    about
    ABOUT)
    The invention relates to packaging, in particular, to a device for packaging in film. A device for supplying packing tape material containing a variable speed roller, movable elements for moving the setting material, a photoelectric device for controlling the device G 1 is known. This device only controls the advancement of the tape but does not control its tension. A device is known for packing a product into a thermoplastic tape material, comprising a roll holder, guide rollers of a tape material, a device for controlling the speed of the rollers, a baler, clamping elements mounted for displacement simultaneously in horizontal and vertical directions for feeding the sleeve to a predetermined length. , with the way to control patterns or fold lines 2. A disadvantage of the known devices is that it does not provide accurate adjustment of the position Enjoy the patterns and fold lines on the packaging bag. The purpose of the invention is to improve the accuracy of adjusting the arrangement of the patterns and the fold on the package. To achieve this goal, a device containing a roll holder, guide rollers of a tape material, a device for adjusting the speed of the rollers, a sleeve, clamping elements installed with the possibility of displacement and simultaneously in horizontal and vertical directions for giving the sleeves to a given length, kontrol drawings or folding lines, clamping elements consisting of pairwise swivel sealing elements and folding flap elements having one upper non-operating position There are two working positions, in one of which the grungy elements are completely retracted downwards, and in the other - incompletely, while the hinged elements are associated with a device for checking patterns and fold lines for their drive. 1 shows the proposed device, FIG. 2 is a diagram of the movement of the clamping elements. A packaging device (FIG. 1 contains a roll holder 1, a packaging O material, which may be, for example, paper or cardboard covered with plastic, but more acceptable is a coating containing metal foil, layers of plastic of various types of foamed plastic layers and g. e., depending on the requirements of gas density, grease resistance, etc. Tape 2 has a prefabricated arbitrary finish, and in this case also has cuts in the material intended to facilitate bending. In some cases, the strip of packaging material also has, in particular, a patch in the end zone, printed indications, so that they can be fixed by means of a photovoltaic device (photocell; and the printed marks are made on the strip apart from each other by a packing compartment or several Compartments. In addition, the aforementioned fixed signs are arranged in a constant ratio to the finish and the bend line. To bring the belt 2 into the stretched position, it is passed through the guide rollers 3, after which it passes through the device; arranged in such a way that it can be rotated, and made in the form of a gate, which in this case has a rectangular cross section, and rotates around axis 5. Gate 4 has relatively sharp corner points that can enter into a cross-section grip. The distance of the mehada with the four edges of the gate 4 corresponds to the distance of the cutting lines on the strip of packaging material. The fixture must be connected to the cutting line on the packing material strip; moreover, the cross cutting on the packing material strip should bend around the edges of the gate. Moreover, the transverse cuts on the strip of packaging material must be bent in advance, which provides a significant relief to the subsequent shaping operation. In addition, gate 4 must rotate around the axis of axis 5 synchronously with the transverse cuts, which, in turn, are coordinated with the design of the strip. This means that the angular position of the Eurorota 4 provides a measurement of the position of the cutting line. If the packaging material is elastic, then the gate 4 should be positioned closer to the upper guide roll 6. Instead of the gate 4, you can also use an electric sensor 7 which fixes signs 8 printed on the strip. From gate 4, the strip 2 passes through other guide rollers 3 to the upper guide roller 6. The strip passes through a device 9 intended for applying a sterilizing agent, since the machine here represented is used to package the sterile contents. After that, the strip 2 passes through the upper guide roller b, from where it runs vertically down to the point where it turns into a pipe, this is done by means of a sleeve 10. The contents are introduced into the pipe through the filling tube 11, and the longitudinal edges of the strip 2 are pressed to each other by means of a sealing device 12, through which a pipe with a longitudinal seal is obtained. The filled pipe takes the form of parallelepiped packaging containers 1J. The shaping procedure is that the pair of interconnected Shaping Shutters 14 converge around the pipe, which then bends along longitudinal lines, as a result of which it acquires a rectangular cross section. The compacted lower end of the pipe is then pressed or bent against a flat end wall, this is carried out along the transverse fold line, with the formation of double triangular protrusions, which are pressed against each other using bending plates. When the lower part of the packaging container is formed in this way, the pipe sets and aligns with