Abstract

The present invention relates to a sewing system enabling compatible installation of a counter device and computerization of integrated management of sewing work in a real-time work report platform for linking and collecting thread trimming and needle penetration data. Accordingly, the technical gist of the present invention is to enable an operator to make a real report without an erroneous report or a bubble report when the operator sews according to thread trimming and needle penetration required by a predetermined work standard (a set thread trimming value and a set needle penetration value are calculated in connection with each other, and a defined value signal is transmitted to a touch screen of a control panel so as to be detected and verified), wherein if a defective operation occurs, compared to the thread trimming value and the needle penetration value instructed during a sewing process related to thread trimming and needle penetration (if the operation is differently performed from the set values), a guide is output to the corresponding worker to have the worker re-perform the sewing operation according to the work instruction (if the work is incorrectly performed, a comment is output to modify and correct the work), and the defective sewing situation (the status of erroneous needle penetration or thread trimming) is displayed on a touch screen (21), thereby immediately preventing the defective operation.

Description

A sewing system that integrates the management of sewing work with a real-time work reporting platform that collects and links data on envoys and immersion, and allows for the compatible installation of counter devices.

[0001] The present invention relates to a sewing system capable of integrated management of a real-time work reporting platform that collects thread cutting and immersion data linked to a set work standard, which enables a worker to make a real report without false reports or bubble reports when the thread cutting and immersion work designated by the set work standard is performed by the worker, and computerization of sewing work and compatible installation of a counter device.

[0002] The present invention is characterized in that, when a worker performs a defective operation (an operation that is different from the set value) in comparison with the thread cutting value and thread cutting value instructed during a sewing process regarding thread cutting and thread cutting, a guide is output to the worker to perform the sewing operation again according to the work instructions (a comment is output to correct the operation if the work is done incorrectly), and a defective sewing situation (the status of an incorrect stitch or thread cutting) is displayed on the touch screen of the control panel, thereby immediately notifying the worker of the judgment regarding the incorrect operation.

[0003] In other words, the present invention is characterized by an accurate sewing process that improves productivity and economy while allowing for future prediction.

[0004] In general, a sewing machine is something that can sew fabric, paper, leather, or other fabrics in an automatic or semi-automatic manner. As the industrialization of clothing production progressed, various types of industrial sewing machines were developed and specialized and automated, and there are now over 5,000 types.

[0005] These sewing machines started with the initial hand and foot models and developed into electric sewing machines, electronic sewing machines, and computer sewing machines in that order. In terms of materials, they have diversified from cast iron to aluminum or plastic, and are becoming specialized, automated, and lightweight.

[0006] Meanwhile, the applicant of this application has applied for and received registration of Patent No. 10-1990362 (hereinafter referred to as “prior patent”) at the Korean Intellectual Property Office.

[0007] These prior patents relate to a sewing machine having an autoprocessor function that automatically performs a series of work processes based on pre-set sewing data through a control panel provided on one side of the sewing machine, and a production control system that forms a factory composed of multiple sewing machines into a single sewing unit and manages them in an integrated manner.

[0008] However, although the terms “thread cutting” or “immersion” appear in the detailed description of the invention in the existing prior art patents, the “thread cutting” and “immersion” in the prior art patents are described as being preset as different sewing functions or collected as sewing data (mechanical components such as motors, pulleys, solenoids, etc. and electrical signals are programmed and transmitted to the touch screen of the control panel and server, etc.) and then transmitted or input to the OP (Operation Panel) control panel during work so that the worker can check this and control the production speed.

[0009] That is, the main technical point of the existing prior art patents is to perform balancing to ensure uniform productivity in sewing work, but there is still no countermeasure for workers' false reports (or bubble reports), so problems related to defective sewing continue to occur during actual work.

[0010] In addition, the conventional sewing data module detects the relevant work items (thread cutting, immersion work, etc.) based on the speed of the motor or the counting of the rotation number, and these checking (detection) devices are physical components equipped with mechanical parts and sensors, and are usually installed through a separate control box or control box under or on the side of the sewing machine, and electronic devices such as sensing with the motor and limit switches must be installed in a cumbersome manner. This makes it almost impossible to install during normal sewing work, and installation must be done during non-working hours. Therefore, there are many difficulties in establishing a compatible installation for general sewing machines and a computerized and integrated management line (automation system).

[0011] The present invention is intended to solve the above-described problem, and its technical point is to provide a method for enabling a worker to perform real reporting (set cutting values ​​and immersion values ​​are linked and calculated, and a signal of the defined value is sent to the touch screen of the control panel to detect and verify) without false reporting (or bubble reporting) when a worker performs a specified cutting and immersion operation according to a set work standard.

