Description

  The present invention relates to a transport device, and more particularly, to a transport device having a transfer endless loop path and a sorting endless loop path for transporting a transport object such as a large envelope for home delivery.

In recent years, documents, magazines, books, CD cases, etc. are transported by courier or mail.
In this transportation, documents, magazines, and the like are stored in a large envelope for delivery to home or mail made of vinyl or paper, or in a case such as cardboard or cardboard. Also, magazines and the like are sometimes not transported in envelopes or cases, but are transported only in a band or as they are.
The large envelopes and cases (including postcards and small envelopes) described above are classified by a dedicated transport machine.

(Conventional technology)
Next, a conventional transporter (a transporter for postcards and small envelopes) will be described with reference to the drawings.
8A and 8B are schematic views of a conventional transporter, where FIG. 8A is a plan view and FIG. 8B is a front view.
FIG. 9 shows a schematic enlarged view of the E portion of FIG.
Further, FIG. 10 shows a schematic enlarged view seen from F of FIG.

  As shown in FIGS. 9 to 10, a conventional transport machine 100 includes a housing 110, a guide rail 150 provided in the housing 110 and formed in an endless loop shape having a straight portion and a curved portion, It comprises a plurality of transport carts 106 that are supported by guide rails 150 and circulate along an endless loop path, and a transport box 120 that is suspended by the transport cart 106.

(Transport cart)
The transport carriage 106 is rotatably connected via a joint 161 inserted from the vertical direction (see FIG. 9). The transport carriage 106 and the joint 161 form a chain conveyor 160. The conveyor cart 106 can be moved by applying a sprocket (not shown) to the chain conveyor 160 and rotating it.

(Transport box)
The transport box 120 has a substantially rectangular box shape. The transfer box 120 has a transfer port (not shown) through which the transfer object 110 is thrown on the side surface on the outer side of the guide rail 150, and discharges the transfer object 101 at the bottom. A rotating bottom cover (not shown) is provided.
In addition, the transport box 120 has no side plate on the inward side facing the transfer port. Instead of this side plate, a receiving side plate (not shown) is fixed at a position corresponding to the transfer portion 13 of the housing 110. If it does in this way, the conveyance target object 101 which moved into the conveyance box 120 at high speed through the transfer port from the transfer part 13 will collide with a receiving side plate, will fall, and will be accommodated in the conveyance box 120. That is, since the side plate receives the impact of the conveyance target object 101 thrown into the conveyance box 120 at high speed, the mechanical strength of the conveyance box 120, the conveyance carriage 106, etc. can be reduced.

  In addition, every other transport box 120 is suspended from the connected transport cart 106 (see FIG. 10). Here, the transport box 120 is supported so that the center of gravity of the transport box 120 is located almost directly below the guide rail 150 when viewed from above. That is, when viewed from above, the transport box 120 has an outer half located on the outer side of the guide rail 150 and an inner half located on the inner side of the guide rail 150 (see FIG. 9).

(Casing)
The casing 110 includes a plurality of sorting unit casings 109 and a supply unit casing 12. (See Figure 8)
The sorting unit housing 109 includes a plurality of stacking units 109 a that stack the objects to be transported 101 discharged from the transport box 120.
The supply unit housing 12 includes a transfer unit 13 that supplies the conveyance object 101 to the conveyance box 120 by the belt 14.
In general, the stacking unit 109a and the transfer unit 13 are disposed in a straight conveyance portion of the conveyance box 120.

Next, the operation of the conveyor 100 will be described.
The objects to be conveyed 101 (postal items, mainly postcards, small envelopes, etc.) are individually conveyed one by one from the supply unit housing 12 to the transfer unit 13 by the belt 14. Subsequently, the transfer object 101 is transferred (thrown) to a predetermined transfer box 120 by the transfer unit 13.

The transport box 120 is transported at a constant speed by driving means (not shown) that moves the chain conveyor 160. Here, as shown in FIG. 9, the transport machine 100 has a constant interval between the transport boxes 120 (interval L3 = interval L4). For this reason, the space | interval of the conveyance box 120 is set to the space | interval L4 which the inner half of the adjacent conveyance box 120 does not interfere seeing from the upper surface in the curved part of the guide rail 50. FIG.
However, although the minimum interval L4 at which the transport boxes 120 do not interfere with each other is set in the curved portion, the interval L3 between the transport boxes 120 includes a large gap Δ in the straight portion. Therefore, the mounting efficiency of the transport box 120 in the straight portion is deteriorated, and the transport density is sparse. In particular, the larger the conveyance object, the larger the gap Δ. For the above reason, the conveyance machine has a reduced processing capacity.

  The transport object 101 transported in the transport box 120 is discharged to a predetermined stacking unit 109a of the sorting housing 109 for each destination. That is, the transport device 100 can classify the transport target object 101 by destination while transporting the transport target object 101.

