Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking light device for a sewing machine for easily and accurately positioning a sewing material (body material) of an industrial sewing machine.

[0002]

2. Description of the Related Art Some industrial sewing machines are provided with a marking light device for the sewing machine. In such an industrial sewing machine, a marking light applied to a sewing material (hereinafter, body cloth) from a sewing machine marking light device is matched with a mark previously attached to the body cloth.
The body is positioned and the sewing work is performed. Generally, a monochrome light bulb or LED is used as a marking light source, and light from the light source is applied to a body through a slit plate and a lens.

[0003]

In the conventional marking light device for a sewing machine, the color of irradiation light is limited, and depending on the color and material of the body cloth, the reflected light of the marking light applied to the body cloth becomes thin. There was a problem that it was difficult to see. To solve this problem, there is a type that uses a laser beam with relatively high visibility, but in this type, the reflected light of the marking light applied to the body fabric,
Although it is clearly visible, there is a problem that eyes are easily tired due to high brightness light. Furthermore, in consideration of these problems, there is a marking light device for sewing machines that can adjust the light amount of the marking light by the operation of the operator, but the operator must adjust the light amount every time the fabric changes. However, there was a problem that the work was troublesome. In general,
In order to make the reflected light of the marking light easy to see, it is necessary to increase the amount of light regardless of the type of body material. However, when the amount of light increases, strong (dazzling) reflected light is generated when the mark on the body material and the marking light match, making it difficult to recognize whether the mark and the marking light match. As a result, there is a problem that it is difficult to match the mark and the marking light. In addition, for example, when the brightness (external light amount) of the workplace changes due to a change in the time of day or the weather, the appearance of the reflected light of the marking light changes accordingly, and the workability deteriorates. There was also a problem that there were cases.

An object of the present invention is to provide a marking light device for a sewing machine which makes it easy to see the reflected light of the marking light. Another object of the present invention is to provide a marking light device for a sewing machine that can easily recognize a matching state between a marking light and a mark.

[0005]

In order to solve the above-mentioned problems, according to the present invention, as shown in FIGS. 1 to 4, for example, as shown in FIGS. A marking light device 10 for a sewing machine for positioning the body cloth 3 by matching a marking light (irradiated portion 4) with a mark 3a previously attached to the body cloth 3 comprising the apparatus 1). A light receiving sensor 2 for receiving the reflected light of the marking light applied to the light source, and a light amount adjusting means for adjusting the light amount of the marking light so that the light amount of the reflected light received by the light receiving sensor becomes a preset light amount (for example, , CPU6
1).

According to the first aspect of the present invention, the light amount of the reflected light received by the light receiving sensor can be adjusted to the set light amount by the light amount adjusting means. The amount of reflected light of the marking light to be caught can always be constant. Therefore, it is possible to prevent the reflected light of the marking light from becoming thin and difficult to see depending on the color and the material of the body material, and preventing the eyes from easily becoming tired due to the reflected light being too bright. In addition, since the light amount of the marking light is automatically adjusted by the light amount adjusting means, the operator does not need to operate each time.

Here, since there is an individual difference in the amount of reflected light from the marking light having good workability, even if the amount of light is easy for one worker to see, it is difficult for another worker to see and the workability may deteriorate. .

Therefore, the invention described in claim 2 is based on claim 1.
In the marking light device 10 for a sewing machine described above, a set light amount changing unit (for example, the CPU 61 and the operation panel 7) for arbitrarily changing the set light amount is provided.

According to the second aspect of the present invention, since the set light amount can be arbitrarily changed by the set light amount changing means, for example, each time the operator changes, the set light amount is changed to a desired value, whereby each work can be changed. It is possible to work with a marking light of a convenient light amount for each user.

Here, even if the amount of reflected light from the marking light is always constant, the "appearance brightness" of the reflected light from the marking light depends on the brightness of the surrounding environment (external light amount).
Changes. Specifically, if the surrounding environment is bright, the reflected light of the marking light will be relatively dark and difficult to see, and if the surrounding environment is dark, the reflected light of the marking light will be relatively bright and the eyes may be easily tired. is there.

Therefore, the invention according to claim 3 is based on claim 1.
Or in the marking light device 10 for a sewing machine according to 2, wherein the extraneous light amount received by the light receiving sensor when the marking light 1a is not irradiated is increased or decreased with respect to a value stored in advance. Means (for example, CPU 61) and the extraneous light amount judging means, when it is judged that the extraneous light amount has increased, the light amount of the marking light is increased, and when it is judged that the extraneous light amount has decreased, A light amount correcting unit (for example, CPU 61) for reducing the light amount of the marking light is provided.

According to the third aspect of the present invention, since the light amount correcting means corrects the light amount of the marking light according to the external light amount, it is possible to always make the marking light easy to see according to the brightness of the surrounding environment.

