Abstract
A safety device 100 for use during metalworking has a screen 110 with an electromagnet 120 located on one side. The electromagnet produces a magnetic field 125 across the screen, which may capture metal chips 155 in use. A swarf collection tray 130 is located along the lower edge of the screen, e.g. by releasable attachment, such that the waste may fall into the tray when the electromagnet is de-energized. Communication means between the electromagnet and a metalworking tool 150 is provided. The electromagnet is adapted to switch on when the tool is being operated, e.g. to provide synchronised activation. The electromagnet is also adapted to switch off when the tool is idle or powered down, preferably with a delay so that in-flight chips are still captured. An LEV hood with a suspended electromagnet and removable collection tray is also disclosed (fig 3).
Description
A METALWORKING SAFETY DEVICE
FIELD
The present invention relates to safety equipment for metalworking, and more specifically, to the capture of metal dust and debris created during metalworking.
BACKGROUND
During metalworking procedures such as cutting, grinding, and welding etc., a significant amount of waste metal (also known as swan, chips, turnings, Rings, or shavings) may be generated and propelled outwards from the working piece. If left un-obstructed, the waste metal may spread out onto a working area floor or into objects in the near vicinity. These metal particles may be hot and therefore increase the risk of unwanted heating and possible fires.
Additionally the velocity of some of these particulates may cause a significant projectile hazard, for nearby machinery and even work-place suitable Personal Protection Equipment (PPE) may not fully protect an individual. The velocity also leads to a significant spread of waste material around the working area, which is a safety hazard for slips trips and falls. Additionally a build-up of metal dust over time can require costly clean up and work-place risk assessments. Metal dust contamination can be an issue for electronic devices, and so such electronic devices in the vicinity require higher ingress protection ratings. Additionally higher concentrations of airborne particulates can be hazardous to workers if not correctly captured.
To prevent injury, PPE is often worn as a safety precaution, and floor markings may be used to cordon off metalworking areas. However, these markings may be easily missed or ignored, and PPE may be incorrectly worn hence propelled metal particulates present a significant risk to bystanders or machinery operators' safety.
Local Exhaust Ventilators (LEVs) are also common-place in metalworking environments, but require significant work-piece encapsulation to enable pressurised air flow. Metal intake can drastically reduce the longevity of LEV devices, increasing the maintenance and filter replacement requirements. -2 -
The present invention aims to address these problems by providing an improved safety system adapted to capture, direct and collect projectile metal particulates generated throughout the metalworking process.
SUMMARY
According to first aspect of the present invention, there is provided a safety device for use during metalworking. The device comprises a (substantially upright) screen, an electromagnet located on one side of the screen, a collection tray along the lower edge of the screen, and communication means between the electromagnet and a metalworking tool. The screen prevents any lose metal particles or dust from escaping the metalworking area. The electromagnet is adapted to produce a magnetic field across the screen, and is also adapted to switch ON when the connected metalworking tool is being operated, and switch OFF when the connected metalworking tool is idle or off. The electromagnet therefore captures the metallic dust and particulate matter thrown into the air by the metalworking tool. The dust and particulate matter is also less likely to ricochet from the screen because of the magnetic field. When the tool, and therefore the connected electromagnet, is switched off, any captured metal dust or particulate matter falls into the collection tray at the bottom of the screen for easy collection and disposal.
In one example, whilst the electromagnet is adapted to turn on upon operation of the metalworking tool, so as to immediately capture any dust or particulate matter, the electromagnet is adapted to switch off after a short predetermined delay after the metalworking tool is idle or switched off. This ensures that any dust or particulate matter still inflight towards the screen when the metalworking tool is switched off is still captured by the delayed shut-down of the electromagnetic field.
In another example the metalworking tool and electromagnet are powered in series together, so that when the metalworking tool is powered-30 down, the electromagnet is automatically powered-down as well.
In a further example, the safety device also comprises weighing means, able to weigh the amount of collected dust or particulate matter collected by the electromagnetic field and suspended on the screen. When the weighing means -3 -calculates that the amount of metal dust is above a pre-determined value, the electromagnet is adapted to briefly switch off, and then back on again. This helps keep the safety screen clear of excessive debris, and able to collect more dust and particulate matter thrown from the metalworking tool, whilst periodically depositing any collected dust or particulate matter in the collection tray.
In another example, the safety device also comprises at least one angled slat across the screen, on the opposite side to the electromagnet, i.e. facing the metalworking area. The slats reduce the amount of any ricocheting dust or particulate matter by deflecting any incoming dust or particulate matter (preferably downwards towards the collection tray).
