    However, the prior art solution presents problems. Separate cassettes are required for feeding samples. It is slow and difficult to place the samples in cassettes and to process the cassettes. The movement of the cassettes with the elevator principle is also slow, complicated and requires a number of moving parts. In addition, a number of limit switches, motors and I / O means are required to control the movements of the cassettes and the lift. It is slow and complicated to place the samples in cassettes, as the samples must be set at different heights and each cassette must be leveled to a suitable scaffold height before the sample is set in the cassette. It can also be difficult to follow the movement of the samples in the analysis, as it is difficult to see the different heights.
    Problems are also caused by the fact that cardboard samples and sheet samples that deviate from standard measurements cannot be measured.
    BRIEF DESCRIPTION The object of the invention is to realize an improved feeding device and a method. This is fulfilled by a feeding device, which is arranged to feed paper and / or cardboard samples for measurement in a measuring device.
    The feeding device comprises at least two successive feeding units, which are arranged to send a sample against a measurement performed in the measuring device, and the feeding device is arranged to transport a sample sent from at least one feeding unit past at least one feeding unit which is located as follows on the feeding route.
    The invention also relates to a feeding method for a measurement of paper and / or cardboard samples performed in a measuring device. In the method, a sample with at least one feeding unit of a feeding device is sent against a measurement performed in the measuring device; and the transmitted sample is guided past at least one feed unit which is located as follows on the feed route.
    The preferred embodiments of the invention are described in the dependent claims.
    A number of advantages are achieved with the method and the feeding device according to the invention. Several samples can be easily fed in successively and the need for moving parts and limit switches is small. It is easy to place a sample in place and the movement of the samples to the assay can be easily followed. In addition, cardboard samples and a sample base can be used in the measurement.
    DESCRIPTION OF THE DRAWINGS The invention is described in more detail below in connection with preferred embodiments with reference to the accompanying drawings, in which Figure 1 shows a side view of a feeding device, Figure 2 shows a feeding device obliquely from above, and Figure 3 shows a fate diagram of the method.
    DESCRIPTION OF EMBODIMENTS Let us first examine a feeding device using Figure 1.
    The feeding device 100 is intended to feed paper, cellulose and / or cardboard samples for analysis, which can be performed in a measuring device 102.
    The measuring device 102 can measure at least one property of the paper, cellulose or cardboard sample, which can be used e.g. in monitoring the quality of a manufactured product or a product to be manufactured and in controlling manufacturing or further processing processes.
    The feeding device 100 can be placed in front of the measuring device 102.
    The feeding device 100 comprises at least two feeding units 106 - 110, 150 successively in such a way that the feeding direction of each feeding unit 106 - 110, 150 is the same. This means that the feeding units 106 - 110, 150 can send a sample 116, 146, 156 against a measurement performed in the measuring device 102.
    The feeding device 100 may comprise a conveyor 114, which transports the sample 116, 146, 156 from the feeding unit 106 -110, 150 to the measuring device 102. In the feeding device 100, the sample 116, 146, 156 is fed onto the conveyor 114 towards the measuring device 102 with at least one of the feeding device 100 feed units 108 - 110, 150. The sample 116, 146, 156 transported by the conveyor 114 can pass at least one second feed unit 106 - 110, which is located on the feed route between at least one feed unit 108 - 110 , 150 and the measuring device 102.
    The conveyor 114, which may comprise one or more conveyor belts, a roller set, a wheel set, etc. successively and / or in parallel, may transport the sample 116, 146, 156 to the possible receiving opening 104 of the measuring device 102 or even something (a small blank) inside from the receiving port 104 for measurement. The feeding device 100 may comprise in connection with each feeding unit 106 - 110 a feed switch 1240 - 1280, which is based on a pressure unit 124 - 130 and the conveyor 114. When the pressure unit 124 - 130 presses the sample 116, 146 against the conveyor 114, the supply switch 1240 - 1280 is considered closed. The supply switch 1240 - 1280 can be closed when it is desired that the sample 116, 146, transported by the conveyor 114, should go towards the measuring device 102. Otherwise, the supply switch 1240 - 1280 may be open, whereby a gap is formed between the conveyor 114 and the pressure unit 124 - 130 The sample 116, 146 transported by the conveyor 114 can thus pass through the supply switch 1240 - 1280 in connection with the following supply unit 106 - 110 found.
    The supply switches 1240 - 1280 can be controlled fixedly and upwards with a control device 152. Although not shown in Figure 1, a corresponding switch may also be located in connection with the supply device 150.
    In the feeding device 100, the sample 116, 146, 156 can be pushed into the feeding unit 106 - 110, 150 in such a way that the sample 116, 146, 156 is penetrated under the pressure unit 124 - 130. The user can do this manually or the feeding unit 106 - 110, 150 can pull the sample 116, 146, 156 placed in the feeding unit suitably far in readiness for feeding into the measuring device. Each feed unit 106 - 110, 150 is designed so that a gap can remain between the sample 116, 146, 156 and the conveyor 114 if the printing unit 124 - 130 is not positioned to press the sample 116, 146, 156 against the conveyor 114. In this case the supply switch 1240 - 1280 is considered to be open. The feeder 100 thus holds the sample 116, 146, 156 and the conveyor 114 physically separated if the pressure unit 124 - 130 is not controlled or positioned to push the sample 116, 146, 156 against the conveyor 114. If the feed unit 106 - 110, 150 does not contain a sample 116, 146, 156, the pressure unit 124 - 130 can be kept separate from the conveyor 114. This enables transport of the sample 116, 146, 156 from a rear feed unit past the front feed unit to the measuring device 102.
