Our solution

Customer deals in the machinery business, especially in the automotive and fastener industry, they offer complete solutions in respect of providing system and spare parts to the customers in Turkey.

This customer has various kinds of material and a larger size range, the longest screw to be 70mm, 4 or 9 or 15 or 38, or 176 pcs per bag and required high counting accuracy.

Visual counting machine with strong compatibility so able to pack different kinds of material but with max material length below 40mm, and suitable for larger quantity per bag.

Weigher is able to pack different products but there will be about 1%~3% tolerance, so only the vibrating hopper is more suitable now.

Normally don’t suggest that one machine pack so much different kinds and sizes of products also takes too much time to adjust the hoppers . For example for a washer, if the thickness is below 0.5 mm to easily overlay, for the bolt, if the hopper packs 80mm then need to be a bigger one but when this bigger hopper pack screw of 16 mm then it’s too big for it, easy effect the accuracy and take time to adjust. Even if you add an en checker, if too many bags are picked up then the speed is very slow. so we suggest customer that one machine is for the main size products, and for the other size if the test is ok then ok. Finally, we suggest 9 hoppers at least for this customer with a PE bag machine.

There are 2 kinds of machine layouts,

Option1 is 9 hoppers with a middle conveyor like below picture, the advantage is hopper height is about 800mm, conveniently manually feeds material in the hopper, or manually adds other products which are not suitable for hopper counting so needs manual feeding in the conveyor, move to the packing machine for bag sealing only. When you pack any kind of product you only need to press the hopper no on or off via the packing machine touch screen. As customer pack only one kind of product in each bag and have limited space for a machine so we designed option 2 for them.

Option2 is each hopper table with moving casters, so when the customer needs to pack A product then move the A hopper close to the packing machine, pack B then move A hopper away and move the B hopper close to the machine instead, no need middle conveyor, no need complicate machine system, save cost and room space.


Customer Question & Our Answer:

1 Q: We see there are weigher and counting machines, what’s the difference?

   A: Counting machine and weighing machine are both able to measure the hardware parts.

The advantage of the counting machine is high accuracy and able to mix packing with several different hoppers, the disadvantage is speed is not faster and normally, tolerance is 0.1% according to quantity, and the speed is 100~500pcs per vibrating hopper according to products length and shape, and one vibrating feeder only able to pack similar products in shape and size. There is another visual counting machine, tolerance is 0.01% according to quantity, speed is 5~10 bags if 1000 pcs per bag, one machine able to pack different shapes and size products in a certain range.

The advantage of the weighing machine is fast speed, normally 10~45 bags per min if below 1 kg, and one machine is able to pack different shapes and size products in a certain range, the disadvantage is there will be about 1~3 pcs more or less each bag, and as it is very fast, so suitable for high-capacity products, for example, one same product needs to weigh at least half a day and then change to another product, there also needs time to adjust the machine for different products.

2 Q: What’s the advantage of your hopper counting machine?

   A: Optical fiber from Japan Keyence, area detect. Hopper from Taiwan China, a durable, intelligent control device, fully automatically changes vibrating frequency according to the quantity in the hopper, the screw will reduce when packing. Full stainless steel.

3 Q: What is the difference between detect box and the end weigher checker? Detect box detecting wrong quantity how? By weighing?

     A: Detect box is an optional device installed between the hopper and the packing machine, when the machine detects the counting qty is wrong, the detect box will open another side to avoid the wrong qty following into the packing machine.  sometimes the counting speed is very fast and one more pc product may follow down before the hopper cylinder is closed, the fiber recognized one more pc then the detect box will open another side and reject the material. pls check the video (at 1.15)

But no fiber counting accuracy is 100%, our fiber counting accuracy is 1/1000, detect box is unable to recognize the 1/1000, so need an end weigher checker to reject via weight. The weighing checker will reject the finished bags whose qty is wrong. Even though the end checker will reject the wrong bag but it wastes time, and need workers to tear the wrong bag and put them into a different hopper, and recount again. Please note if your material has much weight tolerance itself or too much different kinds of material mixed together, for example, 50 pcs small washer which a unit weight is 0.5g/pcs, but there is 0.011g weight tolerance itself(0.511g/pcs) then there may be about 25~25.55g per bag even qty is 50 pcs. when bags whose weight is 25.55g pass through the end weigher, the weight is over the target tolerance of 0.5g, so the weigher will reject this bag even if the qty is 50 pcs.Pls see the end weigher video

4  Q: Is your Printer able to make this label?

  A: This is a label stick machine, you can order a printed label roll if the information is not changed, if the information changes then need a printer and label stick machine together, the machine cost higher and need a label cost. You can try to use the thermal printer which directly prints the information on the bag after you edit the content and inset via touch screen. Numbers, LOGO, and barcode. Different models according to your printing size range.WE-01 printer size is 24*40, WE-03 is 32*50, WE-05 is 53*70, so WE-05 maybe ok.

5 Q: Why we can’t use one set end, weigher, for all these products?

   A: Each end weigher checker is suitable for finished bags in a certain different size and weight range, with accuracy different. WE-2000 model is suitable for your 90~260mm bag size range, but accuracy is 2g which means when you pack a small light washer which a unit weight below 2g then the end weigher checker is unable to detect the rejected bag if one pc more or less in a bag. You can choose your main product size and weight range.

6 Q: Please stick the CE plate, stick the plate showing hz/ model number / serial number/ your brand name.

   A:  If you do not have a CE certificate, pls send the Declaration of Conformity and Test Report you prepare while exporting your machines. The letterhead must be a Declaration of Conformity, not a Certificate of Conformity. The machine brand name and model name must be seen in the Declaration of Conformity. I need to have a sample document as it is. then my customer will be easy about clearing your machine from Turkey customs.

7 Q: Sometimes customers need to count materials into a bag and sometimes count into a box, our packing machine needs to reserve space so customers can put the box at the bottom to receive the counted nut bolt.

8 Q: Our customer needs this machine to pack different products into small bags,  maybe the machine pack product A 20 bags and then packs product B 50 bags, so the machine is able to fully automatically stop working when finished with 20 bags?

    A: Yes, the machine with this function. First set target bag qty 20 bags via touch screen then the machine will fully automatically stop working after it packed 20 bags. Please see the below video.

9  Q:  Our voltage is 380V/3 phase/50 Hz, if machine workable?

     A:  We can add a voltage transfer or you can change it according to the below explanation.

  •  If there is N wire

1、380V The voltage between the lines of the three-phase five-wire power supply is as follows.2、In the above power supply system, the single-phase socket voltage is 220V

3、Please check whether the voltage is 220±10%V before power transmission      If there is no N wire

10 Q: Can u give me the Hs code of WE-350X pls?


11 Will they be in wooden crates?

Yes, wrap with film first so avoid Moisture or salt water corrosion, then fixed with a wooden package like the below picture.
