside the camera storage portion 421. The jig 40 is a jig for attaching the pen holder 6 described later.

[0314] like Figure 14 As shown, the clamp 40 has an annular mounting portion 401 and a positioning screw 402. The mounting portion 401 is fixed to the front surface of the plate-shaped base 400. The mounting portion 401 is arranged so that the opening of the mounting portion 401 faces the Z direction. A retaining member 403 for the screw 402 is mounted on the front surface of the mounting portion 401. The shaft of the screw 402 (not shown) passes through the retaining member 403 and the mounting portion 401. The top end of the shaft of the screw 402 can protrude and retract relative to the inner periphery of the mounting portion 401 in conjunction with the rotation operation of the screw 402.

[0315] The cylindrical base 61 of the pen holder 6 is inserted into the mounting portion 401 from the upper side in the Z direction. In this state, the pen holder 6 is fixed to the mounting portion 401 by pressing the tip of the shank of the screw 402 against the outer periphery of the base 61 .

[0316] [Pen holder]

[0317] like Figure 15 As shown, the pen holder 6 is a holder for holding a writing instrument such as a drawing pen. The pen holder 6 includes a cylindrical base 61, a support portion 62 for supporting the pen P, a lock nut 63, and a cap 65.

[0318] The base portion 61 has a cylindrical peripheral wall portion 610. The peripheral wall portion 610 has an outer diameter D61 that matches the inner diameter of the aforementioned mounting portion 401.

[0319] An annular support portion 611 is provided on the inner periphery of the peripheral wall portion 610 at one longitudinal end 610a thereof. A plate 612 made of a magnetic material such as iron is attached to the support portion 611 facing the cover 65.

[0320] The cylindrical fitting portion 653 of the cap 65 is fitted into the end portion 610a of the pen holder 6 from the central axis C6 of the pen holder 6. A magnet 654 is provided at the end of the fitting portion 653. A plurality of magnets 654 are provided at predetermined intervals in the circumferential direction around the central axis C6.

[0321] The cover 65 is formed into a bottomed cylindrical shape by a bottom wall portion 651 and a cylindrical peripheral wall portion 652 surrounding the outer periphery of the bottom wall portion 651. The top end of the peripheral wall portion 652 forms a fitting portion 653 that fits within the base portion 61. The fitting portion 653 is formed to have an outer diameter larger than the outer diameter D652 of the peripheral wall portion 652.

[0322] A flange portion 655 is provided on the outer periphery of the fitting portion 653. The flange portion 655 protrudes radially outward from the outer periphery of the peripheral wall portion 652. The flange portion 655 is provided over the entire circumference around the central axis C6.

[0323] When the cap 65 is attached to the base 61 of the pen holder 6, the end 610a of the base 61 abuts against the flange 655 from the direction of the central axis C6. Furthermore, the magnet 654 provided in the fitting portion 653 is magnetically attracted to the plate 612 on the base 61 side, thereby maintaining the cap 65 magnetically attracted to the base 61.

[0324] In the base portion 61, on the other end portion 610b side of the peripheral wall portion 610 ( Figure 15 A snap-fitting portion 613 is provided on the upper side of the peripheral wall portion 610 (see FIG. 2 ). The snap-fitting portion 613 is formed to bulge out from the inner circumference of the peripheral wall portion 610 toward the inner diameter. The snap-fitting portion 613 has a uniform thickness throughout the entire circumference of the central axis C6 of the pen holder 6. A threaded groove 613a is provided on the inner circumference of the snap-fitting portion 613. The threaded groove 613a of the snap-fitting portion 613 is threadedly engaged with the threaded groove 621c on the support portion 62.

[0325] The support portion 62 includes a barrel portion 621, a centering portion 622, and a screw support portion 624. The barrel portion 621 is a cylindrical portion having an inner diameter D621 that allows insertion of a pen P. A threaded groove 621c is provided along the entire length of the outer circumference of the barrel portion 621 in the longitudinal direction (direction of the central axis C6).

[0326] The centering portion 622 is connected to one end portion 621 a of the cylindrical portion 621 in the direction of the central axis C6 .

[0327] The centering portion 622 is formed into a tapered shape, with the inner diameter D622 decreasing as it moves away from the cylindrical portion 621. A bottom wall portion 623 is provided at the lower end of the centering portion 622. The bottom wall portion 623 is arranged perpendicular to the central axis C6 of the pen holder 6. A through hole 623a having an inner diameter capable of allowing the pen P to pass through is formed in the bottom wall portion 623.

[0328] The through hole 623a is formed with an inner diameter D633 that matches the outer diameter of the pen P. The through hole 623a penetrates the bottom wall portion 623 in the Z direction (vertical direction in the figure) at a position concentric with the central axis C6 of the pen holder 6 .

[0329] When the pen tip P1 of the pen P is inserted into the through hole 623a, the pen tip P1 is positioned on the central axis C6 of the pen holder 6. The inclination of the centering portion 622 relative to the central axis C6 is provided to facilitate guiding the pen tip P1 into the through hole 623a.

[0330] Furthermore, the support portion 62 of the pen holder 6 can be modified depending on the type of pen P being used. In this case, a plurality of support portions 62 having through-holes 623a with different opening diameters can be prepared, and the support portion 62 having through-holes 623a with an appropriate opening diameter can be selected according to the type of pen P. Compared to preparing a complete pen holder 6 for each type of pen P, this can be expected to reduce costs.

[0331] A screw support 624 is connected to the other end 621b of the cylindrical portion 621. The screw support 624 is a cylindrical portion that surrounds the central axis C6 throughout its entire circumference. The screw support 624 has an outer diameter D624 larger than that of the cylindrical portion 621. The screw support 624 is concentrically arranged with the cylindrical portion 621.

[0332] Positioning screws N are provided at predetermined intervals in the screw support portion 624 in the circumferential direction around the central axis C6. The shank N1 of the screw N penetrates the screw support portion 624 in the thickness direction (radial direction of the central axis C6). The tip of the shank N1 engages with a pressing piece 625 disposed inside the screw support portion 624.

[0333] In this embodiment, three screws N are arranged at predetermined intervals in the circumferential direction around the central axis C6. When the screw N is rotated, the pressing piece 625 moves forward and backward in the axial direction of the shaft N1 of the screw N.

[0334] In the pen holder 6 , the pen P is inserted into the cylinder 621 from the screw support 624 . The pen tip P1 of the pen P is fitted into the through hole 623 a of the bottom wall 623 , and the pen P is arranged concentrically with the central axis C6 .

