The Vipromat Integral is a rather young addition to the Viprotech screen printing machine programming. Based on the Vipromat Executive, the Vipromat Integral is a very versatile three-quarter automatic screen printing machine equipped with an integrated take-off system and a conveyor belt. The take-off system is fitted with four suction units which can slide sideways to fit any material size. Each suction unit has a 21 or 15 mm mark free silicone suction cup that can be individually switched on or off. All the adjustments to the take-off system can be made quickly and are tool free. The waiting position of the take-off just under the rear part of the top frame contributes to fast cycle times. Functions like the variable take-off speed and vacuum delay allows even materials that are difficult to handle to be processed without trouble. The speed of the continuously running conveyor belt can be adjusted between 5 and 25 m/min. and delivers the printed substrate to your adjacent dryer. The conveyor belt starts directly behind the printing table making this machine very compact.
The Vipromat Integral owes it success mostly for its flexibility, operator friendliness and the fact that the well known and proven Vipromat Executive has been the basis on which the Integral was designed. As a result, most of the characteristics and specifications of the Vipromat Executive, including the available options (with the exception of the machine dimensions), apply to the Vipromat Integral as well.
Within the Vipromat family, the Vipromat Integral is one of four available models. Two models, the basic Vipromat Standard and more sophisticated Vipromat Executive are semi-automatic machines. Top of the range is the three-quarter automatic Vipromat Inline Cool which also incorporates a UV dryer and stacker. Click here to see the differences between the four models.
The Vipromat is equipped with a state-of-the-art micro controller (control panel), providing all necessary information in clear text (English, French, German, Spanish, Slovenian or Dutch). The majority of the machine settings can be made directly from the control panel on which all functions are illustrated by easy to understand icons. Pressing a key first explains the function in clear text together with the current state or setting (on, off, time or speed setting etc.). This makes the machine very user friendly, even when the printer does not operate this particular machine every day.
Many relevant job settings can be read from the text display. When a print job returns the operator can setup the machine quickly and produce identical printing results.
The machine printing cycle starts automatically (adjustable feed timer) or by pressing the foot pedal (not shown on picture). Pressing the foot pedal during the machine cycle will finish the current action and then stops the machine. This allows the operator to check the printing result with the screen and squeegee down and to make fine adjustments fast and safely.
The printing head lifting arms are placed so far back that the operator has full access to the whole printing area not only from the front, but from both side as well. This, together with the large opening of the print head, makes handling materials underneath the screen very easy.
Little effort is needed to slide the screen into the machine from the left or right side and the screen may even extend somewhat during printing. This allows more same-color-jobs to be exposed into a single screen and just re-position the screen to print the next job, thus saving time and money again.
Another important advantage is that during cleaning and removing ink, the screen may extend the machine largely which makes it accessible from three sides: top as well as bottom and from outside the machine.
The front screen bar is fixed whilst the rear screen bar can be moved forward to fit any smaller screen size. Subsequently, smaller screens always start at the front, close to the operator’s eyes.
A pneumatic locking system secures the screen into the screen holder bars, reducing time needed to unlock and lock the screens manually. The screen remains locked when power to the machine is switched off.
Uniquely to the Vipromat, this machine prints from front to rear, allowing the operator to see the separation of the mesh from the substrate, printing force distribution etc. Printing like this enables the operator to actually see the image being transferred to the substrate.
An integrated peel-off system lifts the screen at the front during the whole print stroke (front to back), effectively separating the mesh from the printed substrate. The peel-off stroke can be adjusted (limited) or set to zero.
Independent adjustable squeegee and floodcoater speed with digital speed read-out directly from the control panel. The speed can be set between 0.2 and 1.2 meter per second.
The Vipromat is equipped with a pneumatic squeegee and floodcoater change-over system.
Besides a well functioning pneumatic squeegee pressure equalizer system, the operator can choose to deploy the conventional mechanical squeegee pressure system. Both systems are available to the printer. Using the pneumatic system, the operator does not have to re-adjust the squeegee after intermediate sharpening or small changes in squeegee angle. The pneumatic equalizer system continuously adjusts the squeegee pressure across the printing width during printing.
Mechanical adjusters on the squeegee carriage for squeegee pressure and floodcoater height.