[0012] The purpose of this invention is to provide a method for promptly recognizing a judgment about an error in a sewing operation by displaying the error sewing situation on a touch screen, by outputting a guide to the worker to re-perform the sewing operation according to the work instructions when a defective operation occurs in comparison with the work-instructed thread cutting value and immersion value during a sewing process regarding thread cutting and immersion.

[0013] In other words, the purpose of the present invention is to provide a precise sewing process that improves productivity and economy while allowing for future prediction.

[0014] In order to achieve this purpose, the present invention comprises a comparison computer (100) in which a real-time cutting value and immersion value actually performed by a worker are linked and calculated, and then compared with the cutting value and immersion value specified by the work standard and reported to the touch screen (21) of the control panel (20) so that the worker can make a real report without an erroneous report or a bubble report; and a counter device (200) in which an RPM sensor (60) is installed on the outer surface of a driving pulley (70) rotated by a motor to detect the rotation speed or rotation number, and a sensing reader (80) is provided on the outside of the driving pulley (70) to sense the rotation speed or rotation number of the driving pulley (70) by a wired or wireless connection while corresponding to the RPM sensor (60).

[0015] Accordingly, the comparison computer unit (100) is configured to output one of the following: when a worker performs a defective operation (when the operation is different from the set value) by comparing the thread cutting value and thread cutting value indicated in the work standard during the sewing process regarding thread cutting and thread cutting, a guide is output to the worker to perform the sewing operation again according to the work instructions (when the operation is done incorrectly, a comment is output to correct it), or a defective sewing situation (status of incorrect stitching or thread cutting) is displayed on the touch screen (21) (so that the worker is immediately notified of the incorrect operation or defect).

[0016] At this time, the counter device (200) is formed so that the RPM sensor (60) is mounted by a rotary fastener (50) when coupled to the drive pulley (70).

[0017] In this way, the present invention has the effect of enabling a worker to perform real reporting (the set cutting value and immersion value are linked and calculated and the defined value signal is sent to the touch screen of the control panel for detection and verification) without false reporting (or bubble reporting) when the specified cutting and immersion work is performed by a worker according to a set work standard.

[0018] The present invention has the effect of enabling the worker to immediately recognize the judgment of the erroneous work by displaying the erroneous sewing situation (the status of the erroneous stitching or thread cutting) on ​​the touch screen, by comparing the erroneous ...

[0019] In other words, the present invention has a predictable effect in the future while improving productivity and economy by performing an accurate sewing process.

[0021] Figure 2 is an example of a sewing machine in which an autoprocessor function according to the present invention is implemented.

[0024] The best embodiment of the present invention is formed by a comparison computer (100) that calculates real-time thread cutting values ​​and immersion values ​​actually performed by a worker and compares them with the thread cutting values ​​and immersion values ​​specified by the work standard, and then reports them to the touch screen (21) of the control panel (20) so that the worker can make a real report without an erroneous report or a bubble report; and a counter device (200) that is installed on the outer surface of a drive pulley (70) rotated by a motor so as to detect the rotation speed or rotation number, and has a sensing reader (80) that senses the rotation speed or rotation number of the drive pulley (70) by a wired or wireless connection while corresponding to the RPM sensor (60) on the outside of the drive pulley (70).

[0025]

[0026] The present invention will be described in more detail below with reference to the attached drawings.

[0027] The comparative computer unit (100) of the present invention described with reference to FIG. 1 is configured to link and collect data on cutting and immersion to enable real-time work reporting, thereby inducing integrated management and accurate sewing work and inducing computerization and platformization.

[0028] First, when the work standard is set through the server (30), a work instruction is sent to the control panel (20).

[0029] For example, in one of the given lines (process lines for each part, such as sewing sleeves, sewing back panels, or sewing side lines), a specific process for each worker (e.g., even in the same line, each worker is divided into several processes, such as the first process, the second process, and so on, and x processes are performed, and in particular, in each process, a setting is given to how many times to cut threads and how many times to sew, at how many cm intervals, and how much total length to sew) is set to the server (30) when a program is set (work standard), and this is set to the control panel (20) as a work instruction.

[0030] Afterwards, by the control of the set control panel, the controller of the sewing machine is linked to the motor (2) and the sewing module, and the motor (2) and the sewing module are physically driven to perform the set function (for example, this part is automatically activated when the setting is given), and the motor (2) and the sewing module (1: a device or device means that causes thread cutting or immersion according to the defined value for thread cutting and immersion, i.e., the number of times set for each individual process: a combination of a needle and a blade, etc.) are formed to perform the specified thread cutting and immersion function.

