  "Improvements to machines used in the manufacture of cardboard and other containers"

 <Desc / Clms Page number 2>

 
This invention relates to machines used in the manufacture of cardboard and other containers, these machines possibly being automatic or semi-automatic, and its object is the creation of machines intended to effectively produce containers starting from paper, cardboard. or other similar materials in the form of sheets or strips.



   In general, the machines according to the invention used for the manufacture of containers starting from a raw material in the form of sheets or strips, comprise on one side combined devices operating automatically to form a tubular element and the other of the automatic devices allowing insertion and fixing in the tubular element of the base or bottom of the pot, the said bottom also being made up of the same raw material in the form of sheets or strips .



   It is preferable that the machine comprises devices by means of which the tubular member can be automatically moved from its manufacturing position to the place where it is to be provided with its bottom, so that the manufacture can be moved. 'perform in a fully automatic fashion. Paper, cardboard or other suitable materials in the form of sheets or bands feed the machine which debits the finished articles into containers. The machine can bring the containers on a suitable conveyor, hence. they can, if desired, pass to an apparatus in which they will be waxed and then passed to drying.



   According to a preferred form of the invention, the machine consists of a mobile and rotary table to which are fixed at determined intervals various mechanisms operating automatically, while devices are provided for actuating said table in the table. purpose of moving partial containers. manufactured, step by step, according to positions that allow

   The purpose of mechanism A is to automatically form a tubular element by means of a cut sheet of paper, while mechanism B also aims to make a second tubular element of the same material. Each element

 tubular debita by mechanism B is inserted inside each tubular element debita by mechanism A so as to. constitute a tubular element composed of two parts which constitute the body of the. container.



   Appropriate rimmed bottoms or base discs are made automatically by the mechanism 0 by means of a strip of paper placed on the roll c to be inserted at one end of each of the tubular elements composed.



  This mechanism also includes devices for effecting automatic partial fixation of the bottom in the tubular element.



   Mechanism D is used to automatically carry out the complete fixing of said bottoms in the composite tubular elements.



   Finally, the mechanism E is intended to automatically produce a second bottom or base disc bordered by means of the strip of paper placed on the roll 9 and to effect the insertion of the fixing in the tubular insulation thereof. .



   Suitable unwind spools for receiving the waste of the paper web leaving mechanisms C and E can be provided if desired, but these are not shown in the drawings.

   It is therefore sufficient to mention that the rotation of a shaft 11 driven by means of a chain 13 connected to the shaft 9 serves to fold around a tubular mandrel 14, a sheet of paper coming from a stack 1a, the edges of the folded sheet overlapping one on the other. These overlapping edges come into contact with a punch with multiple notches cooperating with a mandrel so as to force on the thickness of a sheet a series of tabs regularly spaced from each other, which are pressed through them. correspondingly spaced openings. laying, formed in the thickness of the other sheet.

   By means of the device described later, the two sheets are subsequently given a relative movement such that said tabs engage with said openings thus causing sufficient bonding of the edges of the folded sheet in order to form the folded sheet. desired tubular element,

This finger is arranged in such a way as to cause a back and forth movement to the shaft. lever one of the ends of which is coupled to one of the arms of lever 20, the other arm of this lever being assembled by link 19 to arm 18.



   The other end of the lever arm 21 is connected to the mechanism generally indicated at F in FIG. 1. This mechanism F is intended to withdraw the tubular element 22 from the mandrel 14 and to transfer it inside the receiving device 8. adjacent to mechanism A. It is also intended to ensure the displacement

  The removal mechanism N is shown in detail in Figures 5 to 11 of the accompanying drawings and this mechanism comprises a slide 23 mounted on a bar .2.4 extending outwardly from a support 25 mounted on the center of the party a.
 EMI10.2
 



  The slide 2a carries a fixed arm and a movable arm, the latter being pivoted at 2.8. on the slideway 23. The front ends of these arms 26 and 27 are adjacent to each other and form the jaws of a clamp.

 of the accompanying drawings. The upward movement of the arm 29 a. as a result of ensuring the closure of the two jaws of the drilled clamp by the ends of the arms Sa and 27.



