Description

  The present invention relates to an iron scrap cleaner, and in particular, can efficiently recover iron scrap such as cutting scrap generated when cutting a workpiece in a machining factory or the like and scattered on a floor surface without power. It is related with the made iron scrap cleaner.

When machining a workpiece with a machine tool such as a cutting machine in a machining factory, iron scraps such as chips are scattered on the floor of the factory, and the worker is injured by the scattered iron scraps. The environment is getting worse.
For this reason, conventionally, a worker has to perform a cleaning operation in which the scattered iron scraps are collected or collected by scissors periodically or arbitrarily.
However, in this way, cleaning and recovery with a hoe by a worker also collects earth and sand and other dust falling on the floor surface together with iron scraps such as cutting chips of the workpiece. It is desirable to separate and collect the iron scraps and dust in order to recycle the collected scraps. .

For this reason, in order to collect iron scraps such as chips of workpieces scattered on the floor without using a hoe, and to separate and collect iron scraps such as chips and other dust at the time of recovery, patent literature The iron piece cleaning tool shown in 1 is proposed.
The iron piece cleaning tool shown in Patent Document 1 is composed of a non-magnetic outer cylinder whose one end is closed, and an inner cylinder which can freely slide inside the outer cylinder and has a magnet attached to the tip. The magnet at the tip of the iron piece cleaning tool is opposed to the floor surface to magnetize the iron scraps scattered on the floor surface, and then moved to the iron scrap collection position to move the inner cylinder to the outer cylinder by the force of the spring. By moving in the longitudinal direction, the magnetic force of the magnetized iron scrap is released, and the iron scrap is dropped and collected.
In this iron piece cleaning tool, the amount of iron scrap scattered once on the floor surface is a relatively small area of only the magnet attached to the tip of the inner cylinder. What is the recovery amount of iron scrap scattered on a large floor surface? There is a problem that it is necessary to operate again and again, and the recovery efficiency is poor, and it takes time to recover the iron scrap on a large floor surface.

In addition, the iron scrap collector shown in Patent Document 2 is configured by attaching a magnet to the tip of a shaft that is movable under the pressure of a spring in the outer cylinder, and the shaft is pushed into the outer cylinder at the time of iron scrap collection. In this state, iron scrap is magnetically attached to the outer cylinder surface and moved to the recovery position, and then the magnet is moved to forcibly release the magnetic force of the iron scrap that has been magnetically attached, so that it is dropped and recovered. .
For this reason, as with the iron piece cleaning tool shown in Patent Document 1, the amount of iron scrap collected once is only the area of the magnet attached to the tip of the shaft, and the iron scrap scattered on the floor surface cannot be efficiently recovered. There was a problem that it took time to recover the scraps on the surface.

Further, the iron scrap collector shown in Patent Document 3 accommodates an inner cylinder in an outer cylinder so as to be movable in the axial direction of the outer cylinder, and alternately arranges magnets and spacers in the inner cylinder. Rollers are arranged on the cylinder so that the floor surface can be moved.
For this reason, since the iron scrap collector can be moved along the floor surface, there is an advantage that iron scrap scattered on the floor surface can be efficiently recovered as compared with the iron piece cleaning tool and the iron scrap collector shown in Patent Documents 1 and 2. .
However, when discharging the collected iron scraps, it is necessary to pull out the inner cylinder from the outer cylinder near the floor surface. There is no choice but to install a roller.
For this reason, there existed a fault that the space | interval of a floor surface and an outer cylinder became large, and there existed a problem that it became impossible to endure the cleaning of the rough floor surface where iron scraps scattered with the small roller.

In view of the problems of the iron scrap cleaner, an object of the present invention is to provide an iron scrap cleaner that efficiently collects iron scraps such as cutting scraps scattered on the floor surface without power. .

  In order to achieve the above object, a scrap metal cleaner of the present invention includes a hollow outer cylinder, an operation member that is slidable in the outer cylinder along the longitudinal axis direction, and a distal end portion of the operation member. And a non-magnetic material in a shape that is arranged at the tip of the outer cylinder, covers the outer surface of the magnet, and allows the magnet to move along the longitudinal axis of the operating member. It is characterized by comprising a cover formed and rollers mounted on both sides of the cover so as to be able to roll on the floor surface.

  In this case, the cover front end surface can be bent so as to have a gap between the cover front end surface and the floor surface when the roller rolls on the floor surface.

  Further, a protrusion for forcibly removing iron scraps magnetically attached to the cover surface can be provided on the outer surface of the cover.

