The invention relates to a packaging machine for packaging books and the like, in particular for postal items, which machine comprises a book feeding unit for feeding books or the like to packaging units in which the paper, cardboard and / or other layers forming the package are wrapped around the book, packaging material feeding units, gluing unit necessary points in the packaging materials, a package sealing unit, and an electronic control unit for controlling the functions of said units.

The problem with the bulk mailing of books in particular has been that the packaging has had to be carried out mainly as a labor-intensive, time-consuming and costly craft, due to the fact that machines suitable for fully automatic and fast book packaging have not yet been developed.

The object of the invention is to provide a new type of packaging machine for packaging books or the like in a completely different way from the previous packaging technology, so that a very high packing speed is possible, e.g. about 1 packing / second.

This object is achieved mainly on the basis of the features of the invention defined in the appended claim 1.

The subclaims set forth the most preferred embodiments of the invention.

In the following, the invention will be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a block diagram of a packaging machine according to the invention.

Figure 2 schematically shows a book feed unit.

Figure 3 schematically shows the protective wrapper feeding unit and its operation.

Figure 4 schematically shows the wrapping unit of the protective wrapper and its operation.

Figure 5 schematically shows an address card feeding unit.

Figure 6 schematically shows a protective board feeding unit.

Figure 7 schematically shows a gluing unit.

Fig. 8 schematically shows a prestressing and folding unit of a protective board and Fig. 9 shows a sealing unit of a package.

In Figure 1, the numbering of the blocks corresponds to the numbering of the figure showing each block separately, so that the description of the operation of the blocks appears in connection with the description of Figures 2-9. In addition to these actual operating units, there are optional feed units 10 and 11 for feeding any member magazines or the like that may be included in the package, and a further processing unit 12 which performs counting, sorting (e.g. by postcodes), onward transport, etc.

The control, monitoring, alarm and calculation center 1 is implemented as an electronic cue control system that controls all the functions of the various units 2-12 of the machine. This control of functions includes start, monitoring, reset, synchronization to the next step, calculation, notification of end of material, etc. Since the control unit 3 51578 can be implemented using conventional control electronics known from other similar devices, its detailed implementation is not affected in this context, since the invention in this application is the operation and mutual arrangement of units 2 to 9, which are described below.

Figure 2 shows a book feed unit 2 into which the books to be packaged slide or are conveyed by a conveyor into a stack of a few books. From this stack, one or more bottom books are pushed into the protective wrapping unit 4 by a pusher 13 between the units 2 and 4, or rather immediately into the front of the unit 4, a strip-shaped protective wrapper is fed from its feeding unit 3.

Figure 3 shows a protective wrapper feeding unit in which the drawing rollers 14 continuously pull the wrapper from the roll into a storage shaft 15, which always has material for at least one book (step a). The vertically reciprocating catcher 17 pulls down the wrapper released from the upper holder 16 (steps b and c). The protective wrapper engages the side transfer device 18, cutting it below the lower holder 16 (step d). The protective wrapper is then transferred by means of a side transfer device 18 in front of the wrapping unit 4.

Figure 4 shows the wrapping unit 4 of the protective wrapper. The book pushed by the book feeding unit 2 and the wrapper fed by the protective wrapper feeding unit 3 protrude into the wrapping unit 4 between the front press 19, the rear press 20 and the folding roll 21 (steps a and b). The folding roll 21 and the protrusion 22, the movement of which is tied to the movement of the folding roll 21 and the front press 19 rise (step c) * In step a, the adhesive applied to the lower end of the protective wrapper adheres to one end of the wrapper when the end provided with the adhesive of the wrapper self-corrects. The movement-connected push rod 22 of the folding roll 21 inserts the book wrapped in the protective wrapper between the conveyor belts leading to the protective cardboard prestressing and folding unit 8 (step e).

In Fig. 5, the address card feeding unit 5 feeds the account address card into the gluing unit 7.

4,51578

In Fig. 6, the protective board feeding unit 6 feeds and at the same time nibbles (step a) to the gluing unit 7 of the protective carton having either a pre-stamped or a stamped window for the address card (step b).

The gluing unit 7 shown in Fig. 7 applies the glue to the protective cardboard for gluing the protective wrapper around the book I and for attaching the address card II (step a). Further, the gluing unit aligns the .address card with the protective paperboard (step b) and transfers the paperboard and the address card adhered to it (steps c and d) to the cardboard bias and folding unit 8.

In Fig. 8, the carton bias and the folding unit 8 align the book with the protective wrapper over the half-carded half of the protective carton (steps a, b and e). Thereafter (step d) the other half of the paperboard is bent prestressed onto the book with a folding rod so shaped that when bent the paperboard half first bends diagonally into a trough, increasing the bending stiffness of the board with its trough-like part and starting to bend strongly against the book. As the package continues to move relative to the folding bar, the folding bar eventually rests on the cardboard half bent over the book immediately adjacent to the folding point of the cardboard. Using conventional conveyor equipment, the package is transferred to the sealing unit 9.

The closure unit 9 shown in Fig. 9 performs the closure of the package with one or two stapling hooks or the like (step a). The location of the staples has been chosen so close to the edge of the book that the protective board is tensioned relatively tightly around the book. The finished package is transferred from the sealing unit (step b) to the further processing unit 12.

As this is a completely new type of packaging machine, the description has not been extended to the structural details of the parts of the machine known per se.