  The desired movement of lever 29 is obtained by a

  It should be noted that the arms 3a and 27. are placed on the same axis as the receiving device a adjacent to the medium.

 canism g, It follows that when the arm z is actuated in a movement to the left of the position shown in

 <Desc / Clms Page number 11>

 Figures 5 and 7, the coil 33 will be brought against the pin (see Figure 10) and from there a subsequent movement of the arm towards the. left will move the slider along bar 24.

   The jaws of the clamp will pass through the orifice of the receiver device ± and will come to be placed in a position such that they will come to grip one of the ends of the two overlapping edges of the tubular element 22 (see figures 4 and 6), placed on mandrel 14 of mechanism A.



   During the first part of the rearward movement of the arm 21 from the position shown in FIG. 6, the lever 33 is moved to the right around its pivot causing the engagement of the pawl on the lever 29 which is thus also released. placed to the right around its pivot point 31. This movement brings about the approach of the jaws which grip the end of the overlapping edges of the tubular element 32 as is clearly shown in FIG. 11.



   The subsequent movement of the lever 21 causes the slide 23 to return to the rear along the rod 24 thereby causing the tubular element of the mandrel 14 to be removed from the mechanism A and the said tubular element to be placed in it. the calibra or orifice of the receiving device 3.



   It should be understood that during said removal of the tubular member 22, the overlapping edges thereof are moved in the desired relative movement.



   When the tubular element 22 is in the required position inside the receiving device 11, the jaws open to release said element. This release is effected by providing the pawl 34 with a dependent arm 34 'which at a certain moment during the return movement of the slide, abuts against a trigger plate 38 and causes the release of the beak of the lever the latter to its turn ensuring the descent of the arm 27, which causes coverage of the jaws.



   The final movement of the slide back to the position

The receiving device 8 mounted on the table 1 is shown in detail (scale 1/2) in figures 1213 and 14 * view of the device comprises a body or hollow frame fixed to the table 1 and in which a. rotary sleeve 40 provided with a corresponding conical perforation along the greater part of its length with the conical tubular element 22.

   This sleeve is intended to receive this tubular element and to serve as a support, The inner part of the conical perforation is

The rotary sleeve 40 is provided at its end with a toothed wheel which meshes with a corresponding rack 43 fixed on the edge of the rotary table L (see also figure 1)

 The purpose of this device will be deorit below.



   The general shape of the conical tubular element 22 after its introduction into the receiving device is illustrated in perspective in FIG. 15 and it will be seen that the superimposed edges connected to each other are in the highest position.

 <Desc / Clms Page number 13>

 The latter are placed in the body 39 where they are subjected to the action of springs the purpose of which is to ensure the locking of the sleeve in the two respective positions and to prevent any accidental displacement outside said positions.



   The mechanism indicated in B (figure 1) is in all its respects similar to that described above and de signed by A. It is intended to produce a tubular element starting from a sheet of paper, but from a diameter slightly larger than that of Isolation 22. This mechanism B is driven from the shaft 40 by a chain 46.



   The tubular element produced by this mechanism B is intended to be removed from the mandrel in order to be inserted inside the tubular element 23 supported by the receiving device a. This operation is carried out by means of the removal mechanism indicated in G (figure 1), mechanism identical to that described above under the reference F.



   The two tubing elements, having been placed one inside the other, constitute the tubular element composed of two parts as shown in perspective, in figure 16. It is to be observed due to the superimposed edges of one of the elements. tubulars are placed diametrically opposed to those of the other part. This compound tubular element is designated by the reference numeral 47
In some cases, the row of tabs of each of the tubular members extend at the location of the member through appropriate openings.

