Description

Technical Field

[0001] The utility model relates to the technical field of cross-belt sorters, in particular to a sorting trolley power supply system relying on medium frequency power supply and capacitor power supply. Background Art

[0002] In modern industrial manufacturing, the logistics industry and logistics equipment are developing rapidly. In order to improve operational efficiency, automatic material sorting technology is particularly important. Among them, cross-belt sorters have the advantages of high efficiency and low breakage rate and are gradually replacing traditional manual sorting.

[0003] At present, all cross-belt sorters basically rely on medium frequency power supply systems to achieve contactless power supply in order to reduce friction and provide reliability of power supply equipment.

[0004] However, since the cross-belt sorter is equipped with dozens or even hundreds of sorting carts, these sorting carts may perform a few, dozens, or even all sorting cart actions. Therefore, when designing the medium-frequency power supply, it is necessary to consider the power required for all sorting carts to be in action, and the power of the medium-frequency power supply device must be set to a large power. However, since the probability of dozens or even all sorting carts being in action is very low, the high-power medium-frequency power supply device is very wasteful, resulting in the frequent occurrence of large horses pulling small carts, wasting energy and causing the cross-belt sorter to be very expensive, which is not conducive to the sales of the cross-belt sorter. Utility Model Content

[0005] The problem to be solved by the present invention is to provide a power supply system for a sorting trolley that relies on medium frequency power supply and capacitor power supply, in order to solve the problems of high cost and large energy waste caused by the sorting trolley in the existing cross-belt sorting machine relying solely on a medium frequency power supply device for power supply.

[0006] The problem to be solved by the present invention can be achieved through the following technical solutions:

[0007] A sorting trolley power supply system that relies on medium frequency power supply and capacitor power supply includes a cross-belt sorter, wherein a plurality of sorting trolleys are arranged on the cross-belt sorter, and the plurality of sorting trolleys rely on linear motors to circulate on the track of the cross-belt sorter; the sorting trolleys are electric sorting trolleys, and the plurality of sorting trolleys rely on medium frequency power supply devices for power supply, characterized in that the power of the medium frequency power supply device is greater than the power of one sorting trolley but less than the sum of the powers of all sorting trolleys; and further includes at least one medium frequency power supply pickup and at least one capacitor, the capacitor being connected in parallel in the power supply circuit between the medium frequency power supply device and the sorting trolley, the medium frequency power supply pickup charging the capacitor, and when the plurality of sorting trolleys need to move, the capacitor discharges to drive these sorting trolleys to move.

[0008] In a preferred embodiment of the present invention, the intermediate frequency power supply pickup and the capacitor are installed on a sorting trolley.

[0009] In a preferred embodiment of the present invention, the capacitor discharge power is at least equal to the sum of the powers of all sorting carts.

[0010] In a preferred embodiment of the present invention, the capacitor is a supercapacitor.

[0011] Due to the adoption of the above technical solution, the sorting trolley power supply system of the utility model relies on medium frequency power supply and capacitor power supply to power all sorting trolleys on the cross-belt sorter, which can reduce the power of the medium frequency power supply device and use the low-power medium frequency power supply device to charge the capacitor. When several sorting trolleys need to move, the capacitor discharges to drive these sorting trolleys to move.

[0012] The utility model reduces the power of the medium frequency power supply device, reduces energy consumption, and further reduces manufacturing cost and operation cost. BRIEF DESCRIPTION OF THE DRAWINGS
