DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a paper box using corrugated paper or the like with a box making machine and then stacking the paper boxes to bind the paper boxes.

[0002]

A box making machine sends out a completed paper box in a flat crushed shape. Usually, the paper box is completed in this state, and a number of the flat paper boxes, for example, ten, are stacked and bound to be handled. In the flat paper box, in a so-called bottom-attached box or the like, 4 to 5 sheets of paper overlap at the bottom portion, and 1 to 4 at the lid portion.
The two sheets are overlapped, and the cross section has a substantially triangular shape and a non-uniform thickness. For this reason, if a large number of paper boxes are stacked as they are, the paper boxes are likely to collapse. Therefore, usually, half of the paper boxes are stacked in the opposite direction so that the entire thickness becomes uniform.

[0003] To perform such lamination, a dedicated automatic machine is known, but has the following complaints. Since this machine is directly connected to a box making machine, individual paper boxes cannot be inspected manually, and defective products may be mixed in the laminate. In addition, specially shaped boxes cannot be processed by this machine and must be handled manually.Therefore, a device to temporarily evacuate this machine or a transport device to bypass this machine is required. Becomes Therefore, in addition to the machine itself, space for the device is essential, requiring a large amount of space.

Therefore, the present invention is not to automate the laminating work, but to make the work more efficient while leaving the manual work, so that inspection and specially shaped boxes can be handled easily and in a small space. .

[0005]

In the apparatus for stacking paper boxes according to the present invention, a stacking pit having a guide plate is provided at the tip of a delivery conveyor of a box making machine, and an operator inspects a completed paper box from the delivery conveyor. At the same time, the paper box is dropped as it is, or the top and bottom of the paper box are inverted, and the top and bottom of the paper box are guided on a guide plate to be stacked. The stacked paper boxes are conveyed laterally by a horizontal conveying device below the guide plate and sent to the next step.

In this apparatus, since the layers are manually stacked, visual inspection becomes possible, and it is possible to deal with paper boxes of various shapes. Since the stacking operation is performed by dropping the paper box, the physical burden on the worker is reduced. When stacking specially shaped paper boxes,
By removing only the laminated pit portion, or passing a roller box over the laminated pit and transporting the paper box, a work space can be easily provided, and separate manual lamination without using this device at all Becomes possible.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has a guide plate which can adjust the distance and guides the top and bottom of a paper box, and is connected to a delivery conveyor for delivering a completed paper box of a box making machine. A worker located at the end of the delivery conveyor inspects the paper box, and a stacking pit is provided below the stacking pit for stacking the paper box by dropping it as it is or by turning it upside down,
This is a paper box laminating operation device comprising a horizontal transport device that transports a paper box in a lateral direction with respect to the conveyor after laminating a predetermined number of paper boxes.

[0008] The horizontal transport device can be of any configuration as long as it transports the paper box in the horizontal direction, and a belt conveyor or the like can be used. Also, using a roller conveyor,
A device that transports the stacked paper boxes by manual operation of an operator, a motor that drives some or all of the rollers in the roller conveyor, or an actuator that presses the stacked paper boxes can also be used.

When a roller conveyor is used, it is desirable that the roller at the center of each roller be shorter than the others and be held by both guide plates alternately in a cantilever manner. In this case,
When the two guide plates are brought close to each other in accordance with a small paper box, the worker can be located at a position close to the guide plates, which facilitates the work.

[0010] Further, it is desirable to provide an ascending and feeding device connected to the horizontal transport device, which raises the paper box and sends it out to the binding device. In this case, when the ascending transport device is provided, the paper box once dropped at the time of lamination is raised and sent out to the binding device, so that the binding device is installed at a normal height, and the subsequent handling of the bound paper box is also normal. .

The ascending delivery device can have any configuration as long as it raises and transports the paper box. For example, those having a chain conveyor for vertically raising the paper box from the horizontal transport device with both ends placed, or those having a belt conveyor that extends diagonally and raises the paper box from the horizontal transport device while transporting it. Can be used.

[0012] To the binding device, a band-type binding machine that conveys and binds in the same direction as the paper box transport direction of the ascending delivery device, or transports the transport device in a direction perpendicular to the paper box transport direction of the ascending delivery device, A string type binding machine for binding can be used.
