Parcel distributor, especially for stores

Abstract

The parcel distributor is a modular set with additional storage module in the form of a ceiling box set on a corner box to which it is rigidly connected and coupled by a cantilever lift mounted in a vertical shaft formed in the support rack frames in both boxes. In each module, between their cantilever racks, there is an electrically driven Cartesian manipulator. On the Cartesian manipulator trolley, there is a grabbing mechanism for taking trays from the front or rear cantilever rack. The window for sending and collecting parcels in the distributor is a locker, preferably in the operating panel, which has an electrically lifted lock cooperating with a ratchet lock and limit switches blocking its lower position when the locker door is open.

DESCRIPTION

(25) The parcel distributor is a modular set consisting of a corner box 1 with an operating panel 2, which is the basic module of the distributor, and a ceiling box 3 set on it, which is an additional storage module, rigidly connected to each other, whereby a cantilever lift 22 is embedded in both boxes in the space above the operating panel 2, whose height is correlated with the storey height of the ceiling box 3. Both boxes are in the form of a cuboidal block protected with covers 4, whose frame is a rack frame 5.

(26) On the front and rear sides of the rack frame 5 there are cantilever racks 6 designed for hanging trays 7 on one side, on which parcels, whose base dimensions are allowed by tray 7, are stored. The spacing between the racks determines the tray 7 suspension column, and the rack brackets 8, arranged in modules at fixed heights, determine the tray 7 suspension storey. Between the cantilever racks 6, there is an electrically driven Cartesian manipulator 9 with a trolley 10 moving in the Cartesian system. The outer frame 11 of the manipulator is stationary and rigidly connected to the rack frame 5, while the inner frame 12 of the manipulator 9 is moving horizontally in the outer frame 11, and the trolley 10 of the manipulator 9 is moving vertically in the inner frame 12. The arrangement of two toothed drive belts 13 routed and fastened to the trolley 10 in the Cartesian manipulator 9, as shown in FIGS. 9 and 10, allows to set its vertical position in a programmed tray 7 suspension column, as well as its horizontal position, on a programmed tray 7 suspension storey. Each drive belt 13 has a belt tensioner 14 attached to the outer frame 11.

(27) On the trolley 10, there is a grabbing mechanism 15, which allows for double-sided extension of the transport tray 16 to take trays 7 from the front or rear cantilever rack 6.

(28) The gripping mechanism 15 is made up of two bendable carrying arms 17 mounted on the extension shaft 18 which is driven, through a gearbox, by an extension motor 19 mounted under the trolley 10.

(29) The multi-joint, bendable carrying arm 17 has a two-stage chain transmission. The carrying arm 17 has two self-aligning carriers 20 with a chain transmission in both carriers and epicyclic gears in the joints of the carrying arm 17, which ensures a constant level of the transport tray 16 during its extension to the front or rear cantilever rack 6.

(30) Each chain carrier 20 of the carrying arm 17 consists of two pull-out elements with chain wheels and have a chain tensioner 21 in each carrier 20, as shown, e.g. in FIGS. 12 and 17.

(31) Lift 22 is mounted in a vertical shaft formed in the front racks 5 in the corner box 1 and in the ceiling box 2. Lift 22 consists of a vertically moving two-cantilever trolley 23 with a lift 22 drive motor 24 attached to it. The trolley 23 moves on two vertical guides 25 attached to the rack frame 5 in the corner box 1 and in the ceiling box 2 of the distributor.

(32) Through gearbox, the drive motor 24 of the lift 22 cooperates with gear racks 26 which are also mounted on the rack frame 5 of the distributor. The lower and upper positions of lift 22 trolley 23 are determined by pinned bumpers and limit switches located on its travel route.

(33) The operating panel 2, as an independent sending and collecting module of the distributor, has a lighting shade 28 on the perimeter from the front, with a cord of light-emitting diodes, a control panel 27 at the top, and a locker under it for sending and collecting parcels.

(34) The operating panel 2 in other version can be a removable and mobile module, as illustrated in FIG. 23.

(35) Control panel 27 consists of the following elements:

(36) touch screen up to 12′ to operate the distributor interface

(37) payment terminal

(38) barcode/QR reader for customers and couriers.

(39) The locker constitutes a release window of the distributor and defines parcel dimensions, and the parcel height is correlated with the storey height of the ceiling box 3.

(40) The locker has an open frame compartment with a lower shelf 29 and side guides that lead to the tray 7. At the front, the locker has door 30 that is automatically opened by means of an electromagnetic lock and, at the back, it has an electrically lifted lock 31 cooperating with a ratchet lock 32 and limit switches 33 blocking its lower position when door 30 is open, to prevent unauthorised persons from getting inside the distributor.

(41) The lock 31 is driven by motor 34 which, together with shaft 35, is mounted on the upper wall of the locker. Through gear wheels 36 mounted on its ends, the shaft 35 cooperates with gear racks 37 mounted on the side walls of the lock 31.

(42) On the side of the locker, above its guides, there is a scanner for measuring the actual parcel height, which sends a signal to the system of automatic optimisation of storage space in the distributor.

(43) In the locker, in the shelf 29 guide, there is a sensor for determining the actual parcel weight, which sends an alarm, sound or light signal when the permitted parcel weight is exceeded.

(44) The distributor is controlled via the management software which records the distribution of all parcels and keeps their inventory in real time.

(45) The program selects and sets the free storey for storing the parcel. The gripping mechanism 15 takes tray 7 with a parcel from the locker's release window and moves this tray 7 to the free storey of the cantilever rack 6 and slides the tray 7 with the parcel underneath the other tray 7, while maintaining the programmed gap between the top of the parcel and the bottom of the tray 7.

(46) The distributor can be either corner box 1 with operating panel 2 or a combined modular set consisting of two corner boxes 1, including one, as the basic distributor module, with operating panel 2 as well as the ceiling box 3 rigidly connected to each other.

(47) The ceiling box 3 is mounted above store furniture, under the ceiling, on a self-supporting structure or with wall plugs.
