Description

The technical field to which the invention relates.

The present invention relates to devices for receiving and accumulating non-rhythmically incoming piece parcels and for issuing these packages for further processing. The device can be used at postal, enterprises in automated parcel processing lines.

The level of technology

Known drives that provide single-layer accumulation of parcels. An example of such drives is the patent SU 1578073 A1, authored by A.L. Resurrection and V.S. Grigorieva, year 1988, is a surface for the accumulation of goods, consisting of the input and output parts as well as the partition between them.

Patent DE 59907629, authored by Heins Linder, year 1999, includes two conveyors, one of which is equipped for intermediate storage and a loading station.

The main disadvantages of these technical solutions is low capacity due to single-layer accumulation. They also do not dispense delivery — all accumulated packages are delivered for unloading.

The closest to the stated technical solution is the copyright certificate №332000 for the authorship Darsavilidze S.Ya., Dergachev Y.A., year 1970.

This device is designed to receive and accumulate non-rhythmically incoming piece parcels and deliver these parcels for further processing and can be used by postal companies when processing parcels. The device contains a support frame, with loading and loading chutes installed on it, and a feeding conveyor with skly. A feature of this invention is the simplified design due to the exclusion of the plow-down device (a fixed door is mounted at the end of the conveyor) and a slip-off with a varying angle of inclination (the upper part has a greater angle of inclination). An additional conveyor is installed at the bottom of the drive, with the board inclined more than 45 °, which prevents parcels from getting stuck.

The disadvantage of this device is the accumulation in one layer on one large drive, made in the form of a slide. This leads to a smaller capacity compared with multilayer accumulation.

Summary of Invention

The problem to which the invention is directed is to increase the capacity of the complex and ensure the metered delivery of parcels for further sorting.

This problem is solved by placing a number of gravitational drives under each other. Each drive is equipped with a chain conveyor with two rods that serve to load and unload the drive. The drive is alternately filled with a loading conveyor equipped with passive dumpers with an individual drive.

After filling, the accumulators can be alternately opened for unloading onto the discharge conveyor passing under them. To control the accumulators, the intermediate accumulation and dosing package for sorting is equipped with an operator’s console.

The technical result provided by the above set of features is an increased capacity of the intermediate accumulation complex and the ability to carry out a metered delivery of packages for further sorting.

FIG. 1 - General view of the complex of intermediate accumulation and dosage of packages for sorting;

FIG. 2a - Filling the first drive;

FIG. 2b - Filling the second drive;

FIG. 3 - Storage complex.

The implementation of the invention

A general view of the complex of intermediate accumulation and dosage of packages for sorting is shown in FIG. 1. The main elements of such a complex is a loading conveyor 1, equipped with ejector devices with drives 4 and a fixed ejector 5 at the end, located below each other drives 3, equipped with a screw descent 14 and discharge conveyor 2 located under the drives 3. Elements of the complex are fixed on a spatial frame from channel steel. Loading 1 and unloading 2 conveyors are belt conveyors, with rubberized tape as a carrier and traction unit.

The dumpers 4-5 are designed to move the parcels 15 from the loading conveyor 1 to the corresponding drive 3. This design uses passive dumpers 4 with an individual drive, to bring them into the working and non-working position.

The accumulators 3 used in this intermediate accumulation complex are mechanized accumulators of parcels with a fixed accumulation surface. This drive is shown in FIG. 3. The main elements of the drive is an inclined chute 6 with sides 9, on the sides of which there are two chains 10 with rods 11 and 8. One of them serves to hold the parcels 15 when loading, the second - to force the drive to unload. Chains 10 with rods 8, 11 fixed to them are part of a chain conveyor 12. The unloading conveyor 2 is located under a row of accumulators 3, at a distance necessary for the free passage of parcels 15 under other accumulators 3. 7. The movement of the parcels 15 in such a drive is a start-stop and is controlled by the sensor of the presence of a parcel 13 at the entrance of the drive. The surface of the drive 3 is made of a smooth metal, which contributes to a better filling of the plane of the drive.

To control the complex is used remote control. The workplace of the operator of the sorting complex is equipped with a display showing the state of the accumulators of the intermediate accumulation complex of parcels, as well as control buttons. Information about the state of the accumulators of the intermediate accumulation complex comes from sensors that track the location of the loading bar. Thanks to the information from the display, the operator can decide which drive to put into unloading mode in order to deliver packages for sorting. The workplace is also equipped with buttons for starting and stopping the unloading and loading container and buttons for opening the drives for unloading and emergency stop buttons for the complex. It is worth noting that the operator cannot simultaneously start unloading from more than one drive, as the discharge tray of one drive will block the way for the parcels unloaded from the other drive, which can lead to jamming and dropping of the parcels from the conveyor. Due to the alternate opening of the drives, the dosed supply of parcels for sorting is carried out.

The device works as follows. Initially, all the jumpers 4 are in working condition (Fig. 2a). On the loading conveyor 1, the parcels 15 reach the first ejector 4, and when the parcel 15 touches the surface of the ejector 4, a component of the friction force of the parcel on the tape appears along it, which causes the parcel to be reset to the drive through screw descent 14.

After filling, the drive 3 is blocked, and the first ejector goes into a non-working state, and the following parcels go to the second ejector and the corresponding screw release 14, filling the second drive (Fig. 2b). The last accumulator 3 is filled by the fixed diverter 5. After the accumulator is filled on the console, the light comes on, and the complex operator can give the command to open the accumulator for unloading and for starting the unloading conveyor 2.

After the operator's command, one of the accumulators 3 opens for unloading, the parcels under the action of gravity and under the influence of the unloading rod 8 fall on the unloading tray 7, which delivers the parcels to the unloading conveyor 2 passing under the row of accumulators 3. The unloading conveyor 2 in turn moves the parcels to the sorting plant.

The introduction of a complex of intermediate accumulation and metered delivery of parcels for sorting into automated parcel processing lines will provide a higher packing density, due to which the capacity of the complex increases, as well as the complex will provide an automatic metered flow of parcels for sorting.
