Description

[Detailed description of the invention] (Industrial application field) The present invention is a sorting method in which the loads placed on each loading section on a slat conveyor are pushed out laterally at an arbitrary sorting position on the conveyor path. This relates to conveyors for industrial use.

(Prior art and its problems) As a conventional sorting conveyor, for example, a conveyor for conveying loads and a sorting pusher are synchronized with the conveyor, such as the device described in Japanese Patent Application Laid-Open No. 52-5250. It is known that pusher drive means for moving the pushers are arranged side by side in the horizontal direction, and guide rail means for moving each pusher laterally at the sorting position is provided. Such a conventional apparatus has the disadvantage that not only is the entire apparatus very wide and large, but it is also very expensive because a drive means for the pusher is required separately from the conveyor for transporting the load.

(Means for Solving the Problems) The present invention proposes a sorting conveyor that can solve these conventional problems, and its feature is that a slat conveyor is used as the load conveyor. A load pushing tool that can reciprocate in the width direction of the conveyor is attached to each load loading section on this slat conveyor, and each load pushing tool is moved through a driven roller provided so as to protrude below the slat. The sorting conveyor is provided with a guide rail means for horizontally moving each load pushing tool from a standby position on one side of the conveyor to a pushing position on the other side at an arbitrary sorting position on the conveyor path, , a plurality of pushers each movably supported on a different slat and arranged in series in the conveying direction, and a chain-like connector that connects the pushers to each other below the slats, and the chain-like connector supports each pusher. The link is connected to the link connecting pin of the slat drive chain by a connecting pin that is concentric and the same pitch, and the driven roller is pivotally supported on one link of this chain-like connecting device.

(Operations and Effects of the Invention) In the sorting conveyor described above, when the slat conveyor is driven, the load pushing tool located at the standby position on one side of each load loading section moves together with the slat. When a predetermined sorting position is reached, the load pushing tool is moved laterally on the slat from the standby position to the load pushing position on the other side by the guide rail means via the driven roller, and the load on the load loading section is moved laterally. push it out. At this time, a plurality of pushers constituting one load pushing tool move sideways together via the chain-like connector to perform a load pushing action. Further, the rotation of each slat and each pusher at the U-turn portion of the slat is smoothly performed by the bending of the chain-shaped connector.

According to the sorting conveyor of the present invention, the load pushing device consisting of a plurality of pushers arranged in series is directly supported by the slats of the slat conveyor for conveying loads and driven in the conveyance direction,
Since a separate drive means for the load pushing tool is not required, it can be implemented at low cost. Moreover, since the guide rail means for reciprocating the load pushing tool in the lateral direction is provided with foil inside the slat conveyor, the entire device is not wider than the width of the slat conveyor, and can be constructed compactly. I can do it.

Furthermore, since the load pushing device is composed of a plurality of pushers each supported by a different slat, the conveyor load of the entire load pushing device is reduced compared to the case of using a single pusher with one center portion supported by one slat. Even if the length in the conveyance direction is made longer (or wider) depending on the size of the load, sufficient strength can be provided. In addition, when using one pusher as described above, if the conveyor conveyance length of the pusher is increased, the rotation radius of both ends of the pusher becomes larger at the slat U-turn section of the slat conveyor, and the slat U-turn section However, the configuration of the present invention eliminates this inconvenience.

(Embodiment) An embodiment of the present invention will be described below with reference to the attached illustrative drawings. Reference numeral 1 denotes a slat installed between a pair of left and right drive chains 2, and each slat 1 corresponds to each slat on one side of the drive chain 2. It consists of three slat bars 5a, 5b, and 5c installed between brackets 4 attached to links 3, and each slat bar 5a
A guide groove 6 is formed in 5c over the entire length thereof. 7 is a pusher attached to each slat 1, and each slat bar 5a to 5
The three protrusions 8 that fit into the guide grooves 6 of c, the two protruding plates 9 that protrude below the slat bars from between each of the slat bars 5a to 5c, and the two protruding plates 9 on the lower side of the slat 1 are connected. The slat 1 is provided with a pusher detachment prevention plate 10, and is configured to be able to reciprocate between both ends of the slat 1 in the length direction. Reference numeral 11 designates a chain-shaped connector that connects three adjacent pushers 7 under the slats, and three links 13 that are connected by two connecting pins 12a and 12b.
a, 13b, 13c, each link 13
The detachment prevention plates 10 of three adjacent pushers 7, a to 13c, are connected via a shaft 14.
Two connecting pins 12 of this chain-like connector 11
a and 12b are arranged concentrically and at the same pitch as the connecting pin 15 that connects each link 3 of the drive chain 2. 16 is each link connecting pin 1 of the drive chain 2
5 and is supported by a guide rail 17.

