Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention conveys an article on a slat by moving a large number of slats, and pushes the article by a moving shoe provided on each slat onto a predetermined chute. A sorting device for sorting.

[0002]

2. Description of the Related Art As a conventional sorting apparatus, as shown in FIG. 5, an article 60 is conveyed by moving a large number of slats 61, and a direction changing shoe 62 provided on each slat 61 is moved along the slats 61. By doing so, the articles 60 on the slats 61 are pressed at a predetermined position for each article 60 and discharged onto the sorting spar 63 on the side in the carrying direction (arrow A direction) for sorting (see Japanese Patent Laid-Open No. 5-1.
(See Japanese Patent No. 93735).

Each direction-changing shoe 62 is slidably supported by the slats 61 in the longitudinal direction (left and right direction in FIG. 5), and when the articles 60 are conveyed by the movement of the slats 61, the guide pins 64 are provided. Is guided by a guide track 65 provided along the transport direction A, and moves in the transport direction together with the slats 61. Then, a plurality of the direction change shoes 62 adjacent to the transport direction A are introduced into the predetermined direction change track 66 by the direction change gate (not shown) along the path of the guide pin 64 at a predetermined position of each article 60. Can be switched to. That is, each of the direction change shoes 62 is introduced into the corresponding direction change track 66 by simultaneously operating a plurality of direction change gates adjacent to each other in the transport direction A. As a result, each of the direction changing shoes 62 slides along the slats 61 and presses the articles 60 on the slats 61, and the articles 60 are discharged and sorted on a predetermined sorting spar 63.

[0004]

In the conventional sorting apparatus described above, the sorting spar 63 is arranged obliquely to the transport direction A, and the sorting direction of the articles 60 is
It is diagonally forward with respect to the transport direction A. Therefore, the article 6
When 0 is a cylindrical object, a long object, or the like and is conveyed in a state where the longitudinal direction is along the conveying direction A, the articles 60 sorted on the selection spar 63 by the direction changing shoes 62.
The posture is such that the longitudinal direction obliquely intersects the carrying-out direction (arrow B direction) of the article 60 by the sorting spar 63. Therefore, the articles 60 are conveyed by the selection spar 63 in a posture in which the longitudinal directions intersect diagonally, which hinders the subsequent handling of the articles 60 and lowers the sorting efficiency. That is, for example, when the article 60 is to be stored in the bucket (not shown) from the selection spar 63, the longitudinal direction of the article 60 and the longitudinal direction of the bucket are aligned at the end portion (not shown) of the selection spar 63. Since it is extremely difficult to store the article 60 in the bucket, or even if it is possible to store the article 60, there is a problem that the storage efficiency of the article 60 in the bucket is extremely low. Moreover, since the installation direction of the sorting spar 63 is oblique to the transport direction A, it is necessary to secure a considerably large space along the transport direction A. Therefore, the space efficiency along the transport direction A is low, and a narrow warehouse. It was a serious problem in a limited space such as inside.

According to the present invention, an article on a slat is placed on a predetermined chute along a direction substantially orthogonal to the conveying direction of the article.
An object of the present invention is to provide a sorting device capable of sorting in a predetermined posture and ensuring high space efficiency along the article transport direction.

By moving the slat along the longitudinal direction, the articles on the slat are pressed to sort the articles from the slat onto the predetermined chute, and the branch rail. And switching means which are respectively provided at positions branching from the main rail and are operated in synchronization with a predetermined number of each chute so as to synchronously introduce a predetermined number of moving shoes from the main rail to each branch rail. It is achieved by a sorting device characterized by that.

[0007]

In the sorting apparatus according to the present invention, the chute is
A plurality of articles are provided at predetermined intervals in the article conveyance direction along a direction substantially orthogonal to the article conveyance direction. The main rail is provided along the transportation direction of the article. A plurality of branch rails are provided for each chute at predetermined intervals in the article transport direction and are branched from the main rail. Each of the moving shoes is guided by the main rail to move in the article conveying direction together with the slats, and is guided by the branch rails to move along the longitudinal direction of the slats to press the articles on the slats. Then, the articles are sorted from the slats onto a predetermined chute. The switching means are respectively provided at locations where the branch rails branch from the main rail, and by operating a predetermined number of each chute in synchronization, a predetermined number of moving shoes are synchronized to each branch from the main rail.

