Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying conveyance device for promoting cooling and solidification of cover spine glue after cover pasting in bookbinding processes such as flat binding and perfect binding.

Conventionally, heat-melting adhesives such as hot-melt adhesives are used as adhesives for binding covers. , it is quite long and requires open dry time, and if three-sided cutting is performed before that time, problems such as deformation of the spine will occur. Therefore, in order to shorten the opening time, we either use a fan to blow wind on the back of the book or force the book through a cooling device to shorten the drying time. The current situation is to lengthen the subsequent conveyor to allow curing over time.

The present invention improves these points, reduces the space of the storage room as much as possible, and makes effective use of the space.Furthermore, the book storage system uses outside cold air in the winter and cold air from the air conditioner in the summer. The purpose is to accelerate the drying of the cover spine adhesive by both aging drying and forced drying.

The first aspect of the present invention is to provide a conveyor (1) horizontally on the floor surface (13) in FIG. stand (6

A phototube detector (5) is attached to the upper surface of the tip movement trajectory, and detects whether the book (18) being transferred is reliably transferred to a predetermined position on the upper surface of the conveyor table (6). For example, if the book (I8) is incorrectly positioned on the upper surface of the transport table (6) of the loading entrance (A), with the book (I8) positioned outside the opening of the loading entrance (1111), the phototube detector (5) will detect this. is detected, the next operation of the intermittent operation is stopped, and the main body of the device is stopped. Therefore, place the book (18) at the desired position on the top surface of the conveyor table (6).
After setting and correcting by hand, the first operation is started by pressing the operation reset switch on the main body of the device.

Books +181 are transported to the upper floor surface (14) by the transport table (6) of the vertical transport conveyor (2), and are pushed by the pushing plate (8) that moves horizontally by the air cylinder (4). It is pushed out from the exit (B) and transferred to the unloading conveyor (
) and transported. The pushing plate (8) is vertically attached to the tip of the shaft (9) of the air cylinder (4), and consists of a plurality of conveyance tables (6) attached to support bars attached to the shaft (91). (6) is approximately the same horizontal plane as the horizontal plane of the transport conveyor (1) and the transport conveyor (3) at the entrance (A) and exit (B) so as not to interfere with the transport of the book (18). The transport conveyor (II is the sprocket) (23
) and (24), and consists of opening/closing feed pawls (29) arranged at equal intervals.
It is placed on the slide plate (27), and then transferred to the unloading conveyor (3).
1 Cheno (opening/closing feed claws with several equally spaced opening/closing claws (held by two members) are pushed backwards and carried out.

Once dried, the adhesive on the back of the cover is forced to cool down after the cover has been pasted, and the adhesive on the back of the cover is safely transferred to the horizontal conveyor. 11) and the unloading conveyor (3) intermittently rotate endlessly at the same timing, and each time the conveyors (1) and (3) convey one pitch and stop, the vertical conveyor (2) rotates one pitch vertically. It moves in the direction and stops.
Immediately move the pushing plate (8) to 1 with the air cylinder (4).
After the cycle operation, the conveyors (1) and (3) perform the following operation.

To explain the second invention in more detail with reference to FIG. 2, the finished book (181), which has been pasted with a bookbinding cover after applying the Holatomeroot adhesive, is transported to the three-sided cutting process by a horizontal transport conveyor. The books (18) are stacked in an aligned manner in units of several books.The conveyor (1) conveys the books (18) while operating intermittently in synchronization with the respective conveyors at the rear.

The book (181) passes through the entrance (A) and is transferred to the top of the carriage (6) of the vertical conveyor 12 in Fig. 12.

The endless chino (20) is equipped with a plurality of transport tables (6) at equal intervals, and the books (181) to be transferred onto the transport table (6) are
are conveyed one after another vertically upward to the ceiling below the upper floor side.

Similarly to the first invention, on the side surface on the tip movement trajectory of the conveyor table (6) at the entrance (A) which is the starting point of the vertical conveyor (2),
Book 08) with phototube detector (5) attached and transported
It is detected whether or not it has been reliably transported to a predetermined position. For example, if the book (181) is incorrectly positioned outside the loading port (fA on the upper surface of the transport platform (6)), the phototube (5) will detect the deviation. The next periodic operation of the intermittent operation is stopped and the main body of the apparatus is stopped.

After manually setting the book (181) in the correct position on the top surface of the conveyor table (61), press the operation reset switch on the main body of the device to start the conveyance operation again. 6) to the lower ceiling of the upper floor (I4) (181 is the air cylinder (4)
