MANUFACTURING APER :BOXES .Alhl'lD` THE LIKE.

Application led April 16, 1927. Serial Ho. 184,334, and in Germany August 3, 1926.

This invention has reference to a machine for vthe manufacture of boxes, such as card board boxes and the like eind provided with a neck, in which the neck strip of material t is inserted into the main card board pattern which in this operation places itself with its side portions around the neck strip. ln accordance with this invention the Winding plunger or the like for the production of the neck strip is made in two sections,

. and the wound up neck strip is pushed from` the point ofwinding 'onto an axially displaceable section of the plunger or the like, by means of which it is then forced into a tube or the like together with the main card board pattern body, while at the same time the manufacture of a new neck strip is going on by winding upon the retained'or lagging sectionfof the plunger. By proceeding in this manner the manufacture of the boxes is greatlyl accelerated, and this acceleration of the operation is further as sisted by al movable guiding instrumentality for the neck strip which isfed to thewinding plunger or the like and which by such guiding means is forced against the winding plunger immediately upon the release,

of the same. Controlling means regulating the taking off of the patterns of cardboard from a'supply rovide for a proper and correct timing o the feeding of the cardboard patterns notwithstanding the great distance of the supply from the point of treatment of the boxes,fwhile the feeding of a neck strip is prevented in the case of the failing to feed of a main cardboard pattern by means of a feeler or the like.

'Upon the' accompan ing drawing the invention is illustrated by way of exemplification in Fig. 1 in side view with partial l longitudinal section; and'in Fig. 2 in front u view of the machine. Fig. 3 is a plan view t of'part of the machine. In Figs. 4 to G, the machine is shown in the same iongitudi- ,M nal section, as represented in Fig. 1, but with a. diiferent Irelative operating position of the working parts. Fig. 7 Y illustrates a neck strip and a main card board body before assembling ltheysame, and Fig. 8 shows o the finished box.

A. strip of card boardor similarmat-erial l is drawn oif `from a supply roller, not shown, by means of a tappet, pusher arm or tbe like 2,` 3 and by means of a rocking 55 lever 4 operatively connected thereto, and it is then passed to a gluing device 458 by which it is provided on its underside with a strip-like coating of adhesive material. The operation of the lever 4 is effected'by a bar 59 which is drawnl against a cam disc 62 on the driven shaft 63 by means of a spring acting onvroller 61.y The neck strip 1 which. is provided with lue or the like is fed by means of guide ars 5 disposed laterally of the glued strip to a cutting device 6 and to a rockingly disposed guide channel 7 by means ofwhich the neck strip is moved to the winding mandrel,I plunger or the like 8. The guide .channel 7 is rockingly reciprocated in the direction of the winding mandrel 8 by mans of a pinion 9 and rack bar 10 operatively connected to a cam disc l1 on the driven shaft 63. The rack bar 10 is connected to the under-knife df the cutting device 6 and is adapted to vertically reci recate same, while the upper knife is stationary. At its extremity a hollow shaft 47 carries the lwinding mandrel 8 which is exchangeably .connected thereto, the said shaft 47 be'ng rotatably journalled in a support 12` and being adapted to be rotated intermittently v at certain timed periods by means of a gear wheel 48 which is temporarily engaged by apartially toothed wheel 5G mounted on the 8d drlving shaft 49.

