Patent ID: 7454824

Claim:
An apparatus for inserting a slide unit of a clamping head on a zipper bag comprising: a base frame ( 1 ); a vibration device ( 10 ), a track ( 11 ) and an installation device ( 2 ) installed on the base frame ( 1 ); wherein the installation device ( 2 ) includes a retaining seat ( 20 ); the retaining seat ( 20 ) includes a removing unit ( 3 ), an input unit ( 4 ) and a press unit ( 5 ), wherein said removing unit ( 3 ) includes a groove ( 30 ); a front side of said groove ( 30 ) having a notch ( 31 ) for receiving a clamping portion ( 91 ) of the zipper bag ( 9 ), wherein the closed clamping portion ( 91 ) of said zipper bag ( 9 ) can pass through said notch ( 31 ); a removing sheet ( 32 ) disposed within said groove ( 30 ) such that as said 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 can be placed therein; the input unit ( 4 ) including a push rod ( 40 ) positioned below the track ( 11 ) with said push rod ( 40 ) being used to push forward and install the slide unit ( 92 ) onto the zipper bag ( 9 ) so as to form an opening on the clamping portion ( 91 ); the press unit ( 5 ) being on one side of the input unit ( 4 ); the press unit ( 5 ) having two rolling wheels ( 50 ) and ( 51 ); and the two rolling wheels ( 50 ) and ( 51 ) being driven by two air pressure devices ( 52 ) and ( 53 ); wherein during assembly of the zipper bag, the slide unit ( 92 ) is positioned in the vibration device ( 10 ) such that the clamping portion ( 91 ) is installed in the groove ( 30 ) by passing through installation device ( 2 ), wherein the closed clamping portion ( 91 ) is opened by the removing sheet ( 32 ) in the groove ( 30 ); and the slide unit ( 92 ) is vibrated and guided by means of the vibration device ( 10 ) along the track ( 11 ), wherein the track ( 11 ) delivers the slide unit ( 92 ) to the input unit ( 4 ) wherein the push rod ( 40 ) pushes the slide unit ( 92 ) forward to be installed and to open the clamping portion ( 91 ) of the zipper bag ( 9 ), wherein subsequent to the slide unit ( 92 ) being installed, the air pressure devices ( 52 ) and ( 53 ) are moved upward and downward respectively to move rolling wheels ( 50 ) and ( 51 ) upward and downward, respectively, in order to increase a gap between the two rolling wheels allowing the slide unit ( 92 ) of the clamping head of the clamping portion ( 91 ) to pass through the gap; wherein the two air pressure devices ( 52 ) and ( 53 ) are moved back allowing the two rolling wheels ( 50 ) and ( 51 ) to move back to their original locations to press the opened clamping portion ( 91 ) to a closed state.