[0335] Here, the pressing piece 625 and the screw N are provided to hold the pen P in a direction along the central axis C6. With the pen tip P1 positioned on the central axis C6, the outer periphery of the base end of the pen P abuts against the pressing piece 625 for positioning, thereby allowing the pen P to be positioned along the central axis C6 over its entire length.

[0336] The engaging portion 613 of the base portion 61 and the lock nut 63 are screwed into the threaded groove 621 c on the outer periphery of the cylindrical portion 621 .

[0337] The support portion 62 including the cylindrical portion 621 , the base portion 61 , and the lock nut 63 are relatively rotatable around the central axis C6 .

[0338] Therefore, when the support portion 62 having the cylindrical portion 621 is rotated relative to the base portion 61 about the central axis C6, the support portion 62 and the base portion 61 are relatively displaced in the direction of the central axis C6. Therefore, by rotating the support portion 62 relative to the base portion 61, the amount (height h) of protrusion of the pen tip P1 of the pen P from the end portion 610a of the peripheral wall portion 610 on the base portion 61 side can be adjusted.

[0339] The lock nut 63 is provided to restrict relative rotation of the support portion 62 with respect to the base portion 61. When the lock nut 63 restricts rotation of the cylindrical portion 621 of the support portion 62, relative displacement of the support portion 62 and the base portion 61 in the direction of the central axis C6 is restricted. The lock nut 63 is provided to maintain the protrusion (height h) of the pen tip P1 of the pen P from the end portion 610a of the peripheral wall portion 610.

[0340] Furthermore, as described above, the cover 65 is attached to the end portion 610 a side of the peripheral wall portion 610 by utilizing the magnetic force of the magnet 654 .

[0341] Here, when the relative rotation direction of the support portion 62 with respect to the base 61 is set to a direction in which the pen tip P1 protrudes from the peripheral wall portion 610 , the cover 65 is slightly separated from the peripheral wall portion 610 when the pen tip P1 exceeds a predetermined height h from the end 610a of the peripheral wall portion 610 .

[0342] In this embodiment, the positional relationship between the fitting portion 653 (magnet 654) of the cap 65 and the bottom wall portion 651 in the direction of the central axis C6 is set so that the cap 65 is separated from the peripheral wall portion 610 when the pen tip P1 reaches a position where the pen tip P1 protrudes by a height h from the end portion 610a of the peripheral wall portion 610. Therefore, the protruding height of the pen tip P1 can be adjusted visually in addition to actual measurement.

[0343] Figure 16 It is a diagram for explaining an example of use of the slots 44a to 44c of the machining unit 4.

[0344] like Figure 1 As shown in FIG. 2( b ), in the holding unit 43 of the machining unit 4 , unused slots 44 a to 44 c are arranged in the Y direction.

[0345] like Figure 16 As shown, the tool support unit 7 is removable relative to the slots 44a to 44c. Figure 16 In FIG. 4 , the support unit 7A is mounted on the slot 44 a. The support unit 7B is mounted on the slot 44 b at a position separated from the machining unit 4 .

[0346] The support unit 7B has an insertion leg 72 that is inserted into the slot 44b. The insertion leg 72 extends downward from the lower portion of the main body 71. The main body 71 houses a drive mechanism such as a motor for driving the tool.

[0347] The support unit 7 is attached to the holding unit 43 by inserting the insertion legs 72 into the slots 44 , and a driving mechanism inside the main body 71 is connected to a power supply source.

[0348] The main body 71 has a range in the Z direction that reaches the front side of the insertion leg 72. The tool holder 74 is supported by a support member 73 at the lower portion of the main body 71.

[0349] The tool holder 74 is provided on the front side of the main body 71 in the direction along the Z direction. The tool 8 is mounted on the lower portion of the tool holder 74.

[0350] The tool 8 has a connecting portion 81 at a portion facing the lower portion of the tool holder 74. The connecting portion 81 is connected to a shaft (not shown) housed inside the tool holder 74 so as to be non-rotatable relative to the shaft.

[0351] exist Figure 16 In FIG. 7 , a hole machining tool 8 ′ is mounted on the support unit 7A. A tool 8 supporting a cutter 10 is mounted on the support unit 7B.

[0352] The tool 8 has an angle adjustment mechanism 100 for the mounted tool 10 .

[0353] The machining unit 4 has a plurality of slots 44 (44a to 44c) into which tool support units 7 (7A, 7B) are detachably mounted. The tool 8 supported by the support unit 7 holds a tool 8 capable of adjusting the tilt of the held cutter 10.

[0354] The machining unit 4 has multiple slots 44, allowing multiple tools with different uses to be installed in the machining unit 4. This eliminates the need to replace the tool each time the machining method changes, as long as the machining method can be performed using any tool already installed in the machining unit 4. This reduces the time required for tool replacement. Furthermore, by adjusting the positional accuracy of the tool when it is initially installed in the machining unit 4, it eliminates the need to adjust the tool position each time the machining method changes, as long as the machining method can be performed using any tool already installed in the machining unit 4. Therefore, even if the machining method changes, the machining accuracy of the object T can be maintained.

[0355] Figures 17 to 21 It is a diagram for explaining the tool 8. Figure 17 (a) is a diagram showing the tool 8 attached to the tool holder 74 of the support unit 7B as viewed from the front side. Figure 17In (a), only the portion of the tool 8 is indicated by a solid line, and the other portions are indicated by an imaginary line. Figure 17 (b) is a perspective view of the tool 8. Figure 17 (c) is a diagram illustrating the attachment of the tool holder 88 to the mounting plate 82 .

[0356] Figure 18 It is a front view of the mounting plate 82. Figure 19 It is an exploded view of the tool holder 88 . Figure 20 is a rear view of the mounting plate 82. Figure 21 (a) is a diagram illustrating the inclination of the tool 10 when the tool holder 88 is attached to the hole group 84D. Figure 21 (b) is a diagram illustrating the inclination of the tool 10 when the tool holder 88 is attached to the hole group 84A. Figure 21 (c) is a diagram illustrating the inclination of the tool 10 when the tool holder 88 is mounted on the front surface of the mounting plate 82 and the inclination of the tool 10 ′ when the tool holder 88 is mounted on the back surface of the mounting plate.

[0357] like Figure 17 As shown, the tool 8 has a connecting portion 81 connected to the support unit 7B side. A mounting plate 82 is provided below the connecting portion 81. The mounting plate 82 is a plate-shaped member arranged along the Z direction (vertical direction) when the support unit 7B is set on the holding unit 43.