   But in other cases, the tabs of the inner tubing element may be arranged so as to protrude outwardly through the appropriate openings of that particular element, in which case the interior of the tubular element. composed of two parts may be internally devoid of tabs.



   After the manufacture of this composite tubular element, the table 1 receives two new intermittent rotary pulses by means of the cam 5 in order to bring the said element supported by the device $ in front of the mechanism indicated by C (figure 1 ).

 <Desc / Clms Page number 14>

 



   It should be noted that during this manufacturing stage and during the time when. the table 1 is stopped, that is to say between the two intermittent rotation pulses, the outer end of the compound tubular element 47 can be closed, widened or opened so as to facilitate the introduction of a base or disk borders. For example, a conical mandrel could be made to penetrate into the outer end of the composite element. This mechanism is not shown in the drawings.



   Mechanism C is shown in detail in Figures 17 and 18 (1/6 scale) of the accompanying drawings. It comprises two main devices, namely, a device for making a rimmed disc by means of a strip of paper coming from the roll c (figure 1) and secondly a device serving to introduce these discs into the end of the tubular elements. compounds. Part of the first of this device is also shown in Figures 19, 20 and 21 (1/3 scale) which show different stages of the operation.



   This mechanism comprises a main shaft 49 driven via the axis 10 by means of the chain 50, On the shaft 49 is mounted the eccentric 51. actuating the plate 52 to which is connected the coupling rod 53 serving. transmitting the movement to the guide rail in the frame 55.



   The slide 54 supports at its inner end a hollow punch 56 (figure 20) which is arranged so as to cooperate with the cutting edges 57 of a fixed circular die for the purpose of cutting a circular disc in a strip of paper c1 which is fed from roll c intermittently via pressure rollers 52 placed between the punch and the circular die. These pressure rollers 59 are arranged so as to come into operation at the appropriate time by means of a device of articulated levers 60 actuated during the movement of the slide 54.



   After cutting the circular disc in the strip of

 <Desc / Clms Page number 15>

 paper c1, the punch 56 continues to move inward, this movement being opposed by the Inaction of a pressure ring which is subjected to the influence of a pressure spring.

 compression e. The purpose of this subsequent movement of the piece toe is to fold the edges of the circular disc so as to form a border as will be easily understood by looking at figure 30, the disc reported in this way is represented by 63 .

  This latter device and its operation are shown
 EMI15.4
 shown in detail in Figures', z3 and 24. It consists of a body or main frame mounted on the lower part of the frame 55 and provided with a cylindrical perforation 68 in which is arranged a sliding sleeve 69.A the interior of this sleeve is a movable axial rod 70, the inner end of which is coupled at 71 to the lower end of a lever 72 pivoting at 23 on the frame. The upper arm of this lever .'la
 EMI15.5
 is connected by a coupling rod 21 to the preoedoument fiùnented slide. Through this device, the movable wing rod .70. is impelled during the movements of the slide.



   A pressure spring .25 serves to couple the rod 70 and the sleeve 69, and during the movement of said rod (to the right) from the position shown in figure 22 to that
 EMI15.6
 shown in figure 23, the sleeve is moved in a similar fashion by the action of this spring until this movement is stopped by the outer part of a stop ring 1'J coming in con¯

 <Desc / Clms Page number 16>

 tact with the body or frame 67.During the movement of the sleeve 69, the outer end of an expandable mandrel 77 engages the rimmed disc 63 (which has been brought from the punch 56) and directs this disc inside the compound tubular member 47 supported by the device $ (Figure 23).



   A similar subsequent movement of the rod 70 has the effect of causing the outer end of this rod which is conical at 78 to cause the diametrical extension of the mandrel 7, the side parts of which consequently come into intimate contact with the rim. inner circular disc 63 which thus comes into contact with the inner wall of the tubular element wire.



  This action will be easily understood by means of Figure 34 which shows the mandrel 77 in its fully extended position.



