Description

  The present invention is used in a printing factory that prints newspapers and magazines, a factory that manufactures and processes various items, and is installed in a conveyance line that conveys articles such as newspapers, magazines, and products to a predetermined position. The present invention mainly relates to a sorting apparatus that sorts a transported article (packaging article) such as a newspaper or magazine packed and bound in a printing factory such as a newspaper.

  In general, in a newspaper shipping line in a newspaper printing factory, newspapers discharged from a printing press folding machine are transported to a counter stacker by a carrier device and stacked in a certain number of bundles to form a newspaper stack. After that, the newspaper stack is transported to a packaging machine and binding machine (or packaging binding machine) by a conveyor or other transporting device, packed and bound here, and then sent to a loading place where the truck is waiting. The newspaper stack packed and bound by the sorting device is sorted according to the destination.

By the way, the newspaper stack is usually wrapped in a transparent resin film, and its periphery is bound by a resin band. For this reason, roller conveyors are not suitable for the wrapped and bundled newspaper stack transfer device, and belt conveyors are mainly used.
Also, as the sorting device, a pusher type or a partition plate type is avoided because the resin film is easily damaged, and a swivel type is widely used.

  2. Description of the Related Art Conventionally, as a sorter of this type, one having a structure in which a sorter belt conveyor is pivotably arranged between an upstream belt conveyor and a downstream belt conveyor arranged in a straight line is known (for example, Patent Document 1, Patent Document 2, and Patent Document 3).

  That is, although the sorting device is not shown, the sorting belt conveyor is rotated in the forward and reverse directions by a swivel base and a rotating shaft in a space formed between the end portion of the upstream belt conveyor and the start end portion of the downstream belt conveyor. The sorting belt conveyor is swiveled at a predetermined angle in the forward / reverse direction by a driving device composed of a fluid pressure cylinder, a motor, etc., and the sorting belt conveyor is moved downstream by the driving device. When it is directed to the belt conveyor, the sorting belt conveyor receives the transported material sent from the end of the upstream belt conveyor and sends it to the downstream belt conveyor, and the driving device transfers the sorting belt conveyor to the belt conveyor. If the sorting belt conveyor is oriented at an angle to the direction, the end of the upstream belt conveyor Receive fed out conveyed sending it to the oblique direction, in which as sorting and discharged to the discharge chute arranged the conveyance object in lateral position of the sorting belt conveyors.

By the way, in the sorting apparatus, there is a problem that when sorting the conveyed items, the conveyed items protrude from the sorting belt conveyor due to centrifugal force as the sorting belt conveyor turns. Therefore, in the sorting apparatus disclosed in Patent Document 1 and Patent Document 2, a side plate is erected on the side surface of the conveyor frame of the sorting belt conveyor to prevent the conveyed product from protruding. When the transported object collides strongly, another problem occurs that the transported object is damaged. In particular, these problems become more prominent when transported materials are conveyed and sorted at high speed.
Further, in the sorting devices disclosed in Patent Document 1 and Patent Document 3, since the fluid pressure cylinder is used as the driving device, it is difficult to rotate the sorting belt conveyor at high speed, and it is not suitable for high-speed sorting of conveyed objects. Therefore, there is a problem that it is difficult to improve the sorting ability.

The inclined angle is an ascending inclined surface of θ4 (see FIG. 1). As a result, even when the newspaper stack S is being transported at a high speed when sorting the newspaper stack S, the sorting belt conveyor 7 has an inclined surface with the outer side being higher and the inner side being lower. Thus, the newspaper stack S that has been transferred to is not ejected from the sorting belt conveyor 7 by centrifugal force, and the newspaper stack S can be quickly discharged in a stable state.
Further, since the direct drive motor 17 or the like is used for the drive device 8 for turning the sorting belt conveyor 7, the turning of the sorting belt conveyor 7 can be performed in a short time and the newspaper stack S can be sorted at high speed. The improvement can be achieved and the noise when the sorting belt conveyor 7 turns can be reduced.

  Then, when the sorting belt conveyor 7 discharges the newspaper stack S to the sorting chute 24, the driving device 8 turns 45 degrees from the discharging position to the conveying position, and the newspaper stack S that is continuously sent to the belt conveyor 2 on the downstream side.
