Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention is to carry out articles loaded on a trolley traveling on a fixed route in the lateral direction when passing through a predetermined sorting position. The present invention relates to a sorting transport device that can be used.

(Problems to be Solved by the Related Art and Invention) In this type of sorting transport device, there are
It is necessary to have a conveyor for discharging the load in the lateral direction and a driving means for the conveyor. If a motor is mounted on the carriage as the conveyor driving means, power supply and control signal transfer equipment for the motor on the traveling carriage is required, resulting in high cost. Therefore, it was considered that a roller conveyor was used as the conveyor, and each roller of this roller conveyor was used as the secondary conductor of the linear motor to directly drive the conveyor roller by the main body of the linear motor on the ground side. Since it was thought to drive the rollers of the linear motor by a linear motor, a linear motor main body with the same length as the entire length of the roller conveyor in the transport direction is required. Since the linear motor main body corresponding to the length must be manufactured, a problem that a considerable amount of cost still arises occurred.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides
A roller conveyor that conveys a load is arranged on the carriage that travels on a fixed route in the left and right lateral directions that are orthogonal to the traveling direction, and each roller of this roller conveyor is linked and linked to each other. At the sorting position, a linear motor main body that is close to the central portion of the roller conveyor in the conveying direction from below is provided, and only a plurality of rollers in the central portion of the roller conveyor in the conveying direction are linearly arranged. The present invention proposes a sorting conveyance device that can be rotationally driven by a motor body.

(Operation of the Invention) The trolley on which the sorted articles are loaded on the roller conveyor travels on the certain route.
Any conventionally known means such as a linear motor on the ground or a trolley and a rotary motor mounted on the trolley may be used.
However, when the traveling carriage reaches a predetermined sorting position, when the linear motor body located at the sorting position is energized, among the rollers in the roller conveyor on the carriage, the central portion closely facing the linear motor body. Only a plurality of rollers in the area are rotationally driven in a predetermined direction by the magnetic action between the rollers and the linear motor body. The other roller rotates in conjunction with the roller driven by the linear motor body. Therefore, the load on the roller conveyor of the truck is accompanied by the rotation of each roller.
It is carried out in either the left or right direction, which is orthogonal to the traveling direction of the carriage, and predetermined sorting is performed.

Since the load to be carried out is usually placed in the central area of the roller conveyor, the rollers directly driven by the linear motor body are only the plural rollers in the central area of the roller conveyor. Also, the load is surely given an initial speed by the plurality of rollers and is started. Since the load once started can be conveyed with a relatively small propulsive force, it can be reliably delivered by the roller conveyor in the end area of the roller conveyor that rotates in conjunction with the rollers in the central area.

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

In FIG. 1, reference numeral 1 denotes a trolley which travels on a fixed path, and is provided with a roller conveyor 4 for carrying out a load 2 in left and right lateral directions orthogonal to the trolley traveling direction 3. Each trolley 1 has a pair of left and right spherical couplers 5 projecting from one end in the traveling direction, and a pair of left and right bowl-shaped couplers 6 projecting from the other end in the traveling direction. Between adjacent carts 1, a pair of left and right bowl-shaped couplers 6 of the other truck 1 are fitted to a pair of left and right spherical couplers 5 of one truck 1. However, in the horizontal curve path portion, a pair of left and right spherical connectors 5 are provided.
Among the bowl-shaped coupled tools 6, only the spherical coupling tool 5 and the bowl-shaped coupled tool 6 located inside fit with each other, and the spherical coupling tool 5 and the bowl-shaped coupled tool 6 located outside each other Separate.

When the curve path portion does not have the vertical curve path portion but only the horizontal curve path portion, a cylindrical connecting tool is used instead of the spherical connecting tool 5, and the bowl-shaped connected tool 6 is used instead. A gutter-shaped coupling tool may be used. Further, each carriage 1 may be connected by a free connecting means capable of transmitting a tensile force as in a general sorting conveying device.

Sorting chutes 7a, 7b are provided at sorting positions in the travel route of the trolley 1 for receiving the load 2 discharged laterally from the roller conveyor 4 on the trolley 1.

As shown in FIGS. 2 to 4, the carriage 1 includes a supporting horizontal shaft wheel 9 and a steady rest vertical shaft roller 10 which are fitted to a pair of left and right guide rails 8a, 8b having a U-shaped cross section. Are pivotally supported near the four corners via brackets 11. or,
The roller conveyor 4 includes a large number of rollers 12a, 12b axially supported at regular intervals and a transmission rope for interlocking and rotating all the rollers 12a, 12b in the same direction.
It is composed of 13 and. In the illustrated example, the adjacent rollers are linked to each other by the transmission rope 13 alternately to the left and right,
The method of hanging the transmission rope is not limited to this. Of course,
Each roller may be interlockingly connected by interlocking means other than the transmission rope. Further, in the illustrated example, both end angular shaft portions of the support shaft 16 that rotatably supports the rollers 12a and 12b cannot rotate and move axially in the notch recesses 15 formed in the front and rear side plates 14 of the bogie 1. Although fitted in the state, each roller 12a, 12b
The shaft support structure of is not limited to this. Reference numeral 17 denotes a cover plate, which is attached to the front and rear both side plates 14 so as to cover the notched recessed portion 15 and has an opening 18 through which the tops of the rollers 12a and 12b are exposed.

