Abstract

PURPOSE:To provide a stacking machine able to stack up articles to be stacked up, such as a heavy article and a long article, without damaging the article safely and with high workability. CONSTITUTION:An ejecting mechanism to move an article 12 to be stacked up, conveyed from a conveyance line 1, from the conveyance line 1 is provided. A laterally movable slide plate 19 protruded to a stacking-up position or a position above stacked up articles is provided, and the article to be stacked up from the conveyance line 1 is placed thereon. A stopper 20 is located such that the articles to be stacked up on the slide plate 19 are maintained in a stacking-up position or on already stacked up articles so that the article to be stacked up are not laterally moved togetherwith the slide plate during lateral movement of the slide plate 19.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking machine for stacking all kinds of rod-shaped objects such as materials, products, materials, etc. In particular, the present invention
This invention relates to a stacking machine for stacking objects that are difficult to stack manually or objects with shapes and lengths that are difficult to operate using industrial robots.

0002

[Prior Art] Conventionally, stacking of stacked items such as heavy or long items has been carried out by manually stacking them one by one, or by sliding the stacked items that have been moved laterally from the conveyor line over the tops of other stacked items. There is.

0003

[Problem to be solved by the invention] In this case, if the stacked items are lightweight or have shapes that are easy to handle, they will not pose a major hindrance to the work, and even if they are heavy or long items. ,
For example, pipes with round cross sections that are easy to roll can be stacked relatively easily.

However, when the steel material is rectangular and long in cross section, when the stacked products are slid on top of the stacked products as in the above-mentioned conventional method, scratches may occur due to mutual friction. When the items were slid, the parts that were previously stacked would collapse, making stacking difficult. Of course,
Although it is possible for workers to stack items manually or by using material handling equipment, there are major problems in the case of heavy items, such as danger, low workability, and a lack of manpower.

The present invention has been made in view of such circumstances, and is safe and easy to work with even for stacked items such as heavy objects and long items, and can be used automatically and without damaging the stacked items. The purpose of the present invention is to provide a stacking machine capable of stacking without any problems.

[0006]

[Means for Solving the Problems] According to the present invention, in a machine that automatically stacks stacked items such as materials, products, materials, etc., there is an extrusion method for moving stacked items flowing from a conveyance line from the conveyance line. a mechanism, a horizontally movable slide plate that protrudes from the stacking position or over the already stacked products and places the stacked products pushed out from the conveyance line, and when the slide plate is moved laterally,
To provide a stacking machine comprising a stopper for maintaining stacked products on a slide plate at a stacking position or above already stacked products so that the stacked products do not move laterally together with the slide plate.

[0007]

[Operation] The stacked products carried on the conveyance line are pushed by the push-out mechanism, move laterally from the conveyance line, and are transferred to the position to be stacked or to the slide plate that extends over the already stacked products. . When the specified number of horizontally arranged items are lined up on the slide plate, the stopper rises, and while preventing the horizontal movement of the stacked items on the slide plate, the slide plate is moved backward in the lateral direction and extracted. When this is the case, the stacked items are moved to the stacking position or onto the already stacked items, and the stacking is completed.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In the explanation, a steel material having a square cross-sectional shape will be specifically explained as an example.

FIGS. 1 and 2 show a conventional stacking machine. A square steel material 2 flowing on a roller conveyor 1 constituting a transport line stops at a predetermined position. The extrusion mechanism 6 moves laterally, and the square steel material 2 is pushed by the extrusion mechanism 6 and moves in the direction of the arrow until it touches the square steel material 7 that was stacked one cycle before and hits the stopper of the loading platform 3. While pressing , the square steel materials 5 are stacked by sliding on them. This is repeated, and when the specified number of horizontally arranged pieces are completed, the lifting mechanism 4 provided under the loading table 3 is lowered by one step, and the next square steel piece is stacked. If the square steel material is bent or distorted, stacking becomes possible by lowering the elevating mechanism 4 by an amount equal to the bending and distortion added to one tier.

[0010] In the above method, the ejected square steel material 2
Both the steel material 7 pushed by the steel member 7 slide on the steel material 5, so if the weight of the steel material is large or foreign matter is attached to the steel material, they will scratch each other and cause quality problems. Further, when sliding on the steel material 5, it may get caught at the corner and cannot be moved laterally, or the steel material 2 or 7 may fall down, making some of the stacked parts uneven in length and width.

3 and 4 show a stacking machine according to the invention. The square steel material 12 flowing on the roller conveyor 11 constituting the transport line stops at a predetermined position. The extrusion mechanism 16 moves laterally, and the square steel material 2 is pushed by this extrusion mechanism 16 and moves in the direction of the arrow, transfers from the roller conveyor 11 to the slide plate 19, and replaces the square steel material 1 that was on the slide plate 19 one cycle ago.
7 and move in the direction of the arrow while pushing this until it hits a stopper 18 provided on the loading table 13. The slide plate 19 has a thickness of several mm, is flexible, and is made of a material that does not damage the square steel material even if it rubs against the square steel material.

The lower surface of the slide plate 19 is in contact with the square steel members 15 already stacked, and the slide plate 19
The weight of the square steel members 12 and 17 placed on 9 is borne by the square steel member 15.

When the specified number of horizontal lines are lined up on the slide plate 19, the stopper 20 is raised, the slide plate 19 moves in the direction of the arrow, and the slide plate 19
The square steel members 12 and 17 on the slide plate 1
With the lateral movement of 9, it is transferred from the top of the slide plate 19 to the top of the square steel material 15, and the stacking is completed. Next, the elevating mechanism 14 below the loading platform 13 is lowered by one step, the slide plate 19 is moved again in the direction of the arrow, and the stopper 20 is lowered, completing preparations for stacking the next steel material.

In this method, the square steel members 12 and 17 do not directly slide on the square steel member 15, but all slide on the slide plate. If the material of the slide plate 19 is, for example, a nylon plate, a Teflon plate, or a brass plate, there is no fear that the steel material will be damaged. Also slide plate 19
Since it is a single plate, it may get caught when sliding on it,
There will be no troubles such as falling over and switching sides.

[0015]

[Effects of the Invention] As described above, by using the stacking machine according to the present invention, even bent or distorted materials can be stacked safely and reliably without damaging the stacked products or stacked materials. .