the forming elements 14 by sealing elements 15, which seal the pipe in a narrow area. At the same time, the sealing clamps 16 are moved inwards and downwards, the flat end wall passes along the shape, and the sealing edge passes along it On which you close with the second pair of formative rock. The upper direction of the roller 6 is driven by the engine at a variable speed. This adjustable motor is driven by pulses, KOTOjMje is output by a collar or photoelectric sensor 7. The principle of regulation is described below. The object of adjustment with the help of the tensioning roller 6 is the tension of part of the strip 2, as well as the pipe. When devices 4 or 7 emit a signal to the drive motor of the guide roller b, its speed increases. This happens when it is necessary to increase the supply of packaging material, while i decreases the mechanical tension of the pipe walls, hence a greater amount of packaging material will advance. Figure 2 shows how a pair of tamping elements are turned inward towards the pipe simultaneously with the vertical downward movement of the pipe together with the shaping flaps 14. The movement of the sealing elements 15 is fully controlled by the cams relative to the downward movement of the shape of the flaps 14, and therefore the sealing grips must always close around the pipe in the same way and with the same movement. This means that all packaging containers should have the same dimensions, since the lower part of the pipe, the bottom part of which has already been formed, is tightly clamped between the four 5 forming doors 14. . the distance between the two sealing zones. Actually, the movement of the sealing grips 15 fully corresponds to the lower shaping flaps 14, but if the pipe tension increases, then there is the possibility, as shown in Fig. 2, of some change in the position of the pipe wall, i.e. the wall of the pipe may become more or less tapered, and the adhesion of the sealing grips 15 to the pipe will not be as neat as when the pipe is in an unsaturated condition, i.e. they will be located more widely. For winding the strip of packaging material 2 from the reel 1, force is required if the upper guide roller b is not driven. However, the force required to drive the entire strip depends on a number of factors, such as, for example, the diameter of the reel 1, the rigidity of the packaging material, its moisture, as well as changing factors, such as friction of guide rollers, etc. Thus, the tension of the pipe may differ in different machines, and may be different for one machine when, for example, the size of the reel 1 changes. This means that a change in the length of the package can be automatically obtained, which increases with increasing pipe tension. If the upper direction of the raklik 6 is not motorized, then these changes in the length of the package must be compensated for using bending plates, i.e. a portion of their adjustment range must be reserved to compensate, for example, a change in the diameter of the reel. Since the shaping elements 16 move relatively faster than the strip, the guide roller must be non-synchronized, so that it can rotate faster than its drive. But at the end of the movement of the shaping elements, the feed rate must be reduced, so the drive motor must rotate again: the guide roller J, providing the force needed to move the packaging material forward,
    The application of the force provided by the upper guide roller is limited by the fact that the driving guide roller once reaches a certain force, slides along the tape 2, therefore the limits within which the upper guide roller can participate in regulating the pipe overlap, From zero to effort, with which causes slippage. It is possible to increase the adjustment range without the use of overrunning clutch on the opposite roller and without driving it at a constant speed. In this case, the tension of the pipe exceeds the value that can be achieved with the passive guide roller, since the guide roller rotates slower than the forming elements are chipped. In this case, a negative force is created, i.e. pipe tension increases. However, when creating a machine of this type, there may be certain difficulties associated with the accelerated movement of the forming element, which leads to the appearance of excessive stresses in the strip and pipe and, therefore, will cause additional
    difficulties in forming a pipe
    Using the guide roller adjuster, you can set the speed range for different types of packaging materials, for example, materials with different stiffness and different coefficients of friction, thereby achieving an appropriate range of control, in fact, the range of control of the speed of rotation of the guide roller depends on performance and feed rates in a packaging machine. As an example, it can be noted that in a machine of the type described above, a circumferential speed of + 35% of the nominal speed of a strip is found to be appropriate for an appropriate control range,
    It is possible to use the belt and pipe tension regulator by itself and to provide regulation by means of a drive of the upper direction of the roller. Suitable for machines. in which a well-known bending shield regulator is used, a combination of systems is used, whereby it is possible to expand the control range without any increase in the so-called spread of the manufactured packages.
