Description

"Installation for measuring bearing wear in

  guidance of transfer facilities "

  The invention relates to an installation for

  accurately monitor in position, the wear caused by the rolling in guide channels of

  transfer, in particular installation guide channels

  transfer lations with multiple link chains

  nis of gripping elements rolling in a closed circuit, and which transfer printing products according to a chain of printing product, arranged in scales, of the

  printing machine up to inter storage units

medium and / or dispatch.

  According to document DE-26 29 528 there is known a transfer installation comprising a chain with links and ball joints; the links have at one end in the form of a fork, a hinge body in

  shape of a segment of a sphere and at the other end a

  hinge shovel surrounding the next link element

of the joint body.

  Each ball or ball joint is mutually

  nie of a horizontal axis starting from the fork-shaped ends for two rolling wheels circulating on a support and supported by the flanges of a guide channel having substantially a C shape. A respective arm is fixed to the chain link ; this arm has a laterally projecting rod

  relative to the link to fix the product to be transported.

  The fixing rod, laterally projecting, causes the links to seize in the guide channel so that one of the two rolling wheels of each link does not press against the flange on the side opposite the fixing rod but against the branch located at the top of the guide channel. Each link in the chain takes a position

  offset so that you cannot get a static position

ble without chain tensioner.

  There is no beat, no jerk induced in

  chain, during start-up or re-operation

  gime. Even some transfer facilities

  length work without noise, without it being necessary

  be able to tighten the chain by complementary means.

  This transfer facility allows

  smooth transfer problems but also

  Generally speaking, training problems in the

  point of view of guiding the chains in space.

  However, the drawback of this transfer installation is that it does not make it possible to detect the wear caused by the bearing, in particular in the case of transfer installations of a certain length, except

  at the cost of implementing significant technical means

aunts.

  The object of the present invention is to create an installation making it possible to measure the wear without requiring the use of significant technical means and in particular for precise measurement in position in

  transfer facilities of a certain length.

  To this end, the invention relates to an installation

  tion corresponding to the type defined above, characterized in that at least in the tracks of the various running wheels of the link chain, is articulated a system of detection wheels elastically mounted with respect to each other, each wheel of detection of a trace of

  bearing wheel being connected to the detection wheel res-

  pectively neighboring by means of a connection installation mounted in rotation and in that the travel of the detection wheels for the detection of the measurement of wear, is ensured by sensors generating electrical signals and these sensors are tracked of an installation

  of operation to associate the general electrical signals

  res by the sensors at the respective position of the sensors with respect to the guide channel in the transfer installation and for determining signals for detecting the

  sensors, the signals being predetermined over time.

  According to other interesting characteristics

  tes: - the operating installation includes a transmission / reception installation composed of a signal transmitter

  pulses associated with the installation guide channel

  transfer lation and a receiver associated with the link chain, the operating installation includes an installation

  transmission / reception formed by an im-

  multi-channel drives associated with the link chain and a receiving installation provided in the guide channel of the transfer installation,

  - the operating installation consists of sensors

  for proportional detection over time and storage of the chain link sensors, which are associated with a memory used for the proportional storage of travel values over time

  detection wheels, values detected by the cap-

  teurs, - on at least two detection wheels, at least one wheel

  is articulated on a wheel track

  Lement and / or at least each time a detection wheel is located outside the track of the rolling wheel in the guide channel of the transfer installation, parallel in the direction of circulation and in that at the following the sensors, there is an operating installation used to associate the electrical signals generated by the sensors with the respective position of the

  sensors relative to the installation guide channel

transfer lation.

  The present invention will be described below in

  using an embodiment shown schematically-

  ment in the accompanying drawings in which:

  - Figure 1 is a schematic overview of the ins-

  tallation, - Figure 2 is a schematic sectional view of the guide channel and the measuring installation and a view

  in schematic side section A-A of the measuring device

  safe. In the case of the entire installation of

  transfer shown in figure 1, appear the rela-

  functional with this installation.

  Figure 1 shows the schematic layout

  of the wear measurement unit 9 composed of the detection wheels

  tion 2, the connection installation 3 and the sensor 4 as well

  if that from memory 5 downstream and the installation of

  reception 8 following memory 5.

  These assemblies are provided at the level of the

  guidance of the transfer installation. Before-

  The values of the voltage proportional to the wear are always recorded as maximum values of

  the elapsed measurement period and serve as com-

parison for the next measurement.

  Figure 2 shows a schematic section of the case.

  guide 1 and the measuring device.

  This figure shows the running wheels 2 of the two halves of the measuring system. The two halves

  are connected in rotation by the connection installation 3.

  Thus one can have any curvature as well as a twist of the guide channel without seizing of the sensor 4 and

  thus without risk of distorting the measurement value.

  For the two running wheels 2 of each half of the measuring system, there is each time a wheel which follows the trace and a wheel on the auxiliary surface; each running wheel is mounted on a spring and can

  wrestle independently of the other.

  The measurement of the clearance is explained by the section A-A; this travel is captured by the sensor 4 which

  transmits the signal to memory 5.
