Detailed Description

[ outline of embodiments of the invention ]

Next, a sewing device according to the present invention will be described with reference to the drawings. Fig. 1 is a front view of a sewing machine 10 as a sewing apparatus, fig. 2 is a left side view, and fig. 3 is a functional block diagram showing a control system.

The sewing machine 10 includes: a needle vertical moving mechanism which uses the sewing machine motor 11 as a driving source and provides vertical moving action to the needle bar holding the sewing needle 2; a lower feeding mechanism which utilizes the power of the sewing machine motor 11 to convey the sewed object from the lower part of the needle plate through the feeding teeth; an upper feeding mechanism which conveys the sewed object from the upper feeding part 4 contacted with the upper part of the sewed object by the power of the sewing machine motor 11; a kettle mechanism; a cloth presser foot 3 for pressing the sewed object on the needle plate from the upper part; a needle swing mechanism which makes the needle bar move arbitrarily in the direction orthogonal to the cloth feeding direction; a thread regulator device which gives thread tension to the upper thread passing through the sewing needle 2; a thread take-up lever for lifting the upper thread; a thread cutting device for cutting the sewing end of the upper thread and the lower thread; a display input device 80 as a display input unit for displaying various information related to sewing and receiving input of various settings; a control device 90 for controlling the operation of each component of the sewing machine 10; and a sewing machine frame 20 which accommodates or supports each structure of the sewing machine 10.

In the following description, a horizontal direction parallel to a direction in which the lower feed mechanism conveys the workpiece is referred to as an X-axis direction, a downstream side of the workpiece in the feed direction is referred to as "front", and an upstream side of the workpiece in the feed direction is referred to as "rear". The direction horizontal and orthogonal to the X-axis direction is the Y-axis direction, the left-hand side facing forward is the "left", and the right-hand side is the "right". In addition, a direction orthogonal to the X-axis direction and the Y-axis direction is a Z-axis direction, one of which is "up" and the other is "down".

The sewing machine frame 20 has: a sewing machine base part 21 extending along the Y-axis direction; a vertical body part 22 rising from a right end part of the sewing machine base part 21; and a sewing machine arm 23 projecting leftward in the Y-axis direction from an upper end of the longitudinal body portion 22.

A needle bar for holding the sewing needle 2, the cloth presser foot 3 and the upper feed portion 4 are supported at the lower part of the left end of the arm portion 23 of the sewing machine.

A rectangular display screen of the display input device 80 is disposed on the front surface side of the vertical body section 22. The front surface of the vertical body section 22 and the display screen of the display input device 80 that is flush with the front surface are constituted by inclined surfaces that slightly incline rearward on the upper side and the left side of the X-Z plane.

The display screen of the display input device 80 is inclined as described above, so that the operator of the sewing machine who performs work by facing the needle drop position with respect to the sewing machine 10 from the rear can easily observe the display screen.

The upper surface of the sewing machine base part 21 is a smooth surface along the X-Y plane, and a needle plate not shown is disposed at the needle drop position of the sewing needle 2 in a plane with the upper surface of the sewing machine base part 21.

Since the needle vertical movement mechanism is the same as a known mechanism, a detailed description thereof will be omitted. The needle up-down moving mechanism uses a sewing machine motor 11 built in the sewing machine as a driving source, and can move the needle bar up and down through a crank mechanism.

Since the needle swing mechanism is the same as a known mechanism, a detailed description thereof is omitted. The needle swing mechanism includes: a support frame which supports the needle bar in a manner of moving up and down; and a needle swing motor 15 for arbitrarily moving the tip end of the needle bar in the Y-axis direction via the support frame.

The tank mechanism is the same as a known mechanism, and therefore, a detailed description thereof is omitted. The pot mechanism has a pot which is rotated by power from a sewing machine motor 11 at the lower side of a needle plate, catches a loop of an upper thread from a descending sewing needle 2 and winds the upper thread with the lower thread, and forms a stitch on a sewing object.

The take-up lever is moved up and down by power from a sewing machine motor 11 in a cycle identical to the needle drop. The upper thread towards the sewing needle is arranged on the thread take-up lever frame, and the upper thread is lifted by the kettle when the stitches of the upper thread and the lower thread are formed so as to fasten the stitches.

