The slat frame 1 is arranged continuously along a circulation path 2 described later and is movable in the front-back direction in the drawing. A slider 3 that is movable in the direction of both ends of the slat frame 1 on the left and right in the figure, which intersects with the moving direction of the slat frame 1, is provided at the lower part of 1.

Then, one or more constant rollers 4, two constant rollers 4 in the example of FIG. 1 and two constant rollers 4 in the example of FIG. 2 are arranged parallel to each other at both ends of the slat frame 1. In addition to being pivotally supported, two or more moving rollers 5 are also pivotally supported on the slider 3 in the example of FIG. 1 and the example of FIG.

In addition, a middle portion of the support belt 6 formed of a flat belt having a left-right conveyance direction intersecting with the moving direction of the slat frame 1 is arranged above the slat frame 1. Both ends of the support belt 6 are alternately folded around the fixed rollers 4 at both ends and an intermediate moving roller 5 corresponding to the fixed rollers 4, and then, in the example of FIG. Both ends of the frame 1 are fixed to the slider 3 in the example of FIG.

In this structure, the slider 3 is provided with, for example, a roller 7 axially supported on the lower portion of the slider 3 or an engaging body such as a pin 8 that axially supports the roller 7 and projects to the lower portion of the roller 7 in the circulation path 2. When it is moved in the left-right direction by pushing it by an operating means 9 provided later, the constant roller 4 acts like a constant pulley and the moving roller 5 acts like a moving pulley, and the upper portion of the slat frame 1 follows the principle of the pulley. An intermediate portion of a certain support belt 6 is an integral multiple of the moving stroke S of the slider 3, in the direction opposite to the moving direction of the slider 3, a double stroke 2S in the example of FIG. 1, and in the example of FIG. 3x stroke 3S Move.

Therefore, when the article W is supported on the intermediate portion of the support belt 6 above the slat frame 1, the article W can be conveyed along the circulation path 2 by the movement of the slat frame 1. W can be carried out to the side of the circulation path 2 in which the slat frame 1 moves by the movement of the slider 3.

In the example of FIG. 1, as shown in (A), the product W is supported on the middle portion of the support belt 6 above the slat frame 1 with the slider 3 positioned at one end of the slat frame 1. Then, when the slider 3 is moved to the other end in the slat frame 1 from the state shown in (A) to the state shown in (B), as shown in (C), the article W is completely removed. Can be carried to the side.

In the example of FIG. 1, the fixed rollers 4 on both sides of the slat frame 1 are two on each side, a total of four, and the moving rollers 5 of the slider 3 are the same four. When the roller is hung around, the middle part of the support belt 6 on the upper part of the slat frame 1 moves four times the stroke of the slider 3. Similarly, when the rollers 4 and 5 are increased, the middle part of the support belt 6 moves to the slider 3. Strokes that are even multiples of 6 times, 8 times ...

Further, in the example of FIG. 2, as shown in (A), the product W is supported on the middle portion of the support belt 6 above the slat frame 1 with the slider 3 positioned at the center of the slat frame 1. From the state shown in (A), if the slider 3 is moved to the left end side in the slat frame 1 as shown in (B), the article W can be completely discharged to the right end side, and conversely, When the slider 3 is moved to the right end side in the slat frames 1a and 1b from the state shown in (A) as shown in (C), the article W can be completely carried out to the left end side.

In the example of FIG. 2, the fixed rollers 4 at both ends of the slat frames 1a and 1b are set to three on each side, a total of six, and the number of moving rollers 5 of the slider 3 is reduced by two to four, and the rollers are arranged vertically. When the support belt 6 is hung around, the middle part of the support belt 6 above the slat frames 1a, 1b moves 5 times the stroke of the slider 3, and when the rollers 4, 5 are increased in the same manner, the support belt 6 moves. The middle portion moves a stroke that is an odd multiple of 7 times, 9 times ...

3 to 6 show details of the triple stroke type slat frame 1 of the example of FIG.

The slat frame 1 is composed of a frame member 11 having an inverted U-shaped cross section, the lower part and both ends of which are open. The lower ends of both ends of the frame member 11 constitute a pair of endless chains that form the circulation path 2. It is adapted to be attached to the connector 12 via the plate 13.

