When it has the bent portion, it may be difficult to pass through, such as being caught by the bent portion when a string-like member such as a belt is passed inside the loop.

本発明の目的は従来に比べループ内にベルト等の紐状部材を通しやすいループ片を縫製装置に供給できるループ片供給装置を提供することである。   An object of the present invention is to provide a loop piece supply device that can supply a loop piece that can easily pass a string-like member such as a belt through the loop to a sewing device as compared with the prior art.

本発明の一態様に係るループ片供給装置は、ループ片を縫製装置に供給するループ片供給装置において、ループ片の長さ方向中央部を載置する載置面を有し、前記載置面は前記ループ片の前記長さ方向の両端部と接触しない載置部と、前記載置部から上方に離間した位置に設け、前記載置部側に移動して、前記載置部に載置した前記ループ片を押さえる押圧部と、前記ループ片の幅方向に延びる棒状の第一部材と第二部材を各々有し、前記ループ片の前記両端部の各々に対応する位置に移動して前記押圧部が押さえた前記ループ片の前記両端部の各々を挟持する一対の挟持部と、前記一対の挟持部の各々が前記両端部を挟持した時、前記一対の挟持部の前記長さ方向の間隔を縮める間隔変更手段と、前記一対の挟持部の各々において、上下一対の前記第一部材、前記第二部材のうち上側の前記第一部材を下側の前記第二部材に向けて移動する挟持部第一駆動手段と、前記押圧部が前記ループ片を押さえた時、前記挟持部第一駆動手段により前記ループ片の前記両端部を前記第一部材と前記第二部材で上下方向から挟持する挟持部第一制御手段とを備え、前記載置部の前記載置面に垂直な方向において、前記載置面の位置と前記挟持部第一制御手段により前記一対の挟持部が挟持する前記両端部の位置は異なる。 The loop piece supply device according to one aspect of the present invention is a loop piece supply device that supplies a loop piece to a sewing device, and has a placement surface on which a central portion in the length direction of the loop piece is placed. Is provided at a position where the loop piece does not come into contact with both ends in the length direction and a position spaced upward from the placement section, and moves to the placement section side and is placed on the placement section. Each having a pressing portion for holding the loop piece, a rod-shaped first member and a second member extending in the width direction of the loop piece, and moving to positions corresponding to the both ends of the loop piece, A pair of clamping parts that clamp each of the both ends of the loop piece pressed by the pressing part, and when each of the pair of clamping parts clamps the both ends, the length direction of the pair of clamping parts and distance changing means for reducing the gap in each of said pair of holding portions, upper and lower one When the first pressing member presses the loop piece, the first driving means for moving the first member on the upper side of the first member and the second member on the second member toward the second member on the lower side. The holding part first control means for holding the both end parts of the loop piece by the first member and the second member from above and below by the holding part first driving means, In the direction perpendicular to the surface, the position of the mounting surface is different from the positions of the both end portions sandwiched by the pair of sandwiching portions by the sandwiching portion first control means.

本態様のループ片供給装置では押圧部が載置部から離間した時、一対の挟持部の長さ方向の間隔を縮める。一対の挟持部の長さ方向の間隔を縮める時、ループ片は長さ方向において撓む。ループ片供給装置は長さ方向に撓むループ片を縫製装置に供給する。縫製装置が長さ方向に撓んだループ片の両端部を縫製した時、ループ片にベルト等の紐状部材を通すための隙間ができる。故に縫製装置が長さ方向に撓んだループ片の両端部を縫製した時、縫製装置が長さ方向に撓んでいないループ片の両端部を縫製した時に比べ、ループ片はベルト等の紐状部材を通しやすい。即ちループ片供給装置は従来に比べベルト等の紐状部材を通しやすいループ片を縫製装置に供給できる。載置部の載置面に垂直な方向において、載置部の載置面の位置と一対の挟持部が挟持するループ片の両端部の位置が異なる時、ループ片は両者の位置関係に応じた側に凸を形成して撓む。ループ片供給装置は載置部の載置面と垂直な方向における載置部の載置面の位置と一対の挟持部が挟持するループ片の両端部の位置を調整することによりループ片が撓む方向を制御できるIn the loop piece supply device of this aspect, when the pressing portion is separated from the placement portion, the interval in the length direction of the pair of sandwiching portions is reduced. When the lengthwise interval between the pair of sandwiching portions is shortened, the loop piece bends in the lengthwise direction. The loop piece supply device supplies a loop piece that is bent in the length direction to the sewing device. When the sewing device sews both end portions of the loop piece bent in the length direction, a gap is formed for passing a string-like member such as a belt through the loop piece. Therefore, when the sewing device sews both ends of the loop piece that has been bent in the length direction, the loop piece has a string-like shape such as a belt compared to when both ends of the loop piece that has not been bent in the length direction have been sewn Easy to pass the member. That is, the loop piece supply device can supply a loop piece that is easier to pass a string-like member such as a belt to the sewing device than the conventional one. When the position of the mounting surface of the mounting unit and the position of both ends of the loop piece clamped by the pair of clamping units are different in the direction perpendicular to the mounting surface of the mounting unit, the loop piece depends on the positional relationship between the two. Forms a convex on the other side and bends.

