Description

Device for producing and closing the bottom and lid of Folding boxes or the like. The invention relates to an apparatus for manufacturing and closing of folding boxes from a blank, as shown in Figs. i and z can be seen. The same is delivered in the folded state according to Fig. I. Fig. A shows it diagrammatically in the open state.

a are the box walls, which are already connected at their edges. b and c are attached flaps, which by turning at a right angle a Create a double bottom and a double lid. From Fig. 8 is graphically the finished one Container can be seen and in particular the adhesive tape d, which is on the Folding together forming open joints and creating a cohesion of the whole container.

The manufacture and sealing of the folding boxes from these raw pieces specifically for use as bottle boxes or strips has been done so far by hand. The purpose of the invention is to reduce manual labor to a minimum.

The entire device consists of two individual devices, one for the production of an open, empty box with a closure at the bottom and one another to close the lid of the filled box. Both devices have a technical basic idea, but are different in another direction according to the diversity of the work process for the two sub-purposes, Closing the bottom and closing the lid.

The two bottom flaps on the blank according to Fig. Z are bent over, and in this state the piece is put over a table so that the bent Base parts rest on the table. These floor parts are held down by a mechanical hold-down device pressed onto the table so that the edge is flush with the edge, and then become put the adhesive strips over the edges by hand. That will be with the other two Parts of the floor repeatedly. Now the still open container is lifted onto the Put the bottom and fill it. The closure of the container through The lid is formed in basically the same way. The filled container is also placed on a table, the lid flaps are bent over by hold-down devices held in their closed position and now glued in the same way. But here is There is also an additional facility because the filling of the box is under pressure easily causes a bulging of the side walls and thus a partially wider one Removal of the top edges of the side walls than the size of the lid to be formed is equivalent to. That's why we're here special side pressure organs are still planned, which flatten these bulges again.

There are a lot of nesting machines to the credit. ' place and seal of boxes: .rbej knows, but none of which of the described blank goes out. These also show details of correspondence with the subject matter of the invention. In particular, it is known from a blank, which the box walls already coherent .contains, a pressure on the lid and the side walls by means of a foot lever to be exercised by suitable pressure organs. There are also table-like devices known which serve as an abutment for folded flaps in the formation of the bottom.

Also the operation of holders by kicking them in other packaging processes is known, as is the actuation of side pressure organs by inclined surfaces.

The design of the two devices goes from the drawing in detail emerged. From Fig. 3, q., 5 and 6 in particular the device for forming the Can be seen at the bottom of the container.

f is the work table, which is on a column / 'on a rotatable Frame/? is supported. The blank is placed on it by hand in the dotted position turned up. g are the hold-down devices, which are hinged to the columns g1 at g2. They are pulled down by tie rods g3, which via the springs g4 with an up and down pivotable frame g5 are connected. This frame g5 is at g6 hinged and provided with a kick g '. Springs g $ bring the hold-downs back to its rest position while lifting the frame g5.

After two flaps are pressed down and glued, the Table f rotated through a right angle to the worker without changing its position the gluing of the two now to be put down and held down flaps to enable. To bring about this rotation, the column f1 is on a turntable la supported, which rotate by means of the rollers hl on the fixed base plate h2 can. A catch S of any known type secures the low position of the frame g5 during the gluing work. The catch according to Fig. 6 consists of one under the Pressure of the spring k1 standing snap piece k, which is hinged at k2 and useful hits a section of the kick g '.

The device for closing the filled container is different - initially in the overall arrangement only through the lower position of the table f the height of the container from the previous facility and does not require any further description, since the ": hold down of the floor pieces by the hold-down g and all associated Measures are carried out in the same way as described.

In addition, a cone is axially movable on the support f1 which moves downward when a frame g5 is depressed. n are the side pressure levers, which are hinged to the table f at n1 and on their top the pressure pieces ya = and at their lower end the sliding rollers n3. It is it can be seen that when the cone went down, the pressure pieces hit the side walls of the container @ and press in any bulges again and the upper edges bring into the correct position for the formation of the sealing cap.

PATENT CLAIMS: i. Device for the production and closing of Bottom and lid of folding boxes o. The like. With finished side walls to which connect the bottom and cover forming flaps that overlap when folded, which are closed by hand with adhesive strips, characterized by that it consists of two sub-devices, one of which to form the bottom the empty folding box pressure arms (g) to hold the flaps (b, c) in the closed position on a table (f), the other to close the lid of the filled folding box just such pressure arms (g) and also a, but lower lying table (f). contraption for closing the lid of folding boxes according to claim i, characterized in that that, in addition to the upper pressure arms, lateral swingable holding arms are arranged, which are swung into the working position by inclined surfaces or the like, wherein Attack the holding points of the arms around the top of the packaging and both Pairs of arms (g, n) can be swung out by the same foot stroke. 3. Overall device according to claim i, characterized in that the sub-devices are mounted on a base plate are rotatably mounted.
