Description

  The present invention relates to a sewing apparatus that sews a workpiece, and more particularly to a sewing apparatus that transmits and receives information related to a sewing operation, an information communication system thereof, and a control program for the sewing apparatus.

  The sewing device includes, for example, a sewing needle for sewing a workpiece (cloth etc.), a cloth holding member including a so-called cloth presser or embroidery frame for pressing or holding the workpiece during sewing, and a button in a boring machine Depending on the user's sewing mode and sewing device specifications, such as cutters used to form holes, hammers that come into contact with the cutters to take a cutting reaction force with the cutters, and thread trimming cutters that cut the sewing thread after sewing is complete , There are things that are used by replacing them with suitable ones (sometimes called gauges). In addition to such replacement according to the sewing mode and specifications, a balance for adjusting the tension by hooking the upper thread and the upper thread that sags when the sewing needle penetrates below the workpiece is hooked. There are parts such as a hook tip of a rotary hook, more broadly, a motor that drives various operating members, and the like, which need to be replaced at a predetermined time because their life deteriorates with use.

  As an example of such a sewing apparatus, there is one described in Patent Document 1, for example. In this prior art, there is a piggy hole sewing machine which has a cutter and a hammer for forming a button hole as the replacement part, and sews a piggy hole stitch composed of a piglet portion and a linear foot portion continuous therewith. It is disclosed.

  In the above prior art, the above-described replacement part is usually detachably attached to the sewing apparatus main body for the convenience of replacement. Since these are structures that can be attached and detached by the user relatively freely (freely) on the sewing device body side, the user can perform sewing using incorrect sewing conditions and sewing programs that are not necessarily optimal for the attached parts. There is a possibility that it is performed or a part different from the part that should be originally attached is mistakenly attached and used. In such a case, the original performance of the sewing apparatus cannot be exhibited, leading to poor sewing and a reduction in sewing work efficiency, and there is a possibility that the durability of the sewing apparatus main body is partially lowered or breaks down.

  In order to prevent this, for example, it is conceivable that a serviceman regularly visits a sewing factory equipped with a large number of sewing devices to perform a check. In this case, one combination of parts is used for all sewing devices. One has to be checked, which is a very complicated and time-consuming work. In addition, the target sewing device must be stopped at the time of checking, which leads to a decrease in productivity.

  The object of the present invention is to easily perform compatibility checks to ensure that the original performance is exhibited even when parts are replaced, and that the occurrence of sewing defects and the reduction in work efficiency and durability are prevented. An object of the present invention is to provide a sewing device that can be used, an information communication system for the sewing device, and a control program for the sewing device.

The antenna (device-side antenna unit) 40 that transmits and receives signals by radio communication using a high frequency such as a band, and information (wireless tag information) of the IC circuit unit 100 of the wireless tag T is accessed via the antenna 40 ( Information for reading and writing) and access information for processing signals read from the IC circuit unit 100 of the RFID tag T to read information and accessing the IC circuit unit 100 of the RFID tag T A tag reader including a signal processing circuit 52 that also functions as an access information generation unit for generating a high-frequency circuit 51 and a signal processing circuit 52 And a control circuit 60 for controlling the writer 50 overall operation.

  The control circuit 60 is a so-called microcomputer, and although not shown in detail, is composed of a central processing unit such as a CPU, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and is temporarily stored in the RAM. The signal processing is performed according to a program stored in advance in the ROM while using the function. The control circuit 60 is connected to the control device 17 of the sewing apparatus M via the input / output interface 61 so that information can be exchanged with the control device 17.

  The high-frequency circuit 51 includes a transmission unit 53 that transmits a signal to the wireless tag T via the antenna 40, a reception unit 54 that receives a reflected wave from the wireless tag T received by the antenna 40, and a directional coupler 55. It consists of.

  The transmission unit 53 is a crystal resonator 56 that functions as a carrier wave generation unit that generates a carrier wave for accessing (reading and writing) the RFID tag information of the IC circuit unit 100 of the RFID tag T, and a PLL (Phase Locked Loop). 57, and a VCO (Voltage Controlled Oscillator) 58 and a carrier wave generated by the carrier wave generator based on a signal supplied from the signal processing circuit 52 (for example, amplitude modulation based on a “TX-ASK” signal) A first mixer 71 functioning as a carrier wave modulation unit, and a first amplifier 72 functioning as a modulation wave amplification unit that amplifies the modulated wave modulated by the first mixer 71. The carrier wave generated by the carrier wave generator preferably uses a UHF band frequency, and the output of the first amplifier 72 is transmitted to the antenna 40 via the directional coupler 55 to be a wireless tag. It is supplied to the IC circuit unit 100 of T.

  The receiving unit 54 includes a second mixer 73 that multiplies the reflected wave from the radio tag T received by the antenna 40 and the carrier wave generated by the carrier wave generating unit, and the output of the second mixer 73 is a bandpass filter. A phase difference of 90 ° after being generated by the second amplifier 76, which is input via 74 and amplified and supplied to the first limiter 75, and the reflected wave from the radio tag T received by the antenna 40 and the carrier wave generator. A third mixer 77 that multiplies the shifted carrier wave, and a third amplifier 80 that inputs the output of the third mixer 77 through a band-pass filter 78 and amplifies and supplies the amplified signal to the second limiter 79. . The signal “RXS-I” output from the first limiter 75 and the signal “RXS-Q” output from the second limiter 79 are input to the signal processing circuit 52 and processed.

  At this time, the outputs of the first amplifier 76 and the third amplifier 80 are also input to an RSSI (Received Signal Strength Indicator) 81 so that a signal “RSSI” indicating the strength of those signals is input to the signal processing circuit 52. It has become. In this way, in the tag reader / writer 50 of the present embodiment, the reflected wave from the wireless tag T is demodulated by IQ orthogonal demodulation.

  The RFID tag information stored in the RFID tag T configured as described above is stored in the tag reader / device when each component is attached to (or approaches) the sewing device body M1 side (or the member side attached to the sewing device body M1). The information is read by the writer 50 and the read information is output to the control device 17 of the sewing device M.

  FIG. 7 is a flowchart showing a control procedure executed by the control device 17 of the sewing apparatus M based on the read information.

  In FIG. 7, first, in step S10, the RFID tag information of the RFID tag T read out by the reader / writer 50 as described above (for example, type identification information indicating the type of each component, or an individual of the same type attached to each individual). Identification information, etc.).

