Abstract
Abstract A case set-up and bottom sealing machine, including a programmable controller that controls: (a) the movement of cases from a hopper to a case set-up station and, then, to a mandrel station; (b) the erecting of cases at the case set-up station; (c) the tucking or folding of the bottom minor and major flaps of erected cases at the case set-up station; (d) the application of glue to the bottom flaps during movement from the case set-up station to the mandrel station; and (e) the application of pressure to the bottom flaps to adhere the flaps together at the mandrel station, is disclosed. If the case includes Tab-Lok top flaps, the case set-up and bottom sealing machine can be programmed to fold the Tab-Lok flaps into a position such that the Tab-Lok flaps overlap the sides of the case when the case is erected. The programmable controller controls the operation of the case set-up and bottom sealing machine in accordance with operator inserted instructions, which includes case length, glue pattern length and compression time instructions, plus on/off instructions regarding glue application and glue format (stitch or continuous). The readily changeable operator inserted instructions are entered via a control/display unit, which displays information about the function and changes being made when the instructions are being entered and case count information when the case set-up and bottom sealing machine is running.
