Move to position. The second limit switch 108 also controls the contraction of the piston portion 100 of the assembly 96, which causes the kicker plate 94 to move to its vertical position when the carrier edge plate moves to its second position. The second limit switch 108 further controls the contraction of the piston portion 40 of the assembly 36, which returns the carrier edge plate 30 to its first position. A detent member 110 is attached to the frame structure 18 to contact and actuate the switch 108 during movement of the carrier edge plate to the second position. The longitudinally extending portion of detent member 110 maintains the switch in its actuated position for a short period of time during which the actuation just described is initiated. When the carriage edge member 30 begins to return to its first position, the limit switch moves away from the detent member 110 and returns to the inoperative position where it reopens the vacuum source to the suction cup member 84.

A third limit switch 112, which controls the extension of the piston portion 68 of the assembly 64, is properly positioned on the carrier edge plate 30 to fold the carrier edge plate 30 back to its first position. Move arm assembly 44 to its first position. A detent member is attached to the frame structure 18 to contact and actuate the switch 112 while the switch 112 is moving to its first position on the carry edge plate 30.

A fourth limit switch 116, which controls the contraction of the piston portion 68 and the extension of the piston portion 78, is appropriately positioned on the carrier edge plate 30, which causes the folding arm assembly 44 to be in its first position. When reached, the folding arm assembly 44 and the pivot arm assembly 46 respectively begin to return to their second positions. When the folding arm assembly 44 reaches its first position, it activates the plate 56 as it contacts the switch 116.

The operating cycle of the assembly apparatus 10 will be described by passing the cardboard box 22 through the apparatus. To prepare the apparatus for operation, the magazine assembly 20 is filled with a plurality of prefabricated carton stocks, all of which are vertically oriented and inserted into the magazine in the same orientation. The carton blanks are aligned such that their side panels have an edge fold to the left as shown in FIG. During assembly of the device, the members 24, 26 of the magazine assembly 20 are attached to the full width of the prefabricated carton blank in a known manner. The member 24 of the magazine assembly 20 is appropriately adjusted to direct the carton material to the carton assembly section 14 so that the fold line at the bottom of the carton (when folding the bottom flap, Is at the same height as the kicker plate 94 when the kicker plate 94 is in its horizontal position. The guide rails 105 are adjusted appropriately to accommodate the dimensions of the particular carton loaded in the magazine assembly 20. The folding arm 48 is adjusted with respect to the support member 54 to align the plow member 102 with the longitudinal centerline of the assembly carton.

That is, the carry edge plate 30, folding arm assembly 44, and pivot arm assembly 46 are in their first positions, and the kicker plate 94 is in its vertical position. The plate 56 is in contact with the switch 116, and the detent member 114 is in contact with the switch 112.

When the device 10 is so positioned and the device is in the “on” position, a vacuum source is provided to the suction cup member 84, which causes the suction cup 90 to move the balls in front of the magazine assembly cube 20. Hold the side panel of the box material. At the same time, the folding arm assembly 44 and the pivot arm assembly 46 are moved to their second positions by the respective cylinder assemblies 64, 74 in the manner described above, as shown by the solid lines in FIG. Let When the folding arm assembly 44 and the pivot arm assembly are moved to their second position, the preceding carton material is moved by the inward movement of the suction cup 90 which is in contact with the side panel of the carton. It is pulled inward from the magazine assembly 20 into the carton assembly section 14. The pivoting of the folding arms 48 brings the surface 50 into contact with the trailing end panel of the carton and when the folding arm assembly 44 and the pivot arm assembly reach their second positions at the same time, the carton material is tubularly assembled. Open to form.

When the folding arm assembly 44 reaches its second position, the pin 107 contacts and actuates the switch 106, while at the same time actuating the cylinder assembly 96 to move the kicker plate 94 to the tray. Move the ring bottom flap to a horizontal position to fold in and activate the cylinder assembly 36 to initiate movement of the carriage edge assembly 30 toward its second position, as shown in phantom in FIG. The assembled carton is transported to the bottom flap folding section 16 in the manner described above.

When the carriage edge plate 30 reaches the second position for transporting the assembled carton to the bottom flap folding section 16, the detent member 110 contacts the switch 108 which controls the start of a series of operations.

Cylinder assembly 74 initiates movement of pivot arm assembly 46 back to the first position. Cylinder assembly 96 initiates movement of kicker plate assembly 92 to return kicker plate 94 to its vertical position. Cylinder assembly 36 initiates movement of carrier edge plate 30 to return carrier edge plate 30 to its first position.

The assembled carton in the bottom flap folding section 16 is conveyed by a suitable conveyor (not shown) to move the assembled carton through the section 16. As the assembly carton moves through section 16, plow 102 contacts and folds the leading bottom flap, and side plow member 104 contacts and folds the bottom flap. Therefore, the ball box exiting the carton box assembly machine is assembled and all bottom flaps are folded.

When the carry edge plate 30 leaves the carton box assembly section 16, the switch 108 is released from contact with the detent member 110 and returns to its initial position, thus returning the vacuum supply to the suction cup member 84. When the carriage edge plate 30 returns to the first position within the carton box assembly section 14, the detent member 114 contacts and actuates the switch 112 and the cylinder assembly 64 causes the folding arm assembly to move to its first position. Rotate to the position. The components of the carton assembly are now in their initial position in preparation for gripping the next carton blank and repeating the operating cycle.

Thus, a new ball box assembling apparatus for easily assembling the assembly box material has been described. Although the present invention has been described in necessary detail, this disclosure is considered to be exemplary and the invention is intended to include structural details and various changes in assembly and arrangement of parts within the scope of a utility model registration request.