[0031] At this time, the electronic sewing machine (10: hereinafter referred to as the sewing machine) is configured to perform the sewing function by stepping on the pedal as a device that manually performs the sewing work assigned to the worker when process-specific settings (thread cutting value and stitch count value for each process) are input for the sewing material.

[0032] Accordingly, sewing functions (thread cutting or stitching, etc.) are automatically set as work instructions are linked to the server->control panel (20), and when the corresponding work menu is set, the worker performs the function (called the set work instruction value or defined value <-thread cutting value or stitching value, etc.) through the sewing machine, and performs sewing work for each line and process.

[0033] In other words, when the sewing work standard for each line or process for sewing materials is set by the server (30), the control panel (20) receives this definition value (set value) through the communication module (22), and the daily work schedule, sewing amount, sewing type, etc. are displayed on the touch screen (21).

[0034] The sewing function programs set thereafter are configured to cause the controller (3) of the sewing machine (10) to drive the motor (2), and the controller (3) controls the number of rotations and the rotation speed (linkage between the driving pulley and the driven pulley) of the motor, and cause the sewing module (1) to perform the corresponding sewing work in conjunction with the manual action of the worker (the action of stepping on the pedal) so that semi-automatic (automatic and manual) sewing is performed.

[0035] For reference, the sewing machine (10) is operated manually by the operator stepping on the pedal, and the sewing module (1) automatically performs the sewing function as the type of sewing function is determined according to the work standard instructed by the server (30).

[0036] Another setting that contrasts with this is a method in which the operator sets it through a touchscreen. For example, if the operator presses the menu button on the touchscreen to set 2 thread trims, 150 stitches at 2mm intervals, and a total of 15cm, the sewing module is set to that function, and the operator only needs to step on the pedal to operate the motor and automatically perform that function. In this part, the motor and sewing module are automatically set to the sewing function (program), but the physical operation is performed by the operator stepping on the pedal. As a result, the mechanical sewing function is implemented to be linked in parallel according to the work standard program (the central server aggregates how much of which task was performed over how long).

[0037] For reference, when a work instruction for one of several processes is received from the server on the touch screen (called the operation panel: OP) for a worker on a selected line, the worker performs daily work while checking the workload for the day.

[0038] In addition, the sewing data transmitted from the server is configured to individually or collectively designate sewing work for each side, and to selectively designate sewing functions including sewing speed, stitch count, presser foot up / down, back tack, thread trimming, and wiper between sides.

[0039] Here, the term "side" refers to a one-way section of a sewing material. For example, a square-shaped sewing material is made up of four sides, and a pentagon-shaped sewing material is made up of five sides.

[0040] For example, the control panel (20) is configured to perform sewing work by an auto processing function while determining the sewing speed, number of sewing stitches, etc. based on the distance between the edges forming each edge of the sewing material according to a pre-set work schedule.

[0041] Here, back tack means repeating sewing forward and backward for a short period of time to prevent the thread from unraveling when starting and finishing sewing to join two or more sewing items, and wiper means lifting the upper thread from the sewing item after the knife installed in the sewing machine cuts the sewing thread after sewing is finished.

[0042] Accordingly, terms such as sewing speed, stitch count, presser foot up / down, back tack, thread trimming, and wiper are commonly used when sewing on a general sewing machine, so detailed explanations thereof will be omitted.

[0043] In addition, the touch screen (21) provided on the control panel (20) has five selection menus: MENU, Parameter Setting (PATA SET), Auto Processing (AUTO PROCESS), Pattern (PATTERN), and Home (HOME), and detailed adjustments can be made manually according to each selection menu.

[0044] For example, the menu is for selecting sewing functions, etc., parameter setting is for adjusting parameters for the operation of the sewing machine, op-processing is for checking the setting values ​​for each line and confirming the work progress, pattern is for specifying the pattern to be implemented for each side for sewing, and home is for checking the setting values ​​for sewing work, and details can be added during the program production stage.

[0045] Accordingly, the comparison computer unit (100) is formed as a technical point of the present invention, in which the real-time cutting value and immersion value actually performed by the worker are linked and calculated, and then compared with the cutting value and immersion value specified by the work standard, and then reported to the touch screen of the control panel so that the worker can make a real report without an erroneous report (or bubble report).