  Further, the roller can be moved on the both side surfaces of the cover in the longitudinal direction of the outer cylinder so that the gap with the floor surface can be adjusted.

  According to the iron scrap cleaner of the present invention, a hollow outer cylinder, an operation member that is slidable along the longitudinal axis in the outer cylinder, and a magnet disposed at the tip of the operation member And a cover that is disposed at the end of the outer cylinder, covers the outer surface of the magnet, and is formed of a non-magnetic material in a shape that allows the magnet to move along the longitudinal axis direction of the operation member; Since the scrap scraper can be moved freely along the floor surface by arranging it on both sides of the cover and mounted on the floor so as to be able to roll, a large area can be obtained. Iron scraps can be efficiently recovered even on the floor surface, and iron scraps can be discharged simply and reliably simply by moving the operating member.

  In addition, when the cover front end surface is rolled on the floor surface with a roller, the angle with respect to the floor surface of the iron scrap cleaner is formed by bending so that there is a gap between the cover front end surface and the floor surface. Even if it changes, iron scraps can be reliably collected.

  In addition, by providing a protrusion on the outer surface of the cover for forcibly removing iron scraps magnetically attached to the cover surface, the cover surface can be obtained simply by moving the magnet disposed at the tip of the operating member within the outer cylinder. Since the magnetic force is forcibly released at the position of the protrusion, the iron scrap that has been magnetically attached to the surface of the iron scrap is surely separated from the cover surface and dropped and can be recovered reliably.

  In addition, by moving the roller in the longitudinal direction of the outer cylinder on both sides of the cover and making the gap with the floor adjustable, the gap with the floor can be changed, so large iron scraps can be turned into small iron scraps. Can be collected selectively and reliably.

It is a front view which shows one Example of the iron scrap cleaner of this invention. It is the same side surface longitudinal cross-sectional view. It is an expanded sectional view showing at the time of adsorption work of iron scrap. It is an expanded sectional view showing the time of separation and recovery of iron scrap.

  Embodiments of the iron scrap cleaner according to the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the iron scrap cleaner according to the present invention.
As shown in FIGS. 1 to 2, the iron scrap cleaner A according to the present invention is suitable so that an operator can collect iron scraps such as swarf scattered on the floor surface in an easy-to-hold posture. A hollow outer cylinder 1 having a length, an outer diameter, and a cross-sectional shape as required, and an operation member 2 fitted inside the outer cylinder 1 so as to freely slide along the longitudinal axis direction thereof. The magnet 6 is attached at the tip of the operation member 2 so as to face the floor surface at a certain area at a time, and is disposed at the tip of the outer cylinder 1, covering the outer surface of the magnet and covering the inside. Cover 3 made of a non-magnetic material in which the magnet is movable along the longitudinal axis direction of the operation member, and a roller disposed on both sides of the cover 3 and mounted on the floor so as to be able to roll. 4 and 4.

The operation member 2 is set to be longer than the entire length of the outer cylinder 1 so that the tip of the operation member 2 protrudes slightly from the end of the outer cylinder, and a magnet 6 is attached to the tip of the operation member.
As shown in FIG. 1, the magnet 6 can be directly attached to the distal end portion of the operation member 2, but the magnet mounting base 61 is welded to the distal end portion of the operation member or fixed by other methods. Then, one or a plurality of magnets 6 are fixed to the magnet mounting base 61 by fixing or other methods.

In this case, as shown in FIG. 3, the magnet 6 is arranged in such a manner that even if the iron scrap cleaner A is in contact with the floor surface at a certain angle, iron scraps such as chips scattered on the floor surface are magnetized. For ease of explanation, the magnet mounting base 61 is formed by bending the central portion at a right angle to the axis of the operating member 2 and the both side portions thereof being inclined at a certain angle, and a magnet is mounted on each surface of the magnet mounting base 61. 6 is stuck.
In addition, it is also possible to form the magnet mounting base 61 so as to be bent along the outer periphery of the roller with a smaller diameter than the roller diameter without being bent.

The magnet mounting base 61 is formed so as to protrude long in the lateral direction with respect to the axis of the operation member 2.
The horizontal width of the magnet mounting base 61 is not particularly limited so that iron scraps such as swarf scattered on the floor surface in a certain area at a time can be magnetized, but it is, for example, 30 cm or more. This makes it possible to collect iron scraps on a large floor area at a time.