The invention according to claim 4 is provided with an irradiating means (for example, an irradiating device 1) for irradiating the body light 3 with the marking light 1a as shown in FIGS. 4) and the marking light device 10 for a sewing machine for positioning the body cloth by matching the mark 3a preliminarily attached to the body cloth.

CPU 61).

According to the fourth aspect of the present invention, the color of the reflected light received by the light receiving sensor can be adjusted to the set color by the light color adjusting means. Since the color of the reflected light of the marking light captured by the camera can be always constant, the reflected light can always be easily seen. In addition, since the color of the marking light is automatically adjusted by the light color adjusting means, it is not necessary for the operator to operate each time.

Here, since there is an individual difference in the appearance of colors, even a color that is easy for one worker to see may be difficult for another worker to see, and the workability may be poor.

Therefore, the invention according to claim 5 is based on claim 4
In the marking light device 10 for a sewing machine described above, a setting color changing unit (for example, the CPU 61 and the operation panel 7) for arbitrarily changing the setting color is provided.

According to the fifth aspect of the present invention, since the set color can be arbitrarily changed by the set color changing means, for example, the set color can be arbitrarily changed each time the operator changes. It is possible to work with a marking light of a convenient color for each worker.

Here, depending on the color and material of the body material, the reflectance of the marking light of a specific color may be deteriorated.

The invention according to claim 6 is based on claim 4

In particular, since the irradiation mode is changed, for example,
Even when the sewing machine is used in a place where noise is large due to a sewing operation such as in a factory, the operator can easily recognize that the mark and the marking light match. As a method of changing the irradiation mode, it is conceivable to darken the marking light, change the color of the marking light, or blink the marking light.

Next, the control by the sewing machine marking light device 10 configured as described above and the work flow using the sewing machine marking light device 10 will be described in detail.

First, as shown in step S1 of FIG. 4 and FIG. 1, the marking light device 10 for the sewing machine is activated to irradiate the marking light 1a from the irradiating device 1, and the body cloth is irradiated under the irradiation of the marking light 1a. 3
Place. At this stage, the marking light 1
The irradiation part 4 of a is not matched with the mark 3a. This is because, as described below, a process of adjusting the reflected light 1b of the marking light 1a to the set light amount is performed.

<Adjustment to the Set Light Amount and Set Color> The process of adjusting the reflected light 1b of the marking light 1a to the set light amount is performed, for example, for each LED of the irradiation device 1. First, in step S2, among the LEDs of the irradiation device 1, the red LE
In step S3, only the amount of red component light included in the reflected light 1b received by the light receiving sensor 2 is temporarily stored in the RAM 63. In the following step S4, it is determined whether or not the light amount of the red component light stored in the previous step S3 is the same as the set light amount of the red component light. The data of the set light amount is stored in the RAM 63 in advance, for example. If it is determined in step S4 that they are not the same (normally, it is determined that they are not the same at the beginning of the work), the process proceeds to step S5. In step S5, it is determined whether or not the light amount of the red element light included in the reflected light 1b stored in the previous step S3 is the same as the light amount of the red element light of "light amount at the time of coincidence". Here, the light quantity at the time of coincidence refers to the reflected light 1 in a state where the irradiated portion 4 of the marking light 1a and the mark 3a coincide.
b is the amount of light. Similarly to the set light amount, the data of the “light amount at the time of coincidence” has a light amount for each element light (red, green, blue), and is stored in the RAM 63 in advance or there is no data. This is the state (usually, the amount of light at the time of coincidence is stored in the RAM, but, for example, when the apparatus is operated for the first time; the value is “0”). If it is determined in step S5 that they are not the same (normally, it is determined that they are not the same at the beginning of the work), the process proceeds to step S6. If the value of the light quantity at the time of coincidence is 0, step S5 is skipped and step S6 is performed. In step S6, the reflected light 1b received in the previous step S3
It is determined whether the light amount of the red component light included in is larger or smaller than the light amount of the set red light component light. If it is determined in step S6 that the light amount is small, the process proceeds to step S7, and the light amount of the red component light of the reflected light 1b received by the light receiving sensor 2 is the same as the light amount of the set red light. , The light emission amount of the red LED is increased. On the other hand, if it is determined in step S6 that the value is larger, the process proceeds to step S8 and the light receiving sensor 2
, So that the amount of the red component light of the reflected light 1b received at the same time is equal to the set amount of the red component light.
D reduces the amount of light emitted. Thus, the amount of red component light in the reflected light 1b is first adjusted to be equal to the set amount of light.

