Circuit arrangement for measuring the occupancy of a defect with laundry items

Application of the invention

The invention relates to a circuit arrangement for measuring the occupancy of a defect with items of laundry in order to reduce energy consumption, wherein the defect has at least one processing path and each processing path is assigned in each case a scanning element.

Characteristic of the known technical solution

It is already a trough deficiency with a device for measuring the occupancy of laundry mangles with laundry (PE-OS 29 12 965, Int Cl: D 06 P, 67/00) known. With this device, the number of revolutions of the mangle cylinder are counted and displayed "Furthermore, the device detects the laundry rolls passing through the mangle rolls." Likewise, in this device, the number of revolutions of the shortage cylinder is counted only.

when laundry is detected by the Albtasteinrichtung. The counting result is displayed in a display device next to each display of the number of revolutions of the mangle cylinder and the number of garments passed through the garnish »

Since üie location of the laundry items on the conveyor is not poaitionierbar in each case to the position of the cylinder arranged on the mangle, errors occur in the detection, which add up and thus provide false readings or deviations.

Because of the relatively low frequency of the pulses emanating from the pulse generators arranged on the short cylinder, relatively large errors occur. Since the number of errors is inversely proportional to the number of arranged on the mangle cylinder pulse, the error size can be limited by a larger number of pulse generators. However, this is associated with a higher cost and considered disadvantageous.

Aim of the invention

The aim of the invention is to provide a circuit arrangement for measuring the occupancy of a defect with laundry items, in which the occurrence of errors is largely excluded and influence on the specific energy consumption of the defect is taken.

depicting the essence of the invention

The invention has for its object to provide a circuit arrangement for measuring the occupancy of a defect with laundry, which operates independently of speed, and to reduce the specific energy consumption of the defect.

This object is achieved ex'findungsgemäß in that a circuit arrangement for measuring the occupancy of a defect with items of laundry in order to reduce energy consumption, the defect has at least one processing path and each processing path in each case a scanning element »is arranged _{9 is} created, which is characterized that the the ßearbeitungsbahn assigned and the time detected in the direction of movement of the advancing laundry pieces in each case between the end edge of a laundry article and the leading edge of the following laundry article sensing a common mode switch downstream ists that this mode switch at least two block circuits _s are arranged downstream of each block circuit comprises a comparison module, in which the comparison between the sum of time intervals ( ¹¹ lst "value) coming from a summer and a comparison value given by a desired value generator is internally lb of a viewing period given by a viewing spatial evacuator, and upon reaching the comparison value, the specific energy consumption of the lack of washing can be influenced and the observation period of the observation period generator of the following block circuit is constantly greater than the observation period of the observation period generator of the allocated block circuit and that of a block circuit with the summer of the respective one Block circuit is associated with associated comparison block (timer), which is connected to a switch-off the defect.

The mode selector switch can be influenced externally. Furthermore, the switch-off the defect is additionally externally influenced. The block circuits influencing the specific energy consumption of the defect are also assigned delay modules »

In this circuit, the detection of the timing pulses by corresponding sensing elements «. This time-

Pulses are fed separately via an externally, according to the number of processing paths, operable mode switch a summer, the all time intervals added «In Blockschaltiingen, which have a Vergleiehsbaustein, a setpoint generator, a viewing Seitraumgeber and a summer, the comparison of the sum of the time pulses with the reference value within one observation period. If the sum of the time intervals reaches and / or exceeds this comparison value within the observation period, the delivery of information to the operating personnel by a display device takes place depending on the time duration of the achievement and / or the exceeding of the predetermined comparison values and the observation periods, furthermore influencing the specific energy consumption until decommissioning the defect.

By the solution according to the invention, the detection of the unused evaporation performance takes place in which seen in the direction of movement of the laundry, spaces are detected as time (time) and compared with a predetermined reference value within a predetermined observation period and its exceeding and / or reaching a signal - And / or tripping function to influence the specific energy consumption takes place.

By recording the intervals as a time variable, a speed-independent operation is possible. The sensing elements can therefore be located at any point of the defect or within the deficiency line, regardless of the fact that different working speeds are within a deficiency line * This circuit helps to reduce the specific energy consumption of the deficiency _o

The? Ash defect is a palt device which essentially has a conveyor 14 and a rolling-folding device 15 located downstream of it. Above the conveyor 14 ₉ , between the tray deficiency exit and the skimming folder 15, encoders 165 are arranged 17 "18", preferably photo ™ electrical sensing elements _$

In order to dry and smooth the laundry items in the trough deficiency, it is necessary the laundry items 34 with the help of the rotational movement of the mangle cylinder 5 »6 with the flat surfaces of the heated mangle troughs 2; 3 to bring into contact. The resulting vapors are sucked into the interior of Mangelzvlinder 5 »S and suction lines 10; a fan 13 is supplied. In this case, both this exhaust air can be partially fed back to a dump provided with a heat-insulating housing or also the heat energy present in this exhaust air is used for the heating of the fresh air to be supplied to this laundry.

In order to further reduce the specific energy consumption, that is the consumption of energy, in particular heat and electric energy, per kilogram in the lack of dried laundry, it is necessary to minimize the unused evaporation performance. This unused evaporation performance is especially in the free spaces between the laundry items, in each case between the end edge 34 a and the beginning edge 34 b of the following laundry item 34th

However, it also recognizes the possibility that the tray shortage has fewer or more than three machining tracks. The time intervals detected in the first processing binafilter will be referred to as t * and the time intervals recorded in the last working paper as t _n.

These determined time intervals t *, t ₂ and t, are separately fed to a mode switch 19, «This mode switch 19 is preferably by an external actuation, for example by the Vorwahlaystem one of the Fäschemangel assigned input or folding machine, switchable to sine other number of processing paths. The time intervals t-, t "and t ~ are in turn forwarded separately to the adder 20. In this adder 20, the addition of the data from the encoders 16 takes place; 17 and 18 determined time intervals t ^, tg and tj in the first viewing period given by the observation room 22, After the first viewing period, the sum of the time intervals t ^, tg and t »is set to zero. It starts again the addition of the time intervals tj, tg and t ~. Parallel to this, the sum of the time intervals t-, t "and tin is input to the comparison block 21 and a comparison with the comparison value specified by the setpoint generator 23 'is performed. If the sum of the time intervals t-, t" and to reaches the comparison value and / or if it exceeds the comparison value specified by the setpoint generator 23, information is immediately sent to the operating staff by means of a display device 24 when the comparison value is reached. This information can be given optically, acoustically or in combination. The display device 24 is switched off again after the first Betraohtungszeitraumes.
