Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a carriage moving device, for example, an automatic drawing device equipped with a carriage moving device, a plate making register mark automatic drawing device, and a coordinate reading device. And automatic processing devices such as cutting devices.

(Prior Art) In recent years, by moving a carriage guided reciprocally by a guide means via a carriage moving device, processing means such as a pen, a sensor, and a cutter are moved to perform processing on an object to be processed. Various automatic processing devices have been put to practical use.

Conventionally, in an automatic processing apparatus of this type, a carriage moving apparatus for reciprocating a carriage has a smaller influence of elongation than a carriage moving apparatus using a toothed belt or the like, and a rack moving apparatus can perform a stable moving operation. And a carriage moving means using a pinion.

However, the rack and pinion type has problems such as loud noise, high cost, and inability to increase the traveling speed too much.

Therefore, recently, as a solution to these problems, a metal flat belt, a so-called steel belt, is stretched so as to travel along the moving path of the carriage, and the movement of the steel belt during traveling is controlled. A carriage moving device configured to transmit the light to the carriage via the connecting means has been developed and is being put to practical use.

Generally, this kind of carriage moving device is provided with a carriage in a state where it is reciprocally movable and connected to each other with a guide rail provided in a parallel state as a guide, and furthermore, both ends of this carriage are moved along the guide rail. It is configured to be connected to first and second steel belts stretched so as to run via connecting means.

Further, the first and second steel belts are wound around drive pulleys connected via a synchronous shaft, run integrally in synchronization with each other, and move both ends of the carriage in the same direction and at the same speed. It is configured to be moved.

As described above, in the conventional carriage moving device, the moving accuracy of the carriage depends on the running accuracy of the first and second steel belts.

When a flat belt such as a steel belt travels via a pulley drive, the traveling (moving) distance L is determined by the diameter (D) of the drive pulley, the thickness (t) of the belt, and the rotation speed (N ).

L = N · π (D + t) Therefore, in a device in which A and B two drive pulleys are connected by a synchronous axis, the difference in diameter (D) of the two drive pulleys has a significant effect on the traveling distance (L). Have.

For example, D = 63.562, t = 0.1 (200mm pulley rotation)
In the device of (1), when moving by 1000 mm, if D _A = 63.562, L = 1000/200 × π × (63.562 + 0.1) = 1000.00 If D _B = 63.567, L = 1000/200 × π × (63.567 + 0. 1) = 1000.079 That is, a traveling distance error of a diameter difference ΔD × π × N occurs.

Even if ΔD is (63.567−63.562) = 5μ, it will be 0.
It will appear as a difference of 079mm.

These errors are due to the need for higher precision year by year in automatic drawing equipment, plate making register mark automatic drawing equipment,
Not only is an error not allowed in an automatic processing device such as a coordinate reading device or a cutting device, but also a torsion stress or the like is generated in a carriage or a member connecting the carriage, which causes a failure.

The drive pulley has a crown R for preventing meandering.
Also, a coating treatment with a high friction material for preventing slippage is performed, and it is very difficult to make the diameters of the two drive pulleys equal.

In addition, the trial calculation was performed on the assumption that the diameter of the two drive pulleys was set to a difference of 5 μ. However, it is actually difficult to keep the diameter within 5 μ, and about 20 μ is a guaranteed value.

Therefore, if the difference between the diameters of the two drive pulleys is to be kept within a required range, it becomes very expensive. For this reason, countermeasures have been taken by, for example, selecting the pairs by actually measuring the completed pulleys, but there is still a problem that sufficient accuracy cannot be obtained.

(Problems to be Solved by the Invention) Conventionally, in a carriage moving device using a running strip such as a steel belt, the moving distance of the carriage with respect to the moving distance of the running strip cannot be corrected, and the moving accuracy of the carriage can be corrected. Has a configuration that directly depends on the running accuracy of the running body.

Therefore, it is necessary to pursue the movement accuracy of the running body itself, it is extremely difficult to obtain the necessary movement accuracy, and there is a serious problem that the movement accuracy of the carriage cannot be increased to a certain level or more. .

