The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0048] See Figures 1 to 10 , in an embodiment of this application, an automatic lining feeding device for a patch pocket machine is provided, which includes a feeding unit 100, a shearing unit 200, and a lining feeding unit 300. The feeding unit 100 includes a winding disc 120, and a lining tape as a raw material is loaded on the winding disc 120. The winding disc 120 is connected to and follows the shearing unit 200 through a hanging rod 110, and while adapting to the position adjustment of the shearing unit 200, it can continuously supply the lining tape. After the lining tape is acted on by the cutter of the shearing unit 200, a lining is obtained, and the lining can be transferred to the next process by existing means.

[0049] The shearing unit 200 includes a support 220 and a cutter. The cutter includes a moving blade 240 and a fixed blade 230 that cooperate with each other. The support 220 is provided with a guiding hole 221, and the moving blade 240 slidably passes through the guiding hole 221. A first air cylinder 250 is installed on the support 220 and is in transmission cooperation with the moving blade 240. The first air cylinder 250 can also be driven by other means such as a motor or manually to adapt to more usage scenarios

[0050] The shearing unit 200 is provided with a conveying channel 210 for the lining tape to pass through. Along the horizontal direction, the conveying channel 210 has opposite front and rear sides, where the front side is the lining tape inlet 211 and the rear side is the lining tape outlet 212. The top side of the shearing unit 200 has a discharge port 213 communicating with the conveying channel 210, and the lining obtained by shearing with the cutter is output from the discharge port 213.

[0051] The gasket tape inlet 211 and the gasket tape outlet 212 in this embodiment are respectively located at the front side and the rear side of the shearing unit 200, but it is not strictly required to be arranged at the same height. The movement path of the gasket tape at the shearing unit 200 is generally forward and then out, avoiding the harsh requirements for pulling and tensioning when vertically conveying the gasket tape, and can better handle gasket tapes with different hardness levels.

[0052] The fixed knife 230 can be integrally or separately fixed to the support 220. The conveying channel 210 is located between the support 220 and the fixed knife 230. In the figure, the fixed knife 230 is located above the conveying channel 210. The fixed knife 230 is provided with a shearing hole 231 corresponding to the position of the guiding hole 221. The shearing hole 231 is open at the top side of the fixed knife 230 and serves as the discharge port 213. During operation, the moving knife 240 slides upward along the guiding hole 221 and enters the conveying channel 210, and cooperates with the fixed knife 230 to shear the gasket tape. The sheared part is the gasket and is pushed by the moving knife 240 to the discharge port 213 and then transferred to the process.

[0053] The remaining part of the gasket tape is removed from the conveying channel 210 through the gasket tape outlet 212. In order to better assist the continuous movement of the gasket tape and implement the guidance in the expected direction, a first guiding shaft 260 is installed on the support 220. The first guiding shaft 260 is located on one side of the gasket tape outlet 212 and is used to guide the gasket tape from the gasket tape outlet 212. In a preferred embodiment, the first guiding shaft 260 is arranged at the same height as the gasket tape outlet, and the movement resistance of the gasket tape is small, avoiding stress deformation of the gasket tape inside the conveying channel 210.

[0054] The gasket feeding unit 300 can continuously transfer the gasket tape and is arranged upstream or downstream of the shearing unit 200 according to the conveying direction of the gasket tape. In this embodiment, it is preferably arranged downstream and continuously transfers the gasket tape by a pulling method.

[0055] In one embodiment, the specific transmission method is to provide a pair of gasket feeding shafts arranged to drive the gasket tape to travel. The gasket feeding shafts include a driving shaft 330 and a driven shaft 340 that cooperate with each other. The gasket tape is clamped and driven by the driving shaft 330 and the driven shaft 340. Moreover, one of the improvements of this application is that the shearing unit 200 is installed on the gasket feeding unit 300 with adjustable position. The feeding unit 100 is connected to and follows the shearing unit 200. There are two sets of shearing units 200, and the adjustable position can change the spacing, adapt to more bag shape changes, and can achieve automatic control.

[0056] The surface of the driving shaft 330 can adopt a knurling process, and the surface of the driven shaft 340 can adopt methods such as adding rubber coating to increase the contact area and friction force to avoid the gasket tape from slipping. In addition, a second guiding shaft 315 is provided on the support seat 310, and the gasket tape output by the driving shaft 330 and the driven shaft 340 proceeds in a predetermined direction after passing through the second guiding shaft 315.

[0057] In one embodiment, the lining feeding unit 300 includes a support base 310. A guide rail 311 is provided on the support base 310. The shearing unit 200 is slidably fitted to the guide rail 311. In order to drive the shearing unit 200, a lead screw 320 and a power assembly 350 are provided on the support base 310. The power assembly 350 drives the lead screw 320 and the driving shaft 330 respectively. For example, the power assembly 350 includes a first motor 351 and a second motor 352. The first motor 351 and the second motor 352 can be linked to the driving shaft 330 and the driving lead screw 320 respectively through corresponding transmission mechanisms. The transmission mechanism can adopt various ways, such as a gear set 353, etc.