[0358] like Figure 17 As shown in FIG. 8( b ), both side surfaces in the thickness direction of the mounting plate 82 serve as mounting surfaces 82 a and 82 b of the connecting piece 881 on the tool holder 88 side.

[0359] like Figure 18 As shown, when viewed from the mounting surface 82a, the upper side 821 of the mounting plate 82 on the connecting portion 81 side is formed into a substantially straight line. When the connecting portion 81 of the tool 8 is connected to the support unit 7B side, the upper side 821 of the mounting plate 82 is arranged in a direction along the horizontal line.

[0360] The connection part 81 is connected to the substantially longitudinal center part of the upper side 821. The connection part 81 is provided in the direction orthogonal to the upper side 821.

[0361] The side edges 822 and 823 of the mounting plate 82 are perpendicular to the upper edge 821 , and the side edges 822 and 823 extend linearly in a direction away from the connecting portion 81 .

[0362] One side 823 reaches a position farther from the connection portion 81 than the other side 822 .

[0363] The lower side 824 of the mounting plate 82 is formed in an arc shape that is recessed toward the upper side 821. The lower side 824 is formed in an arc shape along an imaginary circle Im1 having the cutting edge 10a of the tool 10 supported by the mounting plate 82 as the center C. This is to avoid interference with the tool holder 88 described later.

[0364] A plurality of hole groups 84 (84A to 84D) consisting of circular holes 841 and elongated holes 842 are provided on one mounting surface 82a. Here, the combination of the circular holes 841 and elongated holes 842 of the hole group 84 corresponds to a pair of engagement points on the mounting surface side of the invention.

[0365] The circular hole 841 and the long hole 842 are bottomed holes that do not penetrate the mounting plate 82 in the thickness direction.

[0366] Each hole group 84 includes a screw hole 85 between the circular hole 841 and the elongated hole 842. The screw holes 85 are through-holes that penetrate the mounting plate 82 in the thickness direction. The screw holes 85 are arranged at intervals in the circumferential direction around an imaginary circle Im4, which has a larger outer diameter than the imaginary circle Im1. The screw holes 85 are used to secure the tool holder 88 to the mounting plate 82.

[0367] The hole group 84 is formed so that the inclination of the blade edge 10a relative to the horizontal line is set to a desired angle and the connecting piece 881 on the tool holder 88 side (see Figure 17 (c)) is a positioning hole used when installed on the mounting surface 82a.

[0368] In the present embodiment, by changing the hole group 84 ( 84A to 84D) used when attaching the tool holder 88 to the mounting plate 82 , the inclination of the blade edge 10 a with respect to the horizontal line HL can be set to a predetermined inclination.

[0369] The circular hole 841 is located closer to the upper side 821 than the elongated hole 842. When viewed from the mounting surface 82a, the circular hole 841 is circumferentially spaced apart at a position where the outer periphery of the lower side 824 of the circular hole 841 is substantially tangent to the outer periphery of the imaginary circle Im2. The elongated hole 842 is circumferentially spaced apart at a position where the outer periphery of the upper side 821 of the circular hole 841 is substantially tangent to the inner periphery of the imaginary circle Im3. The elongated hole 842 is disposed at a position spaced Dx apart from the circular hole 841 toward the lower side 824.

[0370] A plurality of hole groups 84 are provided at intervals in the circumferential direction with the position of the blade edge 10a as the center C. Figure 18 In the embodiment, a total of four hole groups 84 (84A to 84D) are provided on one mounting surface 82a.

[0371] In the case of the hole group 84A, a straight line La connecting the center of the circular hole 841 and the center of the long hole 842 extends along the longitudinal direction of the long hole 842. This straight line La intersects the tool 10 held by the tool holder 88 at a predetermined angle θ.

[0372] The other hole groups 84B, 84C, and 84D are set so that the straight lines Lb, Lc, and Ld connecting the circular hole 841 and the long hole 842 intersect the straight line La at angles θb, θc, and θd.

[0373] In the present embodiment, when the tool holder 88 is attached to the hole group 84A, the angle θ is set so that the tool edge 10 a forms a predetermined angle, for example, 45°, with the horizontal line HL.

[0374] Furthermore, the other hole groups 84B, 84C, and 84D set angles θb, θc, and θd between the respective straight lines Lb, Lc, and Ld and the straight line La so that the blade edge 10a forms a desired angle with the horizontal line HL (Y direction).

[0375] Therefore, when the tool holder 88 is mounted on the mounting plate 82 , the tool 10 can be mounted on the mounting plate 82 while setting the tool tip 10a to the desired inclination by using one hole group 84 determined according to the inclination of the tool tip 10a relative to the horizontal line HL, i.e., the inclination to be set.

[0376] like Figure 19 As shown, the tool holder 88 includes a connecting piece 881 , a support portion 882 that supports one surface of the tool 10 , and a gripping portion 883 that grips the tool 10 between the support portion 882 and the tool holder 881 .

[0377] The support portion 882 and the grip portion 883 have support surfaces 882a and 883a that are parallel to each other, and between these support surfaces 882a and 883a, the plate-shaped base 101 of the tool 10 is gripped. In this state, the tool 10 is supported on the tool holder 88 by passing the rods of a pair of fixing screws N and N (not shown) through the grip portion 883 and the tool 10 and screwing them into the support portion 882.

[0378] like Figure 17 As shown in (c), the support portion 882 and the grip portion 883 have predetermined widths W882 and W883 in the thickness direction of the connecting piece 881, respectively. The support portion 882 is aligned with the support surface 882a (refer to Figure 19 The connecting piece 881 extends from the center of the flat surface 882b in the width direction in a direction away from the support portion 882.

[0379] like Figure 19As shown, through-holes 861 and 862 are provided on the top end 881c of the connecting piece 881. Here, through-holes 861 and 862 correspond to a pair of engagement points on the tool holder 88 of the present invention. Through-holes 861 and 862 are spaced apart on a straight line L88 passing through the center of the width of the connecting piece 881. The distance Dx' between through-holes 861 and 862 is set to be greater than the distance Dx between the circular hole 841 and the elongated hole 842 on the mounting plate 82.

[0380] Specifically, the pin PN (see Figure 17 (c)) is set to a length that can be inserted into the circular hole 841 and the long hole 842.

[0381] A screw hole 87 is provided on one side of the straight line L88 between the through hole 861 and the through hole 862. Figure 19 As shown, when viewed from the mounting direction of the tool holder 88 , a straight line L88 connecting the through holes 861 and 862 intersects the aforementioned support surface 882 a of the tool 10 at a predetermined angle θ.

