Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport box-shaped object collecting apparatus.

[0002]

2. Description of the Related Art For example, as an apparatus for accumulating a transport box-shaped object, as shown in the side view of FIG. 3, a stopper for transporting a box-shaped object 01 from a front side to a rear side of a supply conveyor 02 has been used as an object stopper. 03 and a grip conveyor 04 consisting of a pair of upper and lower parts, and an object separating device 05, and a front tension sprocket 06 arranged downstream thereof.
And a standing stacking conveyor 010 in which a plurality of transport lugs 09 are arranged in a row on an endless chain 08 wound around a rear driving sprocket 07, and a standing stacking conveyor drive device 012 for rotating the driving chain 011 of the driving sprocket 07.
And a dispensing mechanism 013 and the like arranged on the upper side of the upright stacking conveyor 010 are known. In such a device, the box-shaped objects 01 that are continuously supplied from the upstream from the supply conveyor 02 are sequentially divided into one piece by the object stopper 03 being raised and lowered intermittently, and the box-shaped objects are divided. Object 01 is grip conveyor 04
In the state where the upper and lower sides are sandwiched by, the sheets are sequentially received on the transport lugs 09 which are serially arranged in the downstream thereof. Subsequently, the endless chain 08 is moved by one pitch of each transport lug 09,
The above operation is repeated each time. In this way, when a predetermined number of box-shaped objects 01 are erected and accumulated on the endless chain 08, the payout device 013 pays them out laterally to the cradle 12 shown in FIG.

However, such a device has the following drawbacks. (1) Since the interval between the transport lugs 09 on the endless chain 08 is constant, only the box-shaped object 01 having a constant size can be handled, and therefore it is practically inconvenient. (2) Therefore, if the intervals between the transport lugs 09 are relatively wide so that the box-shaped objects 01 having a plurality of sizes can be handled, the relatively small box-shaped objects 01 are dispensed from the transport lugs 09 by the dispensing device 013. There is too much room to put it out, so a box-shaped object 0
The posture of No. 1 collapses, and as a result, the labor for posture correction is required, and thus automation of the device is difficult.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of such circumstances, and it is possible to stably handle box-shaped objects having a plurality of types of outer shapes by performing a selection operation. Therefore, it is an object of the present invention to provide a carrier box-shaped object accumulating device excellent in practicability and automation.

[0005]

SUMMARY OF THE INVENTION To this end, the present invention is directed to a plurality of cascading conveyor lugs arranged downstream of a box-shaped object feeding conveyor and a box-shaped object separating device and capable of loosely gripping a box-shaped object on a belt conveyor. In the stacking device for the arranged transport box-shaped objects, the transport lugs are arranged in a group on the belt conveyor, and a plurality of transport lug groups having different transport lug pitches are provided for each group. And a rising and stacking conveyor driving device capable of freely selecting the conveying distance of the belt conveyor according to the pitch of each conveying lug of each conveying lug group.

[0006]

According to this structure, a plurality of conveying lugs arranged downstream of the box-shaped object supply conveyor and the box-shaped object separating device and on which a box-shaped object can be loosely inserted are arranged in cascade on the belt conveyor. In a box-shaped object accumulating device, a plurality of transport lug groups are provided in which the transport lugs are arranged in a group on the belt conveyor, and the pitch of the transport lugs is different for each group, and each of the transports. Since the upright stacking conveyor drive device is provided which can freely select the transporting distance of the belt conveyor according to the pitch of each transporting lug of the rug group, the following operation is performed. (1) By selecting the internal pitches of a plurality of transport lug groups on the belt conveyor, it becomes possible to handle box-shaped objects of multiple types of external shapes. (2) By selecting the internal pitch of multiple transport lug groups on the belt conveyor, the gap between the unit lug and each box-shaped object does not become too large, and as a result, the box-shaped during the dispensing process is performed. The stability of the object is increased.
