[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a can material discriminating tool used for discriminating iron cans and aluminum cans when separating empty cans.

[0002]

[Prior art]

 Cans for canning, especially cans for beer and cans for various types of juice, can be roughly divided into iron cans and aluminum cans, but since these empty cans are recyclable as resources, for example, PTA and municipalities in the housing complex Many activities are being conducted to collect the items collected from ordinary households or the items collected by children and sell them to a waste collection company, and use the profits as part of operating funds. The huge amount of cans that were put out at the collection site at the time of collecting these empty cans contained iron cans and aluminum cans, and because they were not picked up by the dealer as they were, they were separated into iron ones and aluminum ones. Must. Conventionally, the method of separating empty cans has been performed by holding a solid magnet in the shape of a horseshoe or a block and bringing it into contact with the can, and then distinguishing the can material by the presence or absence of its exciting action. However, if a child is allowed to help determine the contact of such a solid magnet to a can, it will be boring because it is monotonous and has no interest, while the outer surface of the can is an arc surface. In addition to that, if the magnet is held by hand, the magnet is directly moved by the force of the hand, so the feeling when attracting or separating the magnet is dull, and it is difficult to know the presence or absence of magnetic force. .

[0003]

[Problems to be solved by the device]

 The present invention is an attempt to improve it in view of the conventional situation as described above, and an object of the present invention is to make it possible for a child to make an interesting discrimination work without getting tired. The point is that the presence or absence of magnetic force can be identified more clearly, and the concrete means and action are as follows.

【Example】

 Specific embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 are drawings showing a first embodiment of the present invention, in which 1 shows a can material discriminating tool according to the present invention. Reference numeral 2 denotes a thin plate-shaped elastic body that constitutes the can material discriminating tool 1. The elastic body 2 is formed in a rectangular shape, and a magnet sheet 3 is fixed to one surface of the elastic body 2 while being biased to one end in the longitudinal direction. The magnet sheet 3 is provided so that magnetic powder is dispersed in a sheet of synthetic rubber or soft synthetic resin so that a permanent magnetic force is generated from the entire surface of the sheet 3.

FIG. 3 is a view showing a second embodiment. The thin plate elastic body 2 is formed in a rectangular shape as in the first embodiment, and the thin plate elastic body 2 has long sides on both front and back sides. The magnet sheets 3 and 3 are fixed to each other while being biased to one end in the direction.

FIG. 4 is a view showing a third embodiment. The thin plate-like elastic body 2 is formed in a rectangular shape as in the first embodiment, and one surface thereof is biased at both ends in the longitudinal direction. The magnet sheets 3 and 3 are fixed to each other so that the magnet sheets 3 and 3 are placed side by side. Further, although not shown, it is possible to fix the magnet sheets not only on one side but also on both front and back sides of both ends.

FIG. 5 is a view showing a fourth embodiment. This embodiment is a modification for better vibrating the thin plate elastic body 2 due to the elasticity, and is a thin plate elastic body 2. The magnet sheet 3 is fixedly biased to one end in the longitudinal direction, and a portion where the magnet sheet 3 is not fixed is formed to be narrower than a portion where the magnet sheet 3 is fixed.

FIG. 6 and FIG. 7 are drawings showing a fifth embodiment. As in the first embodiment, one side of the thin plate elastic body 2 formed in a rectangular shape is biased to one end in the longitudinal direction. The magnet sheet 3 is fixed so that the magnet sheet 3 is fixed. A through hole 4 is opened at approximately the center of the magnet sheet 3, and a large diameter portion 5 is formed by expanding the inner diameter portion of the through hole 4 on the thin plate elastic body 2 side. A magnifying lens 6 is housed in the section 5, while a window hole 7 is opened in the thin plate elastic body 2 at a position corresponding to the magnifying lens 6.

FIGS. 9 and 10 are views showing a sixth embodiment. The can material discriminating tool 1 is formed of a strip-shaped magnet sheet 3 having appropriate flexibility, and both end portions in the longitudinal direction thereof. A ring-shaped rubber band 8 extending to the back side is attached to this.

FIG. 11 is a view showing a seventh embodiment. The can material discriminating tool 1 comprises a glove 9 and a belt-shaped magnet sheet 3 having appropriate flexibility, and the magnet sheet 3 is a handbag. It is fixed to the palm part of 9. Instead of the magnet sheet 3, it is also possible to mix magnetic powder with an adhesive and apply it to the palm portion.

