Description

  The present invention relates to a machining apparatus capable of machining a workpiece as a workpiece with a desired tool.

  Generally, for example, a processing apparatus for processing a relatively large workpiece represented by an NC router, for example, a processing head for performing a predetermined processing on a workpiece such as a router head or a boring head, and a placement on which the workpiece can be placed. And a mounting table on which a surface is formed. When machining the workpiece, the workpiece is positioned and fixed on the mounting surface by a clamp device or the like, and then the tool is attached to the machining head by moving the machining head relative to the mounting table. The workpiece is being processed.

Here, there are roughly two types of relative movement between the machining head and the mounting table.
First, the mounting table is fixed, while the machining head is moved in the 6-axis direction including the X-axis, Y-axis, and Z-axis, or these rotation axes. In this case, since a complicated drive mechanism is mounted on the machining head, not only the weight of the machining head is increased, but also the mechanism itself is enlarged.
In order to eliminate such disadvantages, the second form is a form in which the mounting table is configured to be movable, for example, in one axis in the X direction, and the machining head is driven in the Y direction and the Z direction. That is, in the horizontal direction, it is possible to reduce the weight and accuracy of the machining head by separating the drive between the mounting table and the machining head.

  In recent years, in order to improve processing efficiency and differentiate from other devices, for example, by mounting a plurality of processing heads on one mounting table as exemplified in Patent Documents 1 to 4 below. It has also been proposed to simultaneously machine multiple workpieces.

However, the conventional machining head as described above includes the following problems, and it can be said that there is still room for improvement.
That is, according to Patent Document 1, although a plurality of workpieces can be simultaneously processed by a plurality of processing heads, the processing head is moved in the horizontal direction by two drive sources arranged on both sides. Not only does the apparatus scale become relatively large, but also power consumption increases.

  On the other hand, according to Patent Documents 2 to 4, a plurality of machining heads can be moved with a single drive source in the horizontal direction, so that a reduction in size and weight can be achieved as compared with Patent Document 1. Is possible. However, in these Patent Documents 2 to 4, since the intervals between the plurality of processing heads are fixed, the work that can be processed is inevitably limited, and until various processing requirements are sufficiently met. Not reached.

  The present invention has been made in view of, for example, solving the above-described problems, and provides a machining apparatus capable of responding to various workpiece machining requests while suppressing an increase in apparatus scale.

Follow to the constitution to be moved in the second direction.

  In the processing apparatus of (1), (2) a first vertical drive mechanism that moves the first processing head in a third direction intersecting the first direction and the second direction, and the first vertical driving mechanism. It is preferable to further include a second vertical drive mechanism that moves the second processing head in the third direction independently of the drive mechanism.

  In the processing apparatus of (1) or (2), (3) the first horizontal drive mechanism extends in the second direction in parallel with the linear support member so as to sandwich the linear support member. It is preferable to include a pair of existing linear guides.

  In the processing apparatus according to (3), (4) the first horizontal drive mechanism includes a drive shaft extending in the second direction and a drive motor for rotating the drive shaft, One of the pair of linear guides is preferably disposed between the drive shaft and the linear guide.

  Further, in any of the above processing devices (1) to (4), (5) a position detection device for detecting a position of the first processing head in the second direction, and the second processing head of the second processing head. It is preferable that a fixing member for fixing a position in two directions is further provided, and an interval between the first processing head and the second processing head is set by the fixing member and the position detection device.

  In the processing apparatus according to any one of (1) to (5), (6) a Y linear guide that is laid in the first direction and guides the movement of the mounting table, and the first processing. And a tool table on which a processing tool that can be mounted on the second processing head is mounted, and the tool table preferably moves on the Y linear guide that is common to the mounting table.

  According to the present invention, the machining head is moved by the linear support member and the clamp member mounted on the machining head while suppressing an increase in the scale of the apparatus by moving a plurality of machining heads in one horizontal direction with one drive source. It is possible to arbitrarily set the interval between them to meet various workpiece machining requirements.

Embodiments of the present invention will be specifically described with reference to the drawings.
Below, among the processing apparatuses which can implement this invention suitably, the cutting processing apparatus which performs cutting is demonstrated to an example. However, it is needless to say that the present invention is not limited to a cutting apparatus, and can be widely applied to a processing apparatus that processes a workpiece, such as a grinding apparatus that performs grinding.

Are defined as a Z direction (a third direction intersecting the first direction and the second direction), respectively, but such definition does not limit the present invention.

<< First Embodiment >>
FIG. 1 shows a processing apparatus 100 according to the first embodiment. The processing apparatus 100 can process a workpiece W (not shown) using a predetermined tool t (see FIG. 2 and the like). The processing head 10, the mounting table 20, the processing mechanism 10 and the mounting table 20 are included in the processing apparatus 100. The driving mechanism for driving and the control device 60 are included at least.

Here, the workpiece W suitable for the present embodiment is not particularly limited. For example, a woodwork (woodworking piece or woodworking plate), a metal object (metal piece or metal plate), or a resin (resin piece or A workpiece such as a resin plate) is exemplified.
Further, the above-described tool t may be of any form including a cutting tool as long as it can cut the workpiece W, but an optimum shape and material blade is selected depending on the material of the workpiece W.

As shown in FIG. 1, the processing head 10 is mounted on the frame 1, and a mounting table 20 is disposed in the frame 1 below the processing head 10.
Note that, in the processing apparatus according to the present embodiment, other than the configuration and functions described in detail below, known mechanisms disclosed in, for example, JP 2010-46781 A and JP 2010-5710 A are used. You may apply suitably, unless it deviates from the meaning.