The loop piece supply device cuts the continuous strip member when the pressing portion presses the continuous strip member. Therefore, the loop piece supply device can suppress the cut surface from being distorted with respect to the width direction of the continuous strip-shaped member. The loop piece supply device can suppress the deterioration of the finished quality of the loop piece.

本態様のループ片供給装置において、前記垂直な方向において、前記載置面の位置は前記一対の挟持部が挟持する前記両端部の位置よりも上側にあってもよい。ループ片供給装置では載置部の載置面に垂直な方向において、載置面の位置が一対の挟持部が挟持するループ片の両端部の位置よりも押圧部側にある時、ループ片は載置面から上側に凸を形成して撓む。ループ片供給装置はループ片が撓む方向を載置面に対し押圧部側にできる。   In the loop piece supply device of this aspect, in the vertical direction, the position of the placement surface may be above the positions of the both end portions sandwiched by the pair of sandwiching portions. In the loop piece supply device, when the position of the placement surface is closer to the pressing portion than the positions of both ends of the loop piece sandwiched by the pair of sandwiching portions in the direction perpendicular to the placement surface of the placement portion, the loop piece is A convex is formed on the upper side from the mounting surface to bend. The loop piece supply device can set the direction in which the loop piece bends to the pressing portion side with respect to the placement surface.

本態様のループ片供給装置において、前記一対の挟持部を前記ループ片の前記幅方向に移動する挟持部第二駆動手段と、前記挟持部第一制御手段が前記挟持部第一駆動手段により前記ループ片の前記両端部を前記第一部材と前記第二部材で上下方向から挟持した時、前記押圧部を前記載置部から離間する押圧部制御手段と、前記押圧部制御手段が前記押圧部を前記載置部から離間した時、前記挟持部第二駆動手段により前記一対の挟持部を前記ループ片の前記幅方向に移動して前記載置部から前記ループ片を離間する挟持部第二制御手段と、前記挟持部第二制御手段が前記挟持部第二駆動手段により前記載置部から前記ループ片を離間した時、前記挟持部第二駆動手段により前記一対の挟持部を前記ループ片の前記幅方向に移動して前記ループ片を前記縫製装置に供給する挟持部第三制御手段とを更に備え、前記間隔変更手段は、前記挟持部第三制御手段が前記ループ片を前記縫製装置に供給する時、前記一対の挟持部の前記長さ方向の間隔を縮めてもよい。ループ片供給装置は押圧部が載置部から離間した時、一対の挟持部のループ片の長さ方向の間隔を縮める。この時、凸を形成したループ片は長さ方向において撓む。ループ片供給装置のループ片供給装置は押圧部が載置部から離間していない状態で一対の挟持部のループ片の長さ方向の間隔を縮める時に比べ長さ方向に撓むループ片をより確実に縫製装置に供給できる。   In the loop piece supply device according to this aspect, the sandwiching portion second drive means for moving the pair of sandwiching portions in the width direction of the loop piece, and the sandwiching portion first control means are operated by the sandwiching portion first drive means. When the both end portions of the loop piece are sandwiched between the first member and the second member from above and below, the pressing portion control means that separates the pressing portion from the placement portion, and the pressing portion control means is the pressing portion. When the holding part is separated from the placement part, the pair of sandwiching parts are moved in the width direction of the loop piece by the sandwiching part second driving means to separate the loop piece from the placement part. When the control unit and the second clamping unit second control unit separate the loop piece from the placement unit by the second clamping unit driving unit, the second clamping unit moves the pair of clamping units to the loop piece. Move in the width direction of the A clamping unit third control means for supplying a piece to the sewing device, and the interval changing means is configured to supply the loop piece to the sewing device when the clamping unit third control means supplies the loop piece to the sewing device. The interval in the length direction may be shortened. The loop piece supply device reduces the distance in the length direction of the loop pieces of the pair of sandwiching portions when the pressing portion is separated from the placement portion. At this time, the loop piece having the convex shape bends in the length direction. The loop piece supply device of the loop piece supply device has a loop piece that bends in the length direction more than when the distance in the length direction of the loop pieces of the pair of clamping parts is reduced in a state where the pressing portion is not separated from the mounting portion. It can be reliably supplied to the sewing device.

