Description

[Detailed description of the invention] [Industrial field of application] In order to transfer unbound book blocks consisting of loose sheets or signatures from a collating machine to an overlock binding machine, a transfer between these two machines is provided. A system is provided, and the transfer system is responsible for passing the book blocks coming from the preceding machine to the succeeding machine at regular intervals. The invention relates to means for this transfer to a subsequent machine.

[Prior Art] A delivery system is known, for example from West German patent DE-OS 3445928, which is placed between a collating machine and an overlock binding machine semiconductor device, which has a mounting stand for book blocks. and a belt-type feeding conveyance path for feeding the book block between them, and the belts on both sides of the feeding conveyance path are moved by an actuating means relatively in the direction of opening or closing the gap. The opening or closing control is such that while the preceding machine is decelerating and the book block coasts into the delivery system, the belt is closed between the two belts to prevent the book block from being fed further. is open, and when the preceding machine is switched on again, the space between both belts is closed so that the book block is transported further ahead at a predetermined cycle that matches the succeeding machine.

The feeding system in the collating machine and the conveyance of the book block in the introduction device of the double-binding machine are, as is known, hinged on a chain which moves the book in a circular motion. This is done by a carrying buddy who gets behind the block and pushes the book block while keeping it upright with its back supported by the book block stand.

The book block coming from the collating machine is picked up by the belt of the transfer system, which is driven at a higher speed, and is fed into the book block mount in the double binding machine semiconductor device. The book block is then accelerated again by the carrying companion from its rest state to the transport speed of the introducing device. In this case, the carrying companion hits the unbound book block consisting of loose sheets or signatures with a large relative speed, so that on the one hand, between the book block and the lateral guides and with the platform, and on the other hand, the individual Due to the difference in frictional forces between the loose sheets or signatures,
It happens that sheets or signatures that were previously precisely aligned become displaced relative to each other. This problem occurs particularly in the area of high-speed driving, but also occurs when the book block is subjected to an overturning moment due to its large format and the low engagement point of the carrying companion.

[Problems to be Solved by the Invention] An object of the present invention is to avoid the above-mentioned interlayer, and even when the machine capacity is further increased, book blocks are transferred from the preceding machine to the succeeding machine without the need for paper sheets or folds. It is an object of the present invention to provide a semiconductor device of the above type, which can be transported without any trouble while maintaining a uniform state.

[Means for Solving the Problem] According to the invention, this problem is achieved in that in the inflow region of the subsequent mechanical semiconductor device, a feeding device is provided for receiving the upright book block from the transfer system and transporting it further. The solution is that the lever feed device is driven to the introduction device with a slower speed compared to its carrying companion. Preferably, the feeding device comprises a roller conveyor having a plurality of driven and rotating rollers.

With the introduction device according to the invention, the conveyance of the book blocks of the bookbinding machine, consisting of loose sheets or signatures, from the preceding machine to the succeeding machine takes place in the form of a transfer between streams. The book blocks discharged from the transfer system maintain a fixed transport speed, so that they can be picked up during the flow by the carrying companion of the introduction device. Therefore, the transfer of the book block from the preceding machine to the succeeding machine is carried out while accurately maintaining the mutual alignment of the loose sheets or signatures.

[Examples] Hereinafter, examples will be taken up and the present invention will be explained in more detail using the drawings.

In a collating machine as a front-stage machine, a carrying rod 2b hingedly attached to a circulating chain 2a, a book block mounting table 2C, and a groove-shaped guide conveyance path 2
A book block 1 consisting of loose paper sheets or signatures is interlocked from a collating machine at a certain period between a conveying system 2 consisting of d and an introduction device 3 of a non-overlocking bookbinding machine as a subsequent machine. A transfer system 4 is provided whose task is to transfer the books to the blank binding machine.

This delivery system includes a belt-type feeding device having belts 4a and 4b that are driven to circulate and move, and a book block mounting table 4C.

In order to receive the book block 1 trouble-free from the carrying companion 2b of the conveyor system 2 of the collating machine, the belts 4a and 4b of the transfer system 4 are driven at a higher speed compared to the conveyor system 2.

After being transferred from the conveying system 2 of the collating machine to the delivery system 4, the book block 1 is in an upright position with its back against the book block mounting table 4C, and is further conveyed by belts 4a and 4b.

The overlock binding machine semiconductor device 3 connected to the transfer system 4 is connected to a chain 5 which is driven in circular motion by a sprocket 5a of a drive shaft 15, hinged at a constant distance from each other, in a known manner. It has a plurality of carrying companions 6 which are attached in a formal manner.

As in the case of the conveyance system 2 in the collating machine, guide plates 8a and 8b, which are side members, are provided on the horizontal guide conveyance path assembled with the book block platform. Between this groove-shaped guide conveyance path and another book block platform, there is another groove-shaped guide conveyance path with guide plates 9a, 9b as side members, the guide plate 9a being a frame of the machine. The immovable side member, the guide plate 9b, connected to the guide plate 9b is formed as a movable side member so that the distance from the guide plate 9a can be changed.

In the inflow area of the introduction device 3 according to the invention, there are a book block holder 7 and a book block holder 3 in the previous stage.
A roller conveyor lO, which is a feeding device that receives the upright book blocks 1 from the delivery system 4, is provided between the

The roller 10a is rotatably supported by a side member 9a and a side member 11 fixed to the frame of the machine at a distance from the side member 9a.

The individual rows of the roller conveyor 10 are frictionally driven by a circulating belt 12. For this purpose, there are pressure rollers 13 rotatably supported on the side member 11, each of which is located in an area between two adjacent rollers and applies a force to the drive shaft portion of the roller 10a. Belt +2 is pressed so that it extends. The belt 12 circulates around a belt pulley 14 driven by a drive shaft 15 of the introduction device 3 and a roller 10a located at the front when viewed in the running direction of the roller conveyor 10.

The side members 9a extend upwardly from the roller conveyor 10 and, together with a guide plate 9b spaced apart from it, form a groove-shaped guide conveyance path for the book blocks l. The guide plate 9b is provided with a through hole 16 through which the roller 10a passes without a gap. This creates a groove-shaped guiding path with no lateral relief, which ensures trouble-free transport of book blocks consisting of loose sheets or signatures.

In the roller conveyor 10 according to the present invention in a non-overlocking bookbinding machine semiconductor device, the book block discharged from the delivery system 4 continues to move at a constant speed, whereupon the carrying partner 6 of the introducing device catches up, and this serves as the subsequent conveyor. transfer of the book block from the collating machine to the overlock binding machine while maintaining the exact alignment of the loose leaves or signatures of the book block with each other since the book block is handled without roughness. 6 will be sent.