Since the lower feed mechanism is the same as a known mechanism, a detailed description thereof is omitted. The lower feed mechanism has feed teeth for advancing and retracting the tooth tips from the opening of the needle plate, and the reciprocating motion in the X-axis direction and the reciprocating motion in the Z-axis direction are taken out from the sewing machine motor 11 and applied to the feed teeth. Thereby, the feed teeth perform an oblong motion around the Y axis in the X axis direction in the longitudinal direction. When the feed teeth pass through the upper part of the orbit of the oblong motion, the tooth tops move forward while protruding upward from the opening part of the needle plate, and the sewing object on the needle plate is conveyed forward.

The lower feed mechanism further includes a lower feed adjustment motor 12, and the lower feed adjustment motor 12 adjusts the stroke width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, and can arbitrarily adjust the feed amount of the workpiece by the feed teeth.

The upper feed mechanism is the same as a known mechanism, and therefore, a detailed description thereof is omitted. The upper feed mechanism has an upper feed portion which is brought into contact with the workpiece at the needle drop position from above the needle plate to perform a feed operation, and takes out the reciprocating operation in the X-axis direction and the reciprocating operation in the Z-axis direction from the sewing machine motor 11 to be applied to the upper feed portion. Thereby, the upper feed portion performs an oblong motion around the Y axis in the X axis direction in the longitudinal direction. When the upper feed portion passes through the lower portion of the orbit of the oblong motion, the front end portion moves forward along the upper surface of the needle plate, and the sewn object on the needle plate is conveyed forward.

The upper feed mechanism further includes an upper feed adjustment motor 13, and the upper feed adjustment motor 13 adjusts the stroke width of the reciprocating motion in the X-axis direction transmitted from the sewing machine motor 11, and can arbitrarily adjust the feed amount of the workpiece by the feed teeth.

The upper feed unit can be manually switched between a retracted position where feeding is not performed and a feed position where feeding is performed, and can be selected whether or not upper feeding is performed. A sensor for detecting which position the upper feeding portion is at, the retracted position or the feeding position may be provided, and a detection signal thereof may be input to the control device 90.

The cloth presser foot 3 is provided above the needle fall position of the needle plate and can press the sewed object from above. The cloth presser foot 3 is attached to the lower end portion of a presser foot bar supported to hang down from the lower portion of the left end of the sewing machine arm 23. The presser bar is provided with spring pressure in the sewing machine arm 23, and the cloth presser 3 is pressed toward the needle plate side to provide presser pressure to the object to be sewn.

The cloth presser foot 3 has a plurality of types, and can be replaced with an appropriate cloth presser foot 3 according to the type of sewing.

The presser bar can retract the cloth presser 3 upward by a manual lever or a presser motor 14, not shown. The presser foot motor 14 can arbitrarily adjust the presser foot pressure of the cloth presser foot.

Since the wire adjuster device is the same as a known mechanism, a detailed description thereof is omitted. The thread adjusting device is not shown in the drawings, but holds the upper thread in the middle of the path of the upper thread and applies tension to the upper thread by the holding pressure. The thread adjuster device can adjust the clamping pressure by the thread adjuster solenoid 16, thereby giving an arbitrary thread tension to the upper thread.

Since the thread cutting device is the same as a known mechanism, a detailed description thereof is omitted. The thread cutting device is provided with a cutter working between the needle plate and the kettle mechanism, and is used for cutting off the upper thread and the lower thread. The thread cutting device has a thread cutting solenoid 17 for operating the cutter.

The display input device 80 includes: a display part 81 provided on the front surface side of the longitudinal body part 22 of the sewing machine frame 20; a touch panel 82 provided so as to overlap the front surface side of the display section 81; and three rotating disks 83, 84, 85 arranged substantially in the Y-axis direction immediately below the display portion 81. The portion of the display input device 80 including the display section 81 and the touch panel 82 corresponds to a touch operation type display input device in the present embodiment, and the reels 83, 84, and 85 are hardware reels corresponding to hardware operation sections.

The display unit 81 is composed of a liquid crystal display and an organic el (electro luminescence), and displays an input screen G1 described later by display control performed by the control device 90. The touch panel 82 functions as an input detection unit that detects a contact input position of an operator of the sewing machine and detects an input operation on the input screen G1.