  Thereafter, in step S20, the set values of the sewing conditions “stitch length F”, “stitch pitch”, and “number of stitches of stitches DE” set by the keys 15d to f of the operation panel 15 are taken in and identified.

  In step S30, referring to the predetermined combination suitability reference table stored in advance in the ROM 17B, the cutter 6, the hammer 7 and the cloth presser 32 (hereinafter referred to as appropriate) identified from the RFID tag information recognized in step S10. And the combinations of the “stitch length F”, “stitch pitch”, and “eyelet part DE stitch number” recognized in step S20 are appropriate. Determine if it exists.

  8 and 9 show an example of the combination suitability reference table.

  FIG. 8 shows an example of the suitability of the combination of the cloth presser 32 and the cutter 6 according to the size (L, M, S), and FIG. 9 shows the size (L, M, S) of the hammer 7 and the cutter 6. S) An example of suitability of another combination is shown.

  In FIG. 8, only a relatively small S size cutter 6 (see FIG. 11A) is suitable for the relatively small S size cloth presser 32 (see FIG. 10A). Therefore, the cutter 6 having a large L size (see FIG. 11C) and an intermediate M size (see FIG. 11B) is not suitable. Further, the S size and M size cutters 6 are suitable for the M size cloth presser 32 (see FIG. 10B), and the L size cutter 6 is not suitable. On the other hand, any of the S size, M size, and L size cutters 6 is suitable for the L size cloth presser 32 (see FIG. 10C). To summarize the above, in the three-stage size notation of S, M, and L, the case where the size of the cloth presser 32 is the same or larger than that of the cutter 6 is suitable and the size of the cloth presser 32 is small. Does not fit. This is because if the cloth presser 32 is relatively small in size, the cutter 6 interferes with the cloth presser 32 when forming the eyelet hole DH.

  The same applies to FIG. 9. In the three-stage size notation of S, M, and L, the case where the size of the hammer 7 is the same or larger than that of the cutter 6 is suitable, and the size of the hammer 7 is small. Is incompatible.

  Returning to FIG. 7, the determination in step S30 is performed as described above. If the combination is appropriate, the determination is satisfied, and the process proceeds to step S40.

  In step S40, a display control signal for causing the display unit 15g of the operation panel 15 to display appropriateness is generated and output via the output interface 17E. FIG. 12 is a diagram illustrating an example of a screen display displayed on the display unit 15g at this time. When step S40 ends, the process proceeds to step S50.

  In step S50, the values stored in the operation panel 15 so far, the wireless tag information (type identification information) by the tag reader / writer 50, and the conformity determination result thereof are stored in the program storage area of the ROM 17B. The optimum one is selected and read out from a plurality of eyelet stitch control programs (specifically, the CPU 17A generates a selection signal for selecting the control program as a sewing control signal and outputs it to the ROM 17B. A control program corresponding to this is read out). Correspondingly, the most suitable one for the current sewing is appropriately selected from a plurality of stitch data (stitch condition data) stored in the stitch data storage area of the ROM 17B described above (in detail, The CPU 17A generates a selection signal for selecting the stitch data as a sewing control signal and outputs the selection signal to the ROM 17B, and the stitch data corresponding to the selection signal is read out from the ROM 17B. The sewing data (stitch data) in the present eyelet stitching is created. In this stitch data, for example, in order to determine the needle drop position of the outer needle with respect to the inner needle for each of a predetermined number of needles (17 needles in this example), the X-direction drive motor 28, the Y-direction drive motor 30, and θ The number of driving pulses of each direction driving motor 22 is set.

  FIG. 13 is a flowchart showing a detailed procedure for creating sewing data in step S50. As shown in FIG. 13, first, stitch data for the first stitch of the eyelet stitch is created in step S51, and this stitch data is newly stored in, for example, the data memory of the RAM 17C. Further, in step S52, the stitch data for the second stitch is created. Stitch data is created and stored in the same manner, and thereafter, the third stitch and the fourth stitch are advanced in the same manner, and finally the stitch data of the N + 1 stitch that becomes the predetermined number of stitches N + 1 (N = 17 in this example) is created. (Step S53) and this procedure is terminated.

  FIG. 14 is an explanatory diagram showing an example of the contents of the stitch data of the eyelet stitching created as described above, and FIG. 15 is a detailed configuration of the stitches of the eyelet stitching formed on the work cloth. FIG.

  14 and 15, in this example, among the 17 stitches, the first stitch 1N to the fifth stitch 5N are stitch data for the over stitching of the right foot FR, and the sixth stitch 6N to the thirteenth stitch 13N are the eyelet portions. This is stitch data for the DE stitching, and the 14th stitch 14N to 17th stitch 17N are stitch data for the stitching of the left foot FL.

  In FIG. 15, for example, the inner needle of the first stitch 1N is indicated by <1>, and the outer needle of the first stitch is indicated by (1). Further, as the movement direction of the feed base 8, the leftward movement of the feed base 8 in the X direction is defined as the “+” side, and the forward movement in the Y direction is defined as the “+” side. .

  Returning to FIG. 7, when the sewing data creation in step S50 as described above is completed, the process proceeds to step S60, where a display control signal having the same content as that shown in FIG. 14 is generated and output via the output interface 17E. Then, the display corresponding to the display unit 15g of the operation panel 15 is performed.

  Thereafter, the process proceeds to step S70, where an operation signal from the start / stop pedal 16 is identified, and it is determined whether the pedal 16 is depressed (turned on). When the determination is satisfied, the process proceeds to step S80, where the stitch data stored in the data memory of the RAM 17C is read for each stitch, and each stitch data is read out from the program storage area of the ROM 17B which has been read out. While being applied to the sewing control program, corresponding drive control signals as sewing control signals are generated and output to the motors 20, 22, 28, 30 and the electromagnetic switching valve 25, and each is driven to correspond to the sewing device M. Perform the operation and execute the sewing process. That is, as shown in FIG. 15, the eyelet stitching made up of the right foot portion FR, the eyelet portion DE, and the left foot portion FL is performed by moving the first stitch 1N to the 17th stitch 17N. The eye DN is sewn.

  On the other hand, when it is determined in the previous step S30 that the combination is not appropriate, the process proceeds to step S90. In step S90, it is determined from the RFID tag information recognized in step S10 whether the attached parts 6, 7, and 32 are genuine products of the manufacturer of the sewing apparatus M. When it is recognized that all the RFID tag information of the parts 6, 7, and 32 are genuine products, the process proceeds to step S100.