The transport machine 100 having the above configuration increases the number of processes by increasing the transport speed because the number of processes of the transport object 101 per unit time depends on the transport speed of the transport carriage 106 of the chain conveyor 160. be able to. However, when the transport device 100 increases the transport speed, the throwing operation and the discharge operation of the transport target object 101 performed on the transport box 120 during transport become unstable, and reliability in the processing operation of the transport target object 101 is increased. There was a disadvantage that it caused a decrease in the property.
In addition, when the transporting apparatus 100 stabilizes the processing of the throwing-in operation and the discharging operation of the transport object 101 by slowing the transport speed, the mounting efficiency of the transport box 120 in the straight portion is low, so that the unit time There was a drawback that the processing capacity of the transported product was reduced.

In order to solve the drawbacks of the transport device 100, Patent Document 1 discloses a technique of a transport distance variable transport device. This transfer machine is provided with a transfer interval variable mechanism that makes the interval of the transfer box variable at the boundary portion between the straight line portion and the curved portion of the endless loop path, thereby increasing the mounting density of the transfer box in the straight line portion. Conveying speed in is minimized. By doing in this way, the processing capacity of a conveyed product does not fall, and the transfer operation and discharge operation | movement of a conveyed product are stabilized.
JP 2003-237926 A (Claim 1, FIGS. 2, 5)

By the way, when the transport object is enlarged like a large envelope for home delivery, when the transport machine transfers the transport object from the transfer unit to the transfer transport box, the transport object depends on the size of the transport object. , Need long transfer time. The transfer time can be shortened by increasing the transfer speed of the transfer unit, but a predetermined maximum transfer speed is selected depending on the impact resistance of the object to be conveyed.
That is, since the transfer machine requires a long transfer time when the transfer object becomes large, it is necessary to increase the storage width of the storage port of the transfer box or to decrease the transfer speed of the transfer box. The ability will be reduced.

However, the transport machine 100 is configured to perform transfer and sorting of the transport target object 101 using one endless loop path, and when the transport target object 103 is enlarged, a long transfer time is required. . For this reason, it is necessary for the transporter 100 to widen the storage width of the storage chamber of the transport box 120 or to slow the transport speed of the transport box 120, thereby reducing the processing capacity and stabilizing the transfer operation. There was a problem that could not.
In addition, the conveyance distance variable type conveyance machine of Patent Document 1 has a complicated structure and control, and has a problem that, for example, the manufacturing cost cannot be reduced.

  In order to solve the above-mentioned problem, the present invention has an endless loop path for transfer and an endless loop path for sorting, so that even when the transport object is enlarged, the processing capacity of the transport object is increased. An object is to provide a transporter capable of improving and stabilizing the transfer operation.

For the transfer The transport box and the sorting transport box have one or more storage chambers, and the storage width of the transfer transport box in the storage direction with respect to the traveling direction is the storage width of the sorting transport box in the storage direction with respect to the traveling direction. The number of transfer guide rails n (n is a natural number) is 2 or more, the section guide rails are n stages, the delivery means is n stages, and the delivery means is linear delivery In the section, the transfer object is transferred.

If it does in this way, said conveyance machine does not need to receive the restriction | limiting resulting from the conventional fundamental structure of transferring and classifying a conveyance target object using one endless loop-shaped path | route. The transfer machine can freely combine one or two or more staged endless loop paths for transfer and endless loop paths for sorting, and is suitable for transfer of objects to be transferred. It becomes possible to use a transfer box for transfer, and even when the transfer object is enlarged, the processing capacity of the transfer object can be improved and the transfer operation can be stabilized.

Moreover, said conveyance machine can utilize an installation area effectively, when the guide rail for a division | segmentation is multistaged. Note that n is a natural number of 2 or more.

Further, in the above-described transporting machine, the transfer transport box and the sorting transport box have one or more storage chambers, and the storage width of the transfer transport box in the storage chamber with respect to the traveling direction is set as the sorting width. It is set as the structure made wider than the accommodation width | variety with respect to the advancing direction in the storage chamber of the conveyance box for a vehicle.
If it does in this way, the conveyance machine can transfer (throw in) a conveyance target object to the conveyance box for transfer reliably by widening the storage width of the storage chamber of the conveyance box for transfer.

Further, the transfer device is configured such that the transfer means transfers the transfer object while the transfer transfer box and the sorting transfer box are running side by side.
In this way, the relative speed of the transfer transport box and the sorting transport box that move at high speed becomes zero and becomes relatively stationary. Therefore, the delivery means can easily and reliably deliver the transport object. It can be carried out.

Further, in the transport machine, the transfer unit transfers the transport target object by dropping the transport target object transferred to the transfer transport box into the sorting transport box. It is as.
If it does in this way, the conveyance machine can simplify the delivery operation | movement of a conveyance target object, and can improve the reliability of delivery. In addition, the manufacturing cost of the conveyor is reduced.
