However, the former stirring method cannot completely remove bad odors and is ineffective in improving the working environment.

In addition, the latter forced deodorization method has a structure in which the bad odor absorbed by the exhaust fan is guided to the activated carbon part through pipes or ducts, so the overall structure is complex, the assembly cost is high, and the resistance to airflow is large, making it inefficient. Additionally, there is a problem in that work such as repairing the exhaust fan and replacing activated carbon is troublesome.

This idea was made to solve the above problems, and the purpose was to provide a deodorizing device with low suction resistance, excellent forced deodorizing efficiency, simple structure, and easy assembly and disassembly. be.

[Means for solving problems]

In order to solve the above problems, this invention consists of a container that stores the deodorizer and an exhaust fan that is prepared separately from this container. It has a suction port and a discharge port on the lower surface of the other end, and is formed by storing a deodorizer between the suction port and the discharge port inside, and the suction port faces the welding part of the packaging machine, and the open top surface is removably fixed to the inner surface of the top lid so that it is closed by the top lid, and the exhaust fan is
The structure is such that the suction port is fixed to the table directly below the discharge port of the container so that the suction port overlaps and communicates with the discharge port without being combined with the discharge port.

[Effect]

An exhaust fan is connected to the outlet of the container, which is arranged so that the inlet faces the welded part of the packaging machine, and when the exhaust fan is started, the bad odor generated at the welded part is sucked into the container through the inlet, and the deodorizer is removed. Upon contact, malodorous components are adsorbed and removed by the deodorizer, and the deodorized air is discharged to the outside through the exhaust fan.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, a table 1 has an upper lid 2 stretched over its upper surface, and various members and equipment constituting a packaging machine are housed inside the table 1.

It consists of a tape feeding and tightening mechanism that feeds and tightens the tape from the tape passage 3 onto the top lid 2, and a motor and cam mechanism that operate these mechanisms.

The packing work is carried out by placing the item on the top lid 2 of the table 1, wrapping the tape around the outer circumference of the item, and inserting the tip into the bottom surface of the base.The first clamp clamps the tape insertion side, and the tape is tightened. Binding of the item, simultaneous clamping of the upper and lower tapes by the second clamp, cutting of the lower tape by raising the pressurizer, entry of the heater 4 between the upper and lower tapes, melting of the opposing surfaces of the upper and lower tapes by pressing with the pressurizer, and removal of the heater. The process is completed by welding with a pressurizer after the process is completed, and the lateral movement of the base after both clamps and the pressurizer are lowered, and the tape A is fed out a predetermined length onto the top cover 2 by the feeding and tightening mechanism in preparation for the next packing. It is something.

In the packaging machine, the deodorizing device for removing the bad odor generated when the tape is heated and melted by the heater 4 includes a container 11 attached to the inner surface of the upper lid 2 and a deodorizer stored in the container 11 in the table 1. 12 and an exhaust fan 13 placed at the bottom of the container 11
It is made up of.

The container 11 is formed in a rectangular box shape with an open top, and is removably attached to the inner surface of the top lid 2 by means such as screws, and the top opening is closed by the top lid 2.
As shown in the figure, the suction port 14 provided at one end of the peripheral wall
It is arranged so as to be close to the heater 4.

A wire mesh 15 is provided at a predetermined distance inside the container 11.
A deodorizer 12 using activated carbon or the like is stored between both wire meshes 15. On both sides sandwiching the deodorizer 12, there is a front chamber 16 communicating with the suction port 14, and a rear chamber 17 at the rear. A discharge port 18 communicating with the rear chamber 17 is provided in the bottom wall of the container 11.

The exhaust fan 13 has blades built into a body 19 having a suction port on the top surface and an air outlet on the outer periphery, and has a structure in which the blades are driven by a motor 20, and is fixed on a mounting base 21 within the table 1. , the suction port on the top surface communicates with the discharge port 18 of the container 11.
