However, in this type of conventional transport device for sorting,
Even if the sorting belt conveyor provided on the traveling carriage is configured to be driven by a linear motor as disclosed in JP-A-57-9606, the conveyor driving motor is mounted on the traveling carriage. Since it is installed, not only is it necessary to increase the size and weight of the traveling vehicle, but also the power supply means for the motor on the traveling vehicle must be arranged along the traveling route of the vehicle, which greatly reduces equipment costs. The result is expensive.

(Means for Solving Problems) The present invention proposes a sorting conveying device capable of solving the above problems, and is characterized by using a slat conveyor as a sorting conveyor on a traveling carriage. use,
The slat plate of the slat conveyor is configured as a secondary conductor plate of the linear motor, and at each sorting position set in the traveling path of the traveling carriage, the slat plate is provided on the lower side of the slat conveyor and on the lower side of the slat conveyor. A primary coil for a linear motor, which is located at a predetermined gap and propels the facing slat plates in the lateral direction, is provided.

(Operation of the Invention) In the above-described sorting / transporting apparatus according to the present invention, each cart is run on the sorting slat conveyor while supporting the transported object, and the destination of the loaded transported object is sorted. When the truck arrives at the vehicle, the primary coil for the linear motor of the sorting destination is energized, and the primary coil is attached to the slat plate (secondary conductor plate for the linear motor) in the lower return path of the passing slat conveyor of the truck. The magnetic action between and directly gives a lateral and lateral propulsive force, whereby the slat conveyor can be rotated in a predetermined direction to carry out the carried object to be laterally and laterally carried out. .

(Example) Hereinafter, one example of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a traveling carriage endlessly connected by a universal joint 2, each of which has a supporting horizontal shaft wheel 3 and a steady-state vertical shaft roller 4 provided outside the axial center of the wheel 3, It is supported by an endless guide rail 7 that forms an upper sorting conveyance path 5 and a lower return path 6. Reference numeral 8 is a bellows-like cover that covers the connecting portion between the traveling carriages 1.

Reference numeral 9 denotes a linear motor as a bogie propulsion means, which is provided on both side plates 10 of each traveling bogie 1 on the secondary conductor plates 11a and 11b attached in parallel to the traveling direction and on the support frame 12 on the guide rail 7. It is composed of primary coils 13a and 13b attached so as to form a proper gap between the secondary conductor plates 11a and 11b.

A sorting slat conveyor 14 is installed on each of the traveling carriages 1 in a lateral direction orthogonal to the traveling direction. In this slat conveyor 14, a slat plate 17 is mounted between a pair of chains 16 suspended between a pair of idler wheels 15a and 15b, and each slat plate 17 is a secondary conductor of a linear motor. It is composed of plates.

On the other hand, sorting positions 18 are set at appropriate intervals on the upper sorting and conveying path 5 on which the carts 1 run in an upright posture. A chute 19 for receiving an object is arranged so as to be connected to the carry-out end. A linear motor 20 for driving the sorting slat conveyor 14 is arranged at each sorting position 18.

This linear motor 20 uses a slat plate 17 of a sorting slat conveyor 14 on each traveling carriage 1 as a secondary conductor plate, and when the traveling carriage 1 arrives at each sorting position 18, the carriage The linearly arranged laterally right and left below the lower return path of the slat plate 17 of the sorting slat conveyor 14 so as to face each slat plate 17 with an appropriate gap. Primary coil for motor
It has 21. The primary coil 21 is mounted on the support frame 12 on the guide rail 7. Reference numeral 22 is a protective cover made of plastic or the like for covering the primary coils 13a, 13b, 21 on the guide rail 7 side.

In the sorting transport device configured as described above,
By energizing each of the primary coils 13a, 13b installed on the guide rail 7 side of the carriage propelling linear motor 9,
The thrust in the traveling direction of the carriage acts on the secondary conductor plates 11a and 11b on the side of each traveling carriage 1, so that each traveling carriage 1 travels along the guide rail 7 in a predetermined direction.

Therefore, at the start end side of the upper sorting conveyance path 5, each traveling carriage 1
By transferring the transported object W on the sorting slat conveyor 14 of FIG. 1, the transported object W can be transported along the upper sorting transport path 5. Immediately before each traveling carriage 1 for transporting the transported object W arrives at the preset sorting position 18, the primary coil of the conveyor driving linear motor 20 arranged at the sorting position 18 is set. When the traveling carriage 1 arrives at the sorting position 18 by energizing in accordance with the required conveyor driving direction (to the right or to the left), the lower portion of the sorting slat conveyor 14 of the carriage 1 is moved downward. The energized primary coil 21 applies a propulsive force in a predetermined direction to the slat plate (secondary conductor plate) 17 in the side return path by a magnetic action.

As a result, the chain of the slat conveyor 14 is inserted through the slat plate (secondary conductor plate) 17 facing the primary coil 21.
Each slat plate 17 is rotated by a rotational force acting in a predetermined direction on 16 so that the transported object W mounted on the conveyor 14 is moved in a predetermined direction (rightward or leftward) at a predetermined sorting position 18. ), And is discharged onto the chute 19.

It should be noted that the traveling vehicle 1 can be circulated on a horizontal plane, and can also be run on a three-dimensional route at a place other than the sorting route. Further, the propulsion means of the traveling vehicle 1 is not limited to the linear motor system shown in the embodiment. Further, the sorting slat conveyor may be configured to be capable of sorting only in one of the left and right directions.

(Effects of the Invention) As described above, according to the sorting conveyance device of the present invention, the motor (primary coil for linear motor) that drives the sorting conveyor mounted on the traveling carriage is not on the traveling carriage but on the ground side. Since it is arranged at each sorting position on the trolley travel route side, the trolley can be made smaller and lighter and less costly than when the conveyor drive motor installed on each trolley is energized from the ground side. It is possible to reduce significantly.

Moreover, a slat conveyor is used as the sorting conveyor, the slat plate of the slat conveyor is configured as a secondary conductor plate of the linear motor, and the slat plate is directly propelled by the primary coil for the linear motor arranged on the ground side. Therefore, for example, compared with a configuration in which a driven body propelled by a primary coil for a linear motor on the ground side is provided and the movement of this driven body is transmitted to a sorting conveyor,
The efficiency is high, the structure is very simple, and there is almost no risk of failure.

Further, when a belt conveyor is used as the sorting conveyor and the flexible belt of this belt conveyor is configured as the secondary conductor of the linear motor, the conveyor belt portion facing the primary coil of the linear motor is In order to maintain a minute gap between the coil with high accuracy,
The aluminum (or copper) layer, which is not only very difficult to slidably support, but also the metal layer that must be laminated to the belt body must be very thin, the preferred secondary conductor structure Although it is difficult to adopt a two-layer structure of a steel plate and an iron layer, when the slat plate of the slat conveyor is configured as the secondary conductor plate of the linear motor as in the present invention, a conveyor chain that supports the slat plate is used. Since it is usual to guide with a guide rail, just adopt this guide means in the return path,
Not only is it possible to maintain a precise gap between each slat plate (secondary conductor plate) and the primary coil for the linear motor on the ground side with high precision, but each slat plate is supported independently. Therefore, there is no problem in constructing the slat plate into a preferable structure as the secondary conductor plate for a linear motor as described above, and it is possible to construct a linear motor for driving a conveyor easily and easily and with high efficiency. Can be done.