[0058] The lead screw 320 and the guide rail 311 cooperate with each other, which can accurately and stably guide the shearing unit 200 to adjust its position. In one embodiment, a specific installation method is provided. For example, a bracket 312 is slidably mounted on the guide rail 311. A guide seat 314 matching the guide rail 311 is provided at the bottom of the bracket 312. A nut seat 313 in threaded transmission cooperation with the lead screw 320 is also provided on the bracket 312. The shearing unit 200 is fixedly mounted on the bracket 312.

[0059] In one embodiment, the lead screw 320 is a double-threaded lead screw. The shearing unit 200 includes two sets, which are respectively installed on the positive thread section and the negative thread section of the double-threaded lead screw, and can achieve accurate synchronous reverse movement. In order to detect the position or calibrate the zero position of the first motor 351, etc., a sensor 400 for detecting the initial position of the shearing unit 200 is mounted on the support base 310. The sensor 400 itself can adopt conventional types, and detect the edge part or specific mark of relatively fixed parts such as the support 220 or the fixed knife 230 in the shearing unit 200 to obtain position information.

[0060] In one embodiment, in order to ensure that the driving shaft 330 and the driven shaft 340 are tightly pressed against each other and prevent the lining belt from slipping, a tensioning frame 360 is mounted on the support base 310. Both ends of the driven shaft 340 are rotatably mounted on the tensioning frame 360 and are in tensioning cooperation with the driving shaft 330.

[0061] A guide post 362 is fixed on the support base 310. The tensioning frame 360 is movably penetrated through the guide post 362. An elastic member 361 (such as a helical spring) is sleeved on the guide post 362. An anti-disengagement head is provided at the top of the guide post 362. Both ends of the elastic member 361 are abutted against the anti-disengagement head and the tensioning frame 360 respectively, so that the driven shaft 340 obtains a tensioning force for pressing against the driving shaft 330.

[0062] In one embodiment, to facilitate threading or replacing the gasket belt between the driving shaft 330 and the driven shaft 340, the driven shaft 340 can be slightly separated from the driving shaft 330 to overcome the limitation of the tensioning frame 360. In this embodiment, lifting shaft frames 370 are rotatably sleeved at both ends of the driven shaft 340. By applying force to the lifting shaft frames 370, the driven shaft 340 can be lifted as a whole to overcome the action of the elastic member 361. To facilitate automated control, a second cylinder 371 for driving the lifting shaft frames 370 is installed on the support base 310. The piston rod of the second cylinder 371 extends upward and has a jacking column 372 at its top. Lifting shaft frames 370 are provided at both ends of the driven shaft 340, and the two lifting shaft frames 370 are connected by a transmission cross bar 373. The jacking column 372 acts on the transmission cross bar 373, and then the lifting shaft frames 370 drive the driven shaft 340 to separate from the driving shaft 330. The jacking column 372 can also be driven in other ways. In this embodiment, a linear reciprocating motion is adopted in terms of the motion mode, but a swinging motion or other ways can also be adopted.

[0063] Another embodiment of the present application also provides a pocket attaching machine with the automatic gasket feeding device of the above embodiments. Other parts of the pocket attaching machine can be implemented in combination with the prior art.

[0064] In the initial state of the automatic gasket feeding device of the pocket attaching machine of the present application: the moving knife 240 retracts into the guiding hole 221 to avoid the transmission channel 210, the driven shaft 340 in the gasket feeding unit 300 is pressed against the driving shaft 330, the sensor 400 is in the extinguished state, and each motor is in the stopped working state. After starting the machine, manually or automatically return to zero. First, the driven shaft 340 can be lifted, and the two sets of shearing units 200 are each driven back to the origin position by the lead screw 320. The sensor 400 can detect its in-place signal. Then, according to the width of the pocket on the pattern, the widths on both sides of the pocket are measured, and a signal is sent to the second motor 352. The two sets of shearing units 200 are driven to the predetermined position by the lead screw 320.

[0065] When loading the gasket, first lift the driven shaft 340 away from the driving shaft 330, lead out the gasket belt feeding unit 100 through the transmission channel 210, bypass the first guiding shaft 260, then pass through between the driven shaft 340 and the driving shaft 330, and finally wind around the second guiding shaft 315. The corresponding driven shaft 340 falls back and clamps the gasket belt with the driving shaft 330.

[0066] During normal sewing, the driving shaft 330 is driven and cooperates with the driven shaft 340 to drive the gasket belt to move back and forth. When the gasket belt moves a specified distance, it pauses. The moving knife 240 moves upward to punch the gasket belt, and it is output from the discharge port 213. Subsequently, the gasket can be sent to the specified position by using the gasket feeding mechanism. After punching, the moving knife 240 resets, and the gasket belt continues to move, circulating in sequence.

[0067] The automatic lining feeding device of the present application for patch pocket machines reasonably arranges the conveying channel. The lining feeding method is from front to back, which will not be affected by the too soft lining belt. The motor control is adopted to make the lining feeding tension uniform, and the lining feeding distance can be automatically adjusted, eliminating the risk of breaking the lining cloth.

[0068] The lining belt can reserve an automatic detection signal, and a corresponding feeding sensor can be configured. When the feeding sensor cannot detect the lining belt, an alarm can be triggered to remind to change the lining belt.

[0069] The two sets of shearing units move synchronously and reversely, which can be linked with width adjustment, with accurate position. It is more suitable for a full-automatic system, which can reduce manual participation and improve production efficiency.

[0070] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved.

[0071] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
