Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sorting device for single-quality items that does not damage the sorted items, has low noise, and has improved sorting ability.

[Conventional technology and its problems]

Conventionally, devices for sorting items such as parcels and letters by their destination and other information have been equipped with an endless conveyor line.
A supply line and a sorting line 1271 are provided at M locations on this conveyance line, and a large number of tray carts are connected to a chain conveyor and run on the line. Therefore, the driving of the chain conveyor generates a lot of noise, and the structure is complicated.

For this reason, a method has been used in which the tray truck is driven by a linear motor. However, when a large number of tray carts are arranged in succession and circulated along an endless conveyance line, a curved portion is required in the rotating portion that changes direction.

Further, since the conveyance line is arranged in an endless plane and a large number of sorting chutes are provided outside the conveyance line to sort the articles, a large space is required in terms of plane. There has been a desire for a device in which the conveyance line is arranged three-dimensionally in order to reduce the space required. However, no conventional device has been able to achieve this. Furthermore, as the number of sorted articles increases, there is a demand for improved sorting capacity, and in order to meet this demand, there are methods of increasing the traveling speed of sorting tray carts and methods of increasing the number of sorting devices.

However, the former method of increasing the traveling speed of the tray truck has drawbacks such as increased noise and increased damage to the load during unloading. Moreover, the method of expanding the equipment of a single wheat farmer has drawbacks such as the need for additional space and the equipment cost being high.

In view of this, an object of the present invention is to improve the sorting capacity by only changing a part of the tray truck without adding any equipment.

[Means for solving problems]

A straight section of the running track is arranged above and below, and a plurality of sorting chutes are arranged so that loads can be loaded onto the pan of the running cart from both sides of the loop-shaped running track that is bent into a loop shape at both ends. On the road, each independently; two tilts! 11 It is possible to run a traveling trolley equipped with pans on both the left and right sides of the upper part. do.

〔Example〕

For the sake of perspective, the invention 1 will now be described with reference to the illustrated embodiment.

In the figure, reference numeral 1 denotes a loop-shaped running path, and this is a pedestal 1 on which the lower part of the running rail 1a is arranged at a required interval.

At a part of Y, 12, at the position where the articles to be sorted are transferred onto the pan of the traveling trolley, that is, at the intersection I of the traveling rail.
Two sets of transfer conveyors 41 and 42 are arranged on one side of the outbound path on a straight path with X in between. These transfer conveyors 41 and 42 are adjacent to one side on the outbound side, but because they are arranged sandwiching the intersection of the running rails, the transfer conveyors 41 and 42 are placed on either one of the pans on the running truck. , and are loaded onto the pans on the other side from the other transfer conveyor 42. This is because the traveling direction of the traveling trolley traveling at the position of the transfer conveyor 41 and the traveling trolley traveling at the position of the transferring conveyor 42 is changed on the curved line at the end IW, so they move from the same direction of the traveling f terrail. Even when loaded, the running direction of the traveling cart is different, so the cargo is loaded independently onto two pans adjacent to each other on the left and right. Both of these transfer conveyors 41 and 42 are one or more transfer conveyors 41.

The three carriages are connected so that they can swing, and all the carriages run at the same time. The running of this running trolley 3 is carried out by several linear motors 6 arranged at appropriate intervals on one of the running paths 1. A large number of moving carts are transported simultaneously.

Note that the running speed and braking of the traveling truck are controlled by this linear motor 6. In addition, in order to drive the traveling truck more efficiently with this linear motor 6, a third
As shown in the figure, linear motors 6 are disposed so as to face both sides of a reaction plate 32 that is vertically installed on the lower surface of the traveling truck 3, and these two linear motors 6 are arranged as a set.
A thrust is applied from both sides of this reaction plate 32 at the same time. Moreover, the linear motor 6 is fixed to the frame of the running path.