   The same movement of the rod 70 causes a relative movement between the collar 79 and the daughter sleeve This collar 79 is rigidly connected to the rod 70 by means of the rod 80 and serves to ensure the operation of a kind of iris mounted on the outer end of the sleeve 69.

   This iris is composed of a series (the segments 81 rotated and placed around the sleeve 69, each of these segments having two inclined surfaces .sa and .sa respectively, Normally, and as shown in figures 22 and 23, an extension the interior of the collar 79 bears against the surface sa and maintains two elements in their open position while after a certain relative movement of the collar 79 and the sleeve 69, said interior extension moves on the surface. and causes each element of the iris to close, resulting in the outer ends of the tubular element being folded back into the end portion of said element, which will be easily understood by referring to Figure 24.



   Following these operations) the rod 70 is brought back (to the left) and the organs return to their normal position as shown in figure 22. During this return movement, the elements 81 of the iris are in their position.

 <Desc / Clms Page number 17>

 opening and the outer end of the mandrel returned to its rear position after completion of the tubular member composed of 47.



   It should be noted that during the lapse of time during which the rimmed disc 63 is inserted a plate 84 carried by the slideway serves to hold the outer end of the tubular element compound 47 against any external axial thrust.



   According to the manner described above, the base element or bottom of the container is made automatically, then iridescent in the compound tubular element or it is fixed prior to these subsequent operations,
Table 1 is now brought to the desired level to bring device 8 supporting the partially finished container to a position corresponding to mechanism D of Figure 1.



  This mechanism D is shown in detail in Figures 25, 26 and 27 (1/10 scale); Fig. 25 also shows part of the rotary table 1 as well as different elements combined with each other.



   In this case, the shaft 10 drives a single cam 86 with which a roller 87 will cut on a rod 88. The upper end of this rod 88 is connected to the arm of a double lever 89 pivoted to the frame 90, while that the other arm of said lever is coupled by means of the rod 91 to the upper arm of a second lever 92, also fixed to the frame 90.



   Said frame also carries a support serving as a slide for a device intended to complete the fixing of the flanged disc to the end of the compound tubular element. This device and its mode of operation are shown more fully in Figures 28 to 31 (1/3 scale) of the accompanying drawings. Inside this support 93 is arranged a movable sleeve. 'inside which is an inner shoulder 95.



  Inside the sleeve 94 is a rod, the part 97 of which is of larger diameter, this latter being provided at its end.

 <Desc / Clms Page number 18>

   external moth of a. piston 98. The other end of this rod 96 is coupled to the lower arm of the lever 92 of which it was mentioned previously, so that the initial movement of the cam 86 is transmitted by the members 87,88,89,91 and from said lever 92 to the rod 96 which is mounted so as to. receive a back and forth movement.



   During the first part of the forward movement of this rod 96 (towards the right), it drives towards the right by means of the compression springs 100, the sleeve 94 until such time as. this movement is stopped by the stop ring 101 abutting against the support 93. The various elements of the device now occupy the relative positions shown in FIG. 29.



   The sleeve 94 carries at its outer end an iris composed of a series of pivoting segments 102 arranged around the sleeve and held in place by means of elastic rings 103.



  The inner wall of each of these segments is formed of two separate inclined surfaces 104 and respectively with which the piston 98 referred to above and the rod cooperate.



   The normal position of the elements of the iris 102 and of the piston 98 is shown in Figures 28 and 49. When the rod starts to move, the piston 98 is brought into an intermediate position between the two surfaces. relatively inclined 104 and 1Q5 of each of the iris elements, whereupon the outermost elastic ring 103 serves to close the iris elements, thereby having the effect of further folding the end of the compound tubular element placed in the device B. This operation will be understood by referring to Figure 30 of the accompanying drawings.