  In step S100, referring to a predetermined combination suitability reference table stored in advance in the ROM 17B, the nonconformity can be avoided only by changing the set value by the operation panel 15 without replacing the parts 6, 7, and 32. (Detailed explanation is omitted, but information on the presence or absence of such avoidability is also incorporated in the suitability reference table).

  If the change can be avoided only by changing the setting, the determination in step S100 is satisfied, and the process proceeds to step S110. A display control signal for clearly indicating a measure for performing the avoidance is generated and output via the output interface 17E. Output to the operation panel 15. FIG. 16 is a diagram illustrating an example of a screen display displayed on the display unit 15g at this time. In FIG. 16, if only the setting of the stitch length F is changed from 30 mm to 20 mm among the current settings (without changing the other settings and without replacing the parts 6, 7, and 32). This indicates that proper sewing is possible, and a “Yes” button that agrees to this setting change and a “No” button that disagrees are also displayed.

  When the operator who has seen this display has performed an operation of accepting the setting change (clicking the “Yes” button), the determination in the next step S120 is satisfied, and the changed set value is returned to step S20. And repeat the same procedure. When the operator performs an operation not to approve the setting change (clicks the “No” button), the determination in the next step S120 is not satisfied, and the process proceeds to step S130.

  In step S130, referring to a predetermined combination suitability reference table stored in advance in the ROM 17B, the nonconformity does not change the set value and executes a preset operation restriction on sewing on the sewing apparatus M side. Whether or not it can be avoided is determined (detailed explanation is omitted, but information on the presence or absence of such avoidability is also incorporated in the suitability reference table).

  If it cannot be avoided only by the operation restriction, the process returns to step S110 to repeat the same procedure in order to notify the operator that the setting should be changed. If it can be avoided only by the above-described operation restriction, the determination in step S130 is satisfied, the process proceeds to step S140, and a display control signal for clearly indicating a measure for performing the avoidance is generated and the operation panel is output via the output interface 17E. 15 is output. FIG. 17 is a diagram illustrating an example of a screen display displayed on the display unit 15g at this time. In FIG. 17, among the current settings, it is shown in advance that the setting of the stitch length F is forcibly limited to 30 mm → 20 mm, and a “Yes” button for accepting this operation restriction is disapproved. "No" button is also displayed.

  When the operator who sees this display performs an operation not to understand the operation restriction (clicks the “No” button), the determination in step S150 is not satisfied, and the same display is performed by returning to step S140 to perform the operation. If an operation is performed assuming that the restriction is accepted (the “Yes” button is clicked), the determination in step S150 is satisfied and the process proceeds to step S50, and the operation restriction is made from the program storage area of the ROM 17B as described above. Select and read the sewing program (operation restriction program) under operation restriction corresponding to. Correspondingly, a corresponding one of a plurality of stitch data stored in the stitch data storage area is selected as appropriate, and eyelet stitch sewing data under the current operation restriction is created. That is, in the above-described example, sewing data with correction such that the stitch length F = 20 mm is created, and thereafter, the same steps S60, S70, and S80 as described above are executed.

  If the non-conformity is not avoided only by the setting change in step S100, this determination is not satisfied and the process moves to step S160, and a display control signal is generated to clearly indicate that component replacement should be performed to avoid the non-conformance. Then, the data is output to the operation panel 15 via the output interface 17E. FIG. 18 is a diagram illustrating an example of a screen display displayed on the display unit 15g at this time.

  FIG. 18 shows that it is impossible to avoid the nonconformity only by changing the current setting, and that proper sewing can be performed once the power is turned off and the cutter 6 is changed from the L size to the S size. In addition, a “Yes” button for agreeing to the setting change and a “No” button for disagreeing are also displayed.

  If the operator who sees this display has performed an operation to accept the setting change (clicks the “Yes” button), the determination in the next step S170 is satisfied, and the process proceeds to step S180 to turn on the power of the entire sewing apparatus M. Is turned OFF, and this flow ends. The operator can replace parts by turning off the power. If the operator performs an operation not to accept the setting change (clicks the “No” button), the determination in step S170 is not satisfied, and the process proceeds to step S190.

  In step S190, referring to a predetermined combination suitability reference table stored in advance in the ROM 17B, the non-conformity is not assumed as an attachment target without replacing any of the parts 6, 7, and 32. It is determined whether it can be avoided only by executing the sewing operation restriction on the sewing device M side set in advance (detailed explanation is omitted, but information on the existence of such avoidability is also included) Incorporated in the adequacy lookup table).

  If it cannot be avoided only by the operation restriction, the process returns to step S160 and the same procedure is repeated to notify the operator that the parts should be replaced. If it can be avoided only by the above-described operation restriction, the determination in step S190 is satisfied, and the process proceeds to step S140. Similarly to the above, a display control signal is generated to clearly indicate a measure for avoiding the operation, and the operation panel 15 The same procedure is performed thereafter.

  On the other hand, when it is recognized in step S90 that any one of the RFID tags information of the parts 6, 7, and 32 is not genuine, or when the RFID tag information itself cannot be read by the tag reader / writer 50 ( If there is no recognition information), the determination at step S90 is not satisfied, and the routine goes to step S200.

  In step S200, as in the case of step S100, while referring to the predetermined combination suitability reference table stored in advance in the ROM 17B, the non-conformity related to the non-genuine product is not replaced with the parts 6, 7, and 32 without operating the operation panel. It is determined whether or not it can be avoided only by changing the set value by 15 (detailed explanation is omitted, but information on the presence or absence of such avoidability is also incorporated in the suitability reference table).

  If the change can be avoided only by changing the setting, the determination in step S200 is satisfied, and the process proceeds to step S210. Similar to step S110 described above, a display control signal is generated for clearly indicating a measure for the avoidance. To the operation panel 15 via the output interface 17E. FIG. 19 is a diagram illustrating an example of a screen display displayed on the display unit 15g at this time. In FIG. 19, if the RFID tag information of the cutter 6 cannot be recognized and it is a non-genuine product, and only the setting of the stitch length F is changed from 30 mm to 20 mm among the current settings, (other settings are changed. (Without replacing the hammer 7 and the cloth presser 32), it is shown that the minimum necessary sewing is possible, and the “Yes” button that accepts this setting change and the “No” button that does not agree It is also displayed.

  When the operator who has seen this display has performed an operation for accepting the setting change (clicking the “Yes” button), the determination in the next step S220 is satisfied, and the process returns to step S20 to change the changed setting value. And repeat the same procedure. When the operator performs an operation not to approve the setting change (clicks the “No” button), the determination in the next step S220 is not satisfied, and the process proceeds to step S230.

