Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is a book block conveying device, which comprises a book block conveying path for vertically moving book blocks one after another forward in one flow; This is followed by book block flow switching means for dividing the transport flow of book blocks into two flows, and two accumulation paths arranged after these.

BACKGROUND OF THE INVENTION A device is known from East German Patent No. 31 604 which divides the transport stream of book blocks into two streams and subsequently accumulates the book blocks, according to which a bookbinding machine, e.g. The book blocks taken out from the paper sorting machine are divided into two conveyance streams by a sheet switch and are accumulated on two separate accumulation shelves. The use of such a book block transport device appears to be advantageous for connection to folding and glue binding machines, especially for drying and stacking processes.

(Problems to be Solved by the Invention) However, the above conventional example requires two complete drying devices or two complete book block shelves, or both, which not only increases costs but also increases costs. The disadvantage is that it requires a lot of space for integration.

The problem that the present invention seeks to solve is therefore to eliminate the above-mentioned drawbacks and to minimize the space requirements for the stacking shelves that require book blocks coming out of the folding machine and/or the gluing machine. However, in an economical manner, the book blocks can be delivered to a book block drying device and/or a book block shelf.

(Means for Solving the Problems) The problems in the prior art described above are solved as follows according to the present invention. That is, according to the present invention, there is provided a book block transport path that transports book blocks one after another in a vertical state in one flow;
A book block conveying device comprising: a book block switching means for dividing the conveyance flow of the book blocks into two partial streams following the conveying path; and two accumulation paths arranged downstream of the switching means. Two stacking paths are arranged in parallel in the transport direction of book blocks, and the book blocks 1, which are alternately pivoted from the center of the book block transport path toward both outer sides, are moved toward the two stacking paths. A book block pusher is provided which allows the book block to take on a scale-shaped inclined arrangement.

A particularly advantageous constructional embodiment in this case is for the book block switching means to be designed as a pivotable belt conveyor. In this case, one of the rollers pivoted at the free end of this belt conveyor can be pivoted on a pivot member linked to the associated support rack. This causes the book blocks to be transported at the conveying speed of the belt conveyor.
The material is alternately delivered onto two accumulation paths that circulate at a slower rate than this transport speed.

In order to prevent the scalloped book block from tipping over, the outer guide plate can be bent inward at its lower part in the book block push-in area. As a result, the book blocks, which are tilted in a scale-like manner by pushing the book blocks, are slightly tilted in the stacking direction and lean against the stack. This effect can be used independently of the book block press in its upper press area, as well as the press ring, as well as its lower inward bending of the outer guide plate.

(Example) Examples of the present invention will be described below with reference to the accompanying drawings.

The book blocks 1 are conveyed one after another at a small distance while maintaining a vertical posture by two plate-like chain conveyors 2 and 3 forming a conveyance path.
The plate chain conveyors 2, 3 pass the book block 1 to two adjacent belt conveyors 4, 5. These belt conveyors are suspended on left rollers 6, 7 and right rollers 8, 9, respectively. These four rollers 6 to 9 are each attached to support racks 10 and 11 by support shafts. support rack 10,
Reference numeral 11 denotes local fixing holders 13, 14 attached to the frame bodies 12 of the plate chain conveyors 2, 3 by the spindles of the left rollers 6, 7 when viewed in FIGS. 1 and 2 on the left side. Pivotably mounted on the shaft. The support racks 10, 11 are therefore pivotable together with the belt conveyors 4, 5 about the pivots of the left rollers 6, 7. The belt conveyors 4 and 5 are driven by a drive belt 15 and a plate chain conveyor 2 and 3, respectively.
16 to the left rollers 6 and 7. An endless belt conveyor 17 runs between rollers 18 and 19 below the belt conveyors 4 and 5. The belt conveyor 17 is connected to the plate chain conveyors 2, 3 in a manner not shown.
and the drive is combined. The belt conveyor 17 is
It serves to support the book blocks 1 on the belt conveyors 4,5.

Below the belt conveyors 4, 5, in the frame 12, with respect to the straight conveyance path (plate chain conveyor 2,
A push rod 20 is pivoted at right angles (with respect to 3) so as to be movable in the horizontal direction.

Guide rods 21 and 22 are linked to this push rod, and the guide rods are linked to support racks 10 and 11 of the belt conveyors 4 and 5. push rod 2
0 has a drive device, not shown, consisting of a cam and a linkage for moving the push rod back and forth in synchronization with the book blocks 1 being fed. As a result, the book blocks sent by the belt conveyors 4, 5 are alternately shifted to the left and right. The belt conveyors 4, 5 thus form book block switching means. The guide rod 21 is equipped with an adjustment device. Thereby, the distance between the belt conveyors 4, 5 is adjusted according to the thickness of the book blocks 1 to be conveyed.

