JP 2011-161061 A JP 2011-030897 A JP 2010-252933 A

However, the sequin supply device 90 of Conventional Example 1 has the following problems [1] to [3].
[1] Since the movable knife 92 is directly hit by the pressing portion 82 of the needle bar 80 and pushed down, the movable knife 92 is easily worn. Therefore, the movable knife 92 must be replaced early.
[2] As shown in FIG. 8 (b), when using a large-diameter sequin S, the space between the needle bar 80 and the movable knife 92 becomes wide, so that the pressing portion 82 of the needle bar 80 is pressed. Cannot reach the movable knife 92, and the sequin S cannot be separated.
[3] The pressing portion 82 of the needle bar 80 that is pushed down by hitting the movable knife 92 is likely to be worn. Therefore, early replacement of the needle bar 80 and the needle stopper 81 is unavoidable.

  Therefore, in the needle bar 80, in order to solve the above problem [2], the needle stopper 81 is provided with a pressing portion 82 ′ that protrudes long toward the movable knife 92 as in the conventional example 2 shown in FIG. Some are also available. According to the second conventional example, as shown in FIG. 9B, when the large-diameter sequin S is used, even when the distance between the needle bar 80 and the movable knife 92 is wide, the push-down portion that protrudes long is used. The movable knife 92 can be pushed down by 82 '. However, the moment applied to the pressing portion 82 'increases, and the pressing portion 82' and the needle bar 80 are likely to bend.

  Therefore, the first purpose is to prevent the movable knife from being worn, and the second object is to shorten the protruding length of the pressing portion while being able to cope with a case where the distance between the needle bar and the movable knife is wide. The third object is to prevent wear of the pressing part.

  In order to achieve the above first and second objects, a sequin feeding device of the present invention includes a feeding device that feeds the tip of a sequin tape to a needle drop point, and a separation mechanism that separates the sequin from the tip of the sequin tape. In the sequin supply apparatus configured to include the movable knife and the movable knife, the separation mechanism is provided so as to be exchangeable at a position separated from the movable knife toward the needle bar, and is pushed down by the pressing part of the needle bar when the needle bar is lowered. A pressing member and a power transmission mechanism for driving the movable knife by transmitting the force received by the pressed member from the pressing part to the movable knife, and driving the movable knife from the tip of the sequin tape. It is characterized by separating sequins.

  This is because, with such a configuration, the movable knife cannot be pushed down by the pressing portion, and thus wear of the movable knife is prevented. This is because the pressed member can be replaced when worn. Moreover, it is because the protrusion length of a press part can be shortened rather than the case where a movable knife is pushed down by a press part.

  The movement of the pressed member when the needle bar is lowered is not particularly limited, and examples thereof include downward rotation and downward parallel movement. Further, the movement of the movable knife when the needle bar is lowered is not particularly limited, but examples include downward rotation and downward parallel movement.

  The relative position between the pressed member and the movable knife may be fixed, but even if the position of the movable knife is changed according to the sequin size, the pressed member may be arranged at a position where the pressed member is pushed down by the pressing unit. It is preferable that the relative position between the pressed member and the movable knife can be changed so as to be able to. That is, when the movable knife is moved closer to the needle bar, such as when the sequin size is small, the pressed member is also moved closer to the movable knife, and when the movable knife is moved away from the needle bar, such as when the sequin size is large, This is because the pressed member can be arranged at a position where the pressed member can be always pushed down by the pressing portion even when the sequin size changes by separating the pressed member from the movable knife.

  Although the aspect of a power transmission mechanism is not specifically limited, The following aspect is illustrated. In other words, the power transmission mechanism supports the movable knife so that it cannot be rotated relative to the knife, and can rotate together with the movable knife. It is the aspect comprised including the rotation shaft rotated with a member, and the transmission part which rotates a female shaft with a movable knife by transmitting the rotational force of a rotation shaft to a female shaft.

In the aspect of the power transmission mechanism described above, the aspect in which the relative position between the pressed member and the movable knife can be changed is not particularly limited, but the following [i] [ii] is exemplified.
[I] A mode in which the relative position between the pressed member and the movable knife can be changed by being configured so that the position of the rotation shaft can be adjusted with respect to the transmission unit.
[Ii] A mode in which the position of the pressed member can be adjusted with respect to the rotation shaft, so that the relative position between the pressed member and the movable knife can be changed.

  Although only one of the aspects [i] and [ii] may be employed, it is preferable to employ both aspects. This is because the relative position between the pressed member and the movable knife can be changed in a wider range.

  Although the specific aspect of a transmission part is not specifically limited, The following aspect is illustrated. That is, the transmission part is attached to the female shaft so as not to rotate relative to the female shaft, and can be rotated together with the female shaft and the movable knife. It is the aspect comprised including the transmission member which presses a to-be-transmitted member by rotating with a pressing member and a rotation shaft, and rotates a to-be-transmitted member with a female shaft and a movable knife.

