Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an automatic binding device that ties together books by stringing them together, and in particular, the invention relates to an automatic binding device for binding books, etc., by stringing them together. It is suitable for being transported by conveyor and automatically bound.

(Prior Art) Conventionally, a stack of books is sequentially transferred to a predetermined position by a conveyor, and then held by an operator's hands and bound using a stringing and binding machine. As this binding machine, for example, the one shown in FIG. 4 is used. In this figure, 110 is a string that is rotatably supported by a support part 112 provided on a binding machine body 111 and rotated a predetermined number of times by an electric motor (not shown) by operating a switch such as a foot switch (not shown). The hanging arm holds a string 113 supplied from the center of the rear shaft and winds the string around articles to be bound (not shown).
115 is a fixed table fixed to the binding machine main body 111, and 116 is a movable table arranged with a gap 117 between the fixed table and the string 113 through which the string 113 can pass, and supported so as to be rotatable about the same axis as the stringing arm 110. The articles to be bundled are supported by a fixed table 115 and a movable table 116. 118 is a knotting and cutting mechanism that connects the string 113
The stringing arm 110 rotates a predetermined number of times to wrap the string 113 around the articles to be bound, then tie and cut the string. Such a tying machine has the disadvantage that it requires a lot of labor and time from the operator. Therefore, in order to solve this problem, there is a proposal as disclosed in Japanese Patent Laid-Open No. 5307-1983. This device automatically feeds the items to be bound from the front of the binding machine and performs the first binding, and then moves the items to the front of the next binding machine to perform the second binding. It is configured. With such devices, it is not possible to use commercially available binding machines, it is completely unclear how the part corresponding to the movable table is constructed, and the structure of the part that moves the objects to be bound is complicated. The disadvantage is that it becomes expensive. A binding device that automatically feeds and bundles items from the side using a commercially available binding machine and then sends them out in the same direction has a simple structure and is convenient for processing after binding. However, because the movable table tilted, it was not put into practical use.

(Problems to be solved by this invention) This invention solves these problems by using a generally commercially available binding machine to feed the objects from the side, bundle them, and move them in the same direction. To provide an automatic bundling device which has a simple structure and is convenient for processing bound objects.

(Means for Solving the Problems) This device is designed to bind objects using a string, and has a string arm that rotates to wrap the string around the object to be bound. A binding machine equipped with a table rotatably supported around a rotational axis to support one side of the object to be bound, wherein the binding machine is provided with a table that is rotatably supported around a rotational axis and has a table for supporting one side of the object to be bound. A supporting member arranged to support the other side of the object to be bound; an engaging member releasably engaging an engaging portion provided on the table beyond a portion through which the string passes from the supporting member; and this engaging member. an operating means configured to move the object forward to engage the engaging portion and to release the engagement by moving it backward at least during tying, and a tying position in which the objects to be tied are supported by the table and the support member; The present invention provides an automatic bundling device characterized in that it includes a transport means for feeding the paper into the bundling position and sending it out from the bundling position after bundling.

(Example) An example of this invention will be described below with reference to the drawings.

In one embodiment of this invention shown in FIGS. 1 to 3, numeral 10 is a tying machine similar to conventional commercially available tying machines for tying with string, which rotates and wraps the lace around the object 90. String arm 1
1, and is provided with a table 12 similar to that shown as a movable table 116 in FIG. 4, which is rotatably mounted around the rotational axis of the lace arm as shown by the chain line in FIG. When tying, the string passes slightly outside the outer edge of the table. 13 is a guide member provided on this table 12.

Reference numeral 15 denotes a support member that is arranged at a fixed position with a slight gap between the end edge of the table 12 and the string so that it can pass, and forms a support surface that is flush with the surface of the table 12. 16 is this support member 15
This is an engaging member attached to the lower surface of the table so that it can move forward and backward.It is operated by an air cylinder 17 and engages with an annular engaging portion 18 provided at the bottom of the table 12 beyond the part through which the string passes, thereby causing the table to rotate. It is fixed so that it does not move, and when tied, it is set back from the part through which the string passes, allowing the string to pass through.

20 is a belt conveyor placed on the feeding side,
Objects 90 to be bound are sent by a conveyor (not shown) so that they are jointly supported on the table 12 and the support member 15. 21 is intermittently driven adjacent to this conveyor 20 and advances while pressing the rear end side of the objects 90 on the conveyor 20 with the pressing piece 22, so that even if separated from the conveyor 20, the objects 90 are kept on the table 12 and the support member 15. The conveyor has an upright endless track-shaped circumferential surface member 23 that moves to a predetermined binding position and stops as shown by the solid line in FIG. 1, and the pressing pieces 22 are provided at equal intervals. In response to a signal from the conveyor 21 that the objects 90 to be bound have come to the binding position, the engaging member 16 moves backward, and then the stringing arm 11 of the binding machine 10 operates to complete the binding. In response to this binding completion signal, the conveyor 21 is driven again, and the objects 90 to be bound are moved forward onto another belt conveyor 25 and delivered by this conveyor 25. Reference numeral 26 denotes a pressing member which presses and holds the objects 90 to be bound from above against the support member 15 when they have come to the binding position, and is operated by an air cylinder 27 and moves upward when the binding is completed. .

In the configuration as described above, the objects 90 to be bound are transferred to the conveyor 20, with the engagement member 16 engaged with the engagement portion 18 and the table 12 fixed.

0 is supported near the center of the rotatable table 12 by a fixed supporting member 15 and is pressed by a pressing member 26, so that the table 12 does not tilt. In response to a binding completion signal, the engaging member 16 engages with the engaging portion 18 again to fix the table 12, and after the pressing member 26 is raised, it is sent out by the conveyors 21, 25.
These operations are caused to generate signals by a computer such as a microcomputer (not shown).

In this invention, the object to be bound 90 is made of a stack of books, etc., and is held in front in a perpendicular direction to a binding part 91 formed by a binding machine 10, and a binding part 92 is formed by another binding machine (not shown). However, there are cases where such a binding portion 92 is not formed, and the object 90 to be bound may be other than a stack of books or the like. Further, the pressing member 26 may not be provided.

(Effect of the invention) As described above, in this invention, the table 12 of the binding machine 10 is fixed by the engaging member 16 releasably engaging with the engaging part 18, and the object to be bound 9
Since the wires can be fed in from the side of the binding machine 10 and sent out in the same direction after binding, an automatic binding device with a simple structure and convenient for processing the objects 90 to be bound can be obtained. It has this effect.
