Checkweigher aut Weight Sorter: Quod ad lineam tuam convenit?
Areprehendo ponderator and a weight sorter both weigh, and both sit on a conveyor. One decides whether a pack may leave the factory; the other decides which grade a pack belongs to. Buying one when the line needed the other is an expensive way to find out.
One verifies, the other classifies
A check weigher is a gate. Every pack is weighed against a target and a tolerance, and the ones outside the tolerance are removed and recorded. The output is one decision per pack, and the evidence that the decision was made.
A weight sorter is a switchyard. Packs are weighed and then sent to one of several destinations, usually because each destination is a different grade, a different price band or a different customer specification. The output is a destination per pack.
Ambos pesant ad fractionem grammi, et neuter alterum substituit.
Quod ponderatoris verificatoris probare postulatur
Officium est adhaerentia et abusus: nullum pachymerum subpondus excedit, nullum superplenum foras exit, et decisio reiciendi in actis constat. Noster CQ-YWXP400 ponderator verificator ad aulam impacandi aptatus est, quae plures quam unum magnitudines pachymerorum tractat:
| Parametrum | CQ-YWXP400 |
|---|---|
| Rangus ponderandi | ≤ 15 kg per item |
| Minima scala | 1 g* |
| Praecisio in pondere | ± 1 g to ± 5 g |
| Velocitas lorum | 10–60 m/min, regulabilis |
| Perfusio | Usque ad 60 pecia/min |
| Cingulum ponderans | 620 x 400 mm |
| Maximum productum | ≤ 450 x 390 mm |
| Reiectio | Repulsor, Valvula, Flatus Aeris, Brachium Oscillans |
| Programmata reposita | 100, cum discipulatione automatica |
| Regulatio | schermum coloratum tactuale 7-pollicare, USB / RS232 / RS485 |
| Potentia | AC 220 V ± 10 %, 50 Hz, 400 W |
| Aer praebetur | 0.6–1 MPa pro apparatu reiciendi |
| Dimensiones | 2146 x 1110 x 1231 mm |
Everything in that table answers one question — inside the tolerance, or outside it. The hundred stored programmes exist so the check weigher can change pack without a rebuild; the four rejection devices exist so the same frame can remove a box, a bag or a bundle.
What a weight sorter is asked to do
A sorter appears where weight is a grade rather than a pass mark: produce sized into bands, portions matched into a batch, packs routed to different retail specifications. Our own description of the pondus sorter puts it as separating producta automatically against predetermined weight parameters, and the machina ponderis gradationis page adds the rest: multiple categories, load cells, and each item routed to its destination.
Two things follow from that. The number of destinations is a specification in its own right — a sorter with two outlets is not a small version of one with six. And a sorter's report is about distribution, not compliance: it tells you how many packs landed in each band.
Where each one sits on the line
Un balancier de contrôle se place là où l'emballage est terminé et la décision est définitive — après le remplisseur ou l'emballeuse, avant la mise en caisse. Son dispositif de rejet nécessite un endroit pour déposer un emballage défectueux, c'est pourquoi notre balancier de contrôle porte la section de rejet sur ses propres pieds : la commande pneumatique n'affecte jamais la cellule de pesée.
Un trieuse se place là où le poids détermine le parcours — à l'entrée pour les produits frais, à la sortie d'une balance multicellules, ou partout où deux spécifications sortent de la même machine. Si la ligne n'a qu'une seule destination, une trieuse n'a rien à rediriger.
Les trois chiffres qui décident cela
- Plage et résolution, ensemble. Le 1 g ci-dessus est la plus petite échelle que le balancier de contrôle peut résoudre ; la précision obtenue est de ± 1 à ± 5 g sur la plage de 15 kg. Comparez ces deux valeurs avec l'emballage le plus léger que vous traitez, car c'est là que la résolution s'épuise en premier.
- Débit par rapport à la vitesse du tapis. 60 packs a minute on this check weigher is a function of pack length and belt speed, not a separate dial. A pack longer than the weighing section allows takes longer to cross it, and the rate falls.
- Number of destinations. One reject outlet, or six grades. This number moves the price more than the weight range does.
What neither machine does
- A check weigher does not grade. It can tell you a pack is 12 g light; it will not tell you which of six bands the pack belongs to.
- A sorter does not produce a per-pack compliance record against a target and a tolerance. It produces a distribution.
- Neither of them finds a fragment of metal or a piece of glass. That is metal detection or X-ray inspection , and it is a separate decision made on the same belt.
- Neither one replaces a metallum Separator in parte superiori del processo, dove il prodotto è ancora in forma di polvere o granuli all’interno di un tubo.
Come redigere la specifica
Inviare cinque elementi e la quotazione per la bilancia di controllo cesserà di essere una stima approssimativa:
- Il pacco più leggero e quello più pesante, in grammi o chilogrammi.
- La tolleranza che si deve rispettare, e la sua origine — una normativa, un cliente o il proprio dosatore.
- Velocità della linea o numero di pacchi al minuto, e le dimensioni del pacco che attraversa il nastro trasportatore.
- Modalità di rimozione di un pacco difettoso: spinto, soffiato, lasciato cadere o deviato verso una categoria.
- Ambiente operativo: lavabile o asciutto, temperatura ambiente e aria compressa disponibile.
Questi sono i cinque elementi richiesti dal nostro stesso modulo di richiesta per la bilancia di controllo CQ-YWXP400 .
The range
Check weighers: CQ-YWXP400 for mixed light and heavy packs on one frame, YW-XP600 for customised and OEM builds, and the small-pack class in our bakery checkweighing case . Sorting: pondus sorter ,machina ponderis gradationis et logistics sorter for cartons and parcels. The two category pages sit under Reprehendo ponderator et Sorter .
Quaestiones Frequenter Rogatae
Can a check weigher sort packs into grades?
Not into grades. It sends a pack to a reject outlet or leaves it on the line, which is one decision. Grading into several bands is a sorter's job, and the destination count is what separates the two machines.
Quam bene potest ponderare ponderator exactus in parvis pachetis?
Exactior quam cernitur in tabula supra. Noster casus de panificatio exegit ponderatorem exactum ad ±0,1 g et 200 pacheta per minutum in pachetis panis et pastillarum — cingulum angustius et cellula oneris exactior quam in cingulo 15 kg. Dic nobis pondus pacheti et tolerantiam, et dicemus quae classis conveniat.
Num opus est mihi ponderatore exacto et sortitore?
Solum si linea duas habet functiones: portam ad observantiam et decisionem de directione. Multae lineae tantum portam ad observantiam requirunt, nihil aliud; et sortitor emptus pro linea unius destinationis nihil habet ad commutandum.
Num ponderator exactus substituit metal Detector ?
Non. Ponderatio et detectio corporum alienorum diversa quaerunt in eodem cingulo. Linea quae utrumque requirit duas machinas in serie habet, aut unam integratam machinam cum detectoribus metalli et ponderatore exacto.
Quid si pachetum meum longius est quam sectio ponderandi?
Send the pack length with the enquiry. The XP400 check weigher takes packs up to 450 mm on a 620 mm weighing belt; anything longer needs a longer frame or a slower belt, and the throughput figure moves either way.
Two machines, two questions: may this pack leave the factory, and where does the pack belong. Settle those two separately before you ask for a price, and the quotation will be for one check weigher instead of two half-machines.
Send us the pack range and the tolerance, and we will tell you which of the two you actually need.