  In step S230, referring to a predetermined combination suitability reference table stored in advance in the ROM 17B, the non-conformity is mounted (not recognized) without changing the set value (cutter in this example). 6) is determined as to whether or not it can be avoided under the condition that the operator confirms with the naked eye (detailed explanation is omitted, but information on the presence / absence of such avoidance is also incorporated in the above-described suitability reference table. ing).

  When it is possible to avoid by the confirmation on the operator side, the determination in step S230 is satisfied and the process proceeds to step S240, and a display control signal for clearly indicating the content of confirmation to be performed on the operator side (necessary for sewing, etc.) Corresponding to a signal for displaying a guidance of a necessary preparation operation), and outputs it to the operation panel 15 via the output interface 17E. FIG. 20 is a diagram illustrating an example of a screen display displayed on the display unit 15g at this time. FIG. 20 shows a screen for requesting to confirm whether or not the cutter 6 that is not currently recognized interferes with the cloth presser 32 when the eyelet DH of the cutter 6 is formed. In addition, a “Yes” button for accepting the confirmation request and a “No” button for disagreeing are also displayed.

  If the operator who sees the display performs an operation not to accept the confirmation request (clicks the “No” button), the determination in step S250 is not satisfied, and the same display is performed by returning to step S240 to confirm. If an operation is performed that the request is accepted ("Yes" button is clicked), the determination in step S250 is satisfied, the process proceeds to step S50, and the above-described interference is not caused by the confirmation. To create sewing data. Thereafter, the same steps S60, S70 and S80 as described above are executed.

  If it cannot be avoided by the confirmation on the operator side, the determination in step S230 is not satisfied, and the routine goes to step S260.

  In step S260, referring to a predetermined combination suitability reference table stored in the ROM 17B in advance, the non-conformity regarding the non-genuine product does not change the setting or replace the part (cutter 6 in the above example), and the sewing device It is determined whether or not it can be avoided only by executing preset sewing operation restrictions for non-genuine parts on the M side (detailed explanation is omitted, but whether such avoidability exists) Is also incorporated in the suitability reference table).

  If it cannot be avoided only by the operation restriction, the process returns to step S160 and the same procedure is repeated to notify the operator that the parts should be replaced. If it can be avoided only by the above-described operation restriction, the determination in step S260 is satisfied, and the process proceeds to step S140. Similarly to the above, a display control signal for clearly indicating a measure for the avoidance is generated and the operation panel 15 is generated. The same procedure is performed thereafter.

  In the above, the tag reader / writer 50 constitutes reading means for reading information relating to the detachable parts described in each claim. Further, the control device 17 of the sewing apparatus M constitutes a second signal generating means for generating a corresponding sewing control signal or display control signal in accordance with the information read by the reading means.

  The operational effects of the present embodiment described above will be described below.

  That is, in the sewing apparatus M of the present embodiment, a wireless tag storing information related to the part is attached to each of the parts 6, 7, and 32. When the parts 6, 7, and 32 are attached to the sewing apparatus main body M1 (or approached to be attached), the tag reader / writer 50 is associated with the corresponding parts 6, 7, and 32 from each wireless tag T. The identification information or the individual identification information is read, which is fetched in step S10 executed by the control device 17 of the sewing apparatus M, and the stitch length F and stitches set and input on the parts 6, 7, 32 and the operation panel 15 are input. Depending on the combination of the pitch and the setting value of the number of stitches of the eyelet part DE, the corresponding sewing control signals (sewing program / sewing data selection signal and operation restriction program selection signal in step S50, drive control in step S80) Signal), a display control signal (a signal indicating that the combination in step S40 is appropriate), and a signal for displaying the contents of the sewing data in step S60. No., a signal for displaying the setting change recommendation in step S110 and step S210, a signal for notifying the operation restriction in step 140, a signal for displaying the component replacement recommendation in step S160, and the operator side confirmation in step S240 A signal for displaying the request). In step S50, the optimum normal control program and sewing data corresponding to the set values of the parts 6, 7, 32 and the operation panel 15 are selected, final sewing data is created, and sewing processing is performed in step S80. Accordingly, it is possible to reliably realize appropriate sewing conditions suitable for the sewing mode and the specifications of the sewing apparatus M based on the types of the parts 6, 7, and 32. As a result, the original performance of the sewing device M can be reliably exhibited, and the sewing work efficiency can be improved.

  If the parts 6, 7, and 32 are not preliminarily assumed as attachment targets (non-genuine products or the same manufacturer but not the target), the process from step S130, step S190, and step S260 to step S50. A control program and sewing data under an operation restriction that applies a predetermined operation restriction for such a part is selected, final sewing data is created, and a sewing process is performed in step S80. As a result, for example, when non-genuine parts are used, sewing does not become impossible, and it prevents the occurrence of malfunctions due to a decrease in durability, while preventing poor sewing and providing the minimum necessary sewing performance. Can be secured. As a result, it is possible to improve the sewing work efficiency as compared with at least the case where sewing is impossible.

  In the above, compared with the conventional method in which a service person checks manually one by one, the check operation can be performed in a very short time and easily by transmitting a large amount of information using wireless communication and automatic judgment / display. . Further, since it is not necessary to stop the sewing apparatus M at the time of checking, the productivity can be improved.

  In particular, the parts 6, 7, and 32 are not preliminarily assumed as attachment targets (non-genuine products or the same manufacturer but are not covered), and when performing the above operation restriction, before adding the operation restriction, In step S140, a display prompting confirmation input as to whether or not the operation restriction may be added is performed. Thereby, thereafter, the operation can be restricted and the operator can be surely recognized in advance that it is difficult to achieve the original performance. If the above-described parts 6, 7, and 32 are not supposed to be attached in advance, the original performance of the sewing apparatus M is displayed by causing the operator to display that in step S210, step S240, or the like. Can recognize that it is difficult to come out. As a result, it is possible to avoid as much as possible an unreasonable use that causes a failure due to poor sewing or a decrease in durability. This also prevents a reduction in sewing work efficiency.

  Further, in step S240, guidance is displayed for the contents of other necessary preparation work (confirmation work to be performed on the operator side) regarding sewing using the part. As a result, the operator can be surely realized by prompting the operator with sewing conditions suitable for the sewing mode and the specifications of the sewing apparatus M, so that the original performance of the sewing apparatus can be reliably exhibited and the sewing work efficiency can be improved. Can be planned.

