Referring to fig. 1-2, fig. 1 is a front view of a seam position detection device according to an embodiment of the present invention;

FIG. 2 is a back view of the seam position detecting device provided in the embodiment of the present invention, which provides a seam position detecting device, including a lifting cylinder 1, a mounting block 2, a mounting plate 3, a swing arm 4, a roller 5 and a sensing switch 6, wherein the mounting plate 3 is fixed on the mounting block 2, the swing arm 4 is rotatably connected with the mounting plate 3, the sensing switch 6 is disposed on the mounting block 2 and located between the mounting block 2 and a first end of the swing arm 4, the sensing switch 6 is used for detecting the movement of the swing arm 4, the roller 5 is disposed at a second end of the swing arm 4, the lifting cylinder 1 is connected with the mounting block 2 and is used for driving the mounting block 2 to move vertically, so that the roller 5 is pressed on the seam material, when the roller 5 contacts with the seam position of the seam material, the swing arm 4 can be driven to swing relative to the mounting plate 3, which in turn triggers the inductive switch 6.

Specifically, lift cylinder 1 is used for ordering about installation piece 2 is along vertical motion, and then drives mounting panel 3 swing arm 4 reaches gyro wheel 5 is along vertical motion. For example, when sewing the cuff, begin to make by the seam position, when the round sewing is about to be accomplished, need detect the seam position, start lift cylinder 1 this moment, the telescopic link of lift cylinder 1 stretches out and orders about the vertical downstream of installation piece 2, drive through swing arm 4 gyro wheel 5 compresses tightly on the seam material, when gyro wheel 5 with the seam position contact of seam material, because the seam position is upwards protruding compared other positions, so make swing arm 4 relative mounting panel 3 takes place the swing, and then trigger inductive switch 6. When detecting the seam position back, lift cylinder 1 backward movement, the telescopic link withdrawal of lift cylinder 1 orders about the vertical upward movement of installation piece 2, through swing arm 4 drives gyro wheel 5 moves upward, is equivalent to restoring to the throne to wait for the detection of next seam position.

With continued reference to fig. 1 and 2, the seam position detecting device further includes a mounting seat 7, and the lifting cylinder 1 is fixed on a head of the sewing machine through the mounting seat 7. In this embodiment, the lifting cylinder 1 and the mounting base 7, and the mounting base 7 and the machine head can be connected through a threaded connection or the like. In addition, in the present embodiment, the mounting plate 3 is screwed to the mounting block 2.

Under the initial condition, swing arm 4 is vertical setting, works as gyro wheel 5 with during the seam position is detected, orders about swing arm 4 is relative mounting panel 3 swings, makes swing arm 4 is certain angle with vertical direction. In this embodiment, the swing arm 4 is hinged to the mounting plate 3 through a pin.

Preferably, the slot position detecting device further comprises a return spring (not shown in the figure), and two ends of the return spring are respectively connected to the swing arm 4 and the mounting block 2. Reset spring mainly used swing arm 4 resets, works as gyro wheel 5 with during the seam position contact of seam material, swing arm 4 is relative mounting panel 3 swings, makes swing arm 4 is certain angle with vertical direction, works as when lift cylinder 1 moves backward, swing arm 4 drives gyro wheel 5 moves up, and at this moment swing arm 4 can be in reset spring's elasticity effect resumes to vertical state down to wait for the detection of next seam position. In this embodiment, the return spring may be one, or may be a plurality of, and may be adjusted according to actual needs, and this application does not limit this.

With reference to fig. 1, the gap detection apparatus further includes an adjusting plate 8 disposed on the mounting plate 3, the adjusting plate 8 is at least partially disposed between the first end of the swing arm 4 and the mounting plate 3, and the adjusting plate 8 can move relative to the mounting plate 3 to adjust a distance from the first end of the swing arm 4 to the inductive switch 6. Through setting up regulating plate 8 can avoid under the initial condition the first end of swing arm 4 with inductive switch 6's distance undersize influence detects and when swing arm 4 resets with inductive switch 6 bumps.

The preferred, regulating plate 8 with the bar groove has been seted up to the correspondence on the mounting panel 3, seam position detection device still includes the fastener, the fastener screw in order regulating plate 8 with bar groove on the mounting panel 3 is in order to incite somebody to action regulating plate 8 is fixed on the mounting panel 3.

In this embodiment, the regulating plate 8 includes mutually perpendicular's first portion and second portion, the first portion be located swing arm 4's first end with between the mounting panel 3, the second portion with the mounting panel 3 is laminated mutually and is corresponded and seted up the bar groove. By moving the second part of the adjustment plate 8, the length of the first part extending out of the mounting plate 3 can be adjusted, and the distance from the first end of the swing arm 4 to the inductive switch 6 can be adjusted.

As a preferable example in the present embodiment, the inductive switch 6 is a proximity switch. In an initial state, the swing arm 4 is in a vertical state, the swing arm 4 is in an induction range of the proximity switch, when the roller 5 is in contact with the seam position, the swing arm 4 swings relative to the mounting plate 3 and is far away from the proximity switch, and the proximity switch sends a signal outwards at the moment to indicate that a circle of sewing is finished.

Of course, the inductive switch 6 may also be an optical switch or a magnetic switch, which is not limited in this application.

To sum up, the embodiment of the utility model provides a seam position detection device need examine the seam position, starts the lift cylinder is in order to order about the vertical downstream of installation piece, through the swing arm drives the gyro wheel compresses tightly on the seam material, works as the gyro wheel with during the seam position contact of seam material, because the seam position is compared other positions and is upwards protruding, so make the swing arm is relative the swing takes place for the mounting panel, and then triggers inductive switch. When detecting after the position is sewed up, the lift cylinder reverse operation, the telescopic link of lift cylinder withdraws and orders about the vertical upward movement of installation piece, through the swing arm drives the gyro wheel shifts up, is equivalent to and resets to wait for the detection of next position. Whole device simple structure, convenient to use and detection precision are high, can be applicable to the cuff of different styles, the effectual production efficiency that has improved.

The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
