Hereinafter, the turntable of the present invention, a turn conveyor using the turntable, and a tray for the conveyor will be described in detail with reference to FIGS.
The shape of the “conveyed object” conveyed using the turntable and a turn conveyor using the turntable is not particularly limited as long as it is a solid object placed on the conveyor. In particular, the turntable and the turn conveyor using the turntable are suitable for transporting a transported object whose cylindrical mounting surface is easy to roll or slide due to a curved surface or the like.
The “cylindrical shape” refers to a cylindrical shape and a shape similar thereto. For example, in addition to the cylindrical shape itself, a shape having one or more protrusions and depressions, a cylindrical shape having a taper or a bulge, and the like can be given. Further, a cylindrical shape and a shape similar thereto may be included.
The kind of the “conveyor” used in the turntable and the turn conveyor using the turntable is not particularly limited, and examples thereof include a belt conveyor and a vibrating conveyor. In addition, the “conveying unit 111” refers to a part that conveys the conveyed product on the conveyor. For example, in the case of the belt conveyor 11 illustrated in FIG. The surface is a transport unit.

As illustrated in FIGS. 1 and 2, the “conveyor guide 113” is a guide that is continuously provided on the side of the conveyance unit 111 and biases the conveyed product 3 toward the wall 112. By biasing the conveyed product 3 to the wall 112, it is possible to prevent the direction of the conveyed product 3 from changing when the conveyed product 3 is being conveyed. This guide may be wall-shaped or may be a collection of columnar bodies that are spaced apart. The conveyor guide 113 only needs to be able to move the interval between the conveyor wall and the wall so that the conveyed product can be moved. The conveyor guide 113 may be fixed to a certain width or set to an arbitrary width according to the type of the conveyed item. Also good.
Further, the conveyor guide 113 preferably has its one end extended to above the turntable 12 as illustrated in FIG. This is because by extending to the upper side of the turntable 12, it can be guided so that the direction does not change when the conveyed product 3 moves between the conveyor 110 and the conical part 121. Moreover, although the length to extend | stretch can be selected arbitrarily, extending | stretching can be mentioned until the end of the conveyor guide 113 is located above the outer periphery of the cylindrical part 121, for example.

The “conical part 121” is a substantially conical turntable having an inclined surface such as a taper or the like on the conveying surface, and is mainly placed on the peripheral edge of the inclined surface and rotated around the central axis of the cone. By doing so, it is used to change the transport direction while keeping the direction of the transported object constant with respect to the transport direction. Further, the shape of the conical portion 121 is not limited as long as the conveying surface is provided with an inclined surface such as a taper. As illustrated in FIG. An arbitrary shape such as can be selected.
By placing the conveyed product on such an inclined surface portion of the conical portion 121, the conveyed product tends to move closer to the outer peripheral side and rotates while contacting the table guide 123 provided along the circumference of the conical portion 121. The direction of the object can be easily kept constant with respect to the transport direction. Further, the inclination angle of the inclined surface of the conical portion can be arbitrarily selected according to the ease of movement of the conveyed product.
Further, as illustrated in FIGS. 2 and 3, the conical portion 121 is preferably located above one end side of the conveying portion 111 of the conveyor 11. By providing a gap above and below the conical part 121 so as not to contact the transport part 111, it is possible to suppress an increase in the load for the conical part 121 to operate in contact with the transport part 111. The rotation can be stabilized, and the direction of the conveyed product can be prevented from being changed or caught. Even if a gap is provided, the frictional part 122 extending from the conical part 121 is in contact with the conveying part 111, so that the step between the turntable 12 itself and the conveying part 111 is only the thickness of the frictional part 122, and the conveyed object Can be suppressed. The size of the gap to be provided may be any size as long as the conical part 121 does not come into contact with the transport unit 111 and can be arbitrarily selected.

The “friction part 122” is a layer for appropriately adjusting the friction between the conical part 121 and the conveyed object in order to change the direction of the conveyed object by the rotation of the conical part 121. The material of the friction part 122 can be arbitrarily selected. For example, when the conveyed product is made of ceramic or the like, materials such as soft synthetic resin and elastomer (including rubber) are preferable. The friction part 122 may be made of the same material as the conical part 121. Furthermore, the friction part 122 and the conical part 121 may be integrally formed.
As illustrated in FIGS. 2 and 3, it is preferable that a part of the friction portion 122 extends from the peripheral edge of the conical portion 121. Moreover, it is preferable that the periphery of the friction part 122 is brought into contact with the conveyance surface of the conveyance part 111. By extending the friction part 122 from the peripheral edge of the conical part 121, the lower end of the friction part 122 can be made substantially the same height as the lower end of the conical part 121 or a lower position. This is because the level difference between the two can be eliminated, and the conveyed product can be easily conveyed between these without being caught.

  The “table guide 123” is a guide provided to guide the transported object placed on the conical portion 121 to the second conveyor. Similar to the conveyor guide 113, the guide may be a wall shape or may be a collection of columnar bodies arranged apart from each other. There is no particular limitation as long as it can be guided to the conveyor. Furthermore, the table guide 123 is provided along the circumference of the conical part 121, but the angle may be at least a range used for conveyance.

  As illustrated in FIGS. 4 and 5, the present conveyor tray includes a wall surface portion 21 provided along the traveling direction of the conveyor. Moreover, you may provide the bottom part 22 which connects between the wall surface parts 21. FIG. The “wall surface portion 21” has a tapered shape in which the interval is narrowed downward, and the upper end of one end locked to the end of the wall portion 112 of the conveyor is extended to the conveyor side. It has. With this shape, when the conveyor tray 2 is provided so as to be closer to the conveyor 11, the height of the bottom 22 on the conveyor 11 side is increased. Further, when the conveyor tray 2 is provided so as to be separated from the conveyor 11 side, the height of the bottom portion 22 on the conveyor 11 side is lowered. This makes it possible to easily adjust the bottom 22 and the height of the conveyor belt that is the transport unit 111 of the belt conveyor 11.