In another example of the invention, there is provided an LEV hood for use in a metalworking area. An air pump or fan draws air from the metalworking area through the LEV hood, and an electromagnet suspended within the LEV hood attracts and collects any metal dust or particulate matter in the airflow.
There is also a removable collection tray in the lower edge of the LEV hood, under the electromagnet. When the electromagnet is turned off, any collected metal dust or particulate matter falls into the tray, and can be disposed of.
BRIEF DESCRIPTION OF THE FIGURES Embodiments of the invention will now be described by way of example only with reference to the figures, in which: Figure 1 shows a schematic view of an example safety device comprising a screen and an electromagnet; Figure 2 shows a schematic view of an example safety device comprising a screen with directional slats and an electromagnet; and Figure 3 shows a schematic side-on view of an example safety device comprising a local exhaust vent with an integral electromagnet and collection tray.
DETAILED DESCRIPTION
Figure 1 shows a safety device 100 for use during metalworking. During metalworking, a significant amount of waste metal 155 is often generated in the -4 -form of metal dust and particles, and propelled outwards from the tools 150 as they are used. The safety device 100 comprises a screen 110 which is intended to contain any waste material 155 within the metalworking area. In the example shown, the screen 110 is substantially flat and substantially upright. However, it will be appreciated by the skilled person that other examples, such as curved, tilted, or multiple articulated screens may be employed in a similar manner to achieve the inventive effect described herein.
The safety device 100 also comprises an electromagnet 120 located adjacent to the screen 110, and preferably on the opposite side to which the metal working is taking place. In one example, the electromagnet is located between two outer screen edges, sandwiched there between. When activated, the electromagnet 120 generates a magnetic field 125 across the screen 110 which helps capture and prevent any of the ferromagnetic/ferrous metal dust and particles 155 from ricocheting off the screen 100. The ferrous metal dust and particles 155 are instead captured by the magnetic field 155, and held against the screen 110. The safety device 100 may comprise multiple electromagnets 120 in order to generate a suitable magnetic field 125 across the screen 110.
The safety device 100 also comprises communication means (not shown) by which to connect the metalworking tool 150 to the safety device 100, and specifically to the electromagnet 120. The communication means between the electromagnet and the metalworking tool may be wired or wireless. The activation of the electromagnet is synchronised with the operation of the metalworking tool 150. Therefore, when the metalworking tool 150 is being used, the electromagnet 120 is switched on, and any metal particles or dust 155 thrown from the tool 150 may be captured by magnetic field 125 surrounding the safety device 100. When the metal working tool 150 is idling, or switched off, then the electromagnet 120 is also switched of. Any collected dust or particulate matter will fall into the collection tray 130. In another example, the power to the electromagnet 120 switches off after a pre-determined delay after the metalworking tool 150 is not being used (e.g. idle or switched-off). This allows the safety device 100 to capture any ferrous metal particles or dust 155 that are still in flight as the metalworking tool 150 is switched-off. -5 -
In another example, communication means is enabled through the power connection between the electromagnet 120 and the metalworking tool 150. Operation of the metalworking tool 150 also controls the power for the electromagnet 120. It will be understood by the skilled person that whilst he example shows a user and a hand-held metalworking tool, the invention can similarly realised with a range of metal working tools, whether they are manually operated or un-manned.
The safety device 100 also comprises a tray 130 which runs along the lower edge of the screen 110. The tray may be either permanently attached to 10 the screen 110, or removeably attached for ease of emptying. To prevent unwanted magnetism, the tray may be made out of non-magnetic materials.
When the electromagnet 120 is deactivated, e.g. when the metalworking tool 150 is switched off or idling, any collected ferrous metal dust or particles will fall from the screen 110, and are collected in the tray 130. The collected ferrous metal dust and particles 135 can be easily removed and disposed of after the metalworking has been completed.
In the interests of usability, the safety device 100 may be relocated through mobility means such as wheels, or alternatively, the screens 110 may be hung from a railing system.
The screen 110 may be solid, or fabric/textile-based and supported by a rigid frame. In one example, the screen 110 is also made of a ferrous material, so that the electromagnet 120 induces a magnetic field in the screen 110 itself, thus becoming magnetic and aiding the attraction and collection of ferrous dust and particles 155.
