Description

[Detailed description of the invention] [Industrial application field] The present invention is a method for forming the back of a core book into a round or square shape at the introduction and discharge parts of a top binding machine or an automatic reversing connecting device. The present invention relates to an improvement in a book transport device capable of supporting the edge portion and transporting the book block in an upright state.

[Prior art] Conventionally, various bookbinding operations have been performed in the process of manufacturing core bound books, and for this reason, single-handed binding machines such as rounded edges, spine pasting machines, cover wrapping machines, and single-forming machines have been used. Machines are used in various combinations and connected.
An automatic reversing coupling device is usually used between each of these individual machines, and the individual machines are coupled while suitably inverting the backs of the book blocks from upward to downward or from downward to upward.

The inlet and discharge parts of these individual machines or the inlet and discharge parts of the automatic reversing coupling device are equipped with a conveyor device in which a large number of flat belts made of rubber or convex or concave rollers made of metal, plastic, etc. are arranged in a solo band shape. are used for timing and buffering purposes to facilitate the transfer of book blocks between each machine.

[Problems to be solved by the invention] However, in the case of a conveying device in which a large number of the flat belts or convex or concave rollers are arranged in a solo band shape, the conveyance device simply conveys the book blocks.
There was a strong tendency to damage the back of the book, which had been painstakingly molded.

In other words, the book blocks whose backs have been formed into a round mountain shape or square mountain shape using a rounded edge extraction machine have not yet been solidified, so if they are lowered onto a flat belt with their backs facing upward at the discharge section of the 180-degree reversing coupling device, they will not be solidified. Since the flat belt does not have a radius, it does not fit the shape of the edge of the book.
Therefore, the shape of the spine easily collapses due to the weight of the book block itself.

Similar problems are also observed in the discharge section of the 180-degree reversal coupling device that connects the spine pasting machine and the cover wrapping machine, and the introduction section of the cover wrapping machine. Here, the opposite side of the back of the booklet, that is, the edge side having the half-moon-shaped recess, supports the weight of the booklet, so the transport device that receives it is usually a convex metal,
Rollers made of plastic or the like are used, but since a plurality of rollers are provided at predetermined intervals to support the book blocks, there is a problem that the supporting area for the book blocks is small.

In addition, in order to transport books smoothly, the distance between the rolls must be set so that three or more rolls can be received at the same time, even for the smallest size of book blocks, so the radius in the axial direction can only be large, and the rolls are in contact with the book blocks at several points. Since only the apex is formed, for thick books, the weight of the middle book deforms the book, resulting in a flattened rounded spine, which causes problems in subsequent processes. In addition, in the case of thin and light book blocks, the conveyance force by the rolls is overcome by the frictional force of the guide plates provided on both sides of the book blocks, making the conveyance unstable and causing frequent mechanical troubles. That is, the book blocks were stagnant due to the frictional force with the guide plates provided on both sides of the book blocks, and could not be fed smoothly. In the case of thick book blocks, the load concentrates on the part that is in contact with the rollers, making it impossible to avoid deformation of the back of that part.

For this reason, there has been a strong desire to develop a conveyance device that can smoothly transport the book blocks without deforming the shape of the back of the book blocks and without stagnating the book blocks in an upright position.

The present invention was made in response to the above-mentioned request, and is designed to be installed at the inlet and discharge parts of each individual bookbinding machine, or between these individual machines, for making the backs of core books in a round or square shape. The small end of the book is supported by the introduction and discharge parts of the automatic reversing coupling device, and the book is transported smoothly without stagnation in an upright state.
To provide a transport device for book blocks that can smoothly and stably transport the book blocks without damaging the backs of the book blocks.

Further, in the present invention, rollers having outer peripheries having an arcuate cross-section are provided on both sides of the conveying device, and a guide body having an arcuate cross-section similar to that of the rollers is installed above the inner side of these two rollers and is placed on the same level as the outer periphery. A flat belt is provided on the line and engages the roller and the guide body to increase the support area of the edge of the booklet, so that the booklet can be smoothly conveyed in an upright state without stagnation, and the back of the booklet can be conveyed smoothly. An object of the present invention is to provide a conveyance device for book blocks that can smoothly and stably convey books without damaging them.
