Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has at least an endless flexible conveying connecting member, and the conveying connecting member has a large number of contiguously spaced intervals for conveying printing paper. The transport connecting body has a saddle-shaped mounting table, on which the printing paper sheet rides in a horse-like manner between the two driving apparatuses, respectively, and The present invention relates to a transport device for collecting and / or stitching printed sheets in a manner in which one rear entrainer abuts the rear edge of the printed sheet.

[0002]

2. Description of the Related Art A transport device of this type is known, for example, from European Patent Publication 0 881180 of the applicant. As transport equipment, single chains and so-called double chains are disclosed. This single chain has an entrainment device which is oriented at the same distance one after the other in the form of a finger and runs between the two articulations of the double chain in the transfer area. . The double chain likewise has an entrainer consisting of two identically spaced successive wings, in this case but in each case two laterally projecting wings. Also known are transporters which only have a double chain for collection and stitching.

[0003] The above-mentioned conveying apparatus is generally supplied with printing paper by a so-called printing paper feeder, and these printing paper feeders have two opening drums which are disposed after the conveying drum. In addition, the printing paper sheet feeder places the printing paper sheet on the transport device from above. At this time, the transport device and the sheet feeder are adjusted so as to be in harmony with each other, so that the printing paper sheet is respectively ejected between two successive carry-on devices. The rear entraining device grasps the ejected printing paper sheet at the rear edge portion, and entrains the printing paper sheet on the transport device. At high transport speeds, this ejection or placement of printed sheets is very important. This is especially true for printed sheets made of thin paper.

[0004] Furthermore, the printed sheets transported on the transport device are processed and marked, for example, by ink jet equipment. This takes place within a single chain or subsequently within a double chain. Within this double chain, for example, sewing is also performed.

[0005] On the transport device, different work processes are configured in the saddle area-the upper surface of the saddle and the side surfaces of the saddle-and these work processes require a sufficient free space in the work area.
Thus, in particular, when the release takes place with the subsequent ejection of the printing paper, the carry-on device for the printing paper precedingly running on the transport device does not interfere with the loading process of the next printing paper. Must be noted.

On the other hand, entrainers, for example on the sides of the saddle, are obstructive in the area of the ink jet station and should be kept as far as possible from the area for writing characters. In addition, the entrainer is located in the delivery area of the single conveyor, which transitions to a double collection chain.
An unobstructed entry should be made possible. In these circumstances, even during the suturing process in the transport device, double transport chains are used which extend over the entire processing length of the collecting and sewing device.

[0007]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an optimum and reliable processing of printed sheets when passing through different stations along a collecting section and / or a stitching section. To form a conveying device of the type described at the outset.

[0008]

SUMMARY OF THE INVENTION The object is achieved by means of the transport device described at the outset, in which the transport device is movably mounted on the transport articulation, one being mainly in the upwardly projecting position and the other being mainly in the lateral direction. The solution is achieved by being respectively adjustable between the protruding position.

The transport device according to the invention therefore has an entraining device which occupies at least two different states or positions. In this one position, the entraining device is oriented upwards and thus forms an empty space side by side with the printed product to be conveyed. In particular, this state is suitable for lateral processing of a printed product, for example, for addressing by an inkjet device. Conversely, in this second position, the entraining device is arranged laterally in this position, so that an empty space is formed above the ridge of the transport device. This situation is suitable, for example, in the area of the paper feeders, so that these paper feeders can be mounted close to the edge of the transport device. This position is likewise advantageous if, for example, thin printed sheets are to be transported, which have to be widely supported by the entrainer. The entrainers are therefore placed in this position, where optimal processing is possible. In other parts, the entrainer is mounted on a single chain or on a double chain.

[0010] If the entraining device according to another embodiment of the invention is mounted on the transport articulation so as to be pivotable with respect to the transport device in the lateral direction, the position can be adjusted simply and reliably. These entraining devices provide a particularly stable position when held in a position adjusted by a holding force, for example the elasticity of a spring. In that case, it is only necessary to overcome the holding force when replacing the position.

In the case of a driving device according to another embodiment of the invention, for example, when forcibly controlled by a toothed engagement, accurate replacement and guidance of the driving device is obtained.

In accordance with another aspect of the invention, the entrainer has two members, each of which is oriented essentially parallel in one position and oriented vertically upwards in one position. And project laterally from the transport articulation in the opposite direction at the other position. Both parts are then pivoted upwards or downwards like a butterfly wing. The above allows for a particularly simple control with a turning device. The diverter has, for example, two rods, which are provided so that both of these members are pivoted upward from an open position to a closed position.

The opening is effected, for example, by means of a wedge, in which both parts ride on this wedge and are then pivoted laterally and downwards. The diverting device described above can be implemented relatively simply in terms of structure, and a number of such stations are arranged one after the other along one transport device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a collection chain according to the present invention. Figures 6 and 7
Is a double chain with two parallel running articulations 2 and 3. This double chain is laid endlessly around a chain gear not shown here. Both articulations 2 and 3
Have a link chain 4 on which the mounting table 5 is detachably locked. The mounting table 5 is held, for example, via pins 7 of the link chain 4. Overall, the mounting table 5 forms a roof-shaped arrangement with a ridge A, which is indicated by a dashed line in FIG.