In another example, the screen 110 is coated in a low-friction coating to assist any collected ferrous material falling from the screen 110 into the collection tray 130 when the electromagnet 120 is switched off Figure 2 shows a further example of the safety device 100 as described above, comprising a series of slats 140. In the example shown, the slats are arranged horizontally and angled so that any incoming ferrous particles 155 are deflected downwards, towards the collection tray 130. In one example the slats are made from a ferrous material, and a magnetic field is induced in the slats by the magnetic field 125. The slats 140 may also comprise a low-friction coating to assist the incoming dust and particles 155 being deflected from the slats 140, -6 -and not-sticking to them when the electromagnet 120 is turned off. The slats 140 may be curved or flat, and preferably are horizontally aligned and angled so that any incoming metal dust or particulate matter 155 is deflected downwards upon impact with the slats 140. However, in another example, the slats could be arranged at any angle, e.g. vertically. The slats 140 not-only help deflect incoming metal dust and particulate matter 155, but also help prevent any fast-moving metal dust or particles 155 from bouncing back off of the screen 110 onto the work floor. The slats 140 also help capture any non-ferrous dust or particles 155 generated by the metal working, since they are still deflected (preferably downwards), despite not being affected by the magnetic field 125.
The slats 140 should be arranged such that the angle, overlap and depth of the slats prevent any dust or particulate matter 155 ricocheting back off the screen 110 and onto the working floor. It will be appreciated by the skilled person that the slats 140 are arranged and overlapped in a suitable manner, e.g. the first edge of a first slat should overlap with the second edge of a second, adjacent, slat, then the particles and dust 155 are more likely to be caught by the slats 140 and screen 110 and fall to the collection tray 130.
The invention may also be realised wherein the screen 110 itself is curved, or angled downwards with respect to the metalworking area, so that any 20 fast-moving metal dust or particles 155 do no ricochet back to the metal working area.
In a further example, the safety device 100 is equipped with weight sensors. These can be implemented in a number of ways, for example in wheels supporting the safety device 100, or if the screen 110 is hung from a railing system, the weight sensors could be incorporated into the hanging means. The weight sensors are coupled to the electromagnet, and are adapted to turn the electromagnet (momentarily) off if they determine that the screen 110 has collected a pre-determined amount of metal dust and particles 155. When this occurs, the electromagnet 120 is temporarily switched off so that the collected dust and particulate matter falls into the collecting tray 130, and the electromagnet 120 can be quickly re-activated again Alternatively, or in combination with any of the electromagnet 120 power controls discussed above, the electromagnet 120 may be automatically switched off and back on again periodically, i.e. after a pre-determined time for -7 -example every 10 minutes, for 3 seconds, so that any collected ferrous metal particles or dust fall from the screen 110 into the collection tray 130.
Figure 3 shows another example of a safety device 200, comprising a local evacuation vent (LEV) hood 210. The LEV hood 210 is in fluid communication with a pump or fan 240 adapted to draw air through the LEV hood 210. The LEV hood 210 also comprises an integrated electromagnet 220 which is suspended in the centre of the airflow path through the LEV hood 210. The electromagnet 220 is preferably substantially bi-conic in shape, which causes an increase in the air speed within the LEV hood 210 allowing for greater capture of other nonferrous particles and dusts. In another example, the electromagnet 220 may be formed around, or incorporated within, the outer wall of the LEV hood 210.
The safety device 200 also comprises a removable or openable tray 230 beneath the electromagnet 220. As the fan or pump 240 draws air through the LEV hood 210, any ferromagnetic dust or particulate matter 255 is captured by the electromagnet 220. The electromagnet 220 can be adapted to turn on whenever the fan or pump 240 are activated, and de-activated when the fan or pump 240, are deactivated. When the electromagnet 220 is deactivated, any ferrous dust or particulate matter 255 falls from the electromagnet 220 into the collection tray 230. The collected dust and particulate matter 235 can be emptied when the tray 230 becomes full.
The electromagnet 220 may also be adapted to automatically turn off (and quickly back on again) whilst the fan or pump 240 are active, in order to quickly clear the electromagnet 220 of any captured ferrous dust or particulate matter 255. Furthermore, the electromagnet 220 may also comprises weighing means adapted to interrupt the power supply when a pre-determined weight threshold of accurately ferrous dust and particulate matter is reached, as described above.
The collection tray 230 is suitably deep enough, or the entrance comprises at least one angled slat (not shown) so that any collected dust or particulate matter is not drawn back out of the collection tray 230 when the fan or pump 240 is active. -8 -
