  • the present invention is related to a method and a device to make, of a strip or band like material, corner and edge plates for cases, packings, containers or other receptacles.
  • containers consisting of wood material, e.g., plywood, while the plates and securing tabs thereof consist of a metal.
  • the present invention the object of which is to solve these problems and attain a perfect stamping, striking or forming action notwithstanding a continuous feed of the strip, is substantially characterized in that the strip or band is fed continuously from the supply in that each of the tools are made tomove in the length direction of the strip during a stamping or working operation and to keep pace with the strip at substantially the same speed as that of the strip, and in that the tools after accomplishing their working operation, are returned into their initial position.

  • FIG. 6 a partly cut-out perspective view of a program transmitter device in the plant
  • FIG. 7 A-H fragmentary views of strips worked upon in different working stations.
  • a first stamp, punch or die is generally designated 1, a second stamp 2, a third stamp 3, a fourth stamp 4 and a fifth stamp 5.
  • a supply of strip like material is designated 6 while an equipment for giving a program is designated 7.
  • 8 designates a station for impressing stiffening grooves into the strip and 9 a profile former.
  • 10 is generally designated a forming tool for imparting to the strip bulges of a kind described later.
  • 11 designates a shearing means while 12 designates strips or bands designed to be formed into plates.
  • FIGSv 7 A-H illustrate the different steps of making a plate of a desired shape out of two initially flat, elongate strips.
  • FIG. 7 A shows how the single strips in a first step are imparted groups of securing tabs 13 disposed at a certain spaces, each group comprising a first number actually three of tabs. The groups are in FIG. 7 A designated 13.
  • This first method step is accomplished at the first stamp 1 shown in FIGS. 1 and 2.
  • the next step is undertaken, consisting in imparting to the strips further groups 13 of securing tabs (see FIG. 7 B), each of the new groups I3" comprising a second number of securing tabs, in fact two.
  • the third stamp 3 still further groups 13" (see FIG.
  • FIG. 7 D is illustrated how elongated bores or slots 15 are conveniently stamped out centrally of each of the strips and having the longitudinal direction thereof parallel to the longitudinal direction of the strip.
  • these bores are to accomodate a plate to be joined or coupled together with a plate subsequently made of the strip length in question. It may concern a cross plate or a locking plate to be coupled together with the plate in question.
  • the fact that the bores are in this case disposed centrally of the strip is due to the fact that the strip will subsequently have a V-formed cross section profile of a kind having the V-webs of equal size. Hence follows, that the bores 15 will be disposed exactly in the border zone between the webs. Stamping out the bores 15 is accomplished at the fourth stamp 4, FIGS. 1 and 2.
  • FIG. 7 E shows that triangular cuts 16 are stamped into the strip to permit bending for example at right angles of a subsequently V-formed plate.
  • the cuts 16 are disposed at the same side of the centre of the strip as the securing tabs 13 and the cuts extend from the edge of the strip to the centre of the strip. In such manner the cuts interrupt one V-web whereby the other web will be easy to bend. It is also to observe that the cuts are stamped out exactly at the portions 14 not exhibiting any securing tabs. The stamping out of the cuts I6 is accomplished at the fifth stamp 5 according to FIGS. 1 and 2.
  • FIG. 7 F shows the strips being formed with stiffening grooves 17 along one edge, in fact the edge disposed oppositely to the securing tabs. Forming the stiffening grooves is carried out at the printing station 8 previously mentioned. 7
  • FIG. 7 G illustrates how the strips are imparted with an V-formed or right angled cross section profile, two webs 18 and I9 oriented at an angle to each other being formed. This is made at the profile former 9.
  • FIG. 7 H shows that bulges 2.0 are formed on the webs 18 in connection to the elongated bores 15. These bulges are to accommodate other plates related above and which are subsequently to be coupled together with the plate made of the present strip.
  • the bulges have accordingly a height with respect to the remaining web that is at least equal to the thickness of the other plate.
  • the forming of the bulges 20 is carried out at the forming tool which is located following the profile former 9.
  • the strip thus formed is sheared by means of the shearing means 11 into predetermined lengths while forming bendable plates ready to be, after bending, applied to a desired container portion by pressing the securing tabs into the walls of the containers.
  • the strips are fed substantially continuously from the supply and each of the tools are during a stamping or working operation caused to move with the strip at substantially the same speed as that of the strip, and the tools are returned to their initial position after having accomplished their working operation.