[0382] In the tool holder 88 , after the tool 10 is gripped between the support portion 882 and the grip portion 883 , any hole group 84 on the mounting plate 82 is selected to attach the connecting piece 811 .

[0383] For example, when the hole group 84A is selected, the through holes 861 and 862 on the connecting piece 811 side are arranged so as to overlap with the circular holes 841 and the long holes 842 of the hole group 84A on the mounting plate 82 side. Figure 17 One of the pair of pins PN shown in (c) is inserted from the through hole 861 and embedded in the circular hole 841, and the other pin PN is inserted from the through hole 862 and embedded in the long hole 842. Then, the tool holder 88 is fixed to the mounting plate 82 on the tool 8 side by screwing the shank N1 of the screw N into the screw hole 87 on the connecting piece 881 side and the screw hole 85 on the mounting plate 82 side (see Figure 17 (b)).

[0384] At this time, the cutting edge 10a of the cutting tool 10 held by the cutting tool holder 88 is arranged at a predetermined angle determined by the hole group 84 for mounting (see FIG. Figure 21 ).

[0385] In the present embodiment, the positional relationship of the hole groups 84 ( 84A to 84D) on the mounting plate 82 side is set so that the cutting edge 10 a of the tool 10 is always arranged at the same position C regardless of which hole group 84 is used.

[0386] Therefore, the operation of adjusting the position of the blade edge 10 a each time the angle of the tool 10 is changed can be omitted or simplified.

[0387] In addition, if Figure 20 As shown, the mounting surface 82b on the opposite side of the mounting plate 82 is also provided with a hole group 84E consisting of a circular hole 841 and a long hole 842. When the tool holder 88 is mounted using this hole group 84E, the tool 10 is set in a direction perpendicular to the horizontal line HL. When viewed from the mounting surface 82b side, the arrangement of the tool 10 at this time becomes Figure 21 The position shown by reference numeral 10' in (c).

[0388] In this manner, by changing the hole group 84 for mounting the tool holder 88 in the mounting plate 82 of the tool 8 , the inclination of the tool 10 with respect to the horizontal line HL can be easily set to one of the predetermined inclinations.

[0389] Here, the angle adjustment mechanism 100 of the tool 10 of the present invention is formed by the hole group 84 (84A to 84E) of the mounting plate 82, the through holes 861 and 862 of the connecting piece 811 of the tool holder 88, and the pair of pins PN. The arrangement of the hole group 84 (84A to 84E) of the mounting plate 82 corresponds to the positioning member of the present invention.

[0390] In the embodiment, the engagement points on the mounting surface side are the circular hole 841 and the long hole 842 , and the engagement points on the tool holder 88 side are the through holes 861 and 862 . These engagement points are connected by the pin PN corresponding to the engagement pin.

[0391] The tool holder 88 may be mounted on the mounting surfaces 82a, 82b while omitting the pin PN by providing one of the engagement points on the mounting surface side and the engagement point on the tool holder 88 side as a protrusion and the other as a recessed hole.

[0392] As described above, the cutting plotter 1 according to the embodiment has the following configuration.

[0393] (1) The cutting plotter 1 is a processing device having:

[0394] a workbench 2 on which a workpiece T is placed;

[0395] a machining unit 4 (supporting portion) that supports a tool for machining the object T and moves along the supporting beam 3; and

[0396] The driving mechanism enables the machining unit 4 to move relative to the workbench.

[0397] The drive mechanism has:

[0398] a drive mechanism 5C (Y-direction drive mechanism) that moves the machining unit 4 in the Y-direction along the support beam; and

[0399] The driving mechanisms 5A and 5B (X-direction driving mechanisms) move the machining unit 4 in the X-direction, which is a direction perpendicular to the Y-direction.

[0400] The table 2 includes legs 24 that support, from below, a table base 20 (a placement portion) having a table surface 21 on which a workpiece T is placed. The legs 24 are provided at intervals in the X and Y directions.

[0401] A shake suppression member (side cover 30, diagonal braces 28, 28, connecting portion 27, frame 25, 26, 29) is provided between any one leg 24 and the other leg 24 or between the leg 24 and the worktable base 20. The shake suppression member (side cover 30, diagonal braces 28, 28, connecting portion 27, frame 25, 26, 29) suppresses the shake of the worktable 2 in both the X direction and the Y direction as the machining unit 4 and the support beam 3 are moved by the driving mechanism.

[0402] According to this structure, it is possible to preferably suppress the shaking of the table 2. Therefore, it is possible to suppress the degree to which the vibration generated when processing the object T affects the processing of the object T, and the object T can be processed more appropriately.

[0403] (2) The stage 2 is formed by connecting at least two stages in the X direction.

[0404] The connecting mechanism 500 that connects the work tables 2 to each other is composed of a protrusion 510 and an engagement hole 511 (recess).

[0405] The protrusion 510 protrudes from one workbench 2B in the X direction.

[0406] The engaging hole 511 (recessed portion) is provided in the other table 2A and is used for fitting the protrusion 510 therein.

[0407] A plurality of connection mechanisms 500 are provided at intervals in the Y direction.

[0408] With this configuration, relative displacement in the Y direction of the connected work tables 2A and 2B is suppressed by the connection mechanism 500. Furthermore, the mass of the work table 2 obtained by connecting the work tables 2A and 2B is greater than the mass of the processing tool and the processing unit 4 that supports the tool. Therefore, the work table 2 is less susceptible to vibration caused by the movement of the processing unit 4, and vibration of the processing object T placed on the work table 2 can be suppressed.

[0409] Therefore, it is possible to suppress the degree to which vibration caused by the movement of the tool affects the accuracy when the tool is moved in the X and Y directions relative to the object T. Therefore, the object T can be processed more appropriately.

[0410] In the cutting plotter 1 (machining device), the displacement speed of the machining unit 4 when displacing the tool in the Y direction is greater than that when displacing the tool in the X direction, and the vibration in the Y direction is greater than that in the X direction.

[0411] As described above, by providing a plurality of connecting mechanisms 500 spaced apart in the Y direction, relative movement and vibration of the connected work tables 2A and 2B in the Y direction can be further suppressed. Therefore, the degree to which vibration caused by the movement of the tool in the Y direction affects the accuracy of relative movement of the tool with respect to the object T can be suppressed, allowing the object T to be processed more appropriately.