  In this example, the RAM 200B, in the same way as the RAM 17C of the first embodiment, stores the stitch data selected and read from the plurality of reference stitch data based on the setting on the operation panel 15 (details will be described later). Various memories, buffers, and the like including a data memory for storing data to be used are provided.

  The most significant feature of the present embodiment is that the same control procedure as that executed by the control device 17 of the sewing device M in the first embodiment is unified for the sewing device M ′ targeted by the central control device 200. Is to do.

  FIG. 22 is a flowchart showing a control procedure executed by the central control device 200 based on information read by the tag reader / writer 50 ′, similarly to the control device 17 of the sewing device M of the first embodiment. Since all the procedures are the same as or similar to the control procedures of the control device 17 already described with reference to FIG. 7, the step numbers in FIG. Or, a simplified description will be given. This flow is executed individually for each sewing apparatus M ′.

  In FIG. 22, first, in step S10 ′, the RFID tag information of the tag T related to the component P radio of the target sewing apparatus M ′ read out by the tag reader / writer 50 ′ is taken into the CPU 200A via the I / O 200D and identified, and then in step S20. 'Is the set value of the sewing conditions "stitch length F", "stitch pitch", and "number of stitches DE stitch" set by the keys 15d to f (see Fig. 4) described above on the operation panel 15 of the sewing device M'. Are taken and identified in the same way. Then, with respect to the component P identified from the wireless tag information recognized in step S10 ′ while referring to the predetermined combination suitability reference table in step S30, and the set value recognized in step S20 ′, the mutual combination is appropriate. The CPU 200A determines whether there is any.

  If the combination is appropriate, the process moves to step S40 ′, a display control signal for displaying the appropriateness on the display unit 15g of the operation panel 15 is generated, and is sent to the display device 210 via the I / O 200D. Output.

  Thereafter, in step S50 ′, the program storage area of the above-described ROM 200C is set according to the set value by the operation panel 15 of the target sewing apparatus M ′, the wireless tag information by the tag reader / writer 50 ′, and the compatibility determination result. An optimum one of a plurality of eyelet stitching control programs set and stored in advance is selected and read (in detail, the CPU 200A generates a selection signal for selecting the control program as a sewing control signal and stores it in the ROM 200C. And a control program corresponding to this is read from the ROM 200C). Correspondingly, the most suitable one for the current sewing is appropriately selected from a plurality of stitch data (stitch condition data) stored in the stitch data storage area of the ROM 200C described above (in detail, The CPU 200A generates a selection signal for selecting the stitch data as a sewing control signal and outputs the selection signal to the ROM 200C, and the stitch data corresponding to the selection signal is read from the ROM 200C. The sewing data (stitch data) in the present eyelet stitching is created. At that time, as described with reference to FIG. 13 in the first embodiment, for example, stitch data is created for each stitch, and the stitch data is newly stored in the data memory of the RAM 200B each time, for example. To go.

  When the creation of the sewing data in step S50 ′ is completed, the process proceeds to step S60 ′, where a display control signal for the contents of the created sewing data is generated and output via the I / O 200D to display corresponding to the display device 210. . Thereafter, in step S70 ′, an operation signal from the start / stop pedal 16 (see FIG. 3 described above) of each sewing apparatus M ′ is identified, and it is determined whether or not the pedal 16 is depressed. If the determination is satisfied, the stitch data stored in the data memory of the RAM 200B is read for each stitch at step S80 ', and each stitch data is read from the read stitch hole stitch selected from the program storage area of the ROM 200C. While being applied to the control program, drive control signals to the motors 20, 22, 28, 30 and the electromagnetic switching valve 25 of the target sewing device M ′ are generated and output via the I / O 200D and the control device 17 of the sewing device M ′. Then, each is driven to perform an operation corresponding to the sewing apparatus M ′, and the sewing process is executed.

  On the other hand, if it is determined in the previous step S30 ′ that the combination is not appropriate, the process proceeds to step S90 ′, and the attached (or approached) part P is identified as the target sewing device from the RFID tag information recognized in step S10 ′. It is determined whether it is a genuine product of the manufacturer of M ′.

  When it is recognized that the RFID tag information of the part P is a genuine product, the process proceeds to step S100 ′, and the above-mentioned nonconformity is detected by the target sewing apparatus M ′ while referring to a predetermined combination suitability reference table stored in the ROM 200C in advance. It is determined whether or not it can be avoided only by changing the set value through the operation panel 15.

  If it can be avoided only by changing the setting, the process proceeds to step S110 ′, where a display control signal for specifying a measure for the avoidance is generated and output to the display device 210 via the I / O 200D. When an operator who has seen this display (the person in charge of operation / control of the central control device 200, the same applies hereinafter) performs an operation to approve the setting change, the determination in the next step S120 ′ is satisfied, and the process proceeds to step S20 ′. Go back and repeat the same procedure. When the operator performs an operation not to approve the setting change, the determination at the next step S120 ′ is not satisfied, and the process proceeds to step S130 ′. In step S130 ', referring to a predetermined combination suitability reference table stored in advance in the ROM 200C, the non-conformity can be avoided only by executing a preset operation restriction on the sewing of the target sewing device M'. It is determined whether or not.

  If it cannot be avoided only by the operation restriction, the procedure returns to step S110 ′ to repeat the same procedure to notify the operator that the setting should be changed. If it can be avoided only by the above-described operation restriction, the process proceeds to step S140 ′, and a display control signal for clearly indicating a measure for the avoidance is generated and output to the display device 210 via the I / O 200D. When the operator who sees this display performs an operation that does not understand the operation restriction, the determination in step S150 ′ is not satisfied, and the same display is performed by returning to step S140, and the operation that the operation restriction is accepted is performed. If so, the determination at step S150 ′ is satisfied and the routine proceeds to step S50, and the sewing program under the operation restriction corresponding to the operation restriction (operation restriction program) is selected from the program storage area of the ROM 200C as described above. read out. Correspondingly, a corresponding one of a plurality of stitch data stored in the stitch data storage area is selected as appropriate, and eyelet stitch sewing data under the current operation restriction is created. Thereafter, the same steps S60 ′, S70 ′ and S80 ′ as those described above are executed.