The traveling truck 3 is shown in detail in FIGS. 3 to 5. A platform 1X having a predetermined size is placed at the bottom of the main body 30 in the running direction of the trolley 30? I) The reaction plate 32 is vertically disposed in such a manner that the shaft 3 supported by the pan support bracket 30B is mounted on the upper part.
03 is provided with a hinge 30H, and the pan 31R is attached via this hinge 30H or directly to the shaft 30S.

311, which are swingable and tiltable and are adjacently provided on the left and right sides. These two pans 31R and 31L have a 7-shape or a flat V-shape so that articles can be reliably transferred onto each pan 31R131L. This bread 31R, 31
L is bent into an L shape to prevent the loads on the pans 31R and 31L from moving accidentally. A frame 33 is fixed to the lower end of the reaction plate 32, and a wheel 30W is arranged at the bottom of this frame so that it can run on the rail IR of the running route 1, and the entire load of the running bogie 3 is carried by this wheel 30W. Support and further frame 33
Two horizontal guide rollers 30G are provided at the front and rear end positions of the
The lower part of the reaction plate 32 is prevented from tilting in the left-right direction with respect to the running direction I, and the gap between the reaction plate 32 and the near motor 6 is kept constant. to be able to hold it. Further, the rail IR is provided with an upper rail IU, and a vertical guide roll 3 provided vertically on the frame.
0R is brought into contact with the lower surface of the upper rail IU to prevent the traveling truck from climbing up from the traveling path due to the thrust given by the linear motor 6 during running. Also two breads 31R

is provided on the main body 30.

Connecting bracket 37°3 to the front end of the main body 30 in the running direction
The upper guide roller 37G is rotatably supported on a connecting shaft 373 that extends vertically through the connecting bracket 37 and is a turnbuckle type connecting rod 3.
Lock the end of 8. The end of the connecting rod 38 and the connecting shaft 37S are engaged by a ball joint type, so that even if the adjacent front and rear traveling carts swing in different directions, the ball joint portion prevents the swinging. The traveling carts are connected to each other so that they can travel in rotation.

A tiltable pan provided on the upper part of the traveling cart 3 loads articles on the transfer conveyor 41, 42, and tilts at a fixed position on the sorting chute 2, so that articles can be loaded and unloaded quickly and reliably. However, this uses conventional equipment.

When sorting articles using the traveling trolley configured as described above, the traveling trolley is connected to the pans 31R and 31 as shown by the solid line in FIG.
L is set in a loadable state and driven on a running road. The article was then transferred onto the left pan 31L at the transfer conveyor 41 position, and the cart changed direction at the end of the running path.
Transfer goods to the top.

Then, when the traveling cart is run and reaches the sorting chute position, the pan 31R or 3
The articles on the pan are unloaded onto the chute by tilting 1L as shown by the chain line in FIG.

If chutes for the same sorting destination are arranged on the left and right sides of the travel path for each pan on the left and right sides of the traveling trolley, it is necessary to first sort the goods into the corresponding sorting chute and then collect the goods for each sorting. Therefore, there is a problem that sorting efficiency decreases.

Therefore, in order to solve this problem in the present invention, for example, as shown in FIG.
The same sorting destination and the right chute are configured to merge into one place.

Therefore, since two articles can be simultaneously and independently loaded and sorted using two traveling carts, the sorting capacity can be improved with a simple configuration without increasing the speed of the traveling carts.

In addition, since the left and right pans can be tilted independently, the angle of inclination of the pan when loading goods can be made gentler, so when unloading from the sorting chute, the head difference between the sorting chute and the chute can be reduced, so there is no shock to the goods. and cause less damage.

〔Effect of the invention〕

According to the present invention, two pans are arranged on the left and right at the top of the traveling cart, and these pans are tilted independently, so that at least two pieces of cargo can be loaded and transferred with one traveling cart. , it is possible to improve the sorting capacity without running the trolley at high speed, and since the angle of inclination of the pan from the loading position to the unloading position is gentle, there is less baggage during unloading, and it is possible to improve the sorting capacity of round items. However, it also has the advantage of being able to be classified.