Although the aspect of a transmission member and a to-be-transmitted member is not specifically limited, The following aspect [i] [ii] is illustrated.
[I] A mode in which the member to be transmitted is in contact with the transmission member so as to be slidable.
[Ii] A mode in which one of the transmitted member and the transmitting member includes a roller, and the roller is in contact with the other of the transmitted member and the transmitting member so as to be rotatable.

  In order to achieve the above third purpose (prevention of wear of the pressed portion), the Vickers hardness of the portion of the pressed member that contacts the pressed portion is lower than the Vickers hardness of the pressed portion of the pressed portion that contacts the pressed member. It is preferable. This is because wear of the pressing portion can be reduced by making the pressed member softer than the pressing portion. This is because the pressed part can be replaced even if worn. Furthermore, it is preferable that the Vickers hardness of the portion contacting the pressed portion of the pressed member is lower than the Vickers hardness of the upper end portion of the movable knife. This is because the wear of the pressing portion can be reduced as compared with the case where the movable knife is pushed down by the pressing portion.

  According to the present invention, since the member to be pressed is pushed down by the pressing part of the needle bar, the movable knife is not pushed down by the pressing part, thereby preventing the movable knife from being worn. On the other hand, although the pressed part is worn, the pressed member is provided so as to be replaceable, so that it can be replaced when worn. Further, since the member to be pressed is provided at a position away from the movable knife toward the needle bar, the protruding length of the pressing part can be made shorter than when the movable knife is pushed down by the pressing part.

  When the needle bar 80 is lowered, the pressed member 25 is rotated about the rotation shaft 35 by the left end portion being pushed down by the pressing part 82 of the needle bar 80. Further, the Vickers hardness of the portion that contacts the pressed member 82 of the pressed member 25 is lower than the Vickers hardness of the portion that contacts the pressed member 25 of the pressed member 82 and the Vickers hardness of the upper end portion of the movable knife 21. It is lower than this.

[Power transmission mechanism 30]
The power transmission mechanism 30 is a mechanism that drives the movable knife 21 by transmitting the force received by the pressed member 25 from the pressing portion 82 to the movable knife 21. The power transmission mechanism 30 includes a female shaft 31, a rotation shaft 35, and a transmission unit 40 which will be described below.

  The female shaft 31 is a shaft extending in the front-rear direction, and is inserted into a female shaft support hole 8 b that penetrates from the mounting hole 8 a of the frame 8 to the front surface of the frame 8, thereby penetrating the front portion of the frame 8. And is attached to the frame 8 so as to be rotatable. The female shaft 31 pivotally supports the right end of the movable knife 21 at the front end so as not to be relatively rotatable. Therefore, the female shaft 31 can be rotated together with the movable knife 21. A notch 32 extending in the front-rear direction is provided at the rear portion of the female shaft 31, and the cross-sectional shape of the female shaft 31 in the portion where the notch 32 is provided is substantially D-shaped. ing.

  The rotation shaft 35 is a shaft extending in the front-rear direction, and is inserted into a rotation shaft support hole 8c penetrating from the attachment hole 8a of the frame 8 to the front surface of the frame 8 above the female shaft support hole 8b. The frame 8 is rotatably attached to the frame 8 so as to penetrate the front portion of the frame 8 above the female shaft 31. The rotation shaft 35 pivotally supports the right end portion of the pressed member 25 at the front end portion so as not to be relatively rotatable. Therefore, the rotation shaft 35 rotates together with the pressed member 25 when the needle bar 80 is lowered. Further, a notch 36 extending in the front-rear direction is provided at the rear portion of the rotation shaft 35, and the cross-sectional shape of the rotation shaft 35 at the portion where the notch 36 is provided is substantially D-shaped. It has become.

  The transmission unit 40 rotates the female shaft 31 together with the movable knife 21 by transmitting the rotational force of the rotating shaft 35 to the female shaft 31. The transmission unit 40 includes a transmission member 41 and a transmission member 45 described below.

  The transmitted member 41 is a member extending in the vertical direction, and a lower end portion thereof is attached to the rear portion of the female shaft 31 via the attachment portion 42 so that the position thereof can be adjusted in the front-rear direction. Therefore, the position of the female shaft 31 and the movable knife 21 can be adjusted in the front-rear direction with respect to the transmitted member 41 by adjusting the mounting portion 42. The mounting portion 42 includes a shaft hole 42a that penetrates the transmitted member 41 in the front-rear direction and the rear portion of the female shaft 31 is inserted, and a female screw hole that extends from the right side surface of the transmitted member 41 to the shaft hole 42a. 42 b and a screw 42 c screwed into the female screw hole 42 b and having a tip pressed against the notch 32 of the female shaft 31. The upper right side surface of the transmitted member 41 is slidably in contact with the upper left side surface of the transmission member 45.

