DE8010071U1 - DEVICE FOR TREATING BOOKS - Google Patents

Abstract

The invention relates to a device for treating books comprising a frame and two belt conveyors, whose proximal faces are located in parallel planes adjustable towards and away from one another, said faces being fixed in the transverse direction in the plane of each face. The device according to the invention comprises a roller conveyor comprising a large number of freely rotatable rollers (11), whose parallel rotary axes are at right angles to the planes of the proximal faces of the belt conveyors, the shafts being displaceable by spring load towards said faces.

Device for handling books

The innovation relates to a device for handling books, provided with a frame and two belt conveyors, their facing strands in parallel Layers lie that are adjustable in the direction of each other and from each other, which runs in the transverse direction are fixed, which lies in the plane determined by each strand. One such device is known in bookbinding and can be used with organs for applying glue to the spine, organs for Rounding a book block or organs for gluing a cover around the block can be combined. In the latter Pail is usually the envelope with so-called hotmelt Adhesives applied because these adhesives have sufficient adhesive strength practically immediately, to hold the cover on the book block. Because these adhesives have disadvantages such as inflexibility and brittleness, other types of glue are sometimes used, such as Vinyl emulsion glue, preferably the same, but requires a rubbing process after leaving the device, in which the covers are arranged around the book block. For this rubbing process, the books from the aforementioned Device taken out and placed in a press, in which the books as long as a certain Pressure should be held until the glue is adequate

Adhesion has developed to hold the cover around the book block. Then the books taken out of the press and dried.

The pressing process is labor-intensive and is

j 5 homely the limiting factor in the speed of production .

With the innovation, a device of the type described above is proposed which makes it possible carry out the rubbing process at the same speed as the previous processes and at the same time to carry out this process continuously according to the preceding device. To this The purpose of this device is to use a roller conveyor with a large number of freely rotatable ones Characterized roles, whose parallel axes of rotation at right angles to the through facing each other Runs of the belt conveyor are specific levels and are spring-loaded towards these runs, movable are stored.

In order to be able to constantly exert a relatively large amount of pressure on the spine of the books, it is preferable to use the rollers of the roller conveyor are loaded by separate springs.

With regard to the possibility of a timely changing spring force, the spring load is adjustable in a preferred embodiment, so that a change in the spring force can be compensated for.

A particularly good effect is achieved if the effect exerted on the spine of the book by the rollers Pressure gradually increases as it passes through the device, for which purpose preferably the spring tension or the rigidity of the spring load increases in the conveying direction.

The fixation of the belt conveyor in the transverse direction can take place in a conventional manner by moving the conveyor belt is provided on the back with one or more 'projections through in the longitudinal direction The FÖrdeneis are guided tours. In In a very simple embodiment, however, each belt conveyor is composed of a number of V-belts, which are guided over appropriately grooved support rollers fixed in the axial direction. In this Context, it can be noted that a belt conveyor should be understood to mean any conveyor that a flat conveying surface is defined so that the belt consists of a closed or perforated flat Band made of flexible material, made of articulated joints flat plates or from a number of parallel

running straps or narrow ribbons.

To adapt to different book thicknesses there is at least one belt conveyor in the direction to and from the others movably attached in the frame. To achieve sufficient entrapment in the case of a less critical one Adjustment of the distance between the two facing strands of the belt conveyor are at least the support rollers of one of these belt conveyors in a direction perpendicular to that through the same supported strands resiliently mounted in the frame.

The innovation according to the device can be used both as a separate device behind a device for Assembling book blocks and arranging covers are set up as integrated in the same be.

The innovation thus also relates to a device for arranging a cover around a book block, provided with a conveyor for feeding a book block and organs for folding an envelope around this book block, which device by a further in the conveying direction than the organs for folding an envelope arranged device, as described above, is characterized.

The innovation is based on a "preferred embodiment with reference to the Drawing described in more detail.

! Fig. 1 shows a vertical longitudinal section of the device according to the innovation,

Fig. 2 is a plan view and

3 is a front view with parts broken away.

In the figures, an elongated frame 1 is shown in which four vertical axes 2 are mounted. At the upper ends of these axles, grooved pulleys 3 are wedged, over which two sets of V-belts 4 run in the longitudinal direction of the frame. The facing strands of both sets of V-belts are supported at the rear by grooved support rollers 5, the vertical axes of rotation of which are mounted in longitudinal members 6, 7. One longitudinal carrier 6 is rigidly connected to the frame 1 nit, while the other longitudinal member 7 disposed transversely displaceable i ^m frame 1 and is loaded in the direction of the fixed longitudinal beam 6 by means of compression springs. 8 In this way, books can be clamped between the two belt conveyors with a certain clamping force.

In the embodiment shown, there is

From each pair of pulleys 3 is one with one common to both Motor 10 can be driven.

In the frame part 1, the belt conveyor is a roller conveyor below the two facing strands or a roller conveyor, consisting of a large number of rotatable rollers 11, whose parallel axes of rotation are at right angles to the parallel planes determined by this strand. The axes mentioned are movably mounted in vertical slots in the frame part 1 and are supported by compression springs 12 charged upwards. The tension of these springs can be adjusted with the aid of adjusting screws 13.

If a book block with a cover glued around it, through the device using the V-belt is guided, the downward-facing back is subjected to constant pressure by the rollers 11. the Implementation speed and the length of the device must be adapted to the type of glue that the glue has developed sufficient adhesive strength when leaving the device, the cover on the book block to hold on.