After step S7 or step S8, the process returns to step S2. When the same processing as described above is performed again in steps S2 to S4, this time, in step S4, the light amount of the red element light included in the reflected light 1b received in step S3 becomes the red element light of the set light amount. It is determined that the light amount is the same as the light amount, and the process proceeds to step S9.
In step S9, among the LEDs of the irradiation device 1, the green L
Irradiate only ED. Subsequent to step S9, the process of adjusting the light amount of the green component light in the reflected light 1b to be equal to the set light amount of the green component light is performed in the case of adjusting the red component light (step S9). Steps S3 to S8 are performed in the same manner as steps S2 to S4), and the process proceeds to step S10. In step S10, only the blue LED among the LEDs of the irradiation device 1 is irradiated. Subsequent to step S10, the process of adjusting the light amount of the blue component light in the reflected light 1b to be the same as the set light amount of the blue component light is performed in the case of the adjustment of the red component light (step Steps S3 to S8 are performed in the same manner as steps S2 to S9). As a result, the amounts of the red, green, and blue component lights of the reflected light 1b are set to be equal to the set amounts of the red, green, and blue component lights, respectively. As a result, the reflected light 1b becomes It is automatically adjusted to the set light quantity. Therefore, the reflected light 1b is automatically adjusted to the set color at the same time. Here, the CPU 61 functions as a light amount adjusting unit and a light color adjusting unit.

<Light amount correction> Subsequent to step S10,
Move to step S11. In step S11 and subsequent steps, it is determined whether the amount of extraneous light received by the light receiving sensor 2 when the marking light 1a is not irradiated is increased or decreased with respect to a value stored in advance. The light quantity of the marking light 1a is increased, and when it is determined that the extraneous light quantity is reduced, the marking light 1a
Is performed to correct the apparent brightness of the reflected light 1b to a desired value regardless of the brightness of the surrounding environment.

First, in step S11, a process of temporarily storing in the RAM 63 the data of the amount of extraneous light received by the light receiving sensor 2 while all the LEDs of the irradiation device 1 have stopped emitting light, To determine whether or not has changed with respect to a value previously stored in the RAM 63 (hereinafter, an external light amount storage value). It should be noted that the data of the stored external light quantity is stored in the RAM 63 in the previous step S11.
Is the data of the extraneous light amount stored in
(For example, when operating the device for the first time, there is no data). If it is determined in step S11 that the extraneous light quantity has changed with respect to the extraneous light quantity storage value, the process proceeds to step S12, and it is determined whether the extraneous light quantity has increased or decreased with respect to the extraneous light quantity storage value. Perform processing. Here, the CPU 61 functions as an external light amount determination unit. If it is determined in step S12 that the extraneous light amount has decreased with respect to the extraneous light amount stored value, the process proceeds to step S13, and the light emission amount of each LED of the irradiation device 1 is reduced by the same amount as the decrease rate, for example. Perform processing. On the other hand, when it is determined in step S12 that the extraneous light amount has increased with respect to the extraneous light amount stored value, the process proceeds to step S14,
For example, each LED of the irradiation device 1 is equal to the increased rate.
Is performed to increase the amount of light emission. Here, the CPU 61
Functions as light amount correction means. Step S13 above
Alternatively, through step S14, the apparent brightness of the reflected light 1b is corrected to a desired value regardless of the brightness of the surrounding environment. After step S13 or step S14, the process returns to step S11. When the same processing as described above is performed again in step S11, it is determined that the extraneous light amount and the extraneous light amount stored value are the same this time (however, there is no change in the brightness of the surrounding environment from the previous step S11). In this case, the process proceeds to step S15.

In step S15, all the LEDs of the irradiation device 1 whose light amount has been adjusted as described above are caused to emit light,
A process for maintaining the light emitting state for a predetermined time is performed. this is,
This is for adjusting the adjusted light amount to the eyes of the operator.

Thereafter, the worker matches the irradiated portion 4 of the marking light 1a with the mark 3a of the body 3 (the mark 3a and the marking light 1a match).
When the matching-time light amount storage switch 73 is turned on by a pressing operation after performing the work, the matching-time light amount storage switch 73 is set to “o” in the subsequent step S16.
As a result of performing the process of determining whether the state is “n”,
It is determined that the state is “on”, and the process proceeds to step S17.

In step S17, the light amount of the reflected light 1b received by the light receiving sensor 2 in a state where the mark 3a and the marking light 1a coincide with each other is determined as the coincidence light amount.
Then, the process proceeds to step S18. It should be noted that the light quantity at the time of coincidence is the light quantity at the time of coincidence, which is compared with the light quantity of each element light in step S5. Here, the light quantity at the time of coincidence is the mark 3a and the marking light 1
When the mark 3a and the marking light 1a coincide with each other when the marking light 1a is radiated from the irradiation device 1 with an output such that the reflected light 1b becomes the set light amount when a does not coincide with the light receiving sensor 2, Reflected light 1b received by
Note that this is the amount of light. After storing the light quantity at the time of coincidence, the body 3 is positioned so that the mark 3a and the illuminated portion 4 coincide with each other, so that the light receiving sensor 2 receives the reflected light 1b having the same light quantity as the light quantity at the coincidence. It is detected that the irradiation portion 4 of the marking light matches. That is, at this time, the CPU 61 functions as a coincidence detecting unit.

