Screw & Hardware Fastener Packaging Machine — Automatic Cartoning

Cartoning machine for screws, nuts, bolts and hardware kits

A hardware cartoner is the packing step after counting or weighing. Screws, bolts, nuts, washers or mixed kits arrive as a counted group and are loaded into a carton, which is then closed. This LINEVO configuration covers the cartoning step. Counting, weighing and bagging take place upstream; our engineering review coordinates their interfaces with the cartoner.

Define what reaches the cartoner: loose pieces, a counted group, or a bag or blister pack of fasteners. State the heaviest and sharpest item, the count or weight per carton, and the carton drawing. Those details decide the guides, pushers and carton board that need review.

Bagging or cartoning for fasteners?

A fastener packing machine in the common sense counts parts and drops them into a bag. A cartoner does something different: it puts a counted group, a bag or a kit into a folding carton. Many hardware lines use both, so state which result you need before comparing quotations.

• Retail and shelf use: a printed carton stacks, hangs or stands on a shelf and carries the label. A plain bag usually needs a header card, a tray or an outer carton.
• Sharp and heavy parts: a carton wall and the insertion guides take the load of heavy metal. A thin film bag depends on bag strength and seal quality, so test it with your heaviest part.
• Mixed kits: a kit of several part types is often counted into separate bags first, then boxed together. This is a bag-in-carton route; automated bagging units feed the cartoner upstream, with transfer and loading defined during line integration.
• Loose bulk fill: parts sold by weight or count in a single container may not need a folding carton at all. A bagging or weighing line is the better fit.
• What each route needs from you: bagging needs film type and bag size. Cartoning needs carton dimensions, board and closing method.

How the count reaches the cartoner

A cartoner packs what it is given. The count or weight is set upstream, and the carton line has to receive it in a form it can load. The usual upstream arrangements for hardware are a vibratory bowl or plate counter, an optical counter, and a multi-head weigher or checkweigher.

Configuration review covers synchronization with vibratory bowl counters or multi-head weighers, plus Siemens PLC/HMI monitoring, incomplete-box rejection and fault diagnostics. Our engineers define the required signals and checks for your line.

If your counter or weigher already exists, send its make and model, discharge height, signal type and output. LINEVO can then review how the two machines hand over a count, what the cartoner checks before closing a carton, and where rejected cartons leave the line.

• Who supplies the counter or weigher, and who connects the signals between the machines
• What the cartoner receives: a counted group, a bag, or a signal that a count is ready
• What is verified before a carton is closed (missing pieces, missing carton, flap state) and how an incomplete carton is rejected
• Where rejected cartons leave the line, and who clears them
• Which throughput and fault information the HMI shows

Mixed kits and format changes

For assortment kits, write down the composition before the quotation: how many part types, how many of each, whether each type is bagged or placed loose, and whether the carton has compartments. A kit with many part types needs more feeding points than a single-item carton.

For several carton sizes or kit assortments, ask which parts change, which settings are made by dial, and what the changeover involves. Format review covers tool-less changes with digital-dial settings; we establish the changeover sequence and time for your formats.

Coding and labeling on the carton

The configuration lists real-time labeling and coding systems among the items to review. Say what must appear on the carton: batch or date code, a barcode, a product label, or a printed count. Then confirm which equipment applies it, at which station, and whether it is included, optional or supplied by another party.

Heavy parts, wear and frame

Metal parts can puncture carton walls, tear corners or jam during insertion. Handling options include hardened guides, shock-absorbing loading mechanisms, reinforced pushers and abrasion-resistant feeding surfaces. Test them with your heaviest and sharpest part and your actual carton board.

Frame review covers powder-coated reinforced steel, SUS304 stainless steel and carbon-steel reinforcement. Our engineers define the materials and finish for the machine, especially for oily or dusty workshops.

What to send for a hardware cartoning quotation

Group the information so each part of the line can be reviewed. Samples help most when they include the extremes of your range.

• The hardware: photos or samples, the heaviest and sharpest item, dimensions, and the count or weight per carton
• The carton: dimensions or a drawing, board material, closing method and any print requirements
• The upstream equipment: counter or weigher make and model, discharge height, signal type and what it delivers to the cartoner
• The target and the site: output per minute or per shift, the formats to change between, voltage, phase and frequency, and compressed air

Hardware cartoning questions

Does this machine count or weigh the fasteners? Counting and weighing take place upstream. This cartoner receives the prepared groups through an interface to the counter or weigher; our engineers define the transfer signals and equipment arrangement.

Should I use a bagging machine or a cartoner? It depends on the finished pack. Loose parts sold by count or weight in a bag need a bagging line. Parts sold in a printed carton, kits and heavy items usually need a cartoner, sometimes after bagging. State the retail format, the heaviest part and the outer carton before deciding.

Can one machine run screws, bolts, nuts and mixed kits? These are applications for this configuration. Suitability depends on the item, the count per carton and the carton, so send representative samples for review.

Can it connect to coding or labeling? Real-time labeling and coding systems are listed as items to review. Confirm the code content, position and the equipment that applies it.

Will heavy metal parts damage the carton? The handling configuration uses guides, loading mechanisms and pushers to protect the carton. Verify this with your heaviest, sharpest part and your carton board during sample review.

What output can I expect? We define output for your application. It depends on the hardware item, the count per carton, the feeding arrangement and the carton format, so ask for a rate tied to your own pack.

What does the price depend on? The quotation depends on the counting or weighing interface, how the product is fed, the carton and closing method, whether coding or labeling is included, and the formats you need. Send the details listed under “What to send for a hardware cartoning quotation”.