  • FIGS. 1 and 2 also show that the supply 6 consists of a winder 21 accommodating two rolls of strip 12 a and 12h. Strips may thus be wound off the rolls which when they are run out are exchanged for new rolls by demounting and mounting respectively of the side pieces 22 of the winder. From the winder the strips run into the series of stamps by a deflecting roll 23 disposed on an arm 24. On this arm preferably a photo-cell device 25 may be provided warning when the strip rolls run out and interrupting by a main switch not shown, all working functions of the stamps, the profile former etc to make a joining of strips from new band rolls in the winder possible. The time interval between such joining depends of course upon the strip length of the rolls and if then the strip lengths are taken sufficiently great, e.g., several hundreds of meters, the time interval will be conveniently long.
  • the stamp includes a housing 26 which exhibits at its bottom side two tubular supports 27 movable along a pair of guides 29 mounted on a frame 28.
  • the guides 29 are directed parallel to the longitudinal direction of the strip 12, whence follows that the housing 26 is movable in the longitudinal direction of the strips.
  • the displacement of the housing 26 according to the invention is provided by an, e.g., pneumatically driven piston rod 30 in a cylinder 31 firmly connected to the frame 28.
  • the piston rod 30 is at its outer end projecting from the cylinder connected to the housing 26 by an arm 32 depending from the lower side of the housing.
  • the pawl 33 is preferably movable into and out of its locking position by means of a piston or cylinder device 35 actuable in a pneumatic, hydraulic or electrical manner.
  • a protective limit switch 36 serves to interrupt the functions of all stamps and similar if the housing would inadvertently and erroneously move all the way into its leftmost position in FIG. 3.
  • a vertical hydraulic cylinder 37 comprising a vertically reciprocatable piston rod 38. Movement of the piston rod 38 downward is caused by supplying hydraulic medium to the cylinder by a first conduit 39 while movement in the opposite direction is caused by supplying medium through a second conduit 40. Both of the conduits 39 and 40 are flexible to permit the displacement of the housing 26 and consist preferably of rubber hoses.
  • the piston rod 38 is by means of a joint 41 connected to a pressure plate 42, which is slidable along upright column pieces 43 in a support plate 44 attached to the lower, horizontal portion 45 of the housing.
  • a guide element 46 is in turn attached, which, in the case of the stamps 1-3 stamping the securing tabs, has the form of a plate having two edge webs extending over portions of the strips and guiding the strips 12 laterally and further a central web likewise extending over portions of the strips.
  • the plate is attached to uprights which are resiliently displaceable into the support plate 44.
  • a bracket 47 which carries a retainer device or driver generally designated 48.
  • This retainer device includes an abutment body 49 which can chuck the strips 12 between itself and the upper side of the bracket.
  • the body 49 is disposed on the lower side of an arm 51 pivotable about the joint or pivot 50, the outer end of arm 51 being pivotally connected to a piston rod 52 of a hydraulic cylinder 53, which is supported by pivots 54.
  • the pivots and 54 are disposed in stands 55 and 56, respectively, rising from the bracket.
  • the hydraulic cylinder communicates with a hydraulic pump or source by two flexible conduits 57 and 58, one only of which is seen in FIG. 3 (cf. FIG. 2).
  • the retainer device 48 described serves to retain the strips during each stamping operation and thereby to inadvertent displacement of the bands.
  • FIGS. 1 and 2 show hydraulic liquid pumps 61 disposed at each of the stamps l-5 and also a pump 62 disposed at the shearing means 11.
  • the pumps 61 communicate with the conduits 39 and 40 to the cylinder 37 as well as with the conduits 57 and 58 to the cylinder 53.
  • the pump 62 is common to the shearing means 11 and the fonning tool 10.
  • a pressure air source. 63 disposed for the operation of the piston-cylinder device 30-31, and similarly a pressure air source 64 common to the shearing device 11 and the forming tool 10 communicates with the driving means 30-31 of the shearing means and the forming tool respectively. Though the pressure air source 64 is in this manner common to the shearing means and the forming tool, the movements thereof can be controlled independently of each other preferably by electrical means.
  • FIG. 4 shows an enlarged partial perspective view of the stamp 2.