The CPU 101 of the control unit 4 receives the instruction output from the loop piece supply device 2, and outputs an instruction to execute a process for sewing the both ends 86 and 87 of the loop piece 8 to the cloth 9 on the sewing machine 3.

ミシン3のCPU91は制御部4が出力した指示を受信し、ループ片8の両端部86、87の各々を布9に縫い付ける(S16)。詳細にはCPU91はミシンモータ98を駆動して縫い付ける。縫い付ける処理が終了した時、CPU91は駆動部9を駆動して上糸と下糸を切断する(S16)。図22に示す如く、ミシン3はループ片8の両端部86、87に点線で示す縫目151、152を形成する。縫目151、152は各々ループ片8の長さ方向88において押え82の先端部821、822の外側にある。CPU91は駆動部97を駆動して押え82を布9(針板77)から離間する。縫目151、152の間のループ片8は上方に凸となる撓みを維持する。凸の中心Cはループ片8の長さ方向88の中心Cと一致する。ミシン3のCPU91はS16の処理が終了した指示を制御部4に出力する。 The CPU 91 of the sewing machine 3 receives the instruction output from the control unit 4 and sews both ends 86 and 87 of the loop piece 8 to the cloth 9 (S16). Specifically, the CPU 91 drives the sewing machine motor 98 to sew. When sewing attaching process is completed, CPU 91 cuts the needle thread and bobbin thread by driving the drive unit 9 9 (S16). As shown in FIG. 22, the sewing machine 3 forms seams 151 and 152 indicated by dotted lines at both ends 86 and 87 of the loop piece 8. The stitches 151 and 152 are respectively outside the tip portions 821 and 822 of the presser 82 in the length direction 88 of the loop piece 8. The CPU 91 drives the drive unit 97 to separate the presser 82 from the cloth 9 (needle plate 77). The loop piece 8 between the stitches 151 and 152 maintains an upwardly convex bend. The convex center C coincides with the center C in the length direction 88 of the loop piece 8. The CPU 91 of the sewing machine 3 outputs to the control unit 4 an instruction for completing the process of S16.

ループ片供給装置2のCPU31は駆動部66を駆動して支持部51を供給位置から挟持位置に揺動する(S17)。CPU31はS18の処理が終了した指示を制御部4に出力する。制御部4のCPU101はミシン3からS17の処理が終了した指示を受信し、ループ片供給装置2からS17の処理を終了した指示を受信した時、縫製制御処理を終了する。   The CPU 31 of the loop piece supply device 2 drives the drive unit 66 to swing the support unit 51 from the supply position to the clamping position (S17). The CPU 31 outputs an instruction that the process of S18 is completed to the control unit 4. When the CPU 101 of the control unit 4 receives an instruction from the sewing machine 3 for completing the process of S17 and receives an instruction for completing the process of S17 from the loop piece supply device 2, the sewing control process is terminated.

The first members 42 and 47 correspond to the first member of the present invention. The second members 43 and 48 correspond to the second member of the present invention. A pair of clamping parts 41 and 46 are corresponded to a pair of clamping part of this invention. The cutting part 18 and the drive parts 26 and 27 correspond to the cutting part of the present invention. The CPU 31 that executes the processing of the drive unit 63 and S10 corresponds to the interval changing means of the present invention. The drive parts 61 and 62 are equivalent to the clamping part 1st drive means of this invention. The drive part 64 is equivalent to the clamping part 2nd drive means of this invention.

The CPUs 101 and 31 that execute the process of S7 function as the clamping unit second control unit of the present invention. The CPUs 101 and 31 that execute the process of S9 function as the clamping unit third control unit of the present invention.

