Description

Automatic mechanical member sorter

Technical field the present invention relates to machine-building and automation field, is used for the intensive manufacturing of the same type, many kinds part of processing, and is a kind of equipment that the product that processes is mixed type concentration of transmissions and fast automatic identification letter sorting.

Background technology is of the same type, many kind machinery spare and accessory parts such as automobile brake disc, water pump spare, piston, in the professional production of tire and steel ring etc., for boosting productivity, excavating equipment and workshop potentiality to greatest extent, usually adopt tens of patterns to organize production with concentrated compact Layout of production line of identical device configuration and certain adaptation of product, because description and order goods batch various, resemblance is similar, bring very big difficulty to organization of production, it is temporary to need to do the container classification with a large amount of charging baskets in the production, after waiting for by the gross completion of processing, just can enter follow-up non-machining processes as cleaning, surface treatment and packing etc., all these work are at present mostly finished by manual.There is following drawback in this pattern: the one, and finished product is obscured easily; The 2nd, charging basket is temporary, causes the machined finished product to overstock in a large number; The 3rd, each batch part deadline is uneven, brings confusion for non-machining processes rhythm of production such as follow-up cleaning, surface treatment and packing; The 4th, the blank of different product and finished product handling workload are big, and transport passage for transporting takies the workshop useful space in a large number.

Summary of the invention the invention provides a kind of system---automatic mechanical member sorter that mixes the type concentration of transmissions and sort automatically based on the part of REID at these problems.This equipment adopts and transmits hook chain the machined production line finished product that rolls off the production line is mixed type in real time and hangs and spread out of, enter subsequent treatment district and off-sorting station successively, the finished product of handling through subsequent handling, this letter sorting system sorts automatically to finished product, can solve that finished product overstocks, middle turnover is loaded down with trivial details, easily obscure and subsequent handling and machining processes rhythm of production matching problem.

For convenience of description, the present invention is divided into machined district, workpiece post processing zone and three parts of off-sorting station with the workshop, as shown in Figure 1.The present invention partly is made up of Card Reader checkout gear and Card Reader tripping gear, industrial computer and dc source etc. that the standard industry hook carries stretched wire, trigger-type to link up with, equate with machined line quantity, as shown in Figure 2.In the machined district, the outlet of machine ledger line inwardly, by two row dense arrangement, with linking up with stretched wire with each production line product outlet, post processing zone, and sort bagging area and contact, on each hook, all fix an IC with the hook periodic duty, in the sorter control system, with the identifier of the IC-card machine identifier as the correspondence hook itself, this identification code and hook sequence number (manual identification number) have one-to-one relationship.Every production line in machined district is equipped with a Card Reader checkout gear, is positioned at hook stretched wire downstream separately; At off-sorting station, be provided with and production line Card Reader tripping gear one to one, i.e. sorting export, the hook stretched wire is wide U-shaped and holds the branch constituency, and tripping gear is layout entad.Each Card Reader checkout gear and each Card Reader tripping gear be all by bus and industrial computer communication, and by concentrated DC power supply.In industrial computer, be provided with hook state information table, virtual condition of each hook of expression, the present invention hook has 0,1,2,3 ..., K K+1 state value altogether, (K is a production line quantity), " 0 " represents empty hook, and all the other represent odd part, and part is that the production line of state value correspondence is hung.For convenience of description, Fig. 1 and Fig. 2 are to be that example illustrates with 36 production lines.Industrial computer enters arbitrary hook the production wire size that occurs part behind the machined district for the first time automatically, as the state value of this hook, and is retained to workpiece and breaks off relations and discharge, and after the unhook, system is automatically with its state value zero clearing.As the 1st corresponding the 1st IC-card of hook, if hang the line part No. 7, then this hook state value is 7, carries out at the 7th passage of off-sorting station and breaks off relations, and the back state value that breaks off relations becomes 0.If a certain hook state value is " non-zero ", then when its process subsequent production line, although also detect " having ", control system still keeps the previous status value, until unhook.The Card Reader checkout gear of each production line of industrial computer high-velocity scanning and the information of uploading of Card Reader tripping gear are therefrom caught and are risen to the bait and unhook information, and refresh the content in the hook information table in real time.

In the machined district, each production line finished product is manually risen to the bait at the station of inspection eventually separately, directly hang up on the empty hook of arbitrary process, the Card Reader checkout gear of each line correspondence is positioned at separately the downstream of inspection station eventually, read the identifier (card number) of the hook of process one by one, and detect simultaneously on this hook and have or not part, if on a certain hook, detect part, the Card Reader checkout gear is with oneself production wire size and hook identifier, be uploaded to industrial computer through bus, industrial computer inquiry hook state information table is judged whether up-to-date detected part is up-to-date rising to the bait, thereby is determined whether to rewrite the state value of this hook.

In a minute constituency, carrying the stretched wire hook of different workpieces successively through each sorting outlet, the Card Reader tripping gear reads card number by hook and uploads industrial computer, if the current hook state value of a certain Card Reader tripping gear is its pairing production wire size just, then industrial computer is assigned the instruction of breaking off relations to it, Card Reader tripping gear instant action, touching hook trigger discharges workpiece; If not, then be failure to actuate, thereby finish the letter sorting of part.Control system also has demonstration, counting and statistical function.

Advantage of the present invention and good effect mainly show in the following areas:

1, workpiece directly hangs and is sent in each tripping gear, and the hook stretched wire is wide U-shaped and holds the branch constituency, and tripping gear is layout entad, and logistics is unobstructed, saves the space.

2, Grading System is provided with real-time hook state information table on industrial computer, the Card Reader checkout gear is established in stretched wire downstream at every production line, automatically discern the source of workpiece by industrial computer, it is simple to operate on the one hand workpiece to be risen to the bait, the direct screening workpiece, need not any other additional operations, reduce labor intensity, avoid the human operational error, owing to the identifier to IC-card itself only carries out read operation, do not carry out write operation on the other hand, not only accelerated system identification speed, and make full use of the magnanimity Card Reader life-span number of times of IC-card, and prolonged the service life of IC-card greatly, realized quick letter sorting.

3, adopt single-wheel guiding ratchet trigger-type hook, have the load-bearing wide ranges, simple in structure, break off relations rapidly, the unhook active force is little, do not influence advantages such as hook stretched wire operate as normal.
