PATENT OFFICE.

The present machine is used for the production of square, paper-covered Boxes made of cardboard, cardboard or any other suitable material.

The machine is divided into two main parts separated from one another, the upper one, in which one a punching device knocks out the material in question in the appropriate form, and the lower, in which the knocked out piece is shaped into a box and kept in this form is covered with paper all around.

The attached drawings show:

The set-up and operation of the machine are explained below.

About the sliding path α (Fig. 1 and 2) by means of the transport rollers a ^l a ² (Fig. 1 and 2), which by the on the drive shaft 1 (Fig. 1, 2 and 3) seated gear ν and by the translations v ¹ a ³ a * a ⁵ (Fig. 1 and 2) are set in motion, the cardboard or other material strips to be processed α ^η (Fig. 1 and 2) under the curve b (Fig. ι and 2) and the lever b ^l moved punch έ> ³ pushed against the protruding cross bar a ^ü. The transverse nut a ^s located on the transport roller a ¹ (FIG. 1) holds the strip a ' ¹ in place at this moment, and the descending punch £ ³ knocks out a piece of it in the cross shape corresponding to the folded box.

The cam plate d (Fig. 1 and 2) has already previously guided sideways the lever d ^l d ' ² , which can be rotated about d ⁹ in the horizontal direction, with the levers d ³ d ^a suspended from the latter and their guide e , by the on the mentioned cam plate located projection d ^{1 slid} past the fixed point d ^s , whereby the same on its axis t ^l (Fig. 2) was shifted laterally.

The knocked out cruciform piece of cardboard falls through the die ö ⁴ onto the square die c (Fig. 1, 3, 4, 5, 6, 7, 8 and 9). The side parts of this die, which exactly match the shape of the one to be produced

Corresponds to boxes, form the springs c ² screwed tightly on the sleeve c ¹ , while the top plate c ⁴ attached to the vertical shaft c ³ forms the bottom of the same. The pusher d ³ (Fig. Ι, 5, 7 and 9) moved sideways at the beginning of the work now again over the die c, goes down and produces the box shape by pushing the knocked out piece of cardboard into the die. This movement is mediated by the cam disk d ^b and the lever d ' ² (Fig. I, 2, 5, 7 and 9).

The paper strip ρ , which is used for gluing the box and is moistened on one side with some kind of adhesive, comes from any paper roll over the guide roll ^ (Fig. 1 and 3) between the transport rollers z'z ¹ , the former with the ratchet wheel k on a common axis sits. By means of the cam disc A- ¹ , the lever k ' ² and the pawl k ³ (FIGS. 1 and 3), the ratchet wheel k is now rotated by a few teeth and so the end of the paper strip ρ, which was previously guided through the sheet metal guide i , up to the clamping lever / (Fig. 3 and 4) brought.

In the middle of the cam disk m ^l and the lever in (Fig. 4), the rod m * attached to the latter and sliding in the guides m- m ³ pressed against the lower arm of the lever /, whereby the spring Z ¹ compressed and the upper arm of the lever was held back by the die c . However, at the moment when the lever m slides down from the hump of the disc m ¹ , the spring m ⁵ pushes the rod mz ⁴ from the lower arm of the lever / (Fig. 4). This also causes the spring / ^λ to expand, presses the upper arm of the lever / against the die c and thus clamps the advanced paper strip ρ , whereupon the former with the help of the eccentric η (Fig. 1, 3 and 4) of the ratchet wheel n ^l and the gear drive 0 o ^l o ' ² o ³ executes a complete rotation around its vertical axis, in which the paper strip ρ lies around the die c (Fig. i, 3, 5, 6, 7, 8 and 9) .

As the rollers s slide down from the cam disks s on their first step s ³ , the roller levers s ^l push the bars q sliding in the tracks q ' ² against the box held by the springs c' ² and the top plate c ⁴ (Fig. 1, 3, 4, 5, 6, 7, 8, 9 and 10). These bars consist of the lower part q , which is provided with a slide guide, and the upper part q ¹ , which slides back and forth in this guide. ^{A spring (3)} arranged horizontally between these two parts tends to move them apart in this direction, the upper part approaching as closely as possible the central axis of the machine.

And therefore the rollers s' ² to the gradations s lapse ^3, present this upper part q ⁱ of the latch against the side walls of the die c, where they q with its projecting edge of * the top protruding edge of the laid around the same paper strip ρ via Fold the edges of the box standing in the die (Fig. 7). Then the cone d ^ pressed down by the cam disc d and the lever d ¹ (Fig. 1, 5, 7 and 9) pushes back the upper part of the bolt q , in that it lies against their projecting lugs (Fig. 9). At the same time, the pusher d ⁶ lies in the box, wrapping the previously folded edge of the paper strip.

Moved by the cam plate g, the forked lever g ² , rotatable around the pin g ¹ (FIGS. 1, 3, 4, 5, 7 and 9), presses the sleeve c ¹ with the die c and the clamping lever / down. Here, the slide springs ² c 'to the Seitenwa'nden down the carton, while this itself, c on the head plate ⁴ of the vertical shaft ³ c standing and the lying in its pushers d ^{3 e} d maintained, remains in its previous position, and so laterally becomes free (Fig. 9).

The paper strip ρ lying all around and already wrapped in the top is now cut off by the toggle lever r ^l (Fig. 3 and 4), ^{rotatable about r 3} , which carries the knife r and is actuated by the cam plate r ² under the action of the spring r ⁴ .

As the rollers s ² (Fig. 1 and 4) ^{step under the action of the springs s 5} on the last gradation s ^{l of} the cam disks s , the roller levers s ¹ now bring the protruding edge q ^{5 of} the lower part of the bolt q against the protruding one below Edge of the paper strip, this is folded under, and when the bars press the whole box together evenly, this gets its final shape (Fig. 9 and 10).

So that the latch on the side of the lever / is not hindered in its action by this, the lower part of this latch is provided with a recess q ^K , into which the end of the lever / lies when the bolt is pushed forward (Fig. 6, 8 and 10).

As the rollers s' ² step back to the level of the cam disks s , the roller levers s ^J pull the bolts q back from the box. Thereupon the levers d ¹ d ' ^2, which can be rotated in the horizontal direction about d ^9, with the pushers d ³ d ^e suspended from the latter and their guidance e through the cam disks d respectively. d " ^ü lifted and returned to their initial position (Fig. 1).

Since the handle d ^ü fits exactly into the interior of the box, the latter remains attached to the box and is thus lifted off ^{the plate c 4 and}

holder led. At this moment the pressure previously exerted on the cone d ⁱ by the lever d ^l diminishes, so that the latter together with the pusher d ⁶ connected to it is lifted up by the expanding spring d ¹⁰ (FIGS. 1, 5, 7 and 9) while the pusher d ³ acting against the bottom of the box prevents it from following this movement. The pusher d ⁶ thus emerges from the box, and since the pusher d ^{s is} about Y ₂ mm smaller than d ⁶ , it cannot hold the box in place. The box is free on all sides and falls into the container below.

Thereupon the bushing c ¹ with the clamping lever / and the die c attached to it also steps back into its initial position as a result of the expansion of the spiral spring g ^3.
