Method and apparatus for packaging tape rolls

Apparatus for pre-stacking tape rolls and for packaging said tape rolls after pre-stacking wherein each tape roll has the same outside diameter and is wound around a central core of the same diameter comprising:

• a) magazine means having vertical side walls to surround and contain at least one stack of said tape rolls,
• b) said magazine being open at the top to permit the passage therethrough of said stack,
• c) means for conveying tape rolls into the bottom of said magazine to form one layer thereof, said magazine including bottom means to support said tape rolls therein,
• d) means to lift each said layer of tapes vertically from the bottom of said magazine one tape width high into said raised position,
• e) means forming a fixed horizontal supporting surface within said magazine and a second horizontally movable means forming another horizontal supporting surface, said second horizontally movable means including means to slide said tape upon said fixed horizontal surface, said respective supporting surface means being arranged beneath opposite sides of each said lifted tape to maintain and support said tape while a next said tape is moved by said conveying means there beneath,
• f) said conveyor means automatically injecting another tape roll into the magazine when the next preceding tape roll has been lifted to said raised position within said magazine,
• g) said horizontally movable means includes means for laterally moving said raised tape on said first surface and means for intermittent withdrawal from said magazine, and
• h) the apparatus of (c) (d) (e) (f) and (g) being operated to effect a stack of tapes consisting of a predetermined number of tapes.

A method for vertically stacking in a magazine a plurality of uniformly sized members having generally parallel flat upper and lower sides separated by a generally uniform width;

• said magazine having a flat bottom and extending therefrom vertical means to contain a stack of said members, said vertical means defining adjacent to the bottom of said magazine a side opening through which said members may be successively slid upon their lower sides into the magazine, the bottom of said magazine defining an opening through which a lifting element may raise successive ones of said members in said magazine to form a stack, said method comprising the steps of:
• a) conveying successive members flat side down into said magazine through said side opening therein,
• b) initially raising each said member from the bottom of said magazine at least one member width thereof,
• c) providing in said magazine at one side thereof opposite to the opening in the side of the magazine a stationary horizontal support located vertically above the bottom of said magazine at least one thickness of each said member,
• d) providing a second horizontal support which is reciprocally slidable into and out of said magazine through the side opening in said vertical means;
• said support having means to engage each said raised member to support and maintain said member in its initially raised position, means to engage each said raised member and to slide said member onto said stationary support,
• e) conveying a second member into said magazine beneath said first raised member while said first member is supported by said stationary and movable horizontal supports,
• f) withdrawing said horizontally movable support from said magazine while lifting said second member to support and raise said first member one member width in said magazine, and
• h) repeating steps (c) through (f) to create a stack of said members in said magazine.

• f) said conveyor means automatically injecting another member into the magazine when the next preceding member has been lifted to said raised position within said magazine,
• g) said horizontally movable means includes means for laterally moving said raised member on said first surface and means for intermittent withdrawal of said horizontally movable means from said magazine, and
• h) the apparatus of (c) (d) (e) (f) and (g) being operated to effect a stack of members consisting of a predetermined number of members.