Each of the moving shoes 30 is shown in FIG.
As shown in FIG. 3, a cap portion 32 is provided on the upper surface of a slide portion 31 slidably supported so as to surround the slat 20, and the cap portion 32 is slid on the slat 20 as the slide portion 31 slides. The article 10 is pressed. A guide pin 33 is provided on the lower surface of the slide portion 31. A guide roller 34 is rotatably supported by the guide pin 33 in a substantially horizontal state.

With reference to FIGS. 1-3, each set of moving shoes 30 is moved by the movement of the slat 20 into the article 1.
When 0 is conveyed, the guide roller 34 is guided by the main rail 40 provided along the conveyance direction A, and the slat 2
It moves in the transport direction A together with 0. Then, the moving shoes 30 of each set are synchronously switched at a predetermined position for each article so that the path of the guide roller 34 is introduced into the required branch rail 41 by the switching mechanism 50.
As a result, each moving shoe 30 has a sliding portion 3
1 slides along the slat 20 and synchronously presses the article 10 on the slat 20 to push the article 10 into a predetermined chute 4
2 Dispose on top and sort.

The main rails 40 are provided along the carrying direction A on both sides of the carrying frame 11 in the carrying direction A of the article. Each of the main rails 40 guides the moving shoe 30 in the transport direction A by engaging a guide roller 34. The branch rail 41 is for each chute 4
A plurality of every two (6 in the present embodiment) are spaced at predetermined intervals in the transport direction A, and each branch from the main rail 40 on the right side of the transport direction A toward the left diagonally forward, and the main rail on the left side of the transport direction A. It is provided so as to merge with 40. Branch rail 41
Guides the moving shoe 30 diagonally forward left in the transport direction A, so that the moving shoe 30 slides along the slat 20 and the article 10 is carried out from the slat 20 onto a predetermined chute 42.

The chute 42 is composed of a roller conveyor or the like, and a plurality of chutes 42 are provided at predetermined intervals in the carrying direction A along a direction (left in FIG. 1) substantially orthogonal to the carrying direction A of the slats 20. The chute 42 is a moving shoe 30.
The article 10 transferred from the slat 20 is conveyed to a bucket or the like (not shown) arranged at the end portion.

The switching mechanism 50 has a predetermined interval Np at each branch rail 41 branching from the main rail 40.
It is opened. The switching mechanism 50 is provided for each chute 42.
A predetermined number (six in this embodiment) of each of the guide rollers 34 of the moving shoes 30 of each set (six in this embodiment) of the main rails are synchronously operated. Four
It is introduced into the branch rail 41 from 0. The installation pitch Np of the switching mechanism 50 is an integer N times the slat pitch p (in this embodiment, approximately the same size).

Referring to FIGS. 1 and 4, the switching mechanism 50.
In the above, an electromagnet 51 is provided at a location where each branch rail 41 branches from the main rail 40.
Is excited based on various sort information and a detection signal of the guide roller 34 by the two pairs of sensors 52 provided at a predetermined interval L, and the guide roller 3 made of a magnetic material.

That is, when the sorting is not performed, the electromagnet 51 is not excited, the guide roller 34 of the moving shoe 30 goes straight without the course being changed by the electromagnet 51, and is conveyed along the main rail 40 in the conveying direction A. (The moving shoe 30 shown by the solid line in FIG. 4). On the other hand, when sorting is performed, the electromagnet 51 is excited and the guide roller 34 of the moving shoe 30 is changed in course by the electromagnet 51. The guide roller 34 whose path has been changed is further guided by the magnetic action of the permanent magnet (or electromagnet) 53 to the branch rail 41 (moving shoe 30 shown by a chain double-dashed line in FIG. 4). The electromagnet 51 and the permanent magnet (or electromagnet) 5
3 are connected by a yoke 54 made of a magnetic material,
The yoke 54 continuously connects the main rail 40 and the branch rail 41 so as to draw an arc, and smoothly moves the guide roller 34 of the moving shoe 30.

