JDA- How to Set Up a Tamper Evident Neck Bander Machine https://jdaprogress.com/ Neck Bander Machines, Neck band applicators or neck banders are designed to apply a heat-shrinkable film band around the neck of a bottle or container The banding machine is designed to apply a heat shrinkable band to containers. The containers are then transported through a heat source allowing the banding material to shrink and conform to the surface of the container. This is usually for the purpose of tamper-evidence. The material processed through the machine is a tubular material, flattened and wound on a roll sometimes referred to as a roll stock. The material, typically PVC, usually comes wound on a roll in lengths of 500 meters. Because the material is flattened, the machine will have to open the material to apply the bands over an object. For this task we insert a cross-folding device into the material. Then, we set the material with the device inside above a set of rollers, which are closer together than the device is wide. Feeding the individual lengths of material plus the weight of the device and the friction of pulling the material causes the device to interact with the roller removing the original crease from the material. This process will cross fold the material. The material is advanced by 2 opposed rollers, which are driven by either a servo or stepper motor. The rollers create their grip on the material because of the pressure against each other. The amount of rotation by the motor is set at the control panel and will, in effect, cause a specific length of material to be advanced. The banding material is then fed through the cutting mechanism to cut off the individual band from the banding material. Directly below the cutting edge is a vacuum block, which will hold the band in the ready position until a container passes by. To insure that the vacuum block gets a good grip on the band during the cutting process, we use a band retention spring to hold the band against the vacuum block until the band is completely cut. When the spring is removed the individual band will bounce open to a round position. Because the band bounces open so fast, a band-stabilizing finger opposite the vacuum block is used to prevent the band from bouncing around. Above the band is a plunger, which will push the band down when the container sensor detects passage of the container. The band is held at an angle relative to that of the container’s path, such that the downstream portion is lower than the upstream portion. By applying the bands at this angle the band will tend to align itself with the container during application. After the band is applied to the container the process begins all over again until a new band is ready for the next container. The container and band will now be transported through a heat tunnel which will shrink the bands to complete the process.