  The transmission member 45 is a member extending in the vertical direction, and a lower end portion thereof is attached to the rear portion of the rotation shaft 35 via the attachment portion 46 so that the position of the transmission member 45 can be adjusted in the front-rear direction. Therefore, the relative position between the pressed member 25 and the movable knife 21 is changed in the front-rear direction by adjusting the position of the rotating shaft 35 and the pressed member 25 with respect to the transmission member 45 by adjusting the mounting portion 46. It can be changed to. Therefore, even if the position of the entire sequin supply device 1 is changed in the front-rear direction by the frame position adjustment mechanism 9 so that the movable knife 21 is at an appropriate position according to the size of the sequin S, the pressed member 25 does not transmit this transmission. It can be arranged at a position where the pressing portion 82 is pushed down by adjusting the mounting portion 46 of the member 45. The mounting portion 46 includes a shaft hole 46a that penetrates the transmission member 45 in the front-rear direction and is inserted through the rear portion of the female shaft 31, and a female screw hole 46b that penetrates from the right side surface of the transmission member 45 to the shaft hole 46a. The screw 46c is screwed into the female screw hole 46b and the tip is pressed against the notch 36 of the rotating shaft 35. When the needle bar 80 is lowered, the transmission member 45 rotates together with the pressed member 25 and the rotation shaft 35, so that the right side surface of the upper part of the transmission member 41 is pressed to the left to transmit the transmission member 41. Is rotated together with the female shaft 31 and the movable knife 21.

  The transmission member 45 is provided with a holding mechanism 47 that holds the position of the transmission member 45 in the front-rear direction with respect to the frame 8. The holding mechanism 47 is fitted to the rotation shaft 35 and is interposed between the front inner peripheral surface of the mounting hole 8a and the front surface of the transmission member 45, and presses the transmission member 45 rearward. And a collar or washer 47b that is externally fitted to the rotary shaft 35 and interposed between the rear inner peripheral surface of the mounting hole 8a and the rear surface of the transmission member 45.

[Return mechanism 50]
The return mechanism 50 is a mechanism for reversely rotating the movable knife 21, the pressed member 25, and the power transmission mechanism 30 to return to the original position when the needle bar 80 is raised. A spring 51 and a stopper 55 are included. The return spring 51 is a torsion coil spring that is externally fitted to the female shaft 31 and interposed between the front inner peripheral surface of the mounting hole 8 a and the front surface of the transmitted member 41. One end of the return spring 51 is in contact with the left side surface of the frame 8, and the other end is inserted into an insertion hole 43 provided in the transmitted member 41. The stopper 55 is attached to the right side surface of the frame 8 so as to straddle the mounting hole 8 a in the front-rear direction, and comes into contact with the upper right side surface of the transmission member 45.

  Next, the case where the sequin S is cut off from the front end portion of the sequin tape T using the sequin supply device 1 of the present embodiment will be described below.

[1] When lowering the movable knife 21 From the state where the needle bar 80 shown in FIGS. 3 (a) and 4 (a) is raised, as shown in FIGS. 3 (b), 4 (b) and 4 (c), When the needle bar 80 is lowered, the pressing portion 82 pushes down the left end portion of the pressed member 25. As a result, the pressed member 25 rotates together with the rotation shaft 35 and the transmission member 45. At this time, the transmission member 45 presses the transmitted member 41 in contact therewith. As a result, the transmitted member 41 rotates together with the female shaft 31 and the movable knife 21. As a result, the left portion of the movable knife 21 descends and the sequin S is separated from the tip of the sequin tape T.

[2] When raising the movable knife 21 From the state where the needle bar 80 shown in FIGS. 3 (b), 4 (b) and 4 (c) is lowered, the pressing part 82 is also raised when the needle bar 80 is raised. Thereby, the transmitted member 41 rotates backward together with the female shaft 31 and the movable knife 21 by the restoring force of the return spring 51. At this time, the transmitted member 41 presses the transmitting member 45 in contact in the direction opposite to [1]. Thereby, the transmission member 45 rotates backward together with the rotation shaft 35 and the pressed member 25. The position where the transmission member 45 abuts on the stopper 55 and stops is the standby position. Thereby, the left part of the movable knife 21 and the left part of the pressed member 25 are raised to the original positions.

  Then, by repeating the operations [1] and [2], the sequins S, S... Are continuously separated from the front end portion of the sequin tape T.