    When it is desired to surface the sample 116, 146, 156 in the feed unit 106 - 110, 150 for measurement, the feed unit 106 - 110, 150 printing unit 124 -130 can be placed to press the sample 116, 146, 156 against the conveyor 114. In that case the friction between the conveyor 114 and the sample 116, 146, 156 carries the sample 116, 146, 156 with it towards the receiving opening 104. Additionally or alternatively, the conveyor 114 (the conveyor belt) may have projections 148, which penetrate the sample 116, 146, 156 and strengthen the conveyor 114. grip on the sample 116, 146, 156. The protruding conveyor belt 114 may be e.g. a nail tape.
    Each feed unit 106 - 110 may comprise at least one restrictor 118, 120, 122, which may prevent the sample 116, 146 from withdrawing from under the pressure unit 124 - 130 when the feed unit 106 - 110 is not holding and feeding samples onto the conveyor 114. This ensures that the sample 116, 146 placed in each feeding unit 106 - 110 can be pressed with the printing unit 124 - 130 against the conveyor 114 and thus fed in at the desired time for measurement.
    Although not shown in the figures, the feed unit 150 may also comprise a limiter. At least one feed unit 106 - 110 may comprise a holder 132, 134, 136 for a cylinder 138 - 142. The rigid cylinder 138 - 142, which may be e.g. of metal or plastic, acts as a support for the sample 146 in the center of the roll. The at least one feeding unit 106 - 110 can feed the sample 146 rolled on the cylinder 138 - 142 into the conveyor 114 against measurement. At least one feed unit 106-110 may comprise a sample support 144 for a sheet-like sample 116. The sample support 144 supports the sheet-like sample 116, whereby it can be easily fed with the feed unit 106-110 onto the conveyor 114 against measurement. The test support 144 may be e.g. a metal or plastic plate, which is attached to the feed unit. The feeding device 100 can be used in such a way that the user settles next to all feeding units 106 - 110 when placing the sample 116, 146 to each of the feeding units 106 - 110. The feeding units 106 - 110 height position can be arranged according to the user, whereby the feed units 106 - 110 can be located at a height of e.g. about 90 cm from the floor. This improves ergonomics.
    It is possible to feed samples automatically with the feeding device 100 into the measuring device 102 for analysis. The automatic feeding and analysis of several samples can take tens of minutes. Different samples can be prioritized and the samples can be entered in the order of priority for measurement.
    If you want an ongoing measurement process to analyze a new sample, the ongoing measurement process can be interrupted. The feeding device 100 can interrupt a predetermined sample transmission process and feed the interrupting sample 116, 146 into the measuring device 102. This can be done e.g. if you want to analyze a new sample surprisingly and quickly. After the interruption, the predetermined test transmission process can be continued from the point where it remained before the interruption. The interruption can be performed by the user giving an interrupt command via a user interface 154. Once the interrupting sample or samples have been entered into the measuring device 102, the interrupted feeding program can be continued automatically or after a command given by the user.
    An open roll constituting the sample 156 can be fed in for analysis from the end of the feeding device 100 and the end of the feeding device 100 can thus also function as a feeding unit 150. The open roll can be a sample taken long in the machine direction and wrapped on a loose roll rigid cylinder as support in the middle. The sample can be paper or cardboard. When feeding sheet samples which deviate from the standard size and which are in particular smaller than the standard size, a separate sample base can be used as an aid (not shown in the ur gures), to which the sheet 116 acting as sample 116 can be attached. The sample base is dimensioned in such a way that it can be fed in for analysis also as the open roll 156 from one end of the feeding device 100, which acts as a feeding unit 150. The open roll 156 and sample base can be fed with the feeder 100 for analysis. Both the open roller 156 and the sample base are pushed between the printing unit 130 and the conveyor 114 in readiness for feeding into the measuring device 102.
    The pressure unit 130 and the conveyor 114 constitute a supply switch 1300, which functions in the same way as the supply switches 1240 - 1280.
    When feeding both the open roll and the sample base, the feed units 106 - 110 can be passed by keeping the feed switches 1240 - 1280 open.
    Figure 3 shows a fate diagram for the procedure. In step 300, a sample 116, 146 is sent with the at least one feeding unit 108 - 110, 150 of the feeding device 100 against a measurement performed in the measuring device 102. In step 302, the transmitted sample 116, 146 is guided past at least one feed unit 106-110 following the feed route, and is located in the feed direction between said at least one feed unit 108-110 and the measuring device 102.
    The control device 152, which may comprise a processor, memory and one or more computer programs suitable for the purpose, which in turn can control the operation of the feeding device 100, to which belong the steps shown in the fate diagram. In addition, the user can influence at least some measures performed by the control device 152 via the user interface 154 operatively connected to the control device 152 or directly manually control the feeding device 100. The user can interrupt the feeding program and feed an interrupting sample or interrupting samples into the measuring device or a suitable feeding unit. .
    Although the invention has been described above with reference to the example according to the accompanying drawings, it is clear that the invention is not limited thereto, but may be modified in many ways within the scope of the appended claims.
