As described above, the conveyed product sorting apparatus 5 is unitized by attaching an attachment member to the skeleton member 40. And the branch conveyor apparatus 1 is completed by incorporating in the main conveyor apparatus 2 grade | etc.,.
Hereinafter, the assembly procedure of the branch conveyor apparatus 1 will be described.
The branch conveyor device 1 is completed by combining the main conveyor device 2 as shown in FIG. 5, the sub-conveyor device 3 as shown in FIG. 6, and the conveyed product sorting device 5 as shown in FIG.
In the assembly, first, the main conveyor device 2 and the sub-conveyor device 3 are combined. That is, the right side frame 30 of the sub-conveyor device 3 is aligned with the left side frame 7 of the main conveyor device 2, screws are inserted into the mounting holes 35 and 22, and the sub-conveyor device 3 is attached to the main conveyor device 2. .

Then, the support member 42 of the conveyed product sorting device 5 is inserted into the notch 18 provided in a part of the right side frame 6 of the main conveyor device 2. In other words, the support member 42 of the conveyed product sorting device 5 is disposed between the auxiliary rollers 36 and 37. In this state, the main frame portion 41 of the conveyed product sorting device 5 is disposed in the groove 17 of the right side frame 6 of the main conveyor device 2, and the main frame portion 41 is fixed to the right side frame 6 with screws (not shown). More specifically, the back side of the main frame portion 41 is brought into surface contact with the groove 17 side of the vertical wall portion 13 of the right side frame 6 of the main conveyor device 2, and both are fixed with screws.
Further, the front end of the support member 42 (the outer surface of the back wall 70) is supported by the left side frame 7 of the main conveyor device 2. More specifically, a screw 25 (FIG. 8) is inserted between a mounting hole (not shown) provided in the back wall 70 of the support member 42 and a screw-fastening hole 21 of the left side frame 7. Join.
The branch conveyor 1 is completed through the above steps.

Next, the function of the branch conveyor 1 will be described.
The branch conveyor 1 of this embodiment can also convey a conveyed product linearly along the main conveyor device 2, and can also change a conveyance direction of a conveyed product and can discharge a conveyed product to the sub-conveyor apparatus 3 side. .
That is, when the conveyed product is conveyed linearly along the main conveyor device 2, the guide member 60 is in a posture parallel to the right side frame 6 of the main conveyor device 2 as shown in FIG. 60 is escaped to the outside of the conveying surface of the main conveyor device 2.
And the main conveyor apparatus 2 is driven and the standard roller 10 is rotated. As a result, the conveyed product advances in the longitudinal direction of the main conveyor device 2 by the rotational force of the standard roller 10.

On the other hand, when changing the conveyance direction of the conveyed product and discharging the conveyed product to the sub-conveyor device 3 side, the geared motor 55 is driven to rotate the driving pulley 56 and the belt 58 is caused to travel so that the top member 61 is moved linearly. As a result, the guide member 60 swings on the main conveyor device 2, and the guide member 60 protrudes on the conveyance surface of the main conveyor device 2. That is, as shown in FIG. 2, the guide member 60 obliquely crosses the conveyance surface of the main conveyor device 2, and the upstream end of the left side frame 31 of the sub-conveyor device 3 and the tip of the guide member 60 are connected.
In this state, both the main conveyor device 2 and the sub-conveyor device 3 are driven, and the standard roller 10 and the roller 32 are rotated. The conveyed product is picked up by the main conveyor device 2 but immediately collides with the guide member 60 and advances in an oblique direction along the guide member 60. Eventually, a part thereof reaches the sub-conveyor device 3 and is placed on the roller 32 of the sub-conveyor device 3. Thereafter, the conveyed product travels on the sub-conveyor device 3 according to the rotation of the rollers 32 of the sub-conveyor device 3.

In the above-described embodiment, the roller is used as the conveyance body, but a belt or a roller may be used instead of the roller 10.
Further, in the embodiment described above, the cutout portion 18 is provided in a part of the right side frame 6, but as shown in FIG. 9, the right side frame 6 is divided into a plurality of portions to form a missing portion 27. The support member 42 may be inserted into the missing portion 27.

In the embodiment described above, the auxiliary rollers 36 and 37 are provided between the two standard rollers 10 in the vicinity of the notch 18. The auxiliary rollers 36 and 37 are provided to prevent the conveyed product from falling between the standard roller 10 and the support member 42. That is, the auxiliary rollers 36 and 37 are used as members for filling the gap between the standard roller 10 and the support member 42.
In the present embodiment, the auxiliary rollers 36 and 37 are idle rollers having a small diameter, but may be simple bars. That is, instead of the auxiliary rollers 36 and 37, a round bar, a steel strip or the like can be adopted. Further, the auxiliary rollers 36 and 37 can be omitted.