In an automatic processing apparatus capable of performing processing on an object to be processed by moving a processing unit in accordance with the movement of a carriage, a conventional carriage moving apparatus has a carriage moving accuracy of a certain level or more. Because the movement accuracy cannot be increased to a certain level or higher, the processing such as recording, reading, and cutting that meets the needs of high accuracy cannot be performed. There was such a problem.

A second carriage (hereinafter, referred to as an X-direction carriage) 13 is reciprocally mounted on the X-direction guide rail 12, and a pen holder 14 is attached to the X-direction carriage 13 as shown in FIG. The pen 4 is mounted via the.

The Y-direction carriages 11a and 11b are provided with a Y-direction carriage moving device 15 as first carriage moving means.
In addition, the X-direction carriage 13 is provided with an X-direction carriage moving device 16 as a second carriage moving means.
, Each is moved by a predetermined amount.

The Y-direction carriage moving device 15 has the following structure.

That is, along the Y-direction guide rails 10a and 10b,
A flat belt of stainless steel having a thickness of about 1 mm, that is, a so-called steel belt 17a, 17b is stretched as a second running strip. These steel belts 17a, 17b are connected at both ends via a belt connecting plate 18, respectively.
It is formed endless.

Then, the right steel belt 17a is stretched in a horizontal state with the belt surface facing upward by being wound around a driving pulley 19a and a driven pulley 20a arranged at both ends of the Y-direction guide rail 10a. Further, the left steel belt 17b is stretched in a horizontal state with the belt surface facing upward by being wound around a driving pulley 19b and a driven pulley 20b arranged at both ends of the Y-direction guide rail 10b.

The steel belt 17a on the right side is not parallel to the Y-direction guide rail 10a but is inclined by about 0.48 °, and the front end is displaced outward by about 10 mm.

The drive pulleys 19a, 19b around which the steel belts 17a, 17b are wound have a shape having a crown R having a slightly larger diameter at a central portion in order to prevent meandering of the belt, and also prevent slippage. For this reason, the peripheral surface is coated with high friction material, and the drive pulleys 19a, 19
The driving force of b is transmitted to the steel belts 17a and 17b satisfactorily and reliably.

Also, as shown in FIG. 3, the right drive pulley 19a
Both ends 21a, 21b of the shaft 21 are supported by bearing members 23, 23 arranged side by side on a base 22, and a left drive pulley 19b (not shown) is also supported.

The drive pulleys 19a and 19b are connected to each other via a synchronous shaft 25 having a universal joint 24 in the middle as shown in FIG. Further, the driving force of a motor 27 as a driving source is transmitted to the synchronous shaft 25 via a speed reduction mechanism 26 composed of a gear group.

Furthermore, the steel belt 17a on the right side and the Y-direction carriage 11a are connected by first connecting means 30 described later, and the steel belt 17b on the left side and the Y-direction carriage 11b are connected by second connecting means 31. ing.

Thus, the driving force of the motor 27 is transmitted to the synchronous shaft 25 via the speed reduction mechanism 26, and further transmitted to the driving pulleys 19a and 19b. And the steel belts 17a and 17b run,
The Y-direction carriages 11a, 11b connected to the steel belts 17a, 17b via connecting means 30, 31 move in a predetermined direction.

That movement, by the forward rotation of the motor 27, Y-direction carriage 11a, 11b is moved in the forward direction (Y _F direction), the reverse rotation of the motor 27, Y-direction carriage 11a, and 11b is the rear direction (Y _R direction) I do.

With the movement of the Y-direction carriages 11a and 11b, the X-direction guide rail 12 on which the X-direction carriage 13 is movably mounted moves integrally. Thereby, the X-direction carriage
The positioning of 13 in the Y direction is performed.

On the other hand, the positioning of the X-direction carriage 13 in the X direction
This is performed by the directional carriage moving device 16.