[0412] (3) The cutting plotter 1 includes the guide rail 52 for guiding the movement of the support beam 3 in the X direction.

[0413] In the table 2 , the guide rails 52 include fixed guide rails 52C provided along the X direction on both sides in the Y direction and facing the guide rails 52 on the other table 2 to be connected with a gap in the X direction.

[0414] Furthermore, a connecting rail 52D is provided. The connecting rail 52D is inserted between the fixed rails 52C and 52C that are arranged opposite to each other, and connects the fixed rail 52C on one workbench 2 side and the fixed rail 52C on the other workbench 2 side.

[0415] According to this structure, the fixed rails 52C and 52C of the two connected tables 2A and 2B are connected via the connecting rail 52D. Therefore, the rail for guiding the movement of the support beam 3 in the X direction is continuously provided across the two connected tables 2A and 2B.

[0416] This continuous rail restricts the relative displacement of the two connected worktables 2A and 2B, thereby increasing the rigidity of each of the connected worktables 2A and 2B. This reduces the degree to which vibrations caused by tool movement in the Y direction affect the accuracy of relative movement of the tool with respect to the object T.

[0417] In particular, since the fixed rails 52C and 52C are connected to each other laterally of the connection mechanism 500 via the connection rail 52D, the connection rail 52D acts as a barrier to the relative movement of the connected work tables 2A and 2B in the Y direction, with the connection mechanism 500 portion of the work tables 2A and 2B serving as a fulcrum, thereby limiting the relative movement of the work tables 2A and 2B. Consequently, vibration of the work table 2 can be further suppressed.

[0418] (4) The driving mechanism includes the driving mechanism 5 (5A, 5B) (X-direction driving mechanism) for moving the support beam 3 in the X direction.

[0419] The drive mechanisms 5A and 5B include a gear 57 that is rotationally driven by a motor M and a rack 53 with which the gear 57 meshes.

[0420] In the table 2A, the rack 53 includes a fixed rack 53C provided along the X direction and arranged to face the rack 53 on the other table 2B side to which the table is connected with a gap in the X direction.

[0421] The connecting rack 53D is inserted between the fixed racks 53C and 53C that are arranged opposite to each other, and connects the fixed rack 53C on the table 2A side and the fixed rack 53C on the other table 2B side.

[0422] With this structure, the fixed racks 53C and 53C of the two connected tables 2A and 2B are connected via the connecting rack 53D. Therefore, the rack for moving the support beam 3 in the X direction is continuously provided across the two connected tables 2A and 2B.

[0423] This continuous rack restricts the relative displacement of the two connected worktables 2A and 2B, thereby improving the rigidity of the connected worktable 2 as a whole. This reduces the degree to which vibrations caused by tool movement in the Y direction affect the accuracy of relative movement of the tool with respect to the workpiece T.

[0424] (5) In the table 2 , the guide rails 52 and the rack rails 53 are provided on both sides of the connection mechanism 500 (the protrusions 510 and the engaging holes 511 ) in the Y direction.

[0425] According to this structure, the guide rail 52 and the rack rail 53 are arranged on one side and the other side of the connection mechanism 50.

[0426] In the Y direction, the connecting mechanism 50 is located between the guide rail 52 and the rack rail 53 , and the relative displacement of the two connected work tables 2A and 2B to one side in the Y direction and to the other side in the Y direction is restricted by the guide rail 52 and the rack rail 53 .

[0427] Therefore, the vibration of the entire work table 2 obtained by connecting the work tables 2A and 2B can be preferably suppressed.

[0428] (6) In the table 2 , a plurality of suction holes 210 (communication holes) are opened on the placement surface 21 a of the workpiece T so as to communicate between the interior (internal space 23 ) and the exterior of the table 2 .

[0429] The workbench 2 has a connection port 201a (insertion port) for inserting the connector 32 of the blower 34 (negative pressure generating member) on the bottom wall portion 201 (back side) on the side opposite to the placement surface 21a.

[0430] The connector 32 has:

[0431] A bottomed cylindrical base 321, one end 321b of which in the longitudinal direction is closed by a cover 323; and

[0432] The communication hole 324 (through hole) penetrates the base portion 321 in the radial direction, thereby connecting the inside and outside of the base portion 321 .

[0433] One end portion 321 b of the base portion 321 is disposed facing the table surface 21 having the placement surface 21 a in the internal space 23 of the table 2 .

[0434] The communication hole 324 is provided in a region of the base 321 located within the internal space 23 of the workbench 2 .

[0435] The communication hole 324 is a long hole extending along the direction in which the connector 32 is inserted into the connection port 201a. A plurality of communication holes 324 are provided in the base portion 321 at intervals in the circumferential direction.

[0436] With this configuration, when the blower 34 is driven, the air in the internal space 23 of the table 2 is sucked toward the blower 34 via the connector 32 , thereby generating negative pressure in the table 2 .

[0437] Here, the opening at one end 321a of the base 321 serves as the inlet for air drawn into the pipe 31. If the other end 321b is open, the flow of air drawn into the pipe 31 is greatest along the length of the base 321. Consequently, the suction force generated on the workbench surface 21 is greatest in the area overlapping the connector 32 when viewed in the Z direction, and decreases with distance from this area. In other words, the suction force generated on the workbench surface 21 is uneven.

[0438] In contrast, in the connector 32, the other end 321b of the base 321 is sealed by a disc-shaped cover 323. Therefore, air within the internal space 23 flows into the interior of the base 321 through the long, hole-shaped connecting hole 324 opened on the side of the base 321, and is then drawn toward the piping 31. Therefore, when viewed from the vertical line, air is drawn in roughly evenly from the surrounding area of ​​the connector 32 toward the connector 32. Therefore, compared to a case where the cover 323 is not provided, variations in the suction force generated on the workbench surface 21 can be suppressed. Therefore, the object T can be reliably held on the mounting surface 21a, allowing for more appropriate processing of the object T.

[0439] (1) The cutting plotter 1 is a processing device having:

[0440] a tool 8 for processing the processing object T; and

[0441] The driving mechanism 5C causes the tool 8 to reciprocate in the Y direction (one direction).

[0442] The tool 8 holds a cutting tool 10 .

[0443] The tool 8 includes an angle adjustment mechanism 100 capable of adjusting the angle of the tool 10 with respect to the Y direction.

[0444] The angle adjustment mechanism 100 is provided with a group of holes 84 ( 84A to 84E) as positioning members corresponding to a plurality of angles. The group of holes 84 ( 84A to 84E) positions the tool 10 and fixes the tool 10 at the positioned position.

