Abstract

To provide a plate material conveying system configured to load plate materials produced by a press work onto a tray at regular intervals, prior to a cleaning process. The plate material conveying system comprises: a feeding section 13 that feeds the plate materials produced by the press work at regular intervals; a storage section 14 that stores the plate materials conveyed sequentially from the feeding section 13; a loading section 15 that loads the plate materials stored in the storage section 14 on the tray opposing thereto at one time; and a discharging section 16 that conveys the tray from a site to be opposed to the storage section 14 to a predetermined site.

First claim

The invention claimed is:

1. A plate material conveying system, in which a plurality of plate materials conveyed from a pressing section are aligned in array in the same orientation at regular intervals to be loaded into a tray, and in which the plate materials loaded into the tray are conveyed by conveying the tray,
characterized by comprising:
a feeding section that feeds the plate materials from the array of the plate materials contacted to one another on a predetermined flat site one by one at regular intervals;
a storage section that has a plurality of shelves into which the plate materials conveyed sequentially from the feeding section are inserted, and that lifts one step in a direction perpendicular to a conveying direction of the feeding section to align an empty space of the shelf to the following plate material each time the plate material is inserted into the shelf;
wherein the tray comprises a plurality of support members into which side edges of the plate materials are inserted at same intervals as the plate materials stored in the shelf of the storage section;
a loading section that loads the plate materials stored in the storage section on the tray at one time by opposing the tray to the storage section in which a predetermined number of the plate materials are stored, and by moving the storage section toward the tray; and
a discharging section that conveys the tray on which the plate materials are loaded from a site to be opposed to the storage section to a predetermined site.

2. The plate material conveying system as claimed in claim 1 , further comprising a tray conveying section including:
a feeding hopper in which the empty trays are stacked;
a conveyor belt that conveys the tray discharged from the feeding hopper to the storage section; and
an erecting device that erects the tray to oppose the tray to the storage section.

3. The plate material conveying system as claimed in claim 2 , wherein the loading section comprises a pushing mechanism that pushes the plate materials loaded on the shelf of the storage section toward the tray opposed to the storage section at one time from an opposite side to the tray.

4. The plate material conveying system as claimed in claim 1 , wherein the storage section is configured to store the plate material by supporting the side edges of the plate material conveyed from the feeding section to the shelf, and lifting the shelf upwardly one step.

5. The plate material conveying system as claimed in claim 1 ,
wherein the tray comprises a plurality of shelves to store the plate materials,
same number of the feeding sections and the storage sections as the shelves of the tray are arranged,
the feeding section comprises a loading device that loads predetermined number of the plate materials conveyed from the pressing section onto the storage sections alternately, and
the discharging section comprises a sliding mechanism that moves the tray in which the plate materials are loaded into one of the shelves from one of the storage sections to a site to be opposed to the other one of the storage sections.

6. The plate material conveying system as claimed in claim 1 ,
wherein the support member of the tray includes a rack bar having a groove into which the side edge of the plate material is inserted,
the tray comprises an opening formed on an opposite side to the storage section at a site corresponding to a longitudinally intermediate portion of the plate materials in which both side edges are inserted into the grooves, and
one end of the groove opposed to the storage section is open, and the other end of the groove opposite to the storage section is closed.
