DETAILED DESCRIPTION OF THE INVENTION
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to FIG. 3, the structure of the present invention is illustrated. In the present invention, a vibration device 10, a track 11 and an installation device 2 is installed on a base frame 1. Referring to FIGS. 4, 5, and 6, the installation device 2 is installed with a retaining seat 20. The retaining seat 20 is installed with a removing unit 3, an input unit 4 and a press unit 5. Referring to FIGS. 7A, 7B, and 7C, the removing unit 3 is installed with a groove 30. A front side of the groove 30 has a notch 31 for receiving a clamping portion 91 of a zipper bag 9. The closed clamping portion 91 of the zipper bag 9 can pass through the notch 31. A removing sheet 32 is installed in the groove 30. As the removing sheet 32 is removed by the closed clamping portion 91, an opening 90 of the zipper bag 9 is formed so that a slide unit 92 of a zipper clamping head is placed therein. The input unit 4 is installed below the track 11. The input unit 4 is installed with a push rod 40. The push rod 40 is used to push the slide unit 92 to the zipper bag 9 so as to form an opening on the clamping portion 91. The press unit 5 is on the one side of the input unit 4. The press unit 5 has two rolling wheels 50 and 51. The two rolling wheels 50 and 51 get moving by two air pressure devices 52 and 53.
In assembling, referring to FIGS. 3 to 9, the slide unit 92 is installed into the vibration device 10 firstly. The clamping portion 91 of the zipper bag 9 is installed in the groove 30 of the removing unit 3 by passing through installation device 2. The closed clamping portion 91 is opened by the removing sheet 32 in the groove 30 so as to the slide unit 92 capable of being installed. Then, by use of the vibration device 10, the slide unit 92 is vibrated and guided to the track 11 so as to deliver thereof in order. The track 11 delivers the slide unit 92 of clamping head to the input unit 4 of the installation device 2. By use of moving the push rod 40 of the input unit 4, the slide unit 92 of the clamping head is pushed forwards and installed at opening the clamping portion 91 of the zipper bag 9.
When the slide unit 92 of the clamping head is installed, the air pressure device 52 of the press unit 5 is upward to get the rolling wheel 50 moving upwards (referring to FIGS. 8 and 9). The other air pressure device 53 is downward to get the other rolling wheel 51 moving downwards so that the gap between the two rolling wheels 50 and 51 is increased. The slide unit 92 of the clamping head on the clamping portion 91 is available to pass through the gap. After the slide unit 92 of the clamping head passed through the gap between the rolling wheel 50 and rolling wheel 51, the two air pressure devices 52 and 53 return back so as to get the two rolling wheel 50 and 51 moving back to the original locations. By use of rolling the two rolling wheels 50 and 51 to press the opening clamping portion 91, the previously removing clamping portion 91 is in the closed state. Thereby, the procedure of assembly is continuous automatically so that the slide unit 92 of the clamping head is installed at the clamping portion 91 of the zipper bag 9 in quite short time. The assembly is convenient and fast so as to reduce manufacture cost and enhance productivity. Therefore, the present invention is economic and efficient.
The present invention is thus described, and it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
