Form coil bandaging

The machine can be used economically for both series production and repair operations. Looping coils up to a length of 1.5m can be bandaged. Longer coils are possible upon request.  In this system, the belt head is designed with three slip-on roller systems. It is therefore possible to apply up to three tapes to the spool at the same time. In addition, the bandaging head is positioned on a rotary table. The rotation of the bandaging head is 310°, which allows the complete banding of the coil. It is transported through the tape head using a spool guide and bandaged in the curves by rotating the tape head through 180° into the curve. The other leg of the coil is then transported in the opposite direction and also bandaged.  Integrated band headrests prevent bandaging vibrations during the insulation process and thus enable an exact wrapping pattern. The belt advances continuously. Thanks to the electronic speed control, the continuously adjustable taping speed can be optimally adapted to the working conditions. The tape head is controlled via a PLC control with a servo motor controller. In order to achieve simplified and clearer programming operation, the control panel is equipped with a touchscreen display.  To ensure general safety regulations, the winding system can optionally be supplied with a safety fence, light barriers or light scanners.

The feed and winding drives can be controlled independently of each other via the control panel for positioning tasks or loading processes in the tipping area.
Using a presettable counter, the machine is automatically stopped once the required tape length has been reached. The newly developed magazines are designed with a locking system that can be opened without additional tools. The handling is very ergonomic and after a short training period, the machine can be operated quickly and productively.

The banding head can be moved outwards from its position or adjusted to the center of the coil. This makes it easier to adjust the band head to the core diameter. In order to ensure a uniform winding pattern for the different core and body geometries, the machines are equipped with 2 driven, adjustable feed rollers. The desired percentage overlap is achieved manually using the feed support on the adjustable banding table. The feed is stepless and can also be corrected during bandaging.

A stationary head with 2 bands and a movable head with 3 bands. Both heads are mounted on an electronic turntable, with the second bandaging head also being linearly movable using a servo motor. This ensures precise head positioning for different needle lengths and guarantees a flawless bandaging process

The BD-LP 3000 is equipped with a taping head that is positioned on a rotary table. The tape feed is stepless. The electronic speed control allows the stepless adjustable taping speed to be optimally adapted to the working conditions. The needle is transported through the tape head using a needle guide and simultaneously taped by swiveling the tape head up to the needle curve. The other leg of the needle is then transported in the opposite direction and taped in the same way. The tape head is controlled by a PLC with a servo motor controller. To achieve simplified and clearer programming, the control panel is equipped with a touchscreen display.

The tape feed is stepless. By using four axes driven by servo motors, all horizontal coil geometries (straight lines, corners and curves) can be moved within a large working area. According to the previously programmed coil contour, the taping process runs in a fully automatic cycle, controlled by a PLC. The tape tension is set to the tape material used and the required insulation quality. The tape head is transported through the needle coil using guide elements. The linear transport and rotation of the taping head automatically produce the protective or base bandage of the needle coil. Integrated tape head supports prevent the banding vibrations that occur during the insulation process and thus enable an exact winding pattern. In order to achieve simplified and clearer operation of the programming, the control panel is equipped with a touchscreen display. To ensure general safety regulations, the winding system can optionally be supplied with a safety fence, light barriers or light scanners. The system can be used for both series production and repair operations.

The insulating head takes two supply rolls, which realize a sufficiently adjustable, diameter-independent tape tension. Two pneumatic clamping points are used to take up the wound body, one fixed being connected to the steel frame, but the second being designed to be adjustable according to the body length to be wound. On the steel frame there is a support surface for holding the loop coil with a max. Length of 3000mm. The working area of the machine is secured with a protective hood. Furthermore, a diameter-independent, constant belt tension can be set. Insulation is possible in both directions and the number of insulating layers is freely programmable. In addition, the speed of the winding ring can be freely selected. In addition, the tension of the outputs to be wound up can be set up to 500 N.

An electronic counter and an automatic tape cutter are standard. The magazine speed is controlled by a foot pedal, whereby the operator must guide the spool manually. The tape is simultaneously filled into the magazine and wound directly onto the spool body. The compensation slide, which is integrated in the magazine, compensates for the tape length differences per revolution.

