The upper layer sewing template 11 is in the working position, the lower layer sewing template 21 is in the die-changing position as an example, and the working principle of the utility model is explained as follows by combining with the figure 5 and the figure 6:
when the upper layer sewing template 11 is in the working position, the first cylinder 42 extends or retracts to drive the first hook 43 to rotate around the first rotating shaft 44, so as to lock or release the first lock column 13, and lock or release the upper layer sewing template 11 in the working position. For example: in normal operation, the first cylinder 42 extends out to lock the first lock column 13; when the upper layer sewing template 11 needs to be replaced, the first air cylinder 42 retracts, the first lock column 13 is loosened, and the upper layer supporting plate 12 can be translated to the mould replacing position through the first telescopic device. Therefore, the movement of the upper layer supporting plate 12 or the lifting supporting plate 31 is not influenced, namely the translation of the upper layer supporting plate 12 to the direction of the mold changing position far away from the working position is not influenced, or the descending of the lifting supporting plate 31 is not influenced.
With the retraction or extension of the second cylinder 50, the second hook 52 is driven to rotate around the second rotating shaft 53, so as to lock or unlock the second lock cylinder 23, and the lower layer sewing template 21 is locked or unlocked. For example: when the lower layer sewing template 21 needs to be replaced, the second locking device 50 is loosened, a worker can replace the lower layer sewing template 21 on the template replacing supporting plate 22, and after the replacement is finished, the second locking device 50 locks the lower layer sewing template 21 on the template replacing supporting plate 22.
When the lower sewing template 21 is moved on the lifting platform by the second telescopic device, the second locking device 50 releases the two second locking columns 23, then the lifting platform is lifted to lift the lower sewing template 21 to be flush with the upper platform, and then the first locking device 40 locks the two second locking columns 23 on the lower sewing template 21, so that the lower sewing template 21 can move along the XY axis direction along with the workbench of the sewing machine to finish the sewing work.
In this embodiment, the driving element in the lifting device 31, the first and second locking devices, the first and second telescoping devices is a cylinder, but the utility model discloses the scheme is not limited to adopt the cylinder to realize flexible or lift function, can also adopt other modes such as pneumatic cylinder or motor drive's screw nut, rack and pinion, link mechanism to realize.
The utility model discloses an upper sewing template 11 and lower floor sewing template 21 can alternate use, and when one of them sewing template was in the work position, another sewing template of removable was as reserve, and when needs used reserve sewing template, only need with reserve sewing template move the work position can, simple structure, convenient to use, the retooling is efficient, and the sewing machine can not be in non-operating condition for a long time, increases work efficiency.
Further optimally, two sliding grooves are symmetrically formed in two opposite side walls of the upper layer workbench 10, two sides of the upper layer supporting plate 12 are respectively arranged in the two sliding grooves, one end of the first telescopic device is fixed to the die changing frame or the sewing machine frame, the other end of the first telescopic device is fixed to the upper layer supporting plate 12, and therefore the upper layer supporting plate 12 moves in the sliding grooves along with the extension and retraction of the first telescopic device, and the smoothness of the upper layer supporting plate 12 in the moving process can be increased.
In order to avoid the sewing template to change the placing position due to inertia factors in the moving process, the lock column on the sewing template can not be smoothly matched with the first hook 43 or the second hook 52, and a magnetic attraction device can be arranged at the bottoms of the upper layer supporting plate 12, the die changing supporting plate 22 and the lifting supporting plate 31, wherein the magnetic attraction device consists of a plurality of electromagnetic coils, so that the occupied space is reduced, and the influence on the normal movement of the upper layer supporting plate 12 and the lifting supporting plate 31 is avoided. The magnetic attraction device can ensure the correct positions of the first lock column 13 and the second lock column 23 after the sewing template is installed, so that the magnetic attraction device can be smoothly matched with the first hook 43 or the second hook 52 to realize locking.
In this scheme, lift cross retooling mechanism and realize full automatic operation through control system, according to making up the process, control corresponding executive component and work of mutually supporting, if: controlling the lifting device 31 to lift, controlling the first locking device 40 and the second locking device 50 to lock or unlock, controlling the first telescopic device and the second telescopic device to telescope, and the like.
In this scheme, still be equipped with the camera on retooling frame 200 or the sewing machine for whether detect sewing template style or mounted position are correct. According to the sewing process, the pattern and the information of the sewing template corresponding to each process can be preset in the control system, after the sewing template moves to the working position, the sewing template at the working position is identified to be consistent with the sewing template information of the corresponding process stored in the control system through the camera, if the sewing template information is consistent, the sewing template normally works, if the sewing template information is inconsistent, an alarm is sent out to remind a worker of replacing the sewing template again, and the loss caused by misoperation of the worker can be effectively avoided.