[0046] To explain this more specifically, the comparison computer unit (100) is configured to output instructions to the worker to re-perform the sewing work according to the work instructions when a worker performs a defective work (a work that is different from the set value) by comparing the thread cutting value and thread cutting value instructed in the work standard during the sewing process regarding thread cutting and thread cutting (if the work is done incorrectly, a comment is output to correct it) or to display a defective sewing situation (the status of an incorrect thread cutting or thread cutting) on ​​the touch screen (21) (so that the worker is immediately notified or output a notification of an incorrect work or defect).

[0047] For example, when the comparative computer unit (100) issues a thread cutting and immersion work instruction based on the work standard, the worker performs the work. At this time, the worker inputs the thread cutting and immersion values ​​he / she worked on, or if it is divided into multiple processes, only when one process is completed, pressing the end button to complete the process and notify the transition to the next process on the work touch screen (21), thereby forming a real-time work report of the sewing work.

[0048] At this time, when a worker performs a defective operation (operation that is different from the set value) in comparison with the thread cutting and stitching values ​​instructed during the sewing process for thread cutting and stitching, a guide is output to the worker to perform the sewing operation again according to the work instruction (comment content is output to correct the operation if it is done incorrectly), and the defective sewing situation (status of incorrect stitching or thread cutting) is displayed on the touch screen (21), thereby immediately preventing incorrect operations.

[0049] To add a further explanation here, the detection method that recognizes that a cut has occurred is to detect and count a specific speed range when the motor rotates (for example, when the rear pedal is pressed, the mechanical components such as the motor and pulley are converted into an electrical signal together with the solenoid and transmitted to the touch screen of the control panel to indicate the point in time or operation of the cut).

[0050] That is, thread cutting or stitching is performed based on the work standards and work instructions established for each process (work) line, and thread cutting and stitching that occur in the relevant work stage are computerized into sewing data.

[0051] In other words, when work instructions according to work standards are delivered to workers, workers become aware of the work content, and when workers perform sewing work on each process line, the work volume (time / count statistics) is checked and reported to the computer while linking with the control panel (touch screen).

[0052] At this time, the touch screen of the control panel has a definition of the work count for each process (such as the number of cuts or immersion intervals).

[0053] Accordingly, as the power source motor is calculated in proportion to the rotational speed of the drive pulley and driven pulley, a specific signal for a certain function is generated, and a specific sewing (thread cutting or immersion) operation for each process is calculated and applied according to the signal.

[0054] For example, the number of cuts corresponding to the thread cutting (cutting the thread at the finishing stage) is the number of trimmings and is used as the analysis standard during the process. (Check and detect how many times thread cutting is done in one process / For example, if you say to work 20 stitches with a stitch width of 3mm, the process is carried out with an allowance defined.)

[0055] In this way, manual thread cutting and immersion sewing work is improved through network-based sewing control management, and the balancing work is specialized to increase productivity by handling each unbalanced production process in a balanced manner.

[0056] Meanwhile, another technical point of the present invention, the counter device (200), as shown in FIGS. 3 to 7, is a hardware configuration that can be simply and easily installed on all sewing machines available on the market (applicable to all sewing machines). It is characterized by excellent installability and compatibility, enabling rapid construction and setting of an automated line in a short period of time (it can be installed during a break or lunch break during sewing work).

[0057] Accordingly, the counter device (200) is formed so that an RPM sensor (60) for detecting rotation and speed is mounted on the outer surface of a drive pulley (70: a portion between forks or a portion between spaces between forks in a wheel-shaped circumference) that rotates by a motor, and a sensing leader (90) that senses (wired or wirelessly connected) the rotation speed or rotation number of the drive pulley while corresponding to the RPM sensor is provided on the outside of the drive pulley (70).

[0058] That is, the present invention relates to a super-simple installation type compatible device that attaches an RPM sensor (60) for detecting a thread cutting signal to a drive pulley (rotation RPM), which is a main shaft wheel connected to a drive motor, and detects it wirelessly when rotating (when the rotation RPM decelerates at the time of thread cutting or enters a specific deceleration section, the speed is measured and detected) so that it can be used as sewing data.

[0059] For reference, in order to build equipment for the automation and computerization of detection of existing sewing data (thread cutting, stitching, etc.), basic detection equipment (or overall measurement sensing equipment, etc.) must be installed at the bottom of the sewing machine (under the machine).

[0060] At this time, when setting up the detection equipment, additional work such as auxiliary components and parts must be done, which requires work to be stopped during installation, which harms workability (night work if necessary), and causes cost loss (operation stoppage and increase in manufacturing cost, etc.), and in particular, many problems occurred, such as the need to design and reflect specific additional devices for each sewing machine model.

