Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an apparatus for automatically sorting packages such as parcels by various items or by delivery area.

[Conventional technology]

Conventionally, automatic baggage sorting equipment runs multiple carriers on endless rails or chains, loads the baggage onto a baggage holder that allows the tray to tilt at a fixed position, and then runs until the tray is in a predetermined position. When the chute position for sorting is reached, the baggage holder is tilted to unload the loaded and transported baggage.

However, the structure of the device that sets the tray at a position where cargo can be loaded and tilts the set tray so that cargo can be unloaded at the sorting position is complex, has many components, is expensive, and lacks reliability. There were also problems that required maintenance.

[The problem that the idea attempts to solve]

The present invention has been made in view of this, and an object thereof is to provide a baggage sorting device consisting of a tray tilting device with a simple structure.

[Means to solve the problem]

The V
A tray piece is formed in the shape of a letter, and one of the tray pieces is selectively tilted, and a setting fitting fixed to a support shaft connected to the cartridge is provided at the bottom of the tray piece, and the tray is tilted by a setting roller and an operating lever. A lever device for tilting the tray is provided on the side of the carriage, and the tray piece is tilted by tilting the lever device for tilting the tray.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes an endless chain, which is driven and is provided with a large number of carriages 2 at arbitrary or fixed pitches.
The carriage 2 is supported by running rails 3 arranged along the endless chain 1 so that the endless chain 1 is fitted therein, and the carriage 2 is supported by running rails 3 disposed along the endless chain 1. Running wheels 4, 4 for receiving vertical loads are provided, and in addition to these running wheels, a horizontal guide wheel 5 is provided at a position above the running wheels 4 and approximately at the center of the carriage 2, and at the center of the top of the carriage 2. Moreover, one support shaft 6 is provided at the top of the carriage in the longitudinal direction of the carriage, that is, in the direction of movement.
The support shaft 6 supports the lower ends of a pair of tray pieces 7, 7 forming a tray facing each other in a V-shape. End plates 8, 8 are provided at both ends of the tray pieces 7, 7.
When the trays are closed together to form a V-shape, both end faces of the tray are also closed, and at the lower end of each tray piece 7, a set fitting 9 that is rotatable about the support shaft 6 is provided to protrude diagonally downward. However, by setting the mounting positions of the setting metal fittings 9 of each tray piece at different positions with respect to the moving direction of the carriage, it is possible to prevent them from interfering with each other. Further, one or more torsion springs 10 are supported on the support shaft 6, and both ends of the torsion springs 10 are respectively supported by spring stops 11 protruding from the back surface of the tray piece. 7 can also be set in the direction in which it is always open.

Further, two sets of tray tilting lever devices 12 are provided on the left and right sides of the carriage 2 to tilt each tray piece. are opened and closed independently. This lever device 12 for tilting the tray has a set roller 12b attached to one end of a shaft 12a which passes through and supports the cartridge main body horizontally.
, with an actuating lever 12c protruding from the other end,
The set roller 12b projects upward from the shaft 12a so as to face the set metal fitting 9 protruding below the tray piece, and comes into contact with the set metal piece when the tray piece is closed. Using the lever operating piece 14 installed on the fixed side, the tip of the lever comes into contact with the lever operating piece 14 when the cartridge moves to the fixed position, and the setting roller is moved diagonally downward so as to swing away from the setting metal fitting. protrude in the direction A return spring 12d is attached to this lever device.
In addition, stoppers 13 are provided on both sides of the cartridge 2 to protrude horizontally, so that the tilted tray piece 7 comes into contact with the stoppers 13 at a predetermined position and is stopped. In the example, the stopper 13 is brought into contact with the rear surface of the tilted tray piece at a position that is in line with the tray piece on the side that is not tilted. At this time, instead of directly abutting the back surface of the tray piece against the stopper, reinforcing ribs 7a provided on the back surface of the tray piece may be brought into contact with the stopper 13.

Therefore, when the carriage configured as described above is conveyed along the traveling rail by the drive of the chain, the tray of the cartridge in the loading position has a closed V-shape as shown in the figure. When the desired cargo is loaded and the carriage travels and reaches the set position, the lever 12c provided on the opposite side to be unloaded is pushed up using a lever operating piece etc. made freely retractable by a hydraulic cylinder, solenoid, etc. The set roller of the lever device swings and is removed from the set metal fitting. As a result, the tray piece connected to the set fitting is forcibly rotated about the support shaft 6 by the torsion spring 10 and tilted to a position where it comes into contact with the stopper 13. In this case, the load on the tray piece may also act. The cargo in the tray falls along this tilted tray piece due to its own weight, and is unloaded.

At the time of unloading, a torsion spring is provided so that the tray can be forcefully tilted more quickly than the self-weight type.

Furthermore, when the cartridge runs after unloading, a fixed guide rail (not shown) installed immediately after the unloading position or at a fixed position on the traveling rail comes into contact with the back surface of the tray piece or the reinforcing rib, and the tray piece is twisted by this guide rail. When the lever device is pushed up against the spring and restored to its original position, the lever device is pulled by the spring 12d so that torque is constantly generated in the direction of pushing it against the setting metal fitting, so the setting roller slides along the side of the setting metal fitting. When the tray piece is fitted into the fixed position of the setting fitting and set, the tray piece maintains its V-shaped cross section. The carriage travels in this state, and when it reaches the loading position, the next load is supplied again. In addition to the V-shape, the tray may also have a morning glory shape.

[Effect of idea]

According to the present invention, V-shaped tray pieces that face each other and are tiltably supported by support shafts are always held in the desired tray shape using a set metal fitting and a lever device, and loaded and transported, and unloaded. When the carriage reaches the position, the tray piece on the side in the direction of unloading is disengaged from the set roller and the lever device, so the tray piece can be quickly tilted and unloading can be done reliably and quickly. , a setting metal fitting, and a lever device for tilting the tray are provided in the center of the cartridge, so the structure is simple, the number of component parts is small, reliability can be improved, and maintenance is easy.