Two opposite mounting tables 5 each
a is the entrainer 8 consisting of two members 8a and 8b
Carrier device. Each member 8a or 8b engages in a slit 6 of the mounting table 5a and has a rotating shaft 15 in the lower area, which is supported at both ends by the mounting table 5a. The members 8a and 8b can thus be pivoted about the corresponding axis of rotation 15. At this time, these members are slidably fitted in the slit 6.

FIG. 6 shows one position of the entrainer 8 at the lower right, at which point both members 8a and 8b protrude laterally. As FIG. 7 clearly shows, the laterally chamfered surfaces 20 each form a stop for the members 8a and 8b. This stop limits further pivoting movements downward. A tension spring 18 acts on each of the members 8a or 8b, the tension spring being spaced at one end from the rotary shaft 15 by a member 8a.
Alternatively, it is fixed to one of these mounting tables 5a by 8b and by the other end. These tension springs 1
8 are mounted, these tension springs
You get nervous when you flip up a and 8b. Thus, the tension spring 18 stabilizes the members 8a and 8b in that position shown at the lower right in FIGS. The tension spring 18 shown here can be replaced by a leaf spring or a magnet.

FIG. 6 shows a second position of the entrainer 8 in the upper left, in which the members 8a and 8b are oriented upwards, each projecting above the ridge line A by one upper end. ing. From this position, the members 8a and 8b
It can be turned again into the position shown in the lower right of FIG. Here, too, the members 8a and 8b are pivoted around the rotation axis 15, respectively. This position, where both members 8a and 8b project upwards into that position, is likewise stabilized by a tension spring 18.

FIG. 7 shows the entraining device 8 in one position in cross section and the entraining device in the other position in external view. Here, similarly, the printed paper sheet 12 riding in a horse-like shape on the transport device 1 is shown. Here, the transport device 1
7 moves from top to bottom in a direction perpendicular to the plane of the drawing in FIG. 7, so that the printing paper 12 is conveyed by the entrainer 8 shown here in cross section. FIG.
As will be clear, the members 8a and 8b
Act with an interval on the fold line 12a. This allows a wide support to stabilize the printing paper 12.

To adjust the entraining device 8, a control device 10 having two stations 10a and 10b shown in FIGS. 1 and 2 is provided. This station 10a has two rods 11, which are provided side by side in the transport device 1,
Further, when the transport device 1 is moved in the direction of the arrow 19, the entraining device 8 rides on the control region and is turned. The other station 10b is ridge A so that the members 8a and 8b respectively ride on the lateral control surface 21 and are pivoted laterally downward.
And is formed in a wedge shape. The stations 10a and 10b are adjustable and, of course, positioned so that they occupy an advantageous position in the area in which each of these entrainers 8 is located. Embodiments in which a number of stations 10a and 10b are provided are also conceivable. Also, other means known in this industry that can change the direction of the entraining device 8 are possible.

FIGS. 1 and 2 thus show a single collecting chain 1 ′ which merely comprises one link 9 with one link chain 4. Here, the mounting tables 5 ′ are made of one member and likewise are detachably locked on the link chain 4. Similarly, the mounting table 5a 'has a laterally oriented slit 6' in which the entrainer 8 'is engaged and pivotally fitted therein.

FIGS. 3, 4 and 5 show sectional views of the single-collection chain conveyor 1 ', FIG.
And FIG. 4 shows the other position of the entrainer 8 '. FIG. 4 clearly shows that in the position shown here of the entrainer 8 ′, an empty lateral space is formed, whereas in the case of the position according to FIG. Is formed on the fold 12a. The position according to FIG. 4 is therefore particularly suitable for addressing,
On the other hand, in the position according to FIG. 3, a paper feeder, not shown here, is moved very close to the ridgeline A. The illustrated position of the entrainer 8 'is stabilized by a tension spring 13, which in the case of FIG.
it only acts on a '. Both members 8a 'and 8b'
However, this member 8b 'is connected via the toothed portion 14 to force the same or opposite pivoting movement.
a 'is connected to the corresponding toothed portion. In this case, the control device 10 can be configured more simply, because
This is because here one of the two members 8a 'or 8b' only has to be controlled. Both parts are pivoted relative to one another in each case in a synchronous manner.

The two members 8a 'and 8b' are basically formed in a finger shape as can be seen. Here, however, other wider or longer embodiments are also conceivable. An embodiment is also conceivable, in which case the entrainer 8 'has only one element. Thus, in the embodiment according to FIGS. 4 and 5, the members 8a 'or 8b' are omitted.

FIG. 5 shows a section through the transport device 1 with the entraining device 8 'pivoted out, so that an empty space is formed above the fold 12a.