ループ片供給装置2は一対の挟持部41、46が各々ループ片8の両端部86、87を挟持し(S5)、押圧部12が載置部11から離間した時(S6)、一対の挟持部41、46の長さ方向の間隔を縮める(S10)。図18に示す如く、S10の処理によりループ片8は長さ方向88において撓む。ループ片供給装置2は長さ方向に撓むループ片8をミシン3に供給する(S11)。ミシン3が長さ方向88に撓んだループ片8の両端部86、87を縫製した時、縫目151、152の間にベルト等の紐状部材を通すための隙間ができる。故にミシン3が長さ方向88に撓んだループ片8の両端部86、87を縫製した時、ミシン3が長さ方向に撓んでいないループ片の両端部を縫製した時に比べ、ループ片8はベルト等の紐状部材を通しやすい。即ちループ片供給装置2は従来に比べベルト等の紐状部材を通しやすいループ片8をミシン3に供給できる。   In the loop piece supply device 2, when the pair of holding portions 41 and 46 hold the both end portions 86 and 87 of the loop piece 8 (S 5), and the pressing portion 12 is separated from the mounting portion 11 (S 6), the pair of holding portions 41 and 46. The interval in the length direction of the portions 41 and 46 is reduced (S10). As shown in FIG. 18, the loop piece 8 bends in the length direction 88 by the process of S10. The loop piece supply device 2 supplies the loop piece 8 bent in the length direction to the sewing machine 3 (S11). When the sewing machine 3 sews both ends 86 and 87 of the loop piece 8 bent in the longitudinal direction 88, a gap is formed between the stitches 151 and 152 for passing a string-like member such as a belt. Therefore, when sewing both ends 86 and 87 of the loop piece 8 where the sewing machine 3 is bent in the length direction 88, the loop piece 8 is compared with when sewing machine 2 is sewn at both ends of the loop piece which is not bent in the length direction. Is easy to pass a string-like member such as a belt. That is, the loop piece supply device 2 can supply the loop piece 8 to the sewing machine 3 that is easier to pass a string-like member such as a belt than the conventional one.

ループ片供給装置2は押圧部が2連続帯状部材を押さえた時に連続帯状部材を切断する(S3)。故にループ片供給装置2はループ片の切断面が連続帯状部材の幅方向(前後方向)に対して歪むことを抑制できる。ループ片供給装置2はループ片の仕上がり品質の低下を抑制できる。本実施形態の如くS5において載置部11の載置面に垂直な方向において載置部11の載置面の位置と一対の挟持部41、46が各々挟持するループ片8の両端部86、87の位置が異なる時、ループ片8は両者の位置関係に応じた側に凸を形成して撓む。ループ片供給装置2は載置部11の載置面と垂直な方向における載置部11の載置面の位置と一対の挟持部41、46が挟持するループ片8の両端部86、87の位置を調整することによりループ片8が撓む方向を制御できる。図14、図15に示す如く、上下方向において載置部11の載置面の位置が一対の挟持部41、46が挟持するループ片8の両端部86、87の位置よりも押圧部12側にある時、ループ片8は押圧部12側に凸を形成して撓む。ループ片供給装置2はループ片8が撓む方向を載置部11に対し押圧部12側にできる。   The loop piece supply device 2 cuts the continuous strip-shaped member when the pressing portion presses the two continuous strip-shaped members (S3). Therefore, the loop piece supply apparatus 2 can suppress that the cut surface of the loop piece is distorted with respect to the width direction (front-rear direction) of the continuous strip-shaped member. The loop piece supply device 2 can suppress the deterioration of the finished quality of the loop piece. As in this embodiment, in S5, in the direction perpendicular to the placement surface of the placement portion 11, the position of the placement surface of the placement portion 11 and both end portions 86 of the loop piece 8 that the pair of sandwiching portions 41 and 46 sandwich, respectively. When the position of 87 is different, the loop piece 8 is bent by forming a convex on the side corresponding to the positional relationship between the two. The loop piece supply device 2 includes the positions of the placement surface of the placement portion 11 in the direction perpendicular to the placement surface of the placement portion 11 and the end portions 86 and 87 of the loop piece 8 sandwiched by the pair of sandwiching portions 41 and 46. The direction in which the loop piece 8 bends can be controlled by adjusting the position. As shown in FIGS. 14 and 15, the position of the mounting surface of the mounting portion 11 in the vertical direction is closer to the pressing portion 12 than the positions of both end portions 86 and 87 of the loop piece 8 held by the pair of holding portions 41 and 46. The loop piece 8 is bent by forming a convex on the pressing portion 12 side. The loop piece supply device 2 can set the direction in which the loop piece 8 bends to the pressing portion 12 side with respect to the placement portion 11.