  The frame 1 is a mechanical structure made of, for example, a known mechanical structural alloy or steel, and has a function of mounting a processing head 10 to be described later, a driving mechanism for driving the processing head 10, or a fixing member 15 to be described later. have. The frame 1 of the present embodiment has a portal structure, and a mounting table 20 described later is installed in the frame 1 so as to be movable in the Y direction.

  The processing head 10 can mount a tool t such as a router for processing the workpiece W, for example, and processes the workpiece W placed on the placement table 20 into a desired shape using the tool t. The machining head 10 of this embodiment is mounted on the frame 1 and can be moved in the X direction. In the present embodiment, the machining head 10 is arranged such that two first machining heads 10a and two second machining heads 10b are arranged along the X direction.

As described above, in the present embodiment, since a plurality of processing heads are juxtaposed, a plurality of workpieces W placed on one mounting table 20 can be processed simultaneously in parallel. .
Hereinafter, when the matters common to the first machining head 10a and the second machining head 10b are described, they are collectively referred to as the machining head 10, and the unique items are individually described.

Next, with reference to FIG. 1 and FIG. 2, the drive mode in the machining head 10 of this embodiment will be described. As shown in the figure, the machining apparatus 100 includes a first horizontal drive mechanism (X drive mechanism) 30 that moves the machining head 10 in the X direction (second direction).
In the present embodiment, the X drive mechanism 30 as the first horizontal drive mechanism includes at least an X drive shaft 31, an X drive motor 32, and an X linear guide 33.

Among these, the X drive shaft 31 is a known screw shaft and constitutes a part of a ball screw mechanism with the first machining head 10a. The X drive shaft 31 of the present embodiment is mounted on the frame 1 so as to extend in the X direction (second direction).
The X drive motor 32 is a known electromagnetic motor that similarly constitutes a part of a ball screw mechanism with the first machining head 10a, and has a function of rotating the X drive shaft 31 described above. The X drive motor 32 of this embodiment is mounted on the frame 1 in the same manner as the X-axis shaft 31. As described above, in the present embodiment, the first processing head 10a can move linearly along the X direction by the ball screw mechanism.

  Note that, as will be described later, the second machining head 10b does not directly receive power from the X drive motor 32, and follows the movement of the first machining head 10a via the linear support member 11. Accordingly, the second machining head 10b is formed with a through-hole through which the X-axis shaft 31 passes, and is in a non-contact state, for example, so that the rotation of the X-axis shaft 31 is not transmitted to the second machining head 10b. Yes.

A plurality of (two in the present embodiment) X linear guides 33 are juxtaposed along the X direction, and include a rail laid on the frame 1 and a slider mounted on the processing head side and moving on the rail. . In the present embodiment, the X linear guide 33 is X linear guides 33a and 33b that are spaced apart from each other by a predetermined distance in the Z direction, and the movement of the machining head 10 in the X direction is guided by these linear guides. The More specifically, as shown in FIG. 2, the X linear guides 33a and 33b extend in the second direction in parallel with the linear support member 11 so as to sandwich the linear support member 11 described later in the Z direction. Are arranged as follows.
A specific example of the X linear guide 33 is not particularly limited, and various known linear guide mechanisms can be applied. For example, a known rolling bearing mechanism (linear motion bearing unit) using balls may be applied, or a rack A guide structure using an & pinion mechanism may be used.

As shown in FIG. 2, the X linear guides 33 a and 33 b are both mounted on the frame 1 at a position below the X drive shaft 31. Thereby, the machining head 10 is precisely guided in the X direction by the X linear guide 33.
In the present embodiment, a total of two X linear guides 33 are used. However, the present invention is not limited to this mode. For example, one X linear guide 33 may be used, or three or more X linear guides 33 may be used. May be.
In the present embodiment, the first machining head 10a and the second machining head 10b are installed on the common X linear guide 33 via the slider, but the present invention is not limited to this mode. For example, the first machining head 10a and the second machining head 10b may be installed on different X linear guides 33. In this case, for example, each of them may occupy two X linear guides.

As shown in FIGS. 1 to 3 and the like, the first machining head 10a is a clamp that clamps a part of the linear support member 11 extending in the second direction (X direction) intersecting the first direction (Y direction). A member 13 is provided. The first machining head 10 a has a function of machining the first workpiece W ₁ placed on the placement table 20.

The linear support member 11 is a member for assisting the movement of the other machining head so that the distance between the machining heads can be adjusted while following the movement of the other machining head.
One end side of the linear support member 11 of this embodiment is fixed to the linear support member fixing portion 12 of the second machining head 10b, and the other end side is opened (also referred to as an open end). The length of the linear support member 11 may be set as appropriate depending on the scale of the processing apparatus 100, but as an example, the distance between the first processing head 10a and the second processing head 10b is 600 mm at the maximum. The total length is set.
In this embodiment, the linear support member 11 is exemplified by a rod-like linear shaft made of, for example, a rigid steel material. Therefore, the description will be continued below using the linear shaft 11 as an example of the linear support member 11 as appropriate. However, the cross section of the linear support member 11 is not limited to a circle as described later with reference to FIG. It may be a structure.

