[0002] As disclosed in the patent application with the application number 2019211793541 and the title of "A Loop for Tensile Connection Loop" filed by the applicant, the loop has a relatively reasonable structure and is very convenient to use. However, there is currently a lack of an automatic loop attaching machine and an automatic hanging tag card feeding machine that match it. In the existing work, manual labor is used to arrange the required hanging tag cards and stack them together, and then the hanging tag cards are sent to a manual loop attaching gun for loop attaching. The main problems of this working method are low automation, manual processing, and when multiple hanging tag cards need to be stacked, problems such as omission, incorrect order, and incorrect front and back sides are likely to occur, resulting in low production efficiency. Moreover, in the manual processing method, after long-term operation by workers, fatigue, hand fatigue, etc. are likely to occur, and it is very easy to make mistakes, and even the situation of being accidentally injured by the loop attaching gun may occur.

[0060] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0061] An automatic card feeding and collar attaching device includes the following equipment:

[0062] A device frame 1 to support the entire device;

[0063] A workbench 5, which is arranged at the front end above the device frame 1, and a collar attaching window 7 is provided on the workbench 5;

[0064] A collar attaching device 6, which is located below the workbench 5 and includes a collar gun 68 and a collar gun fixing device. The needle 66 of the collar gun 68 is vertically located at the collar attaching window 7;

[0065] A tag card feeding device 3, including a fixed base 31 and a plurality of tag card fixing devices arranged on the fixed base 31. The tag card fixing devices support the tag cards to be sucked;

[0066] A grasping device 4, which includes a manipulator base plate 41 and a plurality of manipulators arranged on the manipulator base plate 41. The manipulators adsorb and release the tag cards;

[0067] A manipulator driving device 2 is arranged above the device frame 1. The manipulator base plate 41 is fixed on the manipulator driving device 2. When the manipulator driving device 2 operates, it drives the manipulators to move back and forth between the tag card feeding device 3 and the collar attaching window 7.

[0068] In this embodiment, the collar attaching device 6 includes a vertically arranged gun plate 612, a mounting device for fixing the collar gun 68 on the gun plate 612, a collar attaching driving device for driving the collar gun 68 to act, and a tag card placement plate 65; the mounting device is arranged on one side of the gun plate 612 to fix the collar gun 68 on one side of the gun plate 612. The needle 66 of the collar gun 68 vertically extends upward from the upper end of the gun plate 612 and is located within the collar attaching window 7; the collar attaching driving device is arranged on the other side of the gun plate 612. The collar attaching driving device is connected with a firing switch rod 64, which is opposite to the wrench of the collar gun 68. When the collar attaching driving device drives the firing switch rod 64 to move up and down, the firing switch rod 64 can pull the wrench of the collar gun 68 to achieve the action of attaching the collar; the tag card placement plate 65 is located at the upper end of the gun plate 612.

[0069] In this embodiment, the installation device includes a collar gun seat plate 61 and a locking device 615. The collar gun seat plate 61 matches the shape of the handle end of the collar gun 68 and limits the collar gun 68 below and on the side, lifting the collar gun 68 upward, that is, the needle 66 of the collar gun 68 faces the upper end of the gun plate 612. The locking device 615 includes a locking column 613, a locking plate 611, a buffer block 69 and a locking nut 610. The locking column 613 is fixed on the collar gun seat plate 61. The locking plate 611 is connected to the upper end of the locking column 613 and can rotate around the locking column 613. The locking nut 610 is arranged at the other end of the locking plate 611, and a buffer block 69 is provided on the locking nut 610. When fixing, the buffer block 69 presses tightly on the gun body of the collar gun 68. This structure facilitates the disassembly and assembly of the collar gun, and is convenient for maintenance and replacement of the collar. The collar driving device is driven by a double cylinder, including a first firing cylinder 63 and a second firing cylinder 62. The two cylinders are fixed in series on one side of the gun plate 612. The cylinder body of the second firing cylinder 62 is fixed on the side of the gun plate 612. The end of the piston rod of the second firing cylinder 62 is fixedly connected to the cylinder body of the first firing cylinder 63 through a connecting plate 619. The end of the piston rod of the first firing cylinder 63 is fixedly connected to one end of the firing switch rod 64. The other end of the firing switch rod 64 crosses the gun plate 612 and is located above the wrench of the collar gun 68. The double cylinder method is used to improve the use efficiency of the cylinder. Because during the working process of the collar gun 68, its wrench has two working states. When the wrench is pressed down for the first time, the action is to cut the male head and female head from the rail frame and convey them upward in time. When the wrench is pressed down again for the second time, the action is that the male head needle 66 of the collar gun 68 presses the male head into the female head to realize the buckling of the collar. If these two steps are driven by one cylinder, it is easy to cause damage to the parts of the gun. Using two sections of cylinders can achieve the effect of extending the service life. Separating the cylinder and the gun body on both sides of the gun plate 612 can reduce the occupied volume and is also convenient for the disassembly and assembly of the collar gun 68. If they are set on the same side, it is not convenient for disassembly and assembly. A firing slot 618 is provided on the gun plate 612 corresponding to the up and down movement track of the firing switch rod 64. The tag cardboard placement plate 65 is L-shaped. Its upper end is horizontally arranged at the collar window 7 and is located beside the needle 66 of the collar gun 68. Its lower end is fixed on the gun plate 612. A sensor window 67 is provided on the tag cardboard placement plate 65. During the automatic collar process, a photoelectric switch will be set below the sensor window 67. This photoelectric switch is a photosensitive sensor, with the reference model CX-441, which is used to detect whether the cardboard has been taken away. After it is taken away, the manipulator will continue to send the tag cardboard over. If the cardboard has not been taken away, an alarm will be given within the set time.