  In step S100 ′, if non-conformity is not avoided only by changing the setting, the process proceeds to step S160 ′ to generate a display control signal for clearly indicating that component replacement should be performed in order to avoid the nonconformity. The data is output to the display device 210 via O200D. If the operator who sees this display performs an operation for accepting the setting change, the determination at the next step S170 ′ is satisfied, and the process proceeds to step S180 ′ to turn off the power of the entire sewing device M ′. End the flow. When the power is turned off, the parts P of the sewing device M ′ can be replaced. If the operator performs an operation not to approve the setting change, the process moves to step S190 ′, and the above-mentioned nonconformity is not assumed in advance as an attachment target of the sewing device body M′1 of the target sewing device M ′. It is determined whether it can be avoided only by executing the sewing operation restriction on the sewing apparatus M ′ side set in advance for the part.

  If it cannot be avoided only by the operation restriction, the process returns to step S160 ′ and the same procedure is repeated to notify the operator that the part P of the target sewing apparatus M ′ should be replaced. If it can be avoided only by the above-described operation restriction, the process proceeds to step S140 ′, and similarly to the above, a display control signal for clearly indicating a measure for the avoidance is generated and output to the display device 210, and thereafter the same procedure is performed. I do.

  On the other hand, when it is recognized in the previous step S90 ′ that the RFID tag information related to the part P of the target sewing apparatus M ′ is not a genuine product, or when the RFID tag information itself cannot be read by the tag reader / writer 50 ′ ( If there is no recognition information), the process proceeds to step S200, and whether or not the non-conformity relating to the non-genuine product can be avoided only by the change of the set value by the operation panel 15 of the target sewing apparatus M ′ as in step S100 ′. Determine.

  If it can be avoided only by changing the setting, the process proceeds to step S210 ′, and in the same way as in step S110 ′ described above, a display control signal for clearly indicating a measure for performing the avoidance is generated and the display device is displayed via the I / O 200D. Output to 210. When the operator who sees this display performs an operation for understanding the setting change, the determination in the next step S220 ′ is satisfied, and the process returns to step S20 ′ to identify the changed setting value. Repeat the procedure. If the operator performs an operation not to approve the setting change, the determination in the next step S220 ′ is not satisfied, and the process proceeds to step S230, where the nonconformity is mounted in the target sewing device M ′ (recognition). It is determined whether or not the component P can be avoided under the condition that the part P is confirmed with the naked eye.

  If it can be avoided by the above confirmation, the process proceeds to step S240 ′, and a display control signal for clearly indicating the content of confirmation to be performed on the operator side (corresponding to a signal for displaying guidance necessary for other work during sewing) Is output to the display device 210 via the I / O 200D. If the operator who sees this display performs an operation that does not accept the confirmation request, the determination at step S250 ′ is not satisfied, and the operation returns to step S240 ′ to perform the same display and the confirmation request is accepted. If the operation is performed, the process proceeds to step S50 ', and sewing data is generated in the same manner as described above on the assumption that the interference does not occur by the confirmation. Thereafter, the same steps S60 ′, S70 ′ and S80 ′ as those described above are executed.

  If it cannot be avoided by the confirmation from the operator side, the process proceeds to step S260 ′, and the non-genuine product nonconformity executes a sewing operation restriction set in advance for non-genuine product parts on the target sewing device M ′ side. It is determined whether it can be avoided only by things.

  If it cannot be avoided only by the operation restriction, the process returns to step S160 ′ and the same procedure is repeated to notify the operator that the parts should be replaced. If it can be avoided only by the above-described operation restriction, the determination in step S260 ′ is satisfied, and the process proceeds to step S140 ′. Similarly to the above, a display control signal is generated to clearly indicate a measure for the avoidance, and the display device The data is output to 210, and the same procedure is performed thereafter.

  In the above, the tag reader / writer 50 'constitutes a reading means for reading information related to the detachable component described in each claim. Further, the central control device 200 constitutes second signal generating means for generating a corresponding sewing control signal or display control signal in accordance with the information read by the reading means.

  Also in the present embodiment described above, it is possible to obtain substantially the same operational effects as those in the first embodiment.

  That is, in the information communication system S of the sewing apparatus of the present embodiment, a wireless tag T that stores information related to the part is attached to the part P of each sewing apparatus M ′. When the part P is attached to the corresponding sewing apparatus main body M′1 (or approached to be attached), the tag reader / writer 50 ′ uses the wireless tag T to identify the type identification information or individual identification related to the corresponding part P. The information is read, which is fetched in step S10 'executed by the central control device 200, and the stitch length F, stitch pitch, and eyelet portion DE that are set and input on the operation panel 15 of the part P and the target sewing device M'. Corresponding sewing control signals (sewing program / sewing data selection signal and operation restriction program selection signal in step S50 ', drive control signal in step S80', etc.) according to the combination of the set values of the number of stitches, Display control signals (a signal indicating that the combination of step S40 'is appropriate, a signal for displaying the contents of the sewing data in step S60', Step S110 ′ and step S210 ′ signal for displaying setting change recommendation, step 140 ′ signal for notifying operation limitation, step S160 ′ signal for displaying component replacement recommendation, operation of step S240 ′ A signal for displaying a confirmation request from the user side). In step S50 ', an optimum normal control program and sewing data corresponding to the set value of the part P of the target sewing apparatus M' and the operation panel 15 are selected, and final sewing data is created. In step S80 '. By performing the sewing process, it is possible to reliably realize appropriate sewing conditions suitable for the sewing mode and the specifications of the sewing apparatus M ′ based on the type of each part P. As a result, the original performance of the sewing apparatus M ′ can be reliably exhibited and the sewing work efficiency can be improved.

  Further, if the part P is not supposed to be attached in advance (non-genuine product or the same manufacturer but not subject), from step S130 ', step S190', step S260 'to step S50'. A control program and sewing data under an operation restriction that applies a predetermined operation restriction for such a part is selected, final sewing data is created, and the control device 17 of the target sewing apparatus M ′ is sent to the sewing machine M ′ in step S80 ′. Send and let the sewing process be performed. As a result, even if a non-genuine part P is used, for example, in the target sewing device M ′, sewing is not disabled, and it is possible to prevent poor sewing while preventing a failure due to a decrease in durability. The necessary minimum sewing performance can be secured. As a result, it is possible to improve the sewing work efficiency as compared with at least the case where sewing is impossible.

  In the above, compared with the conventional method in which a service person checks manually one by one, the check operation can be performed in a very short time and easily by transmitting a large amount of information using wireless communication and automatic judgment / display. . In addition, since it is not necessary to stop each target sewing device M ′ at the time of checking, productivity can be improved.