As shown in FIG. 1, the X-direction carriage moving device 16 is provided with a steel belt 35 as a running strip stretched along the X-direction guide rail 12 by being wound around driving pulleys 33 and 34. Configuration. The driving force of the motor 36, which is the driving source, is reduced by a reduction mechanism comprising a group of gears.
The driving force is transmitted to the driving pulley 33 via the drive 37.

The operation of the Y-direction carriage moving device 15 and the X-direction carriage moving device 16 is controlled by control means (not shown).
Are arbitrarily sent in the X direction and the Y direction according to the image information. The pen 4 mounted on the X-direction carriage 13 is opposed to a predetermined position on the drawing paper 2.

On the other hand, in synchronization with this movement operation, a pen-up / down mechanism (not shown) attached to the pen holder 32 is operated, and the pen 4 is brought into and away from the drawing paper 2.

The horizontal movement of the pen 4 by the Y-direction carriage moving device 15 and the X-direction carriage moving device 16 and the vertical movement of the pen 4 by the pen-up / down mechanism draws a drawing on the drawing paper 2 according to the drawing information.

The portion of the synchronous shaft 25 of the Y-direction carriage moving device 15 and the drive pulley 33 of the X-direction carriage moving device 16
A rotation speed detector (not shown) using an encoder is arranged between the speed reduction mechanism 37 and the speed reduction mechanism 37. Then, the Y-direction carriages 11a and 11b and the X-direction carriage 1
The movement amount of the motor 3 is detected and fed back to motor controllers (not shown) of the motors 27 and 36, respectively.

Next, with reference to FIGS. 4 to 7, the structure of the first connecting means 30 for connecting the right Y-direction carriage 11a and the right steel belt 17a stretched at an angle will be described in detail. I do.

The first connecting means 30 is roughly divided into two members, that is, the first connecting member 50 attached to the steel belt 17a.
A second connecting member 51 attached to the Y-direction carriage 11a and movably connected to the first connecting member 50 in a direction (X direction) orthogonal to the moving direction of the Y-direction carriage 11a.
Consists of

The first connecting member 50 is a slide comprising a bearing holder 52 mounted on a connecting plate 18 for connecting both ends of the steel belt 17a, and two ball bush bearings (linear bearings) fitted and held by the bearing holder 52. Bearing 53,5
With 3.

The second connecting member 51 includes a shaft holder 54 attached via an L-shaped support member 56 attached to a side end surface of the Y-direction carriage 11a, and support pieces 54a, 54 of the shaft holder 54.
The slide shafts 55, 55, both ends of which are held by the b and the middle part slidably penetrate the slide bearings 53, 53.

Thus, according to the connecting means 30 configured as described above, the first and second connecting members 50, 51 are engaged with the slide bearings 53, 53 and the slide shafts 55, 55 by the fitting operation of the slide shafts 55, 55. It is relatively movable only in the 55 axis direction.

Therefore, the steel belts 17a is, in the normal rotation by the front direction of the motor 27 (Y _F direction), also when moving backward (Y _R direction) by the reverse rotation of the motor 27, its movement as it is in the Y-direction carriage 11a Is transmitted.

In addition, the Y-direction carriage due to misalignment or heat
The force (arrow ΔX) in the direction perpendicular to the direction of movement of 11a
1, slide bearings 53, 53 of the second connecting members 50, 51 and a slide shaft
It can be absorbed by the movement between 55 and 55.
As a result, unnecessary stress is not generated between the steel belt 17a and the Y-direction carriage 11a unlike the case of the conventional fixed connection, and the Y-direction carriage 11a
Straight running accuracy can be improved.

Therefore, the Y of the pen 4 mounted on the X-direction carriage 13 that moves with the movement of the Y-direction carriage 11a
High accuracy is ensured for movement in the direction.

As shown in FIG. 7, the angle between the bearing holder 52 holding the slide bearings 53, 53 and the shaft holder 54 holding the slide shafts 55, 55 with the running line _BL of the steel belt 17a can be changed. Thus, the mounting angle can be changed.