一対の挟持部41、46は押圧部12が載置部11と離間した時、ループ片8の幅方向(前方)に移動する(S6、S7)。故にループ片供給装置2は押圧部12がループ片8を押さえた時にループ片8の幅方向に移動する時に比べ、ループ片8を円滑に載置部11から離間できる。押圧部12が載置部11から離間した時(S6)、一対の挟持部41、46のループ片8の長さ方向88の間隔が縮むと(S10)、凸を形成したループ片8は長さ方向88において更に撓む。ループ片供給装置2は長さ方向88に撓むループ片8を確実にミシン3に供給できる。   The pair of sandwiching portions 41 and 46 move in the width direction (forward) of the loop piece 8 when the pressing portion 12 is separated from the placement portion 11 (S6, S7). Therefore, the loop piece supply device 2 can separate the loop piece 8 from the mounting portion 11 more smoothly than when the pressing portion 12 presses the loop piece 8 and moves in the width direction of the loop piece 8. When the pressing portion 12 is separated from the placement portion 11 (S6), when the distance in the length direction 88 of the loop piece 8 of the pair of sandwiching portions 41 and 46 is reduced (S10), the loop piece 8 having a convex shape is long. Further bending in the vertical direction 88. The loop piece supply device 2 can reliably supply the loop piece 8 bent in the longitudinal direction 88 to the sewing machine 3.

ループ片供給装置2はループ片8を挟持する動作(S1〜S7)とループ片8をミシン3に供給する動作(S9〜S11、S13〜S15)を行う。故にループ片供給装置2ではループ片8を挟持する構成はループ片8をミシン3に供給する構成と互いに干渉しない必要がある。ループ片供給装置2の支持部51は軸53を中心に揺動できる。故にループ片供給装置2は支持部51を揺動できない時に比べ、載置部11、押圧部12、一対の挟持部41、46の構成、動作を簡略化できる。縫製システム1では、支持部51が挟持位置にある時、ミシン3は支持部51が供給位置にある時に比べ第二装置40と相対的に離間する。支持部51が挟持位置にある時、作業者は布9を交換する作業、所望の位置に配置する作業を行いやすい。故にループ片供給装置2は作業者の布9を配置する作業の作業性を向上できる。   The loop piece supply device 2 performs an operation of sandwiching the loop piece 8 (S1 to S7) and an operation of supplying the loop piece 8 to the sewing machine 3 (S9 to S11, S13 to S15). Therefore, in the loop piece supply device 2, it is necessary that the configuration for holding the loop piece 8 does not interfere with the configuration for supplying the loop piece 8 to the sewing machine 3. The support portion 51 of the loop piece supply device 2 can swing around the shaft 53. Therefore, the loop piece supply device 2 can simplify the configuration and operation of the placement unit 11, the pressing unit 12, and the pair of clamping units 41 and 46 compared to when the support unit 51 cannot swing. In the sewing system 1, when the support portion 51 is in the clamping position, the sewing machine 3 is relatively separated from the second device 40 as compared with when the support portion 51 is in the supply position. When the support portion 51 is in the clamping position, the operator can easily perform the work of replacing the cloth 9 and the work of placing the cloth 9 in a desired position. Therefore, the loop piece supply device 2 can improve the workability of the work of arranging the cloth 9 of the worker.

When the throat plate 77, the placement portion 11, and the pair of clamping portions 41 and 46 are arranged on the same straight line as in the prior art, the loop piece supply device 2 omits the support portion 51, the shaft 53, and the drive portion 66 as appropriate. Then, the process of S8 may be omitted.

押圧部12がループ片8の幅方向に移動できる時等には、S6の処理は省略してよい。ループ片供給装置2はループ片8を直接載置部11に供給する時等には供給部15、切断部18、駆動部23〜27を省略し、S1〜S3の処理を省略、変更してよい。ループ片供給装置2が備える駆動部21〜27、61〜66は各々モータ等の他のアクチュエータに適宜変更してよい。ループ片8の両端部86、87を挟持する一対の挟持部41、46の間隔を縮める処理(S10)は、S7の処理後且つS12の処理前であればよい。   When the pressing part 12 can move in the width direction of the loop piece 8, the process of S6 may be omitted. The loop piece supply device 2 omits the supply unit 15, the cutting unit 18, and the drive units 23 to 27 when supplying the loop piece 8 directly to the mounting unit 11, and omits or changes the processes of S1 to S3. Good. The drive units 21 to 27 and 61 to 66 included in the loop piece supply device 2 may be appropriately changed to other actuators such as a motor. The process (S10) for reducing the distance between the pair of holding parts 41 and 46 that hold the both ends 86 and 87 of the loop piece 8 may be performed after the process of S7 and before the process of S12.