[0445] The positioning member is provided at a position where, when the tool 10 is positioned and fixed, the position of the cutting edge 10 a of the tool 10 is constant regardless of a plurality of angles.

[0446] With this configuration, the position of the tool tip 10a can be always arranged at the same position even if the angle of the tool 10 is changed. Therefore, there is no need to adjust the position of the tool tip 10a every time the angle of the tool 10 is changed, so the processing accuracy of the processing object T can be ensured.

[0447] (II) The blade 10 has a shape extending in a plate shape toward the blade edge 10a.

[0448] The shape between the positioning member and the blade edge 10 a is curved midway in the extending direction of the cutter 10 .

[0449] With this configuration, a positioning member is disposed on one side in the thickness direction of the plate-shaped tool 10. Therefore, when machining the object T, the positioning member can withstand the reaction force acting on the tool tip 10a from the object T side, thereby reducing the load acting on the tool 10.

[0450] (III) Tool 8 has:

[0451] a tool holder 88 that supports the tool 10 ; and

[0452] The mounting plate 82 (mounted member) has a mounting surface 82 a for the tool holder 88 .

[0453] A plurality of hole groups 84 (circular holes 841 and long holes 842 ) corresponding to a pair of engagement points are set on the mounting surface 82 a .

[0454] When the tool holder 88 is mounted on the mounting surface 82 a using the selected hole group 84 , the tool 10 held by the tool holder 88 is arranged at an angle determined by the selected hole group 84 .

[0455] If constructed in this manner, a hole group 84 that enables the angle of the tool 10 to be set to the desired angle is selected from a plurality of hole groups 84 (circular holes 841, long holes 842) located on the mounting surface 82a, which are equivalent to a pair of engagement points. The tool holder 88 is mounted on the mounting surface 82a of the mounting plate 82 using the selected hole group 84, thereby enabling the tool 10 to be configured at the desired angle.

[0456] Therefore, the angle of the tool is determined according to the selected hole group 84, so the tool 10 can be accurately positioned at a desired angle simply by selecting the hole group 84. Therefore, a decrease in machining accuracy caused by contact of the tool 10 at an angle can be preferably prevented.

[0457] (IV) When viewed from the mounting direction of the tool holder 88 toward the mounting surface 82a,

[0458] The hole group 84 corresponding to a pair of engagement points is composed of a circular hole 841 (first engagement point) and a long hole 842 (second engagement point).

[0459] The circular hole 841 (first engagement point) is located on an imaginary circle Im2 (first imaginary circle) having the cutting edge 10a of the tool 10 supported by the tool holder 88 mounted on the mounting surface 82a as its center C.

[0460] The above-mentioned long hole 842 (second engaging point) is located on the imaginary circle Im3 (second imaginary circle), the diameter of which is smaller than that of the imaginary circle Im2 and is concentric with the imaginary circle Im2.

[0461] In the mounting surface 82a, a plurality of hole groups 84 (84A to 84D) are provided with their phases shifted in the circumferential direction of the imaginary circle Im2.

[0462] With this configuration, the position of the tool tip 10a can be always arranged at the same position even if the selected hole group 84 is changed. Therefore, there is no need to adjust the position of the tool every time the processing method is changed, so the processing accuracy of the processing object can be ensured even if the processing method is changed.

[0463] (V) The tool holder 88 has through holes 861 and 862 serving as a pair of engagement points in a portion facing the mounting surface 82 a .

[0464] The tool holder 88 is mounted on the mounting surface 82a so that the through holes 861 and 862 corresponding to the pair of engagement points on the tool holder 88 side match the holes (circular hole 841 and long hole 842) of the hole group 84 selected on the mounting surface 82a.

[0465] If constructed in this way, by pre-setting the intersection angle between the straight lines Lb~Ld connecting the holes (circular holes 841, long holes 842) of each hole group 84B~84D and the straight line La connecting the holes (circular holes 841, long holes 842) of the hole group 84A, the tool 10 can be configured at an angle determined according to the selected hole group 84.

[0466] Furthermore, the position of the tool tip 10a can be always arranged at the same position even if the selected hole group 84 is changed. Therefore, there is no need to adjust the position of the tool every time the processing method is changed, so the processing accuracy of the processing object can be maintained even if the processing method is changed.

[0467] (VI) The mounting plate 82 (mounted member) is a plate-shaped member having mounting surfaces 82 a and 82 b on both sides in the thickness direction.

[0468] According to this structure, the mounted member has two mounting surfaces 82a and 82b, and the degree of freedom in setting the inclination of the tool mounted on the mounting plate 82 via the tool holder 88 is improved.

[0469] (VII) In the mounting plate 82 (mounted component), the tool holder 88 is positioned using the pins PN, PN (engagement pins) of the hole group 84 (84A to 84E) that spans the engagement points on the mounting surfaces 82a and 82b and the through holes 861 and 862 that span the engagement points on the tool holder 88.

[0470] If constructed in this way, the tool holder 88 on the mounting plate 82 can be easily positioned simply by arranging pins PN and PN across the holes (circular holes 841 and long holes 842) of the hole group 84 corresponding to the engagement points on the mounting surfaces 82a and 82b and the through holes 861 and 862 (holes) provided on the tool holder 88 side.

[0471] (VIII) The processing unit 4 (support portion) includes a jig 40 that supports the pen holder 6 .

[0472] The pen holder 6 includes a support portion 62 that supports the pen P, a cylindrical base portion 61 to which the support portion 62 is screwed so as to be relatively rotatable, and a cap 65 that closes an opening on the end portion 610 a side of the base portion 61 .

[0473] In the cover 65 , the fitting portion 653 fitted into the end portion 610 a of the base 61 is held by the magnetic force of a magnet 654 provided in the fitting portion 653 on the plate 612 provided in the support portion 611 on the base 61 side.

[0474] When the support portion 62 rotates relative to the base portion 61 , the pen tip P1 is displaced in a direction determined by the rotation direction of the support portion 62 .

[0475] The support portion 62 includes a centering portion 622 that guides the pen tip P1 of the pen P supported by the support portion 62 to the center of the base 61 .

[0476] The positional relationship between the interlocking portion 653 (magnet 654) of the cover 65 and the center axis C6 direction of the plate 612 is set so that when the pen tip P1 reaches the position where the pen tip P1 protrudes from the end 610a of the peripheral wall portion 610 by a height h, the cover 65 separates from the peripheral wall portion 610.