Choice of flooding directly after the print stroke (print-flood) to increase the production speed and avoid solvent based ink to dry in the screen or flooding just before the next squeegee stroke (flood-print) to avoid ink seeping through the mesh when printing e.g. a negative image.
Multiple print function allows the same substrate to be printed up to 5 times.
An adjustable peel-off timer allows a delay to be set between finishing the squeegee stroke and the lifting of the print head to allow more time for the mesh to separate from the substrate (e.g. when printing a negative image or using high viscosity inks).
An operator resetable production counter keeps track of the number of printed substrates.
Sliding optical proximity switches on the print head allow an adjustable print stroke length.
The squeegee carriage runs over a hardened linear guiding rail to guarantee a vibration free motion.
The Vipromat Integral accepts A type (30mm bar) squeegee and floodcoater. Only the Vipromat Integral 1000×1400 has a B type (40mm bar) squeegee and floodcoater.
The Vipromat has a durable, hard wearing, thick skin aluminum printing table. The extra dense internal honeycomb gives the table its exceptional flatness and rigidity.
Substrates are sucked down onto the table from the center out, flattening the substrate towards its edges. Possible wrinkles are effectively flattened out before printing starts.
The Vipromat is equipped with a very powerful yet silent vacuum motor.
Especially for printing porous materials a pre-vacuum time can be set allowing more time for the substrate to secure to the printing table before printing.
Blow-back assists the lifting of heavier or (light) static materials after printing to simplify take-off.
Controlled vacuum timing avoids statically charged substrates to stick to the mesh when the screen is lifted after printing.
Accurate screen register is obtained by moving the printing table in the solid machine chassis rather than the screen itself in the print head. For this purpose the table can be positioned accurately with three play-free micro adjusters for X and Y direction and rotation (theta).
The off-contact can be adjusted at all four corners of the printing table simultaneously with a light running hand wheel located at the front left corner of the Vipromat. The off-contact can be set between 3 and 28 mm.
After printing, the take-off carriage will start to move forward over the printing table as soon as the print head opens only half way. The pick-up position on the printing table can be accurately set by a sliding proximity switch located on the left side of the printing table. The take-off and has a repeatability better than ±2 mm. This means that one can work with a minimum sucker margin of less than 25 mm for a 21 mm suction cup and 20 mm for a 15 mm suction cup (optional).
The take-off carriage has 4 suction units. These suction units can be positioned over the width of the take-off carriage to fit any substrate size. Two suction units will provide ample of holding force to pick-up even heavier substrates. Nevertheless 4 suction units are supplied so that relatively light but flexible materials are well enough supported over the length. Due to the special shape and composition of the suction cups, no creases or cup marks are left on the substrate despite the strong holding force.
The take-off carriage can be positioned an additional ±10 cm forward, enabling the printer to feed even small substrates close to the front of the printing table.
After pick-up of the substrate, the take-off carriage will run quickly to the rear of the conveyor belt and release the substrate to drop onto the running belt. After that, the take-off carriage runs quietly to a waiting position under the print head close to the rear of the screen while the next printing cycle is made.
A high quality UV-resistant Teflon® coated glass fiber mesh belt conveys the printed substrate towards e.g. an adjacent dryer. The color of the belt is black and so is the metal work under and around the belt. Black absorbs the most visible light and UV-radiation that could be escaping from an adjacent UV-dryer inlet.
The speed of the conveyor belt can step less adjusted between 5 to 25 meter per minute and is displayed digitally on the control panel.
The Vipromat is equipped with an emergency stop bar around the front, left and right side of the print head as well as an emergency push button to stop the machine immediately. The print head lifting mechanism is constructed in such way that the print head is not pulled down with force when something is obstructing while closing.
With close to 1.000 units installed in 25 years, the Vipromat belongs to the best sold and most rewarded screen printing machines in the world.
Due to the user friendliness and simplicity of operation, compact construction and well though-out design, the setup for printing and job changes can be made in record time.
The Vipromat runs on a common 230V, 50Hz single phase electrical connection. There is no need to connect the machine to an industrial 3-phase power connection. An air compressor is required.
The machine comes with a full set of documentation as well as a squeegee and floodcoater for the maximum print width.