  In addition, there is no particular limitation on a specific example of the linear support member fixing portion 12 (hereinafter, also referred to as “linear shaft fixing portion 12”), and various known types can be used as long as the linear shaft 11 is fixed without coming off. Fixing method can be applied. For example, it is conceivable to provide a female screw on a part of one end of the linear shaft 11 and fasten with a female screw via the linear shaft fixing portion 12. Alternatively, the linear shaft 11 may be fixed by press-fitting the linear shaft 11 as a concave portion and the linear shaft fixing portion 12 as a convex portion, or a known adhesive or a screwing member may be used.

Note that the linear shaft 11 of the present embodiment is disposed between the pair of X linear guides 33 so as to be sandwiched between the pair of X linear guides 33a and 33b in the Z direction.
In addition, an X linear guide 33 a that is one of the pair of X linear guides 33 is disposed between the X drive shaft 31 and the linear guide 11 in the Z direction.
Thereby, the movement in the X direction of the first machining head 10a with the second machining head 10b to be described later becomes smooth, and it is possible to suppress unintended swinging and rattling.

The clamp member 13 has a function of clamping (gripping) a part of the linear shaft 11. Specific examples of the clamp member 13 include a known air clamper (clamp cylinder) using compressed air, a known hydraulic clamper, a known screw clamper, and the like. In the present embodiment, a known air clamper using compressed air is applied among the clampers of the respective methods described above.
In the present embodiment, as will be described later with reference to FIG. 5, a plurality of (two) clamp members 13 are provided on the first machining head 10a, but the present invention is not limited thereto. That is, the number of the clamp members 13 may be one, or three or more.

  Further, the processing apparatus 100 according to the present embodiment includes a vertical drive mechanism 40 that moves the processing head 10 in the Z direction (a third direction intersecting the first direction and the second direction). More specifically, in the present embodiment, each of the first machining head 10a and the second machining head 10b has its own vertical drive mechanism 40, and adjusts its own Z position regardless of the other Z position. Is possible.

  That is, as shown in FIG. 2B, the machining apparatus 100 of the present embodiment is independent of the first vertical drive mechanism 40a that moves the first machining head 10a in the third direction and the first vertical drive mechanism 40a. And a second vertical drive mechanism 40b for moving the second machining head 10b in the third direction. The first vertical drive mechanism 40a and the second vertical drive mechanism 40b may be the same type of drive mechanism such as a known ball screw, or may be different drive mechanisms such as a known air cylinder mechanism and a ball screw drive mechanism. May be applied. In this embodiment, a known ball screw mechanism is applied.

As described above, in this embodiment, each driving mechanism 10 is mounted with its own drive mechanism for driving the machining head 10 in the Z direction (third direction). Thus, for example, a first workpiece W ₁ during machining in the first machining head 10a, it is possible to machine the second workpiece W ₂ in the second working head 10b in parallel. Further, the first workpiece W ₁ during machining in the first machining head 10a, a second working head 10b becomes possible waiting in a position spaced in the Z direction from the mount table 20 without machining .

On the other hand, the second machining head 10b of the present embodiment includes a linear shaft fixing portion 12 to which the above-described linear shaft 11 is fixed. The second working head 10b has a function of performing processing for the second workpiece W ₂ which is placed juxtaposed to the mount table 20 in the first working head 10a. In the present embodiment, the clamp member 13 provided in the first processing head 10b can clamp an arbitrary position of the linear shaft 11.

Therefore, in this embodiment, the 1st processing head 10a which clamped the linear shaft 11 with the clamp member 13 moves by the 1st horizontal drive mechanism, and the 2nd processing head 10b follows the movement of the 1st processing head 10a. To move in the second direction.
In other words, the second machining head 10b of the present embodiment does not have a drive mechanism for moving in the X direction, and is a system that follows the X machining direction integrally with the first machining head 10a. ing.

  In the present embodiment, the first processing head 10a and the second processing head 10b can be freely adjusted using the linear shaft 11 and the clamp member 13, so that the first processing head 10a and the second processing head 10b are separated from each other. There is a possibility of contact. Therefore, at least one of the first machining head 10a and the second machining head 10b is not essential, but may be provided with a collision preventing member 17 for preventing a collision with the other.

In this case, as a specific example of the collision preventing member 17, a physical member such as a pin member having a predetermined length may stand on the surface of the machining head 10 on which the collision is a concern, or a known distance. You may make it detect non-contact as a measurement sensor.
As shown in FIG. 2, in this embodiment, the collision preventing member 17 is provided on the side surface of the first processing head 10a that faces the second processing head 10b.

Moreover, when using the pin member of 1 or several predetermined length as the collision prevention member 17, you may set the length of this pin member to the minimum space | interval between both process heads. As a result, when the distance between the first processing head 10a and the second processing head 10b is minimized, the positional relationship can be adjusted relatively easily.
When a plurality of pin members are used as the collision preventing member 17, for example, they may be juxtaposed at predetermined intervals in the Z direction, for example, or juxtaposed at predetermined intervals in the Y direction. Alternatively, they may be juxtaposed at predetermined intervals with respect to the Y direction and the Z direction.
A known elastic member such as rubber or a spring may be installed at the tip of the collision preventing member 17. As a result, the shock is alleviated in the event of a collision.

Further, since the interval between the first machining head 10a and the second machining head 10b only needs to change the clamping position of the linear shaft 11 by the clamp member 13, the interval between the machining heads can be easily adjusted. ing.
Thereby, not only can the drive mechanism of the machining head in the X direction be reduced in size and power consumption, but also a plurality of workpieces W of various dimensions can be machined in parallel.

