Abstract: The present invention is a cardboard sheet batch division device for dividing batches, disposed on the downstream side of a batch-forming device for separating loaded cardboard sheets and forming batches of a predetermined sheet count. The cardboard sheet batch division device for dividing batches comprises: a transfer conveyor for transferring batches formed by the batch-forming device in a predetermined transfer direction; and batch division means furnished with two separating members respectively contacting the leading edge portion and the trailing edge portion of a batch on the transfer conveyor, for dividing the batch into two sub-batches, upper and lower, by moving the two separating members relative to one another in a direction parallel to the predetermined transfer direction.

Abstract: A counter ejector of cardboard sheet box-making machine is disclosed. A front contact plate contacting cardboard sheets is movable in a feed direction. A spanker is disposed to face the front contact plate in the feed direction, and contacts the back edge portion of the cardboard sheet, aligning the sheet edge portions. Ledges separate cardboard sheets loaded between front contact plate and the spanker, forming a batch of a predetermined number of sheets. A transfer conveyor transfers batches in a transfer direction, which is the same direction as the feed direction. An elevator is furnished with a table, and carries batches from the height at which the front contact plate and the spanker are disposed to the height at which the transfer conveyor is disposed. The table is moved by the same amount and in the same movement direction as the movement of the front contact plate.

Abstract: A folder gluer for conveying a cardboard sheet and folding up the cardboard sheet from a deployed state thereof is disclosed. The folder gluer comprises two flat belts including a first belt and a second belt arranged in parallel for conveying a cardboard sheet, two pulleys provided at a starting part or a terminal part in a conveying direction of the folder gluer for respectively driving the first and second flat belts by friction forces, two motors for respectively driving the pulley for the first belt and the pulley for the second belt, a sensor device for respectively detecting the speeds of the first belt and the second belt, and a control device for controlling at least one of the two motors such that a difference in the speeds of the first belt and the second belt detected by the sensor device becomes zero.

Abstract: A counter ejector of cardboard sheet box-making machine is disclosed. A front contact plate 61 contacting cardboard sheets BS is movable in a feed direction FD. A spanker 62 is disposed to face the front contact plate in the feed direction, and contacts the back edge portion of the cardboard sheet, aligning the sheet edge portions. Ledges 63, 64A, and 64B separate cardboard sheets loaded between the front contact plate and the spanker, forming a batch BT of a predetermined number of sheets. A transfer conveyor 60 transfers batches in a transfer direction TD, which is the same direction as the feed direction. An elevator 65 is furnished with a table 65A, and carries batches from the height at which the front contact plate and the spanker are disposed to the height at which the transfer conveyor is disposed. The table is moved by the same amount and in the same movement direction as the movement of the front contact plate.

Abstract: An apparatus for accumulating and delivering folded cardboard sheets includes at least a pair of stacking bases moveable along a loop including a stacking position for stacking the cardboard sheets on the stacking bases and a delivering position for delivering the pile of cardboard sheets on the stacking bases. The apparatus receives cardboard sheets fed one by one, accumulates them in a pile consisting of a predetermined number of cardboard sheets, and delivers the pile of sheets. When one of the stacking bases moves away from the stacking position, the other is moved into the stacking position so that the stacking bases alternatively move into the stacking position. Preferably, the loop has resting and ejecting positions and when one of the stacking bases moves from the ejecting to the stacking position, that stacking base ejects the pile of sheets previously formed on the other stacking base.

Abstract: The present invention relates to an apparatus for accumulating and delivering folded cardboard sheets which can be reduced in cost and improved in reliability thereof sue to a simplified construction of the apparatus and facilitated control of the movement of the ledge.

Abstract: The present invention relates to an apparatus for accumulating and delivering folded cardboard sheets which can provide a high production efficiency. The apparatus comprises at least a pair of stacking bases 24 and 26 being moveable along a loop, the loop including in its path a stacking position for stacking the cardboard sheets on the stacking bases and a delivering position for delivering the pile of the cardboard sheets formed on the stacking bases. The apparatus receives cardboard sheets 6 being fed one by one, accumulates them in the form of a pile consisting of a predetermined number of the cardboard sheets, and delivers the pile of the cardboard sheets. Wherein when one of the stacking bases 24 is moved away from the stacking position, the other one of the stacking bases 26 is moved into the stacking position in such a manner that the pair of stacking bases 24 and 26 are alternatively moved into the stacking position.
