BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter mounting machine for connecting a cigarette and a filter at a winding portion, and more particularly to supplying tip paper used for the connection toward the winding portion. The present invention relates to a tip paper feeder for a filter mounting machine.

[0002]

2. Description of the Related Art In recent years, cigarettes having a light taste have been desired, and therefore cigarettes are usually equipped with a filter at one end thereof. What are these cigarettes and filters?
They are connected to each other by winding a piece of chip paper glued on them, and the filter is connected to the cigarette by a filter attachment device, a so-called filter attachment.

This filter attachment has a wrapping portion for a tip paper piece. The wrapping portion includes two cigarettes having a filter plug in the center thereof, and a glued tip paper piece. Are being supplied respectively. At the wrapping portion, two cigarettes and a filter plug are wrapped around the tip paper piece to make a connection between them. After that, two cigarettes with a filter connected by the tip paper piece are Cut from the center of the filter plug into individual filter cigarettes.

On the other hand, the device for supplying the tip paper piece toward the winding section is provided with a conveying path for guiding the tip paper fed from the roll toward the winding section, and this conveying path has an upstream side. The gluing device and the cutting device are sequentially arranged from the side. The gluing device transfers the gluing to one side of the chip paper to perform the gluing. On the other hand, the cutting device cuts the glued chip paper into predetermined lengths and After the paper piece is formed, the tip paper piece is supplied toward the winding portion.

Further, the chip paper supply device is provided with a heating device at a portion of the transport path located upstream of the gluing device, and the heating device is provided with this chip before gluing the chip paper. It heats the glued surface of the paper. When the tip paper is heated before being glued in this way, the glue applied to the tip paper piece is then dried by receiving heat from the tip paper, so when the tip paper piece is wrapped, The adhesive can be prevented from protruding from the chip paper piece, and the initial adhesive force of the adhesive can be increased, so that the chip paper piece can be stably wound. If the glue is not pre-dried effectively, the tip paper pieces will not be wound properly, causing air leaks, and the glue that has squeezed out will cause glue stains, resulting in a poor product appearance. Will be done.

[0006]

By the way, the above-mentioned heating device is constructed, for example, by embedding a heater in a roller that defines a conveying path, and this roller directly heats the glue of the chip paper. However, since the tipping paper before gluing is heated, it is difficult to properly heat the tipping paper. For example, if the tip paper is not sufficiently heated, the tip paper will cool before gluing, and the glue will not be sufficiently pre-dried after that, and conversely, if the rollers heat the tip paper excessively. In addition, there is a problem in that it is difficult to control the heating temperature of the roller and the pre-drying of the glue cannot be effectively performed, for example, the chip paper is warped to easily cause winding failure.

On the other hand, it is possible to arrange a heating roller with a heater on the downstream side of the gluing device. In this case,
This heating roller heats and dries the paste from the surface on the side opposite to the gluing surface via the chip paper, and in this case also, the heat and drying of the glue cannot be performed directly, and an effective glue Can't expect pre-drying. The present invention has been made based on the above-mentioned circumstances, and an object thereof is to provide a tip paper supply device for a filter mounting machine capable of effectively and reliably pre-drying the paste applied to the tip paper. To provide.

And a hot air heater for directly blowing hot air.

[0009]

Operation: When the tipping paper fed from the roll is guided along its conveying path and passes through the gluing device, the glue is applied to one surface of the tipping paper, and then the glued tipping paper is heated with warm air. When passing through the heater, the warm air from the warm air heater is directly blown onto the gluing surface of the chip paper to pre-dry the glue. After passing through the cutting device, the chip paper with glue that has been subjected to the pre-drying process is cut into chip paper pieces by a predetermined length and supplied toward the winding part of the filter mounting machine.

The two filter cigarettes connected by the tip paper pieces are then cut from the center of the filter plug in the process of being conveyed on the grooved drums of the drum row 38 having the known structure. , Cigarettes with filters having filter chips individually, and the individual cigarettes with filters are transferred to the conveyor after their orientations are aligned, and from this conveyor, toward the packaging machine in the subsequent stage. Has been supplied. The flow of this processing is shown in the area P5 in FIG. 2, and FC indicates a fill chip.

Since the above-mentioned tip paper P supply device is provided with the warm air heater 16 on the downstream side of the gluing device 12 and on the upstream side of the cutting device 34, the warm air heater 16 is provided.
The gluing surface of the tip paper P can be directly heated by the hot air blown from. Therefore, the pre-drying of the glue can be effectively and surely performed, and thereafter, when the tip paper piece obtained by cutting the tip paper is wrapped around the cigarette and the filter plug, the glue protrudes from the tip paper piece. There is no such thing. Also, since the glue can be pre-dried reliably, its initial adhesive strength is further increased,
It is possible to prevent defective winding of the tip paper piece and manufacture a cigarette with a filter of excellent quality.

Further, if the paste is pre-dried with warm air,
Since the temperature and volume of the warm air can be easily adjusted,
Even if the glue or the tip paper material is changed, the change can be dealt with promptly, and even if the tip paper is slightly meandered, the paste surface can be made uniform. There is also an advantage that various pre-drying is possible. In the above-described embodiment, the preheater is arranged on the upstream side of the gluing device. However, this preheater is not always necessary, and there is a situation in which the predrying of the glue can be sufficiently performed only by the warm air heater. However, various modifications can be made in implementing the present invention, such as omitting the preheater.

[0027]

As described above, according to the feeding device of the present invention, after gluing on one surface of the chip paper, the hot air from the warm air heater is directly blown to this gluing surface. The paste can be pre-dried effectively and reliably. As a result, when the tip paper piece obtained by cutting the tip paper is wrapped around a cigarette or a filter plug, the glue does not stick out from the tip paper piece and damage the appearance, and the initial adhesive strength of the glue increases. Therefore, it is possible to prevent the winding failure of the tipping paper piece and to exert an excellent effect.
