Was transported.
[0003]
[Problems to be solved by the invention]
By the way, when performing this high-speed tact operation, the book in the book storage compartment may be collapsed by inertia due to its intermittent operation, and the book storage compartment may be formed as a means for preventing this. Since the inside size between the two partition plates is set to be approximately the same as the size of the book to be conveyed, only books having a certain width can be conveyed. However, in order to transport books of various sizes, using external actuation means so that the inner dimensions of the partition plate can be changed according to the size of the book will complicate the structure, and some devices will be installed on the slats. Since it is to be mounted, the electric motor for operating the chain conveyor requires a large capacity, and there is a drawback that the chain size of the chain conveyor increases.
Therefore, the present invention has been made in view of the above-mentioned problems of the prior art, and has been made to solve the problem. The inner size of the partition plate can be easily adjusted to the size of the book so that books of various sizes can be transported. A simple and easy-to-operate structure capable of reliably transporting books being transported by high-speed tact operation without causing collapse of the load and obtaining a robust transporting device in a robust automatic shipping line at low cost It is intended for.

[0006]
With this configuration, in order to transport the book A by the book transport conveyor body 1, the two partition plates 41 and the partition plates 51 constituting the book storage section 6 according to the size of the book A to be transported are provided. Adjust the spacing of For example, when a small book A is to be conveyed, the servomotor 27 is driven to rotate the driving shaft 23 via the toothed pulley 25 and the toothed belt 26, and the partition plate 41 attached to the chain 21 of the outer chain conveyor 2. 3 is moved to the right in FIG. 3, while the servomotor 37 is driven to rotate the driving shaft 33 via the toothed pulley 35 and the toothed belt 36 to thereby separate the partition plate 51 attached to the chain 31 of the inner chain conveyor 3. Move to the left. As a result, the distance between the partition plates 41 and the partition plates 51 approaches each other, and can be adjusted to match the size of the book A that conveys the inner dimensions of the book storage section 6. At this time, at the same time, the mounting plate 42 and the inner receiving roller 45 are attached to the mounting plate 52 and the inner receiving roller 55 facing each other so as to be staggered from each other. Be placed. Further, the rear portion of the book transporting conveyor body 1 is adjusted to correspond to the size of the book to be stored by operating the air cylinder 64 to move the back plate 63 back and forth.
When the inner size of the book storage section 6 is adjusted to a desired position as described above, the two servomotors 27 and 37 are driven to rotate in the same direction. Since this rotation is performed in a tact operation synchronized with each other at a tact pitch interval, both rotations of the two servo motors 27 and 37 are received via the toothed pulleys 25 and 35 and the toothed belts 26 and 36, respectively. The shafts 23 and 33 are rotationally driven, whereby the chain 21 of the outer chain conveyor 2 and the chain 31 of the inner chain conveyor 3 intermittently rotate in the same direction at a constant speed. Therefore, the book A is cut out to the book storage section 6 from each of the book cutting devices 71 installed along the book transporting conveyor body 1, and the book A is intermittently driven by the synchronous tact operation of the outer chain conveyor 2 and the inner chain conveyor 3. And discharged from the discharge table 72. At this time, since both the chain conveyors 2 and 3 use servo motors, the operation speed and the acceleration / deceleration time at the time of stop can be easily and easily controlled, and both the partition plates 41 and 51 follow this operation and the The dimensions are reliably maintained and move, and a high-speed tact operation of 400 mm / s is possible while maintaining the package.
Furthermore, when the book A to be transported is large, the operation reverse to the above operation is performed to increase the distance between the two partition plates 41 and the partition plate 51 constituting the inner dimensions of the book storage section 6 and to transport the book A. Adjust it to fit the size. Thereafter, the two servo motors 27 and 37 are driven to rotate in the same direction to perform a synchronous tact operation in which the chain 21 of the outer chain conveyor 2 and the chain 31 of the inner chain conveyor 3 rotate intermittently at the same speed in the same direction. The book A can be transported intermittently.
[0007]
As means for adjusting the interval between the two partition plates constituting the book storage section of the above embodiment, the outer chain conveyor and the inner chain conveyor were rotated in opposite directions by both servomotors. Alternatively, the chain of one of the chain conveyors may be rotated by a servomotor and moved relatively to the chain of the other chain conveyor.
