Tension Control with Load Cell

 

          By using RS Load Cell, tension and relaxation that occur during reeling and discharging are gotten under control and so the negativities are expelled.   It can be applied in front of Charging roller or to the back of Reeling roller or both. System is basically shown in above pictures. In this picture, there are two RS Load Cell are mounted on the roller in front of the charging roller. The tension force that occurs as the roller start to charge is transferred to load cell. The decrease or increase taking place in tension is sensed by load cells and transmitted to tension control indicator. Tension control indicator system declines it to tension set value, which was recorded its memory before. Thus, the tension is brought under control.

Silo Weighing Application

      ST, ST-2W or HT series load cells can be used in silo weighing applications. The point to be considered is that there must not be any stretch in the system. These load cells give maximum performance when the yare used with appropriate kits. The negative effects such that above mentioned stretch and load do not locate on load cell are eliminated. 

Vibratory Bowl Feeder Application Sheet

        When plastic parts are placed in a vibrating bowl feeder, the friction causes them to charge. The charged parts then can jump out of the bowl, stick to machine casing and other earth potentials or cause m?sfeeding.

        By positioning a PULS Electronic Pulse DC bar above the vibrating bowl feeder, you will bathe the entire area in ionised air removing any possibility of stat?c being generated and removing the opportunity of M?sfeeding, sticking and material misbehaviour.

Laminating Application Sheet

        When laminating or bonding two or more surfaces together, problems can arise when static charges can force the surfaces apart. If using an adhesive or weld tool, you require the surfaces to be flush and without creases or curls.

        By passing the material after assembly under a charge bar (An earth or ground is required on the other side) you can bond the stack together for a short while. When bonding larger stacks, two charge bars are required (One either side of opposite polarity). This will hold the stack while the laminating process is complete.

ESA on Plastic Parts Application Sheet

          Plastic parts when stored in a collection container, typically after injection moulding will carry a static charge. Although the charge on each individual part may be low, the accumulative charge will be very high. A small moulding may have only 10v of static electricity on it?s surface, but if you add another 10,000 parts to the collection, you now have an electro-magnetic field generated by 100,000v of static electric?ty.This electro-magnetic field will attract airborne contamination and other dust and dirt particles onto the product creating rejects and down time for cleaning.The electro-magnetic field can also be absorbed into the bodies of operators working within close proximity. The operators will discharge when they come into contact with an earth potential such as a machine casing, door handle or even another operator. Although the shock can be painful, it is seldom dangerous. The major concern is the ?nvoulantry reaction to the shock which can be dangerous if working closely to moving or running machinery..

        By positioning a PULS Electronic Pulse DC ionising bar above the collection container, you will have a steady stream of ionised air bathing the products, eliminating the static charge and preventing attraction of contamination. This will also remove the electro-magnetic field which causes the discharge shocks for operators.

Multi Head Labelling Machine Application Sheet

        Labels can be misaligned or repelled from charged bottles due to large static charges which are generated as the bottles move through conveyor systems. The bottles encounter high levels of friction which charge them. When the bottles are positioned to have the label fitted, the static charge on the bottle, as well as the charge on the label (generated as the backing tape is removed) can cause the labels to repel from the bottles. This causes waste, rejects and down time.

        By positioning either a PULS Electronic blower or bar to the conveyor prior to the label application, you can bathe the bottles in ionised air and eliminate the possibility of rejects, improving quality, productivity and profits.

Contamination on Plastic Parts Application Sheet

 

        After moulding, many plastic parts have further manufacturing process to go through prior to packing and shipping. If parts are to be painted, the high levels of static which are generated in the moulding process attract dust, dirt and other airborne contamination on to them. If the parts are not cleaned, the high levels of inclusions create re-work or rejects.

        

        By bathing the product ?n ionised air you will eliminate the static charge that is attracting the contamination onto it. The PULS Electronic Ionising Blower is specifically designed to cover a large area with ionised air. Resulting in fewer inclusions, fewer rejects and higher productivity.

Chocolate Manufacture

        Two different colours of chocolate are injected into the mold as shown in the figure. If these two products have the same static charges, they push each other and if they have the opposite static charges, It causes form changing of the chocolate. In addition to these problems, they attracts dust so it isn?t an acceptable condition. It may cause electrical shocks and because of the carrying problems, the speed of the system decreases.

        

       H&O static bars positioned as shown will neutralise static charges on the moulds and layers of chocolate.

Electronic Weigher Static Application

         Static charges on a weigher cause some problems like unpleasant operator?s shocks, data and indicator errors, fault weight of the material and changing weight of the material. Because, dust and particules adding to the material change the weight if you use labratory weigher.
If H&O Antistatic bars are positioned to the right place, they provide effective ionization. Therefore, when the products are put onto the weigher, the bars neutralize them. 

Plastic Bottle Conveyor Lines Application Sheet

        As PET bottles travel at high speed along conveyor lines the friction generates high levels of static electricity. If they spark to earth, the omitted radio wave can affect electrical circuits and metal detectors. It is also possible that as the bottles are being charged to the same polarity, they will repel from each other and jump off the conveyor into the air.

       

        By positioning a PULS Electronic Pulse DC Bar along a section of the conveyor, you can discharge the bottles safely ensuring no discharges to earth that will affect any electrical circuits, PCBs or metal detectors.