   Continuing its movement, the rod 96 will bring the piston 98 into contact with the surfaces 105 of the elements 102 of the iris and cause, the opening of the iris, the piston 98 continuing its movement with the aim of folding back the iris. end of th-

 <Desc / Clms Page number 19>

 tubular member on the circular inner / surface of the disc rim This final operation will be readily understood by referring to figure 31.



   The return movement of rod 96 naturally causes piston 98 to withdraw from inside the end of the partially completed container and returns the various members to their normal position as shown in Figure 28.



   It should be noted that the tubular element provided with its bottom can, if desired, be removed from the machine at this stage of the operation and passed if from the sire to an appropriate waxing apparatus, so as to obtain a container. completely finished, however, it is preferable to insert into the container thus formed a double bottom as will be described below.



   This mechanism D also includes devices for ensuring the alignment of each of the receiving devices with the various cooperating parts of the mechanism arranged radially when the latter return to their rest position. For this purpose, each of the receiving devices a is provided with an element in which is cut a V-shaped notch lQµ into which engages, when they are at rest during the intermittent periods of rotation, a finger 107 (see figures 25 and 27). This finger 107 is connected by means of a key and groove assembly to a slide 108 which in turn is coupled by a hinge to the lower arm of the lever 92 mentioned above.

   The object of this device is that, while the said lever 92 is oscillating, the slide 108 is actuated so as to make the finger 107 penetrate (or withdraw) the V-shaped notch 106 at the appropriate desired moment. , this fixing the position of the devices 8 in line and in position with respect to the various cooperating parts of the series of the mechanism.



   In the mechanism is also incorporated a stop plate 109 recounted on a slide placed on the frame 90 so as to come to be placed behind the tubular element 47 hanging.

 <Desc / Clms Page number 20>

 during the time that the piston 98 operates at the inner end of said element.

   The plate 109 is arranged to move against the tubular insulation 47 by means of the bracket 110 mounted on the rod 91 and positioned so as to come into contact with a cleat 111 subjected to the action of. a spring and mounted on the plate 109
Following the operations described above, the -table 1. is imparted the desired movement intended to bring the particular receiving device 8 supporting the element. tubular partially finished in a position adjacent to mechanism E (figure 1). This mechanism E is intended to produce a second rimd disc by means of the paper roll e, to insert one of these discs into the bottom of the partially finished container or tubular member and to effect the fixing thereof in the bottom. the said background.

   The mechanism which is illustrated in detail in Figures 32, 33 and 34 (1/6 scale) of the accompanying drawings, is driven by the shaft 2 by means of a chain 113.



  This mechanism is on the whole similar to that more particularly described above and designated by the reference 0.



  In fact, the devices and the way of producing rimmed discs are identical to those shown in Figures 19, 20 and 21 except that the dimensions of certain parts are codified so as to obtain a disc or bottom of any size. little smaller. Therefore, it is not necessary to give a more extensive description concerning the manufacture of this second disc bordered by the mechanism to which it is currently referred.

   It should however be mentioned that these discs are brought after manufacture by means of a conduit serving as their guide indicated at 114 (FIG. 32), in a position corresponding to the inner end of a. 'partially finished container placed in the particular receiving device $ ,,
However, in order to make it easier to recognize the different parts of this particular mechanism, they are represented by reference numbers ten times.

 <Desc / Clms Page number 21>

 the. value of those corresponding to the reference numbers given to fibers 17, 18, 19, 20, 21, 22, 23 and 24.



   In addition, the devices incorporated in this mechanism and intended for fixing the second disc bordered in the. base or end of the partially completed container, are also similar to the device previously described with respect to Figures 22, 23 and 24, except, in this case, the iris is omitted. Here too, it is not considered necessary to include a further description of the method of operation of this particular device, which is shown in detail in Figures 35,36 and 37;

     it is however necessary to mention that during the movement of the rod 700 to the right, the second rimmed disc 115 is placed on the bottom of the partially finished container, as seen clearly in Figure 36, while by the subsequent movement of with the shank 70O to the right, the expandable mandrel 770 is moved apart so as to press the rim of the disc 115 and bring it into intimate contact with the folded end of the tubular element which is referred to above. After this operation, the rod 700 is returned to its normal position, this having the effect of withdrawing the mandrel from the base of the container.