18 is the central link 13 of each chain-like connector 11;
A groove-shaped main guide rail 19, a branch guide rail 20, and a sub-guide rail 21 that guide the driven roller 18 in the conveyance path for conveying the load on the slat 1. , and a return guide rail 22 are installed. The main guide rail 19 is a guide rail that holds the pusher 7 at a position A above one end of the slat 1, and the branch guide rail 20 is
As the slat 1 moves, a load pusher 23, which is composed of three pushers 7 branched from the main guide rail 19 and connected by a chain-like connector 11, and located at each load loading section on the slat conveyor, is operated. These are diagonal crossing guide rails for laterally moving the slats to the upper position B on the other end thereof, and are arranged in parallel at the same interval as the interval between the load pushing tools 23 (the interval between the driven rollers 18). The sub guide rail 21 is connected to the slat 1
It is a guide rail that holds the load pushing tool 23 at the upper position B of the other end, and the return guide rail 22
connects the sub-guide rail 21 to the main guide rail 19 at the end of the conveyance path, and returns the load pusher 23 from the B position to the A position. As shown in FIG. 1, means 24 for changing the traveling direction of the driven roller 18 is provided at each branch point of the branched guide rail 20 with respect to the main guide rail 19. This switching means 24 is composed of a switching movable piece 25 and a rotary solenoid 26 that drives the switching movable piece 25.

In addition, in the return path portion of the slat 1, guide rails are provided that connect both ends of the main guide rail 19 provided on the conveyance path.

Next, the method of use and operation will be explained. When the drive chain 2 is rotated by the drive gear wheel 27 at the end of the conveyance path shown in FIG. 2, the slat 1 on the conveyance path is moved in the direction of the arrow 28. At the starting end of the conveyance path, all the load pushing tools 23 are at position A above one end of the slat because the driven rollers 18 are guided by the main guide rail 19. At the starting end of the transport path, the objects to be transported are transferred and placed on the slat 1 at positions facing each of the load pushing tools 23. The conveyed object is conveyed in the direction of the arrow 28 as the slat 1 moves, and the load pusher 23 located on the side of the conveyed object moves it to one of the sorting destinations set for each branch guide rail 20. , when reaching just before the position corresponding to the selected specific sorting destination, that is, the specific branching point of one branching guide rail 20 corresponding to the specific sorting destination and the branching point of the branching guide rail 20 immediately before. The specific load pushing tool 23 is installed in the section of the main guide rail 19 between the point
When the driven roller 18 belonging to the specific branch point reaches, the switching movable piece 25 of the driven roller traveling direction switching means 24 at the specific branch point is switched by the rotary solenoid 26 to cause the driven roller 18 to enter the branch guide rail 20. As a result, the driven roller 18 enters the branched guide rail 20 from the main guide rail 19, and the driven roller 18 enters the branched guide rail 20 from the main guide rail 19.
3 connected by a chain-like connector 11 with
As the slat 1 advances, the two pushers 7, that is, the load pushing tools 23 move to a position B above the other end of the slat 1.
Move sideways towards. Therefore, this load pushing tool 23
The objects to be conveyed on the slat 1 at the position facing the slat 1 are pushed out from the slat conveyor to a specific sorting destination by the load pushing tool 23.

The load pushing tool 23, which has finished pushing out the conveyed object and reached the upper position B of the other end of the slat, is held at the B position by the driven roller 18 moving within the sub-guide rail 21, and reaches the end of the conveying path. At this point, the driven roller 18 is returned to the main guide rail 19 by the return guide rail 22, so that the load pushing tool 23 at position B automatically rotates around the drive gear 27. When moving to the return route, or when making a U-turn from the return route to the conveyance route, each pusher 7 in the load pusher 23 moves from the slat 1 as the drive chain 2 bends at the link connecting pin 15. At the same time, the chain-shaped connector 11 that connects each pusher 7 also rotates relatively around the link connecting pin 15, and the connecting pins 12a, 1 concentric with the link connecting pin 15 of the drive chain 2.
Since it is bent around 2b, the load pushing tool can be rotated without any problem.

Incidentally, since the intervals between the load pushing tools 23 and the distances between the branch guide rails 20 are made equal, a plurality of adjacent load pushing tools 23 can be simultaneously and integrally moved across to the B position. Therefore, a long object to be conveyed in the conveyance direction is transported by a plurality of load pushers 23.
It can also be used to push out to two sorting destinations. Moreover, the sub-guide rail 21 and the return guide rail 22 are not essential requirements. If these guide rails 21 and 22 are not provided, at the end of the return path of the slat 1, the driven roller of the load pusher 23 located at or near position B is guided to the starting end of the main guide rail 19 by a guide plate or the like. All you have to do is configure it to do so.

In the above embodiment, each load pushing tool 23 is placed in a standby position on the side of the conveyor (position A above one end of the slat 1) at an arbitrary sorting position on the conveyor path.
The guide rail means for moving the slat horizontally from the main guide rail 19 to the push-out position on the other side (the upper position B of the other end of the slat 1) includes the main guide rail 19 and the branch guide rail 2.
