Definitions

  • the invention relates to a device for producing packs from sealable and / or weldable or adhesive films with at least one film transport device and with devices for molding and / or filling and / or closing and / or separating the packs and the film transport device preferably has a horizontally lying frame, which can be moved back and forth by means of a motor-driven crank and a push rod, and this frame additionally carries the devices for shaping and / or filling and the like.
  • Such a device is known from US Pat. No. 4,048,782.
  • the horizontally lying frame is slidably mounted on a machine frame at table height and is moved back and forth during operation of the device by a motor-driven crank mechanism.
  • the frame is supported by vertical swing arms on which a push rod of the crank mechanism engages. All of the stations that form the films to be processed are stored on this frame, possibly filling the film trough that holds the contents, fumigating or evacuating, sealing and sealing or gluing the packaging, and finally the packages, which are usually in rows and rows, in individual packages separate.
  • the frame also carries drivers and grippers, which pull the foils off of supply rolls and transport them when the frame goes back and forth, ie move them relative to the frame itself.
  • these drivers and grippers are designed as rollers or roller disks arranged in pairs, between which the foils pass.
  • These rollers are rotatably mounted on the frame and are operatively connected to the reciprocating frame via a one-way clutch in such a way that when the frame is moved in one direction the rollers rotate and thereby cause the transport of the foils against the frame, whereas when the frame moves in the other direction, the rollers are standing, so that the frame and film do not move or move during this movement of the frame relative to each other.
  • the film and frame are at rest during that work cycle, during which the films are each shaped, filled, possibly fumigated and evacuated, sealed, glued and sealed. These operations require a certain amount of time, which cannot be reduced at will. This time period is the same as the one sliding movement of the frame relative to the machine frame.
  • FIG. 1 shows from the side and schematically a device of the type in question for producing packs from foils;
  • Fig. 2 shows the drive for the frame in an oblique view and Fig. 3 parts of the drive shown in Fig. 2 in the manner of an exploded view.
  • the device has a fixed machine frame 1 of table height, on which the horizontally lying frame 2 can be pushed back and forth in its plane.
  • this frame 2 is supported by four vertical swing arms 3, which are connected to the frame 2 as well as to the lower horizontal bar 4 of the machine frame 1 in a hinge-like manner.
  • the frame 2 could also be mounted horizontally displaceably on guides in the manner of a slide or a carriage.
  • a push rod 5 is articulated on one of the swing arms 3 and periodically moves these swing arms 3 and thus the frame 2 back and forth via a crank mechanism, which will be explained in detail below.
  • a motor 6 with a pulley 7 and a V-belt 8 drives this crank mechanism.
  • the individual stations are now arranged on the above-mentioned frame 2, namely, for example, a forming station 9 in which the film is deep-drawn to form a packaging tray, a filling station 10 at which the packaged goods are introduced into the molded tray and a closing station 11, in which a lid film is applied to the filled packaging tray and welded or glued to it.
  • the design of these individual stations is of no particular importance for the present invention, so that it will not be discussed in more detail here.
  • other stations can also be arranged on this frame, which are for the Fer of the package, for which it is important to fill and the like and may be required.
  • the processing and processing stations 9, 10 and 11 mentioned are each attached to supports 25 and 26, which in turn are connected to the frame 2.
  • the film feed 12 is provided in the form of rollers or roller disks 13 and 14 arranged in pairs, as is the cutting device 15, which separates the molded and finished packages.
  • the rollers or roller disks 13 and 14 causing the film advance or transport are in operative connection with the reciprocating movement of the frame 2 in such a way that when the frame 2 moves to the left (FIG. 1), these rollers rotate and while pulling the film opposite the frame 2 to the right (Fig. 1).
  • FIG. 1 the frame 2 moves to the left
  • Fig. 1 the frame 2 moves to the right
  • FIG. 2 The drive for the push rod 5 and thus for the frame 2 is shown in FIG. 2 in an oblique view and on a scale that is considerably enlarged compared to FIG. 1.