Returning to FIG. 1, the description of each component of the processing apparatus 100 is continued.
The mounting table 20 is disposed so as to face the above-described processing head 10, and the portal frame 1 is installed so as to straddle the mounting table 20. Further, as shown in FIG. 2 and the like, in this embodiment, the mounting table 20 is supported on the table support base 23 arranged in the frame 1 together with a Y drive mechanism 50 described later. A work placement surface 22 having one or a plurality of work suction holes 21 is provided on the top surface of the placement table 20.
The workpiece suction hole 21 is connected to a negative pressure generation source (such as a negative pressure pump) (not shown) via a vacuum pipe 24. As described above, the mounting table 20 according to the present embodiment has a function of sucking the work placed on the mounting table 20 under the control of the control device 60 described later.

Next, the Y drive mechanism 50 that drives the mounting table 20 in the Y direction (first direction) will be described in detail.
As shown in FIG. 2, the processing apparatus 100 according to the present embodiment includes a Y drive mechanism (second horizontal drive mechanism) 50 that drives the mounting table 20 in the first direction.
The Y drive mechanism 50 as the second horizontal drive mechanism includes a Y drive shaft 51, a Y drive motor 52, and a Y linear guide 53.

The Y drive shaft 51 is a known screw shaft like the above-described X drive shaft, and constitutes a part of a ball screw mechanism with the mounting table 20. And the Y drive shaft 51 of this embodiment is installed so that it may extend in a Y direction (1st direction).
The Y drive motor 52 is a known electromagnetic motor that similarly constitutes a part of a ball screw mechanism with the mounting table 20, and has a function of rotating the Y drive shaft 51 described above. Thus, in this embodiment, the mounting table 20 can be moved linearly along the Y direction by the ball screw mechanism.

  As is clear from FIG. 2A, a plurality of Y linear guides 53 (two in this embodiment) are juxtaposed in the X direction, and the X linear guides 53a and 53b are laid so as to sandwich the Y drive shaft 51. Has been. As a specific example of the Y linear guide 53, there is no particular limitation like the X linear guide, and various known linear guides can be applied. For example, a known rolling bearing mechanism (linear motion bearing unit) using a ball is applied. Alternatively, a guide structure using a rack and pinion mechanism may be used.

The control device 60 includes, for example, a CPU having a calculation function, a memory for storing various information, an input device for inputting information (such as a keyboard), an output device for outputting and displaying information (such as a liquid crystal display), and the like. Computer. Then, the operator can input the optimum machining conditions for the workpiece with the input device, and check the result with the above-described output device.
Note that machining programs and the like corresponding to various machining modes may be stored in the memory in advance. Moreover, the aspect which controls the processing apparatus 100 remotely via a network for the control apparatus 60 may be sufficient.

<Origin flow (part 1)>
Next, an operation for acquiring position information of the first processing head 10a and the second processing head 10b will be described. For example, since the position information of the machining head 10 is once erased when the apparatus is turned on, it is necessary to perform the origin search as an initial operation when the apparatus is turned on. If the distance between the processing heads can be measured using an optical sensor such as an interferometer, for example, only the reference position of one of the processing heads needs to be measured.
However, the processing apparatus 100 according to the present embodiment is not generally assumed to be used in a clean room or the like in which temperature and humidity are precisely controlled, and measurement is performed when an optical sensor such as an interferometer or an encoder is used. There is a risk of frequent errors.
Therefore, in the present embodiment, the origin finding flow that can be applied to the above-described environment is created as follows.

  That is, as shown in FIG. 4, first, as Step 1, it is confirmed whether or not the clamp member 13 clamps the linear support member (linear shaft) 11. If the clamp member 13 does not clamp the linear support member 11, the clamp operation is performed in step 1-2 and then the process proceeds to step 2. Note that step 1 is not essential, and step 1 may be omitted as long as the clamp by the clamp member 13 is in a standard state.

  Next, in step 2, the first machining head 10a is moved to the reference position Q. More specifically, the control device 60 controls the X drive mechanism 30 so as to move the first machining head 10a to the reference position Q. At this time, the first position detection device 14a is arranged at a position corresponding to the reference position Q of the frame 1, and the control device 60 determines whether the first machining head 10a is based on the detection result of the first position detection device 14a. It is determined whether or not the reference position Q has been reached. In addition, as a specific example of the above-described first position detection device 14a, there is no particular limitation, and various known sensors can be applied. For example, a sensor that detects physical contact, a sensor that electrically detects, or a highly accurate sensor. In the case where it is not necessary to detect the position, a sensor that detects optically may be used.

After the first machining head 10a reaches the reference position Q, in step 3, the control device 60 stores the position of the first machining head 10a in the X direction as the origin.
In step 2 described above, the second machining head 10b moves following the first machining head 10a, but at the time of step 3, the position of the second machining head 10b in the X direction remains unknown. Accordingly, in the next step 4, an operation for determining the position of the second machining head 10b is executed.

  That is, in step 4, the second machining head 10b is moved to the fixed position P. In this case, by controlling the X drive mechanism 30 to move the first machining head 10a, the second machining head 10b moves in the X direction following the movement of the first machining head 10a. When the above-described collision prevention member is provided in the first machining head 10a or the second machining head 10b, the second machining head 10b is pushed and moved by the first machining head 10a after releasing the clamp. Also good.

  Here, the second position detection device 14b is arranged at the fixed position P. The control device 60 determines whether or not the second machining head 10b has reached the vicinity of the fixed position P based on the detection result of the second position detection device 14b. As a specific example of the second position detection device 14b, there is no particular limitation as in the case of the first position detection device 14a. A sensor that detects physical contact, a sensor that electrically detects, or a publicly known sensor that optically detects. Various sensors may be applied.

