Description

[0001] The invention relates to a suction roll.

[0002] A suction roll, which is used for dewatering web material, for example in paper machines, has a metal roll shell provided with openings and at least one suction box inside. The suction box is mounted stationary inside the suction roll, with the perforated roll shell rotating around the suction box. To seal the suction box from the roll shell, the latter has sealing strips on the sides that seal the interior of the suction box from the remaining volume of the suction roll, specifically in the longitudinal direction of the suction roll. In the circumferential direction of the suction roll, the suction box is limited at both its ends by format limiters and sealed from the roll shell.

[0003] Sensors and actuators can be present inside the suction roll, which are connected to a control unit located outside the suction roll and which are to be supplied with electrical energy.

[0004] DE102004059028A1 discloses a sealing strip system with a wear indicator device.

[0005] EP0990865A2 relates to a measuring system for determining the moisture content of a fibrous web. A transmitter and receiver together form a sensor, with the receiver receiving light or radiation from the transmitter. The transmitter does not transmit data to the receiver, but rather an auxiliary energy source, which, after passing through the material web (or after reflection from the material web), is present as a measurement signal at the receiver's input. The auxiliary energy source itself does not contain any data. A measured value is only available at the receiver's output.

[0006] For example, it is known from US2017254019 (A1) and US2017254020 (A1) by the applicant to arrange temperature sensors inside the suction roll, which are arranged on a circuit board together with a battery and a microchip. The microchip is equipped with a radio module so that it can transmit data to a miniserver located outside the suction roll. It has been found that direct radio transmission from the radio module to the miniserver can be subject to signal interference.

[0047] According to the prior art, it is known to position a radio receiver outside the suction roll, which receives the data from the sensor units 3 via radio. The disadvantage of this is that the radio transmission is disrupted by the metallic roll shell.

[0048] As an improvement according to the invention, it is proposed to position the radio receiver inside the suction roller.

[0049] It is known from the prior art to provide the sensor unit 3 with a battery so that wiring within the sealing strip 1 can be omitted. The disadvantage of this is that the battery can become empty.

[0050] As an improvement according to the invention, it is proposed to provide the sensor unit with a receiver for wireless energy transmission and to provide a transmitter for wireless energy transmission in the vicinity of the receiver.

The sealing strip system consists of a sealing strip 1 which is movably received in the groove of a sealing strip holder 8. In the groove, below the sealing strip 1, there is an adjusting element 9, designed, for example, as a pressure hose. In front of the sealing strip 1, the sealing strip holder 8 is provided with a lubricant system which has spray nozzles 10, via which the lubricant, in particular lubricating water, is introduced through a spray pipe 11, for example integrated into the sealing strip holder 8.

At least one sensor unit 3 is preferably integrated or inserted into the sealing strip 1. The adjusting pressure with which the sealing strip 1 is pressed against the inside of the roll shell 6 in the front area can be changed via the pressure in the adjusting element 9.The sealing strip 1, for example, has a curved upper surface, so that the upper surface rests against the roll shell 6 in its front area and forms a gradually increasing gap with the roll shell 6 in the rear area. The width of this gap can be adjusted by a height-adjustable bar, which can move the rear end of the sealing strip 1 closer to or away from the roll shell 6.

[0056] A symbolically represented sound sensor 14 or a pickup can be mounted on or in the sealing strip holder 8, which serves to measure the noise level at or after the sealing strip 1. The sound sensor 14 preferably has a radio module.