The three rotation disks 83, 84, and 85 each include an encoder 831, 841, and 851, and the rotation operation amount of the operator is input to the control device 90 via the encoders 831, 841, and 851.

The control device 90 can read the sewing pattern data, control the lower feed adjusting motor 12 and the needle swing motor 15, and perform sewing for forming stitches corresponding to the sewing pattern.

[ display control of display input device ]

The display control of the display input device 80 by the control device 90 will be described. The display control and input processing performed by the display input device 80 described below are all performed by the CPU 91 of the control device 90 executing a program in the ROM 92.

Fig. 4 is an explanatory view showing an example of display of the input screen G1 displayed on the display unit 81 of the display input device 80, and fig. 5 is an explanatory view showing division of a plurality of display areas of the input screen G1 by imaginary lines. In the explanatory drawings showing these display examples and the explanatory drawings showing other display examples described later, the upper, lower, left, and right sides of the paper surface substantially coincide with the upper, lower, left, and right sides of the sewing machine 10.

As shown in the drawing, the input screen G1 is rectangular in overall length and is divided into a first region R1 extending over the entire left-right width of the upper end of the screen, a second region R2 extending over the entire left-right width of the lower portion of the screen, third to fifth regions R3 to R5 disposed below the first region, and a sixth region R6 extending over the entire left-right width of the lower end of the screen.

The third to fifth regions R3 to R5 are vertically long rectangular regions each obtained by dividing the region between the second region R2 and the sixth region R6 into three parts in the left-right direction, and the left side is the third region R3, the center is the fourth region R4, and the right side is the fifth region R5.

The third to fifth regions R3 to R5 are trisected in the left-right direction in the example of fig. 5, but are not limited thereto, and the ratios may be increased or decreased. For example, the left and right widths of the central fourth region R4 may be changed to be 1/4 to 1/2 of the entire width, and the left and right widths of the third region R3 and the fifth region R5 may be made equal on both sides.

In the first region R1, a support button B11, a setting button B12, a sewing button B13, a history button B14, and a portal button B15 for switching to various input screens are arranged in order from left to right.

These buttons B11 to B15 can be operated by touching the button positions to perform button input. Further, by sliding the first region R1 to the left and right, the positions of the buttons B11 to B15 can be scrolled.

The support button B11 is a button for switching the display to a support screen on which an operation manual or the like of the sewing machine 10 is displayed.

The setting button B12 is a button for switching the display to a setting screen for setting the brightness of a not-shown work light, the sound volume of a not-shown speaker, and the like with respect to the surrounding environment of the sewing machine 10.

The sewing button B13 is a button for switching the display to the input screen G1 of fig. 4. The input screen G1 enables various settings related to sewing.

The history button B14 is a button for switching the display to a history screen not shown. The history screen is an input screen for calling a plurality of sewing patterns which have been sewn in the past and for calling the sewing pattern data and the record data related to the setting of the sewing pattern data at the time of sewing.

The portal button B15 is a button for switching display to a browser screen for connection to the web portal of the sewing machine 10 via a network line.

In the second region R2, a cloth presser foot candidate display frame W21 configured by graphic and character string display for switching to various display screens, a selection button B21 of a sewing pattern as an operation portion, a setting button B22 of the sewing pattern, and a circulation selection button B23 are arranged in order from the left.

In the cloth presser candidate display frame W21, the type of the cloth presser 3 suitable for the sewing pattern currently selected is displayed. For example, in the example of fig. 4, graphic information and character information suitable for the selected sewing pattern are displayed for the cloth presser a and the cloth presser B.

The selection button B21 for the sewing pattern has a substantially rectangular contact range, and if the contact range is touched, the display is switched to the selection screen G3 for the sewing pattern (fig. 6). A plurality of types of sewing patterns are registered in the control device 90, and a pattern number (identification number) is set in each sewing pattern. When the pattern number is selected on the selection screen G3, the selected pattern number (identification number) is displayed within the substantially rectangular contact range of the selection button B21.

The selection of the sewing pattern is described in detail below.

Fig. 6 is an explanatory diagram showing an example of display of a sewing pattern selection screen G3 displayed on the display unit 81 of the display input device 80.

