Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a branching device for a conveyor.

[0002]

[Prior art]

 As a branching device in a conventional transport line, there are an extrusion type in which a side surface of a transported cargo is pushed out by an pushing device, a floating type in which a transported cargo is lifted up, and a branching type in which a guide rod is put in a branching path for sorting.

[0003]

[Problems to be solved by the device]

 However, since these conventional branching devices are designed to branch the transported cargo from one transport line only in the right-angled direction, the conventional branching devices are used to adjoin the adjacent branching devices. If the cargo to be transported is to be arbitrarily branched (for example, traversing multiple transport lines or also in the reciprocating direction) between multiple transport lines, transport from the transport lines At least two branching devices had to be installed on each transport line for the removal of cargo and the transport of cargo onto the transport line.

Moreover, when another transportation line exists between the two transportation lines where the transportation cargo is going to be branched, only the specific transportation cargo is surely transferred via the other intermediate transportation line. It was necessary to control each branching device accurately and intricately so that it could be branched into two.

The present invention has been made in view of the above-mentioned problems, and it is possible to arbitrarily branch a cargo to be carried by installing one branching device for each carrying line, and to branch the cargo. The purpose is to simplify the control of the entire device.

[0006]

In order to achieve the above-mentioned object, a branching device of the present invention is a drive type stretched on a support base that is rotatable around an axis line in a direction vertical to a transfer line. This is a conveyor branching device that consists of a branching roller and a crossing roller arranged adjacent to each branching roller between a plurality of conveying lines, and the support base supporting the crossing roller is vertically movable. Therefore, the side surface of the support base of the transfer roller is used as a stopper for the transported cargo branched from one transport line to another when it is raised.

[0007]

[Action]

 When it is attempted to branch the transported cargo from the first transport line to the adjacent second transport line, the transport direction of the branch rollers of the first transport line is transported by the rotation of the support table of the branch rollers. The support for the transition rollers located between the second and third transfer lines is raised while being oriented substantially at right angles to the line. When the cargo transported along the first transportation line is sent out onto the branch roller of the first transportation line, the branch roller is driven, and the transportation cargo moves in the direction perpendicular to the first transportation line. And is fed to the branch roller of the second transport line via the transition roller. At this time, the transported cargo comes into contact with the support base of the transfer roller which is already in the raised position and is stopped on the second transportation line. Next, by driving the branch roller of the second transport line, the transported cargo is transported along the second transport line.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows first, second and third conveying lines (1) (2) (3) consisting of roller conveyors. The transport lines (1), (2) and (3) are substantially parallel to each other and provided with branch rollers (4), (5) and (6) at the branching position. Each branch roller (4) (5) (6) can be driven by a motor and, as shown in FIG. 2, a support base (7) (which supports each branch roller (4) (5) (6)). The drive devices (10), (11) and (12) can rotate the drive shafts (8) and (9) about the vertical axis with respect to the transfer lines (1), (2) and (3). As a result, the branch rollers (4), (5) and (6) are moved to the positions where the conveyed cargoes are transferred along the respective conveyance lines (1), (2) and (3), and the respective conveyance lines (1) (2) ( It is possible to selectively set the position for transporting the cargo in a direction substantially perpendicular to 3).

In the case shown, only the branching roller (4) of the first transfer line (1) is in a position where the transferred cargo can be transferred in a direction substantially perpendicular to the transfer line (1). Crossover rollers (13) and (14) are provided between the conveying lines (1), (2) and (3) corresponding to the branch rollers (4) (5) (6).

As shown in FIG. 2, the support bases (15) and (16) for supporting the transfer rollers (13) and (14) can be moved up and down by, for example, piston-cylinder units (17) and (18). . As a result, the transition rollers (13) and (14) are at the same descending position as the conveying lines (1) (2) (3) or the branch rollers (4) (5) (6), and from there. The elevated position can be selectively taken.

In the illustrated case, the transition roller (13) between the first and second transfer lines (1) and (2) is in the lowered position, and the transfer roller (13) between the second and third transfer lines (2) and (3) is in the lowered position. The transition roller (14) is in the raised position. In this case, the transition rollers (13) and (14) are non-driving type, but may be configured to be drivable if necessary. Further, the outermost transportation lines (transportation lines (1) and (3) in the figure) have stoppers (19) (20) for the transported cargo on the outer wall at the branch position. .

Next, a process for branching a conveyed cargo using the branching device composed of the branching rollers (1) (2) (3) and the transfer rollers (13) (14) will be described with reference to FIGS. To do. When attempting to branch the transported cargo (A) from the first transport line (1) to the adjacent second transport line (2), the branch roller (4) of the first transport line (1) By rotating the support base (7) of the apparatus using the drive unit (10), the feeding direction of the branch roller (4) is oriented substantially at right angles to the first transfer line (1), and The support stand (16) of the transfer roller (14) located between the third transfer line (2) and the third transfer line (3) is lifted by the piston-cylinder unit (18).

When the conveyed cargo (A) conveyed along the first conveyor line (1) is sent out onto the branch roller (4), the branched roller (4) is rotationally driven to convey the conveyed cargo. (A) is sent out from the first transfer line (1) to the branch roller (15) of the second transfer line (2) through the cross roller (13) in a direction substantially at right angles.

At this time, the transported cargo (A) comes into contact with the side surface of the support base (16) of the transfer roller (14) already in the raised position and is stopped on the second transport line (2). Next, when the branch roller (5) of the second transport line (2) is rotationally driven, the transported cargo (A) is transported along the second transport line (2).

Further, in the case where the carrier cargo (A) is to be branched from the first carrier line (1) to the third carrier line (3), the second and third carrier lines (2) ( The support base (16) of the transition roller (14) between 3) is also stopped at the lowered position.

The cargo (A) similarly branched from the first transfer line (1) toward the third transfer line (3) is transferred to the stopper (20) of the third transfer line (3). It comes into contact and stops, and is then transported along the third transport line (3) by the rotational drive of the branch roller (6).

The branching process from the third transfer line (3) to the first or second transfer line (1) (2), and the first or third transfer from the second transfer line (2) The branching process to the lines (1) and (3) and the branching process when there are four or more transfer lines are performed in exactly the same manner as described above.

[0018]

[Effect of device]

 The present invention has the following effects. (a) By simply equipping each transfer line with one branching device, the branching of the cargo transported between each transfer line can be made to traverse multiple transfer lines or in the reciprocating direction. It can be realized at will.

(B) Since each of the transfer rollers is also used as a stopper for the conveyed cargo, the configuration of the entire branching device becomes simpler.

(C) The simplification of the branching device as described above and the fact that only one branching device is required for each transport line further facilitates the control of the entire branching device.