The plate chain conveyor 2 must also be adjusted relative to the plate chain conveyor 3 by means of a manual actuator, not shown.

The entire book block transport path is adjusted to the thickness of the book blocks placed during processing.

The provision for length adjustment of the guide rod 21 also serves as a protection against overload when passing extremely thick book blocks. For this purpose, a compression spring is built into the guide rod 21.

Downstream of the book block switching means formed by the belt conveyors 4, 5, there are stacking racks 23, 24 and guide chains 25, 26 and 2 which are attached to their side chain wheels.
7, 28 and a continuously moving accumulation path 33,
34 continues. The conveyance speed of the accumulation paths 33, 34 is significantly lower than the conveyance speed of the belt conveyors 4, 5. This conveying speed depends on the size and thickness of the book blocks 1 being fed and is determined in harmony with the conveying speed of the belt conveyors 4, 5. The accumulation channels 33, 34 are delimited by two fixed inner guide plates 29, 30 and two adjustable outer guide plates 31, 32. A book block 35 is placed between these two accumulation paths 33 and 34.
is pivotally supported. This book block pusher 35 is driven by a known method in synchronization with the conveyance of the book blocks, and pushes the book blocks 1 that have been alternately sent to the stacking paths 33 and 34 from the belt conveyors 4 and 5 into a scale-like inclined arrangement. do. This book block pusher 35 can also be controlled by the book block itself in a manner not shown, for example by a photocell or a sensing switch. The same applies to the book block switching means. FIG. 1 shows that the book block pusher 35 has finished pushing the last book block 1' into the stacking path 33 and is still in contact with it, but the next book block 1'' is just in the stacking path. 34 is about to be delivered.

In FIG. 1, the intermediate position of the book block pusher 35 is additionally indicated by dash-dotted lines.

In order to prevent the pressed book blocks in a scale-like tilted arrangement from tipping over when the book block pushers 35 are pivoted back in the opposite direction, the outer guide plates 31, 32 are arranged as shown at 36 in FIG. It may also be bent inward at its lower part. The pushed and tilted book blocks 37 are slightly tilted towards the formed book block stack. This effect is
Push the pressure ring 38 into the arm 39 of the book block push 35.
This can be further strengthened by mounting it in the upper area of the book block press (FIG. 3). The press ring 38 is attached to the arm 39 of the book block press 35 in the upper book block area.
presses the incoming book block 37 towards the scale-shaped book block more forcefully than it does in the lower book block area. Furthermore, the risk of the book block 37 falling over can be eliminated by an additionally mounted adjustable retaining spring 40.

In FIGS. 1 and 2, the right roller 8
The mounting portion may be modified so that it is pivotally supported on the right support frame 10 by the pivot member 41 (the fourth
figure). The pivot member 41 is linked to the support rack 10 at a pivot shaft 42, and the book block is fed between the rollers 8, 9 by means of a tension spring 43, which is connected to the support rack 10 on the right side and to the pivot member 41 on the left end. 1 is pivoted about the pivot axis 42 as soon as it leaves the belt conveyors 4, 5 (FIG. 5). The book blocks 1 are thereby moved a little further forward with the conveying speed of the belt conveyors 4, 5 and onto the stacking shelves 2, which circulate even more slowly than the belt conveyors.
3, pressed on 24, resulting in book block pressed 3
5 can immediately participate in the book block transport area.

Before the accumulation of book blocks is started, corner plates are placed one by one on the accumulation paths 33, 34 in a known manner. Advantageously, the corner plates are held by permanent magnets. Corner plates prevent the initially stacked book blocks from falling over. The corner plates may be removed after the collection of book blocks is completed.
After that, the book block collection will automatically become independent.

The book block conveying device according to the invention, in which scale-shaped book block stacks are formed on the stacking paths 33, 34, is particularly suitable both for book block drying installations and for displaying book blocks. For use in book block drying installations, the drying equipment can be arranged around the collection channel, ie the collection channel can be passed through the drying equipment. Regarding the drying equipment for drying the spines of book blocks, the heating element is placed under the stacking paths 33, 34, i.e. on the stacking rack 2.
Fixedly placed below 3 and 24. In this case, the collecting channels 33, 34 can likewise be completely enclosed.

When the book block transport device is used as a book block stacking installation, the stacking channels 33, 34 serve directly as stacking and removal channels for manual removal of the stack of scale-shaped blocks.
