Abstract

PURPOSE:To simplify the construction and to improve the durability of a sorting device installed in the middle of a straight advance belt conveyer by disposing a sorting belt conveyer capable of turning in the horizontal direction between straight advance conveyers, thereby to obliquely distribute an article. CONSTITUTION:When an article conveyed in direction of an arrow P on a straight advance belt conveyer 1 is transferred onto a sorting belt conveyer 2, if the article is discharged to the upper left along the sorting direction, the sorting belt conveyer 2 is turned counter-clockwise through an operating device not shown to match with the upper left discharge sheet 6a. Subsequently, the belt conveyer 2 is driven to discharge the article in direction of an arrow L. This arrangement can simplify the construction and improve the durability.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device for a belt conveyor installed midway on a straight belt conveyor line. For these types, it is difficult to determine the speed before and after the sorting time, that is, the timing ia1* of the conveyance speed and the sorting operation speed, and the mechanism of the sorting device itself. The belt conveyor sorting device of the present invention was proposed with the aim of solving the above-mentioned problems. A sorting belt conveyor, in which the conveyor frame is horizontally swingable with respect to a frame near the center, is installed between a plurality of straight belt conveyors installed in a horizontal direction. It is characterized in that it is equipped with an actuation device that displaces the sorting belt conveyor diagonally to the right or left. Further, in the sorting device of the specific invention, a second invention is provided in which the sorting belt conveyor has a structure formed between its base end and the straight belt conveyor when the sorting belt conveyor is displaced from the straight position to the discharge position. This is characterized by the provision of a complementary member that complements the planar gap.

The present invention will be explained below based on the embodiments shown in the drawings.
In FIGS. 1 to 3, l indicates a plurality of straight belt conveyors in a straight belt conveyor line, and the straight belt conveyors 1 are installed intermittently and fixedly at appropriate intervals. The conveyor belt (1m) of the belt conveyor I is driven in the conveyance direction P of articles (not shown) by a drive device (not shown).

2 is a sorting belt conveyor installed between two adjacent linear belt conveyors 1, 1. The conveyor frame 21c of each sorting belt conveyor 2 is fixed with an iK rocking table 22 under it, and it is assembled so as to be able to swing in the horizontal direction via the rocking table 22 to a pedestal 23 at the lowermost part of the conveyor frame 2a. The conveyor belt of the belt conveyor 2, 2b is the drum at both ends, 2c is the bearing of the drum 2b, and the conveyor belt 21 is
A rotational force is applied to the drive drum 2b from a motor or other drive device 24 provided on the rocking table 22 or the conveyor frame 21 via a well-known transmission device 25, thereby rotating the drive drum 2b in the direction of arrow P. Note that 9 is a sensor that sends a signal to the electric control device regarding the presence or absence of conveyed articles.

A rotary shaft 3 is fixed to the lower surface of the rocking table 22 fixed to the conveyor frame 211C, and the rotary shaft 3 is connected to the pedestal 2.
3 through a bearing 31 so that the sorting belt conveyor 2 as a whole including the swing table 22 is swingably supported on the pedestal 23 .

An arm 32 is fixed to the rotating shaft 3, and the distal end of the hydraulic cylinder device or other actuating device 4 is pivotally attached to the distal end of the arm 32. actuation device,
That is, the base end side of the fluid pressure cylinder device 4 is pivotally attached to a mounting member 5 fixedly installed on the pedestal 23 via a bracket 51. Note that two of the fluid pressure cylinder devices 4 may be provided in pairs on both sides of the pedestal 23 in order to smoothly and stably perform the swing displacement action of the sorting belt conveyor 2, which will be described in detail later. good. In that case, the distal end side of the hydraulic cylinder device 4.4 is pivotally connected to each end of an arm 32 provided so as to project from both sides.

In the belt conveyor assembly sorting device of the present invention configured as described above, as shown in FIGS. 1 and 2, each sorting device is The belt conveyor 2 can be displaced diagonally to the right or left from the straight line position indicated by the solid line, for example, approximately 456 degrees horizontally, and if explained with reference to FIG.
a s 6b % Items are arbitrarily discharged and sorted into 6e or 6d.

