Description

GERMAN

It is well known that the filter respirators used in mining require constant careful work Check for readiness for use as well as permanent maintenance and care. They therefore do not remain in possession of the equipment wearer, but are only given to him for the shift. Be between layers they checked and cared for. This work as well as the issue and return of the filter breathing apparatus, What was previously required a relatively large amount of time, take place in filter stations. These don't require you Insignificant expenditure on space and personnel, as the following conditions are taken into account when setting up Need to become:

The station should be set up in such a way that the equipment attendant takes care of the care and maintenance of the filter breathing apparatus does not need to leave his room. At the removal and return points As much space as possible should be available so that all filter respirators are numerically strongest Layer can be accommodated. The filter breathing apparatus should be clearly stored so that The equipment operator can observe the processes at the removal or return point from anywhere in the station can. There must be a counter at which rejected filter breathing apparatus can be returned and on which the issue and return of the items provided for employees and visitors Filter takes place.

From these conditions it can be seen that a considerable effort is required for the filter station is, if only so that the equipment attendant can monitor the removal and return of the equipment. Nevertheless cannot be avoided with certainty that unchecked or non-serviced devices are issued will. For receiving, storing and dispensing the filter breathing apparatus in the filter stations shelves of various training are already known, z. B. in the form of slide shelves and around their axis rotatable round shelves, but the filter respirators are not stored on the same shelf stored and removed from it for use. These shelves also do not have any safety devices that allow unchecked removal Prevent devices.

The invention is based on the task of building filter stations in order to save Simplify manpower, space and time and reduce the possibility of errors due to human error must be switched off so that the miner or others can be equipped with a filter breathing apparatus Persons always come into possession of a tested and properly working device. In addition, these people should take care of the removal and return of the filter respiratory protection shelf device to record

and output of filter breathing devices

has been named as the inventor

Do not wait in queues for devices, but take possession of your filter respirator or use it immediately can return.

The invention relates to a shelf device for receiving and outputting filter breathing apparatus for mining and consists in the fact that the shelves with devices that can be unlocked by keys are provided, the z. B. are electrically controlled so that they only use the filter respirator lock every second entry in the compartment against removal, so that after use checked and in the Devices set in the compartment can be removed directly from this. According to the invention is therefore for the output and reception of the filter breathing apparatus is only required on a single shelf. By The advantages achieved in the invention are mainly that through the locking devices arranged on the shelf Possible errors that are based on human error are largely eliminated and it is guaranteed that the miner only uses a properly checked and cleaned filter breathing apparatus receives at the beginning of the shift. The space required for the filter station is also reduced; a monitoring of the removal and return by the equipment attendant is also not more required.

In a preferred embodiment of the shelf according to the invention are also control means, such as Lamps connected to the locking devices to indicate that the ready-to-use filter respirator

device is ready for removal, shelf is standing or removed has been. According to a further proposal of the invention, further control means with the Locking devices connected to indicate that the used filter respirator after unlocking the locking device has been removed from its shelf for maintenance and care. Are finally control means connected to the locking devices, which indicate that the used one is also expedient Filtered breathing apparatus has been put back into its compartment at the end of the shift. This way enables the invention in the simplest way the monitoring of the output and return of the filter breathing apparatus and also prevents unchecked filter respirators from being issued.

Usually the filter respirators are numbered, so it is further suggested that each To provide the shelf with a number and to arrange the same number on the filter breathing apparatus, so that each filter respirator is assigned a special shelf from which the miner regularly removes his device and into the he puts it back in.

A special proposal of the invention is that at the same time with the removal and return of the Filter breathing apparatus a time stamp is printed on a registration strip via a time printer, which shows when the device was removed or reset. In this way the device designed according to the invention can also be used to control working hours. So she takes on a task that is otherwise the responsibility of the driver.

In the following the invention will be described with reference to an embodiment shown in the drawing further explained. It shows

1 shows a compartment of a shelf device according to the invention,

FIG. 2 shows, in a reduced representation, a detail from a shelf device and FIG

FIG. 3 in conjunction with FIG. 4 shows a circuit arrangement for the locking devices according to the invention trained shelf device.

The shelf device shown in the figures is used to output and accommodate filter breathing protection devices 1. Relay boxes 2 'are arranged above the shelves 2. The individual shelves 2 are according to the invention provided with locking devices 3 loaded by springs 3 a, which are shown in FIG. 1 in the open State, are shown in Fig. 2 below and in Fig. 3 in the closed state. These locking devices 3 are controlled by an electrical control device, the details of which can be found in FIG are controlled so that used after setting Filter breathing apparatus 1 their removal for maintenance by the equipment attendant only after unlocking using a key to be inserted into the keyholes 7 is possible. If the device under test is returned to the Shelf is put back, so the locking device not activated. It can therefore easily be removed from the shelf 2 again by the user will. Fig. 2 shows a device that is ready for removal is indicated below or Fig. 3, locked. Each shelf 2 is provided with a number 8; the the same number is located on the filter respirator. The shelves are also with indicator lights 5, 6 provided, of which the lamp 5 indicates that there is a tested device in the shelf compartment, while the lamp 6 indicates that the filter respirator has been reset after use.

In the exemplary embodiment, the blocking and the other control measures are carried out by an electrical control device. In FIG. 4, which schematically shows the electrical control device for a shelf for holding a filter breathing apparatus, the locking device is in the idle state, that is, it does not block the path for setting a filter breathing apparatus. The voltage is applied, the key is removed and the contact 7 'is thereby closed. Lights 5 and 6 are also extinguished. By setting a tested, ready-to-operate filter breathing apparatus by the equipment attendant, the contact 4 is loaded, the lamp 5 lights up, the auxiliary relay RA picks up and prepares the current path for the auxiliary relay RB , that is, the contact ra closes The filter breathing apparatus 1 is removed from the miner or another person to be equipped with the filter breathing apparatus 1, so the contact 4 is relieved. He goes back to rest position. The lamp 5 goes out. The auxiliary relay RB picks up via the contact ra, which is closed for about 100 milliseconds after the relay RA has been de-energized, and remains energized even after the opening of ra via the contact rb I closed by itself, thereby actuating contact rb II.

After the end of the shift, the filter breathing apparatus 1 is placed back in the corresponding shelf compartment 2 and consequently the contact 4 is loaded again. The lamp 6 lights up via the contact rb II closed by the relay RB . At the same time, the auxiliary relay RH picks up, which switches on the locking devices 3 via two separate contacts rh I and rh II.

Switching on the locking devices 3 prevents the device 1 from being removed again. It can only take place if the equipment attendant puts his key in the keyhole 7. By inserting the key, the contact 7 'is opened and the lamp 6 goes out. The auxiliary relays RB and RH return to their rest position; thus the locking devices 3 are switched off via the contacts rhi and rhll. If the key is withdrawn in this state, the contact 4 is still loaded, the lamp 5 lights up again, the above-described state is present. If, however, the filter respirator 1 is removed, the retirement described at the beginning prevails after the key is withdrawn. The possibility of arranging a time printing unit 9 is indicated in FIG. The arrangement can also be made in such a way that the time pressure unit does not respond when the machine operator removes the device.

In Fig. 3, the function of the circuit is further explained by registered circuit reference numerals.