[0061] The present invention is designed to solve this problem, and is configured to determine the thread cutting point by running a test once regardless of the type of sewing machine (checking the speed of the section corresponding to thread cutting), and then define that part as the thread cutting point, and then measure it as a signal.

[0062] That is, it is formed to provide a quick installation process by simply attaching a rotation RPM sensor to the construction wheel, and it is characterized by greatly improving economy and productivity by reducing manufacturing costs, labor costs, and loss costs due to work stoppages, and not causing work delays in the existing production line.

[0063] At this time, the counter device (200) is formed so that the RPM sensor (60) is mounted by a rotary fastener (50) when coupled to the drive pulley (70).

[0064] Accordingly, the rotary joint (50) is largely composed of a holder (51) and a support bracket (52), as shown in FIGS. 3 to 5.

[0065] First, the support bracket (52) is coupled to the wheel spoke (71) of the drive pulley (70), and a flange (52-1) having a bolting hole is formed on the surface corresponding to the wheel spoke side of the drive pulley (70) so as to be bolted in advance.

[0066] At this time, the holder (51) is formed in the form of a clip with one end opened, and a wedge-shaped latch is provided on the open end side so that the outer surface of the RPM sensor can be fixed by biting (compressing by up-and-down elasticity).

[0067] Accordingly, the holder is formed as a separate individual component from the support bracket, and in particular, an insertion ring (55) for fitting is provided on the other end (bulkhead side) of the holder.

[0068] At this time, the outer surface of the insertion ring (55) is formed with a plurality of stoppers (56) and catches (57) at set intervals and steps, and the stopper (56) is formed with an inclined surface (56-1) in the form of an uphill slope along one rotation direction, so that when inserted into the insertion hole (53) of the support bracket, it is formed to be closely fixed with the hemispherical surface of the hemispherical protrusion (54) formed on the inner surface of the insertion hole.

[0069] At this time, an arc-shaped or hemispherical mounting groove (56-2) is formed on the high-top height side of the section of the slope (56-1) so that the hemispherical surface of the hemispherical protrusion (54) corresponds to it and prevents over-rotation in the circumferential direction while being formed to be combined in a one-touch fitting manner. (Pressure fastening after storage at the highest height)

[0070] Accordingly, the catch (57) is formed to have a cross-section in the shape of a D-shape with one side open by being positioned in a direction perpendicular to the stopper (approximately 90°) or at an angle spaced apart from the stopper by a set angle.

[0071] The long side of this catch (the long side connecting the short leg of the D-shaped insert) is formed to prevent the insertion ring inserted into the insertion hole from falling out by entering the bottom (or side) of the hemispherical projection along with the rotation of the insertion ring.

[0072] In other words, the rotary joint (50) of the present invention is composed of a holder (51) and a support bracket (52), and is formed so that the insertion ring of the holder corresponds to the insertion hole of the support bracket and is assembled into the insertion hole.

[0073] At this time, the insertion ring is formed with a stopper and a catch on the outer surface to correspond to the hemispherical projection of the insertion hole and, when rotating, is formed so that the hemispherical surface of the hemispherical projection is pressed and fixed in a male-female protrusion shape through the inclined surface of the stopper and the mounting groove.

[0074] Accordingly, the catch is formed to catch on one end (inner end) of the hemispherical projection so that the holder does not come off when assembled with the support bracket. (Conversely, it is formed to be released when rotated in reverse.)

[0075] This is to ensure quick joining and fastening, easy workability, and high fastening reliability.

[0076] For reference, the RPM sensor is positioned proportionally to the number of spokes or at regular intervals, and measures the rotational speed of the drive pulley or the rotational speed of the RPM sensor while approaching the sensing leader, and wirelessly reads information about thread cutting or immersion, so that the sewing function can be performed according to the relevant work standard in the same form as before (wired control program).

[0077] The present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary skill in the art to which the present invention pertains can make various modifications without departing from the gist of the present invention claimed in the claims, and such modifications are within the scope of the claims.

[0078] The present invention enables a worker to make a real report without an erroneous report or bubble report when a thread cutting and immersion work designated by a set work standard is performed by the worker. In particular, the present invention enables a worker to make a real report without an erroneous report or bubble report when a defective work (a work that is different from the set value) occurs in a sewing process related to thread cutting and immersion by comparing the thread cutting value and immersion value instructed during the work process, and outputs a guide to the worker to perform the sewing work again according to the work instruction (in case of an incorrect work, a comment is output to correct it), and a defective sewing situation (the status of an incorrect thread cutting or immersion) is displayed on the touch screen of the control panel, thereby enabling an immediate recognition of a judgment on an erroneous work, which is industrially applicable.