Contrary to the frame member 11, the slider 3 has an inverted U-shaped cross-section with its upper portion and both ends opened, and both sides of the slider 3 are provided inside the frame member 11. It is engaged with a pair of guide rail portions 16 via a plurality of bearing balls 17, and is thereby supported so as to be movable at right angles to the moving direction of the slat frame 1.

The fixed roller 4 is pivotally supported by brackets 20 attached to both ends of the frame member 11, and an intermediate portion of the support belt 6, that is, a portion for supporting the article W is an upper portion of the frame member 11. Supported by.

Further, the roller 7 as the engaging body is pivotally supported on the lower end of the projection 23 provided at the lower portion of the slider 3 via the pin 8 as the engaging body. It projects below the frame member 11.

7 and 8 show a circulation path 2 along which the slat frame 1 moves.

The circulation path 2 is formed by endlessly chaining a pair of endless chains 12 on both sides around sprocket wheels 26 on both sides, and is formed in an endless shape. On both ends of a large number of slat frames 1 are attached in parallel to each other in a state in which they are almost in close contact with each other with no space therebetween, and the support belts 6 of these slat frames 1 form a substantially continuous conveying surface. By synchronously driving the pair of chains 12 on both sides by the sprocket 26 on the right side in the figure, a large number of the slats 1 are cyclically moved together with the chains 12 in the clockwise direction in FIG.

In the upper horizontal moving portion of the circulation path 2, an operating means 9 for driving the support belt 6 by laterally moving the roller 7 and the pin 8 under the slider 3 of the slat frame 1 is provided. ing.

The actuating means 9 is composed of a movable switching guide 29 that horizontally rotates with an air cylinder about an unillustrated shaft, a fixed switching guide 30, and a fixed switching rail 31, and each slat frame 1, and the movable switching guide 29 is rotated clockwise or counterclockwise from the state shown in FIG. 7 during the operation, which causes the circulation path to move as the chain 12 moves. 2 The roller 7 and the pin 8 which have been moving between the guide rails 32 at the central portion are engaged with the groove 29a of the movable switching guide 29 and the pin 8, and subsequently the pair of grooves 30a on both sides of the fixed switching guide 30. By engaging any one of the above with the pin 8 and further engaging the fixed switching rail 31 with the roller 7, it moves between the guide rails 33 on one side or the other side of the circulation path 2, and by this movement, Circulate the support belt 6 2 can be driven towards the other side or one side, and when inactive, the groove 29a of the movable switching guide 29 leads to the central groove 30b of the fixed switching guide 30, whereby The rollers 7 and the pins 8 which have been moving between the guide rails 32 are continuously moved as they are between the guide rails 32 so that the support belt 6 is not driven.

Then, in this transfer / sorting apparatus, a large number of slat frames 1 along with the pair of chains 12 on both sides are circularly moved counterclockwise in FIG. 8 along the circulation path 2 and are moved in this state. The articles W are placed on the upper portions of the plurality of slat frames 1, and the articles W are supported on the intermediate portions of the support belts 6 of the plurality of slat frames 1. The articles W are moved to the right in FIG. Transport to.

When the actuating means 9 is actuated, the support belt 6 of the slat frame 1 is driven, and the article W on the support belt 6 can be carried out to one side or the other side of the circulation path 2. If the actuating means 9 is not operated, the slat frame 1 carrying the article W is not driven and the article W can be conveyed as it is.

Therefore, the articles W carried on the support belt 6 of the slat frame 1 can be laterally carried out and sorted for each product type or each shipping destination.

The roller 7 and the pin 8 below the slider 3 of the slat frame 1 are returned to the central portion of the circulation path 2 by an operating device (not shown) while moving the lower horizontal movement portion of the circulation path 2. It has become.

Further, in this embodiment, the roller 7 and the pin 8 are used as the engaging body, and in response to this, in the actuating means 9, the switching guide 29 and the small diameter pin 8 are engaged first. , This is because compared to the large diameter roller 7, the smaller diameter pin 8 has less shock to start the operation and can move quickly. At the position, noise is prevented by engaging the switching rail 31 and the guide rails 32 and 33 with the rotatable roller 7.

Further, in the actuating means 9, in addition to the movable switching guide 29, the fixed switching guide 30 and the switching rail 31 are used, and the movable switching guide 29 is shortened, so that the pin 8 is movable. As the time for moving the slat 29 is shortened, therefore, as soon as the slat frame 1 carrying the article W passes the movable switching guide 29, the switching guide 29 can be immediately returned to respond to the next operation.
