Abstract

PURPOSE:To prevent the breakage defect due to the contact by collecting the plate- shaped articles supplied to a collecting position at a high speed by installing a shock softening means installed at a front position in the plate-shaped article feeding direction in a collection part and an upper and horizontal air stream discharge means installed at a rear position. CONSTITUTION:When a plate-shaped article 8 is supplied into a collecting part 15, an upper air stream 4 is discharged from a front guide 2, and further a horizontal air stream 5 is discharged from a horizontal air stream blow-out means 3. Therefore, the front edge 8a of the plate-shaped article is supplied into the collecting part 15 free from the contact with a piled bundle 9, and the front edge collides with a shock softening means 7. Further, a horizontal air stream is discharged from the horizontal air stream discharge means 3 onto the plate-shaped article 8 which drops onto the collecting part 15, having an air layer as cushion layer, and the cushion air between the plate-shaped article 8 and the collected bundle 9 is expelled from under the plate- shaped article 8, and the plate-shaped article 8 is speedily collected onto the collected bundle 9. Thus, the plate-shaped article 8 is prevented from being broken by contact, and since the cushion air is expelled at the same time, the high speed piling can be realized.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to an apparatus for accumulating plate-like objects on a stacking position, and more specifically, a device for accumulating plate-like objects on a stacking position, and more particularly, a device for stacking plate-like objects on a stacking position. This invention relates to a contactless accumulation device that can supply and accumulate objects.

(Prior art) For example, in the manufacturing process of plate-like products such as aluminum webs (thin plates), a plurality of plate-like products are fed from a supply means such as a belt conveyor for subsequent processes such as taking out and packaging. It is widely practiced to stack and accumulate them in a row.

The above-mentioned accumulation of plate-like objects is usually carried out by feeding the plate-like objects one by one in a substantially horizontal direction from near the accumulation position toward the top of the accumulation position, and aligning the accumulation positions with a guide plate while stacking the plate-like objects. This is done by dropping it into a predetermined collection location. However, in this stacking method, there is a problem that the bottom surface of the newly supplied plate rubs against the top of the plate that has already been stacked at the stacking position, causing scratches on the plate. was.

In order to eliminate the above-mentioned problems, it has been conventionally done to insert interleaf paper between the plate-like objects to accumulate them. In particular, this work of removing the interleaf paper is difficult to automate, making it extremely troublesome.

Therefore, there is a method in which the supplied plate-like objects are floated by discharged air and dropped onto the stacking plate-like objects via an air suction to be accumulated.

(Problem to be Solved by the Invention) A device for accumulating such plate-shaped objects is disclosed in Japanese Patent Application Laid-Open No. 58427.
As shown in Publication No. 98, blowing an upward air flow over the entire width of the lower surface of the plate-shaped object being fed causes the plate-shaped object to float.
A common method is to drop the plate to the stacking position without letting it fall. In this method, the front end (
There was an inconvenience that the front end) would come into contact with the accumulated plate-like objects and cause scratches. Also, JP-A-57-1158
In the vacuum accumulation method using a Zakujo conveyor and the method of temporarily holding plate-like objects using an impeller method and then accumulating them at the accumulation position shown in Japanese Patent Application Laid-Open No. 56-93653, the accumulation speed is increased. There were some inconveniences, such as poor efficiency and poor performance.

In view of the above-mentioned problems, the present invention is capable of accumulating plate-shaped objects supplied to an accumulation position at high speed, and can prevent scratches, scratches, etc. due to contact with the accumulated plate-shaped objects. The purpose of this invention is to provide a non-contact accumulation device for plate-like objects.

(Means for Solving the Problems) The present invention provides a plate-like object stacking device that supplies plate-like objects from the vicinity of a stacking section toward the top of the stacking section in a substantially horizontal direction and drops them to accumulate them in the stacking section. a buffer provided at a forward position of the stacking unit in the plate-shaped article supply direction, the buffer blocking the front end of the plate-shaped articles supplied to the stacking unit and regulating the stacking front end position of the plate-shaped articles; means, and a two-way airflow discharge means provided at a position on the rear side of the stacking section in the direction in which the plate-like objects are supplied, the device discharging an upward airflow toward the entire width of the lower surface of the plate-like objects supplied to the stacking section. , a horizontal air flow provided at a position on the rear side of the stacking unit in the supplying direction of the plate-shaped articles, which discharges a horizontal airflow toward both front end and both ends (=1) of the plate-shaped articles supplied to the stacking unit; It is characterized by comprising a discharge means.