  Further, in particular, when the operation restriction is performed when the operation restriction is not made in advance as the part P (non-genuine product or the same manufacturer but not subject to the attachment), in step S140 ′, before the operation restriction is added. The display device 210 performs a confirmation display as to whether or not the operation restriction may be added. Thereby, thereafter, the operation can be restricted and the operator can be surely recognized in advance that it is difficult to achieve the original performance. Further, when the above-described component P is not assumed as an attachment target in advance, in step S210 ′, step S240 ′, etc., the display device 210 displays that effect, thereby allowing the operator to display the target sewing device M ′. It can be recognized that the original performance of is difficult to achieve. As a result, it is possible to avoid as much as possible an unreasonable use that causes a failure due to poor sewing or a decrease in durability. This also prevents a reduction in sewing work efficiency.

  Further, in step S240 ′, the contents of other necessary preparation work (confirmation work to be performed on the operator side) regarding sewing using the part P are displayed on the display device 210 as guidance. As a result, the operator can be surely realized the sewing conditions suitable for the sewing mode and specifications of the target sewing device M ′, so that the original performance of the sewing device can be reliably exhibited and the sewing work efficiency can be improved. Improvements can be made.

  In the second embodiment, various settings related to the eyelet stitching in each sewing device M ′ are performed by the operation panel 15 similar to that in the first embodiment. A common operation input means (for example, a keyboard, a mouse, etc.) may be provided (or may be different from this), and the above setting may be performed. In addition, various displays relating to each sewing device M ′ (for example, including an operation restriction warning display at step S140 ′, a recommendation / warning display at step S110 ′, step S160 ′, and step S210 ′) are displayed on the common display device 210. However, the present invention is not limited to this, and a display control signal may be output and displayed on the display unit 15g of each sewing apparatus M ′ as in the first embodiment.

  In the second embodiment, the central control device 200 creates final sewing data using the sewing program and stitch data stored in the ROM 200C according to the reading result of the tag reader / writer 50 '. Based on this, a drive control signal is generated as a sewing control signal to the motors 20, 22, 28, 30 and the electromagnetic switching valve 25 of the target sewing device M ′, and directly via the I / O 200D and the control device 17 of the sewing device M ′. Although it output to those actuators, it is not restricted to this.

  That is, the central control device 200 outputs a selection instruction signal as a sewing control signal to the control device 17 of the target sewing device M ′ in accordance with the reading and determination results, and each sewing device M as in the first embodiment. The CPU 17A of the control device 17 generates a selection signal for selecting a control program as a sewing control signal and outputs it to the ROM 17B. A control program corresponding to the selection signal is read from the ROM 17B, and the CPU 17A controls the sewing accordingly. A selection signal for selecting stitch data is generated as a signal and output to the ROM 17B. The stitch data is read out from the ROM 17B according to the selection signal, and the final stitch data is generated using the selected stitch data. You may make it produce | generate.

  The control program is held on the central control device 200 side, and the optimum program is selected and transmitted to the control device 17 of the target sewing device M ′, and is held on the control device 17 side accordingly. The stitch data may be selected, and final stitch data may be generated using the stitch data to generate a drive signal.

  The same applies to the case where the determinations in step S130 ', step S190', and step S260 'are satisfied and the sewing data under operation restriction is created in step S50'. That is, the central control device 200 creates final sewing data using the sewing program (operation restriction program) under the operation restriction of the ROM 200C and the stitch data corresponding thereto, and generates the drive control signal based on the sewing data. However, the central control device 200 outputs the operation restriction program selection instruction signal according to the reading and determination results, and the control device 17 selects the operation restriction program and responds to this. The stitch data may be selected and final stitch data may be generated using the selected stitch data to generate a drive signal. Further, the operation restriction program is held by the central control device 200 side, selected and transmitted to the control device 17 of the target sewing device M ′, and the corresponding stitch data is selected on the control device 17 side accordingly. Then, final stitch data may be generated using them to generate a drive signal.

  Further, in the first and second embodiments, when the operation is restricted on the sewing devices M and M ′ side, in step S140 or step S140 ′, a confirmation input as to whether or not the operation restriction may be performed is given to the operator. Although the display to perform is performed, it is not restricted to this. In other words, the operation restriction is executed without performing confirmation input, and the display unit 15g or the display device 210 or a separately provided display / alarm means (light, lamp) that the predetermined operation restriction is added before the execution is executed. Etc.), or may not be displayed before execution, but may be displayed while the operation is restricted after execution. Further, the display is not limited to display on the display unit 15g or the display device 210. Instead, other warnings such as a buzzer or other sound warning means may be performed.

  In the first and second embodiments, the determinations in step S130 (or step S130 ′), step S190 (or step S190 ′), and step S260 (step S260 ′) are satisfied, and step S140 (or step S140) is satisfied. ′) And step S150 (step S150 ′), the process proceeds to step S50 (step S150 ′) to select a sewing program under operation restriction. However, the present invention is not limited to this, and the stitch data (sewing conditions) side is selected. You may make it sew using a normal sewing program, performing correction corresponding to some operation restriction, and when generating the drive signal using a normal sewing program and normal sewing data, the drive signal Correction corresponding to some operation restriction at the stage of (amplify the voltage value less than 1.0 times Or a filter instruction signal as a sewing control signal is output to filter means separately provided outside the control device 17 (or the central control device 200) and output as usual from the control device 17 (or the central control device 200). Correction (filtering) corresponding to the above-described operation restriction may be performed on the drive signal. Further, in the second embodiment, the filter instruction signal is output from the central control device 200 to the filter means provided in the control device 17 of the target sewing device M ′ to perform the filtering, or the target sewing device M ′. When the control device 17 performs correction corresponding to the operation restriction on the drive signal generated by using the normal sewing program and normal sewing data as described above, a restriction instruction (such as correction of the drive signal is performed). It is also conceivable to output a correction instruction) signal from the central controller 200. In short, as a result, the actuators whose operation should be changed according to the condition of the detachable parts such as the motors 20, 22, 28, 30 and the air cylinder 34 of the sewing apparatus M or M ′ are finally subjected to predetermined operation restrictions. If it is, it is enough.

  In the first and second embodiments, guidance is displayed on the contents of confirmation to be performed on the operator side as other preparatory work necessary at the time of sewing in step S240 or step S240 ′. Similarly, for example, a newly required part other than the part currently installed on the operator side or a newly required setting may be displayed as guidance.

