PAPER-Box MACHINE` -AND *.rHnLIKE;

Appuomn mea nay is, 1927, serial No.`1e1,6es, and in Germany may 12, 192e.

This invention refers broadly to improvements in the manufactureof aper or cardboardboxes and the like and) in particular to that part of the artlin which the cover or lid of the box is mounted automatically and an rapid succession upon the body or ybase part of the box, and it is intended to generally improve the processvof manufacture and the ing belts or aprons movable in parallel re-v lation to each other andv alternatingly or staggeringly arranged, means being provided in connection with the device accordin to the invention to cause .the most advance lid or base section. to be placed by slides or the like insuperposed relation and to be then assembled to each other, whereupon the'thus connected box sections may be `fed, if desired,-into a device or part of machinery by vmeans of which they may for instance be 3o provided with a wrapper ofv paper or the like.

The supporting yand guiding means for the box sections at. the point uof closure or assemblage are arranged in such amanner that the box sections before the mounting of the cover or lid'bmay be automatically trued or smoothened with accuracy, means being provided to adjust and to compensate any inaccuracies of the edges ofthe box sections so that in everyIcase the' lid or cover` may be mounted upon the base section ,of the box 1n the regular run of the machine and wlthout any interfering disturbance.l

.l The invention will be more particularly described by reference-to the accompanying drawings'showing by vway of example some f forms of preferred embodiment of the principles of the invention mFi .1 in vertical 1ongitudinal section, and in ig. 2 in vertical transverse section, an'd in'Fig. 3 in planlview. so Figures 4-6 illustrate the mode of operation of the'device forl the assembling of the box sections; and Fi 7 is aperspective of the entire box. In Figures-840 a modification is shown which 'is particularly adapted for the smoothening and truing of the walls of the box, Fig. 8 showing the parts in front elevation and Fig. 9 in plan view, and Fig. 10 the mode of operation of this part of the device as applied to the truing of' the walls.

machine by means of the aprons or conveyor belts 1, 2 which are 'alternatingly arranged,

and upon which the base sections 3 and the covers Nor lids 4 are respectively mounted closely adjacent to each other. The m untlin(lr of the box sections may be eiected m lnualy or by machinery` in which case the as# sembling device may be directly united to the box making machine. disposed at di'erent levels' and in such a .manner that the base sections 3 of the boxes are moved at the level ofthe machinevtable Aagainst a stop 5 while the covers 4 are fed onto a plate 6 in a guideframe 7. The apron The aprons 1, 2 are or belt 2 and the plate 6 are spacedly disposed above the machine table 24 which corresponds,

to a. multiple of the heights of the boxes. A-

to the belts or aprons moves those

boX sections

3, 4 which have been the furthest advanced towards the point of assemblage, causing the base section 3 of{the .box to come in contactV with a movable stop 10 which is controlled by a cam disc or the ike, while the cover is moved 'against the stationary stops 11. In the forward movement of the covers kor lids 4 they slide from the plate 6 onto the stationary supporting bars 12 and then upon slide 8, 9 which is reciprocate'd transverselyt the spring actuated (yielding) stops 13. n

Underneath the base part `3 which rests against the stops 10' a hollow bar or tube 14 is vertically reciprocated in the frame 15 and its head plate 16 carries the levers 17 pivotally`-secured 4thereto and spring actingly forced against the 'plate 18. This plate 18 is movably connected to the rod 1.9 which is movable in the tubular bar 14. The parts 14, 19 are controlled in-any. suitable manner, thus `for instance by means of cam discs and by the

levers

20, 21 cooperating therewith'. On the levers 17 thin plate spring lingers 22 are connected which uponl the .raisingmofthe tubular bar 14are adapted to pass through slots 23 ofthe machine table 24. Above the cover or lid 4 resting against the stop '11 a plun erA or piston 25 is reciprocatingly guided whic is moved in a manner not shown in the they are made to rest against the stops 10, 11.

rlhen the spring acting ngers 22 are raised .and are moved past and about the base sec-A tion 3, and are then allowed to move inwards which movement is produced by iirst raising the plate 18 together with the tubular bar 14: and then moving the plate 18 with relation to the levers l? in the highest position the ends of the spring fingers 22 have passed through the apertures of the table and have entered into, the covers or lids 4: (Fig. 4). Now, the cover is lowered, while the spring fingers 22 and the plunger v25 are descending together and retain the cover between them which slides along the springY actingly yielding supporting bars '3.3. As soon as the cover ap roaches the base section of the box the en s of .the spring ngers 22 are moved outwards causing the cover to be trued and smoothened and to be adjusted with relation to the base section. 'Ilhis will cause the edges of the cover. in some cases' to be bent somewhat outwards, while the edges of the body of the box are forced somewhat inwards so that 'the cover will be engaged with the bodyl or base part oi the box free Jfrom obstructions (Figo) .whereupon the spring fingers 22 are lreturned to their initial position (Fig. 6).

i This terminates one cycle of operations; the

slides 3, Qeed the next succeeding box sections into the machine, while the assembled finishen box is discharged from the machine past the reviously withdrawn stop 10 and by means o a chute or .conveyor or the like 27 and may be introduced into a labelling machine or wrapping machine or the like.

The guiding members for the box sections and other parts of the machine may be made adjustable, in order to be able to operate on pieces of .work of different sizes. With a corresponding arrangement of the s ring fingers`22 the invention is also ap lica le to oval sha edland round boxes in e manner l describe the operation being accompanied byan automatictraning and adjustment of 1 ceuracies ofthe box sections. On account of the accurac of operation of the -machine -it ma be wor` ed at very highspeed.

n ir

igures 8-13 special means are shown vfor the truing of the edges and the walls of the box sections, and by means thereof the walls oredges ofthe box sections before or after assembling them into a finished bOx are treated with the pressing means adapted to force the resilient material inwards to such I an extent that any of the edges or walls which :modena by slight inaccuracies or deiciencies of. loperation have become bulged outwards are relieved from the irregularities of tension and by their elasticity after the release of the pressing means will assume the regular vertical and straight position with'relation to each other instead of the unsightly bulged out appearance which interferes Agreatly with the normal and regular assembling of the difterent box sections.

Pressing dies, plungers or the like- 28 and respectively 29 may be employed for the purpose mentionedl which are arranged at the point of assemblage of the box sections and which, lafter the box sections have been fed to the point of assemblage will exert an in wardly directed pressure against the edges of the box sections at all four sides thereof. The dies or

plungers

28, 29 are rounded off or provided with torous thickened portions at the point of pressure and are moved for instance by the `

rods

30, 31 or in another suitable manner. They may however also be stationarily or: spring actingly arranged. Either one ofthe pressing members may be preferably mounted on the feeding slide 32 for the box sections, while thepressing' members` opposite'therefrom may serve .as stops for' the advanced box sections. After the pressurebas been produced the box sections are assembled in the manner hereinbefore described. j

. ln Fig. 11 of the drawing a modification is shownin which the readily assembled

boxes

3, 4 after their discharge from the assembling device are movedthrough channels or pas.-

sages

33,34 disposed at right angle toveach other and the side walls of which .are pro- Yvided with resilient or spring

acting pressure rollers

35, 36. These rollers force the narrow sides of the boxes during their-travel vo' i in the first place against the longer side of the boxes, and then the transverse sides are all forced inwards, as clearly appears from Figures 11-13 of the drawing. 1
