BACKGROUND OF THE INVENTION
The present invention relates to a fluorescent lamp film cutting device for cutting a film coated on a used fluorescent lamp.
[0002]
[Prior art]
In recent years, the amount of waste has been increasing. However, landfills for reclaiming the waste are becoming tight and new sites are difficult. Therefore, in order to build a resource recycling society, the amount of waste generated is reduced and the recycling of waste is promoted. Against this background, fluorescent lamps that have been used and discarded have not been landfilled as in the past, but have been reused as resources. Used fluorescent lamps discharged from ordinary homes and offices are collected separately and temporarily stored. When a predetermined amount of used fluorescent lamps are collected, they are transported to a recycling facility and recycled as new resources. The problem here is the storage and transportation of collected used fluorescent lamps. When a used fluorescent lamp is stored and transported in the shape of a product (in an unbroken state), the volume increases, resulting in uneconomical storage efficiency and transport efficiency. Therefore, the collected used fluorescent lamps are subjected to volume reduction processing to reduce the volume by rough crushing. As a crushing apparatus that performs this volume reduction treatment, for example, there is one described in Patent Document 1.

[Problems to be solved by the invention]
By the way, the used fluorescent lamp which is a process target object has a thing with a scattering prevention film. This fluorescent lamp with anti-scattering coating is a film-like coating made of a synthetic resin such as polyester or polyethylene terephthalate to prevent the glass piece from scattering when the glass tube is broken. The whole is covered. As a use application, it is widely used in lighting devices that are not provided with a cover, particularly in facilities where many people gather or in trains.
When the coated fluorescent lamp is crushed by a crushing device, the coating is mixed with the crushed glass pieces and the like, which causes a problem that the recycling efficiency is lowered.
[0005]
Therefore, before the volume reduction treatment by the crushing apparatus, it is necessary to perform an operation of cutting and peeling the coating from the coated fluorescent lamp as a pretreatment. Since this operation is performed manually by an operator using a commercially available cutter knife or the like, it is difficult to cut the film at once in the longitudinal direction of the fluorescent lamp, and it has been necessary to divide and cut. For this reason, uncut portions that are not cut in the film are likely to remain, and may not be peeled off successfully. Thus, the operation | work which cut | disconnects the film in pre-processing was very difficult, and the effort and time were required.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fluorescent lamp film cutting device capable of easily and reliably cutting a fluorescent lamp film.
[0006]
[Means for Solving the Problems]
The present invention provides a cylindrical body capable of inserting a fluorescent lamp whose outer peripheral surface is coated with a coating film in the longitudinal direction, and a cutting blade provided on the cylindrical body and capable of cutting the coating film of the fluorescent lamp inserted through the cylindrical body. It is characterized by having.
According to the present invention, the fluorescent lamp coating can be easily and reliably cut by inserting the fluorescent lamp into the cylindrical body.
[0007]
Moreover, it is preferable to provide the elastic body which urges | biases the said cutting blade to the radial direction inner side of the said cylinder. In this case, since the cutting blade is urged toward the radially inner side of the cylindrical body, the cutting blade can be made to follow the shape of the fluorescent lamp further. Therefore, it is possible to reliably cut the film of the inserted fluorescent lamp.
[0008]
Moreover, it is preferable that the said cutting blade is a disk shaped rotary blade which cut | disconnects the film of a fluorescent lamp with rotation. In this case, since the coating is cut with rotation, the specific portion of the rotary blade does not always come into contact with the coating and cut. Therefore, the life of the cutting blade can be extended.
[0009]
Moreover, it is preferable that a plurality of the cutting blades are arranged in the circumferential direction of the cylindrical body. In this case, since the fluorescent lamp coating is cut at a plurality of locations in the circumferential direction, the coating can be more reliably cut and more easily peeled off.
[0010]
The cutting blade is provided at a plurality of locations in the circumferential direction of the cylindrical body, and the fluorescent lamp to be inserted is provided by the plurality of cutting blades, or by the plurality of cutting blades and the inner peripheral surface of the cylindrical body. It is preferable that they are arranged so as to be supported at least at three points. In this case, the fluorescent lamp inserted through the cylindrical body is supported at least at three points by the cutting blades arranged at a plurality of locations, or by the cutting blade and the inner peripheral surface of the cylindrical body. It is possible to prevent the fluorescent lamp from shaking when the fluorescent lamp is inserted into the lamp.