[0477] With this configuration, the protruding height of the pen tip P1 can be adjusted visually in addition to actual measurement.

[0478] (7) The workbench 2 (2A, 2B) is a workbench for the cutting plotter 1 (processing device), which has:

[0479] a machining unit 4 (supporting portion) that supports a tool for machining the object T and moves along the supporting beam 3;

[0480] a drive mechanism 5C (Y-direction drive mechanism) that moves the machining unit 4 in the Y-direction along the support beam 3 ; and

[0481] The driving mechanisms 5A and 5B (X-direction driving mechanisms) move the machining unit 4 in the X-direction, which is a direction perpendicular to the Y-direction.

[0482] The table 2 is formed by connecting at least two tables 2A and 2B (common table) in the X direction.

[0483] Workbench 2 has:

[0484] a table surface 21 on which a workpiece T is placed;

[0485] a workbench base 20 supporting a workbench surface 21; and

[0486] A plurality of legs 24 support the workbench base.

[0487] A mounting portion 513 for a protrusion 510 is provided on a side edge 2a at one end in the X direction (first direction) of the table base 20. Engaging holes 511, 511A (recesses) into which the protrusion 510 can be fitted from the X direction are provided on a side edge 2b at the other end of the table base 20.

[0488] The leg portion 24 has casters 91 for movement and stoppers 98 for positioning.

[0489] With this structure, the work platforms 2A and 2B are connected by inserting the protrusions 510 and 510 of one work platform 2B into the engaging holes 511 and 511A (recesses) of the other work platform 2A. The provision of casters 91 for movement facilitates movement of the work platform 2, shortening the time required to connect the work platforms 2A and 2B.

[0490] Therefore, even if the total number of connected work tables 2 increases, the time required to connect the work tables 2 does not increase significantly, and thus the total number of work tables can be easily increased.

[0491] (8) The leg portion 24 is provided on one side of the side edge 2c and on the other side of the side edge 2d in the Y direction (the second direction) at one end side (the side edge 2a side) and at the other end side (the side edge 2b side) in the X direction (the first direction) of the workbench 2 (the workbench base 20), respectively.

[0492] In the Y direction, the stopper 98 is located closer to the side edges 2 c and 2 d than the caster 91 .

[0493] According to this structure, since the tables are connected in the X direction, the connected tables 2 can be approached from the Y direction (side edges 2c and 2d).

[0494] Therefore, by positioning the stopper 98 closer to the side edges 2c and 2d than the casters 91, access to the stopper 98 is facilitated after the workbenches 2 are coupled together. Furthermore, the casters 91 do not obstruct access to the stopper 98. Therefore, after the workbenches 2 are coupled together, the stopper 98 can be quickly brought into pressure contact with the installation surface G, thereby positioning the workbenches 2.

[0495] (9) The casters 91 and the stoppers 98 are provided so that their positions can be adjusted in the vertical direction with reference to the installation state of the workbench 2 .

[0496] When connecting the work tables 2 , 2 to each other, it is necessary to make the newly connected work table 2 level and align the height of the newly connected work table with the height of the connection target.

[0497] According to the above-described configuration, the height and inclination of the table 2 can be easily adjusted, and thus the time required for coupling the tables 2 to each other can be shortened.

[0498] (i) Caster 91 has:

[0499] Wheel 910;

[0500] a fork 911 (first supporting portion) that supports the wheel 910 so as to be rotatable about an axis XH along a horizontal line; and

[0501] The holder 914 (second supporting portion) supports the fork portion 911 so as to be rotatable around an axis V1 extending along the vertical direction.

[0502] The first position adjustment mechanism that supports the holder 914 of the caster 91 so as to be positionally adjustable in the direction of the axis V1 on the support plate 90 fixed to the leg portion 24 includes:

[0503] The shaft member 965 (first shaft member) passes through the through hole 901 provided in the support plate 90 in the direction of the axis V1, and has the threads 965a provided on the outer periphery screwed into the threads 901a on the inner periphery of the through hole 901;

[0504] a bracket 96 that connects the shaft member 965 and the caster 91 and is supported on the support plate 90 via a positioning bracket 97; and

[0505] The positioning nut 966 is threadedly coupled to the shaft member 965 .

[0506] The screw thread 901 a of the through hole 901 of the support plate 90 (fixed-side member) and the screw thread 965 a of the shaft member 965 connected to the caster 91 constitute a screw feeding mechanism.

[0507] With the above configuration, the position of the caster 91 in the direction of the axis V1 can be adjusted by rotating the caster 91 about the axis V1. Furthermore, after the position of the caster 91 is adjusted, the positioning nut 966 is brought into contact with the support plate 90 to restrict the rotation of the shaft member 965, thereby maintaining the caster 91 in the positioned position.

[0508] Therefore, after the height and inclination of the workbench 2 are adjusted, the workbench 2 can be held at the adjusted height and inclination.

[0509] (ii) The bracket 96 has:

[0510] The bottom portion 961 has a connecting plate 963 on one side in the direction of the axis V1 and a retainer 914 fixed on the other side in the direction of the axis V1. The shaft member 965 is connected to the connecting plate 963; and

[0511] The side wall portions 962 , 962 extend from both sides of the bottom portion 961 in the width direction toward the support plate 90 .

[0512] The positioning bracket 97 has:

[0513] a fixing portion 971 fixed to the lower surface of the support plate 90;

[0514] a connecting portion 972 extending from the fixing portion 971 along the axis V1 in a direction away from the support plate 90 ; and

[0515] The long hole 972a extending along the axis V1 passes through the connecting portion 972 in the thickness direction.

[0516] The screw Na passing through the long hole 972 a and the nut Nb threadedly engaged with the screw Na restrict relative movement along the axis V1 between the side wall portion 962 on the bracket 96 side and the connecting portion 972 on the positioning bracket 97 side.

[0517] If the through hole for the bolt on the connecting portion 972 side is a simple round hole, the bracket 96 supporting the caster 91 may not be connected to the positioning bracket 97 fixed to the support plate 90 depending on the height position of the caster 91.

[0518] As described above, if the bracket 96 is installed using the long hole 972a provided in the connecting portion 972, the long hole 972a can also be used to absorb the slight height deviation in the height direction of the caster 91 after height adjustment, so that the bracket 96 supporting the caster 91 can be properly fixed to the support plate 90.

