Unwind with edge / line guiding and tension control

Controlled unwind guiding

Description: 

Standard adapter bases consist of a stationary floor-mounted frame or plate, a four unit, standard bearing and support system, and a moving frame or plate. A heavy duty servo cylinder is mounted between the frames and the bearings. The servo cylinder moves the upper adapter base plate back and forth in response to hydraulic signals from the power unit. 

Standard adapter base assembly consists of stationery mounted frame, which adopts the existing unwind / rewind stand with shaft and breaks. In the unwind guide, the idler rollers are attached to moving frame before fixed detectors to stabilize web & idle for slitter machines. In the winder guide, the sensor is attached to the moving frame after fixed idler rollers, with sufficient wrap to get perfect winding of material. We can make special kind of rewinding structure where motors also move along with rewinding rolls. 

Applications:

The CON-PAP-TEX adapter base is designed for use in applications where the unwind or rewind stand must be shift able. By fitting the adapter base under the stand, a simple and economical installation is obtained. Because of the relatively high mass of the unwind or rewind rolls, its use is most often found in applications. Where response time can be relatively slow and where accuracies are not overly critical. 

In Rewind guide the detector is attached to the moving frame before fixed idler with sufficient warp to stabilize Web.

In Unwind guide the idler roller attached on moving frame before the fixed detector to stabilize the Web. 

Unwinding:

If the material wound is irregular, this system guide the edge position and let it regularly into the subsequent process. The idler roll moves with the unwinding reel stand. 

·         Mount the detector fixed and as close to the idler roll as possible. 

·         The leaving web formed a angle at the deflector roll should more than 30°. if not possible, apply a pinhole added. The important, do not allow the web slip on this roll. The distance between two rolls should be more than the maximum width of the web.

It is specially designed Aligner for lamination plants. It is very critical and important in modern era to produce minimum wastage and accurate laminates. This is achieved with TWE Chaser Guide. It constantly aligns one of the two web going for lamination and at the same time, keeps taking reference of other web to maintain the web distance constant. This directly results in to minimum trim waste at higher accuracy and production.

An Edge/Line Guide System is a critical component in converting and printing machinery, ensuring that flexible materials such as paper, film, and textiles are fed accurately through processes like slitting, printing, and laminating. By maintaining precise alignment, these systems prevent misfeeds, material waste, and ensure consistent product quality.​

A Load Cell is a type of transducer that is used to convert a force or load into an electrical signal. It is a key component in weighing systems, force measurement devices, and load monitoring applications across industries like manufacturing, logistics, aerospace, and medical fields. Load cells are essential for accurate measurement of weight, force, or pressure in various applications.

1. Sensing Element (Strain Gauges):

   • The most critical part of a load cell. Strain gauges are bonded to the load cell's structure, and they detect small deformations caused by applied force. The strain gauges convert the deformation (strain) into an electrical signal.

2. Structure (Metal Body):

   • Made of materials like aluminum or stainless steel, the load cell's body is designed to undergo deformation under load. The material choice ensures strength and durability for different application requirements.

3. Wheatstone Bridge Circuit:

   • A network of resistors used in most load cells, which allows the small changes in resistance caused by deformation to be measured as changes in voltage. This circuit helps convert mechanical stress into an electrical signal.

4. Excitation Voltage:

   • Load cells require an excitation voltage to produce an output signal. This is usually provided by an external power supply, and the signal generated corresponds to the force or load applied.

5. Output Signal:

   • After detecting strain, the load cell generates an electrical output signal. The magnitude of this signal is proportional to the load applied. This output is often in the form of millivolts (mV) or can be processed into more standard units like volts or digital readings.

1. Strain Gauge Load Cells:

   • The most common type of load cell, using strain gauges to measure the deformation of a material under load. These are used in a wide range of applications due to their accuracy and reliability.

2. Hydraulic Load Cells:

   • These load cells use hydraulic fluid to measure force. The load applied to the cell moves a piston inside, causing a change in pressure. This change is then converted to a force measurement.

3. Pneumatic Load Cells:

   • Similar to hydraulic load cells, pneumatic load cells use air pressure to measure force. These are often used in environments where hydraulic systems are not suitable.

4. Capacitive Load Cells:

   • These use changes in capacitance to measure force. The distance between two plates changes under load, which alters the capacitance, thus providing a measurement of force.

5. Shear Beam Load Cells:

   • These load cells measure force through the shear deformation of a beam or structure. They are commonly used in applications where the load is applied to the middle of the beam and are often used in platform scales.

6. Bending Beam Load Cells:

   • This type works by measuring the deflection (bending) of a beam under load. These are simple and inexpensive and are used in small scale or portable weighing systems.

Pinch Rollers are mechanical components commonly used in various industrial applications, particularly in the printing, textile, packaging, and conveyor systems. The pinch roller assembly plays a crucial role in maintaining tension, guiding material through a process, and ensuring consistent movement along a production line. They are designed to grip and move flexible materials such as paper, fabric, plastic film, or rubber, typically in processes where precise tension control and smooth feeding of material are required.

1. Rollers:

   • The rollers are the primary components of the assembly. Made from rubber, polyurethane, or sometimes metal, the rollers are designed to grip and guide the material. In a typical pinch roller system, at least two rollers are used to create pressure that feeds the material through the system.

   • Drive Rollers: One of the rollers is often powered (driven), providing the force necessary to pull the material through the machine.

   • Idler Rollers: These rollers rotate freely and are typically not powered but work in conjunction with the drive roller to guide the material.

2. Frame:

   • The frame is the structural support that holds all the components in place. It can be made from metal, steel, or other durable materials to provide strength and stability to the entire pinch roller system.

Double and triple power units are available incorporating two and three servo valves on the same reservoir to handle multiple guiding applications. A source of power is mandatory in a web guiding system. The power unit is much more than just an energy source, however, because it normally furnishes modulated power to the actuating devices. It therefore is an amplifier of control signals, as well as a power source In addition to providing hydraulic power for the actuating circuit the power unit produces pneumatic power for the sensors. Sensor supply pressure must remain constant, and the power supply provides this element. Our constant pressure generator produces constant pressure at a given head no pressure regulator is therefore required. Water, oil and scale contamination and other miscellaneous plant air problems are also avoided.