  • the guide elements 46 has the form of a plate 65 exhibitingtwo outer edge portions 66 and 67 extending slightly over the strips and a T-formed central portion 68.

  • the stamp members 70 proper consist of pins rising from the support plate 44 or portions thereof and corresponding to bores or passages, not shown in FIG. 4, in the guide plate 65. These stamp members exhibit an upper surface inclined with respect to the horizontal plane, the uppermost portion of which is pointed or sharp while its lower most portion is more or less gently rounded.
  • press plate 42 On the under-side of the press plate 42 dies 71 are disposed having recesses 72 with the same cross section profile as the stamp members 70. Obviously the press plate 42, when moving downward, depresses the guide plate 65 which in turn, owing to the overhanging portions 66, 67, 68, carries along the strips or bands 12.
  • the stamp members 70 stamping out upwardly directed securing tabs 13 when cutting through the strips and advancing upwardly into the stamped out in an upward direction in the manner described above is extremely advantageous in that the strips thereby may be simply moved along through the other stamps, resting with their plane lower surface on the guide or support elements 46 while the tabs go clear.
  • stamps 1, 2 and 3 for stamping securing tabs.
  • the differences between these stamps are solely that the first stamp 1 has three stamp members 70 foreach strip, the second stamp 2 two members 70 and the third stamp 3 one member 70 for each strip.
  • the fourth and fifth stamps are differently formed.
  • the stamp member of these stamps is attached to the press plate 42 and thereby movable against fixed dies attached to the support plate 44.
  • the fourth stamp 4 exhibits cutting starnp members having an elongated profile corresponding to the form of the bores while the stamp members of the fifth stamp 5 are triangular or angulated to impart the triangular form of the cuts 16.
  • FIG. 5 a partial perspective view is shown of the forming tool 10 and behind the same the shearing means 11.
  • the forming tool 10 includes similar to the retainer device 48 previously described a vertically pivotable arm 73 which carries on its under-side a press body 74 having two downwardly directed, inclined press surfaces 75 and 76.
  • the press body is movable toward and away from a seat 77 exhibiting two angulated channels 78 and 79.
  • Each of the channels are recesses80 and 81 having a. moderate depth and being disposed directly beneath the press body 74.
  • the press body is depressed down onto a V-formed strip 12 disposed in the channel and jams one web of the strip against the surface of the channel and the recess a bulge will be formed in the web.
  • the forming tool 10 is horizontally movable, in that the tool is disposed on guides and movable by means of a piston-cylinder device 30-31.
  • the shearing means 11 includes edges 82 attached to the press plate 42.
  • the edges 82 shear off the strips 12 by a vertical movement against a seat 83.
  • the shearing means is horizontally movable to keep pace with the strips.
  • the profile former 9 in this case consists of in each strip six pairs of rollers 84 disposed on a frame 85.
  • the rollers are driven by a system of chains 86 coupled to a motor 87.
  • the rolls are disposed in such a manner that the upper roller in each pair abuts solely against one web of the strip coming into existence during the rolling, in fact the web or half 18 which is free from securing tabs.
  • the lower rollers on the other hand abut against and carry both of the webs.
  • a successive rolling is accomplished in the conventional manner in that the upper rollers are disposed deeper down in the lower rollers at the end of the station than at the beginning of the station.
  • the pairs of rollers are in this case adapted to pull forth or feed forth the strips from the supply 6.
  • the printing station 8 disposed prior to the rolling station 9 includes two rollers or rolls 88 which are provided with enlargements toprint the stiffening grooves 17 in the strips.
  • the roller 88 may advantageously be driven by means of the same chain system 86 as is used for driving the profile roller 84.
  • the plant described is programmed.
  • the essential units for programming are illustrated in FIG. 6.
  • the plant includes a programmer generally designated 89, which is by electric cables 90 connected to a pulse transmitter 91.
  • This pulse transmitter 91 is in turn through cables not shown in particular in the drawings electrically connected to each of the stamps l-5, the forming tool 10 and the shearing means 11.
  • the programmer 89 includes on one hand an exchangable cylinder 92 which is on its peripheral surface provided with rows of projections 93 and on the other a box 95 disposed on a support 94 and exhibiting a plurality of switches 96 arranged opposite the rows of projections 93.
  • the projections 96 are arranged in patterns forming a predetermined program and they are adapted to actuate on rotation of the cylinder the switches 96 and switch the same to induce a given working moment.
