Abstract

Various embodiments of the present disclosure provide a case former configured to receive a case in a blank configuration, open the case into a tubular configuration, fold the lower minor flaps to manipulate the case into a partially closed-bottom configuration, square the case while in the partially dosed-bottom configuration, and fold and tape the lower major flaps shut to manipulate the case into a closed-bottom configuration. The squaring step ensures that the case has a rectangular cross-section after taping rather than a rhomboid cross-section.

First claim

The invention claimed is:

1. A case former comprising:
a case-moving assembly comprising a case mover and a case-moving-assembly actuator operably connected to the case mover to move the case mover from a rest position to a delivery position;
a case squarer comprising a squaring component and a case-squarer actuator operably connected to the squaring component to move the squaring component from a squaring position to a case-passage position;
a second case-moving assembly, wherein the squaring component is positioned to at least partially block an entrance to the second case-moving assembly when in the squaring position and not to block the entrance to the second case-moving assembly when in the case-passage position; and
a controller operably connected to the case-moving-assembly actuator and the case-squarer actuator, the controller configured to, after a case has been received by the case mover, control the case-moving-assembly actuator to move the case mover from the rest position toward the delivery position so the case contacts a part of the case squarer.

2. The case former of claim 1 , wherein movement of the case mover from the rest position to the delivery position causes contact between the case and the squaring component of the case squarer to manipulate the case into having a rectangular cross-section.

3. The case former of claim 2 , wherein the case comprises four walls, wherein the case has the rectangular cross-section when the interior angles formed between adjacent walls of the case are within two degrees of ninety degrees.

4. The case former of claim 1 , wherein the case-squarer actuator is configured to rotate the squaring component from the squaring position to the case-passage position.

5. The case former of claim 1 , further comprising a sensor, whereinthe controller is communicatively connected to the sensor and further configured to, responsive to the sensor being triggered, control the case-squarer actuator to move the squaring component from the squaring position to the case-passage position.

6. The case former of claim 5 , whereinmovement of the case to a designated position triggers the sensor.

7. The case former of claim 6 , whereinthe sensor is triggered upon the sensor detecting the case.

8. The case former of claim 6 , whereinthe sensor is triggered upon the sensor detecting something other than the case.

9. The case former of claim 6 , wherein the sensor is positioned downstream of the part of the case squarer.

10. A case former comprising:
a first case-moving assembly comprising a case mover and a case-moving-assembly actuator operably connected to the case mover to move the case mover from a rest position to a delivery position;
a case squarer comprising a squaring component and a case-squarer actuator operably connected to the squaring component to move the squaring component from a squaring position to a case-passage position;
a second case-moving assembly comprising opposing side drives and a side drive actuator operably connected to the side drives to drive the side drives, wherein the squaring component is positioned to at least partially block an entrance to the second case-moving assembly when in the squaring position and not to block the entrance to the second case-moving assembly when inthe case-passage position; and
a controller operably connected to the case-moving-assembly actuator and the case-squarer actuator, the controller configured to, after the case has been received by the case mover, control the case-moving-assembly actuator to move the case mover from the rest position toward the delivery position so the case contacts a part of the case squarer.