Type names B71-B73 are displayed in the upper part of the selection screen G3. A pattern number (identification number) is displayed in a lower portion of the selection screen G3. The pattern number is composed of 3 digits of hundred digits a41, ten digits a42, and ones digits a 43.

Further, a line a44 indicating that the dial 83 corresponds to the operation of the hundred a41, a line a45 indicating that the dial 84 corresponds to the operation of the ten a42, and a line a46 indicating that the dial 85 corresponds to the operation of the unit a43 are displayed below the pattern numbers a 41-a 43 in the selection screen G3.

In addition, a list page L3 of a sewing pattern is displayed in the area between the genre name B71-B73 and the pattern number A41-A43 in the selection screen G3.

In fig. 6, the first 15 thumbnail stitching patterns B101-of the list page L3 of buttonhole hem B72 are shown in a 5 x 3 horizontal matrix.

The thumbnails will be described as B001 to B999 in the order of the pattern numbers 001 to 999. There are some cases where a pattern number (missing number) to which no sewing pattern is assigned.

In fig. 6, sewing pattern thumbnails B101 to B105 are arranged in the upper stage, sewing pattern thumbnails B106 to B110 are arranged in the middle stage, and sewing pattern thumbnails B111 to B115 are arranged in the lower stage. The lower part of the lower sewing pattern thumbnails B111-B115 superimposed as the background of the pattern numbers a 41-a 43 is a gradation display gradually becoming darker as the lower part is directed downward, and the contrast with the pattern numbers a 41-a 43 is improved, so that the pattern numbers a 41-a 43 can be easily read.

Further more than 15 sewing patterns are registered in the list page L3 of the buttonholing B72, and by flicking (or sliding) the selection screen G3 in the vertical direction, the subsequent sewing pattern thumbnail of the sewing pattern thumbnail B115 can be displayed, or an operation of returning to the upper part of the page can be performed, whereby the entire list page L3 can be viewed.

Further, by flicking the selection screen G3 in the horizontal direction, it is possible to display other types of list pages (for example, the list page of the stitch B73 by flicking from the left in fig. 6).

As described above, all sewing patterns can be read.

In each sewing pattern thumbnail B101-, in addition to the pattern of the sewing pattern, the pattern number of the sewing pattern is displayed. The graphics of the entire sewing pattern and the list of the pattern numbers are also provided by other media as shown in fig. 7, for example. Fig. 7 shows a configuration example in which a sewing pattern list 89 is arranged inside an upper cover 88 of the sewing machine arm 23. The inner end of the upper cover 88 is supported by a hinge, and fig. 7 shows a state where the upper cover 88 is opened.

Each sewing pattern thumbnail B101-becomes a software key, and can be selected and determined by touching it with a finger or the like.

The selection method of the pattern number can be performed as follows.

The hundreds a41 of the pattern number is a number for identifying each type and each list page. For example, in fig. 6, the hundred a41 is "1", and a list page L3 of the buttonhole serging B72 is specified, and this list page L3 is displayed on the selection screen G3.

When the dial 83 is rotated to change the hundreds a41, a list page corresponding to the number of the hundreds a41 is displayed on the selection screen G3.

The hundreds position a41, the tens position a42, and the units position a43 form an identification number for identifying each sewing pattern.

Currently, if the dial 83 is rotated to set the hundreds position a41 to "1", the dial 84 is rotated to set the tens position a42 to "0", and the dial 85 is rotated to set the units position a43 to "6", that is, if the identification number (a 41-a 43) is set to "106", the sewing pattern thumbnail B106 is displayed as shown in fig. 6.

As described above, the control device 90 controls switching of the sewing pattern displayed on the display portion 81 in accordance with the input operation to the hardware operation portion (83, 84, 85).

In response to an input operation to the hardware operation unit (83, 84, 85), the control device 90 displays the identification number (a 41-a 43) of the sewing pattern on the display unit 81, and also displays the sewing pattern (B106) specified by the identification number.

In the present embodiment, the control device 90 displays the identification number (a 41-a 43) of the sewing pattern on the display 81 in response to the input operation to the hardware operation unit (83, 84, 85), and also displays a list page (L3) including the sewing pattern (B106) identified by the identification number and other sewing patterns.

