Definitions
- a method and apparatus for forming parallelepipedic packages from a continuous length of tubular material comprises a pair of mold halves which square up the tubular material into a rectangular configuration, a pair of pressing jaws coordinated with the mold halves which form a transverse seal and effect a primary advance of the package material between the mold halves, and a pair of folding flaps which function to flat-press triangular flaps projecting from both sides of the package body and also serve to effect a secondary advance of the package material, the extent of this secondary advance being determined by the amount of movement imparted to the folding flaps and being adjustable to ensure proper placement of printing or other indicia on the package material in relation to the package being formed.
- the present invention refers to a method or registering ornamentation, creases, stamped holes or the like in manufacturing packages of a tubular material.
- the invention starts from well-known methods of manufacturing packages by fiat-pressing and sealing in relatively narrow zones transverse in relation to the tube axis and spaced along the latter, the individual packages being detached from each other by transverse cuts in the sealing zones.
- the object of the present invention is to register ornamentation, stamped holes, creases or the like with which the starting material for the abovementioned method of packaging is provided. This is attained according to the invention by bringing about the advance of the tube material in two steps, the length of the last step being made dependent on whether an indication mark provided on 3,417,674 Patented Dec. 24, 1968 each or certain of the package units has passed a sensing member.
- the invention is intended to be practiced in manufacturing parallelepipedic packages in a corresponding shaped mold with simultaneous axial upsetting of one or both end surfaces of the package, triangular, projecting flaps being formed at these end surfaces.
- the second advance step may then be performed by flat-pressing of said flaps, the length of said second step adjusted by flaps belonging to dilferent packages being pressed flap to varying extents.
- the invention also refers to a device for carrying out the method described above, including main advancing means for advancing a tubular material, pressing jaws for flat-pressing and sealing the tubular material in relatively narrow zones transverse in relation to the tube axis and spaced along the latter, and cutting means for detaching the individual packages from each other by transverse cuts in the sealing zones, this device being characterized by secondary advancing means for providing a second advancing step, the length of which is dependent on whether an indication mark provided on each or certain of the packages has passed a sensing member belonging to the device.
- FIG. 1 shows diagrammatically a device for manufacturing a square section package.
- FIGS. 2 and 3 show in section and on an enlarged scale a detail from FIG. 1 in various positions.
- FIG. 4 shows diagrammatically the operating means for the detail shown in FIGS. 2 and 3.
- FIGS. 5 and 6 finally show how certain details of the operating means according to FIG. 4 may be designed in practice.
- a tube 1 is fed in between two mold halves 2 and 3 which give the tube a rectangular cross-section.
- the mold halves cooperate with two folding flaps 4 only one of which is shown in FIG. 1 and which are mounted on axles 5.
- These details cooperate furthermore with two pressing jaws 6 and 7 in such a way that the bottom of the finished package 8 is upset to be essentially fiat while forming triangular flaps 9 and a transverse seal 10, the flaps 9 being intended at a later operating stage to be folded up against the package side, whereupon the transverse seal 10 is folded up against the package bottom.
- two sets of mold halves, folding flaps and pressing jaws operate alternately. In order to illustrate the invention, however, it has been considered suflicient to show only one set in FIG. 1.
- a first advance step is provided by the pressing jaws 6 and 7 being arranged to pull the tube 1 forward.
- the second advance step of the tube is then produced by shifting the folding flap initially positioned at 4' to the position designated by 4 in FIG. 2, which produces a flat-pressing of the underlying triangular flap 9 also causing the tube to be pulled forward again. If then only a slightly less second advance step is required the folding flap is folded inwards only to the position designated by 4 in FIG. 3. In practice it has been found that the angle designated by a in FIG. 3, substantially influences the advance distance at the same time as it has a quite negligible influence on the volume of the finished package.
- FIG. 4 it shows diagrammatically, by way of example, the operating means for the folding flaps 4 which are stationary in relation to the halves 2 and 3 (not shown in FIG. 4).
- Non-rotatably mounted in relation to the folding flaps on the same axles are two eccentric arms 11 the free ends of which are in engagement by means of pins 12 with actuating arms 13 on a draw rod 14.
- the details 45 and 11-14 shown in FIG. 4 are mounted movable together with the mold halves 2 and 3 and the pressing jaws 6 and 7 in the direction of the arrow A, i.e., in the tube feeding direction, the second advance step being produced by the engagement of the guide roll 15 mounted on the draw-rod 14 in a groove 16 in a guide cam unit 17.