  Then, after the second processing head 10b has reached the vicinity of the fixing position P in Step 4, in Step 5, the clamping operation by the clamp member 13 is released and the operation of fixing the position of the second processing head 10b by the fixing member 15 is performed. Is executed. In this case, a specific example of the fixing member 15 includes a fixing pin that can be pushed out of a cylinder head provided in the frame 1.

  More specifically, for example, a receiving recess 15r into which the fixing member 15 is inserted is also provided in the second processing head 10b, and the fixing member 15 is inserted into the receiving recess 15r of the second processing head 10b that has reached the fixing position P. And may be fixed. At this time, it is preferable that the fixing pin as the fixing member 15 has a tapered shape at the tip end side, so that even if there is some error, the fixing member 15 may be slid into the receiving recess 15r. It becomes possible.

Here, with reference to FIG. 5, the connection relationship of the processing head 10, the linear support member (linear shaft) 11, the clamp member 13, and the fixing member 15 in this embodiment is explained in full detail.
As shown in FIGS. 5A to 5E, the linear support member 11 is fixed to the linear support member fixing portion 12 of the second processing head 10b and is clamped by the clamp member 13 mounted on the first processing head 10a. It is possible to be clamped.
Among these, the clamp member 13 is comprised including the 1st clamp member 13R and the 2nd clamp member 13L so that two may be juxtaposed in the X direction.

As described above, when the second processing head 10b reaches the fixing position P, the receiving recess 15r provided in the second processing head 10b faces the fixing member 15 provided in the frame 1. Therefore, after that, the control device 60 executes the control of driving the fixing member 15 and inserting the fixing member 15 into the receiving recess 15r.
As a result, the second machining head 10b is fixed at the fixed position P by the fixing member 15. Since the fixed position P is naturally a known position, the absolute position of the second machining head 10b is determined through the above steps.

As shown in FIGS. 2 and 5, in the present embodiment, one fixing member 15 is provided. However, the fixing member 15 is not limited to this mode, and a plurality of fixing members 15 may be arranged in the Z direction, or a plurality of fixing members 15 may be arranged in the X direction. A plurality of X directions and Z directions may be arranged.
Further, in the present embodiment, the reference position Q is set to the left end (see FIG. 2 and the like), and the fixed position P is installed 600 mm to the right of the reference position Q (see FIG. 2 and the like). The position may be set as the reference position Q or the fixed position P.

As described above, in the present embodiment, the fixing position P by the fixing member 15 is an absolute reference whose position is known in advance, and the second processing head 10b is fixed by fixing the second processing head 10b at the fixed position P. Is determined in the X direction.
Furthermore, in this embodiment, it is preferable to release the clamp by the clamp member 13 prior to the fixing by the fixing member 15. When the clamp member 13 releases the clamp in advance, the second processing head 10b can be moved relative to the first processing head 10a in the X direction, and the fixing member 15 slides into the receiving recess 15r. When inserted, the second machining head 10b can finely move in the X direction.

The releasing of the clamp by the clamp member 13 is not limited to being performed before the fixing member 15 is inserted into the receiving recess 15r, and may be performed in parallel with the insertion of the fixing member 15 into the receiving recess 15r. .
Further, if the position of the first machining head 10a is not fixed in step 5, it is not necessary to release the clamp by the clamp member 13 in step 5.

Next, at step 6, it is determined whether or not a predetermined time has elapsed since the fixing member 15 was inserted into the receiving recess 15r. A specific example of the predetermined time is not particularly limited, but may be an arbitrary time of several seconds to several tens of seconds, for example.
When a predetermined time has elapsed in step 6, the clamp member 13 clamps the linear support member 11 in step 7. Thereby, the positional relationship between the first machining head 10a and the second machining head 10b is fixed.

Next, at step 8, the control device 60 calculates the positions of both machining heads and stores the head spacing. In this embodiment, since the reference position Q and the fixed position P are positioned 600 mm apart, the head interval is stored as 600 mm.
If the clamping operation is not released in step 5 and the fixing member 15 is slid into the receiving recess 15r, the first machining head 10a is moved in the X direction by the amount corresponding to the sliding movement. In consideration of this, the head interval is calculated. More specifically, in the present embodiment, the control device 60 stores a value obtained by subtracting the position of the first machining head 10a from the maximum distance 600 mm as the distance between both machining heads.

Next, in step 9, the fixing of the second machining head 10b by the fixing member 15 is released. Thereafter, control is performed to move the first machining head 10a based on the reference position Q (origin). On the other hand, the position of the second machining head 10b is controlled based on information that takes into account the stored head spacing.
As described above, in this embodiment, the interval between the first processing head 10a and the second processing head 10b is set by the fixing member 15 and the position detection devices (14a, 14b) described above.

<Spacing adjustment flow between machining heads>
Next, an interval adjustment flow between processing heads will be described with reference to FIG.
As described above, it is assumed that the processing apparatus 100 according to the present embodiment needs to change the interval between the processing heads depending on the specifications of the workpiece W in order to satisfy various processing requirements.
Below, the example which changes the said space | interval from 600 mm to 300 mm is demonstrated as an example which changes the space | interval between the processing heads once set.

That is, first, in Step A, the second machining head 10b is moved to the fixing position P in order to fix it. Specifically, for example, the same procedure as step 4 described above may be performed.
Next, in step B, the position of the second processing head 10 b is fixed by the fixing member 15. Specifically, for example, the same procedure as step 5 described above may be performed.
After the second machining head 10b is fixed at the fixing position P, the clamp by the clamp member 13 is released in Step C. As a result, the second machining head 10b can remain at the fixed position P without following the movement of the first machining head 10a.