<Setting Light Amount in Coincidence State> Here, if the mark 3a and the marking light 1a coincide with each other, the reflected light 1b may be too dazzling and difficult to see. In this case, the amount of reflected light 1b at the time of coincidence may be set to a desired value, as described below. First, the operator presses the notification light quantity setting switch 74 to set “o”.
n "state. In this state, in step S18, when a process of determining whether or not the notification light amount setting switch 74 is in the “on” state is performed, it is determined that the notification light amount setting switch 74 is in the “on” state, and the process proceeds to step S19. In this case,
The display unit 71 displays a notification light amount setting screen (not shown) based on the “on” operation of the notification light amount setting switch 74. In step S19, the operator appropriately adjusts each of the adjustment keys 76a, 76b, 77a, 77b, 78a, 78b.
By pressing, the amount of light (the amount of each of the red, green, and blue component lights) changed at the time of matching is set as a notification light amount to the operator's preference (for example, easy-to-see brightness (light amount) and color), and A process of storing the data of the notification light amount in the RAM 63 is performed. In the above, the light amount (reporting light amount) of the reflected light 1b that is changed when they match is set. After this setting, when the body 3 is positioned and the mark 3a and the irradiated portion 4 are matched, the light amount is switched from the normal set light amount to the notification light amount set here. That is, at this time, C
The PU 61 functions as a notification unit, and the irradiation state of the marking light 1a is changed by bringing the state into the coincidence state. Therefore, for example, if the notification light amount is set to a value that is not dazzling (smaller) than the light amount at the time of matching, the reflected light 1b can be prevented from being dazzling when they match.
Alternatively, for example, if the notification light amount is set to a color different from that of the reflected light 1b in the case of the normal set light amount, the color is changed when they match, so that the operator can easily recognize that they match.

In the following step S20, a process is performed to determine whether or not the reset switch 75 is in the "on" state. If it is determined that the reset switch 75 is not in the "on" state, the process returns to step S18. On the other hand, in step S20,
If it is determined to be in the “on” state, step S
Return to 2. That is, when the operator presses the reset switch 75, the coincidence light amount storage switch 73 and the coincidence light amount setting switch 74 are turned off, and the process returns to step S2.

Subsequently, when the same processing as described above is performed again in steps S2 to S4, the current step S4

In the above, the set light quantity is changed to a desired value for each of the element lights (red, green, blue) (the set color is also changed to a desired value), and the setting after this change is changed. The light quantity data (also the set color data) is stored in RAM
63. Here, the CPU 61 functions as a set light amount changing unit and a set color changing unit. After this change, in steps S4 to S8, step S9, and step S10, processing for adjusting to the new set light amount and color set here is performed (however, the mark 3a and the irradiated portion are not changed). 4 is not in agreement).

<Correction of Marking Light> Step S3
In the case of 3 or less, based on the pressing operation of the light color correction switch 79, a process of correcting the marking light 1a to a color having a high reflectance from the body material 3 is performed as described below.

First, in step S33, a process is performed to determine whether or not the light color correction switch 79 is in the "on" state. If it is determined that the light color correction switch 79 is in the "on" state, the process proceeds to step S34. I do. In step S34, a process of comparing the output level of each LED (red, green, blue) of the irradiation device 1 with the light amount of each element light (red, green, blue) included in the reflected light 1b, A process of determining a color having a high reflectance from the body fabric 3 based on an LED (for example, any of red, green, and blue) that emits a color determined to have a high reflectance from the body fabric 3 as a result of this process. One) to increase the light emission amount (for example, 10%), and the reflected light 1b after this processing.
Is stored in the RAM 63 as data on the amount of light (data for each element light) contained in the RAM 63. Here, the color having a high reflectance is, for example, red when the body cloth 3 is strong red, green when the body cloth 3 is strong green, and blue when the body cloth 3 is strong green. If strong, blue. In the above, the marking light 1a
Is corrected to a color having a high reflectance from the body material 3. Here, the CPU 61 functions as light color correction means.

Further, after step S34, the process proceeds to step S35. On the other hand, if it is determined in step S33 that the light color correction switch 79 is not in the “on” state, the process proceeds to step S35 without performing the process of correcting the color of the marking light 1a. In step S35, a process is performed to determine whether or not the reset switch 75 is in the “on” state. If it is determined that the reset switch 75 is not in the “on” state, the process returns to step S24. On the other hand, if it is determined in step S35 that the state is the “on” state, the process returns to step S2. That is, when the operator presses the reset switch 75, the set light amount setting switch 72 is set to the “off” state, and the step S