[0070] In this embodiment, the tag cardboard fixing device includes a tag cardboard supporting device 311, a tag cardboard limiting device, and a thimble 36 located on a fixed base 31; the tag cardboard supporting device 311 includes a top plate 33 and an elastic lifting device 32. The top plate 33 is provided at the upper end of the elastic lifting device 32. The top plate 33 supports the tag cardboard, and the elastic lifting device 32 lifts the top plate 33 supporting the tag cardboard to a fixed height position above the fixed base 31; the tag cardboard limiting device is arranged around the tag cardboard supporting device 311 to limit the four sides of the tag cardboard; the thimble 36 is used to pass through the through hole of the tag cardboard to neatly position the tag cardboard at the through hole end.

[0071] In this embodiment, the tag paper limiting device includes a side limiting device and an end limiting device. The side limiting devices are symmetrically arranged on the left and right sides of the tag paper supporting device 311, namely the left limiting device 38 and the right limiting device 312. Each limiting device includes a column 35 and a column baffle 34 arranged inside the column 35. In the left limiting device 38, the column baffle 34 is arranged on the right side of the column 35, and in the right limiting device 312, the column baffle 34 is arranged on the left side of the column 35. The end limiting device includes a front end limiting device 310 and a rear end limiting device 37. The front end limiting device 310 includes a column 35 and a sliding pressing and clamping assembly arranged at the upper end of the column 35. The rear end limiting device 37 includes a column 35 and a pushing piece 323 arranged at the upper end of the column 35. The sliding pressing and clamping assembly includes a pressing and clamping mounting seat 317, a sliding pressing and clamping 316, a locking tongue 324 and a knob 315. The pressing and clamping mounting seat 317 is fixed at the top of the column 35. Multiple fixed sliding grooves are arranged at the end of the pressing and clamping mounting seat 317, and a locking tongue slideway is arranged in the middle of the pressing and clamping mounting seat 317. The sliding pressing and clamping 316 is fixed at the fixed sliding groove. The locking tongue 324 is arranged in the locking tongue slideway, and its end extends out from the sliding pressing and clamping 316 along the locking tongue slideway towards the top plate 33. One end of the locking tongue 324 extending out of the locking tongue slideway is stepped. One end of the pushing piece 323 facing the top plate 33 is also stepped, and the two are symmetrical to each other with the step surfaces facing the base. The ejector pin 36 is arranged at the front end of the top plate 33, between the top plate 33 and the tag paper limiting device; or the ejector pin 36 is directly arranged at the front end of the top plate 33. The lower end of the ejector pin 36 is fixed on the fixed base. A spring 319 is sleeved outside the ejector pin 36. The spring 319 at the ejector pin 36 can better align the tag papers neatly and prevent the tag papers from being stuck when being adsorbed. The sliding pressing and clamping 316 can move back and forth along the fixed sliding groove to finely adjust the position according to tag papers of different sizes. The structure among the sliding pressing and clamping 316, the locking tongue 324 and the knob 315 is an existing structure. Referring to the structure of an old-fashioned door lock, turning the knob 315 can control the locking tongue 324 to extend out or retract from the sliding pressing and clamping 316. The front end limiting device 310 and the rear end limiting device 37 limit the tag papers from the front and rear ends respectively. Because the tag papers have static electricity, they are likely to stick together in multiple sheets when being adsorbed, and the situation of adsorbing multiple sheets at the same time occurs. The steps at the ends of the locking tongue 324 and the pushing piece 323 can prevent the tag papers from being pushed out by the top plate 33. At the same time, the stepped shape can separate the edges of the tag papers pushed to the upper end, so that the suction cup 47 can only adsorb one tag paper at a time above the tag papers.

[0072] The described elastic lifting device 32 includes a guide rod 318, a guide rod seat 320, and a bushing locking block 322. The bushing locking block 322 is disposed above the fixed base, and the guide rod seat 320 is disposed below the fixed base 31 to clamp the fixed base 31. The lower end of the guide rod 318 sequentially passes through the bushing locking block 322, the longitudinal chute 313 on the fixed base 31, and the guide rod seat 320 from top to bottom and is fixedly connected to a hand-tightening nut 321. The upper end of the guide rod 318 is fixed with a top plate 33. A spring 319 is disposed outside the guide rod 318, and the upper and lower ends of the spring 319 respectively abut against the lower surface of the top plate 33 and the upper surface of the bushing locking block 322. The working principle of the elastic lifting device 32 is that when a tag cardboard is placed at the top plate 33, the guide rod 318 will be pressed down. When the tag cardboard at the top plate 33 is sucked away, under the action of the spring 319, the guide rod 318 will slowly rise, so as to ensure that the uppermost tag cardboard is pushed to the same height and is limited by the lock tongue 324 and the push piece 323 above. The guide rod seat 320 finally limits the rising height of the guide rod 318.

[0073] A cross mounting groove 39 is provided on the fixed base 31. A longitudinal chute 313 and a transverse chute 314 are provided in the cross mounting groove 39. The transverse chutes 314 are symmetrically disposed on the left and right sides of the longitudinal chute 313 and are perpendicular to the longitudinal chute 313.