In step D, the distance between the first machining head 10a and the second machining head 10b is adjusted, and control is performed to move the first machining head 10a so as to have a new gap of 300 mm. Here, since the origin of the first machining head 10a is already known, in this embodiment, the first machining head 10a may be moved to the second machining head 10b side by 300 mm with reference to this origin.
In the present embodiment, the example in which the interval between the processing heads is narrowed has been described. Needless to say, if the initial interval is not set to the maximum value, enlargement or reduction can be achieved by changing the interval in the middle.

After the distance between the two processing heads is updated in Step D, the clamp member 13 is clamped to the linear support member 11 in Step E to fix the distance between the two processing heads. Specifically, for example, the same procedure as step 7 described above may be performed.
Next, in step F, the distance between both processing heads is updated and stored, and the fixing by the fixing member 15 is released. Thereafter, the position of each machining head is controlled by the control device 60 based on the updated interval information between the machining heads.

  According to the first embodiment described above, the second machining head 10b including the linear support member 11 can move in the second direction following the movement of the first machining head 10a by the first horizontal drive mechanism. It is possible. Therefore, the movement of the plurality of machining heads in one horizontal direction is performed by one drive source, and an increase in the scale of the apparatus is suppressed, while the linear support member 11 and the clamp member 13 mounted on the machining heads prevent the machining heads from being moved. It is possible to arbitrarily set the interval to meet various workpiece W machining requests.

  Note that the second machining head 10b can be removed from the machining apparatus 100 when simultaneous machining by the first machining head 10a and the second machining head 10b is required. In this case, since the linear support member 11 is fixed on the second processing head 10b side, the linear support member 11 can also be removed at the same time, and the linear support member 11 is meaninglessly attached to the processing apparatus 100 even though it is not simultaneous processing. It is suppressed that it remains.

<< Second Embodiment >>
Next, a second embodiment of the processing apparatus according to the present invention will be described.
Hereinafter, differences from the first embodiment will be mainly described, and elements having the same configuration and function as those of the processing apparatus 100 described in the first embodiment are denoted by the same reference numerals as those in the first embodiment. Description and illustration will be omitted as appropriate.

  That is, as shown in FIG. 7, in the machining apparatus 200 of the second embodiment, the linear support member 11 is disposed on the other end of the linear support member 11 (on the side opposite to the linear support member fixing portion 12 side). This is different from at least the processing apparatus 100 of the first embodiment in that it includes a retaining member 16 that prevents the member from slipping out. In other words, in the first embodiment, the other end of the linear support member 11 is an open end, but in this embodiment, it is a non-open end.

  Specific examples of the retaining member 16 include a plate member, a cap member, or a protruding member such as a pin that can be fixed to the other end of the linear support member 11. The material of the retaining member 16 is not particularly limited, and examples thereof include a metal material or a resin material such as rubber or plastic. The method for fixing the linear support member 11 and the retaining member 16 is not particularly limited as long as it is detachable. For example, fastening by a screw structure or fixing by fitting may be performed.

  As described above, in the present embodiment, after the first processing head 10 a is inserted into the linear support member 11, the above-described retaining member 16 is attached to the other end of the linear support member 11. Therefore, even if the clamp member 13 breaks down for some reason, the first machining head 10a is prevented from being unintentionally detached from the linear support member 11, and the second machining head 10b is completely removed. It can be avoided that the position cannot be controlled.

As described above, the present invention has been described as the first embodiment and the second embodiment. However, the above-described embodiments can be variously modified without departing from the gist of the present invention.
Modified examples suitable for the first embodiment and the second embodiment will be described with reference to the drawings as appropriate. In the following description, the same reference numerals are assigned to the functions and configurations described above, and the description thereof is omitted as appropriate.

<Modification 1>
<Origin flow (part 2)>
First, as a first modification, an origin finding flow different from the origin finding flow described above will be described. In the embodiment described with reference to FIG. 4, priority is given to moving the first machining head 10 a to the reference position Q rather than holding the second machining head 10 b at the fixed position P. However, the present invention is not limited to this mode, and may be a mode in which the second machining head 10b is first fixed as shown in FIG.
Since the adjustment of the interval between the machining heads is the same as that in the above embodiment, the description thereof is omitted.

That is, as shown in FIG. 8, first, in step 10, it is confirmed whether the clamp member 13 is clamping the linear shaft 11.
When the clamp member 13 does not clamp the linear shaft 11, the control device 60 executes the clamping operation of the linear shaft 11 by the clamp member 13 in step 11. Steps 10 and 11 can be omitted as appropriate as described above.

  After the clamping by the clamping member 13 is confirmed, the second machining head 10b is moved to the fixed position P in step 12. In this case, by controlling the X drive mechanism 30 to move the first machining head 10a, the X machining mechanism 10 moves in the direction of the second machining head 10bX following the movement of the first machining head 10a. In addition, when the above-mentioned collision prevention member is provided in the 1st processing head 10a or the 2nd processing head 10b, it replaces with step 10 and step 11, and after releasing the clamp by the clamp member 13, the 1st processing head 10a. The second machining head 10b may be pushed and moved.