The bottom plate 19 of the trolley 1 is provided with an opening 20 below the plurality of rollers (5 in the illustrated example) of the rollers 12a, 12b of the roller conveyor 4 in the central area in the transport direction (5 in the illustrated example). The front and rear side plates 14 are also notched so that the central portion of the lower side connecting to the opening 20 exposes the lower top portion of the roller 12a when viewed from the front and rear. Further, the bogie frame of the bottom plate 19 and the like is made of aluminum, and iron strips 21a and 21b are provided on the bottom plate 19 on both the left and right sides of the opening 20 in parallel with the traveling direction of the bogie, and a linear motor for traveling. Secondary conductor portions 22a and 22b are formed.

Among the rollers 12a, 12b of the roller conveyor 4, at least the plurality of rollers 12a facing the opening 20 are
As is well known in the art, an iron cylindrical body and an aluminum coating layer that covers the cylindrical body are used so that the peripheral wall serves as the secondary conductor of the linear motor.

On the other hand, on the traveling route side (ground side) of the carriage 1, the traveling linear motor main bodies 23a, 23b are spaced at appropriate intervals so that the secondary conductor portions 22a, 22b of the traveling linear motor of the carriage 1 are close to each other. And the sorting chute shown in FIG.
At each sorting position where 7a, 7b are provided, a conveyor driving linear motor main body 24 is provided near the lower top of the roller 12a through the opening 20. The traveling linear motor main bodies 23a, 23b give thrust to the truck 1 in the traveling direction by magnetic action between the traveling linear motor main body 23a, 23b and the secondary conductor portions 22a, 22b of the traveling linear motor on the truck 1 side. The driving linear motor main body 24 is a roller that is approached through the opening 20 when the trolley 1 passes on it.
By the magnetic action between the peripheral wall of 12a (secondary conductor portion for linear motor), a rotational force in the same direction is applied to each roller 12a.

In the sorting transport device configured as described above, by energizing and energizing each traveling linear motor main body 23a, 23b, each traveling linear motor main body 23a, 23b
The trolley 1 in which the secondary conductors 22a, 22b are close to each other has the traveling linear motor main bodies 23a, 23b and the trolley-side secondary conductors 22a, 2b.
Due to the magnetic action between 2b and the vehicle, the vehicle travels at a predetermined speed by receiving thrust in a predetermined direction. Then, the trolley 1 travels through each sorting position, but from the time just before the particular trolley 1 passes through each sorting position until the end of passing.
By energizing and energizing the conveyor driving linear motor main body 24 disposed at the sorting position, when the roller 12a of the roller conveyor 4 passes directly above the linear motor main body 24, the linear motor main body 24 is separated from the linear motor main body 24. Due to the magnetic action of, the roller 12a is rotationally driven in a predetermined direction. The rotation of the roller 12a is also transmitted via the transmission rope 13 to the other rollers 12b not facing the linear motor body 24 (four rollers in each of the left and right in the illustrated example, a total of eight rollers), and all the rollers of the roller conveyor 4 are connected. 12a and 12b rotate. Therefore, the load 2 placed on the roller conveyor 4 is conveyed in a predetermined direction to the left or right according to the rotation of the rollers 12a and 12b, and is carried out onto the chute 7a or 7b at a predetermined sorting position. Be sorted.

The traveling drive means of the carriage 1 is not limited to the linear motor system shown in the embodiment.

(Effects of the Invention) As described above, according to the sorting conveyance device of the present invention, the roller conveyor on the carriage is driven by the linear motor main body on the ground side. In comparison, not only can the entire trolley be made lightweight and small, but there is no need to intervene equipment for power supply and control signal exchange between the trolley and the ground side to drive the roller conveyor, and thus the device The whole can be constructed very inexpensively.

Further, in the present invention, the linear motor main body on the ground side for driving the roller conveyor on the carriage can be configured to have a constant length shorter than the length of the roller conveyor in the conveying direction. Can be configured to have any length in the carrying direction depending on the size of the article to be handled. Therefore, as compared with the case where the length of the roller conveyor in the conveying direction and the length of the linear motor main body are equal, the sorting conveying device according to the size of the articles to be handled can be constructed at low cost.