That is, the center of rotation of the bearing holder 52 is determined by the center pin 61 that penetrates the center pin insertion hole 60 formed substantially in the center of the belt coupling plate 18. The belt connecting plate is formed by fixing screws 64 that are inserted through a plurality of screw holes 63 that are formed at a certain distance from the center pin insertion holes 60 of the belt connecting plate 18 through the long holes 62 that are respectively formed in the belt connecting plate 18. 18 is fixed on. Therefore, when the fixing screws 63 are loosened, the bearing holder 52 can be displaced about the center pin 61 by an amount corresponding to the gap formed between the elongated holes 62 and the fixing screws 64. .

On the other hand, the rotation center position of the shaft holder 54 is determined by a center pin 67 that penetrates a center pin insertion hole 66 drilled at a substantially central portion of the horizontal piece 56a of the support member 56. The horizontal piece 56a is fixed to the lower surface of the horizontal piece 56a by a fixing screw 69 that penetrates a long hole 68 formed at a certain distance from the center pin insertion hole 66 of the horizontal piece 56a.

In the support means 70 thus configured, the center pin 61 of the first connecting member 50 and the center pin 67 of the second connecting member 51 are coaxial with each other, The positions match.

A notch 71 is formed at the end of the horizontal piece 56a of the support member 56, and the eccentric part 72a of the eccentric pin 72 for adjusting the correction amount, which is rotatably mounted on the shaft holder 54, is related to the notch 71. In this state, the rotation displacement means 73 is configured.

Then, by rotating the eccentric pin 72 by a driver or the like, the shaft holder 54 and the bearing holder 52 integrated therewith are rotated.
Can be rotationally displaced about the center pins 61 and 67 without difficulty.

And, as will be described later, a moving amount correcting means 74 capable of correcting the moving amount of the Y-direction carriage 11a with respect to the moving amount of the steel belt 17a is configured.

Next, the principle of correcting the moving amount by the moving amount correcting means 74 will be described with reference to FIGS.

FIG. 8 shows a steel belt 17 stretched in an inclined state.
FIG. 9 shows the state of movement of the carriage 11a and the carriage 11a, and FIG. 9 further illustrates the movement.

Here, C _L … carriage travel line B _L … belt travel line Θ… inclination angle between carriage travel line and belt travel line α… angle between slide shaft and carriage travel line (mounting angle of slide shaft to carriage) Α ′: angle between the slide shaft and the belt travel line “Θ + α + α ′ = 180 °” L ₀ : travel distance of the belt L: travel distance of the carriage

Then, as shown in the FIG. 10 (a), the alpha = set to (180-Θ) / 2, since it is alpha = alpha ', the L = L _0.

In conclusion, the traveling distance L ₀ of the belt 17a, is equal to the travel distance L of the carriage 11a to be transmitted by it.

Next, as shown in FIG. 10 (b), when setting α <(180−Θ) / 2, α ′> (180−Θ) / 2, ∴α <α ′, and L> L ₀ , L = L ₀ + m.

In conclusion, the running distance L ₀ of the belt 17a, the travel distance L of the carriage 11a carried by it becomes longer by m.

Conversely, as shown in FIG. 10 (c), when α> (180−Θ) / 2, α ′ <(180−Θ) / 2, ∴α> α ′, and L <L ₀ , L = L ₀ −n.

In conclusion, the running distance L ₀ of the belt 17a, the travel distance L of the carriage 11a carried by it is shorter by n.

That, m, the value of n, alpha, that is, by changing the mounting angle relative to the carriage traveling line C _L of the slide shaft 55 can be freely changed.

Moreover, linearly proportional to the travel distance L ₀ of the belt 17a, the amount is gradually added to the carriage movement.

Therefore, as shown in FIG. 1, the two drive pulleys 19a, 19
If α is set so as to cancel out the relative difference ΔL between the running distances of the belts 17a and 17b using a device connected to b, the running distances of the carriages 11a and 11b can be completely matched.