In FIGS. 2 and 3, in terms of the sorting of articles, when it is desired to discharge articles conveyed on the straight belt conveyor 1 in the direction of arrow P, for example in the diagonal left direction, an actuating device is used. The piston of the fluid pressure cylinder device 4 is contracted, and the pedestal 2 is moved through the arm 32 and the rotating shaft 3.
3, the sorting belt conveyor 2 and the rocking table 22 are rotated about 45@ to the left. That is, since the sorting belt conveyor 2 changes its position by swinging diagonally to the left from the straight forward position shown by the solid line to the discharge position shown by the chain line, the articles are discharged and sorted in the direction of the arrow. On the contrary, 1
If it is necessary to discharge the articles diagonally to the right, the piston of the hydraulic cylinder device 4 may be extended, and the articles are discharged and sorted in the direction of arrow R (see FIG. 1) K. In order to convey the articles in a straight line, the piston of the hydraulic cylinder device 4 may be returned to its original position, and the sorting belt conveyor 2 may be returned to the straight line position.

As shown in FIG. 3, in the embodiment, the conveying surface of the bell 2a of the sorting belt conveyor 2 is inclined so that it is lower on the front side and higher on the rear side. This is to ensure that goods can be transferred from conveyor belt 1 to conveyor belt conveyor 1 or to conveyor belt conveyor 1 at the rear.

In this sorting device, a certain distance is provided between each sorting belt conveyor 2 and the front and rear linear belt conveyors 1, 1 so that they do not interfere with each other when the sorting belt conveyor 2 swings. This interval is based on the sorting belt conveyor 2.
When the container is oscillated and placed in the discharge position, some problems arise in transferring one article to another. That is, if the article is small, the article may jump up in the triangular space @S formed between the sorting belt conveyor 2 and the straight belt conveyor 1 in front. In the second invention, in order to complement the triangular planar gap x, as shown in FIGS. 7 (representing 7m, 7bt) is fixedly installed.

The illustrated example includes a crescent-shaped complementary member 7a fixed to the front of the conveyor frame 21, and triangular complementary members 7b, 7b fixed to both front sides of the conveyor frame 21. Of course, these are made in such a shape that they do not collide with the straight belt conveyor 1 when the sorting belt conveyor 2 is oscillated. These flat plate-shaped complementary members 7 can be installed so as to be several times lower than the 2 m conveyance surface of the sorting conveyor 2. Further, it is preferable to provide a side plate 8 extending substantially perpendicularly upward from the rear outer edge of the triangular complementary member 7b to the rear half of the conveyor frame 21. Each side plate 8 can serve as a guide plate to prevent articles from flying out when the sorting conveyor 2 is moved to the discharge position.

FIG. 4 shows a sorting device in which the sorting belt conveyor 2 is swung only diagonally to the right.

According to this embodiment, the articles conveyed from the straight belt conveyor 1 are discharged and sorted only in the direction of arrow R. Therefore, it is sufficient to provide the triangular complementary member 7b only on the front right side of the conveyor frame 21. Further, in this example, the side plate 8 on the left side with respect to the conveyance direction P for preventing popping out is directly fixed to the outer surface of the conveyor frame 21. It should be noted that the members indicated by the same reference numerals in FIG. 4 as in FIGS. 2 and 3 have the same effect as the members in FIGS. 2 and 3, so a detailed explanation thereof will be omitted.

The belt conveyor sorting device of the present invention described above has a simple structure and is extremely durable, and the means for conveying the articles before and after sorting are both constructed of the same type of belt conveyors 1 and 2. As a result, the timing of sorting operations can be easily adjusted. (9) During sorting operation, the gap S formed between the straight belt conveyor 1 and the sorting belt conveyor 2 can be closed by the complementary member 7, so even if the conveyed articles are small, they will not jump up. It has the advantage of not having to be unloaded.