  • Each row of projections and the associated switch serves a tool, e.g., a stamp.
  • the cylinder 92 is detachably disposed on a rotatable shaft 97 supported in a support 98 except the support 94.
  • On the shaft there is an adjustment wheel 99 operative to drive the shaft.
  • the adjustment wheel 99 is displaceable along the shaft by means of a retainer 100 which in turn is movable along guide beams 101 by means of the screw 102.
  • the periphery of the wheel 99 which is preferably rubber coated abuts frictionally against a conical drum 103, which communicates through a gear connection 104 with a sensing wheel 105 adapted to abut against the strip 12 and sense the feeding speed thereof.
  • Said shaft 93 is as well as the guide means 10] adapted in parallel to a generatrix of the conical drum to permit a displacement of the wheel 99 without the same releasing its frictional connection with the drum. It is obvious that the program cylinder 92 is drivable by means of the sensing wheel through the gear connection 104, the drum 103, the wheel 99 and the shaft 97.
  • the rotational speed of the cylinder 92 can at a constant feeding speed of the steps be increased by displacing the wheel 99 in a direction towards the largest end of the drum 103, in the course of which the wheel 99 in consequence of a greater peripheral speed of the drum 103 will rotate at a greater speed.
  • a lower rotational speed of the cylinder is desired the procedure will be reversed.
  • the plant described operates in the following manner.
  • the motor 87 driving the rollers 84 may be electric and is by way of example controlled by means of a potentiometer at a certain constant driving speed.
  • the strips will be fed forth by the rollers 84 from the supply 6 and past the different working tools in the form of stamps, printing rollers, profile rollers, forming tools and shearing means.
  • the feed past the forming tool 10 and the shearing means 11, which are understood to be disposed following the profile rollers, is possible thanks to the relative rigidity of the strips. It is accordingly fully sufficient to feed the strips solely by means of the profile rollers, though of course also other feed members are conceivable.
  • the sensing wheel 105 When the strips 12 move, the sensing wheel 105 will rotate at a definite, constant speed, said wheel in turn driving the program cylinder 92 to make it obtain a speed depending on one hand on the feeding speed of the strip and on the other on the adjustment of the wheel 99 relative to the conical drum 103.
  • the projections 93 actuate on rotation of the cylinder the switches 96 which transmit through the pulse transmitter 91 pulses to the different working means 1, 2, 3, 4, 5,10,11.
  • the stamp member having finished a stamp operation and a securing tab, bore or recess having been formed, the press plate, abutment body and stamp housing will return to their respective initial positions, following which the pawl 33 is made to lock. This process is controlled by the system of limit switches. The working cycle is subsequently repeated in dependence of the program of the program cylinder 92.
  • the strips pass the different working tools they will be formed into plates suitable for boxes or containers of occuring dimensions.
  • the stamps 13 the securing tabs 13 are formed with a uniform spacing. These stamps are so timed in respect of each other that a most even distribution of the tabs will be obtained.
  • the first stamp 1 may stamp twice, while the second and the third stamp 2 and 3, respectively, stamp one time solely during the same time interval. The possibilities of variation are almost unlimited.
  • the elongate bores 15 are stamped out. The spacing between such bores will of course depend on the manner of use of the fitting or plate, i.e., if and how many cross or other fittings or plates are to be interconnected with the plate in question when mounting a container.
  • the work cycle of the stamp and thereby the spacing between the bores is controlled by one of the rows of projections on the program cylinder 92.
  • the recesses 16 designed to permit a bending of the plate are stamped out.
  • the work cycle of the stamp 5 is controlled by a row of projections on the program cylinder, whereby the spacings between the recesses will be predetermined in dependence of the desired edge length of the plate.
  • the length of the fittings or plates may be varied by selecting the adjustment of the adjustment wheel 99 relative to the conical drum 103. If long plates are desired the wheel will be adjusted in the vicinity of the narrow end of the drum, whereby the program cylinder 92 will obtain a comparably low speed of rotation. Hence follows that comparably few work pulses are transmitted to the shearing means 11 and that a relative great length of the strips running at a constant feeding speed will have time to pass the shearing means prior to the effectuation of the shearing. inversely, the wheel 99 is to be adjusted in the vicinity of the larger end of the drum if short plates are desired, the shearing means then coming into action at shorter time intervals.