Next, how the sequin tape T is changed to a different size will be described below.
[1] First, the guide 16 is replaced with an appropriate one that matches the size of the sequin tape T.
[2] Next, as shown in FIG. 5 (a), the screw 46c of the transmission member 45 is loosened, and then the rotating shaft 35 is retracted rearward as necessary to move the pressed member 25 backward. Evacuate.
[3] Next, by rotating the frame position adjusting screw 9c and displacing the entire sequin supply device 1 in the front-rear direction as shown in FIG. 5A, the movable knife 21 is made the size of the sequin tape T. Move to the appropriate position.
[4] Next, as shown in FIG. 5 (b), the rotation shaft 35 is moved in the front-rear direction with respect to the transmission member 45 so that the pressed member 25 is pushed down by the pressing portion 82 of the needle bar 80. After moving to the position, the screw 46 c of the transmission member 45 is tightened again to fix the rotation shaft 35 to the transmission member 45.

According to the present invention, the following effects [A] to [G] can be obtained.
[A] Since the pressed member 25 is pushed down by the push-down portion 82 of the needle bar 80, the movable knife 21 is not pushed down by the push-down portion 82, thereby preventing the movable knife 21 from being worn. Therefore, the life of the movable knife 21 is extended. On the other hand, the pressed member 25 is worn, but the pressed member 25 is provided so as to be replaceable, so that it can be replaced when worn. Since the pressed member 25 is less expensive than the movable knife 21 and easy to replace, the cost and labor can be saved compared to replacing the movable knife 21.

[B] Since the pressed member 25 is provided at a position away from the movable knife 21 forward (on the side of the needle bar 80), the protruding length of the pressing part 82 is longer than when the movable knife 21 is pushed down by the pressing part 82. Can be shortened. Therefore, a large needle sequin S can be handled with the normal needle bar 80 without using a needle bar with a dedicated push-down portion having a long protruding length. Therefore, the protrusion length of the pressing part 82 of the needle bar 80 becomes longer, so that the problem that the pressing part 82 and the needle bar 80 are curved can be prevented.

[C] As shown in FIG. 6A, when the sequin feeder S is moved close to the front needle bar 80 by the frame position adjusting mechanism 9 such as when the size of the sequin S is small, the pressed member 25 is also moved close to the rear movable knife 21 by adjusting the mounting portion 46 of the transmission member 45 and the sequin feed is performed by the frame position adjusting mechanism 9 when the size of the sequin S is large as shown in FIG. When the entire apparatus 1 is moved backward from the needle bar 80, the size of the sequin S is changed by moving the pressed member 25 forward from the movable knife 21 by adjusting the mounting portion 46 of the transmission member 45. Even in this case, the pressed member 25 can always be disposed at a position where the pressed member 82 can be pushed down.

[D] In addition to being able to adjust the position of the rotation shaft 35 in the front-rear direction with respect to the transmission member 45 by the attachment portion 46 of the transmission member 45, the attachment portion 26 of the pressed member 25 can also be rotated as necessary. Since the position of the pressed member 25 can be adjusted in the front-rear direction with respect to the shaft 35, the position of the pressed member 25 can be adjusted within a wider range in the front-rear direction. Therefore, it becomes possible to deal with sequins S in a wide range of sizes. Specifically, in this embodiment, the sequin S having a diameter of 2 to 25 mm can be handled.

[E] Since the Vickers hardness of the part that contacts the pressed member 82 of the pressed member 25 is lower than the Vickers hardness of the part that contacts the pressed member 25 of the pressed part 82, wear of the pressed part 82 is reduced. Can do. Further, since the Vickers hardness of the portion that comes into contact with the pressing portion 82 of the pressed member 25 is lower than the Vickers hardness of the upper end portion of the movable knife 21, the pressing portion 82 is lower than when the movable knife 21 is pushed down by the pressing portion 82. Wear can be reduced. On the other hand, the pressed member 25 is worn as shown in the above [A]. However, the pressed member 25 is provided so as to be replaceable, and can be replaced when worn.

[F] Since the holding mechanism 47 is provided, the position of the transmission member 45 in the front-rear direction with respect to the frame 8 is maintained even during the operation of adjusting the position of the rotation shaft 35 in the front-rear direction with respect to the transmission member 45. Therefore, it is easy to adjust the position of the rotation shaft 35 in the front-rear direction with respect to the transmission member 45.

In addition, this invention is not limited to the said Example, In the range which does not deviate from the meaning of invention, it can change suitably and can be actualized.
[Modification 1] The sequin supply device 1 of the embodiment may be provided in the opposite direction.
[Modification 2] Instead of slidably contacting the upper left side surface of the transmission member 45 with the upper right side surface of the member 41 to be transmitted, the transmission member 45 can be changed like a sequin supply device 1b shown in FIG. A roller 49 may be provided at the upper left end portion, and the roller 49 may be in contact with the right side surface of the upper portion of the transmitted member 41 so as to be rotatable. Thereby, the sliding resistance between the transmission member 45 and the transmitted member 41 can be reduced, and wear can be prevented.