The operation of this embodiment will be described. Slat 20
The article 10 placed on the slat 20 is conveyed in the conveyance direction A by the movement of the slat 20, and is pressed by the moving shoe 30 at a predetermined position for each article 10 and is conveyed from the slat 20 onto a predetermined chute 42. Be sorted.

That is, in each set of moving shoes 30,
When the articles 10 are transported by the movement of the slats 20 and the sorting is not performed, the switching mechanism 50 is not operated,
As a result, the guide rollers 34 are guided by the main rails 40 without changing their paths and move in the transport direction A together with the slats 20.

On the other hand, when the articles 10 are sorted, the six switching mechanisms 50 of the corresponding chutes 42 are operated in synchronization. As a result, each pair of moving shoes 30
The guide rollers 34 are changed in their paths synchronously, and are guided to the branch rail 41 by the magnetic action of the permanent magnet (or electromagnet) 53. The moving shoes 30 in which the guide rollers 34 are introduced into the branch rails 41 are
As the slide portion 31 slides, they move in synchronization along the slat 20, and the cap portion 32 presses the article 10 on the slat 20 almost at the same time. Pressed article 10
Are carried out from the slats 20 and sorted on a predetermined chute 42 along a direction substantially orthogonal to the carrying direction A. At this time, even when the article 10 is a cylindrical long object or the like and is placed on the slat 20 in a state where the longitudinal direction does not follow the transport direction A, the cap portion 3 of the moving shoe 30.
By being pressed almost simultaneously by 2, the posture is corrected so that the longitudinal direction is along the transport direction A.

As described above, according to the above-described embodiment, the switching mechanism 50 is arranged so that the installation pitch Np is an integral multiple of the slat pitch p, and six chutes 42 are operated in synchronization. And the guide roller 3 of the moving shoe 30

1, so that the moving shoes 30 slide along the slats 20 in synchronization with each set. Therefore, for example, an article 10 such as a cylindrical long object is moved in the longitudinal direction in the transport direction A
Even when the articles 10 are placed on the slats 20 and conveyed along the chute 42 when the articles 10 are not sorted,
The posture of the article 10 can be corrected so that the longitudinal direction of the article is along the transport direction A. That is, for example, when an article is to be stored in the bucket from above the chute 42, it is extremely easy to match the longitudinal direction of the article and the longitudinal direction of the bucket at the terminal end portion of the chute 42, and the article is stored in the bucket. Can be stored efficiently.
As a result, the articles 10 on the slats 20 can be sorted on a predetermined chute 42 in a predetermined posture. Further, since the chute 42 is provided along the direction substantially orthogonal to the transport direction A, high space efficiency can be secured along the transport direction A.

In the above embodiment, six switching mechanisms 50 are used.
It is configured such that the path of the moving shoes 30 is changed in synchronization with each set by operating the switching mechanisms in synchronization with each other. By doing so, the course of the moving shoes 30 may be configured to be changed synchronously in pairs adjacent to each other in the transport direction A. According to this, the position of the article 10 having a relatively small outer dimension on the chute 42 can be set in advance, whereby the articles 10 can be aligned in a plurality of rows on the chute 42, and the accommodating capacity of the chute 42 can be set. Can be improved.

[0023]

As described above, according to the present invention, a plurality of chutes are provided at predetermined intervals in the article conveying direction along a direction substantially orthogonal to the article conveying direction, and
The switching means are respectively provided at locations where the branch rails branch from the main rail, and by operating a predetermined number of each chute in synchronization, a predetermined number of moving shoes are synchronized to each branch from the main rail. Since the rails are introduced into the rails, the articles on the slats can be sorted on a predetermined chute in a predetermined posture, and high space efficiency can be secured along the article transport direction.