Adjustable supporting v "springs 13 mounted on a frame 14 are longitudinally displaceable over the winding mandrel 8 and a plunger head 15. The frame 14 is preferably suspended from a bar 51 adapted tov be reciprocated and to be. guided in the frame 12, 12B. The movement ofthe bar 51 with the frame 14 and' the supporting springs 13 is effected from a camf disc 52 disposed vupon the shaft 49 95 and with the groove 53 of which the roller' 56 of a lever 55 is adapted to engage which is 'rockingly disposed on the stud 54. .The slotted end of the lever 55 is engaged by a tappet 57 on the bar 51. The supporting 100 springs 13 upon their displacement slide with rtheir lugs 16 (Fig. 3) in the grooves 17 of the Winding mandrel 8. The grooves 17 extend also along the part 46 and on this member there are provided running or contacting surfaces Which are adapted t0 be employed for different sizes of plungers. The plunger head l5 is exchangeably secured to an axially movable rod 18 which is disposed in the interior of the hollow 1m shaft 17 of the winding mandrel and projects therefrom. The axial displacement of the bar or rod 18 is effected by a lever 65 roekingly disposed on the stud 64 and being engaged by means of a roller 66 with a groove 67 of the cam disc'52. A clampin evice 19 disped on the winding mandre between the lower pair of springs 13 serves for the purpose of retaining the wound up neck str1 eomgiresslon spring 20 is provided adapted to orce the pressure jaw 21`againstvthe windin head 8, while the said jaw is subsequently lifted off by a cam 44 operated by a cam disc 68 on the shaft 49. A tube or the like 22 adapted to snugly surround the finished boxes carries at 1ts end confronting the plunger springacting side walls which are inwardly projected. A bracket or supporting arm 24 is projected with its supporting surface 25 between' the uide bars 26 of a iding frame 27 in ont of said tube 22 1n such a manner that the supporting surface 25 is adapted to catch and become engaged with a main card board `attern 45 delivered from a supply 29 in tle usual manner by means of a s 1de, not shown, and a pair of feeding rollers 28. The supporting arm 24 'serves merely for the quicker and more reliable feeding of the card board pattern in front of the opening of the tube or the like 22, and the said arm is controlled from the cam disc 68 b means of a bar 69. A feeler 30 whichV is preferably loaded and is engaged between the rollers 28 is rotatably disposed with its shaft 31 in front ofthe container for the supply of card board Apatterns in such a manner that, upon the lowering of a piece of card board 45, the feeler by means of aA stem of levers 42, 43 acts upon a bar 32. with its yfree end this bar isengaged in a wedge-like fashion between the ide 33 of the tappet carriage 3 Aand a gui e 34 which 'is moved transversel with relation to the guide 33 by means o springs 35. `A tongue vor tappet 36 having'smtable guiding means is moved in the, guide 34 and coo rates with an angular stop 37 secured to t e tap` pet`2 in such a manner that it does not become engaged with the angular sto upon the operation of the feeler 30, so t at the tap t 2 will be operated and the strip of ca ever, the V feler 30 is not actuated, that is to say, in case no card board pattern is lowered, the tongue or tappet 36 moves below` the angular stop 37 and prevents the tappet 2 being forced against the paper strip 1, so-that the said strip is not caught between the tappet 2 and the tappet carriage 3 and is prevented from being moved ,forward into the guide channel 7. A pressure roller 38 .is moved in spaced periods of time spring-actingly against the windat the connecting joint and a board may be fed forward. If, howing mandrel 8 in the well known manner by means of a camdisc 39, a system of levers 40, and pawl-and-ratchet means 41.

In view of the exchangeability of the winding mandrel and of the plunger, or of the head portions thereof, and by the adjustability of the other operating elements,

it becomes possible to manufacture in this manner boxes of different sizes and shape.

The in substantially `as follows: The previously folded and gummed or glued neck strip 1 is advanced by means of the tappets or pushing arms 2, 3 and tlirou h the cutting device 6 and the rockable gui e channel 7 said channel being 1owered,in order to make room for other simultaneously operating parts of the machine, as appears from the following description. Upon the release of the windin mandrel 8, that is to say, upon the remova of all interfering operatin parts from-the path thereof, the guidin `alla neck strip 1 is oscillat in the direction of the winding mandrel 8 and the end of the strip 1 is clamped by means of the clamping element 19 in such a manner that-it becomes disposed substantially upon the middle portion of the lower 'longitudinal' art 'of the winding mandrel (Fig. 2). T e winding mandrel being newl rotated direction of the arrow is Fig. 2), it carries t e strip 1 along ode of operation of the machine is nnel 7 with the with it which is simultaneously retained in position by the ressure roller 38. After the completion of t e rotation of the mandrel, the frame 14 with the supporting springs 13 is pushed over the strip 1 which latter is now moved onto the plunger section 15 (Fig.

4) by means ofthe lugs 16 of the supporting springs 13 sliding in the rooves 17. At the same time the main car board pattern 45 which has been retained by thecarrying bracket 24 is now released and is dropped in front of the tube member 2'2. Thereupon the parts15 and `13 are commonly moved in the direction of the tube member 22 and the plunger 15 pushes the card board attern 45 into the spring-acting part 23 o the tube 22 -and in this movement it causes the folded edge portions of the card board pattern to be bent in contact with the neck strip 1 which has been advanced by the supporting sprin s 13, the-folded marginal portions be ing t ereby secured-to the glued parts of the neck strip (Fig. 5). The frame 14. with the supcporting springs '13 is then rapidly return to its initial position, while the plunger section 15 pushes the box thus obtained into the tube 22 so farthat-` the box becomes disposed behind the projecting, spring-acting tube section 23, sothat upon the then occurring return movement of the plunger section 15 the box is retained by the projecting walls 23 and remains in the tube 22. Upon the commencement of this stage of operation a fresh card board pattern 45 is also admitted to the supporting arm 24 and consequently the feeler is also operated upon the passage of the particular card board pattern and thereby the tappets 2, 3 are released and by this means the next stri l is pushed forward, asalready describe throughV the cutting element 6 and the lowered guide channel 7. After these supporting springs 13, upon their return, have moved past the winding mandrel, the guide channel 7 with the strip is rocked in the direction towards the winding mandrel, as above described, and the strip is thereby caught and is carried along by the now rotated 'winding mandrel, and so on, as hereinbefore described. Thus, several stages of movement are carried out `during the same periods of time, so that no part of the operatin time is lost.

he finished boxes are given sufiicient time to dry upon beine pushed through the tube 22 which surrounds them snugly fitting It should, of course, be understood that the invention is susceptible of modifications and changes in the different arrangement of the parts and the construction thereof, without deviating from they scope and spirit of the invention as expressed in the appended claims.
