Definitions

  • the subject-matter of the invention is a device and method for label processing, in particular being a module for hot stamping and decorating labels.
  • the field of the invention relates to the automation of production processes.
  • Hot stamping modules are designed to improve the quality and aesthetics of labels by applying metallised foil to their surface. They are mainly used in the printing industry to produce labels for products such as packagings, food products, cosmetics and chemicals.
  • EP3150367 discloses an invention being an apparatus for processing a flexible material, such as a paper material or a polymer film, in particular in the form of a continuous strip.
  • the apparatus of that invention can be used as a cutting apparatus, in particular for obtaining labels destined to be applied on containers, such as bottles, jars, trays or others besides, to be used in the food, cosmetic sector or the like.
  • the apparatus makes it possible to regulate the relative position of the first roller and the second roller, independently of the pressure with which the rollers are pushed towards one another by the relative pressing device. Owing to the position adjustment device, it is in fact possible to directly regulate the relative position of the first roller and the second roller, without having to act on the pressure applied by the pressing device.
  • the relative position of the first roller and the second roller can therefore be regulated in a more immediate and rapid way with respect to the known apparatus, even by operators having little expertise.
  • EP16725193 discloses an invention which relates to an apparatus and method for cutting, printing or embossing a continuous sheet of material
  • the apparatus provides an improved flexibility to cut, print or emboss with different tool lengths on the tool element, and with an improved speed of production for cutting, printing or embossing.
  • the continuous sheet is arranged to pass between each anvil and the tool element, and the apparatus can be used to implement a continuous process for cutting, printing or embossing of the continuous sheet.
  • the improved speed of production is provided by the constant surface speed of the tool element, which is not required to change speed during operation of the apparatus.
  • the improved flexibility is provided by the phase adjustment device which operates to change the phase of one cut, print or embossing relative to another alternate cut, print or embossing.
  • the continuous sheet is a sheet of material that extends along a certain run within the apparatus, and may be fed into the apparatus from a feed roll. Overall the apparatus may reduce the time, effort, and cost involved from changing from one cutting, printing or embossing task to another. It will be understood that the adjustment of the speed of the continuous sheet within the apparatus using the phase adjustment device may include accelerating or decelerate the speed, and also reversing the direction of travel of the continuous sheet as required.
  • EP3150368 discloses an apparatus for manufacturing discrete portions, the apparatus comprising: - an advancement device for advancing a flexible material along a path; - a cutting device positioned along said path for cutting the flexible material so as to obtain a discrete portion, the cutting device comprising a laser source so configured as to emit a laser beam incident on a rear face, the rear face being opposite a printed front face of the flexible material; - a retaining device, for retaining the flexible material while the cutting device cuts the discrete portion from the flexible material, which comprises a suction belt having a branch facing the cutting device and a conveying portion arranged downstream of the branch, a separation zone being interposed between the branch and the conveying portion for separating a waste material from the discrete portions so that the conveying portion conveys only the discrete portions; - a detachment zone for separating the flexible material from a support layer, the detachment zone being positioned upstream of the cutting device, so that the support layer does not interfere with the cutting device; - wherein
  • the existing solutions which represent devices for processing, cutting, stamping and decorating labels, offer a number of advantages but do not satisfy all the requirements that have been imposed on them.
  • prior art solutions employ the components of a known mechanism comprising two shafts with cams which are responsible for controlling the motion of the lower stamping portion.
  • Such a system does not provide for the automatic control and the precision of the operation of the module, which increases the risk operator errors, causes waste in the label production process and also makes the process more time-consuming.
  • the disadvantage of the existing solutions is also that they need to be calibrated manually and are of low efficiency.
  • the existing solutions also require longer times of manual adjustments and high qualifications held by the operator.
  • the problem is that manual adjustments are not repeatable and the existing set-up cannot be saved and implemented as automatic adjustments. Another issue is that the devices heat significantly while in operation, leading to a risk of burn injuries. The problem is also that it is impossible to collect data for statistical analysis.