[0519] (iii) The second position adjustment mechanism that supports the stopper 98 on the support plate 90 fixed to the leg portion 24 so as to be positionally adjustable in the direction of the axis V2 includes:

[0520] a shaft member 985 that passes through the through hole 902 provided in the support plate 90 in the direction of the axis V2 and has screw threads 985b provided on the outer periphery screwed into the screw threads 902a provided on the inner periphery of the through hole 902; and

[0521] The positioning nut 986 is threadedly coupled to the shaft member 985 .

[0522] The thread 902 a of the through hole 902 of the support plate 90 (fixed-side member) and the thread 985 b of the shaft member 985 of the stopper 98 constitute a screw feeding mechanism.

[0523] With the above configuration, the position of the stopper 98 in the direction of the axis V2 can be adjusted by rotating the stopper 98 about the axis V2. Furthermore, after adjusting the position of the caster 91, the stopper 98 is brought into contact with the installation surface G, and then the rotation of the shaft member 985 is restricted by the positioning nut 986, thereby maintaining the stopper 98 in the position in contact with the installation surface G.

[0524] Therefore, after the height and inclination of the workbench 2 are adjusted, the movement of the workbench 2 can be restricted by the stopper 98 .

[0525] (iv) The stopper 98 has the contact portion 981 having a larger diameter than the shaft member 985 at the lower end of the shaft member 985 .

[0526] A resin holder 99 is interposed between the contact portion 981 of the stopper 98 and the installation surface G.

[0527] The holder 99 includes an elastic member 995 on a surface in contact with the installation surface G, and includes a recessed portion 991 on a placement surface of the contact portion 981 with which the contact portion 981 engages.

[0528] With this configuration, the relative movement between the stopper 98 and the installation surface G can be reliably restricted.

[0529] (10) The table base 20 of the table 2 is provided with rails (the guide rail 52 and the rack rail 53 ) arranged along the X direction on the lower surface on the side edges 2 c and 2 d in the Y direction.

[0530] The rails (guide rails 52 and rack rails 53 ) are provided in a range from the side edge 2 a on one end side to the side edge 2 b on the other end side in the X direction.

[0531] The track (guide rail 52, rack rail 53) has:

[0532] The mounting and dismounting rails (mounting and dismounting guide rails 52A, mounting and dismounting rack rails 53A) are provided on the side edge 2a in a manner that allows for easy mounting and dismounting;

[0533] A mounting and dismounting rail (mounting and dismounting guide rail 52B, mounting and dismounting rack rail 53B) which is detachably provided on the side edge 2b; and

[0534] The fixed rails (fixed guide rail 52C, fixed rack rail 53C) are fixed to the lower surface of the table base 20 between the attachment and detachment rails on the side edge 2a and the attachment and detachment rails on the side edge 2b.

[0535] When connecting the work tables 2A and 2B to each other (shared work tables to each other), a connecting rail (connecting guide rail 52D, connecting rack rail 53D) is installed across one connected work table 2A and the other work table 2B to replace the mounting and disassembly rail (mounting and disassembly guide rail 52B, mounting and disassembly rack rail 53B) of one work table 2A and the mounting and disassembly rail (mounting and disassembly guide rail 52A, mounting and disassembly rack rail 53A) of the other work table 2B.

[0536] According to this configuration, when the tables 2 of a plurality of cutting plotters 1 are connected in the X direction, tables 2 of a common specification can be used for all the connected tables 2 .

[0537] Furthermore, there is no need to prepare separate workbenches with control panels 11 and connecting workbenches of different specifications. Preparing workbenches of different specifications would increase costs due to the increased number of components. By adopting a workbench 2 of universal specifications, the number of components can be reduced through commonality, leading to lower production costs.

[0538] Furthermore, when connecting multiple worktables 2, there is no need to calculate the required guide rail and rack lengths based on the total number of connected worktables 2 and prepare guide rails and racks of the required length each time. This reduces the time required to connect the worktables 2 and use the guide rails and racks. Consequently, the total time required to set up the cutting plotter 1 and connect the worktables 2 can be reduced.

[0539] The present invention can also be understood as a method for connecting a table 2 (common table) of a general specification for a cutting plotter 1 (processing device).

[0540] (11) The method for connecting the workbench 2 includes the following steps.

[0541] (a) Disassemble the mounting and disassembly rails (mounting and disassembly guide rail 52A, mounting and disassembly rack rail 53A) on one end side (side edge 2a side) of the workbench 2B to be connected and the mounting and disassembly rails (mounting and disassembly guide rail 52B, mounting and disassembly rack rail 53B) on the other end side (side edge 2b side) of the other workbench 2A to be connected.

[0542] (b) The side edge 2a of the table 2B to be connected is brought closer to the side edge 2b of the table 2A to be connected.

[0543] (c) The projections 510, 510 of the table 2B to be connected are inserted into the engaging holes 511, 511A (recesses) provided on the side edge 2b of the other table 2A to position the table 2B to be connected.

[0544] (d) The stopper 98 restricts the movement of the table 2B to be connected, thereby fixing the positional relationship between the other table 2A and the table 2B to be connected.

[0545] (e) Install a connecting rail (connecting guide rail 52D, connecting rack rail 53D) between the fixed rail (fixed guide rail 52C, fixed rack rail 53C) of the worktable 2B to be connected and the fixed rail (fixed guide rail 52C, fixed rack rail 53C) of another worktable 2A to complete the rail (guide rail 52, rack rail 53) from the side edge 2a of the other worktable 2A to the side edge 2b of the worktable 2B to be connected.

[0546] With this structure, the work platforms 2A and 2B are connected by inserting the protrusions 510 and 510 of one work platform 2B into the engaging holes 511 and 511A (recesses) of the other work platform 2A. The provision of casters 91 for movement facilitates movement of the work platform 2, shortening the time required to connect the work platforms 2A and 2B.

[0547] Thus, even if the total number of connected work tables 2 increases, the time required to connect the work tables 2 does not increase significantly, and thus the total number of work tables can be easily increased.

[0548] The following steps may also be included.

[0549] (f) Before or after the above step (a), adjust the height of the caster 91 after releasing the movement restriction performed by the stopper 98, adjust the level of the workbench table 21 of the workbench 2B of the connection object, and align the height of the workbench 2B of the connection object with the height of the other workbench 2A.

[0550] (g) After the above step (e), the movement of the table 2B is restricted by the stopper 98 .

[0551] According to this structure, the work tables 2 can be connected to each other after adjusting the height and inclination of the work table 2 , so the work tables 2 can be easily connected to each other.

[0552] The present invention is not limited to the above-described embodiments, and can be modified appropriately within the scope of the technical concept of the present invention.