Next, the method of use and operation will be described. In the first and second embodiments and the fourth and fifth embodiments, as shown in FIG. 8, one end of the thin plate-like elastic body 2 on the side where the magnet sheet 3 is not fixed is finger-tipped. Then, if it is shaken lightly, an action of vibrating the thin plate elastic body 2 like a pendulum by its elasticity and the inertia of the magnet sheet 3 at the other end can be obtained. In addition, in the third embodiment, since the magnet sheets 3 are fixed to the left and right sides of the thin plate-like elastic body 2, whichever end is held by the finger is similar to the above. Vibration effect is obtained. Further, in the fourth embodiment, the thin plate-like elastic body 2 is formed with a narrow width in the portion to which the magnet sheet 3 is not fixed, so that the above-mentioned vibration action can be obtained more effectively. . When the magnet sheet 3 at the tip of the elastic body 2 is brought into contact with the empty can 10 as shown in FIG. If it is made of iron, it will not be attracted, but if it is made of iron, the magnet sheet 3 will be attracted to the empty can 10. At this time, since the thin plate-shaped elastic body 2 has an end portion that is separated from the magnet sheet 3, the central portion of the thin plate-shaped elastic body 2 is curved through its elasticity, and the magnet sheet 3 is attracted by its own attraction force. Only by doing so, the action of adsorbing to the empty can 10 can be obtained. On the other hand, in the case of separating the magnet sheet 3 attracted to the empty can 10 in this way, when the magnet sheet 3 attracted to the empty can 10 is moved in the separating direction while holding the end of the thin plate elastic body 2 as described above. The attraction force of the sheet becomes a resistance force against the detachment, first the central part of the thin plate elastic body 2 bends through its elasticity, and then the force of the detachment exceeds the limit of the attraction force, the magnet sheet 3 is instantly removed from the empty can 10. The thin plate-like elastic body 2 is vibrated by the reaction of being separated. Therefore, the presence or absence of magnetic force can be clearly identified by the feel of bending and vibration during this separation and during the above-mentioned adsorption.

[0013] Although some iron cans have a dull feel and are difficult to distinguish only by the attractive force of the magnet sheet 3, in the case of iron cans, the scratches rust when scratched. In such a case, rust can be easily found by enlarging the surface of the can with the magnifying lens 6 of the fifth embodiment (see FIG. 7). If there is rust, since it is an iron can, it is possible to determine the can material by the presence or absence of rust.

In the sixth embodiment shown in FIG. 9, ring-shaped rubber bands 8, 8 attached to both ends of the magnet sheet 3 are fitted to the tips of the palm and middle finger, respectively, as shown in FIG. The can material discrimination tool 1 can be attached to the palm. Therefore, unlike the first to fifth embodiments, it is not necessary to hold it with fingers, and there is an advantage that both hands can be used for work. By holding an empty can with the can material discriminating tool 1 attached to the palm in this manner, an action of adsorbing the adsorbed iron can to the magnet sheet 3 can be obtained by grasping the empty can while the iron sheet can be pulled away from the magnet sheet 3. The central part of the can is pulled by the iron can and bends forward due to its flexibility, and the presence or absence of magnetic force can be clearly discerned by the feel of pulling it apart.

In the seventh embodiment shown in FIG. 11, when the glove 9 is fitted on the hand, the magnet sheet 3 or the magnetic powder coating surface fixed to the palm portion is located at a position corresponding to the palm of the operator. By holding the glove 9 in the hand and gripping the empty can in this way, the same operation as the sixth embodiment can be obtained.

[0016]

[Effect of device]

 The present invention is configured as described above. As described above, the thin sheet elastic body is biased to at least one end to fix the magnet sheet, and the magnet sheet is attracted to or separated from the iron can. By flexing or vibrating the thin plate-like elastic body at the time, the presence or absence of magnetic force of the magnet sheet can be clearly identified by the feel of the bending or vibration, which facilitates the discrimination of the can material. I was able to do that. In addition, by bending or vibrating the thin plate-like elastic body in this way, the movement is interesting, and it has become possible to make children perform the discrimination work with interest. More specifically, when the magnet sheets are fixed to both the front and back surfaces of the thin plate elastic body as in the second embodiment, both the front and back surfaces can be used, and the thin plate elastic body as in the third embodiment can be used. When the magnet sheets are fixed to both left and right ends of the body, the left and right sides can be used, and the thin plate-like elastic body where the magnet sheet is not fixed can be narrowed as in the fourth embodiment. When formed, the bending or vibration can be made smoother. In addition, since the magnifying lens is fitted to a part of the thin plate-like elastic body, it is possible to visually confirm the presence or absence of rust through the image magnifying action of the magnifying lens. Came to. Further, since the magnet sheet formed so as to be flexibly deformable can be attached to the palm portion, specifically, both ends of the strip-shaped magnet sheet having appropriate flexibility as in the sixth embodiment. It is possible to attach a magnet band to the palm part of the glove by attaching a mounting band to the part so that the magnet sheet can be attached to the palm part by the band, or a magnetic sheet is attached to the palm part of the glove as in the seventh embodiment. By applying a mixture of body powder and adhesive, it is possible to clearly identify the presence or absence of magnetic force by the feel of a magnet sheet that is pulled by an iron can and curved, or when the surface coated with magnetic body powder is separated. It has become possible to solve the problem that the feeling of feeling becomes dull when holding a magnet with a hand as in the past.