   While the mandrel 770 is performing its action on the base of the partially completed container, a US retaining piston supported by a slide 117 is arranged so as to penetrate through the opening of the open outer end. of the partially finished container, so as to abut against the inner face of the first fixed disc and forming the bottom.



  The desired movement of the slide 117 is obtained by means of a lever 118 cooperating with a cam 119 driven by the shaft 9.



     The container is now finished as to its manufacture, but of course, if desired and generally preferable, it may be treated with paraffin or other material, using any suitable apparatus.

 <Desc / Clms Page number 22>

 



   Although it is easily possible to manually remove the terainated containers from their mandrels or receiving devices 8, it will be possible. however make use of automatic devices to perform this operation. Thus the machine which: has just been described comprises devices shown in FIGS. 1, 17, 18 and 38 comprising a piston 120 to which a reciprocating movement is imparted by means of the connecting rod 131 articulated to the lever, the latter itself being actuated by the reciprocating movement of a rod 74 forming part of mechanism C.

   During operation, the piston 120 presses against the bottom of the container which is located in the chuck or receiving device a and causes the ejection of said container. The containers thus ejected may, if desired, be transferred to a conveyor belt or other means of transport which may be arranged to bring the containers to the appropriate waxing apparatus.



   When the container has been removed from its mandrel $, the latter passes again to mechanism A (figure 1) and the production of a new container begins again.



   In this way, in the machine particularly described above, twelve containers are produced at each revolution of the table; it is naturally understood that this latter and the various mechanisms described are connected and assembled in such a way and that the time period relating to each of the different operations is calculated so that the whole machine functions in a manner keep on going.



   Either one or the two expandable mandrels 77 and 770 which have been described above can with certain advantages be replaced by two-part expandable mandrels as shown in Figures 39 to 43.



   In this particular arrangement, the ex tensible mandrel consists of two sleeves, one inside 123 and the other outside 124, each of these sleeves having four

 <Desc / Clms Page number 23>

 longitudinal grooves 125 and 136 respectively causing
 EMI23.1
 thus the for4i & tion of four segments for each 1D.anchùn ..



  The inner end of the sleeve L9 ± is fixed on a slide T7 which corresponds <; I, 11X Jlétfents.G.2 and 9p described previously and which is used by means of a 6c1 'or .3 to put the sleeves in position 123.
 EMI23.2
 



  A movable rod 9 axLleuent is provided which corresponds to the previous rods of Gorites 2S 9't 700. This rod has a conical end l.aQ. which, when it moves upward, cooperates with the conical ùterex surfaces l3l. of the end of the iaa.achOl1 J3., thus causing the dela-.oatnent ra- dial or, tr7. oaths of the said Manchon. The movement of the segments of the Sleeve 1¯ causes the corresponding displacement of the seeds of the outer sleeve 14. this resulting in bypassing the operating end. of the mandrel in the extension position such as nolHrJe in figure 41.



  During the rewinding due to the tio 19, the segments of the two sleeves are brought back to their normal position due to the natural glasticity of the-lt 1 of which these segments are constituted.



   The principle advantage of this particular form of the extensible chuck lies in the fact that when it is in
 EMI23.3
 her. extension position, (Figure 4ri) the circumferential surface of the 9? rtie operation is continuous, that is to. say that the intervals, the coming from the slots. l26.

   are filled by the parts of the segments of the inner sleeve, so that in the operation, the mandrel will cause the extension over the entire surface of the rim of the disc forming the bottom without causing any damage,
In Figures 44 and 45 is shown a modified form of the invention in which, as an alternative to the arrangement-