  • the objective of the invention is to provide a solution addressing the above problems which exist in the prior art. Moreover, another objective is to limit material losses and costs, increase efficiency and reduce manufacturing time. The objective is also to enable a precise application of metallised foil to the surface of labels. Further, the objective is to improve the quality and efficiency by automatic pressure adjustment. Yet another objective is to reduce time and minimise errors resulting from manual calibration of the depth of the pressing element. Finally, the objective is to respond to market demands around increasing automation and digitisation in the processing of labels.
  • the essence of the solution is a device for label processing, in particular being a module for hot stamping and decorating labels, the device having an immovable block, the block placed in the frame of the module, with servo drives, and at the same time having a head with a foil guiding system, the head placed on the immovable block, with a movable stamping portion placed under the immovable block and seated in the bearing on the shafts with cams, the device characterised in that the main shafts placed in the frame of the module are coupled with the main drive, and the corners of the lower movable portion are adjusted by the adjusting servo drives through worm gears, and at the same time the rotatable head has an unwinding element and a winding element for the foil, at least one head buffer, head guiding rolls and head NIPs driven by head servo drives, and at the same time the immovable block has an upper plate screwed to its underside, said plate with heaters installed, with an upper slidable plate located underneath, said upper slid
  • the head has a head supporting frame and housing and is rotatably seated in the bearing on the immovable block.
  • the position of the cams on the main shafts is adjusted by the adjusting servo drives for adjusting the pressure exerted in the corners and through worm gears.
  • a lower buffer for the decorated material is located under the main shafts, said buffer being controlled at the inlet and outlet of the module with the system with two driven lower rollers and rollers with rubber rolls lower NIPs of the decorated material, wherein the lower servo drives, which drive the rollers, are placed in the housing of the module.
  • the main shafts with cams and the lower buffer for the decorated material are secured by shields in the frame or hinged shields.

  • the rotatable head has at least two head buffers for the foils being passed in parallel, and further systems including shafts and guiding rolls in the head, wherein the head servo drives are coupled with NIPs to synchronise the foil being applied with the material being decorated.
  • the upper aluminium slidable plate can be slid in and slid out under the upper immovable cast-iron block, to which guides with slots are fixed, with the upper aluminium slidable plate being blocked with a catch located in the front of the upper immovable cast-iron block.
  • the glide cubes are made of bronze and fixed in the slots, and the main shafts with cams lift the lower movable cast-iron portion placed in the frame.
  • controllers Preferably, it has controllers, operator's panel and manipulators, switches and controllers to synchronise the web of the decorated material, which are coupled with the sensor detecting the position of the decorated material using markers on the decorated material.
  • the shafts are seated in the bearings in the eccentric mountings placed in the frame and the bearing blocks have bearings.
  • the shafts are fastened with the first driving belt, wherein the main servo drive is connected to one of the main shafts via a further second driving belt.
  • the immovable cast-iron block has, on its underside, guides with slots for the upper aluminium slidable plate with installed dies.
  • the heaters are controlled automatically with feedback from the temperature sensor.
  • the essence is the method for label processing, in particular for decorating the material using the above defined device, comprising the following steps:
  • the advantage of the invention is that automatic control and precise operation of the module are made possible. The risk of errors by the operators and causing waste in the label production process are decreased. The advantage is that material losses and costs are limited. An undoubted advantage is increased efficiency and reduction in time of label processing and with the use of servo drives and process automation, the device is intuitive and minimises the impact of the human factor.
  • the solution of the invention uses servo drives and worm gears.
  • the use of servo drives and worm gears to adjust corners of the lower portion makes it possible to precisely and independently adjust the motion of each one of the corners, as can be seen in Fig. 3-5 .
  • the servo drives and worm gears translate the rotary motion from the servo drives to the linear motion of the corners. This ensures an even and uniform application of the foil.
  • An important feature of this solution is the automation of the hot stamping process.
  • the hot stamping module works without the need for operator intervention which makes the label production process faster, more efficient and repeatable. This translates into an increase in production efficiency and into waste reduction. This makes the hot stamping module a useful tool for various sectors and production lines.