The list page L3 of the buttonholing B72 has sewing patterns from the identification numbers "101" to "122" registered therein.

For example, if the dials 83 to 85 are rotated and the identification number (A41-A43) is set to "112", the sewing pattern thumbnails B111 to B115 including the sewing pattern thumbnail B112 are displayed in the middle stage.

For example, if the dials 83 to 85 are rotated and the identification number (a 41-a 43) is set to "118", the sewing pattern thumbnails B116 to B120 (not shown) including the sewing pattern thumbnail B118 (not shown) are displayed in the middle stage.

The control device 90 controls the above display.

The control device 90 displays the portion of the list page (L3) including the sewing pattern (B106) specified by the identification number (a 41-a 43) in an enlarged manner, and controls the portion to be capable of displaying the other portion of the list page by scrolling. When the identification number is input through the hardware operation unit (83, 84, 85), the control device 90 arranges the sewing pattern specified by the identification number in a predetermined area on the screen. In the present embodiment, the control device 90 sets the predetermined region as a vertical central region (middle region) of the screen G3. The predetermined region may be a central region in the horizontal direction of the screen (in the case of horizontal scrolling) or may be a central region in the vertical and horizontal directions of the screen (in the case of vertical and horizontal scrolling) depending on the scrolling direction of the list page.

The identification numbers of the sewing patterns included in the uppermost stages (B101 to B105) and the last stages (B121 to 122) of the list pages are aligned by the dials 83 to 85, but are not limited thereto. The uppermost stages (B101-B105) are displayed in the upper stage, and the final stages (B121-122) are displayed in the lower stage. The vacant part is set to a non-rolling display mode, and the aim is to display as many sewing patterns on the screen as possible. The sewing patterns included in the uppermost stages (B101 to B105) and the final stages (B121 to 122) of the list page may be displayed in the middle stage after being aligned by the dials 83 to 85.

If the user touches the stitched pattern thumbnail B106 with a finger or the like, the stitched pattern applied to stitching is determined as the stitched pattern thumbnail 106. That is, the control device 90 determines the sewing pattern based on the screen touch on one sewing pattern (B106) in the list page (L3) detected by the input detection section (touch panel 82). After the sewing pattern is determined, the control device 90 returns to the input screen G1 to display the pattern number of the sewing pattern determined as the selection button B21.

Further, in the case where the missing number is aligned by the dials 83 to 85, the control device 90 does not perform the change control of the display portion of the list page displayed on the selection screen G3.

The setting button B22 of the sewing pattern has a circular contact range, and an icon indicating the setting button is displayed on the inner side. If the setting button B22 is touched within the contact range, the display is switched to a predetermined setting screen. From this setting screen, settings relating to sewing patterns other than the parameters set by the buttons B31 to B53 described later can be made. For example, pattern editing such as vertical inversion and horizontal inversion of the sewing pattern can be performed from the setting screen.

The cycle selection button B23 has a circular contact range set therein, and an icon indicating that the button is a cycle selection button is displayed inside the button. If the touch cycle selection button B23 is within the contact range, it can be set whether to perform single-shot sewing or continuous sewing, wherein the single-shot sewing is performed in a single sewing pattern, and the continuous sewing is repeated. When the single-shot sewing is set for the loop selection button B23, the number of "1" is displayed inside the icon, and when the repeated sewing is being selected, display control is performed to delete the number inside the icon.

Three buttons serving as operation sections for setting a predetermined sewing pattern are arranged vertically in the third region R3 and the fifth region R5, respectively.

In the third region R3, a sewing start process setting button B31, a thread tension setting button B32, and a sewing end process setting button B33 are arranged in this order from above.

In the fifth region R5, the upper feed setting button B51, the presser foot raising setting button B52, and the tangent line setting button B53 are arranged in this order from above.

The various setting buttons B31, B32, B33, B51, B52, and B53 have circular contact ranges, and icons serving as content display units that display contents input from the setting buttons are displayed on the inner sides of the contact ranges.

In addition, setting information display units W31, W32, W33, W51, W52, and W53 as content display units are disposed on the outer lower portions of the various setting buttons B31, B32, B33, B51, B52, and B53, respectively, and display the contents input from the setting buttons and the setting values or setting states thereof by character information.