(Function) Since the present invention has the above-mentioned structure, the plate-shaped objects supplied to the accumulation section are floated by the air flow S4 discharged by the upward air flow discharge means, and at the same time are discharged from the horizontal air flow discharge means. The airflow causes both ends of the front end of the plate-like object to float. Therefore, the front end of the plate-like objects, which are particularly likely to descend and come into contact with each other, can be dropped into the stacking section via the cushion air and stacked without coming into contact with the stacked plate-like objects.

(Example) An example of the present invention will be described below with reference to the drawings. 1st
The figure is a side explanatory view of an embodiment of the non-contact accumulation device for plate-like objects of the present invention, and FIG. 2 is a perspective view. As shown in FIG. It is an integrated device with a structure that can be supplied.

This stacking device is a stack partitioned by a front guide 2, a buffer means 7 provided opposite to the front guide 2, and side guides 6 arranged to connect the left and right sides of the guide 2 and the buffer means 7. The section 15 has a belt conveyor 1- for conveying the plate-like object 8. This bell! - A plate-shaped object 8 such as an aluminum web (thin plate) is conveyed on the conveyor 1 in a substantially horizontal direction (arrow A), and this plate-shaped object 8 is separated from the belt conveyor 1 and placed above the accumulation section] 5. It advances in a substantially horizontal direction, and falls onto the stacked plate-shaped objects (collected bundle) 9, with its front end 8a abutting against the buffer means 7 and the front end position being defined. At this time, the left side position and right side position of the plate-like object 8 are defined by the side guide 6, and at the same time, the rear end position is defined by the front guide 2, and a large number of plates are gathered in the stacking section 15 into one stacked bundle 9.
It is accumulated as follows.

At the top of the front guide 2, there is a "two-way air flow discharge 1" means 16 consisting of a plurality of holes that discharge the air flow 4 upward.
Or is provided. This upper airflow discharge means 6 is opened in a shape that allows airflow to be blown over the entire width of the lower surface of the plate-shaped object 80 passing above the front nozzle 1 id 2 .

Further, a horizontal air flow discharge means 3 for discharging air flow 5 in the horizontal direction is provided at a position slightly higher than the two surfaces of the stacked bundle 9'' of the front guide 2 that are in contact with the stacked bundle 9. This horizontal airflow discharge means 3 is made of a cylindrical body having an air discharge hole, and is arranged so as to blow the airflow 5 toward the vicinity of both front and both ends of the plate-like object 8 supplied to the accumulation section 5. has been done.

Therefore, the upper airflow 4 over the entire width of the plate-like object 8 moves the entire falling position of the front end of the plate-like object 8 toward the buffer means 7, and at the same time, the front end 8a of the plate-like object 8 comes into contact with the bundle 9 closest to the stacked bundle 9. Even the easy-to-reach parts can be lifted up by the horizontal airflow 5 and hit by the buffer means 7, making it possible to drop them onto the stacked bundle 9 with less impact due to the cushioning effect. Note that this buffer means 7 is designed to have an elastic force in the front-rear direction in the supply direction.
It is suitable that a rubber plate or the like is supported by 7a.

In other words, as shown in Figs.
An upward air stream 4 is discharged from the horizontal air stream 4 (FIG. 13A), and a horizontal air stream 5 is also discharged from the horizontal air stream discharge means 3 (FIG. 3B). Therefore, the front end 8a of the plate-shaped object is fed into the stacking section 15 without contacting the stacked bundle 9 (FIG. 3C), and the front end is stopped by the buffer means 7 (FIG. 3D). Furthermore, the plate-shaped object 8 is dropped into the accumulation section 15 using the air layer as a cushion.
A horizontal air flow 5 is discharged upwardly from the horizontal air flow discharge means 3, and cushion air 17 between the plate-shaped object 8 and the integrated bundle 9
is expelled from below the plate-like object 8 (Fig. 3E), and the plate-like object 8
are quickly accumulated on the accumulation bundle 9. In this way, in this embodiment, the front end 8a of the plate-like object 8 can be dropped onto the stacking bundle 9 through the cushion air and stacked without contacting the stacking bundle 9, thereby preventing damage to the plate-like object due to contact. At the same time, the cushion air can also be expelled at the same time, making it possible to achieve high-speed integration.
