Abstract:
1. A cardboard sheet batch division device, disposed on the downstream side of a batch-forming device, for separating loaded cardboard sheets which are folded and glued and forming batches of a predetermined number of cardboard sheets, said cardboard sheet batch division device comprising; a transfer conveyor for transferring batches of a predetermined number of cardboard sheets loaded by the batch-forming device in a predetermined transfer direction; and batch division means comprising a leading separating member and a trailing separating member for dividing the batch into two sub-batches, upper and lower, by moving the leading separating member and the trailing separating member relative to one another, the leading separating member disposed to contact the leading edge portion of the batch on the transfer conveyor to adjust the amount of protrusion thereof from one surface among the top and bottom surfaces of the batch toward the other surface thereof and the trailing separating member disposed to contact the trailing edge portion of the batch on the transfer conveyor whose leading edge portion is not contacting the leading separating member, so as to adjust the amount of protrusion thereof from the other surface among the top and bottom surfaces of the batch toward the one surface thereof; a trailing adjustment device for moving the trailing separating member in the up/down direction to adjust the amount of protrusion by the trailing separating member; a separating member drive device for moving the leading separating member and the trailing separating member relative to one another in a direction parallel to the predetermined transport direction; a support member disposed to advance into the batch transfer pathway of the transfer conveyor in order to support the bottom surface of the sub-batch cardboard sheet positioned on top from among a first sub-batch of cardboard sheets whose leading edge portion is contacting the leading separating member, and a second sub-batch of cardboard sheets whose trailing edge portion is contacting the trailing separating member; a support member adjustment device for moving the support member relative to the transfer conveyor to cause the support member to advance into the transfer pathway, or to cause the support member to withdraw from the transfer pathway; and a control device for respectively controlling the trailing adjustment device, the separating member drive device, and the support member adjustment device to push at least one of the sub-batches among the first sub-batch and the second sub-batch in a direction parallel to the predetermined transport direction so that the batch is divided into the first sub-batch and the second sub-batch; wherein in at least one of the leading separating member and trailing separating member moves in a direction parallel to the predetermined transfer direction and wherein each of the leading separating member and trailing separating member is respectively disposed to adjust an amount of protrusion thereof in an up/down direction relative to the batch on the transfer conveyor.
