Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an automatic sorting input device used when sorting packages and the like.

(Prior art) In this type of conventional automatic sorting input device,
Skilled operators look at the information displayed on the parcels they are trying to sort and code the sorting destination by typing or voice input, or label the parcels to be sorted with barcode labels or text labels that correspond to the sorting destination. In order to have the machines read the barcodes and characters by pasting them on and giving them a predetermined distance between objects, operators had to line them up on the conveyor. Therefore, if an automatic sorting machine has multiple input sections, the same number of operators as the number of input devices are required.

(Purpose of the invention) The purpose of the invention is to develop an automatic system that transfers the parcels to be sorted onto a conveyor one by one at regular intervals without falling over, and in the unlikely event that the parcels that fall below the predetermined interval are removed. An object of the present invention is to provide a sorting input device.

(Structure of the invention) According to the invention, a barcode label with a sorting destination code is affixed to the baggage to be sorted, and the baggage is transferred onto a conveyor and inputted so that it can be conveyed in line without falling over. If the items are transferred at a predetermined interval, they are read with a barcode reader, etc., transferred from the input device to the sorting machine body, and after being transported to the position specified by the sorting destination code, they are sorted, and then There is provided an automatic sorting input device characterized in that the sorted items are excluded if the separation becomes less than a predetermined interval during conveyance due to some reason and processing cannot be performed.

(Embodiment of the invention) The present invention will be described in detail below with reference to the drawings of an embodiment of the invention. Figures 1, 2 and 3
The figure is a plan view and two side sectional views of the embodiment, and in the figure, 1 is a pan of the sorting machine main body (hereinafter referred to as pan), 2 is a fall prevention plate, 3 is a timing conveyor,
4 is a buffer conveyor, 5 is a control conveyor driven by a forward/reverse electric motor, 6 is a contact plate for changing the conveyance direction of the baggage at right angles, 7 is a supply conveyor, 8 is a baggage transfer machine, 9 is a baggage A feed conveyor that supplies the material to the transfer machine 8, from 10-1 to 10-
9 is a package to be sorted and has a barcode label affixed to it. The timing conveyor 3, buffer conveyor 4, and control conveyor 5 constitute an input section for carrying cargo into the main body of the sorting machine. Furthermore, BR is a barcode reader, and PH1 and PH2 are photoelectric switches. Figure 4 is an electrical control system diagram, PH1 and PH2 are photoelectric switches, AM1 and AM
2 is an amplifier that operates when the photoelectric switch is shielded from light and activates relays RL1 and RL2. rl1 and rl2 are contact points of RL1 and RL2, respectively. RL3 is a relay that controls the forward/reverse rotation electric motor M for driving the control conveyor 5, and rl3-1 and rl3-2 are its contacts.

Next, the operation of the present invention will be explained. The pan 1 has an endless rail driven by a chain or the like and connected in large numbers, and when the luggage loaded on the pan is transferred to the pan, the classification code of the luggage read by a barcode reader is read by a control device (not shown). ), and after conveying the bread to a predetermined position stored in advance, the bread is tilted and dropped. The cargo 10-1 is transferred from the timing conveyor 3 to the pan 1 and conveyed. At this time, the cargo is prevented from falling from the pan 1 by a fall prevention plate 2. Baggage 10-2 is on timing conveyor 3
The timing conveyor 3 is stopped and is waiting to be transferred to the pan 1. When the empty pan moves to a position suitable for transfer, the timing conveyor 3
is driven and the cargo 10-2 is transferred to the pan 1.
Next, the timing conveyor 3 is replaced by the buffer conveyor 4.
It stops when the cargo 10-3 on top is transferred.
Next, wait until the bread is moved to a position suitable for transfer.

The baggage 10-4 on the control conveyor 5 is transferred to the buffer conveyor 4, and the buffer conveyor 4 temporarily stops when there is a baggage on the timing conveyor 3, and if there is no baggage, it immediately transfers the baggage without stopping. Transfer to conveyor 3. In this way, luggage 10-2, 10-3, 1
0-4 are transferred to the pan 1 one after another and transported to the sorting destination. The sorting code of the baggage on the buffer conveyor 4 is read by a barcode reader BR and a sorting control signal is sent to a control section (not shown). Baggage is transferred to the supply conveyor 7 from the feed conveyor 9 via the transfer machine 8. Transfer machine 8
The transfer timing of the gate 8' is controlled (not shown) so that the cargo is conveyed on the supply conveyor 7 at regular intervals, and the gate 8' opens momentarily to drop the cargo onto the supply conveyor 7. Luggage 10-5 to 10-9
is conveyed while maintaining a constant interval, collides with the contact plate 6, and is transferred to the control conveyor 5. When the cargo 10-5 is conveyed to the position 10-5', if for some reason the cargo 10-4 is still on the control conveyor 5, the photoelectric switch PH
1. PH2 is shielded from light, amplifiers AM1 and AM2 work, relays RL1 and RL2 are activated, and their contacts rl1 and rl
2 is closed and relay RL3 is activated. Contact rl3-1 of relay RL3 opens, and contact rl3-2 closes. The driving electric motor M of the control conveyor 5 instantly reverses direction to remove the cargo 10-4. Photoelectric switch PH
When light passes through the motor M, the motor M rotates in the normal direction and operates normally.

(Operations and Effects of the Invention) As explained above, the present invention transfers the cargo to be sorted onto the conveyor one after another at regular intervals without falling over, and automatically detects when the interval falls below the predetermined interval. Since parcels that are closely spaced are eliminated to prevent jamming, there is no need for a worker to line up parcels as in the past, making it possible to make the fully automatic sorting input device extremely capable of processing. did.