The cover 3 disposed at the distal end portion of the outer cylinder 1 is formed of a non-magnetic material, and is disposed at the distal end portion of the operation member 2 when the operation member 2 slides along the longitudinal direction of the outer cylinder 1. Arrangement of the magnet 6 in which the provided magnet 6 is shaped so that it can move over a predetermined range in the cover 3 and the shape of the tip portion facing the floor surface of the cover 3 is adhered to the magnet mount 61 It forms so that it may become a shape, and it covers the outer surface of the magnet 6 completely.
Thereby, when the operation member 2 is in the depressed position, the magnet 6 is disposed along the inner surface of the front end portion of the cover 3 and preferably in contact with the inner surface of the front end portion of the cover 3. The magnetic force of the magnet 6 acts strongly to the outside through the tip of the cover 3.

Rollers 4 and 4 are disposed at the left and right side surface positions of the cover 3 formed of this nonmagnetic material.
The outer diameter of the roller 4 is set so as to be larger than the outer shape of the tip of the cover 3 as shown in FIGS. 3 to 4, so that the rollers 4 and 4 roll along the floor surface. In addition, a gap C is formed between the tip of the cover 3 and the floor surface so that the cover 3 does not contact the floor surface F.
By forming a gap C between the front end portion of the cover 3 and the floor surface F, iron scraps 7 such as chips scattered on the floor surface can be easily magnetically attached to the lower surface of the front end of the cover. it can.
Further, on the side surface in the longitudinal direction of the cover 3, when the magnet 6 moves upward in the cover 3 and reaches a predetermined position due to the movement (backward movement) of the operation member 2, the cover is covered by the magnetic force of the magnet 6. The iron scrap 7 that has been magnetically attached to the outer surface 3 is released from the magnetic adhesion force and is surely dropped from the outer surface of the cover 3, and a protrusion 5 for discharging the iron waste is attached.

Next, the operation of the iron scrap cleaner will be described.
As shown in FIGS. 1 and 2, the operation member 2 is pushed down so that the magnet 6 is positioned along the inner surface of the tip of the cover 3, and the roller 4 is moved on the floor surface with the vicinity of the upper end of the outer cylinder 1. When the iron scrap cleaner A is rolled and moved, the iron scrap 7 such as chips scattered on the floor surface F is magnetically attached to the outer surface of the cover 3.
In this case, as shown in FIGS. 3 to 4, the shape of the tip of the cover 3 is bent with respect to the floor surface. The iron scrap 7 such as chips scattered on the floor surface F is magnetically attached by the magnetic force of the magnet 6 in the cover 3 regardless of the angle of the outer surface of the cover 3 with respect to the floor surface. Since the width is made larger than that of the conventional product, the iron scrap 7 can be magnetized with a large area by one movement.

In this way, the iron scrap 7 is magnetically attached, and when a predetermined amount of iron scrap 7 is magnetically attached to almost the entire outer surface of the cover 3, the iron scrap 7 is separated and collected.
At the time of separating and collecting the iron scrap, if the operation member 2 is pulled out from the upper end of the outer cylinder 1, the magnet 6 moves upward in the cover 3 as shown in FIG. The magnet 6 comes away from the inner surface, and the iron scrap 7 adsorbed on the cover 3 loses the adsorbing force due to the magnetic force and falls off the surface of the cover 3.
At this time, the iron scrap 7 adhering to the side surface of the cover 3 is also forcibly removed by the protrusion 5 for discharging the iron scrap.

In addition, the cover 3 is formed so as to be bent along the shape of the roller 4, and the magnet 6 is also arranged along the inner surface of the cover 3, so that it is adsorbed depending on the angle with respect to the floor surface of the iron scrap cleaner A during use. The power does not change and iron scrap can be collected efficiently.
Furthermore, by making the attachment position of the roller 4 adjustable in the longitudinal direction of the outer cylinder 1, it is possible to cope with various sizes and magnetic iron scraps scattered.

  As mentioned above, although the iron scrap cleaner of the present invention has been described based on the embodiments thereof, the present invention is not limited to the configurations described in the above embodiments, and the configurations are appropriately set within the scope not departing from the gist thereof. It can be changed.

  Since the iron scrap cleaner of the present invention has a characteristic of efficiently recovering scraps such as cutting scraps scattered on the floor surface without power, it is preferably used for the application of the iron scrap cleaner. In addition, for example, it can be used for iron scrap cleaning at welding sites that are easily contaminated with iron powder, and for scrap scrap collection on roads and grounds.