In this embodiment, since the distance between the two processing heads is unknown at the stage of step 12, the second position detection device 14b is essential at the fixed position P described above. Therefore, in step 12, the control device 60 detects whether or not the second machining head 10b has reached the fixed position P based on the detection result of the second position detection device 14b.
After the second machining head 10b reaches the fixed position P in step 12, the second machining head 10b is fixed to the fixed position P with the fixing member 15 in step 13. At this time, similarly to the above-described embodiment, the clamp by the clamp member 13 may be released in advance before the fixing member 15 is inserted into the receiving recess 15r. Accordingly, the fixed position P is naturally a known position, and thus the absolute position of the second machining head 10b is determined.
Also in this embodiment, the fixed position P and the reference position Q may be installed at arbitrary positions in the same manner as described above.

After the absolute position of the second machining head 10b is determined in step 13, an operation of releasing the clamp by the clamp member 13 is executed in step 14. Accordingly, the first machining head 10a can be moved to an arbitrary position while the position of the second machining head 10b remains unchanged (known).
Next, in step 15, the distance between the first processing head 10a and the second processing head 10b is adjusted. More specifically, the control device 60 controls the X drive mechanism 30 so as to move the first machining head 10a to the reference position Q. At this time, similarly to the above-described embodiment, the control device 60 determines whether or not the first machining head 10a has reached the reference position Q based on the detection result of the first position detection device 14a.

After the first processing head 10a reaches the reference position Q in step 15, the positional relationship between the first processing head 10a and the second processing head 10b is fixed in step 16. More specifically, the control device 60 performs control to clamp the linear shaft 11 with the clamp member 13 and fix the distance between both processing heads.
Next, at step 17, the position of the first machining head 10a is stored as the origin, and the distance between both machining heads is stored. Also in this embodiment, the reference position Q is stored as the origin, and 600 mm is stored as the distance between the two processing heads.
Next, at step 18, the fixing of the second machining head 10b by the fixing member 15 is released. Thereafter, control for moving the first machining head 10a with respect to the reference position Q is performed. On the other hand, the position of the second machining head 10b is controlled based on information in which the distance from the reference position Q is added to the distance of 600 mm.

<Modification 2>
<Origin flow (part 3)>
4 and 8, the second machining head 10b is moved in the X direction while basically maintaining the clamp by the clamp member 13. However, the present invention is not limited to this mode, and may be a mode in which the operator manually moves the second processing head 10b in the X direction as shown in FIG.

That is, as shown in FIG. 9, first, as step 21, it is confirmed that the clamping by the clamping member 13 is released. If the clamp member 13 is clamping the linear shaft 11, the control device 60 releases the clamp by the clamp member 13 in step 22.
After confirming that the clamp by the clamp member 13 is released, the second machining head 10b is moved to the fixed position P in step 23. In this case, for example, the operator may manually slide the second processing head 10b to the fixed position P.

After the second machining head 10 b has reached the fixed position P in step 3, the second machining head 10 b is fixed to the fixed position P with the fixing member 15 in step 4. In this case, for example, it can be performed in the same manner as step 5 in FIG.
After the absolute position of the second machining head 10b is determined in step 4, the distance between the first machining head 10a and the second machining head 10b is adjusted in step 5. In this case, for example, it can be performed in the same manner as step 15 in FIG.

After the first machining head 10a reaches the reference position Q in step 5, the positional relationship between the first machining head 10a and the second machining head 10b is fixed in step 6. More specifically, the control device 60 performs control to clamp the linear shaft 11 with the clamp member 13 and fix the distance between both processing heads.
Next, in step 7, the position of the first machining head 10a is stored as the origin, and the distance between both machining heads is stored.

Finally, in step 8, the fixing of the second machining head 10b by the fixing member 15 is released. Thereafter, control for moving the first machining head 10a with respect to the reference position Q is performed. On the other hand, the position of the second machining head 10b is controlled based on information that takes into account the interval between the reference position Q and the fixed position P.
It should be noted that the flow (No. 1) and (No. 2) for starting the origin described above are not affected by the presence or absence of the retaining member 16. In the origin-finding flows (Part 1) to (Part 3), the example in which the distance between the two processing heads is set to 600 mm has been described. Needless to say, any other distance may be used.

<Modification 3>
10 and 11 show a processing apparatus 300 according to the third modification. 10 is a perspective view of the processing apparatus 300 as viewed from the rear, and FIG. 11 is a front view and a side view of the processing apparatus 300.
The processing apparatus 300 according to the third modification is mainly characterized in that the connection table 25 is provided on the mounting table 20 and an ATC (automatic tool changer) table 70 is provided.
As shown in FIGS. 10 and 11, the ATC table 70 includes a tool holding portion 71, a connecting portion 72, and a slider 73.
In addition, although the processing apparatus 300 of the modification 3 mounts the 1st processing head 10a and the 2nd processing head 10b, it is not restricted to this aspect, One processing head 10 (for example, only the 1st processing head 10a) is provided. The form to mount may be sufficient. In such a case, it is sufficient that there is at least one processing head 10 and one mounting table 20, and the above-described linear shaft 11 and clamp member 13 are not essential and may be omitted as appropriate.

As also suitably shown in FIG. 10, the tool holding unit 71 is provided on the upper surface of the ATC table 70 and is a part where a plurality of types of tools are juxtaposed. In the present embodiment, for example, five tools, that is, a total of ten tools are juxtaposed for each machining head. When changing the tool, the machining head 10 is lowered via the vertical drive mechanism 40, so that a new tool held by the tool holding portion 71 can be mounted.
The tool holder 71 may be equipped with a lifting mechanism such as a known cylinder (not shown). In such a case, the tool holding unit 71 is also lifted appropriately so that the tool can be delivered to the machining head more quickly.

