This relates to a capper for applying closures to containers. In a packer's plant there is frequently a necessity to modify a capper so as to apply closures to containers of different diameters and different heights with the closures also being different in diameters, thicknesses, etc. In the past, the cappers have been provided with change parts and are in a certain degree adjustable so that a capper can be modified to accept a range of container diameters and heights and closure sizes. However, shut-down time has continued to be an important factor. Further, final adjustment of the capper after modification has been a problem. There has been provided a universal capper which is provided with height and width adjustments for both containers and closures and all of these adjustments may be made while the machine is operating so as to obtain minute adjustments. The changeover time is no longer a factor with the universal capper. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
A universal capper for applying caps to containers, said capper comprising a base, an endless conveyor carried by said base and having a container supporting run at a fixed elevation, a first support, first mounting means mounting said first support for vertical adjustment relative to said base, container retaining belt means carried by said first support on opposite sides of a longitudinal center line of container passage through said machine, a capper head, second mounting means mounting said capper head for vertical movement relative to said base, a second support, mounting means mounting said second support on said capper head for vertical adjustment both with and with respect to said capper head, closure rotating belts carried by said second support on opposite sides of said center line, a third support carried by said capper head for vertical adjustment therewith relative to said base, closure guide chute elements carried by said third support on opposite sides of said center line, and adjusting means for separately adjusting the spacing of said container retaining belts, said closure guide chute elements and pressure areas of said closure rotating belts and for separately vertically adjusting the height of said first, second and third supports and said capper head while said capper is operating, said first mounting means including four rectangularly arranged column type supports between said base and said first support, a threaded shaft and nut arrangement within each column type support between said base and said first support, and drive means connected to said threaded shaft and nut arrangement for actuating the same in unison to vertically adjust the elevation of said first support and thus said container retaining belts while said capper is in operation, each of said container retaining belts having a drive including a rotatable drive element fixed relative to said first support for rotation, said container retaining belts having opposed runs for engaging containers, and adjustable belt positioning shoes engaging said container retaining belts and determining the transverse positions of said opposed runs to accommodate containers of different diameters.
