A woodworking machine operator engaged in the processing of workpieces.

1.2. Hazardous and harmful production factors: moving machines and mechanisms, moving parts of production equipment, moving products, workpieces, materials, increased noise level at the workplace.

Sources of factors: rotating knife shafts, rotating knife heads, rotating feed rollers, moving feeders, rotating belt drives, workpieces fed into the machine; processing process.

Effect of factors: possible contact with rotating and moving parts of the machine, the possibility of breakage and escape of knives, the possibility of reverse departure of workpieces; negative impact of noise on the hearing organs.

1.3. Personal protective equipment: cotton suit; goggles; hearing protection.

2. Safety requirements before starting work

2.1. Check the correct installation and fastening of the knives. The blades of the knives should protrude beyond the edge of the clamping wedge chipbreaker by no more than 1,5 mm, the knives describe circles of the same radius.

2.2. Check that the feed and idler rollers and pressure jaws are correctly adjusted.

Corrugated rollers should not have cracks, worn surfaces, chipped ribs, ridges contaminated with resin and chips, which can lead to slipping of the rollers during operation and ejection of workpieces.

2.3. Check safety stops, additional curtains, lingering claws, sectors, slats. Safety stops must be lowered.

2.4. Check the condition of the knife shaft. The knife shaft must be cylindrical, balanced and free from runout in the bearings. Before starting the machine, the knife shaft must be closed with a casing.

Make sure that the knife shaft rotates in the same direction as the material.

2.5. Check the serviceability of the limits of the limiting section of the material in front of the feeder.

2.6. Check the serviceability of the brake device, grounding devices, blocking of the feed mechanism with the knife shafts of the machine, starting devices.

The feed mechanism is interlocked with the knife shafts so that stopping any of them causes the feed mechanism to stop.

2.7. Check the presence and serviceability of the cutting tool guards, falling mechanisms, belt drives.

3. Safety requirements during work

3.1. Feed blanks into the feed rollers without breaks, end to end.

3.2. Make sure that the thickness of the supplied workpieces is the same. Keep your hands away from the feed rollers.

3.3. If the workpiece is jammed in the rollers, stop the machine, after the knife shaft has completely stopped, remove the workpiece.

3.4. Processing of workpieces longer than 1,5 m is carried out using auxiliary tables or rollers installed in front and behind the machine.

3.5. The smallest length of the workpiece to be processed must be 100 mm greater than the distance between the axes of the feeder rollers.

3.6. Do not remove chips with a thickness of more than 2 mm in one pass.

3.7. Do not treat frozen wood and wood with large cracks.

3.8. Machine operators serving one machine should coordinate their actions, if necessary, reduce the feed rate.

3.9. Do not work in gloves. To protect your hands, use special handhelds.

3.10. Inspection, cleaning, wiping, checking the quality of processing parts, fixing fences, manual removal of waste from the machine should be carried out only when the knife shafts are completely stopped.

3.11. If there is a knock, vibration, change in the nature of the noise, overheating of the cutting tool, turn off the machine and inform the master.

4. Safety requirements in emergency situations

4.1. Turn off equipment.

4.2. Post a table about the malfunction of the machine or equipment and report this to the direct management.

4.3. In the event of a fire or extinguishing a flame, use a nearby fire extinguisher.

4.4. The victim or bystander must notify the appropriate work manager of each accident or poisoning.

4.5. The worker must be able to provide first aid. Such assistance is provided immediately, directly at the scene and in the following sequence: first you need to eliminate the energy source of injury (switch off the engine, stop the mechanism, remove the victim from under the car, a heavy object, etc.).

Assistance should begin with the most significant that threatens life or health (in case of severe bleeding, apply a tourniquet, and then bandage the wound; if a closed fracture is suspected, apply a splint; with open fractures, first bandage the wound and then apply a splint; in case of burns, apply a dry bandage ; in case of frostbite, gently rub the affected area using soft or fluffy tissues). If spinal injury is suspected, transport the victim only in the supine position on a rigid base.

4.6. After providing first aid, the victim should be sent to the nearest medical facility.

5. Safety requirements at the end of work

5.1. Turn off equipment. Wait for it to come to a complete stop. Tidy up the workplace: remove tools, fixtures; clean the machine from dirt and dust; wipe and lubricate the rubbing parts of the machine; neatly fold the finished parts and the remaining material.

5.2. Cleaning of wood waste (sawdust, shavings, dust) from the surface of the equipment, as well as from overalls, is carried out with a brush, sweep or using vacuum cleaners.

It is unacceptable to blow the machine and clothes with compressed air.

5.3. Rags used during work and when cleaning, put the rags in a special metal box with a closing lid and take it outside the workshop to a specially designated place.

5.4. Wash hands with warm water and soap.

5.5. Report all noticed shortcomings in the operation of the equipment to the shift worker or foreman.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Safe magnetic socket 03.08.2005

German engineer Klaus-Dieter Fritsch invented the electrical outlet with a plug. Yes, not simple, but safe. You can pick a nail in it, a child can stick a finger in it - nothing bad will happen. Contact occurs only when the plug of the electrical appliance is inserted into the socket.

The secret is in the magnets that are hidden in the socket and in the plug. The plug serves as a magnetic key to the socket. When the poles of the magnets match, voltage is applied to the socket contacts. If in a room, for example, in a laboratory or workshop, there are two electrical networks with different voltages, then by changing the location of the magnets in the plugs, you can make the outlet supply the voltage assigned to each device.

A small batch of magnetic plug-socket sets was ordered by Fritsch in Hungary and was successfully sold out. But the inventor does not have the funds to compete with the major manufacturers of wiring devices, and they do not want to rebuild the established production. True, automakers became interested in Fritsch's system.

Until now, the only "socket" for connecting electrical appliances in the car remains the cigarette lighter socket. The cabin and trunk of the new Volkswagen model will have several magnetic sockets for connecting a coffee maker, a portable TV, a fan, portable lamps and other electrical appliances.