The sewing start processing setting button B31 is a button for selecting whether or not to execute sewing stop at the sewing start end and the type of sewing stop. For example, by repeatedly touching the contact range of the sewing start processing setting button B31, the settings of return sewing, sewing stop of the band, and sewing non-stop can be switched.

The wire tension setting button B32 is a button for arbitrarily setting the wire tension of the wire adjuster device generated by the wire adjuster solenoid 16.

[ conclusion, Effect and others ]

As described above, the control device 90 controls switching of the sewing pattern displayed on the display portion 81 in accordance with the input operation to the hardware operation portion (83, 84, 85).

Therefore, when the number of pages is far from the currently displayed page to the page desired to be displayed, the rotation operation of the dial avoids the trouble of performing touch operation such as flicking for a plurality of times on the screen, and the operability of selecting the sewing pattern improves. The operation performed by the hardware dial requires a smaller operation workload and a smaller behavior than the screen touch operation performed by a screen moving operation such as flicking or sliding, and thus the operation time is shortened.

The present invention is not limited to the above embodiment, and the effects can be obtained by implementing only the hardware operation unit (83) corresponding to the page turning operation. Therefore, the pattern number may not be necessarily specified.

As described above, the control device 90 displays the identification number (a 41-a 43) of the sewing pattern on the display 81 in response to the input operation to the hardware operation unit (83, 84, 85), and also displays the sewing pattern (B106) specified by the identification number.

Therefore, if the user knows the identification number of the sewing pattern, the user can input the identification number and directly call the desired sewing pattern on the screen, and the operability of selecting the sewing pattern is improved.

As described above, the control device 90 displays the identification number (a 41-a 43) of the sewing pattern on the display 81 in response to the input operation to the hardware operation unit (83, 84, 85), and also displays the list page (L3) including the sewing pattern (B106) identified by the identification number and other sewing patterns.

The sewing patterns are sorted by a plurality of list pages, and the sewing patterns similar to each other are arranged relatively close to each other in each list page.

Therefore, the user can easily select a sewing pattern similar to the sewing pattern with the known identification number by a small number of operation steps, and the operability of selecting the sewing pattern is improved.

As described above, the controller 90 controls the display of the other part of the list page (L3) including the sewing pattern (B106) identified by the identification number (a 41-a 43) by enlarging the display of the other part and scrolling the list page.

Therefore, even if the number of sewing patterns of the same type is large, the sewing patterns can be displayed in an enlarged manner and easily viewed by enlarging a part of the list page, and the sewing patterns can be easily viewed to the corner of the page by scrolling, thereby improving the operability of selecting the sewing patterns.

As described above, the control device 90 arranges the sewing pattern specified by the input identification number in a predetermined region (in the above-described embodiment, in the middle stage).

Therefore, the user can easily find the sewing pattern corresponding to the identification number of the input operation on the screen, and the operability of selecting the sewing pattern is improved.

By setting the predetermined region as the central region in the vertical direction or/and the horizontal direction of the screen, the sewing pattern corresponding to the identification number input by the user can be displayed easily in the screen, and the sewing patterns similar in the front and rear can be displayed, so that the operability of selecting the sewing pattern is improved.

As described above, the scrolling of the screen and the determination of the sewing pattern can be performed by the screen touch, and the operability of the cooperation between the hardware operating units (83, 84, 85) and the touch panel 82 is improved, and the operability of the selection of the sewing pattern is improved.

As described above, the dials 83, 84, 85 capable of changing the numerical value of the bit of the identification number are provided as hardware operation units independently for each bit of the identification number.

Therefore, the dial having no changed position does not need to be operated, and only 10 steps of 0 to 9 operations are required for 1 dial, and the like, so that the amount of operation of the dial is reduced, and the operability of selecting a sewing pattern is improved.

Further, since the dial is applied as the hardware operation unit, operability is also good and operability of selecting a sewing pattern is improved as compared with an operation by 2 keys (an increasing key and a decreasing key) for increasing or decreasing the number.

In the above embodiment, the hardware operation unit does not hinder the selection of the components other than the dial. For example, a hardware numeric keypad may be used to input a pattern number.
