[Operation] When a fixed amount of the objects to be bound are manually put into the hopper of the aligning mechanism in a vertical direction with the base side facing downward, a constant amount of the objects to be bound are oscillated by the vibration device through the hopper. A vibration is applied in the front-back direction to the roots of the fixed-quantity objects to be bound.

Then, the shutter at the lower end of the hopper is opened to drop the fixed quantity bound objects on the receiving tray, and the fixed quantity bound objects are realigned on the upper surface of the receiving tray even during this movement. Next, as the tray is lowered, the fixed quantity bound object is lowered and conveyed to the stop position of the telescopic arm in the conveying mechanism, and stopped at that position to stand by.

Next, the telescopic arm is rotated in a predetermined direction by a predetermined angle (90 °) by the rotor and stopped at a position facing the binding mechanism, whereby the fixed quantity binding object is vertically changed by 180 °. This means that the paper was rotated and conveyed in the facing state. Then, as the telescopic arm is extended, the fixed amount binding portion is inserted between the first and second rotating arms which are in the binding mechanism and are opened by rotating in the left-right direction in the vertical direction. It

Since the adhesive tape for binding is stretched in advance between the first and second rotating arms of the binding mechanism, the fixed amount of the object to be bound is pressed against the adhesive surface of the adhesive tape. As a result, the adhesive tape is wound around the outer peripheral surface of the rod-shaped fixed amount binding object and substantially half its circumference.

Then, the first and second rotating arms are closed by being rotated inward, respectively. At this time, the adhesive tape is attached by the pawl attached to the tip of the first rotating arm. On the other hand, the adhesive tape which is unwound from the reel and has been previously wound around the tape winding roller of the shaft support at the tip of the second rotation arm is pressed by the tape pulling roller of the shaft support at the tip of the same rotation arm. Since it is fed out by the
It will be delivered from both left and right sides.

Further, when both the first and second rotary arms are closed by rotation, the claws on the first rotary arm and
The tape pulling roller in the second rotating arm crosses each other inward and outward, and at this time, the tip end side and the base end side of the adhesive tape are adhered on their respective adhering surfaces. When the first and second rotating arms are closed by the rotation, the base end side of the adhesive tape is cut by a cutter attached to the tip of the first rotating arm, and the fixed quantity binding object is pasted with the adhesive tape. Are united in.

Then, when the telescopic arm extends and grips the fixed amount of the object to be bound, the telescopic arm is rotated by a rotor in a predetermined direction by a predetermined angle (90 °) to vertically orient the object to be bound. After being rotatably conveyed and stopped at a position facing the finishing mechanism, the telescopic arm is contracted, and the holding mechanism releases the fixed amount of the object to be bound. As a result, the fixed amount of objects to be bound are horizontally fed onto the inclined guide plate of the finishing mechanism, and at the same time, they roll in the circumferential direction and are sandwiched between the guide plate and the conveyor belt to convey the object. The belt is rotated and conveyed in the same direction while being rotated and conveyed downward.

When the fixed quantity of the object to be bound is conveyed part way, the end length of the adhesive tape for binding the fixed quantity of the object to be bound is attached to the hanging piece which is a goodwill hanging above the guide plate. Although the non-adhesive surface of the portion is pressed, the fixed amount of the object to be bound is conveyed while being forcibly rotated in the circumferential direction by the conveyor belt, so that the terminal long portion is laid down by the hanging piece. Then, the adhesive surface is attached together with the terminal short portion along the outer peripheral surface of the binding portion by the adhesive tape. As a result, the terminal long portion and the terminal short portion of the adhesive tape are wound around the outer peripheral surface of the adhesive tape and finished so as not to project outward.

The fixed amount of the bundle to be bound in this manner is supplied from the lower end of the guide plate onto the lower carry-out conveyor, and is conveyed to a predetermined position by the carry-out conveyor.

Since the present invention is constructed as described above, the direction in which the objects to be bound are conveyed is the vertical direction due to the rotation of the conveying mechanism, so that the lateral width can be made particularly narrow and the size can be reduced. At the same time, the fixed amount of objects to be bound are aligned at the end face on the root side by the aligning mechanism, gripped by the transport mechanism, and sequentially transported to the binding mechanism and the finishing mechanism by rotation, so that they are tidy and have a good appearance. Bundling can be performed efficiently in a small space.

Further, since the adhesive tape of the binding mechanism is of the cassette type, the adhesive tape can be replaced quickly, and the down time of the binding machine at the time of the adhesive tape exchange can be shortened. It can be further improved.
