DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawing and initialed from FIGS. 2, 3 and 4, the combination of two machine for making a cap of containers of the present invention comprises a forming machine 100 connected with a cutting machine 200 by a transferring disk 16. The forming machine is functioned to receive the half-finished caps 1 and transferring the formed cap 2 to the cutting machine for making breaking-line on the cap 1′. The cutting machine 200 is already filed in a U.S. Pending application with a Ser. No. 11/258,102, so here needs not redundant description.


The forming machine 100 has a main shaft 10 suspended by a V-shaped supporter 101 at center in the outer periphery thereof is an upper annular guide groove 11 and a lower annular guide groove 12. The upper annular groove 11 included a descending section 112 of long range of travel. The other portion is of horizontal. Whereas the lower annular groove includes a V-shaped quick descending section 122 of short range of travel. Both of the annular grooves 112 and 122 are provided to receive a plurality of rollers 111 and 121 to rotatably slide therein (as show in FIG. 8). The cutting machine 200 has also suspended from a V-shaped supporter 201 and each of the V-shaped supporters 101 and 201 are supported by a pair of columns and the bottom of the main shaft 10 is integrated with a circular base plate 14.


A revolving angler plate 13 on the top of the base plate 14 and revolved around the main shaft 10 is combined by a plurality of templates and has a plurality of outer concaves 131 for hooking the half-finished caps 1 and a plurality of inner concaves 132. The base plate 14 further has an arcuate wall 141 on an outer periphery and extends from the input disk 15 to the transferring disk 16 and forms a passageway with the rotating ring 13 therebetween for facilitating the half-finished caps 1 to safely go from the input disk 15 to the transferring disk 16. The cutting machine further has an output disk 21 on the opposite side of the transferring disk 16.


Both the disks 15, 16 and 21 has an inlet, an outlet and a double headed pusher 151, 161 and 211 rotatably pivoted to an axis 152,162 and 212 at center the of the disks 15, 16 and 21 with a bearing engaged therebetween. The double headed pushers 151, 161 and 211 each has a pair of inverse curves on opposite side and rotated clockwise to push in and out of the caps through the inlet and the outlet. Wherein the input disk further has a chips remover 17 inside a bottom and composed of a tube 171, a cutter 172 with a blade 1721 at upper end and an adjustable elastic stopper 175. The cutter is a cylinder with the blade 1721 embedded in a bottom of the desk 15 and the cutter 172 is hiding in a chips collection hole 174 of the tube 171 which further has a screw hole for engaging a threaded shank 173 to stop against the cutter 172 and to adjust the cutter to move up and downward. The input disk 15 has a cover 154 beneath the double headed pusher 151 for facilitate an elastic stopping member 175 of the cutter 172 to position on the top of the tube 171. The elastic stopping member 175 has a tubular cover 1751 inside which is a press plate 1752, an elastic plate 1754 biased by a spring 1753 and a nut 1755. The nut 1755 presses the press plate 1752 moving downward to force the spring 1753 and the elastic plate 1754 to jump up and downward to facilitate the half finished caps 1 passing through. Each of the caps 1 will be pressed by the elastic plate a little while to facilitate the blade 1721 of the cutter 172 to remove away the chips on the caps 1 (as shown in FIGS. 4, 5, 6 and 7).


Referring FIGS. 4, 8, 9 and 10, there is several cap forming device 18 positioned inside the circular base plate 14 and spacedly revolved around the main shaft 10. The devices 18 each has an upper pressing plate 181 and a lower pressing plate 182. The upper pressing plates 181 each has a roller (bearing) 111 on the back rotatably sliding in the upper guide groove 11, whereas the lower pressing plate 182 has also a roller (bearing) 121 on the back to rotatably slide in the lower guide groove 12. A pair of axial rods 183 spacedly and slidably penetrate through the rear side of the upper and lower pressing plates 181 and 182 and eventually positioned at a pair of the inner concaves 132 of the revolving annular plate 13 so that the cap forming device are revolving around the main shaft 10 by the revolving annular plate 13. A pressing axis 184 fixedly secures to a front under side of the upper pressing plate 181 and slidably passes through the lower pressing plate 182 so that the pressing axis 184 can move linking-up with the upper pressing plate 181. The axis 184 slidably links up a pressing block 185 and a U-shaped cover 186 at lower end. The U-shaped cover 186 covers the pressing block 185 and is biased on the top by a spring 187 which enable the U-shaped cover 186 to conduct vertical movement and a small gap defined between the pressing block 185 and the U-shaped cover 186.


A base box positions under the forming machine 100 and the cutting machine 200 and a motor (not shown) inside box and under the forming machine 100 and actuate the two machine 100 and 200 to operate together by the chains (not shown). The machines 100 and 200 each has a transparent protection cover 102 (as shown in FIG. 3). Each of the covers 102 has several transparent doors and each of the doors has a micro-switch. When the door is open, the switch is functioned to shut the machines 100 and 200 temporarily to avoid the danger.


Referring to FIGS. 4, 6 and 7, based on the aforediscussed structure, in operation, a conveyor (not shown) feeds the caps 1 into the input disk through the inlet. The double head pusher 151 pushes the cap 1 one by one about 90° relative to inlet, while the elastic plate 1754 of the stopping member presses downwind to temporarily hold the cap 1 waiting for the cutter 172 of the chips remover 17 to cut the chips away and the chips then drops into the chips collection hole 174 and the absorbing hole 153 of the input disk 15. Then use a hose of a vacuum cleaner (not shown) to suck the chips away from the chips collection hole 174 and the absorbing hole 153 in order avoid the chips to blocked these holes 174 and 153. The chips removed cap is continuously moved by the double headed pusher 151 for about 180° where the out concave 131 of the revolving annular plate 13 enables to accept cap 1 and brings the cap 1 to move forward along the inner side of the arcuate wall 141. This time, the pressing axis 184 is moving down by the downward movement of the upper pressing plate 181 and stops the against the center of the cap 1 to keep the cap 1 to be stable (accurate position without aslant). Immediately, the pressing block begins to press the reinforcement plates 4 and bends the reinforcement plates 4 downward. After the forming process, the cap 1 is released by the pressing axis 184 and moved to the inlet of the transferring disk 16 in which the double headed pusher 161 pushes the cap 1 about 180° to the outlet and simultaneously interred into the cutting machine for making the breaking-line thereon and after the cap 1 is completed, the finished caps 1′ are gathered to the inlet of the output disk and pushed out into a collection member (not shown). After repeated test, it proves that these machine 100 and 200 are very accurate and the operation is quick that it finishes several hundreds of the caps 1′ per one minute (as shown in FIGS. 11 to 14).



FIG. 5 shows an alternate arrangement of the chips remover 17. The change is that the stopping member 175 (as shown in FIG. 6) is removed and instead of is a cover plate 155 covering the tube 171. The cover plate 155 is capable of keeping cap 1 to be balancedly passing through and not to move upward. The chips remover can smoothly perform its chips removing action. Note that the specification relating to the above embodiment should be construed as an exemplary rather than as a limitative of the present invention, with many variations and modifications being readily attainable by a person of average skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