- the guide cam unit 17 is movable laterally in the direction of of the arrow B. This movement is produced by the unit 17 being provided with projections 18 which are mounted on bell-crank levers 19 which in turn are mounted at fixed points in the machine frame on pivots 20. By means of further pivots 21 the bell-crank levers 19 are coupled to a second draw-rod 22 which via a link 23 is coupled to a hydraulic cylinder 24. From the above it will be seen that the guide cam unit 17 is displaced in the direction of the arrow B when the piston rod of the hydraulic cylinder is pressed outwards and in the opposite direction when the piston rod is drawn into the hydraulic cylinder. In order to limit this movement in a lateral direction. the draw-rod 22 is provided with a projection 25 with a set screw 26 which is normally arranged to cooperate with a displaceable stop 27 which is inserted between the set screw 26 and a stationary stop 28a.
- second stationary stop 28 which is adapted to cooperate with the other end of the set screw 26. If the set screw 26 is held pressed against second stop 28b the folding fiaps 4 are caused to carry out complete angular movement, i.e. the flaps 9 are pressed completely fiat.
- the adjustment is such that the advance step obtained by the flat-pressing will be slightly greater than is required for providing exact registration.
- the hydraulic cylinder 24 receives an impulse, so that the set screw 26 is instead pressed against the stop 27.
- the guide unit 17 is moved in a direction opposite to the arrow B, which causes the folding flaps 4 to press the triangular flaps 9 only incompletely flat.
- the advance step obtained will be smaller than normally so that the registration is changed in the desired direction.
- the stop 27 is removed.
- it is attached to the piston rod 29 of a second hydraulic cylinder 30.
- Such greater adjustments may be suitable for example in the case of exchange of splicing of the tube web material.
- FIGS. and 6 show how certain details of the operating means shown in FIG. 4 may be designed in practice. Because the details generally coincide with those described above the same reference numerals as in FIG. 4, have used, although with the addition of a letter. Thus, the folding flaps have been designated by 412 and the pivots thereof by 5a. Furthermore, the eccentrics corresponding to the eccentric arms 11 have been designated by 11a and the pivots and sliding blocks, corresponding to the pivots 12, have been designated by 12a and 12b, respectively. In the same manner actuating arms cooperating with said sliding blocks 12b have been designated by 1311. The greatest difference in relation to the device shown in FIG.
- the two hydraulic cylinders 24 and 30 may be exchanged for a slide valve having three positions, by means of which the draw-row 22 in the same way as described above may be caused to perform two different strokes for fine and coarse adjustment, respectively.
- the hydraulic cylinders may also be exchanged for pneumatic cylinders.
- a starting material one may use either a seamless tube or a tube which is formed from a fiat web of material in a preceding operating stage.
- the method of producing parallelepipedic packages from a continuous length of tubular packaging material which includes indicia such as printing thereon repeated at spaced intervals along said material corresponding to the length of the successive packages to be formed which comprises the steps of advancing and shaping a length of said tubular material to the desired side wall rectangular configuration simultaneously with upsetting the end portions of said length of material to form flattened ends of the package including triangular end flaps projecting laterally of said ends, and thereafter pressing said triangular end flaps towards a flattened state to effect a corresponding supplementary advance of said shaped tubular material, the degree of flattening of said end flaps being determined by the position of said indicia on said material in relation to a stationary sensing member.
- Apparatus for producing parallelepipedic packages from a continuous length of tubular packaging material which includes indicia such as printing thereon repeated at spaced intervals along said material corresponding to the length of the successive packages to be formed which comprises cooperating jaw means for advancing and shaping a length of said material to the desired side wall configuration simultaneously with upsetting the end portions of said length of material to form flattened ends of the package including triangular end flaps projecting laterally of said ends, a pair of pivotally mounted flap folding members for pressing said triangular end flaps and to simultaneously effect a comparatively minor and supplemental advance of said material depending upon the magnitude of the angular movement of said flap folding members, and means controlling the angular movement of said flap folding members in accordance with the position of said indicia on said material in relation to a stationary sensing member.
- each of said flap folding members includes two adjacent faces forming a right angle, one of said faces in the case of a maximum angular movement of said members abutting the corresponding side of the package and the other face abutting the upper surface of the corresponding triangular end flap.
- Apparatus as defined in claim 4 wherein said arms for actuating said flaps folding members and said draw rod together with said jaw means for advancing and shaping a length of said material into package form are mounted for movement together as a unit, an end of said draw rod being arranged to come into contact with and be guided by a guide cam during movement of said unit, the extent of the angular movement of said flap folding members being determined by a movement of said guide cam in the operating direction of said draw rod.