The connecting part 72 is a part for connecting to the connecting part 25 of the mounting table 20. As specific examples of the connecting portion 25 and the connecting portion 72, various known attaching / detaching mechanisms can be applied. For example, an attaching / detaching mechanism using a magnet or a mechanical attaching / detaching mechanism using a hook may be used.
The slider 73 is movably disposed on the rail of the Y linear guide of the mounting table 20 described above. In other words, the ATC table 70 is configured to move on the Y linear guide 53 that is common to the mounting table 20.

Next, the operation at the time of tool change will be described with reference to FIG. That is, when the tool is changed, first, the mounting table 20 is moved on the Y linear guide by the Y drive mechanism 50, and then the connecting portion 25 of the mounting table 20 comes into contact with the connecting portion 72 of the ATC table 70 to connect them. . Thereafter, the mounting table 20 moves on the Y linear guide 53 so as to pull the ATC table 70, so that the ATC table 70 is moved directly below the machining head 10. After that, the tool change of the machining head 10 is performed by the machining head descending via the vertical drive mechanism 40.
The ATC table 70 may store a cleaning brush that can be attached to the processing head 10. Thus, by attaching the cleaning brush to the processing head 10 at the end of processing, it becomes possible to efficiently clean the dust on the mounting table 20 after processing.

<Modification 4>
Next, FIG. 12 is a partial perspective view of the processing apparatus 400 according to the fourth modification.
The processing apparatus 400 of the fourth modification is mainly characterized in that it further includes a tool length measuring device 80. In the processing apparatus 400, the above-described collision prevention member 17 is not provided.

  The tool length measuring device 80 is configured to include a measurement reference surface 81 disposed in any region on the workpiece placement surface 22, for example. When measuring the length of the tool attached to the machining head 10 (referred to as the tool length), the control device 60 controls the movement of the mounting table 20 and the machining head 10 to control the movement of the machining head 10. The measurement reference plane 81 is positioned directly below the installed tool.

  Next, the control device 60 controls the Z drive mechanism 40 to lower the machining head 10 that measures the tool length. When the machining head 10 is lowered, the tool attached to the tip of the machining head 10 comes into contact with the measurement reference surface 81. Then, the control device 60 stops the lowering of the machining head 10 when the tool to be measured comes into contact with the measurement reference surface 81, and moves the machining head 10 and the mounting table 20 to a desired standby position or the like when the measurement is completed.

  In the fourth modification, the measurement reference surface 81 is disposed on the workpiece placement surface 22, but is not limited to this mode. For example, the measurement reference surface 81 may be installed on the placement table 20 other than the workpiece placement surface 22 or at a place other than the placement table 20 as long as the processing head 10 can reach.

<Other variations>
Next, FIG. 13 is a modification of the linear support member 11 in each of the above-described embodiments and modifications.
That is, in the above, the linear support member 11 was illustrated as a rod-shaped linear shaft whose cross section is a circle. However, the present invention is not limited to this mode. For example, as shown in FIGS. 13A and 13B, prismatic members having a rectangular cross section such as a triangle or a quadrangle may be used. Alternatively, it may be a rod-like member on which a protrusion for preventing rotation is formed as shown in FIG. 13 (c), or may be a spline shaft as shown in FIG. 13 (d).
Furthermore, the linear support member 11 is not limited to the rod-shaped shaft having each cross-sectional shape described above, and may have a structure such as an X linear guide 33. In such a case, for example, the second machining head 10b fixes and supports one end of an X linear guide having a desired length, and the first machining head 10a includes a slider that can move on the X linear guide. This form can be applied.
In these cases, the clamp surface of the clamp member 13 (the surface in contact with the linear shaft) also has a shape that follows the outer shape of the linear shaft 11 so as to correspond to the outer shape of each linear support member described above. Is preferred.

In addition, at least one of the X drive mechanism 30, the Z drive mechanism 40, and the Y drive mechanism 50 described in the above embodiments and modifications has a function of rotating a movement target around an axis (θ) in the movement direction. It may be.
More specifically, for example, in the case of the X drive mechanism and the Z drive mechanism 40, the machining head 10 may be rotated around the X axis (Xθ) or around the Z axis (Zθ). In the case of the Y drive mechanism 50, the mounting table 20 may be rotated around the Y axis (Yθ).

  Further, at least one of the first processing head 10a and the second processing head 10b has an injection device for spraying a fluid for blowing away scraps generated by processing toward the mounting table 20 and the workpiece W, and the above-described processing scraps. There may be a suction device for sucking the water. Various fluids such as gas and liquid are applicable as the fluid. For example, when the workpiece W is wood, a gas such as compressed air is suitable. When compressed air is applied as a fluid, the flow path of the compressed air supplied to the clamp member 13 may be used at least partially. For example, when cutting a metal as the workpiece W, oil, water, or the like may be applied as a fluid from the viewpoint of cooling and suppression of scattering of processing waste.

While various embodiments and modifications of the present invention have been described above, the processing apparatus of the present invention may be realized by appropriately combining the configurations of these embodiments and modifications.
In the above description, the cutting apparatus has been described as an example. However, the present invention can be applied to various processing apparatuses including a modeling apparatus such as a 3D printer.

  As described above, the processing apparatus of the present invention is suitable for realizing high-efficiency and low-cost work processing, and is not limited to cutting processing such as cutting processing or grinding processing, but includes various types including three-dimensional modeling processing. Applicable to various processing fields.
