Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine that binds a predetermined number of stacked books bound by a bookbinding machine, attaches a backing paper, and ties them together in a criss-cross shape with a string.

This type of technique is known as described in Japanese Patent Application Laid-Open No. 55-5307, but this is not efficient because the vertical and horizontal straps are tied in sequence at different locations. The equipment is large.

The present invention solves the above-mentioned problem, and its purpose is to provide a device that can efficiently bind vertical and horizontal cords at the same place when binding a bundle of books with a padding paper. .

Therefore, in the present invention, paper sheets are applied diagonally to the top and bottom of the book bundle A on the transfer path in which a predetermined number of books are stacked, and the corresponding paper is guided upward and downward of the book bundle by the rotation guiding rod 11, and vertically by the string binding mechanism 40. In a book bundle binding machine with a patch paper, which wraps a string 34 and a horizontal string 43 around a book bundle together with a patch paper,
The book bundle A with the paper cover is transferred onto the roller 42 of the transfer path, a chain 36 is stretched between the sprockets provided on the upper and lower sides of the roller 42, and a vertical string is attached to the arm 37 attached to the chain 36. 34, and as the book bundle A moves onto the roller 42 and the sprocket rotates, the vertical string 34
is wrapped around the outer periphery of the bundle A along the transfer direction to perform vertical binding.On the other hand, four sprockets (a chain 45 is stretched around the roller 42) and This book bundle binding machine with a backing paper is characterized in that a horizontal cord 43 is hooked to an attached arm 46 and a chain 45 is rotated to bind the book bundle A in the lateral direction.

Next, a specific example of the binding machine according to the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a conveyor that rapidly transports the stacked book bundles A. A presser belt 2 is provided above, and a conveyor 3 is installed continuously with the conveyor 1, and a conveyor 4 is connected directly above the presser belt 2. When books are fed in between, l sheets of backing paper 5 are pulled out and transferred to the next conveyors 6 and 7.
While moving between books, place paper on the top and bottom of the book in a diagonal direction (commonly known as G).
It is called Kintaro Kake.

), and between the conveyors 3 and 6 and between the conveyors 4 and 7, feeding mechanisms 8 and 8' for the backing paper 5 are provided as detailed in FIGS. 5 and 6.

These cover paper supply mechanisms 8, 8' include suction tubes 10, 10' and paper guide rods 11, 11 that suck the top and bottom sheets of the cover paper support frames 9, 9' stacked below and above. The cover paper accommodated in the upper support frame 9' is always in contact with the group of receiving rollers 12 due to its own weight, and increases as it becomes lighter.

Further, the padding paper stored in the lower support frame 9 is supported by the pantograph mechanism 13 shown in FIG. When the paper is in contact with the switch actuation piece 15', and the paper does not reach a certain level C, the actuation piece 1
5' reverses the motor 16 to lower the pantograph mechanism 13 and replenish paper.

The pantograph mechanism 13 is connected to the motor shaft 1 as shown in FIG.
a female threaded arm 19 screwed into a threaded rod 18 connected to
The two-pronged actuating piece 22 that engages with the center shaft 21 of the rod 20 is pivoted by the fulcrum shaft 23, and the threaded rod 18 is rotated by the motor 16, so that the X rod 20 of the pantograph mechanism 13 is rotated as shown by the chain line. It is opened and the raised plate 14 is gradually raised.

Also, the motor 16 rotates in the opposite direction to lower the paper. It is meant to replenish.

Next, the suction tube 10.10' with the air suction ports 24, 24' of the paper supply mechanism 8, 8' is supported at both ends by the arms 26, 26'G with the shaft 25.25' as the fulcrum, and the air suction tube 10. mouth 24,2
4' are facing each other with 5 liters of backing paper, and arms 26 and 26' are the 5th
As shown by the chain line in the figure, when it comes into contact with the padding paper, it adsorbs a sheet of padding paper by the suction effect of the air sucked in from the suction port, and then descends again to attract a part of the padding paper.

Its operation is carried out by actuating arms 32, 32' shown in FIG. 1 which communicate with the cylinder 30, 30' and its piston rods 31, 31' and are pivotally mounted on the shaft 25, 25'.

Next, the guide rods 11, 11' rotating around the suction pipes 10, 10' are connected by a motor 27 and a gear transmission mechanism 28, and an eccentric ring 29 (attached to Therefore, as shown by the arrow in Fig. 6, the guide rod 11,
11' rotates and applies the suctioned paper to the upper and lower corners of the bundle of books between conveyors 3 and 4.

The 11 book bundles are sent between the next conveyors 6 and 7, so that the paper is positioned diagonally above and below the book bundles, and is further transferred to the conveyors 33 and 33' beyond that, in the longitudinal direction, that is, vertically. Do unity.

(See Figures 8 and 9) Conveyor 4.7.33'
is adjustable up and down.

In the vertical binding mechanism, a vertical string 34 pulled out from a case 35 is hooked to the tip of an arm 37 attached between upper and lower chains 36, 36' for each pair, and the book bundle A is moved forward and the sprockets holding the chains 36, 36' are connected. 38. Chain 3 with the rotation of 39
The arm 37 between the two rotations of 6 and 36' (arrow in Figure 8)
The vertical cords 34 move to surround the book bundle in the longitudinal direction and bind the cords at the button 41 of the vertical binding mechanism 40, completing the vertical binding.

Also, at this position, the book bundle A leaves the conveyor 33, 33' and is placed on several receiving rollers 42, 42', and at this position, the book bundle A is vertically bound as described above. It is a horizontal binding.

The lateral binding is performed at this position using the lateral straps 43.

The horizontal strings 43 are pulled out from the horizontal binding unit 44 and are inserted through the tips of the arms 46 between each pair of chains 45, 45', and each set of three three-row chains 45 is stretched over four sprockets 63. , 45', 45'', the entire lateral circumference of the book bundle A is bound at the button 41' as shown in the ninth figure.

In the figure, 47 and 47' are air nozzles that are pressed inward to prevent the edges of the paper from turning over during vertical binding, and 48 is a motor that operates the conveyors 6 and 7, which is operated via a belt transmission mechanism 49. .

A motor 50 operates the conveyors 33 and 33' via a belt transmission mechanism 51.

52.53 is the tension roller of the belt transmission mechanism 49.51, 54 is the operating motor of the longitudinal binding chain 36, 36', and the transmission mechanism 55. 56 to contact you.

57 is a support frame for the group of receiving rollers 42; 58 is a handle for adjusting the guide frame 59 to the right in the flow direction according to the width of the book; 58' is a handle for adjusting the guide frame 59 back and forth; 60 is a lateral binding The operating motors of the chains 45, 45' are connected via a transmission mechanism 61.

Reference numeral 62 indicates a string insertion ring for the arm 46, and reference numeral 64 indicates a string insertion ring fixed to the support frame 57.

Furthermore, in FIG. 2, 428 of the roller group 42 is free;
42b, 42c, and 42d are driven, and 42c in particular is driven after the horizontal binding is completed.

Further, in FIG. 3, 65 is a drive mechanism. According to the present invention, the backing paper can be reliably placed in the correct position without shifting or turning over, and the string can be tied in the correct position (crossing over the strings). Vertical and horizontal binding can be carried out at the same time in the same location, so the work is done smoothly, quickly and accurately. It also has the effect of providing efficient products.