  Further, in the above, the component type identification information and the individual identification information corresponding to the wireless tag T related to the components 6, 7, 32 (or the component P) are stored, and based on this, the corresponding components mutual and the operation panel 15 are stored. Although the suitability of the combination with the set value of is determined, it is not limited to this. In other words, the setting value by the operation panel 15 is not considered, and only the suitability of the combination between the parts 6, 7, and 32 (or the part P) may be determined. Even in this case, even if parts are replaced, it is possible to easily check the conformity to ensure that the original performance is exhibited and to prevent the occurrence of sewing defects and the deterioration of work efficiency and durability. The original effect of the present invention can be obtained. In that sense, the wireless tag T only needs to store at least only the type identification information of the corresponding parts 6, 7, 32 (or parts P).

  It is also conceivable to manage not only the compatibility of the combination as described above but also the usage history for each of the parts 6, 7, 32 (or parts P). That is, the individual identification information of the corresponding part stored in the wireless tag T is read by the reader / writer 50 or 50 'when attached to (or approaching) the sewing device main body M1 (or the sewing device main body M'1). Depending on the individual, each of the parts 6, 7, 32 (or parts P) has information related to its use (usage history information, operating states of the motors 20, 22, 28, 30 and the air cylinder 24 at the time of use, etc. Amount information) is written and stored in the wireless tag T by the reader / writer 50 or 50 ', or is not written on the wireless tag T side, and is stored in appropriate storage means such as the RAM 17C of the control device 17 (or the RAM 200B of the central control device 200). It may be memorized. For example, in the case of the usage history information, unit usage data may be accumulated and accumulated, or usage time data may be updated every time. In this case, the wireless tag T or RAM 17C (or RAM 200B) constitutes usage information storage means for storing information related to usage.

  In this modification, by storing information related to the use of each component 6, 7, 32 (or component P), the component life of each component 6, 7, 32 (or component P) can be increased for each individual. Since the durability can be prevented by managing individually, it is possible to surely improve the above-described sewing work efficiency.

  At this time, according to the use history information read from the RFID tag T by the tag reader / writer 50 or 50 ', the control device 17 or the central control device 200 performs a predetermined warning display, for example, when the service life is near. Display control signals may be generated and output to the operation panel 15 or the display device 210. As a result, the operator can appropriately recognize that the component life is short according to use, and as a result, the detachable component 6, 7, 32 or the detachable component P is promptly replaced before the durability is lowered. Therefore, it is possible to prevent the sewing work efficiency from being lowered.

  In the above modification, when the use history information is written and stored in the wireless tag T, the wireless tag T related to each component 6, 7, 32, P does not necessarily need to store the individual identification information. That is, in the RFID tag T, only the type identification information of the corresponding parts 6, 7, 32, P and the accumulated value information of the usage time of the parts 6, 7, 32, P, for example, are stored, and the tag reader / writer is stored. It is sufficient if the use time information corresponding to the sewing work time is transmitted and written to the wireless tags T from the 50, 50 'side. In this case, there is no need to transmit information about the usage status or to store the information in the wireless tag T, so that the amount of transmitted or written information can be reduced.

  In the above, the control device 17 (or the central control device 200) refers to the predetermined combination suitability reference table previously stored in the ROM 17B (or ROM 200C) in step S30 (or step S30 ′) The cutter 6, the hammer 7, the cloth presser 32 (or part P) identified from the RFID tag information recognized in step S10 (or step S10 ′), and the “stitch” recognized in step S20 (or step S20 ′). Regarding the set values of “length F”, “stitch pitch”, and “number of stitches in the eyelet portion”, it is determined whether or not the combination is appropriate, but the present invention is not limited to this.

  That is, with respect to one predetermined attachment / detachment component (for example, the cutter 6 or the component P) (or for each of the plurality of attachment / detachment components), the kind to be attached to the sewing apparatus main body M1 (or M'1) or If one individual or a predetermined range is determined, it may be determined only whether the tag reader / writer 50 (or 50 ') can recognize (that is,) the RFID tag information related to the limited part. If it can be recognized, the control device 17 (or the central control device 200) of the sewing device M selects, for example, a normal sewing control program and performs normal sewing control. If it cannot be recognized, the control device 17 17 (or the central control device 200) considers that there is a part that is not a part that is assumed in advance, such as a non-genuine product, or that the part itself is not attached (forgetting to attach a part). Whether a display control signal is generated and output and displayed on the display unit 15g (or display device 210) of the operation panel 15, or a sewing control signal that prohibits the start of the sewing operation is generated and output, or the type of the component Depending on the situation, it is conceivable to generate and output a sewing control signal that enables the sewing operation while restricting the operation in a very limited form. In this case, the tag reader / writer 50 (or 50 ') has a recognition means for recognizing the presence / absence of a detachable component or the presence / absence of a wireless tag handled in association with the detachable component according to claim 1. The control device 17 (or the central control device 200) of the sewing apparatus M configures a first signal generation unit that generates a corresponding sewing control signal or display control signal according to the recognition result of the recognition unit.

  According to this modification, by outputting the signal generated as described above, for example, when the component itself is forgotten to be attached, it is possible to reliably prevent the occurrence of malfunction or failure. In addition, when non-genuine parts are used, as in the above-described embodiment, the sewing is not made impossible and the occurrence of a failure due to a decrease in durability is prevented, so that poor sewing can be prevented in advance and the necessary minimum Sewing performance can be secured, and at least the sewing work efficiency can be improved as compared with a case where sewing is impossible.

  In the above description, the wireless tag T is directly attached (attached) to a target component (the cutter 6, the hammer 7, the cloth presser 32, or the component P in the above example), but is not limited thereto. That is, when attachment is difficult, the wireless tag T may be bundled in a box, container, wrapping paper or the like in which the parts 6, 7, 32, P are packed. , 7, 32, P need only be provided so as to be handled in association with the parts 6, 7, 32, P without losing the association.

  Further, in the above description, the present invention is applied to a so-called eyelet hole sewing machine (for example, Japanese Patent No. 2762696 by the present applicant), but the application target of the present invention is not limited to this. That is, a sewing machine in which the cloth and the cloth are moved in two directions orthogonal to each other (eg, Japanese Patent No. 3354330 by the applicant) ), A so-called tack-stitched sewing machine (for example, a book sewing machine) in which the cloth is pressed against the sewing machine table (bed) side below by a cloth presser as a pressing means, and the cloth presser and the cloth are moved in two directions orthogonal to each other. Applicant's Japanese Patent Laid-Open No. 8-84878, etc.), the cloth is reciprocated only in one predetermined direction by the cloth presser, and the sewing needle is appropriately swung in the direction orthogonal to the predetermined direction.