For example, the drive pulley 1 on which the steel belt 17a is hung
A state in which the distance between the axis of the driven pulley 9a and the driven pulley 20a is 1200 mm, the movement amount of the Y-direction carriage 11a is 1000 mm, one round of the driving pulley 19a (19b) is 200 mm, and one end of the steel belt 17a travels 10 mm ({0.48}). In the apparatus set in (1), correction of the relative difference (ΔL) of about 1.5 mm is sufficiently possible.

This is 0.1 mm in terms of the relative difference in pulley diameter (ΔD).
This is equivalent to a degree of error, and processing becomes very easy.

On the other hand, an X carriage connecting means (not shown) for communicating the X direction carriage 13 with the steel belt 35 is also of a sliding type similar to the first connecting means 30, and is used to move the pen 4 in the X direction. High accuracy is assured.

In this way, high accuracy is secured for the movement of the pen 4 in the Y direction and the X direction, and highly accurate drawing is possible.

Note that the second connecting means 31 and the X carriage connecting means have the same basic configuration as the first connecting means 30, and a detailed description thereof will be omitted.

In the above-described embodiment, the present invention is applied to an automatic drawing apparatus for moving a recording means such as a pen as a processing means. Is also good. Furthermore, a coordinate reading device in which the processing means is a reading means for reading information recorded on the object to be processed, a cutting device in which the processing means is a cutting means such as a cutter for cutting the object to be processed, or the like. It is needless to say that the present invention may be applied to an automatic processing apparatus having a carriage.

Further, the first connecting member 50 of the connecting means 30 is connected to the slide bearing 53.
In the above, the description has been given of the case where the second connecting member 51 is constituted by the slide shaft 55, but the reverse combination may be adopted.

Further, a slide bearing may be used as the slide bearing 53.

Further, the first connecting member 50 and the second connecting member 51
A plurality of guide bearings and guide rails may be combined so that the guide rail 63 can slide using the guide bearing as a guide.

Further, the belt 17a is described as having the inclination angle Θ of about 0.48 °, but is not limited thereto. However, a range of 1 ゜>Θ> 0.2 ゜ is a practical range because a large adjustment width can be obtained and the belt does not protrude too much.

In addition, it is needless to say that the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention.

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

In the carriage moving device according to the first aspect, the first and second connecting means for transmitting the movement of the running streak to the carriage.
By changing the angle between the moving direction of the connecting member and the running line of the running streak, the moving amount of the carriage with respect to the moving amount of the running streak stretched at a certain angle can be corrected. It is extremely easy to correct the amount of movement, and not only can the carriage be moved with high accuracy, but also it is not necessary to increase the dimensional accuracy of the drive pulley for moving the running body more than necessary. Improvement and reduction in manufacturing cost can be achieved.

According to the automatic processor according to the second aspect, the angle between the moving direction of the first and second connecting members of the connecting means for transmitting the movement of at least one running strip to the carriage and the running line of the running strip is determined. The change in the amount of movement of the carriage relative to the amount of movement of the running strip can be corrected, so that the difference in the amount of movement of the carriage moved by the two running strips can be corrected very easily. Movement can be performed with high accuracy. Accordingly, the processing means that moves together with the movement of the carriage can be moved with high accuracy, and highly accurate automatic processing on the object can be performed.
Also, there is no need to increase the dimensional accuracy of the drive pulleys for moving the running strip more than necessary, and the relative difference between the two drive pulley diameters does not matter so much. Cost can be reduced.

In the carriage moving device according to the third aspect, the first
Support means for supporting the connecting member and the second connecting member in a state having the same rotation fulcrum, respectively, and a traveling line of a running body traveling at an angle on the first and second connecting members supported by the supporting means. And a rotation displacement means for rotating the angle to change the angle of the carriage, an effect that the operation of correcting the amount of movement of the carriage with respect to the amount of movement of the running body can be extremely easily performed.