The taping head enables the tape rolls to be changed quickly and has an open design. The forming rod automatically runs through the programmed taping directions using two support rollers.
The taping head is driven by a three-phase motor. The electronic speed control and reversal of the direction of rotation allow the taping process to be optimally adapted to the working conditions (for example for conical taping attachments and outlets). The table surface is also the winding level for the forming coils.

Various paper, plastic and fabric tapes with a width of 15 – 25 mm as well as other suitable tapes can be processed. The machine is equipped with a continuously electronically adjustable AC drive. The feed drive is electronically coupled. The mechanical support of the hand guide is preset using a continuously variable gear.

As with all machines in the BMF series, it is characterized by a very robust construction and easy operation. The driven feed rollers support the manual guidance of the wound goods. The electrically controlled feed ensures precise overlap. The taping head enables the tape rolls to be changed quickly. It has an open design. Various paper, plastic and fabric tapes with a width of 10 – 30 mm as well as other suitable tapes can be processed.

With the manual guidance supported by the mechanical feed, it is possible to bandage even complicated bodies effectively. The special design of the table top allows maximum flexibility, even for large, irregular bodies. The machine is equipped with a continuously electronically adjustable AC drive. The feed drive is electronically coupled. The mechanical support of the manual guidance is preset using a continuously variable gear.

It can be used to process all common insulating tapes. The insulation process runs automatically, controlled by the PLC, according to the previously programmed coil contour. This means that any program that has been programmed once can be called up again at any time. This means that there is no need to teach the contours again.
To make programming easier and clearer, the control panel has been equipped with a touchscreen display.
The taping speed is infinitely variable and the tape winding head can be regulated in the braking system.

In addition to the tape head supports, the system is also equipped with a newly developed, automatically adjustable spool support system, which means that the system runs very smoothly even at high speeds. This ensures an exact winding pattern during the taping process. The system is automated using a 6-axis control system. After the spool contours have been taught, the entire winding process of both legs, including the swiveling of the spool, is controlled electronically.
All winding parameters (teach-in process) are entered via a display operator interface and can be corrected at any time. A PLC in conjunction with a plain text display takes over all control functions. To ensure personal protection during the system’s ongoing taping operation, laser protection devices are integrated in the machine’s working area.

Up to 2 strips can be processed at the same time, even of different strip qualities.
By using six servo-controlled axes, almost all bar geometries can be insulated in a large to very large working area. By clamping it in 2 end supports, the shaped bar is positioned lengthwise for insulation. The winding head, in which the winding ring with the two braked supply spools rotates, is pivoted on a machine body so that it can rotate about the vertical axis. During the insulation process, the winding ring moves transversely in the swivel arm and tilts in the swivel range according to the pre-programmed contour. The control is via a process PLC with a real-time capable multitasking operating system. The operator is guided via an operating panel, i.e. functions are called up via menus on the screen. The coil contour is recorded using a “teach-in” process.

Mittels des Luftkissenprinzips passen sich die Stützen jeglicher zu bewickelnden Körperkontur an (6-Achs-System), und bieten gleichzeitig einen stabilen Halt des Körpers beim laufenden Wickelprozess. Zusätzlich ist der Bandagierkopf mit einem pneumatisch zustellbaren Kopfstützsystem ausgestattet, wodurch sich die Anlage auch bei hohen Geschwindigkeiten durch einen sehr ruhigen Lauf auszeichnet. Durch die Kombination aller elektronisch gesteuerten Stützen wird beim Bandagiervorgang ein exaktes Wickelbild realisiert. Durch eine elektronische Drehzahlregelung ist die Wickelgeschwindigkeit stufenlos und somit den jeweiligen Arbeitsbedingungen optimal anzupassen. Sämtliche Wickelparameter (Teach-In-Verfahren) werden über eine Display-Bedienerführung eingegeben und sind jederzeit korrigierbar. Eine SPS in Verbindung mit einer Klartextanzeige übernimmt sämtliche Steuerfunktionen.