  • the two in 1 drawing and the frame 2 supporting swing arms 3 are connected to each other with a cross bar 27 and on this cross bar 27, the push rod 5 is articulated, which is connected at its other end to a crank 28.
  • a longitudinal slot 29 running radially in this crank 28, the effective crank arm length can be set, which is decisive for the stroke of the push rod 5.
  • the crank 28 is connected to the fixed, rotatably mounted shaft 30.
  • the bearings carrying this shaft 30 are not shown for reasons of clarity.
  • a pulley 31 and an eccentric 32 are also provided on this shaft 30.
  • the eccentric 32 is designed so that it can be adjusted and adjusted in its angular position relative to the crank 28.
  • Another stationary axle 33 is mounted parallel to the shaft 30 of the crank 28.
  • the bearing blocks bearing this axis 33 are not shown for reasons of clarity.
  • the pulley 34 is rotatably mounted on this axis 33 and is driven via the V-belt 8 and the pulley 7 seated on the output shaft of the motor 6.
  • a shaft 35 lying parallel to both the axis 33 and the shaft 30 is freely rotatably supported in this disk 35, said shaft 35 projecting beyond the disk 34 on both sides.
  • a pinion 36 and 37 is firmly wedged with this shaft.
  • a hollow shaft 38 through which this axle 33 passes, is supported, which carries at one end a crank arm 39 which is connected to the eccentric 32 of the shaft 30 via an eccentric rod 40 .
  • the hollow shaft 38 carries a pinion 41 which is connected to the pinion 36 in a rotationally fixed manner via a belt (toothed belt 42).
  • the arrangement can of course also be designed in such a way that crank arm 39 and pinion 41 are in direct contact with one another without these two parts a hollow shaft is arranged in the sense of the illustration shown.
  • non-rotatable connection is understood to mean a connection between two pinions, disks, shafts or cranks, which transmits the rotary movement of one part to the other, this being possible by means of belts, toothed belts, chains, gear wheels or the like.
  • a countershaft with the same axle 33 which here consists of the hollow shaft 43 with the two pulleys 44 and 45, which have different diameters.
  • the small pulley 44 is connected in a rotationally fixed manner via a toothed belt 46 to the pinion 37 on the shaft 35, the large pulley 45 via a V-belt 47 to the pulley 31 on the shaft 30 of the crank 28.
  • the parts described here with reference to FIG. 2 are shown again in Fig. 3 and in the manner of an exploded view.
  • the device acts as if the countershaft 44 - 43 - 45 in connection with the toothed belt 46 and the pinion 37 were rigid would be crank, which is driven via the V-belt 8 at a constant angular speed and which, with the same size of the pulleys 31 and 45, is transmitted unchanged to the shaft 30 and thus to the crank 28, with the result that the crank 28 moves with constant angular velocity rotates.
  • the eccentric 32 has an eccentricity which deviates from zero
  • the crank arm 39 is moved from an imaginary center position once clockwise and once during a full revolution of the crank 28 via this eccentric 32 and the periodically oscillating eccentric rod 40 Deflected clockwise, a process that is repeated periodically due to the constant rotation of the shaft 30.
  • the extent of this adjustment of the crank arm 39 is dependent on the extent of the eccentric 32 and on the effective length of the crank arm 39, that is, on the radial distance of the articulation point 48 of the eccentric rod 40 on the crank arm 39.
  • crank 28 that the eccentric 32 must be positioned radially with respect to the crank 28 results from the above explanations.
  • the extent of the acceleration or deceleration to be superimposed results from the gear ratio of the eccentric and the size of the individual drive and drive disks or wheels.
  • chain drives or gears can be used to transmit the rotary movement instead of belts and toothed belts.
  • a crank can also be provided, which has the shaft 35 at its free end carries and the crank can then be connected to a drive pulley or a drive pinion.
  • the two pulleys 44 - 45 - or the pinion 41 and the crank arm 39 can also be connected to one another directly, that is to say without the interposition of a hollow shaft 43 or 38.
